The invention relates to an offset device an exploited and possibly looted pit space or for the packaging of Packed goods in a so-called old man.

It is often necessary that the old man be replenished with mountains or other garbage is used to support the overlying mountain layers, and various methods are used for this purpose applied, either manual offset or machine offset, with z. B. compressed air for Application or scraper devices are used.

The invention is based on the object of an improved mechanical device for bringing up and packaging of backfill goods.

To solve this, the invention uses a scraper chain conveyor, as it is known per se Way is used in mining. Such Kraizkette conveyor have a cover plate along the the good is promoted, the cover plate normally in a horizontal position or parallel to Is arranged lying of the mine construction in question, seen in both directions, d. H. transversely to the conveying direction of the conveyor and in the longitudinal direction of the conveyor. As a result, the level becomes the cover plate, which extends transversely to the conveying direction of the conveyor, here with the expression "Funding level" denotes, and where it is expressed that the funding level is "horizontal" runs, it should be meant that the conveying level is horizontal or parallel to the lying of the Mine construction lies.

The invention consists in a displacement device with a scraper chain conveyor, which one Training for receiving and guiding conveyor chains and conveyor elements connecting them wherein the conveyor has a conveyor plane which is horizontal over a first part of its length is arranged and extends over a second part of its length at an angle with respect to the first part, so that deposited on the first part of the conveyor backfill along the second part of the Conveyor is unloaded.

According to one embodiment of the invention, the conveyor is at each end of the aforesaid first Partly equipped with the aforementioned second part.

Another preferred embodiment of the invention consists in that the conveyor consists of a plurality of trough-shaped or trough-shaped sections is composed, which abut with their ends to form a continuous trough for the Mining offset device

To form conveyor chains and attached scraper elements. Said first and second parts of the conveyor can be connected to one another by at least one trough-shaped section of which Conveying plane runs at one end at an angle to its other end, between the Parts is turned on. If only a trough-shaped section is used to use the parts is, the conveying plane of this connecting section can be twisted at a right angle.

In operation, d. That is, if the displacement device is installed in the pit to dispose of material into a To spend old man or equivalent pit room, it is appropriate to use the first mentioned Part of the conveyor in the vicinity of an extraction point or other "source" of backfill material to arrange and the second part or the second parts in the old man himself or in his immediate neighborhood.

The invention is described below with reference to an exemplary embodiment which is shown in the drawing is illustrated, explained, namely shows

F i g. 1 the conveyor in a side view,

F i g. 2 the conveyor in cross section.

A conveyor designated as a whole with the number 1 is composed of trough-like sections, wherein the ends of the sections abut one another and each have a cover plate 2, which extends as a connection between two side pieces 3. The cover plate 2 and the Side pieces 3 of each section together result in the trough-like design and are designed to take up and guide endless conveyor chains and transverse elements arranged between them. the

Claims (1)

Chains and the cross members, e.g. B. scratch plates are not shown. The conveyor 1 is built on supports 4, and a plate 5 is arranged between one side of the conveyor and the horizontal. The conveyor is driven by a hydraulic or electric motor 6 which is located at one end of the conveyor. Although only one motor is shown in the drawing, one motor may be provided at each end of the conveyor. The conveyor 1 is shown in a position which is in the vicinity of a long-pile mineral front F, along which a pusher conveyor 7 is laid and removal rams 8 are set. A hydraulic lifting mechanism 10 is attached to an expansion support frame 9, the piston 11 of which is connected to the conveyor 1. The lifting mechanism 10 is provided to advance the conveyor 1 according to the progress of the dismantling. As can be seen from FIG. 1 results, the conveyor 1 extends in the transverse direction through a pit section R and is at each of its two ends adjacent to the exploited, z. B. charred and looted area G of the mining site. The section of the conveyor 1 crossing the pit section R is set horizontally with respect to the plane in which the conveyor is carried out. On each side of the route, the conveyor runs into the old man G, and in the process the conveyor twists increasingly at a right angle until it runs vertically within the old man with its conveyor plane. In operation, the conveyor is used as a device for transporting and moving backfill material in the old man of a long-haul mining site as follows: The material gained when driving into the mine section R falls or is loaded onto the part of the conveyor 1 that runs in the horizontal plane within the section cross-section The conveyor is then put into operation and transports the goods to one side of the route R and to the old man G. When the goods reach the part of the conveyor 1 which is arranged in the vertical plane, the conveyor moves it towards the old man dumped. In this way the good, e.g. B. Berge, in the old man G and is packed there to form a support for the hanging wall in the area of the old man. A rolling back of the backfill material in the direction of the working face F is prevented by the plates 5. When the backfill has initially been packed up to the hanging wall, excess small material is snapped in along the offset hole, which gradually creates a lengthened or even higher pack and at the same time the area near the leading edge of the offset is packed even more tightly. After the old man G is sufficiently offset on one side of the pit section R, the direction of movement of the conveyor is reversed, and the old man on the other side of the section R is filled with material and packed. Once the old man areas are on either side of the stretch? are offset, the advance of the conveyor 1 takes place by means of appropriate actuation of the hoists 10. Although it is shown in the drawing that the conveyor has two parts that extend from the pit section R to both sides into the old man, the Invention can also be used if there is an old man only on one side of the route. In that case, the conveyor would only have a portion that pulls off the route to the Old Man. Similarly, a modification is possible with regard to the angle by which the conveyor twists from the route towards the old man. A right angle is shown in the drawing, but it can also be a smaller angle, depending on the grain size of the backfill that is transported by the conveyor. The features of the subject of the application disclosed in the above description, in the drawing and in the following patent claims can be essential both individually and in any combination with one another for the implementation of the invention in its various embodiments. Patent claims: 1. Device for moving exploited mine spaces with a scraper chain conveyor, characterized in that the - defined in the description - funding level of the scraper chain conveyor (1) arranged horizontally over a first part of its length and is angled over a second part of its length in relation to the first part, so that the material loaded onto the first part of the conveyor along the second part of the sponsor is given by the latter. 2. Device according to spoke 1, characterized in that the first part of the conveyor (1) is provided with a second part at each of its ends. 3. Apparatus according to claim 1 or 2, characterized in that the scraper chain conveyor consists of a plurality of trough-like sections (1,2,3) with their ends are arranged against each other to a continuous conveyor trough for the conveyor chains and elements to form. 4. Device according to one or more of the preceding claims, characterized in that that the first and second parts of the conveyor (1) with the interposition of at least a trough-shaped section are connected to each other, the conveying plane at his one end is angled to its other end. 5.
