The invention discloses a jacking system of a self-stabilizing chain block. Tenons are arranged at one ends of the first chain blocks, corresponding mortises are formed in the other ends of the first chain blocks, every two adjacent first chain blocks are connected through a pin shaft, first annular bosses are arranged at the bottoms of the first chain blocks, and first annular grooves corresponding to the first annular bosses are formed in the tops of the first chain blocks; the top and the bottom of the first chain block are both first spiral rising surfaces; the side, away from the foundation, of the first guide frame is a second spiral rising face, and a first groove is formed in the second spiral rising face. The first driving piece is arranged in the first guide frame; and when the jacking system is jacked, the first driving piece drives each first chain block to move along the first groove of the second spiral rising surface, so that the tenon of the first chain block is inserted into the mortise of the adjacent first chain block. Therefore, according to the jacking system for stabilizing the chain blocks, the lateral bending resistance is improved due to the fact that the closed annular structures which are mutually tenoned are defined, and meanwhile the first chain blocks are convenient to store and compact in structure.
本申请公开了一种自稳定链块的顶升系统。多个第一链块的一端均设置有榫头,其另一端均设置有相对应卯孔,相邻两个第一链块通过销轴连接,多个第一链块的底部均设置有第一环形凸台,且其顶部均设置有与第一环形凸台对应的第一环形凹槽,第一链块的顶部和底部均为第一螺旋上升面;第一导向架远离基础的一侧为第二螺旋上升面,第二螺旋上升面设置有第一凹槽;第一驱动件设置于第一导向架内;当顶升系统顶升时,第一驱动件驱动每个第一链块沿第二螺旋上升面的第一凹槽移动,使第一链块的榫头插入相邻第一链块的卯孔内。因此,本申请稳定链块的顶升系统因为围合成相互榫合的闭合环状结构提升了侧向抗弯能力,同时,第一链块便于收纳,结构紧凑。
