Petroleum pipeline support with size adjustable

Abstract

The invention discloses a petroleum pipeline support for size adjustment, and relates to the technical field of petroleum pipeline auxiliary equipment. The invention includes a pressure plate, a support plate arranged under the pressure plate, and an arc-shaped lower groove is arranged on the upper surface of the support plate. An arc-shaped upper groove corresponding to the arc-shaped lower groove is arranged under the pressing plate, an opening is set in the middle of the top of the arc-shaped upper groove, and two protrusions with holes are symmetrically arranged at the opening of the arc-shaped upper groove. The two protrusions with holes are detachably fixed by the bolt 2 and the lock nut 2, the left and right ends of the pressure plate are symmetrically provided with threaded holes a and threaded holes b, and the left and right ends of the support plate are symmetrically provided with threaded holes corresponding to the threaded holes a The strip-shaped hole a and the strip-shaped hole b corresponding to the threaded hole b, a rubber gasket with holes is arranged between the pressure plate and the support plate, and the bolt 1 and the lock are used between the pressure plate, the rubber gasket and the support plate. Tight nut-removable fixation. The invention has a simple structure and meets the requirements for laying oil pipelines of different sizes.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for petroleum pipelines, in particular to a support for petroleum pipelines for size adjustment. Background technique [0002] Petroleum is the artery of industrial development, and gasoline, kerosene, diesel, heavy oil and natural gas produced by petroleum refining are the main suppliers of current energy. At present, the world's oil and natural gas consumption accounts for about 60% of the total energy consumption. [0003] Petroleum is transported from the place of production to the place of consumption through pipeline transportation, waterway transportation, railway transportation and road transportation. Onshore oil transportation is mostly based on pipeline transportation. Oil pipelines can transport oil and natural gas stably for a long time. Oil pipeline transportation has the advantages of large volume, convenience, economy, little environmental damage, safety and reliabilit...

[0005] A utility model patent with the application number of 201520555148.1 and the application date of July 29, 2015 discloses a support for laying multiple oil pipelines. The utility model includes support plates, pressure plates, support plates, bolts and buried screws. At least two semicircular depressions are arranged on the upper part of the support plate, the upper ends of the two vertical plates are connected to the two ends of the support plate, and the lower ends of the two vertical plates are respectively provided with fixed plates, the vertical connecting plates at both ends of the support plate are respectively connected to the two vertical plates, and the middle part of the pressure plate is provided with The number of semicircular depressions matching the support plate and the corresponding semicircular protrusions are provided with a rubber anti-seismic layer on both the semicircular depressions and the semicircular protrusions. The fixed structure and bolts position and fix the oil pipeline. Although the displacement and wear of the oil pipeline are well prevented and the vibration during transportation is reduced, this utility model can only be used for a certain type of oil pipeline and cannot To meet the size and laying requirements of different oil pipelines, the oil pipeline support must be replaced when changing the pipeline model, resulting in certain economic losses

[0006] Another patent application number is 201611022717.1, and the invention patent with the application date of 2016.11.21 discloses a new type of oil pipeline support. The oil pipeline fixing position is provided with a spring leaf between the adjacent oil pipeline fixing positions, and an elastic support device is arranged between the fixing position and the base. Through the limiting plate, the oil pipeline fixing position and the elastic device, the two The distance between the limit plates is the same, and the fixed position of the oil pipeline and the spring support material are adjusted accordingly, which can adapt to different types of oil pipelines. However, the weight of the oil pipeline is relatively large, and it will compress the spring piece and the elastic support material after long-term use, causing the spring piece to be damaged. And the elastic support material loses its elasticity, which affects the stability of the structure, and long-term replacement of materials will cause huge economic costs
