Next, step roller 104a (front-wheel 301) is rolled and mobile on upper rail 282, until going from lower layer side
The step chain 104 in journey path is run to the front of intermediate drive device 110.Then, as shown in Figure 5, Figure 7, when the upper rail
282 when being interrupted, and step roller 104a is moved to the intermediate orbit 114 of go path, central links 113.
Next, by the shuttling movement of central links 113, make the step roller 104a that is mounted on chain link 113a to upper strata
Side is run, and assigns driving force to step chain 104.
Next, as shown in figure 1, by assigning driving force to step chain 104, make to be connected with step chain 104 is more
Individual step 30 along guide rail 25,28 from lower floor, run on the side by layer side.
Next, when the central links 113 of go path terminate, when the step chain 104 of go path is moved downwards,
Step roller 104a leaves central links 113, and is moved to the upper rail 282 positioned at upper layer side.
On the other hand, because step roller 104a is rolled simultaneously on the lower guideway 281 being configured at below intermediate drive device 110
Operation, therefore, the step chain 104 of backhaul pathways is run on the lower guideway 281, and with the central links 113 of backhaul pathways
Engaging, so as to be assigned driving force again.
(6) the fracture detection structure of step chain 104
Detection structure when being broken according to Fig. 1 and Fig. 4 to Fig. 6 to step chain 104 is illustrated.
As shown in figure 1, by elastic device 92, the rotary shaft for the driven sprocket 26 being arranged in the Machine Room 16 of lower layer side
90 exert a force to the direction for pulling step chain 104 all the time.Fracture test section 94 is provided with the elastomeric element 92.Work as orlop
The fracture of step chain 104 between the intermediate drive device 110 and driven sprocket 26 of side is so as to when causing the pulling force to weaken, fracture inspection
Survey portion 94 detects the change, and exports break signal to main control unit 50.When from fracture test section 94 input break signal
When, main control unit 50 makes main drive 18 and all intermediate drive devices 110 stop.
But, when the step chain 104 between the adjacent intermediate drive device 110,110 in truss 12 is broken, nothing
Method is detected by the fracture test section 94 being arranged on driven sprocket 26.Therefore, as shown in figure 4, in the present embodiment,
The side of the top of guide rail 282 between adjacent intermediate drive device 110,110 is arranged at is provided with proximity transducer 122.
As proximity transducer 122, for example, induction type proximity transducer, capacitance-type sensor can be both used, can also used
Optical sensor.
As shown in figure 4, in normal state, proximity transducer 122 can't detect step chain 104, and in step chain
In the case of 104 fractures, proximity transducer 122 will detect step chain 104.As shown in fig. 6, when in adjacent midway drive
When the step chain 104 that is run between device 110,110 is broken, its broken ends because of the pulling force of intermediate drive device upward
Chevron shape is bent to tilt.Therefore, proximity transducer 122 will detect the broken ends of tilting, and to main control unit
50 output break signals.When inputting break signal from proximity transducer 122, main control unit 50 makes main drive 18 and institute
Some intermediate drive devices 110 stop.
In addition, as shown in figure 1, being also set up in drive sprocket 24 and between the intermediate drive device 110 of the superiors side
There is proximity transducer 124.In the same manner as proximity transducer 122, the proximity transducer 124 also can be when step chain 104 be broken
Detect its broken ends.
(7) effect
According to present embodiment, when the step chain 104 run between adjacent intermediate drive device 110,110 is broken
When, it can be detected by proximity transducer 122, so as to stop escalator 10.
In addition, when in drive sprocket 24 and the step chain run between the intermediate drive device 110 of the superiors side
During 104 fracture, it can be detected by proximity transducer 124, so as to stop escalator 10.
In addition, when the step chain run between the intermediate drive device 110 and driven sprocket 26 positioned at orlop side
During 104 fracture, it can be detected by fracture test section 94, so as to stop escalator 10.
In addition, if being proximity transducer 122,124, then the fracture of step chain 104 can be detected, without
Hinder the operation of step chain 104.
[variation]

The side of the top of step chain 104 of backhaul pathways can also be instead arranged on.
(2) variation 2
In the above-described embodiment, proximity transducer 122,124 has been arranged on to the side of the top of step chain 104, but
It is to be not limited to that, the side of step chain 104 can also be arranged on.Now, proximity transducer 122,124 is constantly to ladder
The step roller 104a of level chain 104 distance is detected, when the distance changes, is considered as step chain
104 are broken, so as to export break signal.The reason for this is that when step chain 104 is broken, step roller 104a and phase
The distance between adjacent step roller 104a can change.
(3) variation 3
In the above-described embodiment, as the fracture test section of detection step chain 104, there is provided proximity transducer 122,
But, as shown in figure 13, detection switch 126 instead can also be set in the top of step chain 104.The detection switch
126 detection bar 128 configures the position near the top positioned at step chain 104, is broken to tilt in step chain 104
In the case of, detection bar 128 can be moved upward, and detection switch 126 is considered as step chain 104 and is broken, so as to export
Break signal.
(4) variation 4
In the above-described embodiment, the situation applied to escalator 10 is illustrated, but it is also possible to take and generation
Ground be applied to moving sidewalk in.
