The invention belongs to the technical field of gantry cranes, and particularly relates to a movable gantry crane which comprises a transverse top plate and vertical supporting rods, the vertical supporting rods are arranged in pairs, an upper limit height adjusting assembly is arranged at the upper end of each vertical supporting rod, and the two ends of the transverse top plate are connected with the two upper limit height adjusting assemblies. A sliding control assembly is arranged at the lower end of each vertical supporting rod, a rotating plate is rotationally connected to each sliding control assembly, and a rotating control assembly is arranged on each rotating plate; on the premise that mobility is guaranteed, along with electrification of a coil and movement of an inserting rod and a sliding control rod, absolute stability of the device is guaranteed, deviation is avoided during operation, safety is guaranteed, meanwhile, in the process that two vertical supporting rods get close, an auxiliary transverse plate in the horizontal state gradually rotates, a transverse top plate is pushed upwards, and therefore the stability of the device is improved. And the hoisting upper limit of the device is increased.
本发明属于龙门吊技术领域,具体是指一种可移动式龙门吊,包括横向顶板和竖向支撑杆,所述竖向支撑杆成对设置,每个所述竖向支撑杆的上端上设有上限调高组件,所述横向顶板的两端与两个上限调高组件相连,每个所述竖向支撑杆的下端上设有滑动控制组件,所述滑动控制组件上转动连接有转动板,所述转动板上设有转动控制组件;本发明在保证可移动性的前提下,随着线圈的通电,插杆和滑动控制杆的运动,保证了本装置的绝对稳定性能,不会在运转时发生偏移,保证了安全性,同时通过两竖向支撑杆靠近的过程中,水平状态的辅助横板逐渐转动,将横向顶板向上推高,增加了本装置的起吊上限。
