Description

In percussion drilling, alansis impact percussion machines are used with a device for balancing a drilling tool and with a balancing tool in the form of a worm gear gear.

In the proposed machine, related to the specified type of machine tools, a drum is used, which is intended both for lifting and lowering the tool and for drilling, hooking up with the gear of the shaft for lifting and lowering, or the drill shaft, for which the drum shaft can be moved to

In FIG. 1. shows a side view of the machine; FIG. 2 is a top view of the machine with a partial section and FIG. 3 is a front view.

On the frame / in its front part there are reinforced guides 2 of iron bars supported by iron-resistant 3; On the frame of the machine, in its middle part, on three sub-holders 4 there is a main shaft 5 of square shape, which is worn gear 6, a friction pulley 7 and the brake disc 8, with the gear wheel moving freely along the shaft with the aid of a strap 9. The main shaft 5 with the help of a movable gear 6 stays with gear /, jammed on

1386

the drill shaft 7 /, bearing, mounted on the lower frame of the machine; Cranks 12 are fastened at both ends of the drill shaft 77, connected by means of connecting rods 13 to a lifting shaft 14 on the last drum 75c mounted with gear / b. The shaft 14, when drilling, goes, up and down along the guides 2, having locks at the ends (not shown in the drawing), which can be used to hold the shaft in place with the help of a clearing. At the end of one connecting rod 13 there is a worm gear 77, which with the help of a wedge on the arc 18 can be attached to the shaft 14. At the rear of the machine, the counterweight 22 is hinged. A rope connected to the counterweight is passed through the rollers 20, in those cases When the drilling tool is longer than the shaft 14 with all its parts, the rope is passed through the rollers 21.

When the tool is lowered and ascended, gear 6 is engaged with gear 76 by means of a strip 9; locks wedge a lifting shaft 14 in the lower part of the guides; the worm gear is disconnected, after which the drilling tool is raised or lowered. After the tool reaches the bottom of the well, with a wedge along the arc 18

the worm is connected to the shaft 14, thereby stopping the rotational movement of the drum; With the aid of the strap 9, the gear wheel 6 engages with the gear wheel J O, the locks on the steering wheels swing back, the main shaft 5 receives a rotational movement from any engine and through the gears and connecting rods drives the shaft 14 which moves on the rollers along the guide 2 up and down and produces crushing .X During operation, rotating the screw kg, you can rotate the drum in one direction or the other and adjust the length of the rope as the bit deepens. At the end of the work, wedges are inserted into the locks, on the guides, gear 6 is unwound with gear 10 and interlocks with gear 16, after which the worm gear is disconnected and the machine is ready to lift the tool.

The machine can. work rope and rods; can produce drilling, cutting casing, cleaning plugs and in general all the work required when

drilling. If desired, you can install an additional shaft for installing a drum for cleaning wells. V

In the flock there is no balancer, which is played by the movement of the shaft 14 along the guides, as well as the equalization screw, replaced by a worm gear.

The subject matter of the invention.

An unbalanced percussion drilling machine with a tool for balancing a drilling tool and a leveling device in the form of a worm gear, characterized by the use of a drum 15, which serves, if desired, for lifting and lowering the tool and for drilling, namely; when the gear 6 of the main shaft 5 is connected with the drum gear / b, 75 - for lifting and lowering, and when the gear 6 is connected with the gear 10 of the drill shaft 77-to communicate the forward-return motion to the drum, the drum shaft 14 moves along the guides 2 .
