FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of the limiting device of the present invention;

fig. 3 is a schematic view of part a of the present invention.

In the figure: the support comprises a support body 1, a bearing support 2, a gravity assembly 3, a bridge deck support 4, a clamping groove 5, a limiting groove 6, a limiting device 7, an arc-shaped shock absorber 8, a bridge deck 9, a shock absorption assembly 10, a fixer 101, a limiting rod 102, a speed reducing ball 103, an a01 shock absorption ball, an a02 telescopic rod and an a03 buffering support.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, fig. 2 and fig. 3, the present invention provides a technical solution: the utility model provides a bridge device based on convertible shock-absorbing structure of high performance steel fibre concrete, includes support body 1, damper 10 and stop device 7, its characterized in that: the support body comprises a bearing support 2 and a bridge deck support 4, the damping assembly comprises an arc-shaped damper 8 and a gravity assembly 3, the arc-shaped damper 8 is located between the bearing support 2 and the bridge deck support 4, one end of the arc-shaped damper 8 is connected with one end of the bearing support 2, the other end of the arc-shaped damper is connected with the bridge deck support 4 through the gravity assembly 3, the arc-shaped damper 8 can slide relative to the bridge deck support 4, and the limiting device 7 is fixedly mounted on the upper surface of the bridge deck support 4;

under normal conditions, arc bumper shock absorber 8 through the gravity subassembly with bridge floor support 4 is connected, and is right when the bridge floor during certain power of gravity subassembly 3 production, arc bumper shock absorber 8 can relative slip, open absorbing effect, give on the contrary ground during the power that arc bumper shock absorber 8 should, the gravity subassembly has certain cushioning effect to realize the antidetonation effect of conversion card.
