Embodiment Construction

[0024] The specific implementation manners of the application of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] figure 1 It shows the main part of the digitized three-way displacement measuring device provided by the application of the present invention, and the dustproof soft cover is not shown in the figure.

[0026] Among them, the three-way reflector 2 is fixed together by three square reflective panels with grid scales, and the installation and fixing part 1 of the three-way reflector 2 is fixed on the measured object that needs to detect the expansion displacement. The plane of the reflector 2 is usually parallel to the front, back, left, and right directions of the factory building, and the other direction is the vertical direction. The measured objects that need to detect expansion displacement on thermal equipment usually include cold wall headers, downcomers, high temperature superheater inlet headers,...

Abstract

The invention provides a digital three-way displacement measuring device for expansion monitoring of thermal equipment, which consists of a three-way reflector composed of three mutually perpendicular plates fixed on the object to be monitored, and a three-way laser fixed on a relatively static point. Composed of ranging sensors and soft dust-proof shields, it realizes the digitalization and precision of the detection process. The detection process is basically not affected by changes in environmental factors. The measurement accuracy is high and the data is stable and reliable. There is no zero drift problem in long-term operation; A method for controlling errors during on-site installation.

Description

technical field [0001] The application of the present invention relates to three-way displacement measurement technology, in particular to a digital three-way displacement measurement device that can be used for thermal equipment expansion measurement and an installation error control method thereof. Background technique [0002] Thermal equipment will expand and shrink due to changes in temperature and pressure. The specific value of deformation can reflect whether the equipment is abnormal. Therefore, it is necessary to monitor the specific value of expansion. However, at present, the operators of the power station mainly use manual inspection and recording methods to monitor, which is not only time-consuming and laborious, but also cannot be monitored in time, and it is not convenient to record and display the expansion trend for a long period of time. [0003] Patent application 201521101932.1 discloses a three-dimensional positioning mechanism composed of base, guide ra...
