The invention relates to the technical field of cranes, and discloses a method for preventing winding drum steel wire ropes from being disordered in grooves for a grab bucket crane, which comprises the following steps: S1, a grab bucket moves to a position right above a to-be-grabbed material under the action of a cart and a trolley; s2, the grab bucket is opened and falls down; s3, measuring and calculating a coordinate deviation value s1 of the grab bucket and the cart, and transmitting the coordinate deviation value s1 to a crane control system; s4, measuring and calculating a coordinate deviation value s2 of the grab bucket and the trolley, and transmitting the coordinate deviation value s2 to the travelling crane control system; s5, the crane control system correspondingly controls the cart and the trolley to move according to the coordinate deviation value; and the steel wire rope is perpendicular to the winding drum on the trolley. According to the method, displacement supplement is carried out on the cart and the trolley in advance, and groove disorder caused by the too large deflection angle of the steel wire rope in the vertical direction during hoisting is avoided.
本发明涉及起重机技术领域,公开一种抓斗行车防止卷筒钢丝绳乱槽的方法,包括以下步骤:S1:抓斗在大车以及小车作用下,移动至待抓取物料的正上方;S2:抓斗张开并下落;S3:测量并计算抓斗与大车的坐标偏差值s1并传输给行车控制系统;S4:测量并计算抓斗与小车的坐标偏差值s2并传输给行车控制系统;S5:行车控制系统根据坐标偏差值,对应控制大车以及小车移动;消除钢丝绳垂直偏角,使钢丝绳与小车上的卷筒垂直。本方法通过提前对大车以及小车进行位移补充,避免了起吊时因钢丝绳在垂直方向的偏角过大而导致乱槽。
