摘要
Abstract
Screw hoist in the daily use of the decline process,the phenomenon of screw bending occurs from time to time.The main reason is that some large hard objects at the bottom of the sluice gate or the sluice gate groove are not easy to be detected by the operation management personnel.If the hard objects are not cleaned up in time,it will lead to slow or even stagnation of the sluice gate operation.The existing protection system is difficult to achieve timely and accurate action.As a result,the screw will be bent to different degrees.By directly tracking the real-time displacement speed of the sluice gate,using PLC to quickly and accurately measure the speed,and timely action to power down when the screw hoist is abnormal,the occurrence of the above phenomenon can be effectively avoided.关键词
