Definitions

  • the invention relates to an elevator system having the features of the preamble of claim 1.
  • the EP 2219985 B1 describes an elevator system with two elevator cars that can be displaced in a vertical direction in an elevator shaft, a self-contained suspension element guided around a lower deflection roller and an upper deflection roller, a drive machine in the form of an electric motor assigned to the suspension element, and a controllable coupling device arranged on each elevator car.
  • the support means has several coupling elements, which can be designed as holes or cams, for example.
  • a coupling device of an elevator car can be coupled to and uncoupled from a coupling element, with which a drive connection between the respective elevator car and the suspension element can be established and released.
  • An elevator car coupled to a suspension element can thus be displaced in the first elevator shaft by means of the suspension element that can be driven by the respective drive machine.
  • the elevator cars are only moved in one direction in the named elevator shaft, ie only upwards or only downwards.
  • the elevator system has an additional elevator shaft.
  • the elevator cars can be moved horizontally between the two elevator shafts by means of a transfer device.
  • an elevator car is coupled to a suspension element at a lower or an upper end position via its coupling device and a coupling element and is displaced upwards or downwards by the associated drive machine via the suspension element until it reaches the upper or lower end position has reached.
  • There the elevator car is uncoupled from the suspension element and is horizontally shifted by a transfer device into the elevator shaft for the other direction of displacement into the other elevator shaft.
  • the described coupling elements of the suspension means can be connected to an elevator car via a coupling device.
  • This Coupling elements are referred to below as connected coupling elements.
  • the coupling elements can also not be coupled to an elevator car. These coupling elements are referred to below as free coupling elements.
  • both connected and free coupling elements are shifted in the elevator shaft.
  • vibrations in the suspension elements can occur.
  • the connected coupling elements are prevented from swinging by their coupling to an elevator car. Without suitable countermeasures, the free coupling elements would follow the vibrations of the suspension element. This could result in a free coupling element hitting an elevator car when driving past it, or in a free coupling element hitting the elevator shaft.
  • Such an impact could on the one hand lead to an audible impact and on the other hand could cause damage to the elevator car and/or the elevator shaft and/or the coupling element.
  • the elevator system has an elevator car that can be displaced in an elevator shaft, a suspension element running in the elevator shaft, a drive machine assigned to the suspension element, and a controllable coupling device arranged on the elevator cabin.
  • the suspension element has a coupling element to which the coupling device can be coupled and uncoupled, with which a drive connection between the elevator car and the suspension element can be established and released.
  • the coupled elevator car can be displaced in the elevator shaft by means of the suspension means that can be driven by the drive machine.
  • the elevator system has a guide system for guiding the coupling element when it is displaced in the elevator shaft.
  • the management system has a stationary guide compared to the elevator shaft and one with the Coupling element connected via a connection and guided along the guide.
  • the connection between the coupling element and the runner is designed in such a way that a relative movement between the runner and the coupling element is possible.
  • the mentioned connection can thus also be referred to as a flexible connection.
  • the guide system mentioned advantageously prevents a free coupling element from hitting an elevator car and the elevator shaft during displacement in the elevator shaft and thus enables particularly comfortable operation of the elevator system.
  • Connected coupling elements are firmly coupled to an elevator car and thus participate in all movements of the corresponding elevator car.
  • elevator cars When moving in the elevator shaft, elevator cars are usually guided along car guide rails, which can be aligned with respect to the guide of the coupling element. Nevertheless, the corresponding elevator car can shift and/or tilt relative to the guidance of the coupling element. Such displacements and/or tilting can be caused, for example, by uneven load distribution within the cabin.
  • the flexible connection of the coupling element to the runner according to the invention enables compensation for the described shifting and/or tilting of the elevator car and thus of the coupling element with respect to the guidance of the guide system of the coupling element. Since the elevator car can exert large forces on the coupling element during the described shifting and/or tilting due to its mass, damage to the guide system of the coupling element could occur without the compensation described. For example, the runner and/or the guide could be damaged, which could lead to failure of the elevator system.
  • the flexible connection of the runner to the coupling element according to the invention prevents such damage to the guide system of the coupling element and thus failures of the elevator system. In addition to particularly convenient operation, this also enables particularly reliable operation of the elevator system.
  • a guide that is stationary relative to the elevator shaft is to be understood as meaning that the guide is not movable in the elevator shaft.
  • the guide can be designed, for example, as a guide rail that is fixed, for example screwed, to a shaft wall of the elevator shaft. It is also possible that the guide is formed by the shaft wall itself. For this purpose, the shaft wall can have a special guide surface, for example.
  • the runner can also be referred to as a trolley.
  • the runner can have, for example, one or more guide rollers that roll on the guide and are thus guided by it. It is also possible for the runner to have a sliding surface along which the guide slides and is thus guided by it.
  • connection via which the runner is connected to the coupling element, can be designed, for example, as an axle in the form of a pin, which can be moved in at least one direction relative to the coupling element.
  • the mentioned relative movement between the runner and the coupling element has in particular at least one horizontal component. It is also particularly limited.
  • the elevator system has more than one elevator car, ie, for example, two to eight elevator cars, which are basically identical in structure and all have a coupling device.
  • the elevator system has more than one elevator shaft, specifically two elevator shafts, between which the elevator cars can be moved by means of transfer devices.
  • a transfer station is arranged at both ends of the elevator shafts, so that a circulating operation of the elevator cars is possible.
  • the elevator cars are shifted only from bottom to top in a first elevator shaft and only from top to bottom in a second elevator shaft. When the upper or lower end of the respective elevator shaft is reached, the elevator cars are moved to the other elevator shaft by means of a transfer station.
  • the elevator shaft or elevator shafts are arranged in or on a building and run mainly in the vertical direction, so that the elevator cars are mainly displaced vertically when they are moved in the elevator shaft.
  • the suspension element is in particular self-contained, that is, for example, designed in the shape of a ring. It can thus also be described as endless. However, this does not necessarily mean that it is designed as a homogeneous ring or consists of only one piece.
  • the suspension means is in particular a lower and an upper deflection roller out, with at least one deflection roller serving as a drive roller or traction sheave, via which the suspension element can be driven by the drive machine assigned to it.
  • the deflection rollers have an effective diameter of less than 100 mm. Such small effective diameters of a deflection pulley serving as a traction sheave enable a gearless drive of the suspension element, which requires little installation space.
  • a tensioning device can be arranged on the suspension element, with which on the one hand the required suspension element pretension is generated and on the other hand deviations in the original length of the self-contained suspension element and operational plastic length changes of the suspension element are compensated for.
  • the required tensioning forces can be generated, for example, with tensioning weights, gas springs or metal springs.
  • the drive machine is designed in particular as an electric motor that is controlled by an elevator controller.
  • the elevator control controls the entire operation of the elevator system, so it controls all controllable components of the elevator system and is connected to switches and sensors of the elevator system.
  • the elevator control can be designed as a single central elevator control or consist of several decentralized controls that are responsible for subtasks.
  • the coupling devices arranged on the elevator car(s) are arranged in particular on a floor or a roof of the elevator car and are controlled by the elevator control mentioned above.
  • the coupling to a coupling element of the suspension element in a coupled position of the coupling device takes place in particular in a form-fitting manner, with a friction-fitting coupling also being conceivable.
  • the coupling element has, in particular, a mainly horizontally oriented recess into which, for example, an extendable and retractable bolt of the coupling device can enter in an actuation direction. In this case, the coupling device is in its coupled position when the bolt of the coupling device enters the recess of the coupling element and in its uncoupled position when the bolt does not enter the recess.
  • a positive or frictional connection between the elevator car and the suspension element can thus be produced via the coupling device and the coupling element be so that with a shift or movement of the propellant and the elevator car is shifted.
  • a drive connection between the elevator car and the suspension element, and thus ultimately between the elevator car and the drive machine assigned to the suspension element, can thus be established and also released again.
  • the coupling devices are controlled in particular in such a way that, at least during the displacement of an elevator car, only one elevator car is coupled to a (single) suspension element. In particular, only one (single) elevator car is ever shifted in the shaft by a (single) suspension element.
  • a coupling element of a suspension element is designed in particular as a connecting element which connects two free ends of the suspension element to one another.
  • the use of a self-contained suspension means makes it possible to dispense with a counterweight that has to be guided past the elevator car, which allows for a small cross-section of the elevator shaft.
  • the coupling element designed in this way fulfills a dual function. On the one hand, it serves to couple the elevator car to the suspension element and, on the other hand, to realize the closed suspension element in a simple and cost-effective manner.
  • the coupling element fulfills the function of a so-called belt lock or a cable connector.
  • a self-contained suspension element can be produced very simply, inexpensively and safely from an originally open, elongated suspension element by connecting the two free ends with the coupling element.
  • the coupling element can, for example, have two suspension element end connections connected to one another, which, for example, correspond to EP 1634842 A2 can be executed.
  • the two suspension element end connections can be connected, for example, via an intermediate piece to which they can be screwed or welded, for example.
  • the coupling element can also have a one-piece housing.
  • the guidance of the guidance system runs along a shaft wall of the elevator shaft.
  • Said connection between the coupling element and the runner is designed in such a way that a first relative movement between the runner and the coupling element is possible with at least one component in the direction towards the said shaft wall and away from the shaft wall.
  • the named component of the direction runs in particular mainly perpendicularly to the shaft wall and thus mainly horizontally.
  • the relative movement mentioned runs in particular only towards the shaft wall and away from the shaft wall and thus in particular only perpendicularly to the shaft wall.
  • it can also have a component that is aligned along the shaft wall, that is to say running at an angle to the shaft wall or along a circular path.
  • the guide is designed in particular as a guide rail that is fixed to the shaft wall, for example screwed on.
  • the named direction of the component of the relative movement thus also runs in the direction of the guide rail and away from the guide rail.
  • the statements regarding the alignment of the relative movement with respect to the shaft wall thus apply analogously to an alignment of the relative movement with respect to the guide rail.
  • the relative movement also runs in particular in the above-mentioned actuation direction, in which a bolt of the coupling device can be extended and retracted for coupling to a coupling element.
  • a shaft wall should be understood to mean a delimitation of the elevator shaft in the horizontal direction.
  • a shaft wall is designed in particular as a solid wall, for example made of concrete.
  • a shaft wall it is also possible for a shaft wall to be formed solely from a plurality of crossbeams, to which, for example, car guide rails can be fixed. This can occur in particular when several elevator shafts are arranged next to one another and the individual elevator shafts are separated from one another by crossbeams.
  • connection between the coupling element and the runner has a pin which is coupled to the runner and in a recess in the coupling element in the direction of the said shaft wall and away from the shaft wall is arranged away slidably.
  • the pin can be fixed to the runner, for example screwed on. It is also possible that the runner is designed as a guide roller which is rotatably arranged on the pin. In addition, the runner can also have a lever which is pivotably arranged on the pin.
  • the recess is designed in particular as a through opening through which the pin protrudes.
  • the pin is secured against leaving the through-opening.
  • connection has a first spring arrangement, which is designed and arranged in such a way that it can apply a force to the runner in the direction of the first relative movement. Relative movements that occur between the rotor and the coupling element can thus be cushioned in the direction of the first relative movement. This enables the runner to be guided particularly smoothly.
  • the first spring arrangement has a first spring which pushes the runner away from the coupling element. This can prevent the rotor from bumping into the coupling element, which could cause annoying noises.
  • the first spring arrangement also has a second spring, which pulls the runner towards the coupling element. In this way, relative movements of the rotor away from the coupling element can also be cushioned.
  • a rest position of the runner can be set in the direction of the first relative movement, which the runner assumes when no other forces are acting on it, by appropriately designing the first and second springs.
  • the guide runs along a shaft wall of the elevator shaft.
  • the connection between the coupling element and the runner is designed in such a way that a second relative movement between the runner and the coupling element along the shaft wall mentioned has at least one horizontal component is possible.
  • the enabling of a second relative movement between the runner and the coupling element enables a particularly comfortable and reliable operation of the elevator system.
  • Said relative movement can, in particular, run horizontally and thus only have a horizontal component. It then runs mainly parallel to said shaft wall. However, it can also have a vertical component or run along a circular path.
  • connection between the coupling element and the runner is designed in particular in such a way that a first relative movement between the runner and the coupling element has at least one component in the direction of the shaft wall mentioned and away from the shaft wall and, in addition, a second relative movement between the rotor and the coupling element along the shaft wall mentioned has at least one component horizontal components are possible. However, it is also possible that only the first relative movement mentioned or the second relative movement mentioned is possible.
  • the guide guides the runner in the direction of the first relative movement and in the direction of the second relative movement between the runner and the coupling element. This enables a particularly reliable guidance of the runner and thus of the coupling element. This leads to a particularly comfortable operation of the elevator system.
  • Guidance of the runner in the direction of the first and second relative movement is to be understood here as meaning that the runner cannot be displaced or can only be displaced to a very limited extent with respect to the guide in the direction of the first and second relative movement. In the case of a vertically running guide, the runner can thus be displaced mainly only vertically.
  • said recess which at least partially accommodates the above-mentioned pin, is arranged on a swivel arm of the coupling element, which can be swiveled along said shaft wall. This allows the two relative movements described to be particularly simple and implement at low cost.
  • connection has a second spring arrangement, which is designed and arranged in such a way that it can apply a force to the runner in the direction of the second relative movement. Relative movements that occur between the rotor and the coupling element can thus be cushioned in the direction of the second relative movement. This enables the runner to be guided particularly smoothly.
  • the second spring arrangement has, in particular, a third and a fourth spring which act in opposite directions to one another.
  • a rest position of the runner can be set in the direction of the second relative movement, which the runner assumes when no other forces are acting on it.
  • the guide has a side cheek and the runner has a guide roller, the guide roller being guided on an inside of the side cheek of the guide.
  • a side cheek is to be understood as meaning a section of the guide which protrudes away from the shaft wall and into the elevator shaft.
  • the guide has in particular a first side cheek and an opposite second side cheek and the runner has a first guide roller and a second guide roller.
  • the first guide roller is guided on the inside of the first side cheek of the guide and the second guide roller on the inside of the second side cheek of the guide.
  • the guidance by means of two guide rollers enables a particularly good guidance of the coupling element and thus a particularly comfortable operation of the elevator system.
  • the first guide roller is mounted on a first roller axis and the second guide roller is mounted on a second roller axis.
  • the two roller axes are arranged on a lever of the runner that can be pivoted about a lever axis, with the two roller axes being in particular on the lever axis opposite sides of the lever are arranged.
  • the two guide rollers can be pivoted in the direction of the side walls of the guide or pivoted away from them.
  • the lever axis of the pivotable lever of the runner is at least partially formed by the above-described pin of the connection between the coupling element and the runner.
  • the pin thus has a dual function, which enables the rotor to be connected to the coupling element in a simple and cost-effective manner.
  • the runner has a third spring arrangement, which is designed and arranged in such a way that the guide rollers are pressed against the insides of the side walls of the guide. This ensures that the guide rollers always roll on the side walls of the guide and cannot detach from them. This enables a particularly good guidance of the coupling element and thus a particularly comfortable operation of the elevator system.
  • the third spring arrangement has a fifth spring and in particular an additional sixth spring, which are tensioned in particular between the lever of the runner and the coupling element in such a way that they press the guide rollers against the insides of the side walls of the guide. If there is a sixth spring, it acts in the same direction as the fifth spring.
  • the insides of the side walls of the guide have a concave contour and the guide rollers of the runner have a corresponding convex profile.
  • this ensures that the contact between the guide rollers and the guide is as large as possible, which enables particularly good guidance of the coupling element and thus particularly convenient operation of the elevator system.

  • Insides 92 of the side panels 91 have a concave contour.
  • the two guide rollers 85, 86 of the runner 82 have a corresponding convex profile on their outer circumference, so that the guide rollers 85, 86 move from the C-rail 83 in a first direction 93 towards the shaft wall 84 and away from it and in a second direction 94 are guided horizontally transversely to or along the shaft wall 84.
  • the runner 82 has a third spring arrangement 95 with an upper, fifth spring 96 (only in 6 visible) and a lower, sixth spring 79 (only in figure 5 visible)
  • the springs 96, 79 are tensioned between the lever 87 and the coupling element 46 in such a way that the guide rollers 85, 86 are pressed against the insides 92 of the side walls 91 of the C-rail 83.
  • the spring assembly 95 is the 7 shown more clearly.
  • the pin 97 is secured by a cap 100 screwed onto the end of the pin 97 opposite the runner 82.
  • the pin 97 can be displaced to a limited extent in the recess 98 in the direction of the shaft wall 84 and away from the shaft wall 84 . It can therefore be displaced in the first direction 93 mentioned above. A first relative movement between the rotor 82 and the coupling element 46 in the first direction 93 is thus possible.
  • a first spring 101 in the form of a coil spring is arranged around the pin 97 between the lever 87 of the rotor 82 and the pivot arm 99 .
  • the first spring 101 pushes the lever 87 and thus the runner 82 in the direction of the shaft wall 84.
  • a second spring 102 in the form of a helical spring is arranged around the pin 97 between the pivot arm 99 and the cap 100 of the pin 97.
  • the second spring 102 pushes the cap 100 of the pin 97 and thus the lever 87 and the runner 82 away from the wall 84 of the shaft.
  • the first spring 101 and the second spring 102 thus form a first spring arrangement 103 of the connection 81.
  • the pivot arm 99 having the through-opening 98 can be pivoted about a pivot axis 104 which runs parallel to the through-opening 98 and thus to the pin 97 .
  • the swivel arm 99 can thus perform a swiveling movement along a circular path around the mentioned swivel axis 104 and thus along the shaft wall 84 to a limited extent.
  • the possible movement of the swivel arm 99 thus has a horizontal component as well as a vertical one.
  • the lever 87 of the rotor 82 is also pivoted with the pin 97 relative to the pivot axis 104 and thus relative to the coupling element 46 .
  • the runner 82 When pivoting the pivot arm 99 about the pivot axis 104, the runner 82 thus performs a second relative movement with respect to the coupling element 46, which, as described, has a horizontal component.
  • a second spring arrangement 106 acts on the swivel arm 99, which is only 7 is shown.
  • the spring assembly 106 includes a third spring 107 between Pivot arm 99 and a vertically extending component 108 of the coupling element 46 is arranged so that the pivot arm 99 in the 7 pushes to the left.
  • the spring arrangement 106 also has a fourth spring 109 which is arranged on the side of the component 108 of the coupling element 46 facing away from the pivot arm 99 in such a way that it holds the pivot arm 99 in the 7 pushes to the right.
  • the third spring arrangement 95 is also clearly visible.
  • the upper, fifth spring 96 and the lower, sixth spring 79 are tensioned between the outwardly projecting hook 110 of the lever 87 and the vertical component 108 of the coupling element 46 in such a way that the guide rollers 85, 86 press against the inner sides 92 of the side walls 91 of the C Rail 83 are pressed.
