At least one drive module with driving pulleys that can be combined with the head module or base module is connected through support organs to the cabin. The drive module is designed as a supporting part of a drive-head module or a drive-base module. It has a motor with two drive shafts, each with a driving pulley.

Description

The present invention relates to a prefabricable, modular elevator for the transportation of people and / or Goods, which has a wall with shaft doors Building is connectable and essentially from one Foundation module, a head module, columnar guide modules and an elevator car, and preferably counterweights has, which are guided in the management modules.

Because of the performance and variability this is Elevator type suitable for both small and tall buildings. The area of application ranges from small goods lifts to Bed lifts for hospitals or the like.

With the as yet unpublished EP application No. 96108133.8 an add-on elevator of the type mentioned above, the Cabin arranged by means of a below the cabin Friction wheel drive as a vertically self-propelled transport unit is trained.

The advantage of self-driving cabins is that none Machine room is needed and that several cabins in the same Shaft can run. On the other hand, the drive must be permanent be carried along.

Here, the invention now wants to operate an elevator car show a solution that also has no machine room is required and in which the drive unit with the Elevator car does not need to be carried. The remains Modular structure obtained, which is the factory production of complete elevator systems with different capacities and allowed for different building heights.

The invention is characterized in claim 1 and stands out i.a. characterized in that a stationary drive as part of the Module system is designed and as such a drive head module or forms a drive foundation module.

Advantageous further developments and improvements are in the Subclaims listed.

The drive module is a supporting part of a drive head module or a drive foundation module.

The one designed as a drive head module or drive foundation module Stationary drive has two drive shafts, each with one Traction sheave on.

The outgoing drive shafts run in a protective tube and are stored again at its outer end, the Protective tube end without additional elements, parts in an opening of the management module is supported.

An arrangement of the traction sheaves immediately above the Guide modules save any additional pulleys.

A slim, elongated drive requires only a small amount Overall height, so that if the elevator is in one existing shaft is installed, this shaft does not have to be extended upwards due to the drive.

The stationary drive can, for example for a Performance doubling, divided into two individual drives, each of the two drives assigned to a guide module will be formed and double drive head or foundation modules can.

A drive head module or a drive foundation module is included Guide modules, mounting modules and a head or Foundation module can be assembled into a self-supporting frame, which is a unit that can be transported by truck or train forms.

By an opposite arrangement of the Individual drives on the head module become one around the transverse axis balanced load on the head module reached.

In FIG. 1, 1 denotes a building wall on which guided by two columnar guide modules 10, one Elevator car 5 moves up and down. A shaft as a structural one Part of a building and as a carrier of Fastening fittings for guide rails of the cabin and the Counterweight and other elevator-specific devices is not absolutely necessary. The guide modules 10 extend themselves over several floors 8 and are provided because of the Road transport a maximum of about 18 m long. By joining them together Several elements can easily move up to higher buildings 100 m and more can be executed with it.

The elevator car 5 has guide rollers 17 on an upper yoke 4 and on a lower yoke 7, and a rope end attachment 20 on upper yoke 4. The upper yoke 4 and the lower yoke 7 are vertically connected to the catch frame 6. The guide modules 10 are by means of mounting modules 11 on the floors 8 with the Connected building. The guide modules 10 are below with a Foundation module 13 cross-connected and on the shaft floor switched off. The foundation module 13 also carries one or two Buffers 23. Above are the guide modules 10 with a head module 2 cross-connected, here the head module 2 a drive module 12 carries and in this combination as a drive head module 22nd referred to as. The drive module 12 has lateral Traction sheaves 14, over which three suspension cables are looped, those with the elevator car 5 and with those in the guide modules 10 running counterweights 9 over the second rope end fastenings 20 are connected. Of the two traction sheaves 14 is in the View of Fig.1 only one of them visible. The same applies the guide modules 10 and the counterweights 9. The guide modules 10 can be designed as any profile, with or without guides for a counterweight.

In Fig.2 the modular elevator is in one Elevator shaft 27 arranged. Seen from above, there are more Details of the drive head module 22 can be seen. This exists from a central between two parallel cross beams arranged drive module 12 with a motor 19. This has outgoing drive shafts 18 on both sides, on which at the outer ends each have a traction sheave 14 attached. The Drive shafts 18 are what is not in the schematic illustration can be seen, provided with a protective tube, the Protective tube at the outer end behind the traction sheave 14 Has shaft bearings. This is to support this bearing Protective tube at this outer end in a corresponding Guided recess in the guide module 10, so the vertical force the attached load with the elevator car 5 and the Counterweight 9 in the kink-resistant guide module 10 is directed. With this arrangement there are no bending forces in the drive shafts 18. The drive module 12 is as supporting part of the drive head module 22 and replaces further stiffening connecting struts between the Cross beams.

The drive module 12 does not include a motor 19 brake shown and in some cases also not shown reduction gear. The drive module 12 is advantageously constructed as in EP 96107861.5, which for Part of this application is declared, i.e. with a hollow Rotor shaft formed, resulting in a slim, elongated Design with a small diameter of the drive leads. With that the additional use of small traction sheaves 14 from 150 to 300 mm diameter and preferably aramid ropes only very little horizontal height required. The outgoing suspension cables 3 the Traction sheaves 14 lead to the center practically without an oblique pull of the guide modules 10 to the counterweights 9 on one side and to the rope end fastenings 20 on the side arm of the Frame 6 of the elevator car 5.

3 and 4 show in principle the same arrangement of the Drive module 12 as in the previous dispositions. Of the The difference to these is, however, that here the Elevator car 5 and counterweights 9 are suspended 2: 1. For this purpose, 5 pulleys 15 and on the elevator car Counterweights 9 pulleys 16 available. Furthermore are the rope end fastenings 20 on the drive head module 22. With this In many cases the disposition can be reduced to a reduction gear Drive module 12 can be dispensed with, at lower costs even better efficiency is achieved. This Disposition is intended for those use cases where larger Transport loads at low to medium speeds are.

The disposition according to FIGS. 5 and 6 show another one Possibility of how the performance range of the invention Elevator system can be expanded even more upwards. For this the drive modules 12 are used twice, one each the left and the right guide module 10 suitable boom construction, not shown in detail, the two drive modules 12 are fixed with the head module 2 connected and thus form a double drive head module 24. In the shown are the elevator car 5 and the Counterweights 9 also hung in a ratio of 2: 1, which, at halved speed, the logical doubling of the Load capacity results. In the illustration shown, the two are Drive modules 12 arranged opposite to each other. This aims to equalize the load torque around the transverse axis at Head module 2 or double drive head module 24. When in use of the drive module 12 for a double drive has the motor 19 only one outgoing shaft 18 with a traction sheave 14.

7 and 8 show a disposition as the last variant underlying drive. Here, the drive module 12 with the Foundation module 13 firmly connected and the suspension cables 3 are over Deflection rollers 15 and 16 on the head module 2 to the elevator car 5 and the counterweights 9, with 15 as a pulley for the Elevator car 5 and 16 as a deflection roller for the counterweights 9 is provided. The deflection rollers 15 and 16 are by means of a Fastening bracket 21 each attached to a guide module 10. The Foundation module 13 is thus shown for drive foundation module 25 will be a 1: 1 suspension for the elevator car 5 and Counterweights 9. However, it is also with an underlying drive possible to implement a 2: 1 suspension. Likewise, a Doubling the drive power can be achieved by, as in overhead drive, two drive modules 12 are provided and so a double drive foundation module 26, not shown form.

The examples shown show the customization options for a Modular systems to a wide range of needs in terms of conveyor load and speed. A large part of the same modules can be used here can be used for all disposition variants. The Performance adjustments in terms of load capacity and speed can by the number of drive modules 12, with and without Reduction gear, as well as combined with the suspension type 1: 1 or 2: 1 can be varied. When using motors 19 with different performance are in terms of load capacity and Speed opened up even larger areas of application.

In the case of double drives, a corresponding motor control for example with the same speed and torque setpoints, ensures that the same tensile forces on both sides to rule. As an inevitable synchronization of the two drives can with suitable means, for example with chain and Sprockets, mechanical coupling can also be provided.

The slim, elongated shape of the drive head module 22 or Drive foundation module 25 makes it possible to guide modules 10 with very short mounting modules 11 very close to the building to arrange, then the horizontal forces occurring from the Building structure to be included. So that is the present Modular system also for the realization of backpack elevators suitable.

Installation of the elevator according to the invention in a shaft 27 does not change the modular disposition. Existing Shaft walls then only serve as a barrier and are not included Fastening fittings loaded. The elevator can be considered complete prefabricated unit can be introduced from above into the still lowered shaft 27 and then on the shaft door wall be attached.
