Definitions

  • the invention relates to a rod magazine for receiving a plurality of boring bars of a rock drilling machine with a carriage and a longitudinally displaceable drilling motor with a rotary drive shaft thereon, each of which has a lower, the weight of the boring bars and an upper, actuatable by a magazine motor, the boring bars each encompassing a guide fork linear and synchronous displacement of the boring bars before their repositioning and after their pulling in an aligned plane extending through the axis of the rotary drive shaft.
  • the guide forks of the lower and upper receiving device are provided in their inner surfaces with the boring bars adapted, successively different radii, by means of the axial displacement of an inner surface to the respective opposite inner surface, the boring bars can be clamped .
  • the lower and the upper receiving device are each moved via a toothed rack by a hydraulic motor via a common drive shaft both in the direction of the rotary drive shaft and therefrom.
  • This rod magazine suffers from the disadvantage that, on the one hand, for repositioning and pulling a boring bar, the two receiving devices have to be moved completely in the direction of the rotary drive shaft and, on the other hand, the complicated tolerance adjustments of the radial arches in the inner surfaces of the guide forks in connection with the play of the racks and gears require such fine-tuning, which can only be of short duration due to the rigid machine parts and the rough drilling gear.
  • Another rod magazine of the aforementioned type according to DE-PS 21 48 357 has a complicated pawl lock for the boring bars, which replaces the clamping of the previously described mutually displaceable inner surfaces of the guide forks. It is also noticeable here that the complete receiving devices have to be moved or removed in the direction of the rotary drive shaft for setting and pulling, and all parts except for the pawl lock are arranged relatively rigidly to one another and lack a tolerance-compensating elasticity.
  • the invention has for its object to provide a rod magazine of the type mentioned, the receiving devices are characterized on the one hand by a relatively light and space-saving design and on the other hand only so far in the direction of the rotary drive shaft of the drill motor or are to be removed from it, as is necessary for a safe delivery or reception of the boring bars when repositioning or pulling while simultaneously compensating for the tolerance play of the boring bars with one another.
  • the guide forks of the lower and the upper receiving device are provided with smooth, straight and parallel inner surfaces, on the open ends facing the rotary drive shaft, the boring bars each of an unlockable bolt and are held at their opposite ends by a slider, which is displaceable by the magazine motor via a chain, rope or belt guided around a plurality of deflection rollers in the direction of the axis of the rotary drive shaft.
  • the receiving devices only need to be moved according to the distance from their parking position into the delivery or receiving position to the rotary drive shaft, since the pipe to be added has to be moved over the chains, the ropes or the belts and along the smooth inner surfaces the guide forks are always pressed against the unlockable bolt in hydraulically elastic and thus compensating tolerances. Due to these short distances, correspondingly short travel times are ensured and the boring bars are shifted as far as possible within the guide forks from the sliding pieces via the chains, the ropes or the belts in the upper and lower holding device from the magazine motors in the direction of the rotary drive shaft .
  • the bolts each consist of a hydraulically actuated locking bolt, which with a conical projection either narrow the open end of the guide forks for locking the boring bars or release them for pushing them through.
  • These locking bolts are also under the action of a mechanical spring securing their locking position.
  • the upper and the lower receiving device can advantageously be displaced in the direction of the rotary drive shaft and in the opposite direction by means of a hydraulic cylinder each having one end on the mount and the other end on the guide fork.
  • the repositioning and the pulling of a boring bar must be distinguished from one another.
  • the two holding devices can be moved according to the invention by their hydraulic cylinders so far in the direction of the rotary drive shaft until the boring bar lying against the locking bolt comes into contact with two guides running on the carriage, is aligned in this position with the axis of the rotary drive shaft of the drilling motor and can be screwed to it.
  • the locking bolts can then be unlocked.
  • the holding devices with the boring bars located therein are moved into a parking position.
  • Both the repositioning process and the subsequent locking always take place under the action of a hydraulic spring and thus in a gentle manner, hydraulically and elastically, be it under the action of the hydraulic cylinders or be it under the action of the hydraulically actuated magazine motors.
  • the receiving devices can be displaced away from the axis of the rotary drive shaft into a parking position via their hydraulic cylinders.
  • the pulling of a boring bar is carried out according to the invention in that the holding devices for receiving a drawn boring bar hanging from the rotary drive shaft and detached from the drill pipe can be displaced from its parking position in the direction of the axis of the rotating drive shaft by the hydraulic cylinders, the locking bolts shortly before reaching the pulled boring bar by a Non-contact switches can be opened and the boring bar can be pushed into the upper and lower holding device against the force of the hydraulic springs formed by the magazine motors, the chains, ropes or belts and the sliding pieces and can be clamped therein by the hydraulic cylinders until the locking bolts reach the open end of the Lock the guide forks again.
  • the boring bar can then be detached from the rotary drive shaft of the drilling motor.
  • the control pulse for the locking bolt can advantageously be triggered by contactless switches in conjunction with switching flags.
  • the chain, the rope or the belt for displacing the sliding piece and thus for the gentle displacement of the drill rods in the guide forks is arranged from an initial fastening arranged on the arm of the guide forks in the vicinity of the respective locking bolt via two arranged on the sliding piece Deflection rollers and from there via a deflection roller located near the respective locking bolt on the other arm of the guide fork, and from there via the magazine motor and a fourth deflection roller attached to the motor-side end of the slide piece, to an end fastening on the guide fork near the magazine motor.
  • This arrangement allows the boring bars, which are slidably held in the guide forks, after the opening of the locking bolts, to be smoothly displaced from the slider by actuating the hydraulic magazine motor into the guides aligned with the axis of the rotary drive shaft when a boring bar is being adjusted.
  • a drawn boring bar can be pressed into the open end of the guide forks in a manner that is just as gentle against the hydraulic cylinders and hydraulic magazine motors that act as hydraulic springs take their locking position in front of the locking bolts.
  • the chains, ropes or belts which act on the sliding pieces are held at their start and end attachments on a locked screw bolt and can be tightened over its screw length.
  • FIGS. 1 and 2 show a mobile drilling device (1) with a rock drilling machine (2) with a mount (3) and a drill motor (4) with a rotary drive shaft (5) which can be moved longitudinally thereon.
  • FIG. 2 shows its top view with the vehicle omitted.
  • the rod magazine (6) has a lower one (7), which holds the weight of the boring bars (8) in a storage rail (7a) (see FIG. 3) and an upper one (9), each of which can be actuated by a hydraulically operated magazine motor (10).
