Abstract

The invention relates to mining and can be used in the construction of rising and horizontal wells from underground mine workings. The purpose of the invention is to improve the performance of the device. The device comprises a frame 1 with a support assembly 2 and guides 5, a rotator 3, an L-shaped bracket 16c fixed by a feeder 10 fixed to its cantilever projection 10 with a grip 17 and racks with a receiving bridge 12, an emphasis 21, a double-arm lever 13 and rods 9. When extending from the feeder 10 of the grip 17, the latter grips the bar 9 and at the same time comes into contact with one of the ends of the two shoulders lever 13, lowering it down.

The invention relates to mining and can be used in the construction of rising and horizontal wells from underground mine workings.

The purpose of the invention is to increase productivity.

FIG. 1 shows a device for drilling wells, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. one ; in fig. 4 is a view of B in FIG. 2; in fig. 5 - the same, at the moment of approaching the grip; in fig. 6 - the device at the time of transfer of the rod from the rack to the rotator; in fig. 7 - the same, after combining the rod with the axis of the rotator.

The device for drilling wells comprises a frame 1 with a support unit 2 and a rotator 3 mounted thereon with sliding elements 4 along the guides 5, a feed mechanism 6 made in the form of a power cylinder connected to the rotator 3 and frame 1, the holder 7 of the drill rod 8, rods 9, feeder 10 rods 9 and a rack 11 with a receiving bridge 12. The rack 11 is equipped with a double arm 13 that is pivotally mounted and installed under the bridge 12 with a drive lever 14. The feeder 10 is mounted on a cantilever ledge 15 fixed on one of the 5G-rails figuratively The bracket 16 is provided with a spring-loaded gripper 17. The feeder 10 is made telescopic, has support 18 for the hydraulic cylinder 19 and hydraulic cylinder 20 for extending the gripper 17. The bracket 16 is located in height between the rotator 3 and the holder 7 of the drill rod 9 8. The receiving bridge 12 has an adjustable in two positions (when lowering the projectile above the surface of the bridge 12, and when lifting - below it) stop 21. The double-arm lever 13 has the ability to rotate around the axis 22 relative to the working surface 23 of the receiving bridge 12. By one side the lever 13 through the spring 24 is connected to the platform 25 of the trolley 26 of the rack 11, and the other, through the drive lever 14, contacts the gripper 17 of the feeder 10. The lever 13 is provided with a pressure plate 27, through which the rod is located directly in front of the stop 21.

The rack 11 has a shelf 28 that can be moved along the rails 29. The platform 25 is provided with a swiveling hydraulic cylinder 39 relative to the trolley 26. For

for separating rows of rods 9 placed on shelf 28, inter-row gaskets 31 are used. The rack 11 is also provided with a hydraulic cylinder 32 for lifting the shelf 28 to the required height and a pump 33 for

control cylinders 30 and 32.

The device works as follows.

After installation and fixing of the device in the drilling chamber by a hydraulic cylinder 30

from the pump 34, the platform 25 is lifted together with the shelf 28 with the rows of rods 9 placed on it and the rack 11 is rotated to the required angle, ensuring a position at which the working surface 23

the receiving bridge 12 and the upper inter-bottom of the gasket 31 are placed in the same plane, with the rods 9 rolling down until they come into contact with the stop 21 (the first rod). The first one is laid directly on

receiving bridge 12 up to the stop 35. Hydraulic cylinders 19 and 20 of the feeder 10 are turned on from the control unit pool and the gripper 17 is brought to the rod 9. With the further movement of the gripper 17 to

fully fixing the rod 9 in it at the same time gripping 17 with its working edge 36 acts on the drive lever 14, through which the two-armed lever 13 is rotated about the axis 22, while

By means of the pressure pad 27, the lever 13 acts on the rod 9 positioned in front of the stop 21, its compartment from the common row of rods placed on the shelf 28 and raised above the stop 21. Subsequently, when the clamp 17 is withdrawn together with the gripped belt 9, the trimmed bar under its own weight rolls off on an inclined plane on the working surface 23 of the receiving bridge 12 up to the stop 35, occupying the initial position

to grip, and the spring 24 returns the two shoulders lever 13 to its original position. The hydraulic cylinder 19 moves the gripper 17 with the gripped rod to an intermediate position. Then hydraulic cylinder 20 horizontal

The rod 9 is brought to the axis of rotation between the rotator 3 and the holder 7. The rotation of the spindle of the rotator 3 is turned on, and the feeder 6 is supplied to the rotator to the rod 9. Since the gripper 17 is made spring-loaded, it is possible to screw the spindle of the rotator 3 with the rod 9, after whereby the gripper 17 releases the barbell and is withdrawn from the working area to an intermediate position. The spindle of the rotator with the rod is connected with the position of the 8 rods, the holder 7 releases the becoming of the rods and starts drilling. In order to build up the next boom, the pump 10 is gripped by the method described above, and the cycle is repeated. After using all the rods of the first row, the inter-row gaskets 31 are removed, the hydraulic cylinder 32 lifts the flange 28 along the guides 29 of the platform 25 until the upper level is aligned with the next one. inter-row gasket 31 to the level of the working surface 23 of the receiving bridge 12.

In order to lift the projectile (disassemble the drill rod), the hydraulic cylinder 30 lowers the shelf 28 to the required angle, allowing the weight of the rod 23 from the receiving surface 23 of the receiving bridge 12 to slide down onto the shelf 28, while the stop 21 is led under the working surface 23 of the bridge 12. After holding the 8 rods on the holder 7 and the collar 9 of the rods from the 8 rods and moving the threads of the spindle of the rotator 3 operations are performed in the reverse order. For this, the rods are gripped on the drilling axis by the gripper 17 of the feeder 10 and the hydraulic cylinders 19 and 20 are moved until the rod 9 touches the working surface 23 of the receiving bridge 12 of the racking 11, after which the gripper 17 releases the bar which rolls along the inter-row spacers 31 to the shelf 28.

The cycle is repeated until the rods are completely removed from the well.
