(54) DRILLING MACHINE FOR DRILLING FAN

one

The invention relates to the mining industry, in particular to drilling rigs, intended for drilling a fan of wells in underground conditions.

Known drilling machine, including the feeder, rotator, drive gearbox, mounting frame, swivel bearings and bevel gear mounted in the swivel bearings between the feed mechanism and the driven gear 1.

For the specified machine, a small area of pr-name and low maintenance safety are characteristic.

Closest to the invention to the technical essence and the achieved result is a drilling machine for drilling a borehole fan, comprising a self-propelled engine, a body pivotally connected to the body of the rotation mechanism, on the axis of which an boom with an actuator is installed, the boom tilt power cylinder fixed by one end on the body of the drilling machine, and spacer jacks 2. However, this machine is also characterized by insufficient field of use and increased risk of work. WELLS

The purpose of the invention is to expand its field of application and increase the safety of work.

To achieve this goal, a drilling machine for drilling a borehole fan, comprising a self-propelled chassis, a housing pivotally connected to the housing of the rotation mechanism, on the axis of which an boom with an actuator is installed, a power cylinder for boom rotation fixed at one end to the drilling rig body, and

10 spacer jacks, equipped with an axle-mounted lever with splined clamps and splined crowns at the ends, a splined flange fixed at the end of the axis, and a splined crown fixed to the body of the rotation mechanism, while the splined clips have a drive for their engagement with splined flange and slotted clip, and the lever is pivotally connected to the power cylinder turning the boom.

In addition, the movement drive of the slot 20 of the clips is made in the form of power cylinders, which are fixed on the lever.

FIG. 1 shows a drilling rig when drilling a circular fan of wells, the vertical position; in fig. 2 - the same horizontal position; in fig. 3 shows section A-A in FIG. one ; in fig. 4 shows a section BB in FIG. 1. The drilling machine includes a housing 1, a self-propelled chassis 2, a turning mechanism consisting of a housing 3, paired power cylinders 4, a gear wheel 5, which is engaged with gear racks 6, at the ends of which are made pistons 7 located in power cylinders 4, and the axis 8 installed in the housing 3. The housings (not shown) of the power cylinders 4 are connected to the housings 9 of the spacer docks equipped with sliding parts 10. On the end of the swivel mechanism axis 8 facing to the face there is an arrow 11 with actuators. m body 12. At the other end of the axis 8 along the lever 13, on which the slotted rims 14 and 15 are made, and the slotted flange 16 is mounted. The slotted rims 14 and 15 are fitted with slotted shafts 17 and 18 with the possibility of movement under the action of the power cylinders 19 and 20, one ends of which are fixed on the lever 13, and the others on the yokes 17 and 18. A rigidly splined crown 21 is connected to the housing 3 of the pivoting mechanism. The lever 13 is connected by means of the joint 22 to the bracket 23, and by means of the hinge 24 to the power cylinder 25. The bracket 23 and the power cylinder 25 of the boom tilting installed on the body 1 of the drilling machine. The drilling machine works as follows. Before drilling a circular fan of wells in a vertical plane, the mechanism of rotation of the drilling machine with the help of sliding parts of 10 spacer jacks “is bursting between the roof and the sub-basement. Then, with the help of the power cylinder 20, the spline holder 17 is engaged with the splined crown 21, and after the power cylinder 19 is disengaged from the slanted flange 16, the splined holder 18. Thereafter, in the opposite cavities of the power cylinders 4 the energy carrier is fed, under the action of which the pistons 7 and the gear bars 6 rotate the gear wheel 5 together with the axis 8, the boom 11; i by the executive body 12 until the latter is installed on the well. Having installed the actuator 12 on the well, the slotted sleeve 18 is engaged in engagement with the slotted flange 16, preventing the axis 8 with the boom 11 from rotating relative to the lever 13, and proceeds to drilling. Before drilling in the horizontal plane, the sliding parts 10 of the spacer jacks are removed and, using a power cylinder 25, rotate relative to the hinge 22, the lever 13 together with the turning mechanism and boom 11. Then the splined yoke 18 is engaged with the splined flange 16, and the splined yoke 17 leads t from engagement with the spline crown 21. This prevents the axis 8 from rotating relative to the lever 13 (and therefore the casing 1). After that, in the cavity of the power cylinders 4, an energy carrier is supplied, under the action of which the toothed racks 6 are set in motion, rolling on the stationary cog wheel 5 and turning the expansion jacks relative to the fixed axis 8 until the sliding parts 10 of the expansion jacks installed at a right angle to the side walls of the excavation. Then, with the help of sliding parts 10 of the spacer jacks, the rotation mechanism between the side walls of the excavation is pushed, the spline holder 17 is in engagement with the slider ring 21, and the clip 18 from engagement with the slit flange 16 and energy is fed into the opposite cavities of the force cylinders 4 until the boom with the executive body, carried along axis 8, is installed on the well. After that, the slotted yoke 18 is engaged with the slotted flange 18 and proceeds to drilling. To drill a circular fan of boreholes in an inclined plane, the boom 11 with the executive organ. 12 "is filled up with the help of the power cylinder 25 at the desired angle," the rotation mechanism between the side walls of the excavation is pushed and the actuator is installed on the well. The dimensions of the toothed rails 6 and the power cylinders 4 provide rotation of the gear wheel 5 within 360 °. This makes it possible to drill a circular fan of wells. In comparison with the known, the proposed drilling rig allows drilling a circular fan of wells in horizontal, vertical and inclined planes, and also provides reliable ramming, mechanical blocking of the boom from turning during drilling. Claim 1. Drilling machine for drilling a fan of boreholes containing a self-driving valve, body pivotally connected to the body of the steering mechanism, on the axis of which there is an arrow with an actuator, power cylinder of the boom tilting, fixed at one end to the body of the drilling machine, and spacers hydraulic jacks, characterized in that, in order to widen its application area and increase the safety of work, the drilling rig is equipped with an axle-mounted lever with splined clamps and slotted rims at the ends, schlitsevym Lanz zakreplenny.m on the end of the shaft, and schlitsevym ventso.m fixed to housing rotation mechanism, the yoke schlitsevye are driven for their engagement respectively with splined flange and the slotted cage, and a lever pivotally connected to the tilt boom power cylinder. 2. Machine on c. 1, characterized in that the drive for movement of the spline clips is made in the form of power cylinders which are fixed on the lever.
