The invention discloses a heavy-object lifting system based on gears and a crank rocker. The system comprises a belt gear transmission unit and a crank rocker transmission unit, wherein the belt geartransmission unit comprises a driving pulley, a belt, a driven pulley, a first bearing base, a second bearing base, a third bearing base, a fourth bearing base, a first gear shaft, a first gear, a second gear and a second gear shaft; and the crank rocker transmission unit comprises a third gear, a first connecting rod, a second connecting rod, a fifth bearing base, a sixth bearing base and a loadgear shaft. A transmission part is driven by the belt, and the belt slips in an overload state, so that an overload protection effect is achieved; and through the gears, the heavy-object lifting system based on the gears and the crank rocker is simple in structure, and relevant components such as the gears can be matched with appropriate models so as to adapt to different lifting fields. The wholestructure is stable, maintenance and management are easy, and transmission efficiency is high.

    一种基于齿轮曲柄摇杆的重物起升系统,包括:皮带齿轮传动单元,包括:驱动皮带轮、皮带、从动皮带轮、轴承底座一、轴承底座二、轴承底座三、轴承底座四、齿轮轴一、齿轮一、齿轮二、齿轮轴二;曲柄摇杆传动单元,包括:齿轮三、连杆一、连杆二、轴承底座五、轴承底座六、负载齿轮轴。传动部分用皮带驱动,在过载状态下,皮带发生打滑,起到过载保护的作用;通过齿轮,基于齿轮曲柄摇杆的重物起升系统,结构简单,相关构件如齿轮等可以选配合适的型号,以适配不同的起升领域。整体结构稳定,易于维修管理,传动效率高。
