Anti-pulling universal rolling supporting base

Abstract

The invention relates to an anti-pulling universal rolling supporting base and belongs to the field of shock-isolating and damping control of a building structure. The upper part of a supporting base is provided with a cover plate structure; a connecting plate on the upper part is connected to an upper base plate and the upper base plate is connected to an upright column part of a rolling plate, thus the cover plate structure is formed; the rolling plate is supported on a ball bearing; the ball bearing is arranged in a base slot at the bottom; a rolling space is supplied to the ball bearing by the base slot, so that the ball bearing can freely roll in the base slot at the bottom; a through cavity is formed between the upper base plate and the rolling plate; an upper plate of an anti-pulling cover plate can be inserted into the cavity when the upper plate horizontally moves; a lower plate of the anti-pulling cover plate is fixedly connected to the base slot; and the base slot is located in the cavity formed by the lower part of the anti-pulling cover plate. The anti-pulling universal rolling supporting base has the advantages of simple construction, clear and reasonable force transmission, novel materials, uniform size, high anisotropic stability, high applicability, convenience in manufacturing and mounting, and strong practicability.

Description

technical field [0001] The invention relates to an anti-pull universal rolling bearing, which belongs to the field of shock-isolation and shock-absorbing control of building structures. Background technique [0002] The rapid development of economy makes people's demand for large space increasing day by day, which undoubtedly promotes the development of space structure, and at the same time puts forward higher requirements for space structure. Long-span spatial structures have light weight, high flexibility, small damping, and low natural vibration frequency, and are more sensitive to earthquake loads. The use of seismic isolation bearings in long-span spatial structures is a more feasible seismic isolation measure. From the research and application of long-span structural bearings, laminated rubber materials and sliding steel ball hinge bearings are mostly used. Each of these structural forms has its own advantages and disadvantages. The main disadvantages of these structu...

Problems solved by technology

Because the ball is made of high-strength alloy steel, it has strong pressure bearing capacity, and the friction coefficient is only about 10% of the sliding friction coefficient. Therefore, the use of rolling shock isolation device can overcome the vertical load of the existing PTFE material Insufficient force or excessive support area
