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 elevator system has a first elevator car and a second elevator car, which can be displaced in the vertical direction in a first elevator shaft. It also has a self-contained suspension element guided around a lower deflection roller and an upper deflection roller, a drive machine assigned to the suspension element, a controllable coupling device arranged on the first elevator car and a controllable coupling device arranged on the second elevator car.
  • the suspension element has a first and a second coupling element to which a coupling device of an elevator car can be coupled and uncoupled, with which a drive connection between the respective elevator car and the suspension element can be established and released.
  • a coupled elevator car 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 two coupling elements of the suspension element are arranged in such a way that when the first elevator car, which is coupled to the suspension element via a coupling element, is displaced from a lower end position to an upper end position or vice versa, no coupling element of the suspension element is guided around a deflection roller.
  • the arrangement according to the invention of the coupling elements on a suspension means allows the drive machine assigned to the suspension means to be controlled in such a way that a coupling element is never guided around a deflection pulley during operation of the elevator system.
  • the elevator shaft is arranged in or on a building and runs mainly in the vertical direction, so that when the elevator cars are moved in the elevator shaft, they are mainly moved vertically. Said first and second elevator cars do not have to be displaceable in the first elevator shaft at the same time. In particular, it is possible for the first elevator car to be displaced in the elevator shaft first and then the second elevator car to be displaced in the elevator shaft, in particular in the same direction. For this purpose, the first elevator car is removed from the elevator shaft, in particular before or during the displacement of the second elevator car.
  • the support means is self-contained, that is to say, for example, is designed in the shape of a ring. It can thus also be described as endless. However, this does not necessarily mean that it consists of a homogeneous ring or just one piece.
  • the suspension element is guided around a lower and an upper deflection roller, 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.
  • the deflection rollers are in particular arranged in such a way that their respective axis of rotation is perpendicular to an adjacent shaft wall of the elevator shaft.
  • 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 controller controls the entire operation of the elevator system, ie 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 cars are arranged in particular on a floor or a roof of the elevator cars and are controlled by the elevator control mentioned above.
  • the coupling to a coupling element of the suspension element 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.
  • 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, so that the elevator car is also displaced when the propellant is displaced or moved.
  • 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 such a way that, at least during the displacement of an elevator car, only one elevator car is coupled to a (single) suspension element. Only one (single) elevator car is shifted in the shaft by a (single) suspension element.
  • the two coupling elements of the suspension element are arranged in such a way that when the first elevator car, which is coupled to the suspension element via a coupling element, is displaced from a lower end position to an upper end position or vice versa, no coupling element comes into contact with a deflection roller. This means that the coupling element does not touch the deflection rollers. A deflection roller cannot be damaged by a coupling element or vice versa.
  • This arrangement of the coupling elements on a suspension means allows the drive machine assigned to the suspension means to be controlled in such a way that a coupling element never comes into contact with a deflection pulley during operation of the elevator system.
  • the support means can therefore always be stopped in good time for the coupling elements never reach the deflection rollers or, for example, maintain a certain minimum distance from the deflection rollers.
  • the two coupling elements of the suspension element are arranged in such a way that when the first elevator car, which is coupled to the suspension element via a coupling element, has reached the upper end position during an upward displacement, the other coupling element is positioned in such a way that the one assigned to the second elevator car moves Coupling device arranged in the lower end position of the second elevator car can couple to the other coupling element.
  • the other coupling element is accordingly positioned when the first elevator car reaches the lower end position such that the coupling device of the second elevator car arranged in the upper end position can couple to the other coupling element.
  • the second elevator car can be coupled to a coupling element at the other end position and thus prepare for the displacement of the second elevator car.
  • the uncoupling of the first elevator car and the coupling of the second elevator car can take place at least partially simultaneously, with the result that an effective operation of the elevator system is made possible.
  • the drive machine is controlled by an elevator controller.
  • This is intended to reverse a direction of movement of the suspension element for the next displacement of an elevator car when an elevator car has reached the lower end position or the upper end position, depending on the direction of displacement. It is thus advantageously possible to move both elevator cars of the elevator system in the same direction in the elevator shaft without a coupling element being guided around a deflection roller or coming into contact with a deflection roller during operation of the elevator system.
  • the elevator control is thus intended to move the elevator cars in the elevator shaft only in one direction, ie only from bottom to top or only from top to bottom.
  • the elevator system has at least one additional suspension element with two coupling elements arranged spaced apart from one another in the vertical direction and another drive machine assigned to the additional suspension element.
  • the coupling elements are like those already described Carrying means arranged.
  • the support means are arranged parallel next to one another in the elevator shaft.
  • the elevator control is provided in particular to control the two drive machines of the suspension elements independently of one another.
  • a further elevator car can thus be shifted in the elevator shaft with a second suspension element at the same time as the first elevator car and independently of the first elevator car.
  • the elevator system can thus be operated particularly effectively and many passengers can be transported in the building, in particular with different destination floors.
  • the elevator system has more than two, in particular four, such suspension elements. It is also conceivable that the elevator system has more than four such suspension elements.
  • the coupling devices may be able to couple to the coupling elements of the various suspension elements.
  • the coupling devices are then arranged to be displaceable horizontally, in particular transversely to their direction of actuation.
  • the coupling device is first displaced transversely to its direction of actuation in such a way that it is correctly positioned in relation to the coupling element of the corresponding suspension element.
  • the coupling to the suspension element can then take place, in particular by extending the bolt of the coupling element.
  • a correspondingly positioned coupling device to be provided on the elevator car for each suspension element.
  • a coupling element of each suspension element is designed as a connecting element which connects two free ends of suspension element parts to one another.
  • the coupling element can thus advantageously fulfill a dual function, namely, on the one hand, the coupling of an elevator car and, on the other hand, enable a closed suspension element.
  • the coupling element fulfills the function of a so-called belt lock or a cable connector. This means that it is very easy, inexpensive and safe to get through from an open, elongated suspension element part Connecting the two free ends to the coupling element, a self-contained suspension means can be produced.
  • the suspension element thus consists of two suspension element parts, the free ends of which are connected by means of a primary coupling element and a secondary 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.
  • both coupling elements of each suspension element are designed as connecting elements.
  • a suspension element of the elevator system according to the invention thus consists of two open, elongated suspension element parts and two coupling elements designed as connecting elements, which each connect two free ends of different suspension element parts to one another.
  • the coupling elements are designed identically. This enables the use of as many identical parts as possible, which on the one hand enables lower production costs and on the other hand makes assembly easier since all coupling elements can or must be assembled in the same way.
  • the suspension means are designed as belts.
  • Belts have excellent traction properties and are particularly suitable for interacting with controllable coupling devices.
  • the belts can be designed as flat belts, V-ribbed belts or toothed belts and can be reinforced with tensile reinforcements in the form of wire ropes, synthetic fiber ropes or synthetic fiber fabrics. In this way, an elevator car coupled to the suspension element can be shifted over a great height without impermissible vertical oscillations occurring.
  • suspension means may consist of one or more ropes, in particular wire parts.
  • the coupling elements are guided when shifted in the elevator shaft.
  • the guide used for this is designed in particular in such a way that it prevents the coupling elements from hitting a passing elevator car. This enables a particularly comfortable and safe operation of the elevator system.
  • an elevator car When an elevator car is relocated in the elevator shaft, it cannot be completely ruled out that the suspension element and thus the coupling element that is not connected to an elevator car will vibrate. Without a guide for the coupling element, there would in particular be a risk that the coupling element would hit the elevator car when driving past it. Such an impact would, on the one hand, lead to an audible impact and, on the other hand, could cause damage to the elevator car and/or the coupling element. This danger is avoided by guiding the coupling elements.
  • each elevator car has two coupling devices. These are intended to be coupled to the coupling elements of two different suspension means at the same time.
  • the drive machines of the two suspension elements are controlled in a synchronized manner, so that both suspension elements are driven and displaced synchronously.
  • the two coupling devices of an elevator car are arranged in particular on opposite sides of the elevator car. They are intended in particular to be coupled to a respective coupling element of a suspension element at diagonally opposite positions. This enables a particularly even or evenly distributed introduction of force into the elevator car, which allows the elevator car to tilt very little during the displacement.
  • this enables the elevator car to be moved comfortably and, on the other hand, guides in the elevator car are subjected to little stress, which makes a simple and more cost-effective design possible and also leads to very little wear.
  • compared to only one coupling device per elevator car only approximately half the force has to be introduced via a coupling device. This enables the use of cost-effective drive machines, which also only take up a small amount of space.
  • the two coupling devices are in particular not mechanically coupled, but are controlled accordingly by the elevator control.
  • the coupling devices are particularly like this when they are coupled to the two suspension elements positioned so that a connecting line runs through said center of gravity at the height of the center of gravity of the elevator car between the two coupling elements of the suspension means. This enables a particularly even introduction of force into the elevator car.
  • each elevator car can have only a single coupling device.
  • the elevator car can then only be coupled to one suspension means and be displaced in the elevator shaft by means of this.
  • the first and the second elevator car can also be displaced in the vertical direction in a second elevator shaft arranged parallel to the first elevator shaft.
  • the elevator system also has a first transfer device, by means of which elevator cars can be moved from the first elevator shaft to the second elevator shaft, and a second transfer device, by means of which elevator cars can be moved from the second elevator shaft to the first elevator shaft.
  • a relocation of the elevator cars in the second elevator shaft is implemented analogously to the relocation in the first elevator shaft.
  • the elevator cars are shifted only from bottom to top in the first elevator shaft and only from top to bottom in the second elevator shaft. It is not relevant which elevator shaft is designated as the first and which as the second elevator shaft.
  • the provision of the second elevator shaft and the two transfer devices advantageously enable circulating operation of the elevator system.
  • the transfer devices are arranged in particular in the area of the end positions of the elevator cars. If, for example, an elevator car reaches the upper end position when moving upwards in the first elevator shaft, then it after all passengers have left the elevator car and it has been uncoupled from the suspension means, is horizontally shifted to the upper end position of the second elevator shaft by means of the upper transfer device. It can then be coupled to a suspension element in the second elevator shaft and thus be shifted downwards in the second elevator shaft to the lower end position. From there it is in turn shifted horizontally by the lower transfer device into the lower end position of the first elevator shaft, from where it can be shifted back up. In this case, in particular, several, for example four, elevator cars per elevator shaft can be shifted simultaneously, with only one elevator car ever being coupled to a suspension element. This enables a particularly effective operation of the elevator system.
  • the transfer facilities can in particular according to the transfer facilities in the form of horizontal displacement units EP 2219985 B1 be executed.
  • the transfer device has a vertical guide rail piece that guides the elevator car in the transfer device.
  • the transfer device can be positioned in such a way that the guide rail piece forms a section of a vertical guide rail by which the elevator car is guided during displacement in an elevator shaft.
  • the elevator car then has a braking device with which the elevator car can be temporarily fixed to the guide rail piece integrated in the transfer device during displacement between the elevator shafts.
  • the same number of suspension elements, each with two coupling elements are arranged in the first elevator shaft and in the second elevator shaft.
  • a maximum number of elevator cars is the same size as a total number of suspension elements of the elevator system.
  • the number of elevator cars is exactly the same as the total number of suspension elements. This means that the number of coupling elements per elevator shaft is greater than or equal to the number of elevator cars to be shifted in an elevator shaft.
  • each elevator car in each of the two elevator shafts can be assigned a specific coupling element or, if coupled to two suspension elements at the same time, two coupling elements, with the respective coupling elements being arranged in the same position in the two elevator shafts.
  • an elevator car is coupled via its coupling device exclusively to the coupling element or elements assigned to it.
  • Each elevator car therefore requires only one coupling device or, in the case of simultaneous coupling to two coupling elements, only two coupling devices which are each arranged at a fixed position.
  • the coupling devices are thus not displaceable transversely to the direction of actuation of the bolt of the coupling devices. This enables the coupling devices to be implemented in a cost-effective manner.
