The invention provides a special rotating and overturning lifting appliance for profiles. An upper hanging frame is rotatably connected with a middle hanging frame; the upper end of a lower hanging frame is fixed to the middle hanging frame; each overturning electromagnet system comprises two magnet overturning driving wheels, two chains, two magnet overturning driven wheels and an electromagnet,wherein the two chains are arranged on the magnet overturning driving wheels and the two magnet overturning driven wheels on the corresponding sides in a sleeving manner and are respectively meshed with the magnet overturning driving wheels and the two magnet overturning driven wheels, and the two ends of the electromagnet are fixedly connected with the two magnet overturning driven wheels respectively. The special rotating and overturning lifting appliance has the advantages that through rotation of the lifting appliance and turnover of the electromagnets, the adsorption surfaces of the electromagnets are matched with the pre-adsorption surfaces of the lifted profiles or parts before adsorption, so that uncontrollable factors such as swinging and even falling of the lifted profiles or parts in the lifting process are avoided; an operator can operate remotely; and the operation safety is greatly improved, and the safety coefficient of the operator is improved.
本发明提供一种型材专用旋转翻转吊具,上挂架与中间挂架可旋转连接;下挂架的上端固定在中间挂架上;每个翻转电磁铁系统包括,两个磁铁翻转主动轮、两条链条、两个磁铁翻转从动轮和电磁铁;两条链条分别套在对应一侧的磁铁翻转主动轮、两个磁铁翻转从动轮上,且与两者分别啮合;电磁铁的两端分别与两个磁铁翻转从动轮固定连接。其优点在于通过吊具旋转和电磁铁的翻转,实现电磁铁吸附面与被吊型材或部件的预吸附面在吸附之前就已经匹配好,从而避免诸如被吊型材或部件在吊装过程中的摆动甚至掉落等不可控因素;操作人员可以远距离操作;大大增加操作的安全性,提高操作人员的安全系数。
