Description

Technical Field

[0001] This utility model belongs to the field of curtain wall construction technology, and more specifically, it relates to a special hoisting tool for unitized curtain wall panels. Background Technology

[0002] Chinese patent application CN201922205609.3 discloses a unitized curtain wall hoisting tool, including a hoisting beam. A plate-shaped hanger is suspended below the hoisting beam. A transverse groove is provided at the upper end of the curtain wall panel for the plate-shaped hanger to slide. At least one end of the transverse groove is open for the plate-shaped hanger to enter. A limiting component is provided on the transverse groove to keep the upper limit of the plate-shaped hanger's vertical direction within the transverse groove. This utility model effectively solves problems related to asymmetrical hoisting points of curtain wall units, uneven tension on steel wire ropes, weak connection points, and low installation, dismantling, and hoisting efficiency. It also addresses issues such as material damage and deformation affecting the strength and functionality of curtain wall panels. Through detailed design of the upper part of the curtain wall panel and the coordinated use of the curtain wall hoisting tool, it ensures convenient, safe, and efficient installation of unitized curtain wall panels.

[0003] In actual high-altitude operation scenarios, the aforementioned utility model only uses adjustable bolts to vertically limit the connection between the hanger and the curtain wall panel, without designing a protective structure to address the risk of horizontal swaying during hoisting. During high-altitude hoisting operations, factors such as wind interference and vibrations from the start and stop of hoisting equipment can cause the curtain wall panel to sway horizontally. Prolonged vibration can easily loosen the adjustable bolts, potentially leading to relative displacement between the hanger and the curtain wall panel, and in severe cases, even causing the curtain wall panel to detach, posing a significant safety hazard.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a special hoisting tool for unitized curtain wall panels in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a special hoisting tool for unitized curtain wall panels, which is achieved by the following specific technical means: A special hoisting tool for unitized curtain wall panels includes a curtain wall panel. A hoisting mechanism is provided on the outer side of the curtain wall panel. The hoisting mechanism includes a first mounting plate. A horizontal anti-sway mechanism is provided on the side wall of the first mounting plate. The horizontal anti-sway mechanism includes first mounting blocks installed at the four corners of the side wall of the first mounting plate. The two side walls of the four sets of first mounting blocks are connected to second connecting columns. The outer walls of the two sets of second connecting columns are fitted with sliding blocks and second springs. The tops of the four sets of sliding blocks are rotatably mounted on the second mounting plate. The tops of the four sets of first mounting blocks are slidably mounted on the first connecting columns. The tops of the four sets of first connecting columns are connected to the corresponding side walls of the second mounting plates. The outer walls of the four sets of first connecting columns are fitted with first springs.

[0006] Preferably, a first connecting block is rotatably mounted on the top of each of the four sets of sliding blocks, a second connecting block is rotatably mounted on the top of each of the four sets of first connecting blocks, and the top of each of the four sets of second connecting blocks is connected to the side wall of the second mounting plate.

[0007] Preferably, contact wheels are rotatably mounted at all four corners on the other side of the second mounting plate.

[0008] Preferably, the hoisting mechanism further includes an adsorption plate disposed on the first mounting plate and adsorbed onto the outer wall of the curtain wall panel. A second mounting block is installed in the middle of the other side of the first mounting plate. An adjusting arm is rotatably mounted at the end of the second mounting block. A hoisting rope is connected to the top side of the adjusting arm. An angle adjustment mechanism that can cooperate with one end of the adjusting arm is provided on the side wall of the second mounting block.

[0009] Preferably, the angle adjustment mechanism includes a rotating pin that passes through and is installed at one end of the adjustment arm and on the side wall of the second mounting block. A gear is fixedly fitted on the outer wall of one end of the rotating pin. A rack is meshed on the side wall of the gear. One end of the rack is connected to an electric cylinder, which is installed on the side wall of the second mounting block.

[0010] Preferably, the adsorption plate is a vacuum rubber adsorption plate, the outer periphery of the contact wheel is covered with a silicone buffer sleeve, the surface of the silicone buffer sleeve is provided with anti-slip texture, and the outer periphery of the first connecting post and the second connecting post are both provided with an anti-corrosion coating, which is a zinc-aluminum alloy coating.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses a first connecting column and a first spring in combination. The first spring can generate elastic deformation as the curtain wall panel shakes, and the elastic force can offset the horizontal impact force. Combined with the rolling contact of the contact wheel and the curtain wall panel, it has the advantages of avoiding hard friction damage to the surface of the curtain wall panel, providing a reverse limiting force in real time, and enhancing the horizontal anti-sway capability. It avoids the swaying of the curtain wall panel caused by wind and vibration of the lifting equipment, and has the advantages of greatly reducing the risk of high-altitude displacement of the curtain wall panel and improving the safety of hoisting. 2. This utility model utilizes a silicone buffer pad mounted on the first mounting plate in conjunction with the curtain wall panel. The silicone buffer pad effectively isolates the direct contact between the first mounting plate and the curtain wall panel, thus preventing friction and collisions caused by shaking during installation, docking, and hoisting. This prevents scratches on the curtain wall panel surface, maintaining its integrity and significantly reducing subsequent repair and maintenance costs, improving overall construction efficiency and economy. Furthermore, through the coordinated use of the electric cylinder, adjusting arm, and hoisting rope, the piston rod of the electric cylinder can be extended and retracted according to actual needs. This allows for flexible adjustment of the angle between the hoisting rope and the adjusting arm, ensuring the stability and precision of the hoisting process and further optimizing the flexibility and safety of the hoisting operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a special hoisting tool for unitized curtain wall panels, including a curtain wall panel 1. A hoisting mechanism is provided on the outer side of the curtain wall panel 1. The hoisting mechanism includes a first mounting plate 3. A horizontal anti-sway mechanism is provided on the side wall of the first mounting plate 3. The horizontal anti-sway mechanism includes first mounting blocks 4 installed at the four corners of the side wall of the first mounting plate 3. The two side walls of the four sets of first mounting blocks 4 are connected to second connecting columns 7. The outer walls of the two sets of second connecting columns 7 are fitted with sliding blocks 17 and second springs 8. The tops of the four sets of sliding blocks 17 are rotatably mounted on second mounting plates 9. The tops of the four sets of first mounting blocks 4 are slidably mounted with first connecting columns 5. The tops of the four sets of first connecting columns 5 are connected to the corresponding side walls of the second mounting plates 9. The outer walls of the four sets of first connecting columns 5 are fitted with first springs 6.

[0020] The top of each of the four sets of sliding blocks 17 is rotatably mounted with a first connecting block 18, the top of each of the four sets of first connecting blocks 18 is rotatably mounted with a second connecting block 19, and the top of each of the four sets of second connecting blocks 19 is connected to the side wall of the second mounting plate 9. Through the rotatable connection and cooperation between the sliding blocks 17, the first connecting blocks 18, the second connecting blocks 19 and the second mounting plate 9, the second mounting plate 9 can flexibly adjust its posture according to the elastic buffering action of the horizontal anti-sway mechanism. This ensures the smooth linkage of the first spring 6 and the second spring 8 when they deform, avoids jamming between components that affects the anti-sway effect, and disperses the local stress generated by horizontal swaying through multiple sets of rotatable connections. This prevents structural damage caused by excessive force on a single connection point, extends the service life of the horizontal anti-sway mechanism, and improves the adaptability and buffering and limiting efficiency of the curtain wall panel 1 in the face of horizontal swaying.

[0021] The second mounting plate 9 has four contact wheels 10 rotatably mounted on each of its four corners. These contact wheels 10 can roll and adhere to the exterior wall of the building during hoisting. On the one hand, they provide horizontal support for the curtain wall panel 1 by contacting the exterior wall, directly limiting the swaying of the curtain wall panel 1 away from the exterior wall and preventing it from deviating from the hoisting path, thus ensuring the safety of high-altitude hoisting. On the other hand, the rolling characteristics of the contact wheels 10 allow them to move smoothly along the exterior wall as the curtain wall panel 1 is hoisted vertically, without hindering the hoisting process. Compared with sliding contact, this significantly reduces frictional damage to the exterior wall of the building. At the same time, the four-corner distribution design of the contact wheels 10 can balance the horizontal force on the curtain wall panel 1 from multiple directions, further enhancing the stability of the hoisting.

[0022] The hoisting mechanism also includes suction cups 2 mounted on the first mounting plate 3 and attached to the outer wall of the curtain wall panel 1. A second mounting block 11 is mounted on the middle of the other side of the first mounting plate 3. An adjusting arm 12 is rotatably mounted on the end of the second mounting block 11. A hoisting cable 13 is connected to the top side of the adjusting arm 12. An angle adjustment mechanism that can cooperate with one end of the adjusting arm 12 is provided on the side wall of the second mounting block 11. The suction cups 2 and the curtain wall panel 1 are attached together to achieve quick and stable initial fixation of the first mounting plate 3 and the curtain wall panel 1 without the need for drilling or welding on the surface of the curtain wall panel 1. The first mounting plate 3 is used to avoid damaging the structural integrity and surface aesthetics of the curtain wall panel 1. The second mounting block 11 provides stable rotation support for the adjusting arm 12. In conjunction with the connection between the adjusting arm 12 and the hoisting cable 13, the tension of the lifting equipment can be evenly transmitted to the first mounting plate 3, preventing local stress concentration from causing deformation of the curtain wall panel 1. The angle adjustment mechanism, in conjunction with the adjusting arm 12, can flexibly adjust the angle between the hoisting cable 13 and the adjusting arm 12 to adapt to the hoisting position requirements of different heights and angles. There is no need to manually adjust the position of the sling, reducing the intensity of high-altitude operations and improving the accuracy of hoisting.

[0023] The angle adjustment mechanism includes a rotating pin that runs through one end of the adjusting arm 12 and the side wall of the second mounting block 11. A gear 14 is fixedly mounted on the outer wall of one end of the rotating pin. A rack 15 is meshed with the side wall of the gear 14. One end of the rack 15 is connected to an electric cylinder 16, which is mounted on the side wall of the second mounting block 11. The electric cylinder 16 drives the rack 15 to move, and the meshing transmission between the rack 15 and the gear 14 drives the rotating pin to rotate, thereby controlling the rotation of the adjusting arm 12. This achieves automated and precise adjustment of the hoisting angle. Compared with manual adjustment, this is not only more efficient but also avoids angle deviations caused by manual operation, ensuring that the curtain wall panel 1 always maintains a horizontal hoisting posture and reducing the risk of collision or detachment of the curtain wall panel 1 due to angle imbalance. At the same time, the meshing transmission structure of the gear 14 and the rack 15 has the characteristics of smooth transmission and uniform force distribution, which can effectively transmit the driving force of the electric cylinder 16. Moreover, all components are mounted on the side wall of the second mounting block 11, resulting in a compact structure that does not occupy additional hoisting space and is suitable for high-altitude and narrow working environments.

[0024] The suction plate 2 is a vacuum rubber suction plate, and the outer periphery of the contact wheel 10 is covered with a silicone buffer sleeve with anti-slip texture. The outer periphery of the first connecting column 5 and the second connecting column 7 are both covered with an anti-corrosion coating, which is a zinc-aluminum alloy coating. The vacuum rubber suction plate 2 can enhance the adhesion and sealing with the surface of the curtain wall panel 1, improve the suction force, and prevent the suction from falling off due to wind or vibration. It also has a certain degree of elasticity to adapt to the slight curvature error of the surface of the curtain wall panel 1 and ensure stable suction. The silicone buffer sleeve on the outer periphery of the contact wheel 10 can further buffer the collision force between the contact wheel 10 and the exterior wall of the high-rise building, and prevent hard contact from causing damage to the wall or the contact wheel 10. The anti-slip texture on the surface can also increase the friction with the exterior wall and improve the contact stability. The zinc-aluminum alloy anti-corrosion coating on the outer periphery of the first connecting column 5 and the second connecting column 7 can form a dense protective film on the surface of the components, isolate the corrosive media such as high-altitude humidity, rainwater, and salt spray, prevent the components from rusting, extend the overall service life of the tool, and reduce maintenance costs and frequency.

[0025] The working principle of this embodiment is as follows: First, the hoisting mechanism, as the core connection and load-bearing carrier, places the first mounting plate 3 close to the outer wall of the curtain wall panel 1. The vacuum rubber adsorption plate 2 on its surface forms a negative pressure adsorption with the curtain wall panel 1, completing the initial fixation of the tool and the curtain wall panel 1. The pulling force of the hoisting equipment is transmitted to the adjusting arm 12 through the hoisting cable 13, and then transmitted to the first mounting plate 3 through the second mounting block 11, ultimately driving the curtain wall panel 1 to be hoisted synchronously. During hoisting, the horizontal anti-sway mechanism works in conjunction with the outer wall of the contact wheel 10 through multi-component linkage. The first mounting blocks 4 at the four corners of the first mounting plate 3 are connected to the second connecting columns 7 in pairs. When the curtain wall panel 1 is subjected to wind force or equipment vibration and causes horizontal swaying, the sliding block 17 on the outer wall of the second connecting column 7 slides along the column, squeezing or stretching the second spring 8 on the outer periphery. At the same time, the second mounting plate 9 drives the first connecting column 5 at the top of the first mounting block 4 to slide, causing the first spring 6 on the outer periphery of the first connecting column 5 to deform. The first spring 6 and the second spring 8 form a "lateral + oblique" double elastic damping, which, in conjunction with the rotation of the first connecting block 18 and the second connecting block 19 at the top of the sliding block 17, provides additional resistance. The linkage initially reduces the swaying amplitude; while the contact wheels 10 at the four corners on the other side of the second mounting plate 9 roll and adhere to the exterior wall of the high-rise building throughout the hoisting process. On the one hand, by abutting against the exterior wall, they provide horizontal external support for the curtain wall panel 1, directly limiting the swaying of the curtain wall panel 1 away from the exterior wall and preventing it from deviating from the hoisting path. On the other hand, the contact wheels 10 can roll along the exterior wall as the curtain wall panel 1 rises vertically, which does not hinder the hoisting process and can maintain horizontal stability through continuous rolling and adhesion. In addition, the silicone buffer sleeve on the outer periphery of the contact wheels 10 can avoid wall damage caused by hard contact with the exterior wall of the high-rise building, and the anti-slip texture on the surface can also enhance the friction with the exterior wall and further improve the reliability of the contact. In addition, the angle adjustment mechanism can be flexibly adapted to different hoisting positions: the electric cylinder 16 drives the rack 15 to move horizontally, and the rack 15 meshes with the gear 14 on the rotating pin at one end of the adjusting arm 12, thereby driving the adjusting arm 12 to rotate around the second mounting block 11, thereby adjusting the angle between the hoisting cable 13 and the adjusting arm 12 to ensure that the curtain wall panel 1 always maintains a horizontal posture.
