Description

Integral square head for rotary drilling rod

Technical Field

The utility model relates to a dig drilling rod accessory technical field soon, specifically indicate a dig drilling rod soon and use integral square head.

Background

The rotary drilling rod is a rod piece which is connected with a drill bit and used for transmitting power in a drilling tool. The drill pipe must be able to withstand large internal and external pressures, twists, bends and vibrations. The square head part of drilling rod is used for being connected with the drill bit, and the square head link links firmly with the core section, and at drilling rod during operation, the square head need bear great torsional force, and the square head link often can break.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a dig integral square head for drilling rod soon.

In order to solve the technical problem, the utility model provides a technical scheme is one kind and digs integral square head for drilling rod soon: the square head, the square head disc, the square head neck and the core joint butt joint pipe are integrally formed, and the axes of the square head, the square head disc, the square head neck and the core joint butt joint pipe are the same; the diameter of the core section butt joint pipe is the same as the outer diameter of the core section of the rotary drilling rod; the end, far away from the square head neck, of the core joint butt joint pipe is provided with a chamfer angle, so that the core joint butt joint pipe is in butt joint with the core joint conveniently.

As an improvement, 2 connecting holes are arranged on the square head, and the 2 connecting holes are respectively arranged on the upper surface, the lower surface, the left surface and the right surface and are in a cross shape.

As an improvement, each edge of the square head is provided with a chamfer angle.

As an improvement, a chamfer angle is arranged at the end, close to the square head neck, of the square head disc.

Compared with the prior art, the utility model the advantage lie in: the utility model discloses an in the embedded axle inserted core festival, welded fastening carries out again, can reduce the cracked probability of square head link, the life of extension drilling rod, simple structure, manufacturing, simple to operate.
