The invention discloses a stable lifting cantilever crane stand column. The stable lifting cantilever crane stand column comprises a base, fixed plates are fixedly mounted on the four corners of the base, stable movable plates are fixedly mounted in the fixed plates, fixing mechanisms are mounted at one ends of the stable movable plates, each fixing mechanism comprises a fastening screw, a first thread hole, a buffer spring, a fixed block, a limiting cap, an anti-sliding damping gasket, a sliding rod, a limiting plate and a fixed groove, through elastic buffer effects of the buffer springs, vibration of a lifting motor during work can be effectively reduced, use stability of a crane can be improved, handles on the top ends of the fastening screws are rotated to enable the anti-sliding damping gaskets to be stabilized on the ground, a worker can conveniently carry out operation use, work efficiency of the user can be improved, meanwhile, the limiting plates are mounted and placed on thelower surfaces of the fixed blocks through bolts, mounting, fixing, dismounting, maintaining and replacing of the buffer springs and the anti-sliding damping gaskets are facilitated, and the maintaining efficiency of the worker can be improved.
本发明公开了一种稳定型可升降的悬臂起重机立柱,包括底座,所述底座的四角位置处均安装固定有固定板,所述固定板的内部安装固定有稳固活动板,所述稳固活动板的一端设置有固定机构,所述固定机构包括紧固丝杆、第一螺纹孔、缓冲弹簧、固定块、限位帽、防滑减震垫片、滑动杆、限位板和固定槽;该发明通过缓冲弹簧的弹性缓冲效果,有效降低升降电机在工作时产生的震动,挺高了起重机使用的稳定性,且通过旋转紧固丝杆顶端的手柄使防滑减震垫片稳固的在地面,方便工人操作使用并提高工人的工作效率,同时限位板通过螺栓安装放置在固定块的下表面,方便缓冲弹簧和防滑减震垫片安装固定和拆卸维修更换,增加工人的维修效率。
