[0006] A protective structure for highway engineering, comprising symmetrically distributed first angle steels, wherein the top inner wall of the first angle steels is slidably connected to columns distributed at equal distances, and the outer wall of the column is rotatably connected to a guide roller, the bottom outer wall of the column is hinged with a connecting seat, a second angle steel is arranged between two first angle steels on opposite sides, and a buffer plate is fixedly connected between the first angle steel and the second angle steel;
[0007] A first vertical plate and a second vertical plate are welded to the inner wall at the top of the first angle steel, and a deceleration plate is hingedly connected to the outer wall on one side of the first vertical plate, and symmetrically distributed springs are fixedly connected between the deceleration plate and the second vertical plate.
[0008] Preferably, an anti-slip tape is bonded to the outer wall of the buffer plate.
[0009] Preferably, a butt plate is fixedly connected between the two first angle steels on the same side.
[0010] Preferably, symmetrically distributed vertical frames are welded to the outer wall of the bottom of the second angle steel.
[0011] Preferably, the bottom and top of the outer wall of the column are fixedly connected to a bottom plate and a top plate respectively, and the guide roller is arranged between the bottom plate and the top plate.
[0012] Preferably, a fixing sleeve is fixedly connected to the top outer wall of the column, and the fixing sleeve is fixedly connected to the top inner wall of the first angle steel.
[0013] Preferably, the buffer plates are of a wavy curved structure, and the buffer plates are symmetrically distributed on both sides of the second angle steel.
[0014] The beneficial effects of the utility model are:
[0015] 1. This design is used for the protection structure of highway engineering. When a car collides with this structure, it will first contact the guide roller, which can provide initial buffering and be used to straighten the vehicle. At the same time, the buffer plate with a wavy curved structure can absorb kinetic energy and provide secondary buffering, thereby reducing the degree of damage to the vehicle and improving the safety of the people in the vehicle;
[0016] 2. The protective structure of the highway engineering designed in this invention can contact the speed brake at certain intervals while the vehicle slides along the guide roller. The spring connected between the speed brake and the second vertical plate can avoid hard contact between the vehicle and the speed brake. The speed brake is also provided with an anti-skid belt, which can increase the deceleration effect while reducing vehicle wear, prevent the vehicle from sliding for too long, and reduce the severity of traffic accidents as much as possible.
