Description

Technical Field

[0001] The utility model relates to the technical field of cable laying, in particular to a power supply cable laying device for coal mine power supply. Background Art

[0002] Coal mine power supply refers to the safe, reliable, continuous, and qualified distribution of electrical energy to coal mines through transmission and distribution equipment. This process requires the laying of cables. Cables are typically composed of several or several groups of conductors twisted together, similar to ropes. Each group of conductors is insulated from each other and often twisted around a central core. The entire cable is covered with a highly insulating sheath, characterized by internal current flow and external insulation. Cables are widely used in a variety of industries, including oil fields and mines, construction, machinery manufacturing, scientific research, ports and terminals, shopping malls, hotels, and road and bridge construction. As industrial demand becomes increasingly diverse, their use is expected to increase. Existing cables are typically laid manually. During the laying process, the cables are coiled, resulting in a certain degree of curvature, requiring straightening during use. Manual straightening is difficult when laying long cables, increasing the difficulty, hindering the construction process, and causing inconvenience.

[0003] In the prior art, for example, Chinese patent publication number CN214013701U discloses a power supply cable laying device for coal mine power supply, which includes a supporting load-bearing plate, one end of which is equipped with an adjustable push rod device, and the other end of the supporting load-bearing plate is provided with a high-efficiency cable straightening box, and the four corners of the lower bottom surface of the supporting load-bearing plate are connected to convenient roller devices; a control panel is installed at the lower end of one side of the high-efficiency cable straightening box, and an high-efficiency cable straightening device is provided inside the high-efficiency cable straightening box.

[0004] Although the above device can straighten the cable, in actual use, the cable is straightened by the roller at the bottom of the straightening box contacting the cable. The roller is fixed in the box and the height remains unchanged. During use, it cannot be guaranteed that the roller can be in close contact with the cable, resulting in insufficient straightening effect. For this reason, we propose a power supply cable laying device for coal mine power supply to solve the above problem. Utility Model Content

The support plates 202 at both ends are symmetrically distributed along the axis of the unwinding roller 201. The support plates 202 are rotatably connected to the unwinding roller 201, and the bottom of the support plate 202 is fixedly connected to the table of the movable platform 1. A servo motor 203 is provided on one side of the support plate 202. The output end of the servo motor 203 is fixedly connected to the unwinding roller 201, and the output end of the servo motor 203 coincides with the axis of the unwinding roller 201. The servo motor 2 A fixing seat 204 is sleeved on the surface of 03, which is fixedly connected to the servo motor 203. The end of the fixing seat 204 away from the servo motor 203 is fixedly connected to the support plate 202. The surface of the unwinding roller 201 is wrapped with a cable body 205. The end of the cable body 205 away from the unwinding roller 201 passes through the straightening component 3. During the laying process, the cable can be released and released through the unwinding roller 201. The unwinding roller 201 is driven by the servo motor 203 to ensure that the cable is released smoothly from the reel. The servo motor 203 can accurately adjust the unwinding speed to prevent the cable from tangling, twisting, or other damage during the unwinding process.

[0026] Furthermore, a working box 301 is provided in the straightening component 3, and the bottom of the working box 301 is fixedly connected to the side of the top of the movable platform 1 away from the unwinding component 2, and a connecting window 302 is provided on the surface of the working box 301, and the end of the cable body 205 away from the unwinding roller 201 passes through the connecting window 302, and the inner cavity of the working box 301 is provided with a plurality of guide wheels 308 for straightening the cable body 205, and the guide wheels 308 are distributed on the upper and lower sides of the cable body 205, and the guide wheels 308 on both sides are symmetrically distributed along the cable axis, and a fixed roller 307 is sleeved in the middle of the guide wheel 308, and the fixed roller 307 is rotatably connected to the guide wheel 308, and connecting plates 306 are sleeved at both ends of the fixed roller 307, and the connecting plates 306 at both ends are symmetrically distributed along the axis of the fixed roller 307. 7 is fixedly connected, and the end of the connecting plate 306 away from the fixed roller 307 is sleeved with the rotating roller 304, and the rotating roller 304 is fixedly connected to the connecting plate 306. The two ends of the rotating roller 304 are sleeved with torsion springs 305, and the surface of the torsion spring 305 is sleeved with a mounting cylinder 303. The end of the mounting cylinder 303 away from the rotating roller 304 is fixedly connected to the inner wall of the working box 301, one end of the torsion spring 305 is fixedly connected to the inner wall of the mounting cylinder 303, and the other end of the torsion spring 305 is fixedly connected to the surface of the rotating roller 304. The cable is straightened by passing through multiple guide wheels 308. Compared with the existing device, its multiple guide wheels 308 will be close to the cable under the drive of the torsion spring 305, and its straightening effect is better and can adapt to cables of different diameters. The design of the guide wheel 308 allows the cable to remain straight when passing through to avoid bending or twisting. The guide roller 308 system typically consists of a fixed roller 307 and a rotating roller 304. The fixed roller 307 stabilizes the cable path, while the rotating roller 304 adjusts the cable tension. A torsion spring 305 assembly in the system allows the guide roller 308 to adhere closely to the cable, accommodating cables of varying specifications. Through precisely controlled unwinding and straightening mechanisms, the device significantly improves cable laying efficiency.

[0027] Working principle: When using this device, the cable is released through the unwinding roller 201, which is driven by the servo motor 203 to ensure that the cable is released smoothly from the reel. The servo motor 203 can accurately adjust the unwinding speed to prevent the cable from getting tangled, twisted or otherwise damaged during the unwinding process. The system is also equipped with a straightening device to maintain appropriate tension and prevent the cable from being subjected to excessive stress during the unwinding process. After the cable comes out of the unwinding system, it enters the straightening component 3 of the working box 301. There are multiple guide wheels 308 installed inside the working box 301. These guide wheels 308 are reasonably distributed and can effectively straighten the cable. The design of the guide wheel 308 allows the cable to remain straight as it passes, avoiding bending or twisting. The guide wheel 308 system usually includes a fixed roller 307 and a rotating roller 304. The fixed roller 307 is used to stabilize the path of the cable, and the rotating roller 304 is responsible for adjusting the tension of the cable. The torsion spring 305 component in the system can make the guide wheel 308 close to the cable, thereby adapting to cables of different specifications. Through the precisely controlled unwinding and straightening mechanism, the device greatly improves the efficiency of cable laying. The cooperation between the guide wheel 308 system and the servo motor 203 ensures that the cable always remains straight during the laying process, reducing the risk of cable damage or improper laying. The device can handle cables of different diameters and adapt to cables of various specifications through the torsion spring 305 and guide wheel 308 system.
