Problems solved by technology

[0006] It can be seen that in practical applications, the friction of the chute mechanism often leads to an unconstrained state that is not completely ideal in the horizontal direction, which has a great impact on the horizontal shock absorption and isolation perfor

Abstract

The invention relates to an anti-pull compound friction pendulum seismic isolation support based on double connecting rods. The anti-pull compound friction pendulum seismic isolation support comprisesa support body and anti-pull mechanisms arranged on the two sides of the support body, and the support body comprises a lower support plate (2) fixedly connected with a base, an upper support plate (1) fixedly connected with an upper structure, and constant-radius bispherical sliding blocks (3) arranged between the upper support plate (1) and the lower support plate (2); and the anti-pull mechanisms comprise double-connecting-rod assemblies hinged to the upper support plate (1), and limiting assemblies arranged on the lower support plate (2), and the double-connecting-rod assemblies and the limiting assemblies are connected through spherical hinges. Compared with the prior art, the double connecting rods are creatively applied to the anti-pull mechanisms of the compound friction pendulumseismic isolation support, thus the problem that an upper structure of a common compound friction pendulum seismic isolation support possibly overturns is solved, meanwhile, it is also ensured that the original seismic isolation performance of the compound friction pendulum seismic isolation support is not affected, and the compound friction pendulum seismic isolation support has the good performance in structure seismic resisting.

Description

technical field [0001] The invention relates to a shock-isolation support, in particular to a double-link anti-pulling complex friction pendulum shock-isolation support. Background technique [0002] Seismic isolation bearings are shock-absorbing and isolating devices installed at the bottom of buildings, bridges, and large electrical equipment. They must not only bear the weight of the upper structure, but also reduce the input of earthquake vibrations and consume seismic energy under seismic loads. The friction pendulum shock-isolation bearing is a kind of bearing with high shock-absorbing and isolation effect. Its basic principle is: under the action of an earthquake, the upper and lower bearing plates of the bearing will slide relative to each other, and the convex spherical surface of the slider and the bearing plate will The sliding friction of the concave spherical surface consumes energy, reduces the input of earthquake vibration, and consumes earthquake energy.
