DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The object of the present invention is a storage structure, particularly a car park, with a large number of storage areas, particularly vehicle parking places, arranged helically around a cylindrical shaft, and with a lifting vehicle operated in a helical fashion in the shaft around the vertical axis, the lifting vehicle being fitted with at least one consumer, in particular an electrical consumer, which needs to be supplied.
Such a storage structure, designed as a car park, is known, for example, from the German patent publication of the unexamined application No. 1684721. In this document, the lifting vehicle is designed as a platform which takes an automobile, which is advanced by gearing onto a track which runs helically around the shaft. A vehicle, parked in a drive in box, is mechanically conveyed to the platform and is then helically raised until it is opposite an empty parking place. The automobile is mechanically parked in the parking place. Conversely, the parked automobiles can be moved in the opposite sequence from the parking places to the platform, and then by means of the platform to a drive-out box.
The platform is fitted with electric motors to drive it. Additionally, the loading device, by means of which a vehicle is conveyed on to and off the platform, also has an electromotive drive.
SUMMARY OF THE INVENTION
DE-OS 1684721, contains no description of how the electric motors fitted to the platform are to be supplied with electricity.
The object to be achieved by the present invention is to provide, in design, a generic storage facility, an economical, reliable, low-maintenance solution for the connection to a supply unit of the consumers which are to be fitted to the lifting vehicle.
In accordance with the present invention, this object is achieved, as a first alternative, by means of the characteristics of claim 1. An alternative solution to the object is indicated in claim 2.
Cavities for the laying of a supply line are known from the prior art (e.g. DE-GM 9012229 1, U.S. Pat. No. 3,300,154, FR-B-1304183, and GB-B-1213037).
The invention is described below in further detail on the basis of the first alternative solution indicated in claim 1. The advantages indicated below also apply to the second alternative solution.
The invention is obviously applicable to all kinds of supply lines. i.e. electrical, hydraulic and pneumatic lines, as well as water and gas lines, and also to data transmission and other control lines. Wherever references are made below to electrical supply lines, this indicates an illustrative application which does not restrict the invention.
The invention is such as to avoid the use of sliding contacts, which are otherwise normally used--for example, in the case of parts which are electrically connected to each other and rotate around each other. Rather, the supply line is designed so that it is firmly connected to the lifting vehicle at one end, and to the structure at the other end. This ensures that, in the case of an electrical supply line, supply achieves a high degree of reliability not possible in the case of rubbing contacts. By designing the open-top cavity that accommodates the supply line so that its external circumference basically corresponds to the pitch of the helix for the lifting vehicle, it is possible to achieve a completely twist-free laying of the supply line. In this way, the supply line attains a practically unlimited lifespan. The minimal stress on the supply line is also reflected in increased supply reliability. Because the cavity in which the supply line is laid is arranged around the vertical axis of the shaft, it is possible for the supply line to move freely without rubbing against the walls of the cavity. This also contributes to the mechanical protection of the supply line and to an increase in its lifespan.
Assuming that the external circumference of the cavity in which the supply line is to be stowed should "largely" correspond to the pitch of the helix for the lifting vehicle, it may be deduced that--de
