The invention discloses a rotary fixing device for a gantry crane. The rotary fixing device comprises a fixed mounting seat fixed on a first transport flatcar; the lifting seat is used for fixedly mounting the gantry crane and can lift relative to the fixed mounting seat, so that the gantry crane can go up and down the first transport flatcar; the pivotal bearing is arranged between the fixed mounting seat and the lifting seat, and the lifting seat can horizontally rotate relative to the fixed mounting seat through the pivotal bearing so as to adjust the mounting direction of the gantry crane. And when the gantry crane is in a transportation working condition, the gantry crane is longitudinally locked and mounted in the groove of the fixed mounting seat. And after the gantry crane arrives at the operation site, the locking mechanism is released, and the gantry crane is separated from the groove, so that the operation deployment of the gantry crane is realized. The gantry crane fixing device can solve the technical problems of fixing the gantry crane during transportation and deploying the gantry crane before operation.
本发明公开了一种龙门吊旋转固定装置,包括:固定于第一运输平车上的固定安装座;用于固定安装龙门吊的升降座,升降座能相对于固定安装座进行升降运动,以实现龙门吊上下第一运输平车;设置于固定安装座与升降座之间的回转轴承,通过回转轴承使得升降座能相对于固定安装座进行水平旋转运动,以调整龙门吊的安装方向。当处于运输工况时,龙门吊被纵向锁定安装于固定安装座的凹槽中。当到达作业现场后,锁紧机构释放,龙门吊从凹槽中脱出,以实现龙门吊的作业部署。本发明能解决龙门吊在运输时的固定,以及在作业前对龙门吊进行部署的技术问题。
