An auxiliary equipment for overhead pipeline welding

Abstract

The invention relates to the technical field of auxiliary equipment for pipeline welding, in particular to auxiliary equipment for welding an overhead pipeline. The auxiliary equipment for welding the overhead pipeline is characterized in that the equipment is composed of a coarse positioning mechanism, a safety mechanism, a fine adjustment mechanism and a laser centering mechanism. The rising and falling function and the leftward and rightward movement function are achieved through the coarse positioning mechanism, so that the labor intensity of workers is relieved. The up-and-down fine adjustment function and the left-and-right fine adjustment function are achieved through the fine adjustment mechanism while the rising and falling function and the leftward and rightward movement function are achieved. A left laser emitting lamp, a right laser emitting lamp and a lower laser emitting lamp of the laser positioning mechanism are further arranged on the basis, three-point positioning is achieved through the three laser emitting lamps, the accurate pipeline centering function is achieved more accurately, and precise welding is achieved; meanwhile, the safety mechanism is arranged on a lifting rod of the coarse positioning mechanism, so that the safety of the whole structure is improved; the auxiliary equipment for welding the overhead pipeline has the advantages that labor is saved, operation is easy, the safety performance is high, the positioning accuracy and the centering accuracy are high, and the welding quality is high.

Description

technical field [0001] The invention relates to the technical field of pipeline welding auxiliary equipment, in particular to an overhead pipeline welding auxiliary equipment that saves manpower, is simple to operate, has high safety, high positioning and centering accuracy, and high welding quality. Background technique [0002] As we all know, the welding process in the construction of overhead thermal pipelines is one of the important processes. The quality of welding is related to the normal operation, life and safety and reliability of the pipe network. Therefore, welding quality control is one of the central links of quality control. Welding quality control and factors affecting welding quality, the relevant links must provide the necessary guarantee to ensure the welding quality, according to the technical requirements of the pipeline, equipment, personnel, site environment requirements and other conditions, use argon arc welding for the bottom, manual arc welding for ...

Problems solved by technology

The groove form of the butt joint is single-sided and V-shaped; emphasizing that the groove should be made according to the process requirements to ensure penetration. At present, many industries need to erect pipelines. Due to the limitation of ground and underground conditions, most departments choose overhead construction of pipelines. Under such circumstances, machinery cannot be used in the construction, and manpower must be completely relied on, and the amount of manpower is large, and the risk factor is large in the process of lifting
