Definitions

  • the invention refers to a vibrating device for concrete compacting of the type which have an electrical motor operated by a switch and powered by a converter, and specifically the type in which the converter is combined with the switch to form a miniaturized unit.
  • Patent document EP-A-0604723 describes an internal vibrator for concrete compacting, with an electrical motor powered by a converter and with a switch for its connection and disconnection.
  • the converter and switch are adapted to form a miniaturized control unit located in an area relatively near to the vibrating rig.
  • the vibrating device and especially the frequency shifter that is near the vibrating head, is permanently submitted to harsh treatment which usually involves that said element suffers knocks and other violent effects, with the consequent risk of breaking;
  • another inconvenience presented by the previously described vibrating devices is the difficulty to handle them due to their elevated weight and substantial size as was explained before, factors that have a great importance during the maneuvers of introducing and extracting the vibrator from the casing, since in addition to the difficulty that the operator has to find an adequate work position there is the weight and volume of the control unit, which greatly hinders the execution of the work.
  • the vibrating device for concrete compacting object of the present invention comprises a frequency shifter unit, which converts single phase power into three phase power, a control unit with a switch to turn on the device and stop it, and a vibrating head, as well as a plug in order to be plugged into an electrical socket, a flexible and isolated electrical cord, for connection to the electrical network, which links said plug with the frequency shifter unit, and an immersion area right next to the vibrating head, consisting of isolated electrical conductors having a flexible, tubular protective covering, usually made of a tube of rubber or an equivalent material.
  • the vibrating device for concrete compacting is characterized in that the frequency shifting unit and the control unit are arranged independent from each other and connected by a long multiple-pole electrical cable, with the frequency shifting unit being located in a relatively close position to the plug, and the control unit being located between the mentioned long multiple-pole electrical cable and the beginning of the immersion area.
  • the frequency shifter unit is capable of generating variable frequencies, adjustable at will, in order to suit the mass of concrete that is desired to be vibrated.
  • the switch of the control unit can be activated and deactivated exclusively be direct manual activating means.
  • the control unit has radio frequency and/or infrared sensor elements adapted to act upon the switch intended for starting or stopping the motor located in the vibrating head, commanded by means of a remote control unit.
  • control unit has, aside from the remote control, means of direct manual activation.
  • the control unit only weighs between 0.400 and 0.800 kg, since the frequency shifting unit, which is independent, is supported on a surface, usually the floor.
  • this is a logical consequence derived from the mentioned reduction of weight.
  • the harsh treatment there is no doubt that there is a very significant reduction of the knocks and other possible harmful treatments suffered by the frequency shifting unit since it is not permanently united to the user's handling, but to the contrary it is supported on a surface away from the operating area; a positive consequence is that a greater operating time without damages to the vibrating device is attained.
  • the vibrating device 1 for concrete compacting object of the invention three main elements can be distinguished, a vibrating head 2, a control unit 3, and a frequency shifting unit 4.
  • the plug 5 On one of the ends of the vibrating device 1 the plug 5 is positioned which is adapted for being connected to an electrical socket of a 220-240 V/50 Hz network in the case of Europe, and 115 V/60 Hz in the case of the United States of America, in either of the two cases, single phase alternating current networks.
  • the plug 5 and the frequency shifting unit 4 are united to each other by a relatively reduced length, of approximately 2 meters, of flexible and isolated electrical cable 6, for connection to the electrical network, which comprises two active conductors and one for protection.
  • the frequency shifting unit 4 comprises a box 7 of rectangular parallelepiped shape in the interior of which is housed an electronic frequency shifter 8 and a safety device, mainly consisting of a fuse box 9 adapted to prevent short circuits and to prevent grounding discharges.
  • the electronic frequency shifter 8 is capable of generating variable frequencies at will between approximately 150 and 300 Hz in order to adapt to a greater or smaller mass of concrete that is desired to be vibrated.
  • the frequency shifting unit 4 and the control unit 3 are united by means of a minimum of approximately 10 meters, and preferably of 15 meters, of multiple-pole electrical cable 12 of five active conductors and one of protection, flexible and isolated, to ensure the adequate operation of the vibrating device.
  • control unit 3 The connection of the control unit 3 with the multiple-pole electrical cable 12 is protected and secured with a stuffing box 13 to isolate the interior of said control unit 3 from aggressive external agents.
  • a main electrical switch 14 is positioned to start or stop the motor 15 located in the vibrating head 2.
  • Figures 3, 4 and 5 each represent a different form of embodiment in what concerns the way of starting or stopping the vibrating device 1.
  • the main switch 14 located inside the control unit 13 is activated manually by means of the button 16 for manual operation.
  • the operator who is using the vibrating device 1 according to the invention cares for starting and stopping it acting directly upon the button 16.
  • the main switch 14 is linked to an electronic sensor element 17 for connection and disconnection, capable of receiving a signal of radio frequency, infrared ray, ultrasound, or any other adequate known system, which is emitted from a remote control unit 24, in order that it can activate or stop the motor 15 located in the vibrating head 2 from a certain distance. Therefore, it is not necessary that the operator who is using the vibrating device 1 be the same person who starts it and/or stops it.
  • Figure 5 another alternative has been drawn consisting in combining the two possibilities explained in Figures 3 and 4.
  • the control unit 3 is equipped with a manual activation button 16 and also an electronic sensor element 17 for connection and disconnection which is sensitive to the signals emitted from a remote control unit 24, in a similar manner to what has been explained above when describing Figure 4.
  • Both the manual activation button 16 as well as the electronic sensor element 17 act upon the main electric switch 14.
  • This embodiment of Figure 5 is the most complete and it allows to enjoy the advantages of the two types of activation: the direct manual activation, and the activation from a distance with the assistance of a remote control unit 24.
  • FIG. 6 represents in detail the vibrating head 2.
  • the control unit 3 and the vibrating head 2 are united by isolated electrical conductors 18 (3 active conductors and a protection conductor) of three phase alternating current.
  • the electrical conductors 18 are covered with a protective tubular covering 19 of flexible material, generally of rubber or an equivalent material, which can be submerged inside the mass of concrete.
  • the vibrating head 2 located at the end of the vibrating device 1 basically has an elongated cylindrical shape with a conical end, and it is art which is well known.
  • the electrical motor 15 Housed in the main part of the inside of the vibrating head 2 is the electrical motor 15 of variable frequency between approximately 150 and 300 Hz.
  • variable frequency motor Arranged at the end of the axis of the mentioned variable frequency motor are some balance weights 20, 21 and some bearings 22 which produce a vibration for each turn of the motor 15.
