Automatic drill pipe joint thread cleaning device

Abstract

The invention relates to the technical field of drill rod cleaning devices, and discloses an automatic drill rod connector thread cleaning device. The automatic drill rod connector thread cleaning device comprises a cleaning base, a feeding device, a rotating device, a left walking device and a right walking device. The left walking device and the right walking device are fixedly installed on the left-end top and the right-end top of the cleaning base respectively, wherein an internal-thread cleaning device is fixedly installed on the left walking device, and an external-thread cleaning device is fixedly installed on the right walking device through a horizontal pipe. The automatic drill rod connector thread cleaning device is reasonable and compact in structure and convenient to use and has the advantages of being safe and convenient and fast to use; the cleaning base, the rotating device, the feeding device, the left walking device and the right walking device can be used in cooperation with one another to automatically clean internal threads and external threads of a drill rod connector; the cleaned threads of the drill rod connector can meet checking and repairing technological requirements, waste oil produced after cleaning can be recycled, operation is facilitated, cleaning efficiency is improved, and labor intensity of operating personnel is alleviated.

Description

technical field [0001] The invention relates to the technical field of drill pipe cleaning devices, and relates to an automatic thread cleaning device for drill pipe joints. Background technique [0002] Drill pipe is an important tool that must be used in the drilling process. It has been operated for a long time under complex geological conditions such as high temperature, high pressure, and high sulfur content in the downhole. Stress can easily lead to wear and failure. Therefore, in order to effectively ensure later drilling production and downhole safety, it is necessary to regularly pull the drill pipes at the drilling site back to the pipe company for inspection and repair. After the drill pipe was used by the drilling team, the thread of the joint was covered with mud and oil, and the metal background color could not be seen, so the degree of wear of the thread of the joint could not be judged. Therefore, after the drill pipe is pulled back to the pipe company, the ...
