Definitions

  • the present invention refers to a mobile drilling unit.
  • Mobile drilling units of a well-known type comprise a means of transport, a drilling tower which is mounted in such a way as to be able to revolve around a horizontal rotation axis, a tilting device which is hinged to the means of transport in order to position the tower between a position for transport, in which the tower lies flat on the means of transport, and a working position, in which the tower is arranged vertically, and a motor head, which is mounted in such a way as to be able to slide along the tower, and which is suitable for carrying out drilling in the ground by means of drilling rods.
  • a container which is used for storing and manoeuvring the rods, and which is suitable for supplying the drilling rods to the motor head during the drilling operation and for freeing the motor head itself during the extraction of the rods.
  • U5-3,741,322 discloses a drilling rig carried by a catterpillar truck and comprising a mast with a drilling carriage and a drilling roll magazine disposed on the mast.
  • the aim of the present invention is to produce a mobile drilling unit, which is, at the same time, extremely flexible and easy to set up, and which presents a high degree of autonomy in terms of drilling.
  • a mobile drilling unit comprising a means of transport, a drilling tower, which is supported by the means of transport and which is revolvingly mounted around a horizontal rotation axis, tilting means which are used for tilting the tower from and to a flat position for transport, a motor head which is assembled so as to slide along the tower, and which is suitable for carrying out drilling by means of a determined number of drilling rods and a container for storing and manoeuvring said drilling rods which is associated with the drilling tower and which is mounted on said tilting means; the unit being characterised by the fact that the tilting means comprise a first support for the drilling tower and a second support for the container, the first and second supports being hinged to the means of transport in order to rotate independently from each other around the respective rotation axes which are parallel to each other.
  • the number 1 indicates a mobile drilling unit in its entirety which is suitable for carrying out drilling in the ground by means of a determined number of drilling rods 2.
  • the unit 1 comprises a means of transport e which is provided with a transport platform 4, a drilling tower 5 which is supported by the platform 4 and which is revolvingly mounted in relation to the platform 4 itself so that it can rotate around a horizontal rotation axis A1, and a motor head 6 which is supported by the tower 5 and which is suitable for sliding along the tower 5 itself in a direction D1 for drilling by means of the interposition of a trolley 7 which is slidingly coupled to the tower 5.
  • the unit 1 also comprises a tilting device 8 which is mounted on the platform 4 in correspondence with a rear edge 9 of the platform 4 itself and which is transverse to the direction D1, and which is suitable for tilting the tower 5 between a working position for transport, in which the tower lies flat on the platform 4, and a working position for drilling, in which the tower 5 is raised into a vertical position above the edge 9.
  • a tilting device 8 which is mounted on the platform 4 in correspondence with a rear edge 9 of the platform 4 itself and which is transverse to the direction D1, and which is suitable for tilting the tower 5 between a working position for transport, in which the tower lies flat on the platform 4, and a working position for drilling, in which the tower 5 is raised into a vertical position above the edge 9.
  • the unit 1 comprises a container 10 for storing and manoeuvring the rods 2 which is associated with the tower 5 and which is mounted on the tiling device 8 in order to follow the tower 5 between the 2 working positions described.
  • the tilting device 8 comprises a support 11 for the tower 5, a support 12 for the container 10 and, for each support 11 and 12, a pneumatic activating device 13 which is suitable for endowing the relevant support 11, 12 with a rotation which is independent of the rotation of the other support 12, 11.
  • the support 12 is substantially L-shaped and presents a base 14 which is hinged to the platform 4 in correspondence to an axis A2 which is parallel to the axis A1, and a handling side frame 15 which is integral to the base 14 itself, and which is connected to the relative device 13.
  • the support 11, instead, comprises a handling arm 16 which is hinged to the platform 4 and which is connected to the tower 5 on the part of the tower 5 which is opposite the part which is suitable for the trolley 7 to slide along.
  • the container 10 comprises a frame 17 which is slidingly mounted on the base 14 of the support 12, and which presents a number of hackled compartments 18 which are arranged in series one after the other in a sliding direction D3 which is determined by the base 13 and which is transverse to the drilling direction D1.
  • Each compartment 18 is suitable for containing at least four drillings rods 2, and presents an upper opening 19 for the upper section of the rods 2 to emerge, and a side opening 20 which faces the tower 5 for the total emergence of the rods 2.
  • the trolley 7 comprises a handling device 21, which is associated with the motor head 6 in order to move the motor head 6 itself parallel to itself from and to a pick-up position in correspondence with the top of the container 10, and comprising a prismatic telescopic guide 22 which can be elongated in a direction D2 of elongation which is transverse to the drilling direction D1 and the direction D2 in which the container 10 itself slides.
  • the mobile drilling unit 1 When in use, the mobile drilling unit 1 is positioned with its own edge 9 in correspondence with the site where the drilling is to be carried out, and with the tower 5 and the container 10 arranged in their respective working configurations for transport, which means that they are flat in a horizontal position above the platform 4.
  • the motor head 6 is raised to the top of the tower 5 by a raising device 23, and from there it is translated parallel to itself on the vertical to a rod 2 which is contained in one of the compartments 18.
  • the rod 2 When the rod 2 has been hooked to the motor head 6, the latter is once again translated in the direction D2 until it is vertical to the site where the drilling is to be carried out, and the pick-up movement is executed every time it is necessary to introduce a new rod 2 into the drilling site itself.
  • the elongation of the guide 22 depends on the position occupied by the rod 2 which is to be picked up from the inside of the relevant compartment 18, and once a compartment 18 has been completely emptied, the frame 17 is moved in the direction D2 along the arm 14 in such a way as to present a new compartment 18 which is full of rods 2.
  • the sliding, parallel to itself, of the rotation axis of the motor head 6 determines a working plan, which is parallel to the directions D1 and D2 and which is transverse to the direction D3, and which is suitable for defining the position of each compartment 18.
  • the container 10 is refilled by means of carrying out the above-described operations in reverse order.
  • the unit 1 lends itself to the prompt and rapid preparation and dismantling of a drilling site and that, furthermore, the capacity of the container 10 results in a high level of operating autonomy.
