Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention program is described in detail.
Wicket 7 mechanism of the subway tunnel door that the present embodiment provides, including the wicket 7 being articulated with on the main door of subway tunnel, rotates casing, drive mechanism, clutch and blocking mechanism, sees Fig. 1.The wicket 7 of subway tunnel can close space corresponding above main door 2, for the harmful gas occurred in tunnel carries out emergent obstruct, it is ensured that the life security of personnel on subway.Further design is also to include by rotating casing, drive mechanism and clutch.Rotate casing, be fixed on wicket 7 and directly drive wicket 7 to rotate.Drive mechanism, is provided with the first output shaft, is in transmission connection in rotating casing, realizes the keying of wicket 7 around its jointed shaft in order to drive wicket 7 to rotate.Clutch, is arranged on the first output shaft of drive mechanism, in order to realize drive mechanism and to rotate being temporarily separated and gradually engaging of casing housing.
Drive mechanism is mainly made up of the first output shaft 5, vertical rotating shaft 3, bevel gear gear unit 1 and Worm Wheel System unit 4.First output shaft 5 is horizontally supported on main door 2.One end of first output shaft 5 is in transmission connection by one end of Worm Wheel System unit 4 with vertical rotating shaft 3, and the other end stretches in rotating box through the driving hole rotating casing.Vertically the other end of rotating shaft 3 is in transmission connection with handwheel 10 by bevel gear gear unit 1.
In the present embodiment, bevel gear gear unit 1 by the 3rd casing, be arranged at the 3rd casing 101 in intermeshing 3rd bevel gear 102 and the 4th bevel gear 103 form, see Fig. 5.The rotating shaft of the 3rd bevel gear the 102, the 4th bevel gear 103 horizontal and vertical respectively is arranged, and one end of the rotating shaft of the 3rd bevel gear 102 is stretched out and is connected with handwheel 10 outside the 3rd casing 101, and the 4th umbrella tooth 103 is connected respectively with the lower end of vertical rotating shaft 3.
Worm Wheel System unit 4 is mainly made up of worm gear 41, worm screw 42 and the second casing 43, sees Fig. 6.Second casing 43 is arranged at above main door 2 and on the position corresponding with rotating casing 8, and the first output shaft 5 is connected with worm screw 42 in stretching into the second casing 43.Worm gear 41 engages each other with worm screw 42.Worm gear 41 is connected with the upper end of vertical rotating shaft 3.
In order to realize rotating the casing control function to wicket 7 closedown structure, the rotation casing of the present embodiment uses the first casing.The housing of the first casing is provided with the first splined hole 81 relative to the one side of the first output shaft 5.First output shaft 5 is in transmission connection with the gear train in the first casing through the first splined hole 81 relative to one end of the first casing, and the first output shaft 5 is provided with the first spline 51 corresponding at the first splined hole 81.
Clutch is the engaging sleeve 6 with second splined hole 62 suitable with the first external splines.Engaging sleeve 6 is socketed on the first spline 51 by splined hole, it is achieved engaging sleeve and the first output shaft axially slidable and connecting without relative rotation.Engaging sleeve 6 is circumferentially opposed is provided with second spline 61 suitable with the first splined hole 81 in gear-box side, and opposite side is provided with cannelure.
This wicket mechanism also includes a manipulation driving lever 9, handles driving lever 9 and can be connected on main door 2 radial rotating, is perpendicular to the first output shaft 5 and arranges.The one end handling driving lever 9 is correspondingly provided with two group bars 91 suitable with cannelure, dials bars 91 for two and is stuck in respectively and the upper edge of cannelure radial direction, lower edge.When dialling bar 91 and rotating with manipulation driving lever 9, cell wall can be promoted, and then drive engaging sleeve 6 to reciprocatingly slide on the first spline 51.The other end handling driving lever 9 connects the stick 92 having for driving manipulation driving lever 9 radial rotating.Need the most easily to rotate stick 92 in view of operator and come clutch the first output shaft 5 and the first casing, therefore use the structure of a kind of laborsaving lever, i.e. need the length of two groups of bars 91 to be respectively less than the length of stick 92.
Handle driving lever 9 by dialling bar 91 and the clamping realization of groove and being flexibly connected of engaging sleeve 6, when dialling bar 91 and synchronously rotating to the first casing side with stick 92, engaging sleeve 6 realizes the second spline 61 and progressively joint of the first spline 51 under the promotion dialling bar 91, drive mechanism can drive the first casing housing around the first output shaft 5 synchronous axial system, completes the open and close of wicket 7.When wicket 7 completely closes, rotating stick 92 and make to dial bar 91 synchronously to opposite side rotation, engaging sleeve 6 is under the promotion dialling bar 91, and the second spline 61 is temporarily separated with the first spline 51, completes " locked in " operation.
After wicket 7 is closed, after rotating operation driving lever makes engaging sleeve 6 and the first casing housing depart from, rotate manipulation driving lever 9 further and can control locking and the unblock of wicket 7.The wicket that the present embodiment provides is a cavity structure, and locking mechanism is arranged in the cavity of wicket, and blocking mechanism as shown in Figure 8, is mainly made up of cross gear frame 13, connecting rod 11 and lock pin 12.Crux gear frame 13 is rotatably connected at rotation casing 8, and four driving arms of crux gear frame 13 are in transmission connection with corresponding lock pin 12 by connecting rod 11 respectively.The surrounding side of wicket inner chamber is respectively equipped with slideway 14 corresponding to the position of lock pin so that lock pin crux gear frame, connecting rod driving under slide along slideway inwall.
Corresponding the present embodiment rotate casing as it is shown in fig. 7, for be provided with the second output shaft 86 and in be provided with the first casing of gear transmission chain.Second output shaft 86 is horizontally disposed with, and is in transmission connection with described cross gear frame.First casing is provided with driving hole corresponding to the position of drive mechanism output shaft, and input tooth and first output shaft of gear transmission chain are in transmission connection.Said gear driving-chain is mainly made up of intermeshing input bevel gear 82 and the first bevel gear 83 and intermeshing output bevel gear 85 and the second bevel gear 84.Input bevel gear 82, output bevel gear 85 are connected on output shaft and the gear transmission chain output shaft of drive mechanism.First, second bevel gear 84 is connected to the upper and lower side of a vertical axis.
When crux gear frame 13 rotates clockwise, connecting rod 11 promotes the lock pin 12 of correspondence to slide outside wicket 7 respectively, until entering locked groove, thus realizes the locking of wicket 7;When crux gear frame 13 rotates counterclockwise, further the respectively lock pin 12 of correspondence of connecting rod 11, to wicket 7 inner slide, until departing from locked groove, thus realizes the unblock of wicket 7.The most just the locking of wicket 7, unblock and sealing function are achieved.
The engaging sleeve that wicket 7 mechanism that the present embodiment provides by drive mechanism, handles driving lever control and the cooperation transmission of the rotation casing with splined hole, only need to rotate the handwheel being below and can complete to be opened by wicket, close, the most convenient;The locking of door is to carry out transmission block action by gear drive in rotating box body, simple and reliable;Simultaneously because rotate the setting of casing, the structure of the present invention is made to simplify.
