The invention discloses a transmission device for feeding of a lifting cage of a construction hoist. The transmission device comprises a bottom plate; a groove is formed in the upper portion of the bottom plate; rotating discs are arranged on the inner walls of the two sides of the groove, and movably connected with the inner walls of the groove; one of the rotating discs is connected with a driving device; one side of each rotating disc is fixedly provided with a transmission rod; the transmission rods are parallel to the tangent lines of the rotating discs; straight rods are movably connected to the two ends of the transmission rods; a folding rod is movably connected to the other end of each straight rod; a first fixing rod is arranged on a joint in the middle of each folding rod; and the two ends of the first fixing rods penetrate through the folding rods and extend out to be fixedly connected with the inner walls of the groove. The transmission rods and the straight rods are driven to move synchronously through rotation of a servo motor, the folding rods can rotate by a larger margin through the limiting effect of the first fixing rods, and the whole transmission system is simple, efficient, stable and reliable.

    本发明公开了一种施工升降机吊笼上料用传动装置,包括底板,底板的上方设有凹槽,凹槽的两侧内壁上均设有转盘,转盘与凹槽的内壁呈活动连接,并且其中一个转盘连接有驱动装置,转盘的一侧固定安装有传动杆,传动杆与转盘的切线相平行,并且传动杆的两端均活动连接有直杆,直杆的另一端活动连接有折杆,折杆中间的一个节点设有第一固定杆,第一固定杆的两端贯穿折杆并延伸出去与凹槽的内壁固定相连;本发明通过伺服电机的转动来带动传动杆和直杆同步运动,再通过第一固定杆的限制作用,使得折杆可以更大幅度的转动,整个传动系统简洁高效且稳定可靠。
