A drilling machine includes a loading device of the carousel type for a plurality of rod modules and optionally a plurality of covering modules. The loading device includes a platform, on which the rod modules are arranged to be orthogonal to the platform, and a conveyor system for conveying the rod modules along a closed path. The carousel loading device includes a lateral containment frame provided with an opening for the extraction and/or insertion of the rod modules through the translation of the rod modules in a direction that is substantially parallel to the platform or has at least one component parallel to the platform.

A drilling machine includes a self-propelled motor vehicle, a front drilling member, and a rear drilling member, wherein at least one of the front or rear drilling members has at least one drilling head suited to be oriented in any direction with respect to the advance direction of the machine, and wherein at least one of the front or rear drilling members has an integrated sliding system suited to stabilize the member on the ground.

Drilling machine

A drilling machine, particularly for use in non-rocky terrain, includes a machine body with a mast equipped with one or more rotary operating heads having chucks coupled thereto for the downward rotation of drill stem modules and/or shroud tube modules, and a carousel loader of the drill stem modules. Each of the drill stem modules is inserted in a shroud tube module and is carried on a sliding platform. The drilling machine further includes a loader having a plurality of rods, forks, sockets, or seats, suitable for inducing a forward transfer of the shroud tube modules and corresponding drill stem modules in a substantially vertical position.

A boring head system for boring machines includes couplings or drive units for the rotation-translation of at least one boring rod and of at least one covering tube that are coaxial and hollow, such to allow the passage of pressurized water/air as well as the upward flow of waste fluid consisting of water/air mixed with debris along the interspace defined between the rod and the covering tube, and also includes a protection screen or wall completely enveloping the rod and the covering tube, suited to be positioned near or at the level of an upper annular opening of the interspace, out of which the waste fluid flows, in such as way as to intercept the waste fluid in all directions and to convey it downwards.

The invention is a new well drilling machine, in particular for drilling with single pipes, with supporting mast (M) provided with at least one drill head' (R) for the rotation-translation movement of the drill pipe (A), a loader (C) for said pipes (A), hinged to the relative supporting frame (T), integral with the machine body, and wherein said loader (C) can be slanted from the non-operating position () to the operating position (), in which said pipes (A) are further slanted with respect to ground level, and vice versa. The loader (C) comprises sliders (J, K) which run on parallel guides (S) and on which said pipes (A) rest transversally, wherein two or more long pins or bars (P) square to and integral with said sliders (J, .K) are positioned between adjacent pipes (A), and wherein the running of said sliders (J, K) causes the translation of said bars (P) and said pipes (A).

A mobile basket for consolidation work on walls is provided with a main frame, configured in the front part for hoisting and for translating the new basket up and down a wall and having legs fitted on the sides of said main frame. A secondary frame or cage is structured for supporting a magazine of drill rods, as well as a mast or drill and a mechanical hand applied to the secondary frame or cage positions parallel to its longer side and essentially perpendicular to the main frame. The mechanical hand, positioned between the mast or drill and the magazine, is configured to take a rod from the magazine and transfer it to the mast or drill.

Mobile basket for consolidation work on walls

A drill head for drilling machines having a protective screen for conveying the drilling slurry discharged from the drivers drill rods and related sleeves. A screen constructed according to the principles of the present invention reduces the slurry fallout area in the vicinity of the drilling zone. The screen panel has a generically U-shaped cross section, or in any case such a cross section as to cover wholly or partly at least three sides around the area where the slurry is discharged from the drivers of the drill rod (A) and related sleeve. In one embodiment, the screen panel is coupled to the structure of the drill head by connection supports and translation devices, so to translate the screen panel parallel to the rod and the sleeve.

Drilling head with protective screen

The invention is a new drill for making micropiles, equipped with a mast on which the head-carrying trolley slides and having at the bottom of the mast two pairs of vices, a lower fixed vice and a upper unscrewing vice. Besides being able to rotate around the drilling axis, the unscrewing vice is able to move along said mast with respect to the lower fixed vice. The advantages are considerable, since it is no longer necessary to dismantle the rod and the covering during the extraction stages.
