Description

Passenger conveying equipment

Technical Field

The present invention relates to a passenger conveyor such as an escalator or a moving walkway for transporting passengers, and more particularly to a structure of a floor of an entrance/exit of the passenger conveyor.

Background

The structure of the entrance and exit floors of the passenger conveyor in the related art will be described below by way of example with reference to fig. 7 and 8.

As shown in fig. 8, the comb plate 14P supporting the back surface side of the floor cover 14D has a width smaller than the distance between the left and right frames 4 because the balustrade bases 17 are provided on both sides thereof. For this purpose, a support member 16 extending from the vicinity of the upper surface of the frame 4 to the vicinity of the upper side of the pedal roller 10A is additionally provided to the comb plate 14P, and the end of the comb plate 14P is provided to the support member 16. Further, 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.

In the conventional passenger conveyor, the height D1 of the driven-side mechanism section 6 is equal to (the total thickness of the comb plate 14P and the floor cover 14D) U1+ (the distance from the upper end of the support member 16 to the upper surface of the pedal roller 10A) F1+ (the distance from the upper surface of the pedal roller 10A to the lower surface of the pedal roller 10B) T1+ (the gap from the lower surface of the pedal roller 10B to the oil reservoir 15) G1+ (the thickness of the oil reservoir 15) Y. F1 is equal to (the dimension from the upper surface of pedal roller 10A to the tread surface of pedal 10 d) H1+ (the gap from the lower surface of comb plate 14P to the tread surface of pedal 10 d) G1, and G1 is equal to (the dimension from the lower surface of pedal roller 10B to the tread surface of pedal 10A) H2+ (the gap from the tread surface of pedal 10A to oil reservoir 15) G2.

For example, patent document 1 and the like below disclose a device that employs the floor structure for the upper and lower openings of the conventional passenger conveyor described above.

Patent document 1 Japanese patent laid-open No. Hei 11-171457 (FIG. 2, etc.)

As described above, in the conventional passenger conveyor, the support member 16 for mounting the comb plate 14P is provided above the step roller 10A. Since the support member 16 has a cantilever structure, it is necessary to secure a certain rigidity, and therefore, as shown in fig. 7, the cross section of the support member 16 is formed in an inverted U shape. Therefore, the height of the support member 16 is greatly increased to a level that cannot be ignored, and in practice, the position of the upper surface of the pedal roller 10A has to be set lower than the position of the tread surface of the pedal 10d by a dimension H1, which results in an increase in the height of the mechanical part of the passenger conveyor.

Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

First, embodiment 1 of the present invention will be described with reference to fig. 1 to 3. Fig. 1 is a schematic configuration diagram showing a power lane (moving lane) 3 which is one of passenger conveyors according to embodiment 1 of the present invention. As shown in fig. 1, the electromotive force tunnel 3 in the present embodiment includes: a frame 4, the frame 4 being provided in a groove 2 formed by excavating the building 1; upper and lower floor plates 14 provided at both end portions in the longitudinal direction of the frame 4; a step plate 10 connected in a ring shape between the upper and lower floor plates 14 and moving cyclically; and rails facing each other along the moving direction of the steps 10. The electric tunnel 3 of the present embodiment further includes a moving handrail 12 that moves cyclically in synchronization with the steps 10; a drive-side mechanical portion 5 formed in the vicinity below the one-side upper and lower port floor 14; and a driven side mechanical part 6 formed in the vicinity below the upper and lower port floor 14 on the other side. The pedal chain 9 is looped around the drive sprocket 7 pivotally supported in the drive side machine part 5 and the driven sprocket 8 pivotally supported in the driven side machine part 6, and the drive sprocket 7 is driven by the drive device 13 in the drive side machine part 5.

The structure in the vicinity of the driven-side mechanical portion 6 will be described in detail below with reference to fig. 2. As shown in fig. 2, a driven sprocket 8 and the like are provided in the housing 4, and the pedals 10 are reversed in synchronization with the pedal chain 9 wound around the outer diameter side of the driven sprocket 8. The pedal 10 travels, for example, in a manner of 10a → 10b → 10c → 10d, and passes through the upper and lower sides of the driven sprocket 8. Furthermore, it is naturally also possible to switch the direction of travel of the power tunnel 3 to the opposite direction, that is to say to enable the pedal 10 to travel in the opposite direction to that described above.

Further, a floor 14 for covering the upper side of a portion where the passenger gets on and off the step 10d on the forward side to enter the building 1 is formed. The floor panel 14 includes floor panel covers 14A, 14B, 14C, and 14D, comb plates 14P, comb bars (comb teeth) 14C, and a floor frame 14W. Here, the comb teeth 14C on the step plate 10d side of the upper and lower floor plates 14 are colored yellow or the like, and are fixed to the comb plate 14P. Although the step plate 10 travels under this comb plate 14P, since the comb plate 14P is formed by a steel plate of about 12mm to 38mm, it is not only possible to avoid interference between the comb plate 14P and the step plate 10, but also it is not necessary to deepen the depth of the driven side mechanical part 6.

In addition, a floor surface cover 14D is mounted on the upper surface of the comb plate 14P by welding, adhesion, or the like. As shown in fig. 3, the width of the floor surface cover 14D is smaller than the width of the comb plate 14P, but it extends to the outside of the apron panel 25 to cover the entire width of the floor 14. Further, since the floor surface covering plate 14D is connected to the adjacent floor surface covering plate 14A and is made of the same material as the floor surface covering plates 14A and 14B, the appearance, the anti-slip function, and the like can be maintained well over the entire surface of the floor panel 14. In order to remove the floor surface covers 14A and 14B when the inside of the driven-side machine part 6 is inspected, the floor surface covers 14A and 14B are made of thin plates, and the floor surface covers are bent to increase the rigidity, so that the dimension in the height direction thereof is larger than the comb plate 14P. The floor frame 14W has an L-shaped cross section, is provided around the floor surface covers 14A and 14B, and supports the entire upper and lower floor boards 14.

As shown in fig. 3, the balustrade in the present embodiment has: a balustrade panel 11 such as a glass panel; a handrail frame 28 fixed to the periphery of the balustrade panel; a moving handrail 12 guided by the handrail frame 28; an inner side guard plate 26 and an outer side guard plate 27 covering the lower part of the balustrade panel 11; a skirt 25 extending downward from the inner panel 26; and a railing base 17 and the like for supporting the above members by the frame 4. The frame 4 is composed of left and right vertical frames 4a and 4b, an oil reservoir 15 forming the bottom surface of the frame, a bracket for mounting various devices, and the like, and a handrail base 17 is fixed to the vertical frames 4a and 4b to support the load of the handrail. The oil reservoir 15 is provided to prevent oil dripping from the step chain 9 and the like from leaking to the outside.

As shown in fig. 3, the pedals 10 are provided on a chain shaft 9A, the chain shaft 9A is connected to a pair of left and right pedal chains 9, and pedal rollers 10A and the like are attached to the front ends of the chain shafts 9A.

A method of supporting comb plate 14P in the present embodiment will be described below with reference to fig. 3. In the present embodiment, the comb plate 14P is supported from the upper side by the rail base 17, instead of providing the support member 16 or the like below the comb plate 14P to support the comb plate 14P from the lower side. Specifically, suspension members 17a and 17b are provided on the tread 10 side of the railing base 17, and the comb plate 14P is suspended from the railing base 17 at positions near the four corners by the suspension members 17a and 17 b. One end of each of the suspension members 17a and 17b is fixed to the upper surface of the comb plate 14P by a bolt 16V, and the other end is fixed to the side surface of the rail base 17 by a bolt. Further, since the hanging members 17a and 17b of the present embodiment are provided with the inclined surfaces 17G, the operation panel 23 can be easily provided inside the balustrade. Instead of the inclined surface 17G, notches or the like may be provided in the suspension members 17a and 17 b.

According to the above configuration, since the support member 16 and the like provided below the comb plate 14P in the related art are eliminated, it is not necessary to lower the upper surface of the step roller 10A on the forward side to a position lower than the tread surface of the step 10d on the forward side. In the present embodiment, the height of the upper surface of the pedal roller 10A is set to be substantially the same as the height of the tread surface of the pedal 10d, that is, the dimension H1 in the conventional technique shown in fig. 8 can be reduced to substantially 0 mm. At this time, the height of the lower surface of the step roller 10B on the return side is also substantially the same as the height of the step surface of the step 10a on the return side, that is, the dimension H2 in the conventional technique shown in fig. 8 is substantially 0 mm. The gap g2 from the step surface of the step plate 10a on the return side to the oil reservoir 15 may be the same as the gap g2 in the conventional technique shown in fig. 8.

As a result, in the present embodiment, since the pedal roller 10A is moved substantially upward by H1, the driven sprocket 8 and the pedal roller 10B on the return side are also moved substantially upward by H1, and the deviation between the lower surface of the pedal roller 10B on the return side and the tread surface of the pedal 10A on the return side, which is substantially equal to the height H2, is eliminated, so that the thickness dimension of the driven-side machine part 6 can be reduced by about H1+ H2 as a whole. Specifically, the height D2 of the driven side mechanical portion 6 of the passenger conveyor in the present embodiment, as shown in fig. 3, is equal to U1+ g1+ T1+ g2+ Y, which is smaller than the height D1 in the related art. Further, if the diameter TG1 of the driven sprocket 8 is reduced, the driven side mechanical part 6 can be further thinned. In the present embodiment, the driven-side machine part 6 is described as an example, but the present invention is also applicable to the driving-side machine part 5.

Embodiment 2 of the present invention will be described below with reference to the power running lane 3 shown in fig. 4 to 6. In the present embodiment, the configurations of the frame 4, the driven bracket 8, the step panel 10, the balustrade, and the like are the same as those of the above-described embodiment, and therefore, the following description will be mainly made on the configurations different from the above-described embodiment.

In the present embodiment, as shown in fig. 4, the comb plate 14P is supported by the rail base 17 on the side opposite to the comb rack 14C (arrow a side in fig. 4), and the comb plate 14P is configured to be displaceable upward with the side opposite to the comb rack 14C side as a fulcrum. Then, the switch 22 detects the upward displacement of the comb-teeth bar 14C side, thereby detecting an abnormality occurring in the comb-teeth bar 14C.

Hereinafter, first, a side of the comb plate 14P opposite to the comb rack 14C will be specifically described with reference to fig. 5 which is a sectional view at III-III of fig. 4. As shown in fig. 5, the recess 17CC of the hanging member 17c provided on the side portion of the balustrade base 17 is engaged with the boss 18A of the boss bracket 18 provided on the comb plate 14P, and is fixed by the pin 19. The engaging portion 18S is a structure for suppressing the movement in the width direction, and is rotatable only in the longitudinal direction.

On the other hand, the comb-rack-bar 14C side of the comb plate 14P is explained with reference to fig. 6 which is a sectional view at IV-IV of fig. 4. As shown in fig. 6, a packing plate (packing plate)20 is provided to extend from the vicinity of the upper surface of both side end portions of the comb plate 14P toward the vicinity of the upper side of the frame 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 a supporting bolt (bolting bolt) 21. Further, since the support bolt 21 is supported above the frame 4 and the movement of the comb plate 14P in the width direction is suppressed by the engaging portion 18S on the side opposite to the comb rack 14C, the support bolt 21 is simply placed on the frame 4 and does not displace even if it is not completely fixed.

According to the above configuration, since the comb-rack 14C side of the comb plate 14P is provided so as to be displaceable only upward, by providing the switch 22 above the comb-rack 14C side of the comb plate 14P, when an abnormal force acts on the comb-rack 14C due to some cause, upward movement of the comb plate 14P is detected, and it is possible to detect that an abnormality has occurred in the comb-rack 14C. Therefore, when foreign matter or the like sandwiched between the adjacent steps 10 collides with the comb-teeth strips 14C, the operation of the electric path 3 can be stopped immediately before the comb-teeth strips 14C and a part of the steps 10 or the like are broken.

In the present embodiment, although the tie plate 20 is provided, since the tie plate is provided on the upper side of the comb plate 14P, not on the lower side, the height of the position of the upper surface of the pedal roller 10A can be maintained at substantially the same height as the position of the tread surface of the pedal 10 d. Therefore, as in embodiment 1, the power feed passage 3 having a mechanical portion reduced in thickness can be provided. Further, by fixing the balustrade base 17 and the building 1 by the connector 24, the balustrade base 17 can be prevented from collapsing, and the rigidity of the entire electric passageway 3 can be improved.

In the above-described embodiment, the electric path 3 in which no step difference occurs between the steps 10 has been described as an example, but an escalator, which is one of the passenger conveyor apparatuses, can also be configured similarly. Therefore, the term "step" used in this specification also includes steps that cause a step.
