Emergency anti-collision bridge capable of rapidly building simple bridge through railings

Abstract

The invention discloses an emergency anti-collision bridge capable of rapidly building a simple bridge through railings. The emergency anti-collision bridge comprises a bridge body, protection rods, protective plates, lower breast boards and connecting rods. Limiting grooves are formed in the bridge body; stand column rods are connected into the limiting grooves in a clamping manner; rubber pads are connected into the limiting grooves through screws; two-way threaded rods are installed on the fixed base and rotationally connected to the bridge body; gear tooth rods are connected to the stand column rods in a clamped mode; the protection rods are connected to the top ends of the gear tooth rods through screws; circular gears are connected to the gear tooth rods in an engaged mode; and the circular gears are welded and fixed to the fixed shaft. According to the emergency anti-collision bridge capable of rapidly building the simple bridge through the railings, through the protection plates, when an automobile collides with the stand column rods on the bridge body, the protection plates can stably press down and limit the automobile, then the automobile can be effectively prevented from overturning after collision, and the use safety of the bridge is improved.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an emergency anti-collision bridge that can quickly build a simple bridge with railings. Background technique [0002] A bridge is an integral part of a road, which refers to a building built for the road to cross natural or artificial obstacles, so that vehicles and pedestrians can pass smoothly, and most of the natural obstacles in towns are rivers. Therefore, in towns Most of the small stone arch bridges have been built. Because stone arch bridges use natural stone as the main building material, they are relatively simple in structure, easy to build, and have a long service life, so they are quite popular. [0003] However, most bridges now have the following problems: [0004] 1. When a car is driving on a conventional bridge and collides with the railing of the bridge in an accident, the railing cannot effectively protect the car and limit the position. secondary injury; ...

AI Technical Summary

Problems solved by technology

[0008] The object of the present invention is to provide an emergency anti-collision bridge that can quickly build a simple bridge with railings, so as to solve the problem of the railings of bridges on the market currently proposed by the above-mentioned background technology. It is impossible to effectively protect and limit the car, and it is inconvenient to carry out temporary construction work, and it is inconvenient to disassemble and replace the railings
