Definitions

  • the invention relates to an electric hoist with speed-controlled lifting speed, in particular an electric chain hoist, in which an electric motor, a transmission, a wheel wrapped by the traction means, the traction means and a load-carrying means are connected to one another in terms of drive, with an electric control for the electric motor, which is connected to a manual control switch is.
  • Such electric chain hoists are hoists driven by an electric motor, which use a link chain as a suspension element and are mainly used for the vertical transport of loads.
  • the electrical energy from the power supply for the motor is switched directly or is controlled via contactors (motor switch).
  • the electrical control in addition to the manual control switch, the electrical control includes a corresponding number of motor switching pairs which are installed in a protected manner on the chain hoist.
  • Electric (chain) trains generally have a single speed for lifting and lowering the load according to the nominal speed of the motor and the gear ratio selected. For special applications, a second slower speed is required. In these cases, a pole-changing motor is selected that has an additional winding for the second motor speed and is switched with additional switches of the electrical control.
  • the frequency converter control replaces the aforementioned electromechanical motor switches.
  • the present invention is therefore based on the object of constructing an electric (chain) train with speed-controlled lifting speed in such a way that an installation of control electronics and a tachometer is simple and space-saving possible and the heat loss can be dissipated sufficiently.
  • the stated object is achieved according to the invention due to the electric train with speed-controlled lifting speed described in the introduction in that the electrical control, which has control electronics with a speed sensor system, is arranged in an external protective housing placed on the gearbox. This makes it possible to install the control electronics and the speed sensor system easily and in a space-saving manner and at the same time dissipate the heat loss sufficiently.
  • the protective housing has the shape of a cup-shaped hood. This provides the required space, because the protective housing adapts ideally to the other housing components, so that a compact unit is created.
  • cup-shaped hood consists of a good heat-conducting material. This promotes heat dissipation.
  • the desired heat dissipation can advantageously be promoted by attaching a carrier for power semiconductors of a frequency converter that generates heat loss to the inside of the pot base.
  • a shaft end of the transmission or the electric motor protrudes in a lower case between the protective housing and the transmission case, on which a pulse wheel of the sensor system is fixedly arranged.
  • the pulse wheel can rotate at the engine speed or at a slightly reduced speed and e.g. consist of a magnetic ring and a corresponding number of north and south poles for a magnetic sensor or a reticle for an optical sensor.
  • This arrangement can be carried out in such a way that the scanning unit of the sensor system is fastened on the circuit board which can be swiveled out and the pulse wheel on the opposite side on the transmission or motor shaft.
  • the housing of the compact unit of the electric train which is closed with regard to the required dust protection, can now be further cooled to the extent that a fan wheel is rotatably arranged on the shaft end of the electric motor opposite the shaft end of the sensor system and that the protective housing, the lower box, the Gear box and the electric motor housing each closed from the outside, forming interconnected interiors inside.
  • the cooling air flow of the fan wheel is therefore guided through the electric motor, the gearbox, the sensor system to the converter unit and exits the protective housing there.
  • the components for processing the control command from the manual control switch, the speed detection, the speed control of the electric motor and the control of the frequency converter are arranged on the circuit board.
  • the frequency converter installed in the protective housing is connected to the power network, the electric motor and the printed circuit board via cable connections.
  • seals are inserted between the protective housing and the lower box, as well as around a cable duct. This ensures the protection of the frequency converter, the speed sensor system, the gearbox, the electric motor and other components.
  • An electrical control 7, which consists of control electronics 7 a, which is operated by means of a manual control switch 26, is used for speed control and thus for controlling the lifting speed.
  • the electrical control 7 in the form of the control electronics 7a has a speed sensor system 8 with a pulse wheel 8a, which in the example of FIG. 2 is arranged on a gear or motor shaft 17 and also has a scanning unit 8b.
  • the pulse wheel 8a consists e.g. from a rotating magnetic ring with a corresponding number of north and south poles for a magnetic sensor or from a reticle for an optical sensor.
  • the speed sensor system 8 is arranged together with the control electronics 7a in a protective housing 10 which adjoins a gearbox 9 and is accordingly conveniently accessible for cooling.
  • the protective housing 10 which is on the outside, has the shape of a cup-shaped hood 10a.
  • the cooling can e.g. be built up by a good heat-conducting material, by cooling slots, that is to say on the principle of heat flow and / or heat conduction.
  • a carrier 12 for power semiconductors 13 of a frequency converter 14 which generates heat loss is advantageously accommodated on an inside 11 of the pot base 10b.
  • the inside 11 of the protective housing 10 is provided with a black surface 15 to improve the heat transfer.
  • a shaft end 17a of the transmission 3 or the electric motor 2 projects into a lower box 16 between the protective housing 10 and the transmission box 9.
  • a pulse wheel 8a of the sensor system 8 is arranged in a rotationally fixed manner.
  • An electronic circuit board 19 is installed in the lower box 16. After the protective housing 10 has been removed, this printed circuit board 19 can be pivoted outwards by a hinge 20 (after loosening opposite screws) for the purpose improved accessibility and access to the impulse wheel 8a.
  • An arrangement of the sensor system 8 is provided such that the scanning unit 8b of the sensor system 8 is fastened on the circuit board 19 which can be swiveled out and the pulse wheel 8a opposite on the transmission or motor shaft 17th
  • the cooling can also be carried out by circulating cooling air.
  • a fan wheel 23 is rotatably arranged on a shaft end 17b of the electric motor 2 opposite the shaft end 17a.
  • the cooling air flow of the fan wheel 23 is guided through interior 24a of the electric motor 2 and 24b of the gearbox 9 and 24c of the lower case 16 or of the protective housing 10, which are connected to one another in the interior and are closed to the outside, cooling air slots (not shown in more detail) being attached to the end of the protective housing 10 .
  • components 25 for processing the control command from the manual control switch 26 (FIG. 2), the speed detection, the speed control of the electric motor 2 and for the control of the frequency converter 14 are arranged in the protective housing 10 on the printed circuit board 19.
  • the frequency converter 14 installed in the protective housing 10 is connected to the power supply system, the electric motor 2 and the printed circuit board 19 via line connections 27. Seals 29 are inserted between the protective housing 10 and the lower box 16 and around the line bushing 28.
