Supporting device for large-diameter pipeline

Abstract

The invention discloses a supporting device for a large-diameter pipeline. The supporting device comprises two sets of symmetrically-arranged supports; each support comprises a supporting stand column, an upper spherical sliding pair is installed at the upper end of the supporting stand column, and a lower spherical sliding pair symmetrical to the upper spherical sliding pair is installed at the lower end of the supporting stand column; a pipeline base is installed at the upper end of each supporting stand column through an upper connecting stud and nut set; the lower end of each supporting stand column is provided with a bottom support through a lower connecting stud and nut set; and each of the upper connecting stud and nut sets and the lower connecting stud and nut sets is provided with a disc spring set. The supporting device is used for supporting the large-size and large-temperature-difference pipeline, and has flexibility adapting to axial and transverse deformation of the pipeline while maintaining the supporting rigidity of the pipeline; compensation and rigidity control of the supports on radial and axial deformation of the pipeline on a supporting section are realized by the aid of the rotational degree of freedom of the spherical sliding pairs in space and the rigidity compensation effect of the disc spring sets.

Description

technical field [0001] The invention relates to the field of pipeline support, in particular to a support device for large-diameter pipelines. Background technique [0002] Many large-diameter pipelines are placed in the open air, and the pipelines are complex. Due to changes in ambient temperature, changes in pipeline medium loads, wind loads, and seismic loads, the pipelines will undergo radial and axial deformation and displacement, and difficult To control the vibration of the piping system, it is usually necessary to set up a suitable support structure to support the weight of the piping, control the deformation and displacement of the piping, suppress the vibration of the piping, and prevent the piping from being affected by excessive deformation, excessive stress, and excessive vibration. Normal work, especially to prevent pipeline damage and resulting safety accidents. The traditional pipeline hanger is a fully flexible structure, which can release pipeline deformat...

AI Technical Summary

Problems solved by technology

The traditional pipeline hanger is a fully flexible structure, which can release pipeline deformation, but its rigidity is insufficient, and it lacks the function of damping and stopping vibration. It is necessary to increase the overall rigidity of the pipeline through additional fixed support supports to limit the large displacement and vibration of the pipeline.

However, the shrinkage and warping deformation of the pipeline often lead to the detachment of the support bottom surface from the foundation, and the sliding surface is destroyed, so that the deformation of the pipeline cannot be effectively released
