Description

  The present invention relates to passenger conveyors such as escalators and moving walkways for transporting passengers, and more particularly to the structure of the passenger floor.

  An example of the structure of the boarding / alighting floor in the conventional passenger conveyor is demonstrated using FIG. 7, FIG.

  As shown in FIG. 8, the comb plate 14P that supports the back side of the floor cover 14D has a width dimension smaller than the distance between the left and right frames 4 because the balustrade base 17 is located on both sides thereof. ing. For this reason, a support member 16 that extends from the vicinity of the upper surface of the frame body 4 to the vicinity of the upper side of the tread roller 10A is provided separately, and the end of the comb plate 14P is placed on the support member 16. The support member 16 and the frame 4 are fixed by welding, bolts, or the like, and the support member 16 and the comb plate 14P are fixed by bolts 16V or the like.

  Further, the height D1 of the driven side machine section 6 in the conventional passenger conveyor is (the thickness of the comb plate 14P and the floor cover 14D combined) U1 + (distance from the upper end of the support member 16 to the upper surface of the tread roller 10A) F1 + ( Distance from the upper surface of the tread roller 10A to the lower surface of the tread roller 10B) T1 + (gap from the lower surface of the tread roller 10B to the oil receiver 15) G1 + (thickness of the oil receiver 15) Y Note that F1 is also (dimension from the upper surface of the tread roller 10A to the tread surface of the tread plate 10d) H1 + (gap from the lower surface of the comb plate 14P to the tread surface of the tread plate 10d) g1, and G1 is (from the lower surface of the tread roller 10B to the tread plate). It is also the dimension from the tread of the tread plate 10a to the oil receiver 15) g2.

  As an example of the structure of the boarding / alighting floor in such a conventional passenger conveyor, the following Patent Document 1 can be cited.

JP-A-11-171457 (FIG. 2 etc.)

  As described above, in the conventional passenger conveyor, the support member 16 for attaching the comb plate 14P is provided above the tread board roller 10A. Here, since the support member 16 has a cantilever structure, it is necessary to ensure a certain degree of rigidity. As shown in FIG. 7, the cross section has an inverted U shape. Therefore, the height dimension of the support member 16 is a size that cannot be ignored. Actually, the position of the upper surface of the tread board roller 10A must be lower than the position of the tread surface of the tread board 10d by about the dimension H1, As a result, the height dimension of the machine part of the passenger conveyor has increased.

  The objective of this invention is providing the passenger conveyor which suppressed the increase in the height dimension of the machine part accompanying installation of a comb plate.

  In order to achieve the above-described object, in the present invention, a frame body installed in a building structure, a boarding floor provided at both ends in the longitudinal direction of the frame body, and the boarding floor are connected endlessly. A passenger conveyor provided with a railing that circulates and a railing that opposes the direction of movement of the treadle, a balustrade base for supporting the railing by the frame is installed on the frame, The floor was composed of a floor cover, a comb plate and a comb, and the comb plate was supported by the balustrade base.

  ADVANTAGE OF THE INVENTION According to this invention, the passenger conveyor which suppressed the increase in the height dimension of the machine part accompanying installation of a comb plate can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  First, the 1st Embodiment of this invention is described using FIGS. 1-3. FIG. 1 is a diagram showing a schematic structure of an electric road (moving sidewalk) 3 which is a kind of passenger conveyor, as a first embodiment of the present invention. As shown in FIG. 1, the electric road 3 in the present embodiment is provided at a frame body 4 installed in a groove 2 formed by excavating a building structure 1 and at both longitudinal ends of the frame body 4. The boarding / exiting floor 14, the step board 10 connected in an endless manner between the boarding / exiting floors 14, and the balustrade facing each other along the moving direction of the step board 10 are provided. Furthermore, the electric road 3 in the present embodiment includes a moving handrail 12 that circulates in synchronization with the tread board 10, a drive-side mechanical unit 5 formed near one of the landing floors 14, and the other landing floor 14. It has a driven side machine part 6 formed near the lower part. A tread plate chain 9 is wound endlessly between a drive sprocket 7 pivotally supported in the drive side machine part 5 and a driven sprocket 8 pivotally supported in the driven side machine part 6. The drive sprocket 7 is driven by a drive device 13 in the machine unit 5.

  Next, the structure in the vicinity of the driven side mechanical unit 6 will be described in detail with reference to FIG. As shown in FIG. 2, a driven sprocket 8 and the like are arranged in the frame body 4, and the tread 10 is also reversed in synchronization with the tread chain 9 wound around the outer diameter side of the driven sprocket 8. It is configured. The tread board 10 travels, for example, 10a → 10b → 10c → 10d, and the tread board 10 passes above and below the driven sprocket 8. Naturally, the driving direction of the electric road 3 can be reversed, that is, the direction of travel of the tread board 10 can be reversed.

  Moreover, while the passenger descends from the step board 10d on the outward path and proceeds to the building structure 1, a boarding / alighting floor 14 is formed, and the upper part of the portion where the tread board 10 is reversed is blocked. The getting-on / off floor 14 includes floor covers 14A, 14B, and 14D, a comb plate 14P, a comb (comb) 14C, a floor frame 14W, and the like. Here, the comb 14C located on the step board 10d side of the boarding / alighting floor 14 is colored in yellow or the like, and is fixed to the comb plate 14P. The tread plate 10 travels below the comb plate 14P. By forming the comb plate 14P using an iron plate of about 12 mm to 38 mm, not only the interference between the comb plate 14P and the tread plate 10 is avoided, but also the driven side machine It is possible to prevent the portion 6 from becoming deep.

  Further, a floor cover 14D is attached to the upper surface of the comb plate 14P by welding or bonding. As shown in FIG. 3, the width of the floor cover 14 </ b> D is smaller than the width of the comb plate 14 </ b> P, but extends to the outside of the skirt guard 25 and covers the entire width direction of the passenger floor 14. Further, the floor cover 14D is connected to the adjacent floor cover 14A and is formed of the same material as the floor covers 14A and 14B. Etc. can be kept high. The floor covers 14A and 14B are formed of a thin plate so that they can be removed at the time of inspection in the driven side machine unit 6, but are bent to increase rigidity and are higher than the comb plate 14P. The dimensions of are larger. The floor frame 14W has an L-shaped cross section and is arranged around the floor covers 14A, 14B and the like to support the entire getting-on / off floor 14.

  Next, as shown in FIG. 3, the balustrade in this embodiment includes a balustrade panel 11 such as a glass panel, a handrail frame 28 fixed to the periphery thereof, and a moving handrail 12 guided by the handrail frame 28. An inner deck cover 26 and an outer deck cover 27 covering the lower part of the balustrade panel 11, a skirt guard 25 extending downward from the inner deck cover 26, and a balustrade base 17 for supporting them with the frame body 4. Yes. Here, the frame body 4 is composed of left and right vertical frame bodies 4a and 4b, an oil receiver 15 that forms the bottom surface, a bracket for mounting each device, and the like, and a balustrade base 17 is provided on the vertical frame bodies 4a and 4b. It is fixed and supports the balustrade load. The oil receiver 15 is provided to prevent oil dripping from the tread chain 9 or the like from leaking to the outside.

  Further, as shown in FIG. 3, the tread plate 10 is provided on a chain shaft 9A, and a pair of left and right tread plate chains 9 are connected to the chain shaft 9A. Further, a tread plate roller is provided at the tip of the chain shaft 9A. 10A etc. are attached.

  Furthermore, the support method of the comb plate 14P in this embodiment is demonstrated along FIG. In the present embodiment, the support member 16 or the like is installed below the comb plate 14P to support the comb plate 14P from the lower side, but the comb plate 14P is supported from the upper side by the balustrade base 17. Specifically, the suspension members 17a and 17b are provided on the balustrade base 10 side of the balustrade base 17, and the vicinity of the four corners of the comb plate 14P is suspended from the balustrade base 17 by using the suspension members 17a and 17b. Here, the suspension members 17a and 17b have one end fixed to the upper surface of the comb plate 14P with a bolt 16V and the other end fixed to the side surface of the balustrade base 17 with a bolt. In addition, the suspension members 17a and 17b of the present embodiment are provided with the inclined surfaces 17G, so that the operation panel 23 can be easily arranged inside the balustrade. In addition, you may provide notches etc. in the suspension members 17a and 17b instead of the inclined surface 17G.

  According to such a configuration, since the support member 16 and the like that existed below the conventional comb plate 14P are eliminated, the upper surface of the outward tread board roller 10A is lowered to a position lower than the tread surface of the outward tread board 10d. It ’s not necessary. Therefore, in the present embodiment, the upper surface of the tread plate roller 10A is positioned at substantially the same height as the tread surface of the tread plate 10d, that is, the dimension H1 in FIG. At this time, the lower surface of the return path side tread roller 10B is also located at substantially the same height as the tread surface of the return path side tread board 10a, that is, the dimension H2 in FIG. Note that (gap from the tread surface of the return path tread plate 10a to the oil receiver 15) g2 may be the same gap g2 as in FIG.

  As a result, in the present embodiment, the driven sprocket 8 and the return-side tread roller 10B are shifted approximately H1 upward by the amount of the shift of the tread roller 10A upward by approximately H1, and further, the lower surface of the return-path side tread roller 10B and the return-path side Therefore, the height of the driven side machine portion 6 can be reduced by the dimension of H1 + H2 as a whole. Specifically, the height D2 of the driven side machine section 6 of the passenger conveyor in the present embodiment is U1 + g1 + T1 + g2 + Y as shown in FIG. 3, and is smaller than the conventional height D1. If the diameter TG1 of the driven sprocket 8 is reduced, the driven machine part 6 can be further reduced in thickness. Further, in the present embodiment, the example of the driven side machine unit 6 has been described, but the same applies to the drive side machine unit 5 as well.

  Next, a second embodiment of the present invention will be described based on the electric road 3 shown in FIGS. Also in the present embodiment, the configuration of the frame body 4, the driven sprocket 8, the tread board 10, the balustrade and the like is the same as that of the above-described embodiment, and therefore, the configuration different from the above-described embodiment will be described below.

  In the present embodiment, as shown in FIG. 4, the anti-comb 14C side (arrow A side in FIG. 4) of the comb plate 14P is supported by the balustrade base 17, and the comb plate 14P uses the anti-comb 14C side as a fulcrum. The side can be displaced upward. Then, an abnormality occurring in the comb 14C is detected by sensing the upward displacement on the comb 14C side with the switch 22.

  Specifically, first, the anti-com 14C side of the comb plate 14P will be described with reference to FIG. 5 which is a cross-sectional view taken along line III-III in FIG. As shown in FIG. 5, the concave portion 17CC of the suspension member 17c provided on the side of the balustrade base 17 and the convex portion 18A of the convex bracket 18 provided on the comb plate 14P are engaged and fixed by a pin 19. The engaging portion 18S has a structure that suppresses movement in the width direction, and can rotate only in the longitudinal direction.

  On the other hand, the comb plate 14P side of the comb 14C will be described with reference to FIG. 6 which is a cross-sectional view taken along IV-IV in FIG. As shown in FIG. 6, a jack plate 20 is provided that extends from the vicinity of the upper surface of both end portions of the comb plate 14 </ b> P to the vicinity of the upper portion of the frame body 4. One end of the comb plate 14P is fixed to the upper surface of the comb plate 14P, and the other end is supported by the jack bolt 21. Although the jack bolt 21 is supported on the frame body 4, the movement of the comb plate 14P in the width direction is suppressed by the engaging portion 18S on the anti-comb 14C side. Even if it is not completely fixed just by placing it on 4, it will not slip.

  According to such a configuration, the comb 14C side of the comb plate 14P can be displaced only upward, and if the switch 22 is provided above the comb 14C side of the comb plate 14P, abnormal force is applied to the comb C for some reason. When added, the upward movement of the comb plate 14P can be sensed to detect an abnormality occurring in the comb 14C. Therefore, even if a foreign object or the like sandwiched between adjacent treads 10 collides with the comb 14C, the operation of the electric road 3 can be stopped immediately before the comb 14C or a part of the tread 10 is broken.

  In the present embodiment, although the jack plate 20 is provided, since it is provided on the upper side rather than the lower side of the comb plate 14P, the position of the upper surface of the tread plate roller 10A is substantially the same as the position of the tread surface of the tread plate 10d. It can be maintained at the same height. Therefore, as in the first embodiment, it is possible to provide the electric road 3 in which the machine part is thinned. In addition, if the balustrade base 17 and the building structure 1 are fixed with the connection tool 24, the balustrade base 17 can be prevented from falling down, and the rigidity of the entire electric road 3 can be increased.

  In addition, although the above-mentioned embodiment demonstrated the electrically-driven road 3 in which a level | step difference does not arise between the treads 10, the same structure is employable also about the escalator which is a kind of passenger conveyor. Therefore, the term “tread” used in the present specification includes the meaning of a step having a step.
