Description

Aamk for C1) are known sdtsnen of the most common drill rods, which have at the end, the Nyangnplplig: K; viiiT nputrs іiis, gg.chpchs bar: i meg, t (p; ii 11 L () - / 1; (; n1111 iamkd.

For s ó ódiodeki T | 1 оч оч оч 11 11 11 11 11 ны ны, we are rods, leering torque of both signs, known locks are not irnable, and the narrow sections of the bridge in the place of the castle are inherent in locks of the castle; and cement mortars, irnmenymi, and chastotnos, used 1 1 auger drill rods for s.oozhents lined with cement brown wells.

The lock, according to Iben), has the peculiarity that, from an irregularity of torque, 1) more than 11 bu)) il itang in both directions and u-countryin narrowing of the internal cross section, they have a lock joint at the end of one I1tang11 On the inside there is a nickle1) a joint with internal Ilitsa or a polyhedron, inside of which the correspondingly processed end of the other, adjacent Iiangi, connection 1i1, it comes in, with iKJpBou freely rotating nut, which receives axial forces, and transmitted to it by rods

On fi1. 1 shows, in part, a section, of an Ischekova drill pipe with a lock; in fig. 2 shows a section I0 (AL) and (III)) in FIG. one; in fig. ;. castle nakazan assembled; in FIG. J-7-seyppk; of the castle in D1) angle 11 iliii i4i his winnings.

On pd1I1M there is a tubular uyiui.iniioii Іtangi (1) synecppm (2) and an ichi hIhI-pepelene (irishchna) coupling (}) (internal n: 1its (4), which has an unnii. Internal screw thread (5).

The other end of the rod (1) is provided with outer splines (G), the number of which and the shape correspond to the splines (o). The transition of the section of the rod with the splines (G) to the neighboring section is made by the irregular mouth, designed to interact with the end of the connecting nut (7) of the lock, swivel on the yoke and provide a hex key with iodine key. The butt of nggagi with eagles (6) has a cone (8) corresponding to the cone (9) of the end of the adjacent 1th string.

For the connection of two Iggy konea, s-slots (G) of one Inangn, the inner, couplings (3) of the end of the other rod to the Uior of the cone (8) are inserted into the cone (9) (Fig.; I). Then tighten the connection with a nut (7). screw cutting which vzpmo.deliyeT with screw thread (5) coupling (H). The axial forces transmitted along the rods are perceived by the nut (3), and the torque of any sign is perceived by the walls ;; 1 (4) and (6).
