Rotary protector for pipe tool

The utility model discloses a rotary protector for a pipe tool, which comprises a lower guiding cover and a wear resisting cover, wherein, the guiding cover can be fixed on a drill rod to rotate with the drill rod, and the wear resisting cover can be sheathed on the drill rod and positioned on the drill rod above the lower guiding cover. The wear resisting cover and the drill rod can be oppositely rotated, and the external diameter of the wear resisting cover is larger than the external diameter of the guiding cover. The external diameter of the wear resisting cover is smaller than the inner diameter of a technical sleeve pipe. The utility model is characterized in that the rotary protector for a pipe tool has the advantages of simple and compact structure, convenient installation and long service life. The isolation between the drill rod and the sleeve pipe is effectively achieved by the rotary protector for a pipe tool. The phenomena of abrasion and friction on the technical sleeve pipe can be relieved and even eliminated. The use under a well is safe. The external diameter of the wear resisting cover is increased without increasing friction force, and the lifting of a lower pipe column is not blocked. Compared with the traditional protecting hoop with a welding and wear resisting belt and a drill rod, the effect is greatly improved. For the cost, the preliminary account of an individual well is reduced by 60%. For the general popularization, the economic benefit is very large.
