An anti-collision device for a bridge pier capable of unloading forces

Abstract

The invention relates to the field of bridge equipment, in particular to an anti-collision device with a force discharging function for a bridge pier. The anti-collision device comprises an anti-collision device body, a hauling device and a limiting device. The anti-collision device body comprises multiple anti-collision mechanisms. The hauling device comprises a suspending mechanism and multipleconnecting assemblies. The limiting device comprises a horizontal circular ring fixed to the pier and a limiting assembly in vertical sliding fit with the horizontal circular ring. Each anti-collisionmechanism comprises a circular force discharging assembly and buffer assemblies, wherein the buffer assemblies are arranged on the inner side of the circular force discharging assembly. The anti-collision device has the advantages that omni-bearing anti-collision operation can be carried out on the pier, the impact direction of a vehicle can be changed, thus, the vehicle is staggered from the pier, all impact force is eliminated, large losses are reduced, and the accident death rate is reduced.

technical field [0001] The invention relates to the field of bridge equipment, in particular to an anti-collision device for a bridge pier capable of unloading force. Background technique [0002] The current situation of traffic safety in our country is worrisome. Due to the increase in traffic volume, the contradiction between cars and bridges is becoming more and more prominent. Therefore, it is particularly necessary to take anti-collision measures for bridges. When the structure is damaged, the car should be protected as much as possible to minimize the loss. The existing anti-collision equipment for bridge piers in the field of bridge engineering can provide comprehensive anti-collision protection for bridge piers, but they all use buffer springs, which have a small buffering effect. , when encountering a collision, the effect is small, and there is no effect of unloading force, which cannot reduce much loss.

[0002] The current situation of traffic safety in our country is worrisome. Due to the increase in traffic volume, the contradiction between cars and bridges is becoming more and more prominent. Therefore, it is particularly necessary to take anti-collision measures for bridges. When the structure is damaged, the car should be protected as much as possible to minimize the loss. The existing anti-collision equipment for bridge piers in the field of bridge engineering can provide comprehensive anti-collision protection for bridge piers, but they all use buffer springs, which have a small buffering effect. , when encountering a collision, the effect is small, and there is no effect of unloading force, which does not reduce the loss much

[0003] In order to solve the above problems, a flexible energy dissipation bridge pier anti-collision device with the patent number CN201520625021.2 is disclosed, which includes a sandwich panel structure anti-collision wall set on the bridge pier, and the sandwich panel structure anti-collision wall includes multiple Layers of nested cylindrical steel plate layers, each steel plate layer is filled with elastic energy-dissipating material layers, the bottom of each steel plate layer is welded to the base steel plate, and the base steel plate is fixed on the bottom surface of the foundation through anchors. The sandwich panel structure Both the inner and outer sides of the anti-collision wall are covered with waterproof cloth, and the sandwich panel structure is used. On the basis of ensuring the strength, the mass is greatly reduced, and the bending strength is greatly improved. In the event of a collision accident, the rigid collision is converted into elastic-plastic Collision consumes a lot of energy and reduces the peak value of the collision stress. However, after consuming a large amount of impact force, the remaining impact force is still relatively large. The impact force cannot be removed, and the loss cannot be reduced much.
