Stereoscopic parking device with chain type lifting driving assembly

The utility model relates to a stereoscopic parking device with a chain type lifting driving assembly. The stereoscopic parking device comprises the chain type lifting driving assembly of an upper-layer tray and a lifting driving assembly of a middle tray. The chain type lifting driving assembly of the upper-layer tray is fixed onto a horizontal transverse beam frame of the uppermost layer of a fixing frame of the stereoscopic parking device, a driving belt pulley is fixed onto a spindle of a speed reducer, and a driven belt pulley and four chain wheels are fixed onto a driven shaft; the driving belt pulley can drive the driven belt pulley via a belt. The stereoscopic parking device has the advantages that the trays can carry out long-stroke lifting actions in up-down directions under the hoisting effects of chains, the chain wheels can be driven to be assuredly meshed with the chains, remaining portions of loose sides of the chains can be effectively stored, parking layers can be increased by the aid of driving hoisting structures of the chains, parking spaces can be effectively utilized, and turnover hammers with weight increasing requirements can be omitted; problems in the aspects of durability and strength due to the fact that steel cables are rolled up by steel cable reels can be solved.
