The invention discloses a crane hoisting mechanism, and relates to the technical field of hoisting mechanical equipment. The crane hoisting mechanism comprises a frame, a first winding drum, a secondwinding drum, a mooring rope, a first driving device, a second driving device, a chain, a wheel set and two chain wheels, the wheel set is mounted at the bottom of the frame, the first driving deviceis used for driving the wheel set to move, the first winding drum and the second winding drum are rotationally installed on the frame, one end of the first winding drum and one end of the second winding drum are each provided with the chain wheels, the chain is installed on the two chain wheels, the second driving device is used for driving the first winding drum and the second winding drum to rotate, and the diameter of the first winding drum is larger than that of the second winding drum, the cable is wound on the first winding drum and the second winding drum, and when the second winding drum unwinds the cable, the first winding drum winds the cable upwards, and when the second winding drum winds the cable upwards, the first winding drum unwinds the cable. According to the crane hoisting mechanism, cargos are driven to lift at a differential speed and are strictly limited, and the transmission lifting is stable, safe and reliable.

    本发明公开一种起重机起升机构,涉及起重机械设备技术领域,包括车架、第一卷筒、第二卷筒、缆绳、第一驱动装置、第二驱动装置、链条、车轮组和两个链轮,车轮组安装于车架底部,第一驱动装置用于驱动车轮组运动,第一卷筒和第二卷筒分别转动安装于车架上,第一卷筒的一端和第二卷筒的一端分别安装有一个链轮,链条安装于两个链轮上,第二驱动装置用于驱动第一卷筒和第二卷筒转动,第一卷筒的直径大于第二卷筒的直径,缆绳缠绕于第一卷筒和第二卷筒上,第二卷筒下放缆绳时第一卷筒向上缠绕缆绳,第二卷筒向上缠绕缆绳时第一卷筒下放缆绳。本发明提供的起重机起升机构,采用差速驱动货物升降,严格限位,传动升降平稳,安全可靠。
