Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe lubrication, in particular to a lubrication device for the inner wall of a steel pipe. Background Art

[0002] The steel pipe has a hollow cross-section and its length is much larger than its diameter or circumference. It is used to transport fluids and powdered solids, exchange heat energy, and manufacture mechanical parts and containers. It is also an economical steel material. During the use of the steel pipe, the inner wall of the steel pipe needs to be lubricated. When lubricating the inner wall of the steel pipe, a lubrication device for the inner wall of the steel pipe is required.

[0003] In the prior art, there are the following problems:

[0004] Usually when lubricating a steel pipe, most of them are introduced into the inside of the steel pipe, and then the lubricating oil inside the steel pipe is applied with a brush. It is necessary to use a long rod to extend the brush into the steel pipe for application, which is troublesome. The existing solution is to tilt the steel pipe at a small angle, then introduce the lubricating oil into the inner wall of the steel pipe, and finally drive the steel pipe to rotate so that the lubricating oil is discharged along the inner wall of the steel pipe, thereby lubricating the steel pipe. However, when the existing steel pipe inner wall lubricating device introduces the lubricating oil into the steel pipe, since the lubricating oil is usually a viscous liquid, it is easy to cause a thicker lubricating oil to adhere to the inner wall of the steel pipe. It is necessary to use more lubricating oil to lubricate the inner wall of the steel pipe, which easily causes a waste of lubricating oil. At the same time, the existing steel pipe inner wall lubricating device can only lubricate one steel pipe, which is not convenient for lubricating multiple groups of steel pipes at the same time, so the efficiency of steel pipe inner wall lubrication is relatively general.
