Detailed description of the invention
Now, the detailed description of the invention that present invention will be described in detail with reference to the accompanying.
As shown in Figures 1 to 4, the present invention is provided with casing 1 and worm-wheel shaft 3, and casing 1 meets nuclear power station shockproof requirements.Casing 1 is provided with upper cover plate 18, lower shoe 19 and side cover plate 20, and upper cover plate 18 and side cover plate 20 detachably, and are fastened by bolts on casing 1, uses for installing, debugging and observe.Worm-wheel shaft 3 is provided with upper and lower two bearings 21, and they form a fixed connection respectively by the upper cover plate 18 of bolt and casing 1 and lower shoe 19.Worm-wheel shaft 3 in casing 1 is also provided with worm gear 2, and it is adjacent with the bearing 21 be in above worm-wheel shaft 3.
Worm-wheel shaft 3 through casing 1, and stretches out from upper cover plate 18 and these two ends of lower shoe 19.The worm-wheel shaft 3 be in above upper cover plate 18 is provided with sector gear A11 and sector gear B12, and sector gear A11 is positioned at the top of sector gear B12; The worm-wheel shaft 3 be in below lower shoe 19 is provided with partial gear 7, and partial gear 7 is meshed with the breast wheel 8 that it closes on.
The present invention is also provided with tooth bar connecting rod A9 and tooth bar connecting rod B10, sector gear A11 are connected with tooth bar connecting rod A9, and tooth bar connecting rod A9 is connected with the equalizing valve of transmission system; Sector gear B12 is connected with tooth bar connecting rod B10, and tooth bar connecting rod B10 is connected with the locking device of sealed door.
The present invention is also provided with worm screw 13 and rotating shaft 15, and worm screw 13 laterally passes from the top of casing 1, and rotating shaft 15 then transverse direction is passed from the bottom of casing 1.Worm screw 13 and rotating shaft 15 are equipped with two bearings 22 in left and right, and they form a fixed connection respectively by two side plates that bolt is relative with casing 1.
Worm screw 13 is provided with tooth, and worm gear 2 is also provided with tooth, and the tooth on worm screw 13 is meshed with the tooth on worm gear 2.When worm screw 13 is rotated, worm gear 2 also can and then rotate.The left end of worm screw 13 is also provided with top handwheel 23, and it is used for the rotation of handled easily worm screw 13; The right-hand member of worm screw 13 is connected with shaft coupling 14, and shaft coupling 14 is connected with the middle part transmission case in whole transmission system.The left end of rotating shaft 15 is provided with bottom handwheel 24, and right-hand member is also connected with shaft coupling 14, and shaft coupling 14 is connected with the middle part transmission case of whole transmission system.
The present invention is also provided with interlock, and interlock is provided with notched disc A4, notched disc B5, shift fork 6 and screw axis 16, and shift fork 6 and screw axis 16 are contained on casing 1 by bearing 17.Notched disc A4 is sheathed and be fixed in rotating shaft 15, and notched disc B5 is sheathed and be fixed on worm-wheel shaft 3.Adjust the position of two notched discs, allow the recess of two notched discs be in and vertically just can realize interlock to during position.One end of shift fork 6 contacts with notched disc A4, and the other end to be set on screw axis 16 and to form fixed-link on the axial direction of screw axis 16.The two ends of screw axis 16 are equipped with end handwheel 25, and it is used for handling the clutch of interlock.When pivoting end handwheel 25 makes screw axis 16 follow rotation, the shift fork 6 be fixedly connected with screw axis 16 will stir notched disc A4, makes notched disc A4 and notched disc B5 throw off completely gradually and namely unlocks.
Below the course of work of the present invention is illustrated:
Access lock both sides transmission case coordinates other transmission cases and drive disk assembly, can carry out all functions operation to access lock.Top handwheel 23 can manipulate proximal end door, and bottom handwheel 24 can operate far-end door.When near-end door and far-end door are all in closed condition, the notch portion of two notched discs of interlock is in vertical just to position, now closely, in the sealed door of far-end any one all can free open and close separately.
When opening near-end door, rotate top handwheel 23, thus drive worm screw 13 to rotate, make worm-wheel shaft 3 also and then rotate further.The rotation of worm-wheel shaft 3 makes notched disc B5 also follow one and plays rotation, when the arc sections of notched disc B5 enter notched disc A4 notch position, block notched disc A4 make it not rotate time, thus pinned rotating shaft 15, also just reach the object of pinning far-end door, define interlocking.Meanwhile, the sector gear A11 and the sector gear B12 that are fixed on worm-wheel shaft 3 upper end turn round successively in order, and sector gear A11 drives tooth bar connecting rod A9 first to open equalizing valve, and sector gear B12 drives tooth bar connecting rod B10 to open the locking device of sealed door again; Then the and then rotation of worm-wheel shaft 3 and the partial gear 7 that rotates, drives transmission device that be adjacent, that be contained in the breast wheel 8 on on-deck plate and be connected with breast wheel 8, thus opens near-end sealed door.Handwheel direction of rotation is contrary at closing time.
When opening far-end door, rotate bottom handwheel 24, thus drive rotating shaft 15 to rotate, the notched disc A4 be connected with rotating shaft 15 is made to rotate further, when the arc sections of notched disc A4 enter notched disc B5 notch position, block notched disc B5 make it not rotate time, thus pinned worm-wheel shaft 3, also just reach the object of pinning near-end door, define interlocking.Meanwhile, the other end of rotating shaft 15 is connected with the power transmission shaft of transmission case both sides, middle part in whole transmission system by shaft coupling 14, and drives the worm screw 13 of opposite side transmission case to complete further and open the action of near-end door same sequence and open far-end sealed door.Handwheel direction of rotation is contrary at closing time.
When untiing interlocking, pivoting end handwheel 25, stirs notched disc A4 by screw axis 16 shift fork 6, notched disc A4 and notched disc B5 is thrown off completely and namely unlocks, thus realizes sealed door free switch that is near, far-end.
When recovering interlocking, counter-rotation end handwheel 25, stirs notched disc A4 by screw axis 16 shift fork 6, makes notched disc A4 return to former extreme position, namely realizes sealed door interlocking that is near, far-end.
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 the equivalent variations to do according to scope of patent protection of the present invention and amendment, all still should belong to the category that claims of the present invention is contained.
