Rotary vibration isolator

Abstract

The invention relates to a rotating vibration-isolation bearing, which belongs to the field of vibration-isolation and shock absorption of building structures. It is mainly composed of a rotating body connected with the upper structure and a groove fixed on the foundation. The rotating body includes an upper anchor rod, an anchor plate, a steel column and a part of a spherical body with corners cut off. The upper surface of the anchor plate is connected The lower surface of the anchor plate is connected to the upper end of the steel column, and the lower end of the steel column is connected to the part of the spherical body with the corner cut off. The groove includes a steel spherical concave shell, the lower anchor rod, and the rotation limit block. and the rotation block, the outer part of the spherical concave shell is connected with the lower anchor rod, and the interior of the spherical concave shell is fixed with the rotation limit block and the rotation block, and the rotation block is closely attached to the cutting surface of the part of the spherical body, and the rotation Limiting blocks are fixed at the end positions of the spherical concave housing. The invention has a clear concept and clear force transmission, and is beneficial to popularization and application in vast earthquake fortification areas.

Description

technical field [0001] The invention relates to the field of shock isolation and shock absorption of building structures, in particular to a rotating shock isolation support. Background technique [0002] At present, the vibration isolation and shock absorption technology is developing rapidly. There are many types of vibration isolation bearings, mainly divided into rubber bearings and steel bearings, and steel bearings are further divided into flat bearings, arc bearings, roller bearings, etc. These Bearings have been used in various projects, among which rubber bearings and flat bearings can only move in a plane, and arc bearings and roller bearings have a certain rotational ability, but their rotational ability is relatively poor. [0003] Therefore, it is urgent and particularly meaningful to research and develop a shock-isolation bearing with strong rotation ability and certain self-resetting function. Contents of the invention [0004] In order to overcome the defi...
