Damping device

Abstract

The invention discloses a damping device. An elastic telescopic component can stretch out and draw back in the vertical direction; a transverse moving assembly is located at the top and / or the bottom of the elastic telescopic component and can move in the transverse direction relative to the elastic telescopic component; a nut and an inner barrel of a ball screw pair are both located in an outer barrel; a lead screw of the ball screw pair is sleeved with a mass block; the mass block is fixedly connected with the outer barrel; the nut of the ball screw pair is rotationally installed in the mass block and fixedly connected with the inner barrel; and a viscous medium is arranged between the inner barrel and the outer barrel. When the device is subjected to the transverse force action, the lead screw and the nut move relatively in the transverse direction, the nut drives the inner barrel to rotate, the viscous medium is sheared, and the elastic telescopic component can be prevented from being affected by the transverse acting force through the transverse moving assembly. When the device is subjected to the vertical force action, the elastic telescopic component can achieve the buffering function, and the transverse and vertical vibration isolation / shock effects are improved.

Description

technical field [0001] The invention is used in the technical field of building components, and in particular relates to a damping device. Background technique [0002] In terms of structure, the vibration isolation / seismic support is equivalent to the combination of vertical vibration isolation elements and horizontal vibration absorption elements, and is widely used in vibration isolation and isolation of building structures along subways, viaducts, etc. The vibration isolation / seismic support provides vibration isolation effect through vertical vibration isolation elements, and the shock absorption effect of structural earthquake vibration is provided by shock absorption elements, so as to alleviate the impact of external loads, reduce structural vibration, and protect structural safety. However, in practical applications, both the vertical vibration isolation element and the horizontal vibration absorption element of the vibration isolation / seismic support bear the verti...

Problems solved by technology

However, in practical applications, both the vertical vibration isolation element and the horizontal vibration absorption element of the vibration isolation / seismic support bear the vertical vibration and the ground vibration at the same time, causing a single element to play multiple roles. The force analysis of each element and the overall structure The design becomes complex, difficult, and poor in controllability, which also limits the application of vibration isolation / seismic bearings in nuclear power steam turbines, high-rise buildings, etc.
