The interlocking clutch device comprises a cam, a ratchet and an interlocking pawl, wherein the interlocking pawl is arranged between the cam and the ratchet and the interlocking pawl is connected with a pawl supporting shaft; the interlocking pawl is provided with a pawl rod, an unlocking pin is arranged on one side of the pawl rod and a limiting block is arranged on the other side of the pawl rod. The interlocking clutch device of the containment personnel airlock transmission mechanism can be widely used on personnel airlocks.
Description
Technical field
The present invention relates to a kind of interlocking arrangement of clutch, particularly relate to the containment access lock transmission mechanism interlocking arrangement of clutch for pressurized-water reactor nuclear power plant.
Background technology
Access lock is installed on Containment for PWR Nuclear Power Plant, it is mainly at reactor cold-refueling and run duration, operating personnel, security staff, maintenance personal pass in and out the passage of containment, also can be used for transporting of some mini-plant, instrument and instrument etc. simultaneously.Interlocking arrangement of clutch is a core component of access lock transmission mechanism, its effect is to guarantee that under nuclear power station nominal situation, two fan hermatic doors of access lock can not be opened simultaneously, guarantee the integrality of containment structure, again can be at cold-refueling, between turn(a)round, remove interlocking, open two fan hermatic doors simultaneously.
Yet, with reference to notification number, be that " CN202299786U ", name are called the Chinese patent of " interlocking device of personnel airlock ", although existing interlocking arrangement of clutch can meet instructions for use, but complex structure, processing, assembly process process is poor, and number of spare parts is many, adjustment difficulty coefficient is large, site assembly need to manufacture, precision is low, after releasing interlocking, is difficult to keep for a long time, recovers interlocking adjustment programme complicated.
Summary of the invention
The present invention is exactly in order to solve existing interlocking arrangement of clutch complex structure, processing, assembly process process is poor, and number of spare parts is many, and adjustment difficulty coefficient is large, site assembly need to manufacture, precision is low, after removing interlocking, be difficult to keep for a long time, recover the technical problem of interlocking adjustment programme complexity, provide a kind of simple in structure, part is few, processing, assembly process process is good, and the reliable in function such as interlocking, releasing, maintenance easily realize, the simple containment access lock of program transmission mechanism interlocking arrangement of clutch.
The invention provides a kind of containment access lock transmission mechanism interlocking arrangement of clutch, comprise cam, ratchet and interlocking ratchet, interlocking ratchet is between cam and ratchet, and interlocking ratchet is connected with ratchet back shaft; Interlocking ratchet is provided with pawl bar, and a side of pawl bar is provided with latch, and opposite side is provided with limited block.
Preferably, latch comprises outer cylinder body, is provided with bearing pin in outer cylinder body, and the upper end of bearing pin is connected with knurling handle, between bearing pin and the roof of outer cylinder body, is provided with spring.
The invention has the beneficial effects as follows, simple in structure, part is few, and processing, assembly process process is good, and the reliable in function such as interlocking, releasing, maintenance easily realize, program is simple; Adopt lever principle, by power transmission shaft, drive distal seal door power shaft, near-end click from, cooperation use, the open and close of control far-end door, reach the object of interlocking, guarantee that, when opening near-end door, far-end door can not be opened.Or open in the process of far-end door, near-end door is in closed condition.

Symbol description in accompanying drawing:
1. cam; 2. latch; Interlocking ratchet; 4. ratchet; 5. ratchet back shaft; 6. limited block; 7. transmission mechanism gear wheel; 8. knurling handle; 9. outer cylinder body; 10. spring; 11. bearing pins.
The specific embodiment
As shown in Figure 1, the present invention includes cam 1, cam 1 is arranged on the gear shaft of (outward) portion transmission case in transmission mechanism, and cam 1 is can be under the drive of gear shaft clockwise or be rotated counterclockwise certain angle.The ratchet back shaft 5 that plays support fixation is fixedly mounted on the transmission case cover plate of transmission mechanism, and interlocking ratchet 3 is connected with ratchet back shaft 5.
As shown in Figure 5, latch 2 comprises outer cylinder body 9, is provided with bearing pin 11 in outer cylinder body 9, and knurling handle 8 is connected with the upper end of bearing pin 11, between bearing pin 11 and outer cylinder body 9 roofs, is provided with spring 10.
As shown in Figure 2, when near-end door is closed, cam 1 is rotated counterclockwise, the height point of cam 1 contacts gradually with the end of pawl bar of interlocking ratchet 3, stirs interlocking ratchet 3 and to clockwise direction, rotates centered by ratchet back shaft 5, till the pawl bar that always turns to interlocking ratchet 3 contacts with limited block 6, the claw of ratchet 3 of making to interlock departs from ratchet 4 completely, at this moment, ratchet 4 can rotate arbitrarily, and far-end door is just free to rotate.
As shown in Figure 3, when near-end door is opened, cam 1 is separated gradually with the end of the pawl bar of interlocking ratchet 3, the claw of interlocking ratchet 3 under itself Action of Gravity Field with ratchet 4 engagements, at this moment, ratchet 4 can not rotate to clockwise direction, can not be to far-end Men Kaimen direction rotation, can only, to counterclockwise rotating, be exactly that far-end door dallies to the direction of closing the door, thereby reach the object of interlocking.
When two ends door is during all in closed condition, the interlocking ratchet 3 at two ends and ratchet 4, all in the position of leaving as shown in Figure 2, can be opened any one door.
When near-end door is opened, in the time of need to removing the interlocking of far-end door, interlocking ratchet 3 is in position as shown in Figure 3, latch 2 is in position as shown in Figure 4, the knurling handle 8 of mentioning latch 2 turns an angle, pin on knurling handle 8 is aimed in the locating hole on outer cylinder body 9, bearing pin 11 extends under the effect of spring 10, on bearing pin 11, circular arc place contacts with the pawl bar of interlocking ratchet 3, the pawl bar of stirring interlocking ratchet 3 rotates to clockwise direction, the claw of interlocking ratchet 3 is separated with ratchet 4, ratchet 4 and interlocking ratchet 3 are in the released state shown in Fig. 2, remove the interlocking with far-end door.
When needs recover interlocking, the knurling handle 8 of mentioning latch 2 rotates a little, pin on knurling handle 8 leaves the locating hole on outer cylinder body 9, bearing pin 11 just leaves the pawl bar of interlocking ratchet 3, the position of latch 2 in Fig. 1, the claw of interlocking ratchet 3 automatically meshes with ratchet 4 under Action of Gravity Field own, and interlock recovers.
