A load-independent pendulum anti-vibration device

Abstract

A load-independent pendulum type anti-shock device, comprising a cover plate, an upper limit plate, a lower limit plate and a bottom plate from top to bottom; the bottom surface of the cover plate is provided with a spherical crown surface; Roller; the bottom surface of the upper limit plate is provided with a short column, and the short column passes through the lower limit plate and is fixedly connected with the bottom plate to form a fixed assembly; the upper surface of the lower limit plate is provided with a vertical baffle plate, and the vertical baffle plate is fixedly connected with the cover plate to form a mobile assembly ; When subjected to vibration, the fixed assembly remains stationary relative to the bottom support surface, the mobile assembly is displaced relative to the fixed assembly, and the universal spherical roller rolls freely in the original position and returns to the original equilibrium position by the action of the gravity field. The invention is simple in structure, easy to use, and reliable in effect. The dynamic characteristics of the device are only related to the structural size of the device itself, which meets the shockproof protection requirements under any load-bearing conditions, and realizes free translation in any direction in the plane while preventing vertical separation. It is suitable for Shock protection for high value items.

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...
