[0001] This application relates to the field of hoisting equipment technology, and in particular to a hoisting device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the production scale and demand for power battery modules are increasing. During the production, assembly, and handling of battery modules, hoisting equipment is usually used to grab, move, and position the battery modules in order to improve production efficiency and reduce the labor intensity of workers.

[0003] In existing technologies, lifting devices for handling battery modules typically employ vacuum suction cups. These suction cups use negative pressure to grip and lift the battery modules quickly. However, due to the significant weight of the battery modules and the fact that surface flatness and cleanliness can affect the suction effect, situations may arise during actual production operations where the suction cups fail to hold firmly, the vacuum system suddenly malfunctions, or leaks unexpectedly, leading to the battery modules falling. Such incidents not only damage the battery modules and increase production costs, but more seriously, they can pose safety risks to personnel and damage equipment, severely impacting production safety and efficiency.

[0028] In this application, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] See Figure 1 This application provides a hoisting device, including a hanger 1, an adsorption element 4, and a receiving element 2. The adsorption element 4 is connected to the hanger 1, and the receiving element 2 is movably connected to the hanger 1. The receiving element 2 is at least partially and selectively movable below the adsorption element 4 and is disposed opposite to the adsorption element 4. The receiving element 2 is used to receive the material adsorbed by the adsorption element 4.

[0032] In practical applications, the hanger 1 is equipped with multiple adsorption components 4 along its length, which are specifically designed to adsorb materials. Taking the battery module in this embodiment as an example, the multiple adsorption components 4 can precisely correspond to and adsorb multiple battery modules, thereby achieving efficient lifting operations. The movable connection design of the receiving component 2 ensures that the receiving component 2 can be flexibly adjusted in different positions. During adsorption, the receiving component 2 can move (move or rotate) away from the hanger 1 to avoid obstructing the adsorption of the battery module by the adsorption component 4. After adsorption is completed, the receiving component 2 can move (move or rotate) closer to the hanger 1 until the receiving component 2 is at least partially located below the adsorption component 4 and is positioned opposite the adsorption component 4 along the lifting direction. At this time, the receiving component 2 is at least partially located directly below the battery module. With this configuration, when the adsorption of the adsorption component 4 fails and the battery module falls, the receiving component 2 can catch the battery module in time to prevent damage or safety accidents, ensuring the safety and reliability of the lifting process.

[0033] It should be noted that the movable connection method of the receiving component 2 can be flexibly designed according to actual needs. It can be a rotating connection between the receiving component 2 and the hanger 1, or a sliding connection between the receiving component 2 and the hanger 1. The above-mentioned relative arrangement of the receiving component 2 and the adsorption component 4 means that, along the lifting direction, the projection surface of the receiving component 2 at least partially overlaps with the projection surface of the adsorption component 4, ensuring that the receiving component 2 can effectively support the battery module at any lifting angle, avoiding accidents caused by adsorption failure.

[0034] Understandably, the adsorption component 4 is connected to an external negative pressure device, which uses the negative pressure effect to stabilize the adsorption battery module, thereby ensuring the stability of the entire hoisting process.

[0035] See Figure 2 and Figure 3 The receiving component 2 includes a connecting part 21, which is rotatably connected to the hanger 1. The connecting part 21 includes a first part 211, a second part 212, and a third part 213. One end of the second part 212 is connected to the first part 211, and the other end is connected to the third part 213. The third part 213 is rotatably connected to the hanger 1. Along the lifting direction of the hanger 1, the extension direction of the second part 212 is parallel to the lifting direction, and the extension direction of the first part 211 is perpendicular to the lifting direction. The first part 211 is bent towards the adsorption component relative to the second part 212. The first part 211 is located below the adsorption component 4 and is disposed opposite to the adsorption component 4.

[0036] In practical applications, the connecting part 21 and the hanger 1 are combined by a rotating connection. When not being lifted, the connecting part 21 can rotate outward to avoid operational interference; when being lifted, it rotates inward to ensure that the first part 211 is accurately placed under the battery module to achieve effective support.

[0037] Meanwhile, the extension directions and relative positions of the first part 211, the second part 212, and the third part 213 ensure that the connecting part 21 remains stable during rotation. In the receiving state, the extension direction of the second part 212 is parallel to the lifting direction, allowing it to fit tightly against the hanger 1. This reduces the distance between the hanger 1 and the receiving part 2, saving valuable lifting space, and provides additional support to the battery module through closer contact, further enhancing the stability of the lifting. The extension direction of the first part 211 is perpendicular to the lifting direction. When the connecting part 21 rotates smoothly to the receiving state, the first part 211 is parallel to the hanger 1, ensuring that it can completely cover the area under the battery module, thereby further expanding the receiving area and significantly improving the safety of the lifting. In addition, the rotating connection design of the third part 213 makes the connecting part 21 flexible and stable during rotation, ensuring that the receiving part 2 always maintains the optimal relative position with the battery module at different lifting angles, maximizing the receiving effect and further ensuring the reliability and safety of the lifting process.

[0038] In one embodiment, the first part 211, the second part 212 and the third part 213 can be rotatably connected in sequence. When not hoisted, the positions of the three parts can be adjusted by rotation so that they can be folded together, making them easy to store and reducing the size of the device.

[0039] See again Figure 3 The receiving component 2 includes a receiving part 22. The receiving part 22 is connected to the side of the first part 211 facing the adsorption component 4. The receiving part 22 extends along the length direction of the hanger 1 and is used to receive the material adsorbed by the adsorption component 4.

[0040] In practical applications, the receiving part 22 is a long strip structure with a length similar to that of the hanger 1. The receiving part 22 is connected to the side of the first part 211 facing the battery module, ensuring that during the hoisting process, the receiving part 22 can be completely located at the bottom of all battery modules, ensuring that the receiving part 22 can support battery modules that fall from any position, effectively preventing damage or accidents caused by accidental detachment of battery modules.

[0041] See again Figure 3 The receiving component 2 also includes a reinforcing part 23, which extends along the length of the lifting frame 1. Multiple connecting parts 21 are typically provided, spaced apart sequentially along the length of the lifting frame 1. The reinforcing part 23 connects these multiple connecting parts 21, forming a unified whole. This allows the rotation of one connecting part 21 to drive the rotation of all connecting parts 21 together, saving operation time and labor costs. Simultaneously, it ensures coordinated movement of all connecting parts 21, further improving the overall stability and operational efficiency of the lifting system. The design of the reinforcing part 23 also enhances the structural strength of the connecting parts 21, effectively distributing pressure during lifting and preventing localized overload.

[0042] See Figure 4 and Figure 5 The hoisting device includes a flexible component 6, and the adsorption component 4 is connected to the flexible component 6. The flexible component 6 is used to clamp between the adsorption component 4 and the material.

[0043] In practical applications, the flexible component 6 can be made of soft and elastic materials, such as rubber or silicone, to ensure that it can closely adhere to the material surface during clamping without causing damage to the material. The design of the flexible component 6 allows it to adapt to materials of different shapes and sizes, enhancing the adsorption stability of the adsorption component 4 and further improving the flexibility and safety of lifting operations.

[0044] See Figure 6 The flexible component 6 has a negative pressure channel 61, which is connected to the adsorption hole of the adsorption component 4.

[0045] In practical applications, the adsorption component 4 can firmly adsorb the battery module through the negative pressure channel 61, ensuring that the battery module will not slip during hoisting. The connectivity of the negative pressure channel 61 ensures a uniform distribution of adsorption force, further improving adsorption stability, effectively preventing hoisting accidents caused by weak adsorption, and ensuring operational safety. The negative pressure channel 61 can be located in the middle of the flexible component 6, or the flexible component 6 can be arranged around the negative pressure channel 61. The negative pressure channel 61 occupies a large area of ​​the flexible component 6, ensuring that the adsorption force covers a large surface area of ​​the battery module.

[0046] See again Figure 6 There are multiple flexible components 6, which are spaced apart, and an avoidance space 62 is formed between two adjacent flexible components 6.

[0047] In practical applications, the spaced arrangement of multiple flexible components 6 not only increases the coverage area of ​​the adsorption surface but also effectively avoids obstacles during hoisting, such as explosion-proof valves or terminals on the battery module. By incorporating these valves or terminals into the clearance space 62, direct contact between the flexible components 6 and the adsorption components 4 is prevented from generating strong adsorption forces on the valves or terminals, thus preventing them from detaching and ensuring the structural integrity and safety of the battery module. The design of the clearance space 62 makes hoisting operations more flexible, reduces potential damage to the battery module, and further improves the reliability and stability of the hoisting process.

[0048] See again Figure 5 The hoisting device includes an insulating component 5, which is clamped between a flexible component 6 and an adsorption component 4. The insulating component 5 has a through hole 51, which connects to a negative pressure channel 61 and an adsorption hole.

[0049] In practical applications, to ensure that the adsorption component 4 can firmly adsorb the battery module, the thickness of the flexible component 6 is usually not very thick to avoid affecting the adsorption effect of the adsorption component 4. Simultaneously, during the adsorption process, the flexible component 6 may be compressed into a thin sheet by the adsorption component 4 and the battery module, or if the flexible component 6 is damaged, the battery module may directly contact the adsorption component 4 through the negative pressure channel 61, causing a short circuit. The presence of the insulating component 5 effectively prevents direct electrical connection between the battery module and the adsorption component 4, ensuring the safety of the hoisting process. The insulating component 5 is made of a high-insulation material, such as polytetrafluoroethylene (PTFE). The insulating component 5 has perforations 51, which neither affect the connectivity of the negative pressure channel 61 nor prevents short circuits, thus improving the reliability and stability of the overall hoisting system.

[0050] See again Figure 5 A portion of the insulating member 5 extends toward the flexible member 6 to form a protrusion 52, and the flexible member 6 is connected to the protrusion 52.

[0051] In practical applications, the protrusion 52 of the insulating component 5 extends towards the battery module. The protrusion 52 can effectively support the flexible component 6, prevent it from being excessively deformed during hoisting, and provide a position for the flexible component 6 to be installed and positioned, so that the flexible component 6 can be installed quickly and accurately, ensuring a uniform distribution of the adsorption force.

[0052] At the same time, a clearance space 62 is also formed between the two adjacent protrusions 52 to avoid the terminal posts and explosion-proof valves on the battery module, thereby avoiding the interference of the adsorption component 4 on these key components and ensuring the structural safety of the battery module during hoisting.

[0053] See Figure 7 The hoisting device includes a suspension component 7, a first hook 8, a second hook 9, and a third hook 3. The first hook 8 and the second hook 9 are respectively connected to opposite sides of the suspension component 7. The third hook 3 is connected to the lifting frame 1. Along the lifting direction of the lifting frame 1, the projection plane of the second hook 9 and the projection plane of the third hook 3 at least partially overlap. The first hook 8 is used to connect to the hoist.

[0054] In practical applications, a hoisting rope is typically used to lift the gantry 1. This method results in an angle between the hoisting rope and the gantry 1, causing the gantry 1 to be subjected to bending moment during lifting, which can lead to deformation or damage. To address this, this application designs a suspension component 7. A second hook 9 is connected to the side of the suspension component 7 facing the gantry 1, and a first hook 8 is connected to the side facing away from the gantry 1. The first hook 8 is used to connect to the hoisting rope of the hoist. The second hook 9 is connected to a third hook 3 on the gantry 1. Specifically, the second hook 9 and the third hook 3 are vertically connected by a hoisting rope. This design ensures that the tension of the hoisting rope is vertically transmitted to the gantry 1, preventing the gantry 1 from being subjected to bending moment.

[0055] See again Figure 7 The suspension component 7 includes a vertical part 71 and a horizontal part 72. Along the length of the hanger 1, multiple vertical parts 71 are connected at intervals to the horizontal part 72. A second hook 9 is connected to the side of the vertical part 71 facing the hanger 1, and a first hook 8 is connected to the side of the horizontal part 72 away from the hanger 1.

[0056] In practical applications, the horizontal part 72 extends along the length of the hanger 1, and multiple vertical parts 71 are connected at intervals above the horizontal part 72. The vertical parts 71 are mainly used to connect the second hook 9, and the horizontal part 72 is mainly used to connect the first hook 8. This design ensures that the first hook 8 and the second hook 9 are subjected to opposite forces, thereby canceling out the forces on both sides of the suspension component 7 and preventing deformation and damage to the suspension component 7. The connection between the horizontal part 72 and the vertical parts 71 can be fixed by welding or other methods.

[0057] Unlike existing technologies, this application provides a lifting device including a lifting frame 1, an adsorption element 4, and a receiving element 2. The adsorption element 4 is connected to the lifting frame 1, and the receiving element 2 is movably connected to the lifting frame 1. The receiving element 2 is at least partially and selectively movable below the adsorption element 4 and is positioned opposite to the adsorption element 4. The receiving element 2 is used to receive the material adsorbed by the adsorption element 4. During the lifting process, the movable connection of the receiving element 2 allows it to be positioned below the material, ensuring that the material will not fall from the lifting device and improving the safety performance of the lifting operation.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0060] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
