Abstract:
1. An electric capstan comprising: an air pump; a motor; a reduction gear; a winching roller; an engagement-disengagement handle; a transmission mechanism; and a speed change mechanism, wherein an input shaft of the air pump is connected to or disconnected from a first output shaft of the motor by the engagement-disengagement handle, and wherein the motor comprises a second output shaft that is connected to the winching roller, and wherein the transmission mechanism comprises a bracket, a first gear, a second gear and a third gear, the bracket is connected to the housing of the motor, the first output shaft of the motor extends into the bracket and connects the first gear, a housing of the air pump is connected with the bracket, the input shaft of the air pump extends into the bracket and connects the third gear, the first gear meshes with the second gear, the second gear meshes with the third gear, and wherein the engagement-disengagement handle is operable so as to move the second gear in an axial direction to engage with or disengage from the first gear, the engagement-disengagement handle is mounted on the bracket, and an operational end of the engagement-disengagement handle is located on a side of the second gear, and wherein the speed change mechanism is arranged between an output end of the transmission mechanism and the input shaft of the air pump, wherein the output end of the transmission mechanism, the speed change mechanism and the input shaft of the air pump are connected successively, and wherein the air pump is located above the side face of the motor, and an axis of the input shaft of the air pump is in parallel with an axis of the first output shaft of the motor, and wherein when the second gear is engaged with the first gear by the engagement-disengagement handle, the motor is operable to drive the air pump and the winching roller; and wherein when the second gear is disengaged from the first gear by the engagement-disengagement handle, the motor is operable to drive the winching roller.
