Description

Technical Field

[0001] The utility model relates to the technical field of building construction machines, in particular to a heavy-load balancing hoisting device for a building construction machine and the building construction machine. Background Art

[0002] In the modern construction industry, with the acceleration of industrialization, especially the development of modular integrated construction (MiC) technology, the volume and weight of prefabricated components have increased significantly, which has brought great challenges to the traditional building material lifting system. For example, the unit weight of advanced prefabricated MiC products can be as high as 20 tons, far exceeding the lifting capacity of conventional tower cranes. Especially when these heavy components need to be accurately lifted from the top of the building, the existing lifting methods show obvious limitations.

[0003] At present, building construction machines generally use tower cranes (tower cranes) as the main material lifting equipment at construction sites. However, due to the design load limit of the tower crane and the working coverage of the boom, the overweight MiC products cannot effectively cover the entire construction area and there are safety risks caused by excessive load. At the same time, as part of the building construction machine, the structural characteristics of the Bailey platform truss determine that it has certain constraints on the spatial layout of the lifting operation, which further limits the working range and flexibility of the lifting device.

[0004] In addition, the existing connection method between tower cranes and hangers is mostly a single-point connection design. This method is easy to cause tilting during the lifting process when lifting MiC products whose center of gravity is inconsistent with the lifting point position, seriously affecting the safety and accuracy of the lifting, and is not conducive to the efficient and stable installation of MiC products on building construction machines.

[0005] In view of this, it is urgent to develop a lifting device that can adapt to heavy loads, has a wide coverage range and multi-point balance adjustment functions, so as to overcome the shortcomings of existing technologies in the lifting operations of large-scale prefabricated MiC products and ensure the safe and efficient progress of construction.

The driving mode of the walking platform and the lifting components are all driven by motor-driven wheels, which not only ensures the reliability of the drive but also realizes accurate and efficient movement and lifting control.

[0034] Finally, by setting guide columns on the hanger and corresponding conical sleeves on the lower surface of the trolley body, the shaking of the hanger can be limited during the lifting process, thereby improving the lifting accuracy and safety. At the same time, the introduction of mobile terminals for remote monitoring and control further improves the intelligence level and construction efficiency of the lifting operation.
