Anti-clamping-stagnation balancing device for expansion joint

Abstract

The invention relates to the technical field of expansion joint auxiliary devices, in particular to an anti-clamping-stagnation balancing device for the expansion joint. The anti-clamping-stagnation balancing device for the expansion joint comprises a first balancing device and a second balancing device which are completely the same in structure and shape. The first balancing device comprises a left mounting base, a left connecting rod, a supporting rod, a supporting base, a right mounting base, a right connecting rod, a locking pin and an auxiliary locking pin. The right mounting base and theleft mounting base are the same in shape, and the right connecting rod and the left connecting rod are the same in shape. The left mounting base and the right mounting base each comprise two plates with holes, the two plates of the left mounting base are welded to a pulling plate of the first corrugated pipe, the two plates of the right mounting base are welded to a pulling plate of the second corrugated pipe, the left connecting rod is of a tubular structure, symmetrical openings are formed in the two sides of one end of the tubular structure, and symmetrical openings are also formed in theother end of the tubular structure. Rectangular plates are welded to the openings in the two end sides of the tubular structure.

Description

technical field [0001] The invention relates to the technical field of expansion joint auxiliary devices, in particular to an expansion joint anti-seize balance device. Background technique [0002] Introduction: Expansion joints are customarily also called compensators, or expansion joints. It consists of a bellows (an elastic element) that constitutes its main body and accessories such as end pipes, brackets, flanges, and conduits. The expansion joint is a flexible structure arranged on the container shell or pipeline in order to compensate the additional stress caused by temperature difference and mechanical vibration. Utilize the effective expansion and contraction deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate the axial, lateral and angular displacement of pipelines, conduits, containers, etc. It can also be used for noise reduction, vi...

AI Technical Summary

Problems solved by technology

In the application at the present stage, it often occurs that the upper and lower parts of the expansion joint are deformed unevenly, and in most cases the deformation is all concentrated in the lower part of the expansion joint, which causes excessive deformation of the lower bellows and damages the expansion joint. The internal heat insulation structure of the joint makes the expansion joint unable to work normally
