The lifting appliance comprises a main shaft, the upper portion of the main shaft is sleeved with a sliding block, the sliding block is movably connected with the main shaft, and the lower portion of the main shaft is sleeved with a fixing base; the upper portion and the lower portion of the fixing base are both connected with a plurality of supporting pieces, one ends of the supporting pieces connected with the upper portion of the fixing base are hinged to the fixing base, the other ends of the supporting pieces connected with the lower portion of the fixing base are hinged to the upper portion of the supporting block, one ends of the supporting pieces connected with the lower portion of the fixing base are hinged to the fixing base, and the other ends of the supporting pieces are hinged to the lower portion of the supporting block. The side edges of the fixed seat, the two supporting sheets and the supporting block can form a parallelogram or rectangular frame body; each supporting piece is connected with a sliding piece, the bottom end of each sliding piece is hinged to the middle of the corresponding supporting piece, and the top end of each sliding piece is hinged to the corresponding sliding block; by means of a pure mechanical structure, use of an air cylinder and an electric cylinder is avoided, when the stator is grabbed, the upper supporting piece, the lower supporting piece, the fixing base and the supporting block are rectangular, and it is guaranteed that gravity is converted into clamping force to clamp and hoist the motor stator to the maximum extent.
本发明公开一种抓取电机定子的吊具及方法,包括主轴,主轴上部套入滑动块内,滑动块与主轴活动连接,主轴下部套入固定座内;固定座的上部及下部均连接多个支片,与固定座上部连接的支片的一端与固定座铰接连接,另一端与支撑块的上部铰接连接,与固定座下部连接的支片的一端与固定座铰接连接,另一端与支撑块的下部铰接连接,固定座的侧边、两个支片及一个支撑块可形成平行四边形或矩形的框体;每个支片连接一个滑动片,滑动片的底端与支片的中部铰接连接,滑动片的顶端与滑动块铰接连接;本发明通过纯机械结构,避免了气缸和电缸的使用,抓取定子时,上支片、下支片、固定座、支撑块四者呈矩形,保证重力最大化转化为夹紧力夹持吊起电机定子。
