Chinese patent 201320157520.4 discloses a kind of hand relieving device of rail vehicles foundation brake rigging, comprise traction element and ratchet pin assembly, ratchet pin assembly by its longitudinal movement form with spring energy-storage cylinder in the ratchet cover plate engage or depart from, when it and the ratchet cover plate departs from time alleviate parking brake power; The vertical setting in traction element lower end is also connected with ratchet pin assembly by converting member, and the catenary motion of traction element is converted to the longitudinal movement of ratchet pin assembly by converting member, and traction element upper end is connected with the framework of rail vehicles; Mounting box is connected with cushion block, and mounting box and cushion block form the cavity of accommodating voussoir; Traction element comprises steel rope, and be located at the sleeve pipe of outside, steel rope lower end, sleeve pipe is connected with mounting box, and steel rope lower end is passed sleeve pipe, is connected with voussoir in mounting box, and traction element upper end is provided with adapter plate, and adapter plate is connected with framework by bolt assembly.
The existing core rub proofness pulling relieving apparatus is poor, pulls power little during application, and car is installed bending many, need alerting ability high, mounting pipe bears pressure difference; Simultaneously core only bears pulling force, when causing pulling alleviation hand delay pin can not self-return.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art existence, seek to design a kind of core fastness to rubbing high, mounting pipe bears pressure capability by force, removes after pulling braking and can pull relieving apparatus by the plug-type of return.
To achieve these goals, the technical solution used in the present invention is: one is plug-type pulls relieving apparatus, comprise check plate, threaded connection, core, guide pipe, stationary pipes, raw silk rings flexible pipe, connection pipe, stationary pipes two, connector, described core inside is stainless steel wire, outside is the stainless steel belt of spiral winding, make whole core have rigidity, pulling force and pressure can be born;
Described threaded connection left end is fixedly connected with check plate by nut, two parallel facess of the plate face clamp nut of check plate;
Described guide pipe right-hand member is convex structure, guide pipe right-hand member is rotatingly be locked in stationary pipes left end, stationary pipes right-hand member is connected with raw silk rings flexible pipe, the raw silk rings flexible pipe other end is connected with connection pipe, connection pipe is provided with curve, the curve of connection pipe is fixedly connected with stationary pipes two, and described core runs through guide pipe, stationary pipes, raw silk rings flexible pipe, connection pipe and stationary pipes two by guide pipe left end; Described core one end is connected with threaded connection right-hand member, and the other end is connected with connector.
Preferably, between described threaded connection and guide pipe, be provided with dust protecting cap A, between described stationary pipes two and connector, be provided with dust protecting cap B.
Preferably, lining is arranged with in described raw silk rings flexible pipe.
During use, check plate is connected with the leverage of relieving apparatus, and parking pull bar or parking pin of connector and park brake is connected; By captive nut and pad, to pull relieving apparatus fixing with on car body by plug-type, when core move, stationary pipes, raw silk rings flexible pipe, connection pipe can not move along with core with stationary pipes two and together with move.
Beneficial effect of the present invention is: core rigidity is large, and can bear large load, withstanding corrosion, wear resisting property are good; Can make to park pull bar or park pin return by the plug-type relieving apparatus that pulls after pulling brake off; Pull when alleviating leverage motion and can produce certain pivot angle, guide pipe right-hand member around stationary pipes rotary oscillation certain angle, can adapt to the swing of lever, thus the power preventing threaded connection from bearing because of swing, device long service life, easy to use.
