DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a belt conveyor plant for conveying bulk material in open air and in particular hilly terrain between two terminal stations for the loading and offloading respectively of the bulk material.
BACKGROUND OF THE INVENTION
Conventional conveyor belt plants of this kind operate with a flat conveyor belt whereof the load section has a trough shape imposed on it to increase the conveying capacity. A continuous supporting framework extends between the two terminal stations, on which are situated carrier roller stations for guiding and supporting the load section and also the return section of the conveyor belt. The carrier roller stations for the load section impart the trough shape to the same. So that the trough shape is not lost between two consecutive carrier roller stations, their maximum mutual spacing is limited to comparatively small values, e.g. of 1 to 2 m and at most 4 m. The supporting framework and the carrier roller stations positioned at comparatively close intervals represent a considerable structural complexity. The application of a belt conveyor plant of the kind described is frequently impossible or possible only on a costly artificial grade in difficult and in particular hilly terrain, because of the need to have the supporting framework between the two end stations.
OBJECT AND SUMMARY OF THE INVENTION
The invention is based on the task of devising a belt conveyor plant for bulk or loose material for which a comparatively low degree of structural complexity is sufficient whilst being applicable equally well on optional terrain and in particular also hilly and difficult terrain without difficulty, whilst overcoming differences in altitude.
A belt conveyor plant which resolves this problem is characterised in accordance with the invention by the following features:
an endless conveyor belt of rubber or the like is provided, comprising a transversely stable belt member and two lateral undulant lateral sides, being so-called corrugated borders;
the two sections or legs of the conveyor belt run between the two end stations over a number of mutually spaced apart carrying and locating or guiding systems in each case, which are carried in each case by a bearer anchored separately in the soil or subsoil;
the conveyor belt sags freely between the carrying and locating systems;
the mutual spacing of the individual carrying and locating systems is dimensioned for a relative sag of at least 2% of the load section of the conveyor belt;
each carrying and locating system comprises devices for straight lateral guiding of the conveyor belt;
the carrying and locating systems allocated to the load leg are designed for belt guiding in flat non-concave form.
The belt conveyor plant according to the invention operates in accordance with the principle of a cableway. The conveyor belt is no longer supported and guided in practically continuous manner by means of a closely set succession of carrier roller stationsbut only on individual bearers positioned at operatively great mutual distances, which are anchored on or in the soil via an appropriate foundation in each case, separately that is to say without a mutual structural connection. A continuous support framework is eliminated thereby. The forming into trough shape of the conveyor belt or rather of its load section is also renounced. To secure adequate conveying capacity, the flatly guided conveyor belt is provided with two lateral corrugated sidewalls which endow the conveyor belt with a large box-shaped cross-section, in a manner known per se. This eliminates the beating effect placing the durability of a conveyor belt at risk upon utilising rollers imposing a trough shape, as engendered if the roller spacings are chosen too great. The conveyor belt sagging freely between the bearers may be deflected in transverse direction in these sections, e.g. under the action of winds. That it nevertheless retains its trajectory as a whole is accomplished by the devices for straight lateral guiding of both legs of the conv
