Vibration reducing support for pipeline hoisting

Abstract

The invention provides a vibration reducing support for pipeline hoisting. The vibration reducing support comprises a clamp and a connecting assembly, wherein two connecting arms in the connecting assembly are connected through a gas damper, and one of the connecting arms is hinged to the clamp; a rubber pressurizing gas bag is located between the two connecting arms, one-way valves are arranged at the two ends of the rubber pressurizing gas bag correspondingly, and one of the one-way valves communicates with a rodless cavity of the gas damper through a gas pipe; and a base is hinged to the other connecting arm through a hinge pin, a baffle is movably arranged on the hinge pin, a torsional spring is arranged on the hinge pin in a sleeving mode, and the two ends of the torsional spring extend into the base and the hinge pin correspondingly. The clamp is hinged to one connecting arm so that the clamp can swing at a small angle, and the two connecting arms squeeze the gas damper in the swinging process to achieve the vibration reducing effect; and the rubber pressurizing gas bag is squeezed by the two connecting arms, and then positive gas pressure is introduced into the gas damper, so that the vibration reducing damping size is adjusted, and excessive pipeline shaking amplitude caused by damping fixation during use is avoided.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a pipeline hoisting shock absorbing bracket. Background technique [0002] Publication No. CN109944983A provides a frictional energy-dissipating damping piping system. This device realizes the hoisting of the pipeline through the hinged connection between the anti-seismic bracket and the pipe clamp, and can swing along the anti-seismic bracket when facing the vibration of the pipeline. The anti-seismic bracket Only as a connecting component, there is no way to overcome the damping that weakens the swing, and the pipes are connected by flanges or other connecting components. If the pipe is in continuous swing, it will have a rigid impact on the connecting parts, and the movement equivalent of the pipe itself is limited. Not restricting the swing of the pipe itself will also have an impact on the overall structure. Contents of the invention [0003] The object of ...
