Description

Technical Field

[0001] This invention relates to the field of hoisting technology, and in particular to a modular clamping and hoisting device for adaptive GIS components and its hoisting method. Background Technology

[0002] In the construction and maintenance of modern substations, gas-insulated fully enclosed switchgear (GIS) is widely used due to its high reliability and small footprint. However, the hoisting, transportation, and precise placement of GIS components within the limited indoor space of a substation remains a highly challenging task, and existing technologies have significant shortcomings in transportation, hoisting, and critical clamping processes.

[0003] Currently, common work methods have significant drawbacks. In indoor ground transportation, light forklifts are commonly used with simple tools such as homemade brackets. These non-standard tools suffer from structural instability and insufficient load-bearing capacity. Furthermore, in confined indoor environments with complex floor plans, forklifts have large turning radii and poor maneuverability, increasing the risk of equipment collisions. Secondly, for high-altitude installation, there is a heavy reliance on temporary lifting points set up on the factory roof structure. These temporary lifting points are not only cumbersome and time-consuming to set up, but their load-bearing capacity and stability are also difficult to guarantee, posing significant safety hazards. At the same time, they rely entirely on manual binding and hanging, lacking dedicated and reliable clamping mechanisms. During operation, wire ropes or lifting slings are often used for simple binding, which is difficult to adapt to the diverse shapes and structures of GIS components (such as busbars and switches). This can easily lead to damage to the surface coating of the components, deformation of the internal precision structure due to uneven stress, or even slippage during lifting due to insecure binding, causing serious accidents. There is a lack of adaptive adjustment and precise positioning capabilities. Components are prone to shaking and rotation during lifting, requiring repeated adjustments during positioning, resulting in low efficiency and difficulty in guaranteeing installation accuracy, failing to meet the installation requirements of modern high-precision GIS equipment. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of existing GIS component indoor hoisting, such as reliance on manual binding, low positioning accuracy, and poor adaptability to confined spaces. The invention proposes an adaptive modular clamping and hoisting device and method for GIS components. Firstly, it integrates lifting and clamping actions through mechanical linkage, reducing operational steps. Secondly, to adapt to the diverse shapes of GIS components, a multi-dimensional adaptive clamping structure is designed to avoid surface damage. Finally, mechanical locking ensures operational safety and installation accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A modular clamping and hoisting device for adaptive GIS components, including a wheeled chassis, and further comprising: A counterweight base, which is fixed on a wheeled chassis, and a control console is provided on the top of the counterweight base; The lifting unit is located on the front side of the counterweight and is used to realize the vertical lifting of the hoisting platform. The hoisting platform is connected to the output end of the lifting unit. A modular clamping component is mounted on a lifting platform for adaptive clamping of GIS components; The lifting platform includes a front fork extending in the working direction, and the modular clamping component is disposed on the front fork. When the lifting unit drives the lifting platform to rise, it can drive the modular clamping component to perform an adaptive clamping action on the GIS component placed on the front fork through a mechanical linkage mechanism.

[0006] Preferably, the lifting unit includes a bottom bracket fixed to the outside of the counterweight, a movable bracket assembly mounted on the bottom bracket, and a first hydraulic cylinder fixedly mounted on the bottom bracket. The movable bracket assembly includes at least two movable brackets, with adjacent movable brackets slidably connected. The movable bracket at the bottom of the movable bracket assembly is slidably connected to the bottom bracket, and the movable bracket at the top of the movable bracket assembly is fixedly connected to the piston rod of the first hydraulic cylinder.

[0007] Preferably, the lifting platform further includes a fixed frame fixed on the uppermost movable bracket of the movable bracket assembly, a scissor-type bracket rotatably connected to the fixed frame at one end via a pin, a second hydraulic cylinder mounted on the fixed frame for driving the scissor-type bracket to extend or retract, a mounting base rotatably connected to the end of the scissor-type bracket away from the fixed frame, a drive motor fixedly mounted on the mounting base, a rotating tube rotatably connected to the mounting base and connected to the output shaft of the drive motor, and a mounting plate fixedly connected to the rotating tube. The front fork is connected to the mounting plate, and the front fork includes a cross plate connected to the mounting plate and two fork plates fixedly mounted on the cross plate.

[0008] Preferably, the modular clamping component includes two symmetrically arranged movable frames, and the two movable frames are slidably connected to the two fork plates of the front fork component respectively; The mechanical linkage mechanism includes a pulley mounted on a mounting plate and a pull rope that passes over the pulley, with both ends of the pull rope connected to the two movable frames respectively; When the hoisting platform rises, the mounting plate moves relative to the fork supporting the GIS component, and the two moving frames slide towards each other along the fork plate by being pulled by the pull rope.

[0009] Preferably, the modular clamping component further includes a fixed base fixedly disposed on each of the movable frames, a bidirectional screw rotatably connected to the fixed base, sleeves threadedly connected to both ends of the bidirectional screw, and an adaptive clamping assembly disposed corresponding to each of the sleeves.

[0010] Preferably, the adaptive clamping assembly includes: a connecting plate fixedly connected to the fixed base, a swing plate rotatably connected to the connecting plate via a pin, a groove formed on the swing plate, a slider slidably disposed in the groove, a first elastic element disposed between the slider and the inner wall of the groove, and a push-pull rod with its two ends respectively hinged to the sleeve and the slider. When the bidirectional screw rotates and drives the two sleeves to move away from or closer to each other, the push-pull rod pushes the slider, thereby driving the swing plate to rotate around its pin, thus realizing the clamping or releasing action.

[0011] Preferably, a movable gear is fixedly provided at the end of the bidirectional screw, a rack plate that meshes with the movable gear is fixedly provided on the fork plate, and an elastic telescopic rod is provided between the movable frame and the fork plate; When the movable frame slides along the fork plate, the bidirectional screw is driven to rotate through the meshing transmission between the rack plate and the movable gear.

[0012] Preferably, the swing plate is further provided with a locking mechanism, which includes: two recessed holes on the swing plate, a sliding rod slidably disposed in the recessed holes, a second elastic element disposed between each sliding rod and the inner wall of the corresponding recessed hole, a force-bearing plate connected to the ends of the two sliding rods, a plurality of elastic telescopic inserts disposed on the force-bearing plate, and a plurality of positioning inserts disposed on the connecting plate and cooperating with the elastic telescopic inserts. A base plate that moves against the force-bearing plate is fixedly disposed on the mounting plate.

[0013] Preferably, the swing plate is further provided with an auxiliary clamping component for assisting in clamping the GIS component. The auxiliary clamping component includes a telescopic swing rod that is rotatably connected to the end of the swing plate away from the connecting plate via a pin, and a connecting rod that is hinged between the end of the telescopic swing rod and the sleeve.

[0014] This invention also discloses a method for hoisting an adaptive GIS component, which involves using the aforementioned modular clamping and hoisting device for the adaptive GIS component to perform the hoisting operation, including the following steps: S1: The operator moves the driving device so that the two forks of the front fork of the lifting platform extend under the GIS component to be lifted and support the GIS component. S2: Activate the first hydraulic cylinder of the lifting unit to push the movable support assembly to extend, thereby driving the entire lifting platform to rise; Due to the enormous weight of the GIS components, initially, the fork lags behind due to the load, while the mounting plate rises first along with the main body of the lifting platform. This relative displacement causes the pulleys on the mounting plate to lift, pulling the ropes that go around them. The two ends of the ropes pull two moving frames to slide towards each other along the fork plate. When the moving frames slide, the movable gears fixed on them roll along the rack plates fixed on the fork plate, converting the linear motion into the rotational motion of the bidirectional screw. The bidirectional screw rotates and drives the sleeves at both ends to move away from each other. The movement of each sleeve is driven by the push-pull rod to push the slider: In the initial stage, the force directly pushes the swing plate to rotate around the hinge point between it and the connecting plate through the slider, so that the swing plates on both sides close towards the GIS component. If the connecting plate on one side contacts the GIS component first, the resistance will cause the connecting plate to react on the slider. The slider slides in the groove and compresses the first elastic element to achieve buffering, while the connecting plates on the other sides continue to close, achieving adaptive clamping. As the slider slides within the groove, it drives the telescopic swing arm to swing via the connecting rod, coordinating with the connecting plate to clamp the GIS component from different angles, forming a multi-point envelope. S3: As the lifting platform continues to move upward, all swing plates and telescopic swing rods come into contact with the GIS components. Then the mounting plate continues to move upward and the bottom plate comes into contact with the force plate at the bottom of the swing plate. The force plate drives the elastic telescopic rod to find and insert into the positioning hole on the connecting plate under pressure, mechanically locking the current position of the swing plate to prevent shaking during subsequent lifting. S4: The final mounting plate abuts against the cross plate of the front fork, making the mounting plate and the front fork a whole. The lifting platform and the movable support assembly are continuously lifted under the action of the first hydraulic cylinder. After the device rises to the preset installation point, the scissor bracket can be driven to extend and retract longitudinally by the second hydraulic cylinder, or the rotating tube and the mounting plate can be driven to rotate as a whole by the drive motor to fine-tune the GIS component and achieve millimeter-level precise positioning. S5: After installation, the descent process proceeds in reverse, and each mechanism is unlocked and released in sequence under the action of gravity and the reset device.

[0015] Compared with the prior art, the present invention provides a modular clamping and hoisting device and hoisting method for adaptive GIS components, which has the following advantages: 1. In this invention, when the operator activates the first hydraulic cylinder of the lifting unit to raise the hoisting platform, due to the huge weight of the GIS component, the front fork of the supporting component will lag behind due to inertia, while the mounting plate fixed to the platform body will rise first, resulting in relative displacement between the two. This displacement is immediately converted into traction force on the two moving frames through the pulleys and ropes set on the mounting plate, driving them to slide towards each other along the fork plate. This integrates the two independent operation processes of hoisting and clamping into a continuous process of automatic clamping triggered by a single lifting action, greatly simplifying the operation steps, significantly improving work efficiency, and fundamentally eliminating the safety risks caused by manual binding errors.

[0016] 2. In this invention, when the moving frame slides and drives the bidirectional screw to rotate through gear and rack transmission, the two sleeves move away from each other. Each sleeve pushes the slider to slide in the groove of the swing plate through the push-pull rod. If the swing plate on one side contacts the GIS component first, the resistance will force the slider on that side to compress the first elastic element and slide in the groove, while the swing plate on the other side will continue to close until it fully contacts the component. This allows each clamping arm to independently adapt to the contour of the component, ensuring that the clamping force is evenly distributed. It achieves surface contact rather than point contact or line contact, effectively protecting the surface of the component and avoiding equipment damage caused by uneven clamping force.

[0017] 3. In this invention, after all the swing plates have completed adaptive clamping, the bottom plate on the mounting plate will abut against the force plate on the swing plate. Under the push of the second elastic element, the elastic telescopic rod on the force plate will be pushed into the positioning hole on the connecting plate under pressure, forming a mechanical pin lock. This changes the clamping mechanism from a floating state to a rigid integrated state, completely eliminating the component shaking or clamping arm loosening that may be caused by equipment vibration or inertia during lifting and transportation, providing a crucial safety guarantee for high-altitude operations.

[0018] 4. In this invention, after the component is safely clamped and lifted, the operator can first drive the rotating tube and mounting plate to rotate as a whole via the drive motor to adjust the angle in the horizontal direction. Secondly, the scissor bracket can be extended and retracted via the second hydraulic cylinder to realize the longitudinal movement of the component. These functions enable the operator to make millimeter-level fine adjustments to the component at high altitude to ensure precise alignment with the docking foundation. This multi-degree-of-freedom precision control capability greatly overcomes the limitations of complex indoor environments, significantly improves installation accuracy and quality, reduces the time spent on repeated adjustments, and enhances overall work efficiency.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0023] like Figures 1 to 5 As shown, this embodiment proposes a modular clamping and hoisting device for adaptive GIS components, including a wheeled chassis 1, a counterweight 2, a lifting unit 4, and a modular clamping component 6. The counterweight 2 is fixed on the wheeled chassis 1, and a control console 3 is provided on the top of the counterweight 2. The lifting unit 4 is located on the front side of the counterweight 2 and is used to realize the vertical lifting of the hoisting platform 5. The hoisting platform 5 is connected to the output end of the lifting unit 4. The modular clamping component 6 is located on the hoisting platform 5 and is used to adaptively clamp the GIS components. The hoisting platform 5 includes a front fork 508 extending in the working direction, and the modular clamping component 6 is located on the front fork 508. When the lifting unit 4 drives the hoisting platform 5 to rise, it can drive the modular clamping component 6 to perform an adaptive clamping action on the GIS components placed on the front fork 508 through a mechanical linkage mechanism. Specifically, the operator moves the device to the work position using the wheeled chassis 1, and manipulates the device to allow the front fork 508 of the lifting platform 5, which extends in the work direction, to enter under the GIS component. The front fork 508 should adopt a narrow fork plate design, which can quickly extend under the GIS component in confined spaces, improving work efficiency and supporting the component. The operator starts the lifting unit 4 through the control console 3 to begin work. The lifting unit 4 drives the lifting platform 5 to rise vertically. During this rising process, the mechanical linkage mechanism is triggered. This mechanism uses the platform's rise as a single power source to automatically transmit mechanical motion to the front fork 508. Modular clamping component 6 drives the component to perform clamping actions. Modular clamping component 6 can adapt to the shape of GIS components to complete stable and reliable clamping. After the component is reliably clamped, the device can adjust the height through the lifting part 4 to finally complete the installation of the component. The lifting and clamping functions are linked by a mechanical linkage mechanism. The operator only needs to perform one action to start the lifting to automatically trigger and complete the clamping function, which reduces the number of power sources, reduces the equipment failure rate, and ensures the synchronous coordination of lifting and clamping actions. This greatly simplifies the operation process, reduces the dependence on operator skills, and thus significantly improves the overall operation efficiency.

[0024] like Figure 1 and Figure 3As shown, in a preferred embodiment, based on the above method, the lifting unit 4 further includes a bottom support 401 fixed to the outside of the counterweight 2, a movable support assembly 402 set on the bottom support 401, and a first hydraulic cylinder 403 fixed on the bottom support 401. The movable support assembly 402 includes at least two movable supports, and two adjacent movable supports are slidably connected, such as by a slide rail sliding block mechanism, so that they can extend and retract relative to each other. The sliding connection between the multi-stage movable supports provides good bending and torsional stiffness, so that the entire lifting unit 4 has small deformation and smooth movement when subjected to heavy loads, effectively preventing the platform and load from shaking during the lifting process, and providing a solid guarantee for high-altitude precision operation. The movable bracket at the bottom of the movable bracket assembly 402 is slidably connected to the bottom bracket 401, and the movable bracket at the top of the movable bracket assembly 402 is fixedly connected to the piston rod of the first hydraulic cylinder 403. Specifically, when the lifting platform 5 needs to be lifted, the hydraulic system supplies oil to the rodless chamber of the first hydraulic cylinder 403, pushing the piston rod outward. The thrust of the piston rod directly acts on the uppermost movable bracket of the movable bracket assembly 402, driving it to move upward. Since the adjacent movable brackets are slidably connected, the movement of the uppermost movable bracket will sequentially drive the movable brackets below it to extend step by step, ultimately achieving the overall extension of the movable bracket assembly 402, thereby lifting the lifting platform 5 fixed at its top to the required height. When it needs to be lowered, the hydraulic system supplies oil to the rod chamber of the first hydraulic cylinder 403, the piston rod retracts, and the uppermost movable bracket pulls the entire movable bracket assembly 402 to retract step by step, achieving a smooth descent of the platform.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the lifting platform 5 further includes a fixed frame 501 fixed on the uppermost movable bracket of the movable bracket assembly 402, a scissor-type bracket 502 rotatably connected to the fixed frame 501 at one end via a pin, a second hydraulic cylinder 503 disposed on the fixed frame 501 and used to drive the scissor-type bracket 502 to extend or retract, a mounting base 504 rotatably connected to the end of the scissor-type bracket 502 away from the fixed frame 501, and a fixed mounting base. The drive motor 505 is placed on the mounting base 504, the rotating tube 506 is rotatably connected to the mounting base 504 and connected to the output shaft of the drive motor 505, and the mounting plate 507 is fixedly connected to the rotating tube 506. The front fork 508 is connected to the mounting plate 507. The front fork 508 includes a cross plate 5081 connected to the mounting plate 507 and two fork plates 5082 fixedly set on the cross plate 5081. The spacing of the fork plates 5082 can be adapted to the bottom size of different specifications of GIS components, and has strong versatility. Specifically, when the front and rear positions of the GIS component need to be adjusted, the second hydraulic cylinder 503 is activated, causing the cylinder to extend and retract, thus deforming the scissor-type bracket 502. This, in turn, pushes the mounting base 504 and all its components to move forward or backward in a linear motion relative to the fixed frame 501. When the horizontal angle of the GIS component needs to be adjusted, the drive motor 505 is activated. The motor drives the rotating tube 506 to rotate via its output shaft, thereby causing the mounting plate 507 fixed thereto, the entire front fork 508, and the GIS component on it to rotate together in the horizontal plane. The operator can finely adjust the front and rear positions and horizontal angle of the GIS component while it is suspended, ensuring precise alignment with the docking foundation. Precise installation can be completed in a single lift, significantly improving installation quality and work efficiency. This solves the problem of relying solely on a mobile chassis for high-altitude positioning, which often requires repeated operations, resulting in low efficiency and difficulty in ensuring accuracy.

[0026] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the modular clamping component 6 further includes two symmetrically arranged movable frames 601, and the two movable frames 601 are slidably connected to the two fork plates 5082 of the front fork component 508 respectively. The mechanical linkage mechanism includes a pulley 5071 mounted on the mounting plate 507 and a pull rope 11 that passes around the pulley 5071. The two ends of the pull rope 11 are respectively connected to two movable frames 601. The pull rope 11 is made of high-strength synthetic fiber cable. When the hoisting platform 5 rises, the mounting plate 507 is relatively displaced relative to the fork 508 supporting the GIS components. The two moving frames 601 are pulled along the fork plate 5082 to slide towards each other by the pull rope 11. A limit frame for the sliding of the moving frames 601 should be provided on the fork plate 5082. Furthermore, the modular clamping component 6 also includes a fixed base 602 fixedly mounted on each movable frame 601, a bidirectional screw 603 rotatably connected to the fixed base 602, sleeves 604 threadedly connected to both ends of the bidirectional screw 603, and an adaptive clamping assembly provided for each sleeve 604. Furthermore, a movable gear 6031 is fixedly provided at the end of the bidirectional screw 603, a rack plate 10 that meshes with the movable gear 6031 is fixedly provided on the fork plate 5082, and an elastic telescopic rod 5083 is provided between the movable frame 601 and the fork plate 5082. When the movable frame 601 slides along the fork plate 5082, the bidirectional screw 603 is driven to rotate through the meshing transmission between the rack plate 10 and the movable gear 6031. Specifically, when the lifting unit 4 drives the hoisting platform 5 to rise, due to the enormous weight of the GIS components, the front fork 508 supporting the components will experience a brief relative lag due to inertia. Meanwhile, the mounting plate 507, connected to it via the horizontal plate 5081, will rise first along with the platform body. This relative displacement causes the pulley 5071 on the mounting plate 507 to rise, thereby pulling the rope 11 that passes around it. The two ends of the rope 11 then pull the two moving frames 601 (reducing the use of hydraulic components, lowering costs, and avoiding risks of leakage, pressure instability, and other malfunctions, thus extending equipment lifespan), causing them to slide towards the fork plate 5082. This converts the vertical upward motion of the platform into the horizontal closing motion of the clamping components. When moving, the bidirectional screw 603 moves. The movable gear 6031 at the end of the bidirectional screw 603 meshes with the rack plate 10 on the side of the fork plate 5082. The bidirectional screw 603 rotates in the fixed seat 602. The two ends of the bidirectional screw 603 are connected to two sleeves 604 with opposite thread directions. Each sleeve 604 corresponds to a set of adaptive clamping components to achieve adaptive clamping of the GIS component. This solution is designed for the special working condition of hoisting heavy GIS components in the confined space of a substation. It integrates the two independent high-risk and high-skill-requirement operations of lifting and adaptive clamping into a single automated and safe continuous operation triggered by a single lifting action, effectively improving the safety and efficiency of the operation.

[0027] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the adaptive clamping assembly further includes: a connecting plate 7 fixedly connected to the fixed base 602, a swing plate 701 rotatably connected to the connecting plate 7 via a pin, a groove 702 formed on the swing plate 701, a slider 703 slidably disposed in the groove 702, a first elastic element 704 disposed between the slider 703 and the inner wall of the groove 702, and a push-pull rod 705 with its two ends hinged to the sleeve 604 and the slider 703 respectively; When the bidirectional screw 603 rotates and drives the two sleeves 604 to move away from or closer to each other, the push-pull rod 705 pushes the slider 703, which in turn drives the swing plate 701 to rotate around its pin, thereby realizing the clamping or releasing action. Furthermore, the swing plate 701 is also provided with a locking mechanism, which includes: two recessed holes 8 opened on the swing plate 701, a sliding rod 801 slidably disposed in the recessed hole 8, a second elastic element 802 disposed between each sliding rod 801 and the inner wall of the corresponding recessed hole 8, a force plate 803 connected to the ends of the two sliding rods 801, a plurality of elastic telescopic inserts 804 disposed on the force plate 803, and a plurality of positioning inserts 805 opened on the connecting plate 7 and cooperating with the elastic telescopic inserts 804. A base plate 5072 that moves against the force plate 803 is fixedly disposed on the mounting plate 507. Specifically, when the bidirectional screw 603 rotates and drives the two sleeves 604 to move relative to each other, the sleeves 604 apply a pushing force to the slider 703 through the push-pull rod 705. The pushing force acts directly on the side wall of the slide groove 702 through the slider 703, driving the entire swing plate 701 to rotate around the pin axis towards the GIS component, thereby achieving the closing of the clamping arms. If one side of the swing plate 701 contacts the GIS component first, the resistance will prevent it from continuing to rotate. At this time, the continued movement of the sleeve 604 will force the slider 703 to slide within the slide groove 702 and compress the first elastic element 704. This process absorbs excessive stroke, avoiding hard collisions and damage to the GIS component. The excessively heavy GIS component is pushed forcefully, causing damage to the GIS component or the clamping parts. This achieves a transformation from rigid collision to compliant fit, effectively protecting the precision equipment. Meanwhile, the other clamping arms can continue to close during this period until all clamping arms are in contact with the component, achieving self-adaptation. Envelope clamping: After all the swing plates 701 have completed adaptive clamping, the lifting platform 5 continues to rise. At this time, the base plate 5072 on the mounting plate 507 will contact and abut against the force plate 803. The base plate 5072 applies pressure to the force plate 803. The pressure is transmitted through the slide rod 801, overcoming the force of the second elastic element 802, and pushing the force plate 803 to move towards the connecting plate 7. This forces at least one elastic telescopic rod 804 to be inserted into the positioning hole 805. The cooperation between the rod and the hole forms a mechanical pin lock, which completely fixes the swing angle of the swing plate 701, preventing it from shaking during subsequent lifting and transportation. This achieves rigid locking and eliminates the risk of decreased clamping force or loosening due to vibration, inertia, or mechanism failure, providing a crucial safety guarantee for high-altitude operations. It should be noted that the elastic element is usually a standard industrial part, and its fatigue life is predictable. Regular inspection and replacement are required, and maintenance costs are controllable.

[0028] like Figure 8 and Figure 9As shown, in a preferred embodiment, based on the above method, the swing plate 701 is further provided with an auxiliary clamping member for assisting in clamping the GIS component. The auxiliary clamping member includes a telescopic swing rod 9 that is rotatably connected to the end of the swing plate 701 away from the connecting plate 7 via a pin, and a connecting rod 901 that is hinged between the end of the telescopic swing rod 9 and the sleeve 604. Specifically, when the bidirectional screw 603 rotates and drives the sleeve 604 to move, the movement of the sleeve 604 is transmitted to the telescopic swing rod 9 through the connecting rod 901. The force applied by the connecting rod 901 to the end of the telescopic swing rod 9 forces the telescopic swing rod 9 to rotate around the pin that connects it to the swing plate 701. This rotation causes the telescopic swing rod 9 to move closer to the GIS component from another angle, eventually contacting the surface of the GIS component and applying an auxiliary clamping force. This solves the problem that for GIS components with a high center of gravity or irregular shape, clamping from only both sides may result in too few clamping force application points, and the component may still shake, rotate, or even tip over during transportation. By restricting the degrees of freedom of the GIS component in multiple directions, the component is more firmly positioned in the clamping space, thereby greatly improving the stability and safety during transportation.

[0029] This invention also discloses a method for hoisting an adaptive GIS component, which involves using the aforementioned modular clamping and hoisting device for the adaptive GIS component to perform the hoisting operation, including the following steps: S1: The operator moves the driving device so that the two fork plates 5082 of the front fork 508 of the lifting platform 5 extend under the GIS component to be lifted and support the GIS component. S2: Start the first hydraulic cylinder 403 of the lifting unit 4 to push the movable support assembly 402 to extend, thereby driving the entire lifting platform 5 to rise; Due to the enormous weight of the GIS components, initially, the fork 508 lags behind due to the load, while the mounting plate 507 rises first along with the main body of the lifting platform 5, resulting in relative displacement between the two. This relative displacement causes the pulley 5071 on the mounting plate 507 to rise, pulling the rope 11 that passes around it. The two ends of the rope 11 pull the two movable frames 601 to slide towards each other along the fork plate 5082. When the movable frame 601 slides, the movable gear 6031 fixed on it rolls along the rack plate 10 fixed on the fork plate 5082, converting the linear motion into the rotational motion of the bidirectional screw 603. The bidirectional screw 603 rotates and drives the sleeves 604 at both ends of it to move away from each other. The movement of each sleeve 604 pushes the slider 703 through the push-pull rod 705: In the initial stage, the force directly pushes the swing plate 701 to rotate around its hinge point with the connecting plate 7 through the slider 703, so that the swing plates 701 on both sides close towards the GIS component. If the connecting plate 7 on one side contacts the GIS component first, the resistance will cause the connecting plate 7 to react on the slider 703. The slider 703 slides in the groove 702 and compresses the first elastic element 704 to achieve buffering, while the connecting plates 7 on the other sides continue to close, achieving adaptive clamping. While sliding within the groove 702, the slider 703 drives the telescopic swing arm 9 to swing via the connecting rod 901, coordinating with the connecting plate 7 to clamp the GIS component from different angles, forming a multi-point envelope. S3: As the lifting platform 5 continues to move upward, all swing plates 701 and telescopic swing rods 9 come into contact with the GIS components. Then, the mounting plate 507 continues to move upward and the bottom plate 5072 comes into contact with the force plate 803 at the bottom of the swing plate 701. The force plate 803 drives the elastic telescopic rod 804 to find and insert into the positioning hole 805 on the connecting plate 7 under pressure, mechanically locking the current position of the swing plate 701 to prevent shaking during subsequent lifting. S4: The final mounting plate 507 abuts against the cross plate 5081 of the front fork 508, making the mounting plate 507 and the front fork 508 form a whole. The lifting platform 5 and the movable support assembly 402 are continuously lifted under the action of the first hydraulic cylinder 403. After the device rises to the preset installation point, the scissor bracket 502 can be driven to extend and retract longitudinally by the second hydraulic cylinder 503, or the rotating tube 506 and the mounting plate 507 can be driven to rotate as a whole by the drive motor 505 to fine-tune the GIS component and achieve millimeter-level precise positioning. S5: After installation, the descent process proceeds in reverse, and each mechanism is unlocked and released in sequence under the action of gravity and the reset device.

This relative displacement causes the pulley (5071) on the mounting plate (507) to lift, pulling the rope (11) that passes around it. The two ends of the rope (11) pull the two moving frames (601) to slide towards each other along the fork plate (5082).
