Oscillating type anti-earthquake device independent of bearing

Abstract

The invention discloses an oscillating type anti-earthquake device independent of bearing. The oscillating type anti-earthquake device comprises a cover plate, an upper limiting plate, a lower limiting plate and a base plate from top to bottom. The bottom face of the cover plate is provided with spherical coronary hook faces. Universal spherical rolling wheels are mounted at the positions, corresponding to the spherical coronary hook faces, of the upper limiting plate. The bottom face of the upper limiting plate is provided with short pillars. The short pillars penetrate the lower limiting plate and are fixedly connected with the base plate to form a fixed assembly body. The upper surface of the lower limiting plate is provided with vertical baffles. The vertical baffles are fixedly connected with the cover plate to form a movable assembly body. When shock occurs, the fixed assembly body remains motionless relative to a bottom support face. The movable assembly body moves relative to the fixed assembly body. The universal spherical rolling wheels roll freely at original positions and return to original balance positions under the effect of the gravitational field. The oscillating type anti-earthquake device is simple in structure, convenient to use and reliable in effect; the dynamic characteristics of the device are related to the structural dimensions of the device; the anti-earthquake protection requirement under any bearing condition is met; vertical release is prevented while free translational motion in any direction in the plane is achieved; and the device is applicable to anti-earthquake protection of high-value articles.

Description

technical field [0001] The invention relates to the field of anti-shock / vibration protection for high-value items such as cultural relics collections, precision instruments, and important items, and in particular to a load-independent pendulum type anti-shock device, which is suitable for shock / vibration isolation under various loads. Background technique [0002] my country is located at the junction of two major geological tectonic plates, frequent earthquakes bring great harm, and people's lives and property safety are threatened. At present, my country's earthquake fortification design aims to minimize casualties caused by earthquakes. There are few considerations for the safety of items in buildings, and indoor items are seriously damaged during earthquakes. Safety and security is of great significance and is imminent. [0003] Museums are the carriers that bring cultural relics and other collections to life during protection and utilization. A large number of movable c...
