Description

Technical Field

[0001] The utility model relates to the technical field of a sawtooth platform for a stereoscopic warehouse, in particular to an automatic safety protection device for a sawtooth platform for a stereoscopic warehouse. Background Art

[0002] In the tobacco logistics sector, automated high-bay warehouses primarily consist of racks, aisle-mounted stackers, loading and unloading workbenches, and automated transport and operation control systems. These warehouses are primarily used for pallet storage. High-bay warehouses typically consist of two-story buildings, with loading operations on the first floor and unloading operations on the second. Unloading operations on the second floor typically require a pallet conveyor docked with the warehouse. Due to the stacker's unique structure, space must be reserved on both sides of the pallet conveyor for the stacker to move around. This necessitates the installation of a zigzag platform on the second floor for unloading operations.

[0003] like Figure 1 The schematic top view of a conventional three-dimensional warehouse shown in FIG. Due to the need for shelving in the warehouse, the three-dimensional warehouse 12 is located in a space spanning two floors. Next to the three-dimensional warehouse 12 are a first floor for incoming goods and a second floor for outgoing goods. On the second floor, near the side of the three-dimensional warehouse, there are a number of second-floor zigzag platforms 13 for accommodating outgoing conveyors.

[0004] Due to the structure of the stacker (which must pick up and place pallets on the outbound conveyor line), the zigzag platforms 13 on the second floor can only be suspended in the three-dimensional warehouse 12. Furthermore, there are no fixed guardrails on either side of each zigzag platform 13. Even in equipment with fixed guardrails, due to the need for pallet placement operations, the fixed guardrails cannot cover the entire zigzag platform operating area.

[0005] In reality, because the sawtooth platform 13 on the second floor does not have corresponding guardrails, when carrying out maintenance, there is a risk of falling from a height after personnel enter the sawtooth platform, which poses a safety hazard. Utility Model Content
