Long-distance tripping protection device for dispatching winch

Abstract

The invention belongs to the technical field of automatic control, and particularly relates to a long-distance tripping protection device for a dispatching winch. The protection device comprises a first dispatching winch control module, a dispatching winch power source, a second dispatching winch control module, a dispatching winch power supply main feed, a first dispatching winch contactor, a second dispatching winch contactor, a first dispatching winch motor and a second dispatching winch motor; the output end of the first dispatching winch control module is respectively connected to input ends of the dispatching winch power supply main feed and the first dispatching winch contactor, the output end of the second dispatching winch control module is respectively connected to input ends ofthe dispatching winch power supply main feed and the second dispatching winch contactor, and the output end of the dispatching winch power source is connected to the input end of the dispatching winchpower supply main feed. By adopting the protection device, parking can be achieved in time when faults such as contactor blocking, adhesion, remanence and the like occur, so that the occurrence of mechanical and electrical accidents is prevented.

Description

technical field [0001] The invention belongs to the technical field of automatic control, in particular to a long-distance trip protection device for a dispatching winch. Background technique [0002] The power distribution cabinet of the dispatching winch is usually far away from the loading operation room. The equipment has a large capacity and a large selection of contactors. Faults such as contactor jamming, adhesion, and residual magnetism often occur. The operator cannot stop in time, causing the traction wire rope to bite. , burning out the motor and other accidents, affecting the coal loading of the train, and causing great economic losses. Therefore, it is urgent to propose a long-distance dispatching winch that can stop in time when there are faults such as contactor stuck, adhesion, and residual magnetism. Buckle protector. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides a...
