Definitions

  • the invention relates to a cable brake for an elevator system for braking a cable coupled to a car, with a fixed in the longitudinal direction of the rope stop and at least one brake shoe, wherein the rope between the stop and the brake shoe is guided and the brake shoe between a press the cable against the stop Brake and a release the rope release position is reciprocable, and with a coupled to the brake shoe linear drive for releasing the rope, wherein the at least one brake shoe against the action of acting in the braking position on it braking force by means of the linear drive can be converted into its release position ,
  • Cable brakes are for example from the EP 0 708 051 A1 known. With their help, for example, coupled with a counterweight of the elevator cable, which is held on the along a roadway up and down movable car, can be reliably decelerated by the at least one movably arranged brake shoe occupies its braking position and thereby pressed the rope against the stop becomes.
  • a rope brake in which a brake shoe can be transferred by means of a pivot lever in its braking position.
  • two compression springs and a hydraulic piston-cylinder unit are articulated to the free end of the pivot lever.
  • the springs exert on the pivot lever permanently from a spring force, which tends to pivot the pivot lever so that the brake shoe assumes its braking position.
  • Contrary to the action of the compression springs of the pivot lever can be held by means of the piston-cylinder unit in a position in which the brake shoe releases the rope. If the brake shoe occupy their braking position, the pivot lever must be pivoted for this purpose and at the same time the piston of the piston-cylinder unit counteracts the force acting on it Pressure medium to be moved.
  • Object of the present invention is to develop a rope brake of the type mentioned in such a way that it has a structurally simpler structure and with their help, the rope can be braked within a shorter time.
  • the brake shoe is permanently loaded in its braking position with a braking force, and against the action of the braking force, the brake shoe can be transferred by means of the linear drive in its release position.
  • the linear drive can be coupled with the brake shoe for this purpose. If the coupling is interrupted, the brake shoe assumes its braking position within a very short time, in which it presses the cable against the stop, so that the rope can be braked within a short time. To release the rope, the brake shoe is acted upon in addition to the braking force acting on it by coupling with the linear drive with a brake force counteracting actuating force of the linear drive so that it can be transferred under the action of the actuating force in its release position.
  • the construction according to the invention also has the advantage that the rope brake can be checked automatically for their function, for example at each car stop. For this purpose, it is only necessary to transfer the brake shoe successively in its two end positions, ie in its braking position and in its release position, and check the end positions of the brake shoe corresponding switching positions of at least one position switch electrically when the car is stationary.
  • the method for testing the rope brake according to the invention will be explained in more detail below.
  • the at least one brake shoe is reciprocable by means of the linear drive between its braking position and its release position.
  • the brake shoe can be transferred by means of the linear drive not only starting from its braking position in its release position, but under the action of the linear drive
  • the brake shoe can also be subjected to a controlled movement, starting from its release position into its braking position.
  • the linear drive can come in a variety of configurations are used, it can be configured for example as an electric, hydraulic or pneumatic drive, in particular as a linear motor or as a piston-cylinder unit. It is advantageous if the linear drive is configured as a threaded spindle or screw drive. This allows a structurally particularly simple and inexpensive to produce structure of the rope brake.
  • the at least one brake shoe is coupled to the linear drive via a pivotably mounted pivoting lever.
  • a pivotably mounted pivoting lever may be provided.
  • the use of a pivot lever allows a power transmission in the way that the brake shoe in its braking position can be acted upon with a large braking force, while the linear drive only a relatively small operating force must be provided to convert the brake shoe despite the effective braking force in their release position.
  • the rope brake comprises a spring element which acts on the at least one brake shoe in its braking position with the braking force.
  • the spring element is designed as a spring with a linear characteristic, so that the spring element acts on the brake shoe with a braking force proportional to the spring travel.
  • the spring element may be configured for example as a plate spring or coil spring.
  • the spring element cooperates with the at least one brake shoe via a pivotably mounted pivoting lever.
  • a one-armed or two-armed pivoting lever which is arranged between the spring element and the brake shoe, has the advantage that even with the provision of a relatively small spring force, a very high braking force can be exerted on the brake shoe.
  • the advantage here is also that the braking force is built on the side of the brake shoe and not on the side of the stop, as can be kept low by a fixed and non-yielding stop the Auslenkweg of the cable to be braked.
  • both the spring element and the linear drive are coupled to the at least one brake shoe via the pivot lever.
  • the pivot lever is used, via which the brake shoe can be acted upon both by the actuating force provided by the linear drive and by the spring force provided by the spring element. It is advantageous in this case if the spring element and the linear drive are arranged in alignment with each other.
  • the spring element is coupled to the pivoting lever via a power transmission element aligned in alignment with the linear drive, for example a rod.
  • the power transmission member may be articulated to the pivot lever.
  • the at least one brake shoe is coupled to the linear drive via an electromagnet and an armature associated therewith. To release the rope brake, it is then only necessary Disconnect the excitation current of the solenoid to disconnect the brake shoe from the linear drive, so that the provided by the linear actuator actuation force is eliminated and the brake shoe passes within a very short time due to the spring force acting on it in its braking position.
  • the electromagnet and the armature between the coupled to the at least one brake shoe pivot lever and the linear drive are arranged.
  • the electromagnet and the armature of the movable brake shoe are arranged directly adjacent.
  • the rope brake can be designed to be very smooth, thereby occurring friction forces between the individual components of the rope brake can be kept low.
  • the electromagnet and / or the armature are held linearly displaceable.
  • the electromagnet and / or the armature by means of the linear drive are linearly movable. This makes it possible to move the armature and / or the electromagnet by means of the linear drive, so that the distance between the electromagnet and the armature by means of the linear drive is adjustable.
  • the electromagnet and / or the armature are movably held on a stationary stand on which the linear motor and the spring element are arranged.
  • the stand can form a fixable in the shaft of the elevator system or in the engine room base of the rope brake, which carries the linear motor and the spring element and has a guide for the movably held electromagnet or the movably held armature.
  • the linear drive itself can be configured with a releasable connection element, for example a coupling.
  • an elastic member is arranged between the linear drive and the electromagnet or the armature. This allows an elastic attachment of the electromagnet or armature to the linear drive by means of a sprung intermediate area. This makes it possible for the linear drive to always travel to the same point even when the cable becomes thinner over time or the braking surfaces of the stop become worn, without the switching paths of the linear drive having to be readjusted.
  • the elastic member of the linear drive can push the electromagnet and the armature together and then the linear drive can be switched off without causing tension.
  • pivot lever is pivotally mounted on the stand.
  • the position of an actuator of the linear drive, a force transmission member of the spring element and / or the position of the pivot lever of at least one sensor can be monitored.
  • This may be a non-contact sensor, for example a reed contact or Hall sensor, but a contact-based sensor may also be used.
  • at least one sensor is designed as an electric, pneumatic or hydraulic position switch.
  • a position switch for example, an electrical Switching contact are used, which can be actuated by means of a switching plunger.
  • the actuator, the power transmission member or the pivot lever Takes the actuator, the power transmission member or the pivot lever a position corresponding to an end position of the brake shoe, the switching rod of an associated switching contact of the actuator, the power transmission member or the pivot lever can be actuated.
  • the assumed switching position of the switching contact can then be checked electrically at any time to determine in this way the position of the associated actuator, power transmission member or pivot lever.
  • the invention also relates to a method for checking the operability of a rope brake.
  • This is inventively characterized by bringing the movable brake shoe successively in its two end positions when the car is stationary and the end positions of the brake shoe corresponding switch positions at least one position switch checked electrically.
  • Such a function test can for example be carried out automatically by the elevator installation at each car stop.
  • the at least one position switch can interact directly with the brake shoe, but it can also be provided that the position switch cooperates with a mechanically coupled to the brake shoe component of the cable brake, for example with the pivot lever or the power transmission member of the spring element.
  • the at least one brake shoe by means of the linear drive in its two end positions, ie when the car is stationary, the brake shoe is subjected to a controlled movement by means of the linear drive, wherein they successively occupies their two end positions.
  • the respective switching positions of the at least one position switch can be checked electrically.
  • the end positions of the brake shoe corresponding switch positions at least one of the pivot lever associated position switch electrically checked. It can thus be checked, for example, on the occasion of a car stop within a short time, whether the pivot lever can assume its end positions, each corresponding to an end position of the brake shoe. This makes it possible, for example, to easily recognize a mechanical blockage of the pivoting lever.
  • the function of an interrupter unit connected in a power supply line of the electromagnet is tested.
  • the disconnection of the exciter current of the electromagnet can be checked, i. H. It can be checked whether, in the event of a fault in the elevator system, the electromagnet can be reliably switched off to decelerate the cable.
  • the electromagnet after having turned off its excitation current, by means of the linear drive in its the release position of the brake shoe corresponding position moves and checked the switching position of at least one of the pivot lever or the brake shoe associated position switch electrically. In this way, it can be detected on the basis of a car content, whether the position of the brake shoe or the pivot lever changes after the switched off electromagnet is moved by the linear drive. If the rope brake is functioning properly, a shift of the switched-off electromagnet should not occur Change in location of the brake shoe and the pivot lever result. If such a change in location is detected on the basis of the switching position of the associated position switch, there is a fault in the rope brake.
  • the electromagnet after being moved in the off state by the linear drive, then foundedvertex by means of the linear drive back into its brake position of the brake shoe corresponding position, then the electromagnet again charged with the excitation current and then moves it again by means of the linear drive in its release position of the brake shoe corresponding position and the switching position of the pivot lever and / or the brake shoe assigned position switch electrically checked.
