A method for laying and installing oil pipelines

Abstract

The invention relates to a petroleum pipeline laying and mounting construction method, in particular to a petroleum pipeline laying and mounting construction device. The device comprises a crawler type moving chassis, a bearing platform plate fixedly mounted on the crawler type moving chassis, multiple ground-gripping supporting mechanisms fixed to the bearing platform plate, a lifting mechanism arranged on the upper end surface of the bearing platform plate, a feeding conveying mechanism arranged on the lifting mechanism and two self-clamping components arranged on the feeding conveying mechanism and used for clamping a petroleum pipeline; and the ground-gripping supporting mechanisms are distributed and mounted on the two opposite sides of the bearing platform plate. By the aid of the device, the safety during laying construction is improved, and the petroleum pipeline can be sent to the laying and mounting position conveniently and accurately.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, and specifically proposes a method for laying, installing and constructing petroleum pipelines. Background technique [0002] The oil pipeline is composed of oil pipelines and their accessories. According to the needs of the process, it is equipped with corresponding oil pump units, designed and installed as a complete pipeline system, and used to complete the tasks of oil loading, unloading and transportation; Compared with railway and road oil transportation, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. [0003] Oil pipelines often need to be installed on a laying installation frame for fixing. The laying installation frame has a certain height. Generally, hoisting equipment is often used for hoisting and laying during laying operations. However, there are obviously some disadvantages in lay...

AI Technical Summary

Problems solved by technology

[0004] 1) The installation road surface of oil pipeline transportation is complex, and it is impossible to have a flat and good road surface. During the long-distance laying and installation construction process, it is very inconvenient to use hoisting equipment to repeatedly transfer and hoist from the oil pipeline stacking area;

[0005] 2) The process of hoisting oil pipelines is a dangerous operation, and there are great safety hazards in the process of long-distance transshipment, and it is not easy to hoist the oil pipelines to the laying installation frame into the accurate position, and it is not easy to be well connected with them. The docking of the oil pipeline that has been installed and laid requires manual active adjustment for accurate alignment, and the adjustment range is sometimes large
