Butted bracket for pipeline welding

Abstract

The invention discloses a butted bracket for pipeline welding. The butted bracket comprises a base, bottom plates and press plates, wherein two bearings are arranged in the central positions of the two side walls in the base, a moving rod and a threaded rotating shaft are movably mounted in the base through the bearings, the moving rod is located under the threaded rotating shaft, a limiting blockis arranged in the central position of the threaded rotating shaft, a first thread and a second thread are formed on the surface of the threaded rotating shaft, are mutually opposite and are mutuallysymmetric with the limiting block serving as a symmetry point, internal thread sleeves are arranged at the first thread and the second thread in a sleeving manner, stand columns are fixedly mounted at the tops of the two internal thread sleeves, and an opening is formed in the central position of the top of the base. By means a series of structures, the butted bracket has the characteristics of facilitating rapid fixation and rapid butt joint of pipe orifices.

Description

Technical field [0001] The invention relates to the technical field of pipeline welding, in particular to a butt joint bracket for pipeline welding. Background technique [0002] Welding, also known as welding and welding, is a manufacturing process and technology for joining metals by heating, high temperature or high pressure. Welding products are lighter than riveted parts, castings and forgings, and can reduce their own weight for transportation vehicles. , Save energy. The welding has good sealing performance and is suitable for manufacturing various types of containers. Develop joint processing technology to combine welding with forging and casting, which can produce large, economical and reasonable cast-welded structures and forging-welded structures with high economic benefits. The use of welding technology can effectively use materials, and the welding structure can use materials with different properties in different parts, giving full play to the advantages of variou...

Problems solved by technology

[0003] During the construction or production of metal pipes, it is usually necessary to adopt a mouth-to-mouth connection method, that is, to fix the two metal pipes by welding after the mouths of the metal pipes are butted, but the existing steel pipe welding device cannot be used for two different pipes. The steel pipe is quickly fixed, and the steel pipe is unstable on the device during welding, and it is prone to shaking, which makes the welding joint of the steel pipe uneven and the joint of the steel pipe is easy to loose. Therefore, in order to solve this series of problems, we propose a Butt brackets for pipe welding solve problems
