The invention relates to the technical field of cranes, in particular to an anti-falling crane. The anti-falling crane comprises a fixing base, a fixing plate, a fixing shaft, supporting rods and a cleaning brush; a fixing supporting column is mounted on the fixing base through bolts; a suspension arm body is rotationally connected to the top end of the fixing supporting column; a hydraulic part is rotationally connected to the suspension arm body; the bottom end of the hydraulic part is rotationally connected to the fixing supporting column; a threaded positioning strip is welded and fixed to the suspension arm body; and the fixing plate is rotationally connected to the threaded positioning strip. The anti-falling crane has the beneficial effects that the anti-falling crane is improved on the basis of an existing anti-falling crane; the supporting rods can be pushed to move downwards through rotation of two-way threaded rods and combination of mounting rods and fixing wheels; and at the moment, the supporting rods can drive a rotating shaft to rotate stably by combining with a guide rod and a guide groove, and can automatically rotate and clean the supporting position by combining with a rotating disc and the cleaning brush, so that unstable supporting caused by excessive impurities in the supporting position can be prevented.

    本发明涉及吊机技术领域,具体为一种防坠落吊机。一种防坠落吊机,包括固定底座、固定板、固定轴、支撑杆和清扫刷,所述固定底座上螺栓安装有固定撑柱,固定撑柱的顶端转动连接有吊臂本体,所述吊臂本体上转动连接有液压部件,液压部件的底端转动连接在固定撑柱上,所述吊臂本体上焊接固定有螺纹定位条,螺纹定位条上转动连接有固定板,本发明的有益效果是:该防坠落吊机,在现有的基础上进行改进,利用双向螺纹杆的转动,结合安装杆和固定轮能够推动支撑杆向下运动,此时支撑杆结合导向杆和导向槽能够带动转动轴稳定转动,结合转动盘和清扫刷能够将支撑位置进行自动转动清扫工作,进而能够防止支撑位置存在过多杂质导致支撑不平稳。
