ASSEMBLY OF BOTTOM PLATE OF GATE, CONTAINING BAYONET-FREE MOUNTING OF COLLECTOR CUP Russian patent published in 2022 - IPC B22D41/56 

FIELD: metallurgy.

SUBSTANCE: assembly of a bottom plate of a gate system of a metallurgical container contains collector cup (10) with protrusions (11) distributed along its side surface (10L), frame (20f) with a clip for bottom gate plate (20g), and a connecting device for receiving and connecting collector cup (10) to the frame, containing a receiving sleeve. The connecting device contains mating parts for protrusions (11) and bayonet ring (22) fixed in the receiving sleeve with the possibility of rotation around longitudinal axis (Z) of a channel of the collector cup. Channels are made along axis (Z) on the inner surface of bayonet ring (22). On the downstream edge of the bayonet ring, width (Wd) of channels is more than width (W) of protrusions (11) for their movement along channels until contact with mating parts of the connecting device. On the upper edge of the bayonet ring, width (Wu) of channels is more than width (Wd) of channels for rotation of the bayonet ring relatively to the collector cup around axis (Z) to fix the collector cup in a working position.

EFFECT: simplification of mounting the collector cup by one manipulator or one person is achieved due to the absence of a separate bayonet ring.
