Description

Technical Field

[0001] This utility model relates to the field of auxiliary climbing technology, and in particular to an auxiliary climbing tool for power transmission line steel pipe towers. Background Technology

[0002] Steel pipe towers are lattice-type towers whose main components are made of steel pipes, while other components are made of steel pipes or structural steel. In the existing transmission line erection technology, steel pipe towers have become the preferred equipment for erecting lines within urban areas due to their advantages such as small footprint and high strength. In order to facilitate maintenance personnel to climb the poles regularly for maintenance, steel structure staircases are usually pre-installed on steel pipe towers to assist in climbing, making it easier for maintenance personnel to climb the steel pipe tower using auxiliary climbing tools.

[0003] Existing auxiliary climbing tools for power transmission line steel pipe towers often involve manually locking safety locks and other auxiliary climbing tools onto the staircase during the climb. However, this frequent operation can easily lead to accidents or disengagement of the locks, causing danger. Furthermore, the climbing process relies entirely on arm and leg strength, and individual physical conditions vary, leading to fatigue when climbing to higher levels, increasing the workload of personnel and affecting the overall efficiency of power transmission line maintenance. Therefore, this paper proposes to design an auxiliary climbing tool for power transmission line steel pipe towers to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an auxiliary climbing tool for power transmission line steel pipe towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Design an auxiliary climbing tool for steel pipe towers of power transmission lines, including a steel pipe tower body, a tower base installed at the bottom of the steel pipe tower body, a tower top provided at the top of the tower base, a winch installed on one side of the outer surface of the tower top, multiple triangular load-bearing frames symmetrically fixedly connected to the outer surface of the steel pipe tower body, and climbing frames fixedly connected to one side of each of the multiple triangular load-bearing frames, two first rubber wheels rollingly arranged on the outer surface of the steel pipe tower body, a central shaft rotatably installed between the two first rubber wheels, a first auxiliary plate fixedly connected to the outer surface of the central shaft, a support block fixedly connected to the upper end of the first auxiliary plate, a support ring fixedly connected to the upper end of the support block, a steel wire rope wound on the inner side of the winch, and two second rubber wheels rollingly arranged on the outer surface of the steel pipe tower body.

[0007] Preferably, the two second rubber wheels are connected to a common shaft at their middle parts, a second auxiliary plate is fixedly connected to the outer surface of the rotating wheel, a short plate is rotatably connected to the upper end of the second auxiliary plate, the short plate is rotatably connected to the first auxiliary plate, and a hook is inserted into the inner side of the support ring, the hook being fixedly connected to the wire rope.

[0008] Preferably, a fixed arm is fixedly connected to the upper end of the first auxiliary plate, an adjusting arm is hinged to the upper end of the fixed arm, and a suction cup is fixedly connected to one end of the adjusting arm.

[0009] Preferably, a traction rod is movably disposed between the first auxiliary plate and the second auxiliary plate, and a first spring is fitted onto one side of the traction rod on the second auxiliary plate.

[0010] Preferably, two swing arms are rotatably connected to one side of the second auxiliary plate, and a second spring is connected to the corresponding side of the two swing arms. A reinforcing rod is fixedly connected to the bottom end of one side of the two swing arms, and a limit block is fixedly connected to the bottom end of each of the two reinforcing rods. A buckle is slidably installed between the two limit blocks.

[0011] The auxiliary climbing tool for steel pipe towers of power transmission lines proposed in this utility model has the following advantages:

[0012] By connecting the safety harness buckle to the hook, the winch retracts, causing the steel wire rope to wind up. The winding of the steel wire rope causes the hook to move, pulling the support ring. This movement causes the support block to move, pulling the first auxiliary plate upwards. This, in turn, causes the two first rubber wheels to roll on the outer surface of the steel pipe tower. Simultaneously, as the first auxiliary plate rises, the traction rod is lifted, compressing the first spring and causing the second auxiliary plate to move upwards. This causes the two rotating shafts to move the two second rubber wheels on the outer surface of the steel pipe tower. The movement of the second auxiliary plate causes the two swing arms to move, which in turn causes the reinforcing rod and the limiting block to move, further securing the hook and lifting the user upwards. During this process, the user will sway back and forth slightly. At this time, the hook slides within the limiting block, causing the two swing arms to unfold and stretch against the second spring. The user only needs to hold onto the climbing frame to ascend. When using the auxiliary climbing tool for power transmission line steel pipe towers, it can lock onto the worker once and no further operation is required, avoiding the danger of confusion caused by frequent lock replacement. In addition, it can automatically assist in climbing with the help of the tool, reduce the pressure of climbing and improve climbing efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4A climbing aid for a steel pipe tower of a power transmission line includes a steel pipe tower body 1, a tower base 7 installed at the bottom of the tower body 1, a tower top 4 at the top of the tower base 7, a winch 5 installed on one side of the outer surface of the tower top 4, multiple triangular load-bearing frames 2 symmetrically fixedly connected to the outer surface of the steel pipe tower body 1, and climbing frames 3 fixedly connected to one side of each of the multiple triangular load-bearing frames 2, two first rubber wheels 8 rollingly arranged on the outer surface of the steel pipe tower body 1, a central shaft rotatably installed between the two first rubber wheels 8, a first auxiliary plate 14 fixedly connected to the outer surface of the central shaft, a support block 11 fixedly connected to the upper end of the first auxiliary plate 14, a support ring 19 fixedly connected to the upper end of the support block 11, and the winch 5. A steel wire rope 6 is wound around the inner side of the steel pipe tower body 1. Two second rubber wheels 9 are rolled on the outer surface of the steel pipe tower body 1. The two second rubber wheels 9 are connected to a rotating shaft in the middle. A second auxiliary plate 16 is fixedly connected to the rotating outer surface. A short plate 18 is rotatably connected to the upper end of the second auxiliary plate 16. The short plate 18 is rotatably connected to the first auxiliary plate 14. A hook 25 is inserted through the inner side of the support ring 19. The hook 25 is fixedly connected to the steel wire rope 6. A traction rod 15 is movably inserted between the first auxiliary plate 14 and the second auxiliary plate 16. A first spring 17 is fitted on one side of the traction rod 15 on the second auxiliary plate 16. Two swing rods 20 are rotatably connected to one side of the second auxiliary plate 16. A second spring 21 is connected to the corresponding side of each swing arm 20. A reinforcing rod 23 is fixedly connected to the bottom end of one side of each swing arm 20. A limit block 22 is fixedly connected to the bottom end of each of the two reinforcing rods 23. A buckle 24 is slidably installed between the two limit blocks 22. By engaging the buckle of the safety strap tied to the body with the buckle 24, the winch 5 is opened by the external controller. After the winch 5 is driven, it retracts and drives the wire rope 6 to wind up. The wire rope 6 retracts during winding, which drives the hook 25 to move. Under the pull of the hook 25, the support ring 19 moves accordingly, which drives the support block 11 to move and pulls the first auxiliary plate 14 to rise. Then, it drives the two first rubber wheels 8 to move on the steel pipe tower body. The outer surface of the steel pipe tower 1 rolls, and during the rise of the first auxiliary plate 14, the traction rod 15 is lifted, thereby compressing the first spring 17 and driving the second auxiliary plate 16 to move upward. This causes the two rotating shafts to drive the two second rubber wheels 9 to roll on the outer surface of the steel pipe tower 1. When the second auxiliary plate 16 moves, it drives the two swing rods 20 to move, which in turn drives the reinforcing rod 23 and the limiting block 22 to move. This further engages the buckle 24 and drives the user to rise. During the process, the person will swing back and forth slightly. At this time, the buckle 24 slides in the limiting block 22, causing the two swing rods 20 to unfold and stretch with the second spring 21. When the user is rising, he only needs to hold the climbing frame 3 with his hands to climb.

[0020] A fixed arm 13 is fixedly connected to the upper end of the first auxiliary plate 14. An adjusting arm 12 is hinged to the upper end of the fixed arm 13. A suction cup 10 is fixedly connected to one end of the adjusting arm 12. When the predetermined height is reached, the personnel can adjust the angle of the suction cup 10 through the adjusting arm 12, thereby fixing the detection instrument for use.

[0021] Working principle:

[0022] In use, this invention involves aligning the safety harness buckle with buckle 24, then controlling the winch 5 from an external controller to open. The winch 5 then retracts, winding the wire rope 6. As the wire rope 6 winds, it retracts, causing the hook 25 to move. The hook 25 pulls the support ring 19, causing the support block 11 to move and pull the first auxiliary plate 14 upwards. This, in turn, causes the two first rubber wheels 8 to roll on the outer surface of the steel pipe tower 1. Simultaneously, as the first auxiliary plate 14 rises, the traction rod 15 is lifted, compressing the first spring 17 and causing the second auxiliary plate 16 to move upwards. After driving the two rotating shafts, the two second rubber wheels 9 roll on the outer surface of the steel pipe tower body 1. When the second auxiliary plate 16 moves, it drives the two swing rods 20 to move, which causes the reinforcing rod 23 and the limiting block 22 to follow suit. This further engages the buckle 24 and lifts the user up. During the process, the person will swing back and forth slightly. At this time, the buckle 24 slides in the limiting block 22, which drives the two swing rods 20 to unfold and stretch with the second spring 21. When the user is rising, he only needs to hold the climbing frame 3 to climb. When the predetermined height is reached, the person can adjust the angle of the suction cup 10 through the adjusting arm 12 to fix the detection instrument for use.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
