Description

Technical Field

[0001] This utility model relates to the field of container technology, specifically to a cantilever crane that operates with a container platform. Background Technology

[0002] Traditional container packing methods primarily involve operations in dedicated areas using specialized equipment, such as forklifts and overhead cranes in factories, and large gantry cranes at docks. These devices are relatively simple and require substantial auxiliary resources, such as fuel and electricity supply, and professional maintenance personnel. While this approach is suitable for large-volume, conventional products, it becomes overly redundant and inflexible when dealing with products with non-repetitive structures, smaller batches, or special requirements, as it necessitates a large amount of auxiliary equipment to ensure smooth operation.

[0003] Especially in special operational locations, such as field military airfields and arid deserts, due to limitations, it is difficult to carry a complete set of supporting equipment. The resulting massive support system not only adds an extra burden but also increases resource costs. Furthermore, since this equipment requires a series of support facilities, such as fuel and power supplies and professional maintenance personnel, its operation undoubtedly becomes a huge support system. During mission execution, such a large support system actually increases additional resource costs and burdens. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: like Figures 1-4 As shown, an embodiment of this utility model discloses a cantilever crane operating with a container platform, comprising a first support platform 1. A plurality of evenly distributed pulleys 101 are fixedly connected to the lower end of the first support platform 1. The pulleys 101 are divided into two groups, with an equal number of pulleys in each group, and are located on opposite sides of the first support platform 1. The first support platform 1 is slidably connected to the container via the pulleys 101. A second support platform 2 is fixedly connected to one end of the first support platform 1. Several cantilever crane bodies 3 are mounted on the second support platform 2. The cantilever crane bodies 3 are detachably mounted on the second support platform 2 via bolts. The cantilever crane bodies 3 can rotate within a 360° range, enabling convenient lifting of goods and placement in designated positions within a 360° range. This satisfies various lifting operations under different working conditions and can assist other modules in their operation, thereby increasing container loading efficiency.

[0020] Among them, the pulley 101 is generally a wheel with a locking function. After the first support platform 1 moves out a part, it can be locked to prevent the first support platform 1 from sliding due to the pulley 101 as much as possible.

[0021] like Figures 1-4 As shown, the cantilever crane body 3 includes a column 4, a mounting platform 401 fixedly connected to the column 4, a rotating arm 6 rotatably connected to the mounting platform 401, a fixed pulley 7 fixedly connected to the end of the rotating arm 6 away from the column 4, a winch mechanism 5 fixedly connected to the column 4, and a wire rope wound on the winch mechanism 5. One end of the wire rope is wound on the winch mechanism 5, and the other end is laid along the column 4 and the rotating arm 6, finally passing through the fixed pulley 7. The end of the wire rope away from the winch mechanism 5 is used to connect to the cargo. The above-described cantilever crane body 3 is common knowledge to those skilled in the art, and will not be described in detail in this embodiment.

[0022] like Figures 1-4As shown, a detachable limiting plate 11 matching the mounting platform 401 is fixedly mounted on the lower end of the rotating arm 6. The limiting plate 11 has multiple second limiting holes 1101. The column 4 has a first limiting hole 4011 matching the second limiting holes 1101. A second insert rod 14 matching the first limiting hole 4011 is inserted into the column 4. The second insert rod 14 passes through the first limiting hole 4011 and then inserts into the second limiting hole 1101. At this time, the mounting platform 401 is locked to the gasket 12 by the second insert rod 14, preventing the rotating arm 6 from continuing to rotate on the mounting platform 401.

[0023] Generally, the number of second limiting holes 1101 is 4 to 15. The more second limiting holes 1101 there are, the more angles that can be locked on the rotating arm 6. The specific number can be set according to the actual use.

[0024] like Figures 1-4 As shown, the lower end of the rotating arm 6 has a first mounting hole 601, and the limiting plate 11 has a second mounting hole 1102 that matches the first mounting hole 601. A first bolt 13 that matches the second mounting hole 1102 is installed on the limiting plate 11. The first bolt 13 passes through the second mounting hole 1102 and is threadedly connected to the first mounting hole 601. The limiting plate 11 is fixedly connected to the first mounting hole 601 by the first bolt 13. When the entire cantilever crane body 3 is damaged, the limiting plate 11 can be disassembled. After replacing the cantilever crane body 3, the limiting plate 11 can be installed on the new cantilever crane body 3, thus realizing the reuse of the limiting plate 11.

[0025] Among them, a washer 12 is fitted on the first bolt 13, and the washer 12 can reduce the possibility of the first bolt 13 loosening to a certain extent.

[0026] In the above embodiments, the cantilever crane operating with the container platform includes a first bearing platform 1 and a second bearing platform 2. The first bearing platform 1 can be moved and fixed inside the container via a pulley 101 with locking function. The cantilever crane body 3 consists of a hoisting mechanism 5, a column 4, a rotating arm 6, and a fixed pulley 7 at the top of the rotating arm 6. This precisely solves the pain points of loading and unloading operations inside containers. Its movable nature allows the equipment to be deployed directly next to the cargo, realizing equipment-cargo-finding and greatly reducing the intermediate steps of repeatedly transferring cargo out of the container in traditional operations. It is particularly suitable for complex scenarios such as bulk cargo loading, emergency repairs, etc., where cargo stacking or equipment installation needs to be completed directly inside the container.

[0027] In harsh environments such as field military airfields and deserts where logistical support is difficult, the core value of this cantilever crane lies in its superior self-sufficiency and flexibility. It cleverly integrates mobility, a compact structure, and precise control capabilities, allowing for direct deployment to container platforms or field equipment, enabling immediate operation once the equipment is in place. This significantly reduces reliance on pre-installed lifting facilities and complex energy supplies, greatly improving the response speed and self-sufficiency of material loading and unloading and equipment maintenance under field conditions, and effectively reducing the size and burden of the logistical support system.

[0028] The core improvement of the cantilever crane body 3 lies in the detachable installation of a limiting plate 11 at the bottom of the rotating boom 6. By inserting the second insert rod 14 into the mounting platform 401 and then inserting the mounting platform 401 into the corresponding second mounting hole 1102, the rotating boom 6 can be locked at multiple different angles to prevent rotation. This detachable multi-angle limiting mechanism achieves flexible positioning and reliable locking of the rotating boom 6, satisfying the flexibility of 360° rotating lifting operations while allowing for quick angle fixation when needed, thus improving operational accuracy and safety. Simultaneously, the modular design makes components such as the limiting plate 11 easy to replace and reuse, facilitating maintenance and reducing operating costs. The overall structure is compact and easily movable, effectively improving loading and unloading efficiency and collaborative operation capabilities within the container platform.

[0029] Example 2: In this embodiment, unlike the embodiments described above, as follows: Figure 2 As shown, there are multiple cantilever crane bodies 3, meaning there are at least two cantilever crane bodies 3. Connecting plates 8 are fixedly connected to each cantilever crane body 3, and a first connecting rod 9 is installed between the two connecting plates 8. The first connecting rod 9 is used to connect adjacent cantilever crane bodies 3. For example, when there are two cantilever crane bodies 3, the first connecting rod 9 is positioned between the two cantilever crane bodies 3 in an H-shape, which further increases the stability of the cantilever crane bodies 3 mounted on the second support platform 2. This design can partially transfer and distribute the force borne by a single cantilever crane to adjacent units, effectively reducing swaying during operation. It is particularly suitable for working conditions requiring coordinated lifting or independent operation. like Figure 2As shown, the connecting plate 8 has a first through hole 801, and the two ends of the first connecting rod 9 have U-shaped grooves 901 that match the connecting plate 8. The first connecting rod 9 also has a second through hole 902 that matches the first through hole 801. The first connecting rod 9 is engaged between the two connecting plates 8 through the U-shaped grooves 901. A first insert rod 10 that matches the second through hole 902 is installed on the first connecting rod 9. The first insert rod 10 passes through the second through hole 902 and the first through hole 801 in sequence. That is, the first connecting rod 9 can be detachably installed between the cantilever crane bodies 3. Similarly, this facilitates the reuse of parts. When the cantilever crane bodies 3 are disassembled, it is also convenient to disassemble a single cantilever crane body 3 without having to disassemble all of the cantilever crane bodies 3.

[0030] Example 3: like Figures 5-7 As shown, a second connecting rod 20 is fixedly connected to the first support platform 1. A gantry frame 15 matching the second connecting rod 20 is installed on the second support platform 2. The cantilever crane body 3 can rotate into the gantry frame 15, which fixes the cantilever crane body 3 inside, preventing large-scale swaying. At the same time, the cantilever crane body 3 facing one end can also increase the area for placing goods on the first support platform 1, which is beneficial for lifting the goods.

[0031] like Figures 5-7 As shown, the portal frame 15 includes a pair of connecting columns 16, which are fixedly connected to both sides of the second support platform 2. A wedge rod 17 is detachably installed on the upper end of the connecting column 16, and the cantilever crane body 3 can rotate into the portal frame 15.

[0032] like Figures 5-7 As shown, the upper end of the connecting post 16 is provided with a insertion groove 1601, and the connecting post 16 is provided with a third mounting hole 1602 that matches the insertion groove 1601. The wedge rod 17 is provided with a fourth mounting hole 1701 that matches the third mounting hole 1602. Both ends of the wedge rod 17 can be inserted into the insertion groove 1601. A second bolt 18 is installed on the connecting post 16. When the wedge rod 17 is inserted into the insertion groove 1601, the second bolt 18 passes through the insertion groove 1601 and the fourth mounting hole 1701 in sequence. A nut 19 is threaded onto the second bolt 18.

[0033] When the cantilever crane is not in use and needs to be stored, it can be rotated into the gantry frame 15. The two ends of the wedge rod 17 are inserted into the insertion slots 1601 at the upper end of the connecting column 16, and the second bolt 18 is passed laterally through the corresponding holes on the connecting column 16 and the wedge rod 17. Finally, the second bolt 18 and nut 19 are tightened to secure the cantilever crane's boom within the gantry frame 15. When it needs to be used, simply unscrew the nut 19, pull out the second bolt 18, and remove the wedge rod 17; the cantilever crane body 3 can then be freely rotated out.

[0034] In this embodiment, by stably storing and fixing the cantilever crane body 3 to one side, the upper space of the first support platform 1 is effectively released, increasing the effective area that can be used to temporarily place goods.

[0035] Finally, a second connecting rod 20 is also installed on the first support platform 1. The second connecting rod 20 cooperates with the gantry frame 15 to bind ropes and fix the goods by ropes.
