A handling apparatus moves drilling elements from and to a drill floor of a drilling rig includes a main support structure having a first end and a second end. An extendable ramp is between the first end of the main support structure and the drill floor. A carrier is movable relative to the main support structure and includes a first end close to the ramp and a second end distant from said ramp. A lift arm lifts and positions the carrier and includes a first end and a second end. The carrier moves between: a first position, in which the carrier is arranged above the main support structure; and a second position, in which the carrier is lifted at the level of the drill floor. The lift arm is under the carrier to move and support the second end of the carrier from and to the second position.

A collector circuit and associated circulation process, for intercepting and selectively diverting, at least partially, a fluid flow continuously flowing in a fluid circulation system, for drilling rigs. The collector includes a first sub-circuit with a first duct, with a first valve, and a second duct with a second valve; and; a second sub-circuit; The first sub-circuit, depending on the operating configurations of the first valve and the second valve, is adapted to allow the transit of the fluid flow in the first duct, and selectively divert fluid flow towards the second duct. The second sub-circuit is fluid-dynamically connected to the second duct of the first sub-circuit for receiving fluid flow, diverted by the first sub-circuit, and directing it towards a first outlet of the second sub-circuit. The second sub-circuit and the first sub-circuit are independent, and the second sub-circuit is removable from the collector circuit.

A mobile drilling rig () includes a mast (), a drilling head () for sliding in use along the mast (), and at least one hoist (). The drilling head () is supported by at least two hoisting wire cables (). The mast () is telescopic and includes a main load carrying member (), for extending the telescopic mast (), at whose end a plurality of pulleys () are provided, on which the hoisting wire cables () slide. The main load carrying member () is adapted to bring the mast () from a closed operating configuration to an extended operating configuration and vice versa. The movement of the drilling head (), when the mast () is in the extended operating configuration, takes place by the hoisting wire cables (), which are pulled and released by the at least one hoist ().

A method for automatic handling of drilling rods includes a step of handling at least one drilling rod () by a handler () designed for simultaneously clamping and moving the drilling rod (), and wherein the handler () moves the drilling rod () from an auxiliary retainer () to a main well (). The handling step takes place automatically and is controlled by a data processing unit, and includes automatic handling of a drill head () fitted with a chuck susceptible to being screwed to the drilling rod (); the automatic handling occurring among a plurality of heights (q-q) stored in the data processing unit.

Parking and automatic handling equipment of drilling rods () includes a carousel () of containers () of drilling rods (); and a rod handling system (), positioned on a drilling machine. A handling arm () transfers the drilling rods () out of the carousel (). The carousel () defines a closed path around which are arranged the containers () of drilling rods (); the carousel () includes an internal structure () for supporting the containers () movable on a closed path.

A reclosable mast () for drilling rig includes two opposed latticed structures (), constrained at one end to the base structure () placed in the drilling site 'P' and to each other, defining side faces () of the mast (). U-shaped structures, each include a rear bar (), adapted to get compressed when closing the mast (), and two side shoulders () parallel to each other and perpendicular to the an associated bar (). The U-shaped structures are arranged at preset intervals between the two latticed structures (), the rear bars defining the rear face or back () of the mast (). The mast () includes a diagonal members () located on the rear faceof the mast and constrained, between two superimposed U-shaped structures, the diagonal members () being adapted to split into at least two portions; reducing their longitudinal extension, and to allow reducing the dimension.

A draw-works () is for maneuvering drilling devices that includes a winder () for winding at least one rope (), which is centered on a shaft () having one first end and one second end and rotating in one first direction and in one second direction opposite to the first. The winder () is at least partially substantially cylindrical in shape. One or more supports () rotatably support the shaft (). Motors () are designed to enable rotation in the first direction and in the second direction of the shaft () and of the winder (). The supports () and the motors () are fixed to a frame base (). The motors () are set on both sides of the winder () and connect to them without speed-reducing elements, with direct drive on the shaft ().
