The invention discloses a building construction safety elevator. The building construction safety elevator comprises a gear and a rack matched with the gear in a meshed mode and further comprises a driving buffer chain combination, the driving buffer chain combination comprises a parallel hinge four-rod mechanism, main chain wheels, a chain and a spring damping rod, the spring damping rod is located in the parallel hinge four-rod mechanism and is vertically distributed, and the two ends of the spring damping rod are correspondingly and rotatably connected with two opposite hinge shafts on theparallel hinge four-rod mechanism. According to the building construction safety elevator, the parallel hinge four-rod mechanism is arranged, the main chain wheels are connected to the four hinge shafts of the parallel hinge four-rod mechanism, the chain is engaged with the four main chain wheels, the lowest main chain wheel is connected with the gear, specifically, a reinforcing shaft is arrangedon one side of the main chain wheel, one end of the reinforcing shaft is fixedly connected with one side of teeth on the gear, when lifting is conducted, loads borne by the teeth on the gear are mainly borne by the main chain wheels, and therefore the phenomenon of tooth breaking can be avoided.
本发明公开了一种建筑施工安全升降机,包括齿轮和与齿轮啮合配合的齿条,还包括驱动缓冲链组合,所述驱动缓冲链组合包括平行铰链四杆机构、主链轮、链条和弹簧减震杆,所述弹簧减震杆位于平行铰链四杆机构内且为竖直分布,该弹簧减震杆的两端对应和平行铰链四杆机构上两个相对的铰接轴转动连接。本发明中,设置平行铰链四杆机构,平行铰链四杆机构的四个铰接轴上连接主链轮,四个主链轮上咬合一个链条,位于最下部的一个主链轮和齿轮连接,具体是此主链轮的一侧设置加强轴,加强轴的一端和齿轮上齿牙的一侧固定连接,升降时,齿轮上齿牙所承受的负载主要由主链轮来承担,进而可以避免出现断齿的现象。
