Description

Technical Field

[0001] This utility model belongs to the field of cable laying technology, and specifically relates to a cable laying device. Background Technology

[0002] By laying electrical wires and cables underground or inside walls using installation devices, the wires can be effectively isolated from the outside world, avoiding the danger of accidental contact with the wires. At the same time, it reduces the risk of damage and aging of the wires and cables due to external factors, thereby ensuring electrical safety.

[0003] The common method for laying cables is to first dig a trench, then support the cable reel with brackets, pull the cable reel to release the cable, and then straighten the cable in the trench. As the length of the cable increases, the difficulty of pulling the cable also increases significantly. Manual dragging is very strenuous, and sometimes even a towing vehicle is needed. When encountering corners, manual adjustment is required in real time, which is quite troublesome. In addition, pulling long cables can easily damage them. Utility Model Content

[0004] To address the above problems, the purpose of this utility model is to provide a cable laying device that solves the common cable laying method. Generally, a trench is dug first, then a cable reel is supported by a bracket, and then the cable reel is pulled to release the cable. The cable is then pulled straight in the trench. As the length of the cable increases, the difficulty of pulling the cable also increases significantly. Manual dragging is very strenuous, and sometimes even a towing vehicle is needed. When encountering corners, manual adjustment is required in real time, which is quite troublesome. In addition, pulling long cables can easily damage them.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cable laying device, comprising a support plate, with movable wheels provided at the four lower corners of the support plate, a handle frame provided on one side of the support plate, uprights symmetrically arranged on both sides of the upper side of the support plate, a support block provided on the upper side of the upright on the same side, a shaft rotatably arranged on the upper side of the support block, a cable reel provided on the outer side of the shaft, a fixing rod symmetrically arranged on one side of the upper side of the support plate, a crossbar provided on the side of the fixing rod away from the cable reel, a connecting rod provided at the end of the crossbar away from the fixing rod, a fixing plate provided at the end of the connecting rod close to each other, a screw threaded on the upper side of each fixing plate, a wire-passing ring provided at the lower end of the screw penetrating the fixing plate, and an insert rod inserted at the upper end of the screw.

[0006] The beneficial effects of this utility model are as follows: by pushing the support plate forward with the handle frame, the support plate drives the cable reel forward.

[0035] Working principle and usage process of this utility model:

[0036] In use, move the device to one side of the groove so that the lower end of the screw 13 is inside the groove. Pull out the cable end of the reel 7 and pass it through the threading ring 15 at the lower end of the screw 13. Fix the cable end to one end of the groove. Then, push the support plate 1 forward along the edge of the groove using the handle 2. The support plate 1 drives the reel 7 forward. As the reel 7 moves forward, the cable will be released simultaneously and pass through the threading ring 15, laying it along the groove. This allows the cable to be laid as it is laid along the groove. The cable can be laid wherever it is needed, without the need to first lay out the cable and then drag it. It can be laid forward along the trench without the need for a tractor, greatly increasing the convenience of laying and effectively avoiding cable damage caused by pulling long lines. Furthermore, during use, support rollers 5 are symmetrically arranged on the upper side of the support block 4, and the shaft 6 is placed on the upper side of the support rollers 5. The support rollers 5 support the shaft 6, facilitating quick loading and unloading of the shaft 6. Additionally, during use, nuts 61 are symmetrically threaded on both sides of the shaft 6 and the cable reel 7. Each of the 61 has a screw cylinder 62 on one side close to the other. A pressure plate 63 is rotatably mounted on the outside of the screw cylinder 62. The pressure plate 63 is located on both sides of the reel 7. Tightening the nut 61 causes the pressure plate 63 to clamp the two sides of the reel 7, which helps to maintain the stability of the reel 7 when feeding the wire. In addition, the output end of the hydraulic telescopic rod 17 pushes the support block 4 to move up and down along the adjustment groove 18, which facilitates quick loading and unloading of the reel 7 from the notch groove 16. In addition, when in use, the cable is passed between the pressure roller 84 and the feeding roller 83. The output end of the motor 82 drives the feeding roller 83 to rotate, which can feed the cable and feed the wire onto the reel 7, making the feeding of the reel 7 easier. In addition, when in use, tightening the bolt 89 causes the bolt 89 to move the pressure roller 84 up and down through the end block 87, which helps to adjust the distance between the pressure roller 84 and the feeding roller 83 according to the thickness of the cable. In addition, when in use, the outer surfaces of the support roller 5, the feeding roller 83 and the pressure roller 84 are all made of rubber to increase the friction of the contact surface.
