Definitions
- the invention relates to a hydraulic hammer with a Nozzle arrangement, consisting of several, around the axis of the hammer arranged spray nozzles, and if necessary a Hammer surrounding housing.
- a mobile used Impact head machine is the hydraulic hammer in Longitudinal direction with a jacket-shaped Impact protection housing surrounded, in the front Forehead a ring-shaped Nozzle arrangement with multiple spray nozzles attached is.
- the circularly shaped nozzle arrangement the face of the hydraulic hammer concentric to Chisel holder arranged.
- the nozzle arrangements are on the face of the hydraulic hammer or on this surrounding housing attached.
- the relatively small one There is a distance from the impact point of the chisel Series of disadvantages. So the grasped by the Nozzle arrangement overall generated spray cones only one certain area on the surface of the destructive rock. Through the impact energy of the Hammer's dissolved particles with high kinetic energy penetrate the spray cone outwards and withdraw thus the dust binding. Meet regardless such particles also on the relatively close Nozzle system and lead to blockages and Damage.
- the exchange of a hydraulic hammer with no longer working properly Nozzle arrangement leads to the interruption of the Operation.
- a pneumatic hammer according to the preamble of independent claim 1 is known with one connected to the handle Spraying device is provided, the three Has water outlet openings, the axis in turn is aligned parallel to the hammer axis.
- An upstream of the water outlet openings to the Hammer axis rotatable ring points alternately on his Handling arranged openings that the from the Spray water escaping axially pass the corresponding angular position of the ring leave, and hollow stems on which the spray water according to a different angular position of the ring on the side, d. H. away from the hammer axis.
- this hammer are the water outlet openings by their distance from the chisel tip is proportionate before falling rocks sure, the total spray cone generated is - at constant chisel length - unchangeable.
- From DE-A-40 20 773 is a hammer drill and chisel known in which the mouth of a single, axial sliding nozzle is directed to the chisel tip binding stone dust and the life of the Extend chisel tip by cooling. A change of the cone volume or "base area" of the spray cone not provided for this objective.
- WO 93/22106 discloses one Hydraulic hammer, the cylinder wall by others Surrounded walls, the cavity between the Cylinder wall and the other walls by a sound-absorbing material is filled. The further one Wall is, however, in one piece with the cylindrical wall connected. A separate housing is known in this Hydraulic hammer not available, so that by the Structure-borne noise is inadequate noise reduction is achieved.
- the object of the present invention is to achieve this to avoid the disadvantages mentioned, at least to reduce significantly and - positively expressed - the operational safety of a Hydraulic hammer with water spray to increase and the employment relationships, e.g. B. by lower Dust formation, improve.
- the setback also increases the "footprint" of the spray cone and the cone volume. It will thus on the one hand by the larger footprint more prone to dust formation Particles are captured and more particles remain within the (larger) spray cone. It will be the Proportion of particles bound by water spraying enlarged and dust formation reduced accordingly.
- the displaceability of the spray arrangement along the Side walls of the hydraulic hammer or, if applicable, surrounding housing in the direction of the main axis of the Hydraulic hammer can be the volume of the individual spray nozzles generated total spray cone and whose base area vary and the respective Adjust operating conditions accordingly, whereby the maximum possible spray cone volume is reached when the Nozzle arrangement at the rear end of the Hydraulic hammer or the housing surrounding it, if applicable is placed.
- a hydraulic hammer 1 according to FIG. 1 is from a sound insulation box 2 surrounded on all sides. At the front of the Hydraulic hammer 1 is a pointed chisel 3 inserted. At the rear end opposite the chisel 3 is the hammer 1 with the sound insulation box 2 over a Plate 4 attached to a bracket. The Bracket 5 in turn serves to attach the Hydraulic hammer on a (not shown) Carrier vehicle.
- the plate 4 forms together with the spray nozzles 9 Nozzle arrangement 10.
- the dashed lines 11 represent the Surface lines of a single spray nozzle 9 generated spray cone 12.
- the Dashed lines 13 the outer surface lines of the of all spray nozzles 9 represent a total of spray cones 14.
- FIGS. 2 and 3 are on the outer surfaces of the hydraulic hammer 1 ' enclosing sound insulation box 2 'parallel to Main longitudinal direction strips 15 with holes 16 appropriate.
- the nozzle arrangement 10 ' is the Adjusted outer contour of the sound insulation box 2 ', U-shaped educated. It has one for each bar 15 Recess 17 on. To attach the Spraying arrangement 10 'is this with angle tabs 18th provided with holes 19. If the holes 19 with the Holes 16 of the strips 15 are congruent, can the nozzle arrangement 10 'z. B. with bolt 20 be attached.
- the nozzle arrangement 10 ' has a corner central water connection 6 ', from which channels or Bores 21, 22, 23 to the different spray nozzles 9 lead. As is readily apparent from Fig. 2 is that covered by the entire spray cone 14 Base 24 by moving the Spray arrangement 10 'along the sound insulation box 2' be resized.
