Walking detection mechanism of centering instrument of continuous casting crystallizer

Abstract

The invention discloses a walking detection mechanism of a centering instrument of a continuous casting crystallizer, which comprises a walking control module, a walking mechanism and a detection module which are connected with the walking control module, a motor controlled by two positioning base lifting steel wire ropes of the walking control module and a positioning base with a telescopic function, a walking track of a detection unit composed of two steel wire ropes is erected in a target detection interval between an upper opening of a crystallizer and the lower portion of an inlet of a supporting and guiding section of a casting machine, and driving of a motor is controlled through the lifting steel wire ropes of the detection unit. And a detection unit connected by a detection unit lifting steel wire rope is driven to move up and down on the track, and a centering value in a detection area is detected and obtained. According to the invention, the influence of human factors on detection results in centering operation is solved, the labor intensity of field operation is reduced, and the storage reliability of centering measuring tools is improved.

Description

technical field [0001] The invention relates to the field of continuous casting automatic detection equipment, in particular to a running detection mechanism of a continuous casting crystallizer centering instrument. Background technique [0002] With the continuous development of continuous casting technology, the continuous improvement of product quality requirements in the steel market and the needs of steel mills to improve efficiency and control costs, domestic and foreign related companies are paying more and more attention to the radian of slab continuous casting machines. The precision requirements of the mold and support guide section of the traditional casting machine are consistent with the precision requirements of other areas, and the deviation is less than ±0.5mm. Some enterprises improve this precision to less than ±0.3mm or even higher requirements according to the requirements of quality control. [0003] The centering of the original crystallizer mainly rel...

Problems solved by technology

When using this kind of tool to measure, it is necessary to hoist the arc plate into the crystallizer by driving, and then one person drills into the casting machine, and two to three people on the top cooperate with the arc plate alignment. The gap between the monitoring points, because the space of the casting machine is very narrow, it is dangerous for personnel to drill into the casting machine itself, and at the same time, it is very difficult to detect because the hands and feet cannot be stretched. Positioning has a great impact, and these arc plates often have a certain amount of deformation due to factors such as on-site storage conditions, which will also lead to deviations in alignment accuracy
