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 Embodiment.

Reference picture 1-2, a kind of Collison fence for bridge, including spandrel girder 1, the top of spandrel girder 1 are provided with bridge, the edge of spandrel girder 1 The direction of bridge span is fixedly connected in the bottom outer wall of bridge, and the quantity of spandrel girder 1 is two, and two spandrel girders 1 are symmetrical It is arranged in bridge bottom outer wall, buffer unit 2 is fixedly connected with the outer wall of spandrel girder 1, buffer unit 2 includes being welded in holding Bottom plate 3 in the side wall of weight beam 1, bottom plate 3 are fixed with reaction box 4, point are provided with reaction box 4 in the side wall away from spandrel girder 1 Fiery device, the outer cover of igniter are provided with air bag 5, reactant, the structure and safe automobile air bag of air bag 5 are provided with air bag 5 Structure is identical, and air bag 5 is fixedly connected with portable plate 6 on the side outer wall away from igniter, and portable plate 6 is slidably connected to reaction On the inwall of box 4, reaction box 4 is fixedly connected with limited block, limited block and the phase of sliding panel 6 on one end inwall away from air bag 5 Match somebody with somebody, portable plate 6 is fixedly connected with bearing bar 7 on the side outer wall away from air bag 5, one end of bearing bar 7 passes through the interior of reaction box 4 Wall is simultaneously extended to outside reaction box 4, and bearing bar 7 is slidably connected in reaction box 4 close to one end of portable plate 6, and bearing bar 7 is remote It is fixed on the both sides outer wall of block 8 to connect from being fixedly connected with the block 8 that is be arranged in parallel with bridge in a side wall of portable plate 6 Cushion is connected to, cushion is covered in around bottom plate 3, the damping rubber that cushion includes the stage clip of annular and is covered in around stage clip Rubber cushion, the one end of block 8 away from bearing bar 7 are fixedly connected with buffer 9, and a side wall of the buffer 9 away from block 8 is provided with slow Rush block, buffer stopper is BHD3.0 × 2-FF-C type cushion pads, and buffer 9 is BIH-5DXLL type hydraulic bjuffers, buffer unit 2 Quantity be ten to 20, multiple buffer units 2 are equidistantly distributed on the outer wall of the same side of spandrel girder 1 in tapered, and position It is more than the length of the reaction box 4 positioned at the both sides of spandrel girder 1 successively in the length of the reaction box 4 at the middle part of spandrel girder 1, passes through buffering Pad, the design of buffer 9 make baffle plate 8 form preliminary buffering to the impact of hull, by air bag 5 and bearing bar 7 to hull Impulse force forms second and buffered again, the impact of hull is evenly distributed on spandrel girder 1 by the design of multiple buffers so that Bridge entirety stress, multi-buffer act on the impulsive force for effectively reducing hull, and protection bridge is without prejudice, extends bridge Service life.

In the utility model, when hull strikes baffle plate 8, cushion pad is first subjected to the impact of hull, then buffering The impact that the buffer dig pass of device 9 comes, when impact is larger, the igniter in reaction box 4 starts, and air bag 5 expands, living Dynamic plate 6 drives bearing bar 7 to be moved towards the side away from spandrel girder 1, so that baffle plate 8 applies reverse thrust to hull, enters The impulsive contact force of the counteracting hull of one step, when hull impulsive contact force is smaller, the block 8 contacted with hull is towards close to the one of spandrel girder 1 Side is moved, and the active force being subject to is passed to one side shield 8 by the block 8 contacted with hull, is uniformly distributed active force, when Hull continue towards bridge move when, because multiple baffle plates 8 are in tapered distribution, the fore portion run-off the straight of hull and towards bridge side Being moved at edge, angle is gradually reduced between straight line residing for straight line residing for hull and bridge, and hull side wall contacts with multiple baffle plates 8, It is uniformly distributed impact.

It is described above, the only preferable embodiment of the utility model, but the scope of protection of the utility model is not This is confined to, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality New technical scheme and its utility model design are subject to equivalent substitution or change, should all cover in protection model of the present utility model Within enclosing.
