The invention relates to a planetary gear train built-in construction winch device, comprising a rack, a motor, a control switch, and a steel wire rope. The control switch is arranged on the upper part of the rack. The motor is arranged above the control switch. A side of the motor is provided with a coupling. A side of the coupling is provided with a coiling block. The outer side of the coiling block is winded with the steel wire rope. The center of the coiling block is provided with a gear shaft. The gear shaft is provided with a gear planet carrier. A side of the gear shaft is provided with a planet wheel and a planet gear. A side of the planet gear is provided with the planet carrier. Since a planetary wheel reducing mechanism is arranged in the coiling block, weight is reduced, space is reduced, manufacturing cost of the device is low, structure is compact, and use is convenient.
