Multi-purpose safety belt fixed step stool frame

Abstract

The invention relates to a multi-purpose safety belt fixed step stool frame, a step frame comprises step legs which are in mirror symmetry and support each other and cross bars which are uniformly distributed between the step legs, and the innovation points are as follows: (1) a U-shaped fixed foot plate is respectively horizontally hinged between ground feet at the lower end of each step leg, and the opening of each U-shaped fixed foot plate is outward; and (2) step stool components are respectively hinged on the outer sides of the two step legs on the same side in the same direction, each step stool component comprises a universal hinge seat, a step stool pedal plate and a step stool vertical plate, the inner ends of the step stool pedal plates are hinged on the step legs through the universal hinge seats, the outer ends of the step stool pedal plates are hinged with the step stool vertical plates through hinge seats, and openings in the same direction with the U-shaped fixed foot plates are arranged at the lower ends of the step stool vertical plates. The whole multi-purpose safety belt fixed step stool frame is made of a high-strength nylon insulating material and light-weight super-hard aluminum, the step frame is designed to be lighter, convenient to carry, good in safety and in line with ergonomic requirement, and the multi-purpose safety belt fixed step stool frame can not only meet the related work of high-voltage testing, but also be used by part of electric power maintenance staff when 110kV and 35kV knife gates are maintained.

Description

technical field [0001] The invention belongs to the field of electric power, and relates to a tool for electric work, in particular to a multipurpose safety belt fixed step stool frame. Background technique [0002] When conducting 110kV and 35kV zinc oxide arrester tests, it is necessary to remove the primary lead wire of the arrester. Due to the narrowness of the site, sometimes bucket trucks cannot be used, and the test personnel can only climb on the structure of the arrester more than 2 meters high to disassemble the head. The position of the dismantling head is relatively high, and the staff generally need to stand on the toes to barely work. Those who are slightly shorter have to stand on the insulating platform of the lightning arrester to work. The strap is tied to the porcelain sleeve of the lightning arrester. [0003] According to 15.1.8 of the "Safety Regulations", the hook or rope of the safety belt should be hung on a strong and firm component, or on a steel...

AI Technical Summary

Problems solved by technology

[0004] However, there have been many death incidents in other places where the porcelain insulation breaks and falls due to the safety belt being tied to the porcelain insulation.

At present, there is no ideal safety belt fixing device in China. The existence of the above-mentioned safety hazards seriously threatens the personal safety of electric power workers and the production safety of enterprises.
