The invention relates to the technical field of cranes, and discloses a fixed column type cantilever crane. The fixed column type cantilever crane comprises a stabilizing column, a hoisting assembly and a lubricating assembly, wherein a carne jib is movably connected to the top end of the stabilizing column, a steel cable is fixedly arranged at the top end of the carne jib, and the bottom end of the carne jib is movably connected with the top end of the hoisting assembly. When rotating wheels rotate to the right side or the left side of a slide way, the outer walls of the rotating wheels can push ejector rods, an outer ring is driven to rotate, first magnetic blocks are driven to rotate around the circle center of an inner ring, and at the moment, the ejector rods push a lifting rod to ascend, then the lifting rod can extrude a telescopic air bag, and air is extruded into an air outlet pipe through a one-way valve; and after the outer ring rotates, the outer ring is influenced by the first magnetic blocks and second magnetic blocks, then the ejector rods are always kept in a regular cross state, the lifting rod is influenced by a weight ball and returns to an initial position, andthe telescopic air bag is influenced by a spring and returns to an initial position, so that the effect of recycling is achieved, and the effect can be achieved only by normally using the rotating wheels.
本发明涉及起重机技术领域,且公开了一种定柱式悬臂起重机,包括稳定柱、起吊组件和润滑组件,所述稳定柱顶端活动连接有吊臂,所述吊臂的顶端固定安装有钢索,所述吊臂的底端与起吊组件的顶端活动连接,在转动轮转动到滑道的右侧或左侧时,可使转动轮的外壁推动顶杆,带动外环转动,带动第一磁块以内环的圆心转动,此时,顶杆推动升降杆上升,以此升降杆可挤压伸缩气囊,从而将气体通过单向阀挤入出气管中,外环转动之后,外环受到第一磁块与第二磁块影响,使顶杆始终保持正十字交叉状态,且升降杆受到重物球的影响,回到初始位置,伸缩气囊受到弹簧影响回到初始位置,达到可循环使用的效果,且只需转动轮正常使用即可达到该效果。
