[0054] The following further describes the present utility model in detail with reference to the drawings.

[0055] Please refer to Figure 1, a collaborative maintenance robot provided by an embodiment of the present invention, includes a climbing device 100, a load device 200, a repair device 300, and one or more traction devices 400. Among them, the climbing device 100 includes a first frame 110, a first clamping mechanism 120, and a climbing driving mechanism 130. The first clamping mechanism 120 is disposed on the first frame 110 and is used for clamping the cable 10. A plurality of climbing driving mechanisms 130 are provided and are located around the cable 10. Each climbing driving mechanism 130 is disposed on the first frame 110 and is used for actively crawling along the cable 10. The load device 200 includes a second frame 210, a second clamping mechanism 220, and a climbing driven mechanism 230. The second clamping mechanism 220 is disposed on the second frame 210 and is used for clamping the cable 10. A plurality of climbing driven mechanisms 230 are provided and are located around the cable 10. Each climbing driven mechanism 230 is disposed on the first frame 110 and is used for moving along the cable 10. The repair device 300 is disposed on the second frame 210 and is used for repairing the cable 10. One or more traction devices 400 include a winch 410 and a traction rope 420. The winch 410 is used for winding the traction rope 420. Among them, one of the winch 410 and the traction rope 420 is connected to the first frame 110, and the other is connected to the second frame 210. When the first clamping mechanism 120 clamps the cable 10, the second clamping mechanism 220 does not clamp the cable 10, and the winch 410 winds the traction rope 420 to make the load device 200 move along the cable 10 toward the climbing device 100. When the first clamping mechanism 120 does not clamp the cable 10, the second clamping mechanism 220 clamps the cable 10, the climbing driving mechanism 130 crawls along the cable 10, and the winch 410 pays out the traction rope 420.

[0056] Among them, one or more traction devices 400 are provided. If a plurality of traction devices 400 are provided, the plurality of traction devices 400 are distributed around the cable 10.

[0057] Specifically, in the first climbing stage, the first clamping mechanism 120 is not in a clamped state with respect to the cable 10, and the second clamping mechanism 220 is in a clamped state with respect to the cable 10, that is, the load device 200 is fixed with respect to the cable 10. The climbing driving mechanism 130 crawls forward along the extending direction of the cable 10. Correspondingly, the climbing device 100 crawls forward along the extending direction of the cable 10. Among them, the winch 410 pays out the towing rope 420 to satisfy the forward crawling of the climbing device 100. In the second climbing stage, the first clamping mechanism 120 is in a clamped state with respect to the cable 10, that is, the climbing device 100 is fixed with respect to the cable 10, and the second clamping mechanism 220 is not in a clamped state with respect to the cable 10. The winch 410 winds up the towing rope 420. Correspondingly, the climbing device 100 pulls the load device 200 forward through the towing rope 420, and the climbing driven mechanism 230 moves forward along the cable 10, and the repair device 300 moves forward synchronously with the load device 200, so as to repair the cable 10. By circulating the above first climbing stage and the second climbing stage, the cooperative maintenance machine gradually crawls along the extending direction of the cable 10, and the repair device 300 gradually repairs the cable 10.

[0058] It can be understood that during the forward crawling process of the climbing device 100, the load device 200 is fixed with respect to the cable 10 by using the second clamping mechanism 220. Thus, the climbing device 100 does not need to bear the weights of the load device 200 and the repair device 300. The climbing device 100 can stably crawl forward along the cable 10 without the risk of falling off. Similarly, during the forward crawling process of the load device 200, the climbing device 100 is fixed with respect to the cable 10 by using the first clamping mechanism 120. Thus, the climbing device 100 can stably pull the load device 200 and the repair device 300 forward through the towing rope 420 to satisfy that the load device 200 can carry the relatively heavy repair device 300, so as to meet the functional requirements of the repair device 300.

[0059] In addition, the load device 200 only uses the winch 410 to wind up the towing rope 420, thereby pulling the load device 200 and the repair device 300 to crawl forward along the cable 10. It can be seen that the overall structure of the cooperative maintenance robot is simple, the manufacturing cost is low, and it is convenient for the climbing device 100 and the load device 200 to perform repairs separately.

[0060] In some embodiments, referring to Figure 1 , the winch 410 is connected to the second frame 210, and the towing rope 420 is connected to the first frame 110. More precisely, the palm of the first clamping mechanism 120 is provided with a lug 1211, and the towing rope 420 is connected to the lug 1211 to be connected to the first frame 110.

[0061] It can be understood that the winch 410 is arranged on the load device 200. When the climbing device 100 crawls forward along the cable 10, the climbing device 100 does not need to bear the weight of the winch 410, so as to ensure that the climbing driving mechanism 130 of the climbing device 100 can crawl forward stably along the cable 10 without the risk of falling off.

[0062] Of course, the winch 410 can also be arranged on the first frame 110, and the towing rope 420 is connected to the second frame 210.

[0063] In some embodiments, referring to Figure 1 And Figure 2 , the winch 410 includes a mounting base 411, a power component 412, a reel 413 and an encoder 414. Among them, the mounting base 411 is arranged on the first frame 110 or the second frame 210, the reel 413 is rotatably arranged on the mounting base 411, and the towing rope 420 is used to wind around the reel 413. The power component 412 can adopt a servo motor. The power component 412 is horizontally fixedly connected to the mounting base 411, and the drive shaft of the power component 412 is in transmission connection with one end of the rotating shaft of the reel 413 through a transmission belt. Thus, the power component 412 drives the reel 413 to rotate, so as to wind or unwind the towing rope 420. The encoder 414 is connected to the other end of the rotating shaft of the reel 413, and is used to detect the rotation condition of the reel 413, so as to determine the winding condition of the reel 413 for the towing rope 420, and further determine the rising height of the repair device 300, so as to facilitate the repair device 300 to accurately repair the surface of the cable 10.

[0064] Furthermore, the winch 410 further includes a transmission lead screw 415, a wire guide seat 416 and a transmission assembly 417. Among them, the transmission lead screw 415 is arranged on one side of the reel 413 and is rotatably connected to the mounting base 411, and the central axis of the transmission lead screw 415 is arranged parallel to the rotating shaft of the reel 413. One end of the transmission lead screw 415 is in transmission connection with the rotating shaft of the reel 413 through the transmission assembly 417, where the transmission assembly 417 can be a gear assembly or a transmission belt assembly. The wire guide seat 416 is slidably arranged on the mounting base 411 and is in threaded connection with the transmission lead screw 415. The wire guide seat 416 is provided with a wire guide hole 4161, and the towing rope 420 passes through the wire guide hole 4161 to wind around the wire guide seat 416, and the power component 412 drives the transmission lead screw 415 to rotate through the transmission assembly 417.

[0065] Specifically, the power member 412 drives the reel 413 to rotate, and the reel 413 winds up the towing rope 420; at the same time, the power member 412 drives the transmission lead screw 415 to rotate through the transmission assembly 417, and the transmission lead screw 415 drives the wire seat 416 to slide along its axial direction, so that the towing rope 420 is gradually wound from one end of the reel 413 to the other end of the reel 413, thereby ensuring that the winch 410 winds up the towing rope 420 neatly.

[0066] Of course, compared with sharing a single power member 412, another power member 412 can also be used to drive the transmission lead screw 415 to rotate to drive the wire seat 416 to slide.

[0067] In some embodiments, referring to Figure 3 and Figure 4 , a plurality of climbing active mechanisms 130 are provided and distributed around the cable 10. Each climbing active mechanism 130 includes a first roller assembly 131 and a second roller assembly 132. Among them, the first roller assembly 131 includes a first bracket 1311, a first roller 1312 and a driving member 1313. The first bracket 1311 is rotatably connected to the first frame 110, the first roller 1312 is rotatably arranged on the first bracket 1311, and the first roller 1312 is rotationally adjusted through the first bracket 1311 to tightly press on the cable 10. The driving member 1313 is a servo motor, and the driving member 1313 is arranged on the first bracket 1311 for driving the first roller 1312 to rotate; the second roller assembly 132 includes a second bracket 1321, a second roller 1322 and a damper 1323. The second bracket 1321 is rotatably connected to the first frame 110, the second roller 1322 is rotatably arranged on the second bracket 1321, the second roller 1322 is rotationally adjusted through the second bracket 1321 to tightly press on the cable 10, and the damper 1323 is arranged on the second bracket 1321 for damping the reverse rotation of the second roller 1322. Of course, one of the dampers 1323 can also be replaced with an encoder for detecting the rolling condition of the corresponding second roller 1322, so as to determine the upward climbing distance of the climbing device 100.

[0068] Specifically, the first roller 1312 is tightly pressed against the side wall of the cable 10 through the rotation of the first bracket 1311. The driving member 1313 drives the first roller 1312 to rotate, and the first roller 1312 rolls forward along the cable 10, so that the climbing device 100 crawls forward along the cable 10. At the same time, the second roller 1322 is tightly pressed against the side wall of the cable 10 through the rotation of the second bracket 1321, and the second roller 1322 rolls forward along the cable 10 synchronously with the first roller 1312. When the driving member 1313 malfunctions, the damper 1323 restricts the reverse resistance of the second roller 1322, thereby providing a large enough frictional resistance for the climbing device 100 to prevent the climbing device 100 from falling quickly.

[0069] Further, the climbing active mechanism 130 further includes a first diameter-changing adjusting component 133 for simultaneously adjusting the pressing forces of the first roller 1312 and the second roller 1322 on the cable 10. Specifically, the first diameter-changing adjusting component 133 includes a first adjusting screw rod 1331, a first adjusting seat 1332, a first connecting rod 1334, a first shock absorber 1335, a second connecting rod 1336 and a second shock absorber 1337. Among them, the first adjusting screw rod 1331 is rotatably connected to the first frame 110, and the rotation axis of the first adjusting screw rod 1331 is vertically arranged with respect to the rotation axis of the first bracket 1311. More precisely, the first adjusting screw rod 1331 is substantially perpendicular to the cable 10. A first operation handle 1333 is provided at the outer end of the first adjusting screw rod 1331 to facilitate the staff to rotate and adjust the first adjusting screw rod 1331; the first adjusting seat 1332 is threadedly connected to the first adjusting screw rod 1331. One end of the first connecting rod 1334 is rotatably connected to the upper end of the first adjusting seat 1332, one end of the first shock absorber 1335 is fixedly connected to the other end of the first connecting rod 1334, and the other end of the first shock absorber 1335 is rotatably connected to the middle position of the first bracket 1311. Similarly, one end of the second connecting rod 1336 is rotatably connected to the lower end of the first adjusting seat 1332, and the first connecting rod 1334 and the second connecting rod 1336 are symmetrically arranged with respect to the first adjusting screw rod 1331; one end of the second shock absorber 1337 is fixedly connected to the other end of the second connecting rod 1336, and the other end of the second shock absorber 1337 is rotatably connected to the middle position of the second bracket 1321. The first shock absorber 1335 and the second shock absorber 1337 are symmetrically arranged with respect to the first adjusting screw rod 1331.

[0070] Specifically, when it is necessary to adjust the pressing force of the first roller 1312 and the second roller 1322 on the cable 10, the operator rotates the first adjusting screw rod 1331 through the first operation handle 1333. The first adjusting screw rod 1331 drives the first adjusting seat 1332 to move away from the cable 10. The first adjusting seat 1332 pushes the first bracket 1311 to rotate towards the cable 10 through the first connecting rod 1334 and the first shock absorber 1335, so that the first roller 1312 is tightly pressed on the cable 10. Synchronously, the first adjusting seat 1332 pushes the second bracket 1321 to rotate towards the cable 10 through the second connecting rod 1336 and the second shock absorber 1337, so that the second roller 1322 is tightly pressed on the cable 10. Among them, the first connecting rod 1334 acts on the first bracket 1311 through the first shock absorber 1335. The first shock absorber 1335 has a buffering effect on the first roller 1312, thus avoiding the first roller 1312 from being overly pressed on the cable 10, and further enabling the first roller 1312 to have an obstacle avoidance effect. Similarly, the second connecting rod 1336 acts on the second bracket 1321 through the second shock absorber 1337. The second shock absorber 1337 has a buffering effect on the second roller 1322, thus avoiding the second roller 1322 from being overly pressed on the cable 10, and further enabling the second roller 1322 to have an obstacle avoidance effect.

[0071] In some embodiments, referring to Figure 3 and Figure 5 , the first clamping mechanism 120 includes two first clamping members 121 and a first driving module 122. Among them, the two first clamping members 121 are rotatably arranged on the first frame 110 around a vertical axis. The first driving module 122 is connected to the two first clamping members 121 to drive the two first clamping members 121 to clamp on the cable 10, so that the climbing device 100 is fixed on the cable 10.

[0072] In some embodiments, referring to Figure 6 and Figure 7, the climbing driven mechanism 230 includes a mounting bracket 231 and one or more roller assemblies 232. For example, the climbing driven mechanism 230 is provided with two roller assemblies 232, which are respectively arranged at the upper and lower ends of the mounting bracket 231. Among them, the mounting bracket 231 is vertically arranged on the second frame 210. Each roller assembly 232 includes a second adjusting seat 2321, a third bracket 2322, a third roller 2323 and an elastic member 2324. Among them, the second adjusting seat 2321 is adjustably arranged on the mounting bracket 231 along the direction perpendicular to the cable 10, the third bracket 2322 is adjustably arranged on the second adjusting seat 2321 along the direction perpendicular to the cable 10, the elastic member 2324 abuts against the second adjusting seat 2321 and the third bracket 2322, the third roller 2323 is rotatably connected to the third bracket 2322, and the elastic member 2324 is used to keep the third roller 2323 pressed against the cable 10.

[0073] It can be understood that the second adjusting seat 2321 is adjusted in the direction towards the cable 10, so that the third roller 2323 is firmly pressed against the cable 10, and the third roller 2323 crawls forward along the cable 10 to ensure that the load device 200 crawls forward stably along the cable 10. It can be understood that the elastic member 2324 presses the third roller 2323 against the cable 10 along the direction perpendicular to the cable 10. Compared with the first roller 1312 and the second roller 1322 rotating and pressing against the cable 10, the frictional resistance between the third roller 2323 and the cable 10 during the crawling process is effectively reduced, so as to ensure that the climbing device 100 can smoothly pull the load device 200 upward by the winding of the towing rope 420.

[0074] Furthermore, the climbing driven mechanism 230 further includes a second diameter-changing adjusting assembly 233. The second diameter-changing adjusting assembly 233 is arranged on the mounting bracket 231 and is connected to the second adjusting seats 2321 of the respective roller assemblies 232, and is used to synchronously adjust the second adjusting seats 2321 in the direction towards the cable 10 so that the third rollers 2323 are firmly pressed against the cable 10.

[0075] Specifically, the second diameter-changing adjustment component 233 includes a rotating rod 2331 and a linkage component 2332. The rotating rod 2331 is rotatably connected to the mounting bracket 231. A second control handle 2335 is provided at the top of the rotating rod 2331. Each linkage component 2332 is connected to the rotating rod 2331. At the same time, the linkage components 2332 are provided in the same number as the roller components 232, and the two are connected one by one. Among them, the linkage component 2332 includes a second adjustment screw rod 2333 and a linkage structure 2334. The second adjustment screw rod 2333 is rotatably connected to the mounting bracket 231. The second adjustment seat 2321 is threadedly connected to the second adjustment screw rod 2333. The linkage structure 2334 is drivingly connected to the rotating rod 2331 and the second adjustment screw rod 2333. The rotating rod 2331 drives the second adjustment screw rod 2333 to rotate through the linkage structure 2334. Among them, the linkage structure 2334 can be a worm and gear structure or a gear assembly, which is not limited in this application.

[0076] During the specific working process, the staff manipulates the rotating rod 2331 to rotate through the second control handle 2335. The rotating rod 2331 drives each second adjustment screw rod 2333 to rotate through the linkage structure 2334. Each second adjustment screw rod 2333 drives the second adjustment seat 2321 to move towards the cable 10, so that the third roller 2323 is firmly pressed against the cable 10.

[0077] In some embodiments, referring to Figure 6 and Figure 8 , the second clamping mechanism 220 includes two second clamping members 221 and a second driving module 222. Among them, the two second clamping members 221 are rotatably arranged on the second frame 210 around a vertical axis. The second driving module 222 is connected to the two second clamping members 221 to drive the two second clamping members 221 to clamp on the cable 10, so as to fix the load device 200 on the cable 10.

[0078] In some embodiments, referring to Figure 6 , Figure 9 and Figure 10 , the repair device 300 includes a multi-axis robotic arm 310 and an execution end 320. Among them, the end of the multi-axis robotic arm 310 has a driving module 311. The execution end 320 includes a mounting chassis 321 and a plurality of execution modules. Among them, the driving module 311 is connected to the mounting chassis 321. The plurality of execution modules are arranged in sequence around the mounting chassis 321. The driving module 311 is used to drive the mounting chassis 321 to rotate so as to be able to switch the execution modules.

[0079] It can be understood that when the repair device 300 repairs the cable 10, the multi-axis robotic arm 310 can adjust the position of the execution end 320 with multiple degrees of freedom, so that the execution end 320 is aligned with the cable 10. At the same time, the driving module 311 drives the installation chassis 321 to rotate, and the execution module of the installation chassis 321 can be switched to the working position to be able to grind, clean, repair, etc. the cable 10.

[0080] Furthermore, there are multiple execution modules, which are respectively a monitoring camera 322, a three-dimensional scanning camera 323, a grinding mechanism 324, a rotary cleaning mechanism 325, a pneumatic cleaning mechanism 326 and a repair mechanism 327.

[0081] Specifically, in the first stage, the three-dimensional scanning camera 323 consists of structured light + high-resolution color cameras. It performs three-dimensional reconstruction on the cable 10 according to the defect position, type and other information detected by the detection camera 140 on the climbing device 100 by using the structured light + high-resolution color camera method, obtains the size information of the defect, and feeds it back to the control system to guide its automatic repair operation. In the second stage, the grinding mechanism 324 uses a high-speed grinder + grinding head to grind the surface of the cable 10. In the third stage, the rotary cleaning mechanism uses a high-speed grinder + cleaning head to clean the cable 10. In the fourth stage, the pneumatic cleaning mechanism 326 uses an air pump to generate high-pressure air flow to blow and clean the cable 10. In the fifth stage, the repair mechanism 327 repairs the defect with raw materials identical to the original PE sheath material, and finally grinds and polishes the repaired part. Among them, the monitoring camera 322 is used to detect the whole process of grinding, cleaning and repairing in real time, so as to facilitate the staff to check the repair situation of the cable.

[0082] Even further, referring to Figure 9 and Figure 10 , the repair mechanism 327 includes a repair body 3271, a feeding motor 3272, a heating module 3273 and a heat dissipation module 3274. Among them, the base of the repair body 3271 is arranged on the installation chassis 321, the tail of the repair body 3271 has a feeding inlet 32711, and the head of the repair body 3271 has a repair nozzle 32712. The feeding motor 3272 is arranged on one side of the repair body 3271 and is used to feed the repair material into the repair body 3271 from the feeding inlet 32711. The heating module 3273 is arranged at the repair nozzle 32712 of the repair body 3271 and is used to heat the repair material in the repair body 3271. The heat dissipation module 3274 is arranged on the side of the repair body 3271 and is used to dissipate heat from the repair body 3271.

[0083] Specifically, the feeding motor 3272 inputs the repair material from the feeding inlet 32711 into the repair nozzle 32712 of the repair body 3271, thereby conveying the repair material to the position of the heating module 3273. The heating module 3273 heats the repair nozzle 32712, and the repair material in the repair nozzle 32712 melts into a molten state. The molten repair material is applied to the defective position of the cable 10 through the repair nozzle 32712, thereby repairing the cable 10. And during this process, the repair mechanism 327 continuously feeds the cable 10 until the defect repair is completed. The entire repair process is automatically completed by the control system controlling the multi-axis robotic arm 310.

[0084] In some embodiments, referring to Figure 1 , the climbing device 100 further includes a detection camera 140. The detection camera 140 is disposed on the first frame 110. More precisely, the detection camera 140 is disposed on the first bracket 1311. The detection camera 140 is used to detect the defects of the cable 10, and the repair device 300 repairs the defects of the cable 10 based on the detection results of the detection camera 140. Of course, the detection camera 140 can also be disposed on the load device 200.

[0085] It can be understood that the detection camera 140 is disposed on the climbing device 100. The climbing device 100 completes climbing before the load device 200, and then the load device 200 climbs. The inspection device moves forward synchronously with the load device 200. Thus, it can be seen that the detection camera 140 can pre-detect the defect condition of the cable 10 to determine the repair method of the cable 10, so as to ensure that the repair device 300 can effectively and quickly repair the cable 10 during the crawling process.
