Definitions

  • the invention relates to a device carrier of a feed device for at least one partially striking tool device such as a hammer drill, preferably for insertion of blast holes in mining.
  • Feed devices such as carriages with a rotating spindle drive are mounted, which automatically Apply feed to create the drill hole.
  • the pneumatic or electric High power powered tooling tools are typically air cooled or over the air Water-cooled detergent.
  • a rotary hammer with a pneumatic hammer mechanism has one Brushless, air-cooled, electronically commutated via an inverter Electric motor on.
  • a striking tool device is detachable on one Feed device arranged, the one of a hydraulic motor via a threaded rod applied feed is hydraulically controlled. An introduction of the liquid from the Feeding device into the tool device does not take place.
  • DE3612762 is a striking driven by a hydraulic motor Tool device arranged by means of a device carrier on a feed device, the Feed from another hydraulic motor is applied via a threaded rod. about no liquid is introduced into the tool arm of the support arm.
  • an electric core drilling machine is over an equipment carrier attached to a feed device.
  • the equipment carrier itself exists from a fork-shaped tool holder and an associated eye of the Feed device, which are pivotally connected via a bolt, which partially axial and radial lubrication holes to the cylinder surface Has lubrication of the equipment carrier without a flushing or cooling liquid Feed the core drill.
  • the object of the invention is to implement a feed device for a at least partially beating tool device with water cooling.
  • a feed device has an implement carrier for at least one partially beating tool device, which with a liquid-rinsed Tool can be connected, the device carrier on, an associated eye on Forms form-fitting fastening means assigned to the housing of the tool device and detachable with the tool device via an axially insertable bolt into the eye is connectable, the bolt extending axially and radially to the cylinder surface Has liquid lines, which when used appropriately Inner cylindrical surface of the eye running detergent line of the tool assigned.
  • the feed device with the equipment carrier which is on a Detergent line such as a water line, is connected via the liquid lines the fastener and the bolt on the tool and advantageously further realized a detergent line via the tool, which means that the Tool during assembly or disassembly on the feed device separate connection or disconnection of the detergent line is not necessary.
  • the bolt is advantageously axially displaceable to a limited extent by a positive stop, further advantageously resiliently biased, formed, whereby a partially axial Displacement of the bolt relative to the fastener from the eye of the tool this can be removed, resulting in simple assembly and disassembly.
  • the bolt is advantageous due to a stop locked by a locking means a complete pull-out against loss, which is particularly important when used is necessary for operational readiness in mining.
  • the bolt is cantilevered on one side, fixed with one as half Clevis trained fastener connected and has a through hole for a split pin, which means that the heavy Tool device can be fixed on the bolt in a first step and in a second step can be secured.
  • An anti-rotation pin which is advantageously offset, is assigned to the bolt can be positively engaged in the eye of the housing of the tool device, which Tool device fixed in position on the bolt and the anti-rotation pin Device carrier is fixable.
  • the bolt and the anti-rotation pin are each advantageous as a leg of a U-shaped Integrated insert element formed, which in one step Bolt and the anti-rotation pin can be inserted through the fastener and the eye is.
  • the rinsing or is advantageous by rotating the angular position of the bolt can be shut off within the equipment rack, which also means a separate one Barrier can be omitted.
  • the bolt as the central part of a U-shaped lever is advantageous formed, the first leg as a locking lever for rotating the angular position of the bolt and the second leg as a lock against complete withdrawal of the bolt.
  • an equipment carrier 1 has a movable, perpendicular to the plane of the drawing, indicated feed device 2 with a threaded rod for an indicated, perpendicular to the drawing plane hitting tool device 3, with an indicated, over Liquid lines 4 liquid-flushed tool 5, an axially displaceable pin 6 with an outer, cylindrical functional surface, which in one as fork head executed fasteners 7 by an associated eye 8 on a housing 9 of the Tool device 3 is inserted.
  • the fork head has one in a cheek Flushing bore 10, which opens into a blind bore 11, into which the bolt 6 ends with a mutually closed central bore 12 and an associated Radial bore 13 engages liquid-tight.
  • an equipment carrier 1 has a movable, perpendicular to the plane of the drawing, indicated feed device 2 with a threaded rod for an indicated, perpendicular to the drawing plane hitting tool device 3, with an indicated, over Liquid lines 4 liquid-rinsed tool 5, one projecting on one side attached pin executed bolt 6 with an outer, cylindrical functional surface on, up to the stop on a half fork head Fastening means 7 an associated eye 8 on a housing 9 of the tool device 3 attached and in this position with a split pin passing through the bolt 6 is secured as a securing means 20.
  • Half of the fork head has one in one cheek Flushing bore 10, which opens into a blind bore 11, into which the bolt 6 ends with a mutually closed central bore 12 and an associated Radial bore 13 is firmly connected liquid-tight.
  • the bolts 6 and 1 are in a third variant of the device carrier 1 axially parallel anti-rotation pin 15 each as a leg of a U-shaped integrated, axially displaceable insertion element 16 is formed. That through the fork head executed fasteners 7 and a parallel to the eye 8 fitting hole 17 inserted Anti-rotation pin 15 has a radially projecting screw at the end Locking means 18 on. Between a cheek of the clevis and the Locking means 18 is a spiral compression spring 19 coaxially around the anti-rotation pin 15 arranged.
