Inner and outer double-tube self-supporting self-adaptive anti-vibration steel chimney

Abstract

The invention relates to an inner and outer barrel self-erected self-adaptive shake resistance steel chimney which comprises a self-erected inner barrel and a self-erected outer barrel sleeving the self-erected inner barrel. Multiple frequency modulation shake-preventing spring devices are installed at the cross section positions which are located between the self-erected inner barrel and the self-erected outer barrel and at different heights, and multiple frequency modulation shake-preventing spring devices are evenly distributed at the same cross section positions. The self-erected inner barrel and the self-erected outer barrel are integrally connected through the frequency modulation shake-preventing spring devices. When two barrels shake under the effect of external force, the barrels drive the frequency modulation shake-preventing spring devices to move. Due to the relative displacement between two points, the frequency modulation shake-preventing spring devices can perform reciprocating motions, produced inertia force is fed back and acts on the devices, energy can be directly reduced (shock reduction), isolated (shake isolation), transferred (shake absorption and reduction) and consumed (energy consumption and shock reduction), and the effect of structural shake can be inhibited. The purposes of stopping shake of the double-barrel self-erected steel chimney and prolonging the service life are achieved.

Description

technical field [0001] The invention relates to an inner and outer double-tube self-supporting self-adaptive anti-vibration steel chimney. Background technique [0002] At present, the anti-sloshing device of the inner and outer cylinders of the steel chimney is a rigid structure. When the vibration is caused by the wind, it is directly transmitted to the inner cylinder of the steel chimney through the anti-sloshing device. Wind vibrations have almost no effect. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and to provide a self-supporting self-adaptive anti-vibration steel chimney of inner and outer double cylinders. [0004] The object of the present invention is achieved through the following technical solutions: [0005] The inner and outer double-tube self-supporting self-supporting self-supporting anti-vibration steel chimney includes a self-supporting inner tube and a self-supporting outer ...
