Description

Technical Field

[0001] The present application relates to the technical field of roll guide equipment, and more specifically, to a quick-detachable container moving corner wheel. Background Art

[0002] In the field of modern logistics and transportation, containers are undoubtedly a vital means of transportation. They play a key role in various transportation modes such as sea-land transport. In order to achieve efficient stacking and stacking operations, bottom corner fittings are generally installed at the four corners of the bottom of the container. These bottom corner fittings follow a standardized design, allowing containers to be neatly and stably stacked when transferred between different transportation carriers such as ships, trucks, and trains, as well as when stored in the yard, greatly improving the utilization rate of logistics space and the convenience of transportation organization. However, the transfer of containers currently mainly relies on professional equipment such as standard spreaders or forklifts, which is particularly inconvenient. In order to effectively solve the problem of inconvenience in container transfer in the absence of relevant transfer equipment, the industry usually adopts the method of installing corner wheels on the bottom of the container to enhance its maneuverability.

[0003] When installing existing container corner wheels, the rollers are mounted on the bottom corner fittings of the container using devices such as twist locks. The rollers are then mounted to the bottom corner fittings using the twist locks. Using the twist locks to install the rollers requires precise alignment of the mounting holes on the bottom corner fittings and the rollers, and ensuring that the twist locks are fully tightened during installation. This process is relatively complicated, especially when installing multiple corner wheels, as each twist lock requires careful operation, which is very time-consuming. Utility Model Content

[0005] A quick-detachable container moving caster comprises a caster body, a connecting frame is provided on the outside of the caster body, a fixing plate is provided on the top of the connecting frame, and a mounting assembly is provided at one end of the fixing plate;

[0006] The installation assembly includes a rotating card block, a rotating rod is fixedly connected to the inside of the rotating card block, the rotating rod is rotatably connected to the fixed plate, a connecting plate is provided on one side of the fixed plate, and one end of the connecting plate is fixedly connected to the base card block. The structure of the rotating card block is adapted to the structure of the base card block.

[0007] Through the above technical solution, the installation assembly makes the corner wheel body easier and faster to install. In scenarios with frequent logistics transportation and container turnover, it can significantly reduce the time spent on installing and disassembling the corner wheels, and also greatly reduce the labor intensity of operators.

The operation is simple and direct, and does not require the use of complex large tools or the cooperation of multiple people. Compared with the traditional method of disassembling the angle wheel fixed by a large number of bolts or complex twist lock devices, it greatly saves disassembly time and improves work efficiency.

[0011] Furthermore, one end of the connecting plate is fixedly connected to the telescopic plate, the bottom end of the telescopic plate is fixedly connected to the limit block, a counterweight block is provided on one side of the telescopic plate, a placement slot is provided inside the counterweight block, and the telescopic plate is snap-connected to the placement slot.

[0012] With the above technical solution, after the rotating block is connected to the base block, the rotating block needs to be fixed to ensure the stability of the connection and prevent the rotating block from accidentally moving upward and causing the connection to fail. In this case, a counterweight block placed above the rotating block is used to achieve this purpose.

[0013] Furthermore, one end of the telescopic plate is fixedly connected to a connecting piece, and one end of the connecting piece is rotatably connected to a rotating piece.

[0015] Furthermore, a container body is provided on the top of the corner wheel body, and the connecting plate is fixedly connected to the container body.

[0016] Through the above technical solution, the counterweight block can press the rotating block more stably, effectively preventing the rotating block from shifting when the container moves or is impacted by external forces, ensuring that the connection between the corner wheel body and the bottom corner piece of the container is always firm, and ensuring the safety and stability of the entire container transportation process.

[0017] Furthermore, the counterweight block is located above the rotating clamping block.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Reference Figure 1-Figure 5 A quick-detachable container mobile caster includes a caster body 1, a connecting frame 2 is provided on the outside of the caster body 1, a fixing plate 3 is provided on the top of the connecting frame 2, and a mounting assembly is provided at one end of the fixing plate 3;

[0029] The installation assembly includes a rotating block 4, the interior of the rotating block 4 is fixedly connected to a rotating rod 15, the rotating rod 15 is rotatably connected to the fixed plate 3, a connecting plate 8 is provided on one side of the fixed plate 3, one end of the connecting plate 8 is fixedly connected to the base block 5, and the structure of the rotating block 4 is adapted to the structure of the base block 5.

[0030] When installing the corner wheel body 1 to the bottom corner piece at the bottom of the container body 17, first raise the container to a height the same as the length of the corner wheel body 1, then align the base block 5 on one side of the top fixed plate 3 of the connecting frame 2 with the limit plates 6 on both sides of the connecting plate 8, so that it is close to the inner sides of the two limit plates 6, and the limit plates 6 limit the two sides of the rotating block 4, and then push the corner wheel body 1 forward. When the rotating block 4 contacts the base block 5, the rotating block 4 rotates upward and the coil spring 14 winds up. When the structure at one end of the rotating block 4 contacts the groove structure of the base block 5, the coil spring 14 on the rotating rod 15 rebounds, so that the structure of the rotating block 4 is connected to the structure of the base block 5. At this time, the installation of the corner wheel body 1 is completed.

[0031] This installation and disassembly method is simpler and faster than traditional complex connection methods (such as twist locks). In scenarios with frequent logistics transportation and container turnover, such as ports and logistics warehouses, it can significantly reduce the time spent on installing and disassembling corner casters, and also greatly reduces the labor intensity of operators.

[0032] Reference Figure 4-Figure 5 One end of the fixed plate 3 is provided with a placement box 16, one end of the rotating rod 15 extends through the interior of the placement box 16, the inner end of the rotating rod 15 is sleeved with a coil spring 14, and the two ends of the coil spring 14 are respectively fixedly connected to the rotating rod 15 and the placement box 16, one end of the rotating rod 15 extends through the outside of the placement box 16 and is fixedly connected to the rotating handle 9, and both ends of the connecting plate 8 are fixedly connected to the limiting plate 6.

[0033] When removing the corner caster, the handle 9 is rotated. The handle 9 is fixedly connected to the rotating rod 15, so the rotation of the handle 9 drives the rotating rod 15 to rotate. Since one end of the coil spring 14 is connected to the rotating rod 15, the rotation of the rotating rod 15 causes the coil spring 14 to rewind, thereby overcoming the previous resilience of the coil spring 14. This allows the rotating clamping block 4 to rotate upward around the rotating rod 15, disengaging from the connection structure with the base clamping block 5, and releasing the clamping state between the corner caster and the bottom angle piece.

[0034] After rotating the clamping block 4 to disengage the connection, pull the corner wheel body 1 backward to make the base clamping block 5 withdraw from between the limit plates 6 on both sides of the connecting plate 8, thereby removing the corner wheel from the bottom corner piece of the container.

[0035] Reference Figure 1-Figure 4 One end of the connecting plate 8 is fixedly connected to the telescopic plate 7, and the bottom end of the telescopic plate 7 is fixedly connected to the limiting block 11. A counterweight block 10 is provided on one side of the telescopic plate 7. A placement groove is provided inside the counterweight block 10, and the telescopic plate 7 is snapped into the placement groove. One end of the telescopic plate 7 is fixedly connected to a connecting member 12, and one end of the connecting member 12 is rotatably connected to a rotating member 13. A through groove is provided at one end of the placement groove, and the connecting member 12 and the rotating member 13 are both slidably connected to the through groove.

[0036] After the connection between the rotating block 4 and the base block 5 is completed, in order to ensure the stability of the connection and prevent the rotating block 4 from accidentally moving upwards and causing the connection to fail, the rotating block 4 needs to be fixed. At this time, a counterweight 10 placed above the rotating block 4 is used to achieve this purpose.

[0037] First, the telescopic plate 7 starts to extend. Before the rotating block 4 is connected to the base block 5, the telescopic plate 7 is located on one side of the base block 5 and does not affect the operation of the rotating block 4 and the base block 5. The limit block 11 at one end of the telescopic plate 7 moves as the telescopic plate 7 is extended. When the telescopic plate 7 is extended to the appropriate position, the external operator moves the counterweight block 10 toward the limit block 11, so that the limit block 11 contacts the placement groove inside the counterweight block 10 and jams the counterweight block 10, thereby limiting the movement of the counterweight block 10. The rotating block 4 is pressed by the gravity of the counterweight block 10, so that it cannot move upward, thereby ensuring the reliability of the connection between the rotating block 4 and the base block 5.

[0038] Then, the rotating member 13 on one side of the connecting member 12 plays a further fixing role. The rotating member 13 can rotate around the connection point with the connecting member 12. After the telescopic plate 7 is extended and the limit block 11 initially fixes the counterweight block 10, the connecting member 12 and the rotating member 13 are also located inside the through groove of the counterweight block 10 and are in a horizontal state. When the limit groove of the counterweight block 10 is connected to the limit block 11, the rotating member 13 is rotated so that it is located on one side of the counterweight block 10 and is in an inverted L-shaped state, and the counterweight block 10 is fixed again. In this way, through the dual fixation of the limit block 11 and the rotating member 13, the counterweight block 10 can more stably press the rotating block 4, effectively preventing the rotating block 4 from being displaced when the container moves or is impacted by external forces, ensuring that the connection between the corner wheel body 1 and the bottom corner piece of the container is always firm, and ensuring the safety and stability of the entire container transportation process.

[0039] Reference Figure 3-Figure 5 A container body 17 is provided on the top of the corner wheel body 1, the connecting plate 8 is fixedly connected to the container body 17, and the counterweight block 10 is located above the rotating block 4.

[0040] Working Principle: First, preparatory work is required. The telescopic plate 7 is located on one side of the base block 5 and does not interfere with the subsequent docking of the rotating block 4 with the base block 5. To begin installation, the container is first erected to a height equal to the length of the caster body 1. The base block 5 on one side of the top fixing plate 3 of the connecting frame 2 is then aligned with the limit plates 6 on either side of the connecting plate 8, ensuring they rest snugly against the inner side. The limit plates 6 not only position the base block 5 but also limit the subsequent movement of the rotating block 4. The caster body 1 is then pushed forward. Once the rotating block 4 contacts the base block 5, continued movement causes the caster to rotate upward around the rotating rod 15. Simultaneously, the end of the rotating rod 15, located within the storage box 16, causes the coil spring 14 to reel in and accumulate force. When the end of the rotating block 4 contacts the groove in the base block 5, the coil spring 14 rebounds, forcing the rotating block 4 to securely connect with the base block 5, completing the initial installation of the caster body 1.

[0041] A secure connection operation is then performed, causing the telescopic plate 7 to begin extending, and the limit block 11 at its bottom moves accordingly. When the telescopic plate 7 is extended to the appropriate position, the counterweight 10 is moved toward the limit block 11, causing the limit block 11 to snap into the internal placement slot of the counterweight 10. The weight of the counterweight 10 is then used to compress the rotating block 4, preventing it from moving upward. Next, after the limit block 11 secures the counterweight 10, the connecting member 12 and the rotating member 13, which were originally in a horizontal position and located within the through slot of the counterweight 10, are rotated to form an inverted L-shape, contacting one side of the counterweight 10, thereby achieving a secondary fixation of the counterweight 10. This dual fixation method effectively enhances the stability of the connection between the rotating block 4 and the base block 5, ensuring a secure connection between the corner casters and the bottom corner fittings of the container. This prevents the corner casters from loosening or falling off easily during transportation and movement, even if subjected to external impact or vibration, thereby ensuring the safety and stability of the entire transportation process.

[0042] When disassembling the corner wheel, first disassemble the counterweight block 10. After disassembly, retract the telescopic rod 7 to a state where it does not affect the rotation of the rotating block 4. Then rotate the handle 9. The handle 9 is fixedly connected to the rotating rod 15, so the rotation of the handle 9 will drive the rotating rod 15 to rotate. Since one end of the coil spring 14 is connected to the rotating rod 15, the rotation of the rotating rod 15 will cause the coil spring 14 to rewind again, thereby overcoming the previous rebound force of the coil spring 14. In this way, the rotating block 4 can be rotated upward around the rotating rod 15, disengaging from the connection structure with the base block 5, and releasing the clamping state of the corner wheel and the bottom angle piece. After the rotating block 4 is disconnected, pull the corner wheel body 1 backward to make the base block 5 withdraw from between the limit plates 6 on both sides of the connecting plate 8, thereby removing the corner wheel from the bottom angle piece of the container.
