[0002] Underground power supply is an important part of underground workplaces such as coal mines. It involves the stable supply of electricity and safe production. The construction of the underground power supply system requires the use of a large number of wires. In order to protect the cables, it is necessary to use devices such as cable ducts that can accommodate cables. However, in the existing technology, such devices have the following disadvantages. First, the part of the cable located inside the cable duct is often completely fixed with a clamp, which is not convenient for subsequent maintenance and cable reeling when removed. At the same time, the cable cannot obtain space for movement and may be broken due to accidental collision and pulling. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide an underground power supply wire arrangement device which is easy to maintain, and is equipped with a roller wire management mechanism and a redundant section support device, which facilitates the subsequent winding of cables and the wire pulling action during maintenance. When the middle section of the cable breaks, it is also very convenient to connect the cables by pulling the cables on both sides of the break.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: an underground power supply wire arrangement device that is easy to maintain, comprising a first bracket, a plug-in rail is provided on the top of the first bracket, an anchor rod is installed at the bottom of the first bracket, a third roller mounting frame is penetrated through the side of the plug-in rail, one side of the plug-in rail is inserted and connected with the insertion strip on the side of the mounting groove, a top flap is hinged on the top of the mounting groove, a roller wire arrangement mechanism is installed on the inner side of the mounting groove, and the roller wire arrangement mechanism comprises a second bracket, and the first roller mounting frame and the second roller mounting frame are installed on the inner side of the second bracket A roller mounting frame, a first wire roller is installed on the inner side of the first roller mounting frame, a second wire roller is installed on the inner side of the second roller mounting frame, a first support plate is provided on the top of the second bracket, a second support plate is provided on the top of the second roller mounting frame, a screw is rotatably installed on the side of the second support plate, one end of the screw passes through the first support plate and is threadedly connected thereto, metal bellows screw seats are provided at both ends of the mounting groove, metal bellows are connected between two adjacent groups of mounting grooves via metal bellows screw seats, and a redundant segment support device is installed on the inner side of the mounting groove.

[0005] The beneficial effects of the utility model are as follows: when the device is installed, the insert strip on the side of the installation groove is inserted into the insertion track, and the locking bolt is used to pass through the through groove to lock the installation groove and the insertion track, and then the first bracket can be fixed on the tunnel ground through the anchor rod, and the two adjacent groups of installation grooves are connected to the metal corrugated cover through the metal corrugated cover screw seat, so that the installation groove can adapt to the turning and undulating terrain in the winding tunnel without affecting the protection of the cables.

[0006] When laying the cable, the knob is turned according to the diameter of the cable to drive the screw to rotate, and the spiral transmission between the screw and the first support plate drives the first support plate together with the second roller mounting frame to adjust the position under the telescopic cooperation of the telescopic rod, so as to adjust the spacing between the first wire roller and the second wire roller, and adjust the position of the third wire roller by sliding the slider so that the gap between the third wire roller and the first wire roller and the second wire roller is aligned, and then tighten the locking bolt used to lock the adjusting slide rail and the slider, so that the cable can be introduced from one end of the mounting groove through the gap between the first wire roller and the second wire roller, and bypass the third wire roller, so that one end of the cable The first end is led out from the other end of the installation groove, passes through the metal corrugated cover and continues to be led into the next group of installation grooves, until it passes through one end of the last group of installation grooves, thus completing the wiring of the line. Through multiple sets of independently arranged roller cable management mechanisms, multiple cables can be arranged separately without being entangled with each other. Moreover, since the first wire roller and the second wire roller limit the clamping of the cables, the movement of the cables is not affected, that is, the cables can be freely pulled through the gap between the rotatable first wire roller and the second wire roller, which facilitates the subsequent winding of the cables and the pulling action during maintenance. When the middle section of the cable is broken, it is also very convenient to connect the cables by pulling the cables on both sides of the broken part.

[0007] When the two broken cables are to be reconnected, since the device is provided with a redundant section support device, in order to facilitate the reconnection of the cables, the cables are provided with some redundancy that can continue to be pulled. When the cables are pulled, the third roller mounting frame is pressed downward by the hydraulic support rod under the action of tension, so that the cables that were originally bent at the redundant section support device can be straightened, so that the broken cables can be repaired without extending the cables. The provision of the first wire roller, the second wire roller and the redundant section support device can also provide the cables with a certain degree of mobility. When vibration occurs, the cables will not be broken due to the pulling force generated by the vibration. When the cables are installed, the top flap can be closed.
