Description

elevator system

The invention relates to an elevator system.

The invention is applicable to elevator systems in which a plurality of cars can travel simultaneously in a common shaft. In addition, the elevator system comprises a plurality of shafts. Using a transfer arrangement, the cabins can be transferred from a first shaft to a second shaft.

Such an elevator installation is basically disclosed in EP 3 318 526 A1. A

Conversion arrangement here comprises a multiplicity of conversion modules 162 which, depending on

Configuration of the elevator system can be put together. Each such module comprises a rail (reference number 176 in FIG. 3), which together form a transfer track. A cabin guide (reference number 172 in FIG. 3) represents a transfer carrier which transfers the cabin from a first transfer position in a first shaft to a second transfer position in a second shaft along the rail. These modules are placed on a floor using a frame (reference number 170 in FIG. 3). However, this modular arrangement is quite limited in its variability. In addition, the frames must be placed very precisely during assembly.

It is an object of the present invention an elevator system mentioned at the beginning

further.

The post-published patent application PCT / EP2018 / 050265 discloses a multi-cabin elevator system. A transfer arrangement is formed by a rotatable rail segment. The elevator system has an adjusting arrangement for adjusting the axis of rotation.

The object on which the invention is based is achieved by an elevator installation and a method according to the main claims. Embodiments result from the subclaims and the description.

The advantage of the elevator installation according to the invention now lies in particular in the fact that the installation of the transfer arrangement can take place with very rough tolerances. On the basis of the setting arrangement, the assembled transfer arrangement can be set in such a way that the cabins are arranged as precisely as possible in the respective target shaft after the transfer operation. Deformations during operation may make it necessary to readjust the orientation of the transfer arrangement. In contrast to the elevator system of the PCT / EP2018 / 050265, the cabin is open during the

Vertical travel not stored in a backpack.

In particular, the cabin includes guide rollers attached to opposite sides of the cabin.

In particular, the transfer arrangement has no rotatable rail segments.

The advantages mentioned with regard to the device or the method and others

Design options can be readily applied to the method or the device.

The invention is explained in more detail below with reference to the figures. Each show

Fig. 6 schematic the cabin and the vertical guide rails from above.

FIG. 1 shows parts of an elevator installation 1 according to the invention. The elevator installation 1 comprises fixed guide rails 52, along which cars 53 can be guided in the vertical direction. First vertical guide rails 52a are arranged in a first shaft 51a and second guide rails 52b are arranged in a second shaft 51b. The elevator installation comprises a plurality of cars 53a, 53b, 53c, 53d, wherein in particular more than two cars can move simultaneously in one shaft.

The elevator installation 1 comprises several transfer arrangements 60a, 60b. With the aid of such a transfer arrangement 60, a cabin can be transferred from one shaft to the other. A transfer process of the cabin 53a from the first shaft 51a to the second shaft 51b is considered by way of example using the upper transfer arrangement 60a. For this purpose, the cabin 53a moves vertically into the transfer arrangement 60a along the vertical guide rails 52a. The cabin 53a is now in the first transfer position 64a. From this

Relocation position 64a, on the one hand, the car 53 could continue vertically to the next floor along the vertical guide rails 52a. On the other hand, the cabin 53a can also be transferred to a second transfer position 64b, in which the cabin is then arranged in the second shaft 51b.

For this purpose, the transfer arrangement 60a has a transfer frame 61 as a transfer carrier, which is also located in the first transfer position 64a. When both the transfer frame 61 and the cabin 53a are in the first transfer position 64a, the transfer frame 61 can accommodate the cabin 53a.

One rail section 62 of the vertical guide rail 52 is different from the rest

Guide rail 52 separable and firmly connected to the transfer frame 61. By the

Moving into the first transfer position 64a, the cabin 53a now reaches the guide area of the rail section 62. If the transfer frame 61 is now moved horizontally, this rail section 62 moves together with the cabin 53 guided on the rail section 62 together with the transfer frame 61. The transfer frame 61 is now shifted from the first transfer position 64a to the second transfer position 64b along a transfer track 63

Transfer track 63 can be a horizontal rail on which the transfer frame 61 is guided. This implementation principle is basically described in EP 3 318 526 A1.

FIG. 3 shows an exemplary setting device 70 in a possible embodiment. The adjustment device 70 comprises an adjustment base 71, which in a predetermined position e.g. can be attached to the shaft wall 54. A setting bracket 72 is attached to the transfer track 63 in a predetermined position. The setting bracket 72 can also be an integral part of the transfer track 63. The relative position of the setting bracket 16 relative to the respective setting base 12 defines the position of the transfer track at least locally.

An adjustment rail 73 is held on the adjustment base 71 so as to be displaceable in the y direction. An adjusting slide 74 is held on the adjusting rail 13 so as to be displaceable in a direction x. An adjusting screw 75 is placed on the adjusting slide 74 from above. The adjusting screw 75 is guided through a threaded hole in the setting bracket 72. The directions of each

Setting means do not necessarily have to correlate with the spatial directions x, y, z. The displaceability can, as shown on the connection between the adjustment rail 73 and the adjustment slide 74, be realized by a dovetail guide. Such a dovetail guide is also present between the adjustment base 71 and the adjustment rail 73, but is not visible in this illustration. By turning the adjusting screw 75, the setting bracket 72 can be raised or lowered in the z direction relative to the adjusting slide 74. The set relative position of the setting support 72 relative to the setting base 71 is fixed after the setting.

Alternatively, the transfer arrangement can also comprise a conveyor belt arrangement 60b, as illustrated in FIG. 5. Such an arrangement can be used in particular on a lower conversion arrangement. Conveyor belt arrangement 60b comprises a conveyor belt 66, the car 52d to be relocated being placed on this conveyor belt. The area of the conveyor belt on which the cabin is mounted is regarded as a transfer support 61.

The conveyor belt 66 and thus the transfer carrier 61 are guided on the basis of bearing rollers 67. The transfer track 63 is determined by the arrangement and alignment of the bearing rollers. The bearing rollers are aligned by the setting arrangement 7, analogously to the previous one

Design. The transfer positions 64a, 64b are thus set.

It is not necessary for rail sections 62 to be moved with the cabin 53 when the conveyor belt is designed. Otherwise, the mode of operation is identical to the configuration described above with the transfer frame.

The setting can be carried out once during commissioning. Continuous adjustment is not necessary during operation. To regular

The correct alignment can be checked for maintenance work.

As FIG. 2 shows, the transfer carrier is guided on the transfer track 63 by means of a roller guide 65. The transfer track can in this case be formed by a horizontal rail, such a rail also being able to be present on the other side. The transfer track 63 is held on the shaft wall 54 via a plurality of setting devices 70 (see also FIG. 4).

A setting process is illustrated in FIG. 2 using the first conversion arrangement 60a. FIG. 2a shows the transfer carrier in 61 together with the cabin 53a in the second, not yet aligned transfer position 64b. It can be seen that the rail section 62, which together with the cabin 53a has been moved from the first transfer position to the second transfer position, is not aligned with the vertical guide rail 52b in the second shaft. There is a change in the position of the conversion track 63 in the setting device 70b Area of the second transfer position 64b first in the z direction (FIG. 2b) and then in the x direction. The rail section 62 is then aligned, at least in a side view, with the vertical guide rail 52 in the second transfer position 64b. Alignment in the position in the X direction can be carried out using a stop (not shown), which can also be part of the setting arrangement. The travel path of the transfer support 61 along the track 63 can be limited in a defined manner by the stop. Now the cabin 53 can now move vertically in the second shaft.

Figure 7 shows the storage of the cabin during vertical travel. The cabin is guided on the at least two vertical guide rails by means of guide rollers. The at least two vertical guide rails are arranged on opposite sides of the cabin.
