Micro-motion speed regulation walking trolley

The utility model discloses a micro-motion speed regulation walking trolley which comprises a main operation speed reduction motor, a planetary reducer with a brake wheel, a first brake and a micro-motion brake motor. The planetary reducer with the brake wheel is additionally arranged between the main running gear motor and the micro-motion brake motor, the main running gear motor works during normal walking, the first brake is closed when micro-motion is needed, and the second brake of the micro-motion brake motor is opened to work; and the speed ratio is greatly increased, and a very small walking distance can be obtained by switching on and switching off each time, so that the special micro-motion working condition requirement is met, and the use requirement of the special low-clearance crane is met. 本实用新型公开了一种微动调速行走小车，包括主运行减速电机、带制动轮行星减速器、第一制动器和微动制动电机。本实用新型通过采用主运行减速电机和微动制动电机之间加了带制动轮的行星减速器，正常的行走时主运行减速电机工作，需要微动时第一制动器关闭，微动制动电机的第二制动器打开工作，使得此时的运行速比为行星减速器和减速电机减速器速比的乘数，速比大大加大，每一次通断电可以做出非常微小的行走距离，以适应特殊微动工况要求，满足特殊低
