Description

Technical Field

[0001] The present invention relates to ship and bridge construction technology, and more particularly to a movable tire frame base used in bridge and ship construction and a use method thereof. Background Art

[0002] With the development of modern shipbuilding and bridge engineering, the construction of large ships, bridges and other steel structures has become an important task in the industry. Due to the complexity of the relevant steel structures, the segmented construction method has been widely used. This method not only improves construction efficiency but also reduces construction difficulty. However, the segmented construction process also faces a series of technical challenges. Especially in the design and layout of the supporting structure, whether it is a ship or a bridge, a stable and reliable supporting structure needs to be set up to facilitate subsequent forming, welding, lifting, docking and other related work. Traditional cradles generally use a fixed installation method, and specially customize different support structures for different sections and place the structure on site. The existing support structure has been fixed. When fine-tuning is required, the cradle cannot be adjusted in time, which easily affects the construction quality and progress of the ship and bridge sections.

[0003] In the current relevant technologies, the functions of the tire frame base are mainly concentrated on height adjustment and shape control adjustment. However, with the development of science and technology, various intelligent tire frames have sprung up like mushrooms after rain. The various intelligent tire frame solutions are incompatible with each other. A considerable portion of their bases are generally produced by on-site cutting, which is relatively arbitrary and the interchangeability of the produced components is poor, making future maintenance and replacement out of the question. At the same time, with the promotion of reusable tire frames, there is still a lack of effective solutions on how to quickly arrange and withdraw these tire frames. Summary of the Invention

[0004] In response to the defects existing in the prior art, the purpose of the present invention is to provide a movable tire frame base and a method of use for use in bridge and ship construction.
