Problems solved by technology
2) When the initial steel coil is not in the center position, there is no detection and alarm during transportation
3) Cannot automatically adjust the center position of the trolley when unloading rolls
4) Spillage inside and outside the export steel coil will lead to unstable center of gravity or edge scraping, resulting in rollover accidents
There are major defects in this technology: the steel coil belongs to the layer-by-layer coiling of the steel strip, and its axial surface is uneven and has many burrs, which is not an ideal plane
Once the detection error occurs, a rollover accident will be fatal

The invention provides a steel coil trolley coil unloading centering automatic adjusting device and method.The device comprises a distance measuring mechanism and a PLC, the distance measuring mechanism comprises a laser distance measuring instrument and a photoelectric sensing assembly, and the photoelectric sensing assembly comprises a first photoelectric sensor, a second photoelectric sensor, a first light reflecting plate and a second light reflecting plate; the laser range finder and the coil receiving side end face of a base of the steel coil trolley are horizontally arranged, the first photoelectric sensor and the second photoelectric sensor are vertically and symmetrically arranged on one side of the steel coil trolley conveying channel through sensor supports, and the first reflector and the second reflector are vertically and symmetrically arranged on the other side of the steel coil trolley conveying channel through reflector supports. The input end of the PLC is connected with the laser range finder, the first photoelectric sensor and the second photoelectric sensor through cables, the output end of the PLC is connected with a driving unit of the steel coil trolley through a cable, automatic adjustment of the steel coil trolley is achieved, and it is guaranteed that a steel coil is placed in the center of the transition saddle.
Description
technical field [0001] The invention belongs to the technical field of steel coil transportation, and in particular relates to an automatic adjustment device and method for unloading and centering of a steel coil trolley. Background technique [0002] There are many steel coil transportation trolleys in the production line of the metallurgical industry, which are used to realize the automatic transportation between the steel coil and the walking beam (or the large transportation chain). The width of the saddle of the trolley is generally larger than the width of the steel coil, and the walking beam needs to be inserted into the transition saddle to connect the coil, so the width of the saddle of the walking beam is generally only 1 / 4 to 1 / 3 of the width of the steel coil. In the process of transferring the steel coil, if the steel coil is not placed in the middle of the transition saddle, it will tilt when it is transferred to the saddle of the walking beam (or transport lar...
