[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, they should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, unless otherwise stated, "multiple" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist; for example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0053] In the accompanying drawings of this application's embodiments, arrows labeled X represent the first direction X, and arrows labeled Y represent the second direction Y. The description of this application introduces the first direction X and the second direction Y to more clearly illustrate the structure and relative positional relationship of the lifting fixture. In practical applications, the first direction X and the second direction Y can point to any direction in space. For ease of understanding, this application uses the first direction X as the guiding direction of the guide member 210 and the second direction Y as the gravity direction as an example for explanation. In practical applications, the first direction X and the second direction Y are perpendicular to each other.

[0054] In the handling and installation of electrical components (500) in industrial production, forklifts and manual labor have long dominated, but a series of drawbacks have gradually become apparent. On the one hand, manual handling not only consumes a lot of physical strength and has very low work efficiency, but also, due to over-reliance on human experience and operation, it is very easy for resistors to fall off during the handling process, causing damage to the components and, in severe cases, production stoppages. On the other hand, electrical components (500) are diverse in type and specifications, and their installation locations and required space vary greatly, making it difficult for existing handling technologies to be widely adaptable to various types of electrical components (500).

[0055] Taking the crowbar resistor of a wind power converter as an example, its installation location is either on top of the unit or in the middle of the grid-connected cabinet. Due to the diverse specifications of components in the unit, the installation location and available space also vary. Currently, the handling of crowbar resistors still relies on forklifts or manual labor. This method is not only time-consuming and labor-intensive, but also carries risks such as improper placement or falling. Once a problem occurs, it is necessary to re-handle and reinstall, seriously affecting the project delivery schedule. Furthermore, in the handling of various types of products such as photovoltaic inverters and industrial control cabinets, the existing handling methods are also difficult to balance product characteristics and installation requirements, failing to achieve efficient and safe handling.

[0056] According to the first aspect of this application, Figure 1 and Figure 2 As shown, this application provides a lifting fixture, which includes a lifting frame 100 and a clamping assembly 200. The clamping assembly 200 includes a guide member 210, a first clamping member 220, a second clamping member 230, and a driving member 240. The guide member 210 is connected to the lifting frame 100 by a secure connection. The first clamping member 220 and the second clamping member 230 are arranged on the guide member 210 along a first direction X. The driving member 240 is disposed on the guide member 210 and connected to the first clamping member 220. The driving member 240 is used to drive the first clamping member 220 to move relative to the second clamping member 230. The guide member 210 is provided with a plurality of first positioning portions 211 along the first direction X. The driving member 240 is capable of moving on the guide member 210 along the first direction X. The driving member 240 is provided with a second positioning portion 241, which is used to cooperate with the first positioning portion 211 to fix the driving member 240 on the guide member 210.

[0057] It should be noted that the hanger 100, as the key connecting hub of the entire fixture, is connected at one end to external lifting equipment such as overhead cranes or hoists, and at the other end to the guide member 210 of the clamping assembly 200, thus establishing a complete lifting system that allows the fixture to carry out handling operations with the help of external equipment. During handling, the hanger 100 evenly distributes the pulling force of the lifting equipment to the guide member 210, maintaining the balance of force on the entire fixture and preventing the electrical component 500 from tilting, shaking, or even falling due to uneven force. At the same time, through its connection with the guide member 210, the hanger 100 can indirectly control the spatial position and posture of the clamping assembly 200. For example, when the electrical component 500 is installed in a high position or in a narrow space, the hanger 100 can adjust its angle and height to allow the clamping assembly 200 to smoothly reach the designated position, greatly enhancing the flexibility and adaptability of the fixture in the handling and installation process.

[0058] It should be noted that the guide component 210 is connected to the hanger 100 via a robust connection, providing reliable support for other components and serving as the guiding hub for the entire clamping action. The guide component 210 and the hanger 100 are connected using robust methods such as welding, bolting, pinning, snap-fitting, and combination connections. Notably, the guide component 210 can be a linear guide. The linear guide, with its high-precision sliding characteristics, provides stable and accurate guidance for the movement of the first clamping component 220, the second clamping component 230, and the drive component 240, greatly improving the smoothness of the clamping assembly 200's operation.

[0059] It should be noted that the first clamping member 220 and the second clamping member 230 are arranged along the first direction X on the guide member 210, jointly undertaking the task of clamping the target electrical device 500. The driving member 240 is mounted on the guide member 210 and connected to the first clamping member 220. When it is necessary to clamp a certain electrical device 500, the driving member 240 will adjust the distance between the first clamping member 220 and the second clamping member 230, thereby achieving stable clamping of the electrical device 500. The guide member 210 is provided with a plurality of first positioning parts 211 along the first direction X, and the second positioning parts 241 on the driving member 240 correspond to them. The driving member 240 can move freely along the first direction X on the guide member 210. When it moves to a suitable position, the second positioning part 241 cooperates with the corresponding first positioning part 211 to fix the driving member 240 on the guide member 210. This allows the lifting fixture to be adapted to various types of electrical devices 500.

[0060] Through the above technical solutions, this embodiment improves the traditional handling and installation methods from multiple dimensions. From an operational perspective, the connection between the hanger 100 and external lifting equipment, along with the precise control of the clamping assembly 200, greatly simplifies the handling and installation process of the electrical component 500, reduces manual intervention, and significantly improves work efficiency. Regarding safety, the even distribution of lifting force by the hanger 100 and the stable clamping of the electrical component 500 by the clamping assembly 200 effectively prevent safety accidents such as component damage or falling due to uneven force or unstable clamping, comprehensively ensuring the safety of handling and installation operations. In terms of adaptability, the design of the first positioning part 211 on the guide 210 and the second positioning part 241 on the drive 240, combined with various connection methods, allows the fixture to be flexibly adjusted to easily handle various specifications and installation positions of the electrical component 500, solving the industry problems of laborious, inefficient, and poorly adaptable traditional forklift or manual handling, and providing a more efficient, safer, and more versatile solution for the handling and installation of industrial electrical components 500.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, to construct a refined positioning system, the guide member 210 has a plurality of first positioning holes 2111 regularly distributed on one side along the first direction X. The first positioning holes 2111 are part of the first positioning portion 211. Correspondingly, the drive member 240 is provided with a second positioning portion 241, which includes a first positioning pin 2411. When the drive member 240 moves to the appropriate position along the first direction X of the guide member 210 according to the specifications of the electrical device 500 to be clamped, the first positioning pin 2411 can be tightly embedded in the corresponding first positioning hole 2111. With the tight fit between the pin and the hole, a reliable mechanical locking structure is formed, which securely fixes the drive member 240 to the guide member 210. This positioning method not only effectively prevents the drive component 240 from shifting during transportation, ensuring that the first clamping component 220 and the second clamping component 230 always maintain a stable clamping distance, thereby reliably clamping various electrical components 500, but also has significant advantages such as simple structure, high positioning accuracy, and convenient operation, further enhancing the adaptability of the hoisting fixture to complex transportation and installation scenarios.

[0062] It is understandable that, such as Figure 3 and Figure 4As shown, the linear guide rail, acting as a guide component 210, has multiple first positioning holes 2111 distributed at precise intervals along its side along the first direction X, according to the actual needs of handling and clamping operations. Each first positioning hole 2111 is part of the first positioning portion 211. Correspondingly, the drive component 240 has a second positioning portion 241, which includes a first positioning pin 2411. The dimensions of the first positioning pin 2411 are precisely designed to form a precise tolerance fit with the first positioning holes 2111. When the drive component 240 slides to the appropriate position along the first direction X of the linear guide rail based on the specifications and shape of the electrical component 500 to be handled, the first positioning pin 2411 can be inserted into the corresponding first positioning hole 2111 manually or through an automated mechanical device. This nested fit constructs a reliable mechanical locking structure, effectively preventing displacement of the drive component 240 during lifting and ensuring that the first clamping component 220 and the second clamping component 230 maintain a stable clamping distance, thus achieving a secure clamping of the electrical component 500.

[0063] Through the above technical solutions, the jig achieves further improvements in adaptability, safety, and operational efficiency. Regarding adaptability, for electrical components 500 of various specifications and shapes, the jig can quickly adjust to the optimal clamping state by utilizing the flexible cooperation between the first positioning hole 2111 on the linear guide rail and the first positioning pin 2411 of the drive component 240, easily handling complex handling and installation scenarios. In terms of safety, the accurately nested first positioning pin 2411 and first positioning hole 2111 construct a robust mechanical locking structure, effectively preventing displacement of the drive component 240 during lifting, ensuring reliable clamping of the clamping assembly 200, and preventing damage to the electrical component 500 due to shaking or falling during handling. From an operational efficiency perspective, this positioning method is not only simple to operate but also accurate in positioning, significantly reducing the time spent adjusting the clamping position and lowering the degree of manual intervention. Combined with automated mechanical devices, it further achieves high efficiency and automation in handling and installation operations, comprehensively solving the problems of poor adaptability, low efficiency, and high safety risks inherent in traditional forklift or manual handling and installation.

[0064] In some embodiments, such as Figure 4 As shown, to construct a more refined positioning system, the guide member 210, along the first direction X, also has a second positioning hole 2112 in the first positioning part 211. The second positioning hole 2112 is located on the side of the guide member 210 opposite to the first positioning hole 2111. The second positioning part 241 also includes a second positioning pin 2412, which is located on the side of the guide member 210 away from the first positioning pin 2411. The second positioning pin 2412 can be embedded in the second positioning hole 2112 to fix the drive member 240 to the guide member 210.

[0065] It should be noted that, along the first direction X, on one side of the linear guide rail, multiple first positioning holes 2111 are distributed at precise intervals according to the actual needs of handling and clamping operations. Each first positioning hole 2111 is part of the first positioning section 211. Simultaneously, on the other side of the linear guide rail opposite to the first positioning holes 2111, multiple second positioning holes 2112 are also arranged at corresponding intervals along the first direction X. These second positioning holes 2112 are also part of the first positioning section 211. Correspondingly, the drive member 240 is provided with a second positioning section 241. A first positioning pin 2411 is installed on the side of the drive member 240 near the first positioning holes 2111; a second positioning pin 2412 is installed on the other side of the drive member 240 away from the first positioning pin 2411. The dimensions of both the first positioning pin 2411 and the second positioning pin 2412 are precisely designed to form a precise tolerance fit with the first positioning holes 2111 and the second positioning holes 2112, respectively. Understandably, when the drive component 240 slides along the first direction X of the linear guide to the appropriate position based on the specifications and shape of the electrical device 500 to be transported, the first positioning pin 2411 and the second positioning pin 2412 can be simultaneously embedded into the corresponding first positioning hole 2111 and second positioning hole 2112 with the help of manual operation or automated mechanical device. This double-sided positioning nesting cooperation method constrains the drive component 240 from two directions, constructing a more stable and reliable mechanical locking structure.

[0066] Through the above technical solution, compared with single-sided positioning, double-sided positioning not only further prevents displacement and skew of the drive component 240 during hoisting, ensuring that the first clamping component 220 and the second clamping component 230 always maintain a stable clamping distance and achieve a firm clamping of the electrical component 500, but also greatly enhances the stability of the fixture when dealing with complex working conditions such as vibration and impact. At the same time, this design significantly improves positioning accuracy and broadens the fixture's adaptability to electrical components 500 of different sizes, weights, and shapes. When handling electrical components 500 of various specifications, with the dual cooperation of the first positioning pin 2411 and the first positioning hole 2111, and the second positioning pin 2412 and the second positioning hole 2112, the fixture can quickly adjust to a suitable clamping state, further improving the efficiency and safety of handling operations and meeting the stringent requirements of modern industrial production for efficient, stable, and safe handling.

[0067] In some embodiments, such as Figure 2 , Figure 3 , Figure 5As shown, the drive member 240 includes a first mounting base 242. The first mounting base 242 has at least one third positioning hole 2421 on the side near the first positioning hole 2111. A first positioning pin 2411 can be fitted into one third positioning hole 2421 and one first positioning hole 2111 to fix the drive member 240 onto the guide member 210. The first mounting base 242 has at least one fourth positioning hole 2422 on the side near the second positioning hole 2112. A second positioning pin 2412 can be fitted into one fourth positioning hole 2422 and one second positioning hole 2112 to fix the drive member 240 onto the guide member 210.

[0068] It should be noted that the first mounting base 242 is designed with full consideration of the actual needs of handling and installing different industrial electrical components 500, and is carefully laid out around positioning and fixing functions. At least one third positioning hole 2421 is provided on the side of the first mounting base 242 near the first positioning hole 2111 of the linear guide rail. The corresponding first positioning pin 2411 can be tightly embedded in the corresponding third positioning hole 2421 and the first positioning hole 2111. When the driving component 240 slides along the linear guide rail to the appropriate position according to the specifications, center of gravity distribution, and other parameters of the electrical component 500 to be transported, the first positioning pin 2411 forms a stable mechanical connection between the first mounting base 242 and the linear guide rail through a through-embedding method, effectively preventing the driving component 240 from shifting along the first direction X during handling, and ensuring the positional accuracy of the first clamping component 220 during hoisting.

[0069] Similarly, at least one fourth positioning hole 2422 is provided on the side of the first mounting base 242 near the second positioning hole 2112 of the linear guide. The design of the second positioning pin 2412 is adapted to the fourth positioning hole 2422 and the second positioning hole 2112, and can be embedded in the corresponding fourth positioning hole 2422 and the second positioning hole 2112. This design further enhances the reliability of the drive component 240, especially when handling electrical components 500 with a shifted center of gravity or irregular shape. The cooperation between the second positioning pin 2412 and the fourth and second positioning holes 2112 constrains the drive component 240 from another side, preventing the drive component 240 from tilting due to uneven force, and ensuring the stable operation of the entire clamping assembly 200.

[0070] When handling lightweight electrical components 500 with relatively uniform dimensions and low positioning accuracy requirements, only one third positioning hole 2421 needs to be provided on the side of the first mounting base 242 near the first positioning hole 2111. The handling requirements can be met by clamping the first positioning pin 2411 with the third positioning hole 2421 and the first positioning hole 2111. However, when handling large, heavy electrical components 500 in complex operating environments, multiple third positioning holes 2421 and fourth positioning holes 2422 can be linearly arranged on both sides of the first mounting base 242 near the first positioning hole 2111 and the second positioning hole 2112, and multiple first positioning pins 2411 and second positioning pins 2412 can be provided. Multiple first positioning pins 2411 and second positioning pins 2412 are simultaneously embedded in the corresponding positioning holes. By increasing the connection points, a stable constraint system with multiple connection points on both sides is constructed, which greatly improves the stability of the connection between the drive component 240 and the guide component 210, enabling it to effectively resist strong vibration and high impact during hoisting, and meet the stringent requirements for handling and installation of industrial electrical components 500 under various complex working conditions.

[0071] In some examples, a single locating pin and single hole clamping configuration is implemented when handling lightweight electrical components 500 with relatively uniform dimensions and where positioning accuracy requirements are not high. The first mounting base 242, near the first locating hole 2111 on the linear guide, has only one third locating hole 2421. The first locating pin 2411 can be inserted into the corresponding third locating hole 2421 and the first locating hole 2111. After the driving component 240 slides along the linear guide to the appropriate position, the first locating pin 2411, through its insertion, forms a clamping fixation, securing the driving component 240 to the guide component 210 and preventing displacement of the driving component 240 during handling.

[0072] In some examples, where multiple locating pins are densely arranged, if the electrical component being transported is heavy and the operating environment is complex, requiring extremely high stability, multiple third locating holes 2421 are provided on the side of the first mounting base 242 near the first locating hole 2111, arranged linearly. Correspondingly, multiple first locating pins 2411 are provided. After the driving component 240 moves to the designated position, the multiple first locating pins 2411 simultaneously engage with the corresponding third locating holes 2421 and first locating holes 2111, significantly increasing the number of connection points, enhancing the reliability of the fixation, and effectively resisting the impact and vibration caused by heavy lifting and complex environments.

[0073] In some examples, dual-sided independent positioning is implemented. When handling irregularly shaped electrical components 500 with a shifted center of gravity, dual-sided positioning is required to ensure clamping stability. The first mounting base 242, near the second positioning hole 2112 of the linear guide, has at least one fourth positioning hole 2422. The second positioning pin 2412 can be inserted into the corresponding fourth positioning hole 2422 and second positioning hole 2112. In actual operation, the first positioning pin 2411 engages with the third and first positioning holes 2111 to initially fix the position of the drive component 240. Then, the second positioning pin 2412 engages with the fourth and second positioning holes 2112 to position the drive component 240 from the other side. The dual-sided independent positioning works synergistically to prevent the drive component 240 from tilting due to uneven force, ensuring the stability of the electrical component 500 during handling.

[0074] In some examples, a double-sided multi-positioning pin dense fixing scheme is required when handling large electrical components 500 with complex center of gravity distribution and near-stringent stability requirements. On the side of the first mounting base 242 near the first positioning hole 2111 of the linear guide rail, multiple third positioning holes 2421 are linearly arranged along the first direction X. Simultaneously, on the side near the second positioning hole 2112, multiple fourth positioning holes 2422 are also linearly distributed. Correspondingly, multiple first positioning pins 2411 and second positioning pins 2412 are provided. After the driving member 240 moves to the predetermined position, the multiple first positioning pins 2411 synchronously engage with the corresponding third positioning holes 2421 and first positioning holes 2111, and the multiple second positioning pins 2412 synchronously engage with the corresponding fourth positioning holes 2422 and second positioning holes 2112. This double-sided, multi-connection-point fixing method provides a stable constraint on the drive component 240 from two directions, greatly improving the stability of the connection between the drive component 240 and the guide component 210. Even if strong vibrations or high impacts occur during hoisting, it can prevent the drive component 240 from shifting or tilting, ensuring that the first and second clamping components 230 stably clamp the electrical component 500, avoiding the risk of falling due to unstable center of gravity, and meeting the needs of high-difficulty handling operations.

[0075] Through the above technical solution, the first positioning pin 2411 and the second positioning pin 2412 respectively cooperate with the corresponding positioning holes to construct a double-safety positioning mechanism. This mechanism not only ensures that the first clamping member 220 and the second clamping member 230 always maintain a stable clamping distance and reliably clamp various electrical components 500, but also greatly improves the stability and adaptability of the fixture under complex working conditions, enabling the fixture to quickly adjust the clamping state, significantly improve handling efficiency, reduce safety risks, and provide a better solution for the handling and installation of industrial electrical components 500.

[0076] In some embodiments, such as Figure 2 and Figure 3As shown, the functionality and practicality of the drive component 240 are further enhanced. In addition to the first mounting base 242, it also includes a first sliding part 243. One side of the first sliding part 243 is slidably connected to the guide component 210, and the other side is connected to the first mounting base 242.

[0077] It should be noted that the first sliding part 243 is made of high-strength, low-friction engineering plastics or self-lubricating alloys, which reduces the overall weight while ensuring wear resistance during long-term use. One side of the first sliding part 243 has a groove or slider structure adapted to the linear guide rail, achieving a smooth sliding connection with the linear guide rail of the guide member 210. This ensures that the drive member 240 can move smoothly along the first direction X, effectively reducing jamming and resistance during operation. The other side is tightly connected to the first mounting base 242 through welding, bolting, or mortise and tenon joints, ensuring reliable connection while ensuring that the first mounting base 242 and the first sliding part 243 work together as a cohesive unit. During handling operations, when the drive member 240 needs to be adjusted according to the specifications and installation position of the electrical component 500, the first sliding part 243 can, through its sliding connection with the guide member 210, drive the first mounting base 242 to quickly move to the designated position along the linear guide rail. For example, when moving electrical components 500 of different sizes, the drive component 240 can be flexibly adjusted in position by the first sliding part 243, and then the first positioning pin 2411 and the second positioning pin 2412 are respectively embedded in the corresponding positioning holes to fix the drive component 240.

[0078] Through the above technical solution, the coordinated cooperation between the first sliding part 243 and the first mounting base 242 enables the lifting fixture to not only achieve rapid positioning and stable clamping when dealing with diverse handling tasks, but also significantly improves work efficiency. It effectively solves the shortcomings of traditional handling equipment in terms of positioning flexibility and handling stability, and provides a more reliable technical guarantee for the handling and installation of industrial electrical components 500.

[0079] In some embodiments, such as Figure 6 As shown, the first clamping member 220, through its meticulous modular design, significantly improves the clamping flexibility and adaptability of the lifting fixture. The first clamping member 220 includes a second sliding portion 221, a second mounting base 222, and a first clamping portion 223. The second sliding portion 221 is slidably connected to the guide member 210. The second mounting base 222 is connected to the side of the second sliding portion 221 opposite to the guide member 210, and the driving member 240 is connected to the second mounting base 222. One end of the first clamping portion 223 is connected to the second mounting base 222, and the other end is located on the side of the guide member 210 opposite to the second mounting base 222, with the first clamping portion 223 facing the second clamping member 230.

[0080] It should be noted that the second sliding part 221 is made of a special material with high wear resistance and low friction characteristics, such as polytetrafluoroethylene composite material or wear-resistant bronze alloy. Its surface is finely polished to achieve a seamless fit with the guide member 210. The second sliding part 221 is equipped with a slider or groove structure specially adapted to the linear guide rail, ensuring that the second sliding part 221 can move smoothly along the first direction X of the guide member 210 during operation, effectively reducing the jamming phenomenon caused by uneven friction and greatly improving the smoothness of the movement of the first clamping member 220.

[0081] It should be noted that the second mounting base 222 is installed on the side of the second sliding part 221 opposite to the guide member 210, and the two are fixed by welding, high-strength bolt connection, or precision tenon and mortise splicing. This connection method not only ensures the stability of the connection between the second mounting base 222 and the second sliding part 221, but also allows the second mounting base 222 and the second sliding part 221 to operate as a coordinated whole during operation. In addition, the driving member 240 is connected to the second mounting base 222. When the driving member 240 is activated, it can drive the second mounting base 222, as well as the connected second sliding part 221 and the first clamping part 223, to move according to a preset path.

[0082] It should be noted that one end of the first clamping part 223 is connected to the second mounting base 222, and the other end extends to the side of the guide member 210 away from the second mounting base 222 and towards the second clamping member 230. During the handling operation, when the driving member 240 moves the first clamping member 220 to the designated position through the second sliding part 221 according to the specifications and installation position of the electrical component 500, the first clamping part 223 and the second clamping member 230 cooperate with each other to complete the clamping action of the electrical component 500.

[0083] Through the aforementioned technical solution, the coordinated operation of the second sliding part 221, the second mounting base 222, and the first clamping part 223 greatly enhances the adaptability of the lifting fixture to electrical components 500 of different shapes, sizes, and weights. In actual handling processes, this design not only ensures efficient clamping action but also enhances the stability of the entire fixture during handling, further addressing the shortcomings of traditional handling equipment in terms of clamping flexibility and stability, and providing more reliable technical support for the handling and installation of industrial electrical components 500.

[0084] In some embodiments, such as Figure 6As shown, the first clamping part 223 includes at least one extension 2231 and a first overlapping part 2232. One end of the extension 2231 is connected to the second mounting base 222, and the other end is located on the side of the guide member 210 opposite to the second mounting base 222. The first overlapping part 2232 is disposed at the end of the extension 2231 opposite to the second mounting base 222 and faces the second clamping member 230. It should be noted that one end of the extension 2231 is connected to the second mounting base 222 by welding, high-strength bolts, or other fixing methods, providing stable support for the first clamping part 223. The other end extends to the side of the guide member 210 opposite to the second mounting base 222. A reasonable gap is reserved between the extension 2231 and the guide member 210. This gap design not only avoids component wear caused by friction and collision between the extension 2231 and the guide 210 when the extension 2231 moves along the guide 210 with the drive 240, effectively extending the service life of the extension 2231 and the guide 210, but also ensures that the extension 2231 can still make a certain degree of posture adjustment with the movement of the drive 240 within a limited space, improving the flexibility of the first clamping part 223 during the clamping process. The surface of the first overlapping part 2232 is bonded with anti-slip rubber or a serrated metal plate, which increases the friction with the surface of the electrical component 500 and prevents the electrical component 500 from sliding during handling. Its shape can be customized according to the shape of common electrical components 500, and can be designed as a planar structure or an arc structure, thereby achieving a tighter fit. Through the above technical solution, the collaborative design of the extension 2231 and the first overlapping part 2232 expands the clamping range of the lifting fixture and improves the efficiency of the clamping operation.

[0085] In some embodiments, such as Figure 6As shown, the first clamping part 223 has a first clearance groove 2233, which passes through the first overlapping part 2232 along the first direction X. It should be noted that during installation, the first clearance groove 2233 provides installers with more convenient operating space. When the first clamping part 223 is assembled with the second mounting base 222, the first clearance groove 2233 cleverly avoids part of the connecting structure, allowing installers to more easily align the installation position and enabling tools to reach the installation point more smoothly. This greatly simplifies the installation process, significantly shortens installation time, and significantly improves installation efficiency. In terms of weight reduction and improved clamping stability, the first clearance groove 2233 effectively reduces the overall weight of the first overlapping portion 2232, lowers the load on the lifting fixture, and improves energy efficiency. Furthermore, when lifting complex electrical components 500 with protruding parts, the first clearance groove 2233 cleverly avoids these protruding parts, allowing the first overlapping portion 2232 to fit more tightly against the body of the electrical component 500, thus improving clamping stability. Through this technical solution, the first clearance groove 2233 avoids some connecting structures during installation, facilitating alignment and tool operation for installers, significantly improving installation efficiency. It reduces the weight of the first overlapping portion 2232, lowers the load on the fixture, and improves energy efficiency. When lifting complex electrical components 500, the clearance groove avoids protruding parts, allowing the first overlapping portion 2232 to fit tightly against the body of the electrical component 500; combined with anti-slip rubber or serrated metal plates, it increases friction and enhances clamping stability.

[0086] In some embodiments, such as Figure 7 As shown, the second clamping member 230 includes a second clamping portion 231, which is disposed on the side of the guide member 210 opposite to the second mounting base 222 and connected to the guide member 210. The second clamping portion 231 faces the first overlapping portion 2232. It should be noted that the second clamping portion 231 and the guide member 210 can be reliably connected through welding, bolting, tenon and mortise structures, etc., to ensure that the second clamping portion 231 maintains a stable position during handling operations. The second clamping portion 231 faces the first overlapping portion 2232 as a whole, and the surface of the second clamping portion 231 can be fitted with anti-slip rubber or a serrated metal plate to increase the friction with the surface of the electrical component 500 and prevent slippage during handling.

[0087] In some examples, the second clamping part 231 and the first overlapping part 2232 form a complementary clamping scheme for electrical devices 500 of different shapes and weights. The second clamping part 231 faces the first overlapping part 2232, and its surface is fitted with anti-slip rubber or a serrated metal plate. During clamping operations, it acts laterally on the electrical device 500 from the first direction X in an abutting manner. Simultaneously, the first overlapping part 2232 provides support, offering support to the electrical device 500 through its relative positional cooperation with the second clamping part 231. Its surface is also fitted with anti-slip material to increase friction with the bottom of the electrical device 500.

[0088] Through the above technical solution, the second clamping part 231 abuts against the electrical component 500 from the side, while the first overlapping part 2232 supports it from below. The anti-slip design of both surfaces increases friction, and their shapes are customized and mutually adaptable to achieve tight clamping. Specifically, the second clamping part 231 and the first overlapping part 2232 work closely together to significantly enhance the stability of clamping various electrical components 500, effectively solving the problem that traditional handling equipment is difficult to adapt to complex-shaped electrical components 500 and that clamping is prone to loosening, thus significantly improving the safety and efficiency of lifting fixture handling.

[0089] In some embodiments, such as Figure 7 As shown, the second clamping member 230 also includes a second overlapping portion 232, which is disposed on the side of the second clamping portion 231 facing the first overlapping portion 2232 and connected to the second clamping portion 231. It should be noted that the second overlapping portion 232 can be made of a high-strength, lightweight alloy material and is fixed to the second clamping portion 231 by welding or bolting, ensuring the reliability of the connection and reducing the overall weight to some extent. The surface of the second overlapping portion 232 is covered with anti-slip rubber or a metal plate with anti-slip texture, significantly increasing the friction with the surface of the clamped electrical device 500 and preventing displacement of the electrical device 500 during handling. Its shape is specifically designed according to the structure and outline of different types of electrical devices 500, and can be in various forms such as flat or curved surfaces, matching the shape of the first overlapping portion 2232. This aims to form a tight and stable clamping of the electrical device 500 from different directions during handling operations. In practical applications, when handling electrical components 500 with relatively smooth surfaces, the second overlapping part 232 and the first overlapping part 2232 can quickly and reliably clamp the electrical components 500 by means of anti-slip materials and matching shapes, ensuring that the electrical components 500 are always in a stable state during lifting, transportation and installation, and effectively avoiding safety accidents caused by insecure clamping.

[0090] Through the above technical solution, the design of the second overlapping part 232 further enriches the function of the second clamping part 230, enhances the adaptability of the entire lifting fixture to electrical components 500 of different shapes, sizes and weights, greatly improves the flexibility and efficiency of handling operations, and provides a more complete solution for the field of industrial electrical handling.

[0091] In some embodiments, such as Figure 7 As shown, the second clamping member 230 has a second clearance groove 233, which passes through the second overlapping portion 232. It should be noted that the second clearance groove 233 can avoid part of the connecting structure during installation, allowing installers to more easily align the installation position and operate tools, improving installation efficiency. In terms of weight reduction, the second clearance groove 233 can reduce the overall weight of the second overlapping portion 232, reducing the load on the lifting jig and improving energy efficiency. When lifting electrical components 500 with complex structures and protruding parts, the second clearance groove 233 can avoid these protruding parts, allowing the second overlapping portion 232 to fit tightly against the body of the electrical component 500. Combined with the anti-slip rubber or serrated metal plate on the surface of the second overlapping portion 232, the friction with the surface of the electrical component 500 can be increased, enhancing clamping stability.

[0092] Through the above technical solution, the design of the second clearance groove 233 brings many advantages to the lifting fixture, which not only improves the installation efficiency and reduces the equipment load, but also enhances the clamping stability of complex electrical components 500, and further improves the practicality and reliability of the lifting fixture in the field of handling and installing industrial electrical components 500.

[0093] In some embodiments, such as Figure 3 and Figure 5 As shown, the drive unit 240 includes a drive part 244 mounted on the first mounting base 242, which is a positioning cylinder. Based on pneumatic transmission, compressed air is input into the cylinder to drive the piston in a linear motion, achieving positioning and driving. The positioning cylinder is securely mounted on the first mounting base 242 by bolt connection or welding, and the two work together during operation.

[0094] When it is necessary to adjust the distance between the first clamping member 220 and the second clamping member 230 to clamp electrical components 500 of different specifications, the positioning cylinder quickly and accurately drives the first mounting base 242 to move along the guide member 210 according to the control signal. The positioning cylinder has high positioning accuracy and can precisely control the position of the first clamping member 220 to ensure accurate clamping. At the same time, the fast response speed can improve the working efficiency of the lifting fixture.

[0095] The positioning cylinder features a robust structure and a stable pneumatic transmission system, capable of withstanding vibrations and impacts in industrial production. It can operate normally even under prolonged high-intensity work, reducing malfunctions. Maintenance is simple; regular checks of the pneumatic system's seals and cleaning of dust are sufficient to ensure stable performance. Furthermore, its low cost helps control equipment manufacturing costs and improves economic efficiency.

[0096] In some embodiments, such as Figure 2 As shown, the drive unit 240 also includes a collision avoidance part 245, which covers the drive unit 244 and is connected to the first mounting base 242. It should be noted that the collision avoidance part 245 and the first mounting base 242 can be connected by welding or bolts. The collision avoidance part 245 can provide a certain degree of protection for the drive unit 244, preventing it from colliding with other foreign objects or equipment during transportation or use.

[0097] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes an adjusting component 300, which is disposed on the side of the hanger 100 opposite to the guide component 210. It should be noted that in the handling and installation of industrial electrical components 500, even if the component 500 is hoisted to the preset installation position, due to factors such as manufacturing errors of the component 500 itself and deviations in the accuracy of the installation position, the component 500 and the installation position are not perfectly matched, making it difficult to directly complete precise installation. At this time, the adjusting component 300 plays a crucial role. In this embodiment, the adjusting component 300 adopts a handle structure, which can be adjusted manually.

[0098] The handle structure mainly consists of an operating handle, a transmission rod, and a connecting mechanism. The connecting mechanism securely mounts the operating handle on the side of the hanger 100 away from the guide member 210, ensuring its stability during operation. The operating handle extends to a position easily accessible to the operator for convenient direct manual operation. One end of the transmission rod is connected to the operating handle, and the other end is connected to the hanger 100, serving to transmit operating force.

[0099] When electrical component 500 is hoisted to its installation position but there is a positional deviation, the operator can directly grasp the handle to adjust it. If electrical component 500 is offset in the horizontal direction, the force is transmitted to the clamping assembly 200 through the transmission rod, causing the clamping assembly 200 to translate horizontally, thereby adjusting the position of electrical component 500 on the horizontal plane. If electrical component 500 is offset in angle, the operator can push or pull the handle, and the transmission rod will push the clamping assembly 200 to rotate at a small angle, thereby correcting the angular deviation of electrical component 500.

[0100] Once the compatibility issue between electrical component 500 and the installation location is resolved, the operator can precisely place the electrical component 500 in the installation position using the adjusting component 300 to complete the installation work. This manually adjustable handle structure makes the lifting fixture more adaptable and flexible in the face of complex and changing installation situations, improving the accuracy and efficiency of electrical component 500 installation, and reducing installation difficulties and time waste caused by mismatched positions.

[0101] Through the above technical solution, the adjusting component 300 provides an effective means of fine-tuning the position of the electrical component 500 after it is hoisted to the installation position, which enhances the practicality and reliability of the hoisting fixture in actual application and provides strong support for the installation of the industrial electrical component 500.

[0102] In some examples, the handle structure comprises an operating handle, a switch control valve, a transmission rod, and a connecting mechanism. The connecting mechanism securely mounts the operating handle to the side of the hanger 100 away from the guide member 210, ensuring stability during operation while ensuring that the handle extends to a position easily accessible to the operator for direct operation.

[0103] When hoisting operations begin, the switch control valve at the operating handle inputs compressed air into the cylinder (drive unit 244), causing the piston rod to extend and retract, thus moving the first clamping member 220 and the second clamping member 230 relative to each other. For electrical components 500 of different sizes, the cylinder can adjust the piston rod stroke to adapt the distance between the first clamping member 220 and the second clamping member 230 to the size of the electrical component 500, achieving stable clamping. Furthermore, the cylinder has a fast response and high output force, enabling it to quickly and firmly clamp the electrical component 500, preventing it from shaking or falling during handling.

[0104] When electrical component 500 is hoisted to its installation position but there is a positional deviation, the operator can directly grasp the operating handle to adjust it. If electrical component 500 is offset in the horizontal direction, the force is transmitted to the clamping assembly 200 through the transmission rod, causing the clamping assembly 200 to translate horizontally, thereby adjusting the position of electrical component 500 on the horizontal plane. If electrical component 500 is offset in angle, the operator can push or pull the handle, and the transmission rod will push the clamping assembly 200 to rotate at a small angle, thereby correcting the angular deviation of electrical component 500.

[0105] Through the above technical solution, the switch control valve at the operating handle can control the cylinder to precisely adjust the piston rod stroke according to the specifications of the electrical component 500, achieving precise clamping. The cylinder has a fast response and large output force, preventing the electrical component 500 from shaking or falling during handling, thus ensuring safe handling. When there is a deviation in the installation position of the electrical component 500, the operator can directly operate the handle and flexibly adjust the horizontal position and rotation angle of the clamping assembly 200 with the help of the transmission rod, improving installation accuracy. The connecting mechanism installs the operating handle in a place that is easy for the operator to reach, and the switch control valve is integrated into the operating handle, reducing the difficulty and intensity of operation.

[0106] In some embodiments, such as Figure 1 and Figure 2 As shown, the hanger 100 includes a support member 110, a beam 120, and a lifting component 130. The support member 110 is arranged along a second direction Y and connected to the guide member 210, the second direction Y intersecting with the first direction X. The beam 120 is located at the end of the support member 110 away from the guide member 210 and is connected to the support member 110. The lifting component 130 is mounted on the beam 120. It should be noted that the support member 110 and the guide member 210 can be reliably connected by welding, bolting, or mortise and tenon joints. The support member 110 is mostly made of high-strength steel. Its cross-sectional shape and size are determined according to the weight and size of the electrical component 500 being lifted and the overall design requirements of the fixture, such as the common I-beam or rectangular shape, to ensure stable support for the guide member 210 and the clamping assembly 200 during handling, preventing swaying or deformation due to insufficient support.

[0107] Beam 120 is located at the end of support 110 away from guide 210. The two can be connected by welding, flange connection, or high-strength bolts to ensure a tight and firm connection, so that beam 120 and support 110 form a stable whole during operation. Beam 120 can be made of high-quality alloy steel and machined to ensure the surface flatness and dimensional accuracy of beam 120, meeting the requirements of use under different working conditions.

[0108] The lifting component 130 is installed on the beam 120. The lifting component 130 can be a hook, lifting ring, etc. The connection between the lifting component 130 and the beam 120 can be fastened with bolts or welded to ensure that it will not loosen during the lifting process. In actual use, the lifting component 130 is connected to external lifting equipment such as overhead cranes or gantry cranes to transfer the pulling force of the lifting equipment to the lifting frame 100, thereby driving the entire jig and the electrical components 500 being lifted to move.

[0109] Through the above technical solution, the gantry 100, through the coordinated cooperation of the support component 110, beam 120, and lifting component 130, constructs a stable lifting system, which not only ensures the safety and stability of the lifting process, but also improves the adaptability and reliability of the lifting fixture in the handling and installation process, providing a strong guarantee for the handling and installation of industrial electrical components 500.

[0110] In some embodiments, such as Figure 1 As shown, a reinforcing member 400 is included, which is disposed at the connection between the hanger 100 and the guide member 210. It should be noted that in industrial settings, during the handling of the electrical component 500, the connection between the hanger 100 and the guide member 210 must withstand the weight of the electrical component 500, as well as vibrations and impacts generated during lifting and movement, resulting in complex stress conditions. To further improve the reliability and stability of the connection, specifically, the reinforcing member 400 is disposed at the two included angles between the guide member 210 and the support member 110, and at the included angle between the support member 110 and the beam 120.

[0111] The 400 reinforcement component is made of high-strength alloy steel and is integrally formed using a forging process. This not only ensures a dense internal structure free from defects such as porosity and sand holes, but also allows for precise control of its dimensional accuracy through machining. A common design for the 400 reinforcement component is a triangular reinforcing rib structure. This structure, thanks to the stability of a triangle, can evenly distribute stress concentrated at the connection point to all components, significantly improving the load-bearing capacity of the connection area.

[0112] At the angle between the guide member 210 and the support member 110, one end of the reinforcing member 400 is tightly fitted to the side of the guide member 210 and firmly connected by a full welding process. The weld is inspected for flaws to ensure there are no problems such as incomplete welding or detachment. The other end is welded to the surface of the support member 110 to form a stable triangular structure. At the angle between the support member 110 and the beam 120, the same full welding method is used to reliably connect the reinforcing member 400 to both.

[0113] Some reinforcement components 400 also have rubber buffer pads embedded in the surfaces that contact the parts. During handling, when the fixture is subjected to vibration or impact, the rubber buffer pads absorb and cushion some of the energy due to their elasticity, reducing damage to the connection parts and further extending the service life of the fixture.

[0114] By incorporating the aforementioned technical solution and installing reinforcing members 400 at key angles, the stability of the connection between the hanger 100 and the guide member 210 is significantly improved, effectively reducing safety risks caused by connection failures and ensuring the safety of the electrical component 500 during handling. Simultaneously, this design enhances the adaptability of the lifting fixture to harsh working environments and complex conditions, meeting the stringent requirements of industrial production for efficient and safe handling, and providing more reliable technical support for the handling and installation of industrial electrical components 500.

[0115] According to a second aspect of this application, a lifting device is provided, which includes the aforementioned lifting fixture. This lifting device possesses all the beneficial effects of the aforementioned lifting fixture, which will not be elaborated further herein.

[0116] This application exemplarily describes the working process of a lifting fixture:

[0117] The operator adjusts the clamping assembly 200 of the lifting fixture according to the size and weight of the electrical component 500 to be lifted. The position of the drive component 240 is first fixed by the cooperation of the second positioning part 241 and the first positioning part 211. Then, compressed air is input into the cylinder in the drive component 240 through the switch control valve at the operating handle. The cylinder piston rod extends or retracts, causing the first clamping component 220 and the second clamping component 230 to move relative to each other, adjusting the distance between them to match the size of the electrical component 500. Simultaneously, the connection between the reinforcing member 400 and the hanger 100 and guide member 210 is checked for stability to ensure the overall condition of the equipment is good.

[0118] Start the lifting equipment and lower the lifting jig to a suitable position above the electrical component 500. Ensure that the first clamping member 220 and the second clamping member 230 are accurately aligned with the clamping points of the electrical component 500. Then, operate the switch control valve again to drive the cylinder to clamp the electrical component 500. After confirming that the clamping is secure, slowly lift the lifting equipment and smoothly hoist the electrical component 500.

[0119] When the electrical component 500 is hoisted above the installation position, the lifting equipment slowly descends. At this time, if there is a positional deviation between the electrical component 500 and the installation position, the operator can hold the handle and make fine adjustments to the clamping assembly 200 by pushing or turning the handle, using the transmission rod. If the electrical component 500 is offset in the horizontal direction, the transmission rod will drive the clamping assembly 200 to move horizontally; if there is an angular deviation, the transmission rod will push the clamping assembly 200 to rotate at a small angle until the electrical component 500 is precisely aligned with the installation position.

[0120] After electrical component 500 is installed, the operator operates the switch control valve to control the cylinder to release clamping assembly 200. The lifting equipment then slowly lifts the hoisting fixture and leaves the installation site, preparing for the next hoisting operation. During this period, maintenance personnel can conduct routine inspections of the equipment to ensure that all components are undamaged, preparing for subsequent operations.

[0121] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

[0122] The embodiments, implementation methods, and related technical features of this application can be combined and substituted for each other without conflict.

[0123] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this application without departing from the scope of the technical solution of this application shall still fall within the scope of the technical solution of this application.
