Description

Beschreibung des Widerlagers zum Ausheben der Außenkufen bei hydraulischem Dreifachstreckenausbau ( T-Widerlager ) Description of the abutment for lifting the outer skids in hydraulic triple-section construction (T-abutment )

Stand der Technik, im untertägigen Bergbau ist, verstärkt in den Bereichen der Streb-Streckenübergänge, sogenannte Streckenschilde einzusetzen. Es gibt hier mehrere Alternativen.
Die nachfolgende Erfindung bezieht sich auf Dreiersysteme ( Triple - Ausbau ).The state of the art in underground mining is to increasingly use so-called road shields in the areas of the longwall crossings. There are several alternatives here.
The following invention relates to triple systems (triple expansion).

Zur Vorbereitung des Vorziehens des Ausbaus, ist in der Regel eine mehr oder weniger intensive Reinigung der Streckensohle erforderlich.In preparation for the advancement of the expansion, a more or less intensive cleaning of the track bed is usually required.

Durch den Einbau des (der Erfindung) T- Widerlagers, daß bei der Fertigung schweißtechnisch intregiert wird, ist ein Anheben der Außenkufen ohne zusätzlichen Arbeitsaufwand möglich. Dadurch entfällt beim Vorziehen die Reinigungsarbeit.By installing the T-abutment (of the invention), which is integrated by welding during production, it is possible to lift the outer skids without any additional work. This eliminates the need for cleaning when pulling them forward.

Figur 1 zeigt schematisch den komplett gestellten Streckenschild. Figure 1 shows a schematic of the completed route sign.

Figur 2 zeigt das T- Widerlager in Funktion. Der mittlere Rahmen ist voll gesetzt. Die Außenrahmen werden nun parallel eingeraubt, bis die Kappen voll auf dem Widerlager aufliegen. Durch nicht unterbrechen des Raubvorganges, werden über die Ringflächen der Stempel soviel Kräfte eingeleitet, daß sich die Außenkufen um das erforderliche Maß aus dem Haufwerk herausheben. Über die Schreitwerke werden die Außenrahmen nun gleitend über die Rollen vorgezogen, ausgerichtet und wieder
gesetzt. Figure 2 shows the T-abutment in operation. The middle frame is fully set. The outer frames are now screwed in parallel until the caps are fully seated on the abutment. By not interrupting the screwing process, enough force is introduced via the ring surfaces of the stamps that the outer skids are lifted out of the pile by the required amount. The outer frames are now pulled forward over the rollers, aligned and then pushed back into place by the walking mechanisms.
