[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-8 The utility model provides a technical solution: a low-voltage cable pipe-threading traction device, comprising a frame 100, a Mecanum wheel 200 and a driving assembly 300 respectively arranged on the front and rear sides of the frame 100, and a docking end 400 for positioning the end of the low-voltage cable, the output end of the driving assembly 300 passes through the frame 100 and is fixedly connected to the Mecanum wheel 200, the frame 100 comprises a fixing plate 110 and a plurality of supporting wheels 120 distributed in a ring array, the plurality of supporting wheels 120 are all rollingly fitted with the inner wall of the power pipe, the driving assembly 300 comprises a servo motor 310 mounted on the back of the fixing plate 110 and a bracket 320 covered on the outside of the servo motor 310, a power supply 330 and a control box 340 distributed in an upper and lower manner are respectively arranged on the inner side wall of the bracket 320 and located behind the servo motor 310, and the servo motor 310, the power supply 330 and the control box 340 are electrically connected in pairs.

[0035] Based on the above-mentioned structural setting, the low-voltage cable pipe-threading traction device is composed of a frame 100, a Mecanum wheel 200, a drive assembly 300 and a docking end 400, wherein the frame 100 is supported on the inner wall of the power pipe, providing structural support for the installation of the Mecanum wheel 200 and the drive assembly 300, and the docking end 400 is arranged at the rear of the drive assembly 300 to dock and assemble the end of the low-voltage cable on the equipment. Specifically, during the working process, the operator first assembles one end of the low-voltage cable on the docking end 400, and then the operator embeds the equipment in the power pipe, and starts the servo motor 310 with the help of the power supply 330 and the control box 340. The output end of the servo motor 310 rotates to drive the Mecanum wheel 200 to rotate, and the side of the Mecanum wheel 200 is in contact with the inside of the power pipe. The wall of the power pipe is fitted, driving the equipment to move forward along the axis of the power pipe in the power pipe, and at the same time, driving the low-voltage cable to perform the pipe threading operation until the equipment is output at the other end of the power pipe. The operator turns off the servo motor 310 and removes the low-voltage cable, that is, the threading operation of the low-voltage cable in the power pipe is completed. The low-voltage cable pipe threading traction device is provided with a Mecanum wheel 200 coaxially adapted to the inner wall of the power pipe. With the help of a drive assembly 300 fixedly installed on the frame 100, the Mecanum wheel 200 can be driven to rotate, so that the entire equipment can move forward along its axis in the power pipe. At the same time, the end of the low-voltage cable can be fixedly installed on the equipment in conjunction with the docking end 400, thereby realizing the pipe threading traction operation of the low-voltage cable. Compared with the manual pipe threading operation, the operation is convenient and the pipe threading efficiency is greatly improved.

[0036] Furthermore, the support wheel 120 includes a guide frame 1210 distributed along the radial direction of the power pipe and a mounting frame 1220 slidably embedded in the guide frame 1210, as well as a first screw rod 1230 threadedly passing through the guide frame 1210 and a roller 1240 installed on the guide frame 1210, one end of the first screw rod 1230 passes through the mounting frame 1220 and is rotatably connected to the mounting frame 1220. Among them, the Mecanum wheel 200 is rotated by means of a servo motor 310. In order to ensure the stable forward movement of the equipment in the power pipe, it is necessary to ensure the stable installation of the rack 100 in the power pipe as much as possible, that is, with the help of a number of support wheels 120 distributed in a ring array, the fixed plate 110 is installed in the power pipe. Preferably, with the help of a sliding-adapted mounting frame 1220 and a guide frame 1210, in conjunction with the first screw 1230, the operator can realize the outward movement of the mounting frame 1220 in the guide frame 1210 by screwing in the first screw 1230, so as to ensure that each roller 1240 is supported on the inner wall of the power pipe, further ensuring the stable installation of the rack 100 on the inner wall of the power pipe, so that the rack 100 only moves along the axial direction of the power pipe.

[0037] Furthermore, the docking end 400 includes a barrel shell 420 welded to the back of the bracket 320 and having limit holes 410 on both sides, a pressure frame 430 extending horizontally between the two limit holes 410, and a lining plate 440 glued to the bottom of the inner wall of the barrel shell 420, and a second screw rod 450 extending vertically through the top of the barrel shell 420, the bottom end of the second screw rod 450 extending through the pressure frame 430 and being rotatably connected to the pressure frame 430. The docking end 400 is used to realize the assembly between the low-voltage cable and the equipment. Specifically, the operator inserts the end of the low-voltage cable into the barrel shell 420, and at the same time, the operator tightens the second screw rod 450, and the pressure frame 430 moves down along the two limit holes 410, and cooperates with the lining plate 440 to clamp and fix the end of the low-voltage cable, thereby completing the fixed installation of the end of the low-voltage cable in the docking end 400, which is convenient to operate.

[0038] Furthermore, the bottom surface of the pressing frame 430 is parallel to the top surface of the lining plate 440, and both surfaces are covered with a rubber pad 460. The provision of the rubber pad 460 can, on the one hand, provide effective protection for the end of the low-voltage cable, and on the other hand, increase the friction force of the low-voltage cable being clamped, further ensuring the reliable and stable connection between the end of the low-voltage cable and the equipment.

[0039] Furthermore, the device also includes an end plate 500 coaxially mounted on the front of the Mecanum wheel 200, and the side of the end plate 500 is adapted to the inner wall of the power pipe. The power pipe usually contains debris such as sand and gravel. As the device moves forward in the power pipe, the debris in the power pipe may affect the rotation of the Mecanum wheel 200, or even damage the Mecanum wheel 200. Preferably, the end plate 500 is mounted on the front of the Mecanum wheel 200 to separate the debris from the device, thereby providing effective protection for the device and cleaning the debris in the power pipe.
