The invention enters a »pressure medium-actuated pre-pile stack, the one at the coal end of a pre-pledging cap is arranged «

Vorpfändatempol of this type are then pledged * when the hanging wall is in use and has to be seeped right up to the excavation face.

) Ilözen, which is tefelini-like, may be sufficient to retract the advance deposit stamp, which is attached to the end of the cap protruding over the conveyor, so that it moves away from the kiagendi with its base plate in order to allow a flat mining machine to pass through, this path is a shallower one yet to win without the stamp after the screws to lift across the conveyor * store it there and bring back to its previous location after the passage of the engine I ¹ Isz and not feasible · at higher-building mining machines Vm the required free tree for the machine , the stamp can be swiveled towards the cap, with which it is normally permanently connected

It is advantageous to install a pressure-actuated working cylinder between the plunger and the cap, which swivels the plunger out of the gate position towards the cap and vice versa. With the help of such a pressure-actuated working cylinder, the hood and the setting of the pre-pledging stamp are fully mechanized, with the necessary movement processes either being triggered individually with the help of a corresponding control or automatically controlled, for example from the advancing mining machine, Pa for swiveling up the The gate lock, the working cylinder can be held relatively easily

A simple and reliable working arrangement is obtained when the working cylinder is set with a set of gate lockets assumes a position inclined downwards in the direction of the punch and is articulated at both ends In this way, the arrangement can be matched to the most favorable solution in each case, taking into account that the force to be expended to swivel up the punch all the more

The lower the lower the lower end of the working cylinder or its piston rod is connected to the punch is »while, on the other hand, the one above the funding available Space is all the more narrowed, the deeper the junction arranged between the working cylinder and pre-pledging stamp will.

In order to be able to use the To be able to use the same working cylinder to swivel up the pre-pledging stamp is the connection between the punch and the working cylinder or its piston rod preferably designed in the manner of a link slide · The working cylinder can be hinged to the side of the punch » Since the other end of the working cylinder is mostly in the area of the ram on the mountain side next to the conveyor is also here, based on the center line of the cap, lateral attachment required · Nevertheless, the usual caps are usually so wide that a Working cylinder of the eligible for this purpose Size despite being attached to the side of the stamps from the Cap is protected *

The invention is explained in greater detail below using a volume of figures explained.

It shows

Fig. 1 is a rare view of a longwall construction

with the pre-pledging stamp in the working position,

rig. Figure 2 is a plan view of Pig1,

3 a representation corresponding to FIG. I, in which the pre-pledging stamp is retracted is,

fig »4 the same arrangement as Pig · 3» but after swiveling the pre-pledging stamp to the cap and

a vertical section through the joint between the punch head and the pledge cap in an enlarged view.

Pig »1 shows a longwall structure formed by two punches 1 and 2. The punches χ ^ ag are connected to one another via a lying cap. "The punch 2 on the mountain side has a cap 4" to which a pre-pledging cap 5 protruding in the direction of the mine shaft is connected approximately in the middle above the pile that is kept open. The cap 5 rests on the punch 1 · It is secured by the hanging wall located above the conveyor 6 installed parallel ζ around the coal face.

In the case of broken hanging walls »the one with a stamp-free dismantling front can not be worked, to secure the pre-pledging cap 5 according to the proposal of the invention, a pre-pledging stamp 7 is used, which is at the front end of the cap 5 at 8 is articulated with his head »

To bring the pre-pledging stamp 7 "which is extended and retracted in the usual way with the help of pressure medium, into a position in which the passage of the mining machine is not obstructed, a working cylinder 9 is provided which is attached to a joint at its end on the mountain side 12 is fastened to the cap 5, while its piston rod 10 engages at its front end with a joint 11 on the pre-plunger 7. The working cylinder 9 is as shown in Fig. 1, disposed between the cap and the lower punch of the punch 7 so as for set Vorpfändstempel 7 to the horizontal inclined ver · runs · The arrangement of the Arbeitezylinüers $ is chosen so that over the conveyor 6 enough tree remains and accordingly larger lumps of coal can be atotranaporiieit undisturbed *

The working cylinder 9 can, if necessary, be telescopically extendable in several ways »if the working conditions require it .

From £ * ig «2 it follows that the working cylinder 9 laterally placed next to stamps 1 and 7 1st. The usual Caps 5 are usually enough to protect the working cylinder 9 to slit

Zn Pig "2 a control device can be seen at 15" with their help, the operations explained below by triggering an operator

When the mining machine approaches the pre-deposit stamp, which is initially in the position " 1 ", the stamp 7 is retracted either by actuating the control 15 or by automatic remote control, so that the Uhtersteapel lifts from the lying and the arrangement the Position according to Fig * 2 assumes

Then the working cylinder 4 is retracted »so that the Vorpfändstempel 7 rotates in the joint 8 and under the cap · At this stamp, the Pig. 4 shows is space completely free between the conveyor and the working face, so that the Extraction machine can drive through without hindrance.

Immediately after the passage of the mining machine will be the operations explained last in reverse order repeated, i.e. » the working cylinder 10 is extended again so that the punch 7 is in the Pig position. 5 occupies, whereupon the punch 7 is extended and placed under setting pressure.

Pig · 5 shows an exemplary embodiment for the formation of a Joint on the head of a pre-pledging stamp. Here is with 7 ' the upper stamp of the pre-pledging stamp ". The cap is equipped with bearing eyes at the front end" by which passes through a bolt 16 which movably connects an intermediate piece 15 to the cap. Bas intermediate piece 15 under- * engages at 15 'the head piece 17, which is in the intermediate piece 15 * can turn. ”Since the joint described, the The top of the head piece 17 of the punch 7 can place against the underside of the cap 5 'when the punch is set the hinge pin 16 is not claimed when bracing the pre-pledging stamp, so that despite the hinge connection the full setting load can be transferred as with a normal punch.
