Abstract

The drilling system has a reduction gear unit (1) at the head of a slideway support (5), transmitting a rotation from a motor (3) to a rotary bar (4) on which a second reduction gear unit (7) with hollow shafts slides. One hollow shaft contains needle bearings at one end and a rod (9) and injection head (8) at the other to remove sediment from the hole being drilling. The unit also has two power cylinders (12, 17) to extend the slideway and lift it with the aid of a cable (18). The drive motor (3) can be electrically, hydraulically or pneumatically operated.

Title of the invention, DRILL, WITH SLIDING REDUCER. The principle, of the drilling machine; with sliding reducer, consists in adapting, a reduction reducer (1), fixed at the top of the support column (5) and assembled, to the support horizontal (2); this rotation reducer (l) also receives any principle of rotation (3), ie, electro
pole, hydraulic, or pneumatic; which transmits rotation through the
reduction gear (l) on the rotation bar (4); contained in the chassis
slide, extendable (5), on this rotation bar, (4) slide
a pendulum reducer, with hollow shaft, of rotation (7) rod holder
which are adapted, on the rotation head (9); which crosses, the shaft
hollow, of the reducer (7), and is adapted, at its end, to a head
injection (8), which allows the passage of circulation elements
which are used to remove the sediment from the borehole; the plate
support (6) which slides on the slide frame (5) supported by the
assembly plate (l0) integral with the rod holder reducer (7) for
allow the rigidity of this assembly; the jack attachment (ll) to,
which fits the cylinder rod (l2), contained in the guide (l3)
which is used to guide the slide frame (5); to allow it
extension, upwards; this allows drilling rods to be placed
longer, the rod guide (l4) is also used to receive the key
unscrewing the rods; in its notch, the stabilizing plate
sation (l5), supports this assembly; the rear guide (l6), serves to
rigidity, of the slide (5); the jack (l7), used for lifting the reduc
- rod holder (7), by lifting the lifting cable (l8), suitable
to the tensioner (l9), this assembly; rolling on deSpoulies, stadaptant;
at the other end, on the plate (6); in (20) needle bearings
which allow the sliding of the bar (4) in the hollow axis (7)
the processes used, i.e. slides (111 and 6) cylinder (l2) for slides
expandable seat, as well as needle bearings (20) of the bar,
of rotation, are to be taken into consideration for the use
practical sliding system.
