The combined type electric single-beam crane comprises two end beams, first sliding grooves are formed in the tops of the two end beams, second sliding grooves are formed in the left sides and the right sides of the first sliding grooves in the end beams, sliding blocks are arranged on the inner sides of the two end beams, and rectangular openings are formed in the sliding blocks; a cross beam is arranged in the rectangular opening, protective sleeves are fixedly welded to the left end and the right end of the cross beam, connecting columns are slidably connected into the protective sleeves, and a first motor is fixedly welded into the cavity. A chain of an electric hoist and a connecting plate are fixed through four telescopic rods, shaking occurs during surface hoisting and moving, meanwhile, multiple fixing is conducted through four hooks, potential safety hazards are reduced, the service life is prolonged, meanwhile, a first motor, a protective sleeve, a threaded rod, connecting columns and a cross beam are used in cooperation, the distance between the connecting columns can be adjusted, and the safety of the electric hoist is improved. Errors caused by measurement errors during installation are avoided, and the device has the advantages of being high in safety and convenient to install.

    本发明公开了一种组合式电动单梁起重机,包括两个端梁,两个所述端梁顶部均开设有第一滑槽,所述端梁上第一滑槽的左右两侧均开设有第二滑槽,两个所述端梁的内侧设置有滑动块,所述滑动块上开设有矩形口,所述矩形口内设置有横梁,所述横梁的左右两端均焊接固定有保护套,所述保护套内滑动连接有连接柱,所述空腔内焊接固定有第一电机。本发明通过四个伸缩杆将电动葫芦的链条与连接板进行固定,表面起吊与移动时,发生晃动,同时通过四个挂钩进行多重固定,减小安全隐患,延长使用寿命,同时第一电机、保护套、螺杆、连接柱与横梁配合使用,可调节连接柱之间的距离,避免安装时因测量误差引起的失误,具有安全性高、便于安装的优点。
