Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, specifically a prefabricated building wall panel hoisting device. Background Technology

[0002] Prefabricated construction, as a modern building model, involves the standardized production of some or all of the building components in a factory, followed by transportation to the construction site and assembly using reliable connection methods. This model offers significant advantages such as improved project quality, shorter construction periods, reduced environmental pollution, and labor savings. Among the various prefabricated components in prefabricated construction, building wall panels are a key component of the building's main structure and maintenance structure. The efficiency and safety of their hoisting process directly affect the overall construction progress and quality of the project.

[0003] The hoisting process of wall panels mainly relies on specialized hoisting equipment. However, existing hoisting equipment, especially hoisting devices for wall panels, often has certain limitations. Traditional hoisting devices are mostly fixed structures, and the angle and span between their booms are not adjustable. When facing non-standard rectangular or irregularly shaped wall panels with special angles, traditional fixed hoisting devices cannot evenly distribute the hoisting points and align them with the center of gravity of the wall panel. This causes the wall panel to tilt and sway during hoisting, which not only poses safety hazards but may also damage the wall panel itself or its embedded parts due to uneven stress. In addition, fixed hoisting devices occupy a lot of space when not in use, making transportation and storage extremely inconvenient and increasing warehousing and logistics costs. Therefore, there is an urgent need for a hoisting device that can flexibly adjust the angle to adapt to different shaped wall panels and is easy to store. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated building wall panel hoisting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution;

[0006] A prefabricated building wall panel hoisting device includes a first boom, a rotating connection structure, and a second boom. Two first booms are provided, connected by a rotating connection structure. A second boom is located inside each first boom, forming a telescopic boom. The first and second booms have equally spaced lifting holes. They are connected by bolt fixing assemblies installed within these holes. Lifting rings are welded to both the first and second booms, with upper lifting ropes attached to the rings. Lower lifting ropes are attached to the lifting holes of the first booms, and a U-shaped lifting device is connected to the bottom of the lower lifting ropes.

[0007] As a further embodiment of this utility model: the rotating connection structure includes an upper disk, a lower disk, and a hinge pin. The upper disk and the lower disk are respectively disposed above and below the two first booms. The upper disk and the first boom, as well as the lower disk and the first boom, are rotatably connected by the hinge pin.

[0008] As a further improvement of this utility model: the upper disc has a plurality of adjustment holes at equal intervals in an arc shape, and screws are installed in the adjustment holes. The screws are threadedly connected to the corresponding screw holes opened on the first boom.
