Abstract
The utility model discloses a winch for a ship unloader. The winch for the ship unloader comprises a main motor and a winding drum. An output shaft of the main motor is provided with a high speed shaft brake, and the output shaft of the main motor is in transmission connection with a speed reducer. An output shaft of the speed reducer is provided with a first clutch, the output shaft of the speed reducer is in transmission connection with one end of the winding drum, and the other end of the winding drum is in transmission connection with a standby gear motor. The standby gear motor and the main motor are both electrically connected with a controller. An output shaft of the standby gear motor is provided with a second clutch. The winding drum is provided with a winding drum brake, and the winding drum brake is controlled by the controller. The output shaft of the main motor is provided with a speed sensor, and the speed sensor is electrically connected with the controller. According to the winch for the ship unloader, the standby gear motor is additionally arranged, when the main motor breaks down, normal operation can still be guaranteed, due to the arrangement of the high speed shaft brake and the winding drum brake, safety performance is effectively improved, and the winch for the ship unloader is simple in structure and easy to implement.
