In the case of conveyors, especially in the case of closed, reversible chain conveyors, it is necessary to these are main and auxiliary drive stations or drive and reversing stations, against each other to tension in order to fix the same and thus to keep the conveyor chain under a certain tension. In the event of a greater incidence, the funds must also be secured against slipping. Of special The importance is the bracing and fixing of such funding, which is necessary for the management of a Serve planing device. Due to the large pulling forces with which the plane is pulled, there is a risk here that the conveyor buckles sideways or is shifted out of its position when the plane is on a larger one Resistance meets. In addition, the conveyor troughs are pressed against one another by the high tensile forces. This can lead to damage to the channel connection joints in the case of insufficiently tensioned conveyors can.

The tensioning of chain conveyors, which are only moved once a day, is easy and can be done using strong chains on stamps provided for this purpose. However, the bracing of is much callous Conveyors that are used on a stamp-free dismantling front and continuously according to the dismantling progress must be moved up. For this purpose one has to deal with heavy loads in the upper and lower sections Clamping bars · attached, on which the clamping elements of the chain conveyor when moving up by means of rollers be guided. This is cumbersome and involves a lot of material. In addition, the facility is' obstructive in the routes. Attempts have therefore also been made to run the drive stations on rails, .that are attached to stamps in the face. The turning of the rails is in general through the expansion of the very cramped face area is very difficult. To avoid the mentioned disadvantages and that Bracing of the funding and the back of the same To simplify., It is proposed according to the invention,. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --place guide troughs horizontally parallel or diagonally to the rearward direction of the conveying-end station to create guide troughs, in which the vindstations of the conveyor are supported by means of guide rails attached to them and slide when the conveyor is closed. The guide troughs can be vertical or at an oblique angle be cut into the lying by milling. Since the advancement of the conveyor is proportionate If you go slowly, the cutting of the guide channels can be done at the same time as you move up take place.

In general, the guide troughs are created parallel to the rearward direction of the conveyor. Should, however the length of the conveyor can be increased or decreased, so the guide troughs can something Procedure and establishment

be made obliquely to the reverse direction. You have it in your hand, the tension and the length of the conveyor can be increased or decreased as required. The production of a guide trough can, for example, be made by a vertically or horizontally acting one Milling device take place. With the slow return speed of the funding agency and: the. shallow depth of cut is used for making the guide trough no major milling work to be done. - -. ...

The setting of stamps for the voltage of the Conveyor and moving special slide rails are superfluous if the guide troughs: so deep into the Laying cuts are made so that the heavy weight of the drive stations is sufficient to hold the guide rails to hold securely in the guide troughs.

Milling devices for the production of slots in soft rock, for example in coal seams, are known per se. Depending on the application and location of the slots, such devices are also called cutting machines or referred to as notch machines. Such machines usually have a cutting arm on. on which a rotating inclined chain is arranged. There are brackets for Cutting tools attached.

Also known is a road loading machine for use in potash mining (magazine for the Berg-, Hütten- und Salinenwesen, 1940, pages 11 and 12). This machine has a rotating milling head which is equipped with milling knives. The milling head is together with a drive motor, a drive cylinder, a guy car etc. on a preferential

bearable frame. Behind the cutter head, the cross-section of the route is cordoned off from the route by a sign. This shield rotates with the milling head and carries several blades that pick up the cut debris and throw a chute through the shield, from which it is carried away by a conveyor belt. With such a machine, a route with a circular cross-section can be driven in potash deposits. The size of the circular cross-section depends on the diameter of the rotating milling head. The invention uses milling devices of a similar design in a different technical context. An exemplary embodiment of the invention is shown in the drawing. Fig. 1 shows a chain conveyor schematically in side view; Fig. 2 shows a drive station of a chain conveyor in an end view; Fig. 3 shows a drive station of a chain conveyor in side view. With 1 in Fig. 1 drive stations for a chain conveyor are designated, which is formed from the conveyor troughs 3 and the connecting troughs 2. A skid 4 with a guide rail 5 is attached under each of the two drive stations. In the lying 6 guide channels 7 are cut perpendicularly, in which the guide rails 5 slide. On the skid! is, as Fig. 2 shows, a device for producing a guide trough attached in a lying position. This device consists of a vertically acting milling wheel 8 which is driven via a gear 9 by a motor (not shown). The traction means 10 attached to this device serves to back the conveyor. The pulling device for moving up the conveyor and the cutting wheel 8 can be driven by a common motor. The milling wheel 8 is expediently mounted pivotably on the runner 4 in order to better overcome height differences of the lying person 6 and to be able to change the direction of the guide channel at will. The milling wheel 8 can be pivoted mechanically or electrically, but it is also possible to use hydraulic or pneumatic cylinders for this in a known manner. The end 11 of the milling device is designed in the shape of a runner so that it can slide on the recumbent when the conveyor is back. In Fig. 3 a guide channel 12 cut at an oblique angle into the horizontal is shown, into which the guide rail 13, which is also connected at an oblique angle to the skid 14, engages. "Instead of the milling wheel 8 described, a horizontally acting milling device can also be used. It is possible to design the milling device as an independent unit or unit that can also be easily removed from the conveyor. It can be provided with a device by which - as is known per se - the cuttings are sucked off or removed from the guide trough by means of water by means of water Several milling devices can be connected to the conveyor for the production of the parallel guide troughs, but only one milling device can be used that can be displaced in parallel. 1. Procedure for tensioning and fixing funding in underground mining operations, in particular of closed releasable chain conveyors, characterized in that before or while lying down in the back in the rear direction of the conveyor end stations guide troughs are produced in which the end stations of the conveyor with attached guide rails slide at the back and themselves Support during the conveying operation. 2. Device for performing the method according to claim 1, characterized in that that with the end stations (1) of the conveyor one or more rigidly or pivotably arranged Milling devices. (8) are connected. 3. Device according to claim 2, characterized in that the milling devices on skids (4,14) are articulated, which are transverse to the longitudinal 4 '' direction of the conveyor at the bottom of the end stations attached and provided with vertical or inclined guide rails (5, 13). 4.
