Abstract
The utility model relates to a door locking device of a personnel air lock on a containment, solving the technical problems that existing door locking devices have complex structures, poor machining and assembling process properties, big coefficient of adjusting difficulty and small locking forces and are difficult to maintain the reliability of locking for a long time. The door locking device comprises a slant base plate, a guide support and a bolt arm, wherein a slot and a rotating shaft are formed on the guide support; the bolt arm is connected with the guide support via the rotating shaft; the bolt arm is V-shaped; a rack pull rod is connected at the upper end of the bolt arm via a hinge pin; a roller is connected at the lower end of the bolt arm via a roller shaft. The door locking device can be widely applied to the personnel air lock.
Description
Technical field
The utility model relates to a kind of door lock assembly, particularly relates to the containment access lock door lock assembly for pressurized-water reactor nuclear power plant.
Background technology
Access lock is installed on Containment for PWR Nuclear Power Plant, and it is mainly at reactor cold-refueling and run duration, passes in and out the passage of containment to operation, safety check, maintenance personal, also can be used for transporting of some mini-plant, instrument and instrument etc. simultaneously.Door lock assembly is a vitals in access lock transmission mechanism, its effect is both at the two fan hermatic doors of guaranteeing to lock under nuclear power station nominal situation access lock, guarantee the integrality of containment structure, again can be at cold-refueling, between turn(a)round, unblank, remove locking function, by transmission mechanism, open two fan hermatic doors.
Yet although existing door lock assembly can meet instructions for use, complex structure, processing, assembly process process is poor, and adjusting gate, to process airtight tight lock status degree-of-difficulty factor large, and coupling mechanism force is little, is difficult to keep for a long time the reliability of locking.
Summary of the invention
The utility model is exactly in order to solve existing door lock assembly complex structure, processing, assembly process process is poor, adjustment difficulty coefficient is large, and coupling mechanism force is little, is difficult to keep for a long time the technical problem of the reliability of locking, provide a kind of simple in structure, part is few, and processing, assembly process process is good, and adjustment difficulty coefficient is little, coupling mechanism force is large, can keep for a long time the containment access lock door lock assembly of the reliability of locking.
The utility model provides a kind of containment access lock door lock assembly, comprises inclined-plane seat board, guide type shoe and bolt arm, and guide type shoe is provided with groove and rotating shaft, and bolt arm is connected with guide type shoe by rotating shaft; Bolt arm is v font, and the upper end of bolt arm is connected with tooth bar pull bar by bearing pin, and the lower end of bolt arm is connected with running roller by rolling axle.
Preferably, inclined-plane seat board is provided with adjustment screw.
The beneficial effects of the utility model are, simple in structure, part is few, and processing, assembly process process are good, and adjustment difficulty coefficient is little, and coupling mechanism force is large, can keep for a long time the reliability of locking; Utilize connecting rod running roller inclined plane force increasing principle, the reliable in function such as unlatching, locking, maintenance, realize easily, adjust simply, can reach the object requirement of access lock transmission mechanism to door lock completely.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is right view of the present utility model.
Symbol description in accompanying drawing:
1. guide type shoe; 2. tooth bar pull bar; 3. bolt arm; 4. rolling axle; 5. running roller; 6. inclined-plane seat board; 7. adjust screw; 8. bearing pin.
The specific embodiment
As Figure 1-3, guide type shoe 1 is arranged on inside and outside on-deck plate, on guide type shoe 1, rotating shaft is installed, and bolt arm 3 is arranged in the rotating shaft of guide type shoe 1.Guide type shoe 1 is provided with groove.
The shape of bolt arm 3 is v font, and its upper end is connected with tooth bar pull bar 2 by bearing pin 8.
Running roller 5 is arranged on the lower end of bolt arm 3 by rolling axle 4, inclined-plane seat board 6 is arranged on sealing every body, adjusts screw 7 and is arranged on inclined-plane seat board 6.
During use, when closing hermatic door need lock time, by the tooth bar pull bar 2 being meshed with sector gear in inside and outside two transmission cases, drive bolt arm 3 to turn round clockwise around the rotating shaft of guide type shoe 1, when bolt arm 3 enters in the groove of guide type shoe 1 and when running roller 5 touches the inclined-plane of inclined-plane seat board 6, bolt arm 3 compresses inclined-plane seat board 6 by running roller 5 to on-deck plate direction, thereby hermatic door is compacted to sealing state.
The large I of thrust regulates by the adjustment screw 7 on inclined-plane seat board 6.
When opening encapsulation door need be unblanked, by tooth bar pull bar 2, drive bolt arm 3 around the rotating shaft turning anticlockwise of guide type shoe 1, the running roller 5 on bolt arm 3 is thrown off with inclined-plane seat board 6, thereby hermatic door is unblanked.
