Abstract
The invention provides a door lock device of a personnel air lock of a containment, and the door lock device is used for solving the technical problems that an existing door lock device of the personnel air lock is complex in structure, small in locking force and poor in reliability. The door lock device is provided with a support which is provided with a rotary shaft, and the rotary shaft is provided with a roller base which can rotate around the rotary shaft. The door lock device of the personnel air lock of the containment is further provided with a rack connecting rod. One end of the roller base is connected with the rack connecting rod, and the rack connecting rod can rotate relative to the roller base. A roller shaft is arranged at the other end of the roller base. The door lock device of the personnel air lock of the containment is further provided with an eccentric cam base which is provided with an eccentric cam surface. The door lock device provided by the invention can be widely applied to the field of locking devices.
Description
Technical field
The present invention relates to a kind of locking device, especially relate to a kind of containment access lock door lock assembly.
Background technology
We know, Containment for PWR Nuclear Power Plant is provided with access lock, and it is at reactor cold-refueling and run duration, and operation, safety check, maintenance personal pass in and out the passage of containment, also can be used for transporting of the mini-plants such as some instrument and instrument simultaneously.
Door lock assembly is a vitals in access lock transmission mechanism, they can either be 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, open two fan hermatic doors by transmission mechanism.
Access lock transmission mechanism all adopts door lock assembly to lock or release, although but existing door lock assembly can meet instructions for use substantially, but complex structure, processing, assembly process process is poor, adjust gate large in airtight locking state degree-of-difficulty factor, coupling mechanism force is little, is difficult to keep for a long time the reliability of locking.
Summary of the invention
The present invention be directed to the technical problem of the little and poor reliability of assigned personnel's gate door lock assembly complex structure, coupling mechanism force, provide a kind of simple in structure, coupling mechanism force large and the containment access lock door lock assembly of good reliability.
For this reason, the present invention is provided with bearing, and bearing is provided with rotating shaft, and rotating shaft is provided with running roller seat, and running roller seat can rotate around the shaft; Containment access lock door lock assembly is also provided with tooth bar connecting rod; Running roller seat is provided with two ends, and one end of running roller seat is connected with tooth bar connecting rod, between tooth bar connecting rod and running roller seat, can relatively rotate; The other end of running roller seat is provided with rolling axle; Containment access lock door lock assembly is also provided with eccentric cam seat, and eccentric cam seat is provided with eccentric cam face.
The preferred technical scheme of the present invention is on rolling axle, to be arranged with spacer.
The further preferred technical scheme of the present invention is on running roller seat, to be also provided with self-aligning roller bearing.
The further preferred technical scheme of the present invention is on eccentric cam seat, to be also provided with adjustment screw.
Access lock door lock assembly used in the present invention, adopts adjustable eccentric cam reinforcement principle, principle uniqueness; Turn round around bearing by tooth bar pull bar driven roller wheel seat, by self-aligning roller bearing, eccentric cam seat is compressed or unclamps and realize the locking of hermatic door and unblank to access lock door-plate direction, simple in structure, move reliable, coupling mechanism force is large, reliable lastingly, unblanks convenient and swift.

The specific embodiment
Now, the specific embodiment that present invention will be described in detail with reference to the accompanying.
As shown in Figure 1 to Figure 3, the present invention is provided with bearing 1, and bearing 1 is provided with rotating shaft 5, in rotating shaft 5, is provided with running roller seat 6 by bearing pin 4, and running roller seat 6 can 5 rotate around the shaft.The present invention is also provided with tooth bar connecting rod 2, and tooth bar connecting rod 2 is connected with one end of running roller seat 6, between itself and running roller seat 6, also can relatively rotate.In the time that tooth bar connecting rod 2 is driven, coupled running roller seat 6 can do clockwise or rotate counterclockwise around bearing 1.
The other end of running roller seat 6 is provided with rolling axle 7, is arranged with spacer 9 on rolling axle 7.The present invention is also provided with self-aligning roller bearing 8, and self-aligning roller bearing 8 is arranged on running roller seat 6 by rolling axle 7 and spacer 9.
The present invention is also provided with eccentric cam seat 3, and eccentric cam seat 3 is located on the door body of access lock, and eccentric cam seat 3 is provided with eccentric cam face 11.In the time that the self-aligning roller bearing 8 on running roller seat 6 gradually contacts with eccentric cam face 11, eccentric cam seat 3 compresses to door-plate direction.On eccentric cam seat 3, be also provided with and adjust screw 10, it can be used for the size of thrust between eccentric adjustment cam chair 3 and access lock door-plate.When adjusting, screw 10 is fashionable to eccentric cam seat 3 inward turnings, and thrust diminishes; In the time adjusting screw 10 to the outer back-out of eccentric cam seat 3, it is large that thrust becomes.
For cost-saving, self-aligning roller bearing 8 of the present invention and spacer 9 also can not arrange, and directly make rolling axle 7 contact with eccentric cam face 11 and complete gradually substrate hold-down function.
Below specific works process of the present invention is described in detail.
In the time closing access lock and need sealing locking, under tooth bar pull bar 2 power-actuated effect outside, drive running roller seat 6 to turn clockwise around bearing 1, in the time that the self-aligning roller bearing 8 on running roller seat 6 contacts gradually with the eccentric cam face 11 of eccentric cam seat 3, running roller seat 6 compresses eccentric cam seat 3 by self-aligning roller bearing 8 to access lock door-plate direction, thereby hermatic door is compacted to seal request.The large I of thrust regulates by the adjustment screw 10 on eccentric cam seat 3.
In the time that opening encapsulation door need to be unblanked,, the self-aligning roller bearing 8 on running roller seat 6 is thrown off gradually with the eccentric cam face 11 of eccentric cam seat 3, thereby access lock is unblanked around bearing 1 turning anticlockwise by tooth bar pull bar 2 driven roller wheel seats 6.
Only as described above; be only specific embodiments of the invention, when not limiting scope of the invention process with this, therefore the displacement of its equivalent assemblies; or equivalent variations and the modification done according to scope of patent protection of the present invention, all should still belong to the category that the claims in the present invention book is contained.
