Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling of transmission towers, and specifically relates to a flexible anti-falling track device for transmission line towers. Background Technique

[0002] According to the "Classification of High-place Operations" GB / T3608-2008 and the "Electric Safety Working Regulations - Electric Power Line Part", when the working height from the ground reaches 2m, it is regarded as high-place operation, and corresponding protection devices should be worn. When working on transmission towers, especially on high-level electric towers, the working height is often above 20m in the air. Traditional high-place operation protection devices usually have problems such as large weight, complex installation, and high cost, which limit their effects in practical applications. Nowadays, there are still phenomena that anti-falling protection device systems are not installed on transmission towers of various voltage levels, and the installed anti-falling protection device systems also have various forms and are not compatible with each other; sometimes, workers even need to carry supporting devices of various styles of high-place operation protection devices within a day's work, which greatly increases the operation burden of the staff. According to incomplete statistics, among the power personal injury accidents from 2012 to 2022, the accidents of falling from height accounted for 28% of the total number of accidents, and the death toll of the accidents of falling from height accounted for 35% of the total death toll.

[0003] An angle steel tower anti-falling device with the application number CN201920304251.7 includes a fixed groove body, a rotating seat, a limiting arm and a hinged main shaft.

[0015] Compared with the prior art, the beneficial effect of the present invention is that the flexible anti-falling track device of the transmission line tower is provided with:

[0016] 1. Self-locking structure. In this structure, when a worker accidentally falls from the upper end of the angle steel tower, the end plate connected to the safety ring will squeeze the telescopic spring, causing the second telescopic rod to slide along the inner side of the first telescopic rod, thereby causing the first bevel block connected to the outer side of the end plate to move downward accordingly. When moving downward, the first bevel block will engage with the second bevel plates on both sides, thereby squeezing the second bevel plates at both ends, causing the sliding blocks on their outer sides to slide along the inner side of the fall arrester and push the friction plates at both ends to move outward and contact the inner wall of the track device and generate friction. As the first bevel block continues to move downward, the friction force between the friction plates at both ends and the inner wall of the track device increases. When the friction force is greater than the gravity of the human body falling, the fall arrester will lock on the inner side of the track device and stop sliding downward, thereby preventing the worker from falling accidentally and protecting the worker.

[0017] 2. Angle adjustment structure. The safety ring of this structure is connected to the safety rope tied to the outside of the human body. A rotating sphere is installed at the bottom of the safety ring. The rotating sphere can rotate inside the positioning hole inside the connecting head. The connecting head is connected to the outside of the support seat through a concentric axis. The above structure allows the safety ring to be adjusted at multiple angles, avoiding the problem that the safety ring cannot be adjusted at an angle when workers are working at high altitudes, causing the safety rope to become tangled or the safety rope to be insufficient in construction length.
