Description

FIG. 1 shows the executive organ in plan; pas figs. 2 - the same with the cut-off cutting augers; on fng. 3 shows the node I in FIG. one; in fig. 4 - node II and FIG. 2; FIG. 5 - section aa aa fng. four.

The executive body of the crown drilling machine includes parallelly disposed worm drilling rigs 1, 2 and 3 with supporting lights 4 and 5, a central head pin 6, equipped with a threaded coupling 7, an interaction, with a thread 8 on the shank 9 of the central drilling rigs 2, deviating cutting screws 10 with tons of gamna 11. The device for turning the deviating screws 10 is made in the form of squarely located cheeks 12 with a Z-shaped slot 13, nails 14, rigidly mounted on the hooks And located in Z-shaped slots x 13, spring-loaded latches 15 with The position of the 16, movably stopped on the cheeks 12, the ring 17, the shank and the shank 9 of the central drilling rod 2 n made with a bevel 18, interacting with the protrusions 16 of the clamps 15, the cylindrical casing 19, installed on the muff 7 with the possibility of rotation and lifting the hole 20 in which fixer 15 is placed. Herewith, the coupling 7 is made with grooves 21 for engagement with a clamp of the clips 15. The casing 19 is connected to the coupling 7 by means of a reverse coupling 22. The shank 9 is provided with a cutter 23, which is interchangeable with a travel stop 24, reinforced in the clutch.

The organ works as follows.

After zaburpvann at a predetermined depth, the executive body recovers pz production at Velnchin / (Fig. 1), becoming 2 is reversed in a rotational movement, and through clutch 22, the casing 19 interacts with the clutch 7, which swings from the shank 9 together with the screw 6 n moves toward the slaughter. The bevel 18 comes out of contact with the protrusions 16 and the latches 15 rigidly connect the casing 19 to the coupling 7 by inserting their ends into the slots 21. Inside the surface of the paclon sections of the slots 13 moving t g and act on the fingers 14, moving them along with t gad-g 11 g. The rotational cutting pitch is 10 degrees and the angle a.

After termination of the interaction of the threads of the coupling 7 and the shank 9, the central drill stand 2 is fed from the bottom to the contact of the stop 23 with the stop 24, as a result of which the fingers 14 enter the lower longitudinal sections of the slots 13 (Fig. 2 and 4), which

eliminates the reduction of rejected 10n reloading augers unloads the central drill rig 2 from the restraint. In this nozhelechnn n-polnppley body is nzleklyayut nz working with the rotation of all the staves. Rejected cutting bows 10 undercut the naked bone, which is transported to the wellhead. For 10 in 1 reduced augers

for drilling (FNG. 1), becoming 2 reverses and nods in the side to the bottom until the threads of the 1 thread of the 7-n-sleeve coupling 9. As a result, the auger 6 with the 7-n-pin coupling 12 advances to become 2, the naltsy

14 exits from the longitudinal sections of the nroresis 13 and, up to the external surfaces of the inclined sections of the ethnical slits, move to the coupling 7 together with 11 n deviating bolts 10.

After the termination of thread inserts, the threads 14 will enter the upper longitudinal sections 13 (phi I n 3) and fill the upper organ to the examining drill.
