Description

Technical Field

[0001] This utility model relates to the field of logistics equipment, and in particular to a lifting device that supports flexible locking. Background Technology

[0002] In the current logistics field, material handling is a crucial link, directly affecting production efficiency, operational safety, and cost control. In traditional material handling methods, large material crates, after being loaded with materials, often carry a weight exceeding 200 kg, making direct manual handling extremely difficult and impractical. Manual handling is not only inefficient but also poses significant safety risks, easily leading to worker injuries, and does not meet the requirements of modern industry for safe production and humanized operations.

[0003] To address this challenge, the logistics industry has been exploring more efficient and safer material handling solutions. However, existing lifting equipment generally has certain limitations in its design, making it difficult to fully adapt to the handling needs of such heavy-duty material crates. Specifically, many lifting devices are insufficient in terms of load-bearing capacity, operational flexibility, and adaptability to material crates of different sizes and shapes; for example, some lifting devices may not meet sufficient load-bearing standards to safely lift material crates exceeding 200kg; others may lack in structural compatibility, operational complexity, precise control, or spatial adaptability, making it difficult to complete handling tasks efficiently and stably in practical applications.

[0004] Therefore, developing a new type of lifting device that can meet the needs of heavy-duty material handling while also possessing good operational flexibility and wide adaptability has become an urgent technical problem to be solved in the logistics field. This device needs to overcome the limitations of existing technologies and ensure that while guaranteeing operational safety, it can significantly improve the efficiency and quality of material handling, thereby promoting the further development of the logistics industry.

[0007] Stopping mechanisms and scissor linkage mechanisms;

[0008] The scissor linkage mechanism includes: at least two sets of first cross components arranged symmetrically and connected to each other, each set of first cross components having a clamping component at its lower end, the clamping component being used to hook up the logistics frame to be lifted, and the first cross components being used to limit the clamping distance of the clamping component during the cross action;

[0009] The stopping mechanism includes: at least two sets of second hinge components that are symmetrically arranged and interconnected with each other, each second hinge component corresponding to a first cross component, and the lower end of the second hinge component being hinged to the upper end of the first cross component; a stop control component is rotatably connected between the two second hinge components; the second hinge components are used to limit the cross movement range of the first cross component during hinge action; the stop control component is used to lock or unlock the hinge action of the second hinge components.

[0010] As an improved solution, each set of the first cross components includes: a pair of first lifting frames that are hinged to each other;

[0011] The two first lifting frames are arranged to cross each other, and the two first lifting frames are hinged to each other at the intersection.

[0012] The lower end of the second hinge assembly is connected to the upper ends of the two first lifting frames respectively, and the clamping assembly is connected to the lower ends of the two first lifting frames.

[0013] As an improved solution, in the two sets of first cross components, the upper and lower ends of the two symmetrical first lifting frames are connected to each other by horizontally arranged first connecting rods.

[0014] As an improved solution, each set of the second hinge assembly includes: a pair of second lifting arms that are hinged to each other;

[0015] Each pair of second lifting frames corresponds to a pair of first lifting frames of a set of first cross components, and the second lifting frames correspond one-to-one with the first lifting frames;

[0016] The upper ends of the two second lifting frames are hinged to each other, and the lower ends of the two second lifting frames are respectively hinged to the upper ends of the corresponding two first lifting frames.

[0017] As an improved solution, in the two sets of second hinge assemblies, the upper ends of the two inner second lifting frames are connected to each other by a horizontally arranged second connecting rod.

[0018] As an improved solution, the stop control assembly includes: a stop hook and a stop handle;

[0019] The stop hook is vertically arranged, and the upper end of the stop hook is rotatably connected to the middle position of the second connecting rod, and the lower end of the stop hook is a hook groove.

[0020] The stop handle is connected to the side wall of the stop hook in a direction perpendicular to the second connecting rod and corresponds to the middle position of the second connecting rod.

[0021] As an improved solution, the stopping mechanism further includes: a lifting positioning frame;

[0022] The lifting positioning frame is installed on the second connecting rod parallel to the second connecting rod. The bottom of the lifting positioning frame is provided with a clearance groove corresponding to the position of the stop hook.

[0029] This utility model discloses a lifting device with flexible locking. Multiple hooks connected by a scissor-link structure allow for free opening and closing of the hooks and clamping of the material frame, greatly enhancing operational flexibility. By introducing a stop hook, the opening and closing state of the hooks can be effectively controlled. When the stop hook is not engaged with the connecting rod, it ensures that the hook remains in a hooked state when the lifting ring is upward, thus safely and stably lifting the material frame. Conversely, when the stop hook is engaged with the connecting rod, the hook naturally extends under the action of the scissor-link structure, releasing the material frame and facilitating loading and unloading. Ultimately, this device simplifies the lifting operation process of the material frame, improves work efficiency, and greatly enhances operational safety and flexibility through the hook closure and stop hook locking mechanism, overcoming the shortcomings of existing technologies and possessing high application value.

[0044] Please see Figures 1-5 The embodiments of this utility model include:

[0045] A lifting device supporting flexible locking includes: a stop mechanism and a scissor linkage mechanism;

[0046] like Figure 1 As shown, the scissor linkage mechanism includes: at least two sets of first cross components that are symmetrically arranged and connected to each other, and each set of first cross components has a clamping component at its lower end.

[0048] As one embodiment of this utility model, for example... Figures 1-5 As shown, each set of first cross components includes: a pair of first lifting frames 10 that are hinged to each other. The first lifting frames 10 are in the shape of a sheet or strip and serve as the main lifting support mechanism. The two first lifting frames 10 are arranged to cross each other near their upper ends, and the two first lifting frames 10 are connected by hinges at their intersection. Of course, all the hinge methods mentioned in this article can be achieved by drilling holes at the two hinge points and hinged them to bolts, and then fixing them with hexagonal nuts 11. On this basis, the lower end of the second hinge component is connected to the upper end of the two first lifting frames 10 respectively, and the clamping component is connected to the lower end of the two first lifting frames 10. Furthermore, in order to achieve good load-bearing function, the upper and lower ends of the two symmetrical first lifting frames 10 in the two sets of first cross components are connected to each other by horizontally arranged first connecting rods 12.

[0049] As one embodiment of this utility model, for example... Figures 1-5 As shown, each group of second hinged components includes: a pair of second lifting arms 20 hinged together at their top ends; each pair of second lifting arms 20 is respectively provided corresponding to a pair of first lifting arms 10 of a group of first cross components, and the second lifting arms 20 and the first lifting arms 10 correspond one-to-one; the upper ends of the two second lifting arms 20 are hinged together, and the lower ends of the two second lifting arms 20 are respectively hinged to the upper ends of the corresponding two first lifting arms 10; more specifically, the pair of first lifting arms 10 in each group of first cross components are staggered and hinged together, each group The same applies to the pair of second lifting frames 20 in the second hinge assembly. The lower left side of one second lifting frame 20 contacts and is hinged to the right side of its corresponding first lifting frame 10, and the lower right side of the other second lifting frame 20 contacts and is hinged to the left side of its corresponding first lifting frame 10, thus forming a linkage structure. Furthermore, in order to achieve good load-bearing performance, the upper ends of the two inner second lifting frames 20 in the two sets of second hinge assemblies are connected to each other by a horizontally arranged second connecting rod 21.

[0050] As one embodiment of this utility model, for example... Figures 1-5 As shown, the stop control assembly includes: a stop hook 22 and a stop handle 23; the stop hook 22 is vertically arranged, and its upper end is rotatably connected to the middle position of the second connecting rod 21, while the lower end of the stop hook 22 is a hook groove; the stop handle 23 is connected to the side wall of the stop hook 22 in a direction perpendicular to the second connecting rod 21, and corresponds to the middle position of the second connecting rod 21; this stop hook 22 and stop handle 23 can lock the device. To cooperate with this structure to achieve the locking function, in the two sets of first cross assemblies, a horizontally arranged third connecting rod is connected between the two inner first lifting frames 10. Rod 14, the third connecting rod 14 is set at the intersection position between the two first lifting frames 10 on the same side, and the diameter of the third connecting rod 14 is set at the depth of the hook groove; based on this, when the stop hook 22 is rotated under the control of the stop handle 23 until the third connecting rod 14 is located in the hook groove, it reaches the state of hooking the third connecting rod 14, thereby locking the device. At this time, the first cross component and the second hinge component cannot move, and the first cross component and the second hinge component reach the maximum folding, that is, the clamping range of the clamping component reaches the maximum, which is suitable for alignment before lifting and unloading operation after lifting.

[0051] As one embodiment of this utility model, for example... Figures 1-5As shown, the stopping mechanism also includes: a lifting positioning frame 24; the lifting positioning frame 24 is installed parallel to the second connecting rod 21 on the upper side of the second connecting rod, and a vertical clearance groove is opened at the bottom of the lifting positioning frame 24 corresponding to the position of the stop hook 22. A lifting ring 25 is integrally connected to the top of the lifting positioning frame 24 corresponding to the position of the stop hook 22. The lifting ring 25 is used for aligning and connecting the lifting equipment, and the hook of the lifting equipment can pass through the lifting ring 25 to lift the device.

[0052] As one embodiment of this utility model, for example... Figures 1-5 As shown, the clamping assembly includes: a plurality of hooks 13; the number of hooks 13 matches the number of the first lifting frame 10, which is 4 in this embodiment; in addition, the hooks 13 are arranged one-to-one with the first lifting frame 10, and the hooks 13 are vertically connected to the lower outer side of the first lifting frame 10. In order to facilitate clamping the logistics frame 15, the two hooks 13 in the same group of first cross components are arranged facing each other; in order to have strong equipment rigidity and stability, the first lifting frame 10 and the hooks 13 corresponding to the first lifting frame 10 are integrally molded.

[0053] As one embodiment of this utility model, for example... Figures 2-5 As shown, the working principle of this device is as follows:

[0054] (1) such as Figure 2 As shown, the device is in a locked state at this time, the third connecting rod 14 is located in the hook groove of the stop hook 22, and the first cross component and the second hinge component cannot move. At this time, the device is ready to be aligned with the logistics frame 15.

[0055] (2) such as Figure 3 As shown, the device is now aligned with the logistics frame 15, ready for unlocking and lifting.

[0056] (3) such as Figure 4 As shown, when the stop handle 23 is lifted upwards, the third connecting rod 14 disengages from the hook groove of the stop hook 22. At this time, the device is in the unlocked state, and the first cross component and the second hinge component can move together, ready for lifting.

[0057] (4) such as Figure 5 As shown, at this time, the lifting hook of the lifting equipment hooks the lifting ring 25 and lifts it upward. Through the linkage between the first cross component and the second hinge component, this device can enable the four hooks 13 to directly clamp and hook the large logistics frame 15, and can adapt to all sizes of logistics frames 15 within the maximum clamping range of the hooks 13, thus having high applicability.
