The prior art disclosed in Patent Document 1 includes an oil drain plate, that is, an oil drain plate, having an end portion disposed outside the horizontal projection surface of the tread plate. The oil drain plate extends along the longitudinal direction of the driven wheel tread rail, and is attached to the driven wheel tread rail in a suspended state by a mounting bracket and a leaf spring. This prior art prevents the oil flowing down on the follower wheel tread rail from being swept away from the horizontal projection surface of the tread from the aforementioned end of the oil drain plate, thereby preventing the tread from being contaminated by the lubricating oil flowing down. is there.
前述した従来技術にあっては、踏板に滴下する潤滑油の取りこぼしを避けるためには、従転輪踏板レールの全長に対応する取り付けが必要となる。このために排油板の取り付け作業が大掛かりで煩雑になり、取り付け作業工数が増加し、これに伴って取り付け費用が高くなってしまう。 In the above-described prior art, in order to avoid spilling of the lubricating oil dripping onto the tread, it is necessary to attach the entire length of the driven wheel tread rail. For this reason, the installation work of the oil drain plate becomes large and complicated, and the number of installation work steps increases, and the installation cost increases accordingly.

このように構成した本実施形態は、踏板チェーン２に供給された潤滑油１３のうちの余剰の潤滑油１３は、往き側案内レール５のレール部材５ａの継ぎ目、すなわち隙間部から浸入してレール部材５の下面５ａ１に流れ込む。この下面５ａ１を流れる潤滑油１３は、下面５ａ１に取り付けられた第２油切板１２の例えば取り付け板部１２ａから垂直に配置された垂下板部１２ｂに導かれ、この垂下板部１２ｂの前述したテーパ縁部を伝わって最下位置であるこのテーパ縁部の下端部から、踏板１の水平投影面の外において流下する。 In this embodiment configured as described above, surplus lubricating oil 13 of the lubricating oil 13 supplied to the tread chain 2 enters the joint of the rail member 5a of the forward guide rail 5, that is, the gap portion and enters the rail. It flows into the lower surface 5a1 of the member 5. The lubricating oil 13 flowing through the lower surface 5a1 is guided to, for example, the hanging plate portion 12b disposed vertically from the mounting plate portion 12a of the second oil cutting plate 12 attached to the lower surface 5a1, and the above-mentioned of the hanging plate portion 12b is described above. It flows down outside the horizontal projection surface of the tread 1 from the lower end of this tapered edge, which is the lowest position, along the tapered edge.
また、踏板チェーン２の潤滑油１３のうちの第２油切板１２によって除去された潤滑油１３の残りは、第１帰り側案内レール６のレール部材６ａの継ぎ目、すなわち図４に示す隙間部９から浸入してレール部材６ａの下面６ａ１に流れ込む。この下面６ａ１を流れる潤滑油１３は、下面６ａ１に取り付けられた第１油切板１１の例えば取り付け板部１１ａから垂直に配置された垂下板部１１ｂに導かれ、この垂下板部１１ｂの図５の（ａ）図に示すテーパ縁部１１ｂ１を伝わって最下位置であるこのテーパ縁部１１ｂ１の下端部１１ｂ２から、踏板１の水平投影面の外において流下する。 Further, the remainder of the lubricating oil 13 removed by the second oil cutting plate 12 of the lubricating oil 13 of the tread plate chain 2 is the joint of the rail member 6a of the first return side guide rail 6, that is, the gap portion shown in FIG. 9 enters and flows into the lower surface 6a1 of the rail member 6a. The lubricating oil 13 flowing through the lower surface 6a1 is guided to, for example, the hanging plate portion 11b of the first oil cutting plate 11 attached to the lower surface 6a1 from the mounting plate portion 11a, and the dripping plate portion 11b is shown in FIG. It flows down from the lower end part 11b2 of this taper edge part 11b1 which is the lowest position through the taper edge part 11b1 shown in FIG.
前述のようにして第２油切板１２及び第１油切板１１から流下した余剰の潤滑油１３は、当該エスカレータの踏板１の下方部に配置された図示しない油溜めに収容される。このように本実施形態は、踏板チェーン２の潤滑油１３のうちの余剰の潤滑油１３を、第１油切板１１及び第２油切板１２を介して流下させることにより、踏板１上に滴下することなく油溜めに収容することができる。これにより潤滑油１３による踏板１の汚損を防止することができる。 Excess lubricating oil 13 flowing down from the second oil cutting plate 12 and the first oil cutting plate 11 as described above is accommodated in an oil sump (not shown) disposed below the tread plate 1 of the escalator. As described above, in the present embodiment, surplus lubricating oil 13 of the lubricating oil 13 of the tread chain 2 is caused to flow down through the first oil cutting plate 11 and the second oil cutting plate 12 and thereby onto the tread plate 1. It can be accommodated in an oil sump without dripping. Thereby, the tread 1 can be prevented from being soiled by the lubricating oil 13.
本実施形態に係る踏板汚損防止装置、及び踏板汚損防止装置に用いられる油切板によれば、第１油切板１１が、第１帰り側案内レール６を形成するレール部材６ａの下面６ａ１に当接し、この下面６ａ１に取り付けられる取り付け板部１１ａと、この取り付け板部１１ａから垂下する垂下板部１１ｂとを有し、取り付け板部１１ａの長さ寸法を、第１帰り側案内レール６を形成する複数のレール部材６ａのうちの１本のレール部材６ａの長さ寸法よりも短く設定したことから、例えば取り付け板部１１ａの長さ寸法を、取り付け板部１１ａの幅寸法以下に設定したことから、第１油切板１１を小さな形状とすることができ、第１油切板１１の取り付け作業が簡単になる。これにより本実施形態は、取り付け作業工数を少なくすることができ、取り付け費用を安く抑えることができる。 According to the treadle pollution prevention device and the oil drainage plate used in the treadle pollution prevention device according to the present embodiment, the first oil drainage plate 11 is placed on the lower surface 6a1 of the rail member 6a that forms the first return side guide rail 6. There is a mounting plate portion 11a that abuts and is attached to the lower surface 6a1, and a hanging plate portion 11b that hangs down from the mounting plate portion 11a. The length dimension of the mounting plate portion 11a is determined by the first return side guide rail 6. Since the length dimension of one rail member 6a among the plurality of rail members 6a to be formed is set to be shorter, for example, the length dimension of the attachment plate portion 11a is set to be equal to or less than the width dimension of the attachment plate portion 11a. Therefore, the first oil cutting plate 11 can be made into a small shape, and the mounting operation of the first oil cutting plate 11 is simplified. Thereby, this embodiment can reduce an installation operation man-hour and can hold down installation cost cheaply.
さらに図４に示したように、第１油切板１１は、レール部材６ａの下面６ａ１に流れ込む潤滑油１３の流入源である隙間部９の下方に部分的に設けるだけで、潤滑油１３を踏板１の下方部に配置された図示しない油溜めに効果的に導くことができるため、レール部材６ａ全体に設ける必要が無くなり、第１油切板１１全体の重量を軽くでき、それに応じてその取り付け費用を安く抑えることができる。 Further, as shown in FIG. 4, the first oil cutting plate 11 is provided with the lubricating oil 13 only by being partially provided below the gap 9 which is an inflow source of the lubricating oil 13 flowing into the lower surface 6a1 of the rail member 6a. Since it can be effectively guided to the oil sump (not shown) disposed in the lower part of the tread board 1, it is not necessary to provide the rail member 6a as a whole, and the weight of the first oil cutting plate 11 can be reduced, and accordingly Installation costs can be reduced.
また本実施形態に係る踏板汚損防止装置、及び踏板汚損防止装置に用いられる油切板は、第１油切板１１の重量を軽くすることができるので、第１帰り側案内レール６の歪みの発生を抑えることができる。これにより本実施形態は、第１油切板１１を取り付けた後にもエスカレータの良好な乗り心地の確保と、エスカレータの安定した運行を実現させることができる。さらに本実施形態は、第１帰り側案内レール６の歪みの発生が抑えられるので、第１油切板１１の踏板１への接触に伴う落下の虞はなく、これによっても当該エスカレータを安定して運行させることができる。 Moreover, since the oil cutting board used for the tread board pollution prevention apparatus and the tread board pollution prevention apparatus according to the present embodiment can reduce the weight of the first oil cutting board 11, the distortion of the first return side guide rail 6 can be reduced. Occurrence can be suppressed. Thereby, after attaching the 1st oil cut board 11, this embodiment can ensure the favorable riding comfort of an escalator, and can implement | achieve the stable operation | movement of an escalator. Furthermore, in this embodiment, since the occurrence of distortion of the first return side guide rail 6 is suppressed, there is no possibility of dropping due to the contact of the first oil cut plate 11 with the tread plate 1, and this also stabilizes the escalator. Can be operated.
また、本実施形態に係る踏板汚損防止装置は、前述した第１油切板１１と類似の形状の第２油切板１２を備えたことから、前述した第１油切板１１におけるのと同様の作用効果を、第２油切板１２によっても得ることができる。すなわち、第２油切板１２の取り付け板部１２ａの長さ寸法を、往き側案内レール５を形成する複数のレール部材５ａのうちの１本のレール部材５ａの長さ寸法よりも短く設定したことから、例えば取り付け板部１２ａの長さ寸法を幅寸法以下に設定したことから、第２油切板１２を小さな形状とすることができ、第２油切板１２の取り付け作業が簡単になる。 Moreover, since the tread board fouling prevention apparatus according to the present embodiment includes the second oil cut plate 12 having a shape similar to the first oil cut plate 11 described above, the same as that in the first oil cut plate 11 described above. The effect of the above can also be obtained by the second oil cut plate 12. That is, the length dimension of the mounting plate portion 12a of the second oil cut plate 12 is set to be shorter than the length dimension of one rail member 5a among the plurality of rail members 5a forming the forward guide rail 5. Therefore, for example, since the length dimension of the mounting plate portion 12a is set to be equal to or less than the width dimension, the second oil cutting plate 12 can be made into a small shape, and the mounting operation of the second oil cutting plate 12 is simplified. .
また、第２油切板１２の重量を軽くすることができるので、往き側案内レール５の歪みの発生も抑えることができる。これにより、第２油切板１２を取り付けた後にもエスカレータの良好な乗り心地の確保と、エスカレータの安定した運転を実現させることができる。 Moreover, since the weight of the 2nd oil cutting board 12 can be made light, generation | occurrence | production of the distortion of the going-out side guide rail 5 can also be suppressed. Thereby, even after attaching the 2nd oil cutting board 12, ensuring of the favorable riding comfort of an escalator and the stable driving | operation of an escalator are realizable.
また、本実施形態に係る踏板汚損防止装置は、第１油切板１１と第２油切板１２とを設け、第２油切板１２で除去された潤滑油１３の残りの潤滑油１３を第１油切板１１で除去することから、潤滑油１３の除去機能に優れ、第１油切板１１で除去する潤滑油１３の量を少なくすることができ、第１帰り側案内レール６によって案内される踏板１への潤滑油１３の滴下を確実に防止することができる。 Further, the treadle fouling prevention apparatus according to the present embodiment includes the first oil cutting plate 11 and the second oil cutting plate 12, and the remaining lubricating oil 13 of the lubricating oil 13 removed by the second oil cutting plate 12 is provided. Since it removes with the 1st oil cutting board 11, it is excellent in the removal function of the lubricating oil 13, the quantity of the lubricating oil 13 removed with the 1st oil cutting board 11 can be decreased, and by the 1st return side guide rail 6, It is possible to reliably prevent the lubricating oil 13 from dropping on the guided tread 1.
なお、前述した実施形態に係る踏板汚損防止装置は、第１油切板１１の取り付け板部１１ａを第１帰り側案内レール６を形成するレール部材６ａの下面６ａ１に接着手段によって取り付け、第２油切板１２の取り付け板部１２ａを往き側案内レール５を形成するレール部材５ａの下面５ａ１に接着手段によって取り付けてあるが、接着手段によらずに溶接によって、第１油切板１１の取り付け板部１１ａをレール部材６ａの下面６ａ１に取り付けてもよく、また、第２油切板１２の取り付け板部１２ａをレール部材５ａの下面５ａ１に取り付けるようにしてもよい。 In the tread board fouling prevention device according to the above-described embodiment, the attachment plate portion 11a of the first oil drain plate 11 is attached to the lower surface 6a1 of the rail member 6a forming the first return side guide rail 6 by an adhesive means. The mounting plate portion 12a of the oil cutting plate 12 is attached to the lower surface 5a1 of the rail member 5a forming the forward guide rail 5 by an adhesive means, but the first oil cutting plate 11 is attached by welding without using the adhesive means. The plate portion 11a may be attached to the lower surface 6a1 of the rail member 6a, and the attachment plate portion 12a of the second oil cut plate 12 may be attached to the lower surface 5a1 of the rail member 5a.
また、前述した実施形態に係る踏板汚損防止装置、及び踏板汚損防止装置に用いられる油切板は、第１油切板１１及び第２油切板１２を金属板によって形成してあるが、これらの第１油切板１１及び第２油切板１２を合成樹脂によって形成してもよい。 Moreover, although the oil-cut board used for the tread board pollution prevention apparatus which concerns on embodiment mentioned above, and the tread board pollution prevention apparatus has formed the 1st oil-cut board 11 and the 2nd oil-cut board 12 with the metal plate, these The first oil cut plate 11 and the second oil cut plate 12 may be made of synthetic resin.
また、前述した実施形態に係る踏板汚損防止装置は、第１油切板１１と第２油切板１２とを備えているが、第１油切板１１のみを備えた構成にしてもよい。このように構成したものでは、前述した実施形態に比べて第１帰り側案内レール６に流れ込む潤滑油１３の量が多くなる傾向があるが、このような場合でも、第１油切板１１を介して第１帰り側案内レール６を形成するレール部材６ａの下面６ａ１に流れ込んだ潤滑油１３を踏板１の外部に流下させて、踏板１を潤滑油１３で汚損しないように保つことが可能となる。 Moreover, although the tread board fouling prevention device according to the above-described embodiment includes the first oil cut plate 11 and the second oil cut plate 12, a configuration including only the first oil cut plate 11 may be employed. In such a configuration, the amount of the lubricating oil 13 flowing into the first return side guide rail 6 tends to be larger than in the above-described embodiment, but even in such a case, the first oil cutting plate 11 is disposed. The lubricating oil 13 that has flowed into the lower surface 6a1 of the rail member 6a that forms the first return guide rail 6 can be caused to flow down to the outside of the tread board 1 so that the tread board 1 can be kept from being contaminated with the lubricating oil 13.
