Definitions

  • the invention relates to a repair and assembly car for nuclear facilities. These wagons are to be used for areas exposed to radiation. That is why, for example, the Düsseldorf Nuclear Research Center has developed such a car that is operated entirely by remote control. The car can be moved on difficult terrain with the help of caterpillars, but its possibilities of use are limited, for example, by the fact that the operating personnel only have a limited view, in particular via television monitors. Therefore, only relatively simple work can be carried out with it.
  • the invention is based on the object of being able to repair or replace components at risk of radiation, for example from hot cells in reprocessing plants or fuel element factories, especially pipelines, pumps, valves, filters, etc., without the personnel being too severely hampered by shielding is.
  • the solution to the above problem consists in the special design of a repair and assembly vehicle, in such a way that a vertically adjustable and preferably also rotatable platform is arranged on a movable lower part, that the platform carries a shielded cabin, which is a Part of the platform extends that in the wall of the Ka bine one or more manipulators are arranged, the control members are in the cabin and the working members over the adjacent to the cabin part of the platform.
  • the carriage can advantageously be designed so that the platform carries a crane.
  • the crane can sit on or on the cabin, so that its structure is used as a supporting structure.
  • the term crane also means hoists other than those with a boom.
  • the carriage can have a driven undercarriage, control elements in the cabin being assigned to the undercarriage. This results in a simple chassis if the path of the car is predetermined by rails according to the circumstances.
  • the car according to the invention can also be equipped with steerable wheels or, like the known car, with caterpillars.
  • a lock is expediently assigned to the car for entering the cabin. This means that the vehicle standing in a radiation-endangered environment can be entered by the operating personnel without being exposed to the ambient atmosphere of the vehicle.
  • the cabin should be equipped with oxygen cylinders with respiratory protection in order to ensure that the radiation-free air supply to the The cabin fails to have a bridging option until the staff alight.
  • the new car can include travel, lifting and rotary drives integrated in the lower part.
  • the height-adjustable platform should extend to the top edge of frames in which components that are susceptible to repair must be treated.
  • the screening walls of the cabin should be transparent over a large area, preferably in the form of single or multi-layer lead glass windows.
  • the manipulators can be provided with various interchangeable tools. In principle, they are designed as is known from hot cells, so they preferably work as master-slave manipulators with pressure medium support.
  • FIG. 1 shows the floor plan of a reprocessing plant
  • FIG. 2 is a vertical section through the plant.
  • Fig. 3 a part of the carriage is shown in a vertical section on an enlarged scale.
  • the concrete building 1 shown in FIG. 1 belongs to a reprocessing plant for fuel elements.
  • the components housed in the room 2 are arranged in racks 3, which are set up on both sides of a central aisle 4 along the walls 5 and 6.
  • the racks include, for example, containers, pipes and valves for dissolving the spent fuel and for chemical treatment of the predominantly liquid substances.
  • 2 shows that the frames 3 taper upwards at about half the height. This improves the accessibility for a carriage 10, which can be moved in the aisle 4 along rails 3 along dash-dotted lines 11.
  • the carriage 10 is shown in the end position in which it is connected to a personnel lock 14. Seals 15 ensure a gas-tight connection between the carriage 10 and the lock 14.
  • the carriage 10 comprises a lower part 20 which runs on the rails 11 with wheels 21.
  • the wheels are actuated by a drive, not shown, the control elements of which are accommodated in a cabin 23 with shielded walls 24.
  • the cabin 23 sits on a platform 25 which is arranged on the lower part 20.
  • the platform 25 can be rotated once about the axis 26 indicated by dash-dotted lines, as shown by the arrow 27.
  • the platform 25 is adjustable in height. In Fig. 2 the highest position at 30 is shown in dash-dot lines.
  • the cabin 23 is made of shielding material. As shown in FIG. 1, it only covers a little more than half of the platform 25. Therefore, there is an area 32 located next to the cabin 23 that functions as a working area platform is to be viewed. The wall facing this work platform is clearly visible with shielding lead glass windows 34.
  • manipulators for example 35, 36 and 37, which can be operated from inside the cabin 23, for example with the master device 40, so that the tools 41, 42 and 43 held by the manipulators are the same as those shown in FIG. 3 Carry out the movements indicated by the arrows. They all cover at least area 32 of the platform. But some also go beyond that.
  • a hoist 46 is arranged on the top 45 of the cabin 23, the lifting mechanism 47 of which carries a crane hook 48 and is seated at the end of a telescopic arm 50 which is adjustable in the direction of the arrow 51.
  • a storage area with boxes 55 is provided in the lateral area, designated 54 in FIG. 1, next to the cabin 23. Interchangeable tools can be deposited there with which the manipulators can be equipped if necessary.
  • the carriage 10 can be anchored to these with hooks 57.
  • Such gripping members result in greater stability for the application of forces, for example for loosening nuts or for sawing or bending pipes, so that the carriage itself can be carried out relatively easily.
  • a frame 3 with a trolley 58 located on the ceiling of the room 2 for Repair work has been set from the basic position to position 3a in gear 4. This makes it possible to reach into the frame from the side.
  • the platform 25 is rotated in the direction of the arrow 27, so that the manipulators 35, 36 and 37 can be used optimally.
  • the front of the cabin 23 is also provided with a nozzle opening 60 which can be pivoted in two mutually perpendicular planes, as indicated by the arrows 61 and 62. This means that a jet of decontaminating liquid can be directed onto components without the direct use of personnel, so that contaminating waste can be flushed out of room 2.
