Abstract
The invention discloses a superplastic safety height-limiting rod. The superplastic safety height-limiting rod comprises two rigid bases, two superplastic columns, two rigid columns and a superplastic beam. The deformation energy absorption of the superplastic beam and the superplastic columns is achieved and accordingly the self-loss of an impact vehicle is effectively reduced, the damage to a driver and passengers is reduced, meanwhile the secondary damage to other vehicles or pedestrians due to a fracture of the height-limiting rod beam under the action of external impact loads can be avoided. When an impact occurs, most of the impact energy is absorbed due to the plastic deformation of the superplastic beam and the superplastic columns, only the superplastic beam and the superplastic columns need to be replaced after the impact, the other parts of the height-limiting rod do not need to be replaced, and accordingly the use is safe and the replacement operation is simple and convenient.

Detailed description of the invention
The invention discloses a kind of superplasticity safety height-limiting bar, after height-limiting bar is hit, can there is larger plastic strain in the appropriate section of height-limiting bar under impact loading, thereby absorb most of impact energy, vehicle and driver and conductor's thereof degree of injury while having reduced vehicle and height-limiting bar collision.The part replacement that height-limiting bar deforms is convenient, and miscellaneous part can reuse, and uses safety, and it is convenient to change.
In conjunction with Fig. 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 superplasticity crossbeams 4.As shown in Figure 1, one end of every rigid posts 3 is connected with a rigid base 1 by bolt assembly; The other end of rigid posts 3 is further connected with one end of a superplasticity column 2 by bolt assembly; And the other end of every superplasticity column 2 is connected with the flange at the two ends of superplasticity crossbeam 4 respectively accordingly by bolt assembly.
In this preferred embodiment, superplasticity column 2 has two, but is not limited with two.The main body at the middle part of every superplasticity column 2 is the cylindrical structural of hollow, and the two ends of cylindrical structural are connected with flange separately, and every 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%, can absorb the shock loading of vehicle to crossbeam 4 by the plastic strain of self, and brittle fracture can not occur, thereby can avoid other cars two and pedestrian to cause secondary injury.
Similarly, in this preferred embodiment, rigid posts 3 has two, but is not limited with two.The cylindrical structural that the main body that is positioned at middle part of every rigid posts 3 is hollow, the two ends of cylindrical structural are connected with flange separately, and every 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 preferably hard can weld carbon steel, but is not limited to carbon steel.
The cylindrical structural that main part in the middle of superplasticity crossbeam 4 is hollow, 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 the shock loading of vehicle to crossbeam 4 by the plastic strain of self, and can not rupture.
