The fixed column type cantilever for the crane comprises a stand column, a swing mechanism is arranged at the top end of the stand column, a cantilever is connected to the top of the swing mechanism, an electric hoist is connected to the bottom of the cantilever through a guide rail, a steel wire rope is wound and unwound on the electric hoist, and the outer portion of the upper end of the stand column is fixedly sleeved with a supporting ring. A rotating ring is movably arranged in the supporting ring, one side of the rotating ring is connected with the rear end of the cantilever through a connecting piece, a supporting frame is arranged on the side, opposite to the connecting piece, of the rotating ring, and a supporting mechanism composed of a supporting cylinder, an ejector rod and an ejector block is arranged on the top of the supporting frame. According to the fixed column type cantilever for the crane, effective auxiliary supporting can be achieved, mechanical fatigue of different degrees occurring in long-term operation is reduced, the strength and rigidity of the cantilever can be guaranteed, and the stability of the whole crane is improved.
本发明公开了一种起重机用定柱式悬臂,包括立柱,所述立柱的顶端设有回转机构,所述回转机构的顶部连接有悬臂,所述悬臂的底部通过导轨连接有电动葫芦,所述电动葫芦上收放有钢丝绳,所述立柱上端的外部固定套设有托环,所述托环的内部活动设有转环,所述转环的一侧通过连接件与悬臂的后端相连接,且所述转环位于连接件相反的一侧设有支撑架,所述支撑架的顶部设有由支撑筒、顶杆和顶块构成的支撑机构。该起重机用定柱式悬臂能够得到有效的辅助支撑,减小在长期作业中出现的不同程度机械疲劳,有利于保证悬臂的强度和刚度,提高整个起重机的稳定性。
