The invention relates to the technical field of expansion joints, in particular to an expansion joint high-precision measuring device which comprises an arc-shaped rail assembly arranged in the circumferential direction of an expansion joint, a limiting rod arranged in the axial direction of the expansion joint, an installation assembly and at least one testing device arranged on the installationassembly. The installation assembly can move on the track assembly along an arc and drive the testing device to rotate in the circumferential direction of the expansion joint, the testing device can move on the limiting rod in the axial direction of the expansion joint, the track assembly comprises two guide rails which are arranged in a spaced mode, and transmission rods are arranged on the two guide rails. The installation assembly comprises two bases corresponding to the two guide rails, the two bases slide in the rail direction and are stopped and positioned on the corresponding guide rails in other directions, and transmission blocks corresponding to the transmission rods are installed on the two bases.
Description
technical field [0001] The invention relates to the technical field of expansion joints, in particular to a high-precision measuring device 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, commonly used structures such as corrugated, ring-plate welded and sandwich structures, among which corrugated expansion joints are the most widely used, and ring-plate welded expan...
