The invention discloses a cam type boot removing device, belonging to a current acceptor boot removing device. The cam type boot removing device mainly solves the technical problems that the conventional current acceptor is difficultly quickly isolated with a third rail and the like. The invention adopts the technical scheme that: the boot removing device (20) comprises a bracket (3), a lock catch (5), a cam (6), a rotary rod (8), a rotary arm (11) and a tension compression rod (14), wherein the lock catch (5) and the cam (6) are matched and arranged in the bracket (3); one end of the rotary rod (8) is rigidly connected with the cam (6) on the bracket (3), and the other end of the rotary rod (8) passes through the bracket (3) and is rigidly connected with the rotary arm (11) at the outer side; the free end of the rotary arm (11) is connected with the tension compression rod (14); a tension spring (10) is arranged between the rotary arm (11) and the bracket (3); a compression spring (18) is arranged between the inner end of the lock catch (5) and the bracket (3); a balance crow plate is arranged between the lock catch (5) and the cam (6); and the outer end of the lock catch (5) is in an inclined plane structure. When the current acceptor or a locomotive bus has ground fault and the like, the current acceptor can be quickly isolated with the third rail through the cam type boot removing device, so that normal operation of power transformation of a three-rail circuit is ensured, and the reliability of locomotive operation is improved. The cam type boot removing device can be widely applied to the current acceptor of a rail vehicle.
Description
technical field [0001] The invention relates to a boot removal device for a rail vehicle current collector. Background technique [0002] At present, the function of the upper or lower three-rail current receivers used at home and abroad is to introduce current from the third rail to the locomotive so that the locomotive can obtain power. It is difficult for the current collector to quickly isolate the current collector from the third rail. Contents of the invention [0003] The purpose of the present invention is to provide a method that can quickly isolate the current receiver from the third rail when the current receiver or the busbar of the locomotive has a fault such as grounding, so as to ensure the normal operation of the substation of the three-rail line and improve the reliability of locomotive operation. Sexy cam-type boot-off device. [0004] The technical solution adopted by the present invention to solve its technical problems is: the shoe-off device 20 incl...
