Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology, specifically to a mechanism for preventing falls when climbing power transmission line towers. Background Technology

[0002] Transmission line towers are tower-like structures used for power transmission, supporting and suspending conductors, lightning protection wires, and other accessories to ensure prescribed safe distances between conductors, between conductors and towers, between conductors and lightning protection wires, and between conductors and the ground or objects they cross. The most common method for climbing transmission line towers is rope climbing.

[0003] According to a Chinese patent publication (CN220558438U), a fall protection mechanism for climbing power transmission line towers includes locking rings. The bottom of each locking ring is fixedly connected to the output end of a telescopic steel cable. The bottom of the telescopic steel cable is fixedly connected to a steel cable storage device. The bottom of the steel cable storage device is fixedly connected to a connecting block, and a waist strap is fixedly connected inside the connecting block. This fall protection mechanism for climbing power transmission line towers prevents injury or death if one of the locking rings is damaged during climbing by fixing two locking rings at the top. The waist strap and the leg loop straps at the bottom provide good protection for the user. The cushioning pad inside the waist strap effectively reduces the impact on the user's lower back. When the foot pedal is needed, the foot hook is released, and the foot pedal moves to the foot under the action of the telescopic pole for leverage, making it convenient for the user.

[0004] The locking rings in this device can prevent injuries and fatalities from falls during climbing. However, existing devices have the following problems: frequent locking ring engagement is required during climbing, and if the locking rings are damaged without warning measures, it can easily lead to a fall. Therefore, a fall prevention mechanism for climbing power transmission line towers is proposed. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides a technical solution: a fall prevention mechanism for climbing power transmission line towers, including a waist restraint belt 1;

[0032] The first buckle is fixedly connected to both ends of the waist restraint belt 1;

[0034] And a chest restraint strap 3 fixedly connected to the inner side of the two second buckles, a third buckle fixedly connected to the end face of the two chest restraint straps 3, and a fall prevention component 40 fixedly connected to the top surface of the waist restraint strap 1.

[0035] The inner side of the waist restraint belt 1 is fixedly connected to a support component 41.

[0036] The fall arrestor assembly 40 includes a telescopic steel cable 401 fixedly connected to the top surface of the waist restraint belt 1. A locking ring 402 is fixedly connected to the top surface of the telescopic steel cable 401. The locking ring 402 has a cavity inside, and a trapezoidal block 406 is arranged inside the cavity. A slider 408, a push block 4010, a connecting plate 4011, and an electrode plate 4012 are respectively arranged on the front and rear sides of the trapezoidal block 406. The bottom surface of the slider 408 is fixedly connected to the top surface of the push block 4010. The rear end face of the connecting plate 4011 is fixedly connected to the front face of the slider 408. The front face of the connecting plate 4011 is fixedly connected to the rear side of the electrode plate 4012. The side of the trapezoidal block 406 is slidably connected to the side of the push block 4010. A sliding rod 407 is arranged on the rear side of the slider 408. The front end face of the sliding rod 407 slides through the sliding rod. The rear side of block 408 extends to the front side of slider 408. A second spring 409 is sleeved on the surface of slider 407. The front and rear ends of the second spring 409 are fixedly connected to the rear side of slider 408 and the inner wall of cavity, respectively. Through the anti-fall assembly 40, the two sliders 408 drive the two electrode plates 4012 to contact, causing the buzzer 4013 to sound, thereby reminding the user that the locking ring 402 and the pull rod 403 are not fixed. When the pull rod 403 drives the trapezoidal block 406 to move upward, the push block 4010 is squeezed, causing the two electrode plates 4012 to disengage, so the buzzer 4013 does not sound, which makes it easy for the user to remind them during use, reducing the risk of falling when climbing power transmission line towers and improving the anti-fall effect for users.

[0037] There are two telescopic steel cables 401, and they are arranged symmetrically.

[0038] A pull rod 403, a pull plate 405, and a first spring 404 are provided below the locking ring 402. The upper and lower end faces of the first spring 404 are fixedly connected to the bottom surface of the locking ring 402 and the top surface of the pull plate 405, respectively.

[0039] The inner side of the locking ring 402 is provided with a sliding groove. The top surface of the pull rod 403 slides through the bottom surface of the locking ring 402, the sliding groove and the inner wall of the cavity to extend into the cavity. The top surface of the pull rod 403 is fixedly connected to the bottom surface of the trapezoidal block 406.

[0040] The electrode plates 4012 are positive and negative electrodes respectively. A buzzer 4013 is fixedly connected to the bottom surface inside the cavity. The receiving end of the buzzer 4013 is connected to the output end of the electrode plate 4012 respectively.

[0041] A sound transmission hole is provided through the inner side of the locking ring 402.

[0042] Example 2: Based on Example 1, a preferred embodiment of the fall prevention mechanism for climbing power transmission line towers provided by this utility model is as follows: Figure 1 , Figure 2 , Figure 5 and Figure 6As shown: The support assembly 41 includes a fixing plate 411 fixedly connected to the inner side of the waist restraint belt 1. A waist support plate 412 is provided on the front side of the fixing plate 411. A slot is opened through the rear side of the fixing plate 411. A third spring 415 and an airbag 416 are fixedly connected inside the slot. The front end face of the third spring 415 and the front side face of the airbag 416 are both fixedly connected to the rear side face of the waist support plate 412. A connecting pipe 417 is fixedly connected to the bottom end face of the air tube of the airbag 416. The left end face of the connecting pipe 417 is fixedly through the airbag. The inner wall of the slot extends to the left side of the fixed plate 411. An air pump 418 is fixedly connected to the left end of the connecting pipe 417. An air release valve button is provided inside the connecting pipe 417. Through the support component 41, the waist support plate 412 provides support for the user's waist, enhancing the user's comfort. At the same time, the angle of the waist support plate 412 can be adjusted by the airbag 416, thereby adjusting the angle of the waist support plate 412 according to the needs of use, improving the user's comfort when climbing power transmission line towers.

[0043] The outer surface of the third spring 415 is covered with hand guard foam 414, and the front and rear ends of the hand guard foam 414 are fixedly connected to the rear side of the waist support plate 412 and the inner side of the slot, respectively.

[0044] There are two lumbar support plates 412, and a soft pad 413 is fixedly connected to the front side of the lumbar support plate 412.

[0045] In use, the first buckle secures the waist restraint belt 1 to the user's waist, the second buckle secures the shoulder restraint belt 2, and the third buckle secures the chest restraint belt 3. Before climbing the transmission line tower, the user's waist comes into contact with the soft pad 413, and the waist support plate 412 and the soft pad 413 support the user's waist. When the angle of the waist support plate 412 needs to be adjusted, the air pump 418 is pressed, causing the airbag 416 to inflate, thereby changing the angle of the waist support plate 412. When climbing the transmission line tower, the pull plate 405 is pulled down, causing the pull rod 403 to move the trapezoidal block 406 downward. At this time, the first... When spring 404 is stretched, trapezoidal block 406 moves downward and no longer presses against push block 4010. The second spring 409 pushes slider 408 to move on slide rod 407, causing slide rod 407 to drive connecting plate 4011 closer together. As a result, the two electrode plates 4012 approach and contact each other, and then buzzer 4013 sounds an alarm, hooking lock ring 402 and releasing pull plate 405. The first spring 404 pushes pull rod 403 upward, causing trapezoidal block 406 to slide upward and push the two push blocks 4010. As a result, the two electrode plates 4012 separate, and buzzer 4013 stops sounding, thus reminding the user whether lock ring 402 is damaged.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
