Although technique scheme can play buffer action to a certain extent, buffer capacity is limited, the damper assembly of stop buffer may be caused to derail, causing safety misadventure when being subject to excessive impulse force.
Utility model content
The purpose of this utility model is to provide a kind of hydraulic cushion slip stop buffer, fundamentally solves the problems such as stop buffer easily derails, poor stability, effectively improves braking friction and the safety of stop buffer.
The technical scheme that the utility model adopts is: this hydraulic cushion slip stop buffer comprises and is slidedly assemblied in the arm assembly on stock rail, energy disperser assembly, the buffer head being arranged on energy disperser assembly front portion, the pressure valve assembly being arranged on energy disperser assembly end and the fuel tank be connected with pressure valve assembly be assemblied on an arm assembly by damper assembly, its technical essential is: described arm assembly comprises two outer support arms, and outer support arm is provided with damper assembly opening and hold down groove.
Be provided with the more than one interior support arm be assemblied on stock rail between described outer support arm, interior support arm is provided with damper assembly opening and hold down groove.
Described interior support arm is two or three.
Described damper assembly comprise be fastened on damper assembly opening both sides for a pair damping frame, somely run through the bolt of damping frame and hold down groove, some nuts for binding bolt.
More than one disk spring is provided with between described bolt and damping frame or between nut and damping frame.
The height of buffer head geometric configuration and width between centers rail level matches with the height of the vehicle coupler geometric configuration be braked and width between centers rail level, damper assembly have employed the damping frame structure mutually fastened, after stop buffer is subject to vehicle crash, the anti-creep beam of stop buffer prevents vehicle from swashing, now stop buffer is subject to hoisting force upwards, further increase the friction force between damper assembly and stock rail, thus improve buffering effect.

Detailed description of the invention
Concrete structure of the present utility model is described in detail according to Fig. 1 ~ 5.For ease of the mounting means of damper assembly is described, in Fig. 1, omit centre portion damper assembly.This hydraulic cushion slip stop buffer comprises and is slidedly assemblied in the arm assembly on stock rail 7, energy disperser assembly 2, the buffer head 1 being arranged on energy disperser assembly 2 front portion, the pressure valve assembly 4 being arranged on energy disperser assembly 2 end and the fuel tank 3 be connected with pressure valve assembly 4 be assemblied on an arm assembly by damper assembly 6.
The structure that energy disperser assembly, buffer head and pressure valve assembly adopt is substantially identical with the content disclosed in patent CN203864709U, pressure valve assembly, be engaged between fuel tank 3 and energy disperser assembly 2, it mainly comprises pressure valve housing, is arranged on the end cap 18 on pressure valve housing 14 top, by the spacing valve body 13 in pressure valve housing 14 of spring 12, body base is provided with valve body aperture 16, be provided with housing aperture 15 bottom pressure valve housing 14, be connected by oil outlet pipe 17 between fuel tank with pressure valve housing.
(the present embodiment is for preferred four for more than two of be arrangeding in parallel for stock rail 7, outermost two is for outer support arm, inner side two for interior support arm to improve the friction force of stop buffer), prop up arm assembly and comprise two symmetrically arranged outer support arms 5 and two symmetrically arranged interior support arms 10, outer support arm 5 and interior support arm 10 are equipped with damper assembly opening 8 and hold down groove 9, and inside and outside each support arm is a corresponding stock rail respectively.Damper assembly 6 comprise be fastened on damper assembly opening 8 both sides for a pair damping frame 21, somely run through the bolt 20 of damping frame 21 and hold down groove 9, some nuts 19 for binding bolt 20, some disk springs 22 be assemblied between bolt 20 and damping frame 21 and between nut 19 and damping frame 21.Damping frame upper end is spacing in damper assembly opening, and middle part is fixed by bolt, nut, and bottom is connected on stock rail.
Buffer head is arcuate structure, and this shape can match with vehicle front, and buffer head front end is provided with anti-creep beam 11, because impulse force is excessive and swash when preventing vehicle collision buffering head, avoids safety misadventure.Meanwhile, because the quantity adding stock rail and support arm effectively improves the bearing capacity of stop buffer, effectively prevent stop buffer derailing.Anti-creep girder construction then can be replaced according to the vehicle of different model accordingly, and this kind of substitute mode belongs to the ordinary skill in the art and select, and no longer elaborates.
The present embodiment is for two interior support arms, usually this structure is almost applicable to rolling stock, but considering, when vehicle tonnage is less for manufacturing cost and damping, adopt the stop buffer of single interior support arm can meet use needs equally, and reduce use cost.And for the higher vehicle of tonnage, if two interior support arms are still difficult to meet use needs, then interior support arm quantity can be increased to three even more than four further.
