The folding telescopic automobile crane mechanical arm comprises a first telescopic arm, the first telescopic arm is movably connected into a second telescopic arm, the end, away from the second telescopic arm, of the first telescopic arm is fixedly connected with a connecting arm, and two sets of connecting grooves are formed in the lower end of the connecting arm; a first folding arm is movably connected into the connecting groove, the second connecting gear is slidably connected into the connecting cavity, one end of the steel rope sequentially penetrates through the two supporting plates and is fixedly connected with a lifting hook, and the other end of the steel rope sequentially penetrates through the two guiding mechanisms. After the limiting of the first folding arm is cancelled through the limiting mechanism, the first folding arm is driven by the rotation of the transmission gear to rotate, the steel rope rotates in one direction along with the first folding arm through the rotation of the second connecting gear, and meanwhile, the first folding arm can be driven by the transmission gear to rotate to any angle; therefore, the lifting hook is obliquely pulled by a certain angle to lift a heavy object, and the steel rope cannot be separated from the guide wheel.

    本发明公开了一种折叠伸缩式汽车起重机机械臂,包括第一伸缩臂,所述第一伸缩臂活动连接于第二伸缩臂内,所述第一伸缩臂远离第二伸缩臂一端固定连接有连接臂,所述连接臂下端内开设有两组连接槽,所述连接槽内活动连接有第一折叠臂,所述第二连接齿轮滑接于连接腔内,所述钢绳一端依次穿过两组支撑板,并固定连接有吊钩,所述钢绳另一端依次穿过两组导向机构;通过限位机构在取消了对第一折叠臂的限位后,在传动齿轮的转动带动下使第一折叠臂进行转动,通过第二连接齿轮的转动使钢绳跟随第一折叠臂向一个方向转动,同时通过传动齿轮的带动可使第一折叠臂转动至任意的角度,以满足吊钩被斜拉一定角度起吊重物,而不会使钢绳脱离导向轮。
