The machine base 3 is provided with a pair of short frames 4 arranged at intervals in the longitudinal direction of the support beams 2 and installed between the support beams 2, and fixed between these short frames 4 and parallel to the support beams 2. And a pair of long frames 5 extending therefrom. The machine base 3 supports a drive device (hoist) 6. The driving device 6 includes a driving device main body 7 including a motor and a brake unit, and a driving sheave 8 rotated by the driving device main body 7. Further, the driving device 6 is disposed below the machine base 3 so as to be located between the support beams 2. Specifically, the drive device main body 7 is fixed to the lower surface of the long frame 5. The lower end of the driving device 6 is located below the support beam 2. Further, a rotatable deflector 9 is supported on the machine base 3. The deflecting wheel 9 is disposed above the machine base 3 so as to be positioned diagonally above the drive sheave 8. A plurality of vibration isolating members 10 (for example, rubber rubber) for reducing vibration of the driving device 6 transmitted to the supporting beam 2 are interposed between the supporting beam 2 and the machine base 3. .
駆動シ一ブ 8及びそらせ車 9には、 複数本の主索 1 1がダブルラップ方式 （フ ルラップ方式） で卷き掛けられている。 主索 1 1の一端部には、 かご 1 2が吊り 下げられている。 主索 1 1の他端部には、 釣合おもり 1 3が吊り下げられている。 即ち、 かご 1 2及び釣合おもり 1 3は、 1 ： 1口一ビング方式により昇降路 1内 に吊り下げられている。  A plurality of main cables 11 are wound around the drive sheave 8 and the deflector wheel 9 in a double wrap system (full wrap system). A car 12 is suspended from one end of the main rope 11. A counterweight 13 is suspended from the other end of the main rope 11. That is, the car 12 and the counterweight 13 are suspended in the hoistway 1 by the one-by-one bing method.
昇降路 1内には、 かご 1 2の昇降を案内する一対のかごガイ ドレール 1 4、 及 び釣合おもり 1 3の昇降を案内する一対の釣合おもりガイ ドレール 1 5が設置さ れている。 一方のかごガイ ドレール 1 4には、 駆動装置 6の駆動を制御する制御 盤 1 6が取り付けられている。  In the hoistway 1, a pair of car guide rails 14 for guiding the elevator of the car 12 and a pair of counterweight guide rails 15 for guiding the lifting of the counterweight 13 are provided. . A control panel 16 for controlling the driving of the driving device 6 is attached to one of the car guide rails 14.
駆動装置 6及び制御盤 1 6の周囲には、 駆動装置 6及び制御盤 1 6の保守作業 を行うための駆動装置保守スペース及び制御盤保守スペースが確保されている。 制御盤 1 6は、 制御盤保守スペースが駆動装置保守スペースよりも低い位置に位 置するように配置されている。 即ち、 制御盤 1 6は、 制御盤保守スペースが駆動 装置保守スペースに干渉しないように配置されている。  A drive device maintenance space and a control panel maintenance space for performing maintenance work on the drive device 6 and the control panel 16 are secured around the drive device 6 and the control panel 16. The control panel 16 is arranged such that the control panel maintenance space is lower than the drive device maintenance space. That is, the control panel 16 is arranged so that the control panel maintenance space does not interfere with the drive device maintenance space.
次に、 図 3は図 1と同様のエレべ一夕装置の保守作業時の状態を示す側面図で ある。 保守作業時には、 作業員がかご 1 2上に乗り、 かご 1 2上から駆動装置 6 に対する保守作業を行う。 また、 制御盤 1 6に対する保守作業は、 図 3の位置か らかご 1 2を少し下降させ、 かご 1 2上から行う。  Next, FIG. 3 is a side view showing the same state of the elevator apparatus as in FIG. 1 during maintenance work. At the time of maintenance work, a worker rides on the car 12 and performs maintenance work on the drive device 6 from the car 12. In addition, maintenance work on the control panel 16 is performed from above the car 12 by slightly lowering the car 12 from the position shown in FIG.
このようなエレべ一夕装置、 即ち機械室レスエレべ一夕では、 昇降路 1内の上 部に一対の支持梁 2を固定し、 支持梁 2上には、 駆動装置 6及びそらせ車 9を支 持する機械台 3を固定し、 駆動装置 6は、 支持梁 2間に位置するように機械台 3 の下部に配置したので、 垂直投影面内で駆動装置 6を昇降路 1のほぼ中央に配置 することができ、 かご 1 2をその上部の中央で吊ることができる。 従って、 かご In such an elevator system, that is, a machine room-less elevator system, a pair of support beams 2 is fixed to the upper part of the hoistway 1, and a driving device 6 and a deflector 9 are mounted on the support beams 2. The supporting machine base 3 is fixed, and the driving device 6 is arranged at the lower part of the machine base 3 so as to be located between the supporting beams 2.Therefore, the driving device 6 is located almost at the center of the hoistway 1 in the vertical projection plane. The car 12 can be suspended in the center of its upper part. Therefore, the basket
1 2の下部にかご吊り車を設ける必要はなく、 主索 1 1の配置経路を短くするこ とができ、 全体のレイアウトを簡単にすることができる。 また、 昇降路 1の壁部 1 aに支持梁 2の両端部を支持する梁受部 l bを設けた ので、 支持梁 2をより安定して支持することができる。 また、 かごガイ ドレール 1 4及び釣合おもり 1 5により支持梁 2を支持する場合と比べて、 ガイ ドレール 1 4 , 1 5の強度を低下させることができるとともに、 支持梁 2やガイ ドレール 1 4， 1 5のレイアウトの自由度を高めることができる。 There is no need to provide a car suspension wheel at the lower part of 12, and the arrangement route of the main rope 11 can be shortened, and the overall layout can be simplified. Further, since the beam receiving portions lb for supporting both ends of the support beam 2 are provided on the wall 1a of the hoistway 1, the support beam 2 can be more stably supported. Further, the strength of the guide rails 14 and 15 can be reduced as compared with the case where the support beams 2 are supported by the car guide rails 14 and the counterweights 15, and the support beams 2 and the guide rails 14 can be reduced. , 15 The layout flexibility can be increased.
さらに、 主索 1 1が駆動シーブ 8及びそらせ車 9にダブルラップ方式で巻き掛 けられているので、 駆動シ一ブ 8に対する主索 1 1の合計の巻き付け角度を 1 8 0度以上にすることができ、 十分なトラクシヨン能力を確保することができる。 さらにまた、 駆動装置 6は機械台 3の下部に配置されており、 駆動装置 6の下 端部は支持梁 2よりも下方に位置しているので、 図 3に示すように、 駆動装置 6 の保守作業をかご 1 2上から容易に行うことができる。  Further, since the main rope 11 is wound around the drive sheave 8 and the deflector wheel 9 in a double wrap manner, the total winding angle of the main rope 11 around the drive sheave 8 is set to 180 degrees or more. And sufficient traction capability can be ensured. Furthermore, since the driving device 6 is arranged below the machine base 3 and the lower end of the driving device 6 is located below the support beam 2, as shown in FIG. Maintenance work can be easily performed from the car 12.
また、 そらせ車 9は、 駆動シーブ 8の斜め上方に位置するように機械台 3の上 側に配置されているので、 図 3に示すように、 駆動シーブ 8及びそらせ車 9が近 接して配置され、 かつそれらの径が大きい場合であっても、 互いに干渉すること なく駆動シーブ 8及びそらせ車 9を容易に配置することができ、 かご 1 2をその 上部の中央で吊ることができる。  Further, since the deflecting wheel 9 is disposed on the upper side of the machine base 3 so as to be located diagonally above the driving sheave 8, as shown in FIG. 3, the driving sheave 8 and the deflecting wheel 9 are disposed close to each other. Therefore, even when the diameters are large, the drive sheave 8 and the deflector wheel 9 can be easily arranged without interfering with each other, and the car 12 can be hung at the center of the upper part thereof.
