Damping steel structure

Abstract

The utility model discloses a damping steel structure. The shock absorption steel structure comprises an outer cylinder, a transmission rod and a buffer cylinder are arranged above the outer cylinder, a buffer spring is arranged outside the transmission rod, four dampers are arranged outside the outer cylinder, and the outer cylinder, the transmission rod, the buffer cylinder and the buffer spring are matched with one another, so that the shock absorption steel structure is formed. The elastic force of the spring is reduced after the spring is subjected to long-time pressure from the upper portion, and after the pressure from the upper portion is buffered, high air pressure exists below the outer barrel, meanwhile, high air pressure also exists in the space between the transmission rod and the buffering barrel, and therefore the damping effect can be improved while partial impact is shared for the damper and a conventional buffering spring. The air pressure can jack up the transmission rod and the buffer cylinder, so that the structure can be assisted to make up the elastic force of the spring, and the problem that the rebound resilience of the whole mechanism is reduced due to the reduction of the elastic force of the spring is solved.

Figures 1-5 After being subjected to pressure from above for a long time, the spring elasticity decreases, and when the pressure from above is buffered, there is strong air pressure below the outer cylinder 1 and in the space between the transmission rod 2 and the buffer cylinder 3, which can lift the transmission rod 2 and the buffer cylinder 3, thereby assisting the overall structure to compensate for the spring elasticity and solving the problem of decreased resilience of the overall mechanism caused by the decrease in spring elasticity.
