Description

Technical Field

[0001] This utility model relates to the field of power transmission line maintenance technology, and in particular to a self-locking safety protection device for climbing power transmission towers. Background Technology

[0002] During the maintenance of power transmission lines on power towers, workers need to climb to the top of the tower and then cross the crossarm to enter the work site. Currently, the common safety measures used by workers during high-altitude tower climbing include track-type fall protection and alternating double safety belt protection.

[0003] Chinese patent document CN219271989U discloses a novel safety protection device for climbing power transmission towers, including a connecting belt and a clamping device. The clamping device includes an adjustable fastener and a collar assembly for fitting onto the tower foot spikes. The adjustable fastener is disposed on the collar assembly and is used to fix the collar assembly located on the tower foot spikes. The adjustment control part of the adjustable fastener is connected to one end of the connecting belt, and the other end of the connecting belt is used to connect to a work safety belt. This utility model allows workers to wear climbing gloves and hold the clamping device when climbing power transmission towers. They can then fit the collar assembly onto the tower foot spikes and adjust the adjustable fastener with their fingers to complete the fixation. The clamping device provides a hand fixation point while effectively reducing the force on the hands, saving workers' energy. In the event of an accidental fall, the connecting belt pulls the adjustable fastener, causing the collar assembly to tighten onto the tower foot spikes. This reduces equipment costs while improving the efficiency of climbing power transmission towers and ensuring the personal safety of workers.

[0004] The existing technology has the following problems:

[0005] When using the self-locking safety device for climbing power transmission towers, it cannot effectively restrict and fix the arc hook one and arc hook two, resulting in a low safety factor. Furthermore, the self-locking safety device for climbing power transmission towers cannot provide good anti-slip and protective functions when fixed in place. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 As shown, a self-locking safety protection device for climbing power transmission towers includes a connecting belt 1. A connecting ring 2 is movably sleeved on the outer wall of the upper part of the connecting belt 1. A fixed support assembly 3 is fixedly connected to the upper surface of the connecting ring 2. A safety protection assembly 4 is rotatably connected to the inner wall of the upper part of the fixed support assembly 3 and is located on the left side of the fixed support assembly 3. A second safety protection assembly 5 is rotatably connected to the inner wall of the upper part of the fixed support assembly 3 and is located on the right side of the fixed support assembly 3. The right side of the first safety protection assembly 4 overlaps with the left side of the second safety protection assembly 5.

[0028] First, the fixed support component 3 enables the safety protection component 1 4 and the safety protection component 2 5 to rotate and move. Then, the opened safety protection component 1 4 and the safety protection component 2 5 are moved to the outer wall of the tower foot nail 6 and then closed and fixed, thereby providing safety protection for the workers and ensuring their personal safety.

[0029] like Figure 2 , Figure 3 As shown, the fixed support assembly 3 includes a U-shaped plate 31, the lower surface of which is fixedly connected to the upper surface of the connecting ring 2. A fixed rod 32 is fixedly connected to the upper part of the inner wall of the U-shaped plate 31. The safety protection assembly 4 includes an arc-shaped hook 41, the outer wall of the lower part of the arc-shaped hook 41 is rotatably connected to the rear part of the outer wall of the fixed rod 32. An anti-slip pad 45 is fixedly connected to the inner wall of the arc-shaped hook 41. A handle 43 is fixedly connected to the lower surface of the upper part of the arc-shaped hook 41 and is located on the left side of the U-shaped plate 31. An automatic limit assembly 44 is fixedly connected to the inner cavity of the arc-shaped hook 41 and is located on the left side of the handle 43. The safety protection assembly 5 includes an arc-shaped hook 51, the outer wall of the lower part of the arc-shaped hook 51 is fixedly connected to the upper surface of the connecting ring 2. The front part of the outer wall of rod 32 is rotatably connected. The inner wall of arc hook 2 51 is fixedly connected with anti-slip pad 2 55. The lower surface of the upper part of arc hook 2 51 is fixedly connected with handle 2 53 and handle 2 53 is located on the left side of U-shaped plate 31. The inner cavity of arc hook 2 51 is fixedly connected with automatic limit component 2 54 and automatic limit component 2 54 is located on the left side of handle 2 53. The right side of the upper part of arc hook 1 41 is fixedly connected with arc limit plate 1 42. The left side of the upper part of arc hook 2 51 is fixedly connected with arc limit plate 2 52. The front of arc limit plate 1 42 overlaps with the back of arc limit plate 2 52. The opposite surfaces of the upper parts of handle 2 53 and handle 1 43 are fixedly connected with spring 1 33. The outer wall of spring 1 33 is movably sleeved with the inner wall of U-shaped plate 31.

[0030] By moving handle 1 (43) and handle 2 (53) in opposite directions, the arc hook 1 (41) and arc hook 2 (51) can rotate and move in opposite directions under the action of the fixing rod 32. Then, the arc hook 1 (41) and arc hook 2 (51) pass through the tower foot nail 6. Then, release handle 1 (43) and handle 2 (53) so that handle 1 (43) and handle 2 (53) can return to their original positions under the action of spring 1 (33). At this time, the arc limiting plate 1 (42) and arc limiting plate 2 (52) overlap, so that the connecting belt 1 and the connecting ring 2 can be fixed below the tower foot nail 6, thereby protecting the workers.

[0031] like Figure 4As shown, the automatic limiting component 44 includes a limiting block 441. The outer wall of the limiting block 441 is slidably connected to the inner wall of the upper part of the handle 43. An auxiliary handle 442 is fixedly connected to the left side of the limiting block 441 and the auxiliary handle 442 is located on the left side of the handle 43.

[0032] The limiting block 441 enables the auxiliary handle 442 to move up and down. During operation, the auxiliary handle 442 can be moved down to the left side of handle 43 first, and then handle 43 can be moved towards the U-shaped plate 31 to open the arc hook 41. The operation is simple and convenient.

[0033] like Figure 5 As shown, a pull rod 443 is fixedly connected to the upper surface of the limiting block 441. The outer wall of the pull rod 443 is movably sleeved with the inner cavity of the arc-shaped hook 41. The lower part of the outer wall of the pull rod 443 is slidably connected to a limiting sleeve 444. The outer wall of the limiting sleeve 444 is fixedly connected to the inner cavity of the arc-shaped hook 41. A fixed round rod 446 is fixedly connected to the upper surface of the pull rod 443, and the fixed round rod 446 is located above the limiting sleeve 444. The opposing surfaces of the fixed round rod 446 and the limiting sleeve 444 are fixed. A second spring 445 is connected, and the inner wall of the second spring 445 is movably sleeved with the outer wall of the pull rod 443. A connecting plate 447 is fixedly connected to the right side of the first fixed round rod 446. The outer wall of the connecting plate 447 is slidably connected to the inner cavity of the first arc hook 41. A second fixed round rod 448 is fixedly connected to the right part of the upper surface of the connecting plate 447. The lower part of the outer wall of the second fixed round rod 448 is inserted into the inner cavity of the first arc hook 41. The upper part of the outer wall of the second fixed round rod 448 is inserted into the inner cavity of the second arc limiting plate 52.

[0034] By moving the limiting block 441 and the auxiliary handle 442, the pull rod 443 can pull the fixed round rod 446 downward under the action of the limiting sleeve 444. At this time, under the action of the connecting plate 447, the fixed round rod 448 can move downward into the inner cavity of the arc hook 41. Then, when the arc hook 41 and the arc hook 51 are fixed on the outer wall of the tower foot nail 6, the fixed round rod 446 pushes the connecting plate 447 and the fixed round rod 448 upward through the action of the spring 445. This allows the arc limiting plate 52 to be inserted into the inner cavity of the arc limiting plate 52 when it moves in front of the arc limiting plate 42, thereby further restricting and fixing the arc hook 41 and the arc hook 51, thus improving the stability of the fixation and ensuring the safety of use.

[0035] like Figure 6As shown, the anti-slip mat 45 includes a connecting layer 451. The outer wall of the connecting layer 451 is fixedly connected to the inner wall of the arc-shaped hook 41. A granular rubber pad 452 is fixedly connected to the inner wall of the connecting layer 451. The inner wall of the granular rubber pad 452 overlaps with the outer wall of the tower foot nail 6. An elastic rubber pad 453 is fixedly connected to the inner cavity of the granular rubber pad 452.

[0036] The granular rubber pad 452 provides resistance to the arc-shaped hook 41 and arc-shaped hook 51 when they are fixed to the outer wall of the tower foot nail 6, thus preventing slippage and ensuring the stability of the fixation.

[0037] A sponge pad 454 is fixedly connected to the outer wall of the elastic rubber pad 453, and the outer wall of the sponge pad 454 is fixedly connected to the inner wall of the connecting layer 451.

[0038] Through the action of the sponge pad 454 and the elastic rubber pad 453, the granular rubber pad 452 can provide a certain buffer when it comes into contact with the tower foot spike 6, thereby reducing impact and playing a protective role.

[0039] The working principle of this utility model is as follows: First, by moving the limiting block 441 and the auxiliary handle 442, the pull rod 443 can pull the fixed round rod 446 downward under the action of the limiting sleeve 444. At this time, under the action of the connecting plate 447, the fixed round rod 448 can move downward into the inner cavity of the arc hook 41. Then, by moving the handle 43 and the handle 53 in opposite directions, the arc hook 41 and the arc hook 51 can rotate and move in opposite directions under the action of the fixed rod 32. Then, the arc hook 41 and the arc hook 51 pass through the tower foot nail 6. Then, the handle 43 and the handle 53 are released, so that the handle... Handle 43 and handle 53 can return to their original positions under the action of spring 33. At this time, arc-shaped limiting plate 42 and arc-shaped limiting plate 52 overlap. Then, the auxiliary handle 442 is released. Through the action of spring 445, the fixed round rod 446 pushes the connecting plate 447 and the fixed round rod 448 to move upward. This allows the arc-shaped limiting plate 52 to be inserted into the inner cavity of the arc-shaped limiting plate 52 when it moves to the front of the arc-shaped limiting plate 42. This further restricts and fixes the arc-shaped hook 41 and arc-shaped hook 51, thereby providing safety protection for the workers and ensuring their personal safety.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
