(54) DEVICE FOR FEEDING RODS

one.

The invention relates to a drilling technique.

A device for feeding rods is known, comprising a magazine body, guides and a feeder 1.

However, the known device provides the supply of rods only when drilling horizontal and weakly inclined wells.

A device for feeding the rods, the magazine body, is known. guides, movable carriage and feeder 2.

A disadvantage of the known device is the lack of reliability of the supply of rods when drilling wells with different angles of inclination to the horizon.

The purpose of the invention is to increase the reliability of the supply when drilling wells in any direction.

- The goal is achieved beyond C4et that the device is fitted with a rail mounted on the magazine case, turn-off cutters and croissants for fixing the rods, the rail and guides are made with steps to interact with the feeder cm, which is kinematically connected with the movable carriage.

FIG. 1 shows the proposed device, side view; in fig. 2 view A of FIG. one; in fig. 3 - view B of FIG. one; in fig. 4 - section bb of FIG. 2; in fig. 5 - the same, with barbell extended to the axis.

The bobbin feeder consists of a magazine body 1 with a bottom 2 and guides 3 in which rods 4 are placed. On the case 1 brackets 5 are fixed to hold the rods 4 when moving them inside the case or at different positions of the case 1 in space. A movable carriage 6 is installed on the guides 3 for movement in the downstream direction, which serves to feed the rods 4 to the drilling axis. On the movable carriage 6 there is an enclosed housing 1 of yoke 7 with limiting 8 fixed to it, which, like the brackets 5, serve to hold the rods 4 when moving them inside the housing 1 or with different

5 positions of the device - in space. To limiter 8 on fixed axes x

claw ts rolyky Z;

The rollers 10 and 11 are placed on the axles fixed in 6 columns 12 pivotally mounted on the carriage, spring loaded with springs 13. The rollers 9-11 ensure retention of the drill rods 4 when they are fed to the axis and. screwing in the rig.

On the bottom of the housing 1 and the lugs 14, with the possibility of rotation around the axes, there are installed cutters 15, designed to hold the package of rods in the magazine case / when moving the carriage b with the rod 4 held in the rollers 9, 10 and 11.

In the front part of the carriage 6, opposite cutters 15, there are cutouts G, which serve to accommodate cutters 15 during the passage of the rod 4 fed to the drilling axis. The length of the cutouts G corresponds in size to the diameter of the rod 4 ..

The surfaces D of the carriage b and the surface E of the trimmer 15 provide the rotation of the trimmer 15 to the position for holding the package of rods in the magazine. On the bottom of the BI casing 1 of the guides 16 s, the profile rail 17 is fastened with the possibility of longitudinal expansion, and the supports 18 of which are located in the cutouts of the W guides 16 of the housing 1. entering into contact with its movement from one of the walls of the double-acting pusher 20 located on the carriage 6.

The cutout is also less in length than the stroke of the carriage b by the diameter of the rod 4. The rail 17 with the profile surface comes into contact with the spring-loaded clamps 21 fixed on the feeder 22. The feeder 22 is a welded structure, serves to move the package of rods inside the Mairasmia case and is mounted the possibility of longitudinal translational movements on the guides 23 of the housing 1, which, like the rake 17 yyTot p | Bilo surface In contact with the profile surfaces of the 23 Hc1 guides, with spring-loaded latches 24, also secured on the feeder 22 and holding it away from return movements during the reciprocating movements of the profile rail 17. The step of cutting the profile surface on the rail 1-7 of the guides 23 to the value is equal to the diameter of the boom 4. In the eyes of the housing 1 of the driver, a hydraulic cylinder 25 is mounted, the rod connected to the eyes of the carriage, designed to move it with the thong held in the rollers.

The bobbin feeder operates as follows.,.

A device for feeding the barrel-mounted case of the magazine is attached to the frame-feed mechanism of the drilling mill.

On the feeder 22 of engagement with the profile rail 17 and the guides 23, spring-loaded clips 21 and 24 are withdrawn, the feeder 22 is retracted to the rear position. Through the space formed between the feeder 22 and the retaining brackets 5, the body of the shop 1. onto the guides 23 are placed the drill rods 4, the first of which is mounted in the rollers 9-11 of the carriage b. After that, the feeder 22 is guided to the rod package and the latches 21 and 24 are engaged with the profile surfaces of the rail 17 and the guides 23.

The drilling rod 4 is fed to the drilling axis in the following order; the piston cavity of the hydraulic cylinder 25 is supplied with oil, the carriage b associated with its rod, together with the crosspiece 7, the stops 8 and the rollers 9-11 held by the rod 4 along the guides 3 moves to the axis of drilling machine. Cutters 15 in the initial moment of movement, carriage. are in her cuts G. After the bar; is supplied to. the drilling axis of the machine, passed over the cutters 15, the carriage b with the surface D moves towards the surface E of the cutters 15, they turn around the axes and cut off the package - rods in the case 1 of the magazine.

The stop 19 of the profile rail 17 is located in the cutout G of the carriage and during its movement, the rail 17 is at rest until the pusher 20 comes into contact with the stop 19. After that, the profile rail 17. moves to the rest of the carriage 6, equal in size to the diameter of the rod 4 and the pitch of the profile, surfaces of the guides 23. Together with the rail, the feeder 22, connected to it through the spring-loaded clips 21, also moves,

In engagement with the profile surface of the rail 17. Moving,

the feeder 22 moves the boom pack all the way to the cutters 15. When the feeder 22 is moved relative to the guides 23, the latches 24 are recessed, and at the end of its stroke engages with the next cut of the profile surface of the guides 23.

 When the carriage 6 with the rod 4 is fed to the drill axis of the machine tool, the bars remaining in the case 1 of the magazine are prevented from falling out of it by the limiters 8 and holding the brackets tmi 5.

After the filing by the carriage b, held in rollers 9-11, the rod on

the drilling axis of the machine to the rod 4 moves the machine rotator and its shank is connected to the rotator chuck. Then, by moving the rotator forward while simultaneously rotating the cartridge, the rod 4 is screwed with the drill rod. During screwing, the rod 4 rotates in the rollers 9-11 and moves longitudinally relative to them by the amount of the threaded joint.

After that, the oil is fed into the rod. the cavity of the hydraulic cylinder 25, the carriage 6 is moved to its original position. At the same time, the rollers 10, statutes of Lenenie in spring-loaded racks 12, sink and release the rod 4. In the initial period of movement of the carriage 6 and the profile rail 17 remains stationary until the pusher 20 contacts the expansion rod 19 of the rail 17. After that, the rail 17 moves in a starting position on a step of the profile surface. The feeder 22 remains stationary, since its clamps 24 are located in the cut-outs of the profiled surface of the guides 23. The clamps 21 move down the slide 17, and in the initial position it engages with the next cut-out of the profiled surface. The rollers 11, in contact with the rod 4, located at the cutters 15, sink, bypass it, and in the initial position of the carriage 6 the next rod 4 is again clamped in the rollers 9, 10 and 11.

Further, the process is repeated until all the rods are dispensed from the magazine to the drilling axis of the machine.
