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 shared shaft. Moreover, the elevator system comprises a plurality of shafts. With the help of a repositioning assembly, the cars can be transferred from a first shaft into a second shaft.
An elevator system of this kind is disclosed in principle in EP 3 318 526 A1. In this case, a repositioning assembly comprises a plurality of repositioning modules 162 which can be assembled according to the configuration of the elevator system. Each module of this kind comprises a rail (reference number 176 in
The problem addressed by the present invention is that of developing an elevator system of the kind referred to above.
The patent application PCT/EP2018/050265 published subsequently discloses a multi-car elevator system. A repositioning assembly is formed by a rotatable rail segment. The elevator system has an adjusting assembly for adjustment of the rotational axis.
The problem underlying the invention is solved by an elevator system and a method as claimed in the main claims. Embodiments result from the sub-claims and the description.
The advantage of the elevator system according to the invention is, in particular, that the repositioning assembly can be fitted with quite rough tolerances. The adjusting assembly can be used to adjust the fitted repositioning assembly in such a manner that the cars are arranged as accurately as possible in the respective target shaft during operation following the repositioning process. Deformations during operation can make it necessary for the orientation of the repositioning assembly to be readjusted in this case.
Unlike in the case of the elevator system in PCT/EP2018/050265, the car is not mounted in a rucksack-type manner during vertical travel.
In particular, the car comprises guide rollers which are attached to opposite sides of the car.
In particular, the repositioning assembly has no rotatable rail segments.
The advantages mentioned in relation to the device or the method and other possible embodiments can easily be applied to the method or the device.
The invention is explained in greater detail below with the help of the figures. In the figures
The elevator system 1 comprises multiple repositioning assemblies 60a, 60b. With the help of a repositioning assembly 60 of this kind, a car can be repositioned from one shaft into the other shaft.
A repositioning process of the car 53a from the first shaft 51a into the second shaft 51b with the help of the upper repositioning assembly 60a is looked at by way of example. For this purpose, the car 53a runs along the vertical guide rails 52a vertically into the repositioning assembly 60a. The car 53a is then located in the first repositioning position 64a. From this repositioning position 64a, the car 53 could, on the one hand, continue to travel on vertically into the next story along the vertical guide rails 52a. On the other hand, the car 53a can also be transferred into a second repositioning position 64b in which said car is then arranged in the second shaft 51b.
For this purpose, the repositioning assembly 60a has a repositioning frame 61 which is likewise located in the first repositioning position 64a. If both the repositioning frame 61 and the car 53a are located in the first repositioning position 64a, the repositioning frame 61 can receive the car 53a.
A rail portion 62 of the vertical guide rail 52 can be separated from the remainder of the guide rail 52 in this case and fixedly connected to the repositioning frame 61. By being introduced into the first repositioning position 64a, the car 53a then reaches the guiding region of the rail portion 62. If the repositioning frame 61 then moves horizontally, this rail portion 62 is moved along with the car 53 guided on the rail portion 62 together with the repositioning frame 61. The repositioning frame 61 is then moved from the first repositioning position 64a into the second repositioning position 64b along a repositioning track 63. The repositioning track 63 may be a horizontal rail on which the repositioning frame 61 is guided. This repositioning principle is basically described in EP 3 318 526 A1.
An adjusting rail 73 is held on the adjustment base 71 such as to be displaceable in the y-direction. An adjusting slide 74 is held on the adjusting rail 13 such as to be displaceable in the x-direction. An adjusting screw 75 is fitted to the adjusting slide 74 from above. The adjusting screw 75 is guided through a threaded bore in the adjusting support 72. The directions of the individual adjusting means need not necessarily correlate with the spatial directions x, y, z.
As shown at the connection between the adjusting rail 73 and the adjusting slide 74, displaceability can be achieved by means of a dovetail guide. There is also a dovetail guide of this kind between the adjustment base 71 and the adjusting rail 73, but it cannot be seen in this representation. By turning the adjusting screw 75, the adjusting support 72 can be raised or lowered in the z-direction in relation to the adjusting slide 74. The adjusted relative position of the adjusting support 72 in relation to the adjustment base 71 is fixed following adjustment.
Alternatively, the repositioning assembly may also comprise a conveyor belt assembly 60b, as illustrated in
It is not necessary for rail portions 62 to be repositioned with the car 53 in the conveyor belt embodiment. Otherwise, the method of operation is identical to the previously described embodiment with the repositioning frame.
The adjustment can be carried out once during commissioning. There is no need for continuous adjustment during routine operation. Checks that the orientation is correct can be made during routine maintenance work.
