The invention provides a safe rotary building crane. The safe rotary building crane structurally comprises a rotator, a stand column, a control box, a supporting seat structure, a winder, a slider anda cross rod, wherein the control box is mounted on the stand column, and the stand column is embedded in the supporting seat structure. According to the safe rotary building crane, an elastic deviceis arranged, a reset spring starts to reset, so that a piston block is pushed to push upwards along an oil cavity, the oil pushes a small piston disc to move leftwards along a cylinder body, a pushingsleeve is driven by the small piston disc to move leftwards through a telescopic rod, so that the pushing sleeve pushes a connecting ring to tilt leftwards, and the stand column is driven by the connecting ring to tilt towards the direction of a buffer along with the stand column, so that the stand column is toppled towards a specified direction, the stand column is effectively prevented from injuring workers in the field after toppling, and unnecessary potential safety hazards caused by random rolling of the stand column after toppling are avoided by arranging a barb structure.
本发明提供一种安全型旋转式建筑吊机,其结构包括旋转器、立柱、控制盒、支撑座结构、卷线器、滑动器、横杆,控制盒安装于立柱上,立柱嵌入于支撑座结构上,本发明通过设置弹力器,复位弹簧将会开始复位,从而推动活塞块沿着油腔向上推动,使得油液推动小活塞盘沿着筒体向左进行移动,在小活塞盘的带动下将会通过伸缩杆带动推压套也向左进行移动,以此使推压套推动连接环向左倾倒,通过连接环带动立柱随其向一起向缓冲器方向倾倒,从而使立柱向指定的方向进行倾倒,有效的避免立柱在倾倒后,砸伤在场的工作人员,通过设置倒钩结构,避免立柱在倾倒后,在随意的滚动,造成不必要的安全隐患的存在。
