Description

Technical Field

[0001] The invention belongs to the technical field of steel structure processing, relates to operations of steel structure tire benchmarking, steel structure assembly, and welding positioning, and specifically relates to a steel structure three-dimensional benchmark working platform. Background Art

[0002] The existing steel structure manufacturing in the market is widely used in metallurgy, chemical industry, water conservancy, electric power, bridge, construction, and machinery manufacturing industries. In the steel structure industry, the manufacturing processes of steel structures are similar. Most of them are on a flat work platform, using marking assembly or tire making to assemble and weld the steel structure parts to be manufactured, and finally complete the steel structure product. However, this type of work platform usually only has horizontal requirements, some are larger, some are smaller, and some are just a bracket platform; and the existing steel structures are generally diverse in form. For the same components with a small number, they cannot be mass-produced, so the marking assembly method has been continued. For the same components with a large number, the tire membrane assembly method is adopted, and the steel structure tire membrane assembly method has many advantages, including: 1. It can effectively control the assembly accuracy of steel structure parts and product accuracy; 2. It can avoid assembly errors in steel structure assembly work; 3. It can improve the efficiency of steel structure assembly work.

[0003] Based on the above two steel structure assembly methods, a specific analysis is conducted. In the manufacturing process of steel structures, two assembly methods are usually used: (1) Marking assembly method. The marking assembly method is easily restricted and limited by the technical level of the assembly workers, and the structural linearity and dimensional errors fluctuate greatly, the work efficiency is low, and it is easy to make mistakes. (2) Membrane assembly method. Although the membrane assembly method has the advantages of controllable assembly accuracy and product accuracy, and the assembly work is not prone to errors and has high assembly efficiency, the preparation of the steel structure assembly membrane requires higher technical requirements for the steel structure membrane preparation workers. In addition, due to the limitations of measurement accuracy, technical worker level factors and preparation process, the accuracy of steel structure membrane production is not ideal. In actual work, there are very few skilled workers who have the ability to prepare membranes, the membrane structure accuracy is not ideal, and the steel structure membrane is single-pointed for finished components and is not universal. Summary of the Invention
