DE1060820B - Device for advancing a carrying element serving to guide a coal mining machine in the steep bearing - Google Patents

Description

To in the steep bedding in a sloping building with inclination of the base after the offset to die Holding the mining machine at the coal face to be mined is to be kept along the coal face and in stretched out a supporting organ (rope or chain) clamped at both strut ends at the same distance, to which the machine attaches itself by means of eyelets or grommets arranged on one of its longitudinal edges leads. After each extraction run, the Anchorages of the supporting element arranged on both struts according to the mining progress to be continuously advanced.

To facilitate the advance following the progress of mining, the traction means in the longwall and back from this conductive deflection sheaves has already been proposed, this example in to be arranged on a carriage which can be moved on rails and which has a vertical support column at each end with a threaded spindle and can thus be clamped in the section (see »The coal planer« from Rauer, 1946. pp. 48 and 49).

Another known means of advancing the anchoring follows the one arranged on the adjustment frame provided with two screw rams Deflection roller carriage automatically responds to progressive mining due to the slightly angled arrangement of the adjustment frame towards the seam. However, if the deflection roller slide has reached its highest end point in the adjustment frame, the cutting work must be stopped, the screw stamps loosened and the entire adjustment frame advanced (magazine "Schlägel und Eisen" 1950, p. 80, and the advertising leaflet "Rope cutting device" from the Henry Neuenburg company. Recklinghausen-South).

The invention relates to a device for advancing a guide for a coal-mining machine (cutting machine or planer) on the coal face in the steep storage on both Striving clamped carrying element (rope or chain) according to the mining progress using a slidable anchor block in the upper stretch and a likewise slidable one abutment in the lower section.

In contrast to the known devices, the device according to the invention has the upper end of the supporting element on the piston rod one in the anchor block, which is supported by a wall hanging against it Threaded spindle can be clamped, swiveled parallel to the footrest, hydraulically operated clamping cylinder fixed while da«; anchoring structure for the lower end of the supporting element from one for itself between the lying and hanging wall hydraulic rams arranged on both sides in the longwall which can be clamped and a guide frame attached to this Device to advance

\ slidable hydraulic ram, which can be used alone or together with the other two hydraulic Punches can be moved and clamped alternately and to which the lower end of the supporting element is attached is. According to the invention is further through the guide rods and hydraulic Guide frame formed by the stamp can be rotated and displaced around the central hydraulic stamp. Of the middle hydraulic ram is parallel to the guide frame by hydraulic cylinders can be moved to the lying position.

The advantage of the device according to the invention is that the guide sr ahme η with the two outer stamps during mining, in which the middle stamp is tightly clamped, the mining progress according to guide & rods by means hydraulic cylinder advanced to the position intended for the following cut and then can be tense.
