The invention belongs to the field of engineering machinery, and discloses a winch type hoisting mechanism and a crane. The winch type hoisting mechanism comprises a power motor (1), a gear ratio speed reducer (2) and a winding drum component which are in transmission connection in sequence, wherein the power motor (1) comprises a motor rotating shaft (11), the gear ratio speed reducer (2) comprises a speed reducer output shaft (21), and the reduction ratio of the gear ratio speed reducer (2) is adjustable, so that the speed reducer output shaft (21) can rotate at an adjustable rotating speed lower than the rotating speed of the motor rotating shaft (11). Therefore, the winch of the winch type hoisting mechanism can be increased to the maximum speed, the power motor is prevented from generating larger rotational inertia, the fluctuation phenomenon of the hoisting speed is thoroughly eliminated, the controllability of the mechanism is improved, and the working efficiency of the mechanism is improved.
本发明属于工程机械领域,公开了一种卷扬式起升机构和起重机,所述卷扬式起升机构包括依次传动连接的动力马达(1)、变速比减速机(2)和卷筒组件,所述动力马达(1)包括马达转轴(11),所述变速比减速机(2)包括减速机输出轴(21),所述变速比减速机(2)的减速比可调节设置,使得所述减速机输出轴(21)能够以可调节且低于所述马达转轴(11)的转速转动。由此可见,本发明可实现卷扬式起升机构卷扬最大速度的提升,避免动力马达产生较大的转动惯量,彻底消除起升速度波动现象,提升对机构的操控性,并提高机构工作效率。
