The invention belongs to the technical field of hoisting mechanisms, and particularly relates to a hoisting mechanism for a crane, which comprises a trolley frame and a winding drum unit, the winding drum unit comprises a winding drum A and a winding drum B, winding grooves are uniformly formed in the outer walls of the winding drum A and the winding drum B, and limiting units are arranged above the winding drum A and the winding drum B; telescopic guide cylinders are fixedly connected to the left side and the right side of the middle of the lower surface of the trolley frame, a lifting seat is fixedly connected to the other ends of the telescopic guide cylinders, a supporting frame is fixedly connected to the lower portion of the right side face of the lifting seat, a motor is installed on the left side face of the supporting frame, and a screw rod is fixedly connected to an output shaft of the motor and comprises a screw rod A section and a screw rod B section which are opposite in thread direction. The outer sides of the screw A section and the screw B section are fixedly connected with a lifting hook A and a lifting hook B through the lower surfaces of a screw block A and a screw block B. A speed detector is installed on the left side face of the lifting base. The lifting device is suitable for lifting heavy objects with different lengths, the phenomenon that the steel wire rope swings or jumps out of a groove is avoided, lifting is stable, the lifting speed is monitored, and safety is high.

    本发明属于起升机构技术领域,具体涉及一种起重机用起升机构,包括小车架和卷筒单元,卷筒单元包括卷筒A和卷筒B,卷筒A和卷筒B的外壁上均匀设置有绕线槽,卷筒A和卷筒B的上方均设置有限位单元,小车架下表面中部的左右两侧均固连有可伸缩导向筒,可伸缩导向筒另一端固连有起升座,起升座右侧面下部固连有支撑架,支撑架左侧面安装有电机,电机的输出轴固连有螺杆,螺杆包括螺纹方向相反的螺杆A段和螺杆B段,螺杆A段和螺杆B段的外侧分别通过螺块A和螺块B的下表面分别固连有吊钩A和吊钩B,起升座左侧面安装有速度检测仪;本发明适用于起吊不同长度的重物,避免钢丝绳出现摇摆或跳槽现象,起吊平稳,对起吊速度进行监控,安全性高。
