The invention discloses a rising-falling micro-motion system of a crane. The key point of the technical scheme is as follows: the rising-falling micro-motion system of the crane comprises a main hoisting motor, wherein an output shaft of the main hoisting motor is connected to a main hoisting reducer through a first coupling, the output end of the main hoisting reducer is connected to a hoisting coiling block, a steel wire rope winds the hoisting coiling block, a brake disc is arranged on one side of the hoisting reducer, a hoisting brake is arranged on the brake disc, and a micro-motion motorwhich drives the main hoisting motor to move is arranged behind the main hoisting motor. When the hoisting mechanism operates at a high speed, a clutch is separated from the main hoisting motor, themain hoisting motor drives the hoisting coiling block to rotate at a high speed, and the hoisting mechanism works normally. In a rising-falling stage, the clutch clings to the main hoisting motor, themain hoisting motor is axis synchronous with the micro-motion reducer, and the micro-motion motor decelerated by the micro-motion reducer drives the main hoisting motor to rotate so as to rise and fall at a relatively low speed. The rising-falling micro-motion system is convenient to lift and align precisely, so that the work efficiency is improved.
本发明公开了一种起重机的起落微动系统,其技术方案的要点是包括有主起升电机,所述主起升电机的输出轴通过第一联轴器连接有主起升减速器,所述主起升减速器输出端连接有起升卷筒,起升卷筒上缠绕有钢丝绳,所述的起升减速器一侧设有制动盘,在制动盘上设有起升制动器,在所述主起升电机的后方设有带动主起升电机运动的微动电机。本发明起升机构高速运行时,离合器与主起升电机分离,主起升电机带动起升卷筒高速转动,起升机构正常工作。起落阶段时,离和器与主起升电机贴合,主起升电机与微动减速器轴同步,微动电机经微动减速器减速后驱动主起升电机转动,以较低的速度起升和下降。便于精准升降和对位,提高工作效率。
