Automated warehouse storage and retrieval system

An automated warehouse storage and retrieval system comprising:

• at least an aisle, and each of two sides of the aisle having a shelf, and a rail laid along the aisle to enable at least an automated vehicle to move thereon;
• the automated vehicle having a platform, and a top surface of the platform comprising at least a working station and at least a pick-and-place unit thereon;
• each of two lateral sides of the platform having two first openings which are separated by a desired distance, and each of the first openings comprising a climbing unit installed therein;
• each of the climbing units configured to be operated by a telescoping member to synchronously protrude from or move back in the first opening, and each of the climbing units driven by a power unit to have forward or reverse rotation;
• a side of the shelf, which is faced to the rail, having a plurality of vertical supporting members arranged in parallel, and each two adjacent supporting members separated by the distance same as the two climbing units on the same lateral side of the platform;
• the automated vehicle configured to move on the rail to a designated position, and the climbing units pushed out from the first openings by the telescoping members so as to respectively engage with the supporting members of the shelves at the two sides of the aisle;
• the climbing units configured to upwardly or downwardly climb along the supporting members synchronously thereby raising the automated vehicle to a designated height or lowering the automated vehicle back to the rail;
• wherein each of the supporting members of the shelf has two vertical elongated guiding tracks, and each of the guiding tracks comprises an interior space and a vertical elongated opening to form the cross-section of the guiding track in a U-shape, and the two vertical elongated openings on the two guiding tracks are faced toward opposite directions;
• the two guiding tracks of the supporting member are separated by a designed distance, and a vertical lift groove is formed therebetween;
• each of the two guiding tracks has a plurality of chain links secured thereon to form a linear chain in the lift groove, and each of the guiding tracks has a gap at a lower portion;
• and
• wherein each of the climbing units has a base, and the base comprises a backboard and two side boards;
• each of the two side boards has an auxiliary wheel pivotally installed on an inner surface of the side board, and a chain wheel is installed between the two side boards;
• each of the power units installed on either of the two side boards of the base of the climbing unit is connected to and drive the chain wheel;
• each of the telescopic members is connected to the backboard of the climbing units such that each of the climbing units together with the power unit is adapted to be pushed out from or retracted back in the platform of the automated vehicle by the telescopic member.
