Description

Technical Field

[0001] The invention belongs to the field of intelligent pre-assembly of catenary boom arms, and particularly relates to a flexible automatic coding and cutting device for catenary boom arm pipe fittings with a speed of 350 km / h. Background Art

[0002] There are strict process standards for the cutting of boom arm pipes and support pipes. At present, there is no professional cutting platform for boom arm pipes and support pipes on the market, and each construction unit adopts different methods. Traditional methods have difficulties such as the inability to highly unify the process standards of parts, insufficient measurement and cutting accuracy, and lack of information management throughout the life cycle. It is necessary to further improve work efficiency and unify standards, specifically including the following points:

[0003] 1. For the cutting of raw materials of boom arm pipes and support pipes in traditional pre-assembly workshops, generally 3 - 4 commonly used standard length pipe fittings such as 2.6m, 2.8m, 3.0m, 3.4m or 14m long pipe fittings are used. During cutting, the raw materials with a length close to that of the boom arm pipe in the boom arm pre-assembly form are selected. The pipe fittings are manually picked up and aligned with the scale line on the cutting platform for manual marking and mechanical cutting. After cutting, they are manually picked up to the drilling platform for drilling, and then manually picked up to the pre-assembly platform for pre-assembly. This cutting method wastes a large amount of manpower and material resources in transportation.

[0004] 2. For the marking of the pre-assembly lengths of boom arm pipes and support pipes in traditional pre-assembly workshops, the raw materials are compared with the scale on the cutting platform, and marking and cutting are carried out according to the comparison position. The process error of manual marking and cutting according to the scale line is relatively large, and it varies from person to person, resulting in inconsistent process standards.

[0005] 3. In traditional pre-assembly workshops, there is no tracking QR code for boom arm pre-assembly information, or the QR code is manually printed and pasted on the boom arm pipe or the pillar. This method is prone to damage to the QR code, and after a long time, the information cannot be read through the QR code, because the boom arm pre-assembly information is easily lost and cannot be managed informatization throughout the life cycle.

[0006] In order to build high-quality high-speed railway catenary projects, improve construction process standards, reduce production labor input costs, and strengthen technical information management, it is urgently necessary to further develop a targeted automatic cutting operation platform for boom arm pipes and support pipes.
