Abstract

The invention provides a spring damping vibration attenuation pipeline support with the adjustable prestress. The spring damping vibration attenuation pipeline support comprises two uprights and upright sleeves, wherein the upper ends of the uprights are sleeved with the upright sleeves. The upright sleeves are connected through a connecting beam. Vibration attenuation cavities are formed in the upright sleeves. Damping springs are arranged in the vibration attenuation cavities. The upper ends of the uprights pass through upright channels and buffering vibration attenuation is achieved through the damping springs in the vibration attenuation cavities. Pull rods are arranged between the uprights and the upright sleeves. The distances between the uprights and the upright sleeves are adjusted through nuts at the screw ends of the pull rods, so that the prestress applied by the pull rods is adjusted. Through the adoption of the spring damping vibration attenuation pipeline support, the springs and a common support are combined together to form the spring damping vibration attenuation pipeline support; the vertical vibration attenuation effect is achieved through the springs; the uprights and the sleeves provide horizontal resistance; the defect that a common vibration attenuator is small in horizontal resistance in the prior art is overcome; the effective length of the pull rods with screws arranged at the ends can be adjusted through the nuts; the prestress adjusting purpose is achieved; and the prestress adjusting function which cannot be achieved by the common vibration attenuator is added.

Description

technical field [0001] The invention relates to a vibration damping device, in particular to a prestressed adjustable spring damping vibration damping pipeline support mainly for damping vibration of large pipelines connected with equipment such as heat pump units and high-power water pumps. Background technique [0002] A complete set of large-scale equipment must cooperate with the pipeline for medium circulation to work normally. For example, when the air-cooled heat pump unit is working, it needs to input water of a certain temperature into each room through the pipeline to adjust the indoor temperature; the high-pressure water pump system needs to pass through the pipeline. Deliver high-pressure water to the design height. This type of equipment will generate strong vibration when it is working, and this vibration will also be transmitted to the pipes connected to it. If these pipes are supported on the floor, the vibration of the pipe will cause the vibration of the fl...
