Description

Unitized and efficient installation and dismantling structure and method for large-size non-uniform thickness glazed tile curtain walls Technical Field

[0001] This invention belongs to the field of glass curtain wall installation technology, specifically, it relates to a unitized and efficient installation and dismantling structure and method for large-size non-uniform thickness glass curtain walls. Background Technology

[0002] With the increasing demand for personalization and functionality in the building decoration industry, large-size non-uniform thickness glazed tile curtain walls are becoming increasingly widely used in modern architecture due to their combination of aesthetic value and structural characteristics. The core feature of this type of curtain wall is the significant thickness difference of the glazed tile components. Some areas (thick areas) are thicker and heavier to bear higher loads or meet structural strength requirements; while other areas (thin areas) are thinner and less resistant to compression damage to fit the shape or reduce weight. This characteristic of "high self-weight in thick areas and weak resistance to damage in thin areas" places stringent requirements on the adsorption and fixation during the installation and dismantling of the curtain wall.

[0003] Currently, the industry commonly uses traditional suction cup adsorption structures for the installation and dismantling of large-size glazed curtain walls. These suction cups employ uniform adsorption pressure. When adsorbing a large glazed curtain wall, to meet the load-bearing requirements of the thicker sections with their high self-weight, traditional structures require a high adsorption pressure to ensure stable adsorption and prevent displacement or detachment during hoisting. However, when this uniform high-pressure adsorption mode is applied to thinner sections, excessive adsorption pressure can continuously compress the thinner glazed sections, easily leading to cracks and damage, severely affecting the integrity of the curtain wall components and construction quality. If the adsorption pressure is reduced to protect the thinner sections, the thicker sections, due to insufficient adsorption force, cannot support their own high self-weight, easily leading to adsorption failure and component slippage during hoisting and movement, posing a safety hazard that not only affects construction efficiency but may also cause personal injury and property damage.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a unitized and efficient installation and dismantling structure for large-size non-uniform thickness glazed curtain walls, including a pair of parallel connected covers.

[0006] A synchronization frame is installed between the connecting covers, and a pair of positioning covers are installed on the synchronization frame. Insert covers are inserted into the pair of positioning covers, and suction cups are installed at the ends of the insert covers. The suction cups adhere to the non-uniform thickness glass, and the insert covers slide outwards from the positioning covers, allowing the corresponding suction cups to adhere to the thin areas of the non-uniform thickness glass. Each suction cup, insert cover, and positioning cover is interconnected with a negative pressure chamber inside the connecting cover, and a second piston slides between the corresponding negative pressure chambers. When the insert cover slides within the positioning cover, the volume of the negative pressure chamber communicating with the thin areas of the non-uniform thickness glass is larger than the volume at the other end. A driving assembly and a locking assembly are installed on the connecting cover. The driving assembly drives the pair of second pistons to slide synchronously, and the locking assembly locks the driving assembly during hoisting. When the second pistons slide, the two negative pressure chambers increase in volume by the same amount. At this time, the pressure in the negative pressure chamber communicating with the thin areas of the non-uniform thickness glass is less than the pressure at the other end, allowing for different pressure adsorption and positioning at different thickness locations.

[0007] In a preferred embodiment of the present invention, mounting plates are installed at both ends of the synchronization frame, the synchronization frame and the mounting plates are in the shape of an I-beam, the mounting plates are connected to the side wall of the connecting cover by bolts, and a reinforcing rib is installed between the mounting plate and the synchronization frame, the reinforcing rib being triangular in shape.

[0008] In a preferred embodiment of the present invention, a first piston is installed at the end of the insert cover. The first piston is slidably disposed on the inner side wall of the positioning cover. A connecting frame is installed on the outer side wall of the insert cover. A positioning rod is movably installed through the connecting frame. Positioning seats are installed at both ends of the positioning rod. The positioning seats are installed on the side wall of the positioning cover. A positioning spring is sleeved on the side wall of the positioning rod. One end of the positioning spring is engaged with the positioning seat, and the other end of the positioning spring is engaged with the connecting frame.

[0009] In a preferred embodiment of the present invention, a first lead screw is rotatably installed inside the connecting cover. A fixed seat is rotatably installed at one end of the first lead screw, and the fixed seat is connected to the inlet of the insert cover. A knob is installed at the other end of the first lead screw. A sliding sleeve is engaged on the first lead screw, and a connecting plate is installed on the sliding sleeve. The end of the connecting plate is connected to the surface of the insert cover.

[0010] In a preferred embodiment of the present invention, a positioning plate is installed on the side wall of the second piston, and a synchronization plate is installed between the positioning plates located on the same side between adjacent second pistons. A limiting seat is installed inside the communicating cover, and the limiting seat is used to divide the chamber. The synchronization plate passes through the limiting seat. A rod is installed at the other end of the second piston, and the rod passes through the communicating cover. The end of the rod is connected to the drive assembly.

[0011] In a preferred embodiment of the present invention, the driving assembly includes a pair of sliders that slide against each other, each slider having a rocker arm rotatably mounted on it. The rocker arm is in an inclined state, and a top plate is rotatably mounted at the end of the rocker arm. Both ends of the top plate are connected to the insert rod.

[0012] In a preferred embodiment of the present invention, a second lead screw is rotatably mounted between the connecting covers. A handle is installed at the end of the second lead screw. A pair of screw threads with opposite directions are formed on the second lead screw, and the screw threads are engaged with the corresponding slider. A limit rod is movably provided through the inner sidewall of the slider. The two ends of the limit rod are on the sidewall of the connecting cover. The locking assembly is used to lock the position of the slider.

[0013] In a preferred embodiment of the present invention, the locking assembly includes a lifting seat, which is installed on the side wall of the connecting cover. The lifting seat has an inner cavity, and a friction plate is inserted into the lifting seat. The friction plate moves upward and presses against the friction groove at the bottom of the slider to position the slider. The bottom of the friction plate communicates with the inner cavity. A protrusion is installed on the friction plate and is located on the outside of the lifting seat.

[0014] In a preferred embodiment of the present invention, a top block is inserted into the lifting seat, the top of the top block is in communication with the inner cavity, a first locking block is installed on the top of the top block and the first locking block is located in the inner cavity, a second locking block is installed on the top block located outside the inner cavity, a hanger is installed at the bottom of the top block, and a lifting ring is installed on the hanger. During the lifting process of the lifting ring, the top block slides inside the inner cavity, compresses the volume of the inner cavity, and pushes the friction plate to move upward through the change of air pressure.

[0015] The method for efficient installation and dismantling of large-size non-uniform thickness glazed curtain walls in a modular fashion includes the following steps: Step 1: Initial positioning and thick area adsorption. Clearly define the distribution of thick and thin areas in the non-uniform thickness glazed curtain wall. Ensure that the positioning cover, insert cover, and suction cup on the connecting cover directly adhere to the surface of the thick area. Fix the mounting plates at both ends of the synchronous frame to the sidewalls of the connecting cover using bolts. Utilize triangular reinforcing ribs to enhance structural rigidity. Step 2: Thin area suction cup position adjustment. Rotate the knob on the connecting cover corresponding to the thin area, causing the first lead screw to rotate. This moves the engaging sliding sleeve along the lead screw axis, pulling the insert cover within the positioning cover via the connecting plate. The connecting frame slides along the positioning rod, the positioning spring extends and retracts for buffering, and the first piston slides along the inner wall of the positioning cover for sealing until the suction cup precisely adheres to the thin area. Step 3: Negative pressure chamber pressure adjustment. Rotate the handle at the end of the second lead screw... Step 1: Move and lock the sliders on both sides along the limiting rod. Tilt the rocker arm to push the top plate and the insert rod, causing the second piston to slide synchronously in the negative pressure chamber. This makes the volume of the negative pressure chamber on the thin side larger than that on the thick side, forming a differential adsorption where the pressure in the thin side is lower than that in the thick side. Step 2: Lifting, moving and locking. Connect the lifting equipment through the lifting ring and lift. The lifting frame moves the top block up along the lifting seat. The first locking block compresses the inner cavity, increasing the air pressure. This pushes the friction plate up and locks it with the friction groove of the slider, maintaining a stable pressure in the negative pressure chamber. Smoothly move the non-uniform thickness glass to the installation position. Step 3: Disassembly and separation. Lower the lifting ring to move the top block down. The air pressure in the inner cavity decreases, the friction plate resets and releases the lock. Turn the handle in the opposite direction to reset the second piston. The pressure in the negative pressure chamber is balanced. Then turn the knob in the opposite direction to retract the insert cover, causing the suction cup to separate from the thin and thick areas in sequence, completing the disassembly.

[0016] Compared with existing technologies, this invention has the following advantages: It achieves targeted adaptation through precise negative pressure chamber pressure adjustment. For thick areas with high self-weight, the structure utilizes a drive component to slide the second piston, making the final volume of the negative pressure chamber on the thick area side smaller. Based on the principle that under isothermal conditions, the smaller the negative pressure chamber volume, the more significant the pressure drop, resulting in a higher negative pressure on the thick area side. This provides a stable and strong adsorption force, effectively supporting the high self-weight of the thick area and avoiding the risk of hoisting deviation or detachment due to insufficient adsorption force. For thin areas with weak damage resistance, the adjustment makes the final volume of the negative pressure chamber on the thin area side larger. At this point, the pressure drop on the thin area side is more gradual, and the negative pressure is lower, precisely forming a weak adsorption effect. This satisfies the basic adsorption requirements of the thin area while avoiding excessive suction force causing squeezing damage to the thin area glass, protecting the structural integrity of the thin area. Ultimately, it achieves the safety and efficiency of the installation and dismantling process of large-size non-uniform thickness glazed curtain walls while ensuring the stable load-bearing capacity and damage resistance protection of the thick area.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0021] Example 1: As shown in Figures 1 to 9, the unitized and efficient installation and dismantling structure of a large-size non-uniform thickness glazed curtain wall includes a pair of parallel connecting covers 1.

[0022] A synchronization frame 11 is installed between the connecting covers 1. A pair of positioning covers 12 are installed on the synchronization frame 11. An insert cover 121 is inserted into the pair of positioning covers 12. A suction cup 122 is installed at the end of the insert cover 121. The suction cup 122 is attached to the non-uniform thickness glass 4, and the insert cover 121 slides outward from the positioning cover 12 to allow the corresponding suction cup 122 to be attached to the thin area of ​​the non-uniform thickness glass 4. The interior of each suction cup 122, insert cover 121, and positioning cover 12 is connected to a negative pressure cavity 22 opened inside the connecting cover 1, and a first slidably arranged between the corresponding negative pressure cavities 22. Two pistons 21, when the insert cover 121 slides in the positioning cover 12, the volume of the negative pressure cavity 22 that is connected to the thin area of ​​the non-uniform thickness glass 4 is larger than the volume of the other end; the connecting cover 1 is equipped with a driving component and a locking component. The driving component is used to drive a pair of second pistons 21 to slide synchronously, and the locking component is used to lock the driving component during hoisting; when the second pistons 21 slide, the two negative pressure cavities 22 increase in volume by the same amount. At this time, the pressure of the negative pressure cavity 22 that is connected to the thin area of ​​the non-uniform thickness glass 4 is less than the pressure of the other end, and different pressure adsorption positioning is adopted to adapt to different thickness positions.

[0023] As shown in Figures 1 to 9, in this specific embodiment, mounting plates 111 are installed at both ends of the synchronous frame 11. The synchronous frame 11 and the mounting plates 111 are I-shaped. The mounting plates 111 are connected to the side wall of the connecting cover 1 by bolts. A reinforcing rib 112 is installed between the mounting plates 111 and the synchronous frame 11. The reinforcing rib 112 is triangular. The I-shaped synchronous frame 11 and the mounting plates 111, together with the triangular reinforcing rib 112, significantly enhance the overall structural rigidity, preventing deformation of the connecting cover 1 due to load concentration during thick-area adsorption, ensuring the stability of thick-area adsorption and the service life of the structure. At the same time, the bolt connection facilitates later maintenance and disassembly.

[0024] As shown in Figures 1 to 9, a first piston 127 is further installed at the end of the insert cover 121. The first piston 127 is slidably disposed on the inner side wall of the positioning cover 12. A connecting frame 123 is installed on the outer side wall of the insert cover 121. A positioning rod 124 is movably mounted through the connecting frame 123. Positioning seats 125 are installed at both ends of the positioning rod 124. The positioning seats 125 are installed on the side wall of the positioning cover 12. A positioning spring 126 is sleeved on the side wall of the positioning rod 124. One end of the positioning spring 126 is engaged with the positioning seat 125, and the other end of the positioning spring 126 is engaged with the connecting frame 123. The first piston 127 achieves a sealed fit between the positioning cover 12 and the insert cover 121, preventing air leakage from the negative pressure chamber 22 from affecting the pressure regulation effect. At the same time, the positioning rod 124 and the positioning spring 126 cooperate to provide stable guidance for the sliding of the insert cover 121, and can also buffer the impact force through the spring extension and contraction, avoiding damage caused by the suction cup 122 hitting the thin area of ​​the non-uniform thickness glass 4, thus improving the safety of the adjustment process.

[0025] As shown in Figures 1 to 9, a first lead screw 13 is rotatably mounted inside the connecting cover 1. A fixed seat 134 is rotatably mounted at one end of the first lead screw 13, and the fixed seat 134 is connected to the inlet of the insert cover 121. A knob 131 is mounted at the other end of the first lead screw 13. A sliding sleeve 132 is engaged on the first lead screw 13, and a connecting plate 133 is mounted on the sliding sleeve 132. The end of the connecting plate 133 is connected to the surface of the insert cover 121. Through the adjustment structure composed of the knob 131, the first lead screw 13, the sliding sleeve 132, and the connecting plate 133, precise linear sliding of the insert cover 121 can be achieved. The operator only needs to rotate the knob 131 to control the suction cup 122 to align with the thin area of ​​the non-uniform thickness glass 4, without complicated operations, which greatly improves the convenience and accuracy of thin area adsorption and positioning, and adapts to the adjustment needs of local size differences in thin areas.

[0026] Example 2: The difference between this example and the previous one is as follows: As shown in Figures 1 to 9, a positioning plate 211 is installed on the side wall of the second piston 21. A synchronization plate 212 is installed between the positioning plates 211 located on the same side between adjacent second pistons 21. A limiting seat 213 is installed inside the connecting cover 1 to divide the chamber. The limiting seat 213 is movably connected to the synchronization plate 212 and the limiting seat 213. A rod 2 is installed at the other end of the second piston 21, movably connecting to the connecting cover 1, and the end of the rod 2 is connected to the drive assembly. Through the cooperation of the positioning plate 211 and the synchronization plate 212, the second pistons 21 on both sides slide synchronously, avoiding pressure imbalance in the negative pressure chamber 22 due to asynchronous piston movement. Simultaneously, the limiting seat 213 precisely divides the chamber, ensuring independent operation of the thick and thin negative pressure chambers 22, providing structural support for differentiated pressure regulation and improving the stability and reliability of pressure regulation.

[0027] As shown in Figures 1 to 9, in a specific embodiment, the driving assembly includes a pair of sliders 232 that slide against each other. Each slider 232 has a rocker arm 231 rotatably mounted on it. The rocker arm 231 is in an inclined state, and a top plate 23 is rotatably mounted at the end of the rocker arm 231. Both ends of the top plate 23 are connected to the insertion rod 2. Through the driving structure formed by the sliders 232, the inclined rocker arm 231, and the top plate 23, the lateral sliding of the sliders 232 is converted into the longitudinal pushing of the top plate 23, thereby driving the insertion rod 2 and the second piston 21 to move. This structure has high transmission efficiency and uniform force distribution, avoiding jamming when the second piston 21 slides, ensuring smooth volume adjustment of the negative pressure chamber 22, and providing power for precise pressure control.

[0028] As shown in Figures 1 to 9, a second lead screw 24 is rotatably mounted between the connecting covers 1. A handle 241 is installed at the end of the second lead screw 24. The second lead screw 24 has a pair of threads with opposite directions of rotation, and the threads mesh with the corresponding sliders 232. A limit rod 233 is movably installed through the inner wall of the slider 232. The two ends of the limit rod 233 are on the side wall of the connecting cover 1, and the locking assembly is used to lock the position of the slider 232. By cooperating with the limit rod 233, the second lead screw 24 with the reverse threads can drive the sliders 232 on both sides to slide synchronously in opposite directions by rotating the handle 241. There is no need to adjust the position of the sliders 232 separately, simplifying the operation steps. At the same time, the limit rod 233 prevents the sliders 232 from deviating during sliding, ensuring the precise transmission of the drive assembly and further improving the convenience and accuracy of pressure adjustment in the negative pressure chamber 22.

[0029] As shown in Figures 1 to 9, in a specific embodiment, the locking assembly includes a lifting seat 3, which is installed on the side wall of the connecting cover 1. The lifting seat 3 has an inner cavity 31, and a friction plate 311 is inserted into it. The friction plate 311 moves upward and presses against the friction groove at the bottom of the slider 232 to position the slider 232. The bottom of the friction plate 311 is connected to the inner cavity 31. A protrusion 312 is installed on the friction plate 311, positioned outside the lifting seat 3. Through the locking structure formed by the lifting seat 3, the inner cavity 31, and the friction plate 311, the slider 232 is positioned by the pressing contact between the friction plate 311 and the friction groove of the slider 232, thereby locking the position of the second piston 21. This ensures a stable pressure difference in the negative pressure chamber 22, preventing changes in the suction force due to loosening of the drive assembly during hoisting. Simultaneously, the protrusion 312 facilitates manual adjustment of the friction plate 311, improving the flexibility of switching the locking state.

[0030] As shown in Figures 1 to 9, a top block 32 is further inserted into the lifting seat 3. The top of the top block 32 is connected to the inner cavity 31. A first locking block 321 is installed on the top of the top block 32, and the first locking block 321 is located in the inner cavity 31. A second locking block 322 is installed on the top block 32 located outside the inner cavity 31. A hanger 33 is installed at the bottom of the top block 32, and a lifting ring 331 is installed on the hanger 33. During the lifting process of the lifting ring 331, the top block 32 slides inside the inner cavity 31, compressing the volume of the inner cavity 31, and pushing the friction plate 311 upward through the change of air pressure. The linkage structure consisting of top block 32, first locking block 321, hanger 33 and lifting ring 331 enables automatic locking when the hoisting is under force: the lifting ring 331 is under force and drives the top block 32 to move upward, compressing the air pressure in the inner cavity 31 to push the friction plate 311 to lock the slider 232. No additional manual operation of the locking components is required, which improves the automation and safety of the hoisting process. At the same time, the second locking block 322 prevents the top block 32 from disengaging from the lifting seat 3, ensuring the reliable operation of the locking structure.

[0031] This invention also discloses a method for efficient unitized installation and dismantling of large-size non-uniform thickness glazed curtain walls, the steps of which are as follows: Step 1: Initial positioning and thick area adsorption, clarifying the distribution of thick and thin areas of the non-uniform thickness glazed 4, so that the positioning cover 12, insert cover 121 and suction cup 122 corresponding to the thick area on the connecting cover 1 directly adhere to the surface of the thick area, and fix the mounting plates 111 at both ends of the synchronous frame 11 to the side wall of the connecting cover 1 with bolts, and use triangular reinforcing ribs 112 to enhance the structural rigidity; Step 2: Thin area suction cup position adjustment, rotation The knob 131 on the connecting cover 1 corresponding to the thin area drives the first lead screw 13 to rotate, causing the engaging sliding sleeve 132 to move along the lead screw axis. This moves the insert cover 121 to slide inside the positioning cover 12 via the connecting plate 133. The connecting bracket 123 slides along the positioning rod 124, the positioning spring 126 extends and retracts for buffering, and the first piston 127 slides along the inner wall of the positioning cover 12 in a sealing manner until the suction cup 122 precisely fits the thin area. Step 3: Adjust the pressure of the negative pressure chamber by rotating the handle 241 at the end of the second lead screw 24. The two sliders 232 slide towards each other along the limiting rod 233. The tilting rocker arm 231 pushes the top plate 23 and the insertion rod 2, causing the second piston 21 to slide synchronously in the negative pressure chamber 22, making the volume of the negative pressure chamber 22 on the thin side larger than that on the thick side, forming a differential adsorption where the pressure in the thin area is lower than that in the thick area; Step 4: Lifting, moving and locking. The lifting equipment is connected through the lifting ring 331 and lifted. The lifting frame 33 drives the top block 32 to move upward along the lifting seat 3. The first locking block 321 compresses the inner cavity 31 to increase the air pressure, pushing the friction... The rubbing plate 311 moves upward and locks with the friction groove of the slider 232, keeping the pressure in the negative pressure chamber 22 stable, and smoothly moves the non-uniform thickness glass 4 to the installation position; Step 5: Disassembly and separation, lower the lifting ring 331 to move the top block 32 down, reduce the air pressure in the inner cavity 31, reset the rubbing plate 311 to release the lock, rotate the handle 241 in the opposite direction to reset the second piston 21, balance the pressure in the negative pressure chamber 22, and then rotate the knob 131 in the opposite direction to retract the insert cover 121, so that the suction cup 122 separates from the thin area and the thick area in sequence, completing the disassembly.

[0032] The implementation principle of the unitized and efficient installation and dismantling structure for large-size non-uniform thickness glazed curtain walls of the present invention is as follows: This structure targets the core characteristics of large-size non-uniform thickness glazed glass 4, namely "high self-weight load in thick areas and weak damage resistance in thin areas". It takes "fixed adsorption in thick areas + dynamic adjustment in thin areas" as the core logic. Through the coordinated operation of components such as the connecting cover 1, positioning cover 12, and negative pressure chamber 22, it achieves full-process adaptation from precise adsorption to stable movement and convenient installation and dismantling. The specific implementation process is as follows: First, initial positioning is performed. After clarifying the thickness distribution of the non-uniform thickness glazed glass 4, the fixed adsorption of the thick areas is completed first. The positioning cover 12 and the insert cover 121 corresponding to the thick areas on the connecting cover 1 are preset fixed structures and do not require additional adjustment. The suction cup 122 at the end of the insert cover 121 directly adheres to the surface of the thick area. Meanwhile, the mounting plates 111 at both ends of the synchronous frame 11 are tightly screwed to the side wall of the connecting cover 1 by bolts. The triangular reinforcing ribs 112 between the mounting plates 111 and the synchronous frame 11 can effectively disperse the concentrated load during thick area adsorption, avoid overall structural deformation, and provide a stable foundation for subsequent thin area adjustment.

[0033] For thin areas, due to local size differences, operators must first observe and determine the target position that the suction cup 122 needs to adhere to, and then activate the corresponding side adjustment component for precise alignment.

[0034] Next, the position adjustment of the thin area suction cup 122 is carried out. The operator rotates the knob 131 corresponding to the thin area on the connecting cover 1. The knob 131 drives the first lead screw 13 connected coaxially to rotate. Since the first lead screw 13 and the sliding sleeve 132 are meshed, the sliding sleeve 132 will move along the axial direction of the first lead screw 13, and then pull the insert cover 121 to slide inside the positioning cover 12 through the connecting plate 133. The sliding direction can be flexibly adjusted to extend outward according to the position requirements of the thin area. During this process, the connecting frame 123 fixed to the outer wall of the insert cover 121 will slide synchronously along the positioning rod 124. The two ends of the positioning rod 124 are fixed to the side wall of the positioning cover 12 through the positioning seat 125, forming a stable guide structure to prevent the insert cover 121 from shifting laterally when sliding. At the same time, the positioning spring 126 sleeved on the positioning rod 124 will extend and retract with the movement of the connecting frame 123. When the insert cover 121 extends outward, the positioning spring 126 is stretched to generate a buffer force to prevent the suction cup 122 from hitting the glass surface due to excessive adjustment speed. When the insert cover 121 retracts inward, the positioning spring 126 contracts to assist in reset, ensuring that the adjustment process is smooth and controllable. In addition, the first piston 127 installed at the end of the insert cover 121 will slide synchronously on the inner wall of the positioning cover 12. The first piston 127 and the inner wall of the positioning cover 12 maintain a sealed fit, which can not only prevent air leakage during subsequent negative pressure adsorption, but also further limit the sliding trajectory of the insert cover 121, ensuring that the suction cup 122 always moves in a direction perpendicular to the glass surface until it completely adheres to the thin area, achieving the effect of no offset and precise alignment of the thin area adsorption point.

[0035] After the suction cups 122 in the thick and thin areas are positioned, the pressure in the negative pressure chamber 22 is adjusted by the drive component to achieve differentiated suction force adaptation. The operator rotates the handle 241 at the end of the second lead screw 24. The second lead screw 24 has a pair of screw threads with opposite directions, which engage with the sliders 232 on both sides respectively. Therefore, when the handle 241 is rotated, the sliders 232 on both sides will slide towards each other along the limiting rod 233. When the slider 232 moves, the tilting rocker arm 231 connected to its top will push the top plate 23 to move horizontally. The two ends of the top plate 23 are fixedly connected to the insertion rod 2, which in turn drives the insertion rod 2 to pass through the side wall of the connecting cover 1 and push the second piston 21 to slide in the negative pressure chamber 22. At this time, the positioning plate 211 of the side wall of the adjacent second piston 21 is connected through the synchronization plate 212 to ensure that the second pistons 21 on both sides move synchronously. When the second piston 21 slides to the preset position, the volume of the negative pressure chamber 22 on the thin side is adjusted to be greater than the volume of the negative pressure chamber 22 on the thick side, and the amount of gas added to both chambers is the same.

[0036] According to the principle that "under isothermal conditions, the larger the volume of the negative pressure chamber, the more significant the pressure drop": the volume of the thick area side chamber is small, the pressure drop is small, and the final negative pressure is large, which can stably support the high self-weight of the thick area; the volume of the thin area side chamber is large, the pressure and negative pressure are small, avoiding excessive suction to damage the thin area glass. The volume difference is directly converted into a pressure difference, which accurately matches the adsorption requirements of non-uniform thickness glass 4.

[0037] When hoisting and moving non-uniform thickness glass 4, the locking component will automatically activate to ensure stable adsorption. The operator connects to the hoisting equipment through the lifting ring 331 on the hanger 33. When hoisting, the lifting ring 331 is pulled upward by the force, which in turn drives the top block 32 to slide upward along the lifting seat 3. The first locking block 321 at the top of the top block 32 is located in the inner cavity 31 of the lifting seat 3. As the top block 32 moves upward, the first locking block 321 compresses the volume of the inner cavity 31, and the air pressure in the inner cavity 31 increases, pushing the friction plate 311 placed in the inner cavity 31 to move upward until the top of the friction plate 311 is in close contact with the friction groove at the bottom of the slider 232. At this time, the slider 232 is locked by the friction plate 311 and cannot slide along the limit rod 233. Then, the position of the second piston 21 is fixed by the rocker arm 231, the top plate 23 and the insertion rod 2. The pressure difference of the negative pressure chamber 22 remains unchanged, and the suction force of the suction cup 122 on the thick and thin areas is stable. In this state, the non-uniform thickness glass 4 can be moved smoothly to the installation position. The supporting effect of the synchronous frame 11 and the reinforcing rib 112 can further disperse the weight of the glass and avoid structural deformation during the movement, which would cause the glass to shift.

[0038] The disassembly process is achieved through reverse operation for convenient separation: First, the hoisting equipment slowly lowers the lifting ring 331, the hanger 33 drives the top block 32 to slide downwards, the volume of the inner cavity 31 recovers, the air pressure decreases, the friction plate 311 resets under its own gravity, separates from the friction groove of the slider 232, and releases the locked state; then, the handle 241 of the second lead screw 24 is rotated in the opposite direction, the slider 232 slides in the opposite direction, and the second piston 21 is driven back to the initial position through the rocker arm 231 and the top plate 23, the pressure of the negative pressure chambers 22 on both sides tends to be balanced, and the suction force of the suction cup 122 weakens; then, the knob 131 corresponding to the thin area is rotated in the opposite direction, the first lead screw 13 drives the sliding sleeve 132 and the connecting plate 133 to reset, the insert cover 121 retracts along the positioning cover 12, and the suction cup 122 separates from the thin area; while the suction cup 122 of the thick area, being a fixed structure, is directly separated from the surface of the thick area along with the overall structure, and finally the disassembly of the non-uniform thickness glass 4 is completed.

[0039] The entire implementation process revolves around the core principle of "fixing the thick area and adjusting the thin area," which not only precisely adapts to the structural characteristics of non-uniform thickness glazed glass 4, but also simplifies the installation and dismantling steps through mechanized components. This ensures construction safety while improving efficiency, and is especially suitable for unitized construction scenarios of large-size non-uniform thickness glazed glass curtain walls.
