According to the invention, the four corners of the base are provided with the shock absorption feet, so that part of energy generated by irregular vibration can be absorbed, the shock absorbers are arranged on the support blocks, and the supporting springs are arranged on the outer sides of the shock absorbers, so that the energy generated by the vibration of the mechanism in the vertical direction can be absorbed and buffered to the shock absorption feet, and the stability of the rail transit mechanism in operation is improved.
Description
Technical Field
The invention relates to a damping device, in particular to a damping device for rail transit.
Background
With the continuous development of rail transit, people have higher requirements on the comfort level of riding, the shock absorber solves the problem, and the shock absorber, also called a shock absorber, is used for absorbing and buffering the shock in irregular directions during the running of a vehicle, so that the comfort level of passengers is improved. Common shock absorbers include hydraulic shock absorbers, which are further classified into hydraulic shock absorbers and two-way shock absorbers. Through the arrangement of the hydraulic cylinder and the piston rod which reciprocates in the cylinder, hydraulic oil is arranged in the cylinder, and when the piston valve reciprocates, a buffering force is generated to play a role in absorbing vibration. The prior art shock absorbers for traffic are generally single or paired and cannot smoothly cope with flexible and variable working environments.
Disclosure of Invention
The purpose of the invention is as follows: the utility model provides a damping device for track traffic, through setting up the shock attenuation lower margin and installing four bumper shock absorbers and damping spring to solve the above-mentioned problem that prior art exists.
The technical scheme is as follows: the utility model provides a damping device for track traffic, characterized by includes:
the base, fix the shock attenuation lower margin in base four corners, parallel mount are at a pair of support piece on the base, install bumper shock absorber on the support piece, set up the supporting spring in the bumper shock absorber outside, one side of supporting spring is fixed on the support piece, and the opposite side links to each other with the clamp plate.
In a further embodiment, the shock absorption anchor is made of rubber and is used for reducing the impact of a load on the device and absorbing energy generated by part of irregular vibration;
in a further embodiment, the shock absorbers are hydraulic shock absorbers, and two, four in total, are mounted on each support block and used for absorbing and buffering energy generated by vibration to shock absorption feet;
in a further embodiment, the supporting spring is a metal coil spring, which can bear a large load;
in a further embodiment, the outer wall of the shock absorber is provided with a spring seat, and the supporting spring is arranged on the spring seat, so that the spring is more conveniently mounted on the shock absorber.
In a further embodiment, a damper is arranged inside the shock absorber and used for increasing damping and improving shock absorption strength.
Advantageous effects
The invention relates to a damping device for rail transit, which has the following beneficial effects: the device includes the base, and the shock attenuation lower margin is installed at four angles below the base, the shock attenuation lower margin is the rubber material, can absorb certain vibrations. Two support blocks which are installed in parallel are arranged above the base, two dampers are installed on each support block, the number of the dampers is four, and a supporting spring is arranged on the outer side of each damper, so that vibration in all directions can be absorbed, and the running stability of the vehicle is further improved.

Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the invention.
The utility model provides a damping device for track traffic, includes base 2, shock attenuation lower margin 1, support piece 3, supporting spring 4, bumper shock absorber 5 and clamp plate 6, shock attenuation lower margin 1 is installed in the four corners of 2 lower extremes of base, shock attenuation lower margin 1 is the rubber material, can absorb partial vibrations, plays stabilizing mean's effect, install a pair of parallel support piece 3 of placing on the base 2, install two bumper shock absorbers 5 on every support piece 3, bumper shock absorber 5 is the fluid pressure type bumper shock absorber, and the inside is equipped with attenuator 8, 5 lower extremes of bumper shock absorber are equipped with spring holder 7, supporting spring 4 sets up on spring holder 7 for the installation of spring on bumper shock absorber 5 is more convenient. One side of the supporting spring 4 is fixed on the spring seat 7, and the other side is connected with the pressing plate 6. The shock absorption device is composed of four shock absorbers 5, each shock absorber 5 is sleeved with a supporting spring 4, when a vehicle bumps, energy generated by shock is firstly transmitted to a pressing plate 6, the shock is uniformly dispersed by the pressing plate 6 and then transmitted to the four shock absorbers 5, the shock absorbers 5 absorb the shock, an internal damper 8 is driven to move up and down, the supporting springs 4 are driven to move up and down, and a further buffering effect is achieved.
As noted above, while the present invention has been shown and described with reference to certain preferred embodiments, it is not to be construed as limited thereto. Various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
