Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of large-diameter steel pipe welding in an integrated pipe gallery, and in particular to a large-diameter steel pipe weld butt joint system in an integrated pipe gallery. Background Art
[0002] During the construction of pipeline engineering, due to the large weight of the pipeline itself, lifting equipment is required to stabilize the pipeline to be welded at all times during construction, which requires too much space. In addition, large-diameter steel pipes are often encountered during pipeline construction, which leads to deviations when the welds of two large-diameter steel pipes are aligned, and the weld grooves of the steel pipes cannot be effectively aligned, and this error cannot be compensated by lifting tools. There are two main ways to align the welds of pipelines, namely, the lifting machinery cooperates with manual adjustment and professional matching equipment is used for adjustment. For the method of manual adjustment of the matching, the efficiency is very low, the influence of human factors is too large, and the space is small during construction, which is relatively unsafe; the pipeline matching device is a matching and weld adjustment device for steel pipe welding during pipeline construction. It has two functions at the same time: one is to adjust the weld gap required for welding during pipeline construction, and the other is that it can quickly match the welded pipeline and also has the function of fixing the pipeline to prevent the pipeline from moving during welding. At present, various types of pipeline matching devices on the market have not been widely used. The main reason is that the equipment is bulky, inefficient, cumbersome to operate, narrow scope of use, and the current price is relatively high. During construction, traditional construction tools are difficult to operate due to space constraints, and there are technical problems such as difficulty in matching and difficult to overcome weld adjustments during specific operations.
