Abstract
The utility model relates to a fixed multi-buffer car stopper, which comprises a steel foundation embedded part, a car stopper main frame, a spring assembly, a hydraulic-gas buffer and a ram assembly part, wherein the car stopper main frame is fixedly connected with the foundation embedded part through a bolt; and the ram assembly part, the hydraulic-gas buffer and the spring assembly connected in sequence are arranged on the car stopper main frame. The car stopper is provided with a hydraulic-gas buffer mode and a spring buffer mode, so that the braking force and the energy absorbing capacity of the car stopper are greatly increased, the problems of low kinetic energy absorbing capacity and small braking force in small space are solved, and the accidents can be effectively reduced.
Description
Technical field
The utility model relates to the guideway vehicle stop buffer, is specifically related to fixed type multi-buffer stop buffer, is applicable to the track end safety precautions such as different kinds of railways, subway, is particularly useful for the motor train unit track end.
Background technology
At present the guideway vehicle of railway and city underground generally adopts " fixed type keep off a car device " and " sliding stop buffer " as the protective device of line terminal.Sliding stop buffer needs approximately 30 meters skidding distances, takes up room large, and use cost is too high; The fixed type device of keeping off a car, single-stage buffering only, exist braking potential low, absorb the defective such as kinetic energy scarce capacity.
The utility model content
In view of this, the purpose of this utility model is for deficiency of the prior art, a kind of fixed type multi-buffer stop buffer is provided, can make up the domestic and international similar fixed type problem that the device braking potential is low, absorb the kinetic energy scarce capacity of keeping off a car, solved and realized in little space that large kinetic energy absorbs, large demand braking force problem, effectively minimizing accident occurs.
For completing above-mentioned purpose, the technical solution adopted in the utility model is: fixed type multi-buffer stop buffer, comprise steel structure ground built-in fitting, stop buffer body frame, spring assembly, hydro-pneumatic buffer and the assembly parts of raming, the stop buffer body frame is captiveed joint with the ground built-in fitting by bolt, is provided with the assembly parts of raming, hydro-pneumatic buffer and the spring assembly that connect successively on the stop buffer body frame.
Further, the compression distance of described hydro-pneumatic buffer is 600mm.
Compared with prior art, of the present utility model having the following advantages: 1. have gas-liquid buffering and two kinds of buffering methods of spring buffer, greatly improved braking force and the energy-absorbing power of stop buffer, and had auto-reset function, can realize in little space that large kinetic energy absorbs; 2. adopt the high tensile steel plate welding, unit design is reasonable, and is connected with hitch is perfect, when having an accident, guarantees that vehicle body is not fragile, the inertial impaction of effectively bearing errant vehicle.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. ground built-in fitting, 2. stop buffer body frame, 3. spring assembly, 4. hydro-pneumatic buffer, the assembly parts of 5. raming is 6. ramed, 7. wire rope clip, 8. steel rope.
The specific embodiment
Fixed type multi-buffer stop buffer as shown in Figure 1 comprises steel structure ground built-in fitting 1, stop buffer body frame 2, spring assembly 3, hydro-pneumatic buffer 4 and the assembly parts 5 of raming.Stop buffer body frame 2 is captiveed joint with ground built-in fitting 1 by bolt, and impact that stop buffer bears is passed on ground.Be provided with the assembly parts 5 of raming, hydro-pneumatic buffer 4 and the spring assembly 3 that connect successively on stop buffer body frame 2.The assembly parts 5 of raming can bear the inertial impaction of errant vehicle, and the inertia kinetic energy of errant vehicle is passed to hydro-pneumatic buffer 4 and the common locomotive kinetic energy that absorbs of spring assembly 3.The rum point of stop buffer is hitch, guarantees that the body part of errant vehicle is injury-free, therefore is provided with on the assembly parts 5 of raming and rams 6, and ram 6 shape, height are complementary from the hitch of different CRH model motor train unit.Ram 6 by wire rope clip 7 connecting steel wire ropes 8, realize being connected with stop buffer body frame 2.The compression distance of described hydro-pneumatic buffer 4 is 600mm.The train slipping accident occurring, the utility model can make vehicle safety stop, and vehicle body and stop buffer are excellent, and the accident of stopping occurs.
The above specific embodiment only is used for explanation the utility model, but not is used for limiting the utility model, and the equivalent variations that those skilled in the art carry out above-described embodiment, replacement are all within the claim protection domain.
