The invention belongs to an automatic elevator provided with multi-section combined gantry crane supporting legs, and aims to solve the problems that in an installation process, an occupied area of a construction site is large, the number of hoisting devices is large, the stroke is long, space limitation is caused, and at present, no special automatic elevating equipment exists. According to the scheme points, a shaft of an electric push rod is ejected out and clamped in a clamping groove of an elevating column to jack up an elevating frame in a stepping mode, the elevating frame moves along the elevating column through limitation of a guide wheel, the electric push rod releases a pull ring and is connected with the shaft of the electric push rod by means of a pull rope to move the shaft out of the clamping groove of the elevating column, when the shaft of the electric push rod is completely ejected out, a position of the elevating frame is locked by means of a safety limiting block, a recovery winch is connected with the elevating frame by means of a steel wire rope and a steel wire rope guide wheel, a safety limiting block pull ring is connected with the safety limiting block by means of the pull rope to achieve unlocking, gantry crane supporting leg connecting pieces are arranged on the side face of the elevating frame and used for hoisting all the sections of gantry crane supporting legs on a gantry crane beam, and the automatic elevator is suitable for installation of the multi-section combined gantry crane supporting legs.

    本发明属于一种安装多节组合式龙门吊支腿的自动升降机。所要解决的问题是:安装过程需要施工场地占地面积大,起吊设备多,行程长,受到空间限制;目前尚无专门自动升降设备。所采用方案要点是:电动推杆的轴顶出卡在升降柱的卡槽内将升降框步进顶起,通过导向轮的限制沿升降柱运动,电动推杆释放拉环通过拉绳连接电动推杆的轴将其移出升降柱的卡槽,电动推杆轴完全顶出时通过安全限位块将升降框位置锁定,回收绞盘通过钢丝绳和钢丝绳导轮连接升降框,安全限制块拉环通过拉绳连接安全限位块实现解锁,升降框侧面设置龙门吊支腿连接件用来吊装龙门吊梁上的各节龙门吊支腿。适用于多节组合式龙门吊支腿的安装。
