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 the transport 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 guarantee that two fan hermatic doors of access lock under nuclear power station nominal situation can not be opened simultaneously, ensure the integrality of containment structure, again can at cold-refueling, between turn(a)round, remove interlocking, open two fan hermatic doors simultaneously.
But, with reference to notification number be " CN202299786U ", name is 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 parts is many, adjustment difficulty coefficient is large, site assembly needs manufacture, precision is low, are difficult to keep for a long time after removing interlocking, recover interlocking adjustment programme complexity.
Summary of the invention
The present invention is exactly to solve existing interlocking arrangement of clutch complex structure, processing, assembly process process is poor, and number of parts is many, and adjustment difficulty coefficient is large, site assembly needs manufacture, precision is low, be difficult to keep for a long time after removing interlocking, recover the technical problem of interlocking adjustment programme complexity, provide a kind of structure simple, part is few, processing, assembly process process is good, the reliable in function such as interlocking, releasings, maintenance, and easily realization, program simple containment access lock transmission mechanism are interlocked 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 the side of pawl bar is provided with latch, and opposite side is provided with limited block; 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, is provided with spring between bearing pin and the roof of outer cylinder body.
The invention has the beneficial effects as follows, structure is simple, and part is few, and processing, assembly process process are good, the reliable in function such as interlocking, releasings, maintenance, and easy realization, program are simple; Adopt lever principle, drive distal seal door power shaft by power transmission shaft, near-end click from, cooperation use, control the open and close of far-end door, reaching the object of interlocking, guaranteeing 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.

Detailed description of the invention
As shown in Figure 1, the present invention includes cam 1, cam 1 is arranged on the gear shaft of (outward) portion's transmission case in transmission mechanism, and cam 1 can be clockwise or be rotated counterclockwise certain angle under the drive of gear shaft.Working the ratchet back shaft 5 supporting fixation is fixedly mounted on the transmission case cover plate of transmission mechanism, and interlocking ratchet 3 is connected with ratchet back shaft 5.
Ratchet 4 is connected by the power shaft of ratchet shaft with far-end door transmission case, and latch 2 is fixedly mounted on the transmission case cover plate of transmission mechanism, and limited block 6 is arranged on the transmission case cover plate of transmission mechanism.Interlocking ratchet 3 is between latch 2 and limited block 6.
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, is provided with spring 10 between bearing pin 11 and outer cylinder body 9 roof.
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 the pawl bar of interlocking ratchet 3, stirs interlocking ratchet 3 and rotates clockwise centered by ratchet back shaft 5, till the pawl bar always turning to interlocking ratchet 3 contacts with limited block 6, the claw of interlocking ratchet 3 is made to depart 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 engages with ratchet 4 under itself Action of Gravity Field, and at this moment, ratchet 4 can not rotate clockwise, namely can not distally rotate in door enabling direction, can only rotate counterclockwise, be exactly that far-end door dallies to direction of closing the door, thus reach the object of interlocking.
When two ends door is all in closed condition, the interlocking ratchet 3 at two ends and ratchet 4 be all in as shown in Figure 2 leave position, any one door can be opened.
When near-end door is opened, when needing the interlocking removing 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 stirring interlocking ratchet 3 rotates clockwise, the claw of interlocking ratchet 3 is separated with ratchet 4, ratchet 4 is in the released state shown in Fig. 2 with interlocking ratchet 3, 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, latch 2 is in the position in Fig. 1, the claw of interlocking ratchet 3 automatically engages with ratchet 4 under Action of Gravity Field own, and interlock recovers.
