Definitions

  • the invention relates to an elevator according to the preamble of claim 1.
  • elevators are equipped with safety gears.
  • the cause of an impermissibly high acceleration of the car can be, for example, a malfunction of the control system of a drive or its brake or a rope break.
  • the detection of an impermissibly high speed and the subsequent necessary triggering of the safety gear is typically carried out with the aid of a so-called overspeed governor.
  • the pivot lever 42 is connected in a rotationally fixed manner to the synchronizing element 41, which is designed as a shaft.
  • This synchronizing element 41 transmits the pivoting movement of the pivot lever 42 to a second pivot lever 42 arranged parallel to this first pivot lever 42 (which is not shown in Fig. 2 ).
  • this problem is typically solved by means of a connecting member 43.
  • This connecting member 43 is connected, for example by a pin connection, to the pivot lever 42 and the clamping body in such a way that a rotational movement of the pivot lever 42 relative to the connecting member 43 is possible, as well as a rotational movement of the connecting member 43 relative to the clamping body.
  • This allows the pivot lever 42 to perform a purely rotational movement about the pivot axis 47, while the clamp body performs a purely translational movement with respect to the pivot axis 47.
  • the pivot lever 42 is positioned laterally next to the safety gear 3 and thus with some offset from the center of gravity of the clamping body.
  • the braking force (occurring at the first contact of the clamping body with the guide rail 46 at the clamping body, pulling it further into the wedge gap between the guide rail 46 and the safety gear 3).
  • to shear forces between the connecting member 43 and the clamping body as well as between the connecting member 43 and the pivot lever 42 These shear forces cause an increase in the already described sag of the pivot lever 42, which is not controlled by the activating element 48.
  • the arrangement of the pivot lever 42 with an offset with respect to the centre of gravity of the clamping body affects the rigidity of the structure and, consequently
  • US 2007/181378 A1 discloses the preamble of claim 1. It relates to an emergency stop system for an elevator.
  • a governor sheave that moves in synchronism with the raising and lowering of a car is wound around a governor sheave.
  • the car is mounted with a safety device for braking the car through displacement of the car, which is connected to the governor rope, with respect to the governor rope.
  • a control device outputs an activation signal upon detecting an abnormality in the speed of the car.
  • a rope catching device is provided in the vicinity of the governor sheave.
  • the rope catching device has an electromagnetic actuator that is activated upon input of the activation signal, and a restraining portion for restraining the governor rope upon the activation of the electromagnetic actuator.
  • the solution to the problem involves an elevator having a car and at least two safety gears mounted remotely from each other on the car and a preferably broadly understood overspeed governor - preferably exactly one overspeed governor.
  • the elevator comprises an activating element controlled by the overspeed governor to apply a brake actuation force in the event of overspeed, preferably in the form of a traction force.
  • This brake actuating force is transmitted to the safety gears via a synchronizing device for synchronous triggering.
  • the synchronizing device has a pivot lever for each safety gear.
  • the pivot lever is hinged at one end to the clamping body of the safety gear in a hinge area. On the opposite other side, it is connected to another pivot lever via a synchronizing element.
  • the other pivot lever is associated with another safety gear.
  • the elevator is characterized by the fact that a translatory movement relative to its pivot axis is superimposed on the pivot levers or their rotating movement. This translatory movement causes said hinge area of the respective pivot lever to perform a resulting movement that is translatory.
  • the resulting movement of the hinge area of the pivot lever regularly runs at least essentially parallel to the direction of insertion of the clamping body into the wedge gap assigned to it.
  • the two pivot levers are ideally connected to each other indirectly via one or more further elements of the synchronizing device, so that the two pivot levers together with the safety gears controlled by them can be arranged on two opposite sides of the car. This ensures a uniform application of force to the car during the triggering of the safety gears.
  • the "car” is understood to be either an essentially non-self-supporting car which is accommodated in a supporting sling, i.e. a supporting frame, or a car with an integrated car frame, the integration of which replaces the sling, or simply a platform which can be moved in the shaft for parking the goods to be transported.
  • “Hinged” means a connection that allows the pivot lever on the clamping body to make the movement required to engage the brake.
  • the “hinge area" of the pivot lever is the section of the pivot lever via which it is connected to the clamping body of the safety gear.
  • the hinge area thus corresponds to the section of the pivot lever in which the pin is arranged.
  • a synchronizing device which preferably has features according to the synchronizing device of an elevator according to the invention. It is used for synchronous triggering of a plurality of safety devices on an elevator car.
  • the synchronizing device is characterized by the fact that it has at least two pivot levers, each of which can be pivoted about at least one stationary pivot axis on the car.
  • the pivot levers act on at least two safety gears.
  • the safety gears are actuated by a synchronizing shaft which transmits essentially only torsion and is itself not translationally movable, the rotation of which controls the pivot levers.
  • the pivot lever is actuated by a coupling lever during triggering.
  • the pivot lever and the coupling lever also move translationally relative to each other in their coupling area during triggering.
  • the pivot lever and the coupling lever are coupled in that an axle pin of one of these levers is movably held in a straight slot of the other of these levers.
  • the pivot lever is designed in the form of a telescopic rod and the translatory relative movement is effected by the extension and retraction of the telescopic rod.
  • the generation of the translatory relative movement by means of an axle pin of one lever which is held in a straight slot of the other lever is advantageous, since the translatory mobility of the one lever is particularly easily advanced.
  • the length of the straight slot determines the maximum translatory freedom of movement.
  • the translatory relative movement of the two levers with respect to each other can also take place simultaneously with a pivoting movement of the two levers with respect to each other.
  • the axle pin 23 performs a movement composed of a rotational movement and of a translational movement. This is illustrated with reference to the arrows 54 and 55 in Fig. 7 . Since the axle pin 23 protrudes through a bore 36 of the pivot lever 18, the movement of the axle pin 23 is transmitted to the pivot lever 18.
  • the straight slot 12 is provided in the arm of the coupling lever 11. Although not preferred, there are also cases in which the straight slot 12 is instead provided in the torsion bar, in the area of one of its ends. Said straight slot causes the pivot lever 18 to perform both a rotational movement about its pivot axis 21 and a translational movement dictated by the movement of the axle pin 23. This is possible because the pivot lever 18 has an oblong hole 38 in the area where the pin 28, which predetermines the pivot axis 21 of the pivot lever 18, protrudes through the pivot lever 18. Relative to the pin 28, the pivot lever 18 thus performs both a translational movement and a rotational movement in the clockwise direction, as illustrated by the arrows 56 and 57 in Fig. 7 .
  • the pivot lever 18 is connected to the clamping body 4 of a safety gear 3 via an axle pin 25. This connection is such that the pivot lever 18 can rotate relative to the clamping body 4 about the axle pin 25, but otherwise imposes its movement on the clamping body 4.
  • This second pivot lever is actuated, in the same way as the first pivot lever 18, by a second coupling lever.
  • This second coupling lever performs the same movement as the first coupling lever 11.
  • the second coupling lever is not actuated by an activating element, although this would also be a conceivable embodiment of the synchronizing device 9 according to the invention.
  • the movement of the second coupling lever is generated by means of the synchronizing element 10 designed as a shaft.
  • the first coupling lever 11 is flanged to the synchronizing element 10 by means of two screws 32.
  • This causes the synchronizing element 10 to perform a rotational movement about the axis of rotation 13, which is also the longitudinal axis of the synchronizing element 10. Since the second coupling lever is flanged to the synchronizing element 10 in the same way as already the first coupling lever 11, this leads to a corresponding rotational movement of the second coupling lever, namely in synchronism with the rotational movement of the first coupling lever 11.
  • the second pivot lever is moved so that it engages the clamping body of the second safety gear with the second guide rail.
  • the synchronizing element 10 is secured to the car frame 2 by means of two tabs 24 such that it can perform a rotation about their longitudinal axis, but cannot perform a translational relative movement to the car frame 2 in or against the direction of movement of the car 2 along the elevator shaft.
  • a tension spring 26 is provided. This tension spring is attached at one end to the safety gear 3 and at its other end to one of the through bores 35 of the pivot lever 18.
  • the coupling lever 11 is connected to the activating element 8 by means of the screw 29.
  • the screw 29 is inserted both through the bore 31 of the activating element 8 and through the bore 30 of the coupling lever 11. Then it is screwed - mostly on the side of the coupling lever 11 facing away from the activating element 8 - with a nut.
  • the coupling lever 11 is connected to the synchronizing element 10 by screwing the screws 32 through the arc slots 17 into the bores 34 of the flange 33.
  • the coupling lever 11 is centred on the synchronizing element 10 by means of the shaft shoulder 52 forming a bearing seat, onto which the coupling lever 11 is pushed with its bearing eye 49.
  • the activating element 8 engages the first coupling lever 11 and not the first pivot lever 18, it is ensured that any sagging of the second pivot lever - if it occurs - can also be observed at the first pivot lever 18. Accordingly, even in the event that the pivot levers were to sag, the triggering of the safety gears would be synchronous. However, in the embodiment of the synchronizing device 9 shown, sagging of the pivot levers does not take place anyway, or only to a negligible extent. This will be explained below with reference to the first pivot lever 18.
  • the pivot lever 18 does not (mainly) rotate about the longitudinal axis of the synchronizing element 10 like the pivot levers known from the prior art, but about an additional pivot axis 21, the torque counteracting the pivoting movement of the pivot lever 18 is significantly reduced - i.e. the torque resulting from the dead weight of the pivot lever 18 and the weight of the clamping body 4.
  • the pivot axis 21 is allowed to move closer to the resulting point of application of the weight force, so that the lever arm is smaller.
  • the pivot arm 18 has a lesser tendency to counteract the rotational movement of the synchronizing element 10 or the coupling lever 11, which ultimately results in a significantly reduced sag of the pivot lever 18. This applies both to the first pivot lever 18 and to the second pivot lever opposite thereto.
  • the synchronizing device 9 can in principle also be used to trigger the safety gears when the car 2 moves upwards too quickly. For this purpose, it is only necessary to provide safety gears whose clamping body, starting from the initial position, can be brought into engagement with the guide rail both by a downward movement (relative to the rest of the safety gear) and by an upward movement. When such safety gears are used, the synchronizing device 9 can then be mounted so that the pivot lever 18 and the coupling lever 11 are arranged in their initial position such that their central longitudinal axes 22 and 14 are approximately coaxial with each other. Depending on whether the activating element 8 is then pulled upwards or downwards by the governor rope braked by the safety gear, the pivoting movement of the pivot lever 18 then takes place in clockwise or counterclockwise direction.
  • Such a pivot lever designed as a "lever cascade” is suitable for bridging a large distance between the safety gear 3 and the activating element 8 without at the same time causing a significant increase in the lever arm effect. This is of particular importance for suspension belt lifts, where larger distances naturally have to be bridged without having to build special safety gears for this purpose.
