Definitions

  • the invention relates to a locking device for a protective door with a door leaf pivotably hinged to a door frame and with at least one drive shaft arranged in the door frame.
  • a protective door in a nuclear power plant can successfully withstand a break-in attempt and an unauthorized attempt to open it for a long time.
  • a locking device for a steel chamber door is known from DE-OS 26 06 222.
  • a drive shaft rotatably mounted in the door frame and designed as a bolt engages with a longitudinal groove in the door leaf in the locked state.
  • the drive shaft is formed over a part of its length forming the bolt in cross section in the form of a circular segment, so that the drive shaft lies completely within a groove in the door frame only in the unlocked state.
  • the effort to ensure play-free mounting of the drive shaft, which is simultaneously designed as a bolt is particularly high, in particular when using several drive shafts used at different points in the door frame. This can result in additional rework costs when installing on site.
  • the invention is therefore based on the object of creating a locking device for a protective door which is particularly simple to install and nevertheless ensures a high degree of security.
  • the drive shaft interacts via a coupling device with at least one bolt arranged in the door frame, the bolt being insertable into the door leaf, and the coupling device converting a rotary movement of the drive shaft into an axial displacement of the bolt.
  • cooperating drive shafts are arranged in all four sides of the door frame via bevel gears, the drive shafts having a common drive.
  • three of the four drive shafts interact with one bolt each. It is thereby achieved that for locking and unlocking the door leaf all drive shafts can be rotated simultaneously from one place and all bolts can be moved synchronously.
  • one of the drive shafts interacts with a locking device which can be unlocked either manually or by remote control.
  • the locking device comprises a perforated disk attached to the drive shaft and a displaceable bolt.
  • an electromagnet is advantageously provided which interacts with the bolt.
  • the bolt in turn in this case expediently interacts with a signaling or switch device for enabling the drive. This ensures that the drive is only put into operation when the door is unlocked.
  • a release device cooperating with one of the drive shafts which comprises a second signaling or switching device for unlocking a door drive.
  • the triggering device expediently has a perforated disk fastened to the drive shaft and a switching pin which can be brought into engagement therewith, the switching pin interacting with the second signaling or switching device. This ensures that each bolt is locked in the door frame after unlocking the door.
  • a lifting magnet is advantageously provided, which interacts with the switching pin.
  • the locking device expediently comprises a handwheel with a lock device which can be actuated by means of a key. With the lock device, the handwheel can be brought into engagement with one of the drive shafts and the locking device can be unlocked.
  • the advantages achieved by the invention consist in particular in that, by using a bolt which interacts with a drive shaft via a coupling device, it is possible to largely standardize such an assembly and its individual parts for protective doors of various sizes and barrier classes. Due to the arrangement of the individual parts of the locking device in the door frame, a very precise adjustment of the bolt is already possible in the workshop, so that bearing play and rework at the place of use of the protective door are avoided.
  • the protective door 1 shown in FIG. 1 in the open position comprises a door leaf 2 and a door frame 3 which surrounds the door leaf 2 on all sides in the closed state.
  • the door leaf 2 is hinged to the door frame 3 with hinges 4, only one of which is visible.
  • the door frame 3 is fastened with an anchor 5 in a wall 6.
  • a bolt-shaped bolt 8 can be seen in the unlocked state.
  • Another bolt-shaped bolt 9 is arranged in the door sill 10 of the door frame 3.
  • the bolt 9 is inserted into a hole or pocket 11 on the underside of the door panel 2.
  • the bolt 8 is then inserted into the door leaf 2.
  • a blind frame 12 and a cover frame 13 are provided for covering the anchoring 5 and further fastening and locking means - as shown in FIG. 2, so that undesired access to the fastening and locking means is reliably avoided.
  • a gripper 15 is additionally attached to the side part 14 of the door frame 3, to which the door leaf 2 is articulated, which engages in the door leaf 2 when the protective door 1 is closed.
  • FIG. 2 schematically shows a locking device 20 with four drive shafts 22, 24, 26 and 28.
  • the drive shafts 22 and 26 are rotatably mounted and concealed in the two door posts - corresponding to the side parts 7 and 14 of the door frame 3 according to FIG. 1.
  • the drive shaft 24 is rotatably and concealed in the door sill 10.
  • the drive shaft 28 is arranged in a corresponding manner in the lintel.
  • the drive shafts 22, 24, 26 and 28 interact via bevel gears 30 and are driven by a common drive 32.
  • the drive shafts 22, 24 and 28 also each interact via a coupling device 33, 38 and 42 with a bolt-shaped bolt 8, 9 and 46, respectively.
  • the coupling device 33 comprises a bevel gear 34 which is fastened on the drive shaft 22 and which interacts with a worm gear 35 for displacing the bolt 8. With the coupling device 33, a rotary movement of the drive shaft 22 is thus converted into an axial displacement of the bolt 8. An additional force effect on the bolt 8 is achieved with a spring 36.
  • the coupling device 38 is designed in the form of a transmission and comprises a first gear 37 fastened to the drive shaft 24 and a second gear 39 which is coupled to the bolt 9 via a first rod 40 and a further gear 41.
  • the gears 39 and 41 and the rod 40 form a coupling part, with which, at a predetermined length of the rod 40, a specific location of the bolt 9 is fixed in the door sill 10 of the door frame 3.
  • each of the bolts 8, 9 and 46 is inserted into the door leaf 2.
  • the drive shafts 22, 24, 26 and 28 are blocked by means of a locking device 50.
  • the locking device 50 comprises a perforated disk 51 fastened on the drive shaft 24 and a bolt 52 which is pushed into and out of a hole 54 of the perforated slide 51 with the aid of an electromagnet 53.
  • the bolt 52 has a spring 56 in the area between the electromagnet 53 and an end piece 55.
  • the electromagnet 53 is operated, for example, by remote control, the bolt 52 opening the hole 54 in the perforated disk 51.
  • the bolt 52 actuates with the end piece 55 a signaling or switching device 57 for unlocking the drive 32. This position of the end piece 55 of the bolt 52 is shown in broken lines.
  • a door drive (not shown) for opening the protective door 1 is actuated by means of a trigger device 60.
  • the triggering device 60 comprises a perforated disk 61 fastened on the drive shaft 26 and a switching pin 62 which actuates a second signaling and switching device 63.
  • the switching pin 62 is seated such that the door drive (not shown) is switched off.
  • the switching pin 62 In the unlocked state, the switching pin 62 is pressed by means of a spring 64 into a hole 65 in the perforated disk 61. At the same time, a switch or detector 67 for switching off the drive 32 is actuated with a trigger 66 fastened on the perforated disk 61. In addition, the signaling or switching device 63 is actuated with an end piece 68 of the switching pin 62 to switch on the door drive. A lever 69 is fastened to the switching bolt 62 and actuates two lifting magnets 70, 71 in the unlocked state, as indicated by the broken line of the lever 69.
  • the solenoids 70 and 71 are actuated, so that the switching pin 62 releases the perforated disk 61 and the spring 64 is tensioned.
  • the trigger 66 is used to actuate a further switch or detector 72, with which the shutdown or interruption of the drive 32 is canceled.
  • an operating lever 75 is provided which interacts with the drive shaft 26 via a gear 76.
  • the operating lever 75 is unlocked against the force of a spring 77 and a rotary movement is transmitted to the drive shaft 26 via the bevel gears 78 and 79 by means of a lever effect.
  • the protective door 1 can also be unlocked and opened manually with a handwheel 80.
  • a mechanical lock 82 is unlocked with a key 81, a lock slide 83 engaging a pinion arrangement 85 which interacts with the handwheel 80 and a pinion 86 via a clutch lever 84.
  • the pinion 86 cooperates with a gear 87 fastened on the drive shaft 22.
  • the handwheel 80 is in engagement with the drive shaft 22, so that the protective door 1 is unlocked and the door leaf 2 can be pulled open by hand.
  • the locking device 20 according to the invention can be assembled with little effort due to its simple structure. All individual parts, such as the coupling parts already mentioned can be provided in the form of modules in different dimensions and can thus be used in differently designed protective doors 1.
  • the motorized bolts 8, 9 and 46 ensure a high degree of accuracy and cause little or no locking noise.
