[0002] With the development of power technology, the distribution network has become more and more complex. In order to save space and cost, it is very common for multiple lines to share one pole tower. Although this "multiple lines sharing one tower" layout has obvious advantages in improving land utilization and reducing the number of pole towers, it also brings challenges to maintenance operations. In particular, when workers climb poles to perform line maintenance or repairs, they need to strictly abide by safety regulations and use safety ropes and safety belts alternately to ensure that at least one of the safety ropes and safety belts is fixed to the pole tower at any time to prevent falling accidents during high-altitude operations.

[0031] With the development of power technology, the distribution network has become more and more complex. In order to save space and cost, it is very common for multiple lines to share one pole tower. Although this "multiple lines sharing one tower" layout has obvious advantages in improving land utilization and reducing the number of pole towers, it also brings challenges to maintenance operations. In particular, when workers climb poles to perform line maintenance or repairs, they need to strictly abide by safety regulations and use safety ropes and safety belts alternately to ensure that at least one of the safety ropes and safety belts is fixed to the pole tower at any time to prevent falling accidents during high-altitude operations.

[0032] This operation process is cumbersome and time-consuming, greatly reducing work efficiency.

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

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

Figure 7 It is a schematic diagram of the assembly structure of an embodiment of the anti-falling device provided in the present application. Figure 8 yes Figure 7 A cross-sectional structural schematic diagram of an embodiment of a fall prevention device is shown. Fig. 9 It is a schematic diagram of the structure of the anti-fall device and the safety rope provided in the present application before being assembled. Fig.10 The embodiment of the present application provides a climbing assistance system 1, including a hanging rope device 2 and an anti-falling device 3.

[0035] The rope hanging device 2 may include a U-shaped frame 21 and a crossbar 22, wherein the crossbar 22 includes a first end 221 and a second end 224, and the first end 221 and the second end 224 are detachably connected to both sides of the opening of the U-shaped frame 21. The first end 221 can rotate upward with the second end 224 as an axis, and the second end 224 can rotate downward with the first end 221 as an axis, and 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 hang the safety rope 4 on the cross arm 61 of the pole tower 6. During the hanging process, the operator on the ground can first press the lower surface of the cross arm 61 with the cross bar 22. At this time, the operator can release the control of the safety rope 4, so that the cross bar 22 rotates downward with the first end 221 as the axis under the action of the cross bar 22, so that the cross arm 61 can smoothly pass through the opening of the U-shaped frame 21 and enter the opening of the U-shaped frame 21. After the cross arm 61 enters, the operator can pull the safety rope 4, so that the cross bar 22 rotates upward with the first end 221 as the axis under the action of the safety rope 4, so that the second end 224 docks with the opening of the U-shaped frame 21 again, and the cross arm 61 is limited between the U-shaped frame 21 and the cross bar 22. Then the operator can directly pull the U-shaped frame 21 downward, and the first end 221 of the cross bar 22 rotates upward with the second end 224 as the axis under the action of the cross arm 61, so that a gap appears between the first end 221 and the U-shaped frame 21, and the cross arm 61 can be withdrawn through the gap, and the safety rope 4 can be hung on the cross arm 61 as the U-shaped frame 21 moves downward, thereby achieving the purpose of the operator setting the safety rope 4 at a high place.

[0037] The anti-fall device 3 includes a movable control rod 31, a first pin shaft 32, a second pin shaft 33, a rope pressing member 34 and a housing 35. The housing 35 is provided with a receiving slot 351 along a first direction X, and the receiving slot 351 is used to pass the safety rope 4. The first pin shaft 32 is connected to the housing 35 and one end of the second pin shaft 33 in parallel with the first direction X, and the other end of the second pin shaft 33 is penetrated in the rope pressing member 34 along a second direction Y, and the second direction Y is perpendicular to the first direction X. The side wall of the receiving slot 351 away from the first pin shaft 32 is provided with a first docking notch 352, and the movable control rod 31 is arranged corresponding to the first docking notch 352. The movable control rod 31 can be used to open or close the first docking notch 352, and the second pin shaft 33 can be rotated into the first docking notch 352. The rope pressing member 34 can be used to connect the safety belt 5.

[0038] When the operator is working normally and does not fall, there is enough space between the rope pressing member 34 and the receiving slot 351 for the safety rope 4 to move freely relative to the rope pressing member 34. When a fall occurs, the rope pressing member 34 is pulled by the safety belt 5, so that the rope pressing member 34 can rotate with the second pin 33 as the axis until the rope pressing member 34 presses against the rope and the bottom of the receiving slot 351, thereby fixing the anti-falling component at a certain position of the safety rope 4, thereby stopping the operator's tendency to fall and achieving an anti-falling effect.

[0039] Among them, the movable control rod 31 is movably connected to the shell 35, and the movable control rod 31 can move between a first position A and a second position B relative to the shell 35. When the movable control rod 31 is at the second position B, the movable control rod 31 limits the second pin shaft 33 in the first docking notch 352, and the rope pressing member 34 can limit the safety rope 4 in the accommodating groove 351.

[0040] In the embodiment of the present application, the crossbar 22 with flexible rotation at both ends can cooperate with the U-shaped frame 21, and can smoothly hang the safety rope 4 to a high place such as the pole tower 6. The operator can fix the safety rope 4 without climbing the pole tower 6, which greatly improves the safety of the pole climbing operation. At the same time, the anti-fall device 3 can fix the safety belt 5 connected to the operator with the safety rope 4, solving the problem of frequent switching between the safety belt 5 and the safety rope 4. The anti-fall device 3 cooperates with the hanging rope device 2 to effectively ensure the safety of the on-site operators, reduce the operation content and steps, and greatly improve the safety and efficiency of the pole climbing operation.

[0041] Specifically, the first end 221 may be provided with a first connection buckle 227, and the cross bar 22 is connected to one end of the safety rope 4 through the first connection buckle 227. The end of the rope pressing member 34 away from the accommodating through slot 351 may be provided with a second connection buckle 342, and the rope pressing member 34 is connected to the safety belt 5 through the second connection buckle 342.

[0042] like Fig. 9 , Fig.10 As shown, the end of the rope pressing member 34 facing the receiving slot 351 may be provided with a fixed inclined slot 343. Since the safety rope 4 is arranged vertically under the action of gravity, the anti-falling assembly connected to the safety rope 4 is also arranged vertically. Due to the existence of the fixed inclined slot 343, the distance between the end of the rope pressing member 34 facing the receiving slot 351 and the bottom of the receiving slot 351 decreases as the height decreases.

[0043] When the operator is working normally and does not fall, the rope pressing member 34 can be rotated with the second pin shaft 33 as the axis until the fixed inclined groove 343 is parallel to the first direction X, so that there is enough space between the rope pressing member 34 and the receiving groove 351 for the safety rope 4 to move freely relative to the rope pressing member 34. When a fall occurs, the rope pressing member 34 is pulled by the safety belt 5, so that the rope pressing member 34 can be rotated with the second pin shaft 33 as the axis until the rope pressing member 34 is pressed against the rope and the bottom of the receiving groove 351, thereby fixing the anti-falling component at a certain position of the safety rope 4, thereby stopping the operator's tendency to fall and achieving an anti-falling effect.

[0044] In a specific embodiment of the present application, the housing 35 may be provided with a movable slot 353 parallel to the first direction X, and the movable slot 353 includes a first slot section 354 and a second slot section 358, and the first slot section 354 and the second slot section 358 are respectively arranged on both sides of the opening of the first docking notch 352. When the movable control rod 31 is located at the second position B, the movable control rod 31 is simultaneously arranged in the first slot section 354 and the second slot section 358, so that the opening of the first docking notch 352 can be closed.

[0045] Through the structure provided in this embodiment, the plug-in relationship between the movable control rod 31 and the first slot section 354 and the second slot section 358 can be used to control the opening and closing of the first docking notch 352, thereby effectively controlling the limiting of the second pin shaft 33.

[0046] In a specific embodiment of the present application, the anti-fall device 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 is deformed. 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 shaft 33 accidentally falls out of the first docking notch 352, causing the safety rope 4 to loosen from the anti-fall assembly and cause a safety hazard, and can improve the safety of the anti-fall device 3.

[0047] In a specific embodiment of the present application, the movable control rod 31 may include a first toggle rod 311 and a moving rod 312. The side wall of the first slot section 354 is provided with an active through slot 355, the first toggle rod 311 is arranged at one end of the moving rod 312, and the moving rod 312 is arranged in the first slot section 354. The first toggle rod 311 can be exposed through the active through slot 355, and the first toggle rod 311 can move in the active through slot 355 parallel to the first direction X.

[0048] Through the structure provided in this embodiment, the operator can use the exposed first toggle rod 311 to drive the moving rod 312 to move, thereby achieving the effect of opening or closing the first docking gap 352, which can reduce the complexity of high-altitude operations. The cooperation between the first toggle rod 311 and the moving rod 312 can effectively improve the usability of the anti-fall device 3 and even the climbing assistance system 1.

[0049] In a specific embodiment of the present application, Figure 7 As shown, the movable through slot 355 may specifically include a third slot section 356 and a fourth slot section 357. One end of the third slot section 356 away from the second slot section 358 is connected to the fourth slot section 357. The first toggle rod 311 can rotate with the moving rod 312 as an axis to switch from the third slot section 356 to the fourth slot section 357. When the first toggle rod 311 is located in the third slot section 356, part of the moving rod 312 is inserted in the first slot section 354 and the second slot section 358.

[0050] In the structure provided in this embodiment, the movable through slot 355 is formed with a turn, thereby being divided into a third slot section 356 and a fourth slot section 357. The operator needs to manually control the first toggle rod 311 to pass through the turn before driving the moving rod 312 to continue to move, so as to open the first docking notch 352. This can effectively reduce the probability that the first notch is opened and the safety rope 4 is loosened due to the misoperation of the first toggle rod 311 due to environmental factors, and can effectively improve the safety of the anti-fall device 3 and even the climbing auxiliary system 1.

[0051] In a specific embodiment of the present application, the anti-fall device 3 may further include a safety switch 36, and the safety switch 36 may include a first torsion spring 361, a third pin 362, and a second toggle rod 363. The third pin 362 may be connected to the housing 35 and the second toggle rod 363 in parallel with the first direction X. The first torsion spring 361 is sleeved on the third pin 362, and the first torsion spring 361 abuts between the housing 35 and the second toggle rod 363. Under the abutment of the first torsion spring 361, the second toggle rod 363 can limit the first toggle rod 311 to an end of the third slot section 356 away from the fourth slot section 357.

[0052] Through the structure provided in this embodiment, the first torsion spring 361 and the second toggle rod 363 can be used to limit the first toggle rod 311. The operator needs to manually control the second toggle rod 363 to deform the first torsion spring 361 before the first toggle rod 311 can be used to drive the moving rod 312 to continue to move, so as to open the first docking notch 352. Therefore, the safety switch 36 can effectively reduce the probability that the first notch is opened and the safety rope 4 is loosened due to the misoperation of the first toggle rod 311 due to environmental factors, and can effectively improve the safety of the anti-fall device 3 and even the climbing auxiliary system 1.

[0053] Optionally, the first toggle rod 311 can be specifically limited to two sides of the second toggle rod 363 parallel to the first direction X. When the first toggle rod 311 is located on the side of the second toggle rod 363 away from the second slot section 358, the first toggle rod 311 is limited by the second toggle rod 363, so that the first docking notch 352 can be continuously opened, so that the operator does not need to control the first toggle rod 311 by hand, which is conducive to the operation of installing the safety rope 4, and can improve the usability of the anti-fall device 3 and even the climbing auxiliary system 1.

[0054] In a specific embodiment of the present application, the anti-fall device 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 second pin shaft 33 through which one end of the first pin shaft 32 is penetrated, and the rope pressing member 34 can rotate around the second pin shaft 33. When the rope pressing member 34 rotates around the second pin shaft 33 to lock the safety rope 4 in the receiving through groove 351, the second torsion spring 38 is deformed.

[0055] When the operator is working normally and does not fall, under the action of the second torsion spring 38, there is enough space between the rope pressing member 34 and the receiving slot 351 for the safety rope 4 to move freely relative to the rope pressing member 34. In the event of a fall, the rope pressing member 34 is pulled by the safety belt 5, and the second torsion spring 38 is deformed, so that the rope pressing member 34 can rotate with the second pin 33 as the axis until the rope pressing member 34 presses against the rope and the bottom of the receiving slot 351, thereby fixing the anti-falling component at a certain position of the safety rope 4, thereby stopping the operator's tendency to fall and achieving an anti-falling effect. After the operator recovers safety, the rope pressing member 34 loses the pull of the safety belt 5 and can automatically recover from the state of locking the safety rope 4 under the elastic action of the second torsion spring 38, so that the safety rope 4 can slide normally in the receiving slot 351, which can improve the usability of the climbing assistance system 1.

[0056] In a specific embodiment of the present application, the rope pressing member 34 may further include a limiting rod 341, and the rope pressing member 34 may swing between the third position and the fourth position relative to the accommodating through slot 351 with the second pin shaft 33 as the axis. When the rope pressing member 34 is located at the third position and the fourth position, the limiting rod 341 may abut against the housing 35, thereby limiting the swing range of the rope pressing member 34 relative to the housing 35, thereby reducing the probability of accidents such as the rope pressing member 34 swinging to an abnormal position, causing the anti-falling component to abnormally lock the safety rope 4, or failing to lock the safety rope 4, thereby improving the stability of the climbing assistance system 1.

[0057] Optionally, the limiting rod 341 may be arranged parallel to the second direction Y.

[0058] In a specific embodiment of the present application, the crossbar 22 may include a fourth pin 223 and a fifth pin 226, wherein 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.
