Definitions

  • the present invention concerns a drilling machine which can be used to prepare excavations to make tunnels.
  • the machine according to the invention can be used to make holes and drillings in tunnels and to consolidate excavations, for example by injecting filling and anchoring materials into the holes.
  • Drilling machines generally of the horizontal type, are known, used to prepare excavations in tunnels, able to make holes in a substantially horizontal direction in the walls to be excavated, and possibly inject filling and anchoring materials in them to consolidate the walls.
  • drilling machines are generally provided with a drilling unit comprising a mast, or guide beam, on which a rotating head is mounted, sliding in a longitudinal direction, with which the drilling member is rotated to make the holes.
  • the mast is connected to a fifth wheel positioning device, that is, a gear that allows a rotation of about 180° around a horizontal axis of rotation, and is made to rotate on each occasion so as to make holes disposed radially with respect to the drilling machine itself.
  • a fifth wheel positioning device that is, a gear that allows a rotation of about 180° around a horizontal axis of rotation, and is made to rotate on each occasion so as to make holes disposed radially with respect to the drilling machine itself.
  • the fifth wheel is pivoted at one end to the mast, and at the opposite end to the frame of the drilling machine and its rotation around the axis of rotation selectively makes the mast move along a circumference arc, with its longitudinal axis disposed in a substantially horizontal direction.
  • Drilling machines which provide the fifth wheel pivoted in correspondence with one of its central points to the frame, and connected on one side and the other to a respective mast, so as to simultaneously position two drilling members.
  • the fifth wheel positioning device although it allows to make holes disposed in a radial pattern, has some disadvantages.
  • a first disadvantage is that the fifth wheel has few degrees of freedom, and only allows to rotate the mast and not to position it in a lateral direction. In order to correctly align the mast with the excavation front, it is therefore necessary to correctly position the drilling machine with respect thereto, as it is not possible to correct any possible misalignments with the fifth wheel device.
  • Another disadvantage of fifth wheel devices is the fact that, in order to make holes on circumferences with different radiuses, it is necessary to move the drilling machine itself, or to replace one or more components, causing downtimes and delay in the work.
  • Another disadvantage is that, although they allow to easily make the holes on a circumference which extends above the drilling machine, fifth wheel devices do not allow to make the holes equally well in a frontal position to the machine.
  • the fifth wheel does not allow to lower the mast frontally, keeping it substantially parallel to the ground, in order to position the drilling member effectively, therefore the holes in the frontal direction are generally made with an inclination accentuated downward instead of substantially horizontal.
  • Another disadvantage of the solutions that provide to use a fifth wheel is also that they are not very versatile and robust; if the fifth wheel malfunctions or breaks, in particular, it is necessary to interrupt operations and carry out the maintenance or replacements required to continue the work.
  • DE-A-28 36 659 describes a multi-use drilling machine for the mining industry comprising a vehicle mounted on tracks with a vertical structure in the front part which supports an elbow-shaped arm on which multi-function tools are installed.
  • the elbow-shaped arm can rotate completely around a horizontal axis and carries actuator cylinders to drive extended tie rods which in turn carry additional cylinders for other arms and the tools themselves.
  • WO-A-03/031764 describes a drilling machine comprising a frame mobile with respect to the ground, an arm of the tool, a drilling tool operatively mounted on the arm of the tool and defining a drilling end and an actuator of the arm of the tool which can be selectively driven, and which connects the arm of the tool to the frame.
  • the support of the arm of the tool comprises five actuators that respectively allow a rotation of the arm of the tool around a vertical axis, a translation along a first horizontal axis, a translation along a second horizontal axis perpendicular to the first horizontal axis, a rotational displacement on a third horizontal axis, and a rotatable displacement around a fourth horizontal axis.
  • One purpose of the present invention is to produce a drilling machine which overcomes at least some of the disadvantages of the state of the art.
  • One purpose of the present invention is to produce a drilling machine, in particular to prepare excavations in tunnels, which allows the precise positioning of the mast and of the drilling member.
  • Another purpose of the present invention is to provide a drilling machine which requires lower power and energy consumption than machines known in the state of the art.
  • Another purpose of the present invention is to provide a drilling machine which allows to make in a horizontal direction both holes on circumferences with a larger radius, as well as holes on circumferences with a smaller radius in a frontal zone of the drilling machine itself.
  • Another purpose of the present invention is to provide a drilling machine to prepare excavations in tunnels which allows to position on each occasion the mast and the drilling member in a suitable position without the need to move the drilling machine, thus reducing the work time required to perform operations.
  • Another purpose of the present invention is to produce a drilling machine which is versatile and can also be used, with simple modifications, to make drilling holes in a vertical direction.
  • Another purpose of the present invention is to produce a drilling machine that is robust and efficient even if some components malfunction.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a drilling machine comprises, in a known manner, a movement unit to move it, a work member suitable to perform one or more operations, such as for example drilling, and support members suitable to support and position the work member, for example a drilling member, and/or devices to inject consolidation material.
  • the support members comprise a support rod, defined as mast in the specific field, and a rotating head slidable along the mast and to which the work member is connected.
  • the drilling machine comprises a first positioning unit provided with an articulation device configured to allow the rotation of the mast on a vertical plane around a first horizontal axis of rotation.
  • the drilling machine comprises a second positioning unit connected between the first positioning unit and the mast and configured to allow other movements of the mast with respect to the first positioning unit.
  • the second positioning unit comprises an oblong support element, connected to the articulation device of the first positioning unit and provided with a support surface for the mast.
  • the second positioning unit also comprises positioning means cooperating with the oblong support element and each suitable to confer at least one degree of freedom to the mast with respect to the support element.
  • the drilling machine comprises a swivel actuator connected between the frame and the first positioning unit, and configured to allow a swivel movement of the first positioning unit, and of the components connected thereto.
  • the second positioning unit is connected to the mast by means of a rotational joint and comprises vertical rotation actuator means suitable to allow a rotation of the mast around a first vertical axis with respect to the support surface.
  • the support surface is inclined with respect to the wall of the support element connected to the positioning unit. This inclination allows to reach more positioning angles of the mast with respect to the horizontal plane, so as to be able to reach all the positions necessary to make the holes to prepare the excavations.
  • the second positioning unit comprises horizontal sliding actuator means configured to move the mast in a linear and planar direction with respect to the support surface.
  • the first positioning unit comprises a fixed body and a body rotatable with respect to the fixed body around the first horizontal axis and horizontal rotation actuator means comprising a pair of linear actuators acting in opposite directions on opposite sides of the fixed body with respect to the first horizontal axis, so as to allow a continuous rotation movement of the rotatable body, and therefore of the mast, along a circumference arc.
  • This solution allows to reduce the overall weight of the positioning unit with respect to the fifth wheel device, and consequently obtain a reduction in energy consumption.
  • Embodiments described here also concern a method to position the mast of a drilling machine with respect to an excavation front to make holes in a tunnel.
  • the method according to the invention provides to position the drilling machine in correspondence with an area to be subjected to drilling, and to move the mast on a vertical plane, around a first horizontal axis of rotation by means of a first positioning unit provided with an articulation device.
  • the positioning method also provides to move the mast with respect to the first positioning unit by means of a second positioning unit.
  • the method provides to support the mast with an oblong support element connected to the articulation device and to drive positioning means cooperating with the oblong support element to move the mast with respect thereto.
  • the method provides to swivel the first positioning unit, and with it the second positioning unit and the mast, on a horizontal plane, around a vertical axis of rotation lying on the longitudinal median plane of the drilling machine by means of a swivel linear actuator connected between the frame and the articulation device, so as to allow a correct positioning of the mast with respect to the excavation front even in the case where the drilling machine is not aligned with it.
  • the method provides to rotate the mast around the first horizontal axis of rotation by means of an articulated device, by rotating a rotatable body of the latter with respect to a fixed body thereof by means of horizontal rotation actuator means comprising a pair of linear actuators acting in opposition to each other on opposite sides of the horizontal axis of rotation.
