Specific embodiment

With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Ground description, it is clear that described embodiment a part of embodiment only of the invention, rather than the embodiment of whole.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

Many details are elaborated in the following description in order to fully understand the present invention, but the present invention can be with It is different from alternate manner described here to implement using other, those skilled in the art can be without prejudice to intension of the present invention In the case of do similar popularization, therefore the present invention is not limited by following public specific embodiment.

As shown in Figure 1-2, the invention discloses a kind of corridor staircase, including by means of suspension arrangement 1 building is arranged on Track 3 and the cross axle chain 7 in track 3 below terraced 9 top boards, the bearing of trend and balustrade of the track 3 Bearing of trend it is identical, also include being arranged on the tooth bar 2 of the top of track 3, be arranged on 7 liang of cross axle chain by means of carrier bar 3-1 Two sets drive mechanisms 3 at end, be fixedly mounted on two copper bars 5 of the lower section of track 3, in the middle part of cross axle chain 7 at least Two sets of electric supply installations 6 and hanging the end of cross axle chain 7 lifting seat 8-2, tooth bar 2 and copper bar 5 it is parallel with track 3, The driving means are engaged with tooth bar 2, and driving means are used to drive cross axle chain 7 to move along track 3, the electric supply installation 6 Power for electrically connecting with two copper bars 5 and for drive mechanism 3.

Referring to accompanying drawing 6-7, the geared surface of tooth bar 2 is down-set and tooth bar 2 is located at the upper center of track 3, the two ends of tooth bar 2 Gatherer is respectively provided with, the drive mechanism 3 includes motor 3-7, main shaft 3-9, chain-drive mechanism 3-8, buffer gear cold 3- 6th, idler gear 3-5 and drive gear 3-2, the motor 3-7 are fixedly mounted on bracing frame lower end, and main shaft 3-9 is arranged on Bracing frame middle part, motor 3-7 clutch ends connect main shaft 3-9 ends by means of chain-drive mechanism 3-8, in main shaft 3-9 Fast pulley 3-11 and buffer gear cold 3-6 is installed in portion, and fast pulley 3-11 is bonded with main shaft 3-9, and buffer gear cold 3-6 is located at fast pulley 3-11 sides and bearing is installed between main shaft 3-9, buffer gear is installed between fast pulley 3-11 and buffer gear cold 3-6, it is described The symmetrical inserting side plate 3-4 in bracing frame inner side, the drive gear 3-2 are arranged on bracing frame top, buffer gear cold by means of wheel shaft Idler gear 3-5 is installed between 3-6 and drive gear 3-2, the wheel shaft two ends of drive gear 3-2 fixedly mount for and cross axle The carrier bar 3-1 of the connection of chain 7, carrier bar 3-1 outside is respectively mounted roller, and coaxially fixed installation is led for the drive gear 3-2 sides Enter gear 3-3, importing gear 3-3 is used to be engaged with the gatherer of the end of tooth bar 2, because the drive mechanism in the present invention includes Two sets of motors and gear drive, and two sets of drive mechanisms and pinion rotation mechanism are separately positioned on cross axle chain Two ends, meanwhile, to install for convenience, the tooth bar in the present invention is only arranged in track tilting section, is disconnection shape at horizontal turning State, when the drive gear of gear drive is before being pushed to and being engaged with next toothed rack, because drive gear is in idle running State, it is understood that there may be the situation that sliding tooth wheel and rack can not be engaged normally, or even first of the tooth of drive gear and tooth bar Tooth top is dead, in order that first tooth of sliding tooth wheel and rack is smoothly engaged, engages in first tooth of sliding tooth wheel and rack Fixed position before arranges gatherer, while importing gear is coaxially fixedly installed with drive gear, gatherer is arranged side by side Installed in the block structure of tooth bar front end side, block structure bottom surface is provided with circular arc projection, and circular arc is raised to be located at tooth bar first The corresponding position in tooth front, when drive gear is pushed to tooth bar front end, imports gear and first engages with circular arc projection, and circular arc is convex Rise and stir importing gear rotation, drive gear rotates simultaneously with gear is imported, it is therefore intended that promote drive gear to rotate to can The state normally engaged with first tooth of tooth bar, but due to making drive gear and motor in the presence of gatherer It is asynchronous, it is to solve nonsynchronous problem, the present invention arranges buffer gear between buffer gear cold and main shaft, asynchronous when occurring Situation when, can occur in the presence of buffer gear between buffer gear cold and main shaft certain angle buffering deflection, work as drive After moving gear is normally engaged with tooth bar, buffer gear cold, idler gear and drive gear enter Synchronous Transmission state.

Referring to accompanying drawing 8-10, the buffer gear includes being symmetrically and fixedly mounted to two pairs of U-shaped bullets on the outside of buffer gear cold 3-6 Spring steel disc 3-10 and two buffer bar 3-12 being fixedly mounted on the inside of fast pulley 3-11, two buffer bar 3-12 and two pairs of U-shapeds Spring steel plate 3-10 is in be symmetrically installed up and down both with respect to the axis of main shaft 3-9, and the buffer gear cold 3-6 is provided with relative to master The axis of axle 3-9 is in laterally zygomorphic twice arc long slot bore 3-12, and two buffer bar 3-12 are each passed through the arc of correspondence survey Long slot bore 3-12, buffer bar 3-12 open end is located between two U-shaped spring steel plate 3-10 on the outside of arc long slot bore 3-12, when When drive gear is hindered in running, cause drive gear asynchronous with the rotating speed of motor, now drive gear Resistance passes to buffer gear cold by idler gear, and due to being flexibly connected between buffer gear cold and main shaft, idler gear is transmitted Resistance buffer gear cold can be driven to rotate in the range of certain angle around main shaft, reach buffering purpose；Work as buffer gear cold Rotate when state is killed, by the synchronous rotation of intermediate gear drives drive gear；When resistance disappears, in spring steel plate Pressure under, buffer gear cold recovers to intermediateness.

Referring to accompanying drawing 11-12, the electric supply installation 6 includes base plate 6-3, is symmetrically mounted on two pieces of T of base plate 6-3 upper surfaces Shape carrier bar 6-1 and two sets of contact device 6-2 being symmetrically installed, two sets of contact device 6-2 are located at respectively outside two pieces of T-shaped carrier bar 6-1 Side, structure that T-shaped carrier bar 6-1 is used for and cross axle chain 7 is connected, contact device 6-2 is used to electrically connect two copper bars 5.
