Problems solved by technology
However, the address setting device in this invention is relatively expensive, and its use environment requirements are also relatively high. For harsh environments such as shipyards, it will affect its precise positioning; It is difficult to adjust the height of the tire frame within the scope of the existing technology, so the cost of this invention is relatively expensive, and the practical value of the project is limited to a certain extent

Embodiment Construction
[0037]The making and using of the embodiments are discussed in detail below. It should be understood, however, that the specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention. The expression of the structural position of each component such as up, down, top, bottom, etc. in the description is not absolute, but relative. These directional expressions are appropriate when the various components are arranged as shown in the drawings, but when the positions of the various components in the drawings are changed, these directional expressions are also changed accordingly.
[0038] Such as Figure 1-5 As shown in the figure, a numerically controlled lifting and lowering hull segment positioning tire frame square matrix includes N×M groups of positioning tire frames and control systems arranged vertically and horizontally to form the square matrix, wherein N is an integer greater than 1, and M...

The invention discloses a numerically controlled lifting and lowering hull segment positioning tire frame square array, which adopts a motor to drive a worm to rotate, the worm drives a turbine to rotate, the worm wheel drives a jacking screw to rotate, and the jacking screw drives a jacking guide rail to move up and down. In order to achieve accurate jacking and positioning of large-scale hull structure segments, the invention adopts a numerically controlled jacking device to replace the traditional steel frame for positioning through assembly and welding. The tire frame of the present invention adopts modular design and manufacture, and can quickly adjust the height positioning dimension of the tire frame square array with high precision, and is especially suitable for complex curved surfaces of relatively large hulls and offshore platforms, which can improve production efficiency and shorten the shipbuilding cycle.
Description
technical field [0001] The invention relates to a tire frame for segmented positioning of a hull, in particular to a square matrix of tire frames for segmented positioning of a hull with numerical control adjustment for lifting, and belongs to the field of shipbuilding equipment. Background technique [0002] In the process of ship construction, the tire frame is an indispensable process equipment for the assembly and welding of hull segments, and it is the shape membrane and workbench for manufacturing hull curved segments and curved three-dimensional segments. There are many types of tire racks, which can be divided into two categories: special tire racks and general tire racks according to their scope of use. In my country, most shipyards use fulcrum angle steel tire frames. In order to meet the requirements of specific segmented surface line types, this special tire frame needs to weld and cut steel fulcrums, which inevitably causes waste of steel. Under the condition of...
