Description
Technical field
The present invention relates to a kind of pantagraph current collector, particularly relate to the pantagraph current collector of the usefulness that a kind of the 3rd rail that is suitable for urban rail transit vehicles flowed.
Background technology
Pantagraph current collector is a kind of current collection device that is installed on the urban rail transit vehicles bogie truck, and the moving contact through piston shoes on the pantagraph current collector and surface power supply rail is directed to the ground electric energy on the train.Pantagraph current collector under the effect of spring force, is pressed to power rail (the 3rd rail) with pantagraph current collector fork and pantagraph current collector piston shoes when normal operation, pantagraph current collector piston shoes and power rail are kept in touch.When vehicle runs into fault and will check or overhaul, need pantagraph current collector be broken off with power rail and contact, will pantagraph current collector piston shoes and power rail be forced disengagement, and be locked in disengaged position voluntarily.
In existing pantagraph current collector, the comparison representative type has pneumatic type to take off boots and boots are taken off in manual insulated handle operation.Pneumatic type is taken off boots and is adopted cylinder to drive the pantagraph current collector fork to take off boots, because the application of cylinder, has increased the size of pantagraph current collector structure; In railcar; The installation dimension space of bogie truck institute permission pantagraph current collector is very compact, and pneumatic type is taken off the application that the boots mode can not adapt to some path roads, city, on Wuhan light rail, Kunming subway and Beijing existing subway circuit; It is little because of the space that requires that manual type takes off boots, on these circuits, becomes a kind of inevitable choice.
It is to adopt the insulation operating handle that the representative type manual type takes off the boots scheme; Rotate initiatively driving lever of pantagraph current collector; And then drive and to take off the boots driving lever and swing to the direction that breaks away from power rail with pantagraph current collector fork that takes off the interlock of boots driving lever and pantagraph current collector piston shoes; After taking off boots and putting in place, initiatively driving lever with take off the boots driving lever and realize mechanical self-latching.Its weak point: though this boots mode of taking off is simple in structure; But need descend near the enterprising line operate in ground power rail under the car; Because of power rail has the high voltage direct current of DC750V even DC1500V, operating personal has the danger of electric shock, locates at platform etc. simultaneously; Because of the restriction in space, can't realize taking off boots.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of pantagraph current collector piston shoes disengaging power rail that makes that realizes safe in operation on the platform that realizes reaching onboard that can adapt to the narrow installing space of train bogie truck also to lock the pantagraph current collector that takes off the boots state voluntarily.
The object of the invention is achieved through following technical proposals: comprise pantagraph current collector main body, swing-bar mechanism, piston shoes and cable; Said swing-bar mechanism comprises fork rotating shaft and bearing, main spring, piston shoes fork, takes off the boots blocking device, the secondary bar of piston shoes; The secondary bar of said piston shoes fork and piston shoes is parallel to each other, all perpendicular to the fork rotating shaft; The said boots blocking device that takes off is installed in the pantagraph current collector main body through taking off boots blocking device bearing, and the afterbody of the secondary bar of said piston shoes falls into and takes off among the boots blocking device; The said boots blocking device that takes off comprises and takes off boots blocking device casing, dead bolt, latch bolt spring, declutch shift shaft, shift fork; Latch bolt spring is installed in the dead bolt afterbody; The tongue body of dead bolt is provided with fork slot, and the head of shift fork falls into fork slot; Shift fork is installed on the declutch shift shaft, and declutch shift shaft is fixed on and takes off in the boots blocking device casing, and declutch shift shaft has at least an end to reach the outside of taking off boots blocking device casing, and an end that stretches out is installed declutch control lever; The afterbody of said shift fork is installed self-locking device.
