Abstract

The invention relates to the technical field of bridge pier collision avoidance, and especially relates to a gravity type self-resetting pier anti-collision device structure. The anti-collision devicestructure comprises a bearing platform arranged outside a pier in a sleeving mode, a main body steel shell arranged on the edge of the top of the bearing platform, an anti-collision steel block, a supporting steel column and a weight block, the outer side wall and the upper surface of the main body steel shell are provided with a groove used for allowing the anti-collision steel block to be inserted in and an opening used for allowing the supporting steel column to be inserted in respectively, and the opening communicates with the groove; the top of the inner end of the anti-collision steel block is provided with a slope inclining downwards; the top of the supporting steel column is connected with the bottom of the weight block, and the bottom of the supporting steel column is provided with a first pulley which slides in cooperation with the slope; and at least one extension spring is arranged between the weight block and the upper surface of the main body steel shell. The device structure has the advantages of being low in material price, simple in structure, convenient to construct, suitable for old bridges and new bridges, capable of being repeatedly used, easy to detect and maintain, convenient to disassemble and the like.

Description

technical field [0001] The invention relates to the technical field of bridge pier anti-collision technology, in particular to a gravity type self-resetting bridge pier anti-collision device structure. Background technique [0002] In recent years, with the improvement of my country's comprehensive national strength, my country's national economy is also growing rapidly, and transportation is an important supporting part of the national economy. Air transport, land transport, and water transport account for the main part of land transport and water transport, and both are closely related to bridges. Inseparable, oceans and inland rivers provide ships with water transport routes, but they are natural obstacles to land traffic. To save costs, you have to cross them, which promotes the construction and development of bridges; bridges are used as pedestrians and vehicles across the water. The channel is an artificial obstacle for ship navigation. [0003] At present, our country ...
