The invention provides a portable lifting appliance for replacing a grinding wheel of a grinding machine and a using method of the portable lifting appliance, belongs to the technical field of grinding wheel replacing equipment, and solves the problems that the operation activity frequency of replacing the grinding wheel after the grinding wheel is worn to a certain extent is high, and an original grinding wheel lifting appliance has safety risks, high labor intensity and long consumed time. The main body frame is formed by connecting a cross rod and a vertical rod, the cross rod and the vertical rod are connected at an acute angle, the end part of the cross rod is connected with a lifting lug sleeve, a swinging lifting lug is sleeved in the lifting lug sleeve, the upper part of the swinging lifting lug is provided with a through hole, the bottom of the swinging lifting lug is provided with a boss, and the hanging groove and the vertical rod are connected at an obtuse angle; the method further comprises the following steps that a swing lifting lug is inserted into a lifting lug sleeve, and a shackle of a cantilever crane penetrates through a through hole to be hoisted to the grinding wheel; hanging the hanging groove into a half circle of boss of the grinding wheel; and the whole grinding wheel is hoisted into the grinding machine grinding wheel spindle box by operating the cantilever crane. According to the method, the safety risk of the operation is reduced, the time of the whole operation is effectively shortened, and the roller grinding efficiency is effectively guaranteed.
本发明提供了一种用于磨床砂轮更换的轻便型吊具及其使用方法,属于砂轮换装设备技术领域,解决了因砂轮磨损到量后更换砂轮的作业活动频次高,原有砂轮吊具存在安全风险和劳动强度大、耗时较长的问题,本发明包括由横杆和竖杆连接的主体框架和挂槽,横杆和竖杆成锐角连接,横杆端部连有吊耳套筒,吊耳套筒内套设有摆动吊耳,摆动吊耳上部开设有通孔,摆动吊耳底部设有凸台,挂槽与竖杆成钝角连接;还包括以下步骤:将摆动吊耳插入吊耳套筒内,将悬臂吊的卸扣穿入通孔吊至砂轮处;将挂槽挂入砂轮的半圈凸台内;操作悬臂吊将砂轮整体吊入磨床砂轮主轴箱内。本发明降低了此项作业的安全风险,还有效缩短了整个作业的时间,有效保证了轧辊磨削效率。
