Description
Technical Field
The invention relates to a switching device for an elevator installation.
Background
The switching device is provided for an elevator system having a movable guide rail section in the elevator system and comprises an electric motor for moving the movable guide rail section.
Such elevator installations are described in WO 2015/144781 a1 and DE 102016211
997a1 and DE 102015218025 a 1. Furthermore, devices are known in which the passenger cabin is transferred between the individual rails by means of a displacement mechanism.
The main advantage of such an elevator installation is that the transport capacity is significantly increased compared to conventional installations in which the elevator cabins always run in the same shaft. The use of two hoistways with the elevator installation described at the outset therefore makes it possible to provide the transport capacity of people which would be achieved in a conventional installation with five or more hoistways.
DE 10216205794 a1 discloses a switching device with a movable guide rail. The driving device of the conversion device is arranged between the guide rail and the well wall. In order to be able to place the guide rails as close as possible to the borehole wall, it is necessary to keep the axial installation space of the drive as small as possible. The drive is therefore designed without a gear mechanism.
Disclosure of Invention
It is an object of the present invention to provide an improved or alternative conversion device. The object of the invention is solved by a conversion device and an elevator installation according to the independent claims; various embodiments are subject matter of the dependent claims and the description.
The switching device according to the invention for an elevator installation comprises a movable, in particular rotatable, guide rail, a drive, in particular an electric drive, for moving, in particular rotating, the movable guide rail in a predetermined direction of movement. The drive is connected to the movable guide rail via a transmission. The transmission now provides the ability to decouple the position of the drive means from the position of the movable guide rail. This creates new degrees of freedom in positioning the components and optimizing space efficiency.
In one embodiment, the drive device has an output element which is provided for being driven in a predetermined drive direction as a function of the drive device, wherein the drive direction is different from the movement direction. In one embodiment, the output element may be an output shaft, wherein the drive direction is a rotational direction. In one embodiment, the output element can be a linear actuator, wherein the drive direction is the pushing direction.
In one embodiment, the drive and/or the gear mechanism are arranged outside the circle of rotation of the rotatable rails, in particular of all rotatable rails of the switching device. This allows the drive means and/or the transmission mechanism to be arranged radially offset with respect to the rotatable guide rail, which makes an arrangement between the rotatable guide rail and the borehole wall unnecessary. In this case, the drive and/or the gear mechanism can be arranged axially overlapping the rotatable guide rail. The rotatable track may be disposed as close to the borehole wall as possible without the need for a transmission or drive to further cooperate therebetween.
The switching device comprises in particular a bearing unit, in particular an axial bearing unit, which is provided for completely carrying the weight of the movable guide rail together with the weight of the car arranged on the movable guide rail.
In one embodiment, the switching device is provided for the movable guide rail to be movable to a predetermined maximum movement path, in particular to be rotatable by a maximum angle of rotation of less than 360 °.
The transmission may be a gear transmission, including a worm gear transmission, for example. Such a gear mechanism is characterized in particular by a high positional accuracy. Other means that can provide positional accuracy, such as in particular locking means, can be omitted as required.
Alternatively, the gear mechanism may be a traction mechanism gear mechanism, wherein in particular further measures are to be taken to maintain the positional accuracy. This can be achieved in particular by a lock which forces the movable guide rail into a predetermined position independently of the rough orientation predefined by the traction mechanism drive.
In one embodiment, the switching device comprises a hoist cable which is arranged at least partially outside the circle of rotation of the rotatable guide rail. The guide-rail-side end and/or the shaft-side end of the hoisting cable can be arranged outside the circle of rotation of the rotatable guide rail. The aforementioned optimization of the space efficiency can thereby also be achieved.
The elevator installation according to the invention comprises at least one fixed first guide rail which is fixedly oriented in a first, in particular vertical direction; at least one stationary second guide rail, which is fixedly oriented in a second, in particular horizontal direction; at least one switching device of the above-mentioned type. The two directions may be offset parallel to each other.

Detailed Description
Fig. 1 shows a part of an elevator installation 50 according to the invention. The elevator installation 50 comprises a fixed first guide rail 56 along which the car 51 can be guided by means of a rucksack support and which allows the car 51 to be movable between different floors. This arrangement of first guide rails 56, along which the car 51 can be guided by means of a backpack support, is arranged parallel to one another in two parallel extending hoistways 52', 52 ″. The first guide rail 56 is vertically oriented in a first z-direction z1 (first hoistway 52') or vertically oriented in a second z-direction (second hoistway 52 "). The cars in one of the hoistways 52' can move on the respective first guide rails 56 as independently as possible and without obstruction by the cars in the other hoistway 52 ".
The elevator installation 50 also comprises a fixed second guide rail 57 along which the car 51 can be guided by means of a backpack support. The second guide rail 57 is oriented horizontally in the y-direction and allows the car 51 to be movable within the floor. Furthermore, a second guide rail 57 interconnects the first guide rails 56 of the two hoistways 52', 52 ". The second guide rail 57 is therefore also used when the car 51 is switched between the two hoistways 52', 52 ", for example to perform modern bucket-type operation.
The car 51 can be transferred from the first guide rail 56 to the second guide rail 57 and vice versa via the third guide rail 58. The third guide rail 58 is movable in a manner to be rotatable about an axis parallel to the x-direction, which axis is perpendicular to the y-z plane enclosed by the first and second guide rails 56, 57. The movement is performed along a predetermined direction of movement B. The rotation of the third guide rail is performed by means of the drive device 2 shown in fig. 2 to 5. The third guide rail 58 and the drive 2 are part of the switching device 1.
All of the guide rails 56, 57, 58 are at least indirectly fixed at least one wall of the hoistway 52. The wall of the well defines a fixed reference frame for the position of the well. Alternatively, the term shaft wall also includes a stationary frame structure of the shaft, which carries the guide rails. A rotatable third guide rail 58 is fixed to the rotating platform 53. The rotating platform 53 is supported by means of a support unit 71.
A support unit 71, in particular an axial bearing support unit, is provided in order to fully carry the weight of the movable guide rail together with the weight of the car arranged on the movable guide rail.
Such a device is substantially described in WO 2015/144781 a1 and in german patent applications 102016211997.4 and 102015218025.5. In this respect 102016205794 a1 describes in detail an arrangement with an integrated bearing unit and an electric motor for rotating the rotary platform, which arrangement can also be used for bearing and as a rotary drive for the rotary platform within the scope of the invention.
Fig. 2 to 5 each show a conversion device 1 according to the invention. The drive devices 2 are each provided to drive a rotary movement of the rotatable rails 58. A transmission 60 is provided for transmitting the driving force to the rotatable rail. The output elements 69, 70 of the drive device 2 are moved in a drive direction a which differs from the movement direction B.
A form-fitting force transmission between the drive and the movable guide rail is in principle preferred, since in this case the rotational position of the drive 2 is oriented synchronously with the rotational position of the rotatable guide rail. This applies to all embodiments.
The drive means 2 are preferably arranged outside the circle of rotation D of the rotatable rail 58. An axial overlap between the drive device 2 and the rotatable guide 58 is thus achieved. Therefore, the axial structural space of the conversion device 1 can be reduced.
In the embodiment according to fig. 2, the gear mechanism is designed as a traction mechanism gear mechanism 60. The drive device 2 drives the drive shaft 61 in the drive direction a. The driven shaft 62 is driven by a traction mechanism 63 and is fixed to the rotatable guide rail 58. The traction mechanism 63 may be a chain or a belt.
In the embodiment according to fig. 3, the gear mechanism is configured as a gear mechanism 60. The drive device 2 drives a drive pinion 64 via an output shaft 70, which meshes with a driven pinion 65 fixed on the rotatable rail 58.
In the embodiment according to fig. 4, the gear mechanism is configured as a worm gear 60. The drive device 2 drives the worm wheel 66 through the output shaft 70, and the worm wheel 66 is engaged with the driven pinion 65 fixed to the rotatable rail 58.
In fig. 3 and 4, the transmission is a gear transmission. The drive with the gear mechanism is distinguished by significantly lower vibration dynamics than the embodiment with the traction mechanism gear mechanism according to fig. 2. This contributes to higher positional stability.
In the embodiment of fig. 2 to 4, the drive 2 is a rotary drive.
In the embodiment according to fig. 5, the drive 2 is a longitudinal drive and the gear is designed as a coupling gear 60. The drive device 2 drives a coupling rod 67 of the gear mechanism by means of an output rod 69, the coupling rod 67 being connected to the rotatable guide rail 58. Fig. 5a and 5b show the arrangement in two different rotational positions. Alternatively, the longitudinal drive 2 can also be replaced by a toothed rack which meshes with a driven pinion (similar to fig. 3)
Figures 6 and 7 show a conversion device with a possible arrangement of hoist cables 68. These illustrated devices may include the design of the drive mechanism described with reference to any of the preceding figures. The hoist cable 68 has a hoistway-side end 68a fixed to the hoistway and a rail-side end 68b fixed to the rotatable rail 58 and movable with the rotatable rail 58. The figures show the arrangement in different rotational positions of the rotatable rail 58.
In the embodiment according to fig. 6, the guide-rail-side end 68b is arranged within the circle of rotation D of the rotatable guide rail. Here, a radial overlap is required between the rotary platform and the hoist cable, so that a receiving space for receiving components of the hoist cable remains between the borehole wall and the rotary platform.
In the embodiment according to fig. 7, the hoist cable 68 is arranged outside the circle of rotation D. The hoistway-side end 68a and the guide rail-side end 68b of the hoist cable 68 are both disposed outside the circle of rotation D. Hoist cable 68 may be disposed entirely radially alongside rotatable rail 58.
