Abstract

The invention discloses a linkage device for bridges. The linkage device comprises rubber-coating cylinders and a connecting cylinder which are detachably connected in butt joint. The rubber-coating cylinders are filled with elastomer materials inside and provided with a connecting shaft axially arranged at the center, the end, extending out of the left end of the left rubber-coating cylinder, of the connecting shaft is connected with a knuckle bearing in a threaded manner, the knuckle bearing is rotatably connected to a connecting lug through a pin roll, the connecting shaft is fixedly connected at the right end of the connecting cylinder, the right end of the connecting shaft is connected with a knuckle bearing in a threaded manner, and the knuckle bearing is rotatably connected to a connecting lug through a pin roll. The linkage device for the bridges has the advantages that relative movement occurs between a cylinder wall of the rubber-coating cylinder and the connecting shaft under the action of axial stretching or contracting, so that the elastomer materials are subjected to shearing action, and kinetic energy is converted into internal energy of the elastomer materials to achieve the effect of buffering.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a linkage device for bridges. Background technique [0002] When the bridge is in use, the structure needs to be able to adapt to the deformation caused by thermal expansion and contraction of the material, and it is not expected that the structure will produce excessive movement due to vehicle impact, braking, and earthquakes. [0003] Therefore, devices such as viscous dampers and speed locks are installed on many bridges to control the movement of the bridge structure. This type of device has relatively high requirements on processing accuracy and materials, and is often expensive, and the production and processing cycle is relatively long; moreover, the liquid medium in it often leaks due to the problem of sealing technology. Contents of the invention [0004] The purpose of the present invention is to provide a linkage device for bridges with simple structure, reliable pe...
