Fire protection closure along the length of rail-bound conveyor systems

摘要

The invention relates to a fire protection closure along the length of rail-bound conveyor systems, in particular monorails and overhead monorails, in walls and ceilings, in which a hollow cylinder closed at the top and bottom and made of fire-resistant material is mounted in a housing or frame arranged on or in a wall or ceiling passage in such a way that, driven by an electric motor, it can be rotated in a longitudinal axis, and the hollow cylinder has in the region of its shell an opening from which one or more guide-rail portions or track sections run radially into the interior of the hollow cylinder so that one or more running-gear units can be moved completely in the interior of the hollow cylinder, which closure is characterised in that only the cylinder shell (3) is rotatable about a vertical or horizontal axis, about the fixed inner cylinder part which accommodates the guide-rail portions or track sections (10, 11), and rail sections (6, 7, 14, 15) matched to the form of the cylinder shell are arranged in the opening (5) of the cylinder shell (3). <IMAGE>
