Definitions

  • the invention is based on a pneumatic door control system according to the preamble of the main claim.
  • Such door actuation systems are primarily used for automatically closing and opening the doors in public transport, the closing process being initiated by the driver from the driver's station and the opening movement likewise by the driver or via push buttons or buttons arranged near the doors by the passengers. At the same time, the closing pressure of the closed doors is applied to lock them while driving.
  • the invention is based on the object; to improve a circuit arrangement of the type mentioned in such a way that, with little effort, a risk to persons even when the doors open is safely excluded and the known design is simplified.
  • Such a door operating system has the advantage that protection against jamming in the opening and closing directions is provided not only during normal operation of the system but also in the event of electrical failure or in workshop operation, i.e. if the door valve switched mechanically by hand when the system is intact is activated by a magnet is.
  • the secondary ventilation regardless of the pressure level in the door cylinder during the movement of the door, ensures a constant, previously adjustable and safe clamping force for the passenger.
  • Another advantage is that the triggering force on the differential pressure switch can be selected completely independently of the setting of the pressure limiter. This makes it possible, for example, to set the clamping force so low that the doors run slowly and without beating into their end position after an obstacle has been removed.
  • the speed at which the door moves is not affected by the pressure limiter, because the pressure limiter is under current during normal operation of the door and therefore assumes a position in which the compressed air passage through the pressure limiter is unimpeded, that is to say free.
  • FIG. 1 shows a first embodiment of a door actuation system with a lockable emergency valve
  • FIG. 2 shows a modification of the type according to FIG. 1 with an unlockable emergency valve
  • FIG. 3 shows an electrical switching device for the systems according to FIGS. 1 and 2.
  • a door operating system has a storage container 2 fed by a compressor 1, to which two double-acting working cylinders 4, 5 are connected via a line 6, 6a via an electromagnetically actuated switchover or door valve 3.
  • Each working cylinder 4 and 5 is intended for actuating a door, not shown, which is articulated to it.
  • Each closing side of each working cylinder 4 and 5 is a throttle 7 or 8 and each opening side is a throttle check valve 9 or 10 upstream.
  • an emergency valve 11 This is designed as a 3/3-way valve, has a manual override 12 and also a lock 13. The middle position, in which all line connections are separated, is only a transitional position. Subsequent to the emergency valve 11, a throttle valve 14 (also called a starting throttle) is inserted into the line 6, and a pressure limiter 15 is located in front of the door valve 3 neten position the pressure limitation is effective.
  • the pressure limiter 15 has a ventilation point 16 which, in this position of the pressure limiter 15, is connected to the secondary side of the system, that is to say to the working cylinder side. Via this vent 16, the pressure of the secondary side can be released to a certain residual pressure. In its current-operated, other position, it offers a free, unobstructed passage through line 6.
  • the door In the drawn position, the door is closed. To open the closed door (s), the door valve 3 is switched over by briefly receiving its magnet. Before d. H. As soon as the vehicle's electrical system was switched on, the pressure limiter 15 had been switched to its other position, in which it did not hinder the passage of air. The door is opened and the other side of the working cylinder 4 or 5 is vented. If a person is pinched when opening, the power supply to the pressure limiter 15 is interrupted by one of the differential pressure switch 23, which measures the differential pressure between the opening and closing chamber of the working cylinder and responds when a predetermined value is exceeded, so that the pressure limitation becomes effective and the secondary side is vented is up to an adjustable residual pressure.
  • the opening force of the door is significantly reduced and the trapped person cannot be harmed.
  • the door runs slowly and without beating into its open end position due to the low residual pressure.
  • the pressure limiter is energized again by the electrical switching device described in FIG. 3, so that the system is normally ready for operation again at full supply pressure.
  • the door valve 3 is switched over again. If a person is trapped when the door is closed, the reversing which is customary in this case is brought about by means not shown in FIG. 1. With the emergency valve 11, the system can be depressurized so that the doors can be easily opened or closed by hand.
  • the lock 13 ensures that after resetting the emergency valve z. B. during a repair of the vehicle, the system can only be put back into operation by actuating the actuating device located in the driver's position.
  • FIG. 2 shows that it is also possible to do without a lock 13 if the structure of the system is otherwise the same by using the pressure limiter 15 according to the invention. This is because the pinch protection is fully effective even when the system is de-energized by the pressure limiter 15 according to the invention.
  • FIG. 3 shows an embodiment which, starting from the installation according to FIG. 1, represents the electrical circuit for the installation. Corresponding parts again have the same reference numbers as in FIG. 1.
  • the pressure limiter 15 there is a normally closed relay 22, the one coil side of which is connected to + and the other coil side of which is connected to ground via the differential pressure switch 23 and a limit switch 24, but only if the differential pressure switch 23 is closed. So, as shown, the relay 22 is de-energized, but the pressure limiter 15 is energized.
  • the limit switches 24 are mechanically operated switches which are actuated by the door in the settings thereof.
  • Another relay 25 is - as drawn - open when de-energized and controls the current for the pressure limiter 15 in connection with the other relay 22.
  • the mode of operation is such that after the occurrence of an obstacle in the door movement path the pressure limiter 15 is switched to its pressure limiting position.
  • the relay 25 represents a holding relay circuit that comes into operation when the contact of the differential pressure switch 23 closes.
  • the holding relay circuit is released when the door reaches its end positions and the limit switch 24 disconnects the circuit.
