Slidable transverse bridge direction compression self-resetting damper

Abstract

The invention discloses a slidable transverse bridge direction compression self-resetting damper which comprises a stress piece, a piston rod, spring assemblies, a left end cover, a cylinder body, a piston, a right end cover and a one-way valve. The left end cover and the right end cover block the left end and the right end of the cylinder body correspondingly, so that the left end cover, the right end cover and the cylinder body define closed space used for containing a damping medium. The piston is arranged in the cylinder body in a sealing and sliding manner and divides the closed space into a left chamber and a right chamber. The piston is provided with a damping hole used for communicating the left chamber with the right chamber and the one-way valve. The damping medium can flow from the left chamber to the right chamber through the one-way valve. The piston rod is arranged on the left end cover and the right end cover in the axis direction of the cylinder body in a sealed and sliding manner. The middle of the piston rod is connected with the piston so as to achieve synchronous movement of the piston and the piston rod. The left end of the piston rod is connected with the stress piece. The multiple spring assemblies are evenly distributed between the stress piece and the cylinder body in the circumferential direction. The slidable transverse bridge direction compression self-resetting damper achieves one-way damping and can also achieve self resetting.

Description

technical field [0001] The invention belongs to the technical field of one-way dampers, and more specifically relates to a self-resetting damper under pressure in the direction of a slidable cross bridge. Background technique [0002] Most of the existing dampers are two-way dampers, but the two-way dampers have certain disadvantages. When one end of the two-way damper is connected to a component that can only bear one-way pressure load, the two-way damper at this time will no longer be applicable. In such a scenario, otherwise, the structure will be easily damaged when the component is subjected to tensile load, or in order to prevent the structure from being damaged, it is necessary to increase the structural strength design of the non-acting force direction (unnecessary) in the original structure, which will increase the design cost . [0003] Especially in the field of bridges, such as the truss girder suspension bridge under the long-span full floating support system, ...
