Drill stem inner wall cleaner facilitating fixing of friction part

Abstract

The invention relates to a drill stem inner wall cleaner facilitating fixing of a friction part. The drill stem inner wall cleaner facilitating fixing of the friction part comprises a hydraulic oil tank, wherein the output end of the hydraulic oil tank is connected with two fixed blocks symmetrically arranged, the inner sides of the two fixed blocks are connected through a spring, the natural length of the spring corresponds with the inner diameter of an oil drill stem, one end of each fixed block is outwards folded back to form a fixed groove, the other end of each fixed block is provided with a boss matched with the corresponding groove, the lower end of each boss is provided with a fixed block, one end of a scouring pad is provided with a groove matched with the fixed grooves and is arranged in the fixed grooves through the groove in a clamping mode, the other end of the scouring pad is provided with a clamping groove matched with the fixed blocks, and the fixed blocks are made of aluminum alloy. According to the drill stem inner wall cleaner facilitating fixing of the friction part is convenient to fix, by the action of clamping and fixing of both the groove and the boss, it is ensured that the scouring pad cannot fall out of the fixed blocks, and therefore the intractable dirt can be completely removed by the mutual friction between the scouring pad and the drill stem inner wall.

Description

technical field [0001] The invention relates to the field of cleaning devices, in particular to a descaling device for the inner wall of a drill pipe which facilitates the fixing of friction parts. Background technique [0002] In the process of oil extraction, the drill pipe is an indispensable tool. The drill pipe can be used repeatedly. In order to improve the service life of the drill pipe, the drill pipe must be maintained and cleaned after each use. After the drill pipe is used for a long time, the inner wall of the drill pipe is prone to rust, and a large amount of drilling fluid solid particles and oil stains will adhere to it. The dirt on the inner wall of the drill pipe will affect the next use of the drill pipe. The drill pipe with debris attached will affect the quality and work efficiency of the next drilling. The dirt will also corrode the inner wall of the drill pipe and seriously affect the quality of the drill pipe. Therefore, the inner wall of the drill p...
