Definitions

  • the invention relates to a method for load-independent braking of the step or Pallet belt of an escalator or an escalator according to the generic part of the first claim.
  • the design of moving sidewalks causes the braking distance to be within the specified limits can be met.
  • the essential criteria for the design of the flywheel are in the case of escalators, the load caused by the number of people and, in the case of escalators, essentially the length in connection with the person load on it.
  • a disadvantage of the known brake is that the braking distance depends on the load done, no equal braking distances - because depending on the load - can be maintained, and that at certain constructional circumstances (e.g. excess length of moving walkways) Inertia masses are required that there are technical limits for the accommodation can be achieved. In addition, there is a relatively high degree of wear on the brake pads, what for safety reasons a continuous adjustment of the mechanical brakes makes necessary.
  • GB-A 2156173 relates to a method and a device for braking one Pedestrian conveyor system.
  • the movement of the passenger conveyor system should be in are braked essentially regardless of load and direction of travel.
  • To the A tachometer generator is used, which measures the delays, as a result of which the Driving current of the drive motor is changed.
  • On the turns of an AC drive motor direct current is conducted, which creates an electrodynamic braking effect so that a predetermined braking behavior of the engine Passenger conveyor system is induced.
  • EP-A 557 570 shows a braking device, preferably for a crane.
  • the same includes a drive motor and a brake, the motor being by means of Microprocessors is monitored.
  • a monitoring device checks the Microprocessor for possible braking problems.
  • an actuator provided that actuates the brake when a malfunction of the microprocessor is detected.
  • the object of the invention is to increase security and to comply with braking distances (downward and upward) as well as for Reduction of the mechanical effort (flywheels) on the one hand a different kind Braking method and the other one from St.d.T. deviating braking device too design that is no longer load-dependent and largely wear-free.
  • the goal is also determined by the in the characterizing part of the objective Achieved characteristics listed achieved.
  • the invention thus makes use of an exclusively electric one acting service brake.
  • the contacts of the main switching elements (Contactors) of the motor circuit for braking the escalator or moving walk kept closed, although by triggering one or more security elements the safety chain is broken.
  • all shutdown contacts in one current path act on two in particular contactors connected in parallel (redundancy), which both control the main switching elements cause during the frequency converter braking process as well in the event of deviations, ensure that the auxiliary brake is applied immediately.
  • An additional safety device can then ensure that the additional brake occurs after a time to be determined in any case (e.g. via two separate time relays). In the event that the timing relays and / or the monitoring contacts not working properly, an evaluation with an error message is made and start interlock.
  • the braking device also according to the invention can thus define the speed of the escalator or escalator brought to the value 0 m / s with essentially constant deceleration become.
  • the mechanical brake is applied as a holding brake.
  • the braking ramp of the frequency converter becomes activated and decelerated uniformly decelerated in compliance with the braking distance required in the relevant guidelines.
  • the immediate application of the auxiliary brake ensures that the Braking distance is maintained.
  • the deviation is the criterion for the premature idea pulled from the given ramp.
  • the evaluation is preferably carried out via a microprocessor in the electronic control of the escalator or the moving walk.
  • FIG. 1 shows the previous St.D.T. with electro-mechanical Shoe brake as a service brake and on the other hand the safety-related one Braking via frequency converter.
  • the speed is plotted over time.
  • Area a is the minimum defined in the applicable guidelines Braking distance, while b defines the maximum permissible braking distance.
  • the reference numbers 1 and 2 in connection with c define those working by means of the load dependent electro-mechanical brake achievable spread between minimum braking distance a and maximum braking distance b.
  • Reference number 3 indicates safety-related braking via frequency converters with / without load, with a defined braking distance over a predetermined time being always realizable in the case of load-independent braking (braking ramp).
  • the speed of the escalator or escalator is thus brought to a value of 0 m / s with constant deceleration.
  • the braking ramp of the frequency converter is activated and braked with a substantially uniform deceleration, while maintaining the required braking distance.
  • a standstill brake additional brake
  • Figure 3 shows a braking device substantially equivalent to Figure 2 with the Components drive motor 4, frequency converter 6, electrical or electronic Control 5, switch-off element 7 and brake magnet 8 and additional brake 9
  • security elements namely double mechanical / electrical Timers 19, 20 are provided, which in turn are connected via control lines 21 to the shutdown element 7 or the control line 22 with the electronic control 5 in operative connection stand.
  • These additional security elements ensure that that in the event of malfunction of the frequency converter 6 or the electronic control 5 and after reaching a standstill of the moving walkway not shown here the auxiliary brake 9 engages safely.
  • the braking ramp (3) shown in Figure 1 is constantly monitored for overshoot or undershoot.
