As a further limitation of the technical scheme, the center of the upper side of each connecting rod is fixedly connected with a fixed column, the upper end of each fixed column is respectively hinged with one end of a swinging rod, the other ends of the two swinging rods are both hinged with two ends of a limiting block, the center of one side of the limiting block is fixedly connected with a telescopic rod of a gas spring, and a shell of the gas spring is fixed on the upper side of the arched bracket.
As a further limitation of the technical scheme, the lower ends of the two sides of the arch-shaped support are respectively fixedly connected with a mounting block, and four corners of the mounting block are respectively provided with mounting holes.
As a further limitation of the technical scheme, the anti-collision plate is long-strip-shaped, and the surface of the anti-collision plate perpendicular to the ground is an arc-shaped surface.
As a further limitation of the technical scheme, the surface of the anti-collision plate is coated with a rubber layer.
Compared with the prior art, the utility model has the advantages and positive effects that:
The arch support is adopted as a basic structure, so that the arch support can be conveniently installed on the ground or other structures, can move according to the needs, and is suitable for different road or bridge conditions;
The connecting rod is provided with the gas spring and the limiting block, so that the anti-collision plate can automatically recover to the original state by means of the elasticity of the gas spring after collision, and the limiting block can limit the swing range of the anti-collision plate to avoid excessive deformation;
The anti-collision plate is made into a long strip shape, the surface of the anti-collision plate perpendicular to the ground is an arc surface, and the surface of the anti-collision plate is coated with a rubber layer, so that the buffering effect and the wear resistance of the anti-collision plate are improved.

FIG. 2 is a schematic perspective view of a second embodiment of the present utility model;
fig. 3 is a schematic perspective view of a third embodiment of the present utility model.
In the figure:
1. the anti-collision device comprises an arch support, 2, an anti-collision plate, 3, a connecting rod, 4, a Z-shaped rod, 5, a mounting block, 6, a mounting hole, 7, a fixing column, 8, a swinging rod, 9, a gas spring, 10, a limiting block, 11 and a fixing block.
Detailed Description
The utility model is further described below with reference to fig. 1-3 and the embodiments.
Embodiment one: the utility model provides a movable impact-resistant guardrail, which comprises an arch support 1, wherein two sides of the arch support 1 are respectively and fixedly connected with a group of uniformly arranged fixed blocks 11, and each fixed block 11 is respectively hinged with one end of a Z-shaped rod 4;
The lower side of one end of each Z-shaped rod 4 is fixedly connected with the upper end of the anti-collision plate 2.
The other end of each group of Z-shaped rods 4 is hinged with one end of a connecting rod 3.
The center of the upper side of each connecting rod 3 is fixedly connected with a fixed column 7 respectively, the upper end of each fixed column 7 is hinged with one end of a swinging rod 8 respectively, the other ends of the two swinging rods 8 are hinged with two ends of a limiting block 10 respectively, the center of one side of the limiting block 10 is fixedly connected with a telescopic rod of a gas spring 9, and a shell of the gas spring 9 is fixed on the upper side of the arched bracket 1.
