The invention discloses a combined hanging and conveying device based on chain transmission. The combined hanging and conveying device comprises a base and a driving motor, wherein the driving motor is arranged above the base; upright posts in symmetrical distribution are fixedly arranged on the base; the top ends of the upright posts are provided with an upright post fixing plate in transverse arrangement; the center of the upright post fixing plate is rotationally connected and provided with a vertical rod; a chain transmission mechanism is fixedly arranged on the upright post; an ascendingand descending device and a cargo fork frame are arranged above the base; the two ends of the ascending and descending device are slidingly arranged on the upright post; the cargo fork frame is fixedly arranged at the bottom of the ascending and descending device; the output end of the driving motor is respectively matched and connected with the input end of the vertical rod, the input end of theascending and descending device and the input end of the chain transmission mechanism; movable bottom wheels are fixedly arranged at the bottom of the base. The combined hanging and conveying device overcomes the defect that the distance between a contact point of a cargo upper end steel wire rope and a pulley of the existing hoisting and conveying equipment and a rope winding device is too long.
