The invention discloses a method for preventing a cable crane hook from swinging. The method comprises the following steps of calculating a single swing period according to a lifting height; correcting the single swing period according to a lifted weight; judging whether acceleration or deceleration is required according to a given speed and a current speed; if acceleration is required, taking anaverage value of the given speed and the current speed as an intermediate speed, correcting the intermediate speed and transmitting the corrected intermediate speed to a traction mechanism, wherein the traction mechanism is accelerated to run until a traction speed is equal to the corrected intermediate speed; then enabling the traction mechanism to run at a constant speed, wherein the time for running at the constant speed is 1/4 of the single swing period; and finally transmitting the given speed to the traction mechanism, wherein the traction mechanism is accelerated to run until a tractionspeed is equal to the given speed. The method has the beneficial effect of effectively realizing swing prevention of the hook.
本发明公开了一种缆索起重机吊钩防摇摆的方法,包括以下步骤:根据起升高度计算单摆周期;根据吊重量修正单摆周期;根据给定速度和当前速度判断需要进行加速或减速;若需要加速时,给定速度和当前速度的平均值作为中间速度,对中间速度进行修正并将修正后的中间速度传送给牵引机构,牵引机构加速运行直至牵引速度等于修正后的中间速度;然后牵引机构匀速运行,匀速运行的时间为1/4个单摆周期;最后将给定速度传送给牵引机构,牵引机构加速运行直至牵引速度等于给定速度。本发明有益之处在于有效实现吊钩的防摇摆。
