Description

本発明は、乗客を輸送するエスカレーターや電動道路等の乗客コンベアに係り、特に、踏板の車輪に異常が発生しても安全性を確保することのできる乗客コンベアに関する。 The present invention relates to passenger conveyors such as escalators and electric roads for transporting passengers, and more particularly to passenger conveyors that can ensure safety even if an abnormality occurs in the wheels of a tread.

従来から、踏板の車輪の異常発生時における乗客の安全性を確保することが行われていた。特に、特許文献１には、踏板の車輪の走行を案内する案内レールとは別に支持レールを設け、前後の車輪に異常が発生した場合、それぞれ踏段チェーンの下端，ライザの下端が、上記支持レールの上面によって支えられ、乗降口に設けられた櫛板と踏板との間に隙間が発生するのを防止することが記載されている。 Conventionally, it has been performed to ensure the safety of passengers when an abnormality occurs in the treadle wheels. In particular, in Patent Document 1, a support rail is provided separately from the guide rail for guiding the running of the tread wheel, and when an abnormality occurs in the front and rear wheels, the lower end of the step chain and the lower end of the riser are respectively connected to the support rail. It is described that a gap is prevented from being generated between a comb board and a tread board provided at the entrance and exit.

In order to achieve the above-mentioned object, in the passenger conveyor of the present invention , a step board connected endlessly and circulated, a balustrade opposed to both sides of the direction of movement of the tread board, and a peripheral edge of the balustrade are moved. in a passenger conveyor having a moving handrail, the support shaft fixed to the tread plate, a wheel provided on the support shaft, having a step chain coupled to the support shaft, guiding the wheels provided in the tread plate And a rail having a portion for supporting the tread from below when an abnormality occurs, the rail having a U-shaped cross section perpendicular to the moving direction of the tread, and one end of the wheel It is arranged below the support shaft, the wheel, and the tread plate chain so that the other end is opposed to the bottom of the tread plate .

本発明によれば、踏板の車輪の異常発生時における乗客の安全性を確保することは勿論のこと、踏段チェーンの油漏れを防ぎ、剛性や製作性等を向上させた乗客コンベアを実現できる。 ADVANTAGE OF THE INVENTION According to this invention, the passenger conveyor which prevented the oil leakage of a step chain and improved rigidity, manufacturability, etc. as well as ensuring the safety of the passenger at the time of abnormality of the wheel of a tread is realizable.

以下、本発明の実施例につき、図１〜図４を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.

図１に示す通り、通常、建築物や地盤の床１を掘削して設けた設置用溝２内に設置される電動道路３は、前記設置用溝２内に設置される枠体４と、この枠体４の長手方向両端部に形成された機械室５，６内に軸支された駆動スプロケット７及び従動スプロケット８と、これら駆動スプロケット７と従動スプロケット８間に無端状に巻掛けられた踏板チェーン９と、この踏板チェーン９に無端状に連結されて循環移動する複数の踏板１０と、これら踏板１０の移動方向両側に対向する前記枠体４に立設された欄干１１と、この欄干１１の周縁に案内されて移動する移動手摺１２と、前記機械室５内に設置され前記駆動スプロケット７を駆動する駆動装置１３とを備えている。 As shown in FIG. 1, an electric road 3 that is usually installed in an installation groove 2 provided by excavating a floor 1 of a building or ground includes a frame body 4 installed in the installation groove 2, and The drive sprocket 7 and the driven sprocket 8 that are pivotally supported in the machine chambers 5 and 6 formed at both ends in the longitudinal direction of the frame body 4, and are wound endlessly between the drive sprocket 7 and the driven sprocket 8. A tread plate chain 9, a plurality of tread plates 10 connected endlessly to the tread plate chain 9 and circulated; a balustrade 11 erected on the frame 4 facing both sides of the tread plate 10 in the moving direction; 11 is provided with a moving handrail 12 that moves while being guided by the peripheral edge of 11, and a drive device 13 that is installed in the machine room 5 and drives the drive sprocket 7.

さらに、駆動軸１７と同軸に動力伝達用スプロケット２０が固定されており、この動力伝達用スプロケット２０と前記駆動装置１３の出力スプロケット２１間にチェーン２２を巻掛けて前記駆動軸１７を回転駆動している。 Further, a power transmission sprocket 20 is fixed coaxially with the drive shaft 17, and a chain 22 is wound between the power transmission sprocket 20 and the output sprocket 21 of the drive device 13 to rotationally drive the drive shaft 17. ing.

前記駆動装置１３は、電動機２３と、この電動機２３の回転速度を減速して前記出力スプロケット２１に伝える減速機２４とを備えている。 The driving device 13 includes an electric motor 23 and a speed reducer 24 that reduces the rotational speed of the electric motor 23 and transmits it to the output sprocket 21.

また、前記枠体４の長手方向両端部に位置する機械室５，６の上部には、前記踏板１０の方向転換部を被い、前記床１と面一となる乗降床２５，２６が着脱自在に設置されている。 Moreover, the upper and lower machine chambers 5 and 6 located at both ends in the longitudinal direction of the frame body 4 cover the direction changing portions of the treads 10 and are mounted on and removed from the floors 25 and 26 which are flush with the floor 1. It is installed freely.

前記踏板１０の幅方向両端には、図２に示す通り、支軸２７が固定されており、この支軸２７の先端に車輪本体２８が回転自在に装着され、この車輪本体２８の外周には車輪ゴム２９が設けられている。また、支軸２７には踏板チェーン９が連結されており、踏板
１０を前記駆動スプロケット７と従動スプロケット８との間で循環移動させている。このとき、車輪本体２８は、前記枠体４内に敷設された案内支持レール３０に案内されて回転しながら移動することになるが、案内支持レール３０との接触は、車輪ゴム２９を介して行われる。 As shown in FIG. 2, a support shaft 27 is fixed to both ends of the tread plate 10 in the width direction, and a wheel body 28 is rotatably attached to the tip of the support shaft 27. Wheel rubber 29 is provided. Further, a tread plate chain 9 is connected to the support shaft 27, and the tread plate 10 is circulated and moved between the drive sprocket 7 and the driven sprocket 8. At this time, the wheel body 28 moves while being guided and rotated by the guide support rail 30 laid in the frame 4, but the contact with the guide support rail 30 is made via the wheel rubber 29. Done.

案内支持レール３０は、踏板１０の移動方向と垂直な断面が一部品でＵ字状となるように形成されている。ここで、Ｕ字状とは、左右の鉛直部と底部とが直角となっているもの、左右の鉛直部の高さが異なっているものも含まれる。そして、Ｕ字状の案内支持レール３０の鉛直部３０Ａ（高さの低い方）側が電動道路の幅方向内側になるように設置し、鉛直部Ｂ（高さの高い方）側が電動道路の幅方向外側になるように設置する。また、案内支持レール３０は、鉛直部３０Ｂ側の底部で、車輪本体２８の外周の車輪ゴム２９を受ける一方、鉛直部３０Ａの上端を踏板１０の底部に対向させる。 The guide support rail 30 is formed so that a cross section perpendicular to the moving direction of the tread plate 10 is a U-shape with one component. Here, the U-shape includes those in which the left and right vertical portions and the bottom are at right angles, and those in which the heights of the left and right vertical portions are different. Then, the U-shaped guide support rail 30 is installed so that the vertical portion 30A (lower height) side is on the inner side in the width direction of the electric road, and the vertical portion B (higher height) side is the width of the electric road. Install so that it is on the outside in the direction. The guide support rail 30 receives the wheel rubber 29 on the outer periphery of the wheel main body 28 at the bottom on the vertical portion 30B side, and makes the upper end of the vertical portion 30A face the bottom of the tread board 10.

つまり、踏板１０の両端に設けられた車輪を案内する部分と、車輪の異常発生時例えば車輪ゴム２９が離脱したときなどに踏板１０を下方から支持する部分とは、一体的に形成されている。このように、車輪の異常発生時における踏板支持機能を兼ね備えた案内支持レール３０が、一体的にＵ字状に形成されているので、すなわち、別個の構成物を複数組み合わせて形成されていないので、部品製作性，組立性，剛性，コストがいずれも向上する。 That is, a portion for guiding the wheels provided at both ends of the tread plate 10 and a portion for supporting the tread plate 10 from below when the wheel abnormality occurs, for example, when the wheel rubber 29 is detached, are integrally formed. . As described above, the guide support rail 30 having the function of supporting the tread at the time of occurrence of the wheel abnormality is integrally formed in a U-shape, that is, it is not formed by combining a plurality of separate components. , Parts manufacturability, assembly, rigidity, and cost are all improved.

また、通常時、案内支持レール３０の鉛直部３０Ａの上面は、踏板１０の下方にギャップＧを保たれており、乗降口付近では、踏板１０が図３の実線の位置にある。仮に、踏板１０を下方から支持する部分がない場合、車輪ゴム２９が離脱すると、踏板１０が図３の点線の位置に落ち込むので、踏板１０と櫛歯３１あるいは櫛板３２との間に隙間が生じ、乗客の足等が挟まれてしまう可能性がある。つまり、本実施例のように案内支持レール
３０を構成することで、車輪の異常発生時にも乗客の安全性を確保することができる。 Further, at the normal time, the upper surface of the vertical portion 30A of the guide support rail 30 is maintained with a gap G below the tread board 10, and the tread board 10 is in the position of the solid line in FIG. If there is no portion that supports the tread plate 10 from below, the tread plate 10 falls to the position of the dotted line in FIG. 3 when the wheel rubber 29 is detached, so that there is a gap between the tread plate 10 and the comb teeth 31 or the comb plate 32. This may cause a passenger's foot to be caught. That is, by configuring the guide support rail 30 as in the present embodiment, it is possible to ensure passenger safety even when an abnormality occurs in the wheels.

更に、図４に示す通り、この案内支持レール３０の鉛直部３０Ａの上面は、踏板チェーン９の連結や車輪の取付等の作業を行う際に、重い踏板１０を枠体４内に仮置きするのにも利用できるので、作業性が向上する。 Further, as shown in FIG. 4, the upper surface of the vertical portion 30 </ b> A of the guide support rail 30 temporarily places the heavy tread 10 in the frame body 4 when performing operations such as connecting the tread chain 9 and attaching wheels. Therefore, workability is improved.

また、断面がＵ字状の案内支持レール３０を一体的に形成しているので、踏板チェーン９の油が垂れても、Ｕ字状の案内支持レール内に溜めることができ、油が漏れる恐れがなくなる。 Further, since the guide support rail 30 having a U-shaped cross section is integrally formed, even if oil in the tread plate chain 9 drips, it can be stored in the U-shaped guide support rail, and oil may leak. Disappears.

尚、案内支持レール３０の長手方向（踏板１０の移動方向）については、Ｕ字状の案内支持レール３０を複数継ぎあわせて、一方の乗降床２５から他方の乗降床２６までの長さを確保している。つまり、乗降口付近も中間部付近も、案内支持レール３０の断面がＵ字状となっている。また、隣接する案内支持レール３０の継ぎあわせ部分については、下方から被覆部材３３で覆って隙間をなくし、油等が漏れないようにする。 As for the longitudinal direction of the guide support rail 30 (the moving direction of the tread plate 10), a plurality of U-shaped guide support rails 30 are joined together to ensure the length from one boarding / exiting floor 25 to the other boarding / exiting floor 26. is doing. That is, the cross section of the guide support rail 30 is U-shaped near both the entrance and exit and the middle portion. In addition, the joint portions of the adjacent guide support rails 30 are covered with the covering member 33 from below to eliminate a gap so that oil or the like does not leak.
