The winch (4) comprises a braked body (8), a brake device (9) and a motor frame (10), wherein a brake component (11) is pressed on the peripheral part (8a) of the braked body (8) through the brake device (9) so as to execute brake; a bearing component (17) with reacting force consists of the motor frame (10) so that the bearing component (17) with reacting force bears the friction force caused by the rotated braked body (8) when the brake component (11) presses the braked body (8).

Description

本発明は巻上機及びそれを用いたエレベーター装置に関する。   The present invention relates to a hoisting machine and an elevator apparatus using the same.

巻上機のブレーキとして、巻上機の回転に同期して回転する円筒状の被制動体外周部に制動部材を押圧して制動する方式のブレーキ装置が知られている。この種のブレーキ装置は被制動体に制動部材を押し付けることによって、被制動体の回転を停止するように作用させ、巻上機に制動をかけるものである（例えば特許文献１参照）。   As a brake for a hoisting machine, a brake device of a type in which a brake member is pressed against a cylindrical braked body outer periphery that rotates in synchronization with the hoisting machine to perform braking is known. This type of brake device acts to stop the rotation of the braked body by pressing a braking member against the braked body, thereby braking the hoist (see, for example, Patent Document 1).

被制動体に押し付けられる制動部材には、制動時に被制動体に押し付けられる力に加え、被制動体が回転しているため、その回転方向に向かって共に回転しようとする摩擦力が発生する。この摩擦力は非常に大きな力であるが、被制動体の回転を停止させるためにはこの摩擦力に抗しながら、制動体を被制動体に押し付け続けなければならず、通常はブレーキ本体でこの摩擦力を負担するだけの強度を備えるように構成されている。   In addition to the force pressed against the braked body during braking, the braking member pressed against the braked body generates a frictional force that tries to rotate together in the direction of rotation because the braked body rotates. This frictional force is very large, but in order to stop the rotation of the braked body, it is necessary to keep pressing the braking body against the braked body against this frictional force. It is configured to have a strength sufficient to bear this frictional force.

このような大きな摩擦力を負担するため、ブレーキ装置本体に制動部材の被制動体回転方向への移動を抑制するガイド部を取付けたブレーキ装置なども提案されている（例えば特許文献２参照）。   In order to bear such a large frictional force, there has also been proposed a brake device or the like in which a guide portion that suppresses movement of the braking member in the rotation direction of the braked body is attached to the brake device body (see, for example, Patent Document 2).

特開昭５９−１４４８３５号公報JP 59-144835 A 特開２００６−１６１９２０号公報JP 2006-161920 A

しかし、上記従来技術では被制動体回転方向の摩擦力に耐え得る強度をブレーキ装置自身で確保しているため、ブレーキ本体が大型化し、それらが取り付けられた巻上機自体も大型化させてしまい、巻上機全体の小型化が困難となるという問題があった。   However, in the above prior art, the brake device itself secures the strength that can withstand the frictional force in the rotating direction of the braked body, so that the brake body is enlarged and the hoisting machine to which the brake is attached is also enlarged. There has been a problem that it is difficult to reduce the size of the entire hoisting machine.

また、このような巻上機を昇降路内に設置しようとすると、昇降路内で余分なスペースが必要とされ、効率的なレイアウトひいては省スペース化が難しくなるという問題もあった。   Further, when such a hoisting machine is installed in the hoistway, there is a problem that an extra space is required in the hoistway, and it is difficult to save space efficiently.

また、特許文献２の技術では、点検や交換が必要とされるブレーキシューがガイド部内に位置しているため、制動部材の点検及び交換時に、設置部分からブレーキ本体ごと取り外したり、場合によってはブレーキ本体を分解したりしなければならず、メンテナンス性の向上を図る必要があった。   Further, in the technique of Patent Document 2, since the brake shoe that needs to be inspected and replaced is located in the guide portion, when the brake member is inspected and replaced, the brake body can be removed from the installation portion or in some cases The main body had to be disassembled, and maintenance was required to be improved.

本発明は、小型化に対応することができ、メンテナンス性に優れた巻上機を提供することを目的とする。   An object of this invention is to provide the winding machine which can respond to size reduction and was excellent in maintainability.

また本発明は、効率的なレイアウトひいては省スペース化が可能なエレベーター装置を提供することを目的とする。   It is another object of the present invention to provide an elevator apparatus capable of efficient layout and space saving.

以下、本発明の一実施の形態を例に挙げて、本発明を説明する。   Hereinafter, the present invention will be described by taking an embodiment of the present invention as an example.

図１は本発明の巻上機が適用されたエレベーター装置の全体構成を示す斜視図である。
同図において、エレベーター装置３０は、昇降路２２内を昇降する乗りかご１及び釣合いおもり２、乗りかご１及び釣合いおもり２を吊持するロープである主索３、主索３が駆動シーブ５に巻き掛けられた巻上機４を備えている。そして乗りかご１及び釣合いおもり２は駆動シーブ５に巻き掛けられた主索３が巻上機４によって駆動されることで昇降路内を昇降する。 FIG. 1 is a perspective view showing the overall configuration of an elevator apparatus to which the hoisting machine of the present invention is applied.
In the figure, an elevator apparatus 30 includes a main rope 3 and a main rope 3, which are ropes for suspending a passenger car 1 and a counterweight 2 that move up and down in a hoistway 22, and a passenger car 1 and a counterweight 2. A winding machine 4 is provided. The car 1 and the counterweight 2 are moved up and down in the hoistway when the main rope 3 wound around the drive sheave 5 is driven by the hoisting machine 4.

図２は本発明の巻上機が適用されたエレベーター装置の鉛直方向上方から見た昇降路断面の配置図である。巻上機４は昇降路２２内の一壁面に沿って平行に設置する薄型タイプとなっていて、昇降路２２の内部に配置されている。巻上機４は、主索３が巻き掛けられた駆動シーブ５、駆動シーブ５を回転させるモータ６を内蔵し、駆動シーブ５の回転を制動する制動手段７を有している。なお薄型タイプの巻上機とは、その幅に対して厚さ方向の大きさのほうが小さなタイプの巻上機を言うものとする。   FIG. 2 is a layout diagram of a hoistway cross section as viewed from above in the vertical direction of an elevator apparatus to which the hoisting machine of the present invention is applied. The hoisting machine 4 is a thin type installed in parallel along one wall surface in the hoistway 22, and is disposed inside the hoistway 22. The hoisting machine 4 includes a driving sheave 5 around which the main rope 3 is wound, a motor 6 that rotates the driving sheave 5, and a braking means 7 that brakes the rotation of the driving sheave 5. The thin type hoisting machine means a hoisting machine of a type whose size in the thickness direction is smaller than its width.

図３は本発明の一実施例を示すエレベーター用巻上機の正面図である。制動手段７は、駆動シーブ５の回転軸とその回転軸を同じくするモータ６と一体に回転される被制動体８と、被制動体８の回転を制動するブレーキ装置９を有している。本実施形態では被制動体８として直径に対して厚さのほうが小さな円筒状のブレーキドラムが用いられている。また、ブレーキ装置９は被制動体８の外周円周面に対向して上下に一対備えられており、モーターフレーム１０に取り付けられている。モーターフレーム１０はモータの回転子の周囲に設けられ、モータの強度を補強する役割も果たしている。   FIG. 3 is a front view of an elevator hoist according to an embodiment of the present invention. The braking means 7 has a braked body 8 that is rotated integrally with a rotation shaft of the drive sheave 5 and a motor 6 that has the same rotation axis, and a brake device 9 that brakes the rotation of the braked body 8. In the present embodiment, a cylindrical brake drum having a smaller thickness than the diameter is used as the brake target 8. A pair of brake devices 9 are provided on the upper and lower sides of the brake device 9 so as to face the outer circumferential surface of the braked body 8, and are attached to the motor frame 10. The motor frame 10 is provided around the rotor of the motor and plays a role of reinforcing the strength of the motor.

図４は本発明の一実施例を示す巻上機ブレーキ部分の正面要部拡大図である。ブレーキ装置９は、ロッド１２と、可動鉄心１３と、制動部材１１と、ブレーキばね１４と、電磁マグネット１５から構成されている。電磁マグネット１５は、ブレーキコイル（電磁コイル）１６を有している。   FIG. 4 is an enlarged view of the main part of the front part of the hoisting machine brake portion showing an embodiment of the present invention. The brake device 9 includes a rod 12, a movable iron core 13, a braking member 11, a brake spring 14, and an electromagnetic magnet 15. The electromagnetic magnet 15 has a brake coil (electromagnetic coil) 16.

ロッド１２は可動鉄心１３と接合されている。また、制動部材１１はロッド１２の先端１２ａ側に取り付けられている。ブレーキばね１４は可動鉄心１３を押圧しており、その結果、可動鉄心１３が取り付けられたロッド１２を介して制動部材１１を被制動体８の外周部８ａに押圧する。   The rod 12 is joined to the movable iron core 13. The braking member 11 is attached to the tip 12 a side of the rod 12. The brake spring 14 presses the movable iron core 13, and as a result, the brake member 11 is pressed against the outer peripheral portion 8 a of the braked body 8 via the rod 12 to which the movable iron core 13 is attached.

そしてブレーキコイル１６に電流を流すことにより、電磁マグネット１５が励磁され、ブレーキ装置９の制動力を解除するための電磁力が発生し、ブレーキばね１４のばね力による押付力に抗して制動部材１１が被制動体８から開離される。また、ブレーキコイル１６への通電を遮断することにより、電磁マグネット１５の励磁が解除され、ブレーキばね１４のばね力により制動部材１１が被制動体８に押圧される。このように制動部材１１は被制動体８の径方向に動作して被制動体８を押圧するように構成されていて、ロッド１２の動作によって被制動体８の外周部８ａに接離可能に構成されている。この際、被制動体８の外周部８ａに作用する制動部材１１の押付力と、押付力を解除する力の両方を、レバー等の減速機構を介さずにロッド１２によって直接伝達する構造となっており、押付力の減速及び伝達機構が不要なため、ブレーキ装置９全体の部品点数減による小型化に対応する構造となっている。   By passing a current through the brake coil 16, the electromagnetic magnet 15 is excited to generate an electromagnetic force for releasing the braking force of the brake device 9, and the braking member resists the pressing force generated by the spring force of the brake spring 14. 11 is separated from the body 8 to be braked. Also, by energizing the brake coil 16, the excitation of the electromagnetic magnet 15 is released, and the braking member 11 is pressed against the braked body 8 by the spring force of the brake spring 14. Thus, the braking member 11 is configured to operate in the radial direction of the braked body 8 to press the braked body 8, and can be brought into and out of contact with the outer peripheral portion 8 a of the braked body 8 by the operation of the rod 12. It is configured. At this time, both the pressing force of the braking member 11 acting on the outer peripheral portion 8a of the braked body 8 and the force for releasing the pressing force are directly transmitted by the rod 12 without using a reduction mechanism such as a lever. In addition, since the pressing force decelerating and transmitting mechanism is unnecessary, the structure of the brake device 9 can be reduced by reducing the number of parts.

ここで、図４において、モーターフレーム１０には、ブレーキ装置９の設置部分からせり出すように、一体化されたガイド１７が設けられている。ガイド１７は被制動体８の回転する方向、つまり、被制動体８は図４で右回り又は左回りに回転するため、被制動体８の回転軸方向から見たときに制動部材１１の左右両端に僅かな隙間を有して、互いに対向して制動部材１１を挟んで設けられている。また本実施形態では、対向するガイド１７の間にブレーキ装置９の設置状態のまま、制動部材１１を巻上機軸方向に脱着及び出し入れを可能とすることを目的とした切欠き部２３がモーターフレーム１０に設けられ、その大きさは制動部材１１を回転軸方向に脱着及び出し入れ可能なものとなっている。   Here, in FIG. 4, the motor frame 10 is provided with an integrated guide 17 so as to protrude from the installation portion of the brake device 9. The guide 17 rotates in the direction in which the braked body 8 rotates, that is, the braked body 8 rotates clockwise or counterclockwise in FIG. There are slight gaps at both ends, and the brake members 11 are sandwiched between the two. Further, in the present embodiment, the notch portion 23 for the purpose of enabling the braking member 11 to be attached / detached / removed in the axial direction of the hoisting machine while the brake device 9 is installed between the opposing guides 17 has the motor frame. The size of the brake member 11 is such that the brake member 11 can be attached to and removed from the rotary shaft.

図５は制動部材が被制動部に接触した直後のブレーキ部分動作説明用の要部拡大図、図６は制動部材が反力受け部材に支持された状態を示すブレーキ部分動作説明用の要部拡大図である。続いて図４，図５，図６より、本発明の一実施例であるエレベーター用巻上機ブレーキ部分の動作を説明する。図４に示すように、制動部材１１が被制動体８から開離された状態、及び電磁マグネット１５の励磁が解除されて制動部材１１が被制動体８の外周部８ａに接触するまでのガイド１７間を被制動体８の径方向に移動している状態においては、制動部材１１とガイド１７の間に力の作用は無い。このように、ガイド１７と制動部材１１の被制動体８の回転方向の両端部の間には、僅かな隙間が設けられており、制動部材１１が動作する際にガイド１７と制動部材１１の間で摩擦が発生することが抑えられる構成となっている。   FIG. 5 is an enlarged view of a main part for explaining the operation of the brake part immediately after the braking member comes into contact with the braked part, and FIG. 6 is a main part for explaining the operation of the brake part showing a state in which the braking member is supported by the reaction force receiving member. It is an enlarged view. Subsequently, the operation of the elevator hoisting machine brake portion according to one embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 4, the state where the braking member 11 is separated from the braked body 8 and the guide until the excitation of the electromagnetic magnet 15 is released and the braking member 11 contacts the outer peripheral portion 8 a of the braked body 8. In a state where the distance between the brake members 11 is moved in the radial direction of the braked body 8, no force acts between the brake member 11 and the guide 17. Thus, a slight gap is provided between both ends of the guide 17 and the braking member 11 in the rotational direction of the brake target body 8, and the guide 17 and the braking member 11 are moved when the braking member 11 is operated. It is the structure which can suppress that friction generate | occur | produces between.

そして、図５に示すように制動部材１１が被制動体８の外周部８ａに接触して押圧されると、被制動体８は回転しているため、その摩擦力によって、制動部材１１は被制動体８の回転方向側、図５に示した例では右に向かって移動させられるような力を受けることになる。   Then, as shown in FIG. 5, when the braking member 11 comes into contact with and presses against the outer peripheral portion 8a of the braked body 8, the braked body 8 is rotated, so that the braking member 11 is driven by the frictional force. In the example shown in FIG. 5 on the rotational direction side of the brake body 8, a force that can be moved toward the right is received.

摩擦力により被制動体８の回転方向側に力を受けた制動部材１１は、本実施例では僅かに制動部材１１が被制動体８の回転方向に向かって移動可能に構成されており、被制動体８の回転方向に移動することで図６に示すように、制動部材１１が被制動体８の回転方向側に位置するガイド１７に接触し、制動部材１１が被制動体８の回転方向側へと移動しようとする動きを、ガイド１７が抑制し、制動部材１１に掛かる被制動体８の回転による摩擦力を負担する構造となっている。つまりガイド１７が、制動部材１１に掛かる被制動体８の回転による摩擦力を負担する反力受け部材を形成している。   The braking member 11 that has received a force in the rotational direction of the braked body 8 due to the frictional force is configured such that the braking member 11 is slightly movable in the rotational direction of the braked body 8 in this embodiment. By moving in the rotational direction of the brake body 8, the braking member 11 comes into contact with the guide 17 positioned on the rotational direction side of the braked body 8 as shown in FIG. 6, and the braking member 11 rotates in the rotational direction of the braked body 8. The movement to move to the side is suppressed by the guide 17 and the frictional force due to the rotation of the braked body 8 applied to the braking member 11 is borne. That is, the guide 17 forms a reaction force receiving member that bears a frictional force due to the rotation of the braked body 8 applied to the braking member 11.

なお、本実施形態では図５及び図６に示すように制動部材１１はロッド１２との接合部に球面座１８が設けられており、摩擦材１９が設置されているシュー２０との間に設けられた隙間によって微小可動となる構造を有している。そして、制動部材１１が被制動体８の外周面８ａに接触した際に摩擦力により被制動体８の回転方向側に力を受けると、球面座１８とシュー２０の相対的な位置が変動することで、僅かに制動部材１１が被制動体８の回転方向に向かって移動することが可能に構成されている。   In this embodiment, as shown in FIGS. 5 and 6, the braking member 11 is provided with a spherical seat 18 at a joint portion with the rod 12 and provided between the shoe 20 on which the friction material 19 is installed. It has a structure that can be moved minutely by the formed gap. When the braking member 11 contacts the outer peripheral surface 8a of the braked body 8 and receives a force on the rotational direction side of the braked body 8 due to a frictional force, the relative positions of the spherical seat 18 and the shoe 20 change. Thus, the braking member 11 is configured to be able to move slightly in the rotational direction of the braked body 8.

また、上述の説明では被制動体８の回転方向が右回りの場合を挙げて説明したが、被制動体８は左回りに回転することもあり、このような場合に制動部材１１が被制動体８の外周部８ａに接触すると制動部材１１は左に向かって移動させられるような力を受ける。そして摩擦力により僅かに左に移動した制動部材１１は図５に示した制動部材１１の左側に位置するガイド１７に接触し、制動部材１１が被制動体８の回転方向側へと移動しようとする動きを、ガイド１７が抑制し、制動部材１１に掛かる被制動体８の回転による摩擦力を負担するのである。   In the above description, the case where the rotation direction of the braked body 8 is clockwise is described. However, the braked body 8 may rotate counterclockwise. In such a case, the braking member 11 is braked. When coming into contact with the outer peripheral portion 8a of the body 8, the braking member 11 receives a force that can be moved toward the left. Then, the braking member 11 slightly moved to the left by the frictional force comes into contact with the guide 17 located on the left side of the braking member 11 shown in FIG. 5, and the braking member 11 tries to move toward the rotational direction side of the braked body 8. The movement which performs is suppressed by the guide 17, and the frictional force by rotation of the to-be-brake body 8 applied to the braking member 11 is borne.

なお、本発明は、上述の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で設計変更可能である。例えば、本実施形態ではモータ６と被制動体８が一体となる構造となっているが、モータ６と被制動体８を別々に設置する構造としても良い。また、ブレーキ装置９の制動力を、レバー等の減速機構を介して被制動体８に伝達する構造とすることも可能である。また、昇降路２２内に設置する薄型タイプの巻上機に限らず、機械室内に設置するタイプの巻上機においても適用可能であり、ブレーキ装置９の設置数も本実施例のように２つではなくその数の増減も可能である。   The present invention is not limited to the above-described embodiment, and the design can be changed without departing from the gist of the present invention. For example, in the present embodiment, the motor 6 and the braked body 8 are integrated, but the motor 6 and the braked body 8 may be separately installed. It is also possible to adopt a structure in which the braking force of the brake device 9 is transmitted to the braked body 8 via a speed reduction mechanism such as a lever. Further, the present invention is not limited to the thin type hoisting machine installed in the hoistway 22, but can be applied to the hoisting machine installed in the machine room, and the number of brake devices 9 installed is 2 as in this embodiment. The number can be increased or decreased instead of one.

また、上述の説明ではガイド１７について、制動部材１１の両側に分離した構造となっているが、ガイド１７が完全に分離している必要は無く、一部が補強部により繋がっている構造や、図７に示すように、対向するガイド１７の間を補強部２４にて接続して窓状の切欠き部２１を設けた構造としても良い。   In the above description, the guide 17 has a structure separated on both sides of the braking member 11, but the guide 17 does not have to be completely separated, and a structure in which a part is connected by a reinforcing portion, As shown in FIG. 7, a structure may be adopted in which window-shaped notches 21 are provided by connecting the opposing guides 17 with a reinforcing portion 24.

以上のように本発明に係る巻上機は、ブレーキ装置９を、被制動体８の外周部に対向してモーターフレーム１０に配設し、さらにモーターフレーム１０に一体化された反力受け部材であるガイド１７を設けたことにより、ブレーキ装置９の制動部材１１が被制動体８の回転方向側へ移動しようとするのを、ガイド１７が抑制する働きを有するため、被制動体８の回転方向側に発生する摩擦反力は、ロッド１２ではなくガイド１７が負担することとなる。そのため従来の、制動時に被制動体８の回転方向に発生する摩擦反力をブレーキ本体で負担する構造を有する巻上機と比較して、ブレーキ装置９自身が被制動体８の回転方向の摩擦力に耐え得る強度を確保する必要が無いため、ブレーキ本体の負担が低減されることで大幅な小型化を実現でき、巻上機全体の省スペース化に対応することができる。   As described above, in the hoist according to the present invention, the brake device 9 is disposed on the motor frame 10 so as to face the outer peripheral portion of the braked body 8, and the reaction force receiving member integrated with the motor frame 10. By providing the guide 17, the guide 17 has a function of suppressing the braking member 11 of the brake device 9 from moving toward the rotational direction of the braked body 8. The friction reaction force generated on the direction side is borne not by the rod 12 but by the guide 17. Therefore, compared with the conventional hoisting machine having a structure in which the brake body bears the frictional reaction force generated in the rotation direction of the braked body 8 during braking, the brake device 9 itself has friction in the rotation direction of the braked body 8. Since it is not necessary to secure the strength that can withstand the force, the load on the brake body can be reduced, so that significant downsizing can be realized, and the entire hoisting machine can be saved in space.

また、ガイド１７をモーターフレーム１０に一体化することにより、ブレーキ装置９に新たな部品を追加することなくガイド効果が得られるため、反力受け用の部品を別に取り付けた場合に比べて部品点数を少なくできる。   Further, by integrating the guide 17 with the motor frame 10, a guide effect can be obtained without adding new parts to the brake device 9. Therefore, the number of parts can be increased compared to the case where the reaction force receiving parts are separately attached. Can be reduced.

また、制動部材１１を巻上機軸方向に脱着可能とすることを目的とした切欠き部２３や窓状切欠き部２１等を、モーターフレーム１０に設けた構造とすることで、制動部材１１の交換の際にブレーキ装置９をモーターフレーム１０から取り外す事無く、制動部材１１を脱着することができる。また、制動部材１１の磨耗状態をブレーキ装置９の設置状態のまま確認することもできるため、メンテナンス性に優れた巻上機とすることができる。   Further, by providing the motor frame 10 with a notch 23, a window-like notch 21, etc. for the purpose of making the brake member 11 detachable in the hoisting machine axial direction, The brake member 11 can be attached and detached without removing the brake device 9 from the motor frame 10 at the time of replacement. Moreover, since it is also possible to check the worn state of the braking member 11 with the brake device 9 installed, the hoisting machine excellent in maintainability can be obtained.

また、ガイド１７と制動部材１１の被制動体８の回転方向の両端部の間には、僅かな隙間が設けられており、制動部材１１が動作する際にガイド１７と制動部材１１の間で摩擦が発生しないので、ブレーキ装置９の開離及び制動動作が妨げられることや、制動部材１１とガイド１７の間での摩擦により制動部材１１が摩耗してしまうようなことが無い。従ってこのような点からもメンテナンスの頻度を低減することができ、メンテナンス性を向上させることができる。   In addition, a slight gap is provided between both ends of the guide 17 and the braking member 11 in the rotational direction of the braked body 8, and the guide 17 and the braking member 11 are moved when the braking member 11 is operated. Since no friction is generated, there is no possibility that the braking and braking operation of the brake device 9 is hindered or the braking member 11 is worn by friction between the braking member 11 and the guide 17. Therefore, also from such a point, the frequency of maintenance can be reduced and the maintainability can be improved.

さらに、上述のような巻上機を使用したエレベーターによれば、効率的なレイアウトひいては省スペース化が可能なエレベーター装置を提供することができる。   Furthermore, according to the elevator using the hoist as described above, it is possible to provide an elevator device capable of efficient layout and space saving.

また、本実施形態における巻上機４は、ブレーキ装置９が被制動体８の外周円周面に対向して上下に一対備えられている。昇降路内に巻上機４を設置する場合、昇降路は縦長形状のため、横方向の大きさには非常に制限が大きいが、縦方向には比較的余裕がある。従って、巻上機４の上下にブレーキ装置９を一対備える構成は、より効率的なレイアウトひいては省スペース化に貢献する。   Further, in the hoisting machine 4 in the present embodiment, a pair of brake devices 9 are provided on the upper and lower sides so as to face the outer circumferential surface of the braked body 8. When installing the hoisting machine 4 in the hoistway, the hoistway is vertically long, so the size in the horizontal direction is very limited, but there is a relative margin in the vertical direction. Therefore, the configuration including a pair of brake devices 9 on the upper and lower sides of the hoisting machine 4 contributes to a more efficient layout and space saving.

そして、このような巻上機４は機械室内ではなく、昇降路２２内に配置されることで、その巻上機のメンテナンス性能を十分に発揮するとともに効率的なレイアウト及び省スペース化への十分な貢献を果たすものとすることが可能となり、エレベーター装置全体の性能に大きく寄与するものとできる。   Such a hoisting machine 4 is arranged not in the machine room but in the hoistway 22, so that the hoisting machine can sufficiently exhibit the maintenance performance and is sufficient for efficient layout and space saving. Can contribute greatly to the performance of the entire elevator apparatus.
