Abstract

The invention relates to drilling machines, is intended for drilling wells for various purposes and allows to increase the reliability of stabilization by providing a constant thrust force. The device is suspended from the lifting mechanism and includes a drill bit consisting of an electric drive 2 with a protrusion 3, a drilling tool (I) 4 and a stabilizer. The latter is fixed on a square 5, made with an emphasis 6 and a collar 7, and has levers 12 with attached blades 13. In the stabilizer glass (C) 9 by means of extension springs 10, there is a sleeve (B) 8 to which 14 is attached interacting with C 9 latch 15. The levers 12 of each of the blades 13 are attached to C 9 and B 8. On the surface of the soil there is a jig 18. When the device is immersed in the jig 18 all the way down I 4 into the soil surface, the latch 15 engages C 9, B 8 rests on a collar 7 of a square 5, C 9 rests on a support 6. Then B 8 together o C 9 descends to the lowest position until the latch 15 stops in the protrusion 3. Latch 15 rotates on axis 14 and releases B 8 from locking in C 9.

include electric drive 2, which rotates the drilling tool 4. As a result of its rotation and axial pressure, the soil is destroyed, which flows into the interior of the drilling tool 4.

As the tool is filled with 4 soil, the electric actuator 2 goes down. At the same time, square 5 remains in engagement with sleeve 8 and cup 9, which perceive the reactive moment and transfer it to brackets 11, levers 12, blades 13, jig 18 and through anchor 19 to the ground (Fig. 7).

After the drilling tool has been filled with 4 soil, the drill rim is lifted to the surface to unload the soil. When the well drilling appliance lifts up the drill string, the sleeve 8 will rise

It is attached to the lifting mechanism 1 and inclusive up to the collar 7, and the glass 9 - up to the stop 6.

A drilling tool, which consists of this, causes the latch 15 to rotate the electric drive 2 with the protrusion 3, drill the hole and fix the sleeve 8 in the cup 9 (Fig. 2).

After unloading the soil, the drilling cycle is repeated. Subsequently, as the well is deepened, the blades 13 exit the conductor 18 and are pressed against its walls.

A cable drum 16 is installed on the lifting mechanism 1 with a cable 17 connected to the electric drive 2. In order to secure (from turning) the electric drive 2 to the stabilizer entrance to the squab 17, it is pulled by means of cable drum 16 on the lifting mechanism 1 (Fig. 1).

The invention makes it possible to simplify the design and increase the reliability of a stable projectile on the rope from a single drive and spring clamp of the stabilizer blades to the walls of the well.

Claims (1)

Invention Formula A device for drilling wells, including a lifting mechanism and an electrically driven drill bit attached to 30 on the ground is installed on the ground surface due to the use of a suspension jib 18 fixed by anchors 19. The drilling device operates as follows. Initially, the device is brought to its working position (Fig. 1). Then the drilling rig is immersed in the conductor 18 until the drill tool 4 stops against the ground surface. In this case, the latch 15 is engaged with the cup 9, the sleeve 8 rests on the shoulder 7 on the square 5, Cup 9 - point blank 6. In this position, a 40 square stabilizer with levers and a rastakana 9 and bushings 8 springs 10 blades that are extremely spaced on them, differ in height, levers 12 on brackets II so that reliably spread as far as possible, the blades 13 of information stabilization due to the provision of (fig. 2-4). the constant thrust force, it is supplied glass and fixed inside the glass with Subsequently, the sleeve 8, together with the stanchion springs, the sleeve, with the tandem 9, lowers the cup and the sleeve on the squares 15B downward protrusion 3. The latch 15 is rotated with the possibility of moving On the axis 14 and releases the sleeve 8, the drive is made with a protrusion, and the sleeve - from fixing in the glass 9 (Fig. 5). In the case of a latch for fixing it relative to the result of this, the sleeve 8 under the action of a strut installed with the possibility of spreading QTIMM T OO1LIYA GGOY1 TT 1111 1-ntti Tilfnj - -1 The wiper 10 moves up and rotates the levers 12 on the brackets 11. When rotated, the levers 12 converge and press the blades 13 to the jig 18 (Fig. 6). Then fixing when interacting with the protrusion in the lowest position, while the levers of each of the blades are attached to the glass and the sleeve. include electric drive 2, which rotates the drilling tool 4. As a result of its rotation and axial pressure, the soil is destroyed, which flows into the interior of the drilling tool 4. As the tool is filled with 4 soil, the electric actuator 2 goes down. At the same time, square 5 remains in engagement with sleeve 8 and cup 9, which perceive the reactive moment and transfer it to brackets 11, levers 12, blades 13, jig 18 and through anchor 19 to the ground (Fig. 7). After the drilling tool has been filled with 4 soil, the drill rim is lifted to the surface to unload the soil. When lifting a drill bit, the sleeve 8 will rise After unloading the soil, the drilling cycle is repeated. Subsequently, as the well is deepened, the blades 13 exit the conductor 18 and are pressed against its walls. When lifting and lowering the drill string, the cable 17 is pulled by the cable drum 16 on the lifting mechanism 1 (Fig. 1).
