DESCRIPTION:
BRIEF SUMMARY
This is a national phase application of PCT/EP 93/00318 filed 10 February 1993 and based, in turn, on a German application P 42 05557.1 filed 24 February 1992 under the International Convention.
FIELD OF THE INVENTION
The invention relates to a mobile connecting belt bridge for open pit mining comprising one end on the feed side for being fed by a mining or winning apparatus and a discharge end for transferring conveyed material onto a pit level belt.
BACKGROUND OF THE INVENTION
Known connecting belt bridges are--optionally by way of an intermediate belt bridge-fed with a material to be conveyed either by a substantially-stationary winning apparatus (e.g. a bucket wheel excavator) or a crusher plant. Such connecting belt bridges either convey on the same level or in the form of elevator conveyors onto a higher level (of e.g. DE-OS 36 23 813). The known connecting belt bridges are substantially stationary and are only moved onwards once the feeding apparatus or the feeding plant undergoes a change in locality.
Linearly moving a winning or mining apparatus comprising an excavating means excavating in the direction of travel (of e.g. U.S. Pat. No. 3,897,109) is known from DE-OS 39 11 119 and this machine deposits the material which is excavated on the pit level belt by a belt arrangement comprising a plurality of mobile belt units. However the operation of such a belt arrangement requires considerable monitoring effort.
From DE-OS 39 20 011 a band bridge is furthermore known cardanically linked to a linearily moving winning apparatus and which at its discharge end is likewise cardanically linked to a funnel wagon travelling on the travelling rails of the pit level belt and movable jointly with the winning apparatus and the funnel wagon. However, this known belt bridge is permanently coupled to the winning apparatus and the pit level belt and therefore severely restricted in respect of its dimensions, in particular, in relation to level differences between the winning or excavation plane and the plane of the pit level belt.
OBJECT OF THE INVENTION
Accordingly a need exists to so improve a connecting belt bridge of the type referred to in the introduction, that it is suitable to be fed by the discharge belt of an excavating or winning apparatus and is linearly movable.
It is therefore an object of the invention to provide a connecting belt bridge overcoming drawbacks of the known connecting belt bridges. Yet another object of the invention is to provide the connecting belt bridge fed by the excavating or winning apparatus linearly movable both in a high level cut mode (excavation above the level of the pit level belt) as well as in a low level cut mode (excavation below the plane of thee pit level belt).
SUMMARY OF THE INVENTION
The present invention provides an apparatus wherein both the feed end as well as the discharge end of the bridge are each supported on a separate travelling means, the discharge end travelling means is of portal-like design comprising at each of both sides of the pit level belt at least one non-railborne travelling unit (e.g. a chain drive), the bridge on the travelling means at the discharge end is pivotal both about a vertical axis as well as a horizontal axis and on the feed side the travelling means is supported by way of a longitudinally displaceable single point support with a support beam which is horizontally alignable and the bridge at its feed end comprises a feed jib linked about a horizontal transverse axis.
The two travelling means permit unimpeded manoeuvring of the connecting belt bridge during a locality change. This is substantially contributed to by the fact that the travelling means on the discharge side comprise travelling units which are not railborne. By virtue of the three-point support the connecting belt bridge is suitable both for the high level cut as well as the low level cut of the winning apparatus. The linkage connection of the feed jib permits, moreover, to always provide the winning apparatus which feeds the material with a favorable feeding
