Description

In a drilling machine with a spring machine for transferring all changes occurring at the bottom of the well to the mechanism producing a rope feed, the inventor proposes to install the rope drum freely onto the curvilinear shaft, and the hard-wheel gear that is in internal engagement with the other gear which by means of the worm shaft is driven into rotation by a separate engine.

In FIG. 1 is a view of a drilling machine with a partial cut along the line AB in FIG. 2; FIG. 2 is a side view of the machine, partially cut along the line MN in FIG. one.

A drum A with a gear wheel B rigidly attached to it, which is in internal engagement with the bristles C, which diameter is twice as large as the gear diameter V., is loosely mounted on the curvilinear shaft of the impact drilling machine (Fig. 1, 2): Gear C on the outer surface is carried by teeth, with which it is engaged with the worm shaft Wi,

linked using gears with a separate engine. Gear C is fixed to the bed by tides E separated from the bed body to reduce wear by bronze rings (inserts).

The impact of the proposed machine is based on the rotation of the center of the drum A together with the eccentric shaft IV, and the drum A itself does not rotate near the shaft I, due to the fact that the diameter of the pinion C is twice the diameter of the pinion B.

f The subject invention.

A spring percussion drilling machine for transferring to the mechanism, which feeds the rope, all changes occurring at the bottom of the well, characterized in that the cable drum A of the percussion winder with a gear 5 rigidly attached to it is mounted on a curvilinear shaft, and wheel B It is located in the internal engagement with the pinhole C, the outer surface of which is provided with teeth to obtain movement through the worm shaft from a separate jigger. to the author's certificate of V.N.
