A hydraulic damping device with sliding function in vertical axis

Abstract

The invention discloses a hydraulic damping device capable of sliding in the direction perpendicular to the axial direction. The hydraulic damping device comprises an upper anchorage plate assembly, a sliding plate assembly, connecting plates, viscous damper bodies, length adjusting blocks, corner assembly blocks, base assemblies and lower anchorage plate assemblies. The upper anchorage plate assembly and the sliding plate assembly are mutually and fixedly connected. The sliding plate assembly and each connecting plate are in contact with each other to form a friction surface. Each connecting plate and the corresponding viscous damper body are fixedly connected with each other. Each viscous damper body is inserted into the corresponding length adjusting block. Each length adjusting block is connected with the corresponding corner assembly block in a threaded mode in parallel. Each corner assembly block and the corresponding base assembly are fixedly connected with each other. Each base assembly and the corresponding lower anchorage plate assembly are fixedly connected with each other. Axial action force is transmitted to the viscous damper bodies through horizontal contact between the sliding plate assembly and the connecting plates, and sliding in the direction perpendicular to the axial direction is achieved through the friction contact surfaces of the sliding plate assembly and the connecting plates.

However, the general liquid viscous damping device can only be installed in its axial force system alone in use. For special bridge construction, the liquid viscous damping device needs to be slidable in the vertical axis, and there is a lack of corresponding products. structural design

[0003] At present, in solving the problem of being able to damp in the axial direction and slide in the vertical axis, it is generally considered to use a multi-directional shock-absorbing and isolating support, and the damper is arranged in the multi-directional shock-isolating support, and its structure is complicated. , not only to bear vertical load, but also to bear horizontal force and large reciprocating displacement, the force transmission is unstable, and the cost is high, especially for bridge buildings with limited installation space.
