[0002] Prefabricated wall panels are a type of prefabricated building component. They are manufactured in factories according to standardized designs and then transported to the construction site for assembly. Prefabricated wall panels have a wide range of applications, including residential, commercial, and industrial buildings. With technological advancements and increased environmental awareness, prefabricated construction is gradually becoming an important trend in the modern construction industry.

A lifting mechanism for controlling the raising and lowering of the solid column 3 is provided inside the hollow column 2. A clamping and limiting mechanism for securing the prefabricated wall panel is provided on the clamping plate 4. In this embodiment, the two hollow columns 2 are used to limit the side of the prefabricated wall panel and are suitable for prefabricated wall panels of different lateral dimensions. The structure described in this solution facilitates the hoisting of prefabricated wall panels of different sizes.
[0031] To ensure the clamping and holding of the prefabricated wall panel, in the above embodiment, preferably, the clamping and limiting mechanism includes a rectangular groove 403 located on the clamping plate 4, and a movable plate 402 slidably connected to the bottom plate of the rectangular groove 403. The movable plate 402 is rotatably connected to a drive screw a 405 via a screw seat. The drive screw a 405 is driven by a first servo motor 404, which is fixed to the side wall of the clamping plate 4. In this embodiment, the limiting groove 501 is used to limit the bottom and side edges of the prefabricated wall panel.
[0032] To ensure the stability of clamping the prefabricated wall panel, in the above embodiment, preferably, a guide limiting rod 401 is fixed on the side wall of the moving plate 402. The outer end of the guide limiting rod 401 extends out of the guide hole on the side wall of the clamping plate 4, and the guide hole is located on the same side wall as the first servo motor 404. In this embodiment, the guide limiting rod 401 effectively ensures the stability of the moving plate 402 in clamping the prefabricated wall panel.
[0033] To facilitate efficient and convenient adjustment of the vertical dimensions, in the above embodiments, preferably: the lifting mechanism includes a through groove 201 opened in the upper part of the inner cavity of the hollow column 2, a second servo motor 202 installed in the through groove 201, and a drive screw b203 installed at the power output end of the second servo motor 202. The drive screw b203 is rotatably connected to the solid column 3 through a screw seat.
[0034] A limiting groove 204 is provided on the inner wall of the cavity of the hollow column 2. A limiting block 205 is slidably connected in the limiting groove 204, and the limiting block 205 is fixed to the top of the side wall of the solid column 3.

[0039] In the above embodiments, all components are commercially available products.
[0040] The above-described structure is used as follows: By controlling the output of the third servo motor 106 to rotate, the drive screw c105 rotates, which in turn moves the two hollow columns 2 relative to each other. The lower end of the prefabricated wall panel is then placed in the rectangular slots 403 of the two clamping plates 4 and clamped by the moving plate 402. This allows for the clamping of prefabricated wall panels of different widths. Activating the second servo motor 202 rotates the drive screw b203, adjusting the position of the solid column 3 within the hollow column 2. This allows the upper end of the wall panel to be easily limited within the limiting slot 501 of the limiting plate 5. Activating the first servo motor 404 uses the drive screw a405 to adjust the position of the moving plate 402, allowing the moving plate 402 to vertically limit the prefabricated wall panel. Compared to existing prefabricated wall panel suspension mechanisms (such as nets or other prefabricated wall panels of a certain size corresponding to a single suspension mechanism), this device can limit and suspend prefabricated wall panels of different sizes.
