Cleaning device applied to inner wall of petroleum pipeline

Abstract

The invention discloses a cleaning device applied to the inner wall of a petroleum pipeline. The cleaning device comprises a driving rod and a rotating disc fixedly connected with one end of the driving rod; the rotating disc and the driving rod share a same axis, a plurality of blind holes are circumferentially and evenly distributed on the outer circular arc face of the rotating disc, and a plurality of long-shaped holes are formed in the position, corresponding to the multiple blind holes, in the axial direction of the rotating disc; the long-shaped holes communicate with the correspondingblind holes, and the length direction of the communicating long-shaped holes are the same as the depth direction of the blind holes; and compression springs and abrasive-tool guiding rods are arrangedin the multiple blind holes, limiting pins are arranged in the radial direction of the abrasive-tool guiding rods, the two ends of the limiting pins are movably connected with the long-shaped holes,and friction plates are fixedly mounted on the top faces of the abrasive-tool guiding rods. According to the cleaning device applied to the inner wall of the petroleum pipeline, abrasive tools on therotating disc make close contact with the inner surface of a petroleum drilling pipe to remove iron rust on the surface of the inner wall of the petroleum drilling pipe in a friction mode, the quick rust removing effect can be achieved only through the fact that a worker hold a hand-held motor by hands to walk in the length direction of the petroleum drilling pipe, and the labor strength of rust removing by workers is reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a cleaning device applied to the inner wall of petroleum pipelines. Background technique [0002] Dirt and rust layers will form on the inner wall of the oil drill pipe for a long time before processing or after use. During equipment maintenance, the oil drill pipe needs to remove the dirt layer and rust layer on the inner wall. The operation of the prior art is manual Carry out grinding treatment to remove the dirt layer and rust layer. This method has the following disadvantages. The construction period is long, the construction personnel’s operation intensity is high, and the efficiency is extremely low. The time cost of removing an oil drill pipe is high, and other auxiliary equipment is required. Helping to rotate the oil drill pipe brings great resistance to the work of the workers, so it is urgent to seek a kind of oil drill pipe rust remover with high work eff...

[0002] Dirt and rust layers will form on the inner wall of the oil drill pipe for a long time before processing or after use. During equipment maintenance, the oil drill pipe needs to remove the dirt layer and rust layer on the inner wall. The operation of the prior art is manual Carry out grinding treatment to remove the dirt layer and rust layer. This method has the following disadvantages. The construction period is long, the construction personnel’s operation intensity is high, and the efficiency is extremely low. The time cost of removing an oil drill pipe is high, and other auxiliary equipment is required. It helps to rotate the oil drill pipe, which brings great resistance to the work of the workers, so it is urgent to find an oil drill pipe rust remover with high working efficiency and good derusting effect.
