Definitions

  • the present invention relates to a machine for drilling and boring, in particular a crawler crane provided with a jib configured for supporting a guide mast for excavation equipment.
  • Said machines which are generally used for making holes of a diameter of up to 1500 mm and a depth of up to approximately 30 m in a single operation, generally have large dimensions and must be dismantled to be transported on the road by appropriate road trucks.
  • the jib, the ballast, and the crawler tracks of the crane are dismantled from the basic machine and transported separately from the latter.
  • the guide mast is dismantled into a plurality of elements and is also transported separately on a respective truck.
  • the steps for assembly of the guide mast are instead particularly long and laborious.
  • the various elements of the mast must be arranged properly aligned on a series of resting trestles to be connected together and fixed by means of screws and/or bolts. Alignment is particularly complex and problematical in the case where the trestles are to be positioned on rough or irregular terrain.
  • Both of the steps imply a plurality of operations, which must be carried out in part manually by operators and are physically demanding, tiring, and dangerous for the physical safety of the operators.
  • One purpose of the present invention is to improve the machines for drilling and boring described above, in particular increasing the versatility and flexibility of use thereof.
  • Another purpose is to obtain a machine for drilling that is convenient and fast to set up and equip so as to reduce significantly the times required for its assembly/disassembly, with consequent reduction in the management costs.
  • a further purpose is to obtain a machine, assembly and disassembly of which will require a reduced number of manual operations, that will not be too physically demanding for the operators and will involve a low degree of danger for them.
  • Yet another purpose is to provide a machine that, once dismantled, will present compact dimensions and limited encumbrance so as to enable convenient transportation on the road.
  • Yet a further purpose is to obtain a machine that has a compact and sturdy structure, will be safe and reliable in operation, and will enable the guide mast to be placed in a vertical and/or inclined operating position in a precise and accurate way.
  • a machine for drilling comprising undercarriage means, which rotatably support jib means, to which there can be removably associated, in an assembled condition of said machine, supporting and guide mast means for excavating devices, said machine being characterized in that said mast means comprise a plurality of elongated elements, which can be interconnected and are mobile in such a way as to enable arrangement of said mast means selectively in an extended position and in a folded position.
  • the mast means comprise elements that are interconnected, for example hinged, to one another, they can be folded and extended rapidly and conveniently without the need to carry out delicate and laborious procedures of positioning and alignment.
  • the procedures of assembly and disassembly are further simplified and speeded up by the presence of movement means, which, being positioned within the elements themselves, displace the aforesaid elements between the two different positions in an automatic way, without any need for manual intervention on the part of operators. In this way, it is possible to reduce the number of manual operations normally necessary for assembly/disassembly of the mast, which entail for the operators considerable physical effort and constitute a working hazard.
  • the machine according to the invention in the dismantled condition moreover has dimensions and encumbrance that are particularly compact and limited so as to enable convenient transportation on the road.
  • a machine for drilling comprising undercarriage means, which rotatably support jib means, to which there can be removably associated, in an assembled condition of said machine, and supporting and guide mast means for excavating devices, said machine being characterized in that it comprises top end-guide means designed to support and guide rope means for hoisting said excavation devices, said end-guide means being connected in a removable way to said mast means.
  • the end-guide means are removably connected to the mast means, they can in fact be easily and rapidly dismantled from the latter and possibly fixed to engagement means, provided on the jib means. In this way, even dismantling and separating the mast means during transportation of the machine, it is not necessary to disengage from pulley means the end-guide means and from block means the rope means, which can thus remain entrained over the sheaves a number of times. This fact leads to a considerable saving in time both in the assembly step and in the step of disassembly of the machine and makes it possible to avoid a plurality of manual operations that are particularly tiring and hazardous for operators.
  • a machine for drilling 1 which comprises an undercarriage 2, rotatably mounted on which is a jib 3 designed to support a guide and supporting mast 10 for drilling and boring devices 40 of a known type.
  • the mast 10 which is removably fixed to the jib 3, in turn supports end-guide means 8 designed to receive and guide hoisting ropes 4 for the drilling and boring devices 40.
  • the undercarriage 2 is provided with dismantlable crawler tracks 25 and houses actuation means 20 designed to move the jib 3, and winch means 28 arranged for operating the hoisting ropes 4.
  • ballast 30 Removably fixed to a portion of the undercarriage 2 opposite to the one to which the jib 3 is connected is a ballast 30.
  • the jib 3 comprises a box-section structure that is substantially made up of three box-type beams or longitudinal members joined together to form a triangle.
  • the jib 3 consequently presents a first end 3a hinged to the undercarriage 2, a second end 3b connected to actuation means 20, and a third end 3c, which can be rotatably coupled to said mast 10.
  • the overall dimensions of the jib 3 are such as to enable transportation thereof on the road without any need to take it down from the undercarriage 2.
  • the box-section structure of the jib 3 in addition to enabling reduction in the overall dimensions, offers, as compared to lattice jibs of a known type, a higher strength in regard to torsional stresses that are generated during operation of the drilling and boring devices.
  • the means 20 for actuation of the jib 3 comprise respective motor means 21, designed to move by means of further ropes 22 rod means 23, hinged at a first end 23a to the undercarriage 2 and connected at the remaining second end 23b to the second end 3b of the jib 3 by tie-rod means 24.
  • the machine 1 further comprises first strut means 6 and second strut means 7, designed to connect said jib 3 to the mast 10 and to the undercarriage 2, respectively.
  • the first strut means 6 comprise a pair of first struts 6a, 6b that can be telescopically lengthened and are rotatably connected to first means 15 for attachment of the mast 10 and to respective joining plates 14a, 14b, fixed to opposite sides of the second end 3b of the jib 3.
  • the second strut means 7 comprise a pair of second struts 7a, 7b, which can also be telescopically lengthened and are fixed, at one respective end, to means 26 for connection of the undercarriage 2, and at the remaining end, to said joining plates 14a, 14b.
  • Each strut 6a, 6b, 7a, 7b includes a linear oleodynamic actuator, which is able to lengthen/shorten the strut itself by a limited amount in order to correct and adjust the position of the mast 10 in an assembled condition of the machine 1, as will be described in greater detail in the description of operation of the latter.
  • telescopic struts 6a, 6b, 7a, 7b in association with the box-section jib 3, in addition to enabling an extremely sturdy and compact structure, makes it possible to perform, as compared to traditional machines, a larger variety of movements for setting the mast 10 in a vertical or inclined operating position for compensating for any possible irregularities of the terrain on which the machine moves.
  • the mast 10 comprises a plurality of elongated elements, for example a first, central, element 11, a second, top, element 12, and a third, bottom, element 13, which are hinged to one another at the ends in such a way as to enable the mast 10 to be folded or extended in a folded position F and an extended position E.
  • the second element 12 and the third element 13 are rotatably mounted on opposite ends of the first element 11 about respective parallel axes X1, X2 in such a way as to rotate through approximately 180°, in the same plane as a longitudinal reference plane of the mast 10.
  • the length of the first element 11 is slightly greater than the lengths of the second element 12 and the third element 13 to enable folding through 180° of the latter elements on one and the same side of the first element 11.
  • the aligned elements 11, 12, 13 are clamped with respect to one another by means of threaded connections, for example bolts or screws.
  • the elongated elements 11, 12, 13 are, for example, rectilinear hollow beams with rectangular or square cross section.
  • the mast 10 comprises movement means 17, positioned inside the elements 11, 12, 13 and arranged for rotating the second element 12 and the third element 13 from the folded position F to the extended position E, and vice versa.
  • the movement means 17 comprise oleodynamic means and lever mechanisms, of a known type and not illustrated in detail in the figures.
  • the second element 12 and the third element 13 can be slidably connected to the first element 11 by means of purposely provided guide and supporting means, in such a way as to change from the folded position F to the extended position E and vice versa, not via rotation but via two distinct and successive mutually orthogonal movements of translation.
  • the second element 12 and the third element 13 can slide axially in sequence in a first direction and in a second direction parallel and orthogonal, respectively, to a longitudinal axis of the first element 11.
  • Second attachment means 16 Fixed to the first central element 11, in addition to the first attachment means 15, are second attachment means 16 for removable coupling to the third end 3c of the jib 3.
  • end-guide means 8 comprising sheave means 18, around which the lengths of rope 4 are wound a number of times for raising the block means 19.
  • the end-guide means 8 comprise an approximately T-shaped body 27, mounted transversely on a free end of the second element 12 of the mast 10 and the opposed arms of which support a plurality of sheaves 18 mounted idle.
  • a resting element 14 Removably fixed to a respective free end 13a of the third element 13 is a resting element 14, referred to as mast foot, by means of which the mast 10 in the assembled and upright configuration A of the machine 1 rests on the ground ( Figure 6 ).
  • the machine for drilling 1 is illustrated in a dismantled configuration B in which the mast 10 is disconnected from the jib 3 and set in the folded position F, whilst the undercarriage 2 is without the tracks 25 and has the jib 3 bent forwards and in an extended position.
  • the end-guide means 8 are engaged to the jib 3.
  • the mast 10 and the undercarriage 2 can be conveniently loaded and transported by respective road trucks.
  • the jib 3 comprises appropriate engagement means designed to support the end-guide means 8, with the corresponding block means 19, once these are disconnected from the mast 10.
  • the engagement means are provided on a side wall of the jib 3, in a position corresponding to the joining plate 14a.
  • the first strut means 6 will remain associated to the mast 10 and disconnected from the jib 3, the second strut means 7 remaining connected to the jib 3 and to the undercarriage 2.
  • the mast 10 is laid on a pair of trestles or supports, set at a distance such as to be able to support the first element 11 of the mast.
  • the undercarriage 2 is hence positioned with respect to the mast 10 in such a way that the jib 3 can be connected to the second attachment means 16 of the first element 12 and the first two struts 6a, 6b can be raised and connected to the joining plates 14a, 14b of the jib 3 ( Figure 4 ).
  • the mast can be pulled out into the extended position E in an automatic way by actuating the movement means 17 inside the elements 11, 12, and 13.
  • the movement means 17 are connected, for example, to an external supply circuit provided with an oleodynamic pump.
  • the mast 10 can be opened into the extended position E before being fixed to the jib 3 to enable use of the latter to carry out some subsequent assembly steps, for example, the subsequent connection of the end-guide means 8 to the mast 10.
  • the end-guide means 8 are disengaged from the means for engagement of the jib 3 and laid on the ground and are then raised and fixed to the free end 12a of the second element 12 ( Figure 5 ). To do this, it is necessary to unwind the ropes 4 partially from the winch means 28.
  • the machine 1 is assembled, and it is possible to raise the mast 10 into the vertical operative position, by actuating the actuation means 20 that act on the jib 3.
  • the second struts 7a, 7b are free to be shortened telescopically.
  • the telescopic parts of the second struts 7a, 7b are fixed to one another, and only minor corrections in length of the struts are allowed by means of the oleodynamic actuators associated thereto in order to adjust the position of the mast 10 precisely.
  • the machine 1 is ready for receiving a drilling device 40 fixed and supported by the block means 19 and constrained to the resting element 14 ( Figure 6 ).
  • the procedure of disassembly basically comprises the same steps as those of the assembly procedure in reverse order.
