Definitions

  • the invention refers to a device carrier of a feed device for an at least partially impacting tool device such as a hammer drill, preferably for the introduction of blasting holes in mining.
  • Heavy rotary hammers with more than 10 kg of mass, as used in mining, are detachably mounted on feed devices such as carriages with rotary spindle drive for dedicated use with a tool carrier, which automatically apply the feed to create the borehole.
  • the pneumatically or electrically driven power tools are usually air cooled or water cooled via the rinse.
  • a hammer drill with a pneumatic impact mechanism has a brushless, air-cooled electric motor electronically commutated via an inverter.
  • a striking tool device is detachably arranged on a feed device, which is hydraulically controlled by a hydraulic motor via a threaded rod applied feed. An introduction of the liquid from the feed device into the tool device does not take place.
  • DE3612762 is driven by a hydraulic motor, beating tool device by means of a device carrier arranged on a feed device, the feed of which is applied by a further hydraulic motor via a threaded rod. No liquid is introduced into the tool via the support arm.
  • WO96 / 06714 is a, often directly water-cooled, electric core drill mounted on a device carrier on a feed device.
  • the device carrier itself consists of a fork-shaped tool device holder and an associated eye of the feed device, which are navschwenkbar connected via a bolt, which partially axial and radially to the cylinder surface extending lubrication holes for Having lubrication of the equipment carrier, without supplying a rinsing or cooling liquid to the electric core drill.
  • the object of the invention is to realize a feed device for an at least partially impacting tool device with water cooling.
  • a feed device comprises a device carrier for an at least partially impacting tool device, which is connectable to a liquid-rinsed tool, wherein the device carrier forms, associated with an associated eye on the housing of the power tool, form-fitting fastener and the tool device via an axially into the eye insertable bolt is detachably connectable, wherein the bolt has axially and radially extending to the cylinder surface liquid lines, which is associated with appropriate use a running to the inner cylinder surface of the eye detergent line of the tool device.
  • the pin is limited axially displaceable by a positive stop, further advantageously resiliently biased, formed, which is a partial axial displacement of the bolt relative to the fastening means, the eye of the tool device from this removable, resulting in a simple assembly and disassembly.
  • the bolt is secured by a locked via a locking means stop at a complete withdrawal against loss, which is necessary in particular for use in mining for operational readiness.
  • the bolt is cantilevered on one side, firmly connected to a fastening means designed as a half fork head and has a through hole for a Sich ceremoniesssplint, whereby the heavy tool device in a first step can be fixed on the bolt by a single user and securable in a second step.
  • the pin is assigned an anti-rotation pin offset, which is positively engageable in the eye of the housing of the tool device, whereby the tool device via the bolt and the rotation locking pin fixed in position on the equipment carrier is fixed.
  • the bolt and the anti-rotation pin are each formed as legs of a U-shaped integrated male, whereby in one step, the bolt and the anti-rotation pin can be inserted through the fastener and the eye.
  • the rinsing or coolant line can be shut off within the device carrier, whereby additionally a separate barrier can be dispensed with.
  • the bolt is formed as a central part of a U-shaped lever, wherein the first leg serves as a shut-off lever for rotating the angular position of the bolt and the second leg as a detent against complete withdrawal of the bolt.
  • FIG. 1 has a device carrier 1 of a vertically movable to the drawing plane, indicated feed device 2 with a threaded rod for an indicated, perpendicular to the drawing plane beating tool unit 3, with an indicated, liquid lines 4 liquid-rinsed tool 5, an axially displaceable pin 6 with an outer, cylindrical functional surface , which is inserted through an associated eye 8 on a housing 9 of the power tool 3 in a running as a clevis attachment means.
  • the clevis has in a cheek on a flushing hole 10, which opens into a blind bore 11 in the end of the bolt 6 with a mutually closed central bore 12 and an associated Radial bore 13 liquid-tight engagement.
  • pin 6 is a liquid-conducting connection via the radial bore 13 in the on the inner cylindrical surface of the eye 8 of the housing 9 ending detergent line 4 available.
  • FIG. 2 has a device carrier 1 of a perpendicular to the drawing plane movable, indicated feed device 2 with a threaded rod for an indicated, perpendicular to the drawing plane beating tool unit 3, with an indicated, via liquid lines 4 liquid-rinsed tool 5, designed as cantilever-mounted pins pin 6 with an outer , cylindrical functional surface over which up to the stop on a fastening means 7 designed as a half clevis an associated eye 8 attached to a housing 9 of the tool device 3 and secured in this position with a passing through the pin 6 split pin as securing means 20.
  • the half fork head has in a cheek to a flushing hole 10, which opens into a blind bore 11, in the end of the bolt 6 with a mutually closed central bore 12 and an associated radial bore 13 is firmly connected liquid-tight.
  • FIG. 3 are in a third variant of the device carrier 1 of the bolt 6 and an axis-parallel anti-rotation pin 15 each formed as a leg of a U-shaped integrated, limited axially displaceable male member 16.
  • the anti-rotation pin 15 inserted through the fastening means 7 designed as a fork head and a fitting bore 17 parallel to the eye 8 has at its end a radially projecting screw as locking means 18.
  • a coil compression spring 19 is arranged between a cheek of the fork head and the locking means 18 coaxially about the anti-rotation pin 15.
