Definitions

  • the invention concerns an introduction assembly for reinforcement rods in drilling machines advantageously but not exclusively employed to prepare excavations to make tunnels.
  • the invention is employed in machines used to make consolidation work in excavations of tunnels by making holes in the wall to be excavated, inside which holes suitable consolidation elements, also known as reinforcement rods, are inserted.
  • the state of the art includes drilling machines used to prepare excavations for tunnels and able to make substantially horizontal holes in the wall which has to excavated, and to introduce consolidation elements, also known as reinforcement rods.
  • Such drilling machines are provided with one or two drilling assemblies, each comprising a mast, or guide beam, on which one or more rotary heads are mounted sliding longitudinally; by means of said heads the drilling instrument, generally consisting of rod elements, is made to rotate to penetrate into the ground.
  • Each mast is also provided with guide elements suitable to keep the drill tool on its axis, and vice means able to allow the tool to be assembled and dis-assembled.
  • the masts are mounted by means of articulated joints provided for this purpose on telescopic columns attached to rotary plates and therefore able to assume a different extension and a different inclination according to the position where the holes have to be made.
  • the reinforcement rods are inserted into the ready prepared holes by means of introduction assemblies with which the drilling machines are provided and which in general are associated with the masts supporting the rotary head of the drilling tools.
  • the masts are therefore extremely heavy and cumbersome, with considerable limits in terms of movement and functionality.
  • the working assemblies cannot cross over with respect to each other and therefore the drilling assembly has to stay always on one side of the introduction assembly and vice versa.
  • the purpose of the invention is to achieve an introduction assembly for reinforcement rods for drilling machines which can operate simultaneously with the mating drilling assembly, without interfering with the latter, irrespective of its position, thus allowing to optimize the working cycle of the drilling machine on which it is installed.
  • Another purpose is to achieve an introduction assembly for reinforcement rods which, in its movement of rotation, can cross over with the mating drilling assembly, so as to be able to operate substantially inside the whole area to be drilled.
  • the introduction assembly for reinforcement rods comprises a mast, or guide beam, of the folding type able to assume at least an extended working configuration, and a folded for movement configuration in which it is able to move from one side to the other of the drilling assembly of the drilling machine, allowing a mating movement of the introduction assembly.
  • the mast is associated with a pair of supporting shafts of the telescopic type mounted on rotary means able to make it perform an angular excursion such as to cover the whole area to be drilled, in order to selectively arrange the introduction assembly between two positions in proximity with the ground arranged on opposite sides with respect to the drilling machine.
  • the mast In its folded for movement configuration, the mast is able to be contained longitudinally in the space defined by the column-type supporting elements of the drilling assembly so that, by means of the relative shaft elements and the rotary means on which these are mounted, the introduction assembly can pass below the drilling assembly and position itself on the opposite side to that where it was initially operating.
  • the mast comprises a plurality of segments, connected to each other by means of hinge elements, which in the extended working configuration are aligned longitudinally and in the folded for movement configuration are arranged substantially adjacent to each other.
  • the segments are folded and extended by actuator means connected to the segments by lever means.
  • a toothed profile is associated with the mast and mobile trolleys are engaged thereon, supporting centering and/or rotation means for said reinforcement rods and/or supporting and winding means for the hydraulic equipment of the drilling machine.
  • the mobile trolleys with the relative means which they support, are able to be moved to allow the correct folding of the mast.
  • the introduction assembly according to the invention is therefore able to be moved from one side to the other of the mating drilling assembly and is therefore able to operate, without interfering with the latter, over the whole area to be drilled.
  • a drilling machine 20 provided with the introduction assembly 10 for reinforcement rods according to the invention is able to be used to prepare excavations to make tunnels.
  • the drilling machine 20 comprises a frame 11 mounted on a truck 12 with tracks and provided with four, hydraulically driven stabilizer rods 13 able to rest on the ground to prevent the truck 12 from moving when the drilling machine 20 is operating.
  • the frame 11 extends in two extensions 14, each of which is provided with a relative support 15.
  • respective rotary plates 16 are mounted, with a horizontal axis of rotation "x" substantially aligned and lying on the longitudinal median plane "Z" of the drilling machine 10.
  • Two relative columns 17, of the telescopic type and independently driven, are associated with the two rotary plates 16. They are able to perform an angular excursion ⁇ such as to cover the whole area to be drilled (Fig. 4).
  • Each rotary plate 16 is mounted on a respective slider 34 able to slide on a vertical guide stanchion 25 arranged in a position inside the columns 17 on the longitudinal median plane "Z" of the drilling machine 20.
  • the columns 17 support a drilling assembly 30 comprising a mast, or guide beam, 18 along which a rotary head 19 is mounted sliding on a trolley 21 and able to make the tools or drilling rods 33 rotate.
  • the mast 18 is associated with the relative columns 17 by means of articulated joints 22 which allow it to be possibly inclined in order to achieve non-horizontal holes.
  • the system defined by the two cylinders 42 and 43 and by the guide elements 40 and 41 not only allows a uniform distribution of the stresses of the drilling assembly 30 on the two columns 17, but also it allows to vary the inclination of the mast 18 and the amplitude of the angles between the columns 17 when such conditions become necessary to make the holes, without danger of breakages and/or damage to the drilling assembly 30.
  • a centering trolley 23, able to keep the drilling rods 33 in position, is also mounted on the mast 18, and also two vices 24 which permit to mount and remove the drill rods 33 during the working cycle.
  • Each extension 14 also supports a respective motorized rotary plate 26 with a horizontal axis of rotation "y" parallel to the axis "x".
  • a telescopic shaft 27 is mounted, able to make an angular excursion ⁇ , according to the rotation of the respective rotary plate 26, so as to cover the whole area to be drilled (Fig. 3).
  • the two shafts 27 support an introduction assembly 10, used to insert the reinforcement rods 39 into the holes prepared by the drilling assembly 30.
  • the introduction assembly 10 is able to be arranged selectively between a first position near the ground on one side of the drilling machine 20 and a second position near the ground on the other side of the drilling machine 20.
  • the introduction assembly 10 comprises a relative mast, or guide beam, 28 connected to the shafts 27 by means of articulated joints 29 which allow it to incline due to the action of an actuator 35.
  • the mast 28 is of the folding type and, in its folded condition, that is, in its condition of minimum extension, is able to be arranged in the space defined between the two columns 17.
  • the mast 28 is made in four segments, connected together by hinge joints 36, in order from the front end to the rear end: first 28a, second 28b, third 28c and fourth 28d.
  • the segments 28a-28d are able to be selectively folded one on top of the other by activating a lower actuator 47 and two lateral actuators, front 48 and rear 49.
  • the lower actuator 47 has its shaft 47a constrained at the point of conjunction of two levers, a stationary lever 50 associated with the first segment 28a, and an oscillating lever 51 associated with the second segment 28b.
  • the front lateral actuator 48 in turn has its shaft 48a constrained at the point of conjunction of a stationary lever 52 associated with the second segment 28b, and an oscillating lever 53 associated with the third segment 28c.
  • the rear lateral actuator 49 has its shaft 49a constrained at the point of conjunction of a stationary lever 54 associated with the fourth segment 28d, and an oscillating lever 55 associated with the third segment 28c.
  • the mast 28 is in its working configuration wherein it assumes its maximum extension and has the relative segments 28a-28d aligned longitudinally (Figs. 1 and 5).
  • the mast 28 is in its folded position of movement, wherein it assumes its minimum extension and has the segments 28a, 28b and 28d substantially adjacent to the third segment 28c (Figs. 2 and 8).
  • the mast 28 is provided at the upper part with a toothed profile 37 (only partly shown in the drawings) which is also made in segments with an equal extension to that of the segments 28a-28d.
  • the toothed profile 37 consists of a rack.
  • the toothed profile 37 consists of a chain.
  • Three trolleys, a first 44, a second 45 and a third 46, are engaged on, and able to slide along, the toothed profile 37; a centering element 31 able to keep the reinforcement rods 39 on axis, a mandrel 32 able to make said reinforcement rods 39 rotate to facilitate their insertion into the holes, and an assembly 38 to support and wind the hydraulic equipment are mounted respectively on said trolleys 44, 45 and 46.
  • the movement of the trolleys 45, 46 is imparted by two speed reduction units mounted thereon; the first trolley 44 is able to be moved by the second trolley 45 to which it is connected by means of a cable 56 kept constantly under tension by a tensioning device mounted on the second trolley 45.
  • the first trolley 44 normally assumes the position shown in Fig. 1, in which it is kept stationary, even when the second trolley 45 moves back, by a stop element 57.
  • the introduction assembly 10 is arranged on one side of the drilling assembly 30 and operates simultaneously therewith, since it is completely independent therefrom.
  • the mast 28 is taken to its folded configuration in which it is contained longitudinally between the two columns 17 and is made to pass below the drilling assembly 30.
  • the mast 28 is folded quickly and completely automatically, as follows: First, the mandrel 32 and the supporting and winding assembly 38, which in the extended configuration of the mast 28 are arranged on the fourth segment 28d (Fig. 5), are made to advance onto the third segment 28c by means of the relative trolleys 45, 46 moved by the speed reduction units; also the centering element 31, already arranged on the third segment 28c, is made to advance slightly.
  • the third trolley 46 is drawn by the second trolley 45 and its speed reduction unit has a braking function, so that it makes a lower travel than that of the second trolley 45, in this case equal to about half.
  • the first trolley 44 on the contrary, is pushed by the second trolley 45 when the latter moves to the advanced position, with the tensioning device winding the connecting cable 56.
  • the front actuator 47 is activated to make the first segment 28a fold under the second segment 28b (Fig. 6).
  • the two lateral actuators 48 and 49 are activated simultaneously, and take respectively the second segment 28b, with the first segment 28a, and the fourth segment 28d to a position adjacent to the third segment 28c (Fig. 7).
  • the mast 28 has thus assumed its folded configuration and can thus be made to rotate, by means of the rotary plates 26 on which the shafts 27 are mounted, into the inner space between the two columns 17 in order to be taken to the opposite side of the drilling assembly 30; then the mast 28 is returned to its extended configuration to allow the introduction assembly 10 to start operations again.
  • the drilling assembly 30 has always continued working and therefore the interruption to the working cycle of the drilling machine 20 has affected the introduction assembly 10 only for a short period.
  • the mast 28 can consist of a larger or smaller number of segments, or be folded in a different way.
