Auxiliary device for construction of petroleum conveying pipeline

Abstract

The invention discloses an auxiliary device for construction of a petroleum conveying pipeline, and relates to the technical field of pipeline construction. The auxiliary device comprises a supporting table, a pipeline supporting seat is fixedly connected between the upper ends of two adjacent lifting columns, a pipeline clamping seat is hinged to the upper surface of the pipeline supporting seat through a rotating shaft, a first semicircular sliding groove is formed in one side face of the pipeline clamping seat, and a second semicircular sliding groove is formed in one side face of the pipeline supporting seat; and the two ends of the first semicircular sliding groove communicate with the two ends of the second semicircular sliding groove correspondingly. According to the auxiliary device, through the design of the pipeline supporting seat, the pipeline clamping seat, a first semi-annular gear, a second semi-annular gear, a connecting rod and a driving gear, the welding continuity of welding equipment on the petroleum conveying pipeline is guaranteed, the structure is simple, the automation degree is high, the welding efficiency of the petroleum conveying pipeline is improved, and the problems that an existing clamp can only achieve the clamping work and cannot work easily, the welding process is tedious, and the welding continuity of a circular welding seam is poor are solved.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, in particular to an auxiliary device for construction of petroleum pipelines. Background technique [0002] Petroleum refers to gaseous, liquid and solid hydrocarbon mixtures, specifically divided into crude oil, natural gas, natural gas liquid and natural tar. Petroleum is mainly used as fuel oil and gasoline, and is also a product of many chemical industries, such as solutions, fertilizers, pesticides Raw materials such as insecticides and plastics, petroleum products have a very wide range of functions and functions in social and economic development, and their refined products have penetrated into all aspects of people's lives and are inseparable. With the development of oil exploration and extraction, the oil transportation industry is also gradually flourishing. The current method used for oil transportation is pipeline transportation, that is, laying multiple pipelines on th...

Problems solved by technology

[0004] The purpose of the present invention is to provide an auxiliary device for the construction of oil pipelines, through the design of the pipeline support seat, the pipeline clamp, the first half ring gear, the second half ring gear, the connecting rod and the driving gear, the existing fixture is solved. It can only perform clamping work, but when welding, in order to maintain the continuity of the welding, the staff needs to move continuously, the welding process is more cumbersome and the welding continuity of the circular weld is poor.
