In the following, an escalator will be described as an example as a passenger conveyor.

First, the escalator 1 to which the passenger conveyor diagnostic device fixing jig according to the present embodiment is applied will be described. FIG. 1 is a schematic configuration diagram of the escalator 1 of the present embodiment. As shown in FIG. 1, the escalator 1 of the present embodiment includes a frame body 2 installed in a building structure (not shown), a control panel 3, a balustrade portion 4, a step 5, a rail 13, and a handrail 6. A drive mechanism 7, a transmission chain 8, a driving chain 9, a handrail drive device 10, a drive sprocket 11, and a driven sprocket 12 are provided. In the following description, a coordinate system is used in which the traveling direction of step 5 is the x-axis, the width direction of step 5 is the y-axis, and the vertical direction is the z-axis.

A control panel 3, a drive mechanism 7, and a drive sprocket 11 are arranged on the upper floor side of the frame body 2, and a driven sprocket 12 is arranged on the lower floor side.

The drive mechanism 7 is composed of an electric motor and a speed reducer. Electric power is supplied to the electric motor from the control panel 3, and the operation of the electric motor is controlled by the control panel 3. A belt member 14 is wound around the electric motor and the speed reducer, and the rotational force of the electric motor is transmitted to the speed reducer via the belt member 14.

Further, the transmission chain 8 is wound around the speed reducer and the drive sprocket 11, the driving force of the drive mechanism 7 is transmitted to the drive sprocket 11 via the transmission chain 8, and the drive sprocket 11 rotates.

A pair of driving chains 9 are wound around the drive sprocket 11 and the driven sprocket 12, and the driven sprocket 11 rotates to rotate the driven sprocket 12 and the driving chain 9.

A pair of rails 13 are arranged in the width direction of the frame body 2, and the plurality of steps 5 are movably supported by the pair of rails 13. Further, the plurality of steps 5 are connected endlessly via a pair of driving chains 9, and are guided by the rail 13 to circulate on the outward route side and the return route side.

The balustrade portion 4 is supported on the upper portion of the frame body 2, and is arranged on both sides of the frame body 2 in the width direction. An endless handrail 6 is attached to the balustrade portion 4. The handrail 6 is movably supported by the balustrade portion 4, and is circulated and circulated in the same direction as the plurality of steps 5 by the handrail driving device 10. As a result, the escalator 1 can safely carry the passengers who are riding on the step 5 and holding the handrail 6.

Next, step 5 will be specifically described. FIG. 2 is a perspective view showing a schematic configuration of step 5. Step 5 of the present embodiment includes a frame 17 supported by the rail 13 and a step 18 fixed to the upper portion of the frame 17. Further, the step 18 has a step board 19 on which passengers ride and a riser 37 connected to the rear end of the step board 19. Further, a plurality of cleats 20 are formed in parallel on the surfaces of the tread plate 19 and the riser 37 along the traveling direction of the tread plate 19 to improve the strength of the tread plate 19 and the riser 37. The cleat 20 meshes with a comb plate provided on the floor plate of the entrance / exit.

Next, the tread plate 19 will be specifically described. FIG. 3 is a cross-sectional view of the tread plate 19 as viewed from the x direction, and the tread plate 19 can be roughly divided into two types of structures (a) and (b). FIG. 3A shows a tread plate 19a having a bent structure, and has a structure in which a cleat 20a formed by bending a thin plate is fixed to the tread plate 19a by an adhesive means such as welding. On the other hand, FIG. 3B shows a tread plate 19b having a machined structure, and the cleat 20b and the tread plate 19b are integrally molded by cutting out a material.

Here, the y-axis direction (width direction) dimension 21a of the upper surface of the cleat 20a in the tread plate 19a of the bent structure and the y-axis direction dimension 21b of the upper surface of the cleat 20b in the tread plate 19b of the machined structure are designed to have substantially the same dimensions. There is. Further, the distance 22a between the upper surfaces of the adjacent cleats 20a in the tread plate 19a of the bent structure and the distance 22b of the upper surfaces of the adjacent cleats 20b in the tread plate 19b of the machined structure are also designed to have substantially the same dimensions. However, the cleat 20a in the tread plate 19a having a bent structure has a tapered shape in the z-axis direction (specifically, a shape that becomes thicker toward the bottom surface), whereas the cleat 20b in the tread plate 19b having a machined structure has a z-axis shape. It differs in that it is parallel to the direction (same dimension toward the bottom).

The passenger conveyor diagnostic device fixing jig according to the present embodiment can be attached to both a bent tread plate 19a and a machined tread plate 19b with one jig.

FIG. 4 is a slope view showing the structure of the passenger conveyor diagnostic device fixing jig 23 according to the first embodiment. As shown in FIG. 4, the passenger conveyor diagnostic device fixing jig 23 according to the present embodiment has a pedestal portion 27 that supports the lower surface of the portable terminal 28 and a pedestal portion 27 that is provided above the pedestal portion 27 and is provided on the portable terminal 28. It includes a terminal grip portion 25 that grips the side end portion, and a cleat grip portion 26 that is provided on both sides in the width direction on the lower side of the pedestal portion 27 and grips the cleat 20.

The passenger conveyor diagnostic device fixing jig 23 according to this embodiment has a leaf spring-like structure as a whole. The pedestal portion 27 has a curved surface shape in a steady state, and has a flat shape when the passenger conveyor diagnostic device fixing jig 23 is attached to the upper surface of the tread plate 19. As the material of the passenger conveyor diagnostic apparatus fixing jig 23, for example, a material such as polyacetal, which is hard (Rockwell hardness M78-M94), has toughness, and can be elastically deformed is used. Other materials such as polycarbonate may be used as long as they have similar characteristics.

The terminal grip portion 25 has a claw portion 24 for locking the upper surface of the side end portion of the portable terminal 28. Further, since the side end portion of the portable terminal 28 is generally chamfered, the inner surface of the terminal grip portion 25 including the claw portion 24 is concave. Therefore, according to the terminal gripping portion 25 of this embodiment, the contact area with the portable terminal 28 is increased, and the portable terminal 28 can be stably supported. The terminal gripping portion 25 may have another structure as long as the portable terminal 28 can be gripped so as not to be detached in the z-axis direction. For example, the terminal gripping portion 25 may have an L-shape (hook shape) or a rubber plate. It may be molded with an elastic body having a high coefficient of friction.

Further, the terminal grip portion 25 is not limited to a structure formed continuously along the x-axis direction at both ends of the pedestal portion 27 in the y-axis direction. For example, the terminal grip portion 25 is formed by a plurality of claw portions arranged at intervals along the x-axis direction, and the claw portions are arranged so as to face each other on both sides in the y-axis direction. You may.

Next, the cleat grip portion 26 is formed on the lower surface of the pedestal portion 27, that is, the surface opposite to the terminal grip portion 25, and is inserted between the cleats 20 formed at a predetermined interval. In the passenger conveyor diagnostic device fixing jig 23 of the present embodiment shown in FIG. 4, a cleat gripping portion 26 formed continuously along the x-axis direction is adopted in the vicinity of both ends of the pedestal portion 27 in the y-axis direction. However, it is not limited to this. For example, the cleat gripping portion 26 may be formed only in a part of the pedestal portion 27 in the x-axis direction. Further, when the portable terminal 28 is large like a tablet PC, one or more cleat gripping portions 26 may be provided not only on both sides in the y-axis direction but also between them to increase the gripping force.

Further, the cleat gripping portion 26 of this embodiment has a tapered shape in the z-axis direction, specifically, a shape that tapers toward the bottom surface of the cleat 20. Therefore, not only is it easy to insert the cleat gripping portion 26 between the adjacent cleats 20, but also the insertion amount of the cleat gripping portion 26 can be adjusted even when the tread plate 19b having a machined structure is adopted in step 5. .. Further, when the step 5 adopts the tread plate 19a having a bent structure, it is desirable that the tapered shape of the cleat gripping portion 26 is substantially the same as the tapered shape of the cleat 20a. By aligning the tapered shapes of the cleat gripping portion 26 and the cleat 20a in this way, the contact area between the side surface 26a (the surface parallel to the x-axis direction) of the cleat gripping portion 26 and the side surface of the cleat 20a is increased, and the cleat 20a This is because the gripping force can be increased. If the side surface 26a of the cleat gripping portion 26 is subjected to anti-slip treatment such as knurling, or if the cleat gripping portion 26 is formed of an elastic body having a high coefficient of friction such as a rubber plate, the cleat 20 can be more reliably formed. It becomes possible to grasp.

In this embodiment, the entire passenger conveyor diagnostic device fixing jig 23 is made of resin, but the present invention is not limited to this. For example, if the material can be elastically deformed by human power, a metal may be used as the material to reduce the thickness of the pedestal portion 27. Further, the terminal grip portion 25, the cleat grip portion 26, and the pedestal portion 27 may be formed of materials having different characteristics. The passenger conveyor diagnostic device fixing jig 23 having such a structure can be produced by using, for example, a 3D printer.

5 (a) to 5 (c) are cross-sectional views showing a procedure for mounting the portable terminal 28 on step 5 using the passenger conveyor diagnostic device fixing jig 23 of this embodiment.

FIG. 5A is a cross-sectional view showing a state when the portable terminal 28 is inserted into the passenger conveyor diagnostic device fixing jig 23. First, as shown in FIG. 5A, the technician inserts the portable terminal 28 into the upper surface of the pedestal portion 27 of the passenger conveyor diagnostic device fixing jig 23 with the display facing upward. At this time, since the pedestal portion 27 of the passenger conveyor diagnostic device fixing jig 23 has an arch shape having a predetermined radius of curvature 32, the opening width dimension 30a between the terminal grip portions 25 on both sides in the y-axis direction is a portable terminal. It is larger than the width dimension of 28, and the portable terminal 28 can be inserted. That is, when designing the passenger conveyor diagnostic device fixing jig 23, the radius of curvature 32 is selected so that the opening width dimension 30a in the steady state is larger than the width dimension of the portable terminal 28 to be gripped, for example, by about 1 mm. .. Further, when the passenger conveyor diagnostic device fixing jig 23 is in a steady state, that is, when the pedestal portion 27 has an arch shape having a radius of curvature 32, the distance 31a between the lower ends inside the cleat grip portion 26 in the width direction is sandwiched. Designed to be smaller than the distance 38 between the outer upper ends of the cleat 20 in the width direction. It should be noted that the handle portions 36 are formed on both sides of the lower side of the pedestal portion 27 in the width direction and outside the cleat grip portion 26.

FIG. 5B is a cross-sectional view showing a state when a technician deforms the passenger conveyor diagnostic device fixing jig 23 by applying force with the fingers of both hands. For example, the technician applies an attractive force 33 upward to the handle portion 36 with the index fingers of both hands so that the pedestal portion 27, which was originally arched, is flat, and the thumbs of both hands are used from above the portable terminal 28. A pushing force 34 is applied downward. Due to this deformation, the opening width dimension between the terminal gripping portions 25 is narrowed to 30b, which is smaller than the width dimension of the portable terminal 28, so that the portable terminal 28 can be gripped. On the other hand, the distance between the lower ends inside the cleat grip portion 26 in the width direction increases to 31b.

Since the pedestal portion 27 of this embodiment has an arch shape having a curved surface whose center in the width direction is convex upward in the steady state, the portable terminal 28 is placed on the upper surface of the pedestal portion 27 as described above. The portable terminal 28 can be set by a simple operation of pressing the portable terminal 28 downward. Further, since the handle portions 36 are provided at both lower ends of the passenger conveyor diagnostic device fixing jig 23, not only the pressing operation in FIG. 5B described above is facilitated, but also the passenger conveyor diagnostic device fixing jig 23 can be used. The work of carrying it to the upper surface of the tread plate 19 becomes easy.

FIG. 5C is a cross-sectional view showing a state when the passenger conveyor diagnostic device fixing jig 23 is attached to the tread plate 19a having a bent structure. The technician inserts the cleat gripping portion 26 between the plurality of cleats 20a while applying the above-mentioned attractive force 33 and pushing force 34. At this time, a restoring force 35 that tries to return to the arch shape in a steady state is generated in the passenger conveyor diagnostic device fixing jig 23, and the inner side surface of each cleat gripping portion 26 in the width direction is in the width direction of the cleat 20. By pressing the outer side surface in the y-axis direction, the cleat gripping portion 26 grips the cleat 20. Even after the cleat grip portion 26 is inserted between the cleats 20a, the claw portion 24 locks the upper surface side of the side end portion of the portable terminal 28, and the terminal grip portion 25 covers the chamfered portion of the portable terminal 28. Therefore, the portable terminal 28 is gripped by the passenger conveyor diagnostic device fixing jig 23.

Even if the passenger conveyor diagnostic device fixing jig 23 of this embodiment has a simple structure that can be manufactured at low cost, the portable terminal 28 slides on the upper surface of the cleat having a small surface area during the ride quality diagnosis of the escalator 1. Can be held so that it does not. Further, at least a part of the cleat gripping portion 26 is located outside the side end portion of the portable terminal 28 in the width direction, and the opposing cleat gripping portion 26 is located at a distant position with respect to the tread plate 19a. Can be stably supported.

Here, the work procedure of the ride quality diagnosis of the escalator 1 using the portable terminal 28 will be described. The portable terminal 28 is equipped with an acceleration sensor that detects acceleration, a microphone that detects voice, and the like. First, a technician operates the escalator 1 to stop the operation. Next, the technician sets the portable terminal 28 on the passenger conveyor diagnostic device fixing jig 23, and attaches the passenger conveyor diagnostic device fixing jig 23 on step 5 near one of the entrances and exits. After that, a technician operates the escalator 1 to operate the escalator 1, and the vibration and noise of the escalator 1 are measured by the portable terminal 28. Then, when the step 5 to which the passenger conveyor diagnostic device fixing jig 23 is attached approaches the other entrance / exit, the technician operates the escalator 1 to stop the escalator 1.

When removing the passenger conveyor diagnostic device fixing jig 23 from step 5, the technician can easily remove the passenger conveyor diagnostic device fixing jig 23 by pulling out the passenger conveyor diagnostic device fixing jig 23 upward by holding the handle portion 36. That is, according to the passenger conveyor diagnostic device fixing jig 23 of the present embodiment, the portable terminal 28 can be held or removed at a predetermined position with respect to step 5 by a simple operation without using a tool or the like. Therefore, it is excellent in terms of workability.

Further, even if the passenger conveyor diagnostic device fixing jig 23 reaches the entrance / exit with the passenger conveyor diagnostic device fixing jig 23 attached to step 5, and the passenger conveyor diagnostic device fixing jig 23 collides with the comb plate, there are a plurality of comb plates. By pushing up the cleat gripping portion 26 from the gap of the cleat 20a, the cleat gripping portion 26 is easily disengaged from the cleat 20a. That is, the passenger conveyor diagnostic device fixing jig 23 of the present embodiment can prevent the comb plate, step 5, and the like from being damaged even if it comes into contact with the comb plate during the ride comfort diagnosis, and therefore, from the viewpoint of fail-safe. But it's excellent. The end of the cleat gripping portion 26 in the x-axis direction may also be tapered so that it can be easily lifted when it comes into contact with the comb plate.

Further, since the passenger conveyor diagnostic device fixing jig 23 of this embodiment is made of a material such as polyacetal which is hard and tough, the vibration of step 5 can be transmitted to the portable terminal 28 without being attenuated, and is an escalator. Accurate ride comfort diagnosis of 1 can be realized.

FIG. 6 is a slope view showing the structure of the passenger conveyor diagnostic device fixing jig 23a according to the second embodiment. As shown in FIG. 6, the passenger conveyor diagnostic device fixing jig 23a according to the present embodiment has a structure that can handle a portable terminal 28 having various width dimensions with one device. Specifically, the terminal grip portion 25 fixed to both ends in the width direction in the first embodiment is characterized in that one terminal grip portion 25a can be attached to and detached from different positions in the width direction in the second embodiment. Is.

As shown in FIG. 6, the passenger conveyor diagnostic device fixing jig 23a of the present embodiment has a convex portion 39 having a dimension in the z-axis direction equivalent to the plate thickness of the pedestal portion 27a at the bottom of the detachable terminal grip portion 25a. Is provided. On the other hand, the same number of slide holes 29 as the convex portion 39 are formed on the upper surface of the pedestal portion 27a. The slide hole 29 has a hook shape composed of an elongated hole 29a extending in the y-axis direction and an elongated hole 29b extending in the x-axis direction. When inserting the convex portion 39 into the slide hole 29, the technician selects the elongated hole 29b at an appropriate position according to the width dimension of the portable terminal 28. The slide holes 29 may be replaced by a plurality of round holes arranged at predetermined intervals on the surface of the pedestal portion 27 in the y-axis direction. Further, the two terminal gripping portions 25 at both ends in the width direction may be detachable.

The present invention is not limited to the above-mentioned Examples 1 and 2, and includes various modifications. For example, the terminal grip portion 25 and the pedestal portion 27 may have a case shape that covers the periphery of the portable terminal 28.

Further, in the above-described first embodiment, an example in which the passenger conveyor diagnostic device fixing jig is used for the ride comfort diagnosis of the escalator 1 has been described, but it can also be used for other purposes. For example, it is possible to diagnose the tightened state of the bolt by detecting the sound and vibration when the bolt for fixing the step is fastened with the analog torque wrench by the above-mentioned passenger conveyor diagnostic device fixing jig.

Further, in the above-described first embodiment, the pedestal portion 27 has a curved surface whose center in the width direction is convex upward in the steady state, but it may be a curved surface convex downward. In this case, when the cleat grip portion 26 is inserted between the cleats 20 and the pedestal portion 27 becomes flat, the cleat grip portion 26 tends to deform outward in the width direction, and the side surface of the cleat grip portion 26 on the outer side in the width direction. However, the restoring force presses the inner side surface of the cleat 20 in the width direction.

Then, in the above-described first embodiment, when the passenger conveyor diagnostic device fixing jig 23 is attached to step 5, the pedestal portion 27 is particularly elastically deformed, so that the amount of deformation of the cleat gripping portion 26 itself is small. However, the pedestal portion 27 is not elastically deformed, and the cleat gripping portion 26 itself is largely elastically deformed, and the pedestal portion 27 is inserted between the plurality of cleats 20 to attach the passenger conveyor diagnostic device fixing jig 23 to step 5.
