Problems solved by technology

[0004] The purpose of the present invention is to provide a special safety belt suspension device for switchgear inspection and maintenance, to solve the safety belt suspension that exists in the high-voltage switchgear maintenance safety belt suspension at the present stage in the above-mentioned background technology, and there is a safety hazard of falling from high altitude. The safety belts of the staff are tied to the switchgear, and the safety belts of the personnel are hung low and high, which violates the safety regulations of power transformation. When the safety belt is hung on the rectangular busbar, there is a risk of insufficient support for the porcelain bottle and the porcelain bottle breaks. If the porcelain bottle breaks suddenly, the Problems that will cause serious threats and injuries to the personal safety of workers

Abstract

The invention discloses a special safety belt suspension device for switchgear inspection and maintenance, which comprises a metal suspension body, the metal suspension body is mainly composed of fixed steel bars, a slideway is provided on the fixed steel bar, and the inner wall of the slideway is provided with Expansion screw holes running through the fixed steel bar, the two ends of the fixed steel bar are provided with connecting holes; the safety belt sliding part, the safety belt sliding part includes a connecting ring, a fall arrester and a sliding plate, and the connecting ring is fixed on the The surface of the sliding plate, and the anti-fall device is installed in the connecting ring, and the sliding part of the safety belt is slidably connected to the fixed steel bar; the reinforcement assembly, the reinforcement assembly is detachably connected to both ends of the metal suspension body, the There is an open slot in the reinforcing component, and a fracture is provided at the bottom of the open slot, and a hydraulic rod is installed in the open slot. The installation of the device in the present invention eliminates injuries caused by improper suspension of seat belts, equipment damage, etc. The risk of accidents and the safety of personnel and equipment are guaranteed.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a special safety belt suspension device for switch cabinet maintenance. Background technique [0002] At present, 35kV and 10kV switch cabinets are mainly used in the low-voltage end equipment of the main network and distribution network, and the number is relatively large. During the inspection and maintenance of the busbar warehouse of the high-voltage switchgear, the on-site personnel often worry about the problem of hanging safety belts, which deeply troubles the maintenance personnel. The reason is that the switchgear is not designed with a reliable safety belt suspension point at this stage, and there is no special safety belt suspension device. Most of the safety belts are hung on the switch cabinet body during work, which will cause the staff: one is to work on the busbar warehouse of the switch cabinet, the staff need to work at high altitude, the safety belt is...
