Definitions

  • the present invention refers to equipment for stowing and handling rods for use in drilling plants.
  • equipment for stowing and handling rods for use in drilling plants of well-known types comprises a drilling tower; a driving head supported by the tower itself; at least one container for the rods, and a control unit for moving the rods, which is suitable for receiving the rods from the container, and is also suitable for moving the rods themselves from a loading working position, in which the rods are horizontally arranged, and a vertical screwing position, in which the rods are vertically arranged do that they can be screwed onto the driving head.
  • the above mentioned lifting means comprises a beam for moving the rods which is frontally mounted to the drilling tower in order that it may rotate around a horizontal rotating axis, and a screwing device of the rods supported by the beam in order to block the rods in relation to the beam itself.
  • the equipment described above suffers from certain drawbacks due to the time needed to prepare the equipment itself, this relates in particular to the time necessary to prepare the equipment for working condition, which is very long.
  • Another drawback results from the fact that it is practically impossible to regulate the height of the rods in their vertical screwing working position unless the height of the entire control unit for moving the rods is regulated. This means, furthermore, that it is impossible to carry out screwing and/or unscrewing operations as far as the rods are concerned with the driving head at a height near to the handling plane.
  • the aim of the present invention is to realise equipment for stowing and handling rods for use in drilling plants, which does not only permit the resolution of the drawbacks described above in a simple and economic fashion, but also results in greater flexibility
  • equipment for the stowing and handling of rods for use in drilling plants comprising a service well for removing and placing individual rods, and a control unit for moving the rods suitable for moving the rods from and to the service well itself, and comprising tiltable means which can move between a flat working position and a raised working position in order to arrange the rods on an upright of the said service well, the equipment being characterised by the fact that the said tiltable means are preassembled tilting means which can be laterally installed to the service well, and comprise a support beam which can tilt around a rotating axis, and positioning means associated to the beam itself in order to position each individual rod in a set-up working position at least along the said upright.
  • the number 1 indicates a drilling plant, in its entirety, which is suitable for excavating boreholes (not illustrated).
  • the drilling plant 1 comprises a drilling tower 3 and a driving head 4 for the screwing of drilling rods 5 or casing pipes 5a ( Figures 4 and 5), and a quadrilateral articulated device, which is interposed between the tower 3 and the head 4, and is suitable not only for permitting the head 4 to slide along the tower 3, but also for permitting the movement of the head 4 itself from an operating working position, in which the head 4 is arranged on an upright A of the above-mentioned borehole, and a handling working position, in which the head 4 is arranged on an upright B of a service well 7 which is laterally arranged to the borehole itself.
  • the drilling plant 1 also comprises equipment 8 for stowing and handling the rods 5, which comprises in its turn a control unit 9 for moving the rods 5 themselves suitable for moving the rods 5 from and towards the service well 7, and for maintaining the rods 5 at a determined height in relation to the service well 7 itself, or for arranging the rods 5 inside the service well 7 in such a way that an operator can arranged the head 4 on the rod 5.
  • equipment 8 for stowing and handling the rods 5 which comprises in its turn a control unit 9 for moving the rods 5 themselves suitable for moving the rods 5 from and towards the service well 7, and for maintaining the rods 5 at a determined height in relation to the service well 7 itself, or for arranging the rods 5 inside the service well 7 in such a way that an operator can arranged the head 4 on the rod 5.
  • the equipment 8 also comprises two stowing stations S1 and S2 for stowing the rods arranged opposite the control unit 9 for housing the provisioning semitrailer 10 of the rods 5, and an unloading device 11 which is suitable for moving the rods 5 themselves from the provisioning semitrailer 10 to the control unit 9.
  • the equipment 8 can comprise two so-called "pipe racks" (noted but not illustrated), which can be arranged in the stations S1 and S2 in order to supply the control unit 9 with the rods 5.
  • the control unit 9 for moving the rods is a pre-assembled control unit, which can be transported using the usual means of transport, and can be installed laterally to the service well 7 between the two stations S1 and S2, and comprising a platform 12 presenting a main longitudinal axis C which is arranged incidentally and transversally to the uprights A and B, and a tiltable loader 13 which is rotatably mounted in relation to the platform 12 itself in order to rotate around a tilting axis D which is arranged transversally to the axis C, and is defined by a connecting hinge 14 of the loader 13 to the platform 12.
  • the loader 13 comprises a support beam 15 which is hinged to a base of the hinge 14, a carriage 16 which is slidingly mounted along the beam 15, two brackets 17 and 18 which define a longitudinal seat 19 parallel to the beam 15 itself, and a telescopic actuator device 20 connected to the beam 15 and to the platform 12 in order to rotate the beam 15 and the seat 19 between a flat working position, in which the seat 19 is arranged parallel to the C axis in order to receive a relative rod 5, and a raised working position, in which the seat 19 is arranged parallel to the B axis in order to arrange the rod 5 itself onto the upright B of the service well 7.
  • the carriage 16 is part of a positioning device 21, which is suitable for positioning the rods 5 in a set-up working position in order to permit the withdrawal of the driving head 4, and comprises, for each of the brackets 17 and 18, a pair of clamps 22 which can move from and towards the seat 19 in order to clamp onto a rod 5 arranged in the seat 19 itself.
  • the bracket 18 is a mobile bracket supported by the carriage 16, while the bracket 17 is a fixed bracket which is directly supported by the beam 15, and the respective clamps 22 present a clamping movement onto the seat 19 in order to prevent the rod 5 escaping from the seat 19 itself, and to permit the rod 5 to slide along the C axis by means of rollers (noted but not illustrated) on a axis which is transverse to the C axis itself.
  • control unit 9 comprises a stabilising and levelling device 23 which is suitable for stabilising and levelling the platform 12 in both a longitudinal and a transverse direction, which in its turn comprises four hydraulic hammers 24 arranged in correspondence to the respective corners of the platform 12 itself, and an adjusting screw 25 which is placed in front of the hinge 14.
  • the device 23 is suitable for co-operating with the unloading device 11 in order to permit a rod 5 to be coupled to the seat 19, said rod 5 having been unloaded from the provisioning semitrailer 10 by means of the unloading device 11 itself.
  • the unloading device 11 comprises, for each of the brackets 17 and 18, two telescopic vertical pipes 26 arranged opposite the respective brackets 17, 18, and a pipe 27, which is supported by the relative pipes 26.
  • the device 11 is provided with two blocking elements 28 arranged at the respective opposite ends in order to block in a waiting position the rods 5 provided from the stations S1, S2, and is also provided with two further blocking elements 29 arranged centrally to the pipe 27 itself in order to position a rod 5 onto the upright of the seat 19.
  • the pipes 27 are moved synchronously in relation to each other by means of activating the relative hydraulic or pneumatic pipes 26, and they are tilted from and towards the stations S1 and S2 of the pipes 26 themselves in order to assist the movement of the rods 5 from and towards the elements 29.
  • the unloading device 11 also comprises four stabilisers 30 for each provisioning semitrailer 10 itself in order to permit levelling in a longitudinal direction and tilting in a transverse direction in such a way as to assist the sliding of the rods 5 loaded onto the provisioning semitrailers 10 itself towards the elements 29.
  • the device 11 comprises a tilting device of a well-known type, which is not illustrated, suitable for assisting the sliding of the rods 5 loaded onto the "pipe rack" itself towards the elements 29.
  • Figures 4 and 5 refer to the situation in which casing pipes 5a, as well as rods 5, have to be moved, and illustrate an unloading device lls which comprises, for each station S1 and S2, two telescopic vertical pipes 26s and two horizontal pipes 27s installed on each provisioning semitrailers 10.
  • the head 4 for the rods 5 is replaced by a head 4a for the pipes 5a, and it can be seen from the illustration in Figure 4 that there are many advantages as a result of being able to work on the heads 4 and 4a at a height equal to the handling height when faced with the necessity of hooking the rods 5 and the pipes 5a.
  • the platform 12 is taken to the excavation site by means of normal, well-known types of means of transport, and once the platform 12 has been laterally positioned to the service well 7 with the relative C axis orientated transversally to the uprights A and B, the two stations S1 and S2 are engaged by one or two provisioning semitrailer 10, which, as illustrated in Figure 2, move and/or stow the drilling rods 5 or, alternatively, casing pipes of a well-known type which are not illustrated.
  • the unloading device 11 positions the pipes 27 at a height which substantially corresponds to the height of the upper edge of the side panel of one of the two provisioning semitrailer 10, while the stabilisers 30, after having levelled each provisioning semitrailer 10, tilt the provisioning semitrailer 10 itself from the side of the control unit 9 in order to send the relative rods 5 to abut against the blocking elements 28.
  • the pipes 27 are tilted to permit the rod 5 itself to slide towards the elements 28: thus, the elements 29 are disengaged from the rod 5, which rolls towards the elements 28 themselves and is blocked by coming into contact with the elements 28 themselves, and when the rod 5 is positioned on the upright of the C axis, which is to say directly above the seat 19, the pipes 27 are lowered to a point where the rod 5 itself can be inserted inside the seat 19.
  • the clamps 22 block the rod 5 in the seat 19 in such a way as to prevent any movement of the rod 5 itself in relation to the seat 19 itself, and, subsequently, the telescopic actuator device 20 rotates the beam 15 around the hinge 14 in such a way as to arrange the rod 5 itself in its set-up position, which corresponds to a position in which a lower end 31 of the rod 5 itself remains substantially outside the service well7, which an upper end 32 of the rod 5 is directly screwed onto the head 4.
  • the clamps 22 free the rod 5 itself, and, while the quadrilateral articulated device 6 moves the head 4 and the rod 5 onto the upright A, the device 21 moves the seat 19 back to its flat working position.
  • the carriage 16 is made to slide together with the relative bracket 18 in relation to the beam 15, while the rod 5, which is firmly blocked by the clamp 22 of the bracket 17, slides inside the bracket 17 by means of the above-mentioned rollers (noted but not illustrated) on an axis transverse to the C axis.
  • the positioning height of the rods 5 along the C axis can be freely regulated by simply moving the carriage 16 in relation to the beam 15, and by maintaining the rod itself firmly inside the bracket 18.
  • each rod 5 is substantially controlled starting from the provisioning semitrailers until it reaches its set-up position it is practically impossible for the rod 5 itself to move accidentally and create a danger to the operators working on the drilling plant 1.
