Description

The automatic outside weld system of pipeline all positon
Technical field
The present invention relates to welding machine outside a kind of welding field, more particularly to a kind of automatic outside weld system of pipeline all positon.
Background technology
With the development of oil, natural gas, chemical industry, the construction of China's long distance pipeline is intended to use bigbore height Strength linepipe, and automatic welding technique necessarily becomes one of mainstream of pipe-line construction with its distinctive efficient, high-quality, reliability, is The demand for development in following pipeline construction market is adapted to, it is imperative to grasp full automatic welding connection technology, and applies on a large scale In Pipeline, but backing welding, filling weldering are still welded with import equipment, with manual welding or STT semiautomatic weldings Connect based on technique.Existing outside weld trolley theory of mechanics is as shown in figure 8, mainly by welding torch clamping mechanism 7, car body 8, chassis mechanism 9th, telescoping mechanism 10, elevating mechanism 11, though above-mentioned existing outside weld picks and can provide user and have good welding machine effect, really It is real that there is progressive, but have been found that also there are some shortcomings in its structure in actual use, cause the existing outside weld Pick in practical application, fail to reach optimal using effect, its shortcoming is as follows:
1st, first, cable easily powers off.Since welding tractor needs by cable to carry out data transmission with control cabinet, and And transmission cable is in car body centre position, the cable of connection is distributed across one lateral surface of car body, in the course of work, welding unit Equipment axis can be surrounded to rotate, therefore, friction occurs with pipeline for cable and people easily touches cable in operation, makes Into cable damage or cause cable loosen or virtual connection.Welding tractor is unable to normal power supply and communication.
2nd, in addition, it has not been convenient to overhaul.Holder for welding gun, telescoping mechanism, lifting mechanism, chassis machine are contained in welding tractor Structure etc. is more complicated, and the appearance and size for causing welding unit is compact.Drive control plate installation and maintenance dismounting is compared on car body It is cumbersome, when welding unit breaks down, increase difficulty for maintenance, increase the repair time, influence construction efficiency.
Furthermore 3, posture of welding torch adjustment is comparatively laborious in welding process.Above-mentioned holder for welding gun is outer welding machine component Important component, is even more the full-automatic outer essential part of welding machine, lacks it, outer welding machine can not just complete weld job. It is in the influence important key point of welding quality in welding process.Welding holder is connected with telescoping mechanism (swing mechanism); Relatively time-consuming is adjusted in welding process, and often in welding, the time for needing to adjust and key point are missed in adjustment, it is easy to are caused Welding quality is unqualified, has an effect on construction efficiency.
4th, secondly as welding tractor uses built-in trolley driving unit, cause welding tractor overall weight excessive, to apply Worker person brings larger physical demands, influences speed of application.
5th, it is worth noting that welding tractor chassis pose adjustment causes trolley and track resistance is excessive and Caton phenomenon pole Welding quality is easily influenced, the design of chassis and track is important one.
6th, more it should be noted that swing mechanism, which slides to have some setbacks, cannot bear twisting resistance and lateral force.Influenced in welding process Welding quality equipment is unstable.
