A stacking device based on attracting type prelifting mainly comprises a moving and vertical conveying device, a horizontal adjusting device and an object fetching device. The horizontal adjusting device is connected in sliding grooves of two guide rails of the moving and vertical conveying device in a sliding mode, and the object fetching device is connected to a horizontal shaft of the horizontal adjusting device in an inserted mode. The moving and vertical conveying device is composed of a vehicle body, a supporting cavity, fixed sheets A, rotating shafts A, wheels A, fixed sheets B, a rotating shaft B, a wheel B, a horizontal hydraulic jack, a rocker, a grab handle, a push rod, a horizontal rod, chain wheels, baffles, chains, lifting bolts A, lifting bolts B, a fixed rod and the guide rails. The horizontal adjusting device is composed of a sliding rod, rotating shafts C, wheels C, a horizontal shaft and a vertical insertion pin. The object fetching device is composed of a cylinder, a connecting rod, a hook A, a connecting base, an air pump and a suction cup. According to the stacking device based on attracting type prelifting, the cost is low, a good conveying function is achieved, objects can be fetched from top to bottom, manual lifting is not needed, manpower is saved, horizontal adjustment is achieved, and rapid object fetching and conveying can be achieved.
