Pneumatic stowing line with on-buttock discharge

摘要

Pneumatic stowing lines are composed of pipe sections connected to one another via couplings and can be shifted in the closed run. Provided at intervals in the pneumatic stowing line are line sections which are arranged in rack-like holders, can be disengaged via mechanically operated couplings and serve as a discharge pipe, the discharge pipes being pivotable in the direction of the goaf via at least one swivel cylinder and corresponding guides inside the holder. To reduce the high wear and also the non-uniform stress on the rack-like holders during practical operation, a symmetrically arranged guide (8, 9) enclosing the stowing line (1) in a fork shape and a swivel device (7) are provided inside each holder (4) in combination with couplings (13) connecting the pipe sections to one another and absorbing high restoring forces. <IMAGE>
