The terminal gear 27 is arranged so that the terminal gear 27 can be rotated by the chain 28 in sync with the aforementioned sprocket 24 which is rotated by the not-shown drive unit. Thus, the moving handrails 15 and the steps 26 are driven at the same velocity. That is, the moving handrails 15 and the steps 26 move in sync. 2A steel cord 16 which will be described later is buried inside each moving handrail 15 to be diagnosed in the invention.
[0015]
Figs. land 2 are explanatory views of amoving handrail deterioration diagnosing device according to an embodiment of the invention. Fig. 1 is & side view, and Fig. 2 is a back view.
[0016]
The moving handrail deterioration diagnesing device A according to the embodiment shown in Fig. 1 has an X-ray source 1 which is a radiation emitting portion foremitting radioactive rays, that is, X-rays to themoving — handrail 15, and a radiation receiving portion 29 which receives the X-rays transmitted through themovinghandrail 15. Theradiationreceivingportion 29 is, for example, constituted by a scintillator 2 and a camera 3. In this configuration, the scintillator 2 producing light in response to the
X-rays is imaged by the camera 3 using a mirror.
[00171]
In addition, in the moving handrail deterioration diagnosing device
A according to the embodiment, the X-ray scurce 1 is connected to a slide rail-including post 5 through a distance changing portion 10 and a height changing portion 6. & support base 30 is connected to the base of the slide rail-including post 5, and a plurality of stopper-including casters 12 are provided on the bottom side of the support base 30. In addition, an X-ray control unit 11 for controlling the generation of X-rays emitted from the
X-ray source 1 is mounted on the top side of the support base 30.
[0018]
The aforementioned distance changing portion 10 includes a support part 10a which supports the X-ray source 1, a support post 10b which is connectedtotheradiationreceivingportion29andinsertedintoaninsertion hole provided in the support part 10a, and a fixing screw 10c which fixes the support part 10a and the support post 10b to each other. Thus, when the fixing screw 10c is loosened, the support post 10b moves relatively to the insertion hole of the support part 10a so that the distance between — the X-ray source 1 and the radiation receiving portion 29 can be set at a desired distance.
[0019]
In addition, the aforementioned height changing portion 6 can slide onasliderail of thesliderail-includingpost 5 whenahandle 6a is operated.
When the height of the height changing portion 6 is changed, the height positions of the X-ray source 1 and the radiation receiving portion 29 can be changed. [00201
Further, the height changing portion 6 and the distance changing portion 10 are connected through an angle changing portion 31. The angle changing portion 31 has a vertical rotation shaft 7which changes the vertical direction of the X-ray source 1 and the radiation receiving portion 29, that is, changes the elevation angle as indicated by the arrows in Fig. 1, and a vertical rotation shaft fixing screw 8 which fixes the rotation of the vertical rotation shaft 7 so as to fix the rotation angle thereof.
In addition, the angle changing portion 31 has a horizontal rotation shaft 17 which rotates the X-ray source 1 and the radiation receiving portion 29 horizontally, that is, in the directions of the arrows indicated in Fig. 2, and a horizontal rotation shaft fixing screw 9 {shown in Fig. 1) which fixes the rotation of the horizontal rotation shaft 17 so as to fix the rotation angle thereof. — [0021]
In order to carry out the diagnosis of detericration in the moving handrail 15 using the deterioration diagnosing device A according to the embodiment, a personal computer 14 for accumulating, analyzing and processing video data is disposed, and the camera 3 and the personal computer 14 are connected through a video cable 13 for transmitting video images.
[0022]
When the moving handrail 15 and the steel cord 16 buried in the moving handrail 15 are observed by the moving handrail deterioration diagnosing device A configured thus, the moving handrail deterioration diagnosing device A according to the embodiment is placed near a curved part 15a, 15b or 15c shown in Fig. 4. Description will be made upon the procedure in the case in which the moving handrail deterioration diagnosing device A according to the embodiment is, for example, placed near the curved part 15a to carry out the diagnosis of deterioration.
[0023]
The moving handrail 15 to be diagnosed in the embodiment moves in the same direction as the moving direction of the steps 26, on the upper surface sidewiththecurvedpartsl5aandl5bastheboundaries. Inaddition, the moving handrail 15 is pulled into a not-shown deck base on the lower surface side with the curved parts 15a and 15b as the boundaries, and moves in the opposite direction to the moving direction of the steps 26. a [0024]
To work on the preparation for installation of the moving handrail deterioration diagnosing device A according to the embodiment, first, the height changing portion 6 and the distance changing portion 10 are operated to adjust the distance between the X-ray source 1 and the radiation receiving portion 29 and the heights of the X-ray source 1 and the radiation receiving portion 29 in advance so that the curved part 15a of the moving handrail 15 canbe put between the X-ray source 1 and the scintillator 2 of the radiation receiving portion 29.
In order to diagnose deterioration in the moving handrail 15, the stoppers of the casters 12 of the moving handrail detericration diagnosing device A according to the embodiment are unlocked, and the position of the deterioration diagnosing device A is determined so that a portion to be cbserved of the curved part 15a of the moving handrail 15 can be observed.
When the positicn of the deterioration diagnosing device A is determined, thepositionofthedetericrationdiagnosingdeviceA is fixedby the stoppers of the casters 12. Further, the height changing porticn 6, the distance changing portion 10, the angle changing portion 31 and so on are operated to perform fine adjustment such that the X-ray source 1 and the scintillator 2 of the radiation receiving portion 29 can be set in proper positions in concert with the portion to be observed. As a result of the fine adjustment, —— X-rays can be emitted from the X-ray source 1 toward the scintillator 2 as indicated by an X-ray direction 4 for radiography illustrated in Fig. 1. [C0286]
In the state where the X-ray source 1 and the radiation receiving portion 29 are set as described above, the X-ray source 1 is disposed on one side of the curved part 15a of the moving handrail 15 while the radiation receiving portion 29 is disposed on the other side of the curved part 15a on one and the same surface side of the moving handrail 15 where the X-ray source 1 is disposed. Thus, the X-ray source 1 and the radiation receiving portion29%aredisposedtoput thecurvedpart 15a therebetween. Inaddition, the moving handrall deterioration diagnosing device A according to the embodiment diagnoses deterioration in the state where the curved part 15a is put between the X-ray source 1 and the radiation receiving portion 29 as described above. Incidentally, during the operation of the moving handrail deterioration diagnosing device A according to the embodiment, mainportionsincludingtheX-raysourcel andthe radiaticnreceivingportion 29 as a whole are covered with a leakage X~ray shielding pecrtion 18 made of lead cr lead rubber, as shown in Fig. 2.
[0027]
Fig. 3 is a view showing a radiographic image of a moving handrail taken by the moving handrail deterioration diagnosing device A according —_ to the embodiment.
[0028]
As shown in Fig. 3, theradiographic image takenbythemoving handrail deterioration diagnosing device A according to the embodiment, that is, the radiographic image of a steel cord 19 or wires 21 produced by the deterioration of the steel cord 19 is displayed on the personal computer 14.
[0029]
A worker who is checking the radiographic image displayed on the personal computer 14 adjusts the distance changing portion 10 for changing the distance between the X-ray source 1 and the radiation receiving portion 29 in the position where the X-ray direction 4 for radiography overlaps the steel cord 16 buried in the moving handrail. At this time, the distance between the X-ray source 1 and the radiation receiving portion 29 is made as small as possible.
[0030]
The steel cordléburiedinthemoving handrail is arrangedas follows.
That is, several thin wires are twisted into a slightly thick wire called a strand. Several strands prepared thus are further twisted inte the steel cord 16. The radiographic image of the thus configured steel cord 16 taken by the moving handrail deterioration diagnosing device A according to the embodiment is the form of a steel cord 19 shown in Fig. 3. In the embodiment, a the moving handrail 15 of the passenger conveyor 22 is radiographically imaged in the state where the steel cord 16 buried in the moving handrail is curved like a mountain in a front end portion where the moving handrail 15is foldedbackina landing zone. Whenthe steel cordl9onthe radiographic image deteriorates, untwisted wires are displayed as wires 21 in Fig. 3.
Thus, the condition of the wires 21 can be observed easily at a determination place 20. {0031]
According to the embodiment, it is possible to image the moving handrail 15 without touching the moving handrail 15. It is therefore possible to take X-ray moving images while operating the passenger conveyor 22. Further, when untwisted wires are observed at the determination place in the form of the wires 21 in Fig. 3, the X-ray source 1 and the radiation receiving portion 29 as a whole may be rotated vertically arcund the vertical rotation shaft 7 or rotated horizontally around the horizontal rotation shaft 17 so that an image can be taken to inspect only the portion of the wires in detail. That is, a still image can be taken in a desired position
S50 as to observe the deterioration condition further in detail.
[0032]
In the embodiment, the X-ray source 1 and the radiation receiving portion 29 are disposed so that the summit part of the steel cord 16 in the curved part 15a can be irradiated, as described previously. In the ee summit part of the curved part 15a, the steel ceocrd 16 is located in the outermost layer. Therefore, when this position is cbserved, the steel cord 16 can be prevented from being superimposed and radiographically imaged on another member. Thus, the diagnostic accuracy can be improved.
[0033]
In addition, frem such a point of view, it is preferable that the
X-ray source 1 and the radiation receiving portion 29 are set in the moving handrail 15 in such a manner that the summit part of the steel cord 16 in the curved part 15a can be observed.
[0034]
In additicn, the moving handrail deterioration diagnosing device
Aaccording tothe inventionhas the distance changingportion 10 for changing the distance between the X-ray source 1 and the radiation receiving pecrtion 28, sothat thedistancebetween the X-ray source l andthe radiation receiving portion 29 can be adjusted in accordance with the shape of the curved part 15a by the distance changing pertion 10. Therefore, when the distance between the X~ray scurce 1 and the radiation receiving portion 29 is made as small as possible as described previcusly, a radiographic image can be obtained with a small X-ray output. Thus, the risk of leakage of X-rays tc the cutside during diagnosis can be reduced. Even if the X-rays leak, the influence of the X-rays on the cutside can be reduced on a large scale.
In additicn, the safety of a worker can be secured easily. Further, due a to such a configuration, themoving handrail detericrationdiagnesing device
A can be applied easily to varicus forms of passenger conveyors. [C035]
As described above, the moving handrail deterioration diagnosing device A according to the embodiment irradiates the curved part 15a of the moving handrail 15 of the passenger conveyor 22 with X-rays. Accordingly, it is possible to take a radiographic image of the moving handrail 15, that is, diagnose deterioration in the moving handrail 15 without removing the moving handrail 15. Thus, the deterioration diagnosing device A including the X-ray source 1 and the radiation receiving portion 29 can be installed easily. Further, the layout can be adjusted so that the distance between the X-ray source 1 and the radiation receiving peorticn 29 can be minimized in an installation state in which the diagnosis of deterioration can be performed. Thus, the X-ray output can be reduced, and the leakage amount of X-rays can be suppressed.
[0036]
In addition, the moving handrail deterioration diagnosing device
A according to the embodiment takes a radiographic image in the state where the steel cord 16 buried in the moving handrail 15 is curved during the imaging with X-rays. Thus, untwisted wires produced by the deterioration of the steel cord 16 can be observed accurately.
[0037] — Although an escalator has been described as a passenger conveyor by way of example in the embodiment, the invention is not limited thereto, put can be applied to a general passenger conveyor such as a moving walkway.
[0038]
Although the moving handrail deterioration diagnosing device A according to the embodiment is installed near the curved part 15a by way of example so as to diagnose deterioration in the moving handrail 15, the meving handrail deterioration diagnosing device A may be installed near the curved part 15b shown in Fig. 4. Also in this configuration, accurate deterioration diagnosis can be performed without removing the moving handrail 15 from the passenger conveyor 22. That is, operations and effects similar tc those in the aforementioned embodiment can be obtained. In addition, the procedure of installation and so on can be made the same.
[0039]
Further, the moving handrail deterioration diagnosing device A according to the embodiment may be installed near the curved part 15¢ shown in Fig. 4, so as to perform the diagnosis of deterioration. In this case, the formef thedetericorationdiagnosingdeviceAhas tobe changed. However, when the deterioration diagnosing device A can be attached to such a curved part 15¢, the X-ray scurce 1 can be received within the deck base of the moving handrail 15. As a result, X~rays can be prevented from leaking, and deterioration in the moving handrail 15 can be diagnosed in accordance — with necessity without stopping service for passengers.
[0040]
The invention is not limited to the aforementioned embodiment, but may include various modifications. For example, the aforementioned embodiment has been described in detail merely in crder to make it easy to understand the invention. The invention is not always limited to one which has all the aforementioned constituents. [Reference Signs List]
