Hand-held petroleum drill rod rust remover

Abstract

The invention discloses a hand-held petroleum drill rod rust remover which includes a casing, a motor, a secondary gear, a rotating wheel and a grinding tool. The front end of the casing is provided with a transmission portion which is in a disc shape, the transmission portion is provided with a first U-shaped notch, one end face of the transmission portion is provided with an annular notch, the rotating wheel is mounted on the annular notch of the transmission portion and includes a circular pipe body and wheel teeth, a notch is formed between an outer circle and an inner circle of the circular pipe body, the plurality of wheel teeth are disposed evenly on the circumference of the outer circle of the circular pipe body, the wheel teeth of the rotating wheel are in meshing transmission with the secondary gear, a rotor output shaft of the motor is provided with a primary gear, the primary gear is in meshing transmission with the secondary gear, and the grinding tool is disposed in the circular pipe body of the rotating wheel. The hand-held petroleum drill rod rust remover can achieve the effect of rapid derusting only by operating the rust remover by hand to walk in the length direction of a petroleum drill rod, the labor intensity of workers' rust removal is reduced, and the derusting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a hand-held oil drill pipe rust remover. Background technique [0002] The oil drill pipe is a steel pipe with threaded tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or the bottom hole device at the bottom of the drilling well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and together with the drill bit to raise, lower or rotate the bottom hole device. Drill pipe must be able to withstand enormous internal and external pressure, twisting, bending and vibration. Dirt and rust layers will form on the surface of oil drill pipes before surface treatment or after use for a long time. During equipment maintenance, the dirt and rust layers on the surface of oil drill pipes need to be removed. The operation of the prior art is manual Grinding with a hand-held grinder remove...

AI Technical Summary

Problems solved by technology

Dirt and rust layers will form on the surface of oil drill pipes for a long time before surface treatment or after use. During equipment maintenance, oil drill pipes need to remove the dirt and rust layers on the surface. The operation of the prior art is manual. Grinding with a hand-held grinder removes 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. Other auxiliary equipment 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 work efficiency and good derusting effect
