Title
(DE) SENKMASCHINE MIT VERTIKAL-SCHWENKWALZEN
(EN) SINKING MACHINE WITH VERTICAL SWING ROLLERS
(FR) MACHINE DE FONCAGE A ROULEAUX PIVOTANTS VERTICAUX
Abstract
(DE)
Zum Absenken von Strecken, insbesondere im untertätigen Steinkohlenbergbau dient eine Senkmaschine (1), deren Schneideinrichtung (17) aus zwei vertikal angeordneten und schwenkbaren Schwenkwalzen (19, 20) besteht, wobei diese Schwenkwalzen (19, 20) über Tragarme (21) gehalten mit dem zugleich als Widerlager dienenden Maschinenrahmen (10) verbunden und höhenverstellbar ausgebildet sind. Über die Schwenkwalzen (19, 20) werden die konvergenzbedingten Hebungen (7) vom Streckenstoß (6) zur Streckenmitte hin geschnitten und gleichzeitig durch die gegenläufig ausgebildeten Schwenkwalzen (19, 20) auf den Förderer (8) übergeben. Aufgrund der Ausbildung ist diese Senkmaschine (1) bezüglich der Schneidkräfte, wie auch der notwendigen Rückstellkräfte für die Schneideinrichtung (17) vorteilhaft gering zu dimensionieren.
(EN)
The aim of the invention is to sink sections, especially in underground coal mining. To this end, a the cutting device (17) of a sinking machine (1) consists of two swing rollers (19, 20) which are arranged vertically and pivotally and which are linked to the machine frame (10) via supporting arms (21). The machine frame (10) also serves as a skewback. Said swing rollers (19, 20) are height-adjustable. The convergence-related elevations (7) are cut from the gallery end (6) in the direction of the centre of the section and are simultaneously delivered onto the conveyor (8) by means of the swing rollers (19, 20) that operate in different directions. In a preferred and advantageous embodiment, the dimensions of the sinking machine (1) are small in comparison with the cutting forces and the requisite restoring forces of the cutting device (17).
(FR)
Pour creuser des galeries, en particulier dans des mines de houille en exploitation souterraine, on utilise une machine de fonçage (1) dont le dispositif de coupe (17) comprend deux rouleaux pivotants (19, 20) agencés verticalement, ces rouleaux (19, 20) étant maintenus par des bras porteurs (21), reliés au châssis de la machine (10) servant en même temps de contre-appui, et configurés de façon à pouvoir être réglés en hauteur. Les relevages (7) dus à la convergence sont coupés par les rouleaux pivotants (19, 20), à partir du front de galerie (6) vers le milieu de galerie, et sont transférés en même temps sur le transporteur (8) par les rouleaux pivotants (19, 20) en marche contraire. Par suite de sa configuration, cette machine de fonçage (1) offre, en ce qui concerne les forces de coupe, ainsi que les force de rappel requises pour le dispositif de coupe (17), l'avantage d'un faible dimensionnement.
