The invention discloses a steel coil feeding dolly height centering apparatus and a method thereof, and belongs to the technical field of strip coil finishing control. The apparatus comprises a hydraulic cylinder, an upper limit switch, a lower limit switch, an optoelectronic switch and a magnetic ruler, wherein the hydraulic cylinder is fixed on a feeding dolly, the magnetic ruler is in the hydraulic cylinder, the upper limit switch is fixed in the upper limit position of the saddle of the feeding dolly, the lower limit switch is fixed in the lower limit position of the saddle of the feeding dolly, and the optoelectronic switch is on the fixed support of the feeding dolly. In the invention, the dolly height centering distance is automatically obtained by calculating through the geometric composition of a machine position and a sensor position, so a severe accident caused by mechanical bumping or dropping because of the inappropriate steel coil position caused by manually-operated adjustment is avoided, the position control precision of the feeding dolly is guaranteed, and the feeding speed of a flat line is improved.
Description
technical field [0001] The invention belongs to the technical field of coil finishing control, and in particular relates to a height centering device and a method for a steel coil feeding trolley. Background technique [0002] The field of strip steel finishing has been paid more and more attention by major steel mills to improve the added value of products and meet the requirements of different customers. The leveling line is one of the product finishing production lines. Steel coil feeding has become an important link that restricts leveling production capacity. At present, most steel coil feeding is manually controlled. The steel coil feeding trolley is manually controlled to lift and the height is adjusted manually Align the mandrel of the uncoiler, when the center of the steel coil is consistent with the center of the mandrel, then manually control the steel coil feeding trolley to move forward, and load the steel coil into the mandrel. This process is quite a test of ...
