Description

Technical Field

[0001] This application relates to the field of power grid equipment maintenance technology, specifically to a climbing assistance system. Background Technology

[0002] With the development of power technology, power distribution networks have become increasingly complex. To save space and costs, it is common for multiple lines to share a single tower. While this "multi-line, shared tower" layout has significant advantages in improving land utilization and reducing the number of towers, it also presents challenges for maintenance work. In particular, when workers climb the towers to perform line maintenance or repairs, they must strictly adhere to safety regulations and alternate between using safety ropes and safety harnesses to ensure that at least one of them is securely fastened to the tower at all times, preventing falls during high-altitude operations.

[0003] This operation is cumbersome and time-consuming, greatly reducing work efficiency. Moreover, more complex situations may arise in actual pole climbing operations, such as the presence of equipment like cabinets on the pole. These additional obstacles further increase the difficulty of alternating the use of safety ropes, making it more inconvenient for workers to operate in confined spaces. This not only affects work efficiency but also increases the risk of accidents. Summary of the Invention

[0004] This application mainly provides a climbing assistance system that can improve the safety and efficiency of pole climbing operations.

[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution: A climbing assistance system is provided, including a rope-hanging device and a fall protection device. The rope-hanging device includes a U-shaped frame and a crossbar. The crossbar includes a first end and a second end, which are detachably connected to the two sides of the opening of the U-shaped frame. The first end can rotate upward about the second end as an axis, and the second end can rotate downward about the first end as an axis. The first end is used to connect a safety rope. The fall protection device includes a movable control rod, a first pin, a second pin, a rope-pressing component, and a housing. The housing has a receiving groove along a first direction for the safety rope to pass through. The first pin is connected to one end of the housing and the second pin parallel to the first direction. The other end of the second pin passes through the rope-pressing component along a second direction perpendicular to the first direction. The receiving groove has a first docking notch on its side wall away from the first pin. The movable control rod is provided corresponding to the first docking notch and is used to open or close the first docking notch. The second pin can rotate into the first docking notch. The rope-pressing component is used to connect a safety belt. The movable control lever is movably connected to the housing and can move relative to the housing between a first position and a second position. When the movable control lever is in the second position, it limits the second pin to the first docking notch, and the rope pressing member can limit the safety rope to the receiving groove.

[0006] In one specific embodiment, the housing is provided with a movable slot parallel to the first direction. The movable slot includes a first slot segment and a second slot segment. The first slot segment and the second slot segment are respectively disposed on both sides of the opening of the first docking notch. When the movable control rod is in the second position, the movable control rod is simultaneously disposed in the first slot segment and the second slot segment, closing the opening of the first docking notch.

[0007] In one specific embodiment, the fall arrestor further includes a spring, one end of which is connected to a movable control rod and the other end of which is connected to the inner wall of the movable slot. When the movable control rod moves from the second position to the first position, the spring deforms.

[0008] In one specific embodiment, the movable control lever includes a first actuating lever and a moving lever. The side wall of the first groove segment is provided with a movable through groove. The first actuating lever is disposed at one end of the moving lever. The moving lever is disposed within the first groove segment. The first actuating lever is exposed through the movable through groove. The first actuating lever can move parallel to the first direction within the movable through groove.

[0009] In one specific embodiment, the movable channel includes a third channel segment and a fourth channel segment. The end of the third channel segment away from the second channel segment is connected to the fourth channel segment. The first actuating lever can rotate about the moving rod as an axis to switch from the third channel segment to the fourth channel segment. When the first actuating lever is located in the third channel segment, part of the moving rod is inserted in the second channel segment.

[0010] In one specific embodiment, the fall arrestor further includes a safety switch, which includes a first torsion spring, a third pin, and a second actuating rod. The third pin is connected to the housing and the second actuating rod in parallel to the first direction. The first torsion spring is sleeved on the third pin and abuts against the housing and the second actuating rod. Under the abutment of the first torsion spring, the second actuating rod is limited to the end of the third groove segment away from the fourth groove segment.

[0011] In one specific embodiment, the fall arrestor further includes a second torsion spring, one end of which is connected to the rope pressing member and the other end of which is connected to the end of the second pin that passes through the first pin. When the rope pressing member rotates about the second pin to lock the safety rope into the receiving groove, the second torsion spring deforms.

[0012] In one specific embodiment, the rope pressing member includes a limiting rod. The rope pressing member swings between a third position and a fourth position relative to the receiving groove, with the second pin as the axis. When the rope pressing member is in the third position and the fourth position, the limiting rod abuts against the housing.

[0013] In one specific embodiment, the crossbar includes a fourth pin and a fifth pin. The fourth pin is disposed at the first end, and the fifth pin is disposed at the second end. The extension direction of the fourth pin is parallel to the extension direction of the fifth pin and perpendicular to the extension direction of the crossbar. The U-shaped frame has a third end and a fourth end on both sides of the opening. The third end has a second mating notch that mates with the fourth pin. The fourth end has a third mating notch that mates with the fifth pin. The second mating notch faces upward, and the third mating notch faces downward.

[0014] In one specific embodiment, the rope-hanging device further includes an operating rod connected to the side of the U-shaped frame opposite to the crossbar, and the length of the operating rod is variable.

[0015] The beneficial effects of this application are as follows: Unlike existing technologies, in the embodiment of this application, the flexible crossbar at both ends can work with the U-shaped frame to smoothly suspend the safety rope to a height such as a pole or tower. Workers can secure the safety rope without climbing the pole, greatly improving the safety of pole climbing operations. Simultaneously, the fall arrestor can secure the safety belt and safety rope attached to the worker, solving the problem of frequent switching between safety belts and safety ropes. The fall arrestor and the rope-hanging device work together to effectively ensure the safety of on-site workers, reduce the amount of work and steps, and greatly improve the safety and efficiency of pole climbing operations.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application.

[0031] With the development of power technology, power distribution networks have become increasingly complex. To save space and costs, it is common for multiple lines to share a single tower. While this "multi-line, shared tower" layout has significant advantages in improving land utilization and reducing the number of towers, it also presents challenges for maintenance work. In particular, when workers climb the towers to perform line maintenance or repairs, they must strictly adhere to safety regulations and alternate between using safety ropes and safety harnesses to ensure that at least one of them is securely fastened to the tower at all times, preventing falls during high-altitude operations.

[0032] This operation is cumbersome and time-consuming, greatly reducing work efficiency. Moreover, more complex situations may arise in actual pole climbing operations, such as the presence of equipment like cabinets on the pole. These additional obstacles further increase the difficulty of alternating the use of safety ropes, making it more inconvenient for workers to operate in confined spaces. This not only affects work efficiency but also increases the risk of accidents.

[0033] In order to improve or solve the above technical problems, the inventors of this application, after long-term research, have proposed at least the following embodiments.

[0034] See Figures 1 to 10 , Figure 1 This is a schematic diagram of an embodiment of the climbing assistance system provided in this application.

Figure 8 yes Figure 7 A cross-sectional structural schematic diagram of one embodiment of the fall arrestor shown. Figure 9 This is a structural diagram of the fall arrest device and safety rope provided in this application before assembly. Figure 10 This is a cross-sectional view of the fall protection device provided in this application from another angle. A specific embodiment of this application provides a climbing assistance system 1, including a rope attachment device 2 and a fall protection device 3.

[0035] The rope-hanging device 2 may include a U-shaped frame 21 and a crossbar 22. The crossbar 22 includes a first end 221 and a second end 224, which are detachably connected to the two sides of the opening of the U-shaped frame 21. The first end 221 can rotate upward about the second end 224, and the second end 224 can rotate downward about the first end 221. The first end 221 is used to connect the safety rope 4.

[0036] like Figure 1As shown, the rope-hanging device 2 can be used to suspend the safety rope 4 onto the crossarm 61 of the tower 6. During the suspension process, the ground worker can first use the crossbar 22 to press against the lower surface of the crossarm 61. At this time, the worker can release the control of the safety rope 4, causing the crossbar 22 to rotate downwards around its first end 221 under the action of the crossbar 22, allowing the crossarm 61 to smoothly pass through the opening of the U-shaped frame 21 and enter the opening of the U-shaped frame 21. After the crossarm 61 enters, the worker can pull the safety rope 4, causing the crossbar 22 to rotate upwards around its first end 221 under the action of the safety rope 4, so that the second end 224 is again connected with the opening of the U-shaped frame 21, confining the crossarm 61 between the U-shaped frame 21 and the crossbar 22. Then, the workers can pull the U-shaped frame 21 downwards. Under the action of the crossbeam 61, the first end 221 of the crossbar 22 rotates upwards with the second end 224 as the axis, so that a gap appears between the first end 221 and the U-shaped frame 21. The crossbeam 61 can be withdrawn through the gap, and the safety rope 4 can be hung on the crossbeam 61 as the U-shaped frame 21 moves downwards, so as to achieve the purpose of the workers setting the safety rope 4 at a high place.

[0037] The fall arrestor 3 includes a movable control lever 31, a first pin 32, a second pin 33, a rope-pressing component 34, and a housing 35. The housing 35 has a receiving groove 351 along a first direction X, for the passage of a safety rope 4. The first pin 32 is connected to one end of the housing 35 and the second pin 33, parallel to the first direction X. The other end of the second pin 33 passes through the rope-pressing component 34 along a second direction Y, perpendicular to the first direction X. A first mating notch 352 is provided on the side wall of the receiving groove 351 away from the first pin 32. The movable control lever 31 is positioned corresponding to the first mating notch 352 and can be used to open or close the first mating notch 352. The second pin 33 can be rotated into the first mating notch 352. The rope-pressing component 34 can be used to connect a safety belt 5.

[0038] When the worker is performing normal operations and no fall occurs, there is sufficient space between the rope-pressing component 34 and the receiving groove 351 to allow the safety rope 4 to move freely relative to the rope-pressing component 34. In the event of a fall, the rope-pressing component 34 is pulled by the safety belt 5, causing it to rotate around the second pin 33 until it presses against the rope and the bottom of the receiving groove 351, thereby fixing the fall arrest component to a certain position on the safety rope 4, thus stopping the worker's fall and achieving the fall prevention effect.

[0039] The movable control lever 31 is movably connected to the housing 35. The movable control lever 31 can move relative to the housing 35 between the first position A and the second position B. When the movable control lever 31 is in the second position B, the movable control lever 31 limits the second pin 33 in the first docking notch 352, and the rope pressing member 34 can limit the safety rope 4 in the receiving groove 351.

[0040] In this embodiment, the flexible crossbar 22 at both ends, in conjunction with the U-shaped frame 21, allows the safety rope 4 to be easily suspended to a height such as the tower 6. Workers can secure the safety rope 4 without climbing the tower 6, significantly improving the safety of pole climbing operations. Simultaneously, the fall arrestor 3 secures the safety belt 5 attached to the worker to the safety rope 4, solving the problem of frequent switching between the safety belt 5 and the safety rope 4. The fall arrestor 3 and the rope-hanging device 2 work together to effectively ensure the safety of on-site workers, reduce the amount of work and steps, and greatly improve the safety and efficiency of pole climbing operations.

[0041] Specifically, the first end 221 may be provided with a first connecting buckle 227, and the crossbar 22 is connected to one end of the safety rope 4 through the first connecting buckle 227. The end of the rope pressing member 34 facing away from the receiving groove 351 may be provided with a second connecting buckle 342, and the rope pressing member 34 is connected to the safety belt 5 through the second connecting buckle 342.

[0042] like Figure 9 , Figure 10 As shown, the end of the rope-pressing component 34 facing the receiving groove 351 may be provided with a fixed inclined groove 343. Since the safety rope 4 is vertically arranged under the action of gravity, the fall arrestor connected to the safety rope 4 is also vertically arranged. Due to the presence of the fixed inclined groove 343, the distance between the end of the rope-pressing component 34 facing the receiving groove 351 and the bottom of the receiving groove 351 decreases as the height decreases.

[0043] When the worker is performing normal operations and no fall occurs, the rope-pressing component 34 can rotate around the second pin 33 until the fixed inclined groove 343 is parallel to the first direction X, providing sufficient space between the rope-pressing component 34 and the receiving groove 351 for the safety rope 4 to move freely relative to the rope-pressing component 34. In the event of a fall, the rope-pressing component 34 is pulled by the safety belt 5, causing it to rotate around the second pin 33 until it presses against the rope and the bottom of the receiving groove 351, thereby fixing the fall arrest component to a certain position on the safety rope 4, thus stopping the worker's fall and achieving the fall prevention effect.

[0044] In one specific embodiment of this application, the housing 35 may be provided with a movable slot 353 parallel to the first direction X. The movable slot 353 includes a first groove segment 354 and a second groove segment 358, which are respectively disposed on both sides of the opening of the first docking notch 352. When the movable control lever 31 is in the second position B, the movable control lever 31 is simultaneously disposed in the first groove segment 354 and the second groove segment 358, thereby closing the opening of the first docking notch 352.

[0045] The structure provided in this embodiment allows for the control of the opening and closing of the first mating notch 352 by utilizing the connection relationship between the movable control rod 31 and the first groove segment 354 and the second groove segment 358, thereby effectively controlling whether the second pin 33 is limited.

[0046] In one specific embodiment of this application, the fall arrestor 3 further includes a spring 37. One end of the spring 37 can be connected to the movable control rod 31, and the other end is connected to the inner wall of the movable slot 353. When the movable control rod 31 moves from the second position B to the first position A, the spring 37 deforms. In the absence of external force, the movable control rod 31 can automatically close the first docking notch 352 under the elastic action of the spring 37, thereby reducing the probability that the second pin 33 will accidentally fall out of the first docking notch 352, causing the safety rope 4 to loosen from the fall arrestor assembly and creating a safety hazard, thus improving the safety of the fall arrestor 3.

[0047] In one specific embodiment of this application, the movable control lever 31 may include a first actuating lever 311 and a moving lever 312. A movable through-slot 355 is provided on the side wall of the first groove segment 354. The first actuating lever 311 is disposed at one end of the moving lever 312, and the moving lever 312 is disposed within the first groove segment 354. The first actuating lever 311 can be exposed through the movable through-slot 355 and can move parallel to the first direction X within the movable through-slot 355.

[0048] With the structure provided in this embodiment, the operator can use the exposed first actuating rod 311 to drive the moving rod 312 to move, thereby opening or closing the first docking notch 352. This can reduce the complexity of high-altitude operations. The cooperation between the first actuating rod 311 and the moving rod 312 can effectively improve the availability of the fall protection device 3 and even the climbing assistance system 1.

[0049] In one specific embodiment of this application, such as Figure 7 As shown, the movable through slot 355 may specifically include a third slot segment 356 and a fourth slot segment 357. The end of the third slot segment 356 away from the second slot segment 358 is connected to the fourth slot segment 357. The first actuating lever 311 can rotate about the moving lever 312 as an axis to switch from the third slot segment 356 to the fourth slot segment 357. When the first actuating lever 311 is located in the third slot segment 356, part of the moving lever 312 is inserted into the first slot segment 354 and the second slot segment 358.

[0050] In the structure provided in this embodiment, the movable through slot 355 has a bend, thus dividing into a third slot segment 356 and a fourth slot segment 357. The operator needs to manually control the first actuating lever 311 to pass through this bend before it can drive the moving lever 312 to continue moving, thereby opening the first docking notch 352. This effectively reduces the probability of the first notch opening and the safety rope 4 becoming loose due to accidental movement of the first actuating lever 311 caused by environmental factors, and effectively improves the safety of the fall arrest device 3 and even the climbing assistance system 1.

[0051] In one specific embodiment of this application, the fall arrestor 3 may further include a safety switch 36, which may include a first torsion spring 361, a third pin 362, and a second actuating lever 363. The third pin 362 may be connected to the housing 35 and the second actuating lever 363 parallel to the first direction X. The first torsion spring 361 is sleeved on the third pin 362 and abuts against the housing 35 and the second actuating lever 363. Under the abutment of the first torsion spring 361, the second actuating lever 363 can limit the first actuating lever 311 to one end of the third groove 356 away from the fourth groove 357.

[0052] The structure provided in this embodiment allows the first torsion spring 361 and the second actuating lever 363 to limit the first actuating lever 311. The operator needs to manually control the second actuating lever 363 to deform the first torsion spring 361 before the first actuating lever 311 can drive the moving lever 312 to continue moving, thus opening the first docking notch 352. Therefore, the safety switch 36 effectively reduces the probability of the first actuating lever 311 opening due to erroneous operation caused by environmental factors, leading to the safety rope 4 becoming loose, and effectively improves the safety of the fall arrest device 3 and even the climbing assistance system 1.

[0053] Optionally, the first actuating lever 311 can be specifically limited to both sides of the second actuating lever 363 parallel to the first direction X. When the first actuating lever 311 is located on the side of the second actuating lever 363 away from the second groove section 358, the first actuating lever 311 is limited by the second actuating lever 363, so that the first docking notch 352 can remain open, so that the operator does not need to control the first actuating lever 311 by hand, thereby facilitating the installation of the safety rope 4 and improving the availability of the fall arrestor 3 and even the climbing assistance system 1.

[0054] In one specific embodiment of this application, the fall arrestor 3 may further include a second torsion spring 38. One end of the second torsion spring 38 is connected to the rope-pressing member 34, and the other end is connected to the end of the second pin 33 through which the first pin 32 passes. The rope-pressing member 34 is rotatable about the second pin 33. When the rope-pressing member 34 rotates about the second pin 33 to lock the safety rope 4 into the receiving slot 351, the second torsion spring 38 deforms.

[0055] When the worker is working normally and no fall occurs, under the action of the second torsion spring 38, there is sufficient space between the rope-pressing component 34 and the receiving groove 351 for the safety rope 4 to move freely relative to the rope-pressing component 34. In the event of a fall, the rope-pressing component 34 is pulled by the safety belt 5, and the second torsion spring 38 deforms, allowing the rope-pressing component 34 to rotate around the second pin 33 until it presses against the rope and the bottom of the receiving groove 351, thereby fixing the fall arrest component to a certain position on the safety rope 4, thus stopping the worker's fall and achieving the fall arrest effect. After the worker is safe, the rope-pressing component 34 loses the pull of the safety belt 5 and can automatically return from the locked state of the safety rope 4 under the elastic action of the second torsion spring 38, allowing the safety rope 4 to slide normally in the receiving groove 351, which can improve the usability of the climbing assistance system 1.

[0056] In one specific embodiment of this application, the rope-pressing component 34 may further include a limiting rod 341. The rope-pressing component 34 is able to swing relative to the receiving through groove 351 between a third position and a fourth position, with the second pin 33 as the axis. When the rope-pressing component 34 is in the third and fourth positions, the limiting rod 341 can abut against the housing 35, thereby limiting the range of swing of the rope-pressing component 34 relative to the housing 35. This reduces the probability of accidents such as the rope-pressing component 34 swinging to an abnormal position, causing the fall arrest component to abnormally lock the safety rope 4 or fail to lock the safety rope 4, thus improving the stability of the climbing assistance system 1.

[0057] Optionally, the limit rod 341 can be set parallel to the second direction Y.

[0058] In one specific embodiment of this application, the crossbar 22 may include a fourth pin 223 and a fifth pin 226. The extension direction of the fourth pin 223 is parallel to the extension direction of the fifth pin 226, and the extension direction of the fourth pin 223 is perpendicular to the extension direction of the crossbar 22. The fourth pin 223 is located at the first end 221, and the fifth pin 226 is located at the second end 224.

[0059] The U-shaped frame 21 may have a third end 211 and a fourth end 213 on both sides of the opening. The third end 211 has a second mating notch 212, which mates with a fourth pin 223. The fourth end 213 has a third mating notch 214, which mates with a fifth pin 226. The second mating notch 212 faces upward, and the third mating notch 214 faces downward.

[0060] In the structure provided in this embodiment, when the first end 221 rotates about the second end 224, the fifth pin 226 actually rotates relative to the third docking notch 214. When the rotation reaches a certain extent, a notch is formed between the first end 221 and the third end 211 to allow the crossarm 61 to enter and exit. When the second end 224 rotates about the first end 221, the fourth pin 223 actually rotates relative to the second docking notch 212. When the rotation reaches a certain extent, a notch is formed between the second end 224 and the fourth end 213 to allow the crossarm 61 to enter and exit. This allows for flexible relative movement between the crossbar 22 and the U-shaped frame 21, achieving the effect of attaching the safety rope 4 to the crossarm 61.

[0061] Optionally, the U-shaped frame 21 may also include a reinforcing strip 215, which is provided on at least one side of the U-shaped frame 21 to improve the structural strength and service life of the U-shaped frame 21, so as to adapt to different working conditions and improve the durability of the climbing assistance system 1.
