Description

Technical Field

[0001] This utility model relates to the field of cargo platform technology, and in particular to a cargo platform for a monorail stacker crane. Background Technology

[0002] The loading platform of a monorail stacker crane is a component installed on the stacker crane's columns or traveling mechanism to carry goods. It can realize the picking, placing and transferring of goods through lifting and telescopic mechanisms. It is adapted to the space limitations of monorail tracks and is mostly used in narrow aisle warehouses, small automated warehouses, or occasions with high space utilization requirements. It is suitable for the automated storage and retrieval of lightweight and small-sized goods, and can efficiently utilize vertical space to improve the efficiency of warehousing operations.

[0003] The loading platform of the monorail stacker crane moves horizontally along the monorail track via a drive device. After arriving at the designated cargo position, the lifting mechanism drives the platform to rise vertically to the corresponding height. Then, the telescopic forks or push plates extend to pick up or put down the goods from the rack. After the operation is completed, all mechanisms reset. The entire process relies on sensors and a control system for precise positioning to achieve automated cargo transfer and is suitable for efficient operation under the space constraints of a monorail.

[0004] Currently, some monorail stacker cranes on the market cannot achieve the effect of monitoring the length, width and height of goods and facilitating unloading through mechanical structure. Therefore, a new cargo platform for monorail stacker cranes is proposed to solve the above problems. Utility Model Content

The top of the cargo pallet has two forklift unloading auxiliary grooves with smooth chamfered outer edges. The bottom of the cargo pallet is fixedly connected to four fixing plates, and bolts are threaded to each pair of fixing plates on opposite sides in the horizontal direction. The external threads of the bolts are connected to the interior of the cargo beam. The interior of the cargo pallet has several load-bearing hollows.

The outer edge of the sliding steel frame is designed with a smooth chamfer.

[0010] As a further description of the above technical solution: four shafts are fixedly connected to the inner side of the sliding steel frame, and rollers are fixedly connected to the outer side of each of the four shafts. A fixing ring is fixedly connected to the outer end of each shaft, and the outer side of each roller is slidably connected to the transport track. The outer edge of each roller is designed with a smooth chamfer.

[0011] As a further description of the above technical solution: the shock absorption component includes an elastic baffle, the bottom of which is slidably connected to the top of the two cargo beams, four movable rods are fixedly connected to the rear side of the elastic baffle, four fixed rods are fixedly connected to the outer side of the drive component, and four springs are fixedly connected to the rear side of the elastic baffle, with the outer ends of the four springs all fixedly connected to the inner side of the sliding steel frame.

[0027] Working principle: When the loading platform of this monorail stacker crane is in operation, the loading operation is performed first. The goods are placed on the loading pallet 21, which is fixed to the loading beam 1 by the bottom fixing plate 23 and bolts 24 to ensure stability during the loading process. The several load-bearing hollows 25 inside the loading pallet 21 reduce its own weight without affecting the load-bearing capacity of the goods. After loading is completed, the drive component 4 starts to work, driving the loading platform to move. The fixed load-bearing block 41 fixes the sliding steel frame 42 to the loading beam 1. Rollers 44 on the outside of shaft 43 slide on the transport track. Fixing ring 45 prevents shaft 43 from falling out of sliding steel frame 42, thus achieving smooth movement of the cargo platform. During the movement, monitoring component 3 monitors the status of the cargo in real time. Extended support block 31 provides support for top rod 32. Connecting plate 33 on top rod 32 fixes support rod 34. Overheight detector 35 on top of support rod 34 monitors whether the cargo is too high. Cargo position virtual / real detector 37 monitors whether there is cargo in the cargo position. Overwidth detector 36 monitors whether the cargo is too wide, ensuring transportation safety.

[0028] When the loading platform moves to the designated position for unloading, the shock absorption component 5 comes into play. If a slight collision occurs during the unloading process, the elastic baffle 51 will compress the spring 54 through the movable rod 52. The elastic force of the spring 54 acts on the sliding steel frame 42, which plays a role in buffering and shock absorption, protecting the goods and the platform. The forklift can unload through the forklift unloading auxiliary groove 22 on the top of the loading pallet 21. The smooth chamfer design of the outer edge of the groove makes it easy for the forklift forks to insert.
