DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

(8) An embodiment of the present invention is illustrated in FIG. 1 and provides a number of advantages over prior art linear winches, specifically by providing robust and sturdy gripper assemblies, components of which are capable of being moved out of the pathway of a cable connector such as a socket so that the connector may pass through the winch. The linear winch is capable of performing a wide range of winching and tasks in a safe and time efficient manner.

(9) FIGS. 1A and 1B shows perspective views of linear winch assembly 10. The linear winch assembly 10 has a housing 12. One side of the winch assembly in FIG. 1B has been removed to improve the clarity of the drawing. The winch housing 11 can be seen to comprise a first gripper assembly 14 and a second gripper assembly 16. The first gripper assembly 14 and a second gripper assembly 16 are slidably mounted within housing 12.

(10) Hydraulic cylinders 18 and 20 are mounted in the housing 12 and are connected to the gripper assemblies 14 and 16 respectively. The gripper assembly 14 is configured to be moved in reciprocating action along the longitudinal axis of the housing 12 by the extension and retraction of hydraulic cylinder 18. The gripper assembly 16 is configured to be moved in reciprocating action along the longitudinal axis of the housing 12 by the extension and retraction of hydraulic cylinder 20.

(11) The gripper assemblies 14 and 16 are designed to engage and grip a cable 17. The hydraulic cylinders 18 and 20 are configured to move the gripper assemblies and the gripped cable 17 along the longitudinal axis of the linear winch assembly.

(12) FIG. 1B shows hydraulic cylinder 18 in a fully extended position and hydraulic cylinder 20 in a fully retracted position. A connector socket 19 is used to connect two sections of cable 17a and 17b. The socket 19 is shown in FIG. 1B positioned close to the gripper assembly 14 but is unable to pass though the gripper assembly 14 as there is not sufficient clearance to allow the socket 19 to pass through gripper assembly 14.

(13) FIGS. 2A and 2B shows an enlarged perspective view of the gripper assembly 14. The gripper assembly 14 comprises a gripper housing 24 having a base 24a and four walls 24b, 24c, 24d and 24e. Wall 24e has been removed from FIG. 2 to improve the clarity of the drawing. The walls 24b and 24d are perpendicular to the longitudinal axis of the winch assembly and have slots 26 which are dimensioned to allow a cable 17 and socket 19 to pass through the walls 24b and 24d.

(14) Hydraulic cylinder 18 is connected at one end to the wall 24b of the gripper housing 24 and is configured to slidably move the gripper housing 24 along the longitudinal axis of the winch housing 12.

(15) The gripper housing 24 comprises a lid section 28a and a gripper block 28b. The lid section 28a is slidably mounted on the gripper block 28b. Hydraulic cylinders 21 and 23 are connected to the gripper block 28b and are configured to engage with lid members 29 to slide the lid section 28a relative to the gripper block 28b along the longitudinal axis of the housing 12 by the extension and retraction of hydraulic cylinders 21 and 23. The lid section 28a is configured to be slidably moved between a locked position shown in FIG. 2A and an unlocked position shown in FIG. 2B.

(16) The lid section 28a is pivotally and slidably mounted on the gripper housing 24 via a rod 34 which is connected to the walls of the gripper housing 24. A hydraulic cylinder 36 is connected to rod 34 via a coupling 37. The rod 34 has a hexagonal cross-section. The hydraulic cylinder 36 and coupling 37 are configured to engage rod 34 to pivotally move the lid section 28a between open and closed positions. Although, this example shows a hexagonal cross-section rod and hydraulic cylinder to pivotally move the lid section between open and closed positions it will also be clear that other rod cross sections and/or other mechanisms may be used.

(17) The gripper block 28b is movably mounted on guide rails 30 via guide wheels 31 mounted on a base section of the gripper block 28b. Hydraulic cylinders 32 and 33 are connected at one end to the gripper block 28b and to the base 24a of the gripper housing 24 at the other end. The hydraulic cylinders 32 and 33 are configured to move the gripper block 28b along the sloped pathway of the guide rails 30. By moving the guide wheels 31 of the gripper block 28b along the sloped pathway of the guide rails 30 the gripper block 28b is lowered out of the pathway of the cable 17 and/or socket 19.

(18) Although, this example shows guide rails 30 and guide wheels 31 are used to lower the gripper block 28b out of the pathway of the cable 17 and socket 19 other guide arrangements and/or mechanisms may be used. It will also be clear that other assembly components may be moved in other directions to move the assembly out of the pathway of the cable 17 and socket 19.

(19) The lid section 28a and gripper block 28b have a wedge shape. The dimensions of the lid section 28a and gripper block 28b are such that when the wedge shape lid section 28a is positioned on top of the corresponding wedge shape gripper block 28b and moved by the actuation of hydraulic cylinders 21 and 23 in a general direction Y along the longitudinal axis of the housing 12, the inner surfaces of the wedged shape lid section 28a bears against the outer surfaces of the wedged shape gripper block 28b. In this position the lid is clamped onto the gripper block 28b. FIG. 2A shows the lid section 28a in a clamped position.

(20) However, actuation of hydraulic cylinders 21 and 23 to move lid section 28a in a general direction Z along the longitudinal axis of the housing 12 causes the inner surfaces of the wedged shape lid section 28a to move away from the outer surfaces of the wedged shape gripper block 28b. In this position the lid is released from the gripper block 28b. FIG. 2B shows the lid section 28a in a released position.

(21) FIGS. 3A, 3B and 3C show an enlarged plan, perspective and cross-sectional views of the gripper assembly 14. The lid section 28a has been removed for clarity. The gripper block 28b comprises two parallel bearing members 42 mounted on the gripper block 28b in a generally wedged shape. The gripper block 28b comprises a gripper slider 44 which houses two clamp members 46.

(22) The clamp members 46 have inner faces 46a which have longitudinal semi-cylindrical grooves 46b that are dimensioned to receive the cable 17. The size and shape of the semi-cylindrical grooves 46b may be changed for different cable sizes and/or types.

(23) The gripper block 28b is configured to restrain and grip the cable 17 and pull the cable in a first direction as shown by arrow Y in FIG. 3A and to release the cable and allow the cable to move freely relative to the gripper block in the opposite direction of travel represented by arrow Z in FIG. 3A.

(24) The outer surfaces 46c of the clamp members 46 have a wedge shape. The clamp members 46 are configured to move perpendicular to the longitudinal axis of the housing 12 to bear against bearing members 42 when the gripper block 28b is moved in a general direction Y. When the movable clamp members are moved in the direction Y, they transmit a force to the bearing members 42. The bearing members 42 are fixed in the base section of the gripper block 28b which causes a reaction force against the inner surfaces of the clamp members 46 to clamp on to and grip the cable 17.

(25) When the gripper block 28b is moved in a direction shown by arrow Z in FIG. 3A, clamp members 46 move away from the wedge bearing members 42. The reaction force acting against the clamp members 46 by the bearing members 42 is reduced. The inner surfaces of the clamp members 44 are moved away from the cable 17. The cable is free to move within the clamp members 46 and the gripper assembly 14.

(26) FIG. 3C shows a hydraulic cylinder 45 connected at one end to the base section of the gripper block 28b and to gripper slider 44 at the other end. The gripper slider 44 is configured to be moved between a cable engaged position as shown in FIG. 3B and a cable release position as shown in FIG. 4A.

(27) In the cable engaged position as shown in FIG. 3B the gripper slider is located in the gripper block 28b between the bearing members 42. The clamp members 46 are moved toward one another to engage the cable in the longitudinal semi-cylindrical grooves 46b.

(28) In the cable release position as shown in FIG. 4A the gripper slider 44 is located partially outside the gripper block 28b. The clamp members 46 are moved away from one another to allow the cable to be removed from the longitudinal semi-cylindrical grooves 46b.

(29) FIG. 4A to 4C presents the gripper assembly during stages of socket passing in cross-sectional view and perspective views with a wall of the gripper assembly removed for clarity.

(30) The hydraulic cylinder 45 (shown in FIG. 3C) is actuated to move the gripper slider 44 from a cable engaged position to a cable release position as shown in FIG. 4A. The gripper slider 44 is located partially outside the gripper block 28b. The clamp members 46 are moved away from one another to allow the cable to be removed from the longitudinal semi-cylindrical grooves 46b.

(31) The gripper assembly comprises guide rails 30. Each guide rail 30 comprises a first part 30a which positions the gripper block 28b at an operative position in which the gripper block is in the pathway of the cable connector at an elevated position above the base 24a of the gripper assembly 14. Each guide rail 30 comprises a second part 30b provides a sloped guide path; and a third part 30c which positions the gripper block 28b at an inoperative position in which the gripper block is not in the pathway of a cable connector and is close to the base 24a of the gripper assembly 14.

(32) Upper guide rails 31 are located above the first part 30a of guide rail 30 and partially along second part 30b to ensure that the gripper block 28b is accurately positioned in the operative position.

(33) The operative position of the gripper block 28b may be defined as the position that the gripper block 28b is located during normal winching of the cable by the gripper assembly 14. The inoperative position of the gripper block 28b may be defined as the position wherein the gripper block 28b is located at the third part 30c of guide rail 30 out of the pathway of the socket 19 to allow socket 19 to pass through the gripper assembly 14.

(34) The operative position of the lid section 28a may be defined as the position that the lid section 28a is located during normal winching of the cable by the gripper assembly 14. The inoperative position of the lid section 28a may be defined as the position wherein the lid section 28a is moved to an open position.

(35) Guide rails 30 are configured to receive wheels which are connected to the base section of the gripper block 28b as shown in FIG. 4A. Hydraulic cylinders 32 and 33 are actuated to pull the gripper block 28b along guide rails 30. This action lowers the gripper block away from the lid section. The hydraulic cylinders 32 and 33 are configured to position the gripper block at the third part 30c of guide rail 30 when the cylinders are at their fully retracted position as shown in FIG. 4B. At this lower position the gripper block 28b is moved out of the pathway of the socket 19.

(36) Hydraulic cylinder 36 is actuated to pivot the lid section 28a between a closed position and an open position. FIG. 4C shows the gripper assembly 14 in a socket pass position. In the socket pass position the gripper block 28b is located at the third part 30c of guide rail and the lid section 28a is pivoted to an open position. The gripper block 28b and lid section 28a have been moved out of the pathway of the cable socket 19. The socket now has sufficient clearance to pass though the gripper assembly 14.

(37) Although this example describes the gripper block being moved vertically out of the pathway of the cable connector. It will be clear that alternatively the gripper block may be moved in laterally, horizontally and/or vertically out of the pathway of the cable connector.

(38) FIGS. 5A and 5B shows perspective views of the linear winch with the gripper assembly 14 in an inoperative socket pass configuration to provide details on the movement of the socket through the gripper assembly 14. The hydraulic cylinder 18 is actuated to a retracted position to move the gripper assembly 14 in a direction shown as arrow Z in FIG. 5A to move the gripper assembly around the socket 19. The socket 19 is able to pass through the slot 26 in the gripper assembly 14. The inoperative state of the gripper assembly provides clearance for the socket 19. The retraction of hydraulic cylinder 18 moves the gripper assembly 14 such that the socket is positioned within the gripper assembly 14. In order to fully pass the socket through the gripper assembly 14 the cable and socket is pulled by the second gripper assembly 16.

(39) Hydraulic cylinder 20 is actuated to an extended position to move the gripper assembly 16 in a direction shown as arrow Y in FIG. 5B. The cable 17 and socket 19 are pulled through the gripper assembly 14 in the inoperative state.

(40) Hydraulic cylinder 18 may be dimensioned such that its stroke length is sufficient to move the gripper assembly 14 around the socket 19 so that the socket completely passed through the gripper assembly 14.

(41) FIGS. 6A to 6D show perspective views of the linear winch to provide details on how the gripper assembly 14 reverts to an operative state after passage of the socket through the gripper assembly 14.

(42) FIG. 6A shows the gripper block 28b located in an inoperative position where the gripper block 28b is located at the third part 30c of guide rail 30. Hydraulic cylinder 36 is actuated to a retracted position to rotate the rod 34 and pivot the lid section 28a from a generally vertical open position to a generally closed horizontal position. The lid section 28a in the closed position is supported by tabs 71 on wall 24e of the gripper assembly housing 24. Although in FIG. 6A wall 24e is removed for clarity, the location of tabs 71 is shown.

(43) Hydraulic cylinders 32 and 33 are actuated to push the gripper block 28b along guide rails 30 from the third part 30c along the second part 30b to a first part 30a which positions the gripper block 28b at an operative position which is parallel with the longitudinal axis of in the housing 12 at an elevated position above the base 24a of the gripper assembly 14.

(44) As the gripper block 28b is moved from an inoperative position to an operative position the gripper slider 44 is located in the cable release position where the gripper slider 44 is located partially outside the gripper block 28b. The clamp members 46 are spaced apart from one another to allow the clamp members 46 to be positioned around cable 17 such that the cable 17 is located within the longitudinal semi-cylindrical groove 46b.

(45) In this operative position shown in FIG. 6B, the upper part of the gripper block 28b is surrounded by the lid section. The lid is in an unlocked position.

(46) The hydraulic cylinder 45 is actuated to move the gripper slider 44 from a cable released position to a cable engaged position where the gripper slider 44 is positioned between the bearing members 42 as shown in FIG. 6B. The clamp members are moved toward one another to engage the cable in the longitudinal semi-cylindrical grooves 46b.

(47) FIG. 6D shows the actuation of hydraulic cylinders 21 and 23 in a general direction Y along the longitudinal axis of the housing 12 to move the lid section 28a from an unlocked position to a locked position. In the unlocked position the wedged shape lid section 28a is positioned on top of the corresponding wedged shape gripper block 28b. The inner surfaces of the wedged shape lid section 28a do not bear against the outer surfaces of the wedged shape gripper block 28b.

(48) The actuation of hydraulic cylinders 21 and 23 in a general direction Y moves the lid section 28b to a locked position such that the inner surfaces of the wedged shape lid section 28a bears against the outer surfaces of the wedged shape gripper block 28b. In this locked position the lid is clamped onto the gripper block 28b. In the locked position the lid provides structural support to the gripper block and may facilitate the gripper block to direct its clamping force to the cable.

(49) FIG. 6D shows the gripper assembly in an operative position where actuation of the hydraulic cylinder 18 to move the gripper assembly 14 in a direction shown by arrow Y results in the gripper assembly 14 gripping the cable and moving the cable in a direction Y. If the hydraulic cylinder 18 moves the gripper assembly 14 in a direction shown by arrow Z the gripper assembly in an operative position direction Y allows the cable to move freely within the gripper assembly.

(50) The gripper assembly 14 is operable to move between an operative position and inoperative position. In the operative position the gripper assembly is configured to grip and release the cable. In the inoperative position the gripper assembly is configured to be moved out of the pathway of the cable socket.

(51) In order to pass the socket 19 through the gripper assembly 14, the gripper block 28b releases the cable and moves to an inoperative position to provide a pathway for the socket 19 to pass through the gripper assembly 14. When the gripper assembly 14 is positioned in the inoperative position, the gripper assembly 16 is positioned in an operative position to grip, hold, pull and/or push the cable. The gripper assembly 16 is configured to maintain the tension of the cable when the gripper assembly 14 is positioned in an inoperative position. The gripper assembly 16 is configured to moves the cable along the longitudinal axis of the winch assembly to facilitates the passing of the socket 19 through the gripper assembly 14.

(52) The actions of passing the socket 19 through the gripper assembly 16 are the same as the above described method of passing the socket through the gripper assembly 14. The gripper assembly 14 is maintained in an operative position during the passing of the socket through the gripper assembly 16 to hold, pull and/or push the cable. The gripper assembly 14 is configured to maintain the tension of the cable 17 when the gripper block of the gripper assembly 16 is positioned in an inoperative position to allow the socket to pass. The gripper assembly 14 is configured to move the cable 17 along the longitudinal axis of the winch assembly which facilitates the passing of the socket 19 through the gripper assembly 16.

(53) Although this example describes two gripper assemblies 14 and 16 in the winch to pull the cable 17, additional gripper assemblies may be used in combination to provide additional pulling and/or pushing force when winching heavy loads.

(54) Although this example describes a single hydraulic cylinders connected to each of the gripper assemblies 14 and 16, additional hydraulic cylinders may be connected between the housing 12 and each gripper assembly which may be used in combination with the hydraulic cylinders 18 and 20 to provide additional pulling and/or pushing force when winching heavy loads.

(55) Although, this example shows the lid section 28a being pivoted to an open position before the socket is able to pass through the gripper assembly 14, it will be clear that the gripper block 28b and the lid section 28a may be dimensioned or arranged such that the socket may pass through the gripper assembly when the lid section 28a is in a closed position and the gripper block 28b is in an inoperative position.

(56) Throughout the specification, unless the context demands otherwise, the terms comprise or include, or variations such as comprises or comprising, includes or including will be understood to imply the inclusion of a stated integer or group of integers, but not the exclusion of any other integer or group of integers. Furthermore, relative terms such as, horizontal, vertical, raise, lower and the like are used herein to indicate directions and locations as they apply to the appended drawings and will not be construed as limiting the invention and features thereof to particular arrangements or orientations.

(57) The foregoing description of the invention has been presented for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise form disclosed. The described embodiments were chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilise the invention in various embodiments and with various modifications as are suited to the particular use contemplated. Therefore, further modifications or improvements may be incorporated without departing from the scope of the invention as defined by the appended claims.

(58) The invention provides a linear winch assembly, gripper assembly and a method of use. The linear winch assembly comprises a first gripper assembly comprising a first gripper block operable to grip a cable and a second gripper assembly comprising a second gripper block operable to grip a cable. The winch assembly comprises a first mechanism operable to move at least part of the first gripper block out of the pathway of a cable connector to allow the connector to pass through the first gripper assembly. The winch assembly also comprises a second mechanism operable to move at least part of the second gripper block out of the pathway of a cable connector to allow the connector to pass through the second gripper assembly

(59) The sequential passing of the cable connector through each gripper assembly allows the winch assembly to maintain the cable tension. The first gripper assembly may be moved to an inoperative position out of the pathway of the socket while the second assembly maintains the cable tension and applied a pulling force to the cable. The second gripper assembly may subsequently be moved to an inoperative position out of the pathway of the cable connector while the first gripper assembly maintains the cable tension and applied a pulling force to the cable.

(60) The linear winch assembly is able to perform tasks involving pulling in or paying out long cables with cable socket connections. The assembly is capable of passing the cable connector while maintaining cable tension from heavy loads.

(61) Another benefit of the improved gripper assembly is that it may improve the performance of the winch assembly by facilitating the passage of a cable connector quickly and safely through the gripper assembly without having to use a crane or lifting equipment.

(62) Various modifications to the above described embodiments may be made within the scope of the invention herein intended.
