The invention discloses a multifunctional lifting device for an unmanned crane. The multifunctional lifting device comprises a base and a rotary disc; the position, close to the center position, of the top surface of the base is provided with the rotary disc, and the top of the rotary disc is fixedly provided with a supporting frame; the top of the supporting frame is provided with a supporting arm; when the height of an object does not reach the moving condition, a second hydraulic rod in a second hydraulic cylinder is controlled to move towards the outer side, thus, the clamping height of the object is further increased, the object moving height is reached, the object is avoided making contact with an object on the ground, and movable transferring work of the object in different directions is facilitated; the top of an installation seat is provided with a clamping plate, the clamping plate is provided with a through hole, and an insert rod penetrates through the interior of the through hole; the appearance outline of the clamping plate and the interior outline of a clamping groove are the same, so that when the clamping plate at the top of the installation seat is inserted into the clamping groove, the insert rod is inserted into the through hole formed in the clamping plate conveniently, installing work of the installation seat is facilitated, and a special gripper is convenient to replace; and the working efficiency is improved, and the time for maintaining and replacing a traditional gripper is greatly shortened.

    本发明公开了一种无人起重机上用的多功能起吊装置,包括底座和转盘,所述底座的顶面靠近中心位置设置有转盘,转盘的顶部固定设置有支撑架,支撑架的顶部设置有支撑臂,当物件的高度达不到移动条件时,控制第二液压缸内部的第二液压杆向外侧移动,使得物件的夹取高度进一步升高,达到物件移动高度,避免触碰到地面物件,便于进行物件不同方位的移动搬运工作,安装座的顶部设置有卡板,卡板上开设有通孔,插杆贯穿该通孔的内部,卡板的外形轮廓与卡槽的内部轮廓相同,使得安装座顶部的卡板插入卡槽的内部时,便于插杆插入卡板上通孔的内部,便于安装座的安装工作,便于更换专用抓手,提高工作效率,大大降低传统抓手维修更换时间。
