Zusammenfassung: | The invention relates to a hydraulic block anchoring for an underground haulage and/or winning plant, in which the hydraulic anchoring cylinders (19) are connected in an inclined position in an articulated manner between prop abutments (12) and the haulage and/or winning plant (10). In order to create a light anchoring device which is comparatively less complicated in construction but can be used in as versatile a manner as possible, prop abutments (12) are used in which only a single hydraulic supporting prop (14) is supported on a floor skid (13) in a foot joint, a connecting joint (22) arranged laterally next to the foot joint at the floor skid (13) and intended for the anchoring cylinder being offset in the shifting direction relative to the centre of the foot joint in such a way that, when the anchoring cylinder is extended halfway, its lengthened cylinder axis passes approximately through the centre of the foot joint or the perpendicular to the foot-joint centre. In this way, the moment produced at the prop abutment (12) by the anchoring cylinder (19) is kept low and unfavourable torsion or deformation forces are prevented from being passed into the prop abutment. In addition, the prop abutment is of symmetrical design and is provided here with joint trestles (18), arranged on either side of the prop, for the connection of at least one anchoring cylinder (19) and if need be a chain (31) via which the prop abutment can be shifted by means of the anchoring cylinder. |
