　エレベーターの保守時には建物内の乗り場から整風カバー下部８ａに設けられた乗り込み口９を開け、かご室５の上部に乗り込み作業をするが、整風カバー屋根部８ｂと干渉し、作業効率が悪い。しかし、図２に示すように整風カバー屋根部８ｂを上方にスライドさせることにより、頭上のスペースを確保でき保守時の作業性が向上するという効果が得られる。 During maintenance of the elevator, the entrance 9 provided in the lower part 8a of the rectification cover is opened from the platform inside the building, and work is carried out by entering the upper part of the car room 5, but it interferes with the roof part 8b of the rectification cover, and work efficiency is poor. However, by sliding the rectifying cover roof portion 8b upward as shown in FIG. 2, an overhead space can be secured and the effect of improving workability during maintenance can be obtained.
　整風カバー屋根部８ｂがスライドする仕組みおよび動作について図３を用いて説明をする。図３はＸ－Ｚ平面から見た整風カバー内部の駆動部を示す図である。 The mechanism and operation of sliding the wind rectification cover roof portion 8b will be described with reference to FIG. FIG. 3 is a diagram showing the drive section inside the rectification cover viewed from the XZ plane.
　図３に示すように整風カバー８の内部には支柱１０および駆動部１００を備えている。支柱１０は、一端を整風カバー屋根部８ｂと固定し、整風カバー下部８ａの内側においてかご室５の昇降する方向に２本間隔をあけて配置されている。 As shown in FIG. 3, the rectifying cover 8 is provided with a column 10 and a drive unit 100 inside. One end of the struts 10 is fixed to the rectification cover roof portion 8b, and two pillars 10 are arranged inside the rectification cover lower portion 8a in the direction in which the car chamber 5 ascends and descends with an interval therebetween.
　駆動部１００は、ガイド１１、連結部１２、ウインチ１３、ハンドル１４、ロープ１５、プーリー１６および固定端１７を備える。駆動部１００は整風カバー下部８ａの内部に設けられ、支柱１０をかご室５の昇降する方向に可動させ、支柱１０と連動して整風カバー屋根部８ｂを可動させる。 The driving part 100 includes a guide 11, a connecting part 12, a winch 13, a handle 14, a rope 15, a pulley 16 and a fixed end 17. The drive unit 100 is provided inside the air regulating cover lower part 8a, moves the support 10 in the direction in which the car chamber 5 is raised and lowered, and moves the air regulating cover roof part 8b in conjunction with the support 10. As shown in FIG.
　連結部１２は、支柱１０の下端を連結し２本の支柱１０が平行に保てるように設けられている。連結部１２の両端には一対の第１のプーリー１６ａが設けられ動力の伝達を行う。 The connecting part 12 is provided so as to connect the lower ends of the supports 10 and keep the two supports 10 parallel. A pair of first pulleys 16a are provided at both ends of the connecting portion 12 to transmit power.
　ガイド１１はかご枠７の上梁７ａに固定され筒状を有し、かご室５が昇降する方向に支柱１０が可動することを規制する。例えば図３に示すように支柱１０は上梁７ａに固定されたガイド１１の内周側に配置されている。なお、ガイド１１は例えばブッシュなどを用いるが、これに限定せず支柱１０の可動する方向を規制できるものであれば種類を問わない。 The guide 11 is fixed to the upper beam 7a of the car frame 7 and has a tubular shape, and restricts the movement of the support 10 in the direction in which the car room 5 is raised and lowered. For example, as shown in FIG. 3, the strut 10 is arranged on the inner peripheral side of the guide 11 fixed to the upper beam 7a. Although a bush or the like is used as the guide 11, the guide 11 is not limited to this and may be of any type as long as it can regulate the direction in which the column 10 moves.
　かご枠７の上梁７ａにはさらにウインチ１３、第２のプーリー１６ｂおよび固定端１７が設けられている。第２のプーリー１６ｂは上梁７ａにおいてガイド１１を隔ててウインチ１３とは反対側に配置され、動力の伝達を行う。固定端１７は上梁７ａにおいて第２のプーリー１６ｂを隔ててガイド１１とは反対側に設けられている。 The upper beam 7a of the car frame 7 is further provided with a winch 13, a second pulley 16b and a fixed end 17. The second pulley 16b is arranged on the side of the upper beam 7a opposite to the winch 13 across the guide 11, and transmits power. The fixed end 17 is provided on the side of the upper beam 7a opposite to the guide 11 across the second pulley 16b.
　またロープ１５は、一端を固定端１７に固定され、一対の第１のプーリー１６ａおよび第２のプーリー１６ｂを介して他端をウインチ１３と接続されている。ウインチ１３はロープ１５を巻き取ることにより整風カバー屋根部８ｂをかご室５の昇降する方向に可動させる。 One end of the rope 15 is fixed to the fixed end 17, and the other end is connected to the winch 13 via a pair of first pulley 16a and second pulley 16b. The winch 13 winds the rope 15 to move the rectifying cover roof portion 8b in the direction in which the car chamber 5 is raised and lowered.
　続いて整風カバー屋根部８ｂの動作について説明をする。ウインチ１３に接続されたハンドル１４を時計方向に回転させると、ロープ１５がウインチ１３に巻き取られ、整風カバー屋根部８ｂ、支柱１０、連結部１２および一対の第１のプーリー１６ａが上方に持ち上がる。すなわち、整風カバー屋根部８ｂはかご室５の上昇する方向に可動する。 Next, the operation of the rectification cover roof portion 8b will be explained. When the handle 14 connected to the winch 13 is rotated clockwise, the rope 15 is wound around the winch 13, and the rectification cover roof portion 8b, the strut 10, the connection portion 12 and the pair of first pulleys 16a are lifted upward. . That is, the rectification cover roof portion 8b moves in the direction in which the car room 5 rises.
　一方ハンドル１４を反時計方向に回転させると、ウインチ１３に巻き取られていたロープ１５がもとに戻り、整風カバー屋根部８ｂ、支柱１０、連結部１２および一対の第１のプーリー１６ａが下方に下がる。すなわち、整風カバー屋根部８ｂはかご室５の下降する方向に可動する。 On the other hand, when the handle 14 is rotated counterclockwise, the rope 15 wound around the winch 13 returns to its original position, and the rectification cover roof portion 8b, the strut 10, the connecting portion 12 and the pair of first pulleys 16a move downward. go down to That is, the rectification cover roof portion 8b moves in the direction in which the car chamber 5 descends.
　保守時に整風カバー屋根部８ｂ、支柱１０、連結部１２および一対の第１のプーリー１６ａを上方に持ち上げたまま作業を行うと、整風カバー屋根部８ｂの自重により下方に下がってくる可能性がある。そのため支柱１０に穴をあけ、穴にピンを挿入するなどして、落下防止の対策をするとなおよい。また、ウインチ１３およびハンドル１４は上梁７ａにおいて建物内の乗り場側にあると、保守時に作業者がかご室５の上部に乗り込んですぐに整風カバー屋根部８ｂを持ち上げることができるため、さらに作業性が向上する。 If maintenance work is performed while the rectification cover roof portion 8b, the strut 10, the connecting portion 12, and the pair of first pulleys 16a are lifted upward, the rectification cover roof portion 8b may come down due to its own weight. . Therefore, it is better to make a hole in the post 10 and insert a pin into the hole to prevent it from falling. In addition, if the winch 13 and the handle 14 are located on the landing side of the building on the upper beam 7a, the operator can get into the upper part of the car room 5 and immediately lift the wind regulating cover roof part 8b during maintenance. improve sexuality.
　以上より本実施の形態にかかるエレベーターは、整風カバー８を備え整風カバー８の内部に駆動部１００を配置している。この構成によりエレベーター昇降時の騒音を抑制し、また保守時の作業性を向上させるという効果を得る。 As described above, the elevator according to the present embodiment is provided with the rectifying cover 8 and the driving section 100 is arranged inside the rectifying cover 8 . With this configuration, it is possible to suppress noise when the elevator is ascending and descending, and to improve workability during maintenance.
　なお、本実施の形態には支柱１０およびガイド１１をそれぞれ２本配置した例を示したが支柱１０およびガイド１１の数はこれに限定しない。支柱１０およびガイド１１はそれぞれ１本でも成立するが、モーメントなどが発生した際に、部分的に負荷が集中することから、支柱１０およびガイド１１は複数本あることが望ましい。 Although an example in which two columns 10 and two guides 11 are arranged is shown in this embodiment, the number of columns 10 and guides 11 is not limited to this. Even if there is only one strut 10 and one guide 11 , it is preferable to have a plurality of struts 10 and guides 11 because the load is partially concentrated when a moment or the like is generated.
