The invention belongs to the field of stereo parking devices and particularly relates to a four-column type ascending, descending and horizontal moving two-layer stereo parking device and a use method thereof. The device comprises ground tracks, horizontal moving devices, lifting devices, a second-layer platen, a first-layer platen and a ceiling. The whole parking device is of a four-column supporting bottom traveling structure, horizontal moving is driven through a motor, and ascending and descending are driven through a hydraulic cylinder. The first-layer platen achieves vehicle storing and taking through horizontal moving. The second-layer platen achieves vehicle storing and taking through horizontal moving, ascending and descending. Vehicle obtaining and taking on the first layer and vehicle obtaining and taking on the second layer do not interfere with each other. The device is simple in principle, reliable in structure, convenient to install and high in space utilization rate, the platens do not need to rotate, driving habits and driving directions of vehicle owners do not need to be changed, vehicle storing and taking are convenient, time consumption is small, the device can be used independently and can be combined in a row for use, and use modes are flexible. The device can be used in various environments such as communities, squares, schools and two sides of roads, and environment applicability is high.
