Definitions

  • the invention relates to a hydraulic drilling device, which consists of a hydraulically driven hammer drill and a hydraulic feed unit with a control of the hydraulics.
  • Hydraulic drilling rigs are used to drill mounting holes and blast holes in the rock. A preferred area is mining. An overview of the status of hydraulic drilling rigs can be found in the article "Hydraulic Rockdrills" by Joffrey Pearse (Mining Magazine - March 1985, pages 221 to 231, Mining Journal Ltd., 60 Worshipstreet, London EC2A 2HD), in which the products of various manufacturers and their application are described. Telescopic cylinders for generating the feed and retraction movement are known for hand-operated rotary hammers and for drilling equipment on carriages, hydraulic feed and retraction devices on rotary hammers so far as elements of closed ones hydraulic circuits can be operated with oil or with water emulsions.
  • the invention provides a remedy here. It solves the task of reducing the number of flexible supply lines and flexible internal connecting lines of a hydraulic drilling device to a minimum and the location of the supply device within wide limits, e.g. in mining on the surface of the earth.
  • the object is achieved by using the cooling and rinsing water for the drill bit as an energy source for all movements carried out by the drilling device, by using a single hydraulic supply line from outside the drilling unit as an energy source for driving the feed unit, as well as for the drive and rinsing the drill bit to the Control is performed on the device, and by installing only a single hydraulic supply line to the hammer drill from the hydraulic feed unit with control, which transmits the drive power for the hammer drill and the flushing fluid for the drill bit.
  • the missing geodetic gradient for the operation of the drilling device is generated by pressure booster pumps somewhere between the water reservoir and the drilling machine and after the pump, the flushing water network is designed to be more powerful in accordance with the pressure increase.
  • the drilling device is equipped with a minimum of supply lines, which simplifies handling, and that, by using rinsing water as an energy source for drilling, no further electric motors or internal combustion engines with their necessary infrastructure on site or below Days are necessary.
  • a hydraulic drilling device which consists of a hydraulically driven hammer drill 1, which is pivotally attached to a hydraulic feed unit 10 and a hydraulic feed unit 10 with a control 14 of the hydraulic system, with cooling and rinsing water according to the invention for the drill bit 3 is used as an energy source for all movements carried out by the drill.
  • a single hydraulic supply line 6 with coupling piece 4 is guided from outside the drill as an energy source for driving the feed unit 10 and for driving and flushing the drill bit 3 to the control 14 and is only a single hydraulic supply line 5 with coupling pieces 4 from the hydraulic feed unit 10 with controller 14 to the hammer drill 1, which transmits the drive power for the hammer drill 1 and the flushing air liquid for the drill bit 3.
  • the hammer drill 1 with handle 2 and with inserted drill bit 3 is connected to an intermediate piece 7 of the feed unit 10 via a transmission piece 8 by hinge bolts 17, 18.
  • a connecting web 23 of the transmission piece 8 is fixed via a retaining screw 16 between a damping disk 19 and a damping device 9.
  • the feed and retraction movement is transmitted via a foot 15 supported on the floor by an actuating cylinder 12 with a piston acted on on both sides via a guided piston rod 11 to the housing of the control part 14 and through the intermediate piece 7 and that Transfer piece 8 passed to the hammer drill 1.
  • the piston surfaces are pressurized by channels in the hollow piston rod 11 on the side towards the support foot 15 and on the other side towards the cylinder cover 13.
  • a rotary valve 20 which can be rotated between two end positions via an actuating lever 22, the reversal between the feed movement and the retracting movement is carried out on the one hand by rotating over a neutral locking angle and on the other hand the hydraulic feed line 5 with energy and flushing water to the hammer drill 1 is blocked as soon as the rotary valve 20 is turned from the feed area into the neutral locking angle.
  • the maximum feed rate is specified by changing a throttle point by setting the setpoint by turning a feed setting 21, which for operational reasons is preferably built on the rotary valve 20 itself.
