Abstract

The invention relates to the mining industry and allows to increase drilling productivity by reducing the time for auxiliary operations and to increase the reliability of the machine. It includes a mechanism for clamping the rod 6, in the body 11 of which cams 17 are placed, and a kinematically connected shank (X) 18 with the body 11, the end of which is threaded for connection with the rod. The kinematic connection is made in the form of a cup 21 coaxially fixed at the end of X 18 with protrusions 22 and nozzle 14 with corresponding labyrinth grooves 23. The nozzle 14 is rigidly connected to the housing 11. The outer diameter X 18 is equal to the outer diameter of the rod. Having drilled the length of the first boom, the drill machine shuts off. The bar is clamped by the cams of the machine holder. Cams 17 open. The torque is transmitted by X 18 through the projections 22. Moreover, the X 18 is unscrewed from the rod and retreats to its original position. The next boom is increased and screwed to the previous bar. The cams 17 and the pins of the holder are clamped and unclamped. Drilling continue to a predetermined depth. Next, the launch operations are performed. The process is repeated. 4 il. (cl

The invention relates to the mining industry, in particular to drilling rigs i by the mechanized operation of lowering - lifting the drill rods. j The purpose of the invention is to increase the productivity of drilling due to cutting, saving time for auxiliary operations and increasing reliability.

FIG. 1 shows a drilling rig while drilling; in fig. 2 - the same, at the time of the launching operations; in fig. 3 - vrash, atelier of the drill: a machine with a shank and a rod; in fig. 4 - I section A-A in FIG. 3

i The drilling machine contains a control panel I of I, frame 2 with base 3, feeder 4, 5 i drill rods 5 and 6, rod holder 7, I rotator 8 including housing 9, rod clamping mechanism consisting of a gear wheel 10 the cylinder with the housing 11, the sleeve 12 connected by

Having drilled the length of the first boom, the feeder 4, the rotator 8 and the drilling machine are turned off. The rod 5 is clamped by the cams of the rod holder 7, the cams 17 of the vragger 8 are simultaneously unfolded, reversed to the rotator 8 and the feeder 4. The torque from the gear 10 with the housing 11 and the pipe 14 is transmitted to the shank 18 through reversing rotation meshing with the labyrinth grooves of the nozzle 14. The shank 18, rotating, is unscrewed from the rod 5 and, together with the rotator 8, moves to the initial position. The next bar 6 is increased and screwed with the previous bar 5. The cams 17 of the rotator 8 are clamped and the cams of the rod holder 7 are simultaneously unclamped, the rotator 8 is turned on, the feeder 4 and the drill machine. Drilling continues to preset

belt thread with a hub 13 toothed .20 depth, wheel 10, nozzle 14, rigidly attached-When a predetermined depth of the deformed to the body 11 has been reached, the clamp-clamp mechanism or, if necessary, the replacement of the zastuga, the piston 15 placed in the tooth-beer bit cavity is produced Spraying wheel 10, rod 16 piston 15, all operations. The shank 18 is screwed

located between the sleeve 12 and the housing 25 of the rod 6, the protrusions 22 of the cup 21 by the removal of 11, the cams 17 placed in the radial of the labyrinth grooves 23 of the socket slots of the sleeve 12, and the shank 18 with the gland 19 and the thread 20 for connection with drill rods installed in the sleeve 12 of the mechanism for clamping the rod.

The rod 6 is passed through the sleeve 12 and clamped by the cams 17 of the rotator 8, the feeder 4 is reversed and the rod is removed from the well, while the rod 5 passes through the holder 7. Then the cams of the holder 7 are clamped and the rotator 8 is transferred by the transmitter 4 to its original position as shown

there is a kinematic connection shank

18 with housing 11 of the mechanism for clamping the rod. The drilling rig works as follows

in a way.

The remote control 1 and frame 2 with base 3 are installed in the bottom hole. A frame 4 with a bar holder 7 and a rotator 8 is mounted on the frame 2 and adjusts to the well. Shank 18 with oil seal

19 and a thread 20 for connection with the drill 5 rods is installed in the sleeve 12 of the rod clamping mechanism, wherein the protrusions

The rod 5 is screwed onto the threads 20 of the shank 18, 50 the cams 17 of the rotator 8 are clamped and simultaneously the cams (not shown) of the holder 7 are depressed. The rotator 8 is turned on, the feeder 4 , a drilling machine (not shown), which approaches the bottom, and begins drilling.
