The rotary drilling rod is a piling construction drilling tool, construction conditions are poor, the rotary drilling rig needs to swing left and right in the construction process, the stress of the drilling rod is too large, cracking and abrasion phenomena frequently occur at the bottom of the perforated pipe of the drilling rod, a wear-resistant sleeve is determined to be added according to the two quality problems, the integral rigidity of the perforated pipe is improved, the hardness of the material is technically improved, and the problems of abrasion and cracking at the bottom of the perforated pipe are thoroughly solved.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: the abrasion and cracking phenomena at the bottom of the drill pipe perforated pipe are solved.
The technical problem solved by the invention is realized by adopting the following technical scheme: the utility model provides a drilling rod floral tube with floral tube wear-resisting cover which characterized in that: the drill pipe comprises a drill pipe perforated pipe body and a perforated pipe wear-resistant sleeve, wherein the perforated pipe wear-resistant sleeve is welded and fixed at the bottom of the drill pipe perforated pipe body.
Furthermore, the drill rod perforated pipe body comprises a steel pipe, a plurality of key bars and a plurality of inner key plates, the inner key plates are uniformly distributed on the inner side of the steel pipe, the key bars are arranged on the outer side of the steel pipe, and the inner key plates are arranged on the opposite sides between the two key bars at intervals.
Further, the shape of the perforated pipe wear-resisting sleeve is matched with the shape of the bottom of the drill pipe perforated pipe body.
Further, the floral tube wear-resistant sleeve comprises a plurality of concave parts and a plurality of convex parts, and the concave parts and the convex parts are arranged at intervals and are integrally formed.
Furthermore, the concave part and the convex part are made of NM550 high-strength steel, and the hardness reaches more than 400 HRC.
The invention has the beneficial effects that:
the drill rod tube-flower device is simple in structure, improves the integral rigidity of the drill rod tube-flower, thoroughly solves the problems of abrasion and cracking of the bottom of the tube-flower when the drill rod works, reduces the cost and improves the working efficiency of the drill rod.
