Drilling rig

 

(57) Abstract:

The invention relates to the mining industry, namely drilling machines. The machine includes a transport base, a mast with guides and stops at the top due to the rods of the power cylinders feeder mounted on the movable rotator, becoming drilling, hoisting winch, rope and rope blocks. Stops at the top links are movable with the possibility of output from the zone of action of the rods of the power cylinders feed and rigidly connected with the axles are pivotally connected with a thrust and a cylinder rod placed on the mast. The spindle axis is spring-loaded. The invention provides reduction of time for auxiliary operations. 1 C.p. f-crystals, 3 ill.

The invention relates to the mining industry, namely, drilling machines, and can be used for drilling blast holes for various purposes.

Known drilling machine, comprising a transport base, the mast guides, rotator installed with the possibility of axial movement, lifting winch, rope and rope blocks (see 40 C., Katanov B. A., Sathin M. C. Machines rotary drilling in coal mines. - Gosgortechnadzor. - 1960, is 147 C.)

The disadvantage of this machine bookmark reduces the speed drilling hard formations due to the lack of additional axial pressure on the face.

Also known drilling machine, comprising a rotator mounted for axial movement along the guide rails rigidly connected with movable arms and covering power cylinders, connecting the movable beam with a fixed (and.with. The USSR 1073449, CL E 21 In 3/02, 1984).

The disadvantage of this machine is in low speed drilling soft rock because deterrence feed drill rod with the rotator, as the rods of the power cylinders have a constant supply of kinematic connection with the mast of the machine and do not provide a free feed when drilling in soft rock.

The closest is a drilling machine, comprising a transport base, a mast with guides and stops at the top due to the rods of the power cylinders feeder mounted on the movable rotator installed with the possibility of axial movement along the guides, becoming drilling, hoisting winch, rope and rope blocks (see S. 22, M. C. Sapogin. B. A. Kachanov. The operator of the drilling machine on the career. - M.: Nedra, 1984. - 308 C.). The machine can equally successfully to drill breed any strength using free or forced (using rods of the power cylinders of plusgiro supply, retractable stops to Verhny performance when drilling hard formations in connection with the use of the full stroke of the piston rods of the power cylinders feed resting in a special fixed stops (tides) and the upper connection of the mast of the machine that requires waiting idle rods (retraction of the rod under its own weight) cylinders for carrying out the process of the overwind rotator by means of a lifting winch for building the next links in the rod.

The claimed technical solution aimed at solving the problem - reduction of time of auxiliary operations by performing the moving stops.

This is achieved by the fact that in a drilling machine, comprising a transport base, a mast with guides and stops at the top due to the rods of the power cylinders feeder mounted on the movable rotator installed with the possibility of axial movement along the guides, becoming drilling, hoisting winch, rope and rope blocks, supports for the rods of the power cylinders of the filing is made movable with the possibility of output from the zone of action of the rods. When this stops rigidly connected with the axles are pivotally connected with the mast of the machine, and the axis associated with the thrust and piston rod of the power cylinder control placed on the mast of the machine, the cylinder rod relative to the axis of the spring-loaded.

In Fig.1 shows a General view of the drilling machine (the end of BU is, 3 - the General scheme of the management of movable stops.

The drilling machine includes a transport base 1, the mast 2 with the guides 3 and 4 stops in the upper connection 5 for the rod 6 power feed cylinder 7 mounted on the movable rotator 8 installed with the possibility of axial movement along the guide rails 3, the drill became 9, hoisting winch 10, the rope 11 and the cable blocks 12. Stops 4 in the upper link 5 is made movable with the possibility of withdrawal from the zone of action of the rods 6. When this stops 4 are rigidly connected to the axles 13 are pivotally connected with the mast 2 of the machine, the axis 13 are connected with a pull of 14 and rod 15 of the cylinder 16, is placed on the mast 2, and the piston rod 15 of the cylinder 16 with respect to axis 13 is spring-loaded 17.

The machine works as follows. At the beginning of the drilling of the power cylinder control 16 is locked and its shaft 15 through the axis 13 and rod 14 holds the lugs 4 at the upper connection 5 of the mast 2 in the zone of action of the rods 6 of the power cylinder 7 of the rotator 8. When drilling hard rock rods 6 power cylinders 7 are put forward and rest against the stops 4, creating additional pressure on the rig becoming 9. After drilling to a depth of one link rod cavity of the power cylinder 7 are connected to a drain line, and stops 4 with the rod 15 power cyl the stroma of the rise of the latter by means of the lifting winch 10 and the rope 11 through the cable blocks 12 in the operations on the movement of parts of the composition.

However due to the presence of the compensation spring 17 at the junction of the stem 15 of the power cylinder 16 with the axis 13, the rod 15 when the pressing rod 6 of the power cylinder 7 at stops 4 is not subjected to deformation.

1. The drilling machine includes a transport base, a mast with guides and stops at the top due to the rods of the power cylinders feeder mounted on the movable rotator installed with the possibility of axial movement along the guides, becoming drilling, hoisting winch, rope and rope blocks, characterized in that the supports for the rods of the power cylinders of the filing is made movable with the possibility of output from the zone of action of the rods of the power cylinders.

2. The machine under item 1, characterized in that the stops are connected with the axles are pivotally connected with the mast of the machine, with the axis associated with the thrust and piston rod of the power cylinder control placed on the mast of the machine, and the cylinder rod relative to the axis of the spring-loaded.
