Description

  The present invention relates to a passenger conveyor such as an escalator or an automatic line, and more particularly to an inspection device for inspecting an installation state of a guide rail, and a passenger conveyor provided with the inspection apparatus.

  In passenger conveyors such as escalators and autolines, passengers are transported by traveling endlessly connected steps on guide rails attached to the casing frame of the passenger conveyor. In general, a total of four rollers are attached to the step in the front-rear and left-right directions in the running direction, and these run on a total of four guide rails. If there is an error in the mounting dimensions of the guide rail, various problems may occur. For example, if the distance between the left and right rails (rail gauge) is too narrow, the roller cannot run smoothly, causing vibration and noise. In addition, if the height of each of the four rails is confined, it may cause a stagger in the step. For this reason, it is important to confirm that there are no errors in the mounting dimensions of the guide rail when the guide rail is assembled to the housing frame in the factory or installed in the building of the delivery destination.

  On the other hand, conventionally, a piano wire is laid along the longitudinal direction of the casing frame on which the step travels, and an operator measures the distance between the downward swing suspended from the piano wire and the guide rail with a tape measure or the like. The mounting dimensions were confirmed. However, in measurement using such a downward swing, there is a concern that a measurement error may occur due to the swing of the downward swing. Therefore, as a method for performing such measurement work with high accuracy, a measurement method using a laser beam as a reference has been proposed (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 7-101668

  The conventional inspection apparatus described in Patent Document 1 detects a laser oscillator arranged on a housing frame, a laser oscillated from the laser oscillator, and has a guide rail mounting dimension based on the detected laser. And a detecting device that performs confirmation, and by arranging this detecting device at a predetermined position in the longitudinal direction of the guide rail, the mounting dimensions of the guide rail at that position are measured. Therefore, in the above prior art, in order to check the mounting dimensions of the guide rail over the entire section of the rail, it is necessary to perform measurements at a plurality of locations in the longitudinal direction of the guide rail. However, there is a problem in that it takes time and effort to repeatedly move, fix, and measure the detection device. On the other hand, if it is attempted to perform measurement at a plurality of locations at once in order to reduce labor, a plurality of detection devices are required, resulting in an increase in cost. In particular, in the vicinity of the upper and lower horizontal portions of the housing frame, the relative height dimensions of the four guide rails continuously change. It is necessary to measure the location, and the above-described labor and cost increasing tendency is further increased. In the above method, it is difficult to remotely inspect after installing the passenger conveyor.

  The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to provide a passenger conveyor that can greatly reduce the labor of inspection of guide rail mounting dimensions without incurring an increase in cost. An object of the present invention is to provide an inspection device and a passenger conveyor equipped with the inspection device. Another object of the present invention is to provide an inspection apparatus that can be inspected remotely even after the passenger conveyor is installed.

A feature of the present invention that achieves the above-described object is that inspection of a passenger conveyor that inspects the mounting dimensions of four front and rear guide rails in a manufacturing stage of a passenger conveyor that transports passengers by moving endlessly connected steps. In the apparatus, a casing composed of at least two casing portions that are rotatably connected to each other, an inclination sensor that is provided in each of the at least two casing portions and measures an inclination angle of the casing portion , and A distance sensor that is provided in each of the housing portions and measures a distance between the housing portion and the guide rail, and a traveling device that travels the housing along the guide rail. That is, according to the present invention, the height dimension between the guide rails can be measured by the inclination sensor with respect to the height dimension between the guide rails only by running the casing provided with the tilt sensor and the distance sensor. ) Can be continuously measured by a distance sensor. Therefore, it is possible to inspect the mounting dimensions of the guide rail in a short time without trouble, and it is not necessary to use a plurality of detection devices to reduce labor as in the prior art, resulting in an increase in cost. Without incurring the trouble, it is possible to greatly reduce the labor of inspection of the mounting dimensions of the guide rail.

A feature of the modified example of the present invention is that in the passenger conveyor inspection device for inspecting the mounting dimensions of the guide rails of the passenger conveyor that transports the passengers by moving the endlessly connected steps, the steps are provided with the inclination of the steps. There is an inclination sensor that measures the angle and an acceleration sensor that is provided on the step and measures the acceleration of the step. That is, by providing an inclination sensor and an acceleration sensor on the back side of the step, for example, the installation dimensions of the guide rail can be measured by measuring the inclination and acceleration of the step without disturbing the operation of the passenger conveyor even after the passenger conveyor is installed. Can be inspected. Then, for example, by transferring this measurement data to the outside, it is possible to inspect remotely from a monitoring center or the like.

According to the present invention, it is possible to greatly reduce the labor for inspecting the mounting dimensions of the guide rail without increasing the cost. Moreover, according to the modification of this invention , even after installing a passenger conveyor, it can test | inspect remotely.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a passenger conveyor inspection device and a passenger conveyor equipped with the same according to the present invention will be described with reference to the drawings. This embodiment is an example in which the present invention is applied to an escalator that is one of passenger conveyors.

  First, the schematic structure of the escalator will be described with reference to FIG. FIG. 1 is a side view schematically showing the overall configuration of a general escalator. As shown in FIG. 1, the escalator includes a plurality of endlessly connected steps 1, a terminal gear 2 that circulates these steps 1, a drive device 3 that drives the terminal gear 2, and a circulator that synchronizes with the steps 1. And a housing frame 5 in which a step 1, a terminal gear 2, a driving device 3 and the like are stored.

  The step 1 is provided with a pair of left and right front guide rollers (hereinafter abbreviated as front rollers) 6 and rear guide rollers (hereinafter abbreviated as rear rollers) 7 (that is, one step 1 has four rollers). ), The front roller 6 and the rear roller 7 travel on a front roller guide rail (hereinafter abbreviated as front rail) 8 and a rear roller guide rail (hereinafter abbreviated as rear rail) 9, respectively. As shown in FIG. 1, the distance between the front rail 8 and the rear rail 9 is narrow at the inclined portion, wide near the upper horizontal portion 5a and the lower horizontal portion 5b of the housing frame 5, and continuously at the transition portion. The interval has changed. Thereby, the upper surface part of the step 1 is supported so that it may always be kept horizontal.

(First embodiment)
This embodiment is an example in the case of inspecting the installation dimensions of the guide rail at the production site (for example, in a production factory) in the production stage of the escalator.

  FIG. 2 is a perspective view showing the entire structure of the escalator inspection apparatus according to this embodiment. In FIG. 2, 10 is an inspection device for inspecting the mounting dimensions of the guide rails 8 and 9 of the escalator, 8a and 8b are rails on one side and the other side of the front rail 8, and 9a and 9b are the rear side. The rail of one side and the other side is shown among rails. The inspection device 10 is pivotally supported by the housing 11 via the support member 12 and supported by the housing 11 at a position corresponding to the front rails 8a and 8b (in other words, the same positional relationship as the front roller 6). The front running rollers 13a and 13b respectively arranged, and the shaft 11 rotatably supported by the housing 11 via the support member 14 and corresponding to the rear rails 9a and 9b (in other words, the same positional relationship as the rear roller 7) ) And rear running rollers 15a and 15b, respectively. By these front / rear travel rollers 13a, 13b, 15a, 15b, the inspection apparatus 10 can travel on the guide rails 8a, 8b, 9a, 9b.

  Reference numeral 18 denotes a motor that rotates the drive pulleys 20a and 20b around which the linearly stretched wires 19a and 19b are wound (or contacted), and 21a, 21b, 22a, and 22b guide the wires 19a and 19b. It is a guide pulley for doing. With such a configuration, when the motor 18 rotates the drive pulleys 20a and 20b and rolls the wires 19a and 19b, the front / rear travel rollers 13 and 15 travel on the guide rails 8 and 9 while the inspection apparatus 10 travels. Is supposed to move.

  Reference numerals 24a, 24b, 25a, and 25b are distance sensors that are provided in the housing 11 and measure the distances between the inspection apparatus 10 (housing 11) and the guide rails 8a, 8b, 9a, and 9b. Are tilt sensors 27a and 27b that are provided in the casing 11 and measure an inclination angle in a direction (rail gauge direction) substantially perpendicular to the traveling direction of the inspection apparatus 10 (stretching direction of the wire 19). The tilt sensor is provided on the body 11 and measures the tilt angle in the traveling direction of the inspection apparatus 10.

  The housing 11 is composed of two housing parts. FIG. 3 is a plan view of the inspection apparatus 10 as viewed from above for explaining the structure of the housing 11. In FIG. 3, the motor 18, drive pulley 20, guide pulleys 21, 22, and wire 19 are not shown, and the same parts as those in FIG. Omitted.

  As shown in FIG. 3, a housing 11 of the inspection apparatus 10 includes a housing portion 11a on one side (right side in FIG. 3) and a housing portion 11b on the other side (left side in FIG. 3). 11a, 11b has a structure that is rotatably connected via a shaft 13c of the front traveling rollers 13a, 13b. At this time, the front traveling roller 13a and the rear traveling roller 15a are attached to the housing 11a, the front traveling roller 13b and the rear traveling roller 15b are attached to the housing 11b, The inclination sensor 27a is attached to the casing 11a, and the inclination sensor 27b is attached to the casing 11b. Thereby, even if the difference in height between the front rail 8a and the rear rail 9a and the difference in height between the front rail 8b and the rear rail 9b are different, the housing portions 11a and 11b are inclined independently. Therefore, the difference in height can be inspected independently on the left and right.

  The inclination sensor 26 that measures the inclination angle of the casing 11 in the rail gauge direction is provided in the casing 11a. By the inclination sensor 26, the difference in height between the front rails 8a and 8b can be inspected. Further, the difference in height between the rear rails 9a and 9b can be obtained from the measured values of the inclination sensor 26 and the inclination sensors 27a and 27b.

  FIG. 4 is a diagram showing a schematic structure of the distance sensors 24a and 25a as viewed from the front side of the inspection apparatus (upper side in FIG. 3). As shown in FIG. 4, the distance sensor 24a emits light from the sensor head 30 and measures a horizontal distance 100 and a vertical distance 101 between the sensor head 30 and the front rail 8a. Similarly, the distance sensor 25a emits light from the sensor head 31, and measures the horizontal distance 102 and the vertical distance 103 between the sensor head 31 and the rear rail 9a. Note that the positions at which the vertical distances 101 and 103 are measured are set to be approximately near the center of the position where the front traveling roller 13a and the rear traveling roller 15a travel. The opposite distance sensors 24b and 25b have the same structure.

  With such a configuration, the rail gauge (distance between rails) between the front rails 8a and 8b is obtained from the measured value of the horizontal distance of the distance sensors 24a and 24b and the distance between the sensor heads of the distance sensors 24a and 24b. Can do. Similarly, the rail gauge between the rear rails 9a and 9b can be obtained from the measured value of the distance in the horizontal direction of the distance sensors 25a and 25b and the distance between the sensor heads of these distance sensors 25a and 25b. Further, the measured values of the vertical distances of the distance sensors 24a and 24b are used for inspecting the presence or absence of a step at the joint of the front rails 8a and 8b. That is, when there is a step at the joint between the front rails 8a and 8b, the vertical distance 101 varies when the irradiation light from the sensor head 30 passes through the step and when the front traveling roller 13a gets over the step. When these fluctuations exceed a predetermined allowable value, it can be determined that there is a step. Similarly, the presence or absence of steps in the rear rails 9a and 9b is inspected using the vertical distances of the distance sensors 25a and 25b.

  Next, a method of moving the inspection apparatus 10 having the above configuration will be described with reference to FIG. In FIG. 5, the same parts as those of FIG.

  The escalator is usually installed so that the upper horizontal portion 5a and the lower horizontal portion 5b of the housing frame 5 are horizontal, but is placed in the form shown in FIG. Sometimes. In such a case, the guide rails 8 and 9 on which the inspection apparatus 10 travels are uphill toward the right in FIG. 5 in the middle part of the housing frame 5, and the right in FIG. 5 in the upper horizontal part 5 a and the lower horizontal part 5 b. Go downhill towards. In the present embodiment, the fixed points provided at the upper end portions of the inspection device 10 and the housing frame 5 so that the inspection device 10 can travel on both the upward and downward slopes and inspect the guide rails 8 and 9. 32 and the wire 19 (wires 19a and 19b) between the inspection device 10 and a fixing point 33 (hereinafter, appropriately referred to as a pulley 33) provided at the lower end of the housing frame 5. To. At this time, the fixed point 33 has a structure in which the weight 34 is suspended via a pulley. As a result, the length of the wire 19 between the pulley 33 and the weight 34 can be varied, and the inspection apparatus 10 can be prevented from floating even if it approaches the middle valley portion of the housing frame 5.

  As shown in FIG. 2, two wires 19 a and 19 b are stretched to the left and right in the traveling direction of the inspection apparatus 10. The inspection apparatus 10 moves by repeating this with the drive pulleys 20a and 20b shown in FIG. When the inspection is performed with the casing frame 5 of the escalator placed in a normal posture, the pulley 33 and the weight 34 in FIG. 5 are unnecessary, and the wire 19 is provided only between the fixing point 32 and the inspection device 10. The wire 19 may be wound up and moved by the drive pulley 20.

  In this way, measurement data obtained by running the inspection apparatus 10 over the entire section of the escalator guide rails 8 and 9 is sent to an external determination apparatus (for example, a personal computer) by a data communication apparatus (not shown), for example. Then, it is determined whether or not the measurement data is within a predetermined tolerance range by the determination device. That is, it is analyzed whether or not the mounting dimensions of the guide rails 8 and 9 are incorrect. Note that, for example, the above-described determination device may be mounted on the inspection device 10 itself to measure data, analyze the measured data, and transfer the analysis result to the outside. In addition, a presentation device (not shown, for example, a lamp, a speaker, or the like) that visually or audibly presents the determination result by the determination device may be provided in the inspection device 10 or the external determination device.

According to the first embodiment of the passenger conveyor inspection apparatus of the present invention and the passenger conveyor including the same according to the present invention, the following operations are obtained.
That is, usually, if there is an error in the mounting dimensions of the guide rails of passenger conveyors such as escalators, various problems may occur. For example, in the escalator of the present embodiment, if there is a difference in the mounting height of the front rails 8a and 8b or the rear rails 9a and 9b, the step 1 is inclined to the left or right. When the difference in height between the front rails 8a and 8b and the rear rails 9a and 9b is different on the left and right sides, one of the four rollers 6 and 7 of the step 1 is connected to the guide rails 8 and 9. Since it is in a floating state, it causes rattling and wobbling of the step 1. Furthermore, if the rail gauge (distance between rails) between the front rails 8a and 8b or the rear rails 9a and 9b is not a predetermined dimension, the rollers 6 and 7 cannot run smoothly, and vibration, noise, etc. Cause. For this reason, when assembling the guide rails 8 and 9 to the housing frame 5 at the production site, it is important to confirm that there is no error in the mounting dimensions of the guide rails 8 and 9.

  At this time, according to the above-described prior art inspection device having the laser oscillator and the detection device, in order to confirm the mounting dimensions of the guide rails 8 and 9 over the entire section of the rails, the longitudinal direction of the guide rails 8 and 9 is determined. There is a problem that it is necessary to perform measurement in a plurality of directions, and when performing measurement with one detection device, it is necessary to repeatedly move, fix, and measure the detection device. On the other hand, if it is attempted to perform measurement at a plurality of locations at once in order to reduce labor, a plurality of detection devices are required, resulting in an increase in cost. In particular, since the relative height dimensions of the four guide rails 8a, 8b, 9a, 9b continuously change in the vicinity of the upper horizontal portion 5a and the lower horizontal portion 5b of the housing frame 5, this portion is described in detail. In order to confirm the mounting dimensions, it is necessary to measure a large number of locations, and the above-described labor and cost increasing tendency is further increased.

  On the other hand, in the present embodiment, the inspection apparatus 10 including the front and rear traveling rollers 13 and 15 arranged at positions corresponding to the guide rails 8 and 9 is configured, and all sections of the guide rails 8 and 9 are configured. The inclination angle of the casing 11 is measured by the inclination sensors 26, 27 a and 27 b, and the distance between the casing 11 and the guide rails 8 and 9 is measured by the distance sensors 24 and 25. At this time, if the guide rails 8 and 9 are assembled with predetermined dimensions, the inclination angle measured by the inspection apparatus 10 should be a constant angle over the entire section of the rail. To see if there are any deviations in the mounting dimensions of the guide rails 8 and 9, specifically whether there is a difference in the mounting height of the front rails 8a and 8b or the rear rails 9a and 9b, It is possible to inspect whether or not the difference in height between the rails 8a and 8b and the rear rails 9a and 9b is different on the left and right sides. Also, the rail gauge should be a constant value if the guide rails 8 and 9 are assembled with a predetermined dimension, so see the fluctuations in the measured values of the distance in the horizontal direction of the distance sensors 24 and 25. By this, it can be inspected whether the rail gauge is distorted. Furthermore, the presence or absence of a step at the joint of the guide rails 8 and 9 can be inspected by observing fluctuations in the measured values of the distances in the vertical direction of the distance sensors 24 and 25.

  As described above, according to the present embodiment, the various mounting dimensions of the guide rails 8 and 9 can be continuously measured only by running the inspection apparatus 10 along the guide rails 8 and 9. The guide rails 8 and 9 can be inspected in a short time without taking up. In addition, a plurality of detection devices are not required in order to reduce the labor of the inspection as in the prior art described above. Therefore, it is possible to greatly reduce the labor for inspecting the mounting dimensions of the guide rail without increasing the cost.

  In the first embodiment of the present invention, the inspection device 10 is moved using the two wires 19a and 19b that are stretched in a straight line, so that the moving direction of the inspection device 10 is substantially guided by the guide rails 8 and 9. However, it is also conceivable that the inspection apparatus 10 runs while meandering slightly from side to side. In this case, it is difficult to confirm that the guide rails 8 and 9 are straight (straightness of the guide rails) only by the distance sensors 24 and 25 provided in the inspection apparatus 10. Therefore, the linearity of the rail may be inspected by using a position measuring device described below. FIG. 6 is a plan view schematically showing the overall configuration of the position measuring apparatus.

  In FIG. 6, 150 indicates the entire position measuring device (position measuring means), and 35 indicates a position detecting device, which is installed at the position (reference position) of the fixed point 32 of the wire 19, for example. Reference numeral 36 denotes a light emitting element provided on the inspection device 10. When light emitted from the light emitting element forms an image on the image sensor 38 via the lens 37, the optical axis of the lens 37 is determined from the position of the image 39 on the image sensor 38. The azimuth angle θ of the light emitting element 36 with respect to is obtained. On the other hand, an encoder (not shown) for measuring the rotation angle of the pulley is provided on the guide pulley 21a (or other pulley) in FIG. Thereby, the distance d from the position detection device 35 to the light emitting element 36 can be obtained. From these azimuth angle θ and distance d, the relative position with respect to the reference position of the inspection apparatus 10 (here, the position of the fixed point 32) can be specified. From the position of the inspection apparatus 10 thus obtained and the horizontal distance measured by the distance sensors 24 and 25, the position of the guide rails 8 and 9 at the measurement point of each rail is obtained, thereby The linearity can be inspected. Note that the position measuring device 150 referred to in the present embodiment is composed of the position detecting device 35, the light emitting element 36, the lens 37, the imaging element 38, an encoder (not shown), and the like.

  In the first embodiment of the present invention, the inspection apparatus 10 is moved by feeding the two wires 19a and 19b with the drive pulleys 20a and 20b. A roller drive motor (not shown) for driving the travel rollers 13 and 15 is provided, and the inspection roller 10 is driven along the guide rails 8 and 9 by driving the travel rollers 13 and 15 with this roller drive motor. You may do it. Also in this case, the same effect as the first embodiment can be obtained.

(Second Embodiment)
This embodiment is an example in the case where the installation dimensions of the guide rail are inspected on site after the escalator is installed. In this embodiment, the guide rails 8 and 9 are inspected by installing a sensor module equipped with various sensors on the step 1 and operating the escalator.

  FIG. 7 is a perspective view of the step 1 showing the overall structure of the sensor module 40 which is the second embodiment of the passenger conveyor inspection device of the present invention. In FIG. 7, the same parts as those in FIG.

  As shown in FIG. 7, the sensor module 40 includes a housing 47 that is detachably provided on the step 1, and various sensors mounted on the housing 47, that is, the traveling direction and the left-right direction of the step 1. Inclination sensors 41 and 42 that measure the inclination, acceleration sensor 43 that measures vibration (acceleration) of the step 1, and the distance between the step 1 and a skirt guard (not shown) on the left and right sides of the travel space of the step 1, respectively. Distance sensors 44a and 44b for measurement are included. Reference numeral 45 denotes a determination device (determination means) for determining whether or not the measured values of the inclination sensors 41 and 42, the acceleration sensor 43, and the distance sensors 44a and 44b are within an allowable range. Etc. Reference numeral 46 denotes a presentation device (presentation means) that visually or audibly presents the determination result by the determination device 45, and specifically includes a lamp, a speaker, and the like. These determination device 45 and presentation device 46 are also mounted on the housing 47.

  An inspection method using the sensor module 40 having the above configuration will be described. First, the sensor module 40 is fixed to the upper surface of the step 1 near the lower boarding place of the escalator. In this state, the escalator is driven up, and the operation is stopped when the above step 1 reaches the vicinity of the top of the escalator. While the step 1 to which the sensor module 40 is fixed is moving, the step 1 tilts more than the allowable value, the distance between the step 1 and the skirt guard becomes less than the allowable value, or the step 1 vibrates more than the allowable value. In this case, the presentation device 46 is turned on or ringed, for example. As a result, there is a difference in the mounting height of the front rails 8a, 8b or the rear rails 9a, 9b, or the difference in height between the front rails 8a, 8b and the rear rails 9a, 9b is different on the left and right sides. It turns out that the gauge is not constant or there is a step at the joint of the guide rails 8 and 9. Therefore, if the presentation device 46 does not light or ring while the step 1 moves, it can be confirmed that the guide rails 8 and 9 are attached to a predetermined attachment dimension. Further, when the presentation device 46 is lit or ringing, since there is an abnormality in the rail portion on which the step 1 is traveling at that time, the position where the mounting dimensions of the guide rails 8 and 9 are out of order is specified. be able to.

  According to the present embodiment having the above-described configuration, as in the first embodiment described above, it is possible to greatly reduce the labor of inspection of the guide rail mounting dimensions without incurring an increase in cost. Get. In particular, according to the present embodiment, there is an advantage that the installation dimension of the guide rail of the existing escalator can be easily inspected on site. That is, while the escalator is used, the guide rail may be deformed due to aging, and there may be a difference in the height of the left and right rails or a step at the joint. However, the sensor module 40 of this embodiment is used. For example, it is possible to check whether such aging deterioration has occurred in the guide rail of the escalator by using a time not used by the passenger, for example, at night.

(Third embodiment)
This embodiment is an example in which a sensor module in which various sensors are mounted in the step 1 at the stage of manufacturing the escalator, and the installation dimensions of the guide rail are periodically inspected after the escalator is installed.

  FIG. 8 is a perspective view of the step 1 representing the entire structure of the sensor module 50 included in the third embodiment of the passenger conveyor inspection device of the present invention as seen from below. In FIG. 8, the same parts as those in FIGS. 1 and 7 are given the same reference numerals, and the description thereof is omitted.

  As shown in FIG. 8, the sensor module 50 includes tilt sensors 41 and 42, an acceleration sensor 43, and distance sensors 44a and 44b as in the sensor module 40 described above. The sensor module 50 stores the measurement values of the inclination sensors 41 and 42, the acceleration sensor 43, and the distance sensors 44a and 44b, and also has a transfer device (data transfer means) having a transfer function for transferring the measurement data to the outside. ) 51 is also installed. Specifically, the processing device 51 includes a microprocessor, a memory, a communication circuit, and the like. A displacement sensor 52 is provided on the leg 1 a of the step 1. As shown in FIG. 9, a shielding plate 53 for detecting the passage timing of the step 1 and a data communication device (data transfer means) 54 are provided on the housing 5 side of the escalator of this embodiment. The shielding plate 53 is disposed so as to face the displacement sensor 52 attached to the leg portion 1a of the step 1 described above.

  An inspection procedure by the sensor module 50 of the present embodiment having the above-described configuration will be described. When the inspection apparatus according to this embodiment is in an operating state while the escalator is normally operated, the processing apparatus 51 monitors the output of the displacement sensor 52, and the step 1 passes by the shielding plate 53 and the displacement sensor 52 When the output fluctuates to a predetermined value, the measurement values of the inclination sensors 41 and 42, the acceleration sensor 43, and the distance sensors 44a and 44b are started to be stored at regular time intervals. When the step 1 again passes by the shielding plate 53 and the output of the displacement sensor 52 fluctuates, the measurement data stored so far is transferred to the data communication device 54. The measurement data transferred to the data communication device 54 is further transferred to, for example, a remote monitoring center 55 and analyzed there.

  If all the measurement data are within the allowable range, it can be confirmed that there is no error in the mounting dimensions of the guide rails 8 and 9, and if any of the data exceeds the allowable range, the mounting dimensions corresponding to the data are obtained. It can be confirmed that there is a madness. At this time, the step 1 of the escalator circulates at a constant speed, and the measurement data is recorded at a constant time interval. Therefore, it is possible to associate the position of each of the guide rails 8 and 9 with each data. is there. Therefore, it is possible to know which part of the guide rails 8 and 9 is out of order from the measurement data.

  Note that a determination device (not shown) for determining measurement data may be provided in the sensor module 50 or the casing 5 of the escalator, and the determination result by this determination device may be transferred to the monitoring center 55. In this case, for example, the processing device 51 provided in the sensor module 50 may have a determination function, or the data communication device 54 provided in the casing 5 of the escalator may have a determination function.

  According to the present embodiment having the above-described configuration, as in the first embodiment described above, it is possible to greatly reduce the labor of inspection of the guide rail mounting dimensions without incurring an increase in cost. Get. In particular, by adopting the configuration of the present embodiment, for example, an escalator maintenance worker or the like can monitor the state of the guide rails 8 and 9 in the monitoring center 55 without going to the escalator installation site. , Maintenance work and time can be greatly reduced.
