The purpose of the invention is to monitor these specified aerotomatics. The basis of the backbone of the field is a co-ordinate unit for the burev oxBaxj H of a painful two-meter, in which the center of gravity of the ba-drvblvzhev in aaboia is at the top of the harness of the axes of axle axles. . . , BJra aadacha is teeted that the cargoes — ut — the descalers, which are interposed between: the military and the secondary bushings, are located between the turbo-drums in.,. “The ouiMBttOB Bh bursts are formed on their horses.

The drawing shows the proposed unit, a longitudinal section.

. ; The unit consists of several turbo drills I connected

0 traversing 2 flanges 3. Turbo-drills I are attached to the traverse at the end of the threaded connections. The hull 4 of the turbodrills in the lower part of the Nuenr annular protrusion 3, on which, through the insertion of 6, lends ita 7, the lectKO is called the lower part of the turbodrills I and the case carries loads of the utmost 8. The latter are made of litikv. The arrangement of loads 8 in the lower part of the unit along the length of the turbo-drills I ensures that the center of gravity of the aggregate is approached to the bottom, which can withstand the verticality of the well. At the top of the turbo drills

11i1ametsvSh1 spacer sleeves 9, which made all sistenu monolithic.

 . The aabo breakthrough is drilled on the paths of the drilling turn of the drill and the turbo drills for a long time. Snatch it around a vertical wasp.

The precursor of the invention

An aggregate for drilling wells of large diameter and mine shafts, ooookhchy such as turbo-drills, characterized by the fact that

bringing the center of gravity of the unit to the zabov and relieving the upper threaded connections of the turbo drills from axial loads, the loads - ut zhelitag, between them are separated by screw bushings, are located mehda i turbo drums opmroto on the shoulder, formed in their hulls .;
