Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring support technology, and in particular to an air-damped variable spring support. Background Technology
[0002] Currently, variable springs are widely used in pipeline installation in industries such as power and chemical engineering to bear loads and reduce vibration. However, during pipeline operation, the vibration reduction effect of variable spring supports is not obvious. When the pipeline is subjected to accidental loads or the pipeline system vibrates, vibration often occurs, causing the load on the pipeline supports to deviate from the design value. Some spring supports are subjected to excessive force, resulting in spring compression and unload. Over a long period of pipeline operation, this will increase the stress of the entire pipeline system, posing a hidden danger to the safe and stable operation of the pipeline.
[0003] Publication number CN209540214U discloses an air-damped variable spring hanger, belonging to the technical field of spring hangers. Its features include: a housing, a tie rod, and a hanger assembly; a spring, a pressure plate, and an air cylinder are disposed within the housing; a piston rod is connected to the lower surface of the pressure plate; a through hole is provided on the top wall of the air cylinder; the lower end of the piston rod passes through the through hole and is connected to a piston; the piston is disposed within the air cylinder; damping holes are provided on the top and side walls of the air cylinder; an upper one-way valve is provided on the top wall of the air cylinder; a lower one-way valve is provided on the bottom plate of the housing; tie rod holes are provided on both the pressure plate and the bottom plate of the housing; the upper end of the tie rod is fixedly connected to the pressure plate; and the lower end of the tie rod is connected to the hanger assembly. This design overcomes the problem of poor vibration damping effect of variable springs during pipeline vibration, significantly reducing vibration factors such as accidental loads or airflow impacts during pipeline operation, making pipeline operation safer and more reliable. Furthermore, it is simple in design, easy to install and maintain, has low manufacturing costs, and is suitable for widespread application.
[0004] Although the above solution overcomes the problem of poor vibration reduction effect of variable springs when pipelines vibrate, the assembly of the hanger on the spring component requires multiple bolt fixation points, which is quite troublesome, and the damping adjustment component is inconvenient to operate due to the restriction of the spring. Therefore, we propose an air damping variable spring hanger. Utility Model Content

The transverse screw is assembled on the support bar plate through the threaded hole and is located above the pressure plate. The support disc is fixedly set at the bottom of the two support bars plate and is located below the bearing cylinder.
[0008] The adjustment assembly includes an upper exhaust vertical pipe, an upper regulating valve, a lower exhaust vertical pipe, and a lower regulating valve. The upper exhaust vertical pipe is fixedly installed on the top surface of the air cylinder and movably passes through the pressure plate.

The lower exhaust vertical pipe is fixedly installed on the bottom surface of the air cylinder and extends to the bottom of the bearing cylinder.

[0015] Beneficial effects:
[0016] 1. In this utility model, by setting a positioning component, two support plates on the top surface of the support disc can be inserted into the bearing cylinder and move through the pressure plate above the air cylinder. The threaded holes on the top side of the support plates then reach the top of the pressure plate. At the arc-shaped notch on the outer circumference of the top of the bearing cylinder, the transverse screw can be rotated and assembled onto the threaded holes on the top side of the two support plates. The support disc is then assembled onto the pressure plate through the support plates and the transverse screw.

By adjusting the exhaust speed, the damping force of the damping component can be adjusted. The equipment is simple and convenient to operate the damping adjustment component externally.
