Description

Technical Field

[0001] This invention belongs to the field of hoisting equipment technology, specifically a container rotating unloading spreader. Background Technology

[0002] A shipping container is a large cargo container with sufficient strength, reusability, and ease of mechanical loading and unloading. It is commonly used to load bulk materials such as ores. During transshipment, containers are often lifted using spreader equipment and transported to a designated unloading point. The container is then driven to tilt or overturn in the air to unload the cargo.

[0003] Patent CN221587790U discloses a bulk container tipping spreader, including a spreader frame, a rotating frame, locking components, and rotating components. The rotating frame is rotatably mounted inside the spreader frame at both ends via two sets of trunnions. Two sets of rotating components are fixedly installed inside the spreader frame on both sides of the rotating frame. A rotating worm gear is fixedly installed on each trunnion on both sides of the rotating frame, and the output end of the rotating component is connected to the rotating worm gear. Two sets of locking components are symmetrically installed on the top inner side of the rotating frame. The rotating frame is locked and fixed to the top of the container via the locking components. This patent simplifies the overall unloading process and saves unloading costs.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: The spreader is secured by connecting its locking head to the mating holes on the container, while a clamping device holds the container in place, creating a stable connection between the spreader and the container. The crane then lifts the container to the designated unloading point and rotates it to achieve unloading.

[0005] When materials fall out of the container opening, the range of material falling depends on the size of the container opening. In some cases, it is necessary for the materials to fall into one or more material bins of the same size so that they can be stored and transferred uniformly in the future. However, when the opening size of the material bin is smaller than the opening size of the container, some materials will fall outside the material bin during the dumping process, thus affecting the normal collection of materials.

[0030] Specifically, in existing technology, the locking head on the spreader is connected and fixed to the mating hole on the container, while a clamping device is used to hold the container, thus forming a stable connection between the spreader and the container. The crane then lifts the container to the designated unloading point and drives it to rotate, thereby achieving unloading.

[0031] When materials fall out of the container opening, the range of material falling depends on the size of the container opening. In some cases, it is necessary for the materials to fall into one or more material bins of the same size so that they can be stored and transferred uniformly in the future. However, when the opening size of the material bin is smaller than the opening size of the container, some materials will fall outside the material bin during the dumping process, thus affecting the normal collection of materials.

[0032] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: This solution is applied to unloading bulk materials from a container into one or more identical material bins. The frame 1 is connected to the hoist via the lifting lug 2. Initially, the bottom of the unloading bin 5 is higher than the bottom of the tipping frame 6. The hoist moves the frame 1 above the container. Based on the container's dimensions, motor 7 18 drives the bidirectional threaded rod 2 34 to rotate, adjusting the distance between the two sliders 10 on the same crossbeam 8. Simultaneously, motor 4 37 drives the threaded rod 1 9 to rotate, adjusting the distance between the two crossbeams 8. The hoist also adjusts the angle and orientation of the frame 1, aligning the four locking devices 11 with the mating holes at the four corners of the container. The locking heads of the locking devices 11 are then inserted into the mating holes, and rotating them achieves the locking effect. The connection between the locking devices 11 and the mating holes is existing technology and will not be elaborated further here. At the same time, motor 213 drives the bidirectional threaded rod 12 to rotate, causing the two reinforcing plates 14 to slide and move closer to each other, thus using the reinforcing plates 14 to clamp the container and further reinforce it.

[0033] Then, the frame 1 is lifted using a hoist. When the container moves above the designated unloading point, the hydraulic cylinder 3 is activated, driving the connecting rod 4 to rotate on the frame 1, thus moving the unloading box 5 below the container. Since the guide plate 27, the inclined plate 30, the inclined plate 31, and the inner wall of the unloading box cooperate to form the discharge port, the size of the discharge port can be adjusted by the cylinder 28 driving the guide plate 27 to move laterally and the cylinder 29 driving the inclined plate 30 to move laterally. Furthermore, when the guide plate 27 moves laterally, the guide plate 26 slides on the guide plate 25, and both rotate simultaneously. The inclined plate 31 will also move relative to the inclined plate 30. Furthermore, as inclined plates 2 (31) and 1 (30) move, they respectively pull the ends of fabric 3 (40) and fabric 2 (39), causing take-up shaft 1 (43) and take-up shaft 2 (46) to rotate simultaneously, unwinding fabric 3 (40) and fabric 2 (39). Meanwhile, torsion springs 1 (44) and 2 (45) deform, keeping the unwound portions of fabric 3 (40) and fabric 2 (39) taut. Through the coordination of these structures, the size of the material discharge port can be adjusted to match the opening size of the material bin, while preventing any excess gaps at the discharge port. When multiple material bins are placed side-by-side below the unloading box 5, with the opening of the leftmost material bin aligned with the leftmost discharge port, and so on, the openings of multiple material bins will align with multiple discharge ports. Additionally, to facilitate the placement of the material bins and prevent them from shifting during receiving, the side-by-side material bins are usually positioned close together. However, under normal circumstances, the opening diameter of the material bucket is smaller than its own maximum diameter. Therefore, when multiple material buckets are placed side by side, the opening distance between two adjacent material buckets is fixed. The above operation can only match the size of the discharge port with the opening of the material bucket. Therefore, when the distance between adjacent discharge ports is different from the distance between adjacent openings, multiple discharge ports still cannot be aligned with the openings of multiple material buckets placed side by side. Therefore, to solve this problem, the cylinder 17 drives one side of the partition 20 to slide in the chute. The other partitions 20 will also move synchronously under the transmission of the connecting rod 32 and the connecting rod 33, adjusting the distance between two adjacent partitions 20. Furthermore, while the partitions 20 are moving, the above adjustment operation can be used again to keep the size of the discharge port unchanged until the distance between adjacent discharge ports is equal to the distance between adjacent openings. At this time, when multiple material buckets are placed side by side under the unloading box 5, as long as the opening of the leftmost material bucket is aligned with the leftmost discharge port, the openings of the other material buckets will also be aligned with the other discharge ports.

[0034] At this point, based on the number of material bins, motor 437 drives threaded rod 215 to rotate, causing baffle 19 to move laterally. Simultaneously, motor 35 drives roller 36 to rotate, unwinding fabric 16 and keeping the unwound portion of fabric 16 taut until baffle 19 aligns with the corresponding partition 20. At this point, the number of discharge ports on the left side of baffle 19 is the same as the number of material bins. Then, motor 7 drives tilting frame 6 to rotate, tilting the container. The material in the container will fall into unloading box 5, dropping along the surface of fabric 16 and the inner wall of unloading box 5 from each discharge port and accurately into each material bin. By controlling the dropping range, the material is distributed into each material bin, preventing material from falling outside the bins during the pouring process, thus ensuring proper material collection. Furthermore, during placement, the material bins only need to be placed side-by-side to ensure that multiple discharge ports are simultaneously aligned with the bin openings, which is quite convenient.

[0035] Furthermore, as the material falls out along the discharge port, it can fall smoothly without accumulating because the guide plate 25, guide plate 26, inclined plate 30, inclined plate 31, material cloth 39, and material cloth 40 are all inclined. In addition, the chute on the unloading box 5 for adjusting the partition 20 is narrow, making it difficult for material to fall outside the chute, and any small amount of material spillage is negligible.

[0036] In this embodiment, as Figure 5 , Figure 8 , Figure 9 As shown, it also includes a blocking component; The blocking assembly includes a second baffle 23 rotatably disposed on one side of the upper end of the partition 20, a third baffle 24 inserted into and slidably connected to the inner side of the second baffle 23, and a telescopic plate 47 inserted into and slidably connected to the inner side of the first baffle 19.

[0037] A motor 6 21 is fixedly connected to one side of the upper end of the partition 20, and the output end of the motor 6 21 is fixedly connected to one end of the baffle 2 23.

[0038] A threaded rod 22 is threadedly connected to one side of baffle 3 24. One end of the threaded rod 22 is rotatably mounted on baffle 2 23. A motor 38 is fixedly connected to one side of the inner cavity of baffle 2 23. The output end of motor 38 is fixedly connected to one end of threaded rod 22. A threaded rod 48 is threadedly connected to one side of telescopic plate 47. One end of threaded rod 48 is rotatably mounted in the inner cavity of baffle 1 19. A motor 18 is fixedly connected to one side of the inner cavity of baffle 1 19. The output end of motor 18 is fixedly connected to one end of threaded rod 48.

[0039] Specifically, in the above embodiments, although the material can be divided into multiple material buckets, the discharge amount of each outlet is random, so the filling speed of each material bucket is also different. When a material bucket is full, in order to avoid the material overflowing, it needs to be moved away from under the unloading box 5. This will cause the material falling out of the outlet to fall on the ground, which will also cause the material to spill out.

[0040] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: Each set of baffles 23 and 34 corresponds to a discharge port. When the material bucket corresponding to the discharge port is full, motor 6 21 drives baffles 23 and 34 to rotate 90 degrees. Furthermore, based on the distance between two adjacent partitions 20, motor 5 38 drives threaded rod 3 22 to rotate, causing baffle 3 24 to slide within the cavity of baffle 23 until the end of baffle 3 24 is in contact with another partition 20, thus covering the discharge port and preventing material from falling to the ground. In addition, since baffle 19 needs to be aligned with partition 20, baffle 19 will also be aligned with baffles 34 and 23, and the end of baffle 19 will be in contact with baffle 3 24 to prevent material overflow due to a large gap between them. When baffles 24 and 23, which are aligned with baffle 19, rotate, a gap appears between baffle 19 and partition 20, causing material to flow to the discharge port on the right side of baffle 19, resulting in material spillage. Therefore, to avoid this problem, when baffles 24 and 23 rotate, the telescopic plate 47 in baffle 19 also moves under the action of the threaded rod 48 driven by motor 18, causing the end of the telescopic plate 47 to fit against the corresponding partition 20, thus filling the gap and further preventing material spillage.

[0041] Working principle: The frame 1 is connected to the hoist via the lifting lug 2. In the initial state, the bottom of the unloading box 5 is higher than the bottom of the tilting frame 6. The hoist moves the frame 1 above the container. Based on the container's dimensions, motor 7 18 drives the bidirectional threaded rod 2 34 to rotate, adjusting the distance between the two sliders 10 on the same crossbeam 8. Simultaneously, motor 4 37 drives the threaded rod 1 9 to rotate, adjusting the distance between the two crossbeams 8. The hoist also adjusts the angle and orientation of the frame 1, aligning the four locking devices 11 with the mating holes at the four corners of the container. The locking head of the locking device 11 is then inserted into the mating hole, and the locking head is rotated to achieve the locking effect. The connection between the locking device 11 and the mating hole is existing technology and will not be elaborated further here. Simultaneously, motor 2 13 drives the bidirectional threaded rod 12 to rotate, causing the two reinforcing plates 14 to slide and move closer together, thus clamping the container and further reinforcing it.

[0042] Then, the frame 1 is lifted using a hoist. When the container moves above the designated unloading point, the hydraulic cylinder 3 is activated, driving the connecting rod 4 to rotate on the frame 1, thus moving the unloading box 5 below the container. Since the guide plate 27, the inclined plate 30, the inclined plate 31, and the inner wall of the unloading box cooperate to form the discharge port, the size of the discharge port can be adjusted by the cylinder 28 driving the guide plate 27 to move laterally and the cylinder 29 driving the inclined plate 30 to move laterally. Furthermore, when the guide plate 27 moves laterally, the guide plate 26 slides on the guide plate 25, and both rotate simultaneously. The inclined plate 31 will also move relative to the inclined plate 30. Furthermore, as inclined plates 2 (31) and 1 (30) move, they respectively pull the ends of fabric 3 (40) and fabric 2 (39), causing take-up shaft 1 (43) and take-up shaft 2 (46) to rotate simultaneously, unwinding fabric 3 (40) and fabric 2 (39). Meanwhile, torsion springs 1 (44) and 2 (45) deform, keeping the unwound portions of fabric 3 (40) and fabric 2 (39) taut. Through the coordination of these structures, the size of the material discharge port can be adjusted to match the opening size of the material bin, while preventing any excess gaps at the discharge port. When multiple material bins are placed side-by-side below the unloading box 5, with the opening of the leftmost material bin aligned with the leftmost discharge port, and so on, the openings of multiple material bins will align with multiple discharge ports. Additionally, to facilitate the placement of the material bins and prevent them from shifting during receiving, the side-by-side material bins are usually positioned close together. However, under normal circumstances, the opening diameter of the material bucket is smaller than its own maximum diameter. Therefore, when multiple material buckets are placed side by side, the opening distance between two adjacent material buckets is fixed. The above operation can only match the size of the discharge port with the opening of the material bucket. Therefore, when the distance between adjacent discharge ports is different from the distance between adjacent openings, multiple discharge ports still cannot be aligned with the openings of multiple material buckets placed side by side. Therefore, to solve this problem, the cylinder 17 drives one side of the partition 20 to slide in the chute. The other partitions 20 will also move synchronously under the transmission of the connecting rod 32 and the connecting rod 33, adjusting the distance between two adjacent partitions 20. Furthermore, while the partitions 20 are moving, the above adjustment operation can be used again to keep the size of the discharge port unchanged until the distance between adjacent discharge ports is equal to the distance between adjacent openings. At this time, when multiple material buckets are placed side by side under the unloading box 5, as long as the opening of the leftmost material bucket is aligned with the leftmost discharge port, the openings of the other material buckets will also be aligned with the other discharge ports.

[0043] At this point, based on the number of material bins, motor 37 drives threaded rod 15 to rotate, causing baffle 19 to move laterally. Simultaneously, motor 35 drives roller 36 to rotate, unwinding fabric 16 and keeping the unwound portion of fabric 16 taut until baffle 19 aligns with the corresponding partition 20. At this point, the number of discharge ports on the left side of baffle 19 is the same as the number of material bins. Then, motor 7 drives tilting frame 6 to rotate, causing the container to tilt. The material in the container will fall into unloading box 5, dropping along the surface of fabric 16 and the inner wall of unloading box 5 from each discharge port and accurately into each material bin.

[0044] Furthermore, as the material falls out along the discharge port, it can fall smoothly without accumulating because the guide plate 25, guide plate 26, inclined plate 30, inclined plate 31, material cloth 39, and material cloth 40 are all inclined. In addition, the chute on the unloading box 5 for adjusting the partition 20 is narrow, making it difficult for material to fall outside the chute, and any small amount of material spillage is negligible.

[0045] Each set of baffles 23 and 34 corresponds to a discharge port. When the material bucket corresponding to the discharge port is full, motor 6 21 drives baffles 23 and 34 to rotate 90 degrees. Furthermore, based on the distance between two adjacent partitions 20, motor 5 38 drives threaded rod 3 22 to rotate, causing baffle 3 24 to slide within the cavity of baffle 23 until the end of baffle 3 24 is in contact with another partition 20, thus covering the discharge port and preventing material from falling to the ground. In addition, since baffle 19 needs to be aligned with partition 20, baffle 19 will also be aligned with baffles 34 and 23, and the end of baffle 19 will be in contact with baffle 3 24 to prevent material overflow due to a large gap between them. When baffles 24 and 23, which are aligned with baffle 19, rotate, a gap appears between baffle 19 and partition 20, causing material to flow to the discharge port on the right side of baffle 19, resulting in material spillage. Therefore, to avoid this problem, when baffles 24 and 23 rotate, the telescopic plate 47 in baffle 19 also moves under the action of the threaded rod 48 driven by motor 18, causing the end of the telescopic plate 47 to fit against the corresponding partition 20, thus filling the gap and further preventing material spillage.
