A Friction Energy Dissipation Support Device for Tower Vibration Reduction

Abstract

The invention provides a frictional energy consumption support device for tower vibration reduction, which includes a support frame arranged outside the tower, a card slot is fixedly arranged on the support frame, and fixed connection is fixed on the two side walls of the card slot. For the friction plate, there are fixedly connected friction sliders, springs, connecting sliders and supporting connecting rods in order from far to near in the card slot. The two sides of the friction sliders are in contact with the fixed friction plates, and the connecting sliders The width of the block is smaller than that of the friction slider; the side end cover is provided at the port of the card slot near the side of the tower, the supporting connecting rod runs through the side end cover, the end of the supporting connecting rod is provided with a connecting ring, and the connecting ring is pierced with a tower connection Rod, the tower connecting rod is fixedly connected with the tower. The invention can ensure that the support has sufficient rigidity to meet the use requirements in light wind or weak earthquake, and protect the structure from being damaged in strong earthquake or strong wind in case of strong earthquake or strong wind, thereby broadening the application range of the frictional energy dissipation support.

Description

technical field [0001] The invention belongs to the technical field of tower vibration reduction for petrochemical industry, and more specifically relates to a friction energy consumption support device for tower vibration reduction. Background technique [0002] The tower is the equipment used in petrochemical production to complete rectification, extraction and absorption. The equipment used for rectification, extraction and absorption in petrochemical production. Due to its high height, tower equipment is often installed outdoors due to space constraints. Therefore, in addition to operating loads and gravity loads, tower equipment also bears wind loads and seismic loads under natural conditions. With the continuous development of the field of steel materials and higher requirements in technology, the design and manufacturing parameters (height, aspect ratio, etc.) Wind loads and seismic loads are more prone to vibration. [0003] Among the currently commonly used anti-...

Problems solved by technology

However, the frame tower still has the possibility of vibration, and once resonance occurs, due to the high critical wind speed, the wind load will increase accordingly, so that the vibration amplitude of the original frame tower may be greater than the resonance amplitude of a single tower

Although the installation of spoilers can destroy the generation of wake vortices, due to the existence of accessories such as platforms and ladders, the installation of spoilers such as axial fins or spiral fins is not suitable for all tower equipment
