Description

The invention relates to the mining industry, in particular to devices for increasing and dismantling drill rods when drilling rebel wells using drilling lights in drill rigs.

A device for supplying drill rods, consisting of a stationary body, a carriage and a hydraulic cylinder [1].

However, this device is designed to build smooth rods, it does not provide the supply of lantern rods and dismantling of the drill rod.

Closest to the present invention is a device for feeding rods, comprising a stationary housing with guides, a movable carriage, on which axle-mounted spring-loaded levers with rotating rollers and limiters of their rotation, and spring-loaded latches to limit the longitudinal movements of the rods [2].

A disadvantage of the known device is that it does not provide the supply of rods with support lamps, sufficient reliability and safety of work, remote control of the extension and disassembly of rods.

The purpose of the invention is the provision of the possibility of building and dismantling the rods with supporting lights when drilling rebel wells and improving the reliability and safety of work.

5 This goal is achieved by the fact that the movable carriage is made U-shaped, at the end of which is placed the rod of the rod lights, and the carriage guides are mounted on the upper surface of the housing, while the spring-loaded fix. The snoods have stoppers to keep them in a non-working position.

FIG. 1 shows a device with a rod moved to the axis of drilling, bottom view; in fig. 2 - section A — A in FIG. one;

15 in FIG. 3 is a view B in FIG. one.

An apparatus for feeding rod consists of a stationary body 1 with fixed on it by longitudinal guide legs 2, 3 and the movable carriage _20, the hydraulic cylinder 4, which ^{kinematically} connects the housing 1 and the carriage 3 via lugs 5 and 6 axis.

The carriage has a U-shaped design, consists of sidewalls 7 and 8 and parallels 9. Sidewall 7 carriage is installed in direction 916741

2. The sides 7 and 8 have the same arc-shaped notches 10 with a radius equal to the radius of the drill rod, and the distance b between parallels 9 is equal to the diameter of the rod. The arcs of the cuts 10 are the pushers of the rod 11. On the sidewall 7, the pusher 12 of the flashlight 13 is rigidly fixed.

On the front ends of the parallels 9 of the carriage 3 on the axes 14 with one ends, the corner levers 15 are installed in pairs with the possibility of rotation, the other ends are also pairwise interconnected by springs 16. The springs 16 are placed on the couplings 17, which are mounted movably in the axes 18. On the 15 axes arranged in the levers 19 rollers 20 are freely mounted. The angles of rotation of the levers 15 are limited by the stops 21 fixed on the carriage.

The housing 1 is equipped with four pairs of guides 22, inside which the same clamps 24-27 are mounted, which are compressed by springs 23 and have bevels 28. Longitudinal movements of the clamps in the guides 22 are limited by slats 29. Guides 22 are provided with stoppers 30 (for example, screw-type) that fix the non-working position of the locks 24-27 through the sockets 31 on the last.

The tabs 24 and 25, as well as 26 and 27 are installed in such a way that their bevels 28 are directed respectively to the rear and front ends of the carriage.

The device for feeding rods works as follows.

The carriage 3 is displaced to the rearmost position, the latches 24 and 26 are unlocked, the latches 25 and 27 by the stoppers 30 are locked in the guides 22 and removed from work (Fig. 1 and 3).

In the U-shaped groove of the carriage 3 are installed two rods with support lamps 13 on the side 7 (Fig. 2). In this case, one rod is placed between the rollers 20 and is held in them by the springs 16 through the levers 15. The reciprocal displacements of the rods in the feeder are limited to the supporting surfaces of the lanterns 13, the rollers 20, the arcs of the notches 10 with the pusher 12 and the guides 9.

Moving the carriage 3 to the extreme front position, the boom lights are fed to the drilling axis of the machine. The second rod arcs 10 and the pusher 12 of the carriage moves forward simultaneously with the first and at the same distance in length. When moving forward, the second boom with a lantern hits the bevels 28 of the clips 24 and 26 and sinks them. At the end of the carriage advance and the passage of the rod lights, the latches 24 and 26 are returned to their original position by the action of the spring 23 and hold the second lantern rod from moving backwards when the carriage returns to its extreme rear position. At the end of the stroke backward, the carriage 3 with rollers 20 captures the second rod 11. The next movement of the carriage forward leads the second rod onto the drilling axis. Then the feeder carriage is retracted and loaded again with lantern bars.

In the process of connecting the rods with the drill rod and the drive chuck of the machine, the carriage 3 reliably holds the lantern rods on the drilling axis through spring-loaded levers 15 and rollers 20, ensuring their movement along the drilling axis.

When dismantling the rod device operates as follows.

The tabs 25 and 27 are uncoupled, and the latches 24 and 26 by the stoppers 30 through the slots 31 are removed from work. The device is not loaded with lantern bars.

The feed of the carriage 3 to the extreme front position of the rollers 20 on the axis of the drilling captures and holds the lantern rod to be removed. After disconnecting from the drill rod and the drive chuck of the machine, the lamp rod, when the carriage 3 moves backward, inserts the latches 25 and 27. At the end of the carriage’s backward motion, the latches 25 and 27 return to their original position. To extract the second lantern rod from the drilling machine, the carriage 3 moves to the forward position, the latches 25 and 27 hold the rod in the feeder, freeing it from being held by the rollers 20 and the springs 16.

The second lantern rod is removed from the drilling machine and fed into the device similarly to the first. Then the device is unloaded and the cycle of operation is repeated.

For normal operation of the device, the compression forces of the springs 16 must exceed the compression forces of the springs 23 of the clips. Limiters 21 limit the angles of rotation of the levers 15 and contribute to the symmetrical placement of the rollers 20 relative to the carriage 3.

Thus, the application of the proposed device on a drilling machine fully mechanizes the processes of building up and dismantling the lamp rods, which increases the safety of the staff. At the same time, the maintenance personnel approaches the machine from the control panel only for loading or unloading the feeder, which does not require turning the machine into operation. This is very important when drilling wells in coal seams, dangerous sudden outbursts of coal and gas, and rock bursts.

The device contributes to improving the efficiency of drilling operations by ensuring the remote control of works on increasing and dismantling the rods.
