Arc detection method for slab casting machine based on holographic method

Abstract

The invention provides an arc detection method for a slab casting machine based on a holographic method, belonging to the technical field of measurement control. The method comprises the following process steps: erecting a total station in the middle of a horizontal section III of a sector section supporting frame, and ensuring that all sector section supports can be observed through the instrument; transforming coordination systems; and acquiring the coordinates of supporting positions of the supports and simulating the positions. The industrial grade total station is utilized to detect the arc section of the slab casting machine in combination with sphere prisms, and the method is used for detecting the arc of the casting machine during the installation and maintenance of the casting machine so as to determine the adjustment quantity of each support, thereby ensuring the arc to achieve the ideal state. By comprehensively acquiring the raw data of the acting surfaces of the supports and utilizing a computer model to simulate the deviation states of the measuring positions, the problem of how to accurately position all the positions of the supports on the sector section of the slab casting machine is solved. The method has the following advantages: by knowing the sector section supporting structure, the industrial grade total station is utilized to detect the arc section of the slab casting machine in combination with the sphere prisms; and the arc adjusting efficiency and accuracy are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of measurement and control, and in particular provides a holographic method for detecting the arc of a slab continuous casting machine (Danielli). The arc of the slab continuous casting machine can be detected by using an industrial-grade total station combined with a spherical prism. The segment is fully inspected. Background technique [0002] Due to the complexity of the structure of the slab continuous casting machine and the high-precision requirements for equipment positioning, the steel wire micrometer method is usually used to detect the arc in previous projects, which has problems such as complicated methods and low precision, and the theodolite and the level are frequently used. Erecting and turning points lead to the accumulation of errors during measurement, which reduces the measurement accuracy; when the more advanced method uses the total station to detect the sector support, it directly uses ...

[0002] Due to the complexity of the structure of the slab continuous casting machine and the high-precision requirements for equipment positioning, the steel wire micrometer method is usually used to detect the arc in previous projects, which has problems such as complicated methods and low precision, and the theodolite and the level are frequently used. Erecting and turning points lead to the accumulation of errors during measurement, which reduces the measurement accuracy; when the more advanced method uses the total station to detect the sector support, it directly uses the reference hole given by the design, and the result is only indirect The state of the support, so the accuracy of arc adjustment is not ideal
