Description

Technical Field

[0001] This utility model relates to the field of lifting assemblies, specifically to a lifting assembly suitable for containers. Background Technology

[0002] In automated material handling and transportation, materials are loaded into transport vehicles from the supply location and unloaded from the transport vehicles to the destination, requiring basic handling and loading functions to meet transportation requirements. Loading and unloading are crucial links in the logistics process, and with the rapid development of modern cargo loading and transportation technologies, there is an increasing need for automated loading systems to achieve rapid material loading and transfer.

[0003] For large-capacity containers with locking holes, lifting equipment is needed to lift the containers from the input end and then transfer them to the corresponding vehicle body during loading. For containers with locking holes at the top, the current technology still relies on manual labor to position the lifting equipment with the locking holes. For large-capacity containers, the limited space in the vehicle body and the fact that large-capacity containers are more prone to swaying and tilting during lifting are problematic.

[0004] The purpose of this invention is to design a lifting assembly suitable for containers to address the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a lifting assembly suitable for containers, which can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A lifting assembly suitable for containers includes a connecting base, a locking assembly, and a clamping assembly. The locking assembly is flexibly connected to the lower side of the connecting base and includes several guide blocks and locking elements. When the lifting assembly is lowered, the guide blocks engage with the top of the container so that the locking elements are aligned with the locking holes of the container. The clamping assembly is rigidly connected to the lower end of the connecting base. After the lifting assembly is lifted, the clamping assembly clamps the two sides of the container.

[0008] Furthermore, the locking assembly includes a connecting plate whose shape is adapted to the top surface of the container, and the connecting plate is connected to the connecting seat by a hook or chain to form a flexible connection, thereby allowing the connecting plate to move laterally relative to the connecting seat.

[0009] Furthermore, the guide block is disposed on the edge of the connecting plate, extends to the bottom of the connecting plate, and the inner side of the guide block is set as an inclined surface. The guide block is used to adjust the connecting plate to face the top surface of the container.

[0010] Furthermore, the locking component includes a first track horizontally disposed on the connecting plate, the first track being provided with a movable seat, the inner side of the movable seat being provided with a plug rod, the position and shape of the plug rod being adapted to the locking hole of the container, the top end of the movable seat being provided with a pin, and the connecting plate being fixedly provided with a locking lug that cooperates with the pin.

[0011] Furthermore, the clamping assembly includes a second track disposed on the lower end face of the connecting seat, and the second track is provided with a pair of clamping arms that extend below the guide block.

[0012] Furthermore, the connecting plate is provided with a first distance sensor, which is used to obtain the distance between the connecting plate and the top surface of the container.

[0013] Furthermore, the connecting plate is provided with a second distance sensor, which is used to obtain the state of the insertion or withdrawal of the plug into the locking hole.

[0014] Furthermore, the second track is provided with a third distance sensor, which is used to obtain the opening and closing state of the clamping arm.

[0015] Furthermore, force sensors are provided between the corners of the locking assembly and the connecting seat. After the hoisting assembly is lifted, the multiple force sensors obtain the component force of the container on the corners of the locking assembly.

[0016] Furthermore, the locking assembly and the clamping assembly are spaced apart. During the lowering of the hoisting assembly, the locking assembly first faces the top of the container via the guide block and is then connected to the top of the container by its own weight. As the hoisting assembly continues to be lowered, the clamping assembly presses against the top of the locking assembly, and the clamping assembly presses down on the locking assembly so that the locking member faces the locking hole of the container.

[0017] Therefore, this utility model provides the following effects and / or advantages:

[0018] This application uses a locking component of the hoisting assembly that is flexibly connected to the lower side of the connecting seat, and a clamping component that is rigidly connected to the lower end of the connecting seat. Thus, when the hoisting assembly is lowered, the locking component can move laterally through the action of the guide block to adjust its relative position with the container, and finally accurately fit into the top of the container. Then, the clamping component pushes the locking component to fully fit into the top of the container, and at the same time, the clamping component clamps the container to prevent the container from shaking during the hoisting process.

[0019] This application achieves precise execution of various actions during the hoisting process by setting up multiple sensors, which work together with the hoisting assembly and lifting assembly.

[0020] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0021] It should be understood that the above summary and the following detailed description of the present invention are exemplary and explanatory, and are intended to provide further explanation of the present invention as claimed. Attached Figure Description

[0029] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0030] Example 1

[0031] refer to Figure 1A lifting assembly suitable for containers includes a connecting base 41, a locking assembly 42, and a clamping assembly 43. The locking assembly 42 is flexibly connected to the lower side of the connecting base 41 and includes a plurality of guide blocks 421 and locking elements 422. When the lifting assembly is lowered, the plurality of guide blocks 421 cooperate with the top of the container so that the locking elements 422 are aligned with the locking holes of the container 7. The clamping assembly 43 is rigidly connected to the lower end of the connecting base 41. After the lifting assembly is lifted, the clamping assembly 42 clamps the two sides of the container.

[0032] In this embodiment, the lifting assembly is one of the core improvements. Because the locking component 42 and the connecting seat 41 are flexibly connected, such as by a chain or hook, the locking component 42 can move vertically or laterally relative to the connecting seat 41 within a certain range. This is because the locking hole of the container 7 is small and its position is fixed. Existing technologies make it difficult to precisely align the lifting assembly with the top of the container 7. Therefore, by using the flexible connection between the locking component 42 and the connecting seat 41, and with the guiding action of the guide block 421, the locking component 42's own weight, combined with the guidance of the guide block 421, allows it to automatically align with the top of the container 7 during the lowering process. Under the lowering action of the lifting assembly 3, the locking component 42 can be fitted onto the top of the container, achieving the desired effect. Figure 2 The locked state is shown.

[0033] At this time, the locking component 42 may have a certain offset relative to the connecting seat 41. After the hoisting assembly is lifted, the container 7 is suspended in the air. Under its own weight, the container 7 drives the locking component 42 to face the connecting seat 41. Then, the clamping component 42 clamps the container 7 on both sides, so that the length direction of the container 7 is consistent with the lifting direction of the lifting assembly 3, thereby preventing the container 7 from shaking during the hoisting process.

[0034] Furthermore, the locking assembly 42 includes a connecting plate 423, the shape of which is adapted to the top surface of the container 7. The connecting plate 423 and the connecting seat 41 are connected by a hook 424 or a chain to form a flexible connection, thereby allowing the connecting plate 423 to move laterally relative to the connecting seat 41.

[0035] The guide block 421 is disposed on the edge of the connecting plate 423 and extends to the bottom of the connecting plate 423. The inner side of the guide block 421 is set as an inclined surface. The guide block 421 is used to adjust the connecting plate 423 to face the top surface of the container.

[0036] In this embodiment, reference Figure 4The top of the inclined surface of the guide block 421 is flush with the edge of the connecting plate 423. The guide block 421 extends below the connecting plate 423, so that during the lowering of the locking assembly 42, the bottom end of the guide block 421 contacts the top of the container 7 first. Under the action of the guide block 421, the connecting plate 423 is aligned with the upper end of the container 7. At the same time, the hook 424 or chain connection forms a flexible connection, which facilitates the lateral or vertical movement of the connecting plate 423 relative to the connecting seat 41, thereby facilitating the lateral or vertical movement of the connecting plate 423 caused by the guiding action of the guide block 421.

[0037] Furthermore, the locking member 422 includes a first track 4221 horizontally disposed on the connecting plate 423. The first track 4221 is provided with a movable seat 4222. The inner side of the movable seat 4222 is provided with a plug rod 4223. The position and shape of the plug rod 4223 are adapted to the locking hole of the container 7. The top of the movable seat 4222 is provided with a pin 4224. The connecting plate 423 is fixedly provided with a locking lug 4225 that cooperates with the pin 4224.

[0038] In this embodiment, reference Figure 4 The movable seat 4222 can move laterally via the first track 4221. After it moves inward, it can drive the insertion rod 4223 to be inserted into the locking hole of the container. At the same time, in order to prevent the insertion rod 4223 from moving, the locking lug 4225 provided on the connecting plate 423 in this embodiment can cooperate with the pin 4224. After the handle drives the pin 4224 to be inserted into the locking lug 4225, the movable seat 4222 cannot move laterally, thereby restricting the insertion rod 4223 from disengaging from the locking hole.

[0039] Furthermore, the clamping assembly 43 includes a second track 431, which is disposed on the lower end face of the connecting seat 41. The second track 431 is provided with a pair of clamping arms 432, which extend below the guide block 421.

[0040] In this embodiment, reference Figure 3 The clamping arm 432 can be a horizontally oriented, open shape, with its width adapted to the width of the container. Simultaneously, the second track 431 can be equipped with a drive motor, thereby driving the second track 431 to move laterally and causing the clamping arm 432 to open or close. The clamping arm 432 extends below the guide block 421 to avoid contact with the guide block 421 during its approach, preventing the clamping arm 432 from colliding with the guide block 421.

[0041] Further, refer to Figure 5-6 The connecting plate 423 is provided with a first distance sensor 425, which is used to obtain the distance between the connecting plate 423 and the top surface of the container 7;

[0042] The first distance sensor 425 shines downward through the connecting plate 423 to obtain the distance between the connecting plate 423 and the top surface of the container 7. This distance can be used to determine the position of the lifting assembly 3 as it descends to the top of the container 7, and whether the connecting plate 423 is close to / approaches / fits into the top of the container 7, thereby precisely controlling the descent depth of the lifting assembly 3.

[0043] The connecting plate 423 is provided with a second distance sensor 426, which is used to obtain the state of the insertion rod 4223 being inserted into or withdrawn from the locking hole.

[0044] The second track 431 is provided with a third distance sensor 433, which is used to obtain the opening and closing state of the clamping arm 432;

[0045] The connecting plate 423 is provided with a fourth distance sensor 411, which is used to obtain the distance between the connecting plate 423 and the ground.

[0046] The distance obtained by the fourth distance sensor 411 can be used to determine the height of the lifting assembly 3. Combined with the value of the first distance sensor 425, the two can be combined to obtain the height of the top of the container 7 relative to the ground, thereby accurately controlling the lifting assembly 3 to move the connecting plate 423 toward the top of the container 7.

[0047] Force sensors 427 are provided between the corners of the locking assembly 42 and the connecting seat 41. After the hoisting assembly 3 is lifted, the multiple force sensors 427 obtain the component force of the container 7 on the corners of the locking assembly 42.

[0048] In this embodiment, when the insertion rod 4223 is correctly inserted into the locking hole of the container 7 and the pin 4224 is inserted into the locking lug 4225, after lifting the container 7, each force sensor 427 should be assigned the same or similar component of the gravity generated by each container 7. If the value of one or more force sensors 427 deviates significantly, it can be deduced that the insertion rod 4223 or pin 4224 is not locked or other issues have occurred. In this case, violent shaking or tilting of the container 7 is likely to occur during the hoisting process. Alternatively, after lifting the container 7, the container 7 may sway from side to side, which will also cause a significant deviation in the value of one or more force sensors 427. Therefore, force sensors 427 are needed for this determination. Furthermore, the locking assembly and the clamping assembly are spaced apart. During the lowering of the hoisting assembly, the locking assembly first faces the top of the container via the guide block and is then connected to the top of the container by its own weight. As the hoisting assembly continues to be lowered, the clamping assembly presses against the top of the locking assembly, and the clamping assembly presses down on the locking assembly so that the locking member faces the locking hole of the container.

[0049] Furthermore, the locking assembly 42 and the clamping assembly 43 are spaced apart. During the lowering process of the hoisting assembly 3, the locking assembly 42 first faces the top of the container 7 via the guide block 421, and is connected to the top of the container 7 by its own weight. When the hoisting assembly 3 is lowered further, the clamping assembly 43 presses against the top of the locking assembly 42, and the clamping assembly 43 presses down on the locking assembly 42 so that the locking member 42 faces the locking hole of the container 7.

[0050] In this embodiment, reference Figure 7 The distance between the first track 4221 and the second track 431 is set so that, with the locking assembly 42 flexibly connected to the connecting seat 41, when the locking assembly 42 reaches the upper end of the container 7, the lifting assembly 3 continues to descend a short distance. The distance between the first track 4221 and the second track 431 is maintained, allowing the locking assembly 42 to descend under its own weight and fit into the upper end of the container 7. Next, the lifting assembly 3 continues to descend, causing the first track 4221 to begin contacting the second track 431. Driven by the lifting assembly 3, the first track 4221 begins to press down on the second track 431, thereby pressing down on the locking assembly 42 so that it is completely fitted into the upper end of the container 7.
