The invention relates to a grab bucket type unmanned crown block material taking method, and belongs to the technical field of crown block control methods. According to the technical scheme, the lifting position is detected, speed reduction is conducted in advance before a material surface is reached, and a grab bucket makes contact with the material surface at a low speed; the grab bucket starts to be closed after making contact with the material face, the lifting motor is started again to descend for the second time when the grab bucket is closed by a certain distance, and the secondary descending distance is that the secondary descending speed is matched with the opening and closing speed. The grab bucket has the beneficial effects that the lifting steel wire rope is not loosened all the time, it is guaranteed that the grab bucket does not incline in the closing process, the grabbing amount of each time can be guaranteed, the problem that the steel wire rope disengages from a groove under the action of lateral force can be avoided, and the grab bucket has the characteristics of applicability, safety and high efficiency.

    本发明涉及一种抓斗式无人天车取料方法,属于天车控制方法技术领域。本发明的技术方案是:检测升降位置,到达料面前提前减速,使抓斗以低速接触料面;抓斗接触料面后开始闭合,在闭合到一定距离时再次启动升降电机二次下降,二次下降距离为,二次下降速度,与开闭速度匹配。本发明的有益效果是:使升降钢丝绳始终不松弛,保证抓斗在闭合过程中不歪斜,这样既能保证每次的抓料量,又能避免钢丝绳在侧向力作用下的脱槽问题,具有适用性、安全性、高效性的特点。
