| 摘要 |
The invention relates to a supporting frame for a stirring device disposed in a basin containing solid-laden liquid, which supporting frame can be moved up and down along a guide tube having a rectangular, especially a square, cross-section, with the aid of a lifting appliance disposed on the supporting frame, detachably fastened members being disposed on the inside of the supporting frame which are in constant contact with the outer surface of the guide tube and serve for guiding and for linear movement. A substantial reduction of the surface pressure caused on the guide tube by the guides of the supporting frame, and thus a decisive reduction in the faults caused thereby, is achieved according to the invention by the members serving for guiding and for linear movement being formed by sliding plates (5, 11) which bear against the guide tube on all sides and consist of a low-friction plastic having good wear resistance. <IMAGE> |
