Embodiment Construction

[0019] The improved superplastic safety height-limiting rod according to the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The invention discloses an improved superplastic safety height-limiting rod. In the structure of the invention, since the material of the rod is superplastic steel, the buffer beam is an aluminum honeycomb structure, and the two ends of the rod are respectively rotatably connected to the rod The base and the column, and one end of the column is rotatably connected to the base of the column on the foundation. When the height limit pole is hit, the corresponding part of the height limit pole will undergo a large plastic deformation under the impact load, which reduces the rigidity of the collision. Damage to the vehicle and its occupants. The plastically deformed parts of the height limiting rod are easy to replace, and other parts can be reused, safe to use and easy...

Abstract

The invention discloses an improved super-plasticity safety height limiting pole. The improved super-plasticity safety height limiting pole comprises two upright post foundation bases, two upright posts, two pull rods, one cross beam, one bumper beam and two pull rod foundation bases, wherein the upright post foundation bases and the pull rod foundation bases are fixed to the foundation; the first ends of the upright posts are rotatably connected to the upright post foundation bases, and the second ends of the upright posts are fixedly connected to the cross beam; the pull rods are made of super-plasticity materials, the first ends of the pull rods are rotatably connected to the second ends of the upright posts, and the second ends of the pull rods are rotatably connected to the pull rod foundation bases; the bumper beam is provided with a honeycomb structure and is connected to the cross beam, and the bumper beam faces an incoming vehicle after the bumper beam is installed in place. Through the transformation and energy absorption of the bumper beam and the super-plasticity pull rods, the impacted vehicle is effectively prevented from being damaged, and the driver and passengers of the vehicle are prevented from being injured; moreover, after the vehicle is impacted, only the pull rods and the bumper beam are changed, the changing operation is simple and convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of road safety facilities, in particular to an improved superplastic safety height-limiting pole. Background technique [0002] In road traffic, it is often necessary to limit the loading height of passing vehicles through height limiting devices. For example, highways, ramps, culverts, bridges, etc. need to limit the traffic height to ensure road traffic safety. With the continuous increase of the number of vehicles, pole collision accidents occur frequently, and the height limit pole breaks, the car is seriously damaged, and other vehicles and pedestrians are injured due to the breakage of the height limit pole, resulting in serious property and personnel losses. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved superplastic safety height-limiting pole in view of the serious property loss caused by the rigid collision between the ...
