Definitions

  • the invention relates to an elevator safety device with a special release according to the preamble of claim 1.
  • Elevator safety devices have long been in use in various forms. These are braking and safety devices or devices for limiting overspeed or for so-called protective space protection.
  • All of these elevator safety devices typically operate with a trigger.
  • This trigger activates the elevator safety device as soon as it is required.
  • the trigger is typically designed to be held in its ready position against the tension of a main spring.
  • This main spring ensures that the trigger can be activated with the required force as soon as it is activated.
  • the trigger is held in its ready position by overcoming the force of the main spring. This holding is typically done with the help of a purely mechanical solution, more recently also by means of an electromagnetic actuator, which is able to overcome the force exerted by the main spring.
  • a main spring one-piece or composed of several spring elements
  • the actuator which is also electromagnetic, has to apply relatively large forces in order to hold the trigger in its standby position, against the action of the main spring. Because of this, the electromagnetic actuator usually consumes a relatively large amount of energy.
  • an elevator safety device with a trigger is known, wherein the trigger can be activated with the required force as soon as it is activated. Until then, the trigger is held in the standby position by overcoming the force of the main spring, the holding being carried out via a lever system.
  • Other elevator safety devices with a trigger are off WO 2016045932 A1 and WO 2013092239 A1 known.
  • the invention is based on the problem of creating an elevator safety device with a trigger that consumes less energy in regular operation without having to use a weaker main spring, i.e. without having to compromise on the force that the trigger can raise when activated.
  • the elevator safety device has a trigger.
  • the trigger allows the elevator safety device to respond as soon as it receives a corresponding, usually electrical control signal, or if there has been a power failure.
  • the trigger comprises an actuating element which is pretensioned with the aid of at least one one-part or multi-part main spring.
  • the main spring gives the actuator the force it needs to do its job.
  • the elevator safety device has an electromagnetic one Actuator that holds the actuating element by means of the force it generates electromagnetically against the tension of the main spring in its standby position, which it has to assume in the regular, trouble-free elevator operation, while the actuating element is brought into its release position by the main spring as soon as the electromagnetically generated force of the actuator drops, ie completely collapses or at least drops so far that the actuator can no longer remain in its previous position.
  • the electromagnetic actuator does not act directly but only indirectly on the actuating member.
  • a converter is provided as a mediator between the actuator and the actuating element.
  • the converter is designed in such a way that the force that the actuator has to apply electromagnetically in order to keep the actuating element in its standby position is smaller than the force generated by the tension of the main spring.
  • the force that the actuator has to apply is at least 25% and, better still, at least 50% less than the force generated by the tension of the main spring.
  • the elevator safety device is preferably designed in such a way that the elevator safety device additionally has at least one second electromagnetic actuator.
  • the task of the second actuator is to reset the actuating element from its trigger position to its ready position.
  • the second actuator is equipped with a means by means of which it can be coupled again to the actuating element located in the release position, which in its release position is initially completely separated from the second actuator.
  • the second electromagnetic actuator is designed in such a way that it can move the actuating element back into its standby position against the force of the at least one spring.
  • the first and the second actuator can be identical.
  • the actuator is preferably an electric motor which acts on the actuating member via a non-self-locking spindle drive.
  • the first actuator is preferably continuously energized in regular elevator travel, while the second actuator is not energized in regular elevator travel.
  • An embodiment of the elevator safety device is particularly preferred in which the first electromagnetic actuator actuates a locking element.
  • the first actuator and the locking member are designed and cooperate in such a way that the actuating member is held positively locked by the locking member in its standby position as long as the first electromagnetic actuator is energized.
  • the forces of the main spring are diverted in such a way that they do not load the first actuator because it is not in the force flow of the main spring.
  • the locking member is brought by the first actuator or its auxiliary spring, as soon as this is no longer energized or under-energized, in a position in which the positive locking is canceled.
  • An elevator safety device claimed both in connection with claim 1 and separately therefrom is designed as follows: It has a trigger which has an actuating element pretensioned with the aid of at least one main spring and an electromagnetic actuator which electromagnetically actuates the actuating element by means of it generated force against the tension of the main spring holds in its standby position. In contrast, the actuating element is brought into its release position by the main spring as soon as the electromagnetically generated force of the actuator drops.
  • the actuator is a solenoid which, when energized, holds at least one blocking element or a blocking rod against the action of an auxiliary spring in a position that forces positive engagement between at least one radially movable holding element and the actuator.
  • the auxiliary spring does not exert any force on the actuator. It only has the function of moving the blocking element in the de-energized or under-energized state of the solenoid into a position in which the positive engagement between the at least one holding element and the actuating element can be canceled by the force of the main spring.
  • the at least one holding element or the at least one holding ball engages positively in the actuating element through a passage opening of a holding tube and is supported on the blocking rod, the holding tube and the actuating element.
  • the blocking rod does not lie in the force flow, at least in the direction of its longitudinal axis. The force with which the main spring loads the actuating element is transmitted from the actuating element to the at least one holding element or the at least one holding ball and passed on from there to the holding tube. Because the holding element or the holding ball rests against the reveal of the passage opening of the holding tube.
  • the trigger 1 has an actuator 2 on which a main spring 3 acts.
  • the actuating member 2 is designed in the manner of a push rod or a pressure piece which, for example, can push a brake wedge of a brake safety device into a wedge gap - which will be explained in more detail later with reference to a figure.
  • the actuating member 2 has to apply a considerable force in order to be able to press the brake wedge safely into the wedge gap, so that the car is actually caught. This power must also be available in the event of a total power failure. To ensure this, the actuator 2 is when it is of Figure 1 assumes the position shown, under the bias of the main spring 3. The main spring 3 is relatively strong, so that the actuator 2 can be active with a sufficiently large force.
  • the actuating member 2 is movably slidably mounted on the holding tube 13, while the holding tube 13 is in turn designed to be translationally movable, which will be explained in more detail later.
  • the actuating member 2 preferably has an imaginary cross section of an internally hollow T.
  • the "stem" of the T forms a guide section.
  • the main spring 3 overlaps it on the outside, preferably in order to support / guide it. It runs with its inner circumference on the holding tube 13.
  • the imaginary crossbeam of the T forms a functional section with the aid of which the actuating element can be kept in its standby position.
  • the actuator 2 is by a first electromagnetic actuator in its of the Figure 1 shown standby position.
  • this first electromagnetic actuator is a solenoid 11.
  • this solenoid 11 does not act directly on the actuating element 2, but only indirectly via a converter.
  • This converter is formed here by the blocking device or blocking rod 9 coupled directly to the solenoid 11 in conjunction with the at least two retaining balls 10 and the retaining tube 13.
  • the blocking rod is preferably translationally displaceable parallel to the direction of movement of the actuating member 2.
  • the holding tube has through openings for the holding balls 10.
  • This preferred converter therefore works on the principle of the so-called ball locking bolt.
  • instead of the retaining balls 10 differently designed retaining bodies can also be used, for example in the form of a pen, which then z. B.
  • the actuator 2 has a coupling approach that enables the converter 9, 10, 13, to interact positively with the actuator to keep it in its ready position.
  • the coupling attachment preferably has the shape of a recess 15 which is ideally attached to the inner circumference of the actuating member 2, which is hollow on the inside.
  • the retaining balls 10 have inserted themselves into this recess 15.
  • the retaining balls 10 each pass through a passage opening in the retaining tube 13.
  • the retaining balls 10 are prevented by the blocking rod 9 from moving into the retaining tube 13 in a radially inward direction. In this way, the actuating member 2 is locked in a form-fitting manner with the holding tube 13.
  • the actuator 2 remains in its standby position. This state continues as long as the solenoid 11 is energized.
  • the solenoid 11 As soon as the solenoid 11 is no longer energized, for example because there is an arbitrary trigger signal that triggers an interruption of the power supply to the solenoid, or because the voltage supply has collapsed (blackout), the holding force developed by the solenoid collapses.
  • the auxiliary spring 12 which has hitherto been kept tensioned by the holding force of the solenoid, can move the blocking rod 9, in the present exemplary embodiment to the right.
  • the actuating element 2 is thus released and can be brought into its release position by the main spring 3, in which the force imparted to it by the main spring 3 is applied passes on as intended.
  • the actuator 2 now takes the from Figure 2 position shown.
  • a second electromagnetic actuator is used to return the actuating member 2 from its release position to its standby position and to preload the main spring 3 again.
  • This second electromagnetic actuator is implemented by the electric motor 6 in this exemplary embodiment.
  • This motor 6 interacts with the holding tube 13 in such a way that it can move it translationally back and forth.
  • the motor is preferably a rotary motor, since such a motor is usually significantly cheaper than a linear motor with the same output, not least because it can work with a reduction.
  • the motor 6 preferably acts on the holding tube 13 with the aid of a ball screw drive.
  • the ball screw drive is designed to be self-locking, so that the main spring 3 does not cause the ball screw to rotate (if possible not under the influence of general operating vibrations) when the motor 6 is switched off and no longer applies any torque.
  • the motor 6 moves the holding tube 13 in the direction of the actuating member located in the release position - in the exemplary embodiment shown here, to the right.
  • the motor 6 is temporarily stopped.
  • the first actuator is now activated again.
  • the solenoid 11 pulls the blocking rod 9 against the force of the auxiliary spring 12, in the present exemplary embodiment to the left.
  • the retaining balls 10 are pushed by the blocking rod 9 again through the openings in the retaining tube 13 radially outward into the recess 15 of the actuating member 2 and are blocked in this position.
  • the holding tube 13 and the actuating member 2 are now positively connected or locked to one another again.
  • the first actuator now remains activated until the next trigger event, i. H. energized.
  • the motor 6 is energized in a reversing manner in such a way that it pulls the holding tube 13 back into the position (to the left in the case shown in the figure) in which the holding tube holds the actuating element against the force of the main spring 3 in its standby position.
  • the holding tube 13 is made of his of Figure 4 position shown in the position shown by Figure 1 position shown.
  • the comparatively strong motor pretensions the main spring 3 without difficulty and preferably also applies additional force as a so-called useful force, e.g. B. Force with which a brake wedge is pulled out of the wedge gap, or force that moves another component other than the actuator.
  • the actuator 2 has reached its ready position again and is ready for the next use.
  • a ball screw drive consists of a threaded sleeve that acts on a threaded rod via balls. As a rule, the threaded sleeve is driven by a motor, while the threaded rod forms the output, which is also preferred here.
  • a ball screw drive is the means of choice because it minimizes friction losses and realizes a strong gear ratio to slow speed, so that a significantly smaller and higher-speed motor is sufficient.
  • the ball screw saves the holding tube 13 from rotating. This makes it very easy to accommodate the first electromagnetic actuator 4 in the form of the solenoid 11 inside the holding tube 13, which would be more difficult because of the power supply if the holding tube 13 rotates itself.
  • the construction of this exemplary embodiment is characterized by its particularly compact dimensions, which are made possible by the fact that the blocking rod 9 is accommodated in the holding tube 13.
  • the construction is also characterized by its particularly low power consumption during operation.
  • the solenoid 11 which is normally to be energized over a long period of time, can be comparatively weak, because it does not have to apply any force which the force of the much stronger main spring 3 balances. Instead, the solenoid 11 only has to apply that much smaller force which is required to overcome the force of the auxiliary spring 12, against which the blocking rod 9 has to be held in its position ensuring the blocking. That saves a lot of energy.
  • the motor that implements the second actuator here can be powerful and draw a correspondingly large amount of current. In this way and as a result of the thread reduction, with the help of which the motor acts on the actuator 2, the motor 6 can apply large restoring forces - as they are, for. B. are necessary to pull a brake wedge out of the wedge gap between the guide rail and the actual brake body.
  • the high power consumption of the motor or the second actuator is not significant for the energy balance, since it only has to be energized for a short time for the reset process and can then be switched off again permanently until the next "retrieval" after "triggering".
  • the first actuator in this exemplary embodiment in the form of the solenoid 11, is accommodated completely or at least predominantly within the second actuator, which in this exemplary embodiment has the shape of an electric motor 6. This saves a considerable amount of installation space and makes the trigger 1 smaller.
  • the transducer which in this exemplary embodiment is implemented by the blocking rod 9, the retaining balls 10 or the retaining body and by the retaining tube 13, is predominantly (or at least 1/3) housed within the actuating member 2. This also allows a very compact design.
  • the Figure 5 shows the basic functional principle of a further, alternative exemplary embodiment for a trigger 1 to be used according to the invention.
  • the actuating element 2 can be clearly seen here, which is pretensioned by the main spring 3 and, after being triggered, receives the force from the main spring 3 that pushes the actuating element 2 into its release position and conveys the force that the actuating element 2 has to raise in order to fulfill the intended function.
  • the first electromagnetic actuator 4 can also be clearly seen here, which serves to hold the actuating element 2 in its standby position and which is de-energized in order to release the actuating element 2 so that it is in its release position by the main spring 3 can be brought.
  • the first electromagnetic actuator 4 here consists of a solenoid 11 and a rocker 19, which are arranged on a threaded nut 24 or are in operative connection with such a nut.
  • the solenoid acts on the rocker 19.
  • the threaded spindle 20 is driven by an electric motor 6 and thereby moves the threaded nut 24 translationally back and forth as required.
  • the threaded spindle 20, you The electric motor 6 and the threaded nut 24 form the second actuator here.
  • the rocker 19 forms the converter in this exemplary embodiment.
  • the rocker 19 is for this purpose pivoted off-center, in the bearing point 21.
  • the rocker has a short lever arm 22 and a long lever arm 23.
  • the short lever arm 22 cooperates with the actuator 2 to the actuator 2 in its Hold the standby position.
  • the long lever arm 23 of the rocker interacts with the solenoid 11. This means that the long lever arm 23 is acted upon by the solenoid 11 with a torque as long as the solenoid 11 is energized. At the moment in which the solenoid 11 is no longer energized, the long lever arm 23 comes free.
  • the actuating member 2 which is acted upon by the main spring 3 with a force, can push the rocker 19 aside. This enables the actuator 2 to leave its standby position. It is pressed into its release position by the force of the main spring 3. The actuator 2 then passes the solenoid 11.
  • the electric motor 6 is actuated. With the aid of the threaded spindle 20, he moves the threaded nut 24 and thus the solenoid 11 attached to it in such a way that it passes the actuating member 2 again. As a result, the solenoid 11, together with its rocker 19, returns to a position in which the solenoid 11 can be energized. It pulls the rocker back on and thereby brings the rocker 19 back into a position in which the rocker 19 is coupled to the actuating member 2 again. The motor is now energized in such a way that it moves the solenoid 11 together with the rocker 19 held by it and the actuating member 2 against the force of the main spring 3 back into its standby position.
  • the rocker 19 because the rocker 19, as mentioned, has lever arms 22 and 23 of different lengths, it can be ensured that the solenoid 11 only needs to develop relatively small forces to hold the actuating member 2 in its standby position and therefore only needs to be energized weakly. If, for example, the long lever arm 23 of the rocker 19 is five times longer than the short lever arm 22, then the holding force which the solenoid 11 has to apply in order to hold the actuating element 2 in its standby position is five times less than the spring force which the main Spring 3 applies and with which the main spring 3 tries to push the actuator 2 from its standby position into its release position.
  • the long lever arm 23 is at least a factor of 2, ideally at least a factor of 3, longer than the short lever arm 22.
  • the threaded spindle 20 preferably has a pitch which gives it self-locking. This means that the threaded spindle 20 does not begin to rotate automatically under the influence of the force of the main spring 3 acting via the actuating element 2, even when the electric motor 6 is de-energized.
  • the Figure 6 shows an alternative third exemplary embodiment for the trigger 1 to be used according to the invention.
  • the special feature of this exemplary embodiment is that the first electromagnetic actuator 4 and the second electromagnetic actuator 5 coincide, that is, only a single electromagnetic actuator is required. This realizes both the function of the first electromagnetic actuator and the function of the second electromagnetic actuator, which are provided separately from one another in the other exemplary embodiments.
  • an actuating member 2 is also present in this exemplary embodiment, which is held in its standby position against the tension or force of the main spring 3.
  • An electric motor 6 is again provided here as the only actuator.
  • the threaded nut 24 is designed in such a way that it can act positively on the actuating member 2.

In that by the Figure 7 The case shown, the actuator 2 of the trigger 1 pushes the brake wedge 30 upwards.
  • the brake wedge 30 Since the brake wedge 30 is provided with an inclined guide device 32, it thereby comes into contact with the guide rail. As soon as the brake wedge 30 is pressed against the guide rail with sufficient normal force, such a high frictional force arises between the guide rail and the brake wedge 30 that the brake wedge 30 is thereby driven deeper into the wedge gap. This has the effect that the brake wedge 30 and the counter brake lining 31, so to speak, clamp the guide rail between them. To this In this way, the car is first braked heavily and then the car is caught.
  • the trigger 1 to 4 is the type described (which is not absolutely necessary, the trigger in the Figures 5 and 6 described type can also be used here), then one can easily understand that the electric motor 6, due to the fact that it does not act directly on the actuator, but with a strong translation through the converter in the form of the spindle drive 7 and the holding tube 13 on the Actuating member 2 is able to retract the brake wedge even if it has been driven into the wedge gap with a relatively high force.
