Abstract
The drive mechanism of handrail band for escalator is composed of left and right pinch roller, upper side plate, C-shaped slide block, spring and screw bolt, left and right friction wheels, lower side plate, friction band under handrail band, moving fork, guide track, ribbed plate, supporting section and supporting plate. Under the drive of escalator's main shaft, handrail band and friction band move synchronously in same direction.
Description
A kind of handrail driving method of spiral moving staircase and device belong to escalator parts manufacturing technology field.
Compare with general spiral moving staircase, adopt the minor diameter spiral way, its radius of spin can be little more than one times (the horizontal projection maximum outside diameter is less than 5.4 meters), the floor area of corresponding vertical projection also can reduce more than one times, inlet can change between 230 °～410 ° with the horizontal projection spiral angle of outlet, and the orientation that is provided with of gangway can be according to the needs of building and adjustment arbitrarily in 360 ° of scopes.Its moulded novelty, attractive in appearance, the also corresponding decline of cost.But must solve series of technical for this reason.The driving method and the device thereof of handrail are one of them.With regard to present spiral moving staircase, thereby the driving of its handrail is all adopted by sprocket spindle and is driven the mode that friction wheel drives handrail again by chain, complex structure but also just can't realize when a lot of when screw diameter is little not only.
Purpose of the present invention just is to provide a kind of novelty, attractive in appearance, spiral moving staircase handrail driving method and the device of economizing ground.
Handrail driving method proposed by the invention is characterised in that: handrail 1 is to contain the hand strap driving device 25 that rubs with 9 by one to make handrail 1 and step main shaft 27 remain equidirectional, synchronized operation under step main shaft 27 drives.
According to method design-calculated hand strap driving device 25 proposed by the invention, it is characterized in that: it is by handrail 1, be pressed on the left side on handrail 1 top, right two pinch rollers free to rotate 2, be coupling with each pinch roller 2 and be positioned at the epipleural 3 at its two ends, the C type slide block 4 that welds mutually with these epipleural 3 middle parts, be pressed on the stage clip 5 and the screw rod 6 of these C type slide block 4 centres successively, a left side that is positioned at pinch roller 2 lower ends and freely rotates around axle, right each two big friction wheel 7, be enclosed within and push down handrail 1 bottom on the friction wheel 7 and the friction that two ring-shaped rubber bands that add steel wire are spliced is with 9 with two or several bearing pins of imbedding 8, tightly be enclosed within two or several shift forks 10 on the above-mentioned bearing pin 8, be fixed on shift fork 10 left sides, right both sides and the little guide wheel 11 that can freely rotate around axle, the polyurethane sleeve pipe 13 that is enclosed within shift fork 10 lower ends and fixes with nut 12, be coupling with each friction wheel 7 and be positioned at the lower side panel 14 of its both sides, weld mutually and the support section bar 15 affixed with lower side panel 14 with staircase and girder (not drawing among Fig. 1), with support the support plate 16 that section bar 15 weld mutually and can supply C type slide block 4 to be free to slide thereon, with support plate 16 Joints and be used for the needle beam 17 of studdle 6, with support gusset 18 that section bar 15 weld mutually and weld and can supply guide rail 19 formations that little guide wheel 11 slides with gusset 18 mutually thereon.Its structure is asked for an interview Fig. 1～2.
Use proof: under step main shaft 27 drove, this actuating device 25 can make handrail 1 and step main shaft 27 realize equidirectional, run-in synchronism.
In order in conjunction with the embodiments the present invention to be done detailed describing below, show as follows employed accompanying drawing number of present specification and title brief introduction:
Fig. 1: the forward cutaway view of spiral moving staircase hand strap driving device 25.
Fig. 2: the left-hand cutaway view of this actuating device 25.
Fig. 3: the handrail drive element scheme drawing that uses this actuating device 25.
Embodiment:
Ask for an interview Fig. 1～2.Described friction wheel 7 is by lower support wheel 20, the axle collar 21 affixed with it and friction wheel 7 is constituted around its wheel shaft that freely rotates 22.On the bearing pin 23 that joins with lower side panel 14, a friction band cinch bolt 24 that joins with it is arranged.
In Fig. 3, the 26th, step.When normal operation, shift fork 10 moves on guide rail 19 under 27 effects of step main shaft.Its drives friction and is with 9 to make gyroscopic movement around friction wheel 7.Because handrail 1 passes between pinch roller 2 and friction are with 9, then handrail 1 under the friction force effect just friction be with 9 drive under operation as shown in Figure 3.Just can guarantee that friction is with 9 to keep synchronous equidirectional operation with handrail 1 as long as along certain distance several actuating devices 25 are set in handrail 1 bottom.Stage clip 5, screw rod 6 can adjust the power of depressing of pinch roller 2 and use.
Though designing for the minor diameter spiral moving staircase, it promptly can be used in the escalator under any diameter.
