Description

Technical Field

[0001] This invention relates to the field of cable handling technology, specifically to a cable handling device for power transmission lines. Background Technology

[0002] Transmission lines are constructed by using transformers to step up the voltage of electrical energy generated by generators, and then connecting it to the transmission line via control equipment such as circuit breakers. Based on their structural form, transmission lines can be divided into overhead transmission lines and cable lines. Currently, with the rapid development of the power industry, the use of cables is also gradually increasing. A large number of cables are needed in the construction of transmission lines, and the cables are generally wound on cable reels.

[0003] Currently, various sizes of cable reels are required in power transmission line applications. When winding and unwinding these reels, it's inconvenient to limit cable movement, potentially leading to tangling and affecting usability. Furthermore, when winding cables of different sizes, even uniform winding during the process cannot adaptively adjust the reciprocating speed based on cable size and winding diameter. This can result in excessive gaps or over-compression between cables after winding. Real-time adjustment of the reciprocating speed during winding is cumbersome, impacting winding efficiency. Additionally, when transporting cables using hoisting equipment, movement after hoisting can cause swaying, affecting subsequent placement, indicating certain operational drawbacks.

[0004] Therefore, we propose a cable handling device for power transmission lines to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a cable handling device for power transmission lines, which solves the problems mentioned in the background art, namely, the inability to adaptively adjust the reciprocating winding speed of the cable according to the size of the cable and the diameter of the winding, the tendency for cables of different sizes to have excessive gaps or excessive compression between the cables after winding, and the cumbersome adjustment process when adjusting the reciprocating winding speed in real time during the winding process, which affects the winding efficiency of the cable.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cable handling device for power transmission lines, comprising a base and a roller, a placement frame fixedly installed on the top of the base, and a number of placement slots symmetrically opened on the top of the placement frame, and rotating rings symmetrically rotatably connected to the outer sides of the roller, while hanging ropes are fixedly installed on the outer sides of the two rotating rings.

[0013] Preferably, a turntable is fixedly installed on the side of the rotating rod away from the support plate, and a column block is fixedly installed on one side of the turntable.

Meanwhile, a moving rod is fixedly installed on one side of the movable frame, and a limit plate is slidably connected to the outside of the moving rod. The limit plate is fixedly connected to the upright plate on the other side.

[0014] By adopting the above technical solution, the rotation of the turntable can drive the movable frame to move back and forth.

[0015] Preferably, an L-shaped frame is fixedly installed on the top of the movable frame, and fixed plates are symmetrically installed on one side of the two support plates on the top of the base.

[0016] By adopting the above technical solution, the moving seat can be moved by the rotation of the reciprocating lead screw.

[0017] Preferably, the rotating seat has ratchet teeth symmetrically hinged inside, and a torsion spring is provided at the connection between the ratchet teeth and the rotating seat. A positioning frame is fixedly installed on one side of the rotating seat, and a connecting shaft is rotatably connected inside the positioning frame. A ratchet is fixedly installed at one end of the connecting shaft, and the ratchet teeth are engaged with the ratchet. A rotating gear is fixedly installed at the other end of the connecting shaft.

[0018] By adopting the above technical solution, the reciprocating lead screw is prevented from rotating during the reset movement of the movable frame.

[0019] Preferably, a fixed block is fixedly installed on one side of the top of the L-shaped frame, and a movable rod is slidably connected inside the fixed block. A movable seat is fixedly installed at one end of the movable rod, and a rack is fixedly installed on the top of the movable seat. The rack meshes with a rotating gear, and a telescopic spring is sleeved on the outside of the movable rod on one side of the fixed block.

A T-shaped block is fixedly installed on one side of the bottom of the movable seat, and a T-shaped groove is opened on the top of the L-shaped frame below the movable seat. The T-shaped block is slidably connected to the T-shaped groove.

[0020] By adopting the above technical solution, the movement of the movable seat can drive the rotating gear to rotate, which in turn can drive the reciprocating lead screw to rotate.

[0021] Preferably, a mounting bracket is fixedly installed on the side of the movable seat away from the movable rod, and sliding rods are symmetrically slidably connected to the upper part of the mounting bracket. A return spring is sleeved on the outer side of each of the two sliding rods. A connecting plate is fixedly installed at one end of each of the two sliding rods, and a movable plate is fixedly installed at the other end of each of the two sliding rods. The two ends of the return springs are fixedly connected to the connecting plate and the mounting bracket, respectively.

A positioning groove is opened at the top of the L-shaped frame below the mounting bracket, and the positioning rod is inserted into the positioning groove.

[0022] By adopting the above technical solution, the movable seat can be positioned, thus avoiding the situation where the rack and rotating gear cannot move together with the L-shaped frame due to resistance after the rack and rotating gear mesh when the connecting plate does not abut against the L-shaped plate.

[0023] Preferably, a U-shaped frame is fixedly installed on the top of the two fixed plates, and through slots are symmetrically opened on both sides of the U-shaped frame.

[0024] By adopting the above technical solution, the distance between the two rollers can be adjusted by moving the movable plate, which facilitates the winding of cables of different sizes.

[0025] Preferably, a limiting frame is fixedly installed on the upper side of one side of the fixed plate, and a movable frame is slidably connected inside the limiting frame. An L-shaped plate is fixedly installed at one end of the movable frame, and a guide block is fixedly installed on the top of the L-shaped plate.

[0026] By adopting the above technical solution, the L-shaped plate can be moved while the movable plate moves.

[0027] Preferably, the handling assembly includes gantry frames symmetrically mounted on the top of the base above the placement frame, with a threaded rod rotatably connected to one side between the two gantry frames, and a handling frame connected to the external thread of the threaded rod. A winch is provided on the top of the handling frame, and a stepper motor is fixedly mounted on the upper side of one gantry frame. The output end of the stepper motor passes through one gantry frame and is fixedly connected to the threaded rod. A crossbar is slidably connected to the inner side of the handling frame, and both ends of the crossbar are fixedly connected to the two gantry frames. A wire rope is wound around the outer side of the winch.

[0028] By adopting the above technical solution, it is easier to handle the cables.

[0029] Preferably, a hook is fixedly installed at the bottom end of the wire rope, and an installation plate is fixedly installed on the outside of the wire rope above the hook. Vertical rods are symmetrically slidably connected inside the installation plate, and the top ends of the two vertical rods are evenly connected to the transport frame.

[0030] By adopting the above technical solution, the swaying of the wire rope is reduced, making it easier to place the drum.

[0031] Compared with the prior art, the beneficial effects of the present invention are: the cable handling device for transmission lines prevents the cable spacing from becoming too large or too small due to differences in size or changes in the cable rolls after winding, thus ensuring a tight fit after winding and improving the quality of cable winding. At the same time, the cable winding speed can be adjusted according to the thickness of the cable itself, avoiding frequent adjustments to the reciprocating winding speed during cable winding and ensuring cable collection efficiency, thus having better applicability.

[0032] 1. During the cable winding process in power transmission line construction, the roller is placed on two support plates, allowing the rotating ring to enter the receiving groove. During placement, the connecting block slides into the connecting groove on the connecting seat. Then, one end of the cable is wound around the roller, passing the cable through the two rollers. Rotating the screw moves the movable plate downwards, causing the moving block to move downwards. The moving block, connected to the movable groove, moves the two adjusting frames closer together, allowing the two rollers to clamp the cable. Simultaneously, the movable plate moves downwards, causing the column to move downwards via the connecting frame. The column, after moving downwards, slides in the sliding groove, moving the guide block and thus causing the L-shaped plate to move closer to the L-shaped frame. This allows the L-shaped plate to move more significantly as the cable size decreases. Then, the servo motor can be activated to rotate the rollers, which in turn wind the cable. The rollers' rotation drives a turntable, causing the cylindrical blocks on the turntable to rotate circumferentially. The rotation of these blocks, through a sliding connection with the movable frame, drives the movable frame to reciprocate, which in turn drives the L-shaped frame to reciprocate. This causes the rack and pinion gears to mesh and rotate, driving the connecting shaft to rotate. The connecting shaft then drives the ratchet, which in turn pulls the ratchet teeth, causing the rotating seat to rotate. This, in turn, drives the reciprocating screw, which in turn moves the movable seat. When the L-shaped frame returns to its original position, the rotating gears rotate in the opposite direction and no longer drive the reciprocating screw to return to its original position. Initially, a single reciprocating movement of the movable frame causes the reciprocating screw to rotate one revolution, which in turn causes the drum to rotate one revolution, thus driving the reciprocating screw to rotate one revolution. When winding smaller cables, the L-shaped plate moves closer to the L-shaped frame. Before the movable frame reaches its maximum distance, the L-shaped plate can block and limit the movement of the moving seat. If the L-shaped frame continues to move, the movable rod slides on the fixed block and stretches the telescopic spring. At this point, the rack stops moving and therefore does not drive the reciprocating screw to rotate. This allows for an adaptive reduction in the rotation position of the reciprocating screw during one revolution of the drum when winding thinner cables, thereby reducing the displacement of the movable seat and ensuring the drum rotates one revolution. Afterwards, the cable is wound up once, and simultaneously, it can be intermittently wound back and forth using two rollers. During the reciprocating winding process, the position of the movable seat can be adaptively adjusted according to the cable size. This prevents the cable from having excessively large or small gaps after winding due to differences in cable size or changes in the cable rolls after winding, ensuring a tight fit after winding and improving the quality of cable winding. At the same time, the cable winding speed can be adjusted according to the cable's thickness, avoiding frequent adjustments to the reciprocating winding speed during cable winding and ensuring cable collection efficiency, making it more applicable.

[0033] 2. When adjusting the rotational displacement of the reciprocating screw, before the moving seat reaches its limit distance, the connecting plate first abuts against the L-shaped plate. Then, as the moving seat continues to move, the mounting bracket slides outside the sliding rod, compressing the return spring, which drives the connecting rod to rotate. The rotation of the connecting rod pulls the positioning rod upward, causing the positioning rod to disengage from the positioning groove. This causes the moving seat to lose its limit on the L-shaped frame. After that, the movement of the L-shaped frame will no longer drive the moving seat to move. When the L-shaped frame returns to its original position and the connecting plate separates from the L-shaped plate, the positioning rod returns to its original position under the action of the return spring. This allows the positioning rod to insert into the positioning groove to position the moving seat. This prevents the moving seat from being unable to move with the L-shaped frame due to resistance when the rack and rotating gear mesh when the connecting plate is not abutting against the L-shaped plate, thus avoiding affecting the subsequent cable winding work.

[0034] 3. When handling cable reels, the winch can be started to unwind the wire rope, causing the hook to descend and the rope to be hooked onto the hook. The winch can then be started to wind the wire rope, raising the drum. As the hook moves upward, it can move the mounting plate, allowing the mounting plate to slide on the vertical rod to prevent the wire rope from swinging unexpectedly. Then, the stepper motor can be started to rotate the threaded rod, which can move the transport frame. After the transport frame moves to the appropriate position, the wire rope can be unwound, causing the drum to fall. The rotating ring on the drum can then be placed in the placement slot. Multiple drums can be placed using the placement frame. The base facilitates the handling of cables and reduces the swaying amplitude of the cable reel during handling, making it easier to place the cable reel in the subsequent placement process.

A column rod 257 is fixedly installed on the side of the connecting frame 251 away from the fixed plate 214. The column rod 257 is slidably connected to the sliding groove 256.

[0060] Example 1: As Figures 1-7 and Figures 9-10As shown, during the cable winding process in the construction of the transmission line, the roller 102 is placed on two support plates 201, so that the rotating ring 103 is placed into the receiving groove 202. During placement, the connecting block 104 slides into the connecting groove 207 on the connecting seat 206. Then, one end of the cable can be wound around the roller 102 and passed through the two rollers 246. The screw 240 is rotated to move the movable plate 241 down. After the movable plate 241 moves down, the moving block 249 moves down. After the moving block 249 moves down, the connection between the movable block 248 and the movable groove 250 can drive the two adjusting frames 245 to move closer together, so that the two rollers 246 can clamp the cable. At the same time as the movable plate 241 moves down, the connecting frame 251 can drive the column 25. 7. After the column 257 moves down, it slides in the sliding groove 256, which drives the guide block 255 to move. This causes the L-shaped plate 254 to move closer to the L-shaped frame 213. The smaller the cable size, the greater the displacement of the L-shaped plate 254. Then, the servo motor 205 can be started to rotate, causing the roller 102 to rotate and wind up the cable. During the rotation of the roller 102, the turntable 208 can be rotated, causing the column block 209 on the turntable 208 to rotate circumferentially. The rotation of the column block 209 can drive the movable frame 210 to move back and forth through the sliding connection with the movable frame 210. This can drive the L-shaped frame 213 to move back and forth, causing the rack 228 to move and mesh with the rotating gear 223, which drives the connecting shaft 220 to rotate. The connecting shaft 220 drives the ratchet 22... When the L-shaped plate 254 rotates, the ratchet 221 and ratchet 222 pull the rotating seat 218 to rotate, which in turn drives the reciprocating screw 215 to rotate, thereby moving the movable seat 216. When the L-shaped frame 213 moves to its reset position, the rotating gear 223 rotates in the opposite direction and will no longer drive the reciprocating screw 215 to reset. In the initial state of the L-shaped plate 254, one reciprocating movement of the movable frame 210 can cause the reciprocating screw 215 to rotate one revolution, which in turn causes the roller 102 to rotate one revolution, thus driving the reciprocating screw 215 to rotate one revolution. When winding up small cables, the L-shaped plate 254 moves closer to the L-shaped frame 213. Before the movable frame 210 has moved to its farthest distance, the movement of the movable seat 226 can be controlled by the L-shaped plate 254. When the L-shaped frame 213 continues to move, the movable rod 225 slides on the fixed block 224 and stretches the telescopic spring 227. At this time, the rack 228 no longer moves, thus preventing the reciprocating screw 215 from rotating. This allows for adaptive shortening of the rotation position of the reciprocating screw 215 when the roller 102 rotates once when winding up thinner cables. This reduces the displacement of the movable seat 216, ensuring that the cable is wound up once after the roller 102 rotates once. Simultaneously, the cable can be intermittently wound back and forth through the two rollers 246. During the reciprocating winding process, the position of the movable seat 216 can be adaptively adjusted according to the cable size, allowing for different cable sizes to be wound up simultaneously.To avoid excessively large or small cable spacing after winding due to differences in cable size or changes in the spacing between cable rolls, this method ensures a tight fit after winding, improving the quality of cable winding. Furthermore, it allows for adjustment of the cable winding speed according to its thickness, avoiding frequent adjustments to the reciprocating winding speed during the winding process and ensuring efficient cable collection, thus offering better applicability.

[0061] A mounting bracket 231 is fixedly installed on the side of the movable base 226 away from the movable rod 225. Sliding rods 232 are symmetrically slidably connected to the upper part of the mounting bracket 231. A return spring 233 is sleeved on the outer side of each of the two sliding rods 232. A connecting plate 234 is fixedly installed on one end of each sliding rod 232, and a moving plate 235 is fixedly installed on the other end of each sliding rod 232. The two ends of the return spring 233 are fixedly connected to the connecting plate 234 and the mounting bracket 231, respectively. A connecting rod 236 is hinged to the bottom of the moving plate 235. A positioning rod 237 is hinged to the end of the connecting rod 236 away from the moving plate 235. A positioning groove 238 is opened on the top of the L-shaped frame 213 below the mounting bracket 231, and the positioning rod 237 is inserted into the positioning groove 238.

[0062] Example 2: Figure 5 and Figure 7 As shown, when adjusting the rotational displacement of the reciprocating screw 215, before the moving seat 226 has moved to its limit distance, the connecting plate 234 first abuts against the L-shaped plate 254. Then, as the moving seat 226 continues to move, the mounting bracket 231 slides outside the sliding rod 232, compressing the return spring 233, which in turn drives the connecting rod 236 to rotate. The rotation of the connecting rod 236 pulls the positioning rod 237 upwards, causing the positioning rod 237 to disengage from the positioning groove 238. This causes the moving seat 226 to lose its limit position on the L-shaped frame 213. The movement of the L-shaped frame 213 will no longer drive the moving seat 226 to move. When the L-shaped frame 213 returns to its original position and the connecting plate 234 separates from the L-shaped plate 254, the positioning rod 237 will return to its original position under the action of the return spring 233. This allows the positioning rod 237 to insert into the positioning groove 238 to position the moving seat 226. This prevents the moving seat 226 from being unable to move together with the L-shaped frame 213 due to resistance after the rack 228 meshes with the rotating gear 223 when the connecting plate 234 is not in contact with the L-shaped plate 254, thus avoiding affecting the subsequent cable winding work.

[0063] The transport component 3 is positioned above the base 1;

[0064] The handling assembly 3 includes gantry frames 301 symmetrically mounted on the top of the base 1 above the placement frame 101, and a threaded rod 302 is rotatably connected between the two gantry frames 301 on one side. The threaded rod 302 is externally threaded to the handling frame 303. A winch 304 is provided on the top of the handling frame 303. A stepper motor 305 is fixedly mounted on the upper side of one gantry frame 301. The output end of the stepper motor 305 passes through one gantry frame 301 and is fixedly connected to the threaded rod 302. A crossbar 306 is slidably connected to the inner side of the handling frame 303. The two ends of the crossbar 306 are fixedly connected to the two gantry frames 301. A wire rope 307 is wound around the outer side of the winch 304.

[0065] A hook 308 is fixedly installed at the bottom end of the wire rope 307, and an installation plate 309 is fixedly installed on the outside of the wire rope 307 above the hook 308. Vertical rods 310 are symmetrically slidably connected inside the installation plate 309, and the top ends of the two vertical rods 310 are evenly connected to the conveying frame 303.

[0066] Example 3: Figures 1-2 and Figure 11 As shown, when handling the cable roll, the winch 304 can be started to unwind the wire rope 307, causing the hook 308 to descend, and the hanging rope 105 to be hooked on the hook 308. The winch 304 can then be started to wind up the wire rope 307, allowing the drum 102 to be lifted. During the upward movement of the hook 308, the mounting plate 309 can be moved, allowing the mounting plate 309 to slide on the vertical rod 310, preventing the wire rope 307 from swinging unexpectedly. Then, the stepper motor 305 can be started to rotate the threaded rod 302, which can move the handling frame 303. After the handling frame 303 moves to the appropriate position, the wire rope 307 can be unwound, causing the drum 102 to fall. The rotating ring 103 on the drum 102 can be placed in the placement slot 106. Multiple drums 102 can be placed through the placement frame 101. The base 1 facilitates the handling of the cable and reduces the swaying amplitude of the cable roll during handling, making it easier to place the cable roll later.

[0067] Working principle: When using this power transmission line cable handling device, firstly, according to... Figures 1-11As shown, during the cable winding process in the construction of the transmission line, the roller 102 is placed on two support plates 201, so that the rotating ring 103 is placed into the receiving groove 202. During placement, the connecting block 104 slides into the connecting groove 207 on the connecting seat 206. Then, one end of the cable can be wound around the roller 102 and passed through the two rollers 246. The screw 240 is rotated to move the movable plate 241 downward. After the movable plate 241 moves downward, the moving block 249 moves downward. After the moving block 249 moves downward, the connection between the movable block 248 and the movable groove 250 can drive the two adjusting frames 245 to move closer together, so that the two rollers 246 can clamp the cable. As the movable plate 241 moves downward, the connecting frame 251... The column 257 can be moved downwards. After the column 257 moves downwards, it slides in the sliding groove 256, which moves the guide block 255. This causes the L-shaped plate 254 to move closer to the L-shaped frame 213. The smaller the cable size, the greater the displacement of the L-shaped plate 254. Then, the servo motor 205 can be started to rotate, causing the roller 102 to rotate and wind up the cable. During the rotation of the roller 102, the turntable 208 can be rotated, causing the column block 209 on the turntable 208 to rotate circumferentially. The rotation of the column block 209 can drive the movable frame 210 to move back and forth through the sliding connection with the movable frame 210. This can drive the L-shaped frame 213 to move back and forth, causing the rack 228 to move and mesh with the rotating gear 223 to drive the connecting shaft 220. When the connecting shaft 220 rotates, it drives the ratchet 221 to rotate. At this time, the ratchet 221 and the ratchet tooth 222 pull the rotating seat 218 to rotate, which in turn drives the reciprocating screw 215 to rotate, thereby driving the movable seat 216 to move. When the L-shaped frame 213 moves to its reset position, the rotating gear 223 rotates in the opposite direction and will no longer drive the reciprocating screw 215 to rotate to its reset position. In the initial state of the L-shaped plate 254, one reciprocating movement of the movable frame 210 can cause the reciprocating screw 215 to rotate one revolution, which in turn causes the roller 102 to rotate one revolution, thus driving the reciprocating screw 215 to rotate one revolution. When winding up small cables, the L-shaped plate 254 moves closer to the L-shaped frame 213, and before the movable frame 210 has moved to its farthest distance... The movement of the movable seat 226 can be blocked and limited by the L-shaped plate 254. At this time, the L-shaped frame 213 continues to move, which allows the movable rod 225 to slide on the fixed block 224 and stretch the telescopic spring 227. At this time, the rack 228 no longer moves, and thus will not drive the reciprocating screw 215 to rotate. This allows the rotation position of the reciprocating screw 215 to be shortened when the roller 102 rotates once when winding up thinner cables, thereby reducing the displacement of the movable seat 216. This allows the cable to be wound up once after the roller 102 rotates once. At the same time, the cable can be intermittently wound through the two rollers 246. During the reciprocating winding process, the position of the movable seat 216 can be adjusted adaptively according to the size of the cable.

[0068] When adjusting the rotational displacement of the reciprocating screw 215, before the movable seat 226 has moved to its limit distance, the connecting plate 234 first abuts against the L-shaped plate 254. Then, as the movable seat 226 continues to move, the mounting bracket 231 slides outside the sliding rod 232, compressing the return spring 233, which drives the connecting rod 236 to rotate. The rotation of the connecting rod 236 pulls the positioning rod 237 upwards, causing it to disengage from the positioning groove 238. This causes the movable seat 226 to lose its limit position on the L-shaped frame 213. Afterwards, the movement of the L-shaped frame 213 will no longer drive the movable seat 226 to move. When the L-shaped frame 213 returns to its original position and the connecting plate 234 separates from the L-shaped plate 254, the return spring 233 causes the positioning rod 237 to return to its original position, allowing it to insert into the positioning groove 238 to position the movable seat 226. When transporting the cable reel, the winch 304 can be started to unwind the wire rope 307, causing the hook 308 to descend. The hanging rope 105 is then hooked onto the hook 308. The winch 304 is then started to wind up the wire rope 307, which can lift the drum 102. During the upward movement of the hook 308, the mounting plate 309 can be moved, allowing the mounting plate 309 to slide on the vertical rod 310, preventing the wire rope 307 from swinging unexpectedly. Then, the stepper motor 305 can be started to rotate the threaded rod 302, which can move the transport frame 303. After the transport frame 303 moves to the appropriate position, the wire rope 307 can be unwound, causing the drum 102 to fall. The rotating ring 103 on the drum 102 can be placed in the placement slot 106. Multiple drums 102 can be placed using the placement frame 101.
