Definitions

  • the invention relates to an elevator car with a braking device arranged in the region of the elevator car for holding and braking the elevator car, an elevator system with at least one such elevator car, and a method for holding and braking such an elevator car.
  • An elevator system essentially serves the vertical transport of goods or persons.
  • the elevator installation includes for this purpose one or more elevator cars, for receiving the goods or persons, which elevator car can be moved along a guideway.
  • the elevator installation is installed in a building and the elevator car transports goods or persons from and to different floors of this building.
  • the elevator installation is installed in a driving shaft of the building and, in addition to the elevator car, it contains suspension elements which connect the elevator car with a counterweight.
  • the guideway to guide the elevator car is often a guide rail, which is attached to the building, or in the chute.
  • each of the elevator cars advantageously has its own drive system, but advantageously uses the same guide track or guide rail.
  • Such elevator systems are equipped with braking systems, which on the one hand hold the elevator car in a floor stop and / or can decelerate and hold the elevator car in the event of a fault.
  • the braking system cooperates for the purpose of braking with a braking track, which is usually in the guide rail is integrated.
  • Such elevator system can of course be arranged outside the building, in which case the guide rails can be part of a scaffold.
  • Conventional safety gears are not designed to be able to hold the elevator car in a holding position, for example for loading the elevator car, since they can only be put into operation again by a service specialist.
  • a classic braking device for an elevator car is known in which an actuating device activates a braking device via levers.
  • a braking device to an elevator car is known, which is arranged in the region of the elevator car and which can be used for holding and braking.
  • the braking device shown there includes a fluidic brake unit which can cooperate with a brake rail, an actuating device which can actuate the brake unit and a connecting means which connects the brake unit with the brake unit in a force-active manner.
  • the actuating device is a hydraulic pressure station, which is connected via hydraulic connecting means to individual brake units and thereby force-actuated the hydraulic brake units.
  • Force-active here means that a generated in the actuator hydraulic pressure actively defines a resulting in the brake unit contact pressure of brake pads to the brake rail.
  • This solution uses hydraulic pressure generators. This is expensive and expensive in procurement and maintenance. Such components are also noise intensive and to limit the effects of leaks, safety precautions must be taken.
  • cabin brake devices are also increasingly used, for example, to hold an elevator car in a floor stop, during the loading process, or to quickly and smoothly correct erroneous behavior of the elevator car.
  • the object of the invention is now to provide a braking device, which quickly brought in an irregularity in the operation of an elevator car to use and after their use quickly back to their ready position can be brought.
  • the device should be quiet and easy to use.
  • An elevator car arranged in a driving shaft is equipped with a braking device for holding and braking the elevator car.
  • the braking device consists of a brake unit which, with appropriate operation, can cooperate with a brake rail.
  • the braking device further includes an actuating device, which can generate an actuator force FA, and a connecting means, which connects the actuating device for transmitting the actuator force FA force-actively with the brake unit.
  • a force-active connection means that the brake unit generates a contact force FN and thus ei-ne, resulting from a Bremsreibwert, resulting braking force, which is directly dependent on the Aktuatorkraft FA.
  • a small contact force FN thus causes a small braking force
  • a large actuator force FA causes a correspondingly large contact force FN.
  • the connecting means is now a traction means and the braking unit is designed such that it is in the unloaded position, i. if there is no actuator force FA in open position. Open position means the braking device, or, the brake unit does not brake.
  • pulling means advantageously a pull rope, a pull rod or a pull chain is used.
  • the advantage of this invention is that in an irregularity in the operation of an elevator car, the braking device by means of the mechanical connection means, or the traction means quickly brought into use and can be quickly brought back into their ready position after ih rem use.
  • the brake unit is designed such that it, when no Aktuatorkraft FA is present, in the open position, and the connecting means is carried out by the traction means, as a result of rapid and safe operation and Again, a slight provision can be made.
  • this device is very quiet, since during operation of the elevator system no pumps or the like must be in operation.
  • the device is easy to use because it can be easily checked and understood by a person skilled in the art. This arises already from the fact that the principle of this braking device has long been known and proven in bicycles.
  • this braking device is arranged in the area of the elevator car.
  • the braking device can be easily used to hold the elevator car in a floor or the braking device can in an unexpected behavior of the elevator car, if they are suddenly slipped away, for example, in the open floor access. Thanks to the simple operation, the braking device can be easilytechnischge sets.
  • the brake rail is a component of a guide rail on which the elevator car is guided along.
  • the location of the braking device is arbitrary. It can be built up or underneath the elevator car or below the elevator car, or it can be integrated in the elevator car structure, for example in a canopy, cabin floor or in side walls.
  • the elevator car according to the invention is installed in an elevator installation which may include one or more such elevator cars which can be moved in a common drive shaft.
  • an elevator installation which may include one or more such elevator cars which can be moved in a common drive shaft.
  • the braking device has at least two brake units, which advantageously at opposite boundary edges the elevator car are arranged and which cooperate with a respective brake, or guide rail.
  • the actuating device generates an actuator force FA for actuating the brake units (9), this actuator force FA being transmitted substantially symmetrically to the brake units by means of connecting means.
  • the actuating device is substantially centrally, is arranged in the middle between two brake units, wherein in each case a first connecting means to a first brake unit and a second connecting means is connected to a second brake unit.
  • This embodiment is advantageous because the holding and braking forces due to the two-sided arrangement of the brake units are introduced substantially symmetrically in the elevator car and the actuator can be centrally, for example, in the middle of a roof of the elevator car. This makes the control easy.
  • a position of the actuating device is essentially defined by a balance of the first and the second connecting means.
  • a limiting means is provided, which limits a lateral displacement of the actuating device in case of failure of one of the connecting means and thus maintains the actuator force FA in the remaining connecting means.
  • This increases the safety of the braking device, since a residual braking force remains despite failure of a connecting means. If, for example, the braking force of the braking device is designed with a safety factor of 2, holding would be ensured even if one of the connecting means fails.
  • the failure of one of the connecting means or contact of the limiting means by the actuator can be monitored with a switch and upon detection of this condition, a maintenance can be initialized or operation of the elevator system can be limited.
  • the brake unit includes a power transmission, which converts the actuator force FA transmitted by the connecting means into a contact pressure FN and at the same time effects a reinforcement of this contact force FN.
  • a power transmission which converts the actuator force FA transmitted by the connecting means into a contact pressure FN and at the same time effects a reinforcement of this contact force FN.
  • This is achieved, for example, by a lever mechanism which converts the actuator force FA into a contact force FN via a toggle lever, via eccentrics or else via dome disks.
  • With such translation or reinforcing means can be achieved large power gains.
  • This is advantageous because commercially available connecting means such as a Bowden cable can be used as a connecting means.
  • the actuating device is a Switzerlandspannvorraum used to generate the Aktuatorkraft FA.
  • the tensioning device when appropriately controlled, pulls or relieves the first and second connection means under control. This is done for example via a spindle gear, which attracts or relaxes one or both connecting means to the actuating device.
  • the spindle gear is designed such that the tensioning device retains its currently set position in the absence of a control signal or a supply energy.
  • the supply energy supplies the drive of the spindle gear or the actuating device with preferably electrical energy and the control signal is the control command to tension the connecting means or to relax the connecting means.
  • the advantages are to be seen in the fact that the braking force determination takes place centrally in the common actuating device and the actuator force is necessarily transmitted to the decentralized brake units with the same effect. In addition, it is ensured with the selected Glasspannvorraum that a set state is maintained.
  • the actuator force is essentially transmitted by train. This allows the use of favorable traction means such as a pull rope, a pull chain or a pull rod.
  • the actuator includes a sensor for fixing the current Aktuatorkraft FA and this sensor is optional for Control, regulation and monitoring used.
  • the sensor is, for example, a force measuring sensor or a spring-loaded position sensor, which detects a compression of a spring, via which the actuator force is transmitted, and accordingly, the position sensor is a measure of the Aktuatorkraft.
  • the position sensor for example, the positions of the actuator force are reached or the actuating device is adjusted, and the tensioning device is controlled on the basis of these signals.
  • actual force or pressure sensors can be used. The use of such a sensor is advantageous because a certain tensile force can be achieved independently of a state of wear and further, that any deviations can be detected and accordingly reported to a service station.
  • connection means with a pulley.
  • the actuator force FA transmitted by the connection means to the brake unit can thus be amplified in accordance with a pulley transfer factor. This makes it possible to achieve a holding or braking force required for a specific elevator installation.
  • An advantageous embodiment provides that several elevator cars according to the invention are installed, each with a braking device in a common driving shaft.
  • the braking devices of these elevator cars can be used not only to secure the elevator car in a floor stop but also to ensure a sufficient safety distance between several elevator cars. This is advantageous because it is possible to intervene quickly with the braking device if, for example, two elevator cars move toward each other at a small distance or if a distance between two successively moving elevator cars is reduced inadmissibly.
  • the braking device can quickly, or preventively, be brought into action and they can be reset after the elimination of the fault reason just as quickly.
  • the braking device can be mounted in addition to a safety gear on the elevator car. This is advantageous because it protects a known and safety-tested emergency brake system the elevator car against extreme errors, such as the failure of suspension elements, and the task of the braking device primarily for errors and / or use in areas of stops or in the vicinity of track limits, such as Fahrschachtende or another elevator car, can be aligned.
