The invention discloses a power-driven anti-explosion winch, and relates to the technical field of hoisting equipment manufacturing. The power-driven anti-explosion winch comprises a winding drum, a low speed motor and a high speed motor, wherein the low speed motor and the high speed motor are respectively connected at the two end axles of the winding drum, one end of the winding drum is sequentially connected with the low speed motor through a first parallel axis reduction gearbox, a first planetary reduction gearbox and a normally-open anti-explosion clutch, and the other end of the winding drum is sequentially connected with the high speed motor through a second parallel axis reduction gearbox and a second planetary reduction gearbox; anti-explosion brakes can be distributed on an input gear of the parallel axis reduction box, an output gear shaft end a motor output end. Compared with the prior art, all parts are conventional products except a structural member, therefore the winch is convenient to design, produce and maintain; furthermore, two single speed motors are distributed on the reduction gearboxes at the two ends of the winch to drive the winch to operate, the motors of different speeds are matched with the reduction gearbox of different speed ratios can be matched to realize the adjustment of the extensive high and low speed scope of the winch, and break through the selectable scope of the speed ratio of a conventional double speed motor.
