Embodiment 1

[0019] see Figure 1-3 , in the embodiment of the present invention, a device for measuring the parallelism of the two ends of the expansion joint, including a bracket 1 for erecting on the upper port of the expansion joint, and the bracket 1 is provided with a bracket for fixing it on the upper end of the expansion joint Positioner, at least two sliding columns 2 are slidably fitted on the bracket 1, each of the sliding columns 2 is screwed with a tightening bolt used to limit its position, and the bottom of the sliding column 2 is provided with a distance detection Block, the distance detection block here includes a high-precision ranging sensor 7 for measuring the distance between it and the plane where the lower end of the expansion joint is located and a displacement measurement sensor 8 for detecting the distance between two sliding columns 2, the distance detection The output end of the block is electrically connected to the calculator 3 for processing the data through ...

Embodiment 2

[0025] In order to facilitate the bracket 1 to accurately find the maximum inclination angle of the upper end of the expansion joint, the positioning piece is replaced with a support piece, the support piece includes a support plate for press contact with the upper end surface of the expansion joint, and the upper end of the support plate is rotated. There is a support ring, the diameter of the upper end of the support ring is provided with an installation area that is convenient for erection of the support 1, and a counterweight is provided at one end of the support 1, when testing, only need to place the support plate on the upper port of the expansion joint , under the action of gravity, the support 1 will drive the support ring to rotate, so as to find the maximum inclination angle of the upper end surface of the expansion joint, and then cooperate with the distance detection block and calculator to complete the measurement of the angle. Here, the support is set without meas...

Abstract

A device for measuring parallelism of two end faces of an expansion joint disclosed by the present invention comprises a support used for being erected on an upper port of the expansion joint, the support is provided with a positioning piece used for fixing the support on the upper end face of the expansion joint, the support is in sliding fit with at least two sliding columns, and the bottoms of the sliding columns are provided with distance detection blocks. The distance detection block comprises a high-precision distance measuring sensor used for measuring the distance between the distance detection block and the plane where the lower end of the expansion joint is located and a displacement measuring sensor used for detecting the distance between the two sliding columns, and the output end of the distance detection block is electrically connected with a calculator used for processing data through a data line. The method is designed according to the existing needs, the measurement efficiency of the parallelism of the two end faces can be improved, the accuracy is high, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a device for measuring the parallelism of two ends of an expansion joint. Background technique [0002] During the inspection of equipment, especially the inspection of expansion joints, the parallelism of the two ends of the expansion joints should be tested. The current detection method is to place the expansion joint on the platform first, with one end face down and the other end face up, use a metal ruler to determine two points corresponding to the diameter of the top end face of the expansion joint, and then measure the distance from the two points to the platform The difference is to measure the maximum distance difference. This measurement is time-consuming and laborious, and the measurement data is not accurate. Contents of the invention [0003] The object of the present invention is to provide a device for measuring the parallelism of the two end surfac...
