Description

The proposed drilling machine, according to the inventor, is a simplified equipment for the production of percussion wire drilling to a depth of 60-80 meters, with any number of beats per minute and any height of the bit.

The machine can be made in the form of disassembled parts, assembled at the work site and fixed directly on the legs of the copra, which is a known convenience for transportation. In the case of reinforcement of the drum on a special bed, the structure can serve as a machine for percussion drilling.

In FIG. 1 is a longitudinal sectional view of the drilling machine; FIG. 2 is the same side; Fig- 3-axis with a partial section; FIG. 4 is the same side; FIG. 5-hollow axis in longitudinal section; FIG. b the same, in a cross-section; FIG. , 7-section along the line AA in FIG. one; Fig.8-10-plate in different projections; FIG. 11 is a view of a device for moving the axle from the front; 12, too, on the side.

The shaft 7, resting on the bearings 2, has a full-length hole in which the axis / b is moving freely to the right and left. In the shaft 7 along the generatrix there are two paired rigs (127)

BEjpesa 15-15 with inserts in them with dies 5, pr-si 5aekyu.and to drum 8 by means of conical notches -6 on axis 16 while moving it to the right. FIG. 1 axle 16 is set into the left extreme position, and the plates 5 are moved apart, entered into the corresponding slots of the drum 8 and, thus, the drum is in engagement with the shaft 7, on which a pulley 1 on the key, causing the drum to rotate. The axis 16 moves to the right and to the left by levers 11 connected to a conversion sleeve 10, tightly seated on axis 16. The idling of the bit, i.e., it is lifted by drum 8, using pulley 7, shaft 7, dies 5 pushed out 16 and entered into the slot of the drum 8. The working stroke of the bit, i.e. its fall to the bottom of a well, is made by self-falling. The axis / o, being moved to the extreme right position, will release the plates 5 and they, coming out of the slots of drum 6, will separate it with breaking 7 and, under the force of the bit weight, it will rotate in the opposite direction. In order to save the rope from unnecessary unwinding, a foot brake 13 is arranged on the right, which, through the belt 2 and the brake wheel 9 tightly connected to the drum, allows the drum to be retained. In order to facilitate the rotation of the drum towards the working stroke, the latter is on two ball bearings 4 protected from the cheeks 3 of the drum 8. The pulley 7, depending on the desired number of revolutions of the drum, can be replaced by a gear.

In order for the cloaks 5 to be freely lowered and raised, in the conical undercuts 6 there are slots along the cone forming a section, along which, as the axis moves, the plates 5 slide.

The subject matter of the invention.

9, in order to notify the drilling tool of a free fall, a winch is used, having a hollow shaft 7 with two pairs of rectangular cuts 75-75 with dies 5 inserted in them pressed to the drum by means of tapered notches 6-6 on the axis / 5 while moving it 1 to the right, and for moving the axis 75 to the right or left are the levers 77 acting on the conversion sleeve 7tf, fastened to the axis 76.
