  • Such a tap hole drilling machine was already described in DE-A-19 62 953 in 1967 described.
  • This machine includes a fixed console and one Boom with its first end pivotable about a first axis in the fixed console is stored.
  • the boom which is powered by a a first working position in front of the first tap hole in a second working position is pivotable in front of the second tap hole, carries at its free end a vertical pivot to which a drill carriage is attached.
  • a handlebar is by means of swivel joints with a fixed lever arm on the Console and connected to a crank firmly seated on the pivot.
  • a four-link swivel gear is formed, in which one Swiveling movement of the boom around the first axis is a swiveling movement the carriage around the second axis.
  • the drill carriage is able to adapt the drilling axis to the respective tap hole connected to vertical pivots by means of a horizontal swivel joint, and a tilt cylinder is between the drill carriage and one rigid on the vertical Trunnion attached flange arranged.
  • the respective tap hole to the drill carriage to approach the taphole differently, that is the Limit swivel movement of the boom.
  • this requires that only very small differences in height can be compensated for, firstly because Swiveling movement of the boom determines the end position of the drill carriage, and secondly, the distance between the carriage end and the tap hole should be as equal as possible should be.
  • a rock drilling machine is known from US-A-3,374,975, e.g. is used in mines.
  • This rock drilling machine has a parallelogram gear with a frame, three limbs and four joints on that a parallel displacement of a drill carriage by means of a first pressure cylinder enables.
  • a second pressure cylinder is between the parallelogram gear and the drill carriage is switched and enables the drill carriage to tilt.
  • An additional rotary motor enables a 360 ° rotation of the Parallelogram gearbox around a horizontal axis.
  • the aim of the device is the drill carriage via a hydraulic control system relative to a horizontal one Align the axis universally, so that the rock drill can drill a plurality of holes without repositioning them got to.
  • a tap hole tamping machine in which one Stuffing cannon using two articulated support members on a support structure is hung.
  • a pressure cylinder enables the stuffing cannon in one to pivot vertical plane and so the latter with her nose firmly against the To press the stitch hole.
  • One of the two support members is adjustable in length, so that the inclination of the stuffing gun is adapted to the inclination of a tap hole can be.
  • the present invention has for its object a tap hole drilling machine to operate two stitch holes to create the two different can reach high and steep stitch holes optimally ..
  • the suspension device has a transmission with a frame, a first drive and two connection points on.
  • the transmission is constructed in such a way that a drive pulse of the first drive a positively driven displacement of the two connection points can be generated relative to the frame, in such a way that a connecting line through the two connection points during this shift stays parallel to yourself.
  • a tilting device is with a connecting joint, a ball joint and a second drive equipped and such built that the distance by a drive pulse of the second drive is adjustable between the connecting joint and the supporting joint. It is about that Connection joint at a first of the two connection points of the transmission attached.
  • the tilting device on its support joint with the drill carriage, the second connection point of the transmission by means of a support joint with the Drill mount, and the frame connected to the support structure.
  • the tilting device via their support joint with the support structure, the second connection point the transmission by means of a support joint with the support structure, and the drill carriage connected to the frame.
  • the height can be adjusted in both versions adjust the drill carriage via a single drive, without this Inclination of the drill carriage is changed.
  • the transmission is driven by a first pressure cylinder, the one stroke limiting device with two independently of each other adjustable strokes. So the drill carriage, which when starting a Stitch hole is raised to a rest position, in the working position to the height be lowered by two differently high stitch holes.
  • the tipping device is driven by a second pressure cylinder, which is also a Stroke limiting device with two independently adjustable Strokes, so that the drill carriage, which when starting a Taphole advantageously located in a horizontal rest position, in the working position adapted to the inclination of two differently steep stitch holes can be.
  • the transmission comprises a frame and three links which are connected by means of four rotary joints A , B , C and D.
  • the distance from joint A to joint D corresponds to the distance from joint B to joint C
  • the distance from joint A to joint B corresponds to the distance from joint D to joint C
  • the distance from joint A to support joint E of the transmission Distance from joint B to support joint F of the tilting device corresponds to the distance from joint B to joint C.
  • the transmission could, for example, also have two X-shaped ones Have links connected in their middle by an additional swivel are.
  • the frame and a third link are then each simple Swivel joint and a combined swivel joint with the ends of two X-shaped arranged links connected, the geometric arrangement this pivot joints advantageous the geometric arrangement of the corner points of a rectangle.
  • This version has the advantage that a pure vertical displacement of the drill carriage, without horizontal movement component is achievable. However, it is much more than that thanks to the rotating thrust joints more complicated to set up and requires considerably more space.
  • the tilting device is advantageously designed as scissors. With these scissors the second pressure cylinder can be attached particularly easily. By opening and closing the scissors, the second pressure cylinder allows the distance between the connecting joint and the supporting joint of the tilting device.
  • the suspension device 12 is described in more detail below with reference to FIG. 2. It includes a flat four-link gearbox with four swivel joints.
  • a first link 18 is designed as a frame of the transmission and is fastened to the support structure 14.
  • This first link 18 has two legs 20 and 22.
  • the first leg 20 is connected to a second link 24 via a joint A.
  • the latter is L-shaped with a first arm 26 and a second arm 28, the joint A being arranged at the intersection of the two arms 26 and 28.
  • the second leg 22 of the first link 18 is connected to a third link 30 via a joint B.
  • the latter is also L-shaped with a first arm 32 and a second arm 34, the joint B being arranged at the intersection of the two arms 32 and 34.
  • a fourth link 36 which is designed, for example, as a rod, is connected to the second arm 28 of the second link 24 via a joint D and to the second arm 34 of the third link 30 via a joint C.
  • the four links 18, 24, 30 and 36 are designed such that the distance from joint A to joint D corresponds to the distance from joint B to joint C , and the distance from joint A to joint B corresponds to the distance from joint D to joint C. corresponds.
  • the transmission has two connection points E 'and F'.
  • the connection point E ' is located on the first arm 26 of the second link 24 and it is assigned a swivel joint E which connects the gearbox to the drill mount 10.
  • the connection point F ' is located on the first arm 32 of the third link 30.
  • the drive of the four-link transmission described above is formed by a pressure cylinder 38.
  • the latter is articulated in the transmission with its first end to the frame 18 and articulated with its second end to the second arm 34 of the third link 30.
  • the piston rod 40 of the pressure cylinder 38 is retracted.
  • the piston rod 40 of the pressure cylinder 38 is extended.
  • the extension of the piston rod 40 caused the third link 30 to rotate about the joint B.
  • This rotary movement was transmitted to the second link 24 via the fourth link 36. Due to the above-described arrangement of the joints A , B , C and D on the corner points of a parallelogram, the angle of rotation of the second link 24 around the joint A corresponds exactly to the angle of rotation of the third link 30 around the joint B.
  • a tilting device 42 is connected to the first arm 32 of the third link 30 via a connection joint F at the connection point F ′, and is connected to the drill mount 10 via a support joint G.
  • the distance from the joint A to the support joint E corresponds to the distance from the joint B to the connection joint F, whereby a drive pulse of the first pressure cylinder 38 generates a positively guided displacement of the support joint E and the connection joint F relative to the frame 18, so that an imaginary connecting line through the two Connection points E 'and F' remain parallel to themselves during this shift. It follows from this that the drill carriage 10 can also be raised and lowered parallel to itself by the pressure cylinder 38.
  • the height of the drilling axis can thus be determined without changing the inclination of the drilling mount 10 and thus the inclination of the drilling axis. It should be emphasized in particular that the above-described transmission is extremely compact in construction and at the same time introduces forces in the longitudinal direction of the drilling mount 10 relatively rigidly into the support structure 14.
  • the tilting device 42 is designed such that the distance between the connecting joint F and the supporting joint G is adjustable.
  • it comprises, for example, two-part scissors 44 with an H joint.
  • a pressure cylinder 50 is articulated on the one hand to the first link 46 and on the other hand articulated to the second link 48 of the scissors 44 and thus makes it possible, by opening and closing the scissors 44, to increase and decrease the distance between the joint F and joint G.
  • the pressure cylinder 50 could of course also be connected directly, ie without scissors 44, via a connecting joint F to the first arm 32 of the third link 30 and via a supporting joint G to the drill mount 10.
  • the pressure cylinder 50 can be mechanically integrated into the suspension device 12 in a far more favorable manner. Comparing FIG. 2 with FIG. 3, it can be seen that the distance between the joints F and G was shortened by retracting the piston rod of the pressure cylinder 50. As a result, the support joint G was raised relative to the support joint E , so that the drill carriage 10 has inclined forward.
  • the frame of the transmission is formed, for example, by the drilling mount and the two supporting joints E and G are connected to the supporting structure.
  • FIG. 4 and 5 show an advantageous embodiment of the two Printing cylinders 38 and 50 described.
  • It is a pressure cylinder 100 with a main piston 104 which is fitted into a cylinder chamber 102 and its stroke in the cylinder chamber 102 via an attached stroke limiting device is adjustable.
  • the latter also includes an auxiliary piston 106 a piston boss 108 which is sealed into the cylinder chamber 102 is.
  • the auxiliary piston 106 seals a pressure chamber 110, which with a Media can be applied.
  • a nozzle 112 is sealed from the Pressure chamber 110 guided and here has a thread 114 with two screwed Nuts 116 and 118.
  • the pressure chamber 110 is depressurized.
  • the main piston 104 is on Piston shoulder 108 and the latter up to the stop of the nut 116 push back a bracket 120.
  • the Piston shoulder 108 protrudes only slightly into the cylinder chamber 102, so that the The stroke of the main piston covers the entire length of the cylinder chamber 102 corresponds.
  • the pressure chamber 110 is at the same pressure as the rear part applied to the cylinder chamber 102.
  • the piston shoulder 108 now projects significantly into the cylinder chamber 102 and limits the stroke of the main piston 104. Since the cross section of the pressure chamber sealed by the auxiliary piston 106 110 larger than the cross section sealed by the main piston 104 the cylinder chamber 102, the main piston 104 can the piston boss 108 no longer push back.
  • the second nut 118 enables this the depth of penetration of the piston shoulder 108 into the cylinder chamber 102 limit.
