Definitions

  • the invention relates to a method and a device for monitoring and / or controlling the speed of an electric drive with an asynchronous motor connected to an AC or three-phase network via a frequency converter and equipped with a braking device.
  • Hoists are mainly driven by inexpensive and maintenance-free three-phase asynchronous motors.
  • Asynchronous motors work on the three-phase network due to the network frequency of e.g. 50 Hertz in principle with a fixed nominal speed, from which only slight deviations are possible.
  • frequency converters are used between the three-phase network and the asynchronous motor.
  • Hoists and hoists must be built and dimensioned so that they can be operated safely and personal injury and property damage can be prevented by dangerous movements of the load.
  • the prior art includes a solution (EP 0 347 408 B1) in which frequency-dependent speeds can be set by field weakening via the frequency converter, so that heavy loads can be lifted at a slower speed and light loads can be lifted at the nominal speed.
  • frequency-dependent speeds can be set by field weakening via the frequency converter, so that heavy loads can be lifted at a slower speed and light loads can be lifted at the nominal speed.
  • the invention specified in claims 1 and 10 is therefore based on the problem of designing a hoist consisting of an asynchronous motor connected to a three-phase network via a frequency converter and equipped with a braking device for lifting and lowering.
  • the object is achieved according to the invention in that the maximum torque that the lifting drive generates for lifting a load is set to be smaller than the holding torque of the braking device. This ensures that an inadmissibly large and rapid lowering in such a way that there is a danger to people and things is avoided in any position of the load.
  • the available braking torque is increased by an addition to the maximum motor torque, which is necessary for a lowering movement of the maximum load at the nominal speed, in order to delay the lifted load to a standstill in a permissible time . This provides even more security against an impermissible acceleration of the load in lowering mode.
  • a speed control determines the maximum permissible frequency for the attached load by comparing the actual speed with the output frequency setpoint at a time when a follow-up contact of a command transmitter is actuated, which initiates the lifting movement by a first contact and by the latter Follow-up contact triggers the comparison process.
  • Safety is also increased in that the permissible speed limit values can be determined depending on the load at the start of the lifting process.
  • the frequency setpoint for an electric drive type point is first specified and the speed deviation measured and then a correspondingly larger maximum frequency is output to the frequency converter if the speed deviation falls below the nominal value.
  • this increases the performance of the engine through a higher speed exploited.
  • the electric drive type point is advantageously used because the behavior at this point is almost linear, which is an advantage of the asynchronous motor and involves a reproducible process.
  • the speed control device continuously monitors the deviation between speed and set frequency for the limit value typical of the electric drive during the stroke movements and activates the braking device as an emergency stop device when the limit value is exceeded. This creates additional security against subsequent loads of the hoist that have not yet been taken into account.
  • a further embodiment of the invention provides that an additional control signal is output by the command transmitter for stepless control of the frequency setpoint between the first contacts of the command device and the actuation of the subsequent contact. It is advantageous here that the operator can influence the speed directly via this command transmitter.
  • An additional control signal can be an analog signal, e.g. an electrical voltage.
  • Such an analog system can be processed advantageously in terms of control technology.
  • the size of the analog signal at the time of contact actuation of a first contact defines the minimum speed and the size of the analog signal at the time of actuation of the subsequent contact defines the maximum permissible speed or frequency, so that all speed or Frequency setpoints are specified within the permissible range.
  • a speed control device with a speed sensor on the electric drive is connected to a command device for the direction and speed of the lifting movement, with the frequency converter and the braking device, the speed control being the actual speed and the direction of rotation of the asynchronous motor and the Control command of the command generator for a desired stroke movement detected and from this the frequency setpoint for the frequency converter and a maximum permissible frequency setpoint.
  • the speed control device advantageously limits the frequency setpoint for the frequency converter to the maximum permissible frequency.
  • An asynchronous motor 1 drives (or brakes) via a gear 2 a cable drum 3, on the cable 4 a load 5 is suspended.
  • a tachometer 6a is connected to the asynchronous motor 1 in the form of a pulse generator 6, the pulses 7 of which arrive at a speed control device 9 via a first control line 8.
  • a brake 11 for the asynchronous motor 1 is connected to the speed control device 9 via a second control line 10.
  • a frequency converter 13 is connected between the AC network 12 and the speed control device 9 and contains an AC voltage part 13a, a DC voltage part 13b and a frequency converter part 13c.
  • a command transmitter 15 (manual control device) is connected to the speed control device 9 via a control cable 14. Switching devices 15a for "lifting the load” and 15b for "lowering the load” are located within the command transmitter 15.
  • a circuit part 15c for changing the voltage is also installed.
  • the brake device 11 has an electrically released brake.
  • the electrical brake ventilation takes place when the motor terminal voltage is switched on.
  • the pulse generator 6 generates an electrical signal corresponding to the engine speed "n".
  • the command generator 15 for the direction and speed of the lifting movement is connected to the frequency converter 13 and to the braking device 11 via the control cable 14 and the speed control device 9.
  • the speed control device 9 detects the actual speed and the direction of rotation of the asynchronous motor 1 and the control command of the command generator 15 for a desired lifting movement and forms the frequency setpoint for the frequency converter 13 and a maximum permissible frequency setpoint.
  • the method for monitoring and / or controlling the speed of an electric drive consisting of the asynchronous motor 1 with gear 2 and the cable drum 3, the asynchronous motor 1 being connected to the three-phase network 12 via the frequency converter 13, is performed by the braking device acting on the asynchronous motor 1 11 coined.
  • the maximum torque 16 of the lifting drive originating from the asynchronous motor 1, the transmission 2 and the cable drum 3, which the lifting drive generates for lifting the load 5, is set to be smaller than the holding torque 17 (FIG. 2).
  • the load is therefore always held securely when the direction of rotation is reversed.
  • a maximum permissible frequency for exceeding the nominal speed is determined if the maximum load is not reached.
  • the speed control device 9 determines the maximum permissible frequency for the attached load 5 by comparing the actual speed with the output frequency setpoint at a time when a follow-up contact of the command generator 15 is actuated. This initiates the lifting movement with a first contact and triggers the comparison process with its subsequent contact.
  • the braking device 11 is activated as an emergency stop device if the speed control device 9 continuously monitors the deviation between the speed and the desired frequency for the limit value typical of the electric drive and detects a limit value violation during the stroke movements.
  • an additional control signal can be output by the command transmitter 15.
  • an analog signal e.g. an electrical voltage.
  • the size of the analog signal at the time the contact is actuated by a first contact defines the minimum speed, and the size of the analog signal at the time the contact is actuated defines the maximum permissible speed or frequency.
  • the analog signal specifies all speed and frequency setpoints within the permissible range.
