Definitions
- the invention relates to a rope brake for an elevator installation, an elevator cage with rope brake and an elevator installation with a rope brake.
- Brakes for braking an elevator car are known in a variety of ways. From the prior art rope brakes are known for example from WO 03/002446 AI or EP 0 651 724 Bl, which are fixedly mounted in the elevator shaft and cooperate with a rope which is moved with the elevator car.
- Brakes may also be connected to the elevator car or to the counterweight of an elevator car and cooperate with a rail fixed in the elevator shaft, as shown for example in EP15186504.5 (not yet published), or as a rope brake with a brake cable immovably mounted in the elevator shaft, such as for example in DE 11 2011 104 744 T5 or US 2,550,839.
- Cable brakes usually have a fixed element and a relative thereto movable element.
- a fixed element usually have a fixed block with a conical opening, within which two conical tapered wedges are movable, which in the case of braking into the conical opening hineinrut- see and approach, so that they pinch an ongoing between them rope.
- EP0651724 shows a cable brake in which a movable brake shoe is guided by a sprung cam device.
- the spring means is held in the open position by a releasable locking means, for example a latch connected to an electrically operable solenoid.
- a releasable locking means for example a latch connected to an electrically operable solenoid.
- Feder compressed, which is caused by a piston-cylinder unit.
- part of the braking force must be used for the movement of the piston.
- EP 1646575 discloses a cable brake in which a brake shoe coupled to a pivotably mounted lever can be moved back and forth between its braking position and its release position by means of a linear drive.
- the linear drive can be coupled to an electromagnet.
- CN202214111U discloses a rope brake according to the preamble of claim 1.
- a cable brake for an elevator installation which comprises at least one pair of brake shoes, which have mutually facing braking surfaces, wherein the brake cable between the braking surfaces is feasible.
- the braking surfaces specify a rope feedthrough direction. Since the brake cable usually runs vertically, the rope feed direction in the mounted state usually corresponds to the vertical.
- the brake cable is designed as a so-called upright rope, which is stretched or fastened in the elevator shaft along the direction of travel of the elevator car.
- a braking force caused by the cable brake is introduced into the brake cable and transmitted via the brake cable into a building structure.
- the brake cable is preferably fastened in the upper region of the elevator shaft.
- the brake cable is preferably fastened in the lower region of the elevator shaft, for example by means of a fastening clamp, by means of a tension spring or a tension weight.
- At least one first brake shoe is movable for movement of the braking surface between a braking position in which the cable can be pressed against the braking surface of the other brake shoe, and a release position in which the cable can be released between the brake shoes.
- a brake shoe is fixedly mounted and a brake shoe movable relative thereto.
- the cable brake preferably comprises a releasable holding device, which acts on the first brake shoe in the release position with a holding force.
- the rope brake has a rear part device, by means of which the first brake shoe can be transferred from the braking position into the release position.
- a braking position is to be understood as meaning a position of the brake in which the first brake shoe begins to clamp the cable between the brake shoes.
- the return device is thus advantageously not designed to return the first brake shoe from the fully cocked braking position.
- At least two rotatably mounted pivot arms are connected to the first brake shoe.
- the pivot arms are arranged in a parallelogram, one side of which is aligned parallel to the rope feed direction.
- the pivot arms are on the one hand rotatably hinged to a cable brake housing and on the other hand rotatably connected to the first brake shoe.
- the parallelogram is formed by the pivot arms and the connecting lines of the articulation points, on the one hand on the housing, on the other hand on the brake shoe.
- the parallelogram lies in a plane that is parallel to the rope feed direction.
- the braking surface of the first brake shoe thus always remains parallel to the rope feed direction and the braking surface thus remains in the transition from the release position to the braking position parallel to the other braking surface.
- the approach of the braking surfaces is thus uniform over the entire surface. A selective jamming or crushing of the rope is thus prevented.
- the holding device comprises a switchable electromagnet, which holds the first brake shoe in the release position, in particular when current is applied.
- the lock can be released very quickly in case of braking, without, for example, a mechanical displacement of a bolt is necessary. It is also excluded that there is a malfunction of a mechanical component, such as a break or jamming.
- the holding device and the rear part device are separate devices. Therefore, the holding device can not only be operated quickly, it can also be arranged completely independently of the rear part.
- the holding device can be arranged substantially in the same plane as the pivot arms forming the parallelogram.
- the electromagnet can cooperate, for example, with an armature which is arranged on a pivot arm. This not only a compact, but also flat arrangement is possible.
- the brake shoes each have a braking surface and are preferably designed to brake exactly a rope. For this they preferably have an extension which is longer in the direction of the cable feedthrough than transversely thereto.
- the brake shoes in particular have braking surfaces with a shape that are adapted to the shape of the rope.
- the braking surfaces have a part-cylindrical shape and are thus suitable for a rope with a round diameter.
- the pivot arms on a spring device which acts on the first brake shoe in the braking position with a spring force.
- Each swivel arm is equipped with at least one respective brake spring, for example a disk spring or a packet of disk springs.
- the brake spring ensures that the brake shoes are still sprung against each other even if it comes to a contact with the rope and the brake shoes are pulled by the friction with the rope in the braking position. Squeezing the rope is thus avoided.
- the brake spring is biased for example between two discs.
- the brake springs are designed as brake pressure springs and the brake pressure is adjustable.
- the pivot arms are in the release position at an angle to a perpendicular to the rope feed direction, in particular in the mounted state by an angle relative to the horizontal, deflected.
- the pivot arms are deflected in the release position, for example, in the assembled state down when the rope brake is mounted on an elevator car and the falling of the car should be prevented.
- the pivot arms may also be deflected upwardly to prevent upward acceleration.
- the first brake shoe can be transferred to the release position while the current is applied to the rear part device. This can be done for example by means of a spindle motor or a pressure-actuated plunger.
- the rear-part device preferably comprises a switchable lifting magnet.
- the solenoid reacts immediately to a change in the current.
- the rear part device is arranged in particular so that it acts on a pivot arm.
- a solenoid can be equipped with a lifting rod that presses on a counterpart on one of the pivot arms.
- the rear part device can act on a different pivot arm than the holding device or it can act on the same pivot arm, but from an opposite side.
- Rear part device, holding device and pivot arms can thus be arranged substantially in one plane, which further favors the flat design of the rope brake.
- the cable brake on a stop which is arranged so that in the braking position in which the cable is clamped between the brake shoes, at least one pivot arm and / or the first brake shoe rests against the stop.
- the stop thus defines a certain limit position of the pivot arms and / or the first brake shoe, in which the pivot arms and the first brake shoe are also held under the influence of a frictional force, which is caused by a relative to the brake shoes moved rope.
- the pivot arms can therefore not slip out of the braking position.
- the articulation points of the pivot arms in the braking position form a rectangle.
- the pivoting arms are directed in the direction of the vertical to the rope feedthrough direction.
- Brake shoes have in this position of the articulation points on the cable brake housing the maximum distance and the parallelogram has its maximum extent.
- the brake springs can deploy their braking force in the direction of the opposite brake shoe and thus optimally in the direction of the rope.
- the stop is arranged so that the parallelogram occupies approximately a rectangular position in case of braking.
- the holding device and / or the restoring device of the cable brake are inactive in the brake case, in particular de-energized. In the event of a power failure, the rope brake thus automatically switches over to the braking position.
- the holding device and the return device are coupled to each other such that the return device is only activated, so can transfer the first brake shoe in a release position when the holding device is active, the holding device is therefore ready, the first brake shoe in one Hold release position.
- the cable brake comprises an electrical circuit which ensures that a switchable lifting magnet of the rear-part device can only be acted upon by current when the switchable electromagnet of the holding device is supplied with current.
- the lifting magnet Upon release of the electromagnet, the lifting magnet is also necessarily de-energized. This ensures that the rear part device is switched powerless when, for example, during a reset an error is detected and thereby the switchable solenoid is released.
- the brake shoe can then freely return to the braking position of the rear part device.
- the cable brake comprises a safety device, in particular a speed limiter, or can be coupled to a safety device, in particular a speed limiter.
- the securing device is set up in such a way that it ensures release of the holding device as soon as a predeterminable or predefined speed is exceeded.
- the electromagnet of the holding device can be controlled by the securing device.
- the rope brake comprises a housing in which the brake shoes, the pivot arms, the Gareinrich- device and the rear part device are arranged.
- the housing can be connected to an elevator car so that the cable brake preferably cooperates with a brake cable fixedly mounted in an elevator shaft.
- a particularly preferred flat arrangement of the rope brake is made possible when the holding device and the rear part device, and optionally the stop, are arranged on a common housing plate, on which the pivot arms are articulated. On the same housing plate, a fixed brake shoe can be mounted.
- a cable brake is provided with at least one infeed spring, which causes a force in the direction of the braking position on the first brake shoe.
- the feed spring is preferably rotatably mounted about an axis which is arranged parallel to the axes of rotation of the pivot arms.
- the feed spring is on the one hand rotatably hinged to a cable brake housing and on the other hand rotatably connected to the first brake shoe.
- the spring can thus be arranged in the substantially same plane as the parallelogram forming pivot arms and does not affect the flat structure of the rope brake.
- the feed spring ensures that the first brake shoe moves in the direction of the braking position after releasing the holding device.
- the spring force of the spring has a force component in rope feed.
- a plurality, preferably four, parallel to each other arranged delivery springs are provided.
- the force in the direction of the braking position is thus distributed to the Zustellfedern.
- the spring forces are preferably designed so that in case of failure of a spring, for example, in a break, the remaining springs still apply a sufficiently large force for safe movement of the brake shoe.
- each of the springs must apply at least 150% of the necessary force. Overall, this results in a spring force of at least 300%.
- the required 150% of the necessary force is provided in the event of failure of a spring from the remaining three springs.
- the maximum available actuation force in a configuration with four springs thus only corresponds to at least 200% of the necessary force.
- the springs can be tension springs. Tension springs are cheap and they need no further guidance.
- the feed spring is arranged so that it is deflected in the release position relative to a perpendicular to the rope feedthrough direction by a feed angle and in the braking position by an angle which is smaller than the feed angle.
- the spring force component is smaller in the direction of cable feed in the braking position than in the release position. The Zustellfedern can therefore be relatively easily transferred from the braking position back to the release position, with the necessary force increases with increasing angle.
- the cable brake comprises guide rollers for aligning the cable with respect to the brake shoes.
- the guide rollers are preferably arranged in pairs along the rope feedthrough direction and fastened to the cable brake housing.
- the guide rollers are particularly necessary when the cable brake is attached to an elevator car and cooperates with a fixed brake cable.
- the elevator car is usually performed in the elevator shaft, but the brake cable can still have a certain game compared to the elevator car.
- the hemming rollers ensure that the brake cable is always centered between the brake shoes.
- an elevator car with at least one rope brake as described above.
- the rope brake is especially firmly connected to the elevator car.
- the rope brake can be integrated in an outer wall of the elevator car.
- the cable brake preferably comprises a housing which is connected to a supporting structure of the elevator car, for example to the floor of the elevator car.
- the rope brake is then easily accessible, for example for maintenance purposes.
- an elevator car is equipped with two cable brakes which cooperate with standing on both sides of the elevator car standing brake cables.
- the brake cables and thus the rope brakes can be arranged, for example, on opposite sides of the elevator car on a middle or symmetry line of the elevator car, or they can be arranged along a diagonal line rotated to the center line or line of symmetry of the elevator car.
- the arrangement is such that a guiding force effect on the guide rails is minimal.
- the braking force is transmitted evenly in the event of a brake on the elevator car.
- Elevator cabs can be guided along guide cables through the elevator shaft.
- the elevator car is equipped with a rail guide.
- the rail guide preferably comprises two guide elements. These may be arranged laterally on the elevator car or on a wall of the elevator car, which corresponds to a so-called "piggyback arrangement".
- an elevator system with a cable brake as described above and / or elevator car as described above and at least one brake cable, which in particular can be fixedly mounted in an elevator shaft.
- a cable brake as described above and / or elevator car as described above and at least one brake cable, which in particular can be fixedly mounted in an elevator shaft.
- two brake cables are provided in an elevator shaft for an elevator car.
- the elevator installation comprises hollow rails for guiding the elevator cage.
- the hollow rails may be arranged on opposite shaft walls or for a "piggyback arrangement" side by side on a wall. Since braking is effected via a brake cable in the case of braking, the system still requires brake cables in addition to the rails, but unreinforced hollow rails can be used to guide the elevator car. Unreinforced hollow rails are designed to guide the elevator car, but are not sufficiently pressure-resistant for braking. They are usually much cheaper and easier to install than reinforced rails.
- the object is also achieved by a method for braking an elevator car, in particular as described above, with a cable brake, in particular as described above, with the following steps.
- a holding device is released and at least one first brake shoe is transferred from a release position to a braking position, wherein at least two rotatably mounted, connected to the brake shoe pivot arms change their position.
- the pivot arms are arranged in a parallelogram, one side of which is parallel to the cable feedthrough direction.
- the release of the holding device takes place in that the power supply is interrupted to an electromagnet.
- the electro-adhesive magnet acts on a counterpart, which is attached to one of the pivot arms. If no more holding force acts on the pivoting arms, the pivoting arms typically change their position due to the spring force of the adjusting springs, which pull the first brake shoe in the direction of the braking position.
- a limit position of the brake shoe is reached when the brake shoe or at least one of the pivot arms strikes against a stop.
- Brake springs for example, integrated in the swivel arms, determine the contact pressure of the
- the brake shoes can be brought back into a release position.
- the solenoid pushes, for example, a brake shoe or a swing arm back into a cocked position in which the brake shoe or the swing arm is held by the electromagnet.
- a rope brake cooperates with a preferably standing rope or brake cable.
- this may also have the same effect as a rail brake, which then with a corresponding brake rail, preferably a correspondingly shaped guide rail cooperates.
- a rail is to be understood instead of the cable.

- Fig. 5a is a schematic representation of a second example of an elevator installation in one
- Fig. 5b is a schematic representation of the second example of an elevator installation in a side view.
- Figure 1 shows a rope brake 1 in the release position in a side view.
- Figures 2 and 3 show the same cable brake 1 in the braking position.
- the rope brake 1 comprises two brake shoes 2, 3 which have mutually facing braking surfaces 4, 5.
- the brake cable 24 not explicitly shown in FIGS. 1-3 is along one
- a first brake shoe 2 is connected to two rotatably mounted pivot arms 10 a, 1 Ob, which are arranged as a parallelogram, one side, so for example, the line connecting the Ansch- points on the brake shoe 2, is aligned parallel to the rope feed 6.
- the rope brake 1 has a releasable holding device 8, which acts on the first brake shoe 2 in the release position with a holding force.
- the holding device 8 comprises a switchable electromagnet 14, which holds the first brake shoe 2 in the release position when current is applied.
- the electromagnet 14 cooperates with an armature 28 which is mounted on one of the pivot arms 10a and holds the pivot arms 10a, 10b at a deflection angle 33 with respect to a perpendicular 13 to Seillufood substances 6. Once the solenoid 14 is energized, no more holding power and the Swing arms 10a, 10b can change their position. In the braking position, the articulation points of the swivel arms 10a, 1 ob form approximately a rectangle.
- the change of position is effected by, for example, four feed springs 19, which are arranged parallel to one another. They provide a force in the direction of the braking position.
- the delivery springs 19 are preferably mounted rotatably about an axis 29 which is arranged parallel to axes of rotation 30 (FIG. 3) of the pivot arms 10a, 10b.
- the Zustellfedern 19 are deflected in the release position relative to the vertical 13 to the rope feedthrough direction 6 (in the mounted state relative to the horizontal) by a feed angle 12a and in the braking position by an angle 12b, which is smaller than the feed angle 12a.
- the closing force component of the delivery springs 19 is therefore smaller in the braking position, in which the frictional force of the cable acts anyway, than in the release position.
- the return device 9 comprises, for example, a switchable lifting magnet 15, which is arranged in particular so that it acts on a pivoting arm 10a.
- the solenoid 14 and the solenoid 15 are switched so that they are de-energized in case of braking.
- the electromagnet 14 and the lifting magnet 15 are preferably coupled, so that the lifting magnet 15 can only be energized when the electromagnet 14 is energized.
- the pivot arms 10a, 10b have a spring device 7, which acts on the first brake shoe 2 in the braking position with a spring force.
- each pivot arm 10a, 10b each with a brake spring 11, for example, a prestressable compression spring, in particular a plate spring or a packet of disc springs equipped.
- the rope brake 1 has a stop 16, which is arranged so that at least the first brake shoe 2 rests in the braking position on the stop 16.
- the rope brake 1 may comprise a position sensor 34, via which it can be determined whether the rope brake 1 is in the braking position. If an application of the rope brake is detected via the position sensor 34, a normal travel of the elevator can be prevented for this case.
- the position sensor 34 may be designed as a switch, which is actuated when a pivot arm 10 b abuts in the braking position to the position sensor 34.
- the cable brake 1 preferably comprises a housing plate 18, which forms a housing 17 together with a cover, not shown in the figure (see FIGS. 4a, 4b, 5 a, 5b).
- the pivot arms 10a, 10b hinged and a brake shoe 3, the holding device 8 and the rear part 9 fixedly mounted.
- the guide rollers 23 by means of spring means 35 are elastically coupled to the brake shoe 3, so that when pressing the brake cable to the brake shoe 3, the guide rollers 23 retreat can.
- a holder 31 is also provided for fixing the Zustellfedern 19.
- FIG. 4a shows a schematic representation of a first example of an elevator installation 25 in a top view from above
- FIG. 4b shows a schematic illustration of the same example for an elevator installation 25 in a side view.
- two hollow rails 26 are provided, which are mounted on two opposite walls.
- the hollow rails serve to guide an elevator car 20.
- the brake cables 24 are arranged along a diagonal line 36 rotated to the center or symmetry line of the elevator car 32.
- rope brakes 1 are attached to the elevator car 20.
- the rope brakes 1 each comprise a housing 17 which is fixed to a supporting structure of the elevator car 20, such as the floor 21 or a support frame.
- FIG. 5a shows a schematic illustration of a second example of an elevator installation 25 in plan view from above
- FIG. 5b shows a schematic representation of the same example for an elevator installation 25 in a side view.
- two hollow rails 26 are provided, which are mounted on a wall. The hollow rails 26 serve to guide an elevator car 20 and cooperate with rail guides 22, which are attached to the elevator car 20.
- the brake cables 24 are arranged on opposite sides of the elevator car 20 on the middle or symmetry line 32 of the elevator car 20. Cable brakes 1 are attached to the elevator car 20 correspondingly.
- the rope brakes 1 comprise a housing 17 which is fixed to the floor 21 or a supporting structure of the elevator car 20.
- the rope brake 1 is constructed very flat, so that it finds space in a confined elevator shaft space next to an elevator car 20.
- the rope brake 1 can typically be used for brake cables 24 with diameters between 11 and 19 mm.
- a pair of rope brakes can secure transport loads between 1000 and 2000kg.
- the overall depth is only about four times the rope diameter and is largely determined by the components used, for example, the diameter of the brake springs 11 or the electromagnet 15. Thus, for example, a depth of about 50mm with a height of more than 500mm is conceivable.
