The invention discloses a lifting device, a mixing plant and a lifting device control method. The lifting device comprises a lifting track, a lifting hopper, a hoisting mechanism and a control module. The lifting hopper is movably arranged on the lifting track; the hoisting mechanism is used for driving the lifting hopper to lift; the control module is internally provided with preset ascending time and preset descending time, and is used for timing when the hoisting mechanism starts to ascend, controlling the hoisting mechanism to stop when the hoisting mechanism does not stop when the ascending time of the hoisting mechanism reaches the preset ascending time, timing when the hoisting mechanism starts to descend, and when the descending time of the hoisting mechanism reaches the preset descending time and the hoisting mechanism is still not stopped, controlling the hoisting mechanism to stop. According to the lifting device, the mixing plant and the control method of the lifting device, in the ascending or descending process of the lifting hopper, due to the fact that the hoisting mechanism can be controlled to stop when the hoisting mechanism operates for a time exceeding the preset time, the probability that the lifting device rushes to the top or rolls back can be reduced, and therefore the operation safety is greatly improved.
本发明公开一种提升装置、搅拌站及提升装置控制方法,该提升装置包括提升轨道、提升料斗、卷扬机构和控制模块;提升料斗可移动地设于提升轨道上;卷扬机构用于驱动提升料斗升降;控制模块内设有上升预设时间和下降预设时间,控制模块用于在卷扬机构开始上升时计时,当卷扬机构的上升时间达到上升预设时间仍未停止时控制卷扬机构停机,在卷扬机构开始下降时计时,当卷扬机构的下降时间达到下降预设时间仍未停止时控制卷扬机构停机。本发明的提升装置、搅拌站及提升装置控制方法中,在提升料斗上升或下降过程中,由于卷扬机构运行超过预设时间时会控制卷扬机构停机,可降低提升装置冲顶或反卷的发生几率,从而大大提高运行的安全性。
