Problems solved by technology

In the application of many seismic isolation projects, especially for long-span long-span bridges, it has been difficult to find a suitable product, that is, the bearing temperature displacement and seismic isolation functions of long-span bridges are not good Unified contradictions have never been well resolved
At the same time, the existing mechanism generally has the problem of large volume, which puts forward higher requirements for space and installation
Therefore, it is urgent to develop a product that can not only adapt to temperature displacement, but also can instantly activate the shock absorption and isolation function when an earthquake comes, no matter where the support is after temperature displacement, and solve the problem of its bulky size

Abstract

The invention relates to an equal rigid arm speed locking seismic isolation bearing which perfectly unifies the temperature displacement and seismic isolation function and also achieves the miniaturization requirement on the premise of guaranteeing the isolation effect. The technical scheme adopted by the equal rigid arm speed locking seismic isolation bearing includes a top seat board, an equal rigid arm, a shock transmission unit and a connecting seat. The top seat board is arranged at a steel basin. A sliding plate and a longitudinal guide are placed between the top seat board and the bottom seat plate. A ball concave plate welding is arranged at the bottom seat plate. The connecting seat is arranged at the right angle inside of the top seat board. The shell of the shock transmission unit is arranged at the top seat board. The end of a piston rod extending at both ends of the shell of the shock transmission unit is provided with a connecting block which is provided with a trapezoid tooth. The trapezoid tooth arranged at the connecting block mutually occludes the trapezoid tooth arranged at the connecting seat. One end of the equal rigid arm is connected to the bottom seat boar in hinge mode, while the other end is connected to the shell of the shock transmission unit in hinge mode. At least a pair of connecting seats symmetrically is arranged at the bottom surface of a top baseplate and at least a shock transmission unit is arranged at one side of the top seat board.

Description

technical field [0001] The invention relates to the technical field of supporting devices for bridges and other construction projects, and relates to a constant-rigid-arm speed-locked shock-absorbing and isolating bearing. Background technique [0002] The support is one of the important components in bridges and construction projects. Its function is to transfer the upper load of the bridge and building structure to the pier through the support, and at the same time ensure the required force, displacement and rotation of the structure. [0003] Since the Wenchuan earthquake in 2008, shock-absorbing and isolating bearings have been widely used and practiced like mushrooms after rain. The existing shock absorbing and isolating devices are mainly divided into rubber shock-isolation type, displacement-related type and speed-related type according to the working principle. The rubber shock-isolation type can act at the same time at the moment of the earthquake. Under normal con...
