Description

The moving hand-rail testing fixture of passenger conveyors

Technical field

The present invention relates to detect the moving hand-rail testing fixture that whether has produced unusual passenger conveyors on the in-to-in tension element of the moving hand-rail that is arranged on passenger conveyors imbedding.

Background technology

Generally speaking, passenger conveyors possesses the passenger on the pedal and prevents to topple over the moving hand-rail of controlling, cooperating the ring-type of walking with the guiding rail of railing.This moving hand-rail is made of elastic bodys such as rubber, and this elastic body causes and can't tensioning be arranged in the guiding rail of railing sometimes owing to temperature traverse and long-term use etc. loses tension force.In order to prevent this situation, consistently imbed tension elements such as being provided with many steel wires in the inside of moving hand-rail and the prolonging direction of moving hand-rail.

But, imbed the occasion that a plurality of tension elements are set in moving hand-rail inside, because each tension element produces and moves under the long-term use of these tension elements, perhaps owing to reasons such as own wts, it is unusual and rupture to be easy to generate metal fatigue etc.Like this, because tension element fracture and intensity reduces, institute thinks and prevents this from occurring, and needs periodic inspection moving hand-rail in-to-in tension element, detects tension element and has or not and produce unusually, repairs and also changes tension element.

Thus, one of them example of the moving hand-rail testing fixture of the passenger conveyors of checking as tension element such in the prior art to imbed setting in moving hand-rail inside, known a kind of escalator handrail diagnostic device (for example with reference to patent documentation 1) has: imbed in inside setting a plurality of tension elements connect moving hand-rail with ring-type; X-ray generator to this moving hand-rail irradiation X ray is an x-ray irradiation device; Acceptance sees through moving hand-rail by this x-ray irradiation device and the light-receiving device of the X ray that comes; The amount of the X ray that this light-receiving device is accepted obtains device as the image that image detects; And analyze and detect the tension element of moving hand-rail N/R image processor is arranged obtain image that device obtains by this image, this image processor has: the X ray image of equal value to moving hand-rail carries out the two-dimensional high speed Fourier transform handling part that the two-dimensional high speed Fourier transform is handled; And judge the spectral discrimination portion of the tension element that has or not moving hand-rail based on the result of this two-dimensional high speed Fourier transform handling part, thereby quantitative check imbed have on the tension element that is arranged in the moving hand-rail no abnormal.

In addition, although be not the moving hand-rail testing fixture that belongs to passenger conveyors, but, as above-mentioned x-ray irradiation device, thereby as adopting X ray subject to be shone the example of prior art of the radiodiagnosis device of the data for projection that obtains subject, known have a kind of radiodiagnosis device (for example with reference to patent documentation 2), have X-ray tube that is positioned at rotating side and the collimation portion that has aperture device at direction of slip, the X ray that X-ray tube is penetrated by collimation portion is removed scattered x-ray and after direction of slip carries out the aperture adjustment to light, subject to fixation side exposes, and obtains the data for projection from the full angle of subject.

As shown in Figure 2, moving hand-rail 2 has for example 18 tension elements of a plurality of tension elements in inside, these a plurality of tension elements are that joint 201~209 described later has a plurality of tension elements that the assigned position relation disposes, and these tension elements are made of steel wire (ス チ one Le コ one De) 101~118 respectively.In addition, as Fig. 1, shown in Figure 3, have detection bodies 5 in first embodiment of the invention, 5 pairs of images of being analyzed by image processor 8 of this detection bodies limit, so that detect at least two joints with respect to the prolonging direction oblique arrangement of steel wire 101~118.This detection bodies 5 is disposed between light-receiving device 3 and the pick up camera 4 as shown in Figure 1, have with respect at least two joints of steel wire 101~118 prolonging direction oblique arrangement slit 5a of tilted configuration as one man.

Specifically, in first embodiment of the invention, as shown in Figure 2,2 of adjacency in the steel wire 101~118 as one group, are handled the joint 201~209 of steel wire 101~118.In addition,, then can reduce the intensity of part of the moving hand-rail 2 at joint 201~209 places places, tilt and separate certain intervals so joint 201~209 is arranged in prolonging direction with respect to steel wire 101~118 if these joints 201~209 are adjacent to each other.Its length dimension of arranging along same direction of the slit 5a of the detection bodies 5 that first embodiment of the invention had is set at consistent with three joints in the joint 201~209.

Promptly, respectively with joint 201,204,207, joint 202,205,208, joint 203,206,209 as one group, as shown in Figure 3, in the inspection of moving hand-rail 2, by light-receiving device 3 accept to see through the X ray of joint 201,204,207 and the light that sends with the slit 5a of same opportunity by detection bodies 5.Equally, in the inspection of moving hand-rail 2, by light-receiving device 3 accept to see through the X ray of joint 202,205,208 and the light that sends with the slit 5a of same opportunity by detection bodies 5, and, by light-receiving device 3 accept to see through the X ray of joint 202,205,208 and the light that sends with the slit 5a of same opportunity by detection bodies 5.In addition, in first embodiment of the invention, as shown in Figure 1, in these x-ray irradiation devices 1, moving hand-rail 2 as the part of checking object, light-receiving device 3, detection bodies 5, and pick up camera 4 be contained among a pair of cabinet 6a, the 6b.

In addition, image processor 8 inside have identification mechanism, this identification mechanism goes out under the unusual situation of steel wire 101~118 in continuous detecting, the change that detects each unusual light quantity is in specialized range, and detect each unusual time gap and assert it is the joint 201~209 of steel wire 101~118 in specialized range the time, when the change that detects each unusual light quantity is outside specialized range and when detecting outside at least one side of each unusual time gap outside specialized range time the scope, assert it is not the joint 201~209 of steel wire 101~118.

And, image processor 8 also has unusual decision mechanism in inside, this unusual decision mechanism is assert that mechanism regards as joint 201~209 o'clock, be judged as and on joint 201~209, do not exist unusually, assert that mechanism is assert is not joint 201~209 o'clock, be judged as on joint 201~209, exist unusual.

Action to first embodiment of the moving hand-rail testing fixture of passenger conveyors of the present invention describes below.

Fig. 4 is expression is in the image under the normal condition by the steel wire of first embodiment in the image of image processor processing shown in Figure 1 figure, Fig. 5 is the figure that the steel wire of first embodiment in the image of representing to be handled by image processor shown in Figure 1 is in the image under the error state, and Fig. 6 is the figure of expression by the image of the connector status of the steel wire of first embodiment in the image of image processor processing shown in Figure 1.

As shown in Figure 1, if from x-ray irradiation device 1 irradiation X ray, then X ray sees through moving hand-rail 2 and imbeds and is arranged on moving hand-rail 2 in-to-in steel wires 101~118.Afterwards, the concurrent bright dipping of light that light-receiving device 3 is accepted through the X ray of moving hand-rail 2 and steel wire 101~118, the light that sends is by the slit 5a of detection bodies 5.And pick up camera 4 obtains the light by slit 5a, by signal wire (SW) 7 image of obtaining is sent to image processor 8.8 pairs of images that receive from pick up camera 4 of image processor carry out Treatment Analysis.

At this moment, the state of the in-to-in steel wire 101~118 of corresponding moving hand-rail 2, the image of being handled by image processor 8 has nothing in common with each other.For example, if the state of steel wire 101~118 is normal state, then as shown in Figure 4, by image 11 equivalent arrangements and steel wire 101~118 cooresponding shadows in slit image 11a of image processor 8 processing.

On the other hand, if the state of steel wire 101~118 is an error state, then produce the fracture of steel wire 101~118 or to one-sided phenomenon such as depart from, so, as shown in Figure 5, the image of handling by image processor 8 11 in slit image 11a with the cooresponding shadow of slit 101~118 partial failure, perhaps because gravity etc. are former thereby part is not transfused to.Like this, be under the error state at the state of steel wire 101~118, light amount ratio steel wire 101~118 states that 8 pairs of image analyses of being obtained by pick up camera 4 of image processor obtain are that normal condition following time is big.

Therefore, image processor 8 as shown in Figure 7, produce at the light quantity P that the image analysis of being obtained by pick up camera 4 is obtained under the situation of change, if the change amount Δ P of this light quantity P is more than predefined light quantity P1, then be judged as and on steel wire 101~118, produced unusually, if and the not enough predefined light quantity P1 of the change amount Δ P of light quantity P then is judged as on steel wire 101~118 unusual less than producing.

Here, if image processor 8 detects and joint 201~209 cooresponding parts, then as shown in Figure 6, the image 11 that image processor 8 is handled, with slit image 11a in joint 201,204,207, joint 202,205,208 or joint 203,206,209 cooresponding each three part in be damaged with steel wire 101~118 cooresponding shadows, so these three parts are input continuously not.Therefore, the light quantity P that 8 pairs of image analyses of being obtained by pick up camera 4 of image processor obtain and the state of steel wire 101~118 are that the occasion of error state is the same, and be big when being normal condition than the state of steel wire 101~118.

Therefore, image processor 8 and the state of above-mentioned steel wire 101~118 are that the situation of error state is the same, the light quantity P that obtains as shown in Figure 8 the image that is obtained by pick up camera 4 being analyzed produces under the situation of change, if the change amount Δ P of this light quantity P is more than predefined light quantity P1, then be judged as and on steel wire 101~118, produced unusually, and go out under the unusual situation in image processor 8 continuous detecting, the change amount Δ P of each light quantity that this is unusual is in specialized range, and detect this each unusual time gap Δ t in specialized range the time, assert that then it is the joint 201~209 of steel wire 101~118 that mechanism is assert.

On the other hand, go out under the unusual situation in image processor 8 continuous detecting, when the change amount Δ P of this each unusual light quantity is outside specialized range and when detecting outside at least one side of this each unusual time gap Δ t outside specialized range time the scope, assert that it is not the joint 201~209 of steel wire 101~118 that mechanism is assert.

And, unusual decision mechanism assert mechanism assert joint 201~209 o'clock then be judged as on joint 201~209, do not exist unusual, and assert mechanism do not assert joint 201~209 o'clock be judged as on joint 201~209, exist unusual.

Here, although unusual decision mechanism assert mechanism do not assert joint 201~209 o'clock then be judged as on joint 201~209, exist unusual, but, supposing is not having on the joint 201~209 under the unusual situation, and the metal that exists in steel wire 101~118 too partly exists and the cooresponding imaginary unusual same unusual possibility of joint.Yet, for steel wire 101~118 depart from generation such as gravity unusual for, in the change that does not produce light quantity at interval, imbed in the steel wire 101~118 that is arranged on moving hand-rail 2, as mentioned above, only per two steel wires of joint 201~209 are provided with 1, so unusual decision mechanism is assert that mechanism assert that repeatedly the metal that joint 201~209 o'clock are judged as at steel wire 101~118 partly exists unusually.

First embodiment of the present invention of this structure, as mentioned above, acceptance is bigger through the light quantity P of the concurrent bright dipping of X ray of the metal part of steel wire 101~118 than acceptance through the light quantity P of the concurrent bright dipping of X ray of the joint 201~209 of steel wire 101~118 by x-ray irradiation device 1, owing to change at light quantity P with joint 201~209 cooresponding parts of steel wire 101~118, so, analyze the acceptance that obtains by pick up camera 4 by image processor 8 and see through the X ray of metal partial sum joint 201~209 of steel wire 101~118 and the light quantity P that sends, if the change amount Δ P of light quantity P is more than predefined light quantity P1, then the joint 201~209 with steel wire 101~118 detects unusually as imaginary.

And, by the mode that at least two joints 201~209 with respect to the prolonging direction oblique arrangement of steel wire 101~118 detect being limited the image of being analyzed by image processor 8 by the slit 5a of detection bodies 5, thus image processor 8 will with respect to the quantity of the joint 201~209 of the prolonging direction oblique arrangement of steel wire 101~118, be joint 201,204,207, joint 202,205,208 and joint 203,206,209 these three groups as imaginary unusual continuous the detection.

First embodiment of the present invention, under the imaginary unusual situation of image processor 8 continuous detecting, assert that mechanism assert that the change amount Δ P of each the unusual light quantity P that is detected by three groups of the slit 5a continuous detecting of detection bodies 5 and time gap Δ t are whether in specialized range, assert the joint 201~209 that steel wire 101~118, the joint 201~209 of steel wire 101~118 must be present in the inside of moving hand-rail 2, so, if the joint 201~209 of steel wire 101~118 is in normal condition, assert then that mechanism must assert and joint 201~209.Therefore, whether assert by this identification mechanism and joint 201~209, abnormality detection mechanism judges uniformly whether the joint 201~209 of steel wire 101~118 produced unusually originally, thus comprise imbed the joint 201~209 that is arranged at 18 steel wires 101~118 of moving hand-rail 2 in-to-ins interior can be quantitatively and fully check have or not on the steel wire 101~118 produce unusual.

In addition, in the first embodiment of the invention, detection bodies 5 is disposed between light-receiving device 3 and the pick up camera 4, possess and slit 5a with respect at least two joints 201~209 consistent oblique arrangement of the prolonging direction oblique arrangement of steel wire 101~118, owing to can limit the image of analyzing by image processor 8 easily and reliably the mode that at least two joints 201~209 of the prolonging direction oblique arrangement of relative steel wire 101~118 detect with the slit 5a that utilizes detection bodies 5, so, can improve the analysis precision of image processor 8.Therefore, can improve the reliability of device.

As shown in Figure 9, second embodiment of the invention and the above-mentioned first embodiment difference are, steel wire 101~118 is followed moving hand-rail 2 and is formed ring-type in first embodiment, joint constitutes 201~209 and has the gap, and in second embodiment, joint 301~309 constitutes overlay structure.Other structure is identical with first embodiment.

This occasion, image processor 8, as shown in Figure 8, the light quantity P that obtains in that the image of being obtained by pick up camera 4 is analyzed produces under the situation of change, if image processor 8 detects and joint 301~309 cooresponding parts, then as shown in figure 10, in the image of handling by image processor 8 11, with the joint 301 in the slit image 11a, 304,307, joint 302,305,308, or joint 303,306, overlapping in 309 cooresponding three parts with steel wire 101~118 cooresponding shadows, the light quantity P that obtains so 8 pairs of images that obtain from pick up camera 4 of image processor are analyzed is opposite with the situation of first embodiment, is that normal state is little than the state of steel wire 101~118.

Therefore, image processor 8 is got the absolute value of the change amount Δ P of this light quantity P under the situation of the light quantity P change that the image analysis that pick up camera 4 is obtained obtains, thereby can do same processing with the occasion of first embodiment.

Second embodiment of the present invention of Gou Chenging is compared first embodiment like this, the state difference of the joint 301~309 of steel wire 101~118, it no matter is occasion in the overlapping structure of joint 301~309, still the light quantity P that the image analysis of being obtained by pick up camera 4 is obtained produces the occasion of change, the absolute value of change amount Δ P by getting this light quantity P can access effect, the effect identical with first embodiment.Like this, can coincide with the state of joint and be mapped definitely.

In addition; in first, second embodiment of the present invention; although the mode that at least two joints 201~209,301~309 of the prolonging direction oblique arrangement of relative steel wire 101~118 detect is limited the image of being analyzed by image processor 8 by the slit 5a of detection bodies 5; but; also can have the mask mechanism that the image obtained by pick up camera 4 is implemented the mask processing and have slit 5a, thereby make image processor 8 extract specific pixel to replace detection bodies 5 by detection bodies 5.Wherein, at the pixel that extracts the border, originally in the mask change the many situation of regional light quantity under can be subjected to its influence, so image processor 8 can carry out revisal and extract specific pixel these.

In addition, in first, second embodiment of the present invention,, be not limited only to this occasion, so long as many get final product although be that steel wire 101~118 is the explanation that 18 situation is carried out with tension element.
