A parallel type double-current variable-speed drive device comprises a first power input unit, a second power input unit and a power output unit. The first power input unit comprises a first power divider, a first shaft, a first casing pipe shaft, a first hydraulic pump, odd-gear driving gears and odd-gear synchronizers. The second power input unit comprises a second power divider, a second shaft, a second casing pipe shaft, a second hydraulic pump, even-gear driving gears and even-gear synchronizers. The power output unit comprises a third shaft, a hydraulic motor and odd-even-gear driven gears. The first shaft, the second shaft and the third shaft are arranged in parallel, and the odd-even-gear driven gears of the third shaft are constantly meshed with the odd-gear driving gears of the first casing pipe shaft or/and the even-gear driving gears of the second casing pipe shaft. An oil drain of the first hydraulic pump leads to an oil supply opening of the hydraulic motor, and an oil drain of the second hydraulic pump leads to the oil supply opening of the hydraulic motor. The first shaft or the second shaft is adopted as a power input shaft of the device, and the third shaft is adopted as a power output shaft of the device.
