Definitions

  • the invention relates according to the preamble of claim 1 a frequency converter for an internal vibrator.
  • Internal vibrators are used to compact still liquid concrete.
  • a belonging to the internal vibrator vibrating bottle is immersed in the concrete, in which an electric motor and driven by this at high speed unbalance are housed.
  • the motor To achieve the required motor speed and thus the compression frequency, the motor must be supplied with a special voltage whose frequency (eg 200 Hz) is above the mains frequency provided by the public grid.
  • the special voltage is provided by a special voltage network or by a frequency converter, which is provided either on site in the form of a larger stationary unit or as an integral part of the internal vibrator.
  • An internal vibrator with integrated frequency converter is from the DE G 92 17 854.5 known.
  • the invention has for its object to provide a frequency converter, which also makes it possible for internal vibrators without their own integrated frequency converter, if desired, to take advantage of internal vibrators with its own frequency converter.
  • a frequency converter according to the invention has a mobile converter housing with a converter circuit and is characterized in that a socket supplied by the converter circuit with the special voltage is provided on which a plug part of the internal vibrator can be inserted.
  • a known, not own frequency converter having internal vibrator with its serving as a plug-in power plug plugged into the socket of the frequency converter, wherein the socket can be integrated into the converter housing or connected via a further supply line to the converter housing.
  • An advantageous embodiment of the invention is characterized in that the socket is fed alternatively to the special voltage with mains voltage and that a switch is provided for switching between special and network voltage.
  • the internal vibrator can also - as before - be connected to a special voltage network without the frequency converter would have to be reduced by him. This has the advantage that the frequency converter can not be lost in busy construction site operation.
  • a securing device is provided in the region of the socket, with which the plug part of the internal vibrator is held in the socket.
  • the safety device thus serves as a train protection and allows the operator to drag the frequency converter on the internal vibrator behind him.
  • this has the converter housing on an elongated outer shape with minimized transverse dimensions, which greatly facilitates the hatchability of the converter housing on the usually provided with numerous reinforcing iron construction site.
  • a smooth outer skin of the converter housing further improves the mobile handling of the frequency converter.
  • FIGURE shows a frequency converter according to the invention with connected internal vibrator.
  • An internal vibrator 1 known per se has a vibrating bottle 2, in which an elongate electric motor and an unbalance driven by the electric motor are accommodated.
  • the vibrating bottle 2 is connected to a switch housing 4 via a protective hose 3 that is up to several meters long.
  • the protective tube 3 also serves as a service hose, with which the vibrating bottle 2 is dammed by the operator in the concrete to be compacted.
  • a switch 5 is arranged, with which the electric motor in the vibrating bottle 2 can be switched on and off. From the switch housing 4, an electrical lead 6 is led out, which opens into a power plug 7.
  • known per se internal vibrator 1 is connected to the power plug 7 in a present at the site special voltage network or a stationary frequency converter.
  • a frequency converter 8 is provided in which the mains plug 7 is inserted.
  • the frequency converter 8 has a converter housing 9, in which a known electronic converter circuit is housed. Furthermore, an additional switch may be provided, with which the power supply can be interrupted.
  • a supply line 10 is led to a power plug 11.
  • the power plug 11 can be plugged into a conventional, existing on the site public network.
  • a socket 12 is integrated in the converter housing 9, in which the plug 7 of the internal vibrator 1 can be inserted.
  • the frequency converter 8 receives via the power plug 11 usual mains voltage (230 V or 400 V, 50 Hz), which is guided via the supply line 10 to the converter circuit in the converter housing 9. There, the mains voltage is converted to a special voltage, the z. B. 42 V can be 200 Hz. The special voltage is applied to the socket 12, where it can get over the power plug 7 in the internal vibrator 1.
  • mains voltage 230 V or 400 V, 50 Hz
  • the socket 12 it is also possible to arrange the socket 12 away from the converter housing 9 and to connect it to the converter housing 9 by means of an additional supply line.
  • the converter housing 9 has an elongated, slender outer shape with minimized transverse dimensions and a smooth outer skin in order to be able to be pulled through concrete reinforcements without resistance. Slanted end walls 13 on the converter housing 9 still support the hatchability.
  • the frequency converter 8 can be particularly easy to handle mobile. The handling is still supported if the converter housing 9 carries no handle that could affect the hatchability.
  • another embodiment of the invention makes it possible that the socket 12 can be fed not only with the special voltage, but optionally also with mains voltage.
  • a changeover switch for switching between special and mains voltage is provided on the converter housing 9. While the current for generating the special voltage is passed through the converter circuit, it is performed after actuation of the switch directly from the supply line 10 to the socket 12, that is only passed through the frequency converter 8. This makes it possible, at least for a short time, to connect the combination of internal vibrator 1 and frequency converter 8 to existing special voltage networks without the internal vibrator 1 having to be disconnected from the frequency converter 8.
