    PCT No. PCT/FI81/00045 Sec. 371 Date Feb. 12, 1982 Sec. 102(e) Date Feb. 12, 1982 PCT Filed Jun. 12, 1981 PCT Pub. No. WO82/00171 PCT Pub. Date Jan. 21, 1982.A drill steel guiding and centralizing mechanism comprising a body (14) and a first and second jaw (1 and 6) connected to other ends of two-armed angled levers (2,3 and 7,8). The angled levers are turnably connected to the body (14) by joints (4 and 9) at the corner points between the arms (2 and 3; 7 and 8). The ends of the free arms (3 and 8) of the angled levers are connected to each other by a connecting road (11), the ends of which are connected to the ends of the arms (3 and 8) by swivel joints (12 and 13). The second angled lever (2,3) has an extension (16) which is affected by the power mechanism (15) substantially parallelly to the connecting rod (11). Thereby the jaws (1 and 6) can be opened and closed by the power mechanism (15) exactly centralized in relation to the drill steel.

    The invention relates to the field of mining, namely to guides and centering devices of boring tools.
    The purpose of the invention is to improve the accuracy of the joint and the rods of different diameters.
    The drawing shows the kinematic scheme of the mechanism.
    The mechanism includes cams 1 and 2 for guiding and centering the drill (shown i close position). The cam 1 is connected to one shoulder of the cranked lever 3, KOTopiiiii also has another shoulder and a protrusion 4. The cranked lever 3 is fixed on the housing 5 by a swivel 6 between the arms of the lever.
    The other cam 2 is connected to another crank lever 7, which also contains two arms. If they are placed a hinge joint 8, by means of which the knee lever 7 is laterally fastened 1: 1 on the housing 5. The radius of the opening of the cams along the line of the neiiTjsa drill can be chosen, for example, to attach the extension rods to the connecting coupling, In this case, the cams, ie, cr.; And ak1ts with each other.
    The arms of the crankshafts 3 and 7 are connected by a rigid connecting rod 9, which is attached to the arms shoulders by hinged joints 10 and 11. The hinges 10 and 11 and the joints 6 and 8 are preferably placed at the angles of the parallelogram. The protrusion 4 is removed from the power drive 12 of the device, the other end of the said drive is connected to the housing 5. The drive can be connected to operate any shoulders or connecting rod 9.
    When the piston of the actuator 12 is extended, the cams 1 and 2 open symmetrically relative to the central line

    borax. If the lengths of both arms carrying the cams are equal, the movement path of both cams is the same. Thus, the accuracy of the centering of the cams is good even if the cams do not touch each other in the closed position, for example, when the cams for the extension rods are captured by these cams. Because the cams open symmetrically, they are also acceptable for pipe installation. By mutually adjusting the dimensions between the hinges, the amount of movement of the cams and the compression force is varied.

    Invention Formula
    A mechanism for guiding and centering drill rods, comprising a body, two double-arm levers, two
    centering jaws, each of which is placed on a respective two-arm lever, and each of the two-arm levers are secured by a central support hinge on the housing, and a power drive that is articulated with one arm of one of the two-arm levers, distinguished by the fact that, in order to increase the accuracy of the coupling arms different diameter
    the levers are articulated, and the shoulders opposite to the shoulders bearing the centering cams are connected to each other by means of a connecting rod connected to the specified levers by hinges, while the joints of the two shoulders connecting the body and the connecting rod are located at the vertices of the parallelogram, the shoulders bearing cams have
    the same length, and the center of the cams in their closed position lies on the line connecting the central hinges,
