An access lock both sides transmission case as shown in Fig. 1 ~ Fig. 9, mainly comprises casing 3, driving gear set 4, partial gear group 1, interlock 6, power transmission shaft 7, bearing support 24, handwheel 5, connecting rod I (equalizing valve) 2, connecting rod II (locking) 11 and tooth bar 10.Wherein casing 3 is welded construction, have passed through aseismic analysis, meets nuclear power station shockproof requirements.Be welded as a whole by back shroud 21 and box plate 22, front shroud 23 is detachable, and be bolted on box plate 22, bearing support 24 is arranged on back shroud 21 and front shroud 23, and on the left of casing, side plate is detachable, for observing and Installation and Debugging.
All travelling gears and partial gear are fixed on casing front shroud 23, back shroud 21 by respective wheel shaft, have three-stage cylindrical gear to form travelling gear train 4 above, the active partial gear 15 in partial gear train 1 is connected on a shaft with the gear-driven large travelling gear 25 of the third level.By three-stage cylindrical gear, the operating physical force on handwheel 5 can be made to reduce, reach the exercisable degree of manpower.
Together with partial gear positioner is connected to partial gear, for the location of partial gear in engagement process, the active partial gear location-plate 19 that initiatively partial gear 15 connects is boss structure, driven partial gear I 16, II 17, III 18 location-plates are groove structure, both are slidably matched mutually, ensure driven partial gear I 12, II 13, III 14 when intermittent movement, there is not transmission phenomenon, ensure that initiatively partial gear 15 is rotating and reverse Shi Junneng and driven partial gear I 12, II 13, III 14 engage smoothly, reach functional requirement.Fig. 4 ~ Fig. 6 is shown in detailed cooperation.
Described transmission case installs two handwheels 5, i.e. top handwheel and bottom handwheel.By operating different handwheels 5, transmission case actions different in transmission system can be driven.Top handwheel operates by train 4 and partial gear train 1 pair of near-end door, and bottom handwheel can operate far-end door by power transmission shaft and middle part transmission case
Interlock 6 is arranged in box plate 22, and near casing front shroud 23, the large travelling gear 25 of third level gear is provided with pole 30, for coordinating interlock 6 action.During pinion rotation, pole 30 and the interlocking in interlock 6 stick up block 27 and are separated, and the stuck interlocking gear 29 of interlocking ratchet 28 reaches the object of interlocking.
During enabling, operating personnel operate transmission case top handwheel, rotate travelling gear, along with travelling gear train 4 is rotated, pole 30 and interlocking stick up block 27 and are separated, interlocking sticks up block 27 under pouring weight 26 acts on, drivening rod I 2 (equalizing valve) down moves, and connecting rod I 2 (equalizing valve) drives interlocking ratchet 28 to snap in interlocking gear 29, and interlocking gear 29 is stuck, the power transmission shaft 7 be connected with interlocking gear 29 can not operate, and reaches interlocking object.
Meanwhile, initiatively partial gear 15 engages with driven partial gear I 12, and drivening rod I 2 (equalizing valve) action, opens the equilibrated valve be connected with connecting rod I 2 (equalizing valve).Now initiatively the boss of partial gear location-plate 19 does not coordinate with the groove of driven partial gear I 12 location-plate 16, ensures that initiatively partial gear 15 is smooth and easy with engaging of driven partial gear I 12.After initiatively partial gear 15 engages with driven partial gear I 12 and throws off, initiatively partial gear location-plate 19 boss enters driven partial gear I 12 location-plate 16 groove, and driven partial gear I 12 position is fixed.
Continue operation upper part handwheel, initiatively partial gear 15 engages with driven partial gear II 13, and drivening rod II (locking) 11 action, unclamps the locking device 6 be connected with connecting rod II (locking) 11.Now initiatively the boss of partial gear location-plate 19 does not coordinate with the groove of driven partial gear II 13 location-plate 17, ensures that initiatively partial gear 15 is smooth and easy with engaging of driven partial gear II 13.After initiatively partial gear 15 engages with driven partial gear II 13 and throws off, initiatively partial gear location-plate 19 boss enters driven partial gear II 13 location-plate 17 groove, and driven partial gear II 13 position is fixed.
Continue operation upper part handwheel, initiatively partial gear 15 engages with driven partial gear III 14, is with carry-over bar 10 action, by connectors such as the bevel gears of middle part transmission case, opens hermatic door.Now initiatively the boss of partial gear location-plate 19 does not coordinate with the groove of driven partial gear III 14 location-plate 18, ensures that initiatively partial gear 15 is smooth and easy with engaging of driven partial gear III 14.After initiatively partial gear 15 engages with driven partial gear III 14 and throws off, initiatively partial gear location-plate 19 boss enters driven partial gear III 14 location-plate 18 groove, and driven partial gear III position is fixed.Now, the operation of access lock proximal seal door completes.
During operation far-end door, operate bottom handwheel, by the chain of power transmission shaft 7 and middle part transmission case, drive the transmission case of far-end to run, movement locus is identical with top handwheel, and completes the operation to far-end door.
At closing time, operating personnel operate transmission case top handwheel, contrary when direction and enabling, first be that initiatively partial gear location-plate 19 boss skids off from driven partial gear III 14 location-plate 18 groove, initiatively partial gear 15 engages with driven partial gear III 14, drive tooth bar 10 action that is connected with driven partial gear III 14, by connectors such as the bevel gears of middle part transmission case, closedown hermatic door.
Continue operation upper part handwheel, initiatively partial gear location-plate 19 boss enters driven partial gear III location-plate 18 groove, and skid off from driven partial gear II 13 location-plate 17 groove, initiatively partial gear 15 engages with driven partial gear II 13, drive connecting rod II (locking) action be connected with driven partial gear II 13, make locking device 6 action, press seal circle.
Continue operation upper part handwheel, initiatively partial gear location-plate 19 boss enters driven partial gear II location-plate 17 groove, and skid off from driven partial gear I 12 location-plate 16 groove, initiatively partial gear 15 engages with driven partial gear I 12, drive connecting rod I 2 (equalizing valve) action be connected with driven partial gear I 12, closing presure equalizing valve.
Meanwhile, along with travelling gear train 4 is rotated, pole 30 is pushed down interlocking and is stuck up block 27, drivening rod I 2 (equalizing valve) up moves, when pole 30 arrives assigned address time, interlocking ratchet 28 departs from interlocking gear 29, and restPose, on each transmission case, two handwheels all can operate.
Under particular case, if need to remove interlocking, can load and stick up with interlocking the pole that block 27 matches, making interlocking stick up block 27 can not rotate, and can remove interlocking, meet instructions for use.
In whole transmission system, by operation transmission case bottom handwheel, can complete the aforesaid operations to access lock far-end door, motion process is consistent.
