Description

この発明は、かご及び釣合おもりを昇降させる駆動装置が昇降路の上部に配置されたエレベータ装置に関するものである。   The present invention relates to an elevator apparatus in which a drive device for raising and lowering a car and a counterweight is arranged at the upper part of a hoistway.

従来、昇降路の高さ寸法の短縮化のために、昇降路の上部に巻上機を水平に配置したエレベータ装置が提案されている。巻上機の駆動綱車の回転軸は、水平面に対して垂直となっている。駆動綱車には、主索が水平に巻き掛けられている。昇降路の上部には、主索の方向を水平方向から鉛直方向へ転向する２つの転向綱車が設けられている。かご及び釣合おもりは、転向綱車により転向された主索により昇降路内に吊り下げられている（特許文献１参照）。   Conventionally, in order to shorten the height dimension of the hoistway, an elevator apparatus in which a hoisting machine is horizontally arranged on the upper part of the hoistway has been proposed. The axis of rotation of the hoist drive sheave is perpendicular to the horizontal plane. A main rope is wound around the driving sheave horizontally. Two turning sheaves that change the direction of the main rope from the horizontal direction to the vertical direction are provided at the upper part of the hoistway. The car and the counterweight are suspended in the hoistway by the main rope turned by the turning sheave (see Patent Document 1).

このようなエレベータ装置では、かご１及び釣合おもり３が第１及び第２駆動装置１２，１３の駆動力により昇降路１内を昇降されるようになっており、かつ、かご２及び釣合おもり３は、第１主ロープ１９及び第２主ロープ２０により、２：１ローピング方式で昇降路１内に吊り下げられているので、第１及び第２駆動装置１２，１３に与えられる負荷を軽減することができ、第１及び第２駆動装置１２，１３を小形化することができる。これにより、昇降路１の高さ方向の長さを短くすることができ、また昇降路１の水平断面積を小さくするができる。従って、エレベータ装置全体の縮小化を図ることができる。また、エレベータ装置の大容量化に伴うエレベータ装置の大形化の度合いを小さくすることができる。   In such an elevator apparatus, the car 1 and the counterweight 3 are moved up and down in the hoistway 1 by the driving force of the first and second drive units 12 and 13, and the car 2 and the counterweight Since the weight 3 is suspended in the hoistway 1 by the first main rope 19 and the second main rope 20 in the 2: 1 roping method, the load applied to the first and second drive units 12 and 13 is reduced. This can be reduced, and the first and second driving devices 12 and 13 can be reduced in size. Thereby, the length of the hoistway 1 in the height direction can be shortened, and the horizontal sectional area of the hoistway 1 can be reduced. Therefore, the whole elevator apparatus can be reduced. Moreover, the degree of size increase of the elevator device accompanying the increase in capacity of the elevator device can be reduced.

また、第１及び第２主ロープ１９，２０を吊り車２５〜３０へそれぞれ導く返し車３１〜３４が昇降路１の上部に設けられているので、ほぼ水平に延びる第１及び第２主ロープ１９，２０をほぼ垂直方向へ方向転換させることができ、かご２及び釣合おもり３に干渉することなく、第１及び第２駆動シーブ１９，２０から返し車３１〜３４へ第１及び第２主ロープ１９，２０を導くことができる。   Moreover, since the return wheels 31-34 which guide the 1st and 2nd main ropes 19 and 20 to the suspension vehicles 25-30, respectively, are provided in the upper part of the hoistway 1, the first and second main ropes extending substantially horizontally.

Thereby, the driving force of the 1st drive device 12 can be transmitted to the 1st main rope 19 more reliably, and the cage | basket | car 2 and the counterweight 3 can be raised / lowered more reliably.

また、第２主ロープ２０の第２駆動シーブ１７と第２かご側返し車３３との間の部分が巻き掛けられる第２転向シーブ３６が昇降路１内の上部に配置されているので、第２主ロープ２０の第２駆動シーブ１７及び第２転向シーブ３６に対する巻き付け角を確保することができ、トラクション能力を増加させることができる。これにより、第２駆動装置１３の駆動力を第２主ロープ２０へより確実に伝達することができ、かご２及び釣合おもり３をより確実に昇降させることができる。   Further, since the second turning sheave 36 around which the portion of the second main rope 20 between the second drive sheave 17 and the second car side return wheel 33 is wound is disposed in the upper part in the hoistway 1, The winding angle with respect to the 2nd drive sheave 17 and the 2nd turning sheave 36 of the 2 main ropes 20 can be ensured, and traction capability can be increased. Thereby, the driving force of the 2nd drive device 13 can be transmitted to the 2nd main rope 20 more reliably, and the cage | basket | car 2 and the counterweight 3 can be raised / lowered more reliably.

また、昇降路１の垂直投影面において、第１及び第２駆動装置１２，１３は、かご２の領域内に配置されているので、昇降路１の水平断面積をさらに小さくすることができ、エレベータ装置全体の縮小化をさらに図ることができる。   Further, since the first and second driving devices 12 and 13 are arranged in the area of the car 2 on the vertical projection plane of the hoistway 1, the horizontal sectional area of the hoistway 1 can be further reduced. The entire elevator device can be further reduced.
