Abstract

The invention relates to a rotating mechanical and electrical connecting device (100) between a transport module (6) and handling and working devices in a fused bath electrolysis aluminium production plant, characterised in that it comprises a “fixed” frame (101) fitted with a hub (102), a sleeve (121) surrounding the hub (102) and capable of rotating about the hub, first (110) and second (120) “rotating” frames capable of rotating about the sleeve (121), sliding rotating electrical contacts (113, 114) between the frames and the drive systems (140, 141, 142, 150, 151, 152) to make the frames rotate with respect to each other about a common axis (103). The connecting device according to the invention enables a rotation with no angular limit between the three frames, while making a permanent electrical link between them.

Dependent claims

Rotating mechanical and electrical connecting device (100) between a transport module, typically a trolley, (6) and handling and working devices (7, 8, 9, 10, 11) in a fused bath electrolysis aluminium production plant, characterised in that it comprises:

a “fixed” frame (101) designed to be fitted to the said transport module (6) and comprising a hub (102) defining a rotation axis (103);
a sleeve (121) surrounding the said hub (102) and capable of rotating about the hub (102) and about the said rotation axis (103),
a first “rotating” frame (110) capable of rotating about the said rotation axis (103) and driving the said sleeve (121) in rotation, and designed to carry at least one handling and working device (7, 8, 9, 10, 11);
a second “rotating” frame (120) capable of rotating about the said sleeve (121) and the said rotation axis (103), and designed to carry at least one handling and working device (7, 8, 9, 10, 11);
a first plurality of sliding and rotating electrical contacts (113) each comprising at least one first member (1131) fixed to the fixed frame (101) and connected to at least one external conductor (117), and at least one second member (1132) fixed to the sleeve (121) and connected to at least one distribution conductor (118, 1181, 1182);
a second plurality of sliding and rotating electrical contacts (114) each comprising at least one first member (1141) fixed to the second rotating frame (120) and connected to at least one distribution conductor (119), and at least one second member (1142) fixed to the sleeve (121) and connected to at least one distribution conductor (1181, 1182);
a first drive system (140, 141, 142) capable of rotating the first rotating frame (110) about the said axis (103);
a second drive system (150, 151, 152) capable of rotating the second rotating frame (120) about the said axis (103).
