Oil drill rod inner surface polishing and dust removing device

Abstract

The invention discloses a oil drill rod inner surface polishing and dust removing device. The oil drill rod inner surface polishing and dust removing device comprises a mounting block, a laterally arranged supporting plate is arranged on one side wall of the mounting block, and a driving motor is arranged on the upper side wall of the supporting plate. A mounting groove is arranged in the mountingblock, the output shaft of the driving motor passes through the side wall of the mounting groove and is connected with a first rotating shaft, and a side, away from the driving motor, of the first rotating shaft is provided with a horizontally arranged screw. The mounting groove is provided with a laterally arranged sleeve rod, the sleeve rod is provided with a threaded cavity opening toward thebottom of the mounting groove, the screw is connected with the threaded cavity in a threaded mode, and two side walls of the mounting groove are symmetrically provided with two limiting grooves with opposite openings. The oil drill rod inner surface polishing and dust removing device can be used for polishing the inner wall of a drill rod, a polishing operation is stable, an effect is relatively good, and wastes after the polishing can be collected and processed.

Description

technical field [0001] The invention relates to the technical field of grinding and dust removal equipment, in particular to a grinding and dust removal equipment for the inner surface of oil drill pipes. Background technique [0002] The drill pipe is a steel pipe with a 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. In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. The drill pipe is divided into three types: kelly, drill pipe and heavyweight drill pipe. During the processing of oil drill pipe, the internal surface is polis...

AI Technical Summary

Problems solved by technology

In the process of oil and gas extraction and refining, the drill pipe can be used multiple times. The drill pipe is divided into three types: kelly, drill pipe and weighted drill pipe. During the processing of oil drill pipe, the internal surface is polished and repaired. It is an important part, but the existing grinding equipment has a poor grinding effect, and the debris after grinding cannot be processed
