Definitions
- the invention relates to a speed limiter for an elevator installation, an elevator installation with a speed limiter and a method for limiting the speed of an elevator cage of an elevator installation.
- a speed limiter which monitors the driving speed of an elevator car.
- the overspeed governor operates as follows during operation.
- An elevator car drives a pulley of the speed limiter in a known manner via a wire rope, wherein a locking ring and a cam wheel are integrated into the pulley.
- a pendulum roller follows a path of the cam wheel.
- a retaining spring is set so that the spherical roller follows the cam of the cam wheel up to the nominal speed of the winding.
- the pendulum lever is displaced by the cams via the pendulum roller in oscillating movements with changing direction. If the winding speed exceeds a certain triggering value preset by the retaining spring, the pendulum roller lifts off the cam wheel.
- the moment of inertia of the pendulum lever is greater than the retention torque of the retaining spring.
- the pendulum nose remains immersed in the path of the ratchet, resulting in the blockage of the pulley.
- the force is built up to engage the safety gear.
- the object of the invention is to provide a speed limiter for an elevator installation, an elevator installation with a speed limiter and a method for a speed limiter of an elevator cabin, which are designed to be improved or simplified. Specifically, it is an object of the invention to provide a speed limiter for an elevator system, an elevator system with a speed limiter and a method for a speed limiter of an elevator system, in which a simple remote-controlled provision is possible in particular during a functional test, the direct presence of an operator, in particular of a test engineer, eliminating the speed limiter.
- the speed limiter includes a stator and a wheel rotatably mounted on the stator.
- the wheel is preferably connected by means of a release cable to an elevator car.
- a rotational speed of the wheel thus follows a travel speed of the elevator car.
- a mass body is moved according to a speed curve of the wheel and upon reaching a predetermined
- Rotational speed of the wheel pivots out of the mass body.
- this swinging the wheel of the speed limiter is braked, blocked or additional brake is operated.
- the tripping cable is braked, whereby, for example, a safety gear of the elevator car can be actuated.
- the switching flag can operate by pivoting a switch, which in turn interrupts, for example, a safety circuit of the elevator and stops the elevator.
- the speed limiter includes an actuator to operate the speed limiter.
- the actuating device is preferably from a distance, for example by means of a electrical signal operable. The actuator can swivel out the mass body together with the switching flag for the purpose of actuation and can bring it accordingly, for example, into engagement with the moving wheel. Thus, the switching flag is further pivoted and the switch is operated.
- the actuator is designed so that it again pivots the mass body together with the switching flag on re-actuation or in Weiderholung the operation and thereby resets the switching flag at a stationary wheel in the neutral pivot position.
- an actuating force of the actuating device is selected so that it does not prevent the pivoting of the switching flag, for example under the action of the engagement with the wheel.
- An actuating direction of the actuating device is identical in all operations.
- the switching flag is moved by the engagement with the rotating wheel. Since then, at a later resetting of the speed limiter, the corresponding movement of the actuator in the same direction of actuation, the wheel is stationary, thus exerts no force on the switching flag, can be reset by the same actuation the switching flag in its neutral pivot position.
- Such a speed limiter further includes a non-circular running surface which is rotatable with the wheel.
- the mass body is one, with respect to the stand, swiveling pendulum with a pendulum wheel resting against the running surface.
- a retaining device such as a spring, pulls the pendulum, or the pendulum, against the tread.
- the switch flag is connected to the pendulum.
- the tread no longer able to follow and it lifts off the tread.
- the pendulum, or a nose of the pendulum engages with a locking cam of the wheel in engagement.
- the switching flag is pivoted by the action of the locking cam from the neutral pivot position into the switching position, and thereby the switch is actuated.
- the preferably remotely actuable actuator is designed so that they can lift the swivel pendulum from the tread, if necessary, and can bring the pendulum with the switching flag in engagement with the locking cam.
- the switching flag is pivotable about a pivot point between the switching flag and the pendulum, that the actuating device acts in at least one engagement position of the switching flag, in which the switching flag with the locking cam is engaged, at least indirectly acts on the switching flag, that the Switch flag is pivoted back about the fulcrum in a neutral pivot position after the engagement between the switching flag and the locking cam is released.
- the actuating device can be remote-controlled.
- an actuation by the actuating device can be triggered, for example, from outside an elevator shaft in order to return the switching flag to the neutral pivot position.
- the switch which is actuated by the pivoting switching flag is a so-called latching switch.
- a latching switch maintains a switched position until it is reset by external action.
- the latching switch is also reset from a distance.
- This may for example be a latching switch with electromagnetic reset in which, for example, a magnetic holding force must be overcome during the operation and the means of an electromagnetic coil, even from a distance, can be reset. This prevents a multiple switching of the switch, which can occur, for example, because of a dynamic rebound of the pendulum in an actuation.
- an actuating element is provided and that the Actuation device acts on the actuating element for returning the switching flag in the neutral pivot position on at least one stop element of the switching flag.
- the stop element of the switching flag is designed as a nose.
- the switching flag can be made of a metal sheet, wherein the nose is configured by bending over a portion of the sheet. As a result, a robust and cost-effective production of the switching flag is possible.
- a stop element is provided at the pivot point between the pendulum and the switching lug, that the actuating device, in a functional test the switching lug from a neutral pivot position in which the pendulum of the pendulum is applied to the tread, via the actuator and the Stop element of the switching flag, which is provided at the pivot point, so actuated that passes through an at least substantially translational movement of the switching flag, the switching flag at a rotating wheel into engagement with a locking cam.
- the wheel is set in rotation by a suitable movement of the elevator car in the elevator shaft via the release cable.
- the switching flag, or the mass body, adjusted via the actuating device so that the switching flag comes into engagement with one of the locking cams of the rotating wheel. Then it comes to blocking the wheel and the friction of the triggering cable in a groove of the wheel, a release force can be transmitted.
- This release force can be transferred directly or indirectly to the safety gear.
- a trigger linkage of the safety gear can be moved, so that the safety gear of the elevator is engaged. This can be done especially when lowering the elevator car. Subsequently, it can be achieved by re-triggering the actuator again the provision of the switching flag in the neutral pivot position.
- the locking cam and the switching flag are designed so that the switching flag is pivoted about the pivot point between the switching flag and the pendulum when the switching flag arrives at a rotating wheel in engagement with one of the locking cam.
- the locking cam and the switching flag are designed so that the switching flag is pivoted in a first pivoting direction about the pivot between the switching flag and the pendulum when the switching flag at a rotating in a first direction of rotation in engagement with a locking cam passes, and is pivoted in a first direction opposite to the second pivoting direction about the pivot point between the switching flag and the pendulum when the switching flag opposite in one of the first direction of rotation second rotational direction of the rotating wheel engages with a locking cam, that upon pivoting of the switching flag in the first pivoting direction, a first stop element of the switching flag is pivoted closer to the actuating element as the stop element at the pivot point and that upon pivoting of the switching flag in the second pivoting direction second stop element of the switching flag is pivoted closer to the actuating element as the stop element at the pivot point.
- the actuator In a subsequent release of the actuator, the actuator is adjusted.
- the actuating element cooperates with the stop element, which is arranged closer to the actuating element than the stop element at the pivot point.
- the switching flag By the appropriate action on the switching flag, there is a pivoting, which is just opposite to the previous pivoting. As a result, the switching flag is pivoted back into the neutral pivot position, in which the engagement between the switching flag and the locking cam is released.
- the switching lug has a dovetail-shaped engaging portion, with which the switching lug engages with the locking cam, and that the locking cam has a contour adapted to the dovetail-shaped engagement portion.
- the dovetail-shaped engagement portion of the switching flag is moved when the actuating device is triggered via the actuating element into the cam ring of the rotating wheel, so that the dovetail-shaped engagement section comes into engagement with one of the locking cams. This is what happens
- the actuating device acts on the actuating element with a limited, predetermined actuating force.
- the predetermined actuating force can be applied by the magnetic force of a solenoid of the actuator.
- the actuating force is in this case limited so that a pivoting of the switching flag is made possible when the switching flag engages with the locking cam.

- Fig. 3 shows the speed limiter shown in Figure 1, wherein a release of the engagement between the switching flag and the locking cam is illustrated, and
- Fig. 4 is an elevator system with built-in speed limiter.
- the exemplary speed limiter 1 monitors the speed of the elevator car 41 via a pendulum principle.
- the speed limiter 1 has a stator 6 and a wheel 7, mounted rotatably about a bearing 7a on the stator 6. On the wheel 7, a groove 8 is configured, in which the triggering cable 5 is guided.
- the wheel 7 also has a non-circular running surface 9.
- the running surface 9 can in this case during a rotation of the wheel 7 at a circumferential location, which is fixed with respect to the stator 6, describe a wave-shaped movement in the radial direction.
- a pendulum 10 of a pendulum 11 which participates, caused by the tread 9, movement.
- the pendulum 11 is stored for this purpose in the stator 6 by means of a bearing I Ia. From a certain rotational speed, however, the pendulum wheel 10 lifts off from the tread 9, whereby the speed limit is effective.
- the pendulum 11 When turning the wheel 7 follows the pendulum 11 thus the tread 9 when the rotational speed remains below a predetermined value.
- the pendulum 11 is acted upon by the pendulum wheel 10 by a retaining force of a retaining device 12 against the running surface 9.
- the retaining device 12 is formed in this embodiment by a spring 12. If the rotational speed exceeds the value set by a bias of the spring 12, then the pendulum 11 lifts off with the pendulum wheel 10, whereby the switching flag 3 connected to the pendulum 11 is actuated.
- the spring can for example by means of a hole row provided in the stator 6 are individually biased. For better protection, the spring is covered by a protective cap during operation.
- Fig. 2 shows the speed limiter 1 shown in Fig. 1, wherein the switching lug 3 is in engagement with a locking cam 15 of the cam ring 4.

- the switch lug 3 can in this case actuate a switch 20.
- the switch 20 may be part of a safety circuit of the elevator installation 2, for example. By actuating the switch 20, the safety circuit can then be interrupted so that inter alia a motor of a drive machine unit 40 (see FIG. 4) can be switched off.
- Elevator shaft in particular a lowering of the elevator car 41, the trip bar is moved, so that the safety gear 42 of the elevator is engaged. As a result, the elevator car 41 is braked and stopped.
- the release force transmitted by the speed limiter 1 via the release cable 5 is sufficient to trigger the safety gear 42.
- This can For example, be triggered remotely at a certain nominal or test speed of the speed limiter 1. This is done via a fernauslösbare actuator 21, which may have an electric solenoid 21. While the elevator car is then traveling at the test or rated speed, the solenoid 21 pulls an actuating element 23 down in an actuating direction 24 via an actuating pin 22.
- a stop element 25a is provided at a pivot point 25 between the pendulum 11 and the switching lug 3.
- the adjusted in the direction of actuation 24 actuator 23 strikes against the stop element 25a and takes this in the direction of actuation 24 with.
- the switching flag 3 is taken in the operating direction 24, so that, starting from the position shown in FIG. 1, the engaging portion 19 engages with the locking cam 15 and the wheel 7 of the speed limiter 1 is blocked.
- the switch lug 3 which is rotatable about the fulcrum 25 on the stop element 25a, still actuates the switch 20.
- the position reached in this way is shown in FIG.
- the switch 20 can be electrically reset.
- the switch 20 can also be manually reset by hand.
- the switching flag 3 can be reset automatically in an advantageous manner. This is possible in this embodiment by a further triggering of the actuating device 21.
- the user friendliness can be improved, as it were, at the push of a button, both the switching flag 3 and, if necessary, time-delayed, the switch 20 can be reset.
- this can improve safety during operation.
- the speed limiter 1 is accommodated, for example, in the shaft head of an elevator shaft and thus directly accessible only from the roof of the elevator car, a comfortable and secure provision can be made remotely.
- the actuator 21 serves both to trigger the blocking of the speed limiter 1 in a test run and to reset the switching flag 3 and thus the speed limiter 1.
- both functions can be ensured by an actuator 21.
- the switching lug 3 has stop elements 26, 27, which are configured as lugs 26, 27.
- the lugs 26, 27 designed as bent portions of the switching lug 3.
- the stop element 25a at the pivot point 25 is at least approximately between the lugs 26, 27th
- the actuating element 23 has a strip-shaped arm 28 and a guide part 29. With the guide part 29, the actuating element 23 is guided on the actuating device 21 in and counter to the actuating direction 24. About the bar-shaped arm 28, the actuating element 23 depending on the pivot position of the switching flag 3 on at least one of the stop elements 25a, 26, 27 act.
- the bar-shaped arm 28 acts on the stop element 25a when actuated in the actuating direction 24, so that the switching lug 3 is displaced at least substantially in translation in the actuating direction 24.
- the wheel 7 When rotating the wheel 7 thereby enters the engaging portion 19 in the cam ring 4 and thus in engagement with the locking cam 15 or another locking cam 15a to 15g of the cam ring 4.
- the Switching lug 3 If, however, is assumed from the position shown in FIG. 2, in which the Switching lug 3 is engaged with the locking cam 15, and at the same time the triggering cable 5 is relieved, then acts upon actuation of the strip-shaped arm 28 of the actuating element 23 in the operating direction 24 of the strip-shaped arm 28 together with the nose 27 first. Because the nose 27 is in this case pivoted in a first pivoting direction 30 about the pivot point of the stop element 25a between the switching flag 3 and the pendulum 11, so that the
- Nose 27 is arranged closer to the strip-shaped arm 28 as the stop element 25a.
- the pivoting of the switching lug 3 is in this case carried out in that the wheel 7 is first rotated in a first rotational direction 31 until the switching lug 3 has come into engagement with the locking cam 15. The occurring collision causes the pivoting of the switching lug 3 in the first pivoting direction 30 about the pivot point 25 of the stop element 25a.
- the triggered by the actuator 21 striking the strip-shaped arm 28 on the nose 27 now causes a reverse pivoting of the switching flag 3 in a second pivoting direction 32 about the pivot point 25 of the stop element 25a, which is directed opposite to the first pivoting direction 30.
- the switching flag 3 enters a neutral pivot position, in which the engagement between the switching flag 3 and the locking cam 15 is released. Due to the restraining force of the spring 12 in this case the switching flag 3 via the pendulum 1 1 adjusted against the direction of actuation 24.
- the switching lug 3 is then again in a position as illustrated in FIG.
- the actuating device 21 is thus actuated for triggering and for resetting the speed limiter 1 or the switching lug 3 in the same or in the same operating direction 24.
- the actuating direction 24 thus remains identical. In the operation for resetting the speed limiter 1 thus the same operation as used to trigger the speed limiter 1 is repeated.
- Fig. 3 shows the speed limiter 1 shown in Fig. 1, wherein a release of the engagement between the switching flag 3 and the locking cam 15 is illustrated.
- the situation is shown in which the strip-shaped arm 28 of the actuating element 23 is adjusted by the actuating device 21 in the direction 24.
- the pivoting of the switching lug 3 is achieved in the second pivoting direction 32, as explained previously.
- the wheel 7 can, of course, initially also rotate in a second direction of rotation 32. If now the dovetail-shaped engaging portion 19 of the switching lug 3 comes into engagement with the locking cam 15, then the switching flag 3 is pivoted in the second pivoting direction 32 about the pivot point 25 of the stop element 25a. A reset can then also be done by triggering the actuator 21.
- strip-shaped arm 28 cooperates with the nose 26 to the switching flag 3, in the first pivoting direction 30 totechnischzuschwenken about the pivot point 25 of the stop member 25 in the neutral pivot position in which the engagement between the switching flag 3 and the locking cam 15 is released is.
- the provision of the switching flag 3 can be realized via the two stop elements 26, 27, which serve to reset.
- the switching flag 3 Upon activation of the speed limiter 1 is rotated or pivoted, the switching flag 3 with the two stop elements 26, 27 relative to the pendulum 11.
- the switching vane 3 in the first pivoting direction 30 or the second pivoting direction 32 is pivoted.
- one of the stop elements 26, 27 assumes a closer position on the strip-shaped arm 28 than the stop element 25a at the pivot point.
- the switching lug 3 Upon repeated actuation of the actuating device 21, the switching lug 3 is rotated by acting on the closer to the strip-shaped arm 28 stop member 26, 27 back to the starting position, ie the neutral pivot position.
- the switching flag 3 is designed so that the switch 20 is always actuated when the switching flag 3 is not in the neutral pivot position.
- the switch 20 is always actuated when the switching flag 3 is pivoted in the first pivot direction 30 or in the second pivot direction 32.
- the switch 20 can also be designed as a push-button 20 and automatically return to its closed position when the switching lug 3 returns to the neutral pivoting position.
- the position shown in FIG. 1 corresponds to a non-energized lifting magnet, while the position shown in FIG. 3 corresponds to an energized lifting magnet.
- the operating force of the actuator 21 is suitably limited. This takes into account that for triggering the speed limiter 1, the strip-shaped arm 28 first acts on the stop element 25a in the operating direction 24 and shortly thereafter due to the rotating wheel 7 and the successful stop on the locking cam 15, each opposite to the direction of actuation 24 upwards Nose 26, 27, the strip-shaped arm 28 can beat away from the stop element 25 a, as shown in FIG. 2.
- the actuating force of the actuating device 21 is therefore limited so that a pivoting of the switching lug 3 is made possible when the switching lug 3 comes into engagement with the locking cam 15. In this case, damage to the actuator 21 is prevented.
- a spring element 35 is provided, which acts on the actuating element 23, against the actuating force of the actuating device 21. As a result, a permanent abutment of the strip-shaped arm 28 on at least one of the stop elements 25a, 26, 27 avoided, as shown in FIGS. 1 and 2.
- the triggering of the actuating device 21 can take place via a separate control device 36.
- the separate control device 36 is in this case connected in a suitable manner to the actuating device 21.
- the control device 36 can also be arranged at a distance from the speed limiter 1 for the remote control of the actuating device 21.
- the control device 36 may be arranged outside a lift shaft.
- the control device 36 may in this case also be integrated in an elevator control.
- an additional connection of the control device 36 can be saved with the switch 20 when the switch 20 is designed as a button.
- the control device 36 may also be connected to the switch 20, for example, to allow only an explicit provision of the switch 20.
- both sides of a contour 39 of the locking cam 16 are adapted to the dovetail-shaped engagement portion 19 of the switching flag 3 and of course the pendulum nose 18.
- the pendulum wheel 10 of the pendulum 11 which abuts the non-circular running surface 9 of the wheel 7, be acted upon with a retaining force against the tread, wherein the connected to the pendulum 11 Switch lug 3, at a certain pivoting out of the pendulum 11, in which the pendulum wheel 10 lifts from the tread 9, with a locking cam 15 engages, which is connected to the wheel 7, and wherein the operation of the switch lug 3 by means of the actuator 11 the switching flag 3 is returned to its neutral switching position.
- a regular check of the functionality of the speed limiter 1 can be done in an improved manner.
- the device can also be adapted to a speed governor with mass bodies in the form of centrifugal weights, instead of the described pendulum.
