The invention discloses a self-loading-unloading type auxiliary arm mounting mechanism of an automobile crane. The self-loading-unloading type auxiliary arm mounting mechanism comprises a main arm andan auxiliary arm rod, wherein a butt joint seat is arranged on the main arm and is close to one end of the main arm, a bearing arm is rotationally connected between a transfer disc and a sliding sleeve, a frame plate is fixedly connected to the upper end of the main arm, a pull rod is rotationally connected between two sets of sliding connection blocks and a sliding connection plate body, the outer end of a shaft rod is fixedly connected with a driven fluted disc meshed with a worm, and the outer ends of a first gear and a second gear are fixedly connected with supporting arms. According to the self-loading-unloading type auxiliary arm mounting mechanism, firstly, the auxiliary arm rod is tensioned and fixed through the bearing arm, so that stable bridging between the auxiliary arm rod and the main arm is guaranteed when the auxiliary arm rod is used for lifting a heavy object; secondly, the auxiliary arm rod is tensioned and fixed through the bearing arm, so that stable bridging between the auxiliary arm rod and the main arm is guaranteed when the auxiliary arm rod is used for lifting the heavy object; and finally, a limiting block extends outwards, the sliding range of the sliding connection blocks is limited, and then it is ensured that the bearing arm always keeps a stable tensioning state on the auxiliary arm rod.
本发明公开了一种汽车起重机自装卸式副臂安装机构,包括主臂和副臂杆,所述主臂靠近主臂的一端安装有对接座,所述转接盘和滑套之间转动连接有承重臂,所述主臂的上端固定连接有架板,两组所述滑接块与滑接板体之间转动连接有拉杆,所述轴杆的外端固定连接有与蜗杆相啮合的从动齿盘,所述第一齿轮和第二齿轮的外端均固定连接有支臂。本发明中,首先,通过承重臂对副臂杆的拉紧固定,保障副臂杆在起重重物时保持和主臂之间的稳定架接,其次,通过承重臂对副臂杆的拉紧固定,保障副臂杆在起重重物时保持和主臂之间的稳定架接,最后,限位块向外侧伸出,对滑接块的滑动范围进行限定,进而保障承重臂始终对副臂杆保持稳定的拉紧状态。
