DETAILED DESCRIPTION

[0044] The invention will now be described more specifically with reference to the following non-limiting examples. It is to be noted that the following embodiments are presented herein for purpose of illustration and description only. It is not intended to be exhaustive or to be limited to the precise form disclosed.

[0045] It is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including,” “comprising,” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof, as well as additional items. Unless specified or limited otherwise, the terms “mounted,” “connected,” “supported,” and “coupled” and variations thereof are used broadly and encompass both direct and indirect mountings, connections, supports, and couplings. Further, “connected” and “coupled” are not restricted to physical or mechanical connections or couplings.

[0046] Track switches are commonly used to allow train cars to change from one track to another, for example, to bypass a portion of a main rail line that is undergoing maintenance, to store cars on a stub track, or to act as a turnout for delivery of goods away from the main line. However, existing track switches are subject to many shortcomings. For example, installation of existing switches requires cutting into a main track, leading to long installation times, interruptions in the usability of the main track, increased maintenance, and high costs. Due to these shortcomings, traditional switching methods tend to be permanent in nature and are typically not cost effective for tracks that serve smaller industries or that are used infrequently.

[0047] FIG. 1 illustrates one non-limiting example of a track switch 10 according to aspects of the present disclosure. The track switch 10 includes a turntable section 12, one or more track sections 14 having varying lengths and curvatures, and a pair of ramp sections 16. Each of the ramp sections 16 may include a pair of laterally opposing rail clamps 17 that allow the track switch 10 to selectively couple to an existing railroad track.

[0048] The track sections 14 and the ramp sections 16 are coupled with one another to form and act as a single line of track, thereby permitting, for example, a railcar or locomotive, to travel across the track switch 10. The turntable section 12 is configured to connect with one of the track section 14, forming a rotatable connection. This connection allows the track sections 14 and the ramp sections 16 to rotate relative to the turntable section 12 between a closed position and an open position.

[0049] Additionally, a plurality of support frames 18 may be positioned generally adjacent to and/or underneath the track switch 10. The support frames 18 may provide vertical support to and a stable base for the track sections 14. The number and location of support frames 18 can vary depending on the requirements of the specific installation, including, but not limited to, soil conditions and types, drainage requirements, the length and shape of the track sections 14 being used, and the distance between the railroads that the track switch 10 is intended to connect.

[0050] FIG. 2 shows another non-limiting example of a track switch 10, according to aspects of the present disclosure. In the illustrated non-limiting example, the track switch 10 includes actuator brackets 22 attached to the side of the turntable section 12. The actuators 24 (e.g., hydraulic actuators) may be connected between the actuator brackets 22 and one of the track sections 14. Specifically, the actuators 24 may be coupled between the turntable section 12 and the track section 14 that is coupled to the turntable section 12. In this way, for example, the actuators 24 are configured to selectively rotate the track switch 10 between an open position and a closed position. In the illustrated non-limiting example, the actuators 24 are arranged on a common side of the turntable section 12. In other non-limiting examples, the actuators 24 may be arranged on laterally opposing sides of the turntable section 12 (see FIG. 4). In the illustrated non-limiting example, one of the actuators 24 may push (e.g., extend) the track section 14 coupled thereto and the other actuator 24 may pull (e.g., retract) the track section 14 during rotation of the track switch 10.

[0051] FIG. 3 shows another non-limiting example of a track switch 10, according to aspects of the present disclosure. In the illustrated non-limiting example, the track switch 10 includes a track connection bracket 26 at each intersection between the track sections 14 and between the track section 14 and the ramp sections 16. The track connection brackets 26 may be configured to securely couple the track sections 14 and the ramp sections 16 together to form a single track. In other non-limiting examples, the track sections 14 and the ramp sections 16 may be coupled to one anther via interlocking features present on the sections themselves.

[0052] In the illustrated non-limiting example, an actuator bracket 27 is coupled to one of the support frames 18. The actuator bracket 27 houses an actuator 25 that may be coupled to one of the track sections 14. Arranged in this manner, the track switch 10 can be rotated about the turntable section 12, between a closed portion and an open position, by extend or retracting the actuator 25.

[0053] In general, the various component of the track switch 10 may be customized to suite a particular railroad application. For example, the arrangement of the turntable section 12 may be varied along the track switch 10 to alter the location of a pivot point defined by the track switch. For example, in some non-limiting examples, the turntable section 12 may be arranged generally adjacent to a longitudinal middle of the track switch (see, e.g., FIGS. 1, 2, 4, 5). Alternatively, the turntable section 12 may be arranged generally adjacent to one end (see, e.g., FIGS. 3, 6, 7) of the track switch (e.g., adjacent to one of the ramp sections 16). One or more actuators may be coupled to a corresponding number of the track sections to enable rotation of the track switch 10, as long as the actuator is arranged a distance away from the pivot point. It should be appreciated that in some non-limiting examples, the track switch 10 may be rotated by an external component not directly coupled to the track switch. That is, the track switch 10 may not include an actuator coupled to a track section (see, e.g., FIG. 1), and the track switch 10 may be selectively rotated by an external device (e.g., an off-highway vehicle or forklift).

[0054] FIG. 4 shows another non-limiting example of a track switch 10 in an open position, according to aspects of the present disclosure. In the illustrated non-limiting example, the turntable section 12 includes two actuators 24 coupled to laterally opposing sides thereof. In this non-limiting example, both of the actuators 24 may extend to rotate the track switch 10 from a closed position (see FIG. 5) to the open position (FIG. 4), or both of the actuators 24 may retract to rotate the track switch 10 from the open position (FIG. 4) to the closed position (FIG. 5).

[0055] In the open position, the track switch 10 is rotated such that the ramp sections 16 are aligned with and provide a path between a first existing track 28 and a second existing track 29. That is, the ramp sections 16 may be rotated to the open position where the ramp sections 16 align with the first existing track 28 and the second existing track 29. With one of the ramp sections 16 aligned with the first existing track 28 and the other ramp section 16 being aligned with the second existing track 29, a railcar or locomotive is able to travel along the first existing track 28, across the track switch 10, and onto the second existing track 29, or visa versa. In doing so, the railcar or train will travel onto a ramp section 16, across the various track sections 14, and finally off the other ramp section 16. Additionally, when in the open position, each of the rail clamps 17 is coupled to the respective one of the first existing track 28 and the second existing track 29, thereby preventing the track switch 10 from rotating out of the open position.

[0056] FIG. 5 shows the track switch 10 of FIG. 4 in a closed position. In the closed position, each of the rail clamps 17 is disengaged from the first existing track 28 and the second existing track 29. With the rail clamps 17 disengaged, the track switch 10, and the ramps sections 16, can be rotated away from both of the first existing track 28 and the second existing track 29, so that the ramp sections 16 are not in alignment and do not overlap with the first existing track 28 and the second existing track 29. Due to the misalignment and non-overlapping arrangement between the ramp sections 16 and the first existing track 28 and the second existing track 29, a railcar or locomotive, or other object traveling down the railway, would be unable to traverse across the track switch 10. That is, the track switch 10 does not alter the travel along the first existing track 28 and the second existing track 29 in the closed position. As such, a railcar or locomotive to travel on the first existing railroad track 28 or the second existing track 29 would be able to continue down the respective track uninhibited.

[0057] With regard to both FIG. 4 and FIG. 5, it is preferable that an adequate number of support frames 18 are used, and arranged in such a manner, so as to ensure all of the track sections 14 and the ramp sections 16 are supported. For example, one or more support frames 18 may be arranged between the first track section 28 and the second track section 29 to provide support for the track sections 14 that are not supported by the turntable section 12, and for the ramp sections 16 when the track switch is in the closed position.

[0058] FIG. 6 shows another track switch 10, in an open position, according to aspects of the present disclosure. In the open position, the track switch 10, and the ramp sections 16, is rotated such that the ramp sections 16 are aligned with and rest upon the first existing track 28 and the second existing track 29. With one of the ramp sections 16 aligned with the first existing track 28 and the other ramp section 16 being aligned with the second existing track 29, a railcar or locomotive is able to travel along the first existing track 28, across the track switch 10, and onto the second existing track 29, or visa versa. In doing so the railcar or train will travel onto a ramp section 16, across the various track sections 14, and finally off the other ramp section 16. Additionally, when in the open position, each of the rail clamps 17 is coupled to the respective track 28, thereby preventing the track switch 10 from rotating out of the open position.

[0059] In the illustrated non-limiting example, the pivot point defined be the position of the turntable section 12 along the track switch 10 is arranged adjacent to one of the ramp sections 16 (e.g., the right ramp section 16 from the perspective of FIGS. 6 and 7). The track switch 10, and the ramp sections 16, may be rotated between the open position and a closed position (FIG. 7) by an external device that is configured to provide a force on one of the track section 14 and rotate the ramp sections 16 about the pivot point in the turntable section 16. Alternatively or additionally, the track switch may include one or more actuators as described herein to selectively rotate the ramp sections 16 between the open position and the closed position.

[0060] FIG. 7 shows the example track switch 10 of FIG. 6 in a closed position. In the closed position, each of the rail clamps 17 is disengaged from the first existing track 28 and the second existing track 29. With the rail clamps 17 disengaged, the track switch 10, and the ramps sections 16, can be rotated away from one or more of the first existing track 28 and the second existing track 29, so that the ramp sections 16 are not in alignment and do not overlap with the first existing track 28 and/or the second existing track 29. Due to the misalignment and non-overlapping arrangement between the ramp sections 16 and the first existing track 28 and/or the second existing track 29, a railcar or locomotive, or other object traveling down the railway, would be unable to traverse across the track switch 10.

[0061] In this specific non-limiting example, the track switch 10 is entirely separated from only the second existing track 29, with one of the ramp sections 16 remaining in an overlapped but misaligned arrangement with the first existing track 28. As such, a railcar or locomotive would be able to travel on the second existing track 29 when the track switch is in the closed position.

[0062] FIGS. 8 and 9 illustrate an example turntable section 12, according to aspects of the disclosure. The turntable section 12 includes a ballast frame 30 having at least two longitudinal members 32 connected by a plurality of cross members 34, a bearing base plate 36, a pivot pin 38, and a bearing plate 40. Depending on the desired configuration, the bearing base plate 36 may include one or more individual plates.

[0063] The ballast frame 30 defines a bottom portion 42 configured to rest on the ground, and a top portion 44 configured to connect with and support the bearing base plate 36. Additionally, the ballast frame 30 may include various attachment or lifting points 46 for moving, transporting, or installing the turntable section 12.

[0064] The pivot pin 38 is coupled with and extends upwardly from bearing base plate 36. The bearing plate 40 defines a hole 46 which receives the pivot pin 38, forming a rotatable connection that allows the bearing plate 40 to rotate relative to the bearing base plate 36 and the ballast frame 30. The bearing plate 40 may come in various shapes, however is it preferably circular and may include a number of indented portions 48 on the outer circumference. The indented portions 48 may be used, for example, to aid in locating the track switch 10 in an open or a closed position. The bearing plate 40 is supported by the bearing base plate 36.

[0065] The turntable section also includes the actuator brackets 22 attached to the ballast frame 30. Here, two actuator brackets 22 are coupled to the same longitudinal member 32 on one side of the frame 30. However, the number and position of the actuator brackets 22 can vary depending on the configuration of the track switch 10 being used. For example, in some cases there may be no actuator bracket 22, or there may only be one. Further, where multiple brackets 22 are used, the brackets 22 do not need to be located on the same side of the ballast frame 30, and may be located on different longitudinal members 32, so that the brackets 22 are disposed on opposite sides of the ballast frame 30.

[0066] FIGS. 10 and 11 show an example bearing plate 40, according to aspects of the disclosure. The bearing plate 40 is generally circular in shape and includes a central hole 46 configured to receive the pivot pin 38 of the turntable section 12. A rotatable connection is formed by inserting the pivot pin 38 in the hole 46, which permits the bearing plate 40 to rotate around the pivot pin 38. When the pivot pin 38 is received by the hole 46, the bearing plate 40 is disposed adjacent to the bearing base plate 36. It should be noted that oils, greases or other lubricants may be placed between the bearing plate 40 and the bearing base plate 36 to reduce friction as the bearing plate 40 rotates.

[0067] The bearing plate 40 may also include various indented portion 48, disposed around the outer perimeter of the bearing plate 40. In this case, there are four indented portions 48, however there may be more or less. Furthermore, while the indented portions 48 shown here are semi-circular in shape, the indented portions 48 may take on a variety of shapes depending on what is required by the application.

[0068] It should be understood and appreciated, as will become apparent in the present disclosure, that the track sections 14 do need not be a single length or shape. Rather, some track sections 14 may be considered long, and others comparatively short. Furthermore, some track sections 14 may be straight, while others may be curved. The number, length, and curvature of the track sections 14 used will be determined by the specific application of the track switch 10 and the existing track sections being selectively connected by the track switch 10.

[0069] Referring to FIGS. 12 and 13, an example track section 14 is shown according to aspects of the disclosure. The track section 14 includes a track base plate 50 and a track 52. The track base plate 50 defines a bottom surface 54, a top surface 56, two sides 58 and 59, and a first distal end 60 and a second distal end 61. The track base plate 50 is a generally longitudinal flat plate, having a hole 62 extending through the track base plate 50.

[0070] The hole 62 is configured to receive the pivot pin 38 of the turntable section 12, establishing a rotatable connection between the track section 14 and the turntable section 12 about the pivot pin 38. When the hole 62 of the track base plate 50 receives the pivot pin 38, the bottom surface 54 of the track base plate 50 is disposed adjacent to the bearing plate 40 of the turntable section 12. While multiple track sections 14 that are capable of receiving a pivot pin 38 may be used, only one of the track sections 14 receives the pivot pin 38. Thus, the track sections 14 in a given assembly of the track switch 10 may be assembled in a modular fashioned and the pivot point may be determined by the position of the turntable section 12 and the particular track section 14 that receives the pivot pin 38. In some non-limiting examples, some of the track sections 14 may include a hole 62, and others may not, as long as one of the track sections 14 is capable of receiving the pivot pin 38.

[0071] While the hole 62 is shown here to be disposed generally in the center of the track base plate 50, the hole 62 may be placed anywhere on the track base plate 50. By having the hole 62 located for example, near distal end 60, the center of rotation of the track switch 10 can be adjusted to fit a specific application of the track switch 10.

[0072] The track 52 is configured to allow, for example, a railcar or locomotive, to travel along the track 52. The track 52 is fixedly connected to the top surface 56 of the track base plate 50 and runs along the length of the track base plate 50 from one distal end 60 of the track base plate to second distal end 61 of the track base plate 50.

[0073] The distal ends 60 and 61 of the track base plate 50 are each configured to connect and align with a distal end 60 or 61 of another track base plate 50 or a ramp section 16. As shown here, threaded holes 64 are disposed in the track base plate 50, adjacent to each distal end 60 and 61 of the track base plate 50. The threaded holes 64 may be configured to align with corresponding holes 65 of the track connection bracket 26 (see FIG. 17). When the holes 64 are aligned with the holes 65 of the track connection bracket 26, the track section 14 can be coupled with another track section 14 via track connection bracket 26 and plurality of fasteners. However, other means of connecting track sections 14 may be utilized, for example, connecting with fasteners only, or by welding abutting track sections 14 together, or by having interlocking connectors configured to connect the tracks without the use of additional hardware.

[0074] Additionally, the track section 50 may include offset alignment bars 66, which are configured to help align abutting track sections 50, so that the respective tracks 52 are in linear alignment with one another. In some non-limiting examples, the track section 14 may include a plurality of attachment or lifting points 68 for moving, transporting, or installing the track section 14

[0075] Referring to FIGS. 14 and 15, another example track section 14 is shown according to aspects of the disclosure. In the present embodiment, track section 14 is curved longitudinal member. The tracks 52 are configured to have a curvature which corresponds to the curvature of the track base plate 50. The curvature of the track section 14 can vary as needed to allow the track switch 10 to connect to a variety of existing railroad tracks 28.

[0076] In general, the track sections 14 may vary in length and curvature, as illustrated herein, to provide a single track that extends between the ramp sections 16. As such, the track sections 14 may be customized to fit a particular existing track arrangement and/or a particular distance between existing tracks.

[0077] FIG. 16 shows an example track section 14 that is coupled to the turntable section 12. In the illustrated non-limiting example, the pivot pin 38 is received by the hole 62 in the track section 14. The actuators 24 are coupled with both the actuator brackets 22 and the track section 14. The track section 14 is coupled to the actuators 24 at brackets 70. In this arrangement, the actuators 24 are configured to extend and retract to enable rotation of the track section 14, and thereby rotation of the ramp sections 16 between the open position and the closed position.

[0078] FIG. 17 shows an example track connection bracket 26, according to aspects of the disclosure. The track connection bracket 26 defines holes 65 that correspond to holes 64 of the track section 14. When the holes 65 are aligned with the holes 64 of the track section 14, a fastener can be inserted into the respective holes 64 and 65 to couple the track connection bracket 26 with two track sections 14, or to couple a track section 14 to a ramp section 16 (see FIG. 3).

[0079] FIGS. 18-25 show an example ramp section 16 according to aspects of the disclosure. The ramp section 16 is comprised of a ramp base plate 74, a ramped track 75, guard rails 76, and a pair of rail clamps 17. The ramp base plate 74 includes a bottom face 77 configured to rest atop a railroad track 28, a top face 78, a first distal end 79, a second distal end 80 each configured to connect with a track section 14, and two sides 81 and 82 (see FIG. 21-22). The bottom face 77 of the ramp base plate 74 may also include ramp stops 83 attached to the bottom face 77 to assist in aligning the ramp section 16 on the railroad track 28.

[0080] Referring specifically to FIGS. 21-23, the ramp base plate 74 further defines a ramped portion 84 at the first distal end 79 that extends from a substantially pointed region 85 nearest the first distal end 79 and the bottom face 77. The ramped portion 84 slopes upwardly at an angle to the top face 78, in the direction of the second distal end 80. The top face 78 of the ramp base plate 74 may be coupled to lifting points 86 to aid in moving the ramp section 16 during transport or installation.

[0081] The ramped track 75 is comprised of two parallel ramped rails, each defining a bottom surface 87 and a sloped top surface 88 which forms a generally pointed end 89, and a wide end 90 (see FIGS. 24 and 25). The angle of the sloped top surface 88 corresponds with the angle of the ramped portion 84 of the ramp base plate 74. The ramped track 75 is coupled with the ramp base plate 74, so that the bottom surface 87 of the ramped track 75 is in contact with the top surface 78 of the ramp base plate 74.

[0082] The ramped track 75 is oriented such that the pointed ends 89 of the ramped track 75 are disposed adjacent to the ramped portion 84 of the ramp base plate 74. The ramped track 75 extends along the length of the ramp base plate 74 toward the second distal end 80 of the ramp base plate 74. Oriented in this manner, the ramped portion 84 of the ramp base plate 74 and the sloped top surface 88 of the ramped track 75 form a generally continuous upward slope, beginning at the first distal end 79 of the ramp base plate 74 and terminating at the second distal end 80.

[0083] The guard rails 76 run parallel with the ramped track 75. In this case, there are four guard rails 75, with two being disposed to the interior of the track 75 and two being disposed to the exterior of the track 75 adjacent the sides 81 and 82. However, fewer than four guard rails 75 may be used, for example, there may only be two guards rails 75, which are both disposed to the interior of the track 75.

[0084] Each guard rail 76 includes a bottom surface 91 coupled with the top surface 78 of the ramp base plate 74, and a sloped top surface 92 corresponding with the sloped top surface 88 of the ramped track 75 such that the top surface 88 of the ramped track 75 and the top surface 92 of the guard rails 76 are generally aligned. In some embodiments, the top surface 92 of the guard rails 76 may be higher or lower than the sloped top surface 88 of the ramped track 75. The guard rails 76 may also include gussets, braces, or other support structures to provide additional strength and rigidity. Each one of the pair of rail clamps 17 is attached to a respective side 81 and 82 of the ramp base plate 74 at a lock pivot bracket 93 that is coupled to the ramp base plate 74.

[0085] FIG. 26 shows and example rail clamp 17, according to aspects of the present disclosure. The rail clamp 17 comprises a pivot bar 94, a handle 95, and one or more locking plates 96. The pivot bar 94 is a cylindrical rod that is configured to be fixedly coupled to the lock pivot bracket 93, and extends parallel to the sides of the ramp base plate 74. The handle 95 is configured to receive the pivot bar 95, thereby allowing the handle 95 to rotate about the pivot bar 94.

[0086] Each of the locking plates 96 are fixedly connected with the handle 95 and define a hole 97 through which the pivot bar 94 extends. Each of the locking plates 96 defines a channel 98 configured to receive and connect with the railroad track 28. The handle 95 and the one or more locking plates 96 rotate as a single unit about the pivot bar 94 between an unlocked position, where the rail clamp 17 is not in contact with an existing track, and a locked position, where the channel 97 of the one or more locking plates 96 couples with an existing track, thereby securely connecting the ramp section 16 with the railroad track 28.

[0087] FIG. 27, shows an example support frame 18, according to aspects of the disclosure. The support frame 18 has two longitudinal members 98 connected by a multitude of cross members 99. The support frame 18 defines a bottom portion 100 near the longitudinal members 98, configured to provide a stable connection with the ground. The support frame 18 further defines a top portion 101 adjacent the cross-members 99, configured to provide support to the bottom face 54 of a track base plate 50 or a bottom face 77 of a ramp base plate 74, thereby providing vertical support to the track sections 14 and ramp sections 16. Additionally, depending on the configuration of the track switch 10, the support frame 18 may also include attachment brackets 22 for an actuator system 24, for example, a hydraulic actuator, and/or lifting points 102 to facilitate movement of the support frame 18 during transport and installation.

[0088] It should be understood and appreciated that any number or configuration of support frames 18 may be utilized, depending on the requirements of the specific use case scenario. Any support frames 18 are preferably arranged to provide support to the various track sections 14 and ramp sections 16 of the track switch 10 so that the track switch 10 is fully supported anywhere between the open position and the closed position.
