1- an electric motor at 220 volts (A) positioned in horizontal way for the model to "Cingia of Toothed transmission (D) and fixed to the machine body (G) by means of four threaded rods which also allow the adjustment of the tension of the transmission belt (D) itself;

2- a Transmission Group (B) composed of a small toothed belt driven by the electric motor (A) that transmits the primaiy motion to a pulley for rotation speed reduction, integral with the Transmission Group (B); this pulley rotates integrally with a splined shaft on which installed and another pulley which transmits the motion to the Toothed transmission belt for long neoprene (D) stretched between this pulley to the pulley mail in Forante Group bottom (E); the sliding splined shaft allows the pulley, which transmits the motion to the lower one, of being able to freely move forward or backward in order to follow the movements transmitted by the long Toothed Transmission Belt (D) to Forante Group (E) when this slipped and moves back to back drilling;

3- a Group Commands (C) which controls the compressed air supply suitable to operate both the positioning of the Actuators double effect of stabilization (F) is the advancement at a controlled pressure of Forante Group (E) so that it can make the hole with a calibrated feed both as regards the cup holing (drill bit) for both the material to be drilled;

4- a neoprene toothed transmission belt (D) long, which transmits the motion from the pulley on the shaft placed at the top of the Transmission Group (B) to Forante Group (E) located at the bottom; it is adjustable by 4 filettae inbullonate bars and the Body Machine (G) where this forms the basis of the electric motor (A);

5- a Forante Group (E) consists of a grooved shaft (positioned on two hermetic pads) on which is fixed frontally cup holing (drill bit); Rights to this is fixed integrally to the pulley, through Toothed belt (D), it transmits the motion that allows you to make the hole; the Forante Group (E) performs a feed movement and retraction of the holing cup sliding with the bushings of 4 steel guides fixed to the machine body (G) and its thrust forward and backward is generated by 2 Actuators dual effect places the sides of the same group and are controlled in 2 directions from the commands group (C); the cup holing (drill bit) which is the only component subject to wear due to drilling work is easy to replace as frontally fixed on the shaft of holing group from the inside of the same cup with a fastening nut which is screwed through a thread made of grooved shaft transmission;

6- 4 Actuators double effect (F) which are fixed to the underside of the machine body (G) via a metallic container open at the bottom; said actuators allow the stabilization and locking the core drilling machine in the wells to be drilled and this independently from the internal dimensions of the cockpit;

7- a Machine Body (G) which is made of perforated and folded metal material, with a rear portion removably fixed with the screws with the removal of which it is possible to access the operating component called by the machine itself or to the replacement of Toothed Belt (D) . 2


"DRILLING MACHINE CORNER STATIC", according to previous claim, where the transmission Toothed belt (D) is replaced by:

1- a Angular Referral (B) that is driven more and generated by the motor (A) (always placed in horizontal mode) via a direct link;

2- a Tree of Transmission Telescopic (D) connected to the Goal corners (B) which in turn in the lower side is connected to a bevel gear pair or another angular transmission (in accordance with the drilling effort of the various materials) for the transmission of the motion to the drilling Forante Group (E); the transmission shaft (D) is a telescopic shaft which allows the elongation and retraction of the same in order to be able to follow the advancement and the retraction of the holing group;


"DRILLING MACHINE CORNER STATIC", according to previous claim, where transmission through Referral corners (B) is amended as follows:

1- the electric motor (A), always of equal power, rather than in horizontal way is vertically mounted above the machine housing (G) and this to enable further working torque for particularly hard materials; the motion is then transmitted directly and vertically to the Tree of Telescopic Transmission (D) from

2- an axial Cardan joint (B) which transmits motion directly and vertically to the Tree of Telescopic Transmission (D) and allows to follow in an articulated manner the movement of the Tree of used transmission when the Forante Group (E) performs the 'progress or arretratura to drill the hole.




The overriding objective of this invention is to provide holes of various sizes both on walls that are on the wall, ceiling, or floor is on cement already installed on site (conducted cementitious type of liquid as irrigation pipes, wells of waste water, pipes of various gender,) without that to do this they must remove from where they are installed or replaced with other already drilled. In fact, having the peculiarity of being able to intervene directly on the site where there was a need, the intervention will be extremely rapid, immediate and above all very cheap. The invention is intended for use primarily in technical-building field but also usable in other fields which require the construction of special calibrated holes and can also be regarded as a rapid intervention machinery in cases of emergencies like clogged drains or wells without having to first provide all'evaquazione of water waste still present. The machine in question is particularly dedicated to the final solution of a big problem related to the presence of the exhaust wells wastewater positioned along all roads (so-called "exhaust manholes") which currently are provided with a "siphon" irremovable; this particular construction, designed to prevent leakage of odors from the main sewer, when clogging of the "trap" itself (which is extremely common due to the presence on the streets blocking materials such as leaves, paper, cigarette filters etc!) DO NOT allow to carry out a proper cleaning and removal of bulky materials resulting in flooding of the streets! It makes it so necessary to replace the existing wells with the products made only more recently and equipped with "trap" removable; Obviously all this involves considerable intervention costs and significant disruption to traffic. The present invention (currently absolutely NOT present on the market!) Allows to avoid the costly intervention of the total exhaust cockpit replacement with the creation of a hole in the inner part of the cockpit itself so as to temporarily by-pass the "siphon" and so to allow the instantaneous mass in the cockpit communication (flooded or not!) with the sewage discharge system (allowing the immediate flow of stagnant water!) and subsequent cleaning of the "trap" on the side of the discharge which is otherwise impossible. One of the main problems of the exhaust wells is their reduced internal dimension, which varies from 25x25 cm. of the older wells (which currently represent the greatest number!) up to those 40x40 cm., and then it is evident that any amending intervention of their structure appears to be nearly impossible with current equipment present on the market; it goes without saying that the present invention overcomes any modification and maintenance problematic having a tripping operation with two basic characteristics:

the possibility to realize the holes in an angular way;

its remarkable compactness (cm. 24x24!) which allows it to make the necessary changes to all wells currently present, from the smallest to the biggest ones.

The use of this machine is extremely simple given shows that when you have to intervene in a drainage sump proceed in the following way: it arrives in proximity of the same with the means of transport on which the machine is installed transport aid of a small electric crane to always installed flag on the transport pallet, is extracted the core drilling machine (G) and is drawn into the cockpit; after locating the exact spot to be drilled and is provided to lock the machine inside the cockpit via four Actuators Double-acting (F) moved from Controls Group (C) on the front of the machine; at this point having the coring machine in working position starts the rotatito movement of the drilling cup, said "drill bit"; He said working motion is impressed by the electric motor (A) which via the transmission unit (B) moves a Toothed Belt Neoprene (D) which transmits the rotary movement to Forante Group (E); at this point via the Controls Group (C) starts the advance of Forante Group (E) with its rotary motion creates the hole; the feed and the subsequent retraction of the holing cup takes place with the use of two double acting Actuators (F) placed in the compartment at the bottom where they are housed.

This innovative invention is mainly characterized in that in the part directly operating of this tool, that is, in the realization of the required holes, there are no exposed electrical parts in work areas at the same gives the possibility to operate also in damp areas or even, in When used in concrete pipes or wells, also in the presence of water; In fact, the electric motor (A) which is fitted for its funzionamente is placed far away from the actual point of intervention and thus without danger to the operator; then if one takes into account that, as mentioned, the operator intervenes only during the positioning phase, start-up and removal, it is evident the extreme security ensures that the same operator.

As regards the industrial utilization, it is noted that the present invention has an extremely wide application, just think for example in irrigation systems or ducts of liquids am / cement pipes to the possibility of building new derivation holes on the walls of the same , from the inside outwards, at any point there is the need of having to do without having to remove and replace whole pieces of the same plant; but the predominant reason of its design and construction derives from its undeniable possibility of use when the need arises to carry out maintenance in the exhaust wells wastewater fitted with concrete siphon, maintenance that currently it is impossible to maintain it if not replacing the cockpit with a another already prediposto of "siphon" removable inspection, all with a considerable economic cost and timing of a very long speech; as noted above, with the present invention with "operation ANGLE" instead of the intervention can be immediate, estremammente fast, immediately decisive and definitely very, very, cheap; the present invention is also innovative and especially the characteristic of being able to operate also in the wells already flooded and this makes it useful estremammente along streets already flooded due siphons of totally obstructed by various wells materials such as leaves, waste papers, but above all the filters of the cigarettes together with the rest and to the outflow of soil create a real "wall" of remarkable consistency and almost impossible to remove. In the case of having to make holes in walls, floors or ceilings, the invention demonstrates its versatility and safety intervention since after placing the machine and properly shored, is being carried out in absolute safety for the operators. The present invention is also characterized by the fact that it does not produce noise pollution since the use of an extremely silent electric motor.
