The invention provides a constructional engineering crane. The constructional engineering crane structurally comprises a hanging bracket, an auxiliary supporting frame, a rotator, a stand column, a bottom plate and a lifting device, wherein the lifting device is movably mounted on the hanging bracket; the upper end of the connecting hanging bracket is welded to the lower end of the auxiliary supporting frame; the right side of the hanging bracket and the right side of the auxiliary supporting frame are welded to the rotator; and the right side of the rotator is welded to the left side of the stand column. Through arrangement of the rotator, when the bending degree is too large, a connecting column pushes a guide needle to pierce a rubber ring under the action of a guide connecting rod, gas between an inner ring sleeve and the rubber ring enters a slim hole through a gas inlet guide hole and then is discharged into a gas guide groove frame from the slim hole, a sealing ring can be slowly recovered, the gas pressure in the gas guide groove frame is increased after the gas enters the gas guide groove frame, and a warning rod is pushed to move out of an outer cover, so that the warning effect can be effectively achieved, and whether a rotating rod column is bent or not can be better observed.

    本发明提供一种建筑工程吊机,其结构包括吊架、辅助支撑架、旋转器、立柱、底板、起吊器,起吊器安装于吊架上且活动,连接吊架上端与辅助支撑架下端相焊接,吊架、辅助支撑架右侧与旋转器相焊接,旋转器右侧与立柱左侧相焊接,本发明通过设置旋转器,当折弯程度过大时,在导接杆的作用下连接柱将会推动导针刺穿橡胶环,从而将会致使内环套与橡胶环之间的气体通过进气导孔进入到细孔内,然后在从细孔排向导气槽架内部,且封环将会缓慢的复原,且气体进入到导气槽架内部后,导气槽架内部的气压将会增大,从而将会推动警示杆往外移动,将警示杆推出外罩,从而就能够有效的起到警示的作用,且也能够更好的观察转杆柱是否发生弯折。
