Problems solved by technology

Conventional dampers are clearly not up to the task
[0003] Therefore, there is a temporary lack of a product on the market that can provide a damping effect above a specific external force threshold, and only provide a rigid support effect below the threshold to meet market needs.

Abstract

The invention relates to the technical field of bridge earthquake resistance. The invention relates to a damper, in particular to a damper with limiting and shearing functions. The damper comprises adamper body, the damper body comprises a cylinder body, a first pin shaft hole is formed in one end of the cylinder body, a first pin shaft is arranged in the hole, a piston rod penetrates out of theother end of the cylinder body and then is connected with a second pin shaft base, a second pin shaft hole is formed in the piston rod, a second pin shaft is arranged in the hole, and a third pin shaft hole facilitating pin shaft insertion is formed in the cylinder body; the other end of the piston rod is located in the cylinder body and provided with a piston, the piston is provided with a fourthpin shaft hole facilitating insertion of the pin shaft, a third pin shaft is arranged in the third pin shaft hole, one end of the third pin shaft is located in the third pin shaft hole, and the otherend of the third pin shaft is located in the fourth pin shaft hole. And the third pin shaft is a shear pin. The rigid supporting effect can be achieved on the low-speed occasion, the damping effect is achieved when the high-speed or external force impact effect is large, and the stability and the firmness of a building structure in daily use can be effectively kept.

Description

technical field [0001] The invention relates to the technical field of anti-seismic bridges, in particular to a damper with a limit shearing function. Background technique [0002] A damper is a device that consumes motion energy by providing resistance. It is widely used in aerospace, aviation, military, guns, automobiles and other industries. With the development of science and technology, the application of dampers has gradually changed from aerospace and military to It began to be popularized for civilian use. At present, various types of dampers or damping devices made of dampers can be used in construction fields and traffic facilities such as bridges to reduce the impact of external forces acting on buildings or bridges. The general industrial damper structure often adopts a hydraulic form. The cylinder cavity is filled with hydraulic oil, and a piston and a piston rod are arranged in it. The piston rod passes through the cylinder and connects the stressed structure....
