The invention relates to a logistics warehouse quick picking and placing device. The logistics warehouse quick picking and placing device comprises hexagonal prism type shelves, wherein lifting mechanisms are arranged on the middle portions of the hexagonal prism type shelves, and cargo transportation mechanisms are arranged on the lower portions of the hexagonal prism type shelves. Each of the lifting mechanisms comprises a lifting elevator base, and each lifting elevator base is connected with a counterweight block through four lifting cables and a pulley. When the lifting elevator bases arelocated at the lowest position, the tail ends of the cargo transportation mechanisms are connected with the lifting elevator bases. Each of the cargo transportation mechanisms includes driving wheelsat both ends, a conveyer belt for conveying is disposed between the driving wheels, and the conveyor belt is provided with a transport vehicle. According to the technical scheme, the logistics warehouse quick picking and placing device is simple in structure, a plurality of hexagonal prism type shelves which can be connected in a lap joint mode are arranged, the use is flexible and convenient, the pick-and-place efficiency is improved, and the lifting mechanisms are used for quickly transporting cargo to a designated position. The cargo can be effectively prevented from falling by using a microgravity control device, and the normal operation of the cargo transportation is ensured.
