Definitions

  • the present invention relates to an elevator installation with a braking device and a method for braking and holding an elevator installation according to the definition of the independent claims.
  • An elevator installation includes an elevator cage which moves in the vertical direction within guideways or guide rails.
  • the elevator car is braked in case of need by a braking device or held at a standstill.
  • a braking force is required.
  • the braking device used for this purpose usually at least two brake units which press in the request case at least one brake pad against a counter surface. This pressing takes place by means of a normal force.
  • the braking force of a brake pad is determined by the normal force together with the coefficient of friction defined by the brake lining, the mating surface and any intermediate layers.
  • the counter surface is usually defined by an area of the guideway or the guide rail.
  • DE 3934492 shows a braking device for an elevator car which engages in the brake case on the guide rail, wherein the braking force is controlled by means of an acceleration sensor.
  • the braking force is applied by a spring, with a controllable magnet, the braking force can be reduced at a too high delay value or can be amplified at too low a delay.
  • a disadvantage of this device is that the braking device is not designed to hold an elevator car in a stop position, such as a regular stop on a floor.
  • the braking device is on set a fixed predetermined by the spring value, which is approached either as quickly as possible in the case of work, which thus can lead to a significant transient process, or which is slowly approached in case of work, controlled by the opposing force of the solenoid, resulting in the speed at a full loaded cabin unfavorably increased.
  • the variable magnet is expensive and heavy, it also takes on a high performance and monitoring the operational readiness of the device is difficult to carry out.
  • the power requirement is high because the maximum possible braking force to be applied by the braking device is aligned with a freely falling, fully loaded car. As a rule, however, for example during braking from overspeed, an unladen or only to a small extent loaded cabin is braked. Here, only small braking forces are required.
  • the weight of a corresponding stroke / shock magnet is up to 50 kg, or for two magnets up to 100kg.
  • US5323878 discloses another braking device with two brake units.
  • the brake units are arranged in the region of a drive machine.
  • the braking forces are transmitted via support members of the prime mover to the cabin.
  • the braking force of each brake unit is set by a brake control unit in consideration of the car speed or car load.
  • the braking force is generated by means of a spring, wherein a hydraulic piston force counteracts this spring.
  • This design corresponds to today's conventional, safer design, as in a failure of the hydraulic brake the springs with their maximum possible force.
  • the required hydraulic piston force of each brake is calculated and hydraulically controlled by a brake control unit taking into account the car speed or cabin load.
  • the hydraulic piston force must be determined taking into account brake-specific properties, such as piston diameter, spring force or mounting geometry of each brake unit.
  • a disadvantage of this device is that relevant influencing factors which influence the braking force are not recognized and not taken into account.
  • a failure of a spring, wear of a brake lining or jamming of brake levers can lead to a relevant influence on the braking force, which is not recognized.
  • the brake control unit must take into account brake-specific properties, such as piston diameter, spring force or mounting geometry, of each brake unit, since the brake control unit specifies the hydraulic piston force for each individual brake unit.
  • the object of the present invention is accordingly to provide a controllable braking device and a method for braking and holding an elevator installation, which allows a delay or hold corresponding to the operating state of the elevator installation and which responds quickly and gently.
  • the braking device must also meet high safety requirements and they should be able to operate with low power and have little additional weight.
  • the error rate of the braking device should also be low.
  • each brake unit includes a normal force control which regulates an effective normal force corresponding to a target normal force value determined by a brake control unit and / or each brake unit includes a locking device which can lock the brake unit in a set braking position corresponding to a set effective normal force.
  • each brake unit has its own normal force control, which regulates an effective normal force corresponding to a desired normal force, so that each brake unit can be assigned its own nominal normal force.
  • the brake unit itself can thus set a normal force quickly and accurately and it can thus correct deviations in the areas of the brake unit, such as geometric deviations (for example, wear of a brake plate or different dimensions of brake rails) by a control process automatically.
  • An error rate of the entire braking device is significantly reduced.
  • a replacement of a brake unit is easily possible because the brake-specific properties, such as piston diameter, spring force, mounting geometry or other design-related data, the brake unit in the brake unit itself are taken into account and thus complex and error-prone inputs of these brake-specific properties account for the brake control unit.
  • the braking force requirement results from a Operating state of the elevator system such as a payload, a vehicle speed, a location in the elevator shaft, an acceleration value or other state variables of the elevator car, or the elevator installation. This allows a particularly gentle braking of the elevator system.
  • a set braking position can be locked. In this case, a set effective normal force is locked. This allows holding or braking the elevator car without additional power.
  • An elevator installation 1 consists at least of an elevator car 2 and an elevator drive 10 Fig. 1 requires an exemplary elevator installation 1 in the further support means 11 and a counterweight 12 wherein the elevator drive 10, the support means 11 drives and thus the elevator car 2 and the counterweight 12 moves against the same.
  • the elevator system 1 requires at least one braking device 13.

  • These different load cases require different braking or holding forces F B.
  • Fig. 2 shows a variant of a braking device 13, which consists of a brake control unit 15 with power supply 43 and - in the example shown - from four functionally identical brake units 14.
  • Functionally identical means that the brake units have the same functional structure, but may well be different according to their geometric dimensions.
  • Each brake unit 14 has a brake force measurement 36, 37.
  • the power supply 43 supplies the brake control unit 15 and the brake units 14 with a safe voltage U B. Elevator control 5 and measuring sensors 20,21,22,23 provide the brake control unit 15 required elevator signals.
  • the brake control unit 15 supplies the individual brake units 14 with individual desired specifications S B1... I. 1 to i is in Fig. 2 for the individual brake units 14.
  • a target specifications S Bi is, for example, a desired normal force F N-soll or a desired air gap 30. These target values S Bi are transferred to the associated brake unit.
  • the brake unit 14 processes this setpoint in its own control blocks 16, 28 F N , S N , which work with known control technologies.
  • the brake units 14 in turn deliver effective state variables Z B1... I to the brake control unit 15.
  • Effective state variables Z B1 ... i can again be an effective normal force F is N-eff or a real air gap 30.
  • each brake unit 14 has a brake force measurement 36, 37, which determines an effective braking force F B1... I and transmits this value to the brake control unit 15.
  • the brake control unit 15 further has a safety module 44 in the illustrated example .
  • the inventive braking device 13 is provided for the previously mentioned different load cases.
  • the braking device 13 is as in Fig. 1 and Fig. 2 represented by at least two brake units 14 and each brake unit 14 includes a normal force control 16, this normal force control 16 an effective normal force F N-eff in the brake unit 14 according to a target specification S Bi , the target normal force F N-soll controls, which of a brake control unit 15 is given.
  • This normal force control 16 is that the brake unit itself can quickly and accurately set a desired normal force, and deviations in the areas of the brake unit 14, such as wear or dimensional differences on the brake unit or a brake rail 9, quickly and directly, that is within the brake unit itself, can be corrected.
  • the susceptibility to failure of the braking device is significantly reduced, since dimensional influences such as rail thickness, Bremsplattenverschleiss or other Abnweilungen directly, be compensated within the brake unit.
  • a replacement is simply possible because the brake unit specific properties of the brake force contained in the normal force control directly, ie within the brake unit itself, detected and corrected.

  • the brake control unit is advantageously as in Fig. 1 represented on the cab, possibly in combination with other control or safety modules arranged. Measuring and monitoring systems, such as in WO03 / 004397 described, are advantageously integrated in such a security module. This makes it possible to provide a braking device 13 which, depending on the load case, can hold or brake with a corresponding braking force F B , which is dependent on the effective normal force F N-eff . Taking into account the current state of the elevator installation 1, the brake control unit 15 determines the optimum, user-friendly and most economical brake application.
  • a brake starting value can be calculated on the basis of the state variables determined by the measuring sensors 20, 21, 22, 23, as a result of which a setpoint value S Bi can be preset.
  • the advantage of this braking device 13 according to the invention can be seen in the fact that a secure on-demand braking or holding of the elevator car 2 is made possible with minimal expenditure of energy.
