Description

Technical Field

[0001] This utility model relates to the field of stacker crane technology, specifically a double-column stacker crane for roadways. Background Technology

[0002] Double-column stacker cranes are a key component of automated storage and retrieval systems (AS / RS). Unlike single-column stacker cranes, their frame structure consists of two columns, an upper crossbeam, and a lower crossbeam, forming a rectangular frame with better structural rigidity and greater weight. They typically have a lifting capacity of up to 5 tons, and can be even greater if necessary, enabling high-speed operation. Double-column stacker cranes operate within aisles between racks, primarily used for handling unitized goods loaded on pallets or in containers. They can also be driven to specific storage compartments, allowing operators to pick and retrieve goods according to outbound requirements.

[0003] Chinese Patent Publication No. CN206783250U discloses a lane-type double-column stacker crane, including a lifting platform, a lifting drive device for traction of the lifting platform, and a forward and backward translational traction device. The lifting platform includes two lifting platforms and a loading platform, on which double-extended forks for unloading materials are installed. Using this invention, the lane-type double-column stacker crane can freely switch between vertical lifting and forward and backward movement. By laying the lower guide rail on the predetermined warehouse floor and keeping it parallel to the warehouse shelves, the lane-type double-column stacker crane can be used in narrow spaces and avoids collisions between the double-extended fork mechanism and the shelves. Simultaneously, a lifting locking safety clamp is installed on the lifting platform, which serves two purposes: firstly, it provides rope breakage protection to prevent the double-extended fork mechanism from falling due to the breakage of the steel wire traction rope; secondly, it allows for real-time control of the lifting height of the lifting platform and the loading platform.

[0004] Existing aisle-type double-column stacker cranes have a fixed fork spacing, which makes them unable to lift goods of different sizes and requires adjustment, which is time-consuming and labor-intensive. Therefore, we propose an aisle-type double-column stacker crane. Utility Model Content
