[0003] As one of the important links in the fabrication of offshore steel structures, pile pipe construction is mainly affected by three factors: one is manual or semi-mechanized operation, which not only has low work efficiency, but also has high labor intensity
Second, because offshore construction is greatly affected by the natural climate, the effective time of construction operations is very short. At the same time, various engineering ships are required to cooperate in the construction, and the project cost is very high.
[0004] Although the automatic welding currently used has replaced the original welding method and improved the welding efficiency of thick-walled pipes, it has increased labor intensity, production costs, and reduced the automation technology level, welding quality and efficiency of pile pipe welding.

Embodiment 2
[0035] In order to introduce the embodiment of the present invention more clearly, the following introduces it from the usage method of the embodiment of the present invention.
[0036] see Figure 4 First, the flexible track 11 is tightly hooped above the groove of the pile pipe; 2 sets of adjustable movable wheels and 2 sets of supporting walking wheels are respectively fixed on the four corners of the lower and upper sides of the bottom plate 17 with screws, and then The wheel grooves of the four wheels are clamped to the upper and lower edges of the flexible track 2, so that the bottom plate 17 is suspended on the flexible track 11, and the movable wheel and the supporting walking wheel are double-groove wheels, which can be passed smoothly at the joint of the flexible track 11. , and has the function of rotating in the radial direction, which can adapt to changes in the curvature of different pile tubes. The coupling is connected with the supporting walking wheel to cont...

The soldering flux bracket for pile pipe submerged-arc soldering comprises a first arc ring, a lock catch, a second arc ring, a first hinged piece, a second hinged piece and a third arc ring, wherein the first arc ring is in contact with a pile pipe, the lock catch is connected with the first arc ring, the second arc ring is connected with the first arc ring through the lock catch, the first arc ring is in contact with the pile pipe, the first hinged piece is connected with the first arc ring, the second hinged piece is connected with the second arc ring, one end of the third arc ring is connected with the first arc ring through the first hinged piece, the other end of the third arc ring is connected with the second arc ring through the second hinged piece, and an annular structure is defined by the first arc ring, the second arc ring and the third arc ring and clamped on the pile pipe. By means of the soldering flux bracket for pile pipe submerged-arc soldering, the submerged-arc soldering technology is smoothly applied to soldering operation of the pile pipe.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a flux bracket for submerged arc welding of pile pipes. Background technique [0002] In the offshore construction of the pile pipe, due to the thick wall and large diameter of the pile pipe, the welding workload is huge. However, at present, no matter at home or abroad, the welding of the pile pipe of the offshore oil platform jacket has been using manual arc welding for many years. Therefore, low-efficiency welding methods have restricted the development pace of the rapid growth of offshore oil platforms. [0003] As one of the important links in the fabrication of offshore steel structures, pile pipe construction is mainly affected by three factors: first, manual or semi-mechanized operation, which not only has low work efficiency, but also has high labor intensity. Second, because the offshore construction is greatly affected by the natural climate, the effective time of th...
