Description

Technical Field

[0001] This invention belongs to the field of measurement technology, and in particular relates to a method for adjusting and measuring the position of a continuous casting machine support. Background Technology

[0002] During the adjustment and measurement of continuous casting machine supports using a laser tracker, each support needs to be adjusted and measured more than three times. Each support includes two trunnions and two support sides that need to be measured. Each time, at least 32 measuring points need to be measured for each support. Taking a three-strand special-shaped billet continuous casting machine of Baogang as an example, there are a total of 15 supports. At least 480 measuring points need to be measured once, and 1440 measuring points need to be measured three times. In addition, supports of different strands need to be continuously transferred to different stations for measurement. In total, more than 20 transfer measurements are required to complete the measurement work of the entire continuous casting machine, which is time-consuming and labor-intensive.

[0003] Comparative Reference 1 (CN2013103569626): This invention relates to a method and device for inspecting and measuring the base of a sector section of a continuous casting machine. It involves positioning a dummy shaft in a U-shaped seat, measuring parameters such as the dummy shaft elevation to measure the arc-shaped sector section and the straightening sector section, and then measuring the base of the sector section using a measuring device. Error compensation is used during the measurement process. The measuring device simulates the sector section. The advantages of this invention are: the measurement method is easy to implement, convenient to operate, accurate and fast, and improves the work period. Except for the measurement and adjustment of the No. 5 positioning U-shaped seat of the first arc-shaped sector section, which requires crossing the tangent line of the casting machine at the reference point, the measurement and adjustment of the positioning U-shaped seats of the remaining sector sections can be done using an inside micrometer, a level, or an indium steel ruler, avoiding the need to cross the tangent line of the casting machine at the reference point for the remaining positioning U-shaped seats. This fixture can only be used for the inspection and adjustment of slab continuous casting machines.

[0004] Comparative Reference 2 (CN201420309693.8): A measuring tool for the sector-shaped support of a continuous casting machine, belonging to the field of continuous casting machine arc detection technology. This device includes three parts: a positioning boss, a detection hole, and a positioning flange. The positioning boss, detection hole, and positioning flange are machined as a single unit. The positioning flange is located on the upper part of the positioning boss, and the detection hole is located at the center of the positioning flange and the positioning boss, penetrating both. Its advantage lies in solving the problem of inaccurate detection data, such as large deviations in the measured and fitted values, caused by difficulties in close contact between the spherical prism and the detection surface, and the detection points not being on the same cross-section when directly detecting the center of the positioning support of the sector-shaped support structure of a continuous casting machine. This tooling can reduce the number of measurement points and improve measurement efficiency, but it can only reduce the number of measurement points by half. Moreover, when the trunnion copper sleeve is severely deformed, the measurement results obtained using this tooling have a large deviation.

[0005] Comparative Reference 3 (CN2023102139910): This invention relates to a digital rapid adjustment method for the foundation frame of a slab continuous casting machine's sector segment, comprising the following steps: S1, importing design standard values; S2, installing and adjusting the support seats of the sector segment foundation frame; S3, installing the support of the "0" segment frame; S4, positioning the sector segment foundation frame; S5, adjusting the support of the "0" segment frame; S6, measuring the sector segment foundation frame; S7, fine-tuning the sector segment foundation frame; S8, grouting the support seats of the sector segment foundation frame. This invention uses a total station to collect the coordinate values ​​of the positioning plate (non-fixed side) and U-shaped seat (fixed side) of the support seat and sector segment foundation frame, and inputs them into the continuous casting installation foundation frame adjustment calculation software for comparison with the design standard values. It outputs the analyzed deviation values ​​and drawings, which visually represent the adjustment values ​​and directions, achieving rapid and accurate adjustment. However, using this tooling for measurement still requires the use of instruments to measure a large number of points. Summary of the Invention

[0006] To address the problem that current continuous casting machine support adjustment and measurement processes require adjusting and measuring numerous measuring points for each support, necessitating frequent station transfers and resulting in significant time and labor costs, this invention aims to provide a method for adjusting and measuring the position of continuous casting machine supports. This invention utilizes a laser tracker for measurement and solves the problems associated with current laser tracker measurement processes by attaching two control points at corresponding positions on the continuous casting machine support.

Moreover, only two measurement points need to be measured each time, so this invention saves time and effort and reduces safety risks during the measurement process. Attached Figure Description
