Description

Elevator installation

Technical Field

The invention relates to an elevator installation.

Background

DE 102014220966 a1 discloses an elevator installation in which a plurality of elevator cars are operated periodically in a circulating manner, similar to a bucket elevator (Paternoster). Unlike conventional bucket elevators, each cabin is driven independently of the other cabins and can therefore be parked independently of the other cabins at any desired parking station. A switching device is provided to switch the car from a vertical direction of travel to a horizontal direction of travel to enable movement of the car between different elevator shafts. Thus, the elevator car can move in a single plane, which plane is spanned by the two elevator shafts and the transverse shaft connecting the two elevator shafts.

In this case, the chain bucket elevator runs via a plurality of guide rails which are all oriented in one plane. This already requires early consideration in the design of the building and leaves only a small amount of leeway in the free, architectural design of future buildings.

The object of the invention is to further develop the elevator installation accordingly, and to enable greater flexibility in the design of buildings.

Patent application 102016211997.4, which has not yet been published, describes an elevator installation comprising a first guide rail oriented in a first direction, a second guide rail oriented in a second direction and a third guide rail oriented in a third direction. The elevator car can be transferred from one of the guide rails to another of the guide rails by means of a plurality of rotatable track sections. The guide rails are oriented in partially different planes.

Disclosure of Invention

The object of the invention is achieved by an elevator installation according to claim 1; preferred embodiments emerge from the dependent claims and the following description.

The elevator apparatus of the present invention comprises:

at least one first guide rail, which is oriented in a first, in particular vertical direction; at least one second guide rail, which is oriented in a second, in particular horizontal direction; at least one third guide rail, which is oriented in a third, in particular vertical, direction, and at least one fourth guide rail, which is oriented in a fourth, in particular horizontal, direction. Furthermore, the elevator installation comprises at least one elevator car which can be moved along the four guide rails.

A plurality of switching units is provided, wherein the elevator installation is provided such that the elevator car can be moved between the four guide rails by means of the switching units. The first and second directions define a first plane, and the third and fourth directions define a second plane. The first and second planes are angularly oriented with respect to each other.

The elevator installation according to the invention now achieves for the first time the operation of a bucket elevator forming a wall edge spanning a plurality of walls angled to one another. Thereby opening the possibility of architect design for future buildings. In modern measures, it is likewise possible to install modern bucket elevators which were not possible hitherto.

In one embodiment, the elevator installation comprises a first wall and a second wall, wherein the first plane is oriented parallel to the first wall and the second plane is oriented parallel to the second wall.

In one design, the first switching unit is arranged to transfer the elevator car from the first guide rail to the second guide rail, and/or the second switching unit is arranged to transfer the elevator car from the third guide rail to the fourth guide rail; and/or the third transfer unit is arranged to transfer the elevator car from the second guide rail onto the fourth guide rail.

In one embodiment, the plurality of switching units comprises a first rotatable track section which can be switched between an orientation in a first direction and an orientation in a second direction and/or a second rotatable track section which can be switched between an orientation in a third direction and an orientation in a fourth direction.

In one embodiment, the plurality of switching units comprises a rotatable third track section which can be switched between an orientation in the second direction and an orientation in the fourth direction. In particular, the rotatable third rail section is provided to overcome an angle between the first plane and the second plane. The rotatable third track section thus switches the elevator car from the first plane into the second plane. In this case, the axis of rotation is oriented in particular toward an edge at which the walls and/or planes meet or intersect.

In one embodiment, the rotatable track section is arranged rotatably about a third axis of rotation. The third switching unit is here designed such that, for the purpose of transferring the elevator car between the second guide rail and the fourth guide rail, the axis of rotation is transferred from the first position to the second position. In addition to the rotational movement of the track section, the track section is also moved laterally here. This is particularly advantageous for achieving a transition along the inner edge of the walls.

In one embodiment, the switching unit has a rigid and curved track section thereon, which forms a track connection between the second and fourth rails. In contrast to the rotatable track section, a permanent connection can now be provided here.

In one embodiment, the second direction may be oriented orthogonal to the first direction, and/or the third direction may be oriented orthogonal to the fourth direction.

In one embodiment, the elevator cabin backpack is guided in a supporting manner on guide rails.

In one embodiment, the first switching unit can be rotated about a first rotational axis which is perpendicular to a first plane spanned by the first and second guide rails and/or

The second switching unit is rotatable about a second axis of rotation that is perpendicular to a second plane spanned by the third and fourth guide rails.

In one embodiment, at least one of the converter units, in particular each of the three converter units, comprises at least one stator unit of the magnetic linear motor, which stator unit is provided for driving the elevator cabin, wherein the elevator cabin has a rotor unit, which interacts with the stator unit. The stator unit can in particular be rotated together with the rotatable track section.

All of the directions are oriented in different directions. In particular the first direction and the third direction are oriented parallel to each other. Within the scope of the invention, therefore, the parallel directions are to be regarded as different from one another, as long as they are not arranged superimposed on one another.

In one embodiment, the first and/or third direction is oriented vertically.

In one embodiment, the second and/or fourth direction is/are each oriented horizontally.

In one embodiment, "vertical" or "horizontal" is understood to mean "exactly vertical" or "exactly horizontal", respectively.

In particular, the guide rail is formed at least in the region of the rotatable track section in a straight line, in particular at least 2 meters from the rotatable track section.

When, in the context of the present invention, it is stated that the transfer from one guide rail to the other guide rail takes place via a rotatable rail section, this basically also includes the transfer in the opposite direction.

Detailed Description

Fig. 1 to 3 show a first embodiment of an elevator installation 1 according to the invention in different operating states. The following basic embodiments are also applicable to all other embodiments of the invention.

The elevator installation 1 comprises a first guide rail 10 along which the elevator car 2 is guided by means of a backpack support. The first guide rail 10 is vertically oriented in the z1 direction (first direction) and enables the elevator car 2 to be moved between different floors.

The elevator installation 1 comprises a second guide rail 20 along which the elevator car 2 is guided by means of a backpack support. The second rail 20 is horizontally oriented in the y2 direction (second direction).

The elevator installation 1 comprises a third guide rail 30 along which the elevator car 2 is guided by means of a backpack support. The third guide rail 30 is vertically oriented in the z3 direction (third direction) and enables the elevator car 2 to be moved between different floors.

The elevator installation 1 comprises a fourth guide rail 40 along which the elevator car 2 is guided by means of a backpack support. The fourth guide rail 40 is horizontally oriented in the x4 direction (fourth direction).

The second and fourth guide rails 20, 40 enable the elevator car 2 to be transferred from the vertical first guide rail 10 to the vertical third guide rail, in particular for providing modern Pater-nouster operation.

The elevator car 2 can be transferred from the first guide rail 10 to the second guide rail 20 by means of a first transfer unit 11, here in the form of a rotatable first track section 11. The rotatable first track section 11 can be rotated about a first axis of rotation a1, which is perpendicular to the first plane (yz-plane). The first plane is developed by the first rail 10 and the second rail 20.

The elevator car 2 can be transferred from the second guide rail 20 to the third guide rail 30 by means of a second transfer unit 22, here in the form of a rotatable second track section 22. The rotatable second track section 22 is rotatable about a second axis of rotation a2, which is perpendicular to a second plane (xz-plane). The second plane is developed by the third rail 30 and the fourth rail 40.

The guide rails 10, 20, 30, 40 are fixed to the first and second walls W1, W2. The first plane yz is oriented parallel to the first wall W1 and the second plane xz is oriented parallel to the second wall 2. The building environment defines the arrangement of the tracks.

The elevator installation 1 also comprises a third switching unit 33, four different embodiments being described below for this application. All third transfer units 33 are arranged to transfer the elevator car 2 from the second guide rail 20 onto the fourth guide rail 40 while overcoming the difference in angle X between the first plane and the second plane.

In the design of fig. 1, the walls W1, W2 enclose an angle X of 270 ° as seen from the elevator hoistway (fig. 1). The two walls W1, W2 intersect here at the outer edge K. For understanding the angle X, fig. 8 is referred to.

Fig. 8b shows a design similar to fig. 1, in which walls W and W2 meet at outer edge K. The angle X between the walls W1, W2 is greater than 180 °, in particular 270 °.

Fig. 8c shows an alternative within the scope of the invention, in which the walls W1 and W2 intersect at the inner edge K. The angle X between the walls W1, W2 is less than 180 °, in particular 90 °.

Fig. 8a shows a design in which two walls meet at an angle of 180 deg. for comparison purposes only. The two walls W1, W2 are not in this case oriented at an angle to each other.

The term "edge K" is to be understood in a broad sense and denotes in a broad sense the intersection of the two walls W1, W2. Including sharp edges K as shown in fig. 1-4, as well as flattened edges (fig. 5, 7) and rounded edges (fig. 6).

The features of each design are described below.

The elevator installation of the first embodiment (fig. 1 to 4) comprises a rotatable third track section 33A as a third transfer unit. Rotatable third track section 33A is rotatable about a third axis of rotation a3 oriented parallel to edge K. The third axis of rotation a3 also lies on the bisector 3 of the two walls W1, W2; the bisector 3 is an angular bisector of both the first plane yz and the second plane xz. The rotatable third track section can be pivoted between an orientation in the second direction (the elevator car can now be moved from the second guide rail 20 onto the rotatable third track section 33A and vice versa) and an orientation in the fourth direction (shown in fig. 1, shown in dashed lines in fig. 4) (the elevator car 2 can now be moved from the fourth guide rail 40 onto the rotatable third track section 33A and vice versa). In this embodiment, it is advantageous if the third axis of rotation a3 retains its position during the switching process.

The elevator installation of the second embodiment (fig. 5) comprises a rotatable third track section 33B as a third transfer unit. The rotatable third track section 33B can be pivoted by means of the pivoting mechanism between an orientation in the second direction (the elevator car can now be moved from the second guide rail 20 onto the rotatable third track section 33A and vice versa) and an orientation in the fourth direction (shown in dashed lines in fig. 5) (the elevator car 2 can now be moved from the fourth guide rail 40 onto the rotatable third track section 33A and vice versa).

The pivoting mechanism comprises a pivot arm 332, which is mounted in an articulated manner, so that the rail 331 of the rotatable rail section 33B can be pivoted in the region of the inner edge K. The pivoting mechanism may be considered as an integral part of the conversion unit. In addition to the pure rotational movement about the rotational axis A3, a change in position of the rotational axis A3 also takes place here. Fig. 5 shows that the axis of rotation a3 is once in a first position (solid line) in which the rotatable track section 33B is oriented in the second direction y2, and once in a second position (dashed line) in which the rotatable track section 33B is oriented in the fourth direction x 4.

The elevator installation of the third design (fig. 6) and the fourth design (fig. 7) comprises a

stationary track section

33C, 33D, respectively, as a third switching unit, which connects the second guide rail 20 and the fourth guide rail 40 to one another, in particular permanently. No rotation is now required.

The switching units are respectively provided with stator units 4 of a magnetic linear motor. In this context, configured means: stator unit 3 associated with a

rotatable track section

33A, 33B or a

stationary track section

33C, 33D₂₃At least temporarily, can be and are arranged for driving the elevator car located at/on the conversion unit. In particular, the stator unit can be considered as a component of the converter unit. The stator units are only schematically shown in some positions in the figures. Furthermore, the conversion unit may need to be provided with an auxiliary drive, which is not a magnetic linear drive, by means of which the elevator car can be driven in the region of the conversion unit.
