Detailed description of the invention
As Fig. 1, apparatus of the present invention are arranged on below the main door leaf of partition door, the drawer door drive mechanism having drawer door 7, two pairs of revolving doors 6 and drive drawer door 7 and revolving door 6 to move respectively and revolving door driving mechanism.
Track drawer door 7 is placed in inside main door leaf 12 slidably, in order to make the face sealing of mutually sliding, arranges rubber sheet gasket at the corresponding medial surface of main door leaf.Track drawer door 7 is driven the motion doing the lower retractable of relatively main door leaf by drawer door drive mechanism, drawer door drive mechanism is formed by two lifting units 8, is separately positioned on the both sides of main door leaf 12 bottom.The lifting unit of the present embodiment is primarily of the worm gear 81, the worm screw 82 that are configured in casing 83 internal messing, screw rod 84, be provided with the interior threaded part corresponding with screw thread on screw rod to form with the functional unit (not shown in FIG.) be connected on worm-wheel shaft, see Fig. 2, this functional unit can adopt the handwheel 62 shown in Fig. 1, also can adopt other operating grips.Casing 83 is arranged on the bottom of main door leaf 11, worm gear 81, worm screw 82 are assemblied in this casing 83 by corresponding bearing 841, interior threaded part is arranged on worm gear can two kinds of set-up modes: one arranges internal thread hole at worm gear 81 center, see Fig. 3, such worm gear also becomes an interior threaded part except forming turbine and worm decelerator with worm engaging; Another kind arranges through hole 811 at worm gear center, at least connects an interior threaded part in worm gear one end, such as nut, see Fig. 4.Screw rod 84 is rotatably connected in interior threaded part, and it is hinged with the corresponding position of track drawer door 7 that casing 83 is stretched out in screw rod 84 one end.Handle manual operational unit and make worm-and-wheel gear transmission, worm gear wheel makes corresponding interior threaded part rotate, and elevating lever moves up and down and drives the relatively main door leaf lower end of track drawer door 7 to do telescopic moving as drawer.Track drawer door 7 to be moved downward on track plane by the space on airtight main door leaf lower surface to track between plane, as Fig. 5.Distance as the screw rod movement in two lifting units is different, then track drawer door 7 will do certain rotation, can adapt to the tight requirements of non-horizontal orbital plane, and such as, on the track of track turns, plane is airtight, as Fig. 6.
In order to keep the sealing of main door leaf and drawer door preferably, the bonding surface that main door leaf slides corresponding to track drawer door 7 arranges sealing mat 129(see Fig. 2), and two ends, drawer door left and right are designed to arc surface, when drawer door produces rotation, these both ends of the surface still can be tightly connected with corresponding sealing surface inside main door leaf.
Use apparatus of the present invention need place airtight piece 03 in track both sides, in order to coordinate revolving door to seal the space of track 01 both sides.At ordinary times in order to the traveling of subway train, need between track 01 and airtight piece 03 to leave space 04, refer to Fig. 7, the revolving door 6 that this space is rotated by two couple being separately positioned on the symmetrical both sides of underground railway track is airtight, and revolving door 6 corresponds to track side and is provided with the track breach 61 holding this siding track side.Revolving door 6 is driven by revolving door driving mechanism, as Fig. 8, this revolving door driving mechanism have engage each other and heavy line part in the partial gear 61(Fig. 6 arranged on revolving door circumference) and control member.As mentioned above, control member can be handwheel or handle etc., and the present embodiment adopts handwheel 62, and this handwheel is connected to the roller end of revolving door 6.Hand wheel 62, is engaged each other by tooth on two revolving doors 6, and revolving door 6 rotates to track side, until contained by track, the space 04 of airtight track both sides.Or rotate to the orbital direction left, revolving door is opened.Adopt revolving door 6 can carry out airtight timely to the reserved space of track both sides, do not need to go airtight piece that finds correspondence when there is crisis situations and clog, adapt to the emergency cut-off situation to subway tunnel especially.
In order to carry out locking to drawer door and make main door leaf coupling mechanism force be evenly distributed, revolving door driving mechanism arranges locking unit, as Fig. 9, this locking unit has crank 21 and connecting rod 20, crank is located in the rotating shaft of corresponding revolving door, one end of connecting rod connects lock pin 31, and be provided with pin-and-hole 72 in drawer door one end, during locking, lock pin 31 inserts in pin-and-hole 72.Because drawer door is the bottom being connected to main door leaf, in order to carry out snap close to main door leaf bottom by lock pin 31, make the locking area of winner's door leaf larger, coupling mechanism force is evenly distributed, and locking is more reliable.In order to keep the locking state of revolving door 6, at the correspondence position of revolving door 6 and main door leaf 12, pin-and-hole is set respectively, then inserts in this two homoaxial hole with pin 64, the locking state of Reliable guarantee revolving door 6.
The present invention can also carry out alternative formation second embodiment to some mechanisms in above-mentioned embodiment.In the second embodiment, adopt the drawer door drive mechanism and revolving door driving mechanism that are different from the first embodiment scheme, other structures are all identical with the first embodiment, therefore repeat no more.
Drawer door drive mechanism in the present embodiment, as shown in Figure 10, there are two lifting units 8, this lifting unit 8 is arranged on main door leaf 12 bottom and has casing 87, the bevel gear of pair of meshing is provided with in it, in order to reach the bevel gear that labour-saving object adopts pair of meshing diameter not wait, wherein gear wheel 86 center is fixedly connected with axle sleeve 862, this axle sleeve center is provided with screw and is rotationally connected with in casing 87 by bearing 861, second screw rod 84 is screwed in lower end in axle sleeve 862 and is connected with the drawer door 7 be plugged in main door leaf 12, by being provided with sealing mat 11 between drawer door 7 and main door leaf 12.Equally, cone pinion 85 is rotationally connected with in casing 87 by bearing 851, and this cone pinion shaft extension goes out outside fan 12 and is connected with handwheel 87.When needing the space on opening and closing track between plane and fan 12 lower surfaces, hand wheel 87, the bevel-gear rotating of pair of meshing, axle sleeve 862 rotates with large bevel gear, under the promotion of corresponding screw thread, screw rod 84 drives drawer door to move up and down, and realizes the open and close action of drawer door.In order to the gap better between airtight main door leaf 12 and drawer door 7, be provided with sealing mat 128 in main door leaf 12 correspondence with the side that drawer door 7 is combined.
The second revolving door driving mechanism of the present embodiment has intermeshing two pairs of gears, each gear 65 independent of with the second revolving door 6, as shown in figure 11, often pair of gear connects 65 in the rotating shaft of the second revolving door of correspondence, one control member is connected to the roller end of the second revolving door, the control member of the present embodiment is adopt the shaft support of handwheel 62, the second revolving door in being connected on the bearing 67 on main door leaf 12.Hand wheel 62, by engaging each other of two gears 65, the second revolving door 6 rotates to track side, until contained by track, the space 04(of airtight track both sides participates in Fig. 7).Or rotate to the orbital direction left, the second revolving door is opened.
