Grinding device for welding seam in surface of petroleum pipeline

Abstract

The invention discloses a polishing device for the weld seam on the surface of an oil pipeline, which comprises a base on which a first driving mechanism, a first groove, and a positioning frame are arranged; A driven wheel is provided, a connecting rod is pierced on the driven wheel, a clamping block is provided on the connecting rod, a blind hole and an adjusting rod are arranged on the clamping block, the adjusting rod is inserted in the blind hole, and the first groove is provided with There is a second drive mechanism, the output shaft of the second drive mechanism is provided with a grinding disc, the positioning frame is provided with a second groove, a spring is arranged in the second groove, a support frame is provided on the spring, and a support frame is arranged on the support frame. Features rollers. The invention can efficiently grind the welding seam on the outer wall of the oil pipeline, reduce labor force, improve the grinding quality, and at the same time, can grind the welding seam to be flush with the outer diameter of the oil pipeline.

Description

technical field [0001] The invention relates to a grinding device, in particular to a grinding device for welding seams on the surface of petroleum pipelines. Background technique [0002] Petroleum, also known as crude oil, is a viscous, dark brown (sometimes greenish) liquid. There are oil reserves in parts of the upper crust. The nature of petroleum varies with the place of origin, the viscosity range is very wide, the freezing point varies greatly (30-60 degrees Celsius), the boiling point ranges from room temperature to above 500 degrees Celsius, it is soluble in many organic solvents, insoluble in water, but can form with water emulsion. However, the composition and appearance of oil in different oil fields can be greatly distinguished. Petroleum is mainly used as fuel oil and gasoline, and fuel oil and gasoline constitute one of the most important primary energy sources in the world. Petroleum is also a raw material for many chemical industry products such as solv...

Problems solved by technology

[0003] During the transportation of oil, the oil pipeline is an indispensable and important equipment. After the pipeline is welded, a weld seam will be formed. The weld seam needs to be polished to make the weld seam flush with the outer contour of the oil pipeline. At present, it generally relies on manpower It is time-consuming and laborious to wipe the welds on the outer wall of the oil pipeline with sandpaper one by one, and the wiping force is not easy to control. It is easy to polish the welds to unevenness, which affects the quality and appearance
