Embodiment Construction

[0019] refer to figure 1 , a multi-cylinder combined viscous damper, which includes a combined cylinder 10, the combined cylinder 10 is formed by at least two master cylinders that are detachably and sequentially sealed together along an axis 200 , the at least two master cylinders are arranged coaxially, and the master cylinders located at both ends are the first master cylinder and the end master cylinder respectively.

[0020] In this embodiment, the combined cylinder 10 includes two main cylinders, namely the first main cylinder 11 and the second main cylinder 31, both of which are cylindrical and have the same shape as the axis 200. Overlapping central axis. The two main cylinders are connected together via a connecting column 51, both ends of the connecting column 51 are formed with external threads, and one end of the two main cylinders is formed with internal threads, so that the two main cylinders are connected by threads way to connect. A central guide rod hole 51...

Abstract

The invention discloses a multi-cylinder combination type viscous damper which comprises a combined cylinder tube. The combined cylinder tube comprises at least two main cylinder tubes connected witheach other, the at least two main cylinder tubes are coaxially arranged, and the main cylinder tubes positioned at the two ends are separately a first section main cylinder tube and an end section main cylinder tube; a guide rod is arranged axially, the guide rod, from the end section main cylinder tube, sequentially penetrates through the various main cylinder tubes and extends out of the first section main cylinder; a piston fixedly connected to the guide rod is arranged in each of at least two main cylinder tubes, and under the driving of the guide rod, the pistons are capable of axially moving in the main cylinder tubes in which the pistons are; damping channels penetrating through the two ends of the piston are formed in the pistons; a first sealing part is installed at the end, far away the end section main cylinder tube, of the first section main cylinder tube, and a second sealing part is installed at the end, far away the first section main cylinder tube, of the end section main cylinder tube; and damping medium is filled in the combined cylinder tube. The multi-cylinder combination type damper has a long and narrow appearance, can be installed in long and narrow space, and provides buildings with safety security.

Description

technical field [0001] The invention relates to the field of anti-seismic fortification of buildings and bridges, in particular to a multi-cylinder combined viscous damper. Background technique [0002] As an effective energy-dissipating vibration-reducing device, viscous dampers are widely used in anti-seismic fortification fields such as buildings and bridges. [0003] Traditional viscous dampers only have one main cylinder and one piston. The greater the required damping force, the larger the diameter of the main cylinder of the viscous damper. However, in some special projects, the required damping force is very large, but the installation space provided for the damper is narrow and long, which cannot meet the installation conditions of the existing damper, and affects the safe use of the building. Contents of the invention [0004] The purpose of the present invention is to overcome the phenomenon that the damper cannot meet the narrow and long installation space in ...
