Description

The invention relates to mining di., In particular to well drilling equipment. A device for moving pipes is known, which contains a rotary beam with a movable elevator, a movable gripper and a stand with constraints on the movement of the pipe and elevator 1. However, this device does not align the axis of the lowered elevator with the axis of the vertically mounted pipe, and therefore allows the elevator end to stop. in the upper end of the pipe, eliminates the timely capture of the pipe by the elevator and, consequently, the automation of work on the descent-lifting of the pipe string. A device for moving pipes of an automated drilling rig is known, which contains a turntable with a guide attachment, including turning doors and a pipe movement restrictor pivotally connected with the guide attachment 2. The disadvantages of this device are considerable time spent on handling. with a pipe, if it is necessary to lift the pipe after it is grabbed by an elevator to a height exceeding its length (before it leaves the guide), to divert the guideline lazy with the zone and then lowering pipe elevator for subsequent buildup with its column. The purpose of the invention is to improve the performance of the device by reducing the time taken to remove the pipe from the guide. The goal is achieved by the fact that a device for moving pipes of an automated drilling rig, comprising a turning beam with a guide device, including rotary shutters and a pipe movement limiter, hingedly connected to the guide device, is provided with a knurling unit mounted fixedly on the axis the pivoting beam, and the pipe travel stop is spring-loaded relative to the guide device and is provided with a cable covering the bypass blocks rigidly mounted on the pivoting Alkeya, wherein one cable end is coupled with the stopper moving pipe and the other - with the follower block. FIG. 1 shows the proposed device, general view; in fig. 2 — node 1 in FIG. 1 guiding device in the initial position after closing the flaps); in fig. 3 shows section A-A in FIG. 2; in fig. 4 is a section BB in FIG. one; in fig. 5 is a view of B in FIG. four; in fig. 6 — device with a descending elevator; in fig. 7 — guiding device with a descending elevator; in fig. 8 - elevator after descending against the stop in the guide device. The device is mounted on platform 1, mounted on rails 2, and includes Support Stands 3 and 4, a hydraulic cylinder 5 turning the turntable 6 with grippers 7 d; 1 holding the drill pipe 8 and the housing 9 of the direction of attachment connected to the beam 6 and fitted with Elevator movement limiter 10 and pipe 8 movement limiter 11. AjapHiipHo folding flaps 12 (Fig. 2) and 1 hydraulic actuators 13 of the flaps 2 are mounted ajapHiipHo, pipe movement limiter 11 is movable in window 14, which is made from the housing 9 and the return springs 15 associated with it. The housing 9 and the flaps 12 are combined locally, on the one hand, with a cone nozzle 16 and a centering ring 17, and on the other hand, segments 18 (Fig. 3) on the leaflets 12 and a semi-ring 19 on the housing 9. The segments and the semi-ring 19 form centralizer for pipe 8. On the pivot beam 6 (Fig. 4), the bypass blocks 20 are mounted. And on the fixed axis of rotation 21 of the pivoting beam 6, a rip block 23 is mounted on the pin 22. The limiter 11 of displacement of the pipe 8 is connected by a cable 24 - 6) through the bypass blocks 20 with a copier block 23 (FIG. 0), the cable 24 being laid in a special groove 25 and fixed on the axis 26. These elements make up the drive of the rotation of the dipole 11. Elevator 27 (Fig. 7) and has in the lower part of the shed 28 with the input chamfer 29 under the pipe 8 and is equipped with gripping jaws 30. The device operates as follows. In the initial position, the pivot beam 6 is in a horizontal position, the claws 7 are open, the shutters 12 are open, the stop 11 of the displacement of the pipe 8 is held by springs 15 inside the body 9. The pipe 8 is placed in the clamps / and the semi-ring 19 of the body 9 of the guide. Then, the clamps 7 are closed, with which the pipe 8 moves up to the stop to the stop 11, then pressure is applied to the hydraulic cylinders 13 and the flaps 12 are closed. When closing the valves 12, their segments 18 and the half ring 19 of the housing 9 combine the tube 8 relative to the cylindrical ring 17. After that, the swivel beam 6 is turned with the hydraulic cylinders 5 aligned with the tube 8 by 90 ° to a vertical position (Fig. 6). When the beam 6 is rotated into a vertical position, one end of the cable 24 is wound on the copier unit 23, and the other end of the cable removes the stop 11 from the housing 9. At the end of the rotation of the beam 6 into the vertical position, the stop 11 completely leaves the housing 9. After the beam 6 is installed in the vertical The position of the elevator 27 is lowered and, when the wind is winding with a conical nozzle 16, the axis of the elevator 27 and the ring 17 are centered even with a significant mutual displacement of their axes. Since when the shutters 12 are closed, the centering of the tube 8 relative to the ring 17 is performed, when the elevator 27 is run down, the throat of the elevator reliably points to the upper end of the tube 8. The ring 17 is made with a diameter slightly larger than the diameter of the elevator 27 and has a small height 9 and the shutters 12 are larger than the diameter of the ring 17, which allows free passage of the elevator 27 without sticking to stopping it on the stop 10 without rubbing against the housing 9 and the shutter 12. After stopping the elevator 27 on the stop 10 of the housing 9, the elevator 27 closes a pipe 8, then open the flap 12 and removed from the guide prisposoblemne elevator motion zone 27, then elevator 27 is lowered with a pipe 8 for connecting the pipe 8 to the column (not shown). In the initial position of the device (in the horizontal position of the beam 6), moisture is removed through the window 14 of the housing 9 located below, therefore moisture does not accumulate in the housing 9 and ice does not form, and this eliminates jamming of the elevator 27 when operating in any climatic conditions. Thus, the alignment of the elevator with the pipe is provided at large mutual misalignment values, arising in the case of wind, dynamic, as well as loads arising during subsidence of the foundations of the drilling rig. In addition, there are no cycle disturbances due to the avoidance of ice formation in the guide device. Ensuring the centering of the pipe relative to the guide fixture significantly increases the reliability of pointing the shed of an euvator to the end of the pipe, especially in the presence of the curvature of the latter. Improving the performance of the device is provided by reducing the time taken to remove the pipe from the nanowire.
