Detailed Description

The present invention will be described in further detail with reference to the following examples and drawings, but the embodiments of the present invention are not limited thereto.

Referring to fig. 1, a bridge protection fence is formed by arranging and fixing a plurality of groups of protection fence bodies with the same structure at the edge of a bridge in a straight line shape, wherein each single group of protection fence body comprises three bases 1 arranged at intervals along a straight line and support columns 2 fixedly arranged on the bases 1.

The support columns 2 are of a cylindrical structure with a square horizontal section, and the three support columns 2 are horizontally fixed with the supporting beams 3 connected with the top ends of the support columns 2. Wherein every support column 2 all is equipped with support frame 4 that is used for strengthening the rail guard on being located the vertical lateral wall of bridge border one side. The support frame 4 is composed of two support rods 5 (see fig. 3), one ends of the two support rods 5 are fixedly connected to the side walls of the support columns 2, the rod bodies incline downwards, the second ends of the rod bodies are fixedly connected to the bridge floor, and meanwhile, a certain included angle is formed between the rod bodies of the two support rods 5. The arrangement of the support frame 4 can enable the guard railing and the bridge to be fixed more stably.

In order to effectively reduce the collision degree of the guard rails and help the vehicles to adjust the direction so as to reduce the risk that the vehicles rush out of a bridge when the vehicles are out of control and deviate from a road and impact on the guard rails, each group of guard rails is provided with a buffer device. The buffer device comprises buffer railings 6 arranged between the support columns 2 and used for reducing the collision degree and rotating guide rollers 7 arranged on the buffer railings 6 and used for helping the out-of-control vehicle to adjust the direction.

Referring to fig. 2, set up the mounting groove 8 that runs through support column 2 along the perpendicular every support column 2's of while direction on the cylinder of three support column 2, three support column 2 is passed through to buffering railing 6 through the 8 levels of mounting groove on every support column 2, and the width of mounting groove 8 is greater than the width of buffering railing 6, thereby make have the space that can make buffering railing 6 horizontal migration in the mounting groove 8, be equipped with the buffer spring 9 that is used for buffering railing 6 in the mounting groove 8 of every support column 2 simultaneously, buffer spring 9 is the level and perpendicular to buffering railing 6 sets up in mounting groove 8, its one end fixed connection is at the inner wall of mounting groove 8, second end fixed connection is on the outer wall of buffering railing 6, and the both sides of the 6 body of rod of buffering railing all are equipped with buffer. Receive the collision back when buffering railing 6, can be in the mounting groove 8 horizontal migration in three support column 2 and make the buffer spring 9 of buffering railing 6 both sides take place deformation to absorb partial kinetic energy, reach the cushioning effect. Meanwhile, two groups of buffer railings 6 which are positioned at different heights are arranged between the supporting columns 2 for absorbing more kinetic energy so as to obviously reduce collision loss.

Referring to fig. 1, a fixing table 10 for installing a rotating guide roller 7 is arranged between an upper group of buffer railings 6 and a lower group of buffer railings 6 between adjacent support columns 2 in the guard fence, the fixing table 10 is vertically arranged, through holes for the buffer railings 6 to pass through are formed in the upper end and the lower end of the fixing table, and the two groups of buffer railings 6 are fixedly connected with the inner walls of the through holes while passing through the through holes in the upper end and the lower end of the fixing table 10. The rotating guide roller 7 is arranged on the vertical inner wall of the fixed platform 10 close to the inner side of the bridge.

Referring to fig. 1 and 4, four sets of fixing seats 11 for mounting the rotating guide roller 7 are fixedly mounted on the vertical side wall of the fixing table 10 close to the inner side of the bridge, and each set of fixing seats 11 is two fixing seats 11 respectively mounted at the upper end and the lower end of the side wall of the fixing table 10. Fixing base 11 is the setting of perpendicular to fixed station 10 lateral walls, and circular fixed slot 12 has all been seted up to 11 diapalls of fixing base that lie in the lateral wall top simultaneously and the 11 roof of fixing base that lie in the lateral wall below, and fixed mounting has rolling bearing 13 in the fixed slot 12. The upper end and the lower end of the rotating guide roller 7 are fixedly arranged in a rotating bearing 13 in the fixed groove 12, so that the rotating guide roller 7 is rotatably arranged on the side wall of the fixed table 10. In order to make the rotating guide rollers 7 have certain capacity of resisting collision, a layer of polyurethane material is sleeved on the rod body of each rotating guide roller 7.

When a vehicle out of control on a bridge changes the way and collides with a bridge guard rail at the edge of the bridge, the vehicle collides with the side wall of a fixed table 10 of the guard rail, the fixed table 10 drives a buffer rail 6 to move inwards after being impacted, and buffer springs 9 arranged at two sides of the buffer rail 6 can absorb part of the kinetic energy of the vehicle, so that the collision degree is reduced; meanwhile, after the vehicle contacts the fixed table 10, the vehicle slides along the rotating guide roller 7 on the side wall of the fixed table 10, so that the collision direction of the vehicle is changed to a certain extent, and the vehicle head can be helped to adjust the direction of the bridge road while a part of collision force is removed.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
