Efficient shock absorber used for improving anti-collision function of bridge

Abstract

The invention provides an efficient shock absorber used for improving the anti-collision function of a bridge. The efficient shock absorber comprises a machine body, transverse rods are fixedly installed on the left side and the right side of the machine body, nuts are movably installed on the right sides of the transverse rods, threaded holes are formed in the bottoms of the nuts, fixed blocks are fixedly installed at the tops of the transverse rods, a metal cavity is fixedly formed in the top of an inner cavity of the machine body, and a compression cavity is fixedly formed in the top of themetal cavity. According to the efficient shock absorber used for improving the anti-collision function of the bridge, telescopic frames and the metal cavity are arranged, by means of extrusion springs on the outer surfaces of the telescopic frames and steel pipes entering the metal cavity, when the bridge is collided, impact force generated by collision is transmitted to the tops of the telescopic frames, impacting of impact force to the bridge and the shock absorber is reduced through collision friction force between a compression support, the extrusion springs and the steel pipes in the metal cavity, and the service life of the bridge and the shock absorber is prolonged through combination of multiple buffering manners.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a high-efficiency shock absorber for improving the anti-collision function of bridges. Background technique [0002] With the rapid development of the country, in order to increase the speed of travel between cities, the road and bridge construction department vigorously surveyed and built a large number of large-scale road facilities such as expressways and overpasses. Among them, in areas with many rivers such as Jiangnan, various bridges have been built The construction not only facilitates the passage of vehicles, but also saves the time for vehicles to travel. [0003] However, due to the rapid development of society, every household basically has all kinds of means of transportation, so that during rush hours, holidays, etc., the traffic volume on roads and bridges increases greatly, and many people are eager to move forward, jumping in line at random, etc. Various...

[0003] However, due to the rapid development of society, every household basically has all kinds of means of transportation, so that during rush hours, holidays, etc., the traffic volume on roads and bridges increases greatly, and many people are eager to move forward, jumping in line at random, etc. Various traffic accidents often occur on bridges in various places, so that the bridge body is damaged. In severe cases, the bridge may collapse, causing greater loss of life and property
