Description

Technical Field

[0001] The present application relates to the technical field of pipeline load-bearing equipment, and in particular to a vibration-isolating pipeline load-bearing hanger. Background Art

[0002] Seismic isolation technology is to set up seismic isolation devices at the base or a certain position of the building to form a seismic isolation layer, isolating the upper structure from the lower foundation, so as to consume seismic energy, avoid or reduce the transmission of seismic energy to the upper part, and more effectively ensure the safety of the upper structure, internal personnel and equipment. The electromechanical seismic isolation flexible connecting pipe is the connecting pipe between two sections of hard pipes in the building seismic isolation layer. The new regulations have improved the seismic isolation requirements, but there is not much description of flexible connections. Therefore, research on flexible connections is carried out to enhance their seismic isolation capabilities to adapt to the new regulations.

[0003] The existing reinforcement measures are to reinforce the outside of the double-fork connecting rod, which cannot adjust the slope of the pipeline, which may easily cause poor drainage and water discharge. Property personnel need to frequently enter and exit the seismic isolation layer for maintenance, increasing the safety risk and maintenance costs of limited spaces; and in minor earthquakes, it will limit the shaking of the flexible connection during earthquakes, and cannot effectively consume earthquake energy. In large earthquakes, the deadweight of the device may be applied to the pipeline during shaking, which may easily cause the pipeline to be damaged or the joints to slip due to excessive force, resulting in interruption of supply and leakage of the conveying medium, causing subsequent quality and safety accidents and repair costs, and reducing the reliability of seismic isolation.
