Fixed safety belt suspension device for maintenance of substation power equipment

Abstract

The invention provides a fixed safety belt suspension device for maintenance of substation power equipment. The fixed safety belt suspension device comprises a vertical pipe, a safety belt hanging ring and a fixing structure, the vertical pipe and the power equipment are fixed together through the fixing structure, the fixing structure and the vertical pipe are detachably fixed together, the fixing structure comprises a wire pole fixing structure and a cross rod fixing structure, and the two fixing structures share one vertical pipe and can be mutually replaced in use. The fixing structure andthe vertical pipe can be detached, thus when different power equipment is maintained, different fixing structures can be selected to be matched with the vertical pipe so as to achieve the purpose ofmaintenance, a suspension device is fixed to a wire pole or a cross rod during current maintenance, thus the fixing structure specifically comprises the wire pole fixing structure and the cross rod fixing structure, different maintenance situations can be met, the types and models of the fixing structures can be well reduced, and the problems that the cost is increased due to the excessive types and models, and storage is inconvenient are solved.

Description

technical field [0001] The invention relates to a safety protection device for power equipment maintenance, in particular to a fixed safety belt suspension device for substation power equipment maintenance. Background technique [0002] During the maintenance and construction of large-scale power transmission and transformation equipment, the operator must strictly follow the operating procedures for safety protection. When working at heights, the operator should fasten the safety belt, and at the same time connect the safety belt to the equipment structure reliably and firmly. It can effectively prevent the operator from stepping on the air and falling, and using the seat belt correctly is an important measure to prevent personal accidents. When overhauling electrical equipment such as coupling capacitors and arresters with voltage levels of 35KV and 110KV, there should be safe and reliable anti-fall measures. Due to the variety of structures and sizes of on-site equipment...

AI Technical Summary

Problems solved by technology

Due to the variety of structures and sizes of on-site equipment, it is impossible to reliably fix the safety belt suspension device. Maintenance personnel often hang the safety belt on the porcelain bottle, which may cause personal injury and equipment damage due to porcelain bottle breakage.

[0003] The bases of various equipment in the substation are made of circular equal-diameter cement poles and steel poles. There is no suitable safety belt suspension point on the pole body, and there is a disadvantage of "low hanging and high use" of safety belts when hanging on the horizontal structure. Many structural designs It is also not possible to add other types of seat belt hangers

When performing equipment maintenance, the maintenance personnel are very passive while standing on the equipment structure or insulation ladder, and the safety belt cannot effectively protect the safety

Due to the dense arrangement of various large-scale equipment, the use of lift trucks is not only costly, but also the lift trucks cannot be approached

In particular, cement rods are not easily bolted due to their smooth surfaces, and cannot be fixed by welding

[0004] In addition, existing suspension devices generally include standpipes, seat belt hanging rings on the standpipes and fixed structures fixed with electrical equipment. Due to different equipment, the fixed structures are also different, so that the suspension devices need to be equipped with Multiple models or sizes increase the cost of using the suspension device, that is, increase the maintenance cost of electrical equipment
