Iron tower production process based on three-dimensional space lofting

Abstract

The invention discloses an iron tower production process based on three-dimensional space lofting. The iron tower production process includes the lofting procedure, the machining procedure, the trail assembling procedure, the batch machining procedure, the galvanizing procedure and the finished product detecting procedure, wherein the lofting is three-dimensional lofting based on CAD. The production process is reasonable in design, accuracy of components can be greatly improved, the machining period is shortened, work efficiency is improved, and production cost of an iron tower is reduced. Meanwhile, aeration oxidation, settling and biofilter process are conducted on waste water produced in a galvanizing workshop, and therefore waste water is recycled, and the iron tower production process has the advantages of saving the water resource, protecting the environment and reducing enterprise cost.

Description

technical field [0001] The invention relates to a production process of iron towers, in particular to a production process of iron towers based on three-dimensional space lofting. Background technique [0002] The power tower is a facility used to support overhead lines during high-voltage overhead line transmission. It can be divided into angle steel towers, steel pipe poles and steel pipe narrow base towers in terms of structure. Angle steel towers are generally used in the field, and steel pipe poles and steel pipe narrow base towers are mainly Use within the city. [0003] At present, in the production process of iron towers, the key process that affects product quality and accuracy is the review and stakeout of drawings. The labor-intensive ones are processing and galvanizing. Before the application of computer technology, it takes a lot of man-hours. For a long time, it can only prolong the working time, which will easily cause the fatigue of the production personnel...

AI Technical Summary

Problems solved by technology

[0005] (1) Since the manufacture of iron towers belongs to rough processing, it brings great difficulties to the accuracy of manual lofting. In addition, the size of the base tower is very large, resulting in a difference of a few millimeters that cannot be detected and detected by human eyes. To a large extent Affected work efficiency and dimensional accuracy

[0006] (2) After the correct size is calculated by hand, it is necessary to manually draw the rod diagram, board diagram, make the original table, the schedule, etc. This series of processes is time-consuming and inefficient, and at the same time, it is difficult to guarantee its accuracy

[0007] (3) It is difficult to achieve zero discharge of various wastewater (including degreasing water, acid, alkali, and washing wastewater) generated in the galvanizing workshop, which not only pollutes the environment, but also causes a great waste of water resources
