Abstract

A drilling installation comprises an external tube (1) provided with teeth (10) on its end-face part, an internal tube (2) and a removable sectional drilling bit (crown) (4, 5) consisting of a casing (4) and of sectors (5). The sectors (5) are provided with teeth (11) for interaction with the teeth (10) of the external tube (1). The teeth (11) are oriented along a circumference in relation to the axis of the drilling installation and are made of a material whose hardness is lower than that of the material of the teeth (10). The external surface (3) of the internal tube (2) is provided with radial protrusions (16) mounted between the sectors (5) with the possibility of contacting by their lateral surface (17) with the lateral surface (18) of the sectors (5) of the removable bit (crown) (4, 5).

FIRST TIME SURROUNDING TECHNIQUE The invention is available in a large variety of equipment, but is it more convenient in terms of drilling ?.] for drilling. The most successful, more comprehensive invention may be used in the general business for drilling with a loss of peace or loss of confidence.

The preceding equipment level is 10 Β of bullets, as there is a live solution, drilling is carried out when the appliance is turned off. In this case, the reliability of the work of a light bullet depends on the reliability of the transmission of a short-circuit to the disruptive tool of the outdoor-rocket. This reliability in various operations is ensured by various ways.

A drill has been known to contain an external pipe, an internal pipe and a detachable cat shell (ϋ5 _§ d ^ 3692126). On the outside of the outdoor pipe, an internal 20-side discharge was made.

In order to be able to use the outside of the building, there are radial storages located between the interconnections with the intercom.

In the process of operating rocket launchers, the teeth of the outer pipe wear out, as a result of which they are less likely to penetrate into the teeth of the removable core: - 4 - to the slipping of the teeth of the outer pipe of the other teeth of the cultivator, especially to the occurrence of strong accidents of the city. Otherwise, slipping? It may be 5 months at the beginning of drilling and not yet completely penetrating the teeth of the external pipe into the teeth of the cutting section. The presence of the indicated differences in the height of the outside of the outside pipe excludes the possibility of slipping and, in so doing, increases the reliability of the load. 10 Quick Descriptions of Drawings

In the outdoor part of sections 5, heights 6 were made (Fig. 2, 3), and in the lower part of the outer pipe I, 5 parts 7 were made for it to be open for 6 months.

In the internal circuit of sections 5, the devices 8 were made for fixing on the internal pipe 2 in the working shell of the shell.

10 of the external part of the external pipe I on the internal external part 9 (Fig.), The complete teeth 10 (Fig. 2), located in the entire dry season, were made. Sections 5 of the removable core 4,5 have teeth II for interaction with teeth 10 of the outer pipe I. Prongs of the II section 5 are rotated πο

15 OUTPUT OF A RELATED PRODUCT FOR SUSARADIANS (SHIG.6) AND EXECUTED FROM THE MATERIAL

The inner pipe 2 is in the hard part connected to the suspension 12, equipped with gears 13 and under the crankshaft

20 14. Stations 13 are located in recess 15, made in the external pipe I, and are intended for the prevention of the movement of the pipe 2 to the occupancy of the room. On the other hand, steps 13, clinging to the inside of I and the outside of 2 pipes of a friend with another, are used for

25 times out of the way of the outside ^' pipe I to the inside pipe 2.

Β of the lower part of the inner pipe 2 on its external part 3 there were performed radial steps 16 (Fig. 8,9), which are placed between sections 5 for 4.5 times

30 with the interaction of its lateral parting with 17 with lateral parting with 18 sections 5 of section 4.5. Steps 16 are intended for the transmission of short-circuiting torque to a quick-contact 4.5 part of a rotating internal pipe 2 if there is a loose tooth in case of wear

35 tooth teeth II sector vane 4.5. Otherwise, there is a loss of speed of 16 on the inside of the pipe 2 of the second section 4.5 at the beginning of drilling of the second half of the second tooth of the second half of the tooth

The part of the 5th section of the housing 4.5 has the property of being large, due to the fact that, due to the location of the pipe 2, the inside of the room is 4.5%, the room is in the process.

Β of the lower part of the inner pipe 2 is mounted on the outer ring 21. Sections 5 of the 4.5 section are equipped with 22 external components, such as diamonds, for example, 20

Drilling equipment works as follows. OUTSIDE THE OUTDOOR TUBE I DROPS OUT TO THE BOTTOM INDOOR TUBE 2 WITH A SECTOR BOX 4.5. With this, the inner pipe 2 is located in other units 20 of the room 4 of the section 25 25 and the small unit 4.5 is moved down with it. In the lower part of section 5, thanks to its installation, it is unfastened, units 6 are installed in section 7 of outdoor pipe I and the network is 4.5. The inner pipe 2 is at the same time moving down 30 inside the compartment 4,5, pushing apart the other 20 units 4 and sections 5 4,5. The movement of the internal pipe 2 is limited to 8 sections 5, and at the same time it is slowed down and prevents its movement.
