Description

Technical Field

[0001] The utility model relates to the technical field of structure hoisting, in particular to a steel structure engineering structure hoisting device. Background Art

[0002] Steel structure engineering is a structural engineering mainly made of steel and is one of the main types of building structures. It is composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. During the construction process of steel structures, due to the large size and heavy weight of steel components, it is difficult to carry and install them manually. Structural lifting devices can safely and efficiently lift steel components to the designated location.

[0003] For example, publication number: CN218320221U discloses "a steel structure engineering structure lifting device", which includes a steel structure body, a first fixed plate and a second fixed plate. The first fixed plate is located on the top of the second fixed plate, and the steel structure body is located inside the first fixed plate and the second fixed plate. The right and left sides of the first fixed plate are respectively clamped with the first limit plate and the second limit plate, and the bottoms of the first limit plate and the second limit plate are clamped with the third limit plate and the fourth limit plate. Both sides of the top of the first fixed plate are fixedly connected with lifting rings, the left side of the first limit plate is threadedly connected to the first fixing mechanism, and the right side of the second limit plate is threadedly connected to the second fixing mechanism.

[0004] However, in the prior art, when using cranes, tower cranes and other lifting equipment to lift steel structure components, when lifting structural components with regular shapes, the center of gravity position is easy to determine, so that the lifting fixture device and the component can be accurately locked and fixed, and the component can be stably lifted using cranes, tower cranes and other lifting equipment. However, in the actual construction process, many steel structure components are special-shaped structures, and it is difficult for operators to accurately judge the center of gravity position of the structure. After the lifting fixture device is fixed to the component, the center of gravity of the component is likely to be biased toward one end of the fixture, resulting in the component and the lifting frame device being in a state where one end is higher and the other end is lower during the lifting process, which increases the risk of the lifting operation during the lifting process.
