Abstract
The invention provides a passenger transport device which can reduce high size of a middle part of a frame without designing a pedal structure including a wheel into specific structure. In middle parts (4C, 4D, 4E, 4c) along length direction of the frame (4), a down part of a beam (14) opposite to pedals in return path side forms concave parts (21, 22, 23), and one part of the pedal in backhaul side steps through the concave part. Stepped trace of the pedal in return path side closes to stepped trace of the pedal in go path according with the structure, thus, high size of the middle part of the frame can be reduced without designing a pedal structure including a wheel into specific structure.
Description
Technical Field
The present invention relates to a passenger conveyor for an escalator in which a plurality of steps for conveying passengers form a step in an inclined area and a motor tunnel in which no step is formed between adjacent steps, and more particularly, to a passenger conveyor which can be suitably installed in a staircase or a tunnel.
Background
In general, when the passenger conveyor is installed in a staircase, a passageway, or the like, it is preferable to reduce the height of the frame as much as possible in order to minimize the excavation amount of the steps, the passageway, or the like. For this reason, for example, japanese patent application laid-open No. 2001-10775 of patent document 1 discloses a passenger conveyor that changes traveling positions on the forward side and the return side of a rear wheel pivotally supported by a pedal so that the rear wheel traveling on the forward side and the return side is repeated in the vertical direction. With the above configuration, even when the pedals approach each other in the downward direction, the rear wheel of the forward-side pedal does not interfere with the rear wheel of the return-side pedal, and therefore, the height of the frame can be reduced.

Detailed Description
A first embodiment of the passenger conveyor of the present invention will be described below with reference to the escalator shown in fig. 1 and 2.
The escalator 1 is mainly composed of a frame 4 provided across an upper floor 2 and a lower floor 3, a plurality of steps 5 circulating in the frame 4, a pair of left and right balustrades 6 provided upright on both sides of the frame 4 in the traveling direction of the steps 5, and a moving handrail 7 moving in synchronization with the moving speed of the steps 5 under the guidance of the circumferential edge of the balustrade 6.
The frame 4 includes: an upper machine room region 4A in which an upper machine room 10 for installing a driving device 8, a driving sprocket 9, and the like is provided and a lower machine room region 4B in which a lower machine room 12 for installing a driven sprocket 11, a step cleaning device, and the like, not shown, is provided are formed at both end portions in the longitudinal direction, an intermediate region 4C is formed between the upper machine room region 4A and the lower machine room region 4B, and a forward path and a backward path of the step 5 are formed in the intermediate region 4C. Further, the frame 4 includes, in cross section, a pair of left and right side frames 13, a cross member 14 connecting the left and right side frames 13, and a bottom plate 15 covering lower end portions of the left and right side frames 13 and having an oil pan 15A inside. The side frame 13 has: an upper chord member 13A extending in the longitudinal direction of the frame 4, a lower chord member 13B provided below the upper chord member 13A and spaced apart from the upper chord member by a predetermined distance, and a longitudinal member 13C connecting the upper chord member 13A and the lower chord member 13B. In addition, access floors 16A and 16B flush with the upper floor 2 and the lower floor 3 are provided in the upper machine room region 4A and the lower machine room region 4B.
The steps 5 have steps on which passengers stand, and front wheels 5A and rear wheels 5B are pivotally supported in front and rear of the forward direction. The axle of the front wheel 5A is connected by an endless chain 17, the chain 17 is looped around the drive sprocket 9 and the driven sprocket 11, and the drive sprocket 9 is driven by the drive device 8, so that the pedals 5 are circularly moved.
The front wheels 5A and the rear wheels 5B of the steps 5 travel along a forward-side front wheel rail 18A and a forward-side rear wheel rail 19A that are provided on the forward side and form a travel path of the steps 5, and a return-side front wheel rail 18B and a return-side rear wheel rail 19B that are provided on the return side and form a travel path of the steps 5.
On the forward side, the forward front wheel rail 18A and the forward rear wheel rail 19A are formed of an integrally molded product, and are supported on the side of the side frame 13 of the cross member 14. On the other hand, on the return side, a return-side front-wheel rail 18B and a return-side rear-wheel rail 19B are formed separately and supported on the longitudinal members 13C by respective brackets 20A, 20B.
The escalator 1 is generally configured as described above, but in the present embodiment, concave grooves (recesses) 21 and 22 are further provided in the cross member 14 at positions corresponding to the return side steps 5.
The following is a detailed description. As shown in fig. 2, since the return-side step 5B travels at the uppermost position of the rear wheel 5B with respect to the forward-side step 5a, the rear wheel 5B is closest to the cross member 14. On the other hand, the cross member 14 connects the left and right side frames 13 to prevent them from collapsing, and receives the forward step 5a that travels on the forward front wheel rail 18A and the forward rear wheel rail 19A, and the load of the passenger. For this purpose, the cross member 14 of the present embodiment uses a section bar having an L-shaped cross section, which is composed of a horizontal member 14A and a vertical member 14B, wherein the horizontal member 14A is a collapse prevention member having strength capable of preventing the left and right side frames 13 from collapsing, and the vertical member 14B is a load bearing member having strength capable of bearing the load of the forward side step 5 a. However, in order to obtain the strength required for preventing the side frames 13 from collapsing, it is not necessary to use the cross member 14 as a profile having an L-shaped cross section over the entire length, and it is sufficient to use a horizontal member (collapse prevention member) 14A having a small cross section. Therefore, the portions of the cross member 14 that support the outbound-side steps 5a, the loads of passengers, and the like are L-shaped in cross section, which are formed of horizontal members (anti-collapse members) 14A and vertical members (load bearing members) 14B, and are supported on the longitudinal members 13C of the side frames 13 in a cantilever fashion, while the other portions are formed with respective grooves 21 on the vertical members 14B in order to make the left and right rear wheels 5B of the return-side steps 5B as close as possible to the horizontal members 14A while ensuring a minimum safety clearance C2 with the horizontal members 14A, since the strength required to prevent the side frames 13 from collapsing can be sufficiently ensured by only the horizontal members 14A (anti-collapse members). Further, in order to avoid interference caused by the return side step 5B approaching the cross member 14 after the formation of the grooves 21, grooves 22 are also formed by cutting in the vertical members 14B between the left and right grooves 21.
By forming the cross member 14 as described above, the return side steps 5B can be made to run through the vertical members 14B of the cross member 14 when viewed from the side, that is, a part of the running direction cross section of the steps 5B can be made to run in the grooves 21 and 22, and as a result, the height dimension H2 of the intermediate region 4C of the frame 4 can be made smaller than the current height dimension H1. That is, the height H2 of the frame 4 is equal to the sum of the clearance C1 from the top of the frame 4 to the top of the forward-side step 5A, the height H1 from the top of the forward-side step 5A to the top of the cross member 14, the thickness t of the horizontal member 14A of the cross member 14, the safety clearance C2 between the lower part of the horizontal member 14A and the rear wheel 5B of the return-side step 5B, the height H3 from the top of the rear wheel 5B of the return-side step 5B to the lower part of the step 5B, the safety clearance C3 between the lower part of the step 5B and the reservoir 15A, and the height H4 of the reservoir 15A and the bottom plate 15. In other words, height dimension H2 reduces dimension H of rear wheel 5B of return side step 5B into groove 21 while securing safety clearance C2, as compared to present height dimension H10That is, height dimension H2 reduces the dimension H of rear wheel 5B into recess 210+ the size of the safety clearance C2.
In contrast, the height dimension H1 of the escalator in the related art in which the groove 21 is not formed is equal to the sum of the distance C1 from the top of the frame 4 to the step 5A on the forward side, the height dimension H1 from the top of the step 5A on the forward side to the cross beam 14, the height dimension H2 of the cross beam 14, the safety distance C2 '(═ C2) between the lower portion of the cross beam 14 and the rear wheel 5B of the return-side step 5B, the height dimension H3' (-H3) from the top of the rear wheel 5B of the return-side step 5B to the lower portion of the step 5B, the safety gap C3 '(-C3) between the lower portion of the step 5B and the oil pan 15A, and the height dimension H4' (-H4) of the oil pan 15A and the floor 15, the height dimension H2 being t + C2+ H40The dimension H is increased as compared with the present embodiment0+C2。
As described above, according to the present embodiment, since the height H2 of the intermediate area 4C of the frame 4 can be reduced without designing the structure of the steps (steps 5, 5a, 5B) including the wheels (front wheels a and rear wheels 5B) to a special structure, it is possible to minimize the excavation amount of the stairs, walkways, and the like when the escalators 1 are installed in the stairs, walkways, and the like.
In the above-described embodiment, the cross member 14 is described as an example using an integrally formed sectional material having an L-shaped cross section, but the cross member 14 in the modification shown in fig. 3 may be used to obtain the same effect. In fig. 3, the same portions as those in fig. 1 and 2 are denoted by the same reference numerals, and redundant detailed description is omitted.
That is, in the present modification, the cross member 14 is constituted by a rectangular small-cross-section horizontal member 23 serving as a member for preventing the collapse of the side frames 13, and a rectangular cross-section vertical member 24 serving as a member for supporting the load of the step 5a on the forward side, the passenger, and the like, and the vertical member 24 is integrally connected to the width-direction end of the horizontal member 23 by a known connection method such as welding.
A cutout (recess) 25 is formed in the vertical member 24, and the rear wheel 5B of the return-side step 5B passes through the cutout while securing a safety clearance with respect to the horizontal member 23. By causing the rear wheel 5B of the return-side step 5B to travel in the space formed by the cutout 25, the return-side step 5B can be brought close to the horizontal member 23 as a whole, and as a result, the height of the intermediate region 4C of the frame 4 can be reduced.
In the above-described embodiment, the escalator 1 disposed obliquely has been described as an example, but the present invention can be applied to a special escalator 26 shown in fig. 4. In the application example of fig. 4, the same portions as those in fig. 1 are denoted by the same reference numerals, and redundant detailed description is omitted.
That is, the frame 4 of the escalator 26 is composed of an upper machine room region 4A and a lower machine room region 4B formed at both end portions in the longitudinal direction, an inclined intermediate region 4D in which a forward path and a backward path of the steps 5 are obliquely provided and which is continuous with the upper machine room region 4A, and a horizontal intermediate region 4E formed between the inclined intermediate region 4D and the lower machine room region 4B.
In the escalator 26 thus constructed, the structure of the cross section at the line B-B of the inclined intermediate zone 4D and the cross section at the line C-C of the horizontal intermediate zone 4E is formed as shown in fig. 2 or fig. 3, so that the height dimension of the frame 4 can be reduced.
A second embodiment of the present invention will be described below with reference to fig. 5 and 6. In fig. 1 to 4, as the passenger conveyor, the escalators 1 and 26 disposed in the inclined area are explained, and the second embodiment is explained by taking the electric path 27 disposed in the horizontal area as an example.
The basic structure of the motor tunnel 27 is the same as the escalators 1, 26. The same portions are denoted by the same reference numerals, and detailed description thereof is omitted.
The power flow path 27 is provided side by side on the horizontal sidewalk GL or in a gently inclined area, and the linearly extending frame 4 is composed of a first machine room area 4a and a second machine room area 4b, which are located at both end portions in the longitudinal direction and in which a first machine room 10A and a second machine room 12A are formed, respectively, and an intermediate area 4c formed between the first machine room area 4a and the second machine room area 4 b. Inside the frame 4, the forward-side wheel rail 28A and the return-side wheel rail 28B are supported on the side frames 13 via the cross member 14 and the brackets 20.
On the other hand, a plurality of pedals 29(29a, 29b) are connected to an endless chain 17 provided around the drive sprocket 9 and the driven sprocket 11 driven by the drive device 8. A pair of left and right wheels 30 are pivotally supported at the front and rear in the traveling direction of each pedal 29, and each wheel 30 travels under the guidance of the forward wheel rail 28A and the return wheel rail 28B.
In the power flow path 27 having the above-described configuration, the recessed groove (recessed portion) 31 is formed in the vertical member 14B of the cross member 14 facing the return-side step 29B, and the wheel 30 of the return-side step 29B is caused to travel in the recessed groove 31, whereby the return-side step 29B can be brought closer to the forward-side step 29a, and as a result, the height of the side frame 13, in other words, the height of the intermediate region 4c of the frame 4 can be reduced.
Therefore, as in the first embodiment, since the height of the intermediate region 4C of the frame 4 can be reduced without designing the structure of the step 29 including the wheels 30 to be a special structure, when the electric path 27 is provided in the existing path, the excavation amount of the existing path can be limited to the minimum.
Note that, although the electric path 27 of the second embodiment shown in fig. 5 has been described by way of example as being installed on a horizontal sidewalk GL, it goes without saying that the present invention can also be applied to a case where an electric path is installed on a sidewalk that is gently inclined.
