Remote defect isolation device for vehicle doors and isolation method

摘要

The present invention relates to a remote defect isolation device for vehicle doors, comprising a remote isolation controller (1), an isolator body, a hook (3), a carrier (4), a cam (7) as well as a clamping device. The clamping device comprises an iron core (9) and an electromagnet (8) around the outside of the iron core (9). A spring is arranged between the iron core (9) and the electromagnet (8); a switch (5) is arranged on the isolator body; a plate spring (10) is fixedly arranged on the isolator body; a steel wire rope (6) is arranged on the cam. At the same time, the present invention discloses the isolation method of the isolation device. Comparing to the state-of-the-art, the present invention can directly close and isolate the defective door to quickly terminate their service, by means of the remote control device. There is no need to reach every defective door, to manually operate its closing and isolation. The structure is reasonable; the control principle is simple and reliable; time can be saved; working efficiency is improved and serious disruptions such as passenger clearance can be avoided.
