Definitions

  • electromechanical actuator units In order to still be able to fall back on known and proven catching devices electromechanical actuator units are required, which can operate with appropriate control safety gears.
  • An elevator system is used to transport goods and people in buildings.
  • the elevator system includes at least one elevator car for receiving persons and goods, and usually a counterweight.
  • Counterweight and elevator car are connected to each other via one or more support means, such as a support cable, a carrying strap or other suspension means. These support means are guided over a deflection roller, or a drive pulley and the counterweight and the elevator car thus move against each other in the building, or in one in the building provided elevator shaft.
  • support means such as a support cable, a carrying strap or other suspension means.
  • These support means are guided over a deflection roller, or a drive pulley and the counterweight and the elevator car thus move against each other in the building, or in one in the building provided elevator shaft.
  • In order to prevent a crash of the cabin and occasionally the counterweight, or to prevent other misconduct of this car body - under the car is both the elevator car as well as the counterweight understood below - is at least the elevator car and occasionally the counterweight with a safety gear equipped.
  • each of the means for operating the safety gear is designed so that it alone is able to operate the coupled via the rotational axis of the driving body safety gear.
  • the safety of the elevator system is increased.
  • the two devices for the operation of the safety gear can be controlled together and they thus actuate the respective associated safety gear. If, for example, one of the two devices for actuating the safety gear fails, the remaining device is entirely capable of actuating both safety gears.
  • the driving body is by means of a pressure spring, preferably by means of a compression spring, to the elevator shaft, or to the guide or the brake rail, pressed and he is by means of an electromagnet in a standby position preserved.
  • a pressure spring preferably by means of a compression spring
  • the electromagnets are interconnected by two means for operating the safety gear in series. This additionally ensures that the triggering of arranged on both sides of the vehicle body safety gear takes place synchronously.
  • the solenoid can only relieve a delivery device, so that the driving body, for example, held by a spring from the elevator shaft, or from the guide or brake rail is kept distanced.
  • this guide pin In normal operation, this guide pin is held with a guide spring in the standby position, ie distanced from the elevator shaft or the guide or brake rail and de-energized state of the electromagnet, the anchor pin presses on the wedge slope of the guide pin together with the movable driving part against the elevator shaft, or the guide or brake track.
  • a speed sensor can be installed which measures a travel speed of the elevator and which automatically controls the device for actuating the safety gear when a critical travel speed is exceeded and thus actuates the safety gear.
  • the second device for the operation of the safety gear can be equipped with a counter pressure roller with speed sensor. In this way a redundant speed monitoring can be realized.
  • a further drive body for example a counterweight, contains a further device for actuating the safety gear as previously described.
  • this further drive body preferably includes a speed sensor, which is installed in the counter-pressure roller, as stated above, and it includes a power supply with energy storage, which is generated for example by means of revolving roller generator.
  • This device can then make a backup of this further driving body, without further electrical connections are necessary.
  • a status signal can be transmitted via a wireless connection.
  • a suspension or balancing cable between the cars usually between the car and the counterweight, can be used to transmit the required signals and energy. In this case, if necessary, of course, the speed, and the safety information processed in one of the cars and then transferred to the other drive body.
  • the catching device is an eccentric catching device.
  • Exzenterfangvoriques is for example from the disclosure DE2139056 known.
  • the device for the operation of the safety gear can be connected by means of the connecting rod to the eccentric Exzenterfangvorraum and thus a direct operation of such a safety gear is guaranteed.
  • required dimensions of the device for the operation of the safety gear must be adapted to the requirements of the safety gear. If the safety gear is designed for actuation in both traversing directions, the device for actuating the safety gear can, if required, also be geared to a double-sided actuation.
  • the counterweight is equipped with safety gear, which are operated only in case of a missing suspension force, by means of a slack rope monitoring, or slack rope release.
  • the catching device is actuated on the counterweight only in the case of a suspension of the suspension force on the counterweight, which is the case, for example, in the event of a suspension element failure.
  • the slack rope monitoring is provided with a damping element, such as a pneumatic damper.
  • the elevator car 3 is equipped with a safety gear 11 which is suitable for securing and / or decelerating the elevator car 3 in the event of unexpected movement, overspeeding or stopping.
  • the safety gear 11 is arranged below the elevator car 3 in the example.
  • the safety gear 11 is electrically controlled and it is connected to a device for the actuation of the safety gear 18.
  • a safety device 41 and optionally a monitoring device 42 is present.
  • the safety device 41 is connected to sensors.
  • Such a sensor is for example a speed sensor 40.
  • the speed sensor 40 may be a tachogenerator or an incremental encoder, which are integrated, for example, in one or more guide rollers or in deflection rollers.
  • the monitoring device 42 monitors, for example, the elevator car at a standstill when the elevator car is for the purpose of unloading or loading in a floor.
  • the feed device 43 is executed in the example as part of the connection axis 23.
  • Fig. 9a and 9b The function of this feed device 43 is now explained in particular.
  • the figures show a horizontal section through the connection axis 23, which contains such a feed device 43 in the end region, advantageously in both end regions.
  • Fig. 9a is between the braking surface of the guide rail 9 and the driving body 20, an air gap. This corresponds to the ready position of the device for operating the safety gear as in Fig. 4 explained and illustrated.
  • the fixed driving part 20.1 is arranged on the connecting element 23.1 of the connecting shaft 23. In this fixed driving part 20.1 of the movable driving part 20.2 is held by a guide pin 35.
