GERMAN PATENT OFFICE

The invention relates to cap connections for longwall mining in mining operations below Days and in particular on cap connections of the kind where, in order to create a stamp-free coal front, the cap reaching the coal face with the previous one, im Slide field is cantilevered and connected by means of expansion stamps supported cap and if desired, also rigidly and kink-proof connected

can be ίο by two caps of the interconnecting coupling pin wedges are provided on both sides, the other of which serves one of the cap to be coupled to the free orpfändung \ ⁷ and Starrmachung of the compound.

In the case of the known cap connections for longwall mining in underground mining, where for the purpose of creating a punch-free coal face, the cap reaching the coal face with the previous cap, which is located in the slide field and supported by expansion stamps Adaptation to the course of the hanging wall is connected, forms the coupling bolt for the connection of the two caps with each other also the pivot pin when pivoting the cap against the hanging wall and its swiveling away when the cap is stolen. To do this, the two have Caps in addition to the pivot bolt mentioned, a second bolt or wedge for the free one Advance deposit of the cap to be coupled, which is inclined against a relative to the longitudinal axis of the cap extending surface of the cap to be pre-pounded and the cap when it hits against

Besides that can also have another Hol / .cn or wedge be provided which the final position of the pre-pledged K; i | ipc and thus the Makes the cap connection rigid and kink-proof. With such cap connections with itself against the inclined slirii surface of the cap to be pledged The Xachtcil consists of a supporting Yorpfändkeil. that the vorzupfäiideude cap not also on the Yorpfänd ίο hung wedge and around this against the hanging wall can be swiveled.

In the case of cap connections of the kind mentioned, to which the force relates, the aforementioned Avoid disadvantage / u, sleeps the Kr lindiiug, the attack surfaces on the cap tongue or the Kappangahel. against the Yorpfändkeil when pledging, and also those who against which the Hestiege wedge rests, no longer on the face of the /, iiiitjc or the (iabel, but as part of a self-contained recess in the caps / unge oiler in the cap to train pcngabel, which is also used for the wedge recording. This enables z. l>. the Yorpfändkeil to hang up and swing open the cap to be pledged and the chest to use wedge to pivot the cap to be robbed, so that the amount previously required for this took in hormone from additional auxiliary bolts. I1 ilf-döchern or the like come into Kortfall. It is expedient here to keep the recesses in the tongue or in the tongue approximately ^c larger than the cross-section of the wedges to be introduced therein. In the drawing the general gallery is in front blow in a Ansführungsbcispjel schematically illustrated. Hig. ι shows the front view of a cap connection, in which the coupling parts are butt-welded to the barrel profile; are with the representation of the coupling hoi / cn and Yorpfändkei! as well as cover plate omitted; Hig. 2 shows a horizontal section through the center of the cap according to] · iμ. 1 with inserted wood and wedges, while
Hig. 3 a section along the line AA and Hig. -I put one after the first line /> '- /> the Hig. ι represent. In the Higuren, 1 denotes the coupling fork, j denotes the Ku | iphuif, ^r szun ^ e, while 3 fio denotes the Knpp! Unt; sbolzcn and.) Denotes the coupling wedges. From the I ^; It can be seen that the coupling wedges 4 lie in closed recesses ς of the Kappenzungeeiides 2, which are slightly larger in diameter than the cross section of the wedges 4, or that the claws of the tongue ends against which the coupling wedges rest, parts of closed recesses in the Form tongue end. The coupling bolt is expediently tapered so that it can be easily loosened under the load of the mountains. Liei of the exemplary embodiment shown, the cap connection is left and right a coupling wedge 4 is arranged from the coupling bolt 3. Of these coupling wedges 4, the wedge to the left of the coupling pin 3 is used to to pledge the crib to be coupled and to move and press against the hanging wall while the wedge to the right of the coupling bolt 3 is used to determine the final position of the coupling bolt To set the cap, the cap connection as rigid and kink-proof if desired do. From the graphic representation it can also be seen that, depending on whether one or other wedge 4, el. h. the Yorpfändkeil or Kestlegekeil, drives the angular position of the coupling parts or the caps can be changed to each other.
