Description

Technical Field

[0001] The present invention relates to the technical field of glass curtain wall installation, in particular to a flatness-adjustable positioning auxiliary device for a special-shaped glass curtain wall and a method for using the same. Background Art

[0002] Shaped glass curtain walls are a specialized type of architectural curtain wall that utilizes non-standard glass shapes to create a unique appearance and visual effect. Due to its unique artistic value and visual impact, this curtain wall design is widely used in various types of buildings, including commercial buildings, residential projects, and public facilities. In modern architectural design, architects are increasingly employing three-dimensional free-form curved glass curtain walls in pursuit of novelty, uniqueness, and artistic effect. These designs not only enhance the aesthetic value of a building but also imbue it with a distinct personality and identity.

[0003] However, this complex, special-shaped glass curtain wall design also presents numerous construction challenges. Conventional installation methods for special-shaped glass curtain walls typically use straps to secure the glass, then hoist the straps and glass together using a crane. While this method allows for the lifting and installation of glass, it presents numerous practical challenges: (1) Glass shaking problem: During the hoisting process, glass tends to shake in the air, especially when it is close to the wall. There is a high risk of collision between the glass and the wall or other structural components. Such collision may not only cause damage to the glass, but also pose a safety hazard to the construction workers and the surrounding environment.

[0004] (2) Difficulty in ensuring flatness: The glass surface of a special-shaped glass curtain wall is usually a complex curved surface, and traditional installation methods make it difficult to accurately control the flatness of the glass. During the installation process, the flatness of the glass directly affects the overall appearance and sealing performance of the curtain wall. If the flatness does not meet the standard, it will not only affect the aesthetics of the building, but may also cause problems such as rainwater leakage.

[0005] (3) Low installation efficiency: Due to the complex shape of glass, the position and angle of the glass need to be frequently adjusted during the installation process, which not only increases the difficulty of construction but also prolongs the construction time. Traditional installation methods mainly rely on manual operation, with a low degree of automation, which is prone to insufficient installation accuracy due to human factors.

[0006] (4) Poor adaptability: Existing installation tools are difficult to adapt to glass of different specifications and shapes, which further increases the difficulty of adjusting the flatness. In the installation of complex special-shaped glass curtain walls, there is a lack of an installation auxiliary device that can flexibly adapt to glass of different sizes and shapes. Summary of the Invention

[0007] The technical problem to be solved by this invention is to address the shortcomings of existing technologies by providing an adjustable flatness positioning auxiliary device for special-shaped glass curtain walls and its use method.

The ends of the extension arms are connected to the curved glass by suction via vacuum suction cups. There are seven vacuum suction cups, four of which are movably arranged at the ends of the extension arms, and three are fixedly installed on the side of the shell at equal intervals.

[0009] A driving assembly is provided on the inner wall of the shell and at the hinged end of the extended arm.

[0012] Preferably, the locking assembly includes a ratchet ring, which is fixedly mounted on the outer wall of the sleeve at the end of the extended arm. A pawl is engaged on the side of the ratchet ring. The bottom of the pawl is movably mounted on the inner wall of the shell through a fixed hinge seat. A torsion spring is mounted on the hinge shaft of the fixed hinge seat.

[0014] Preferably, the electric telescopic rod, control integrated valve, air pump, reducer A, reducer B and electric push rod are all connected to the PLC controller signal.

[0015] The present invention also provides the following technical solutions: A method for using a flatness-adjustable positioning auxiliary device for a special-shaped glass curtain wall comprises the following steps: S1. Connect the device to the external crane through the connecting rod; S2. The crane controls the extension arm to approach the curved glass, so that the three vertical vacuum suction cups are attached to the surface of the curved glass. S3, reducer B drives the shaft and the cross-axis universal joint to rotate, so that the extension arms on both sides move closer to the curved glass until all four vacuum suction cups are attached to the curved glass; S4. The air pump starts to operate, and the vacuum cup is evacuated by controlling the integrated valve and the hose, so that the vacuum cup and the curved glass are tightly adsorbed under negative pressure. S5, reducer A drives the reciprocating screw to rotate, so that the screw sleeve, ball joint seat, ball joint head and vacuum suction cup move to adapt to the size of the curved glass; S6, the vacuum suction cup adapts to the curved surface of the glass through the ball joint seat and the ball joint head; S7. Adjust the tilt angle of the housing through the electric telescopic rod to make the curved glass fit the wall; S8. After the installation is completed, the air pump stops running, the control integrated valve opens, and the vacuum suction cup releases the curved glass; S9, the electric push rod pushes the crossbar outward, and the sliding rod pulls the pawl away from the ratchet ring to unlock the extension arm; S10: The extension arm returns to its original position and the device is removed to prepare for the next installation and use.

[0016] Preferably, the reducer A and reducer B are both programmable reducers, and their speed and direction can be precisely controlled by a PLC controller; the adsorption force of the vacuum suction cup can be adjusted by controlling the integrated valve to adapt to curved glass of different sizes and shapes.

[0017] Preferably, the telescopic length of the electric telescopic rod can be precisely controlled by a PLC controller to achieve multi-angle adjustment of the shell.

[0018] Preferably, the entire operation process of the special-shaped structure glass curtain wall flatness adjustable positioning auxiliary device can be automatically controlled by a PLC controller, reducing manual intervention.

[0019] The positive beneficial effects of the present invention are as follows: Compared with the prior art, the flatness-adjustable positioning auxiliary device for special-shaped structural glass curtain walls of the present invention and its use method have the following significant positive and beneficial effects: 1. Accurate flatness adjustment and adaptability: (1) Multi-point adsorption and dynamic adjustment: The present invention uses three vertical vacuum suction cups to initially adsorb the shell onto the curved glass surface. The four vacuum suction cups on the two side extension arms then further adsorb the glass, forming a multi-point fixation. Compared to traditional single-point adsorption or simple strap fixation, this multi-point adsorption method can more evenly distribute the force on the glass, avoiding deformation or damage to the glass caused by localized uneven force, and significantly improving the stability of the glass during the hoisting process.

[0020] (2) Size and surface adaptation: For glass of different sizes and complex curves, the present invention uses a reducer A to drive the reciprocating screw to rotate, driving the screw sleeve, ball joint seat, ball joint head and vacuum suction cup to move along a specific trajectory, so as to achieve flexible adjustment of the position of the vacuum suction cup to accurately adapt to the size and shape of the glass. At the same time, the vacuum suction cup can automatically fit the curved surface of the glass with the help of the universal adjustment function of the ball joint seat and ball joint head, ensuring uniform distribution of suction force and further ensuring the flatness of the glass. This innovative design effectively solves the problem of the difficulty in accurately adjusting the flatness of the glass due to the different sizes and complex curves of the glass in traditional installation methods, and significantly improves the installation quality and appearance of special-shaped glass curtain walls.

[0021] 2. Efficient and stable positioning and installation assistance: (1) Flexible adjustment of the tilt angle: The auxiliary device of the present invention is connected to an external crane via a connecting rod. Once the curved glass is firmly attached to the multiple vacuum cups, the electric telescopic rod can precisely adjust the tilt angle of the housing, allowing the glass to flexibly adapt to walls or other building structures at different angles. This flexible adjustment of the tilt angle allows installers to quickly adjust the glass's posture according to actual construction needs without the need for repeated disassembly and reinstallation, greatly improving installation efficiency. This advantage is particularly evident when faced with complex building structures and changing installation environments.

[0022] (2) Stable fixation in the air: The vacuum suction cup fixation method adopted by the present invention can provide stronger adsorption force and more stable fixing effect compared with traditional strap fixation. During the hoisting process, the glass is tightly adsorbed by multiple vacuum suction cups. Even when it is shaken in the air or disturbed by external forces, it can remain stable and will not shift or fall off. This not only effectively prevents the glass from being damaged by collisions with walls or other objects during the hoisting process, but also significantly reduces construction safety risks and ensures the safety of construction workers and the surrounding environment.

[0023] 3. Automatic control and intelligent operation: (1) PLC controller integrated management: The device of the present invention realizes the signal connection and centralized control of key components such as the electric telescopic rod, control integrated valve, air pump, reducer A, reducer B and electric push rod through the PLC controller. The PLC controller can automatically adjust the operating status of each component according to the preset program and sensor feedback information to realize the automated operation of the entire device. For example, during the installation process, the PLC controller can automatically adjust the speed and direction of reducer A and reducer B according to the size and shape of the glass, accurately control the position and adsorption force of the vacuum suction cup; at the same time, it automatically adjusts the telescopic length of the electric telescopic rod according to the relative position of the glass and the wall, and realizes the rapid positioning and installation of the glass. This automated control method not only improves the installation efficiency and accuracy, but also reduces the tediousness and errors of manual operation, making the entire installation process more intelligent and efficient.

[0024] (2) Reduced labor costs and labor intensity: Since the present invention automates most installation operations, the skill requirements for operators are greatly reduced, and ordinary workers can become proficient in operation after simple training. At the same time, the automated control system can accurately execute various operating instructions, reducing the need for manual adjustment and repeated calibration, significantly reducing labor intensity and labor costs. This cost advantage is particularly evident in large-scale construction projects and can bring considerable economic benefits to enterprises.

[0025] 4. Wide applicability and flexibility: (1) Adaptability to various glass types: The device of the present invention can adapt to special-shaped glass of different sizes, shapes, and curvatures. Whether it is simple curved glass or complex three-dimensional free-form glass, precise installation can be achieved by adjusting the position and suction force of the vacuum suction cup. This wide applicability makes the present invention play an important role in various types of building curtain wall projects. In particular, in modern architectural design, more and more buildings use unique special-shaped glass curtain walls. The present invention can meet the construction requirements of these complex designs and provide strong support for the innovation of building appearance.

[0026] (2) Flexible response to changes in the construction environment: During the actual construction process, the construction site environment is complex and changeable, and may be affected by factors such as weather and site space. The device of the present invention can quickly adapt to these changes due to its automated control and flexible adjustment capabilities. For example, when installing glass in a small space, the operating parameters of the device can be flexibly adjusted through the precise control of the PLC controller to achieve accurate positioning and installation of the glass; in severe weather conditions, the automated control system can ensure the stability and safety of the installation process and reduce errors caused by human factors. This flexibility enables the present invention to maintain efficient and stable performance in various construction environments, and has strong practicality and market competitiveness.

[0027] 5. Improve construction quality and safety: (1) High-quality installation: Through precise flatness adjustment, multi-point adsorption fixation, and flexible tilt angle adjustment, the present invention can significantly improve the installation quality of special-shaped glass curtain walls. The flatness of the glass is guaranteed, the appearance is more beautiful, and the sealing performance is also improved, effectively preventing problems such as rainwater leakage. The high-quality installation effect not only improves the overall quality of the building, but also extends the service life of the glass curtain wall and reduces subsequent maintenance costs.

[0028] (2) Reduced safety risks: In traditional installation methods, glass tends to shake during the hoisting process, posing a high safety risk. The present invention ensures the stability of the glass during the hoisting process through the firm adsorption of the vacuum suction cup and the precise adjustment of the electric telescopic rod, reducing the safety hazards caused by glass shaking. At the same time, the introduction of the automated control system further reduces the possibility of human operational errors and improves the safety of the construction process. In construction, safety is always the primary consideration, and these safety features of the present invention make it more advantageous in practical applications. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the shell 1 is respectively fixedly installed with a PLC controller and a rechargeable battery pack 11, and the air pump 10 is operated to exhaust multiple vacuum suction cups 5, and then the vacuum suction cups 5 can adsorb and fix the glass under negative pressure.

[0034] See also Figure 8 A speed reducer A41 is fixedly installed inside the extension arm 4. A reciprocating screw 42 is fixedly installed at the output end of the speed reducer A41. The outer side of the reciprocating screw 42 is threadedly connected to a screw sleeve 43. A ball joint 44 is fixedly installed at the bottom of the screw sleeve 43. A ball joint head 45 is hinged to the inner wall of the ball joint 44. The bottom of the ball joint head 45 is fixedly installed with the vacuum suction cup 5. The speed reducer A41 can drive the reciprocating screw 42 to rotate, and then the screw sleeve 43, ball joint seat 44 and ball joint head 45 are horizontally displaced. The vacuum suction cup 5 can use the ball joint seat 44 and ball joint head 45 to change the curvature of the glass.

[0035] See also Figure 7 The drive assembly 7 includes a reducer B71, which is fixedly mounted on the inner wall of the housing 1. The output end of the reducer B71 is fixedly mounted with a shaft 72, which is fixedly mounted to the sleeve at the end of the extension arm 4. The output shaft of the shaft 72 is mounted with a cross-axis universal joint 73, and the other end of the cross-axis universal joint 73 is connected to the end of the other extension arm 4 through the shaft 72. The reducer B71 can drive the shaft 72 to rotate, and the shaft 72 drives the other shaft 72 to rotate synchronously through the cross-axis universal joint 73, thereby controlling the synchronous rotation of the two extension arms 4 on one side to adjust the angle.

A pawl 82 is engaged with the side of the ratchet ring 81. The bottom of the pawl 82 is movably mounted on the inner wall of the housing 1 through a fixed hinge seat 83. A torsion spring 84 is mounted on the hinge shaft of the fixed hinge seat 83.

The torsion spring 84 allows the pawl 82 to be continuously inserted into the ratchet ring 81. The arrangement of the pawl 82 and the ratchet ring 81 ensures that the extension arm 4 will not be resisted when it rotates close to the glass. On the contrary, after the vacuum suction cup 5 absorbs the glass and lifts it, the four extension arms 4 will be subjected to force, and the arrangement of the pawl 82 and the ratchet ring 81 ensures that the extension arms 4 will not rotate or slip out of the position after being brought close together.

The electric push rod 88 is embedded in the interior of the housing 1. When the extension arm 4 needs to be rotated back to its original position, the electric push rod 88 pushes the cross bar 87 outward, and the cross bar 87 pulls the soft rope 85 through the slide bar 86. The soft rope 85 pulls the pawl 82 away from the ratchet ring 81, and the pawl 82 and the ratchet ring 81 are no longer restricted and locked, thereby controlling the rotation of the extension arm 4 back to its original position.

[0038] The electric telescopic rod 3, the control integrated valve 9, the air pump 10, the reducer A41, the reducer B71 and the electric push rod 88 are all connected to the PLC controller signal.

[0039] Example 2: A method for using the flatness-adjustable positioning auxiliary device for a special-shaped glass curtain wall as described in Example 1 comprises the following steps: S1, connect the device to the external crane through the connecting rod 2; S2, the crane controls the extension arm 4 to approach the curved glass 6, so that the three vertical vacuum suction cups 5 are adsorbed on the surface of the curved glass; S3 and the reducer B71 drive the shaft 72 and the cross-axis universal joint 73 to rotate, so that the extension arms 4 on both sides move closer to the curved glass 6 until all four vacuum suction cups 5 are adsorbed on the curved glass; S4, the air pump 10 starts to operate, and the vacuum suction cup 5 is evacuated by controlling the integrated valve 9 and the hose, so that the vacuum suction cup and the curved glass are tightly adsorbed under negative pressure; S5, reducer A41 drives the reciprocating screw 42 to rotate, so that the screw sleeve 43, ball joint seat 44, ball joint head 45 and vacuum suction cup 5 move to adapt to the size of the curved glass; S6, the vacuum suction cup 5 adapts to the curved surface of the glass through the ball joint seat 44 and the ball joint head 45; S7, adjusting the tilt angle of the housing 1 by the electric telescopic rod 3 so that the curved glass fits the wall; S8. After the installation is completed, the air pump 10 stops running, the integrated valve 9 is controlled to open, and the vacuum suction cup 5 releases the curved glass; S9, the electric push rod 88 pushes the cross bar 87 outward, pulling the pawl 82 away from the ratchet ring 81 through the sliding rod 86, unlocking the extension arm 4; S10, the extension arm 4 returns to its original position, and the device is removed to prepare for the next installation and use.

[0040] Both the A41 and B71 reducers are programmable reducers, and their speed and direction can be precisely controlled by a PLC controller. The adsorption force of the vacuum suction cup 5 can be adjusted by controlling the integrated valve 9 to adapt to curved glass of different sizes and shapes.

[0041] The telescopic length of the electric telescopic rod 3 can be accurately controlled by a PLC controller to achieve multi-angle adjustment of the housing 1.

[0042] The entire operation process of the adjustable flatness positioning auxiliary device for special-shaped structural glass curtain walls can be automatically controlled by a PLC controller, reducing manual intervention.

[0043] When in use, it is connected with the external crane in advance through the connecting rod 2, and then the crane controls the four extended arms 4 to approach the curved glass 6, first allowing the three vertical vacuum suction cups 5 to adsorb the shell 1 on the surface of the curved glass 6, and then the reducer B71 drives the shaft 72 and the cross-axis universal coupling 73 to rotate, and then the extended arms 4 on both sides move closer to the curved glass 6 until the four vacuum suction cups 5 are adsorbed on the curved glass 6, and then the air pump 10 is operated to make the vacuum suction cups 5 and the curved glass 6 tightly adsorbed under negative pressure; when the curved glass 6 is adsorbed by multiple vacuum suction cups 5, the inclination angle of the curved glass 6 can be adjusted through the electric telescopic rod 3, which is convenient for mutual adaptation with the wall. At the same time, the fixing method of the curved glass 6 of the present application ensures that the curved glass 6 will not shake in the air, thereby achieving the purpose of positioning and auxiliary installation of the curved glass 6.

[0044] In order to adapt to the size of the curved glass 6, the reciprocating screw 42 is driven to rotate by the reducer A41, and then the screw sleeve 43, the ball joint seat 44, the ball joint head 45 and the vacuum suction cup 5 are moved to facilitate the adaptation to the size of the glass; At the same time, the vacuum suction cup 5 can automatically adapt to the curved surface of the glass through the ball joint seat 44 and the ball joint head 45. This process achieves the purpose of adjusting and adapting the flatness of the curved glass 6.

[0045] After the installation is completed, the air pump 10 stops running, the control integrated valve 9 is opened, the gas leaks out, and the vacuum suction cup 5 has no adsorption force on the curved glass 6, so the device can be removed; in order to facilitate the next lifting of the curved glass, the electric push rod 88 is required to push the cross bar 87 outward, and the sliding bars 86 at both ends of the cross bar 87 slide on the surface of the shell 1, and then the soft rope 85 pulls the pawl 82 to leave the ratchet ring 81. At this time, the pawl 82 and the ratchet ring 81 are no longer locked, and the reducer B71 can be used to drive the shaft 72 and the cross-axis universal coupling 73 to rotate synchronously, and then the four extension arms 4 are rotated back to their original positions, so as to facilitate the adjustable positioning auxiliary installation of the next curved glass 6 with a different curve.
