Description
Technical Field
The utility model relates to a dig drilling rod technical field soon, specifically indicate a dig drilling rod soon and use mouth guard ring.
Background
The rotary drilling rig is a construction machine suitable for hole forming operation in building foundation engineering. The rotary drilling rod is an important component of the rotary drilling rig, the rotary drilling rig generally comprises a plurality of sections of sleeves which are embedded together, the drill rod with the largest radius is a first section of drill rod, the drill rod with the second largest radius is a second section of drill rod, and the like. When the rotary drilling rod is used, the inner tooth section needs to bear pressure and torsion frequently, so that the rotary drilling rod is easy to crack and is damaged.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, a dig the drilling rod soon and use the mouth guard ring is provided.
In order to solve the technical problem, the utility model provides a technical scheme is a dig drilling rod soon and use mouth guard ring: comprises a circular ring plate, a tooth block arranged on the inner side of the circular ring plate and a key bar block arranged on the outer side of the circular ring plate; the inner diameter of the circular ring plate is the same as that of the section rod, and the outer diameter of the circular ring plate is the same as that of the section rod; the number of the tooth blocks is 3, the 3 tooth blocks are uniformly arranged along the circumference of the circular ring plate, and the cross section profile of each tooth block is the same as that of an inner tooth strip of the inner tooth section of the joint rod; the number of the key strip blocks is 3, the 3 key strip blocks are uniformly arranged along the circumference of the circular ring plate, and the cross section profile of each key strip block is the same as that of the end, close to the inner tooth section, of the outer key strip of the section rod; the circular ring plate, the tooth blocks and the key strip blocks are integrally formed.
Compared with the prior art, the utility model the advantage lie in: the utility model discloses can strengthen the orificial intensity of tooth section in the festival pole, the probability of tooth section fracture in the reduction, the life of drilling rod is dug soon in the extension.

Detailed Description
The following description is made in detail with reference to the accompanying drawings for a mouth guard ring for a rotary drilling rod of the present invention.
With reference to the attached drawings 1-4, the mouth protecting ring for the rotary drilling rod comprises a circular ring plate 1, a tooth block 2 arranged on the inner side of the circular ring plate 1 and a key bar block 3 arranged on the outer side of the circular ring plate 1; the inner diameter of the circular ring plate 1 is the same as that of the joint rod, and the outer diameter of the circular ring plate 1 is the same as that of the joint rod; the number of the tooth blocks 2 is 3, the 3 tooth blocks 2 are uniformly arranged along the circumference of the circular ring plate 1, and the cross section profile of each tooth block 2 is the same as that of an inner tooth strip of an inner tooth section of the joint rod; the number of the key bar blocks 3 is 3, the 3 key bar blocks 3 are uniformly arranged along the circumference of the circular ring plate 1, and the cross section profile of each key bar block 3 is the same as that of the outer key bar of the section bar close to the end of the inner tooth section; the circular ring plate 1, the tooth block 2 and the key strip block 3 are integrally formed.
The utility model discloses when concrete implementation, the ring board 1 that will protect the choma aligns, tooth piece 2 aligns with interior tooth strip, key strip piece 3 aligns with outer key strip with the interior tooth section mouth of pipe of festival pole, then welded fastening, the polishing of slagging-off. The mouth protecting rings can be arranged on other sections except the tail section, so that the reinforced protection of the pipe mouth of the inner tooth section of the whole rotary drilling rod is realized.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
