Description

Technical Field

[0001] The utility model relates to the technical field of cargo handling, in particular to an automatic balancing container pallet unloading device. Background Art

[0002] A container is a grouped vehicle that can transport packaged or unpackaged goods and facilitates loading, unloading, and handling using mechanical equipment. Container transportation is a key mode of transport in the multimodal transport of international trade goods. Container transportation, due to its advantages such as high standardization, excellent sealing, low damage rate, intensive operation, large-scale operation, regular shipping, low cost, and high quality, has greatly improved the safety and efficiency of cargo transportation. Currently, international organizations responsible for developing freight container standards include the International Maritime Organization (IMO) and the International Organization for Standardization (ISO).

[0003] The container's greatest success lies in its standardization and the entire transportation system it has enabled. The ability to standardize a massive container capable of carrying tens of tons, and to gradually establish a global logistics system encompassing ships, ports, shipping routes, roads, transit stations, bridges, tunnels, and multimodal transport, is truly one of the greatest miracles ever created by mankind.

[0004] The space of loading cargo containers is narrow, and manual handling is usually adopted within the scope of the containers because it is not suitable to use mechanical equipment for loading and unloading or the working surface is limited and the cargo can only be handled manually. Handling reduces the enthusiasm of workers and thus reduces the efficiency of loading and unloading operations. Utility Model Content

[0005] The purpose of the present invention is to overcome the problems raised in the above background technology and to provide an automatic balancing container pallet unloading device, which can improve the handling efficiency and is simple to operate.

[0006] The purpose of this utility model is mainly achieved through the following technical solutions:

Currently, when loading goods in a container, due to its small internal space, it is not suitable to use mechanical equipment for loading and unloading, or the working surface is limited and the goods can only be handled manually, which reduces the enthusiasm of workers and thus reduces the efficiency of loading and unloading. In order to solve the above problems, this solution designs an automatic balancing container pallet unloading device, including two sets of parallel support frames, the support frames are used to support the whole, and the top surface of the support frames is generally in a horizontal state, so that the materials placed on it can remain stable and will not fall over. A connecting shaft 1 is provided between the support frames, and both ends of the connecting shaft 1 are respectively passed through the support frames and covered with Y-shaped mounting plates, and the Y-shaped mounting plates can rotate along the axis of the connecting shaft 1, and rollers 1 are installed on the branches of the Y-shaped mounting plate, and one roller 1 is installed on each of the three branches of the Y-shaped mounting plate. When moving on flat ground, the two rollers 1 touch the ground, which is more stable. If steps or obstacles are encountered, the Y-shaped mounting plate can rotate to climb over the obstacles, which is more labor-saving. A connecting shaft 2 is provided between the support frames, and both ends of the connecting shaft 2 are respectively passed through the support frames and covered with rollers 2, and the wheel surface of the roller 2 and the wheel surface of the lowest roller 1 are located on the same plane, so that automatic leveling is maintained during movement, so that the pallet placed on the support frame remains level and stable, which can improve the handling efficiency and is simple to operate.

[0008] Furthermore, each support frame is provided with a connecting frame, which is fixed to the top surface of the support frame as an integral structure. A connecting shaft 3 is provided between the connecting frames, and both ends of the connecting shaft 3 are fixed to the support frame. The outer wall of the connecting shaft 3 is covered with a mounting sleeve, and the mounting sleeve is provided with a hook. This structure allows the operator to easily grasp the connecting shaft 3, making it more convenient and labor-saving to push. At the same time, the hook can also be used to connect mechanical equipment to pull the device out of the container.

[0009] Furthermore, a support plate is provided above each support frame, and each support plate is fixed to the top surface of the support frame, and the top surface of the support plate is raised to form an anti-slip boss. By providing the support plate, the force-bearing area of ​​the tray is increased, making it more stable, and the anti-slip boss can prevent the tray from sliding.

[0010] Furthermore, a connecting shaft 4 is provided between the support frames, with both ends of the connecting shaft 4 being fixed to the support frames respectively. An anti-return rod is sleeved on the outer wall of the connecting shaft 4, and the anti-return rod is capable of rotating around the axis of the connecting shaft 4. Since the present solution is to unload the cargo in the container, the only direction of travel after the pallet is placed is toward the outside of the container. In order to prevent collision caused by reverse sliding, an anti-return rod is provided. The end of the anti-return rod away from the connecting shaft 4 is inclined and points downward. When the device retracts, the end of the anti-return rod contacts the ground. As the anti-return rod rotates around the axis of the connecting shaft 4, the contact with the ground becomes deeper, pressing against the device, thereby preventing it from sliding.

[0011] In summary, compared with the existing technology, the utility model has the following beneficial effects: the utility model maintains automatic leveling during movement, so that the pallet placed on the support frame remains level and stable, which can improve the handling efficiency, and is simple to operate, solving the problem of efficiency in loading and unloading operations in narrow spaces of containers.

[0019] like Figure 1 As shown, an automatic balancing container pallet unloading device of this embodiment includes two sets of parallel support frames 7. The support frames 7 are used to support the entire device. The top surface of the support frames 7 is generally horizontal, so that the materials placed on them can remain stable and will not fall over. A connecting shaft 4 is provided between the support frames 7. The two ends of the connecting shaft 4 pass through the support frames 7 and are covered with a Y-shaped mounting plate 5. The Y-shaped mounting plate 5 can rotate along the axis of the connecting shaft 4. The three branches of the Y-shaped mounting plate 5 are respectively equipped with a roller 6. When moving on flat ground, the two rollers 6 touch the ground, which is more stable. If encountering steps or obstacles, the Y-shaped mounting plate 5 can rotate to climb over the obstacles, which is more labor-saving and maintains the balance of the device, so that the pallet placed on it remains stable. A connecting shaft 2 10 is provided between the support frames 7. Both ends of the connecting shaft 2 10 pass through the support frames 7 and are covered with rollers 2 9. The wheel surface of roller 2 9 and the wheel surface of the lowest roller 1 6 are located on the same plane. This structure ensures that the front and rear rollers of the device are always located on the same horizontal plane when the device moves. Since the ground inside the container is flat, the device is in a horizontal state when moving, so that the pallets placed on the support frames remain horizontal and stable, which can improve the handling efficiency and is simple to operate.

[0020] Because the device needs to maintain stability during movement, its center of gravity must be low, resulting in a relatively short structure. Operators cannot bend over for long periods to push the device. Therefore, connecting brackets 3 are installed above the support frames 7. Connecting brackets 3 are fixed to the top surface of the support frames 7 to form an integral structure. Connecting shafts 3 1 are installed between the connecting brackets 3, and both ends of the connecting shafts 1 are fixed to the support frames 7. The outer wall of the connecting shafts 1 is covered with mounting sleeves, which are equipped with hooks 2. This structure allows the operator to easily grasp the connecting shafts 3 1, making it easier and more labor-saving to push. At the same time, the hooks 2 can also be used to connect to mechanical equipment and pull the device out of the container, making movement convenient and labor-saving.

[0021] A support plate 11 is provided above each support frame 7, and each support plate 11 is fixed to the top surface of the support frame 7. The top surface of the support plate 11 is raised to form an anti-slip boss. By providing the support plate 11, the force-bearing area of ​​the tray is increased, making it more stable, and the anti-slip boss can prevent the tray from sliding.

[0022] A connecting shaft 48 is provided between the support frames 7. Both ends of the connecting shaft 48 are fixed to the support frames 7 respectively. An anti-return rod 12 is sleeved on the outer wall of the connecting shaft 48, and the anti-return rod 12 can rotate around the axis of the connecting shaft 48. The connecting shaft 48 is located between the connecting shaft 1 4 and the connecting shaft 2 10. Since the present solution is to unload the goods in the container, the direction of travel after the pallet is placed is only toward the outside of the container. In order to prevent a collision caused by reverse sliding, an anti-return rod 12 is provided. The end of the anti-return rod 12 away from the connecting shaft 48 is inclined and downward. When the device retracts, the end of the anti-return rod 12 contacts the ground. As the anti-return rod 12 rotates around the axis of the connecting shaft 48, the contact with the ground becomes deeper, pressing against the device, thereby preventing it from sliding. This device effectively improves safety measures, is simple to operate, and has high flexibility to improve unloading efficiency.
