Description

Technical Field

[0001] This utility model relates to the field of material handling device technology, and in particular to a nested quick-release material handling device. Background Technology

[0002] Material handling equipment is a key support for modern logistics and warehousing systems, widely used in factories, warehouses, ports, and other scenarios. Common stacker cranes can flexibly load and unload goods and move them over short distances; conveyors efficiently transport large quantities of goods via continuous conveying; AGVs and AMRs rely on intelligent navigation technology to achieve unmanned and precise handling; cranes and handcarts also play a role in specific scenarios. Among them, stacker cranes, as the core equipment of automated warehousing systems, can achieve precise positioning and retrieval of goods on high-rise shelves due to their high degree of automation. They have advantages such as high operating efficiency and a high degree of automation, and are widely used in logistics warehousing, manufacturing, and other fields.

[0003] Currently available stacker cranes have fixed platform lengths, making it difficult to meet the handling needs of goods of different sizes. In warehousing operations, goods vary in size, from small parts to large boxes, all requiring handling and storage. However, fixed-length platforms cannot accommodate extra-long goods, hindering handling. When handling small goods, the remaining space is large, making the goods prone to swaying. Due to the lack of effective securing and adaptable measures, goods are easily slipped during handling, posing safety hazards and damage risks. To prevent falls, operators must use ropes to secure the goods, which not only increases labor and time costs but also damages the packaging due to frequent binding and unbinding, severely reducing warehousing efficiency and affecting the smooth and safe operation of logistics. Therefore, a nested quick-release material handling equipment is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a nested quick-release material handling device, which aims to improve the problems of fixed platform length of stacker cranes and easy falling of objects during handling.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a nested quick-release material handling equipment, including a stacker crane. Two inner plates are fixedly connected to the outer side of the stacker crane. Dovetail blocks are fixedly connected to both sides of the inner plates. Multiple limiting grooves are opened on the outer side of the dovetail blocks. An outer plate is slidably connected to the outer side of the inner plates. A housing is fixedly connected to both sides of the outer plate. A connecting rod is slidably connected inside the housing. A limiting rod is slidably connected to one side of the connecting rod. A spring is fixedly connected to the other side of the connecting rod. A guide rod is fixedly connected to the other side of the connecting rod. A cylinder is fixedly connected inside the outer plate. A braking assembly is provided on the outer side of the stacker crane.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when handling extra-long goods in industrial settings, standard loading platforms cannot meet the requirements. It is necessary to adjust the lengths of the inner and outer plates. The operator pulls the guide rod, which drives the connecting rod to slide and compress the spring. At the same time, the limiting rod disengages from the limiting groove, releasing the lock on the inner plate. Then, the cylinder installed in the outer plate is activated. Its output end pushes the outer plate to slide along the outer guide rail of the inner plate. When the required length is reached, the guide rod is released, and the spring rebounds, causing the limiting rod to engage with the corresponding limiting groove, thus completing the length adjustment of the loading platform. This provides an adaptable platform for handling, realizes flexible adjustment of the loading platform length, breaks through the limitations of standard specifications, and enables it to adapt to large-sized goods, meeting the needs of different scenarios.

[0022] 2. In this utility model, after the platform is adjusted, the lengths of the inner plate 2 and the outer plate 2 need to be adjusted. The operator pulls the outer guide rod of the outer plate 2 and repeats the above adjustment steps to achieve length adjustment. The motor is started, and through the transmission of the rotating rod, synchronous wheel and synchronous belt, the inner plate 2 slides upward. The stacker is started, and the adjusted inner plate 1 and outer plate 1 are used to transport goods. After the goods are in place, the motor is reversed to allow the inner plate 2 and outer plate 2 to descend and abut against the top of the goods. The goods are fixed by mechanical positive pressure, ensuring safe handling and storage. This achieves stable fixing and safe transfer of goods, greatly improves handling efficiency, and effectively ensures the stability and safety of goods in each stage. Attached Figure Description

[0041] Working principle:

[0042] In industrial material handling scenarios, standard-sized loading platforms are insufficient to handle extra-long cargo. In such cases, length adjustment is required using the inner plate 2 and outer plate 3. The operator first pulls the guide rod 8 outwards. As the guide rod 8 is pulled, the connecting rod 10 slides along the slide rail. During this process, the spring 9 is compressed, storing elastic potential energy. Simultaneously, the connecting rod 10 moves the limiting rod 11, disengaging it from the current limiting groove 5 and releasing the mechanical lock on the inner plate 2. At this point, the mechanism installed on the outer plate 3 is activated. The cylinder 6 inside the inner plate 3 is fixedly connected to the outer side of the inner plate 2. The extension and retraction of the cylinder 6 pushes the outer plate 3 to slide smoothly along the guide rail on the outer side of the inner plate 2. When the outer plate 3 slides to the required length position, the operator releases the guide rod 8. The compressed spring 9 drives the connecting rod 10 to reset by its elastic restoring force, which in turn drives the limiting rod 11 to re-engage in the corresponding limiting groove 5, thus completing the fixation between the inner plate 2 and the outer plate 3 and realizing the length adjustment of the platform, providing a suitable carrying platform for subsequent cargo handling.

[0043] After the platform length is adjusted, to meet the needs of cargo clamping and handling, the lengths of inner plate 18 and outer plate 19 need to be adjusted simultaneously. The operator pulls the outer guide rod 8 of outer plate 19. Through the linkage of guide rod 8, connecting rod 10, spring 9, limit rod 11 and limit groove 5, the platform adjustment steps are repeated to complete the length adjustment of inner plate 18 and outer plate 19. Then, motor 13 is started. The output shaft of motor 13 drives rotating rod 14 to rotate. The synchronous wheel 15 and synchronous belt 16 on the outer side of rotating rod 14 form a transmission mechanism to transmit power to another rotating rod 14, realizing the upward sliding of inner plate 18. At this time, stacker crane 1 is started. The adjusted inner plate 2 and outer plate 3 are used to transport goods. After the goods are transported to the target position, motor 13 is reversed to lower inner plate 18 and outer plate 19, which are tightly pressed against the top of the goods. The goods are firmly fixed by mechanical positive pressure to ensure the safety of subsequent handling and storage.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
