　ところで、エレベータ装置の省スペース化は、機器類の配置や、各機器類自体を小型化すること等により実現するものである。しかし、省スペース化を実現する際に、昇降路機器の配置の関係から、釣合いおもりのウェートの形状を異型にすることが求められることがある。このようにウェートの形状を異型にすると、釣合いおもりの重心が偏芯するため、ガイド装置に比較的大きな反力が作用し、ガイド装置の寿命を早める可能性がある。　
　しかしながら、特許文献１に記載のものを含めて、従来、釣合いおもりについては、省スペース化を図ることを目的として構成されており、釣合いおもりの重心の偏芯については特に考慮されていない。 By the way, the space saving of the elevator apparatus is realized by arranging the devices or reducing the size of each device itself. However, when realizing space saving, it may be required to make the weight of the counterweight different from the shape of the hoistway device. In this way, if the weight has a different shape, the center of gravity of the counterweight is decentered, so that a relatively large reaction force acts on the guide device, which may prolong the life of the guide device.
However, conventionally, counterweights including those described in Patent Document 1 are configured for the purpose of space saving, and the eccentricity of the center of gravity of the counterweight is not particularly taken into consideration.

A counterweight frame composed of an upper plate, a plurality of weights loaded on the counterweight frame, a pulley attached to the upper plate and around which a main rope is wound, and opposed surfaces of the pair of vertical frames And a plurality of guide devices attached to the upper and lower ends of each of the pair of vertical frames and slidingly contacting the guide rail to guide the lifting and lowering of the counterweight, When the upper ends of the pair of vertical frames are located above the upper surface of the upper plate, and the attachment device is attached to the upper ends of the pair of vertical frames or the upper portions of the pair of vertical frames, the attachment device The top of the balance is To lie within the forest height limit, characterized in that setting the length in the height direction of the pair of vertical frames.
　本発明によれば、釣合いおもりのウェートの形状を異型にした場合でも、ガイド装置への反力の低減を図ることができる。

　釣合いおもり枠２は、間隔をおいて対向配置された（図１の左右両側に配置された）一対のたて枠２ａ，２ｂ、たて枠２ａ，２ｂの下端部を連結する下側板２ｃ、およびたて枠２ａ，２ｂの上端部を連結する上側板２ｄから構成されている。 The counterweight frame 2 has a pair of vertical frames 2a and 2b (disposed on both the left and right sides in FIG. 1) opposed to each other with a space therebetween, and a lower plate 2c that connects the lower ends of the vertical frames 2a and 2b. And it is comprised from the upper side board 2d which connects the upper end part of the vertical frames 2a and 2b.
　たて枠２ａ，２ｂは、図３に示すように、それぞれコ字状の断面形状を有しており、開口側が互いに向き合うように配置され、反開口側がそれぞれガイドレール７ａ，７ｂに対向するようになっている。 As shown in FIG. 3, each of the vertical frames 2a and 2b has a U-shaped cross-sectional shape, is arranged so that the opening sides face each other, and the opposite opening side faces the guide rails 7a and 7b, respectively. It has become.
　下側板２ｃは、その両端がボルトによりたて枠２ａ，２ｂの下部に固定され、複数積載されるウェート３の荷重を受けるようになっている。また、最上位置に配置されるウェート３がウェート押さえ１０ａ，１０ｂにより下方向に押圧されることで、ウェート３全体として下側板２ｃに押し付けられ、ガタつきが生じないようになっている。また、下側板２ｃの下部には、昇降路の底部に設置されている緩衝装置（図示省略）によって受け止められる受け部１２が取り付けられている。 The lower plate 2c is fixed to the lower part of the vertical frames 2a and 2b with bolts at both ends so as to receive the load of a plurality of weights 3 loaded thereon. Further, when the weight 3 arranged at the uppermost position is pressed downward by the weight presses 10a and 10b, the weight 3 as a whole is pressed against the lower side plate 2c, so that there is no backlash. Moreover, the receiving part 12 received by the buffering device (illustration omitted) installed in the bottom part of the hoistway is attached to the lower part of the lower side board 2c.
　上側板２ｄは、その両端がボルトによりたて枠２ａ，２ｂの上部に固定され、その上面には、ブラケット８を介しておもり上プーリ４００が回転可能に取り付けられている。 Both ends of the upper plate 2d are fixed to the upper portions of the vertical frames 2a and 2b by bolts, and a weight upper pulley 400 is rotatably attached to the upper surface via a bracket 8.
　おもり上プーリ４００には主ロープ（図示省略）が巻き掛けられ、釣合いおもり１００は、おもり上プーリ４００を介して主ロープにより懸架される。本実施形態では、おもり上プーリ４００は上側板２ｄ上に載置されている。すなわち、おもり上プーリ４００の下端は最上位置に配置されるウェート３の上面よりも上方に位置している。おもり上プーリ４００は上側板２ｄ上に載置されているので、おもり上プーリ４００のメンテナンスが容易となる。 A main rope (not shown) is wound around the weight upper pulley 400, and the counterweight 100 is suspended by the main rope via the weight upper pulley 400. In the present embodiment, the weight upper pulley 400 is placed on the upper plate 2d. That is, the lower end of the weight upper pulley 400 is located above the upper surface of the weight 3 disposed at the uppermost position. Since the weight upper pulley 400 is placed on the upper plate 2d, the maintenance of the weight upper pulley 400 is facilitated.
　ガイド装置５ａ，５ｂ，５ｃ，５ｄは、釣合いおもり枠２の四隅付近に配置されている。すなわち、ガイド装置５ａがたて枠２ａの上端部、ガイド装置５ｂがたて枠２ａの下端部、ガイド装置５ｃがたて枠２ｂの上端部、ガイド装置５ｄがたて枠２ｂの下端部のそれぞれにおける反開口側に取り付けられ、ガイド装置５ａ，５ｂはガイドレール７ａに、ガイド装置５ｃ，５ｄはガイドレール７ｂにそれぞれ摺動接触して釣合いおもり１の昇降を案内する。 Guide devices 5 a, 5 b, 5 c and 5 d are arranged near the four corners of the counterweight frame 2. That is, the guide device 5a is the upper end of the vertical frame 2a, the guide device 5b is the lower end of the vertical frame 2a, the guide device 5c is the upper end of the vertical frame 2b, and the guide device 5d is the lower end of the vertical frame 2b. The guide devices 5a and 5b are attached to the guide rail 7a, and the guide devices 5c and 5d are in sliding contact with the guide rail 7b, respectively, to guide the lifting and lowering of the counterweight 1.
　給油装置６ａ，６ｂは、たて枠２ａ，２ｂの上部、すなわち、ガイド装置５ａ，５ｃに近接する位置に取り付けられている。本実施形態では、給油装置６ａ，６ｂは、たて枠２ａ，２ｂの上部にそれぞれ取り付けられた逆L字形の取り付け部材１１ａ，１１ｂに取り付けられている。給油装置６ａ，６ｂのそれぞれは、潤滑油を貯蔵するタンクを有しており、それらのタンクから潤滑油をゆっくり供給する構造を有する。そして、給油装置６ａ，６ｂは、それぞれガイドレール７ａ，７ｂに潤滑油を塗布し、ガイド装置５ａ，５ｂ，５ｃ，５ｄとガイドレール７ａ，７ｂとの間に潤滑油を供給する。 The oil supply devices 6a and 6b are attached to the upper portions of the vertical frames 2a and 2b, that is, at positions close to the guide devices 5a and 5c. In this embodiment, the oil supply devices 6a and 6b are attached to inverted L- shaped attachment members 11a and 11b attached to the upper portions of the vertical frames 2a and 2b, respectively. Each of the oil supply devices 6a and 6b has a tank for storing the lubricating oil, and has a structure for slowly supplying the lubricating oil from these tanks. The oil supply devices 6a and 6b apply lubricant to the guide rails 7a and 7b, respectively, and supply the lubricant between the guide devices 5a, 5b, 5c, and 5d and the guide rails 7a and 7b.
　下側板２ｃに複数積載されるウェート３は、本実施形態では、図３に示すように、その形状が異型となっている。すなわち、上面（水平面）から見たウェート形状が異型となっている。ここでウェート形状が異型とは、本実施形態では、非対称形状を意味する。また、言い換えれば、ウェート形状が異型とは、上面から見たウェートの重心位置が、上面から見たたて枠２ａ，２ｂで形成される領域の重心位置からずれていることであるとも言える。 In the present embodiment, the weights 3 stacked on the lower plate 2c have different shapes as shown in FIG. That is, the weight shape seen from the upper surface (horizontal plane) is atypical. Here, the irregular shape of the weight means an asymmetric shape in the present embodiment. In other words, when the weight shape is different, it can be said that the center of gravity position of the weight viewed from the top surface is shifted from the center of gravity position of the region formed by the vertical frames 2a and 2b when viewed from the top surface.
　本実施形態では、ウェート３は、釣合いおもり枠のたて枠のスリム化や効率的な空間利用を図るために、その両端が、コ字状の断面形状を有するたて枠２ａ，２ｂに嵌合可能なように幅狭となっているとともに、その中央部は、たて枠の幅寸法より幅広となっている。エレベータ装置の省スペース化を図っていくと、このウェートを異型にすることが求められる。例えば、エレベータ装置の省スペース化を図っていくと、ガイドレール７ａ，７ｂを壁側（図３の上側）に寄って設置せざるを得ない。このため、ウェート３は、両端を中央部に対してずれるように配置せざるを得ない。したがって、ウェート３は、幅広の中央部が乗りかご側（図３の下側）に寄って位置するように形成されることになり、中央部が幅方向から見て非対称（図３の図面上、上下非対称）の形状となっている。言い換えれば、ウェート３の中心線（図３の二点鎖線。線上に重心が位置。）が、たて枠２ａ，２ｂで形成される領域の中心線（図３の一点鎖線。ガイドレール７ａ，７ｂを結ぶ線と一致し線上に重心が位置。）からずれることになる。 In this embodiment, the weight 3 is fitted to the vertical frames 2a and 2b having U-shaped cross-sections at both ends in order to reduce the vertical frame of the counterweight frame and to efficiently use the space. The width is narrow so that they can be combined, and the central portion is wider than the width of the vertical frame. In order to save space in the elevator apparatus, it is required to make this weight different. For example, if the space of the elevator apparatus is to be saved, the guide rails 7a and 7b have to be installed close to the wall side (upper side in FIG. 3). For this reason, the weight 3 has to be arranged so that both ends are deviated from the central portion. Therefore, the weight 3 is formed so that the wide central portion is located closer to the car side (the lower side in FIG. 3), and the central portion is asymmetrical (on the drawing in FIG. 3). , The shape is asymmetric). In other words, the center line of the weight 3 (the two-dot chain line in FIG. 3; the center of gravity is located on the line) is the center line of the area formed by the vertical frames 2a and 2b (the one-dot chain line in FIG. 3; the guide rail 7a, 7b coincides with the line connecting 7b and the center of gravity is located on the line.
　また、昇降路機器９の配置の関係（ロープエンドの位置との関係や調速機上置きの場合の調速機の位置との関係など）で、図３に示すように、上面からみたウェート３の一部を切欠いてウェート３を形成する場合がある。この場合にもウェート３が長さ方向から見て非対称形状（図３の図面上、左右非対称の形状）になる。図３に示すように、上下，左右に非対称にウェート３が形成されると、釣合いおもりの重心の偏芯による影響が大きくなり、ガイド装置により大きな反力が作用する可能性がある。 Further, as shown in FIG. 3, the weight of the hoistway device 9 as viewed from the top surface in relation to the arrangement of the hoistway device 9 (relationship with the position of the rope end, relation with the position of the speed governor when placed on the speed governor). There is a case where the weight 3 is formed by cutting out a part of 3. Also in this case, the weight 3 has an asymmetrical shape (asymmetrical shape in the drawing of FIG. 3) when viewed from the length direction. As shown in FIG. 3, when the weight 3 is formed asymmetrically in the vertical and horizontal directions, the influence of the eccentricity of the center of gravity of the counterweight increases, and a large reaction force may act on the guide device.
　そして、本実施形態のエレベータ装置では、異型のウェート３を用いたものにあって、ガイド装置５ａ～５ｄへの反力の低減を図るために工夫が施されている。具体的には、たて枠２ａ，２ｂを、釣合いおもり高さ制限内で延長寸法Ｈ１、延長し、上端部側のガイド装置５ａ，５ｃと下端部側のガイド装置５ｂ，５ｄとの間隔寸法Ｈ２を大きく設定している。釣合いおもり高さ制限内とは、エレベータ装置の仕様としてあらかじめ定められる釣合いおもり１００のオーバーヘッド寸法以内ということである。 The elevator apparatus according to the present embodiment uses an unusual weight 3 and is devised to reduce the reaction force to the guide apparatuses 5a to 5d. Specifically, the vertical frames 2a and 2b are extended by an extension dimension H1 within the limit of the counterweight, and the distance between the guide devices 5a and 5c on the upper end side and the guide devices 5b and 5d on the lower end side is extended. H2 is set large. Within the counterweight height limit is within the overhead dimensions of the counterweight 100 that is predetermined as the specifications of the elevator apparatus.
　以下に、たて枠を釣合いおもり高さ制限内で延長寸法Ｈ１延長することの意義を説明する。 Hereinafter, the significance of extending the vertical dimension H1 within the limits of the counterweight height will be described.
　釣合いおもり枠２は、工場からエレベータ装置の据え付け場所へ組立体として搬送されるので、たて枠２ａ，２ｂの上端が上側板２ｄの上面から突出しないように、本来的にはたて枠２ａ，２ｂの高さを上側板２ｄの上面の高さと略同じにするのが望ましい。本実施形態では、異型のウェート３に起因するガイド装置５ａ～５ｄへの反力を低減するという新たな着眼点から、上端部側のガイド装置５ａ，５ｃと下端部側のガイド装置５ｂ，５ｄとの間隔寸法Ｈ２を大きく設定するため、たて枠２ａ，２ｂを上方へ敢えて延長するものである。 Since the counterweight frame 2 is transported as an assembly from the factory to the place where the elevator apparatus is installed, the vertical frame 2a is originally provided so that the upper ends of the vertical frames 2a and 2b do not protrude from the upper surface of the upper plate 2d. , 2b is preferably substantially the same as the height of the upper surface of the upper plate 2d. In the present embodiment, the guide devices 5a and 5c on the upper end side and the guide devices 5b and 5d on the lower end side from the new point of view that the reaction force to the guide devices 5a to 5d caused by the irregular weight 3 is reduced. The vertical frames 2a and 2b are intentionally extended upward in order to set a large distance dimension H2.
　本実施形態では、上側板２ｄの上面におもり上プーリ４００を設置している。このようなエレベータ装置では、エレベータ装置の仕様としてあらかじめ定められる釣合いおもり１００のオーバーヘッド寸法H０は、たて枠２ａ，２ｂ下端から、おもり上プーリ４００を固定するブラケット８の上端までの高さ寸法となる。たて枠の上端（たて枠の上部に給油装置などの付属装置が取り付けられる場合には付属装置の上端）の位置がオーバーヘッド寸法H０の範囲内に納まる限りにおいて、たて枠２ａ，２ｂを上側板２ｄの上面を超えて上方に延長することが許容される。本実施形態では、たて枠２ａ，２ｂの上部に給油装置６ａ，６ｂが取り付けられているので、たて枠２ａ，２ｂ下端から給油装置６ａ，６ｂの上端までの高さ寸法が、オーヘッド寸法を超えない範囲で、たて枠２ａ，２ｂを上側板２ｄの上面を超えて上方に延長するようにしている。言い換えれば、本実施形態では、たて方向の既存スペースを有効利用して、たて枠２ａ，２ｂを延長したものである。 In this embodiment, the upper pulley 400 is installed on the upper surface of the upper plate 2d. In such an elevator apparatus, the overhead dimension H0 of the counterweight 100, which is predetermined as the specifications of the elevator apparatus, is the height dimension from the lower end of the vertical frames 2a, 2b to the upper end of the bracket 8 that fixes the weight upper pulley 400. Become. As long as the position of the upper end of the vertical frame (the upper end of the auxiliary device when an auxiliary device such as a fueling device is attached to the upper part of the vertical frame) is within the range of the overhead dimension H0, the vertical frames 2a and 2b It is allowed to extend upward beyond the upper surface of the upper plate 2d. In this embodiment, since the oil supply devices 6a and 6b are attached to the upper portions of the vertical frames 2a and 2b, the height dimension from the lower end of the vertical frames 2a and 2b to the upper end of the oil supply devices 6a and 6b is the overhead dimension. The vertical frames 2a and 2b are extended upward beyond the upper surface of the upper plate 2d within a range not exceeding. In other words, in this embodiment, the vertical frames 2a and 2b are extended by effectively using the existing space in the vertical direction.
　ガイド装置が受ける反力は、ウェート３の重心の偏心度合に応じて異なる。重心の偏心度合が大きければ、たて枠２ａ，２ｂを最大限延長するのが望ましい。すなわち、図１に示すように、たて枠２ａ，２ｂの上部に取り付けられる給油装置６ａ，６ｂの上端が、おもり上プーリ４００を固定するブラケット８の上端と略同一レベル（釣合いおもり高さ制限付近）となるように、たて枠２ａ，２ｂを上方に延長寸法H１だけ延長する（ただし、給油装置６ａ，６ｂの上端が釣合いおもり高さ制限、すなわち、オーバーヘッド寸法以内）。ここで、釣合いおもり高さ制限付近とは、本実施形態では、給油装置６ａ，６ｂの上端がブラケット８の上端と同一レベルになるときを１００％延長とした場合、少なくとも９０％延長した場合を意味する。また、ガイド装置が受ける反力の低減効果を十分に得るには、たて枠２ａ，２ｂは、給油装置６ａ，６ｂの上端がブラケット８の上端と同一レベルになるときを１００％延長とした場合、５０％程度延長するのが望ましい。 The reaction force received by the guide device varies depending on the degree of eccentricity of the center of gravity of the weight 3. If the degree of eccentricity of the center of gravity is large, it is desirable to extend the vertical frames 2a and 2b as much as possible. That is, as shown in FIG. 1, the upper ends of the oil supply devices 6a and 6b attached to the upper portions of the vertical frames 2a and 2b are substantially at the same level as the upper end of the bracket 8 that fixes the weight upper pulley 400 (the counterweight height limit). The vertical frames 2a and 2b are extended upward by an extension dimension H1 so that the upper ends of the oil supply devices 6a and 6b are within the upper limit of the counterweight, that is, within the overhead dimension. Here, in the present embodiment, the vicinity of the counterweight height limit is a case where the upper end of the oil supply devices 6a, 6b is at the same level as the upper end of the bracket 8 and is extended by at least 90%. means. Further, in order to sufficiently obtain the effect of reducing the reaction force received by the guide device, the vertical frames 2a and 2b are extended by 100% when the upper ends of the oil supply devices 6a and 6b are at the same level as the upper end of the bracket 8. In this case, it is desirable to extend it by about 50%.
　本実施形態にあっては、昇降路機器９などの配置の関係から、釣合いおもり１００のウェート３の形状が異型となっている。このようなウェート３を積載した釣合いおもり１００を実際に昇降させると、釣合いおもり１００の重心が偏芯していることから、釣合いおもり１００の四隅付近に配置されるガイド装置５ａ～５ｃには比較的大きな反力が作用する。しかしながら、本実施形態のたて枠２ａ，２ｂは、上側板２ｄから上方に向かって延長寸法Ｈ１、延長されており、上端部側のガイド装置５ａ，５ｃと下端部側のガイド装置５ｂ，５ｄとの間隔寸法Ｈ２が大きく設定されている。このことから、ガイド装置５ａ～５ｃに作用する反力を低減することができ、これによって、ガイド装置５ａ～５ｄの延命化を図ることができる。 In this embodiment, the shape of the weight 3 of the counterweight 100 is atypical because of the arrangement of the hoistway device 9 and the like. When the counterweight 100 loaded with the weight 3 is actually moved up and down, the center of gravity of the counterweight 100 is decentered. Therefore, it is compared with the guide devices 5a to 5c arranged near the four corners of the counterweight 100. Large reaction force acts. However, the vertical frames 2a and 2b of the present embodiment are extended upward from the upper plate 2d by the extension dimension H1, and the guide devices 5a and 5c on the upper end side and the guide devices 5b and 5d on the lower end side are extended. Is set large. Accordingly, the reaction force acting on the guide devices 5a to 5c can be reduced, and thereby the life of the guide devices 5a to 5d can be extended.
　また、本実施形態では、たて枠２ａ，２ｂを、釣合いおもり高さ制限内で延長するものであるが、たて方向の既存スペースを有効利用してたて枠２ａ，２ｂを延長したものであり、釣合いおもり１００の全高さ寸法の変更を要することがない。このことから、他の機器や設置条件へ影響を及ぼすことなく、ガイド装置５ａ～５ｄへの反力の低減を図ることができる。 In this embodiment, the vertical frames 2a and 2b are extended within the counterweight height limit, but the vertical frames 2a and 2b are extended by effectively using the existing space in the vertical direction. It is not necessary to change the overall height of the counterweight 100. Thus, the reaction force to the guide devices 5a to 5d can be reduced without affecting other devices and installation conditions.
