Definitions
- the invention relates to a braking device according to the preamble of the first main claim.
- Brake devices and safety gear for elevators are known in the most varied of forms. Most of the time, such braking devices or safety gear work on the principle of wedging. In the course of the release, at least one braking element or a part thereof is drawn into a gap narrowing in the relevant direction of travel and thus exerts a self-reinforcing braking force. In order to then enable further travel, the braking element must be released from the gap and then brought back into its ready position.
- braking devices and safety devices of the current design are already designed in such a way that after braking or after the safety catch, a fully automatic return of the braking element to its standby position is possible.
- These braking devices and safety gear are mostly designed so that the movement that the braking element pulls into the wedge gap is also used to later return the braking element to its own Prepare readiness position, ie to generate a corresponding relative movement. In the course of the movement of the car in the opposite direction, which is necessary for releasing the braking element from the wedge gap, the braking element can then immediately be returned to its ready position.
- the procedure is such that even if no braking effect has developed after the brake has been released, the braking effect is first generated specifically for the purpose of resetting.
- the car is moved further so that the braking element is still retracted and, in the process, generates or drives every relative movement that prepares the subsequent return of the braking element to its standby position.
- the car is then moved in the opposite direction in order to release the braking element from its retraction again. Only then does the braking element return.
- the method is complex and time-consuming and carries the risk of unnecessary wear and tear on the guide rails, since in fact unnecessary braking is carried out just to prepare for automatic release.
- the invention is based on the object of creating a braking device which - if it has triggered, but has not or only slightly acted as a braking effect - again simply, quickly and without the risk of unnecessary wear on the guide rails can be reset.
- the brake safety device according to the invention for an elevator with a rail-guided car has a base body for fastening, as a rule, to the car or counterweight in a floating manner.
- the base body engages around a rail when properly installed. It holds a braking element on one side of the rail in a position that can be braked. He holds another braking element on the opposite side of the rail in a position that can be braked.
- At least one of the braking elements is held at a distance from the rail in its standby position with the aid of a switchable holding magnet against the force of an automatic actuator.
- the last-mentioned holding takes place in such a way that the brake element is pressed away from the holding magnet against the rail when the holding magnet is switched by the actuator. This creates an air gap between the holding magnet and the braking element or such an air gap becomes larger.
- the braking device is designed in such a way that the braking element is drawn in between the base body and the rail by itself if the car is in motion more than insignificantly at the point in time at which the braking element comes into contact with the rail.
- the holding magnet is equipped with an air gap reducing means, by means of which the air gap between the holding magnet and the braking element which has not yet or only slightly drawn in between the rail and the base body can be reduced or eliminated in such a way that the holding magnet again holds the braking element magnetically trapped on it, as soon as it has been switched back to "Hold".
- the brake can also be reset fully automatically without any problems if it has responded, but then no significant braking effect has developed because the braking element or its intended component in the form of a brake wedge or a brake roller does not was drawn into the gap between its base body and the guide rail.
- the air gap between the holding magnet and the braking element which prevents the braking element or its corresponding component from being simply tightened again in this situation, is reduced or even eliminated by the air gap reducing means to such an extent that the holding magnet can again magnetically attract the braking element with sufficient strength - in order to do so or afterwards to return to its ready position.
- a braking device working with a holding magnet now for the first time enables the braking device (including the holding magnet) to be switched to a completely currentless mode as soon as the elevator system goes into standby mode, for example during the few hours of night that are frequented.
- the fact that the braking element or a corresponding component of the braking element is brought into contact with the guide rail is no longer disadvantageous. This is because, according to the invention, a fully automatic retrieval is also possible from this position without first having to trigger the brake, which is costly and subject to wear.
- the air gap reducing means is preferably implemented by a guide, along which the holding magnet can be moved in and against the direction of the braking member resting on the rail (in other words, mostly perpendicular to the direction of travel of the car) and a drive causing such a movement.
- the actuator can also be returned to the standby state very easily in this way. Is the actuator e.g. a compression spring, then this can be tensioned again by reducing the air gap or by moving the holding magnet, which in turn holds the braking element, back into its standby position and thus prepared for its next use.
- the drive comprises a motor-driven screw spindle.
- a motor-driven screw spindle As a rule, there is also a rotary spindle motor that turns part of the screw spindle so that the screw spindle lengthens or shortens, depending on the direction of rotation of the motor. In this way, a large transmission ratio can be achieved very easily.
- a very small motor is then sufficient to apply the comparatively large force that z. B. is necessary to re-tension the actuator.
- the spindle motor can also be kept very small because of this, because it only has to be designed from a thermal point of view to a limited extent due to the comparatively short switch-on time per application. In other words, it can be operated in a load range (overvoltage, overcurrent) that would have to be avoided in the event of prolonged operation, as the spindle motor would then overheat.
- the screw spindle is designed to be self-locking, in such a way that it does not begin to rotate in the direction of its longitudinal axis under the influence of mere forces. This contributes significantly to energy savings. Because this means that the spindle motor can remain de-energized for most of the time and only needs to be energized briefly when it is to actively rotate.
- the drive and actuator are designed and designed in such a way that the drive also tensions the actuator again when it eliminates the air gap of the holding magnet, for example pulling the holding magnet together with the braking element away from the rail.
- an elevator car moving along guide rails, preferably in the vertical direction along an elevator shaft, and with a counterweight which are connected to one another via a suspension element. It can preferably, but not exclusively, be a traction sheave elevator.
- the elevator is characterized in that its car carries a braking device according to one of the claims mentioned.
- a further, independent aspect of the invention is to provide a method for automatically deactivating a braking device of an elevator that has collapsed while stationary or during minimal travel, the braking element of which is held in its standby position at a distance from the rail in regular operation by a holding magnet against the action of an actuator and whose braking element has not yet drawn in between the rail and the base body.
- the actuator is preferably already tensioned.
- Another method that is also claimed is a method for energy-saving stand-by operation of an elevator with a braking device electromagnetically held in its standby position.
- the procedure consists of the following steps:
- the holding magnet is re-energized.
- the elimination of the air gap is carried out in such a way that the actuator is brought back to its ready state, preferably by being tensioned with the application of force.
- one of the agents disclosed by this application is used as the air-split reducing agent.

- FIG. 13 shows the mode of operation of a conceivable alternative solution for the air gap reducing means claimed.
- FIGS. 1 and 4 The best overview of an exemplary embodiment according to the invention is given by considering FIGS. 1 and 4 together.
- the braking device 1 can be seen very clearly in FIG.
- the base body 2 comprises a base body 2.
- the base body 2 is preferably floatingly attached to the car or car frame of the elevator - in such a way that the base body can move relative to the car and to the guide rail 3 in order to move in relation to the To be able to center the guide rail without having to take the car with you. If necessary, it can also be attached to the counterweight, if this is exceptionally secured with its own braking device.
- the elevator car is typically guided on two parallel rails, so that two of the braking devices according to the invention are provided, in each case at least one per rail.
- this base body 2 has a central slot S. In the properly installed state, the slot S overlaps a rail 3 on its two opposite sides.
- the rail 3 can theoretically be an independent brake rail. As a rule, however, the rail 3 will be a guide rail that is already present and that guides the car or the counterweight along the shaft. In the following, the term guide rail is used across the board.
- the base body holds a braking element in position on one side of the guide rail 3.
- this brake element comprises a movable brake lining 4.
- This brake lining 4 is held by means of bolts 5.
- the bolts 5 can slide back and forth in corresponding guides F of the base body 2.
- one or more spring elements 6 are supported between the brake lining 4 and the corresponding part of the base body 2, preferably in the form of disk spring packages.
- the exact position of the brake lining 4 with respect to the guide rail 2 can preferably be determined with the aid of adjusting nuts 7.
- the bolts 5 and the spring elements 6 here form further components of this braking element.
- the base body 2 holds a further braking element in position on the other side of the guide rail 3.
- This braking member comprises a braking roller 8, which will be discussed in more detail shortly.
- Another component of this braking member is the gate 9.
- the gate 9 is attached to the base body 2 so as to be pivotable about the axis 10.
- the gate 9 carries a pendulum rod 11, which in turn carries the brake roller 8.
- the pendulum rod 11 is slidably and pivotably guided by it through a suitable bracket 13.
- the tab 13 can be seen particularly well in FIG.
- the braking roller 8 is connected to the link 9 via this pendulum rod 11.
- the pendulum rod 11 carries a return spring 12, as will be described in more detail in a moment.
- the pendulum rod 11 can be displaced in the direction of the arrow PI under compression of the return spring 12 together with the braking roller 8 carried by it.
- An oscillating, oscillating movement back and forth in both directions of the arrow P2 is possible at the same time.
- the brake roller 8 is therefore controlled by the link 9, but is in one with it specific area movable.
- a holding magnet 14 belongs to the braking device 1.
- An actuator 15 also belongs to it.
- the actuator 15 is designed here as a compression spring or a helical compression spring.
- the actuator 15 has the tendency to pivot the link 9 about its axis 10 towards the guide rail 3.
- the holding magnet 14 prevents such pivoting.
- it attracts a plate section 28, which here preferably runs perpendicular to the plane of the drawing and is part of the link 9. As a result, he holds the backdrop 9 in its position shown in FIG.
- a holding and guide rail 16 is fastened in the base body 2.
- This holding and guide rail 16 is preferably L-shaped. In any case, it carries a linear drive 17.
- the linear drive 17 is designed as a spindle drive with a rotary spindle motor 29 and a screw spindle 18, which is particularly preferred.
- a real linear motor would also be conceivable, although not preferred, since a spindle drive has an optimal transmission ratio and is therefore very small and inexpensive.
- the holding magnet 14, in turn, preferably carries at least one runner 19.
- the runner 19 is attached to the holding and guide rail 16 in a slidable manner via at least one guide screw 20 - in the present, preferred case, the or each guide screw runs in an elongated hole in the holding and guide rail .
- link 9 optionally forms an additional link guide 21. If available the link guide 21 interacts with the brake roller 8 as soon as it is drawn in. The purpose and the more precise nature of this interaction will be described in more detail in the following explanations.
- FIGS. 8 to 12 are schematic representations. That explains the apparent differences to Figures 1 to 7. But that doesn't affect the matter. It is true that the braking device according to the invention according to FIGS. 1 to 7 can be designed accordingly, even if this is not shown in detail in the drawing, at least as far as FIG. 4 does not show.
- the brake roller 8 has a main portion 22 and an axis of rotation LR.
- the main section 22 generally has the largest outside diameter. It is preferably knurled on its outer surface or treated in another way to increase traction.
- a shoulder 23 adjoins this in each case coaxially.
- the shoulder 23 is typically in each case smooth-surfaced, usually ground or provided with a defined roughness.
- a guide pin 24 joins coaxially, which usually has a further reduced diameter compared to the shoulder 24.
- FIG. 9 shows the principle of the braking device according to the invention as long as it is in its standby position, that is, it is not activated in regular operation.
- the base body 2 which is only indicated here, is clearly visible.
- the base body overlaps the guide rail 3 on two opposite sides.
- the brake lining 4 can also be clearly seen. It is held in position by the spring elements 6.
- the backdrop 9 can also be clearly seen. It is held on the base body 2 such that it can pivot about the axis 10.
- the gate 9 is held here by the holding magnet 14 by being magnetically attracted by it.
- the holding magnet 14 overcomes the force of the actuator 15, which has the tendency to pivot the link 9 counterclockwise towards the guide rail 3.
- the link guide 21 can also be clearly seen, which here, in this basic exemplary embodiment, is incorporated into the link 9 as a curved, optionally closed slot.
- the non-activated standby position shown in FIG. 9 is characterized in that the brake lining 4 is at a distance from the guide rail 3.
- the standby position shown in FIG. 9 is further characterized in that the braking roller 8 is held at a distance from the guide rail 3 by the link 9. This is preferably done by a pendulum rod 11 (not shown in FIGS. 9 to 12) and its return spring 12. Both may, for example, be designed as shown in FIGS. 1 to 7.
- FIGS. 9 to 12 the backdrop 9 has been shown partially transparent so that the following can be better explained, which can also be seen relatively well with reference to FIG. 4:
- a running surface 25 is incorporated into the base body 2, cf. necessarily also Fig. 4.
- This has a groove-like recess 26 in its center, cf. also Fig. 4.
- FIG. 10 This shows the principle of the braking device according to the invention after it has been triggered.
- the brake roller 8 is clamped between the points PH and PS.
- the point PH is the contact area between the jacket of the main section 22 of the brake roller 8 and the guide rail 3.
- the point PS is the contact area between the shoulder 23 of the Brake roller 8 and the running surface 25.
- the mostly knurled and possibly also hardened jacket of the main section 22 of the brake roller protrudes into the groove-like recess 26 without touching its groove base. This means that the aggressive, knurled surface of the jacket of the main section 22 has clearance relative to the base body 2. This saves the main body 2 wear and tear due to the aggressive knurling.
- the base body 2 is thereby moved in the direction along the arrows PB relative to the guide rail 3, preferably due to its floating mounting on the car or counterweight .
- the brake lining 4 is pressed against the surface of the guide rail 3. It develops correspondingly high frictional forces.
- the brake roller 8 is drawn even further into the gap between the base body 2 and the guide rail 3 if the car or the counterweight still has a not insignificant speed at this point in time.
- the braking forces are preferably so great that the braking device is caught. It is then a brake safety device.
- the running surface 25 has a reinforced bevel / inclination in the region of its end. This is designed in such a way that it ultimately forms a stop which limits the maximum draw-in depth and on which the shoulders 23 can roll flat without seizing.
- the traction is generally set such that the outer surface of the main section 22 of the brake roller 8 rolls on the guide rail 3, while the shoulders 23 slide on the running surface 25.
- an insert 27 can be provided in the area of the stop for controlling eating damage, which either is easily exchangeable (in the case of seizure damage) or avoids seizure damage from the outset because it consists of a bearing metal or material.
- the braking device 1 is preferably designed to act bidirectionally, as shown here. Then, analogously, the same thing happens when the braking device 1 is triggered while driving upwards. The only difference is then that the brake roller 8 is drawn into the wedge gap between the base body 2 and the guide rail 3 by a downward movement.
- the link 9 is pushed back from the guide rail 3 in the direction of the holding magnet 14 in the course of the retraction of the brake roller 8 between the base body 2 and the guide rail 3 by at least one guide pin 24 of the brake roller 8, in the direction of the holding magnet 14 the air gap is reduced or eliminated when braking or catching, which has opened up between it and the gate 9 by the falling off of the gate 9 from the holding magnet.
- the aforementioned automatic reduction or elimination of the air gap offers the possibility of energizing the holding magnets 14 again.
- the car or the counterweight can be moved again in the opposite direction of travel.
- the brake roller 8 is moved out of the wedge gap between the base body 2 and the guide rail 3.
- the yes is under the tension of its return spring 12, withdrawn again into its ready position, as FIG. 9 shows.
- the braking device 1 can therefore be released again fully automatically after a catch, without having to be reset manually.
- FIG. 1 shows the exemplary embodiment according to the invention in regular operation at a point in time at which the braking device 1 is inactive because it should not be braked.
- the braking device 1 is therefore in its standby position in FIG.
- FIG. 2 shows what happens then.
- the gate 9 in the area of the holding magnet 14 is cut away. This makes the holding magnet behind it easier to see.
- the helical spring which here represents the actuator 15, has pressed the plate section 28 of the link 9 in the direction of the guide rail 3.
- the brake roller 8 rests against the guide rail 3.
- the car may already be stationary or at least no longer move significantly. This is the case, for example, when the car is already at a stop and the brake roller 8 has only been placed prophylactically against the guide rail 3.
- Such a prophylactic system can e.g. B. have the sense of ensuring that the brake roller 8 is retracted and begins to brake, if an undesirable creeping away of the car from its landing position takes place. If the feared sneaking away does not occur, however, the braking roller 8 is not in the gap between the base body 2 and the guide rail 3 retracted. Instead, it then remains in the position shown in FIG.
- the braking device 1 must be deactivated again.
- the brake roller 8 is to be returned to its standby position.
- this does not succeed simply by switching the holding magnet 14 again. This is because the air gap LU between the plate section 28, which here forms the magnet armature, and the end face of the holding magnet 14 is too large. It is not possible for the holding magnet 14 to attract the plate section 28 again across the large air gap LU against the resistance of the helical spring or the actuator 15 formed by it.
- the linear drive 17 is actuated so that it moves the holding magnet 14 in the direction of the guide rail 3.
- the actuation takes place until the air gap LU between the holding magnet 14 and armature, which is preferably formed by the link 9 or its plate section 28, is so small that the holding magnet 14 can magnetically attract and hold the plate section 28 again reliably.
- the linear drive 17 is preferably designed as a spindle drive
- the screw spindle 18 is screwed out of the motor hollow shaft 30.
- the holding magnet 14 Since the other end of the Holding magnet 14 or at least one runner 19 thereof, the holding magnet 14 is shifted purely translationally as a precaution in the direction of the guide rail 3.
- the at least one runner 19 slides along the holding and guide rail 16 - due to its movable fixation by the guide screw 20. The latter is firmly connected to the base body 2 or is even an integral part of the base body 2.
- the linear drive 17 is actuated in the opposite direction. He now pulls the holding magnet 14 together with the held plate section 18, which is magnetically attracted by him, away from the guide rail 3. As a result, the linear drive 17 causes the link 9 to pivot clockwise back into its standby position. In the course of this, the link 9 takes the brake roller 8 back into its standby position. In the specific case, the link 9 exerts the corresponding return force on the brake roller 8 via its tab 13 and the return spring 12 and the pendulum rod 11.
- the linear drive is positioned so that it generates a translational movement that goes back and forth essentially perpendicular to the guide rail 3, but a movement in the direction of the Guide rail conceivable.
- the housing of the holding magnet 14 has a shoulder with a reduced diameter. This reduced diameter forms a seat or an internal guide for the helical spring, which here forms the actuator 15.
- the plate section 18 has a hole. A rod STA of the holding magnet engages through this hole
- the said hole is designed so generously that the rod STA of the holding magnet 14 can pivot back and forth unhindered in this hole. In this way, the actuator
- the holding and guide rail 16 is a component which is initially separate from the base body 2 and which is screwed or riveted to it. In this way, it is possible to retrofit already existing braking devices of this type so that they can be deactivated again without having to be manually active or having to start braking or catching beforehand.
- the air gap reducing means is ideally but not necessarily a linear drive that moves the holding magnet 14 back and forth.
- Each of the pole pieces forms a flat, wedge-shaped tongue with a slight slope.
- the wedge-shaped tongues of the pole pieces Kl and K2 are oriented in opposite directions and together form a flat top and bottom.
- the pole pieces Kl and K2 are made of magnetically conductive material (e.g. steel). They are pushed from both sides into the air gap LU, which is initially too large for the plate section 28 to be tightened again by the holding magnet 14. They close the air gap completely or substantially, as shown in FIG. 13.
- the holding magnet 14 can attract the plate section 28 again with great force via the pole pieces, although the holding magnet 14 is actually too far away from the plate section 28 for this purpose.
- the pole pieces are then laterally pulled out of the air gap LU by the tensile forces ZI and Z2 in the opposite direction, preferably at the same speed, whereby they slide off on the plate section 28 or on the holding magnet 14.
- the plate section 28 and thus the magnet armature is continuously brought closer and closer to the holding magnet 14 without a disruptive air gap being created again.
- the plate section 28 “jumps” onto the holding magnet 14.
- the brake claimed in this way can additionally have one or more features disclosed in the above description and / or in the claims and / or in the associated figures.
