Abstract

The invention relates to the technical field of expansion joint machining, in particular to a height-adjustable supporting frame for an expansion joint. The height-adjustable supporting frame comprises a supporting frame body and a fixed base, wherein a connecting rod is mounted at the upper end of the supporting frame body, mounting holes are formed in the supporting frame body, mounting frames are arranged in the mounting holes, and bolt holes are formed in the mounting frames. The mounting frames are connected with fixing clamping blocks through fixing pins, the fixing clamping blocks are connected with a supporting plate through locking pins, the supporting plate is fixed to an auxiliary frame body, a limiting groove is formed in the auxiliary frame body, lead screws are arranged in the limiting groove, a sliding block is installed on the lead screws, and the fixed base is installed at the lower end of the lead screw.

Description

technical field [0001] The invention relates to the technical field of expansion joint processing, in particular to a height-adjustable support frame for expansion joints. Background technique [0002] Introduction: An expansion joint is a flexible element that can effectively compensate for axial deformation. For example, the expansion joint welded on the shell of a fixed tube-sheet heat exchanger has large axial flexibility and is easy to deform. It can compensate the thermal expansion difference between the tube and the shell due to different wall temperatures, reduce their axial load, and reduce the tube load. , The temperature difference stress between the tube sheet and the shell, to avoid causing strength damage, instability damage and tube pull-off damage. There are many types of expansion joints, and the commonly used structures are corrugated, ring-plate welded and sandwich-type. Among them, corrugated expansion joints are the most widely used, and ring-plate weld...
