    Apparatus for manipulating a quantity of radioactive material between a stored position and a use position is provided with a coupling apparatus for separably connecting cable controls to a storage unit at the storage position, having a coupler component fixed to the storage unit and a separable component (40,42) fitted to the control cable. The latter fits into an aperture in the fixed component (20,22,32,34,38), where it can be locked against removal. The fixed component (20,22,32,34,38) locks the radioactive material leader for safe storage when the control cable is disconnected. Connection of the control cable permits the operator to release the lock on the leader. The act of releasing that lock establishes an interlock which prevents removal of the separable component (40,42) from the fixed component (20,22,32,34,38).

The radiographic device consists of a storage unit 1 with a through channel, a guide tube 2 in which the flexible actuator 3 is located. At the end of the flexible actuator a capsule 4 with a radioactive substance is attached. At the end of the pipe on the storage unit there is a detachable connection 5 (Fig. 2- 7). The first detachable element consists of the mounting plate 6, the base unit 7 with the first and second slots 8 and 9, respectively, formed therein, the first and second sliding blocks 10 and 11 of the latch 12, the key 13, in which the tubular hole 14 is formed. and, optionally, lock 15, installed in a keyhole. The second detachable member consists of a tubular body 16 for telescopic insertion. a tubular bore 14, and a tubular slider 17 located in the tubular body (FIG. 3). The blocking element is assembled on the mounting plate 6, and when used, the mounting plate 6 is attached to the storage unit, an example is node 1 (Fig. 1). The base unit 7 has a main opening 18, which is adjacent to the through channel when the first element is attached to the storage unit. The main hole extends from the bottom wall of the first groove 8. Next to the main hole 18 in this lower wall is a blind hole 19 for installing a spring 20 714, a compression and a circular part 21 of the latch 12 ,, The front part 22 of the latch is flattened (Fig. 7). The first sliding block 10 is rectangular, slidably inserted into the first groove 8, and can be displaced across the main opening 18. The finger 23, located at one end of the first sliding block 10, projects in the direction of the mounting plate 6. At the bottom of the first the slider block has a groove 24 for locking. The slot 25 in the first sliding block 10 ends at one end with a round hole 26, which exactly coincides with the main hole 18 in the base block when the sliding block is shifted to one of its operating positions. In this position, the finger 23 comes into contact with the part 27 of the wall of the base unit 7. The front end of the round latch part 21 enters the shallow recess 28 in the rear wall 29 of the first sliding block 10 when the sliding block is offset in slot 8 into the second operating position ( a shallow recess 28 is shown by the dotted line in Fig. 4 and in cross section in Fig. 6). The flattened front portion 22 of the latch 8 extends forward through the slit 25 into the second slidable block 11. When the first slidable block 10 is locked by inserting the latch 12 into the recess 28, the hole 26 does not coincide with the main hole 18 in the base block 7, and the slit 25 superimposed on main port 18 (Figs. 2 and 9). The other opening 30 of the sliding block 10 is on the same axis with the latch 31 of the lock 15 when the sliding block 10 is locked, which allows the system owner to lock the first sliding block, thereby preventing the intact use of the system containing this connecting device. The lock has a second part 32 larger than the bolt diameter. The second sliding block 11 is made rectangular with the possibility of sliding in the second groove 9, is superimposed on the first sliding block 10 and has the ability to move across the main hole 18 in the base block. 7. For convenience, the second gliding block 11 moves across the direction of movement of the first gliding block 10, whereby each slider
    the unit moves in its direction, minimizing the potential for a failure in the operation of the device (Fig. 2). A pair of springs 33 is placed at one end in recesses 34. at one end of the second sliding block and rests its second ends on an overhanging shelf 35 protruding from the clip 13 towards the base block 7. These springs push the second sliding block down (FIG. . four)
    In the second sliding block 11, a passage opening 36 is made, having a diameter that is the same with a tubular opening 14, and a second opening 37 adjacent to the passage opening 36 so that the areas of these holes partially overlap each other. The second opening 37 has a smaller diameter than the through opening, the diameter from the end 38 of the second sliding block. The second hole is recessed into the opposite Iorez 39 so that from this end the second hole 37 has essentially the same diameter with the hole 36, creating an arcuate recess 40 in the second hole.
    The first locking pin 41 in the second slipping unit, located below the through hole, projects in the direction of the first slipping unit -10 and can enter the groove 24 when the first slipping unit is in the locked position. The second locking finger 42 is above the second aperture 37 and passes over the upper edge (Fig. 2) of the first sliding block 10.
    In the disconnected state, when the tubular body 16 is pulled out (Fig. 2), the springs 33 push the second sliding block down to a position in which the second locking pin 42 lies on the first one. SLIDING BLOCK. In this position, the arcuate recess 40 is visible through the tubular hole 14 (Fig. 2).
    The tubular body 16 of the second element has an annular groove 43 near its outer end 44 (FIG. 3), the flange 45 creates a short diameter passage smaller than the diameter of the passage of the main body of the tubular body 16. The tubular slider 17 has an enlarged portion 46 (FIG. 3), whose outer diameter is slightly
    smaller than the inner diameter of the tubular body 16, but larger than the inner diameter of the flange 45, so that the slider 17 can enter through the outer end 44 into the tubular body 16, but cannot enter from it through the end 47.
    The inner end 48 of the slider 17 has an external thread for attachment to the guide tube 2.
    The flexible actuator 3 can pass through the tubular slider 17, ending at the end with a conventional cable connection. This connecting hour has a tapered flange 50, the diameter of which exceeds the diameter of the internal passage of the slide 17, so that the connecting part 49 cannot be pulled out through the internal passage. The connecting part. 49, however, may be stretched out of the tubular body 16 as much as is necessary for conveniently connecting to the stem connected to the capsule.
    FIG. 8 shows the second section of the actuator 3 of the rod, including the connecting element 51. The method of connection is shown in dotted line.
    In the proposed device, any connecting element can be used.
    Between the connecting member 51 and the rod, a locking section 52 is provided during storage of a smaller diameter for engagement in the slot 25 when the first sliding unit is in the locked position. The leash section (FIG. 8) from the receiving part to the locking section during storage 52 can pass through the opening 26 in the first sliding unit 10, but only the section 52 can pass into the slot 25.
    The distance from the locking section 52 during storage to the receiving part of the connector is such that when the locking section 52 is hooked into the slot 25 during storage, the receiving part of the connector protrudes from the tubular hole 14 and is rigidly fixed in this position, so that part of the connector 49 can be connected to it (Fig. 9). The first sliding unit is in the locked position, and the passage opening 26 is not on the same axis with the main opening 18. The latch 31 of the lock is shown meshed with the opening 30. The length of the drive rod 3 is such that when the storage section 52 is locked in slot 25, a capsule 4 of radioactive material attached to a rod (not shown will be located in the secured storage position in the storage unit. 1 (Fig. 1).
    If the second sliding block 11 is shifted to the left (Fig. 2), the first locking pin 41 will fit into the groove 24 in the first sliding block 10, the arcuate recess 40 is pulled out of the tubular bore 14 and the tubular body 16 of the detachable element can be drawn through the tubular a hole in the passage hole 36 where the outer end 44 contacts the opposite end of the flattened front part 22 of the latch 12 and pushes the circular part 21 from the shallow recess 28 in the rear wall 29 of the first sliding block 10. When the pushing force is removed from the second slip Block 11, springs 33 return it to the position shown in FIG. 2 and 10, where the arcuate recess 40 engages with the annular groove 43 in the tubular body 16, thereby connecting the tubular body 16 to the first detachable connection member.
    FIG. 11, the latch 12 is released from the engagement with the first sliding block 10, which is now unlocked and placed in the working position, having the hole 26 on the same axis as the main hole 18. The locking pin 23 is moved to the wall portion 27 of the base unit 7. In this working position the first slip block 10, the groove 24 does not coincide with the first locking pin 41 on the second sliding block 11, and the first sliding block 10 does not allow the second sliding block 11 to release the tubular body 16 until the passage opening 26 coincides with the main hole 18. Flexible drive 5 t per can be conducted through the connecting device and the system can operate (FIG. 1).
    When the flexible actuator 5 (non-shown) is in the opening 26, the first sliding block 10 cannot be moved to the locked position.
    then, the diameter of the drive is larger than the width of the slot 25. During the reverse operation, the flexible drive 5 returns the radioactive material to the storage position and at the same time introduces the locking section during storage 52 into the hole 26.
    The first sliding unit 10 is transferred from its working position (Fig. 1 to the locked position (Fig. 9)), locking the rod located in the storage unit 1. The groove 24 now coincides with the first locking finger 41 of the second sliding unit 11, which
    moves (to the left in FIG. 2) and releases the tubular body 16 of the releasable member from engagement with the arcuate recess 40.
    Tubular body 16 can now. withdraw the cable connecting device from the second plug-in element, pull out the cable connecting device, and separate the parts 49 and 52.
    The latch 12 enters the recess 28 for locking the first sliding unit 10 into the storage position, and the lock 32 (if present) can be activated by inserting the latch 31 into the opening 30 to prevent unauthorized use of the system.
    The tubular body 16 must be pulled back towards the fitting in order to release the connecting part 49. After connecting the cable connector, the outer part of the tubular body 16 is locked in the second detachable connection element (Fig. 10). The outer part of the tubular body 16 is inserted using the slider 17 into the tubular hole 14.
    When using the system, the slider 17 moves in the tubular body 16 and after use it is desirable to return the radioactive material to the storage position (Fig. 1), the cable connector will come into contact with the increased section 46 of the slider 17 in a position so close to the first sliding block 10, that the locking section 52 during storage will not be located in the circular opening 26. Therefore, in order to securely place the radioactive material in the storage position and separate the components of the coupling device and
    cable connector, you must remove the tubular slider 17 from the body 16.
    In order to minimize such an opportunity, the connector component is preferably provided with a third sliding block 53, which interacts with the lip 54 on the tubular slider 17 as the second sliding block 11 interacts with the annular groove 43 (Fig. 3, 12 and 13).
    The housings 55 and 56 attached to the outer tubular body 16 (Fig. 3) provide a guide 57 for the third sliding block 53, along which the third sliding. the block can be moved across the axis of the tubular orifice. Like the second sliding block 11, the third sliding block has a pair of frequency-overlapping holes 58 and 59, the larger of the KOTopijpc hole 58, is large enough to pass the edge 54, which cannot pass through the smaller hole.59. A pair of springs 60 pushes the third sliding unit 53 down so that the smaller opening 59 tends to be in the passage to the outer. there is a tubular body 16 (Fig. 13). The third slider unit 53 moves upward (FIG. 12) to allow the rim 54 to move toward the flange 45 at the end 47 of the tubular body 16. After releasing the third slider unit then moves so that the smaller hole 59 turns out to be behind the rim 54, locking inner tubular slider 17 in fully extended position. In the event that a connection is required, this valve opens and the relative positions of the tubular body 16 and the slider 17 (Fig. 3) are restored.
    When the guide tube 2 is attached, the nozzle prevents the slide 17 from escaping through the outer end 44 of the tubular body 16 (Fig. 3
    According to the second variant of the device, the fixed element consists of the mounting plate 62, the block 63 of the base with the first groove 64, with the one located. there is a first blocking element in the form of a slider 65, a latch 66, a cam ring 67, a cover 68 in which a tubular hole 69 is made and, if desired, a lock 70 installed in block 71. The second element of the detachable connection consists of a tubular body 72 for a telescopic insertion into a tubular opening 69 (shown in cross section, Figs. 20 and 21). The fastened element is assembled on the mounting plate 62 by means of bolts 73 (only one of them is shown in Fig. 17) and, in use, the plate 62 is attached to the storage unit 1 (Fig. 1).
    Block. 63 of the base has a main opening 74, which coincides with the through channel when the fastened element is attached to the storage unit. The main hole extends from the bottom wall 75 of the groove 64. Next to the main hole 74, there is a non-through hole 76 in which a compression spring 77 and a circular one are inserted. ; the base 78 of the latch 66. The front part 79 of the latch 66 is flattened (FIG. 17). The slider 65 is a rectangular sliding block slidably inserted into the groove 64 so that it can move across the main hole 74. The slit 80 in the slider 65 ends at one end with a circular passage 81 arranged to coincide with the main hole 74 in the warp block when the glide block is moved to one of its operating positions.
    In this position, the latch 66 is displaced into its opening 76, compressing the spring 77. The shallow recess 82 in the rear wall 83 of the slider 65 (FIG. 20) receives the front end of the round latch base 78 when the slider moves along the groove 64 to the second of its operating positions. The flattened front portion 79 of the latch then extends forward through the slit 80 in the space between the slider 65 and the collet block 68. When the slider 65 is locked by the latch 66 in the recess 82, the circular passage 81 does not coincide with the main hole 74 in the base block 63 and the slit 80 overlaps the main hole 74 (Fig. 14).
    The cam ring 67 controls the slider 65 in the groove 64 moving across the main opening 74 in the base unit 63. The cam ring is a tubular body having a rolling track 84 located not in the center, along which the rounded ends 85 and 86 of the sliding block 65 move along the diametrically opposite contact line. Behind the track 84, closer to the base unit 63, the cam ring has a protrusion 87 with a centrally located round hole 88 that extends into the front round part 89 of the base unit. The finger 90 in the hole 191 in the front circular portion 89 holds the flange 87 on the base unit. The notch 92 in the flange 87 is designed for mounting the cam ring on the base unit during the assembly of the fixed component. The surface of the outer circumference 93 of the cam ring is knurled to facilitate manual rotation of the cam ring on the circular surface of the front circular part 89 of the base unit 63. When the cam ring rotates on the base block, the eccentric cam track 84 moves the slider 65 along groove 64, if the latch 66 is not in the recess 82. The slider has a number of grooves 94 on the longitudinal surface 95, opposite the upper surface 96 of the groove 64 (Figures 16 and 17). The installation screw 97 is located in the threaded hole 98 and is provided with a spring-loaded ball 99, which fits into one of the grooves 94 in each of the three positions of the slider in the groove 64. Each of these positions corresponds to one of the inscriptions Connection, Locking and Working Position, which are with an interval of 90 at the front end of the cam ring. Krishka 68 has a cut segment, forming a flat surface 100, on. which only one of these labels is visible, depending on the angular position of the cam ring 67 relative to the cam block (Fig. 14). The locking hole 101 in the cam ring on its outer circumference is designed to insert the lock valve 102 of the lock 70 when the cam ring 67 is turned so that the gate and the valve are on the same axis. In this position, over the flat surface 100 of the lid 68, the inscription Locking is visible. The slider 65 has a locking protrusion 103 for engaging the tubular body 72 of the releasable member in the arcuate recess 104, which can be inserted into and out of the annular groove 105 as the slider moves along the groove 64, the casing shaft or releases the annular groove 105 of the tubular body (Fig. 19). The front part 79 of the latch passes through the slit 80. When the round latch base 78 enters the recess 82 of the rear wall of the slider 65, this corresponds to the Connection position, in which the locking protrusion 103 is retracted to the side, holding the arcuate recess 104 outside the annular groove 105. The end 106 of the tubular the body 72, in which the annular groove 105 is located, can be inserted into the tubular hole 69, the latch front part 79, and the circular base 78 extends out of the recess 82, releasing the slider 65 so that it can be moved along the groove to Work its position by turning the cam ring 67 clockwise about half a turn. . The cam ring has three positions, (Figs. 14 and 18), which are respectively the positions Connection, Locking and Working position. With the locking position, the cam ring is rotated approximately a quarter of a turn clockwise (Figs. 17 and 18) and the slider 65 is only partially slit in groove 64 so that the bore 81 does not yet coincide with the main hole 74, and the locking section during storage of the connector remains in the slot 80. The locking plug 107 (Fig. 23) is used to release the latch 66 so as to set the cam ring to the Locking position, the front end of this plug has an end 108 that can push the front part 79 of the latch, and an annular a groove 109 of a larger diameter than the annular groove 105 in the tubular body 72, into which the arcuate groove 104 of the locking protrusion 103 is inserted, but due to the size of its diameter it does not give a slider
    65 move to the working position where the passage opening 81 would coincide with the main opening. In this position, a lock 70 can be used to insert its valve 102 into the locking hole 101. The locking plug 107 remains in the tubular hole 69 of the fixed element, locking the end of the connector in the hole 110. In this state, the storage unit 1 containing radioactive material can be transported or stored without a drive attached to it
    The tubular body 72 of the releasable member has an annular recess 104 near its first end 106 (FIGS. 14, 20, and 21). The annular protrusion 111 creates a short passage 112 of smaller diameter than the passage through the main body of the tubular body 72. The second end 113 of the tubular body 72 has an outer thread for attaching a guide tube, such as the guide tube 12 (Fig. 1). The drive cable 3 may pass through a short passage 112, ending with a plug-in portion of a typical cable connection. This part of the joint has a tapered part 114, the larger diameter of which is larger than the diameter of the short passage 112 so that part of the joint cannot be taken out through the short passage.
    The inserted part of the connection can, however, be pulled out of the tubular body 72 so that it is convenient to connect the cable connector tube. Distance from far; the end 106 to the protrusion 111 is such that the tubular body 72 cannot be inserted into the tubular-hole 69 far enough to release the slider 65 from the latch 66, unless the connector parts before it are connected.
    In order to change the locking position to the working position, first of all, it is necessary to open the lock 70, turn the cam ring 67 to the Connection position and remove the locking plug. This allows the latch 66 to lock the slider 65, keeping j in such a way that the receiving part of the connector is locked in the storage position, where the insertion part can be attached to it, after which the tubular body 72 can be inserted into the tubular opening 69 to press the front part 79 of the latch, and cam ring 67 can be rotated to Work Position. In this position, the slider 65 is shifted along the groove 64 to a position in which the through hole 81 co. Fits with the main hole 74, and the connector can be passed through the slider using the flex
    drive 3. (
    The diameter of the annular groove 104 is smaller than the diameter of the annular groove 109 of the locking plug so much that it allows this additional movement of the slider.
