The invention relates to the technical field of maintenance, in particular to a fixed-width press main transmission cardan shaft rapid replacement method which comprises the steps that a special lifting appliance is manufactured; flange bolts, connected with the sliding bed, of the main transmission universal shaft are detached, and a lower cross bag of the main transmission universal shaft is contracted upwards through a lifting bolt; the special lifting appliance is lifted by a travelling crane, so that an upper transverse plate of the special lifting appliance is located above the speed reducer, the upper surface of a lower transverse plate of the special lifting appliance is in contact with the lower surface of the main transmission universal shaft, when the lifting appliance is stressed, lifting of the special lifting appliance is stopped, and an anchor bolt at the joint of the main transmission universal shaft and the output end of the speed reducer is dismounted; the main transmission cardan shaft is lifted out to complete dismounting of the main transmission cardan shaft; and the new main transmission cardan shaft is hoisted to the installation position through the special hoisting tool, and the new main transmission cardan shaft is reinstalled in place. According to the invention, through the hoisting of the special hoisting tool, the time for matching with a chain block is saved in hoisting and reassembling, and meanwhile, the labor intensity is reduced.
本发明涉及检修技术领域,尤其涉及一种定宽压力机主传动万向轴快速更换方法,该方法包括:制作一专用吊具;拆除主传动万向轴与滑床相连接的法兰螺栓,并使用提升螺栓将主传动万向轴的下十字包向上收缩;利用行车吊起专用吊具,使得专用吊具的上横板位于减速机之上,该专用吊具的下横板的上表面与主传动万向轴的下表面相接触,当吊具受力时停止提升专用吊具,拆除主传动万向轴与减速机输出端连接处的锚固螺栓,并将主传动万向轴吊出以完成主传动万向轴的拆除;利用专用吊具将新主传动万向轴吊至安装位置,并将新主传动万向轴回装到位。本发明通过专用吊具的吊装在吊除与回装上节省使用手拉葫芦相配合的时间,同时减轻了劳动强度。
