摘要
Abstract
Electric hoist is a common industrial lifting machinery equipment.Although its work efficiency is high,the motor has no overload protection and is burned easily.And it has the possibility of leakage electricity,so that it does not apply to explosion-proof occasions.A new kind of air hoist is put forward which adopts compressed air as the power source and based on the pneumatic directional control valve of the main valve core movement to realize overload protection.The mechanical structure,operating principle and characteristic parameter of the air hoist are also introduced.The AMESim and the experiment research of the pneumatic system circuit are also conducted.Simulation test shows that the device with pneumatic way can not only achieve weight smooth starting and braking,and effectively avoid the risk of hoist derailment fall,but also can achieve the goal of overload protection.关键词
