摘要:
Chain guide arrangement for a mining machine, in particular for an extraction plough. The chain guide arrangement comprises a first chain passage for a load strand and a second chain passage for a return strand of a drive chain of the mining machine. At the end areas of the chain passages there are provided a drive station and a return station for the drive chain. At least at one of the chain passages a chain guide for the load strand and/or for the return strand of the drive chain is provided in a transition area to the drive station/s and/or the return station. According to the invention, the chain guide comprises a retaining pocket being open towards the drive chain and at an end face thereof being bounded by a hinge pin arranged to be transverse to a direction of movement of the chain. The chain guide further comprises a hold-down device comprising a pin seating on at least its one end face which pin seating matches with the hinge pin and is open on one side, and a locking arrangement. The hold-down device comprises a pressure face adjoining against the drive chain when the hold-down device is in a state in which it is retained in the retaining pocket and locked.
