Detailed Description
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Duplicate descriptions are appropriately simplified or omitted. In the drawings, like reference numerals designate like or corresponding parts throughout the several views.
Embodiment 1.
Fig. 1 is a cross-sectional view showing an example of an escalator. The escalator has a truss 1 and steps 2. Truss 1 is erected on the upper and lower floors. The passenger rides on the steps 2 and moves from a landing (not shown) to a landing 3. That is, fig. 1 shows an ascending escalator. The escalator shown in fig. 1 may also be a descending escalator.
A machine room 4 is arranged below the landing entrance 3. The machine room 4 is a space formed inside the truss 1. The machine room 4 is blocked by the floor 5. The floor 5 forms the floor of the landing gear 3. A motor 6 and a control device 7 are provided in the machine room 4. The motor 6 drives a sprocket 8. The control device 7 controls the motor 6.
The sprocket wheel 10 and 11 are provided on the shaft 9 provided with the sprocket wheel 8. Sprockets 10 and 11 rotate with sprocket 8. A step chain 12 is wound around the sprocket 10. The step chain 12 is provided with a plurality of step shafts 13. The steps 2 are fixed to the respective step shafts 13. Thus, a plurality of steps 2 are connected to the step chain 12. The steps 2 are moved by being pulled by the step chain 12.
Around the sprocket 11, an armrest chain 14 is wound. The handrail chain 14 transmits the driving force of the motor 6 to the driving device 15. The driving device 15 drives the moving handrail 16.
The step chain 12 and the handrail chain 14 are examples of chains used in an escalator. Other chains may also be used in an escalator. For example, the driving device 15 includes a chain for rotating a roller in contact with the moving handrail 16.
In the inspection of the escalator, maintenance personnel measure the elongation of the chains, and compare the measured elongation with a reference value. In order to determine this reference value, maintenance personnel need to determine the size of the chain. Hereinafter, a tool for determining the size of a chain used in an escalator will be described in detail.
First, the structure of the chain will be described with reference to fig. 2 and 3. Fig. 2 is a side view showing an example of a chain. Fig. 3 is a plan view showing an example of a chain. The chain is provided with inner links 20 and outer links 21.
The inner link 20 includes a pair of inner plates 22, a pair of bushings 23, and a pair of rollers 24. The pair of inner plates 22 are disposed so as to face each other. Each sleeve 23 connects a pair of inner plates 22. The roller 24 is rotatably provided to the sleeve 23. The sleeve 23 penetrates the roller 24. The roller 24 is disposed between the pair of inner plates 22.
The outer link 21 includes a pair of outer plates 25 and a pair of pins 26. The pair of outer plates 25 are disposed so as to face each other with the inner link 20 interposed therebetween. Each pin 26 connects the pair of outer plates 25. The pin 26 penetrates the sleeve 23. Thereby, the outer links 21 are coupled to the inner links 20.
Fig. 4 is a diagram showing an example of the determination tool 30 in embodiment 1. The determination tool 30 includes a plate member 31 and a string member 32. As an example, the plate member 31 is constituted by an iron plate having a certain thickness. The plate member 31 is formed with a plurality of cutouts corresponding to the width W1 (see fig. 2) of the outer plate 25 of the chain that can be used in the escalator.
Specifically, in the example shown in fig. 4, the plate member 31 is provided with opposing portions 33 to 40 for forming the cutouts. The opposing portion 33 and the opposing portion 34 oppose each other. The opposing portions 33 and 34 form a slit 41 having a width of the distance L1. The distance L1 is set corresponding to the width W1 of the outer plate 25 of the chain determined by the reference "RS 80". That is, the opposing portions 33 and 34 are provided such that the outer plates 25 of the chain of the RS80 are just embedded therebetween.
The opposing portion 35 and the opposing portion 36 oppose each other. The opposing portions 35 and 36 form a slit 42 having a width of the distance L2. The distance L2 is set corresponding to the width W1 of the outer plate 25 of the chain determined by the reference "RS 60". Distance L2 is smaller than distance L1. In the example shown in fig. 4, the slit 42 opens inside the slit 41.
The opposing portion 37 and the opposing portion 38 are opposed to each other. The opposing portions 37 and 38 form a slit 43 having a width of the distance L3. The distance L3 is set corresponding to the width W1 of the outer plate 25 of the chain determined by the mark "RS 50". Distance L3 is smaller than distance L2. In the example shown in fig. 4, the slit 43 opens inside the slit 42.
The opposing portion 39 and the opposing portion 40 oppose each other. The opposing portions 39 and 40 form a slit 44 having a width of the distance L4. The distance L4 is set corresponding to the width W1 of the outer plate 25 of the chain determined by the mark "RS 40". Distance L4 is smaller than distance L3. In the example shown in fig. 4, the slit 44 opens inside the slit 43.
Further, a through hole 45 is formed in the plate member 31. The string-like member 32 is connected to the plate member 31 using a through hole 45.
Fig. 4 shows an example in which the edge of the opposing portion 34, the edge of the opposing portion 36, the edge of the opposing portion 38, and the edge of the opposing portion 40 are arranged in a straight line. Fig. 5 is a diagram showing another example of the determination tool 30. As in the example shown in fig. 5, the edges of the opposing portions 34, 36, 38, and 40 may not be arranged in a straight line.
Fig. 6 is a diagram for explaining a method of determining the size of a chain using the determining tool 30. The maintenance person holds the determination tool 30 against the chain as shown in fig. 6. Specifically, the maintenance person holds the plate member 31 in a state of hanging the string-like member 32 on the finger or the wrist. Then, the maintenance person brings the plate member 31 into contact with the outer plate 25 of the chain from the side. The maintenance person can determine the size of the chain by finding a cut that fits exactly into the outer plate 25. In the case of the example shown in fig. 6, the maintenance personnel can determine that the chain used is the chain of RS 60.
By using the determination tool 30, a maintenance person can easily determine the size of the chain even when the chain is placed deep in the narrow machine room 4, for example.
In the present embodiment, an example in which four cutouts 41 to 44 are formed in the plate member 31 of the determination tool 30 is described. This is an example. It is also possible to form only two or three cutouts in the plate member 31. Five or more cutouts may be formed in the plate member 31.
Fig. 7 is a diagram showing another example of the determination tool 30. Fig. 8 is a view of the determination tool 30 shown in fig. 7 viewed from the a direction. The determination tool 30 shown in fig. 7 and 8 includes the opposing portions 33 to 40 on the plate member 31, similarly to the example shown in fig. 4. Further, cutouts 41 to 44 are formed in the plate member 31. On the other hand, the determination tool 30 shown in fig. 7 and 8 is different from the example shown in fig. 4 in that the cutouts 41 to 44 are formed independently in the plate member 31.
In the example shown in fig. 7 and 8, the cutouts 41 and 42 are arranged in a lateral arrangement. The slit 41 and the slit 42 open in the same direction. The cutouts 43 and 44 are arranged in a laterally aligned manner. The slit 43 and the slit 44 open in the same direction. The slit 44 opens in a direction opposite to the direction in which the slit 41 opens. The slit 43 opens in a direction opposite to the direction in which the slit 42 opens.
The determination tool 30 shown in fig. 7 and 8 is different from the example shown in fig. 4 in that a folded portion 46 is provided instead of the string-like member 32. The folded portion 46 is provided on the plate member 31. The folded portion 46 is arranged perpendicularly to the plate member 31. The maintenance person holds the fold-back portion 46 and holds the determination tool 30 against the chain. In order to prevent the tool 30 from falling off, the string-like member 32 may be connected to the folded-back portion 46.
Fig. 9 is a diagram for explaining a method of determining the size of a chain using the determining tool 30 shown in fig. 7 and 8. In the case of using the determination tool 30 shown in fig. 7 and 8, the maintenance person may attach the determination tool 30 to the chain in an upright state as shown in fig. 9. In the example shown in fig. 7 and 8, when the determining tool 30 is abutted against the outer plate 25 of the chain, the plate member 31 does not interfere with the outer plate 25 adjacent to the outer plate 25.
Fig. 10 is a diagram showing another example of the determination tool 30. Fig. 10 (a) shows a front view of the determination tool 30. Fig. 10 (b) shows a side view of the determination tool 30. Fig. 10 (c) shows a plan view of the determination tool 30. The determination tool 30 shown in fig. 10 includes a plate member 31 and a plate member 47.
As an example, the plate member 31 and the plate member 47 are each made of an iron plate having a constant thickness. The plate member 47 is provided to the plate member 31. The plate member 47 is arranged perpendicularly to the plate member 31. In the example shown in fig. 10, the plate member 31 and the plate member 47 are integrally formed in an L-shape.
The plate member 31 includes opposing portions 33 and 34 that face each other and opposing portions 39 and 40 that face each other. That is, the plate member 31 is formed with the cutouts 41 and 44. The slit 44 opens in a direction opposite to the direction in which the slit 41 opens.
The plate member 47 includes opposing portions 35 and 36 that face each other and opposing portions 37 and 38 that face each other. That is, the plate member 47 is formed with the cutouts 42 and 43. The slit 43 opens in a direction opposite to the direction in which the slit 42 opens.
Fig. 11 is a diagram for explaining a method of determining the size of a chain using the determining tool 30 shown in fig. 10. In the case of using the determination tool 30 shown in fig. 10, the maintenance person may attach the determination tool 30 to the chain in a state where the plate member 47 is erected as shown in fig. 11. Since the plate member 47 is disposed perpendicularly to the plate member 31, as shown in fig. 11, even if the determination tool 30 is abutted against the outer plate 25 of the chain, the plate member 31 does not interfere with the outer plate 25 adjacent to the outer plate 25. The same applies to the case where the plate member 31 is abutted against the chain.
In the example shown in fig. 10, the plate member 47 may be provided obliquely with respect to the plate member 31. In this case, it is preferable that the plate member 47 is disposed at a position not overlapping the cutouts 41 and 44 when viewed from a direction perpendicular to the plate member 31. It is preferable that the plate member 31 is disposed at a position not overlapping the notch 42 and the notch 43 when viewed from a direction perpendicular to the plate member 47.
