Embodiment Construction

[0014] Spherical steel bearings can be functionally divided into ordinary spherical bearings and hyperboloid spherical vibration isolation bearings (or friction pendulum ball vibration isolation bearings). The support is divided into three types: one-way movable type, multi-directional movable type and fixed type. Pot-type rubber bearings, spherical bearings, hyperboloid spherical vibration isolation bearings (or friction pendulum ball vibration isolation bearings) and other types of bearings can all add the lever assembly of the present invention to change the lower seat The structure of the plate and the base plate realizes the vertical vibration isolation function.

[0015] A vertical vibration-isolating spherical steel bearing with a lever assembly, the lower seat plate 5 and the base plate 8 of the spherical steel bearing are arranged up and down, and the two sides of the base plate 8 are respectively provided with stoppers 8-1, two stoppers. The sides of the block 8-1 a...

Abstract

Disclosed is a vertical vibration isolation spherical steel support with lever assemblies. A lower support plate and a bottom support plate of the spherical steel support are arranged in the verticaldirection; retaining blocks are separately arranged on two sides of the bottom support plate; the side surfaces of the two retaining blocks are separately in contact with two sides of the lower support plate; the upper surface of a bottom plate of the bottom support plate is provided with lever fulcrum curved surfaces which are symmetric about an axis center line of the spherical steel support; the center of the bottom surface of the lower support plate is provided with two embedded curved surfaces which are symmetric about the axis center line of the spherical steel support; the two sets of lever assemblies are arranged in the space enclosed by the lower support plate and the bottom support plate; the two sets of lever assemblies are symmetrically arranged on two sides of the axis centerline of the spherical steel support; and each of the lever assemblies comprises a rotating block, a lever and an elastic body. By virtue of the lever principle, the levers and the elastic bodies, thevertical stiffness of the support is split into the compression stiffness of the elastic bodies through the levers so as to appropriately reduce the overall vertical stiffness of the support. The vertical fundamental frequency is far from the main frequency of the vibration of an upper structure of the support so as to realize the vertical vibration isolation function.

Description

technical field [0001] The invention relates to the technical field of bridge structures or buildings, in particular to a vertical vibration-isolating spherical steel bearing with a lever assembly. Background technique [0002] With the rapid development of rail transportation, a series of environmental problems such as noise and vibration generated by trains have arisen. Bridge vibration isolation bearing is a new type of bridge vibration isolation product. It is mainly used in areas along the bridge with strict requirements and restrictions on surrounding vibration and noise and urban viaducts. It mainly plays the role of vibration reduction, vibration isolation and noise reduction. . The existing bridge vibration isolation bearing products are mainly rubber vibration isolation, but there are certain defects in vertical bearing capacity, quality stability, vibration isolation performance and life. SUMMARY OF THE INVENTION [0003] In order to solve the above technical ...
