本発明はエレベータ装置に係り、特に、保守作業を行なうときに、かごが昇降しないようにかごを昇降路内に固定する固定装置を備えているものに好適なエレベータ装置に関する。   The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus suitable for an apparatus having a fixing device for fixing a car in a hoistway so that the car does not move up and down when maintenance work is performed.

一般に、エレベータ装置には、その保守を行う作業員がかご上に乗って作業を行なうときにかごが昇降しないように、かごを昇降路内に固定する固定装置を備えている。このエレベータの固定装置の一例として、例えば、特許文献１に記載のものを挙げることができる。   Generally, an elevator apparatus is provided with a fixing device that fixes a car in a hoistway so that the car does not move up and down when an operator who performs maintenance works on the car. As an example of this elevator fixing device, for example, the one described in Patent Document 1 can be cited.

上述した固定装置を備えた従来のエレベータ装置を図１１乃至図１３に示す。   The conventional elevator apparatus provided with the fixing device mentioned above is shown in FIG. 11 thru | or FIG.

該図に示す如く、固定装置を備えた従来のエレベータ装置は、昇降路１００内に立設されたかご用ガイドレール１０１と、このかご用ガイドレール１０１に沿って昇降するかご１０２とを有すると共に、かご１０２が昇降しないように、かご１０２を昇降路１００内に固定する固定装置１０３として、かご用ガイドレール１０１に取付けられた固定板１０４と、かご１０２に設けられ、固定板１０４に係合する係合位置と固定板１０４に係合しない非係合位置とに移動可能なロッド１０５とを備えており、エレベータ装置の保守の際に、作業員がかご１０２上に乗って作業を行なうときに、ロッド１０５を前進位置として固定板１０４に係合させ、かご１０２を昇降路１００内に固定するようになっている。   As shown in the figure, a conventional elevator apparatus provided with a fixing device has a car guide rail 101 erected in the hoistway 100 and a car 102 that moves up and down along the car guide rail 101. As the fixing device 103 for fixing the car 102 in the hoistway 100 so that the car 102 does not move up and down, the fixing plate 104 attached to the car guide rail 101 and the car 102 are provided and engaged with the fixing plate 104.

特開２０１４−６１９６８号公報JP 2014-61968 A

ところで、エレベータ装置として、かご用ガイドレール１０１の昇降路１００の頂部近傍に頂上ビーム１０６が架設され、この頂上ビーム１０６に主ロープを駆動する巻上機１０７が設置されたものがあり、このようなエレベータ装置にあっては、かご用ガイドレール１０１の昇降路１００の頂部近傍は、頂上ビーム１０６を支持するビーム受け１０８等の部品が設置されている。   By the way, as an elevator apparatus, there is one in which a top beam 106 is installed near the top of the hoistway 100 of the car guide rail 101, and a hoisting machine 107 for driving a main rope is installed on the top beam 106. In such an elevator apparatus, parts such as a beam receiver 108 for supporting the top beam 106 are installed near the top of the hoistway 100 of the car guide rail 101.

しかしながら、前述した特許文献１に記載されたエレベータ装置の固定装置のように、かご用ガイドレール１０１側に固定装置１０３の固定板１０４、かご１０２側に固定板１０４に係合可能なロッド１０５を設けたものでは、ビーム受け１０８等の部品との兼ね合いから、固定板１０４の取付け位置を低くせざるをえず、固定装置１０３によりかご１０２を昇降路１００内に固定したときに、作業場となるかご１０２上の高さ位置が保守作業の対象となる巻上機１０７から離れてしまい、保守作業が行いにくいという課題があった。   However, like the fixing device of the elevator apparatus described in Patent Document 1 described above, the fixing plate 104 of the fixing device 103 is provided on the side of the car guide rail 101, and the rod 105 that can be engaged with the fixing plate 104 is provided on the side of the car 102. In the provided one, the work place becomes when the car 102 is fixed in the hoistway 100 by the fixing device 103 because the mounting position of the fixing plate 104 must be lowered due to the balance with the parts such as the beam receiver 108. There is a problem that the height position on the car 102 is separated from the hoisting machine 107 to be subjected to the maintenance work, and the maintenance work is difficult to perform.

即ち、主ロープを駆動する巻上機１０７が設置された頂上ビーム１０６を支持するビーム受け１０８の下に固定装置１０３が配置されることから、作業場となるかご１０２上の高さ位置が保守作業の対象となる巻上機１０７から離れてしまうので、保守作業が行いにくくなってしまう。特に、図示したような積載質量が重いエレベータ装置に設置される巻上機１０７は、ブレーキの数も増やす必要があるため、比較的大きな高さ寸法を有しており、この課題が顕著なものとなる。   That is, since the fixing device 103 is disposed under the beam receiver 108 that supports the top beam 106 on which the hoisting machine 107 that drives the main rope is installed, the height position on the car 102 serving as a work place is the maintenance work. This makes it difficult to perform maintenance work. In particular, the hoisting machine 107 installed in an elevator apparatus having a heavy load mass as shown in the figure has a relatively large height because it is necessary to increase the number of brakes, and this problem is remarkable. It becomes.

本発明は上述の点に鑑みなされたもので、その目的とするところは、保守作業時に、かごをより高い位置で固定することができ、保守作業性の向上を図ったエレベータ装置を提供することにある。   The present invention has been made in view of the above points, and an object thereof is to provide an elevator apparatus capable of fixing a car at a higher position during maintenance work and improving maintenance workability.

また、固定部１５は、ロッド１４が挿通可能な孔１７ａが形成されている筐体１７と、この筐体１７の孔１７ａに、ロッド１４が挿通された状態でロッド１４に螺合されるナット１８とを有している。   The fixing portion 15 includes a housing 17 in which a hole 17a into which the rod 14 can be inserted is formed, and a nut that is screwed into the rod 14 in a state where the rod 14 is inserted into the hole 17a of the housing 17. 18.

更に、本実施例の固定装置１２には、ナット１８を受ける落下防止体１９が設けられている。   Furthermore, the fixing device 12 of this embodiment is provided with a fall prevention body 19 that receives the nut 18.

この落下防止体１９は、断面Ｌ字状に形成された板であり、かご４の通常運転時には、図４に点線で示すように、固定部１５に、例えば、図示しないボルトにより装着された状態で収納されている。この状態で落下防止体１９は、かご４の投影面積外にその一部が位置するが、この出張り量は限られたものであり、かご４の昇降に支障をきたすものではない。   The fall prevention body 19 is a plate formed in an L-shaped cross section, and when the car 4 is in normal operation, as shown by a dotted line in FIG. It is stored in. In this state, a part of the fall prevention body 19 is located outside the projected area of the car 4, but the amount of this protrusion is limited and does not hinder the raising and lowering of the car 4.

一方、かご４の固定時には、落下防止体１９を一旦固定部１５から取外すと共に、図４に実線で示すように、落下防止体１９の一端１９ａを固定部１５の端部に前述したボルトにより取付け、落下防止体１９の受け部１９ｂを筐体１７の下方に延在するようにし、ナット１８が落下したときに、落下防止体１９の受け部１９ｂで受けることができるようになっている。   On the other hand, when the car 4 is fixed, the fall prevention body 19 is once removed from the fixing portion 15, and one end 19a of the fall prevention body 19 is attached to the end of the fixing portion 15 with the bolt described above as shown by a solid line in FIG. The receiving portion 19b of the fall prevention body 19 extends below the housing 17, and can be received by the receiving portion 19b of the fall prevention body 19 when the nut 18 is dropped.

図５は、本実施例のエレベータ装置に採用される固定装置１２によるかご４の固定手順を示し、固定装置１２によるかご４の固定前の説明図、図６は、本実施例のエレベータ装置に採用される固定装置１２によるかご４の固定手順を示し、固定装置１２によるかご４の固定後の説明図、図７は、本実施例のエレベータ装置に採用される固定装置１２によるかご４の固定状態を示す図１に相当する図である。   FIG. 5 shows a procedure for fixing the car 4 by the fixing device 12 employed in the elevator apparatus of the present embodiment. FIG. 5 is an explanatory diagram before the car 4 is fixed by the fixing apparatus 12, and FIG. 6 shows the elevator apparatus of the present embodiment. FIG. 7 shows a procedure for fixing the car 4 by the fixing device 12 employed, and is an explanatory view after the car 4 is fixed by the fixing device 12, and FIG. 7 shows the fixing of the car 4 by the fixing device 12 employed in the elevator apparatus of the present embodiment. It is a figure equivalent to FIG. 1 which shows a state.

本実施例のエレベータ装置にあっては、かご４の通常運転時には、固定装置１２の固定部１５は非係合位置にあってかご４の投影面積内に位置しており、かご４の昇降に支障をきたすことはない。また、固定部１５には前述したように、落下防止体１９が装着された状態で収納されている。この状態で落下防止体１９は、かご４の投影面積外にその一部が位置するが、この出張り量は限られたものであり、かご４の昇降に支障をきたすものではない。   In the elevator apparatus of the present embodiment, during the normal operation of the car 4, the fixing portion 15 of the fixing apparatus 12 is in the non-engagement position and is located within the projected area of the car 4. There will be no hindrance. Further, as described above, the fixing portion 15 is accommodated in a state in which the fall prevention body 19 is mounted. In this state, a part of the fall prevention body 19 is located outside the projected area of the car 4, but the amount of this protrusion is limited and does not hinder the raising and lowering of the car 4.

一方、例えば、頂部ビーム１０に設置される巻上機１１の保守作業を行う場合、作業員はかご４上に乗り込み、かご４を昇降路１の頂部近傍に位置させる。そして、図５に示すように、固定装置１２の固定部１５を、例えば、手動にて係合位置とし、かご４の投影面積外に出張らせる。   On the other hand, for example, when performing maintenance work of the hoisting machine 11 installed on the top beam 10, the worker gets on the car 4 and positions the car 4 in the vicinity of the top of the hoistway 1. And as shown in FIG. 5, the fixing | fixed part 15 of the fixing device 12 is made into an engagement position manually, for example, and is made a business trip out of the projection area of the cage | basket | car 4. As shown in FIG.

また、落下防止体１９を一旦固定部１５から取外し、次いで、落下防止体１９の一端１９ａを固定部１５の端部にボルトにより取付け、落下防止体１９の受け部１９ｂを筐体１７の下方に延在させる。次いで、かご４を低速で上昇させ、ロッド１４を筐体１７の孔１７ａに挿通する。挿通が完了するとかご４を停止し、図４、図６及び図７に示すように、ナット１８をロッド１４に螺合する。このとき、作業員が万一、ナット１８を落としても、落下防止体１９により受けることができる。   Further, the fall prevention body 19 is once removed from the fixing portion 15, and then one end 19 a of the fall prevention body 19 is attached to the end of the fixing portion 15 with a bolt, and the receiving portion 19 b of the fall prevention body 19 is placed below the housing 17. Extend. Next, the car 4 is raised at a low speed, and the rod 14 is inserted into the hole 17 a of the housing 17. When the insertion is completed, the car 4 is stopped, and the nut 18 is screwed onto the rod 14 as shown in FIGS. At this time, even if an operator drops the nut 18, it can be received by the fall prevention body 19.

このように、固定部１５を頂部ビーム１０に取付けられているロッド１４にナット１８により固定することで、かご４上で作業員が作業している時に、かご４が何らかの要因により昇降しようとしても阻止される。   In this way, by fixing the fixing portion 15 to the rod 14 attached to the top beam 10 with the nut 18, when the worker is working on the car 4, the car 4 is going to move up and down due to some factor. Be blocked.

また、作業終了時には、前述と逆の手順、即ち、図４に点線で示すように、固定装置１２の固定部１５を非係合位置とすると共に、落下防止体１９を収納状態とすれば良い。   At the end of the operation, the procedure reverse to that described above, that is, as shown by the dotted line in FIG. .

このような本実施例によれば、固定装置１２として、頂部ビーム１０に、昇降路１の下方に向かって延在するロッド１４を取付けると共に、かご４側に、ロッド１４に係合する係合位置とロッド１４に係合しない非係合位置とに移動可能な固定部１５を備えたことにより、固定装置１２をビーム受け等の部品との兼ね合いで支障をきたすことのない場所に配置することができる。   According to the present embodiment, the fixing device 12 is provided with the rod 14 extending downward from the hoistway 1 to the top beam 10 and engaged with the rod 14 on the car 4 side. By providing the fixing portion 15 that can move between the position and the non-engaging position that does not engage with the rod 14, the fixing device 12 is disposed in a place that does not interfere with the parts such as the beam receiver. Can do.

また、頂部ビーム１０に当たるまで固定装置１２を上昇させることで、更に高い位置までかご４を配置することができる。図示はしないが、頂部ビーム１０まで上昇しなくても、ロッド１４に部材（ナット等も対応可）を挿入することで、所定の位置でかご４を停止することもできる。これらによって、かご４を従来のものより高い位置で固定することができ、従って、保守作業性の向上を図ることができる。   Moreover, the cage | basket | car 4 can be arrange | positioned to a higher position by raising the fixing device 12 until it hits the top beam 10. FIG. Although not shown, the car 4 can be stopped at a predetermined position by inserting a member (a nut or the like is also available) into the rod 14 without rising to the top beam 10. By these, the cage | basket | car 4 can be fixed in a position higher than the conventional thing, Therefore The improvement of maintenance workability | operativity can be aimed at.
