Description
Technical field
The present invention relates to a kind of engaging and disengaging gear, particularly relate to the interlocking engaging and disengaging gear of the containment access lock driving mechanism for 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 the transport 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 guarantee that two fan sealed doors of access lock under nuclear power station nominal situation can not be opened simultaneously, ensure the integrity of containment structure, again can at cold-refueling, between turn(a)round, remove interlocking, open two fan sealed doors simultaneously.
But 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 needs manufacture, precision is low, keep the reliability difficulty of interlocking large for a long time, recover interlocking adjustment programme complexity.
Summary of the invention
The present invention is exactly to solve existing interlocking engaging and disengaging gear complex structure, processing, assembly process process complexity, adjustment difficulty coefficient is large, and assembled in situ needs manufacture, precision is low, keep the reliability difficulty of interlocking large for a long time, recover the technical problem of interlocking adjustment programme complexity, there is provided a kind of structure simple, part is few, and processing, assembly process process are good, the reliable in function such as interlocking, releasing, maintenance, easily realize, program simply interlock engaging and disengaging gear.
The invention provides a kind of interlocking engaging and disengaging gear, comprise rotating shaft and turbine shaft, rotating shaft is 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; Far-end interlock notched disc can be done to rotate clockwise or counterclockwise, for closing far-end door when clockwise direction rotates, for Kaiyuan City's end door when being rotated counterclockwise; Rotating shaft is connected with the input shaft of far-end door transmission case.
Preferably, also comprise operation handwheel, described operation handwheel is connected with described screw axis.
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; Utilize the interlocking principle of two staggered circular recess dishes, drive near, far-end sealed door by worm-wheel shaft, rotating shaft, control open and close that are near, far-end door, reaching the object of interlocking, guaranteeing when opening near-end door, far-end door is in closed condition and can not opens; Or open in the process of far-end door, near-end door is in closed condition and can not opens.And after unlocking, sealed door that is near, far-end can free open and close.

Fig. 3 is the position view of near-end door interlocking notched disc when opening;
Fig. 4 is the position view of far-end door interlocking notched disc when opening.
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 present invention includes 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 to rotate clockwise or counterclockwise, for closing far-end door when clockwise direction rotates, for Kaiyuan City's end door when being rotated counterclockwise.
Rotating shaft 2 is connected with the input shaft of far-end door transmission case.
When near-end door and far-end door are all in closed condition, the recess of far-end interlock notched disc 1 and the recess of near-end interlock notched disc 3 are in just to position, now closely, far-end door wherein any one all can free switch separately.
When near-end door is 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 circular arc part of near-end interlock notched disc 3 is in the notch position of far-end interlock notched disc 1, blocking far-end interlock notched disc 1 makes it not rotate, thus pin rotating shaft 2, namely pin far-end door, to reach the object of interlocking.
When far-end door is in the state opened, far-end interlock notched disc 1 is in position as shown in Figure 4, in the process of opening the door, the circular arc part of far-end interlock notched disc 1 is in the notch position of near-end interlock notched disc 3, blocking near-end interlock notched disc 3 makes it not rotate, thus namely pinning worm-wheel shaft 4 also pins near-end door, to reach the object of interlocking.
When untiing interlocking, to be turned clockwise the screw axis 5 be contained on bearing 7 by operation handwheel 8, drive nut shift fork 6 is stirred far-end interlock notched disc 1 and is thrown off completely with near-end interlock notched disc 3 and namely unlock, thus realizes the switch of the sealed door of near, far-end.
When interlocking need be recovered, 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, namely realizes the interlocking of the sealed door of near, far-end.
