Abstract

A compact-type built-in differential velocity regulating winch which is a winch can solve the problems that existing winch velocity regulating systems are complex and mechanical transmission requireslarge space. An electromotor is used for driving a high-speed level gear sleeve, a high-speed level sun gear and a high-speed level planet gear so as to lead a high-speed level gear holder to rotate.A transmission shaft is used for leading a low-speed level sun gear to rotate. A low-speed level planet gear is used for leading a low-speed level gear ring to rotate. A low-speed level gear holder and a roller device do not rotate. During the normal operation of the electromotor, a pressure regulating valve is manually braked; two braking springs cause a braking block to brake a braking plate; simultaneously, a velocity pressure regulating valve is manually operated; a velocity regulating spring causes a velocity regulating brake block to brake a velocity regulating plate; the low-speed levelgear ring fixedly connected with the velocity regulating plate stops rotation; the low-speed level planet gear drives the low-speed level gear holder to rotate; the roller rotates accordingly; therefore, the work of weight lifting is finished. The compact-type built-in differential velocity regulating winch has compact structure, occupies a small area and does not need large space. Simultaneously, the velocity regulation is realized by means of hydraulic regulation, and the integral structure is simple.
