Winning apparatus guided on hydraulic self-advancing support assemblies

摘要

The winning apparatus is guided on hydraulic self-advancing support assemblies which have hydraulically vertically adjustable props 1, a floor skid 2, a roof bar 3, a gob shield 4 and a link 5. The link 5 is mounted on the waste side on a base frame 6 which encloses the floor skid 2 all round and is displaceable relative to the latter in the working direction. A two-piece, vertically adjustable winning wall 7 is supported on the base frame 6. The top and bottom strand of a double guide tube 9 is fastened to the winning wall 7. Circulating in the double guide tube 9 on the roof and floor side are the cutter slides 10 to 17 of the winning apparatus, which are integrated into a circulating flat-link chain 18. The invention is directed towards improved guidance of the cutter slides 10 to 17 and more effective transmission of the drive forces to the winning tools 17.
