    and mounted on a cylindrical groove of a drilling rig having a flange. The clamping device is made in the form of eccentric wheels (EC) 13 with toothed rims 18 and with their gearing more than 1 cm. It is made in the form of toothed racks 17 connected to an axial displacement, which is a power cylinder 23. Its rod 24 is connected to a cylindrical support ring 19. The rails 17 are placed in K 9 parallel to the axis of the hole 10. Moreover, the EC 13 is placed in K 9 is diametrically opposite to open1
    This invention relates to a mining industry, in particular to mechanisms for uncoupling a drill rod with a drilling machine.
    The purpose of the invention is to improve productivity by simplifying the process of boom buildup during drilling and by reducing the time for auxiliary operations.
    FIG. 1 is a diagram of a drilling machine with a tripping mechanism, a general view; 2 shows the tripping mechanism, side view; on fig.Z - the same, view along arrow B, on figure 2; figure 4 - front krshka drill rig; FIG. 3 shows the connection of the tripping mechanism to the front of the drilling machine in the locked position.
    The drilling rig 1 is mounted on the slide 2, which moves along the feed beam 3. The front rim 4 of the drilling rig supports the tripping mechanism 5. The drill rod 6 includes successively located drill rods 6 a, 6 b, interconnected by a threaded connection. The rod closest to the drilling machine is screwed into the shank of the drilling rod 7 mounted on the drilling machine with the possibility of rotation. A clamping guide 8 for the drill rod is installed at the opposite end of the feed beam 3.
    The uncoupling mechanism 5 consists of a housing 9, which has a central
    ten, and their axes are mutually perpendicular. During operation, the ring 19 is pulled away from K 9 and the rails 17, interacting with the rims 18, turning the EC 13, locking the K 9. Next, the EC 13 is blocked by the drill rod. When the shank is rotated, the movement of K 9 relative to the rods is prevented by the flange. Unscrewing of the rod parts occurs. When unscrewing them from the shank, the rod is blocked. As a result, the EC 13 is disconnected, and the K 9 is immobile. The shank then rotates. 4 hp f-ly. 5 ils

    the through hole 10 of the bearing housing 11 located coaxially with the hole into which the annular bearing I 2 is inserted. On diametrically opposite sides of the aperture 10 in the housing 9 on the ala 14, the eccentric wheels 13 are rotatably mounted. 14 are arranged perpendicular to the plane passing through the axis A of the housing.
    In the case, parallel to the axis A, holes 15 are installed, in which the rods 16 are installed with the possibility of sliding. At one end of the rods 16 there are jagged rails 17 that are in engagement with the toothed rim; 18, made on eccentric wheels 13. Opposite ends of the bias rods are attached to a cylindrical support ring 19, which is rotatably mounted on the bias ring 20. The lower part of the bias ring is provided with a carriage 21, which slides along the guides 22 on a sled 2, the carriage with the power cylinder 23 mounted on the sled, by
    stock 24.

    The body of the drilling machine is made with a cylindrical groove 25 and a central through hole 26. Chezs

    when the front cap is fixed on the frame of the drilling machine 1. The outer surface of the cylindrical bore is the working surface 27 for the bearing 12 of the sliding mechanism of the uncoupling.
    An annular flange 29 is attached to the end of the cylindrical groove of the front trim with bolts 28. The flange 29 rests against the end of the bearing 12 and prevents it from sliding. sliding in the axial direction of the body.
    The uncoupling mechanism works in the least way.
    The release mechanism housing is rotatably mounted, but without the possibility of movement in the axial direction. The drill rod 6a is held in the housing and secured to the shank of the drill rod 7 of the drilling machine by means of a threaded joint. The shank of the drill rod is rotatably mounted, but cannot move axially relative to the housing. The front blade is attached to the body of the drilling rig, which is mounted on the slide 2 without the possibility of axial displacement and rotation.
    .
    When the carriage 21 is displaced by means of the ram 23 toward this cylinder, the support ring 19 is pulled away from the housing 9 by the bias ring 20, thereby the bias rods 16 are moved in the corresponding holes Q and their gears turn the eccentric wheels counterclockwise, translation they are in the case of blocking the body and are engaged in the grip 35
    with a drill rod 6a, is located by simplifying the process
    in the hole 10, they block the drill rod, preventing it from moving in the axial direction and rotating relative to the body. At the slightest movement of the drill rod 50 in the axial direction, its further jamming between the eccentric wheels occurs.
    When the shank of the drill rod turns in the direction in which the drill rod tends to unscrew from it, the unscrewing is prevented due to the fact that the sliding bearing 12 connects the boom rotation during drilling and shortens the time for auxiliary operations, the release mechanism casing is installed rotation relative to the body of the drilling machine and connected to the latter by means of an annular bearing coaxial to the hole for the drill rod mounted on the cylindrical bore in Finished on the body of the drilling machine and having a stop flange for securing the body of the tripping mechanism in the axial direction relative to the body of the drilling machine.

    the body frame abuts against the holding flange 28 of the front bolt, preventing movement in the axial direction of the housing relative to the front hook and, therefore, also relative to the drill rod. The consequence of this is that the drill rod is blocked without the possibility of rotation on the shank of the drill rod. This locking has the advantage of allowing the drill rod 6 q to be unscrewed from the drill rod 6, which was blocked without rotation by means of the clamping guide 8.
    When it is necessary to screw or unscrew the drill rod 6a from the shank of the drill rod, it is locked without rotation by means of a clamping guide and is eccentric: the e wheels of the uncoupling mechanism are kept in a disconnected position, thus the body remains stationary in a certain position, while time as the shank of the drill rod is rotated. This situation is repeated during the drilling process, and the clamping guide serves only to guide the drilling hose 6a.
