The electromagnetic lifting appliance comprises a main cross beam, the two ends of the main cross beam are symmetrically connected with a plurality of electromagnets through chains, the two ends of the main cross beam are further symmetrically connected with at least one pair of anti-rolling mechanisms through chains, and each anti-rolling mechanism comprises a vertical linkage shaft; one end of the vertical linkage shaft is connected with a turbine, the other end of the vertical linkage shaft is connected with a horizontal gear, the turbine is in meshed connection with a worm and is driven by a motor, the horizontal gear is in transmission connection with the two swing arms through a rack assembly, the rack assembly comprises two rack sliding blocks arranged in parallel, and vertical racks are arranged on the upper end faces of the rack sliding blocks; a horizontal rack is arranged on the inner side face of the rack sliding block, and the rack sliding block is connected into the sliding rail in a sliding mode. After the round billet is lifted to be separated from the ground, a motor drives a worm to enable a turbine to drive an internal gear rack to operate, a swing arm of an anti-rolling mechanism is driven to be folded, and the round billet is limited and prevented from rolling.

    本发明公开了一种具有防滚动机构的电磁吊具,包括主横梁,所述主横梁的两端通过链条对称连接有若干电磁铁,所述主横梁的两端还通过链条对称连接至少一对防滚动机构,所述防滚动机构包括竖直联动轴,所述竖直联动轴的一端连接涡轮,另一端连接水平齿轮,所述涡轮啮合连接蜗杆并通过电机驱动,所述水平齿轮通过齿条组件传动连接两个摆臂,所述齿条组件包括两个平行设置的齿条滑块,所述齿条滑块的上端面设有垂直齿条,所述齿条滑块的的内侧面设有水平齿条,所述齿条滑块滑动连接于滑轨中。圆坯被吊起脱离地面后,电机驱动蜗杆使涡轮带动内部的齿轮齿条进行运转,带动防滚动机构的摆臂收拢,对圆坯进行限位防止滚动。
