Adjustable rope high-damping combined anti-falling beam device

Abstract

The invention discloses an adjustable rope high-damping combined anti-falling beam device, and relates to the technical field of a bridge secondary protection device. The adjustable rope high-dampingcombined anti-falling beam device comprises a tubular regulating end protection cover with an opening formed in one end, and a tubular fixed end protection cover with an opening formed in one end, wherein a regulating end anchor tool and a sticky fluid damping device are sequentially arranged in the regulating end protection cover in the axial direction from the inside to the outside; a regulatingend embedded pad plate is connected outside the opening end of the regulating end protection cover; the sticky fluid damping device is connected with the regulating end embedded pad plate through a support tube; a fixed end anchor tool is arranged in the fixed end protection cover in the axial direction; a fixed end embedded pad plate is connected outside the opening end of the fixed end protection cover; the regulating end embedded pad plate and the fixed end embedded pad plate are connected through an embedded pipe; a rope body is formed in the embedded pipe in the axial direction; one endof the cable body passes through the regulating end embedded pad plate, and enters the sticky fluid damping device; then, an outwards extending steel twisted tire is inserted into the regulating end anchor tool. Compared with the prior art, the adjustable rope high-damping combined anti-falling beam device has the advantages that the position limiting effect is good; the shock absorption effect isgood.

Description

technical field [0001] The invention relates to the technical field of bridge secondary protection devices, in particular to an adjustable cable high damping combined anti-drop beam device. Background technique [0002] my country is one of the countries with the strongest seismic activity and the most serious earthquake disasters in the world, and beam falling is one of the bridge earthquake disasters with the highest frequency, the most destructiveness and the most difficult repair in earthquakes. The anti-drop beam device is a protective system that prevents the upper structure of the bridge from falling off from the top of the lower structure due to unpredictable large displacements under the action of the earthquake. It is one of the important components of the beam bridge shock-absorbing components. In the working state or when there is a small earthquake, the anti-drop beam device does not play an obvious role, and the upper structure can freely expand and contract or...
