SUPPLY CABLE HANDLING MECHANISM AND SCRAPER CHAIN CONVEYOR CHANNEL FOR MINING THIN SEAMS

摘要

The present invention relates to a feeder cable laying mechanism and a face conveyor gate of a mining machine for thin seams used especially for cutting thin coal seams. The cable laying mechanism /6/ of the mining machine /1/ for low faces has a lower branch /6b/ of the cable laying mechanism /6/ arranged in the upper section /8a/ of gates /5/ of the face conveyor /2/ guided on guide inserts /27,28/ of a drive strand /10/ of a tensioning trolley /9/ of said cable laying mechanism /6/, wherein the return pulley /12/ of the drive strand /10/ is slidably mounted by means of a tensioner /17/ arranged in the upper section /8a/ of the gates /5/ of the face conveyor /2/. The pulling strand /11/ and the return strand /13/ of the drive strand /10/ are arranged horizontally in the guide inserts /27,28/. Tensioning of the drive strand /10/ is performed by means of the tensioning trolley /9/ and the tensioner /17/. The gate according to the invention preferably has an insert /26/ located in the upper section /8a/ of the gates /5/ which is equipped with the properly made and mounted guide inserts /27,28/.
