Device for immobilizing the chute on the end of the journal in a blast furnace loading instrument

摘要

An apparatus for immobilizing a spout at the end of a trunnion within a blast furnace charging facility comprises a swiveling material distribution spout (1) which engages a receptacle (21) formed in the trunnion. And an eccentric nipple (31) that engages the spout lug to immobilize and hold the lug at the bottom of the receptacle and locking means (4) for rotationally locking the pin. It is connected to the support trunnion (2) by a lug (11) which is immobilized by a pin (3) provided for. Each pin is provided with means (32) for adjusting and tightening its rotation on the outside, opposite the nipple, so that the nipple can be pressed against the spout lag with sufficient force from the rotation of the pin, and locked The means comprises an index plate (41) connected to the end of the pin (3) for rotation, the plate (41) further with corresponding teeth (421) of the lock (42) fixed to the trunnion. The lock comprises teeth (416) arranged to cooperate in such a way that the pin can be rotationally immobilized at a plurality of circumferential positions of the pin. [Selection] Figure 4
