Definitions

  • the invention relates to a feed support device for an at least partially rotating and striking portable machine tool, preferably for drilling Blast holes in underground mining.
  • Such hydraulically, pneumatically or electrically driven, approx. 15 kg heavy, portable machine tools are usually with a water-rinsed long one Boring bar with a core bit with a hard material and a diameter of approx. 35 mm non-rotatably and axially limited movably connected.
  • a portable electric rock drill for drilling In underground mining a long, water-flushed boring bar with a blast hole Hard materials occupy the drill bit and a support device.
  • the feed is over the acting as a working cylinder hydraulically applied telescopic boring bar.
  • a portable machine tool is easy to assemble Feed support device can be supported on the device side against the floor and at the same time one Controllable feed force effective in the tool direction can be applied to the drilling tool.
  • the feed support device is on the back and sloping down.
  • a rotating and striking machine tool can be easily released and fluid-conducting with a one-legged support foot with a discreetly rotatable one controllable control valve connected. A sensitive manual control of the Feed support is not possible.
  • US1151261 is a fluid-powered striking machine tool with a axially arranged one-legged support leg, which is more effective as double-sided Working cylinder formed and its feed via a radially rotatable Worm wheel valve is continuously controllable by several revolutions. For manual Control over the entire control range of the feed support device is therefore a Relocation of the steering hand necessary.
  • the object of the invention is to implement a feed support device for a portable machine tool, which can be comfortably manually operated with one hand entire tax area is controllable.
  • a feed support device for an at least partially rotating and / or striking, portable machine tool as a fluid-powered working cylinder formed, which at a first end simply on the machine tool mountable mounting means and has a support foot at a second end, the Working cylinder via a manually rotatable actuator actuatable control valve is continuously controllable, the actuating part being transverse to Handle protruding from the working cylinder axis and adjustable around the handle axis is formed, which is within an angle of rotation of 180 °, preferably within of 90 °, the entire control range of the control valve is controllable.
  • control valve By means of the total that can be controlled within a rotation angle of 180 ° or 90 °
  • the control range of the control valve is comfortable without having to reach around with one hand Control and spatial fixation of the feed support device possible.
  • the continuously controllable control valve is advantageously designed as a rotary slide valve, whereby Technologically simple, the flow rate can be continuously regulated via the slide position.
  • the working cylinder is advantageously designed to be effective on both sides, as a result of which the return the boring bar is supported from the borehole.
  • the mounting means is advantageous as being partially non-rotating perpendicular to the drilling axis Bolt connection formed, further advantageously at the first end of the working cylinder a bolt that grips the eye of the machine tool and projects on one side is attached, which is further advantageously at least partially inside of one Fluid line is broken, which by a pressure hose in the Feed support device fed and over a branch point to the working cylinder and introduces fluid, branched to the assembly means, into the machine tool in a fluid-tight manner.
  • the working cylinder is advantageously hydraulically operated, which means that for rinsing and cooling the drill bit required water can be used as a pressure medium.
  • the support foot is advantageous over one, further advantageous with one with a cross pin Secured, tangentially removable claw realized, easy to install extension extendable, which makes the working area of the working cylinders in discrete steps is adjustable.
  • stirrup handle that can be moved and / or pivoted on the working cylinder available, which facilitates the ambidextrous transport of the feed support device.
  • the feed support device is a hydraulically operated, working cylinder 3 effective on both sides, which one at a first end mounting means 7 which can be easily mounted on the machine tool and on a second one End has a support foot 8.
  • the working cylinder 3 is manually on a manually rotatable actuating part 9 operable, designed as a rotary valve Control valve 10 continuously controllable.
  • the actuating part 9 is perpendicular to Working cylinder axis A projecting handle that can be rotated around the handle axis B formed, which is only adjustable within an angle of rotation of 180 °.
  • the Mounting means 7 is a partially non-rotating bolt connection perpendicular to the drilling axis formed by the eye 16 at the first end of the working cylinder 3
  • Machine tool penetrable, one-sided projecting bolt is attached, which is partially broken in its interior by a fluid line 11, which the of the Pressure hose 6 fed into the feed support device and via a Branching point 12 to the working cylinder 3 and to the mounting means 7 fluid branched in introduces the machine tool in a fluid-tight manner.
  • the support foot 8 is via a with a cross pin 13 secured, tangentially removable claw 14 at the second end of the working cylinder 3 attached.
  • On the working cylinder 3 there is a stirrup handle 15 which can be displaced and pivoted available.
