Position detection device and method for steel roll system

Abstract

The invention discloses a position detection device and method for a steel roll system. The device comprises a total station, a reference landmark and a marker post, wherein the marker post comprisesa marker post arm, a prism, a slide block and a vacuum suction disc, the total station is bridged on one sides of the reference landmark and a to-be-measured roll shaft, the prism is fixedly connectedto the top of the marker post, the marker post arm can move up and down along the slide block and is positioned through a positioning pin, and the slide block is fixedly connected to the vacuum suction disc. The position detection device has the advantages that multiple parameter indexes of a single roll and the roll system can be simultaneously detected by virtue of the whole set of a measurement device; and by utilizing an adaptive threshold adjustment algorithm, the accuracy and fitting speed of a traditional spatial circle fitting algorithm are increased, and the device can be used for guiding the correction of the roll system, so that the productivity, quality and benefit of a product are greatly increased.

Description

technical field [0001] The invention relates to a measuring device and method, in particular to a steel roll position detecting device and method. Background technique [0002] Due to the long-term high-speed operation of the steel roll system, its verticality, horizontality and other spatial positional relationships will gradually change, resulting in problems such as wrinkling, deviation, overflow and poor product shape of the steel coil, directly affecting production capacity, quality and efficiency . Therefore, it is required to measure the spatial position of the roller system to obtain offsets such as horizontality and verticality, so as to adjust the position of the roller shaft. The traditional method of measuring with a steel ruler level is often used in actual measurement, but it has gradually withdrawn from the stage of history due to its limited accuracy and limited use environment; the method based on laser measurement is to form a reference laser and a detecti...

Problems solved by technology

For a long time, technicians have summed up the evaluation criteria of the roll system with horizontality and verticality as the main reference indicators, but the design of the measurement device and data processing algorithm of the roll system position detection system is still not perfect
