Description

Technical Field

[0001] This application relates to the field of cables, and more specifically, to a long-distance, high-capacity overhead cross-linked polyethylene insulated cable. Background Technology

[0002] Long-distance, high-capacity overhead cross-linked polyethylene (XLPE) insulated cable is a type of cable used for power transmission. It uses XLPE as insulation material and possesses excellent electrical and mechanical properties, making it suitable for long-distance, high-capacity power transmission. Typically, the manufactured cable is wound onto a cable rack. Due to the weight of both the cable and the cable rack, large hoisting equipment is usually used for lifting. However, after transporting the coiled cable to the construction site, it needs to be released from the cable rack. This requires further lifting equipment, or the cable rack can be placed directly on the ground, and the cable can be disassembled piece by piece, causing inconvenience during cable installation. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a long-distance, high-capacity overhead cross-linked polyethylene insulated cable, which aims to improve the problem of inconvenience caused by the need to release the cable from the cable rack after transporting the coiled cable to the construction site, which requires the use of lifting equipment or placing one side of the cable rack directly on the ground and then disassembling the cable from the cable rack bit by bit.

[0004] This application provides a long-distance, high-capacity overhead cross-linked polyethylene insulated cable, including a cable body and a cable roller assembly. The cable roller assembly includes a circular frame, a connecting frame, an inner winding roller, a transmission component, and a driving component. The circular frames are symmetrically arranged. One side of the connecting frame is fixedly connected to one of the circular frames, and the other side of the connecting frame is fixedly connected to another circular frame. The inner winding roller is rotatably sleeved on the outside of the connecting frame, and the cable body is wound around the outside of the inner winding roller. The transmission component is rotatably connected to one of the circular frames, and one side of the transmission component is drively connected to one side of the inner winding roller. One side of the driving component is inserted inside one side of the circular frame, and the rotating end of the driving component is inserted inside the other side of the transmission component.

[0005] In one specific implementation, a plurality of bolts are spaced apart on one side of the circular frame, and the circular frame and the connecting frame are fixedly connected by the bolts.

[0006] In one specific implementation, the circular frame is provided with a plurality of first pulleys at intervals, and the inner roller of the winding is close to the surface of the first pulleys.

[0007] In one specific implementation, a plurality of second pulleys are provided around the connecting frame, and the inner side of the inner roller of the winding is close to the surface of the second pulleys.

[0008] In one specific implementation, the transmission component includes a first transmission shaft and a second transmission shaft, both of which are rotatably connected to the circular frame. The bottom of the first transmission shaft is connected to the inner roller of the winding, and the upper part of the first transmission shaft is connected to one end of the second transmission shaft. The rotating end of the driving component is inserted into the other end of the second transmission shaft.

[0009] In one specific implementation, a first bevel gear is provided on one side of the inner roller of the winding, a second bevel gear is provided at the bottom of the first drive shaft, a third bevel gear is provided at the upper part of the first drive shaft, a fourth bevel gear is provided at one end of the second drive shaft, and an internal hexagon block is provided at the other end of the second drive shaft. The first bevel gear is meshed with the second bevel gear, and the third bevel gear is meshed with the fourth bevel gear.

[0010] In one specific implementation, the driving component includes a motor and an outer frame. The motor output end is provided with a hexagonal head, which is inserted into the interior hexagonal block. The motor is fixedly connected to the outer frame, and one side of the outer frame is inserted into one side of the circular frame.

[0011] In one specific implementation, a limiting frame is provided on one side of the circular frame, and one side of the limiting frame is locked onto one side of the outer frame.

[0012] Beneficial Effects: This application provides a long-distance, high-capacity overhead cross-linked polyethylene insulated cable. During the cable production stage, the finished cable is first tightly wound around the outer circumference of the inner winding roller. Then, the rotating end of the drive component is inserted into the rotating end of the transmission component, forming a transmission connection. The torque output by the drive component drives the transmission component to rotate, thereby driving the inner winding roller to rotate synchronously, providing stable power for the cable winding process and assisting the cable to be wound evenly and tightly onto the inner winding roller. During this winding process, the circular frames connected to both ends of the inner winding roller need to be limited and fixed to prevent displacement of the circular frames when the inner winding roller rotates, ensuring the stability of the winding operation. After the coiled cable arrives at the construction site via transport, the entire cable coil is first unloaded onto the ground, so that both circular frames are placed stably on the ground, forming a symmetrical support structure. At this time, the two circular frames need to be limited and fixed again to prevent displacement of the circular frames. If slippage or offset occurs during subsequent release, the installation position of the drive component is adjusted, and one side of the outer frame is embedded into the circular frame for positioning. A limit bracket is used to limit the outer frame, and a hexagonal head is inserted into the inner hexagonal block to create a new transmission path. After the motor is started, its output end drives the transmission component to rotate, which in turn drives the inner roller of the cable reel to rotate along its own axis. This causes the cable, which was originally wrapped around the outer circumference of the inner roller, to gradually unwrap under the rotation of the inner roller, achieving stable cable release. Through the above operations, in the cable laying construction process, there is no need to rely on large hoisting equipment to suspend the cable reel, nor is it necessary to use the traditional method of placing a single circular frame on the ground at an angle and manually disassembling the cable step by step. This effectively simplifies the operation process, reduces dependence on construction equipment, and avoids the risks of cable jamming, pulling, or the circular frame tipping over during manual disassembly, significantly improving the convenience and efficiency of cable laying.

[0018] Please see Figures 1-6The cable roller assembly 200 includes a circular frame 210, a connecting frame 220, an inner winding roller 230, a transmission component 240, and a driving component 250. The circular frames 210 are symmetrically arranged. One side of the connecting frame 220 is fixedly connected to one circular frame 210, and the other side of the connecting frame 220 is fixedly connected to another circular frame 210. The inner winding roller 230 is rotatably sleeved on the outside of the connecting frame 220, and the cable body 100 is wound around the outside of the inner winding roller 230. The transmission component 240 is rotatably connected to one circular frame 210, and one side of the transmission component 240 is connected to one side of the inner winding roller 230. The driving component 250 is connected to one side of the inner winding roller 230. Inserted inside one side of the circular frame 210, the rotating end of the drive component 250 is inserted inside the other side of the transmission component 240. Multiple bolts 211 are spaced apart on one side of the circular frame 210, and the circular frame 210 and the connecting frame 220 are fixedly connected by bolts 211. Multiple first pulleys 212 are spaced apart on the circular frame 210, and the inner roller 230 is close to the surface of the first pulleys 212. Multiple second pulleys 221 are arranged around the periphery of the connecting frame 220, and the inner side of the inner roller 230 is close to the surface of the second pulleys 221. The transmission component 240 includes a first transmission shaft 241 and a second transmission shaft 242. Both drive shaft 241 and second drive shaft 242 are rotatably connected to the circular frame 210. The bottom of the first drive shaft 241 is connected to the inner winding roller 230, and the upper part of the first drive shaft 241 is connected to one end of the second drive shaft 242. The rotating end of the drive component 250 is inserted inside the other end of the second drive shaft 242. A first bevel gear 231 is provided on one side of the inner winding roller 230, a second bevel gear 243 is provided at the bottom of the first drive shaft 241, a third bevel gear 244 is provided at the upper part of the first drive shaft 241, and a fourth bevel gear 245 is provided at one end of the second drive shaft 242. The other end of the drive shaft 242 is provided with an internal hexagon block 246. The first bevel gear 231 is meshed with the second bevel gear 243, and the third bevel gear 244 is meshed with the fourth bevel gear 245. The drive unit 250 includes a motor 251 and an outer frame 252. The output end of the motor 251 is provided with a hexagon head 253, which is inserted into the internal hexagon block 246. The motor 251 is fixedly connected to the outer frame 252. One side of the outer frame 252 is inserted into one side of the circular frame 210. A limit frame 214 is provided on one side of the circular frame 210, and one side of the limit frame 214 is locked onto one side of the outer frame 252.

[0019] The working principle of this long-distance, high-capacity overhead cross-linked polyethylene insulated cable is as follows: During the winding stage of the cable body 100, two symmetrical circular frames 210 and the connecting frame 220, fixedly connected by bolts 211, form a supporting base. The inner winding roller 230 is rotated and sleeved on the outside of the connecting frame 220. One side of the outer frame 252 of the driving component 250 is inserted into the circular frame 210, and the hexagonal head 253 of the output end of the motor 251 is inserted into the inner hexagonal block 246 of the second transmission shaft 242 in the transmission component 240, thus starting the cable. After the motor 251, the torque is transmitted to the third bevel gear 244 of the first drive shaft 241 via the fourth bevel gear 245 of the second drive shaft 242. Then, the second bevel gear 243 at the bottom of the first drive shaft 241 meshes with the first bevel gear 231 on one side of the inner winding roller 230, driving the inner winding roller 230 to rotate around the connecting frame 220. At the same time, the second pulley 221 on the periphery of the connecting frame 220 and the first pulley 212 of the circular frame 210 assist the inner winding roller 230 to rotate smoothly, realizing the rotation of the cable body. The cable is evenly wound around the inner roller 230, with the circular frame 210 being limited to prevent displacement. During the cable release phase, the cable roller assembly 200, including the cable body 100, is unloaded onto the ground. The two circular frames 210 land smoothly and are limited again. The drive unit 250 is positioned by engaging with the limiting frame 214 of the circular frame 210 via the outer frame 252. The hexagonal head 253 still engages with the inner hexagonal block 246. When the output of the motor 251 drives in the reverse direction, the torque drives the inner roller 230 through the same transmission path. The cable reel rotates in the opposite direction at 30, causing the cable body 100 to gradually unfold from the outside of the inner roller 230, thus releasing the cable. This eliminates the need for large hoisting equipment to lift the cable reel in mid-air, and also eliminates the need for the traditional method of placing the single circular frame 210 at an angle on the ground and manually disassembling the cable step by step. This effectively simplifies the operation process, reduces reliance on construction equipment, and avoids the risks of cable jamming, pulling, or the circular frame 210 tipping over during manual disassembly, significantly improving the convenience and efficiency of cable installation.
