The invention relates to the field of folding arm cranes, and discloses a folding type suspension arm which comprises a supporting plate, and a suspension arm mechanism is fixedly mounted at the top of the supporting plate. According to the device, a second motor operates to drive a second threaded rod to rotate so as to drive a second supporting arm to slide on the side face of the inner wall of a first supporting arm, sliding of the second supporting arm enables a gear to rotate on the side face of a first rack, and rotation of the gear enables a second rack to move so as to drive a third supporting arm to move; through the arrangement of the structure, the suspension arm can be effectively folded, limitation is reduced, the situation that the suspension arm cannot be effectively used due to large occupied space is prevented, and therefore the problem that the suspension arm cannot be effectively used due to the fact that a certain height exists in lifted goods in the using process of the cantilever lifting device with the folding arm is solved. The problem that the suspension arm is inconvenient to fold when not in use due to the fact that the suspension arm occupies a certain space, and certain limitation is caused is solved.
本发明涉及折叠臂吊领域,公开了一种折叠式吊臂,包括支撑板,所述支撑板的顶部固定安装有吊臂机构。本发明中,通过第二电机的运作带动第二螺纹杆转动从而带动第二支撑臂在第一支撑臂内壁的侧面滑动,通过第二支撑臂的滑动使齿轮在第一齿条侧面转动,通过齿轮的转动使第二齿条位移从而带动第三支撑臂进行位移,实现第二支撑臂与第三支撑臂地伸出,该结构的设置,能够有效地使吊臂能够进行收起减少局限性,防止空间占用较大而得不到有效的使用,从而达到解决了该折叠臂的悬臂吊装置在使用过程中时由于起吊货物存在一定的高度,占用一定的空间,因此在不使用状态下,不方便对吊臂进行折叠,使得具有一定的局限性问题。
