Problems solved by technology

At present, most of them are disassembled by manual operation. There are many defects in this original manual disassembly method: ①, because the spring tension is very large, it generally requires a person with greater strength to disassemble, and the disassembly process is very difficult for the operator. The practical experience required is high, and the operation is difficult; ②, manual

Abstract

Disclosed is an isolation-switch contact-finer dismounting device which includes a base and handles, and the two handles are hinged through a hinging shaft. A round shaft is arranged vertically on the base. The hinging shaft is provided with a moving positioning rod. The front end of the moving positioning rod is provided with a round ring. The round shaft is sleeved with the round ring. The rear part of the moving positioning rod is provided with a slide groove. The hinging shaft is located in the slide groove. The end parts of the handles are provided with contact-finger snap joints. A screw rod is arranged between the two handles. An adjustment handle is arranged on the screw rod. Through adoption of the technical scheme, the contact-finger snap joints are arranged at the end parts of the handles and the screw rod is arranged between the two handles and the adjustment rod is arranged on the screw rod. Thus, when a spring is dismounted, the adjustment handle can be slowly flicked so that the adjustment handle moves on the screw rod and thus the opening degree between the handles is adjusted slowly and it can be ensured that during a spring dismounting process, the spring does not burst open and thus the personal security of work personnel is ensured.

Description

technical field [0001] The invention relates to an electric auxiliary tool, in particular to a device for disassembling and assembling contact fingers of an isolating switch. Background technique [0002] Maintenance of isolating switches is a common occurrence in the power industry, and disassembly and assembly of the contact fingers are generally required for maintenance of isolating switches. At present, most of them are disassembled by hand, and there are many defects in this original manual disassembly method: ①, because the spring tension is very large, it generally requires a person with greater strength to disassemble, and the disassembly process is harmful to the operator The practical experience required is high, and the operation is difficult; ②, manual disassembly and assembly will cause great damage to the contact fingers and springs, and easily cause damage to related components, which not only increases the maintenance cost, but also needs to be disassembled a...
