The specific embodiment
According to Fig. 1 ~ 3, describe the concrete structure of the another kind of embodiment of the utility model in detail.This double-cylinder hydraulic buffering slip stop buffer comprises by damper assembly 5 and is arranged on support arm 3 on stock rail 4, is arranged on water bumper 2 on support arm 3, is arranged on the parts such as buffer head 6 on water bumper 2 and oil storage cylinder 1.Wherein, between damper assembly 5 inside and the rail level of stock rail 4, friction seat and spring plate are housed, by inserting also urgent taper, make laminated spring flexural deformation produce pressure, this pressure makes under Hubei Province and rail head of rail, between edge, to produce friction force between friction seat and rail level, under damper, this friction force is exactly the main braking force that stops runaway vehicle, and damper assembly 5 can increase and decrease quantity as required.Support arm 3 is vertically set on stock rail 4, is provided with the underframe 30 of X-type between two support arms, and support arm 4 is provided with one end and is fixed on the telescopic anti-creep guide rail 29 on buffer head 6, and buffer head 6 is provided with anti-creep portion 28.Anti-creep portion 28 is inverted L shaped structure from the side, and L shaped vertical edge is provided with some fins.Water bumper 2 comprises two low pressure buffer chambeies 15 that are fixed on hydraulic actuating cylinder on support arm 4, are fixed on hydraulic actuating cylinder top, a flow regulating valve assembly 17 being connected with low pressure buffer chamber 15.Flow regulating valve assembly comprises flow regulating valve assembly shell, is arranged on the flow regulating valve kicker 18 in flow regulating valve assembly shell, the valve rod 19 being driven by flow regulating valve kicker 18, and flow regulating valve assembly shell is provided with anti-discharge orifice 20.Each hydraulic actuating cylinder comprises that respectively a cylinder barrel 24, an one end are socketed in the plunger body 10 sliding along cylinder barrel 24 in cylinder barrel 24, and for convenience of production and processing, cylinder barrel is provided with front end cover 13, and cylinder barrel 24 ends are welded with rear side housing 23.Two cylinder barrels 24 are connected with flow regulating valve assembly 17 by threeway 22 respectively.In cylinder barrel 24, be provided with piston rod cover 14, in plunger body 10, be provided with one end and be positioned at the piston rod 11 sliding along piston rod cover 14 along piston rod cover 14.The other end of plunger body 10 is fixed with plunger end cap 7, and buffer head 6 is fixed on plunger end cap 7 outsides, and the other end of plunger end cap 7 inner sides and cylinder barrel 24 is spacing respectively a spring perch 8, is provided with kicker 9 in plunger body.Between cylinder barrel 24 and piston rod cover 14, form high-pressure buffer chamber 25, between low pressure buffer chamber 15 and high-pressure buffer chamber 25, be provided with the throttling passage 16 that connects flow regulating valve assembly 17.
High-pressure buffer is equipped with hydraulic oil in chamber, and due to the incompressibility of hydraulic oil, when cavity pressure surpasses the response pressure of flow regulating valve assembly, valve rod is opened, and hydraulic oil flows into low pressure buffer chamber by throttling passage.According to Hydraulic System Principle, hydraulic oil will do work and generate heat when the gap by flow regulating valve assembly, changes mechanical energy into heat energy.This hydraulic efficiency pressure system is exactly around this principle the kinetic energy of vehicle to be passed to flow regulating valve kicker, and along with kicker is compressed, the kinetic energy of vehicle reduces gradually until plunger stroke ends.By changing the precompressed compression of flow regulating valve kicker, can adjust the cushion effect of hydraulic damping device.
If plunger stroke ends, vehicle does not stop moving, and vehicle energy will be delivered on damper by main frame.When the impulsive force of runaway vehicle is greater than the friction force between damper and rail, stop buffer starts to slide along rail.Damper in the middle of if stop buffer is equipped with, stop buffer slides after a segment distance, and front damper contacts with middle damper, and in the middle of promoting, damper slides thereupon, and horizontal resistance strengthens thereupon; As additional damping device is also housed, stop buffer slides after a segment distance again, and rear damper contacts with additional damping device, promotes successively additional damping device and slides.The a pair of damper of every increase, the total braking force of stop buffer just improves a class.Stop buffer, in the process of sliding, consumes the kinetic energy of runaway vehicle by friction, until vehicle stop moves.Because the total braking force of stop buffer is stepped appearance, increase successively, therefore both can guarantee the larger braking potential of keeping off a car, can effectively protect hitch again.After runaway vehicle coupler leaves buffer head, under the effect of kicker, plunger is overhanging gradually, and now in oil cylinder, space increases and form negative pressure, and the hydraulic oil in fuel tank flows back to oil cylinder by anti-discharge orifice, pipeline, and stop buffer is got back to initial condition.Thereby the impact in the time of can alleviating Vehicular impact stop buffer, thereby improve the strained condition of hitch.
In addition, when car body anti-creep beam 27 collision buffering head 26, tight lock coupler 6 enters buffer head middle part, car body anti-creep beam 27 matches with the fin structure in anti-creep portion 28, anti-creep guide rail 29 is as the stressed fulcrum of anti-creep portion 28, inverted L shaped structure can prevent the motion of car body vertical direction, prevents that derailing event from occurring.
embodiment 2
According to Fig. 4 ~ 6, describe the concrete structure of the another kind of embodiment of the utility model in detail.Its keystone configuration is with embodiment 1, and difference is: 1) support arm and vertical direction are certain inclination angle; 2) anti-creep guide rail is single, and between two cylinder barrels; 3) buffer head front portion is designed to the structure matching with Vehicular body front arc anti-creep beam, and the L shaped structure horizontal edge of inversion of anti-creep portion is short compared with embodiment 1; 4) stock rail is grooved rail.
