Description

The invention relates to a docking device for connection a transport and / or storage container to one Lock opening in a wall between a radioactive loaded work space and one located below Transport space according to the preamble of patent claim 1 or according to the preamble of claim 17.

A docking device of the type mentioned is for example from European patent application EP 0 340 488 A2 known. The docking device is used for connection one in the transport space by lifting it from below to the Sluice opening leading transport and / or storage container to the work area and the protection of the outside surface of the primary cover before contamination. The well-known docking device has a bell-shaped closure device on to lift the primary cover from the transport and / or Storage container from above onto the lock opening is put on. The primary cover is gripped by a gripper and raised, being taken inside a bell becomes. The bell with the primary cover is then away from the lock opening and in the work room switched off. Then the inside of the transport and / or Storage container accessible from the work area, so that a Loading or unloading of fuel elements, fuel rods or others radioactive substances can be made.

The known docking device has a number of Disadvantages on. Lifting off the primary cover and lifting it up inside the bell happens with the help of a Spindle drive, the gripper for gripping the lid is attached to a guide column of the spindle drive. The Guide column sits on a spindle nut, and the Spindle nut is turned by turning a puller spindle on and moved down. The spindle drive together with the puller spindle and the spindle nut is located above the bell in the Working space. The guide pillar is through the ceiling of the Bell passed through. If it is partially or completely lifted primary cover to a failure of the spindle drive, for example by "eating" the spindle nut, the primary cover raised inside the bell cannot lowered more onto the transport and / or storage container become. Other reasons for a spindle drive failure can also result in mechanical damage to the device when transporting them to and from the work area a drop position. Neither the primary lid inside the bell and the guide pillar are from the work area accessible and movable with remote handling tools. Maintenance personnel enter the work area partially or completely lifted primary cover due to the then increased radioactive radiation is also not possible.

Another disadvantage of the known docking device is in that it led from below to the lock opening Transport and / or storage containers opposite the Axis of the bell-shaped locking device positioned exactly must be so that the permissible small misalignments can be compensated for and the gripper Primary cover can grip securely. This is usually a Repeated repositioning of the transport and / or storage container required on the transfer car in the transport space, what a longer handling time of the personnel close to the container makes necessary. Another disadvantage of the known Docking device is that during the time in the bottom of the transport and / or storage container the lock opening is docked, the positioning of the Container opposite the gripper located in the bell cannot be controlled exactly. Through misalignment may cause the entire device to lift off or a chip pull when lifting the primary cover or even a lid crash. When replacing the lid are damage to the sealing surfaces and an incorrect one Locking possible.

The object of the invention is to provide a docking device create a more reliable lifting and lowering of the primary cover.

This object is achieved by a docking device solved with the features of claim 1. Furthermore, the task by a docking device with the Features of claim 17 solved.

A first embodiment of the docking device according to the invention for connecting a transport and / or storage container to a lock opening in a wall between a radioactive work area, especially one α, γ and / or n cell, and one arranged below Transport space has a locking device with one of the Working space can be placed on the lock opening and this covering bell and with one attached to the bell Lifting device for lifting and lowering the primary cover inside the bell. The lifting device has at least one led vertically through the bell Lifting rod with a device fixed inside the bell for coupling to the primary cover and one with the Lift rod coupled lifting drive for vertical movement of the Lifting rod on. According to the linear actuator is outside the bell over a detachable with the help of a manipulator Coupling device connected to the at least one lifting rod. In addition, the at least one lifting rod has outside the bell a device for coupling a lifting device to raise and lower the lifting rod. On Manipulator and a lifting device (crane) are in the work area operationally for moving the bell and for removing or Loading of the transport and / or storage containers available. As a result, the solution according to the invention has the advantage that a safe lowering even if the linear actuator fails of the primary cover remains possible. After a mechanical The linear actuator can fail in the work area existing manipulator can be used to at least to decouple a lifting rod from the lifting drive. At the same time the lifting rod is attached to a lifting device (e.g. the cell crane). After decoupling the lifting rod is from the failed lifting drive the primary cover attached to the lifting rod is slowly lowered and the container closed again. After closing of the transport and / or storage container Work space to be entered by the maintenance personnel, so that a repair of the failed linear actuator is possible is.

In a preferred embodiment, the lifting drive comprises at least one mounted on top of the bell Lifting spindle drive, the column of which runs parallel to the lifting rod is. Two lifting spindle drives are preferably symmetrical arranged on opposite sides of the lifting rod.

In a first preferred embodiment, the releasable coupling device connected to the linear actuator, vertically movable console. In a coupled normal position is a carrier connected to the lifting rod on the console and is positive and / or non-positive connected to the console. In a decoupled position the carrier can be moved vertically past the console. If a spindle drive is used as the linear actuator, then the Console firmly coupled to the spindle nut; when using The console consists of two lifting spindle drives two console assemblies, each connected to a spindle nut; the two lifting spindle drives are in this Case moved synchronously.

In one embodiment, the carrier can be coupled in the Normal position by using the manipulator releasable securing element, for example by a Screw connection, attached to the console. The Screw connection provides a safe in the normal operating stable Connection between the carrier and the console.

The carrier is preferably after the connection has been released rotatable with the console around the lifting rod. The carrier can in this embodiment one or more support arms have on one or more console assemblies rest, with each console assembly with a vertical Stroke drive is connected. After loosening the connections the support arms with the console assemblies can Carrier arms can be rotated around the lift rod until they reach one position occupy in the vertical between the console assemblies can be moved through.

In a second preferred embodiment, the releasable coupling device with the linear actuator, for example with two lifting spindle drives, connected vertically movable console. On the at least one lifting rod attached a sleeve, which has a projecting approach having. At the console is one with the help of the manipulator Movable gripping device attached in a coupled Normal position engages under the approach of the sleeve so that the at least one lifting rod on the at the Console held gripping device rests, the Sleeve with the neck in a decoupled position on the Console with the gripping device can be moved vertically past can. The projecting approach of the sleeve is preferably radially in front of their entire outer circumference. The gripping device preferably has two radially movable to the sleeve Gripping plates in the coupled normal position reach under the neck and at least partially the sleeve enclose. The two gripping plates are preferred guided in a guide of the console and can by a by the manipulator actuating device radially can be moved towards and away from the sleeve.

In a preferred embodiment, the Gripping plates claw-like the approach of the sleeve such that in the coupled position the bell with the help of the at least a lifting rod attached device for coupling a lifting device can be raised. At this Embodiment serves the device attached to the lifting rod for coupling a lifting device (crane eye) both for lifting and lowering the lifting rod in the decoupled Fall (accident) as well as for lifting and transporting the entire bell including the linear actuator and the primary cover ice raised in the bell. This eliminates the second device for coupling the lifting device (Crane eye).

This is an advantageous development of the invention characterized in that the lifting rod by a in the Wall of the bell rotatably guided guide passed through is that the lifting rod opposite the guide is not rotatable, and that a rotary actuator on the guide attacks to turn the lifting rod. This prevents an unintentional twisting of the lid and allows a precise closing of the transport and / or Storage container even in the event of a stroke drive accident. With the The rotary actuator is activated before the primary cover is gripped and lifted the correct orientation of the gripper is set. This remains even after the primary cover has been lifted off received in the bell. Even after decoupling the The lifting rod of the lifting drive cannot be turned, so that the primary cover is positioned with the help of the cell crane can be lowered.

In this embodiment, the lifting rod preferably has a non-circular cross section with a continuous, no corner outer contour, the The guide lies close to the outer contour of the lifting rod. On such a profile of the lifting rod is on the one hand non-rotatable, on the other hand, it can be well carried out by the Seal the ceiling of the bell, causing contamination contamination prevented. The lifting rod preferably has one Polygon cross section with rounded polygon corners. Such a profile is available by default and therefore relatively inexpensive. In alternative embodiments a lifting rod with an elliptical outer contour or two or more parallel and symmetrical to the central axis of the Bell guided lifting rods with cylinder profiles used become.

In an advantageous development, at least inside a guide channel for supply lines to a lifting rod one inside the bell on the coupling device observation camera mounted on the primary cover his. This allows sensor or camera-based Positioning of the device for coupling to the primary cover (Gripping device). This increases reliability and avoids cover falls and damage to the sealing surfaces the container.

In the second inventive solution of the above Task has the docking device for connection a transport and / or storage container to a lock opening in a wall between a radioactive one Work space and a transport space underneath a locking device with one from the work area can be deployed on the lock opening and cover it Bell on. The closure device also has a Penetrating wall between transport space and work space cylindrical receptacle into which the bell can be inserted is. The transport and / or storage container that is in the transport space brought up by lifting from below and to the Lock opening is connected to a bottom the cylindrical receptacle can be tightly coupled. The cylindrical Recording can be moved horizontally over a large area and with an actuator for positioning opposite coupled to the transport and / or storage container. The Accuracy of container pre-alignment on the transfer cart in the transport channel before lifting can be reduced become. This simplifies handling and reduces the Handling time of the operator on the container, what the Radiation exposure of staff reduced. The positioning the cylindrical receptacle can also with the help of Inside the bell positioned camera directly monitored and actively regulated.

Preferably, the bottom is cylindrical Recording an annular, flat end face, a transport and / or storage container on the end face can be tightly coupled with its end face or an adapter ring is. Coupling via flat end faces allowed a subsequent horizontal positioning of the recording with the top of the container or adapter ring attached.

A preferred embodiment of this docking device is characterized in that the wall between the transport space and work space a floor of the work space and comprises a ceiling structure of the transport space, and that the cylindrical holder on several on the ceiling construction attached bearings. In contrast to State of the art, in which the closure device supports the floor of the work area, the load is transferred in this embodiment over the ceiling of the underlying Transport space. Such a construction is easier to maintain, since they do not have the operating status contaminated transport space is accessible and during revisions can be completely drained into the transport channel. The overall height in the work area is also reduced. The shield in the lid area also improves because in Connection with the one matched to the diameter of the container Adapter ring existing gaps can be reduced.

A further development of the embodiment in which the cylindrical Has an annular, flat end face, is characterized in that the annular, flat end face of the receptacle at least one inflatable Has seal. It is inflated after positioning and seals the end faces. This inflatable Sealing creates a contamination barrier.

Advantageous developments of the invention are in the Subclaims marked.

The cylindrical receptacle 4 dresses the lock opening and can be moved horizontally in this lock opening. The between the inner wall of the lock opening and the Outer wall of the receptacle 4 resulting gap is both in Area of the floor 8 of the work space 2 as well as opposite the ceiling structure 9 of the transport space 3 sealed. The receptacle 4 lies on several of the ceiling construction 9 attached bearings 10 on. Height-adjustable serve as bearings 10 Ball casters. For positioning the cylindrical Recording 4 in the horizontal plane grab the bottom the cylindrical receptacle 4 in the transport space 3 several Actuators 11 on. These allow a horizontal one Shifting the cylindrical receptacle 4 by several centimeters, in the preferred embodiment, for example up to 7 cm. On the underside of the cylindrical holder 4 an annular, flat end face 12 is formed. On this end face 12 is the end face 14 one on the Transport and / or storage container 13 placed adapter ring 38 tightly connectable. The adapter ring 38 is on the Container 13 placed and has on its underside to the container sealing gasket. The adapter ring 38 is used to compensate for different container sizes. In the end face 12 of the receptacle 4 are two annular inflatable Seals 15 introduced, which after docking of the container 13 are inflated and a redundant contamination barrier create.

The bell 5 has a cylindrical side wall 16 and a ceiling plate 17. After inserting the bell 5 in the cylindrical receptacle 4, the side wall 16 is complete enclosed by the receptacle 4. An outwardly protruding one Projection 39 lies on the upper outer edge of the bell 5 an upper end face of the receptacle 4. Between the Projection 39 and the upper end face of the receptacle 4 two seals are provided. The bell 5 is firmly in the Recording 4 held. To position the bell 5 are three centering bolts 40 on the cylindrical outer surface of the Protrusion 39 attached to the corresponding receiving holes engage in the end face of the receptacle 4.

On the ceiling plate 17 of the bell 5 is the lifting device 6 mounted. The lifting device 6 has a vertical lifting rod 18 passed through the ceiling plate 17. At the lower end of the lifting rod 18, a gripper 19 is attached. The gripper 19 is used to grip the primary cover 7 of the container 13 on a pre-assembled on the primary cover 7 Claw mushroom 20 lowered and then rotated by 15 ° in order to Coupling the gripper mushroom. After safely coupling the The gripper 19 can move the primary cover 7 upwards the lifting rod 18 can be lifted from the container 13.

The lifting rod 18 is secured against rotation in a guide 21 stored and rotatably suspended on the lifting device 6. For this purpose, the lifting rod 18 has a polygonal cross section with rounded polygon corners. (The cross section the polygonal rod is shown in Fig. 3.) The guide 21st is close to the polygon outer contour of the lifting rod 18 and is sealed with two radial seals. The leadership 21 is rotatable in the ceiling plate 17 into a first bearing 22 used, which in turn rotatably in a second bearing 23rd is recorded. The bearing is with two radial seals sealed. The rotatably mounted guide 21 engages first rotary actuator 24, which engages or the locking of the gripper 19 with the gripper mushroom 20 by turning by 15 °. The rotary actuator 24 is supported on the bearing 22. A second actuator 25 attacks on the bearing 22. The second actuator 25 supports from the ceiling panel 17. This actuator 25 is used the orientation of the gripper 19 on the toothing of the Claw mushrooms 20.

The lifting rod 18 is surrounded by a bellows 26. This bellows 26 prevents contamination of the lifting rod and improves the contamination barrier between the work room 2 and the interior of the bell.

At the upper end of the lifting rod 18 is a carrier with two Carrier arms 27 attached. The support arms 27 are on one Support ring 28 attached, which surrounds the lifting rod 18 and this stores. The support arms 27 each lie on a console assembly 29 on and are by a bolt or one Screw 30 secured against moving. Any console assembly 29 is connected to a spindle nut 31.

In Fig. 2, two lifting spindles 32 are shown, which associated spindle nuts 31, the associated console assemblies 29 and thus the coupled via the support arms 27 Raise or lower the lifting rod 18. The lifting spindles 32 are driven by associated spindle drives 33.

At the upper end of the lifting rod 18 there is also a crane eye 34 attached. Another crane eye 35 is connected to the Bell 5 fixedly connected lifting device 6 attached.

Inside the gripper 19 is a surveillance camera 36 arranged. The leads to the camera 36 are through a channel 37 in the lifting rod 18 in the work space 2. The camera 36 is used to measure the inaccuracies in alignment between the bell 5 and the primary cover 7 or the gripper mushroom 20. This information is in control commands for the actuators 11 for shifting the cylindrical Recording 4 towards the center axis of the primary cover 7 used. The actuator 36 is also activated by means of the camera 36 25 to produce an equal orientation of Gripper 19 and gripper mushroom 20 controlled. Besides that subsequent coupling of the gripper 19 to the gripper mushroom 20 and visually monitors the locking.

First, the container 13 is in a (not shown Space) without special positioning requirements Rail vehicle posed. Then the gripper mushroom 20 on the primary cover 7 and the adapter ring 38 the end face of the container 13 pre-assembled. Then the Container 13 in the transport space 3 with the rail vehicle roughly positioned under the lock opening and with a unique Lifting process raised until the upper end face 14 of the adapter ring 38 on the lower end face 12 of the Recording 4 is present. This lifting is done, for example, by Limit switch controlled. Then the cylindrical Recording 4 with the bell 5 inserted therein with the help of Actuators 11 moved horizontally until the axis of the gripper 19 is exactly aligned with that of the gripper mushroom 20. This positioning process is monitored using the camera 36. Then the seal 15 between the end faces 12 and 14 inflated. Then the gripper 19 with With the help of the rotary actuator 25 in relation to the gripper mushroom given desired orientation rotated. Then the gripper 19 is lowered onto the gripper mushroom 20 and with With the help of the rotary actuator 24 for subsequent lifting Twisted 15 °. Then the primary cover 7 is lifted off and pulled up to the ceiling plate 17 of the bell 5. Now the bell 5 with the primary cover 7 can be taken out of the receptacle 4 can be highlighted, what with the help of a Crane eye 35 engaging cell crane is executed. Then is the inside of the transport and / or storage container from Working room 2 accessible. The container 13 can be loaded or be discharged.

In the event that partial or complete lifted primary cover 7 a link of the kinematisehen Chain of the lifting device 6 fails in such a way that the lifting rod 18 can no longer be moved electrically, so proceeded as follows.
