The invention provides a crown block steel coil placement control method, and relates to the technical field of steel coil transportation, and the method comprises the following steps: setting a first measuring point on one side of a saddle; in the descending process of the steel coil, the distance D from the first measuring point to the lowest point of the bottom face of the steel coil and the elevation angle # imgabs0 # from the first measuring point to the lowest point of the bottom face of the steel coil are detected in real time, the vertical distance H from the lowest point of the steel coil to the horizontal plane where the first measuring point is located is calculated, and the H and the preset height # imgabs1 # are judged; when the steel coil is # imgabs2, the steel coil is controlled to stop descending; after the steel coil stops descending, the distance # imgabs3 # from the first measuring point to the lowest point of the bottom surface of the steel coil and the elevation angle # imgabs4 # from the first measuring point to the lowest point of the bottom surface of the steel coil are detected, the horizontal distance L from the first measuring point to the lowest point of the bottom surface of the steel coil is calculated, and whether the L is within the preset placement distance # imgabs5 # or not is judged. The device can detect the placing position of the steel coil in real time, and timely corrects when the placing position deviates from the saddle to ensure that the steel coil is safely placed on the saddle.
本发明提供了一种天车钢卷放置控制方法,涉及钢卷运输技术领域,方法包括:在鞍座的一侧设置第一测量点;在钢卷下降过程中,实时检测第一测量点到钢卷底面最低点的距离D以及第一测量点到钢卷底面最低点的仰角#imgabs0#,计算钢卷最低点到第一测量点所在水平面的垂直距离H,判断H与预设高度#imgabs1#的大小;当#imgabs2#时,控制钢卷停止下降;钢卷停止下降后,检测第一测量点到钢卷底面最低点的距离#imgabs3#以及第一测量点到钢卷底面最低点的仰角#imgabs4#,计算第一测量点到钢卷底面最低点的水平距离L,判断L是否处于预设放置距离#imgabs5#范围内。本发明能够实时检测钢卷放置位置,当放置位置偏离鞍座时及时修正,确保钢卷安全放置在鞍座上。
