An assembly for remotely handling an electrical plug connector, including a ottom block, including a crane hook attachable to a crane, a first plug member fixed to the bottom block and electrically connectable to a power supply, a second plug member electrically connected to a load, a retaining device retaining the second plug member such that electrical coupling and decoupling between the first and the second plug member can be effected by mere movement of the bottom block in the horizontal and the vertical plane. When the first and second plug members are vertically aligned, coupling and decoupling can be effected by mere lowering and raising of the bottom block. The retaining device has parallel prongs with recessed surface areas to hold the second plug member, alternatively, in a locking position and a withdrawing position. The second plug member has a spherical thickened contour portion acting as a pivot enabling it to swing into alignment with the first plug member. The second plug member can be moved between the locking and the withdrawing positions by a horizontal shifting motion of the bottom block. The second plug member can be removed from the retaining device when in the withdrawing position but not when in the locking position. When the second plug member is being removed, the crane hook is free to grasp an eye of an operational equipment.

The invention is directed to remotely-controlled manipulator carrier systems for use in maintaining and servicing process equipment housed in large-area cells affected by radioactivity wherein industrial processes are conducted. The cells are part of a nuclear facility for reprocessing irradiated nuclear fuel materials. The process equipment is arranged along mutually adjacent walls of the cell and so defines a canyon-like passageway extending in the direction of the longitudinal axis of the cell. The system includes a first overhead bridge crane having a trolley movable thereon in a direction transverse to said longitudinal axis. The trolley includes a hoist for lowering and raising a hook for engaging and moving a component of the process equipment in a first vertical plane transverse to said axis. A second overhead bridge crane is disposed beneath the first bridge crane. Tracks are provided for guiding the bridge cranes in the enclosure in respective horizontal planes and in the direction of said longitudinal axis. The second overhead bridge crane includes an elongated supporting member arranged transversely to said axis above the passageway and engaging the track for movement therealong. A manipulator assembly includes a mast connected to the elongated supporting member and extends downwardly into the canyon-like passageway from the supporting member. The supporting member and the mast conjointly define a second vertical plane transverse to said axis. The manipulator assembly further includes a manipulator or performing manual-like operations on the process equipment, the manipulator being mounted asymmetrically on the mast so as to be on one side thereof and in a third vertical plane transverse to said axis. The first bridge crane is movable along the track to bring the first vertical plane into coincidence with the third vertical plane so as to permit movement of the hook in the third vertical plane clear of the transverse elongated supporting member whereby both the manipulator and the hook can be brought simultaneously to a predetermined work location at the process equipment.

The invention is directed to a remotely-controlled remote handling arrangnt for use in large-area radioactively-charged cells of a facility for reprocessing irradiated nuclear fuel materials. The remote handling means includes a travelling bridge crane and a manipulator carrying apparatus arranged in a plane below the bridge beam of the crane. To improve the self servicing and internal maintenance thereof, the arrangement is made up of various assemblies. The movable assemblies can be separated from their travelling chassis frames. The drive units for driving the chassis frames stay with assemblies when the latter are removed. Accordingly, chassis frames are left on the bridge beam or guide member without their drive units.

Remotely-controlled remote handling arrangement for a large-area cell of

The invention is directed to an arrangement for interconnecting a first pality of conduits with a second plurality of conduits such as conduits of the kind utilized in nuclear facilities. Maintenance work in large-area hot cells subjected to radioactivity is conducted with remotely-controlled apparatus that is movable within the hot cell. The conduits must be disconnected and connected again with remotely-controlled apparatus. The connection should be completed quickly and effectively. For this purpose, conduit end portions of the conduits which are to be connected are arranged on a fixed supporting bracket. The two sets of conduit end portions which are to be interconnected curve continuously away from the bracket to define an angle of ninety degrees so that the open terminations of the one set of conduits are spaced from the open terminations of the other set of conduits and the axes of the conduit end portions are mutually parallel. A separate connecting block has a plurality of substantially U-shaped conduit segments cast in place therein so as to be one parallel and adjacent to the other. The open terminations of the U-shaped conduit segments of the connecting block face the open terminations of the curved conduit end portions. The connecting block can be drawn tightly to the curved conduit end portions by suitable holding means.

Arrangement for interconnecting conduits

Remotely-controlled manipulator carrier systems are used in large-area hot ells such as a facility for reprocessing irradiated nuclear fuel materials. The system is used to perform manual-like operations on the process equipment in the hot cell which is disposed in racks along two longitudinally extending walls of the hot cell enclosure, the racks being filled with process equipment and defining a passageway in the direction of the longitudinal axis of the enclosure. The system includes a vertical guide column which is connected to the bridge beam of an overhead bridge crane. A support is mounted on the guide column for movement up and down the column. An extendible arm is cantilever-mounted on the support and has a manipulator or other remotely-controlled apparatus at its outer end. The extendible arm is to be subjected to a minimal bending moment when work is done in the racks containing the process equipment. For this purpose, the guide column is mounted at its respective ends between rotating upper and lower plates aligned to rotate about a common vertical rotational axis. The upper plate is rotatably mounted on the bridge beam; whereas, the lower plate is rotatably mounted on a base platform movable along a track on the passageway. The guide column is arranged between the upper and lower plates so as to be eccentric with respect to the vertical rotational axis whereby the guide column is movable, with the rotation of the upper and lower plates, to the racks on the left side of the passageway or to the racks on the right side thereof, as desired, and into proximity to the process equipment thereby reducing the distance to which the extendible arm has to be extended to permit work on the process equipment.

Remotely-controlled manipulator carrier system for a large-area cell of

A large-area cell for reprocessing irradiated nuclear reactor fuel elements ontains racks in which process components and connecting conduits for the latter are arranged. The arrangement of the invention connects the conduits of a rack with a plurality of supply conduits outside of the cell which have end portions that penetrate the interior wall of the cell. When the racks are assembled and disassembled, the conduits leading to the process components contained in the rack have to be disconnected from the supply conduits. The conduits should be connected and disconnected rapidly and surely by means of remotely-controlled manipulating apparatus. For this purpose, the arrangement of the invention for interconnecting conduits includes two terminal blocks each having a plurality of passages formed therein. The two terminal blocks are connected to each other by conduit segments which communicate with corresponding ones of the passages in the blocks. The free ends of the passages in the blocks terminate in a common surface thereof and define a predetermined pattern which corresponds to the pattern of the conduit end portions in the rack on the one hand and, to the conduit end portions at the cell wall on the other hand. The two terminal blocks and the conduit segments conjointly define a portable unit which is removable from and returnable to a rest position whereat the unit connects the wall conduit end portions with respective ones of the rack conduit end portions. The free ends of the terminal blocks, the conduit end portions at the rack, and the conduit end portions at the wall are aligned by centering arrangements.
