The invention belongs to the field of lifting devices, and discloses a jacking mechanism and a truss arm assembly line. The jacking mechanism comprises a fixing frame and a jacking mechanism, the jacking frame and the fixing frame are arranged up and down at an interval; the first double-rod folding mechanism and the second double-rod folding mechanism define a first included angle and a second included angle respectively, the first included angle and the second included angle are arranged in a reverse opening mode in the transverse direction, and the upper end and the lower end of the first double-rod folding mechanism and the upper end and the lower end of the second double-rod folding mechanism are hinged to the jacking frame and the fixing frame respectively; and the cam driving mechanism can drive the first double-rod folding mechanism and the second double-rod folding mechanism to synchronously displace, so that the jacking frame gradually rises in the process that the first included angle and the second included angle are synchronously increased. The method can solve the problem that the manufactured truss arm section cannot be timely separated from the supporting table in the assembly line production process of the truss arm, so that the assembly line is prevented from stopping and waiting for production, and the sliding and falling risk of the truss arm section can be reduced.
本发明属于升降装置领域,公开了一种顶升机构和桁架臂流水线。其中,顶升机构包括:固定架;顶升架,该顶升架和固定架上下间隔设置;第一双杆折叠机构和第二双杆折叠机构,分别限定出第一夹角和第二夹角,第一夹角和第二夹角沿横向反向开口设置,第一双杆折叠机构的上下两端和第二双杆折叠机构的上下两端均分别铰接于顶升架和所述固定架;和凸轮驱动机构,能够驱动第一双杆折叠机构和第二双杆折叠机构同步位移,以使得顶升架在第一夹角和第二夹角同步增大的过程中逐渐升高。本发明可解决在桁架臂流水线生产过程中完制的桁架臂节无法及时脱离支撑台的问题,以免流水线停线待产,还能降低桁架臂节滑坠风险。
