Description

Technical Field

[0001] The utility model relates to the technical field of safety belt suspension, in particular to a safety belt suspension device for substation maintenance. Background Technique

[0002] During substation maintenance, maintenance personnel need to wear safety belts to work at heights. However, for the places where the safety belts need to be suspended, generally, a safety belt suspension device is used to fix them on columns or telegraph poles.

[0003] According to a substation maintenance safety belt suspension device disclosed in Chinese Patent with the publication number of "CN208339946U", which includes a slide rail. Cross bars are perpendicularly welded to the upper and lower ends of the slide rail. A left clamp is fixed on the cross bar. The left clamp is connected to a right clamp through bolts. Anti-slip spikes are provided on the inner walls of the left clamp and the right clamp. A slider is slidably connected to the slide rail. A support plate is perpendicularly fixed on the slider. A hanging ring is fixed on the support plate. A spring is provided between the cross bar at the lower end of the slide rail and the slider. The spring is sleeved on the slide rail. By setting two clamps, the fixing property is increased, the anti-slip property of the clamps is increased by the anti-slip spikes, and the safety is improved. And when a person accidentally falls, the spring can buffer to reduce people's pain. When the above device is in use, since the inner diameter after the left and right clamps are combined is fixed, when it is necessary to fix it on a thinner column or telegraph pole, it is easy to have the problem that it cannot be effectively fixed, resulting in a sliding problem caused by insecure fixation. Therefore, a substation maintenance safety belt suspension device is proposed to solve the above-mentioned problems. Summary of the Utility Model
