Problems solved by technology

The existing wear-resistant ring is connected to the drill pipe through the joint, and the wear-resistant ring and the joint are connected in a direct nesting manner. During the rotation of the drill pipe, due to the friction between the wear-resistant ring and the drilled hole, the wear-resistant Relative rotation occurs between the ring and the joint, which not only affects the straightening of the drill pipe, but also reduces the reaming effect; during the drilling process of the drill pipe, the friction between the existing wear-resistant ring and the geology is small, resulting in the reaming effect not ideal

Embodiment Construction

[0009] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0010] See figure 1 , the present invention includes a wear ring 2 and a joint 1, the wear ring 2 has an internal thread 21, the joint 1 has an external thread 11 matched with the internal thread 21, the wear ring 2 and the joint 1 are connected by the internal thread 21 and the external The threads 11 are spirally connected; the outer wall of the wear-resistant ring 2 is evenly distributed with a plurality of grooves 22, and the grooves 22 are beneficial to the friction between the wear-resistant ring 2 and the geology, thereby improving the hole reaming effect.

[0011] The above description is an explanation of the present invention, not a limitation of the invention. For the limited scope of the present invention, refer to the claims. The present invention can be modified in any form without violating the spirit of the present inventio...

Abstract

The invention relates to a structure for connecting a wearing ring and a joint in a drill machine. The structure comprises the wearing ring and the joint and is characterized in that the wearing ring is in threaded connection with the joint; multiple grooves are evenly distributed in the outer wall of the wearing ring. The wearing ring and the joint are fixed in the threaded connection mode and the effects of aligning the drill rod and chambering with the wear-resisting ring are greatly enhanced. Due to the grooves in the outer wall of the wear-resisting ring, friction between the structure and the ground is facilitated and the chambering effect is further improved.

Description

technical field [0001] The invention relates to the field of geological exploration equipment, in particular to an auxiliary device for a drill pipe on a drilling rig. Background technique [0002] Drilling rig is an indispensable equipment in geological exploration. The drill pipe on the drilling rig has a cylindrical and long strip structure. The drill pipe is generally equipped with a wear-resistant ring. Its function is to straighten the drill pipe on the one hand, and to Conducive to reaming. The existing wear-resistant ring is connected to the drill pipe through the joint, and the wear-resistant ring and the joint are connected in a direct nesting manner. During the rotation of the drill pipe, due to the friction between the wear-resistant ring and the drilled hole, the wear-resistant Relative rotation occurs between the ring and the joint, which not only affects the straightening of the drill pipe, but also reduces the reaming effect; during the drilling process ...
