  FIG. 1 is a diagram illustrating a configuration of the escalator 10. The escalator 10 is a device that moves the passenger 4 between the landing floor 6 and the landing floor 8 having a height difference. The escalator 10 includes a step 12 in which passengers 4 ride, a step chain 14 to which each step 12 is connected, a main drive device 16 that drives the step chain 14, a handrail 70 and a support portion 30. And a nylon guide 200 and a handrail driving device 140 that drives the moving handrail 70. The handrail driving device 140 is configured to include the driving roller 100 and the pressure roller 120, and detailed description thereof will be described later.

  Step 12 has a size that allows passengers 4 to carry one or two passengers. When the escalator 10 operates, the plurality of steps 12 move while maintaining a horizontal state with respect to the ground. Step 12 is provided with a plurality of grooves for preventing slipping.

  The step chain 14 connects the respective steps 12 via appropriate shaft members (not shown), and transmits the driving force of the main drive device 16 to the respective steps 12. Further, one step chain 14 is disposed on each of the left and right sides of the step 12 of the escalator 10.

  The main drive device 16 is a device that outputs a driving force for driving the escalator 10, and is composed of, for example, an electric motor and a reduction gear. The driving force output by the main driving device 16 is transmitted to the driving roller 100 via a step chain 14 and a moving handrail chain (not shown) via a driving transmission means (not shown).

  The balustrade section 20 includes an endless moving handrail 70 and a support section 30 that prevents the body of the passenger 4 from going out of the escalator 10 when the step 12 moves. The moving handrail 70 is a portion where the passenger 4 attaches or holds a hand, and the support portion 30 has a function of guiding the moving handrail 70. The support portion 30 includes a moving handrail guide rail 42 and an inner plate 32. The moving handrail guide rail 42 has an end portion that is interrupted in the vicinity of both ends of the driving roller 100.

  Here, the configuration of the relationship between the moving handrail 70 and the support portion 30 will be described in detail. FIG. 2 shows a relationship between the moving handrail 70 and the support portion 30 corresponding to a sectional view perpendicular to the traveling direction of the moving handrail 70 in FIG. The moving handrail 70 includes a steel core 64 that is an interlining, a canvas laminated portion 68 that covers the periphery thereof, and a surface layer portion 66 that is disposed on the outside thereof. As the material of the surface layer portion 66, a material that is easy to touch, such as raw rubber, can be used. For example, a canvas can be used for the canvas laminate portion 68 in order to ensure an appropriate strength.

  The moving handrail guide rail 42 is disposed inside the moving handrail 70 having a substantially C-shaped cross section, and has an outer shape that is substantially the same shape as the inner side surface shape of the moving handrail 70. Further, the outer peripheral surface of the moving handrail guide rail 42 comes into contact with the inner surface of the moving handrail 70, so that the moving handrail 70 is guided so as not to remove the course when sliding.

  Since the inner plate 32 constitutes both side surfaces of the escalator 10, for example, a glass panel or stainless steel is used as a material in order to ensure a decorative viewpoint and appropriate strength. The moving handrail guide rail 42 and the inner plate 32 are connected using a connecting member such as a bolt.

  Returning to FIG. 1 again, the handrail drive device 140 will be described. The handrail driving device 140 has a function of driving the moving handrail 70 as described above, and includes the driving roller 100 and the pressure roller 120.

  In the handrail driving device 140, a plurality of pressure rollers 120 are disposed at positions facing the plurality of driving rollers 100 with the moving handrail 70 interposed therebetween. One pressure roller 120 that constitutes the plurality of pressure rollers 120 is aligned with one drive roller 100 that constitutes the plurality of drive rollers 100. The driving roller 100 is driven by the driving force output from the main driving device 16, and the pressure roller 120 presses the moving handrail 70 toward the corresponding driving roller 100 by a pressing means (not shown). It rotates according to the driving of the driving roller 100.

  The moving handrail 70 is disposed in an endless manner, and on the return path side of the moving handrail 70, the driving roller 100 rotates in the direction of arrow D, so that the moving handrail 70 sandwiched between the pressure roller 120 is shown in FIG. Move in the direction of arrow C.

  FIG. 3 shows a relationship between the driving roller 100 and the pressure roller 120 corresponding to a sectional view perpendicular to the moving direction of the moving handrail 70 in FIG. 1, that is, a sectional view taken along the line BB. The driving roller 100 and the pressure roller 120 are made of, for example, urethane. The driving roller 100 is disposed along the moving handrail 70, and the pressure roller 120 is disposed opposite to the driving roller 100 with the moving handrail 70 interposed therebetween in the width direction of the moving handrail 70 indicated by W in FIG. Is done.

  FIG. 4 is an enlarged view of the region indicated by the alternate long and short dash line E in FIG. FIG. 5 is a perspective view showing a state in which the driving roller 100 and the pressure roller 120 are removed from FIG. The nylon guide 200 is attached to the end portion 42 a of the moving handrail guide rail 42 in a gap 77 formed between the driving roller 100 and the end portion 42 a of the moving handrail guide rail 42. A similar nylon guide 200 (see FIG. 1) is also attached to the other end portion of the moving handrail guide rail 42, but here it is provided at the one end portion 42a using FIGS. A nylon guide 200 will be described.

  The nylon guide 200 includes a flat portion 202 that is flattened over substantially the entire upper surface, and an attachment portion 206 for attaching the nylon guide 200 to the moving handrail guide rail 42. The plane portion 202 has a box shape having a width X that is substantially the same as the width of the moving handrail guide rail 42 and a height Y that is substantially the same as both ends of the moving handrail guide rail 42. The flat surface portion 202 has a length Z that is a little shorter than the length R of the gap between the driving roller 100 and the end portion 42 a of the moving handrail guide rail 42. In addition, the front side end surface 203 and the back side end surface 204 of the plane part 202 are rounded end surfaces, respectively.

  The attachment portion 206 is a member that extends from the end portion of the upper surface of the flat portion 202 toward the moving handrail guide rail 42. Further, the front side end surface 205 and the back side end surface 209 constituting the side surface of the mounting portion 206 are respectively slightly rounded end surfaces. The nylon guide 200 can be attached to the moving handrail guide rail 42 by tightening the bolt 208 through the hole 207 with respect to the screw hole provided in the moving handrail guide rail 42. Further, the hole 207 has a substantially elliptical shape in which the diameter along the width X direction is larger than the diameter along the length Z direction, and the bolt 208 is loosened so that the plane portion 202 is made in the width X direction (in other words, It is possible to slide along the width W direction of the moving handrail 70. Here, the nylon guide 200 includes a synthetic fiber in order to ensure an appropriate strength. The nylon guide 200 and the bolt 208 provided on the upper portion of the nylon guide 200 are collectively referred to as a terminal guide.

  Here, the nylon guide 200 is attached to the moving handrail guide rail 42 against the tension of the endless moving handrail 70, and the moving handrail 70 slides with respect to the nylon guide 200. The front end surface 203 of the nylon guide 200 may be scraped by friction between the inner surface of the nylon guide 200 and the front end surface 203 of the nylon guide 200. Therefore, in the state in which the front side end surface 203 of the nylon guide 200 is cut, a portion of the endless moving handrail 70 corresponding to the front side end surface 203 of the nylon guide 200 is shifted from the other portion and is located on the back side. However, since the moving handrail 70 slides with respect to the driving roller 100, the driving roller 100 may be damaged.

  FIG. 6 is a view showing the escalator jig 50. The escalator jig 50 is a jig for moving the nylon guide 200 to the near side when the front end face 203 of the nylon guide 200 has been cut as described above. The escalator jig 50 includes a main body portion 54, a first extending portion 52, and a second extending portion 55 having an engaging portion 56.

The main body 54 is a rod member having a length L ₁ that is at least twice as long as the width X of the nylon guide 200 and having a square cross-sectional shape (cross-sectional area S = L ₀ × L ₀ ). . The main body portion 54 is configured to include, for example, stainless steel because appropriate strength is required.

The first extending portion 52 is a bar member that extends in the direction of arrow J from one end portion of the main body portion 54 and has a length L ₂ that is three times longer than the height Y of the planar portion 202. is there. Here, the sectional shape of the first extending portion 52 is a square is the same as the cross-sectional shape of the body portion 54 (cross-sectional area _{S = L 0 × L 0)} . The first extending portion 52 has a flat plate portion 52a for applying an external force by a metal hammer 9 (see FIG. 7) or the like.

The second extending portion 55 is a bar member that extends in the direction of arrow K from the other end of the main body portion 54 and has a length L ₃ that is three times or more the height Y of the flat surface portion 202. is there. Here, the cross-sectional shape of the second extending portion 55 is the same as the cross-sectional shape of the main body portion 54 and is a square (cross-sectional area S = L ₀ × L ₀ ). The second extending portion 55 has an engaging portion 56 that engages with the back end surface 209 of the nylon guide 200. The engaging portion 56 is provided on the near side (see FIG. 7) of the second extending portion 55 and has a concave portion that is shaped along the outer shape of the back end surface 209 of the nylon guide 200.

  The operation of the escalator jig 50 configured as described above will be described with reference to FIGS. FIG. 7 is a diagram showing a state in which the escalator jig 50 is used to move the nylon guide 200 to the front side. When the escalator 10 is used for a long time, the front end face 203 of the nylon guide 200 is scraped by the sliding of the moving handrail 70 with respect to the nylon guide 200. And the moving handrail 70 will shift | deviate to the back | inner side as much as the front side end surface 203 of the nylon guide 200 was shaved.

  Here, the maintenance worker of the escalator 10 engages the engaging portion 56 with the back end surface 209 of the nylon guide 200. Then, after loosening the bolt 208 provided on the upper portion of the nylon guide 200, an external force toward the front side is applied to the first extending portion 52 by hitting the flat plate portion 52a with a necessary force using a hammer 9 or the like. Thereby, the nylon guide 200 can be moved to the near side. Therefore, according to the escalator jig 50, the escalator 10 is installed in a place where the clearance between the back side of the nylon guide 200 and the building wall, for example, is small and the work space for maintenance is narrowed. Even in this case, the nylon guide 200 can be suitably moved to the near side.

  Next, an escalator jig 51 which is a first modification of the escalator jig 50 will be described. FIG. 8 is a view showing the escalator jig 51. Since the difference between the escalator jig 51 and the escalator jig 50 is only the pressing portion 53, the difference will be mainly described.

The pressing portion 53 is a bar member that extends from an end portion on one side of the main body portion 54 in the direction of arrow P (in other words, the longitudinal direction of the main body portion 54). Here, the pressing portion 53 has the same cross-sectional shape as the main body portion 54, and is a square (cross-sectional area S = L ₀ × L ₀ ). The front end portion 53 a of the pressing portion 53 has a concave portion that is shaped along the outer shape of the front end surface 205 of the nylon guide 200.

  Next, the operation of the escalator jig 51 will be described with reference to FIG. Similarly to the escalator jig 50, the escalator jig 51 also has an engaging portion 56 and a first extending portion 52. Therefore, when the front end face 203 of the nylon guide 200 is scraped, the nylon guide 200 is preferably used. It can be moved to the front side. Here, when the maintenance worker moves the nylon guide 200 toward the front side, for example, if the nylon guide 200 is moved too far toward the front side, the nylon guide 200 is moved backward to make the fine adjustment. Sometimes you want to. In this case, according to the escalator jig 51, the front end portion 53a of the pressing portion 53 is fitted into the front side end surface 205 of the nylon guide 200, and the flat plate portion 55a of the second extending portion 55 is inserted with the hammer 9 (see FIG. 7). By hitting (in other words, by applying an external force in the back side direction), the nylon guide 200 can be moved to the back side, so that the position of the nylon guide 200 can be finely adjusted.

  Next, an escalator jig 60 that is a second modification of the escalator jig 50 will be described. FIG. 9A is a diagram illustrating a configuration of the escalator jig 60. FIG. 9B is a diagram showing a state where the escalator jig 60 is viewed from the direction of the arrow G. Since the difference between the escalator jig 60 and the escalator jig 50 is only the second extending portion 65 having the engaging portion 66, the difference will be mainly described.

  The second extending portion 65 is a member having an engaging portion 66 that extends from the other end portion of the main body portion 54 along the arrow Q direction and further tapers toward the tip portion. Therefore, the engaging portion 66 of the second extending portion 65 can be engaged with the back end surface 209 of the nylon guide 200 by line contact.

  Next, the operation of the escalator jig 60 will be described with reference to FIGS. When the escalator 10 is used for a long time, as described above, the front end face 203 of the nylon guide 200 is scraped, and thus the moving handrail 70 may be shifted to the back side.

  Here, the maintenance worker of the escalator 10 engages the engaging portion 66 with the back end surface 209 of the nylon guide 200 by line contact. Further, after loosening the bolt 208 provided on the upper portion of the nylon guide 200, the flat plate portion 52a is hit with a necessary force using a hammer 9 (see FIG. 7), whereby the front side direction with respect to the first extending portion 52 is obtained. Give external force toward Thereby, the nylon guide 200 can be moved to the near side. Therefore, according to the escalator jig 60, even when the escalator 10 is installed in a place where the clearance between the back side of the nylon guide 200 and the building wall or the like is small and the work space becomes narrow, The nylon guide 200 can be preferably moved to the near side. Further, since the engaging portion 66 of the escalator jig 60 is in line contact with the back end surface 209 of the nylon guide 200, even when the flat plate portion 52a is hit with the hammer 9, it is in surface contact. The nylon guide 200 can be moved to the near side more suitably.

  The engaging portion 66 of the escalator jig 60 has been described as having a tapered shape so as to be in line contact with the back end surface 209 of the nylon guide 200 as shown in FIG. 9B. 9 (c), it may have a tapered engaging portion 67 that makes point contact with the back end surface 209 of the nylon guide 200. In this case, since the contact area between the engaging portion 67 and the back end surface 209 of the nylon guide 200 is further reduced, even when the flat plate portion 52a is hit with the hammer 9, it is slippery compared to the case where the surface contact is made. It is difficult to move the nylon guide 200 to the near side more preferably.
