The invention relates to an automatic positioning roller lifting appliance and a use method and belongs to the technical field of hot-rolled strip steel in the metallurgical industry. According to thetechnical schemes of the invention, a guide sleeve (2) is installed on a crane trolley (3); a guide rod mechanism (1) is installed on a lifting appliance (4); a guide sleeve on the crane trolley is located over the guide rod mechanism on the lifting appliance; and the guide rod mechanism (1) is matched with the guide sleeve (2) in shape. With the automatic positioning roller lifting appliance andthe use method of the invention adopted, shaking in a hoisting process is avoided; descending operation can be started immediately after a crane reaches a designated position and stops; the shaking problem of the lifting appliance at the highest position during starting, running and stopping does not need to be considered; and transportation efficiency is improved with equipment precision guaranteed.
本发明涉及一种自动定位轧辊吊具及使用方法,属于冶金行业热轧带钢技术领域。技术方案是:所述导向套筒(2)安装在起重机小车(3)上,导杆机构(1)安装在吊具(4)上,起重机小车上的导向套筒位于吊具上的导杆机构正上方,导杆机构(1)和导向套筒(2)形状相匹配。本发明避免在吊运过程中的晃动,在起重机到达指定位置停止后,可立即启动下降操作,无须考虑吊具在最高位的启动、运行、停止时的晃动问题,在保证设备精度的情况下,提高了运输效率。
