Maintenance car of handcart type breaker equipment

Abstract

The invention relates to a maintenance car of handcart type breaker equipment. The maintenance car comprises a carframe, a braking mechanism, a bearing suspension mechanism, a guide rail lifting device and a clamping device, wherein the carframe comprises two supports, an upper beam and a lower beam; the upper and lower beams are fixed at the back parts of the two supports respectively; the back part of each of the two supports is provided with an upright guide rail with an opening; the openings of the upright guide rails are opposite; a driving gear shaft is arranged at the back part of the carframe; the braking mechanism is arranged on the carframe; two vertically-arranged racks of the bearing suspension mechanism are respectively connected with connecting plates; driving gears at the two sides of the driving gear shaft are meshed with the two racks; idler wheels at the side parts of the connecting plates are arranged in the two upright guide rails of the two supports; guide rail shafts are fixed on the two connecting plates; fixed guide rails are fixed on the guide rail shafts; movable guide rails are sheathed on the guide rail shafts and can move axially; and the guide rail lifting device and the clamping device are arranged on one of the supports. The maintenance car can be used for maintaining the handcart type breaker equipment safely and reliably in field, is convenient in the operation and can improve the maintenance working efficiency.

Description

technical field [0001] The invention relates to a handcart type circuit breaker equipment maintenance vehicle, which belongs to the technical field of electrical maintenance auxiliary tools. Background technique [0002] The middle-mounted high-voltage switchgear is widely used in power distribution and transformation in various industries and fields such as power plants, substations, industrial and mining enterprises, railway transportation, high-rise buildings, etc. It is responsible for the distribution of electric energy, and controls, protects and monitors circuits. Wait. The removable high-voltage switchgear is usually composed of a control room, a circuit breaker room, a busbar room and a cable room. A group of static contact seats as a static contact device are fixed in the chamber of the circuit breaker room. , The outlet static contact is connected with the external high-voltage power supply circuit. When the handcart circuit breaker is pushed into the circuit br...

Problems solved by technology

However, during the braking operation, the operator has to step on the pedal all the time, so that the transfer platform will not move, so it is inconvenient to operate

[0008] Furthermore, the current transfer vehicle is only used to support and transport the circuit breaker of the handcart. The transfer vehicle transports the circuit breaker of the handcart from the switch cabinet and places it on another workbench for maintenance, and then disconnects the circuit breaker of the handcart after maintenance Push the circuit breaker into the switch cabinet, because the transfer vehicle cannot be used to repair the circuit breaker of the opponent car, especially the staff cannot repair the circuit breaker of the opponent car on site, and the work efficiency of the repair cannot be improved
