Definitions

  • the invention relates to a tripod drilling device with a base plate, a guide column connected to the base plate and a drill which can be displaced along the guide column, the guide column and the drill having guide means which correspond to one another and a feed device is provided for the drill.
  • drilling devices of the type mentioned above have also been used as mobile devices in the construction industry for some time. Such drilling devices are mainly used together with diamond-tipped drill bits. These drill bits can also be used to produce breakthroughs with a larger diameter in iron-reinforced structures.
  • tripod drilling devices A major problem with these tripod drilling devices is the guidance of the drilling device. Due to the outreach of the drilling device required for the largest borehole knife and the forces to be exerted, in particular with the larger tools, high tilting moments and Large bending and torsional loads occur on the guide column. As mentioned, these devices must be mobile and, if possible, be handled by one or at most two people. The guide column can therefore not be reinforced arbitrarily due to the increasing total weight of the drilling device.
  • the guide column has a U-shaped or C-shaped cross section.
  • the drill is mounted on guides inside the guide column.
  • the processing of the guides by their arrangement inside such a guide column is very complex and can usually only be done with special tools. Since, due to the cross-sectional design, only the part of the drilling device provided with the bearing for the drilling spindle can protrude beyond the guide column, the feed device for the drilling device must also be arranged inside the guide column. This means that a complex construction with gear, threaded spindle and threaded nut is required.
  • the invention has for its object to provide an economically producible tripod drilling device, in particular guide column and feed device are characterized by a simple structure.
  • the guide column consists of two supports arranged at a lateral distance from one another and running parallel to one another, the supports having the guide means for the drilling device arranged therebetween and engagement means for the feed device.
  • the guide column thus consists of two parts, which can be manufactured and processed individually. Since the guides on the supports are freely accessible, much larger, more rationally working tools can be used for their processing. A major advantage of dividing the guide column into two supports is also that the guide column does not form a trough for the large amount of cooling water required for stone processing using diamond tools. For example, when drilling on a wall, the cooling water can flow freely between the two supports that run horizontally in such an application.
  • the drilling device can project beyond the guide column not only on the side of the spindle bearing, but also on the opposite side. This enables the feed device to be arranged on the outside of the guide column.
  • extruded or extruded profiles made of light metal alloys are preferably used for the guide column.
  • the molding costs are relatively high in both processes.
  • the fixed molding costs can thus be distributed over twice the amount of profiles, so that they can be manufactured much cheaper.
  • standard profiles from the semi-finished product manufacturers can also be used. Such profiles are particularly cheap because they are manufactured in large quantities.
  • the guide column required for this is relatively long.
  • a cover plate connecting the carriers to one another at the end of the carrier opposite the base plate.
  • the cover plate can be screwed, riveted or welded to the free ends of the carrier.
  • such a cover plate also fulfills another function. In this way, the rear end position of the drilling device can be limited by the cover plate and inadvertent movement out of the guide column can be prevented.
  • the guides on the guide pillar must absorb forces acting in different directions.
  • Dovetail-shaped guides also allow the operating clearance to be set in a relatively simple manner. Since the guides are easily accessible due to the two-part design of the guide column, machining of the guide strips is possible at most.
  • the guides are subject to relatively high wear.
  • the play in the guides is increased due to wear. If this game becomes too large, trouble-free working is no longer possible, so the game must be eliminated. This can be done for example by adjustable guides.
  • setting the correct game is very time-consuming and usually cannot be carried out by the operator himself.
  • An expedient solution is that the counter profiles are detachably connected to the drilling device. If the wear has become too large, the counter profiles can easily be exchanged for new, suitable ones. The time-consuming adjustment work is not necessary.
  • the interchangeable design of the counter profiles means that plastics with good sliding properties can also be used Shafts such as polyamide (“nylon”), polytetrafluoroethylene (“Teflon”) or the like. Such plastics also have a certain elasticity and can therefore adapt to the guides on the carriers.
  • An advantageous embodiment consists in that the engagement means on the carriers are designed as a toothed rack for the feed device arranged on the drilling device.
  • a feed device working by means of a rack enables the use of standardized components. If the stroke of a tripod drilling device according to the invention is to be changed subsequently, for example by lengthening or replacing the guide column, the toothed rack can be used again and can also be lengthened by a corresponding amount. Racks can also be purchased as standard yard goods and adjusted to the length of the guide column.
  • the drill can be connected to the rack, for example, via a worm shaft.
  • a feed device is usually self-locking. This means that the drill automatically remains in the respective position regardless of the position of the guide column.
  • a disadvantage of such a feed device is that the transmission ratio is very large and, in particular, the return stroke and the feed into the last position, for example for removing the drill core, are very time-consuming.
  • the feed device it is therefore expedient for the feed device to have a drive shaft connected to a pinion.
  • This pinion can be in constant engagement with the rack and can be driven manually or by a motor, for example using a handwheel.
  • the drive shaft can also be provided with driving means at both ends, so that the handwheel depends on the position the drilling device can be placed on the left or on the right side of the drilling rig.
  • the stand drilling device according to the invention shown in FIGS. 1 and 2 has a base plate 1 and a guide column, designated overall by 2, connected to the base plate 1.
  • the guide column 2 consists of two supports 2a, 2b arranged at a lateral distance from one another and running parallel to one another. The ends of the supports 2a, 2b opposite the base plate 1 are connected to one another via a cover plate 3.
  • a drilling device generally designated 4 is slidably arranged.
  • the drilling device 4 is connected to a tool holder 5, in which a drilling tool 6 is inserted.
  • the carriers 2a, 2b have dovetail-shaped strips 2c, 2d which are in engagement with correspondingly designed counter profiles 7.
  • the counter profiles 7 are detachably connected to the drilling device 4. If necessary, the counter profiles 7 can thus be replaced quickly and easily.
  • the drilling device 4 has a drive motor 4a and two arms 4b, 4c projecting laterally.
  • the arms 4b, 4c are also provided with interchangeable jaws 8, which are supported on the front edge of the carrier 2a, 2b.
  • the carrier 2b is connected to a rack 9.
  • This rack 9 is used to feed the drill 4.
  • a total of 10 is indicated drive shaft on the drill 4 rotatably mounted.
  • the drive shaft 10 is provided with a pinion 10 a, which is in engagement with the rack 9.
  • this has a polygon 10b at both ends.
  • a handwheel 12 is attached to the polygon 10b.
  • the handwheel 12 can also be removed and placed on the polygon 10b on the opposite side.
  • a stop 13 is provided to limit the drilling depth.
  • This stop 13 can be locked in any position with the aid of a sliding block 14 guided in a dovetail-shaped groove 2e, 2f and a clamping lever 15. If necessary, the stop 13 can also be arranged on the other support 2a. Since the two beams 2a, 2b have the same cross-section, they can easily be produced from the same profiles. This enables the profile to be produced in larger quantities and therefore more economically.
