Definitions

  • the invention relates to a pneumatic door control system according to the preamble of the main claim.
  • Such door actuation systems are primarily used for the automatic closing and opening of doors in public transport, the closing process being initiated by the driver from the driver's seat (driver button) and the opening movement also by the driver or via push buttons or buttons (emergency taps) located near the doors by the passengers will. At the same time, the closing pressure of the closed doors is applied to lock them while driving.
  • both sides of the door actuation cylinder are depressurized by means of the emergency valve in order to be able to move the door without counterforce.
  • a force support preferably for opening the doors
  • FIG. 1 shows a door control system with a shuttle valve
  • FIG. 2 shows a door control system without a shuttle valve.
  • a door actuation system is connected to a pressure medium procurement device 1 consisting essentially of a compressor and a reservoir, which supplies the system with compressed air via a check valve 2.
  • an external emergency valve 5 In a supply line 4 leading from the check valve 2 to a door valve 3, an external emergency valve 5, a shut-off valve 6 and a throttle check valve 7 are arranged.
  • the emergency valve 5 is a manually operable two-position valve, and the shut-off valve 6 has three positions and is also manually operated.
  • a lock 8 is provided on the shut-off valve 6, with which the shut-off valve 6 can be locked in its central shut-off position.
  • the bolt 8 is provided with a bolt cylinder 9 for the pneumatic release of the bolt 8.
  • the door valve 3 is also designed as a two-position valve, in its one position a closing chamber 10 of a door cylinder 11 is connected to the supply line 4 and an opening chamber 12 to an outside air point 13. In the other position of the door valve 3, it is reversed.
  • a control cylinder 14 is attached to it, to which a control line 15 is guided.
  • a shuttle valve 16 is used, which has two connections 17 and 18 in addition to the outlet.
  • a closing pressure line 19 is connected so that the control cylinder 14 can be operated once with the closing pressure of the door cylinder 11 (emergency operation).
  • a line branch 20 leads to the other connection 18 and has a connection to the supply line 4, specifically to the system-side outlet of the check valve 2.
  • a 3/2-way valve 21, which can be actuated electromagnetically, is inserted, the circuit of which can be closed via a driver button 23. With the valve 21, the door valve 3 can be actuated normally via the shuttle valve 16.
  • a second emergency valve 22 is inserted into the closing pressure line 19, with which the closing pressure line 19 can be vented on the shuttle valve side.
  • the emergency valve 22 is activated.
  • the control cylinder 14 of the door valve 3 receives pressure via the then switching changeover valve 16, so that now the opening chamber 12 is pressurized from the supply line 4.
  • the closing chamber 10 is depressurized via the door valve 3, which is why the door valve 3 is not switched even when the emergency valve 22 is reset, because the control cylinder 14 is without pressure.
  • the shut-off valve 6 is used to depressurize the system when visiting a workshop for inspection purposes.
  • the shut-off valve 6 is provided with a bolt 8 which can be reset pneumatically via the locking cylinder 9.
  • the system is operated via the 3/2-way pilot valve 21, which pneumatically switches the door valve 3 via the shuttle valve 16 when the emergency valve 22 is in its drawn position.
  • This 3/2-way pilot valve 21 also puts the locking cylinder 9 under pressure so that the shut-off valve 6 reaches its starting position.
  • the use of the shuttle valve 16 ensures that the pneumatically actuated door valve 3 can normally be actuated via the 3/2-way pilot valve 21 and in emergency operation mode by valve 22, the emergency valve.
  • FIG. 2 shows a door actuation system similar to that shown in FIG. 1, corresponding parts therefore have the same reference numbers.
  • the shuttle valve 16 according to FIG. 1 has been omitted.
  • the closing pressure line 19 and the remaining line branch 20 of the control line are directly connected to the 3/2-way pilot valve 21, the closing pressure line 19 being connected to its venting point.
  • the pressure medium-effective switching of the door valve 14 takes place via the control line branch 20.
  • the control line branch 20 is vented via the 3/2-way pilot valve 21 and the closing pressure line 19 connected to its venting connection, as well as the venting connection of the emergency valve 22.
  • the emergency valve 22 is actuated, and the door valve 3 is then switched over with a pressure which is generated from the closing side 10 of the door cylinder 11, via the emergency valve 22 and the closing pressure line 19, and via the 3/2-way pilot valve 21 and the Control line branch 20 is brought up.
