Description
Technical field
This utility model is related to hydraulic means field, especially a kind of hydraulic cushion dress for hydraulic buffer stopper
Put.
Background technology
Hydraulic buffer stopper has been arranged on gauge lines blind siding terminal, is to prevent that vehicle is surprisingly out of control to go out line terminal
Safety equipment, can effectively prevent casualties and vehicle and other facilities damage it is ensured that operation security.
Existing hydraulic buffer stopper is typically made up of shock guide, hydraulic bjuffer, hydraulic bjuffer basis, its
Middle hydraulic bjuffer is the critical component of car lug.Conventional hydraulic buffer typically more adopts steel spring as back-moving spring, but
When mechanical system is often subject to toward renaturation impact, the fatigue phenomenon of steel spring will greatly reduce the use longevity of hydraulic bjuffer
Life.Meanwhile, in order to ensure the performance of hydraulic bjuffer, the area of its throttle orifice needs according to certain rule change, just can ensure that
Its cushion effect and buffer speed generally maintain constant, but during using this embodiment, the processing of above-mentioned throttle orifice, have higher
Manufacture difficulty, relatively costly, be unsuitable for all enterprises and produce.
Utility model content

A kind of hydraulic damping device for hydraulic buffer stopper of processing.
This utility model adopts the technical scheme that：
A kind of hydraulic damping device for hydraulic buffer stopper it is characterised in that：Including an outer cylinder, this outer cylinder
Rearward end cylinder bottom is installed, described cylinder bottom be located at cylinder body outside end face in a cylinder guide is installed with by nut
Rearward end, the leading section of this cylinder guide is located inside described outer cylinder, in the front end of this cylinder guide and outer cylinder
It is set with an inner cylinder tube, this inner cylinder tube stretches out along the front end of outer cylinder, described inner cylinder tube is located at the end outside outer cylinder between wall
Portion is provided with cylinder head, and this cylinder head forms a seal cavity, described annular seal space with the leading section of inner cylinder tube inwall and cylinder guide
Radially it is sealed and installed with a separator piston in vivo, seal cavity is divided into nitrogen chamber and oil pressure one Room by this separator piston,
The space being formed between described cylinder guide outer wall and outer cylinder inwall is oil pressure two Room, described oil pressure one Room and oil pressure two Room
It is connected, the end outside described cylinder head is provided with one and rams.
And, the length of described inner cylinder tube is less than the length of outer cylinder.
And, described cylinder guide side wall is formed with the uniform oil groove of gradient.
Advantage of the present utility model and good effect are：
In this utility model, cylinder guide and separator piston and cylinder head match, by within inner cylinder tube and outer cylinder
Cavity is isolated into nitrogen chamber, oil pressure one Room and oil pressure two Room, and the nitrogen chamber cooperation being built-in with nitrogen is ramed and separator piston replacement
Original steel spring, not only can avoid the problem of fatigue failure moreover it is possible to realize no wearing away work, improve the service life of device,
Reduce maintenance capacity, in addition, said structure and outer cylinder form an entirety, not only compact conformation, also form one and entirely seal
The structure closed, only needs regular injecting oil and gas, need not be separately provided oil storage fuel tank and valve group, both be easy to maintenance, reduced cost again,
In addition using separator piston by Oil-gas Separation so that the installation of device is not limited by environment, can level, vertically or have
Constant inclination rake angle；The length of inner cylinder body is less than the length of outer cylinder body, can make full use of the cushion space of inner cylinder body；Cylinder guide
The oil groove that sidewall slope is made, during piston movement, can make orifice size between oil pressure one Room and oil pressure two Room by
Certain rule change is so that cushion effect and buffering velocity-stabilization export thus reaching buffering effect, compared to original throttle orifice
Manufacture, technology is more simple, and cost is more cheap.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to embodiment, this utility model is further illustrated, following embodiments are illustrative, be not limited
It is impossible to limit protection domain of the present utility model with following embodiments.
A kind of hydraulic damping device for hydraulic buffer stopper, innovation of the present utility model is, including an outer shell
Cylinder 5, the rearward end of this outer cylinder is provided with cylinder bottom 7, and described cylinder bottom is located in the end face outside cylinder body and is fixedly mounted by nut 8
There is the rearward end of a cylinder guide 6, the leading section of this cylinder guide is located inside described outer cylinder, this cylinder guide
It is set with an inner cylinder tube 4, this inner cylinder tube stretches out along the front end of outer cylinder, and described inner cylinder tube is located between front end and outer cylinder inwall
End outside outer cylinder is provided with cylinder head 13, and this cylinder head forms a sealing with the leading section of inner cylinder tube inwall and cylinder guide
Cavity, is radially sealed and installed with a separator piston 3 in described seal cavity, seal cavity is divided into nitrogen by this separator piston
Air chamber 2 and oil pressure one Room 11, the space being formed between described cylinder guide outer wall and outer cylinder inwall is oil pressure two Room 9, institute
State oil pressure one Room to be connected with oil pressure two Room, the end outside described cylinder head is provided with one and rams 1.
In the present embodiment, for playing steadily sufficiently buffering effect, the length of described inner cylinder tube is less than the length of outer cylinder；
