Description
Technical field
The utility model relates to a kind of engaging and disengaging gear, particularly relates to the interlocking engaging and disengaging gear for the containment access lock driving mechanism of pressurized-water reactor nuclear power plant.
Background technique
Access lock is installed on Containment for PWR Nuclear Power Plant, it is mainly at reactor cold-refueling and run duration, operator, security staff, maintenance man pass in and out the passage of containment, also can be used for transporting of some mini-plant, instrument and instrument etc. simultaneously.Interlocking engaging and disengaging gear is a core component of access lock driving mechanism, its effect is to guarantee that under nuclear power station nominal situation, two fan sealed doors of access lock can not be opened simultaneously, guarantee the integrity of containment structure, again can be at cold-refueling, between turn(a)round, remove interlocking, open two fan sealed doors simultaneously.
Yet existing interlocking engaging and disengaging gear, although can meet usage requirement, but complex structure, processing, assembly process process complexity, adjustment difficulty coefficient is large, assembled in situ need to manufacture, precision is low, keeps for a long time the reliability difficulty of interlocking large, recovers interlocking adjustment programme complicated.
Summary of the invention
The utility model is exactly in order to solve existing interlocking engaging and disengaging gear complex structure, processing, assembly process process complexity, adjustment difficulty coefficient is large, and assembled in situ need to manufacture, precision is low, keeps for a long time the reliability difficulty of interlocking large, recover the technical problem of interlocking adjustment programme complexity, provide a kind of simple in structure, part is few, and processing, assembly process process is good, the reliable in function such as interlocking, releasing, maintenance, easily realize, program is simply interlocked engaging and disengaging gear.
The utility model provides a kind of interlocking engaging and disengaging gear, comprise rotating shaft and turbine shaft, in rotating shaft, be connected with far-end interlock notched disc, turbine shaft is connected with near-end interlock notched disc, also comprise screw axis, nut shift fork and bearing, nut shift fork is connected with far-end interlock notched disc, and screw axis is connected with bearing, and nut shift fork is connected with screw axis.
Preferably, also comprise operation handwheel, described operation handwheel is connected with described screw axis.
The beneficial effects of the utility model are, simple in structure, part is few, and processing, assembly process process are good, and the reliable in function such as interlocking, releasing, maintenance easily realize, program is simple; Utilize the interlocking principle of two staggered circular recess dishes, by worm-wheel shaft, rotating shaft, drive near, far-end sealed door, control open and close near, far-end door, reach the object of interlocking, guarantee when opening near-end door, far-end door is in closed condition and can not open; Or open in the process of far-end door, near-end door is in closed condition and can not open.And after release, sealed door near, far-end can free open and close.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model;
Fig. 2 is plan view of the present utility model;
Fig. 3 is interlock while the opening position view of notched disc of near-end door;
Fig. 4 is interlock while the opening position view of notched disc of far-end door.
Symbol description in accompanying drawing:
1. far-end interlock notched disc; 2. rotating shaft; 3. near-end interlock notched disc; 4. turbine shaft; 5. screw axis; 6. nut shift fork; 7. bearing; 8. operate handwheel.
Embodiment
As shown in Figure 1, 2, the utility model comprises far-end interlock notched disc 1, rotating shaft 2, near-end interlock notched disc 3, turbine shaft 4, screw axis 5, nut shift fork 6, bearing 7, operation handwheel 8.
Near-end interlock notched disc 3 is connected with turbine shaft 4, and screw axis 5 is connected with bearing 7, and operation handwheel 8 is connected with screw axis 5, and nut shift fork 6 is connected with screw axis 5, and far-end interlock notched disc 1 is fixedly connected with rotating shaft 2.Drive nut shift fork 6 is connected with far-end interlock notched disc 1.
Far-end interlock notched disc 1 can be done clockwise or counterclockwise rotation, during clockwise direction rotation, is used for closing far-end door, while being rotated counterclockwise for Kaiyuan City's end door.
Rotating shaft 2 is connected with the input shaft of far-end door transmission case.
When near-end door and far-end door are during all in closed condition, the recess of the recess of far-end interlock notched disc 1 and near-end interlock notched disc 3 is in over against position, now wherein any free switch separately all of near, far-end door.
When near-end door is during in open mode, near-end interlock notched disc 3 is in position as shown in Figure 3, in the process of opening the door, the recess position of the circular arc part of near-end interlock notched disc 3 in far-end interlock notched disc 1, blocking far-end interlock notched disc 1 can not rotate it, thereby pin rotating shaft 2, pin far-end door, to reach the object of interlocking.
When the state of far-end door in opening, far-end interlock notched disc 1 is in position as shown in Figure 4, in the process of opening the door, the recess position of the circular arc part of far-end interlock notched disc 1 in near-end interlock notched disc 3, blocking near-end interlock notched disc 3 can not rotate it, thereby pin worm-wheel shaft 4 and also pin near-end door, to reach the object of interlocking.
When need are untied when interlocking, by operation handwheel 8, turn clockwise and be contained in the screw axis 5 on bearing 7, it is release that drive nut shift fork 6 stirs that far-end interlock notched disc 1 throws off completely with near-end interlock notched disc 3, thereby realizes closely, the switch of the sealed door of far-end.
When need recover interlocking, by operation handwheel 8 be rotated counterclockwise be contained on bearing 7 screw axis 5, drive nut shift fork 6 is stirred far-end interlock notched disc 1 and is returned to former extreme position, realizes the interlocking of the sealed door of near, far-end.
