Petroleum drilling rod outer surface cleaning device

Abstract

The invention relates to the technical field of petroleum equipment, and discloses a petroleum drilling rod outer surface cleaning device. The petroleum drilling rod outer surface cleaning device comprises a drilling rod body, the outer surface of the drilling rod body is provided with a first clamping ring in a sleeved manner, first motors are embedded on the upper side and the lower side of theleft side face of the first clamping ring, output shafts of the first motors are fixedly connected with rotating shafts through couplers, the ends, away from the first motors, of the rotating shafts are fixedly connected with rollers, the position, located on the left side of the first clamping ring, of the outer surface of the drilling rod body is sleeved with a second clamping ring, an annular sliding groove matched with the rollers is formed in the right side face of the second clamping ring, and the rollers are located in the annular sliding groove. According to the petroleum drilling rodouter surface cleaning device, removed dirt and iron rust can be collected, air pollution can be prevented, the whole device is high in transmission efficiency, slippage due to dirt and iron rust outside the drilling rod body can be avoided, and the capacity of the whole device for driving the petroleum drilling rod to move is higher.

Description

Technical field [0001] The invention relates to the technical field of petroleum equipment, in particular to a device for cleaning the outer surface of a petroleum drill pipe. Background technique [0002] A drill pipe is a steel pipe with a thread on the tail, which is used to connect the surface equipment of the drilling rig and the drilling and grinding equipment or bottom hole device at the bottom of the well. The purpose of the drill pipe is to transport the drilling mud to the drill bit and raise it together with the drill bit. To lower or rotate the bottom hole device, the drill pipe must be able to withstand huge internal and external pressure, distortion, bending and vibration. In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. The drill pipe is divided into kelly, drill pipe and There are three types of heavier drill pipes, and oil drill pipes are now used for drilling in the process of oil exploration. [0003] During long-...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for cleaning the outer surface of oil drill pipes, which has the advantages of stronger ability to drive oil drill pipes to move, and can collect and remove rust and dirt, etc., which solves the problem that oil drill pipes may not be able to Problems with normal movement and polluting the environment
