Part is connected with ratchet pin assemblies, and the catenary motion of traction element is converted to the lengthwise movement of ratchet pin assemblies by converting member,
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 accommodating wedge
The cavity of block；Traction element includes steel wire rope, and located at the sleeve pipe outside steel wire rope lower end, sleeve pipe is connected with mounting box, steel wire rope
Lower end pass through sleeve pipe, is connected with voussoir in mounting box, traction element upper end is provided with installing plate, installing plate pass through bolt assembly and
Framework connects.
Existing pull alleviate device core rub proofness poor, the power that pulls during application is little, on car install bend many, need spirit
Activity is high, and it is poor that installing pipe bears pressure；Core is solely subjected to pulling force simultaneously, and leading to pull the slow pin of handss during alleviation can not return automatically
Position.
Content of the invention
It is an object of the invention to the shortcoming overcoming prior art to exist, seek to design a kind of core abrasion resistance height, install
Pipe bears pressure capability by force, releases and can pull alleviation device by the plug-type of return after pulling braking.
To achieve these goals, the technical solution used in the present invention is: one kind is plug-type to pull alleviation device, including anti-
Deals, nipple, core, guide pipe, fixing pipe, raw silk rings flexible pipe, connecting tube, fixing pipe two, union joint, inside described core
For stainless steel silk, the outside stainless steel belt for spiral winding, make whole core have rigidity, pulling force and pressure can be born；
Described nipple left end is fixedly connected with locking plate by nut, puts down for two of the plate face binding nut of locking plate
Row face；
Described guide pipe right-hand member is convex structure, preferably hemispherical dome structure, and guide pipe right-hand member is in rotatable locking
In fixing pipe left end, fixing pipe right-hand member is hose connection with raw silk rings, and the raw silk rings flexible pipe other end is connected with connecting tube, and connecting tube is provided with
Bending section, the bending section of connecting tube is fixedly connected with fixing pipe two, and described core runs through guide pipe by guide pipe left end, consolidates
Fixed tube, raw silk rings flexible pipe, connecting tube and fixing pipe two；Described core one end is connected with nipple right-hand member, the other end and union joint
Connect.
Preferably, it is provided with dirt-proof boot a between described nipple and guide pipe, between described fixing pipe two and union joint
It is provided with dirt-proof boot b.
Preferably, it is arranged with bushing in described raw silk rings flexible pipe.
During use, locking plate is connected with the leverage alleviating device, union joint and park brake park pull bar or
Person parks pin connection；Pull on alleviation device fixation and car body by fixing nut and pad by plug-type, when so that core is moved,
Fixing pipe, raw silk rings flexible pipe, connecting tube and fixing pipe two will not with core motion together with move.
The invention has the benefit that for being stainless steel band outside stainless steel silk inside core, not only there is bendable folding endurance but also
There is greater stiffness, big load can be born, corrosion-resistant, anti-wear performance is good；Push-and-pull can be passed through after pulling releasing braking
Formula pulls alleviation device and makes to park pull bar or park pin return；Certain pivot angle can be produced when pulling alleviation leverage motion,
Guide pipe right-hand member around fixing pipe rotary oscillation certain angle, can adapt to the swing of lever, thus preventing nipple because swinging
And the power born, device long service life, easy to use.
