Technical Field

[0001] This utility model relates to the field of cable support technology, specifically an adjustable cable support for power supply in mines. Background Technology

[0002] During construction in mining areas, cables need to be laid for mining equipment. However, the complex terrain of mining areas necessitates the use of cable supports for installation. But existing mining cable supports have many problems or defects:

[0003] Currently, during cable installation, a support column of appropriate length is typically rotated according to the installation environment, and the support height is adjusted by the depth of insertion into the ground. However, this method is not convenient for adjusting the horizontal installation position of the cable and is not flexible enough.

[0004] Based on this, this solution proposes an adjustable cable support for mine power supply. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable cable support for power supply in mines, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable cable support for mine power supply, including a fixing block.

[0007] The bottom of the fixed block is fixedly installed with a support base, and two first lead screws are rotatably installed inside the fixed block. Each of the two first lead screws is fixedly sleeved with a worm gear, and the top of the two first lead screws is threaded with the same movable rod. Two worms with worm gears meshing simultaneously are rotatably installed inside the fixed block.

[0008] A mounting rod is fixedly installed on the top of the movable rod. Two second lead screws are rotatably installed inside the mounting rod. The same gear is fixedly sleeved between the two second lead screws, and the other ends of the two second lead screws, which are far apart from each other, are fixedly sleeved with lead screw guide sleeves. Mounting plates are fixedly installed on the two lead screw guide sleeves. Fixing rods are fixedly installed on both sides of the top of the two mounting plates. A locking bolt is threaded on any one of the fixing rods, and a cable clamping plate is rotatably installed on one end of any one of the locking bolts.

[0009] A metal rod is fixedly installed inside the movable rod, and a movable hole is opened at the front end of the movable rod. A through hole is opened on the metal rod, and a vertical rod is movably installed in the through hole. A connecting rod and a rack are fixedly installed at both ends of the vertical rod, respectively. The rack meshes with a gear, and one end of the connecting rod extends out of the movable hole.

[0010] Preferably, a crank handle is fixedly sleeved at one end of the worm gear.

[0011] The above technical solution is adopted, using a crank handle.

[0012] Preferably, telescopic rods are fixedly installed between both mounting plates and the fixing block.

[0013] By adopting the above technical solution, the rotation of the mounting plate is restricted by the telescopic rod.

[0014] Preferably, two slide rails are fixedly installed inside the fixed block, and sliders are slidably installed on both slide rails. Both sliders are fixedly connected to the movable rod.

[0015] The above technical solution facilitates the movement of the movable rod through the slide rail and slider.

[0016] Preferably, a limit bolt is threaded onto the connecting rod, and a long bar is fixedly installed at the front end of the movable rod. The long bar has multiple limit grooves that are adapted to the limit bolts and are evenly spaced along the vertical direction.

[0017] By using the above technical solution, the position of the connecting rod can be locked and fixed by tightening the rotating limiting bolt inward, so that the limiting bolt is locked into the limiting groove on the long rod, and the horizontal position of the two mounting plates and the two cables can be locked and fixed.

[0018] Preferably, a return spring is sleeved on the vertical rod, with one end of the return spring fixed to the vertical rod and the other end fixed to the inner wall of the through hole.

[0019] By adopting the above technical solution, the return spring facilitates the reset of the vertical rod.

[0020] Preferably, the threads of the two second lead screws are arranged in opposite directions.

[0021] By adopting the above technical solution and through the above settings, the two mounting plates can be moved in opposite directions.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: By placing the cables between two corresponding cable clamps and then tightening the locking bolts on both sides, the locking bolts push the corresponding cable clamps to move horizontally, thereby causing the two cable clamps on the same side to move towards each other, thus clamping and fixing the two cables. By turning the crank, the worm gear rotates, which in turn drives the two worm wheels to rotate, which in turn drives the two first lead screws to rotate. The two first lead screws can adjust the height of the movable rod, thereby adjusting the height of the two mounting plates, thus enabling the... The installation height of the two cables is adjusted. Then, pulling down the connecting rod moves the rack downwards, which in turn rotates the gear, causing the two second lead screws to rotate. These second lead screws then move the two mounting plates left and right, thus moving the two cables left and right. This allows for adjustment of the horizontal installation position of the two cables. Finally, by tightening the rotating limit bolts inwards, the limit bolts engage with the limit grooves on the long rod, locking the position of the connecting rod and thus securing the horizontal position of the two mounting plates and the two cables. This utility model has a simple structure and is easy to use. The adjustable cable bracket for mine power supply facilitates quick and easy adjustment of the horizontal installation position and height of the cables, offering flexibility and convenience for mine power supply applications.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution: an adjustable cable bracket for mine power supply, including a fixed block 1, a support base 2 fixedly installed at the bottom of the fixed block 1, and two first lead screws 16 rotatably installed inside the fixed block 1. Each of the two first lead screws 16 is fixedly sleeved with a worm gear 14, and the top ends of the two first lead screws 16 are threadedly sleeved with the same movable rod 4. A worm 15, with the two worm gears 14 meshing simultaneously, is rotatably installed inside the fixed block 1. One end of the worm 15 is fixedly sleeved with a crank handle 3. Two slide rails are fixedly installed inside the fixed block 1, and sliders are slidably installed on each of the two slide rails. Both sliders are fixedly connected to the movable rod 4. An installation rod 7 is fixedly installed at the top of the movable rod 4. Two second lead screws 18 are rotatably installed inside the installation rod 7. The two second lead screws 18 are fixedly sleeved with the same gear 23, and the other ends of the two second lead screws 18, which are far apart from each other, are fixedly sleeved with lead screw guide sleeves 20. The thread directions of the two second lead screws 18 are opposite. Each lead screw guide sleeve 20 is fixedly mounted with an installation plate 5. Fixing rods 13 are fixedly mounted on both sides of the top of each of the two installation plates 5. A locking bolt 12 is threaded onto each fixing rod 13. A cable clamping plate 6 is rotatably mounted on one end of each locking bolt 12. With this structure, by placing the cables between the corresponding two cable clamps 6 and then tightening the locking bolts 12 on both sides, the locking bolts 12 push the corresponding cable clamps 6 to move horizontally, thus causing the two cable clamps 6 on the same side to move towards each other, thereby clamping and fixing the two cables. Turning the crank handle 3 drives the worm gear 15 to rotate, which in turn drives the two worm wheels 14 to rotate, which in turn drives the two first lead screws 16 to rotate. The two first lead screws 16 can adjust the height of the movable rod 4, thereby adjusting the height of the two installation plates 5 and thus adjusting the installation height of the two cables.

[0030] Combination Figure 1-4As shown, a metal rod 22 is fixedly installed inside the movable rod 4, and a movable hole is opened at the front end of the movable rod 4. A through hole is opened on the metal rod 22, and a vertical rod 21 is movably installed in the through hole. A connecting rod 8 and a rack 17 are fixedly installed at both ends of the vertical rod 21, respectively. A return spring 19 is sleeved on the vertical rod 21. One end of the return spring 19 is fixed to the vertical rod 21, and the other end of the return spring 19 is fixed to the inner wall of the through hole. The rack 17 meshes with the gear 23. One end of the connecting rod 8 extends to the outside of the movable hole. Telescopic rods 24 are fixedly installed between the two mounting plates 5 and the fixed block 1. With the above structural settings, pulling down the connecting rod 8 drives the rack 17 to move downward. The rack 17 drives the gear 23 to rotate, which in turn drives the two second lead screws 18 to rotate. The two second lead screws 18 drive the two mounting plates 5 to move left and right separately, which in turn drives the two cables to move left and right separately, thereby adjusting the horizontal installation position of the two cables.

[0031] Combination Figure 1-4 As shown, a limiting bolt 11 is threaded onto the connecting rod 8, and a long rod 9 is fixedly installed at the front end of the movable rod 4. Multiple limiting grooves 10 that are adapted to the limiting bolt 11 are equally spaced along the vertical direction on the long rod 9. With the above structural setting, by rotating the limiting bolt 11 inward to lock it in, the limiting bolt 11 is locked into the limiting groove 10 on the long rod 9, thereby locking and fixing the position of the connecting rod 8, and thus locking and fixing the horizontal position of the two mounting plates 5 and the two cables.

[0032] The working principle of this utility model is as follows: By placing the cables between two corresponding cable clamps 6, and then tightening the locking bolts 12 on both sides, the locking bolts 12 push the corresponding cable clamps 6 to move horizontally, thereby causing the two cable clamps 6 on the same side to move towards each other, thus clamping and fixing the two cables. By turning the crank handle 3, the worm gear 15 is rotated, which in turn drives the two worm wheels 14 to rotate, which in turn drives the two first lead screws 16 to rotate. The two first lead screws 16 can adjust the height of the movable rod 4, thereby adjusting the height of the two mounting plates 5, thus securing the two cables. The installation height is adjusted, and then pulling down the connecting rod 8 moves the rack 17 downwards. The rack 17 drives the gear 23 to rotate, which in turn drives the two second lead screws 18 to rotate. The two second lead screws 18 drive the two mounting plates 5 to move left and right separately, which in turn drives the two cables to move left and right separately. This allows adjustment of the horizontal installation position of the two cables. Then, by tightening the rotating limiting bolt 11 inwards, the limiting bolt 11 is locked into the limiting groove 10 on the long rod 9, thus locking and fixing the position of the connecting rod 8, and thus locking and fixing the horizontal position of the two mounting plates 5 and the two cables. This utility model has a simple structure and is easy to use. The adjustable cable bracket for mine power supply allows for quick adjustment of the horizontal installation position and installation height of the cables, making it flexible and convenient for use in mine power supply.
