Definitions

  • the invention relates to a device for preventing uncontrolled acceleration of a car of an elevator installation both in the upward direction and in the downward direction.
  • a car In elevator systems, a car is usually connected via a cable and a drive pulley, via which the drive takes place, with a counterweight.
  • a corresponding safety device is prescribed. Since the counterweight is usually designed to balance at half the allowed payload of the car, uncontrolled acceleration may occur in both the downlink and uplink depending on whether the halfway payload of the car has been exceeded or undershot. The safety device must therefore respond both in an uncontrolled acceleration in the downward direction and in the upward direction.
  • An apparatus for preventing uncontrolled accelerations of a car in an elevator system is for example from the EP 0 440 839 A1 known.
  • the resulting from this document safety device responds both in an uncontrolled acceleration in the downward direction and in the upward direction.
  • a governor rope independent of the drive cable is provided, which circulates endlessly over an upper deflecting roller and a lower deflecting roller. At the lower pulley weight is provided to keep the governor rope always taut. At the upper pulley there is a speed limiter.
  • the car is connected via a trigger serving as an actuating lever with the governor rope, so that the governor rope is always carried along undisturbed moving the car with this and thus the rotational speed of the upper pulley speed of the car is proportional.
  • the speed limiter detects the rotational speed of the upper guide roller and is designed so that it blocks when exceeding a limit rotational speed of the upper guide roller, so that the upper guide roller is stopped. Since the governor rope is still carried along with the elevator car, the governor rope slips over a groove provided in the upper deflecting roller and experiences a frictional resistance, so that a release force is transmitted to the trigger of the braking device via the governor cable. Then the brake device responds and presses brake shoes against a guide rail of the elevator system, so that the car is decelerated and intercepted. In this case, different brake shoes for braking or interception of the car in the downward direction or upward direction are provided.
  • the force acting on the cable strand of the governor rope connected to the trigger is to a considerable extent dependent on whether the car moves in the downward direction or in the upward direction.
  • the wire rope of the governor rope connected to the trigger pulls directly upwards against the weight of the lower deflection roller.
  • pulls connected to the trigger wire rope of the governor rope on the stationary upper pulley on the weight of the lower pulley so that in this case the force acting on the cable connected to the cable strand force increases significantly due to friction.
  • the dimensioning of the securing device in particular the weight associated with the lower deflection roller and the geometry of the keyway provided on the upper deflection roller, over which the governor rope is pulled when the upper deflection roller is stopped, must therefore be oriented towards the braking action of the elevator during the upward movement because in this case the release force is lower.
  • this means that the release force is so great in a downward movement of the car that considerable problems in the dimensioning of the governor rope and the trigger of the braking device occur because the governor rope and the trigger must withstand this very high release force in the downward direction.
  • the invention has for its object to provide a device for preventing uncontrolled accelerations of a car of an elevator system, in which the initiated in the trigger of the braking device release force is limited.
  • the trigger of the braking device with the governor rope via a slip connection so that the governor rope slips on the slip connection when a force is transmitted from the governor cable to the trigger of the braking device, which is considerably larger than that required to trigger the braking device Triggering force is.
  • the components of the device can be designed so that on the one hand a sufficient release force is generated to intercept an acceleration of the car in the upward direction to safely trigger the trigger of the braking device, on the other hand, however, the triggering force is limited in a trapping of the car in the downward direction, which prevents an overload of the trigger and the limiter rope.
  • the slip connection can be adjusted so that the governor rope slips on the slip connection only when braking the car in the downward direction.
  • the governor rope slips over the fixed upper deflection roller as before, without triggering the sliding connection according to the invention. Since the governor rope as described when braking the car in the downward direction a much larger force acts as when braking in the upward direction, it is sufficient that the slip slip through in the downward direction. In this case, the slip connection can be adjusted with some safety distance above the release force required for triggering the braking device.
  • the slip connection can be arranged directly below the cable connector, which connects the free ends of the governor rope together.
  • the slip connection preferably consists of a base plate and a biased against the base plate with a predetermined clamping force clamping plate, wherein the Beskyrseil is clamped between the base plate and the clamping plate.
  • At least one clamping screw which passes through a hole in the clamping plate and can be screwed into a thread of the base plate.
  • the screwing depth and thus the clamping force is limited by a clamping stop.
  • the clamping force can be generated from a clamped between the base plate and a projection of the clamping screw tension spring, which preferably consists of a plurality of stacked disc springs.
  • the clamping stop can be formed by a sleeve surrounding the clamping screw.
  • the limiter rope is preferably guided on a surface of the base plate and / or the clamping plate in a groove, which has a preferably triangular cross-sectional contour.
  • the groove preferably opens in an opening region which opens both in the direction of the surface and also transversely to the surface of the base plate or the clamping plate.
  • the trigger of the braking device is connected to either the clamping plate or the base plate.
  • FIG. 1 shows the device according to the invention for preventing uncontrolled acceleration of a car of an elevator installation, initially in an overall representation.
  • the support frame 2 of the car 1 is guided on an upper guide 3 and on a lower guide 4 on a guide rail 5 only indicated by the dashed line along a vertical trajectory.
  • the car 1 is suspended from a conveyor rope, not shown, which is deflected at the upper end of the elevator shaft via a drive pulley and connected to a counterweight.
  • the car is driven by the drive pulley.
  • the counterweight is usually sized so that the counterweight with the car 1 is then in equilibrium when the car 1 is subjected to about half its maximum payload. In the event of a malfunction, in particular in the event of a failure of the drive device, the car 1 can be accelerated uncontrollably due to the weight difference between the car 1 and the counterweight.
  • a braking device 6 which controls the uncontrolled acceleration in both upward and downward prevented in the downward direction and can be triggered via a trigger 7.
  • a braking device of a similar type is for example from the DE 296 19 729 U1 and the EP 0 825 145 A1 known and will be described only roughly.
  • the trigger 7 consists of a hinged to a suspension 8 rocker arm 9 and connected to the rocker arm 9 linkage 10 which engages a mounted on a bearing 11 turntable 12.
  • the linkage 10 When tilting the rocker arm 9 in Fig. 1 upwards, the linkage 10 is moved upward and rotates the turntable 12 so that a first brake element 13 is pressed into contact with the guide rail 5 only indicated, so that the guide rail 5 between a brake shoe 14 and the first brake element 13 is clamped.
  • the clamping force is determined by two acting on the brake shoe 14 disc spring assemblies 15 and 16.
  • the deceleration of the car 1 is then carried out by chip removal on the only indicated guide rail 5.
  • the above-described braking process concerns the braking of the car 1 in an uncontrolled acceleration in the downward direction.
  • the limiter rope 18 is formed in the embodiment as an upper guide roller 19 and a lower guide roller 20 endlessly circulating rope.
  • a linkage 22 which is articulated to a bearing 23, on the lower pulley 20 acting weight 21, the governor rope 18 between the upper guide roller 19 and the lower guide roller 20 taut.
  • the free ends 24 and 25 of the Beskyseils 18 are connected to each other via a cable connector 26.
  • a speed limiter 27 which stops the upper guide roller 19 when a predetermined rotational speed is exceeded, d. H. blocked.
  • Such speed limiter 27 are known in different designs.
  • the governor rope 18 is carried along with the car 1 uniformly and the upper deflecting roller 19 is in its unlocked state. Since the speed of the governor rope 18 corresponds to the speed of the car 1, the rotational speed of the upper deflecting roller 19 is proportional to the speed of the car 1. If the rotational speed of the upper deflection roller 19 exceeds a predetermined limit value, the speed limiter 27 blocks the upper deflection roller 19 so that the governor rope 18 is in sliding contact with the stopped upper deflection roller 19. Thereby, a force component is exerted on the governor rope 18, which transmits it to the trigger 7 of the braking device 6, which finally leads to the triggering of the braking device 6.
  • a cable weight G s attributable to this strand acts on both the left strand 18 a and the right strand 18 b of the limiter rope 18.
  • the governor rope 18 is pulled in this case to the left over the upper guide roller 19.
  • the right-hand force on the fixed upper guide roller 19 is given by the resultant force S 1 , which is composed of the cable weight G s and the force G / 2.
  • On the left strand 18a of the governor rope acts a correspondingly larger force S 2 , which is increased by the friction on the groove of the upper guide roller 19 accordingly.
  • a triggering force for the triggering of the braking device 6 is a vectorially downwardly acting force F 1 exploitable, resulting from the difference between the force S 2 and acting in the opposite direction rope weight G s and the force G / 2.
  • Fig. 11 illustrates the conditions when braking the car 1 in the upward direction.
  • the governor rope 18 is pulled to the right over the fixed, upper deflection roller 19. Accordingly, the right-hand force S 1 is greater than the left-side force S 2 on the upper guide roller 19. As a result, therefore, results in a vectorially upward force F 2 on the left strand 18a of the Beskyrseils 18, which is used as a triggering force for the braking device 6 ,
  • the force acting on the lower pulley 20 weight G and the ratio between the forces S 1 and S 2 determining geometry of the groove of the upper guide roller 19 must be dimensioned so that when braking the car 1 in the upward direction, the available release force F 2nd is still sufficient to safely trigger the braking device 6. Inevitably, this results in a slowing down of the car 1 down a much larger release force F 1 , as Fig. 10 illustrates.
  • the weight G of the weight 21 acting on the lower deflection roller 20 is calculated first by a predetermined amount To obtain triggering force in the upward direction F 2 , and one sets the determined in this way required weight G in the equations (1), (2) and (3), we obtain the downward effective release force F 1 as a function of the above effective release force F 2 .
  • the present invention proposes to connect the trigger 7 of the braking device 6 with the limiter rope 18 for limiting the force transmitted to the trigger 7 via a slip connection 30.
  • the governor rope 18 slips on the slip connection 30 by, when the limiter rope 18 on the trigger 7, a force is transmitted, which is considerably greater than the triggering force required for triggering the braking device 6. If the required release force is, for example, 400N, then the slip connection 30 can be adjusted so that it slips through, for example, 800N. This provides a sufficient safety margin from the required trigger force of 400N and limits the otherwise down tripping force from 1550N to said 800N.
