Description
Technical field:
This utility model relates to traffic safety equipment technical field, is specifically related to a kind of anticollision device, collision-prevention device for bridge on highway.
Background technology:
Fast development along with public transport, bridge is built in a large number owing to it has the feature such as leap rivers and shortening highway mileage, the bridge used the most on a highway, in order to Improving Expressway bridge get on the car travel safety, bridge on highway can use anticollision device, collision-prevention device, traditional anticollision device, collision-prevention device simple in construction, is mainly assisted the impact slowing down vehicle by the filling padded coaming of portion in the enclosure, but this kind of anticollision device, collision-prevention device crashworthiness is limited, there is bigger potential safety hazard.
Utility model content:
The purpose of this utility model is the defect for prior art and deficiency, it is provided that a kind of anticollision device, collision-prevention device for bridge on highway, its simple in construction, novel in design, is cooperated by multi-buffer device, successively absorbs the strength of shock, more safe and reliable.
In order to solve the problem existing for background technology, a kind of anticollision device, collision-prevention device for bridge on highway of the present utility model, it comprises firm banking, rubber seal shell, snubber contact face, one-level elastic buffering mechanism, two grades of elastic buffering mechanisms, three grades of elastic buffering mechanisms, foam insert；The upper end of described firm banking is provided with rubber seal shell, snubber contact face it is provided with on rubber seal shell, rubber seal shell be internally provided with one-level elastic buffering mechanism, the back of one-level elastic buffering mechanism is provided with two grades of elastic buffering mechanisms, and the both sides, lower end of two grades of elastic buffering mechanisms are provided with a pair three grades of elastic buffering mechanisms；Described one-level elastic buffering mechanism, between two grades of elastic buffering mechanisms, three grades of elastic buffering mechanisms, it is filled with foam insert.
As preferably, described snubber contact face is in series by several round rubber balls, connects by connector is fixing between adjacent round rubber ball.
As preferably, described round rubber ball is internally provided with arc spring leaf.
Compared with prior art, the beneficial effects of the utility model are: it uses three grades of buffer unit effects of cooperating, the moment impact strength of automobile of gradually decaying, it is to avoid clash into and the facility that destroys a bridge, colleague uses elastomeric material to avoid very stiff and demanding, reduces and clashes into harm.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation in this utility model snubber contact face 3.
Description of reference numerals: firm banking 1, rubber seal shell 2, snubber contact face 3, one-level elastic buffering mechanism 4, two grades of elastic buffering mechanisms 5, three grades of elastic buffering mechanisms 6, foam insert 7, round rubber ball 8, connector 9, arc spring leafs 10.
Detailed description of the invention:
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1 and Figure 2, this detailed description of the invention adopts the following technical scheme that it comprises firm banking 1, rubber seal shell 2, snubber contact face 3, one-level elastic buffering mechanism 4, two grades of elastic buffering mechanisms 5, three grades of elastic buffering mechanisms 6, foam insert 7；The upper end of described firm banking 1 is provided with rubber seal shell 2, snubber contact face 3 it is provided with on rubber seal shell 2, rubber seal shell 2 be internally provided with one-level elastic buffering mechanism 4, the back of one-level elastic buffering mechanism 4 is provided with two grades of elastic buffering mechanisms 5, and the both sides, lower end of two grades of elastic buffering mechanisms 5 are provided with a pair three grades of elastic buffering mechanisms 6；It is filled with foam insert 7 between described one-level elastic buffering mechanism 5, three grades of elastic buffering mechanisms 6 of 4, two grades of elastic buffering mechanisms.
As preferably, described snubber contact face 3 is in series by several round rubber balls 8, connects by connector 9 is fixing between adjacent round rubber ball 8.
As preferably, described round rubber ball 8 is internally provided with arc spring leaf 10.
The operation principle of this detailed description of the invention is: when automobile impacting to preventer, first car body contacts with snubber contact face 3, and snubber contact face 3 uses soft rubber to make, it is to avoid very stiff and demanding；Then the impact force of moment is absorbed by one-level elastic buffering mechanism 4, one-level elastic buffering mechanism 4 is touched two grades of elastic buffering mechanisms 5 by the compression inward of impact force, subsequently two grades of elastic buffering mechanisms 5 are oppressed three grades of elastic buffering mechanisms 6 together and impact force are fully absorbed with one-level elastic buffering mechanism 4, more safe and reliable.
Although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
