Problems solved by technology

[0004] 1) Traditional welding is often done by welders with electric welding skills. The welding efficiency is low, the skills required for workers are high, the welding quality is unstable, the labor intensity is high, and the toxic fumes of welding are large, which affects the health of workers. There are fewer and fewer workers engaged in electric welding, and it is becoming more and more difficult to recruit electric welders, especially high-skilled electric welders. The salary of electric welders is getting higher and higher, which increases the labor cost of construction enterprises
[0005] 2) Tools such as positioners and sliding tables that are often used in the factory are often inconvenient to carry and are fixed for use in the factory. So far, no one has developed a pipeline welding equipment suitable for field construction.
The steel pipes that need to be welded on site often cannot be turned over. On the one hand, it is inconvenient to turn over when the diameter is large and the volume is large. turn over

Embodiment 1

[0052] Embodiment 1: see Figure 1 to Figure 12 .

[0053] An intelligent welding device with double welding torches for large-diameter steel pipes, including a circular ring assembly, a circular trolley 2, an axial moving part I 31, an axial moving part II 32, a radial moving part I 41 and a radial moving part II 42;

[0054] A ring assembly includes two half ring assemblies 1, and a half ring assembly 1 includes a half ring 11, a flange plate 12, support bolts 13 and two half ring gears 14, and the outer arc surface of the half ring 11 Fitted with the inner arc surface of the half ring gear 14, the two are fixedly connected with the axis line, and the end faces parallel to the axis line direction are aligned; the flange plate 12 is fixed on the half ring 11 parallel to the axis line direction On the end face: the two pairs of end faces parallel to the axial direction of the two semi-circular ring components 1 are respectively fitted together and the adjacent flange plates 12 ...

Embodiment 2

[0077] Example 2: see Figure 13 , is the situation of the welding intersecting curve of the intelligent welding equipment with double welding torches for large-diameter steel pipes. The large-diameter steel pipe I 51 and the large-diameter steel pipe III 53 vertically intersect and run through, and the intersection line is the intersecting line. Diameter steel pipe I 51 moves in a circular direction under the action of ring motor 25, moves parallel to the axis of large diameter steel pipe I 51 under the action of axial motor I 265, and moves in a direction parallel to the axis of large diameter steel pipe I 51 under the action of radial motor I 314. Next, move along the radial direction of the large-diameter steel pipe I 51, combined with the action of the swing motor I 414, the four motors coordinate their actions, and the welding torch I 417 can complete the welding of the weld near the circular trolley 2. Because it is difficult to coordinate the simultaneous work of two w...

Embodiment 3

[0078] Embodiment 3: see Figure 14 , is the situation of the welding intersecting curve of the large-diameter steel pipe double-welding torch intelligent welding equipment, the large-diameter steel pipe I 51 and the small-diameter pipe joint 54 vertically intersect and run through, and the intersection line is an intersecting line. The steel pipe I 51 moves in a circular direction under the action of the ring motor 25, moves parallel to the axis of the large-diameter steel pipe I 51 under the action of the axial motor I 265, and moves in the direction of the axis of the large-diameter steel pipe I 51 under the action of the radial motor I 314. Do the motion along the radial direction of the large-diameter steel pipe I 51, combined with the effect of the swing motor I 414, the welding torch I 417 can complete the welding of the weld around the small-diameter pipe joint 54 one week. Welding torch II 427 is idle. Other structures, functions and beneficial effects are the same a...

Abstract

The invention belongs to the technical field of welding equipment, and relates to outdoor large-diameter pipe welding equipment, in particular to large-diameter steel pipe double-welding-gun intelligent welding equipment. Two semicircular rings surround a large-diameter pipe to be welded in middle, and the axes are overlapped; an annular motor drives an annular car to rotate along a ring; an axial motor drives welding guns to move in a direction parallel to the axes; a radial motor drives the welding guns to move in the radial direction; and a swing motor I drives the welding guns to swing. The large-diameter steel pipe double-welding-gun intelligent welding equipment can finish annular welding lines, can realize multi-layer and multi-way welding and swing welding, is high in welding efficiency, and guarantees the quality stability. The large-diameter steel pipe double-welding-gun intelligent welding equipment reduces labors and the labor intensity, prevents occupational injury, solves the problem of welder shortage, reduces the labor cost, uses double welding guns to improve the working efficiency twice, can weld multiple curved welding lines, is flexible in carrying, and is suitable for outdoor construction and use.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and relates to a large-diameter pipeline welding equipment in the field, in particular to an intelligent welding equipment with double welding torches for large-diameter steel pipes. Background technique [0002] Steel pipelines are often used for long-distance transportation of crude oil, refined oil or natural gas, and the transportation distance can reach hundreds or thousands of kilometers. Most of the pipe diameters are more than 200mm, and the largest one is 3000mm now. Its starting point and end point are respectively connected with other oil companies such as oil fields and refineries. Most of the steel pipelines are laid in the wild, some are on the ground, some are underground, and some need to cross natural obstacles such as rivers, canyons, and seabeds. The length specification of the raw material steel pipe is generally six meters, nine meters or twelve meters. The irregu...
