Abstract

The invention belongs to the technical field of drill rods, especially a high-strength rib drill rod, which includes an outer rod, an inner rod movably installed inside the outer rod, a first connecting rod fixed on the inner rod, and a first connecting rod installed on the first connecting rod. The second connecting rod of the rod, the side of the limiting groove is provided with a thread groove opened on the outer rod; the outer rod and the inner rod are connected by connecting bolts, and the connecting bolts pass through the through The hole is connected with the thread groove; one end of the second connecting rod is provided with a groove, and the first connecting rod is installed inside the groove, and a fixing bolt is threaded on the second connecting rod, and the fixing One end of the bolt is set through the inside of the threaded hole; when the threaded leaves on the outside of the drill pipe are severely worn, the connection bolt is disassembled by rotating, so that the connection between the inner rod and the outer rod is lost, and the inner rod is removed from the inside of the connecting groove. Pull out and replace the outer rod to avoid direct scrapping of the whole drill pipe and save costs.

Description

technical field [0001] The invention belongs to the technical field of drill pipe equipment, and in particular relates to a high-strength rib drill pipe. Background technique [0002] Rib drill pipe belongs to the subdivision of geological helical drill pipes. Its specific characteristics are: the geological drill pipe is used as the rod body, and it is welded by prestressed winding plane helical blades; according to the type of helical blades, it can be divided into single helix, double helix and triple helix head spiral etc. [0003] This kind of drill pipe is generally used in the development of geology. By using the rib drill pipe to drill holes in the designated places on the ground, with the help of its own structure, the soil generated by drilling is discharged to the ground, so that Realize geological development. [0004] There are following problems in existing technology: [0005] 1. After the thread blades set on the outside of the drill pipe are worn out, the...
