Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly, to a hoisting device applied to the installation of unit curtain walls. Background Art

[0002] The installation of unit curtain walls on building facades is an advanced and efficient exterior decoration construction technology in the current building field, demonstrating unique advantages. Its core component, the unit curtain wall, is an independent unit panel fabricated through a refined production process in a highly specialized factory environment. These panels integrate diverse panel materials such as glass, aluminum plates, and stone, and are ingeniously combined with stable structural components like aluminum alloy frames. Particularly crucial is that in the factory, the unit panels have fully completed key sealing processes such as waterproofing and airtightness, as well as the precise installation of opening fans, which significantly reduces the complexity and uncertainty of on-site construction. Through this factory prefabrication model, not only is the quality consistency and stability of each unit panel ensured, but also a solid foundation is laid for subsequent rapid and precise on-site installation, strongly promoting the advancement of building exterior decoration projects towards higher quality.

[0003] Under the current technical conditions, during the construction of unit curtain walls, the main process is to first lift the unit panels to the pre-set positions on the building facade using equipment such as cranes, and then precisely connect the unit panels with the embedded parts or post-embedded parts pre-installed on the main building structure by using the hanging parts or adapter parts installed on the edges of the unit panels. Most of the connection methods are bolt connections, slot connections, etc. However, this installation mode has drawbacks and is difficult to adapt when making rapid horizontal adjustments to the unit curtain wall, resulting in low installation efficiency. For example, in the unit glass curtain wall construction method disclosed in CN111255132A, a self-made mobile cantilever telescopic small cannon vehicle is used for operation. During the process of adjusting the horizontal position of the unit glass curtain wall, the small cannon vehicle needs to be frequently moved, which not only consumes time but also leads to low efficiency in transportation and the entire installation process.

The above-mentioned guiding track 5 is arranged above the above-mentioned vertical lifting structure and is arranged along the horizontal direction of the above-mentioned outer wall. The above-mentioned connecting piece is used for detachably connecting with the above-mentioned positioning component; a horizontal transportation structure arranged on the above-mentioned ground, the output end of which extends to the bottom position of the above-mentioned vertical lifting structure, and the input end extends to the storage area of the unitized curtain wall.

[0021] When the unitized curtain wall of the present application is hoisted, first, the horizontal transportation structure transports the unitized curtain wall from the storage area to the bottom of the vertical lifting structure. Then, accurately transfer the unitized curtain wall to the positioning component of the vertical lifting structure, start the first winch 6, and rely on the traction wire 4 to drive the positioning component to smoothly rise along the vertical cable wire 1, quickly sending the unitized curtain wall to the installation position above the outer wall. This process is efficient and stable. Subsequently, detachably connect the positioning component and the connecting piece, and by sliding the connecting piece on the horizontally arranged guiding track 5, the horizontal position of the unitized curtain wall can be finely adjusted to ensure the installation accuracy. Compared with the traditional crane hoisting, its advantages are obvious. On the one hand, the vertical lifting structure uses the cooperation of the cable wire 1 and the positioning component, can operate in a narrow space, is not restricted by the site, and the hoisting process is stable, reducing the risk of damage to the unitized curtain wall; on the other hand, compared with the traditional crane hoisting, it can quickly adjust the horizontal position, and at the same time can avoid the positioning deviation caused by the large swing of the traditional crane, ensuring the installation accuracy and improving the overall installation quality.
