  • the unbalance units are driven in rotation via one or more rotary drives by means of gear drives.
  • the unbalance units and the gear transmission are arranged in a transmission housing, which is filled to reduce friction and frictional heat with transmission oil. Heat generated during operation of the vibratory pile driver is radiated via the metallic gear housing to the environment. However, structure-borne noise is emitted to the environment via the gearbox housing. Such noise emission is undesirable, especially when working in an inner city area.

  • a basic idea of the invention is that the transmission housing to surround completely or at least in substantial parts of a Schalldämmgephaseuse.
  • the gear housing with the noise-generating imbalance units is mounted in the sound insulation housing via damping elements. As a result, a direct structure-borne noise transmission through the transmission housing to the surrounding air is largely prevented by the intended soundproofing housing.
  • the sound-absorbing housing is provided with a sound insulation layer.
  • the sound-absorbing housing may consist of a sheet metal, on the outside or preferably inside of the sound insulation layer is arranged.
  • the sound absorbing layer may preferably be a rubber material or a foam material having good sound insulating properties.
  • the mast can be designed as a leader or a boom.
  • damping elements comprise dampers made of a rubber material.
  • the transmission becomes directly from structure-borne noise of the Transmission housing further reduced to the soundproof housing.
  • the imbalance units are driven in rotation by a drive.
  • the at least one rotary drive is a hydraulic motor.
  • the hydraulic motor is arranged directly on or in the transmission housing.

  • the hydraulic motor is connected to a hydraulic fluid supply and a hydraulic fluid discharge to the carrier and the other hydraulic units.
  • hydraulic oil is provided as transmission oil for the transmission housing, with which also the rotary drive is operated.
  • the same oil is used both as hydraulic fluid and as transmission oil. This simplifies the supply of the corresponding hydraulic oil to the hydraulic motor and the transmission housing.
  • the hydraulic oil from the transmission housing and the hydraulic oil from the hydraulic motor is returned to a common hydraulic oil tank, which is arranged on the carrier device. After passing through the hydraulic drive, the hydraulic oil is substantially depressurized, so that it can be removed together with the hydraulic oil from the vibration generator to the carrier device.

  • the hydraulic oil tank is connected to a cooling device.
  • the cooling device may be an oil cooler with corresponding cooling fins, through which heat can be released to the environment. Basically also be provided an active cooling device.
  • the cooled hydraulic oil can be passed back to the hydraulic motor and in particular back to the transmission housing. This can be done via a shared or separate line.
  • the transmission oil is reduced via a corresponding throttle valve in its pressure, so that it can then be passed substantially without pressure in the transmission housing.
  • a further preferred embodiment of the invention consists in that the soundproofing housing has at least one closable access door.
  • the access door can be provided in particular in a front or lateral area, in particular to allow access to the hydraulic drives in the soundproofing housing.
  • the access door is also provided at least on the inside with a sound-absorbing coating.
  • the Schalldämmgephaseuse on its upper side an opening.
  • an opening in the upper area allows heat dissipation and thus a reliable prevention of heat build-up.
  • the sound-absorbing housing may in particular be configured like a trough, so that there is only one opening and thus an exit possibility of sound and heat at the top. In the area of the open upper side, oil lines can preferably run arcuately or bent, which improves heat dissipation.
  • the soundproofing housing has a guide device, with which the vibration generator is displaceably guided along the mast.
  • a linear guide is arranged, to which the guide means and in particular guide shoes correspond to the sound enclosure.

  • a holding unit for clamping and holding a pile is attached to an underside of the gear housing and that the sound-absorbing housing is spaced from the holding unit to form an annular gap which is covered by an elastic cover member.
  • the holding unit is in particular a collet, which is designed for clamping and vibration transmission for a sheet pile or other pile material to be excavated.
  • This holding unit is not in direct contact with the sound-absorbing housing. Rather, the holding unit is spaced over an annular gap of the Schalldämmgephaseuse. This gap is covered by an elastic cover, so that no direct sound radiation can take place from this gap.
  • the cover is designed as a bellows, which is attached on the one hand to the sound insulation housing and on the other hand to the holding unit.
  • the bellows has a certain flexibility, so that it can reliably follow the oscillating movements of the holding unit.

  • the quick coupling unit has corresponding coupling plug, which seal the oil lines leak-free when loosening the coupling unit.
  • the corresponding coupling counterparts of the quick coupling unit are arranged on a feed slide, which is movably mounted along the mast.
  • a further reduction of the sound radiation is achieved according to an embodiment variant of the invention in that at least one connecting device is provided with a support on the outside of the sound-absorbing housing, on which a damping lining is arranged.
  • the damping pad may be a rubber element or another foam or plastic element.
  • the Connecting device is preferably used as a support of a knob of a Rammgutommeskette on the collet. By Rammgutommeskette unintentional dropping a sheet pile from the holding unit is reliably prevented.
  • the connecting device may be provided with a quick release connecting element, such as screw or hook closures, or be part of the quick coupling unit.

  • the vibration generator 20 has an inner gear housing 22, in which two pairs of rotating unbalance units are mounted, which are driven by two lateral rotary drives 24 rotating.
  • the rotary actuators 24 are designed as hydraulic motors. Due to the rotating imbalance units, the transmission housing 22 is set in vibration.
  • the holding unit 50 has a stationary clamping jaw 52 and a clamping jaw 54 movable relative thereto, which is moved linearly by means of a lateral clamping cylinder 56 for clamping the sheet pile wall screed.
  • a connecting device 26 is arranged laterally on the stationary clamping jaw 52, which will be explained in more detail later.
  • the transmission housing 22 is largely enclosed by a sound-insulating housing 30.
  • the transmission housing 22 is connected to the outer Schalldämmgephase 30 via a plurality of damping elements 34, each having a damper 35 made of a rubber material.
  • the sound insulation housing 30 is formed from a metal sheet, on the inside of which a sound insulation layer 36 is arranged.
  • the transmission housing 22 can swing freely through the elastic mounting in the sound insulation housing 30 and transfer the vibration to the holding unit 50.
  • the holding unit 50 is spaced apart from the sound insulation housing 30 to form an annular gap 48. To avoid a sound radiation through the gap 48, this is covered by a flexible cover 46, which is designed as a bellows.
  • a removable access door 38 is provided on a front side of the soundproofing case 30 of the vibrator 20.
  • the vibration generator 20 is mounted on the sound insulation housing 30 slidably along the mast 14 via a clamp-like guide device 40.
