The invention belongs to the field of nuclear power overhaul tool equipment, and particularly relates to a lifting crane. The lifting crane comprises an underbed structure which comprises a chassis mechanism, a steering mechanism and a wheel mechanism; a crane jib structure which comprises a crane jib mechanism and a driving mechanism, wherein the crane jib mechanism comprises a vertical jib with one end connected with the steering mechanism, a telescopic jib connected with the other end of the vertical jib and a supporting jib connected with the vertical jib, a target object is hung at the free end of the telescopic jib, and the driving mechanism is arranged on the supporting jib; and a balance weight structure which comprises a balance weight mechanism and an adjusting mechanism used for adjusting the position of the balance weight mechanism in the first direction and/or the second direction, and the first direction and the second direction are arranged in a staggered mode. According to the lifting crane, the supporting jib and the telescopic jib are arranged on the two sides of the vertical jib correspondingly, and a dredging pump and the driving mechanism are arranged on the telescopic jib and the supporting jib correspondingly, so that the vertical jib can keep three-force balance; and the positions of the balance weight mechanism in the first direction and the second direction can be adjusted through the adjusting mechanism, so that the vertical jib is kept balanced.
本发明属于核电检修工装设备领域,尤其涉及一种升降吊车。升降吊车包括:底架结构,包括底盘机构、转向机构以及车轮机构。吊臂结构包括吊臂机构以及驱动机构,吊臂机构包括一端连接转向机构的立臂、连接立臂另一端的伸缩臂以及连接立臂的支撑臂,伸缩臂的自由端吊挂有目标物,驱动机构设置于支撑臂。配重结构包括配重机构以及用于调节配重机构沿第一方向和/或第二方向位置的调节机构,第一方向与第二方向交错设置。本发明通过将支撑臂和伸缩臂分别设置于立臂的两侧,且清淤泵和驱动机构分别设置于伸缩臂和支撑臂,这样有利于使立臂保持三力平衡。再通过调节机构可以调节配重机构于第一方向上和第二方向上的位置,从而使立臂保持平衡。
