The invention discloses an electric millstone tile lifting appliance which is composed of a rigging turnbuckle, a lifting beam, a lifting appliance body, a connecting bolt, an electric hoist, a sleeve and a millstone tile, the millstone tile and the electric hoist are connected and fixed through the lifting appliance body, the other end of the electric hoist is fixed to the lifting beam, one end of the lifting beam is fixed to a medium-speed coal mill access door frame. The other end of the lifting beam is fixed on a middle frame body lifting lug, and electric hoisting of the millstone tile in a narrow space of the coal mill is achieved. The lifting tool body is composed of an upper cantilever, a lower cantilever and a connecting beam, a special structure is designed at one end of the lifting beam to be connected with a door frame of an access door of the coal mill, and the other end of the lifting beam is fixed to a sleeve welded on site on the lifting lug of the middle frame body of the coal mill. In order to adjust the balancing requirement, the hoisting beam and the sleeve are connected and fixed through the rigging turnbuckles, so that electric hoisting of the millstone tile in the coal mill is achieved. The labor input is reduced when the millstone tile is mounted and dismounted, the overhauling efficiency of the millstone tile is improved, and the overhauling cost of the medium-speed coal mill is reduced.

    本发明公开了一种电动磨盘瓦吊具,由索具螺旋扣、吊梁、吊具体、连接螺栓、电动葫芦、套管、磨盘瓦组成,吊具体将磨盘瓦与电动葫芦连接固定,电动葫芦另一端固定于吊梁上,吊梁的一端固定在中速磨煤机检修门门架上,另一端固定于中架体吊耳上,实现磨盘瓦在磨煤机狭小空间内的电动吊运,吊具体由上下悬臂及连接梁组成,吊梁一端设计专用结构与磨煤机检修门门架连接,另一端与磨煤机中架体吊耳上现场焊接的套管固定,为调整平衡需要,在吊梁与套管之间采用索具螺旋扣连接固定,实现了磨盘瓦在磨煤机内的电动吊运,在磨盘瓦的安装与拆卸时减少了人工投入,提高了磨盘瓦的检修效率,降低了中速磨煤机的检修成本。
