Description

Technical Field

[0001] This utility model relates to the technical field of wall panel fine-tuning devices, and in particular to a prefabricated wall panel fine-tuning device based on ultra-low energy consumption green buildings. Background Technology

[0002] In today's society, with the acceleration of urbanization and the increasing awareness of environmental protection, ultra-low energy consumption green buildings have become an important trend in the construction industry. This trend not only aligns with national and global sustainable development concepts but is also a crucial measure to address the energy crisis and environmental pollution. Traditional construction methods have many drawbacks, such as energy waste, environmental pollution, high construction difficulty, and low efficiency, issues that are increasingly attracting attention. Ultra-low energy consumption green buildings, with their high energy efficiency, environmental sustainability, and other characteristics, have become an effective means of solving traditional building problems.

[0003] Prefabricated buildings, as an important form of ultra-low energy green buildings, have gradually gained market recognition and promotion in recent years. Prefabricated buildings, based on factory prefabrication and on-site assembly, achieve a highly efficient and precise mass production model. This prefabrication-assembly construction method not only improves construction efficiency and quality but also reduces damage to natural resources. However, in the assembly process of prefabricated buildings, the treatment of gaps between wall panels and the fine-tuning of the wall panels have become technical challenges. Improper gap treatment can affect the airtightness and thermal insulation performance of the building, while the fine-tuning of the wall panels is related to the overall precision and aesthetics of the building. The installation and adjustment of wall panels usually rely on manual operation, requiring installers to make rough adjustments using mechanical tools. While this method can meet basic requirements to a certain extent, it cannot meet the high requirements for precision and fine-tuning. Furthermore, manual adjustment is often unstable and prone to errors, easily causing gaps during wall panel assembly, affecting the thermal performance and structural safety of the wall.

[0004] Solving the aforementioned technical problems is the challenge facing this utility model. Utility Model Content

[0029] Furthermore, the auxiliary lifting mechanism 300 includes a lifting support frame 310 that cooperates with the transport base frame 100. The lifting support frame 310 is provided with a lifting frame 320.

The lifting base frame 200 is provided with a lifting and holding assembly 350 that cooperates with the other end of the lifting cloth 330.

[0030] Preferably, the structure of the lifting base frame is the same as the structure of the transport base frame.

[0031] Specifically, the lifting support frame 310 and the lifting frame 320 are the main structural parts of the auxiliary lifting mechanism 300. The lifting support frame 310 is connected to the transport base frame 100, and the lifting frame 320 is mounted on it. These components work together to support the operation of the lifting cloth 330, that is, to lift the wall through the lifting cloth 330. The lifting and retracting assembly 340 is responsible for controlling one end of the lifting cloth 330, driving the retracting roller 341 to retract the lifting cloth 330 through the retracting motor 342, thereby realizing the lifting action of the wall; while the lifting and holding assembly 350 manages the other end of the lifting cloth 330, ensuring that the lifting cloth 330 maintains the correct tension and position during the lifting process.

[0032] Preferably, the transport base 100 is provided with a plurality of lifting hydraulic cylinders 360 that cooperate with the lifting support frame 310.

The stabilizing roller 345 located below the retracting roller 341, in conjunction with the steering wheel 346, not only helps maintain the stability of the lifting fabric 330, but also guides the lifting fabric 330 to be correctly wound on the winding winch 343, ensuring a smooth lifting process.

[0036] Furthermore, the supporting cloth 330 includes a lifting cloth, with hanging pads at both ends. The hanging pads have hanging grooves. One end of the lifting cloth is wound by the winding winch 343 and engages with the hanging rod 344, while the other end is wound by the first winding roller 352 and the second winding roller 353 and engages with the stabilizing hanging rod 355. The hanging pads at both ends of the lifting cloth, with hanging grooves, facilitate connection with the hanging rod 344 or the stabilizing hanging rod 355. This design ensures that the supporting cloth 330 will not slip during lifting and also distributes the stress points, protecting the wall surface from damage.

[0037] Furthermore, the activity control component 600 includes a horizontal control frame 610 horizontally disposed on the transport base 100. The horizontal control frame 610 has a horizontal adjustment groove 620.

The telescopic direction of the telescopic control slide 650 is perpendicular to the sliding direction of the telescopic control frame 630.

[0038] Preferably, several movable adjustment components 600 are provided, and the telescopic adjustment carriages 650 in the several movable adjustment components 600 are connected to the same fine-tuning base 400.

[0043] First, the initial lifting of the wall is carried out. The wall is hoisted to the expected position of the building using hoisting equipment. The transport base frame 100 and the lifting base frame 200 are placed on both sides of the wall. The lifting hydraulic cylinder 360 drives the lifting support frame 310 to move upward along the lifting slide, so that the retractable roller 341 on the lifting frame 320 lifts one end of the lifting cloth 330 through the winding winch 343. At the same time, the other end of the lifting cloth 330 on the bottom of the wall cooperates with the lifting and holding assembly 350 on the lifting base frame 200. With the wall being hoisted by the hoisting equipment, the initial lifting of the wall is achieved.

[0044] Then, the wall is horizontally fine-tuned. The operator controls the fine-tuning base 400 to slide in the horizontal adjustment groove 620 of the horizontal adjustment frame 610 and the telescopic adjustment groove 640 of the telescopic adjustment frame 630 through the hand lever 500. The telescopic adjustment slide 650 drives the fine-tuning base 400 and the wall on it to move horizontally, so as to achieve fine-tuning of the wall position.

[0045] Finally, the fine-tuning base 400 is removed. After the wall is adjusted into place, the top support hydraulic rod 750 pushes the top support plate 760 upward, and the drop carriage 770 drives the lifting contact plate 780 to contact the bottom surface of the wall and lift it up. At the same time, the lifting screw 742 in the leveling screw unit 740 levels the stable base 720 through the leveling pad 743 to ensure the stability of the top support process. Subsequently, the top support slide 710 slides along the translational slide or smooth sliding frame, driving the auxiliary removal component 700 to move as a whole, so that the fine-tuning base 400 is smoothly removed from the bottom surface of the wall.
