The invention discloses an automatic positioning roller lifting appliance, and relates to the technical field of hot rolling strip steel in the metallurgical industry, the automatic positioning roller lifting appliance comprises a lifting appliance device and a positioning device, and the lifting appliance device comprises a lifting frame, a supporting frame, a fixing column, a rotating part, a clamping plate, a second hydraulic cylinder, a fixing plate and a pressing plate. The hydraulic cylinders can drive the clamping plates to clamp a roller, the non-slip mats can increase the friction force between the clamping plates and the surface of the roller, the clamping plates can clamp the roller more stably, the third hydraulic cylinder can drive the pressing plate to clamp the roller, the second hydraulic cylinder can drive the pressing plate to press the roller downwards, and therefore the roller is clamped and fixed in all directions; the shaking amplitude of the roller during hoisting is reduced, the stability and safety of the roller during hoisting are enhanced, when the positioning device clamps and fixes the roller, the positioning rod automatically moves downwards, the placement position of the roller is conveniently positioned, meanwhile, when the roller is put down, the positioning rod automatically moves upwards, and the positioning precision of the roller during descending and putting down is improved; and the precision requirement of roller hoisting is met.
本发明公开了一种自动定位轧辊吊具,涉及冶金行业热轧带钢技术领域,包括吊具装置和定位装置,所述吊具装置包括吊架、支撑架、固定柱、转动件、夹板、液压缸二、固定板和压板。本发明通过液压缸可带动夹板将轧辊夹持住,防滑垫可增大夹板和轧辊表面摩擦力,使夹板对轧辊的夹持更加稳固,通过液压缸三可带动压紧板将轧辊夹紧,通过液压缸二可带动压板向下将轧辊压紧,从而将轧辊全方位地夹持固定,降低轧辊在吊运时的晃动幅度,增强轧辊在吊运时的稳定性和安全性,定位装置对轧辊夹持固定时定位杆自动向下移动,方便对轧辊放置的位置进行定位,同时在轧辊放落时定位杆自动向上移动,提高轧辊在下降放下时的定位精度,满足轧辊吊运的精度要求。
