Guidance set includes two tracks coordinated with door leaf 1, and two tracks are made on doorframe 31 and two when building Guide rail 32,31 upper end opening of doorframe, the both sides of doorframe 31 are equipped with the sliding slot moved up and down for door leaf 1, and 31 lower end of doorframe Available for the downside of parcel door leaf 1, underground railway track is passed through in 31 lower end of doorframe, and is reserved in underground railway track both sides for subway row Sail safety clearance 31a (such as this closed door device need close when, rubber seal can be placed at the 31a of safety clearance, it is ensured that It is fully sealed both when door leaf 1 and 31 times end in contact of doorframe), the leakproofness of door leaf 1 can be strengthened, two upper rails 32 are set respectively Put and be respectively aligned to two sliding slots of doorframe 31 in the upside of doorframe 31,32 position of upper rail, doorframe 31 is close to 1 backwater of door leaf Face side is equipped with the sealing device (such as sealing strip) coordinated with door leaf 1, and eight counterparties are also provided with the sliding slot of 31 both sides of doorframe The trend of the slot 31b of 24 position of shape keeper, slot 31b move towards identical with square keeper 24.
Lifting assembly includes two hoist engines 41, and two hoist engines 41 are fixed on door leaf 1 and guidance set side, and The surface of guidance set is equipped with four fixed pulleys 42, and four fixed pulleys 42 are two-by-two one group, and the steel wire rope of hoist engine 41 bypasses Fixed pulley 42 and fixed with the lifting lug of 1 upper surface of door leaf, door leaf 1 can be driven along guidance set by the startup of hoist engine 41 Trend move up and down.
Two groups of limit assemblies are separately positioned on 31 upper end both sides of guidance set doorframe, limit assembly and the limit of 1 lower part of door leaf Position seat corresponds, and every group of limit assembly includes Rocker arm 51 and motor 52, and motor 52 is welded on 31 upper end of doorframe, Rocker arm 51 and door 31 upper end of frame is hinged by axis pin, is connected between motor 52 and Rocker arm 51 by gear transmission structure, i.e., on 52 output shaft of motor Drive gear 53 is installed, driven gear 54 is welded with Rocker arm 51, is engaged between drive gear 53 and driven gear 54, rocking arm End coordinates with the limit base in door leaf.
During design, this closed door device is arranged in the one or both sides of subway platform, is entering subway tunnel compared with mass-flow This closed door device can be closed behind road, effectively plays the purpose for preventing current from directly impacting subway platform;
, it is necessary to build two upper and lower chambers along subway tunnel when building this closed door device, lower side cavity supplies door leaf 1 Subway tunnel is blocked, upper side cavity supplies to place door leaf 1 and its control device, the doorframe of guidance set during subway tunnel normal use 31 lower ends are fixed with downside chamber bottom, and underground railway track, the both sides of doorframe 31 and the both sides of lower side cavity are passed through in 31 lower end of doorframe Side wall is fixed, and two upper rails 32 of guidance set and two fixed pulleys 42 of lifting assembly are fixed on upside chamber roof, carry Two hoist engines 41 for rising component are in upper side cavity, and the height of door leaf 1 is slightly larger than the height of lower side cavity.
As shown in Figure 6
When subway is in normal operating condition, the motor 52 of limit assembly is controlled to drive the end of Rocker arm 51 to away from door leaf 1 direction is moved, and after Rocker arm 51 departs from door leaf 1, the hoist engine 41 for operating lifting assembly pulls door leaf 1 to move up, until door leaf 1 Upper end is moved to 32 extreme higher position of upper rail, 41 stopping of hoist engine action, and the motor 52 for re-operating limit assembly drives rocking arm 51 end is resisted against the limit base lower end of door leaf 1, door leaf 1 is fixed on the upside of subway tunnel, herein can also be in upper rail Travel switch is set in 32, conveniently realizes automation mechanized operation.
As shown in Figure 7
When subway tunnel needs closed state, the motor 52 of limit assembly is controlled to drive the end of Rocker arm 51 to away from door leaf 1 direction is moved, and after Rocker arm 51 departs from door leaf 1, the hoist engine 41 for operating lifting assembly drives door leaf 1 because self gravitation is to moving down Dynamic, until 1 lower face of door leaf is contacted with 31 bottom of doorframe, (31 bottom of doorframe needs and subway Crane Rail matching design, is spy Different processing, water-proofing treatment is done in the place contacted with underground railway track using rubber block);
Then the electric motor clutch 21 of locked component is started, electric motor clutch 21 is by steering gear 23 by the steering of output shaft Torque and steering angle carry out appropriate conversion and are transferred to each shaft 22, and the relatively square keeper 24 of shaft 22 rotates, then Drive eight square keepers 24 mobile (square keeper 24 is all in door leaf 1 during default conditions) to the outside of door leaf 1, due to square Upstream face offset of 24 end of keeper to door leaf 1 is close, and during keeper stretches into 31 slot 31b of doorframe, door leaf 1 is in doorframe It is close under 31 opposite effect on the doorframe 31 of 1 back side side of door leaf, between reducing between doorframe 31 and door leaf 1 Gap, prevents the two from causing since there are gap into water, further enhances the water resistance of this closed door device.
In addition, connectivity part can only accommodate door leaf 1 and pass through between upper side cavity and lower side cavity, 1 upper end of door leaf stretches out There is sealing plate, prevent current from entering upper side cavity from lower side cavity, and door leaf 1 and track and subway tunnel edge are all by close Seal apparatus seals.
Above-described is only a kind of embodiment of the utility model, it is noted that for the ordinary skill of this area For personnel, on the premise of the utility model principle is not departed from, some variations and modifications can also be made, these also should be regarded as Belong to the scope of protection of the utility model.
