Detailed description of the invention
The invention discloses a kind of superplasticity safety height-limiting bar, after height-limiting bar is hit, can be there is larger plastic strain in the appropriate section of height-limiting bar under impact loading, thus absorb most of impact energy, reduces the degree of injury of vehicle and driver and conductor thereof when vehicle and height-limiting bar collide.The part replacement that height-limiting bar deforms is convenient, and miscellaneous part can reuse, use safety, and it is convenient to change.
Composition graphs 1 and Fig. 2, superplasticity safety height-limiting bar according to the present invention comprises two rigid bases, 1, two superplasticity columns, 2, two rigid posts 3 and a superplasticity crossbeam 4.As shown in Figure 1, one end of every root rigid posts 3 is connected with a rigid base 1 by bolt assembly; The other end of rigid posts 3 is connected further by bolt assembly one end with a superplasticity column 2; And the other end of every root superplasticity column 2 by bolt assembly accordingly respectively with the Flange joint at the two ends of superplasticity crossbeam 4.
In the preferred embodiment, superplasticity column 2 has two, but is not limited with two.The main body at the middle part of every root superplasticity column 2 is the cylindrical structural of hollow, and the two ends of cylindrical structural are connected with flange separately, and every root superplasticity column 2 is connected with rigid posts 3 and superplasticity crossbeam 4 respectively by the flange at its two ends.And the material of superplasticity column 2 is superplasticity steel material, the elongation per unit length of this material can reach more than 50%, vehicle can be absorbed to the shock loading of crossbeam 4 by the plastic strain of self, and brittle fracture can not occur, thus can avoid causing secondary injury to other cars two and pedestrian.
Similarly, in the preferred embodiment, rigid posts 3 has two, but is not limited with two.The main body being positioned at middle part of every root rigid posts 3 is the cylindrical structural of hollow, and the two ends of cylindrical structural are connected with flange separately, and every root rigid posts 3 is connected with superplasticity column 2 and rigid base 1 respectively by the flange at its two ends.And the material of rigid posts 3 is steel, its deformation load is far above superplasticity column, and preferred hard can weld carbon steel, but is not limited to carbon steel.
Main part in the middle of superplasticity crossbeam 4 is the cylindrical structural of hollow, and its two ends are connected with flange, and superplasticity crossbeam 4 is connected with two superplasticity columns 2 respectively by the flange at its two ends.And the material of superplasticity crossbeam 4 is superplasticity steel material, this kind of material bending strength in horizontal plane, much smaller than the bending strength in vertical plane, can absorb vehicle to the shock loading of crossbeam 4 by the plastic strain of self, and can not rupture.
In addition, above-mentioned flange arrangement and bolt assembly are the known technology of those skilled in the art.Wherein, bolt assembly comprises bolt, nut and pad.Flange is plectane (or other shapes) structure, it is provided with equably four through holes, for correspondingly being coupled together by the flange on all parts by bolt.
