DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] According to the embodiment of the present invention, the underground cable hanging device of the underground coal mine comprises a fixing plate 1, a positioning member 3 and a clamping member 8. The fixing plate 1 is used to be connected to the mine wall. A plurality of mounting positions 2 are arranged on the fixing plate 1 along a first direction. Each positioning member 3 is detachably connected to the fixing plate 1 corresponding to one mounting position 2. The first end of the positioning member 3 is provided with a first sliding hole. The first support rod 5 slides in the first sliding hole. The first end of the clamping member 8 is connected to an end of at least one first support rod 5 away from the fixing plate 1 to correspond to one mounting position 2. The second end of the clamping member 8 is provided with a limit hook. The limit hook is used to constrain the cable. The opening direction of the limit hook faces the positioning member 3. The fixing plate 1 is fixedly connected to the mine wall. The positioning member 3 selects mounting positions 2 of different heights according to the height of the cable. The clamping member 8 is connected to the positioning member 3. The clamping member 8 clamps and fixes the cable through the limit hook. The positioning member 3 is a cylindrical hollow cylinder with an opening at one end and a closed end at the other end. Each mounting position 2 of the fixing plate 1 is provided with a hole groove, and the hole groove is used to accommodate the positioning member 3 .

[0025] The underground coal mine cable hanging device according to the embodiment of the present invention has the advantages of good clamping effect and adaptability to cables of different heights.

[0026] In some embodiments, the first support rod 5 slides in the first sliding hole along the extension direction of the positioning member 3, and the first sliding hole includes a small diameter section and a large diameter section in sequence in the direction from the first end to the second end of the positioning member 3.

[0027] Specifically, the first support rod 5 slides in the first sliding hole of the positioning member 3 so that the clamping member 8 can move within a certain range relative to the fixing plate 1 to meet the clamping needs of cables of different sizes. The small diameter section and the large diameter section of the first sliding hole form a sliding channel for the first support rod 5, and the aperture of the small diameter section is larger than the diameter of the first support rod 5. It can be understood that the thickness of the first support rod 5 is fixed as a straight rod.

[0028] In some embodiments, the first end of the first support rod 5 is connected to the clamping member 8, the second end of the first support rod 5 is connected to the first top plate 6, a first spring 7 is disposed outside the first support rod 5, one end of the first spring 7 is abutted against the first top plate 6, and the other end of the first spring 7 is abutted against the inner wall of the positioning member 3.

[0029] Specifically, the first support rod 5 is limited by the first top plate 6. As the first top plate 6 moves in the large diameter section of the first sliding hole, the first support rod 5 can extend and retract relative to the positioning member 3 to drive the clamping member 8 to move relative to the fixed plate 1. The first spring 7 is sleeved on the first support rod 5 and can push the first top plate 6 to drive the first support rod 5 to retract into the positioning member 3, thereby achieving automatic resetting of the clamping member 8 and facilitating clamping of the cable.

[0030] In some embodiments, the diameter of the first top plate 6 is adapted to the aperture of the large diameter section, and the diameter of the first support rod 5 is adapted to the aperture of the small diameter section.

[0031] Specifically, the diameter of the first top plate 6 at the second end of the first support rod 5 is larger than the aperture of the small diameter section and smaller than the aperture of the large diameter section. The first top plate 6 only slides in the large diameter section and cannot enter the small diameter section. When the user pulls the clamping member 8, the clamping member 8 drives the first support rod 5 and the first top plate 6 to move away from the fixed plate 1, and the first top plate 6 compresses the first spring 7. When the user releases the clamping member 8, the first spring 7 resets and pushes the first top plate 6 to drive the first support rod 5 and the clamping member 8 to reset and clamp the cable.

[0032] In some embodiments, the limiting hook includes a clamping plate 12 and a second support rod 9 , the first end of the second support rod 9 enters the clamping member 8 and is slidably connected to the clamping member 8 , and the second end of the second support rod 9 is connected to the clamping plate 12 .

[0033] Specifically, the clamping plate 12 of the limit hook cooperates with the clamping member 8 to form a clamping groove. The clamping plate 12 is an L-shaped block, and the clamping member 8 is a rectangular block. The clamping plate 12 and the clamping member 8 are fitted to form a clamping groove, which can limit the cable from moving down and out of the clamping range of the clamping member 8. The clamping plate 12 increases the size of the clamping space between the clamping member 8 and the fixed plate 1, and can clamp more cables. The second support rod 9 is used to movably connect the clamping plate 12 to the clamping member 8.

[0034] In some embodiments, the first end of the second support rod 9 is connected to the second top plate 10, and a second spring 11 is disposed outside the second support rod 9. One end of the second spring 11 abuts against the second top plate 10, and the other end of the second spring 11 abuts against the inner wall of the clamping member 8.

[0035] Specifically, the second top plate 10 is located in the second sliding hole of the clamping member 8, and the second sliding hole also has a large diameter section and a small diameter section. The second top plate 10 slides in the large diameter section to limit the second support rod 9. The second spring 11 is used to drive the second support rod 9 to realize automatic resetting of the second support rod 9.

[0036] In some embodiments, the positioning member 3 also includes a first tightening bolt 16 and a second tightening bolt 17. The first tightening bolt 16 passes through the positioning member 3 and abuts against the first support rod 5. The first tightening bolt 16 is threadedly connected to the positioning member 3, and the second tightening bolt 17 passes through the clamping member 8 and abuts against the second support rod 9.

[0037] Specifically, the first tightening bolt 16 passes through the positioning member 3 and enters the small diameter section of the first sliding hole. The first top bolt is threadedly connected to the positioning member 3. After the first tightening bolt 16 enters the first sliding hole, it presses against the first support rod 5 to prevent the first support rod 5 from moving. The second tightening bolt 17 passes through the clamping member 8 and is threadedly connected to the clamping member 8. The second top bolt abuts against the second support rod 9 to fix the first end of the second support rod 9, which can lock the second support rod 9 to prevent it from sliding in the clamping member 8.

[0038] In some embodiments, the clamping member 8 also includes a first anti-slip pad 18 and a second anti-slip pad 19. The first anti-slip pad 18 is located at the second end of the clamping member 8, and the second anti-slip pad 19 is located on the side of the limiting hook adjacent to the clamping member 8. At least part of the first anti-slip pad 18 and the second anti-slip pad 19 are arranged opposite to each other.

[0039] Specifically, the first anti-skid pad 18 and the second anti-skid pad 19 are respectively arranged on the groove walls on both sides of the clamping groove, and the anti-skid pads can increase the friction force to prevent the clamped cable from moving. The areas of the first anti-skid pad 18 and the second anti-skid pad 19 can be different. The first anti-skid pad 18 and the first support rod 5 are located at both ends of the same side of the clamping member 8. The second anti-skid pad 19 is located on the side of the limit hook adjacent to the clamping member 8 to increase the friction force of the clamping groove and prevent the cable from moving in the clamping groove.

[0040] In some embodiments, mounting plates 13 are disposed at both ends of the fixing plate 1 , the mounting plates 13 are symmetrically arranged with respect to the fixing plate 1 , and mounting holes 14 are disposed on the mounting plates 13 .

[0041] Specifically, mounting plates 13 are provided at both ends of the fixing plate 1, and the mounting plates 13 are fixedly connected to the fixing plate 1. The mounting plates 13 are provided at the ends of the fixing plate 1 and are symmetrically arranged about the fixing plate 1 to ensure that the fixing plate 1 is firmly connected to the mine wall. Mounting holes 14 are provided on the mounting plates 13, and the mounting plates 13 and the mounting holes 14 can be docked with external bolts and the fixing structure on the mine wall, thereby facilitating the installation of the fixing plate 1 and the corresponding hook structure.

[0042] In some embodiments, the underground cable hanging device of the coal mine further includes a fastening bolt 4 , which passes through the fixing plate 1 and is connected to the positioning member 3 to fix the positioning member 3 .

[0043] Specifically, the fastening bolt 4 is threadedly connected with the fixing plate 1 and the positioning member 3. The fastening bolt 4 fixes the positioning member 3 to the fixing plate 1 to prevent the fixing member from moving relative to the fixing plate 1. A gasket 15 is sleeved on the fastening bolt 4. The gasket 15 can increase the contact area between the fastening bolt 4 and the fixing plate 1, thereby increasing the fastening effect of the fastening bolt 4 on the positioning member 3.
