Non-destructive vibration reduction device and its construction technology for existing steel structure supporting precision equipment

Abstract

The invention discloses a nondestructive damping device used for existing steel structure support precision equipment. A steel structure support comprises a base bedplate, a support frame main beam, support frame secondary beams and support frame columns. The nondestructive damping device comprises air spring shock absorbers and an over beam, the two ends of the over beam are connected with the support frame columns respectively, the lower bottom plates of the air spring shock absorbers are supported on the over beam, and the upper bottom plates of the air spring shock absorbers penetrate through the gaps formed between the support frame main beam and the support frame secondary beams and are connected with the base bedplate. According to the nondestructive damping device and the construction technology, the structure is changed little, the wastage, caused by large-area construction, of inherent structures and the upper precision equipment is avoided, non-stop nondestructive damping of the precision equipment is achieved, the problems that current vibration control equipment needs to be stopped for removing devices and accordingly the structures are damaged when the vibration control equipment is installed, replaced and maintained are effectively solved, and the construction method is simple, environmentally friendly and free of pollution.

Description

technical field [0001] The invention relates to the technical field of vibration control of precision equipment supported by steel structures, in particular to a non-destructive vibration damping device used for precision equipment supported by steel structures and a construction process thereof. Background technique [0002] At present, there is basically no non-stop non-destructive vibration reduction technology for precision equipment in actual engineering. Similar vibration reduction technologies are all carried out in the shutdown state, that is, after the equipment is shut down, the original site structural components are removed and replaced with new components or new vibration reduction devices are installed. In summary, these similar damping methods have the following drawbacks: [0003] (1) Damage to the inherent structure. In actual engineering, the structure needs to be constructed after the equipment is shut down. The demolition of the original structural comp...

AI Technical Summary

Problems solved by technology

In actual engineering, the structure needs to be constructed after the equipment is shut down. The demolition of the original structural components will cause a certain degree of damage to the structure itself. New components or installation of vibration damping devices at the position of the demolished components may disturb the main structure and affect the structure. Natural frequency

[0004] (2) Precision equipment is damaged

The vibration generated in the process of dismantling the original structural components, building new structural components and installing vibration damping devices will cause a certain degree of damage to precision equipment

[0005] (3) Environmental pollution

During this period of time, due to the failure of the equipment to carry out normal production, certain economic losses will be caused
