Description

Technical Field

[0001] The present invention relates to the field of cable storage, and in particular to a cable storage device for a mobile camera in an underground coal mine. Background Art

[0002] With the popularization of surveillance cameras in underground mine tunnels, "no video, no work" has become a prerequisite for safe production. Therefore, it is necessary to install cameras at various locations in the underground tunnels to monitor the work situation and upload it to the ground dispatching and command center. Due to the change of work location, underground cameras need to be moved frequently. However, due to the complex underground environment of coal mines, the management of cables during the movement of cameras has become an important issue, so the cables need to be stored centrally.

[0003] Common cable storage devices for mobile cameras in underground coal mines only include the function of cable storage. They can fix the cables to the surrounding anchor rods or meshes through cable ties or wires, but lack the functions of cable reeling and anti-rotation. The performance of the cables during storage cannot be guaranteed. The cables are easily fixed to the surrounding anchor rods or meshes through cable ties or wires, which causes the cables to become entangled or knotted. The rotation of the reel will cause the cables to become loose and outward, affecting the cable performance and reeling stability.

[0004] Therefore, in view of the fact that the above-mentioned mobile camera cable storage device for underground coal mines lacks the functions of cable winding and anti-rotation, a mobile camera cable storage device for underground coal mines can be designed. The hand wheel is rotated by the handle, and the hand wheel drives the wire hook to rotate through the winding shaft. The wire hook is pulled by the wire hook to be wound on the winding shaft, and the position of the hand wheel is fixed by inserting the left end of the telescopic limit rod into the limit hole, thereby preventing the winding shaft from rotating and causing the cable to loosen and be released. Summary of the invention

[0005] In order to overcome the common cable storage devices for mobile cameras in coal mines, the functions of cable reeling and anti-rotation are lacking, and the performance of the cables during storage cannot be guaranteed. It is easy for the cables to be fixed to the surrounding anchor rods or meshes through cable ties or wires, which causes the cables to become entangled or knotted. The rotation of the reel roller will cause the cables to become loose and outward, affecting the cable performance and reeling stability.

[0006] The technical solution of the present invention is: a mobile camera cable storage device in a coal mine, comprising a horizontal fixed base; also comprising a winding shaft, a wire hook, a hand wheel, a handle, a limit hole and a telescopic limit rod, the winding shaft is rotatably connected to the center of the left side inside the horizontal fixed base, a wire hook is arranged on the upper left side of the winding shaft, a hand wheel is arranged at the center of the right side of the horizontal fixed base corresponding to the position of the winding shaft, the right end of the winding shaft passes through the horizontal fixed base and is connected with the hand wheel, a handle is arranged on the right side of the hand wheel, a number of limit holes are arranged at equal intervals on the right side of the horizontal fixed base corresponding to the position of the hand wheel, a telescopic limit rod is arranged at the position of the limit hole on the left side of the hand wheel, and the left end of the telescopic limit rod is inserted into the inside of the limit hole.

[0007] Preferably, the protective door is opened by the handle, and then the cable is passed through the cable slot, and the cable is hooked on the wire hook, and then the protective door is closed. After the protective door is closed, the hand wheel is rotated by the handle, and the hand wheel drives the wire hook to rotate through the reel, and the wire hook is pulled to reel in the reel by the wire hook. After the cable is reeled in the reel, the hand wheel continues to be rotated until the hand wheel drives the telescopic limit rod to move to the limit hole, and then the telescopic limit rod is pulled toward the limit hole until the left end of the telescopic limit rod is inserted into the inside of the limit hole, so as to fix the position of the hand wheel. The cable storage device for mobile cameras in coal mines only includes the function of cable storage, and can fix the cable to the surrounding anchor rods or meshes by cable ties or wires, but lacks the function of cable reeling and anti-rotation, and cannot guarantee the performance of the cable during storage. It is easy for the cable to be fixed to the surrounding anchor rods or meshes by cable ties or wires, so the cable will be entangled or knotted, and the rotation of the reel will cause the cable to be loose and released, affecting the cable performance and reeling stability.

[0008] Preferably, the front side of the horizontal fixed base is movably connected to a protective door via a hinge, a handle is provided at the left end of the front side of the protective door, and a wire entry slot is provided at the center of the front side of the protective door.

[0014] Preferably, two clamping grooves are symmetrically provided on the front and rear sides of the catheter body, and two fixing strips are symmetrically provided on the left and right ends of the front and rear sides of the catheter body corresponding to the positions of the clamping grooves.

[0016] Preferably, two locking links are symmetrically rotatably connected to the left and right sides of the upper guide rod, and the two locking links are rotatably connected to the two clamping claws respectively.

[0017] Beneficial effects of the present invention: 1. Open the protective door through the handle, then pass the cable through the cable slot, hook the cable on the hook, and then close the protective door. After the protective door is closed, turn the hand wheel through the handle, and the hand wheel drives the hook to rotate through the reel, and pull the hooked cable on it through the hook to reel it on the reel, so as to solve the common coal mine underground mobile camera cable storage device, which only includes the function of cable storage, and can fix the cable to the surrounding anchor rods or mesh by cable ties or wires, but lacks the function of cable reeling, and cannot guarantee the performance of the cable during storage. It is easy for the cable to be fixed to the surrounding anchor rods or meshes by cable ties or wires, so that the cable is entangled or knotted, affecting the performance of the cable; 2. After the cable is wound on the winding shaft, continue to turn the hand wheel until the hand wheel drives the telescopic limit rod to move to the limit hole, and then pull the telescopic limit rod toward the limit hole until the left end of the telescopic limit rod is inserted into the limit hole, thereby fixing the position of the hand wheel, thereby preventing the winding shaft from rotating and causing the cable to loosen and release outside, so as to solve the common coal mine underground mobile camera cable storage device, which only includes the function of cable storage. The cable can be fixed to the surrounding anchor rods or mesh by cable ties or wires, but lacks the anti-rotation function and cannot ensure the stability of the cable when it is wound. The winding roller is prone to rotate, which will cause the cable to loosen and release outside, affecting the winding stability. BRIEF DESCRIPTION OF THE DRAWINGS
