DETAILED DESCRIPTION

[0026] In the following detailed description, reference is made to the accompanying drawings and photographs that form a part hereof, and in which is shown by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and like numerals represent like details in the various figures. Also, it is to be understood that other embodiments may be utilized and that process or other changes may be made without departing from the scope of the disclosure. The following detailed description is not to be taken in a limiting sense, and the scope of the invention is defined only by the appended claims and their equivalents. In accordance with the disclosure, a hanger for use with a water line in an underground mine is hereinafter described.

[0027] Reference is now made to FIGS. 1-12, which illustrate various hangers that may be used with a water line in underground mining operations. With respect to FIG. 12, a representative channel 10 that is typically mounted within an underground mine is shown. The channel 10 includes multiple rollers 20 mounted thereon. A pair of belt hangers with drop-down chains 30 extend from the roof (R) of the mine. Roof bolts (not shown) are positioned within holes drilled in the roof (R) of the mine, such that the belt hangers are supported by the roof bolts.

[0028] Instead of inserting additional holes into the roof (R) of the mine for additional belt hangers with chains to support a water line 420 (independent of the support), one or more of the hangers shown in FIGS. 1-11 may be utilized. The lower hanger 40 illustrated in FIG. 1 includes a rounded or J-shaped body 50. As specifically shown in FIG. 1, the J-shaped body is connected to a substantially vertical body portion 60. The vertical body portion 60 has an aperture 70 cut through it near the top edge 80 of the vertical body portion 60. A fastener (not shown) may be used to connect/secure the lower hanger to the channel. Either a fresh water line or discharge water line may sit within J-shaped body 50, which holds and supports the line. The hanger 40 is typically made of a rigid material, such as a metal, i.e., steel. It should be appreciated that multiple hangers may be used to fully support and hold a water line 20. The water line 20 may between two and eight inches in thickness and is often made of aluminum or PVC pipe. It should be appreciated that the hangers may come in different sizes to accommodate different sizes of water lines.

[0029] Turning to FIGS. 2 and 3, another lower hanger 90 is illustrated. The lower hanger 90 includes a J-shaped body 100 connected to an intermediate piece 110, which is slightly angled. The intermediate piece 110 is connected to a substantially vertical portion 120, which in turn is connected to a hanger portion 130 that is configured to engage with the channel 10. Specifically, the hanger portion 130 includes a tab 140 extending in a direction substantially parallel to the vertical portion 120. The hanger 90 is typically made of a rigid material, such as a metal, i.e., steel. The underside of the hanger portion 130 is slightly rounded into the tab 140 to form a better fit around the channel. Either a fresh water line or discharge water line may sit within J-shaped body 100. Advantageously, this hanger 90 may be used without any additional fasteners, i.e., the tab 140 engages directly with the channel. Specifically, the hanger portion 130 extends over the top of the channel such that the tab 140 “hooks” on the top of the channel to secure the hanger firmly in place. When the water line is placed within the body, the tab 140 more firmly engages with the channel such that it is essentially “locked” into place.

[0030] With reference to FIGS. 4-6, a lower hanger 150 is illustrated. The hanger 150 is typically made of a rigid material, such as a metal, i.e., steel. The lower hanger 150 includes a J-shaped body 160. An elastomeric pad 170 may be positioned within the J-shaped body 160 to directly contact the water line, such that there is not a rigid material to rigid material connection between the hanger 150 and the water line. Either a fresh water line or discharge water line may sit within J-shaped body 100. The J-shaped body 160 is connected to an intermediate piece 180, which is slightly angled. The intermediate piece 180 is connected to a substantially vertical portion 190, which in turn is connected to a hanger portion 200 via a slightly curved portion 210. that is configured to engage with the channel 10. The substantially vertical portion 190 has an elongated slot 220 positioned through its front face.

[0031] The hanger portion 200 includes a tab 230 extending in a direction substantially perpendicular to the vertical portion 190. A keyhole-shaped hole 240 is cut into the tab 230 such that its distal end is separated into two ends 250, 260. These ends 250, 260 are flared upward at approximately a forty-five degree (45°) angle. Specifically, the hanger portion 200 extends over the top of the channel such that the tab 230 hangs on the top of the channel to secure the hanger 150 firmly in place. As shown in FIG. 6, a retention fastener 270 extends between the two ends 250, 260 through the hole 240 and an end portion 280 engages with the elongated slot 220 to secure/lock the hanger 150 to the channel.

[0032] With reference to FIGS. 7-9, an upper hanger 290 is illustrated. The upper hanger 290 is typically made of a rigid material, such as a metal, i.e., steel. The lower hanger 290 includes a J-shaped body 300. An elastomeric pad 310 may be positioned within the J-shaped body 300 to directly contact the water line, such that there is not a rigid material to rigid material connection between the hanger 150 and the water line. Either a fresh water line or discharge water line may sit within J-shaped body 300. The J-shaped body 300 is connected to a connector piece 320, that in turn connects to a substantially vertical piece 330. A support 340 connects to the vertical piece 330 and the J-shaped body 300 to provide additional support for holding the line. The support 340 fits within two notches 350, 360 positioned in the vertical piece 330 and extends outward until contacting and supporting the J-shaped body 300. An elongated slot 370 is positioned below the support 340. The vertical piece 330 extends downward until connected to a hanger portion 380. The hanger portion 380 includes a tab 390 extending perpendicular to the vertical piece 330. A keyhole-shaped cutout 400 is in the tab and the tab has a downward-shaped end piece 410. The hanger portion 380 extends over the top of the channel such that the tab 390 hangs on the top of the channel to secure the hanger 390 firmly in place. A retention fastener extends through the cutout 400 and the slot 370 to secure/lock the hanger 290 to the channel.

[0033] Advantageously, the hangers described herein offers a number of advantages. Initially, the hangers may be easily installed on the channel by a single person without the use of any additional tools or drilling within the mine. Because the hangers connect directly to the channel, they occupy minimal space within the mine and is out of the way of fasteners and vibration from the roller of the conveying belt. In addition, the hangers may be used with a fresh water line on a belt conveyor and/or a discharge water line on a belt conveyor. For example, one or more hangers may be used on a first side of the channel for use with a fresh water line on the belt conveyor and one or more additional hangers may be used on a second, opposite side of the channel for use with a discharge water line on the belt conveyor.

[0034] The foregoing descriptions of various embodiments have been presented for purposes of illustration and description. These descriptions are not intended to be exhaustive or to limit the invention to the precise forms disclosed. The embodiments described provide the best illustration of the inventive principles and their practical applications to thereby enable one of ordinary skill in the art to utilize the disclosure in various embodiments and with various modifications as are suited to the particular use contemplated.
