Chain conveyor for fully mechanical extraction

The invention relates to a chain scraper conveyor which, in a known manner, also serves as a guide rail for a coal plow and / or with cutting machines or the like additionally guided above the conveyor on the upper profiles of the conveyor. Such conveyors have a U-shaped hood on the mountain face side, which is connected with its free legs pointing towards the middle of the channel with the mountain face side profile and two guide channels each for the endless one. Forms the pull chain of the coal plow, the sword end of a coal plow also being guided in the lower chain guide channel. In such conveyors it is also known, the conveyor side profile söge on both sides of the conveyor to provide "called support plates through which the entire conveyor is lifted and now rests on these support plates and no longer on the bottom profile of the conveyor on the footwall ₀ The thus obtained free Space is used, for example, to accommodate so-called holding chains for conveyors in steep storage and creates the possibility of driving raised scratches upright through the lower run (German utility model 1 872 409).

It is also known to have a cutting machine and a coal * Guide the planer on a conveyor at the same time (German patent specification 803 109) o This does not lead to any noteworthy

Difficulties when using a conventional type of coal plane guided on a guide rail kohlenoßsei tig finds ο If, however, a coal plane is used, which is butt side is guided within the hood covering the aforementioned chain guide, it must be prevented that the coal plow located on the coal face side can perform all vertical movements in relation to the conveyor, or Conversely, the conveyor versus the coal plow »For this purpose it is known to design the coal plow in such a way that it is provided with a protruding nose over the side profile of the conveyor, with the help of which conveyor and coal plow always

en
are held together, "This nose or differently designed parts of the coal plow that cross the conveyor are now like" which is annoying because whenever the chipping machine and the coal plane meet, the cutting machine is guided with its skids on the upper profile of the conveyor "

Beyond these difficulties, those on the upper parts of the coal plow that are guided by the flange of the conveyor cause considerable wear and tear on the upper profile, which must be countered » As is well known, conveyor troughs cannot simply be used again when their upper profile is worn out she flips it over because the lower profile is dimensioned differently, as the bottom ends are also bent at one end in order to be able to cope with to overlap the adjacent floor pan of the next channel.

To counter the wear and tear on the upper profiles and a Possibility of attaching brackets, add-on parts or the like to the conveyor side profile by means of hook bolts or To enable such a thing, it has already been suggested after older proposals that do not belong to the state of the art, to attach strips to the upper and / or lower profiles, These strips can then be used on the coal face side as wear parts for the parts of the coal plow that extend into the conveyor serve. But once such a strip is worn out

so there is inevitably the requirement to expand the entire channel and create it above ground in order to weld on a new strip. Naturally, a solution in which the repair of the channel could be carried out underground would be more advantageous. The invention is therefore based on the object, the conveyor to be redesigned so that on the one hand the cutting machine and conveyor can pass each other unimpeded and on the other hand an easy interchangeability of the guideways, which are particularly exposed to wear, is made possible.

The invention solves the problem in that a hood forming a guide rail is also provided on the coal face, the hood consisting of a U-shaped and a flat sheet and the free legs of the misshapen sheet welded to the flat sheet to form a box girder and the hood is attached to the conveyor side profile in such a way that the flat sheet serves as a bracket. The given task is fulfilled by the solution. While the cutting machine is on. is guided by the remaining free part of the upper flange of the conveyor, the planer is guided by the respective upper flange of the attached hood. Both can now pass each other unhindered. Furthermore, there is the possibility of simply turning the hood by 180 °. According to a further feature of the invention, the hood is designed ₃ so that the hoods corresponding in cross section to a wide U have reinforcing ribs on the inside, between which at the fastening points through Recesses in the outer plank surface accessible, the holes having plates are arranged. In this case, the hoods are fastened to the conveyor side profile advantageously below or above the central longitudinal plane of the hoods. According to a further feature of the invention, the Haie is designed so that the fastening points are provided at the ends of the sections forming the conveyor and the recesses are dimensioned so large that the connecting devices holding the sections together are accessible from the outside
