摘要
介绍了一种四卷筒抓斗卸船机卷筒单动换绳方法.该抓斗卸船机的小车运行电机、抓斗起升电机和抓斗开闭电机均采用变频电机,机构在停止制动状态时,人工断开非换绳侧的离合装置;通过控制小车运行电机和抓斗起升电机或者抓斗开闭电机的转速和旋转方向,利用行星差动减速器的差动原理,使设置在同一个行星差动减速器上的一个卷筒转速为零,另一个卷筒以合成速度旋转,实现纯电控换绳.该方法操作方便,可提高维保效率.
Abstract
A single movement rope changing method for the 4-drum grab ship unloader is introduced.The trolley running motor,grab lifting motor,and grab opening and closing motor of the grab ship unloader all use variable frequency motors.When the mechanism stops braking,the clutch device on the non rope changing side is manually disconnected;by controlling the speed and rotation direction of the car's running motor,grab lifting motor,or grab opening and closing motor,and utilizing the displacement measurement of planetary differential reducer,one drum set on the same planetary differential reducer is set to zero speed,while the other drum rotates at a synthetic speed,pure electric control rope changing is achieved.This method is easy to operate and can improve maintenance efficiency.
