Description

本発明は、支持部に制動部と綱車を備えた薄型巻上機を、昇降路と乗かご間に配置したエレベーター装置に関するものである。   The present invention relates to an elevator apparatus in which a thin hoisting machine having a braking part and a sheave on a support part is arranged between a hoistway and a car.

昇降路内に設置するエレベーター用巻上機は、ブレーキの制動面（ブレーキドラムやブレーキディスク）を主索の油、モータ軸受けのグリス、レール油から保護する必要がある。そのため、昇降路頂部設置やピット設置の胴長巻上機の場合は、綱車とブレーキ制動面はモータの軸方向のそれぞれ端部に配置されており、ロープ油の影響を受けない構造としている。また、昇降路中間部に乗りかごと昇降路壁の間に設置の薄型巻上機の場合においても、綱車と制動面を隔てる構造とし、主索の油付着を防止している（例えば、特許文献１参照）。   An elevator hoist installed in a hoistway needs to protect the braking surface (brake drum and brake disc) of a brake from oil of main rope, grease of motor bearings, and rail oil. Therefore, in the case of a hoisting hoist with a hoistway top installation or a pit installation, the sheave and the brake braking surface are arranged at the ends of the motor in the axial direction so that they are not affected by the rope oil. . Also, in the case of a thin hoist installed between the car and the hoistway wall in the middle part of the hoistway, the sheave and the braking surface are separated from each other to prevent the main rope from adhering to oil (for example, Patent Document 1).

特許第４１９１３３３号公報Japanese Patent No. 4191333

前述した従来の構造、特に、昇降路中間部に乗りかごと昇降路壁の間に設置の薄型巻上機を設けたものにおいては、綱車と制動面を隔てる構造となっているため、定期点検時に綱車と制動面の両方を確認することとなるが、どちらか一方が確認し難い構造となっている。   In the conventional structure described above, in particular, a thin hoist installed between the car and the hoistway wall at the middle part of the hoistway has a structure that separates the sheave from the braking surface. Both the sheave and the braking surface will be confirmed at the time of inspection, but either one is difficult to confirm.

本発明は、前述した従来技術における実状からなされたもので、その目的は、定期点検時に綱車と制動面の両方を確認しやすくすると共に、綱車から飛散する主索の油から制動面を防ぐことのできるエレベーター装置を提供することにある。   The present invention has been made from the actual state of the prior art described above. The purpose of the present invention is to make it easy to check both the sheave and the braking surface during periodic inspections, and to remove the braking surface from the oil of the main rope scattered from the sheave. It is in providing the elevator apparatus which can prevent.

前記目的を達成するために、本発明では、支持部に制動部と綱車を備えた薄型巻上機を、昇降路と乗かご間に配置し、この乗かごを、前記綱車に巻き掛けられた主索を介して駆動するようにしたエレベーター装置において、前記支持部を昇降路壁側に、綱車を乗りかご側に配置し、これら綱車と支持部間に前記制動部を設け、かつ、この制動部の前記綱車側側面に、前記主索の油が綱車から飛散して前記制動部側面に付着し遠心力によって上部へと移動するのを阻止する溝を備えると共に、この溝に、吸油材を埋め込んだことを特徴とする。 In order to achieve the above object, in the present invention, a thin hoisting machine having a braking part and a sheave on a support part is disposed between a hoistway and a car, and the car is wound around the sheave. In the elevator apparatus that is driven via the main rope, the support portion is disposed on the hoistway wall side, the sheave is disposed on the car side, and the braking portion is provided between the sheave and the support portion, and Rutotomoni provided with a groove to prevent this the sheaves side surface of the brake unit, the oil of the main ropes is moved to the upper by centrifugal force attached to the brake side scattered from sheave, An oil absorbing material is embedded in the groove .

このように構成することにより、定期点検時、制動部と綱車を同一目線で確認でき保守作業を容易なものとすることができると共に綱車からの油飛散に伴う制動面への油付着を防止できる。また、簡単な構成で油飛散に伴う制動面への油付着を防止できる。また、この構成により、より効果的に油飛散に伴う制動面への油付着を防止できる。 By configuring in this way, at the time of periodic inspection, it is possible to confirm the braking unit and the sheave from the same line of view, and to make maintenance work easy, and at the same time, the oil adheres to the braking surface due to oil scattering from the sheave. It can be prevented. Moreover, oil adhesion to the braking surface accompanying oil scattering can be prevented with a simple configuration. In addition, this configuration can more effectively prevent oil from adhering to the braking surface due to oil scattering.

更に、本発明では、前記制動部側面の溝を、上下に複数設けたことを特徴とする。 Furthermore, the present invention is characterized in that a plurality of grooves on the side surface of the braking portion are provided in the vertical direction.

この構成により、より効果的に油飛散に伴う制動面への油付着を防止できる。 With this configuration, Ru prevents good Ri effectively adhered oil to the braking surface caused by oil splashing.

本発明によれば、定期点検時、制動部と綱車を同一目線で確認でき保守作業を容易なものとすることができると共に綱車からの油飛散に伴う制動面への油付着を防止できる。   According to the present invention, at the time of periodic inspection, the braking unit and the sheave can be confirmed from the same line of view, and maintenance work can be facilitated, and oil adhesion to the braking surface due to oil splashing from the sheave can be prevented. .

以下、本発明に係るエレベーター装置の実施形態について、詳細に説明する。   Hereinafter, embodiments of an elevator apparatus according to the present invention will be described in detail.

図に示すように、１は昇降路で、この昇降路1内に乗かご３が設けられ、この乗かご3と昇降路壁2との間に、巻上機４が設置されている。この巻上機４は、綱車５と制動部６と支持部７で構成されており、図1に示すように乗かご３側から昇降路壁2に向かって、綱車５、制動部６、支持部７となっており、制動部６及び綱車７が乗りかご側にあることから、定期点検時の目視確認が容易となっている。８は乗かご３用のガイドレール、９はカウンターウエート、１０はこのカウンターウエート９用のガイドレールである。前記乗かご３とカウンターウエート９は主索１１によって連結されており、この主索１１が綱車５に巻き掛けられ、この綱車５によって主索１１が駆動され、前記乗かご３とカウンターウエート９とを昇降するようになっている。   As shown in the figure, reference numeral 1 denotes a hoistway, and a car 3 is provided in the hoistway 1, and a hoisting machine 4 is installed between the car 3 and the hoistway wall 2. The hoisting machine 4 is composed of a sheave 5, a braking part 6 and a support part 7, and as shown in FIG. 1, the sheave 5 and the braking part 6 are directed from the car 3 side toward the hoistway wall 2. Since the brake unit 6 and the sheave 7 are on the car side, the visual check at the regular inspection is easy. 8 is a guide rail for the car 3, 9 is a counterweight, and 10 is a guide rail for the counterweight 9. The car 3 and the counterweight 9 are connected by a main rope 11, and the main rope 11 is wound around a sheave 5, and the main rope 11 is driven by the sheave 5, and the car 3 and the counterweight are driven. 9 is moved up and down.

次に、油付着の状況について説明する。前記主索1１には、通常、グリースが塗布されている。このため、主索１１の接する綱車５には油が付着する。この綱車５に付着した油は矢印１２に示すように飛散して制動部６の側面６ａに油１３として付着し、この付着した油１３は遠心力により制動部６の制動面６ｂへ移動する。この制動面６ｂへ移動した油１３が制動面６ｂに付着すると制動機能が低下し大きな問題を生じる可能性がある。このため、油１３が制動面６ｂに移動するのを阻止する必要がある。この油１３の移動を阻止する手段として本発明では、制動部６の側面６ａに溝１４を設けたものである。このように構成することにより、側面６ａに付着して移動してきた油１３を矢印１５の方向へ飛ばすことが可能となる。これにより制動面６ｂへの付着を保護することができ、ブレーキの制動力を確保することが可能となる。   Next, the situation of oil adhesion will be described. The main rope 11 is usually coated with grease. For this reason, oil adheres to the sheave 5 with which the main rope 11 contacts. The oil adhering to the sheave 5 scatters as shown by an arrow 12 and adheres to the side surface 6a of the braking unit 6 as oil 13, and the adhering oil 13 moves to the braking surface 6b of the braking unit 6 by centrifugal force. . If the oil 13 that has moved to the braking surface 6b adheres to the braking surface 6b, the braking function may be reduced, causing a serious problem. For this reason, it is necessary to prevent the oil 13 from moving to the braking surface 6b. In the present invention, a groove 14 is provided on the side surface 6 a of the braking portion 6 as means for preventing the movement of the oil 13. With this configuration, it is possible to fly the oil 13 that has adhered to the side surface 6 a and moved in the direction of the arrow 15. As a result, adhesion to the braking surface 6b can be protected, and the braking force of the brake can be secured.

図５に示すように、制動部６の側面６ａに溝１４内に吸油材１６を埋め込むなら、油１３付着時に油を吸い取ることができより効果的に阻止することができる。   As shown in FIG. 5, if the oil absorbing material 16 is embedded in the groove 14 on the side surface 6 a of the braking portion 6, the oil can be sucked when the oil 13 adheres and can be more effectively prevented.

図６に示すように、制動部６の側面６ａに複数本の溝１４Ａ−１４Ｃを設けるなら、油１３を確実に矢印１５の方向に飛ばすことが可能となり、油１３の移動をより効果的に阻止することができる。   As shown in FIG. 6, if a plurality of grooves 14 </ b> A- 14 </ b> C are provided on the side surface 6 a of the braking portion 6, the oil 13 can be reliably blown in the direction of the arrow 15, and the movement of the oil 13 is more effectively performed. Can be blocked.
