The problem of being proposed in technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of damping device for highway bridge, including upper support seat and lower support base, on the lower support base
The first groove of opening up setting is offered, cushion rubber bumper, cushion rubber bumper upper end and upper support seat are provided with the first groove
Downside is fixedly connected, and two the first cavitys are symmetrically offered in the cushion rubber bumper, the first disc spring is equipped with the first cavity；Institute
State and the second cavity is offered at cushion rubber bumper bosom, the second cavity inner bottom part is fixedly connected with the first magnetic pole, the second cavity
Inner top is fixedly connected with the second magnetic pole, is fixedly connected between the first magnetic pole and the second magnetic pole by several springs；Under described
Support base top symmetrically offers the second groove of two opening up settings, and the second groove inner bottom part is fixedly connected with the second dish
Spring, the top of second disc spring are fixedly connected with lead, are oriented to top end with being fixedly connected on the downside of upper support seat.
It is as further program of the utility model：The cushion rubber bumper is highly more than the height of the first groove.
As the utility model, further scheme is：The polarity of first magnetic pole and the second magnetic pole is identical.
As the utility model, further scheme is：The center line phase of the center line of the lead and the second groove
Overlap.
The beneficial effects of the utility model be when upper support seat by downwards in the presence of when, the first disc spring plays buffering and subtracted
The effect of shake；When cushion rubber bumper is under pressure, the second magnetic pole moves downward, then the distance between the first magnetic pole and the second magnetic pole
Shorten, i.e., between repulsive force increase, play a part of bumper and absorbing shock；When lead moves downward, the second disc spring is pressed
Contracting, so as to further have the function that damping.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole

The every other embodiment obtained, belong to the scope of the utility model protection.
Referring to Fig. 1, in the utility model embodiment, a kind of damping device for highway bridge, including upper branch
Seat 10 and lower support base 1 are supportted, the first groove 2 of opening up setting is offered on the lower support base 1, is set in the first groove 2
Cushion rubber bumper 3 is equipped with, the upper end of cushion rubber bumper 3 is fixedly connected with the downside of upper support seat 10, symmetrically offered in the cushion rubber bumper 3
Two the first cavitys 4, the first disc spring 5 is equipped with the first cavity 4, when upper support seat 10 is by the presence of downwards, first
Disc spring 5 plays a part of bumper and absorbing shock；
The second cavity 8 is offered at the bosom of cushion rubber bumper 3, the inner bottom part of the second cavity 8 is fixedly connected with first
Magnetic pole 6, the inner top of the second cavity 8 are fixedly connected with the second magnetic pole 9, pass through several bullets between the first magnetic pole 6 and the second magnetic pole 9
Spring 7 is fixedly connected, and first magnetic pole 6 is identical with the polarity of the second magnetic pole 9, when cushion rubber bumper 3 is under pressure, the second magnetic pole
9 move downward, then the distance between the first magnetic pole 6 and the second magnetic pole 9 shorten, i.e., between repulsive force increase, play buffering and subtract
The effect of shake；
