Definitions

  • This invention relates to a synchronous vibratory hammer employing a driving and a driven eccentric weight arranged to produce action which may be used for impacting a tool upon a work surface.
  • the subject invention has certain elements in common with the device of US-A-3866693, however, it differs in at least one important respect, namely, it has no mechanical restraints which can absorb energy, such as would be caused by the guides 186 and 188 of US-A-3866693.
  • the mechanical restraints in US-A-3866693 are used to control non-linear motion of the hammer element being driven by a single eccentric.
  • the device of the subject invention eliminates the need for such mechanical restraints because of the fact that two eccentrics are used.
  • the device of the subject invention requires less maintenance than vibratory hammers having non-linear impacting vibrations, which not only shake the hammer supporting mechanism, but are subject to greater wear and breakage.
  • a primary purpose of the invention is to provide a vibratory hammer with improved operating efficiency, and which minimizes maintenance costs.
  • a vibratory impact hammer including a support frame, a hammer body assemblage suspended within the support frame by resilient means arranged to provide guiding and damping action in either direction of axial movement of the hammer body assemblage, said hammer body having a given stroke, said resilient means being the sole means engaging the hammer body assemblage so that extraneous frictional forces are avoided, vibration drive means arranged to develop a forcing frequency to vibrate the hammer body assemblage in an axial direction, and a tool reciprocably mounted in the support frame and positioned to receive impact blows of the hammer body assemblage when reciprocated by the vibration drive means, characterized in that said drive means forcing frequency leads to hammer body assemblage by 135°.
  • numeral 1 identifies a vibratory hammer having a support frame consisting of a pair of side plates 3, which are maintained in parallel position by means of tubular space bars 5, welded to the plates, as well as a tool holder element 7, similarly welded thereto.
  • a hammer body assemblage 9 (Fig. 6) is suspended between the side plates 3 by resilient means consisting of four rubber mounts 11 affixed to the side plates and the hammer body assemblage by means of bolts 13 and 15.
  • the mounts serve as the sole guiding and damping means for the assemblage when the latter is vibrated during tool operation.
  • the hammer body assemblage 9 includes an eccentric weight chamber 17 enclosing a pair of eccentric weights 19 and 21, mounted upon shafts 23 supported in roller bearings 25 positioned in end caps 27, the latter being secured by bolt means 29 to side members 31 of the eccentric weight chamber 15 by bolts 32.
  • an upper arm member 33 Projecting from the top surface of the eccentric weight chamber 17 and affixed thereto, is an upper arm member 33 adapted to be affixed to the rubber mounts 11 by the bolts 15.
  • a lower arm member 35 Projecting from the bottom surface of the eccentric weight chamber 7 and affixed thereto, is a lower arm member 35 adapted to the rubber mounts 11 by the bolts 15. Brace members 37 are secured to the sides of the lower arm member 35 and the hammer body assemblage 9, to stabilize the arm member.
  • An hydraulic motor 39 affixed to the end of shaft 23, is provided to rotate the eccentric weight 19.
  • a pair of gears 41, mounted upon the shaft 23, is arranged to transmit rotary motion from the shaft which supports eccentric weight 19, to the shaft which supports eccentric weight 21, so that both weights are rotated at the same speed, but in opposite directions.
  • Hose means 43 supply pressurized hydraulic fluid to the motor 39 when desired, from a power source, not shown.
  • a striker plate 45 affixed thereto by means of pin 47.
  • the striker plate is arranged to impact upon a conical tool 49 mounted in the tool holder element 7 as best seen in Fig. 2.
  • Retaining means including a key 51 projecting into a slot 53 formed in the tool 49, allow reciprocal movement of the tool.
  • the tool slides in bushings 55 supported in a bushing housing 57, the latter positionally maintained against axial movement by a tool stop plate 59, affixed to the end of the tool holder by means of cap screws 61.
  • Support means for the vibratory hammer 1 are provided by a pivotally attached linkage assemblage 63, which may be operatively positioned by power machinery, e.g., tractor, not shown.
  • a vibratory hammer in accordance with the invention will have the following numeral values, if a work impact output of 200 ft.-Ibs. (271.15 N-m) at 1200 rpm is to be achieved:
