Description

この発明は機械室なしのエレベーター装置に関するものである。 The present invention relates to an elevator apparatus without a machine room.

従来のエレベーター装置では、特開２００７−２９７２０９号公報（特許文献１）に記載されるように、かごとつり合おもりとを懸垂している荷重は、反主索固定台側かごガイドレールと、つり合いおもりガイドレールと、頂部ビーム支持柱の上部に固定された頂部ビームに取付けた頂部綱車と、主索端部に作用しており、この懸垂荷重はかご側ガイドレールと、つり合いおもりガイドレールと、頂部ビーム支持柱で支持する構造としている。さらに、つり合いおもりガイドレールはピットベースの上面に、頂部ビーム支持柱は巻上機固定台を介してピットベースの上面に固定している構造としているので、最下階付近に配置された巻上機綱車に作用する上方向に引き上げられる力を、つり合いおもりガイドレールと、頂部ビーム支持柱で支持する構造としている。かご主索固定台にかかる荷重を除く懸垂荷重と、巻上機綱車の引き上げ荷重と、これらの荷重を支持するガイドレールと頂部ビーム支持柱の位置関係を見た場合、一部の荷重の作用位置は、反主索固定台側かごガイドレールと、主索固定台側つり合いおもりガイドレールとを結んだ直線と頂部ビーム支持柱で構成される三角形の中からはみ出した位置にあり、更に主索固定台側つり合いおもりガイドレールと、頂部ビーム支持柱は昇降路頂部まで立設されず、頂部ビームの下面までとなっている。 In the conventional elevator apparatus, as described in Japanese Patent Application Laid-Open No. 2007-297209 (Patent Document 1), the load that suspends the car and the counterweight is the anti-main rope fixing base side car guide rail, The counterweight guide rail, the top sheave attached to the top beam fixed to the top of the top beam support column, and the main rope end, this suspension load acts on the car side guide rail and the counterweight guide rail And, it is structured to be supported by the top beam support pillar. Furthermore, the counterweight guide rail is fixed to the top surface of the pit base, and the top beam support column is fixed to the top surface of the pit base via a hoisting machine fixing base. The upward pulling force acting on the sheave wheel is supported by a counterweight guide rail and a top beam support column. When looking at the suspension load excluding the load on the car main rope fixing base, the lifting load of the hoisting sheave, and the positional relationship between the guide rail and the top beam support column that support these loads, The working position is at a position that protrudes from the triangle composed of the straight beam connecting the anti-main rope fixing platform side car guide rail and the main rope fixing platform side counterweight guide rail and the top beam support column. The cable fixing base side counterweight guide rail and the top beam support column are not erected up to the top of the hoistway but are extended to the lower surface of the top beam.

特開２００７−２９７２０９号公報JP 2007-297209 A

上記の従来のエレベーター装置は、かご主索固定台にかかる荷重を除く懸垂荷重と、巻上機綱車の引き上げ荷重と、これらの荷重を支持するガイドレールと頂部ビーム支持柱の位置関係を見た場合、一部の荷重の作用位置は、反主索固定台側かごガイドレールと、主索固定台側つり合いおもりガイドレールとを結んだ直線と頂部ビーム支持柱で構成される三角形の中からはみ出した位置にある。このため、はみ出した側にあるガイドレールまたは支持柱には圧縮荷重が、その反対側にあるガイドレールまたは支持柱には引っ張り荷重が作用するため、一部のガイドレールまたは支持柱に荷重が集中する傾向にあり、これらガイドレール及び支持柱の強度を増すために製造コストアップに繋がることが懸念される。その他、主索固定台側つり合いおもりガイドレールと、頂部ビーム支持柱は昇降路頂部まで立設されていないため、建物が鉄骨構造の場合など、ガイドレールおよび頂部ビーム支持柱をレールブラケットを介して建屋に固定できる高さが頂部ビームの下方としなければならず、中間ビーム、もしくは、ファスナープレートなどの追加が必要となるという問題があった。 The above-mentioned conventional elevator apparatus has a suspension load excluding a load applied to the car main rope fixing base, a lifting load of the hoisting sheave, and a positional relationship between the guide rail that supports these loads and the top beam support column. In this case, the position of the part of the load is selected from the triangle composed of the straight beam connecting the anti-main rope fixing platform side car guide rail and the main rope fixing platform side counterweight guide rail and the top beam support column. It is in the position that protrudes. Therefore, compressive load is applied to the guide rail or support column on the protruding side, and tensile load is applied to the guide rail or support column on the opposite side. Therefore, the load is concentrated on some of the guide rails or support columns. In order to increase the strength of the guide rail and the support column, there is a concern that the manufacturing cost may increase. In addition, since the main rope fixed side counterweight guide rail and the top beam support column are not erected up to the top of the hoistway, the guide rail and the top beam support column are connected via the rail bracket when the building is a steel structure. There is a problem that the height that can be fixed to the building has to be below the top beam, and an intermediate beam or a fastener plate is required to be added.

この発明は、上記のような問題を解決するためになされたものであり、比較的簡単な構成により、ガイドレールの強度を大きくすることが無く、コストを低減することができるエレベーター装置を得ることを目的とする。 The present invention has been made to solve the above-described problems, and to obtain an elevator apparatus capable of reducing the cost without increasing the strength of the guide rail with a relatively simple configuration. With the goal.

本発明によるエレベーター装置においては、頂部ビームに取付けられる綱車における荷重作用点と、巻上機の綱車における荷重作用点と、を含む荷重作用点が、これらの荷重を支持するガイドレールと頂部ビーム支持柱で囲まれる仮想多角形内に位置する。 In the elevator apparatus according to the present invention, the load application point including the load application point on the sheave attached to the top beam and the load application point on the sheave of the hoisting machine includes the guide rail and the top part that support these loads. Located in a virtual polygon surrounded by beam support columns.

本発明によれば、ガイドレールと頂部ビーム支持柱に加わる荷重が部分的に集中することが抑制される。このため、ガイドレールと頂部ビーム支持柱の強度またはサイズを大きくすることが防止される。 According to the present invention, partial concentration of the load applied to the guide rail and the top beam support column is suppressed. This prevents an increase in the strength or size of the guide rail and the top beam support column.

以下本発明の実施の形態を、図に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は本発明によるエレベーター装置の一実施形態の概要を示す斜視図、図２は平面図、図３は最上階近傍を示す断面図である。 FIG. 1 is a perspective view showing an outline of an embodiment of an elevator apparatus according to the present invention, FIG. 2 is a plan view, and FIG. 3 is a sectional view showing the vicinity of the top floor.

エレベーターの昇降路１内で構成した機械室なしエレベーターのつり合おもり後ろ配置で、主索５は昇降路頂部に配置したかご側主索固定台６に取付けた主索端部から下方の乗りかご２のかご下綱車７を巻き掛け上方向に返して乗りかご２を懸架して、昇降路頂部に配置したかご側頂部ビーム９に取付けられたかご側頂部綱車８ａ，８ｂに巻き掛けて下方へ返し、最下階床面近傍に配置された巻上機４の綱車に巻き掛けて上方へ返し、昇降路頂部に配置したおもり側頂部ビーム１２に取付けられたおもり側頂部綱車１０に巻き掛けて下方にあるつり合おもり３の綱車で返してつり合おもり３を懸架して、おもり側頂部ビーム１２に取付けてあるおもり側主索固定台１１に主索端部を固定する。 In the elevator hoistway 1, it is located behind the counterweight of the elevator without the machine room, and the main rope 5 is a car below the main rope end attached to the car side main rope fixing base 6 arranged at the top of the hoistway. Wrap 2 car lower sheaves 7 in the upward direction, suspend the car 2 and wrap around the car side top sheaves 8a, 8b attached to the car side top beam 9 arranged on the top of the hoistway. Return to the weight side top sheave 10 attached to the weight side top beam 12 placed on the top of the hoistway and wound around the sheave of the hoisting machine 4 arranged near the floor of the lowermost floor. The main weight end is fixed to the weight-side main rope fixing base 11 attached to the weight-side top beam 12 by suspending the counterweight 3 and suspending the counterweight 3 with the sheave of the counterweight 3 below.

つり合いおもり３は、乗りかご２の背部すなわち、かごドア３０側の反対側とこれに対向する昇降路壁との間の空間に位置する。巻上機４も同空間内に位置し、反主索固定台側おもりガイドレール１７に対してつり合いおもり３の反対側において昇降路内の最下階床レベル付近に固定配置される。巻上機４の電動機部の回転軸には綱車が、減速ギヤを介することなく直接取付けられる。この綱車は、巻上機本体の乗りかご２側に配置される。 The counterweight 3 is located in the space between the back portion of the car 2, that is, the opposite side of the car door 30 side and the hoistway wall facing this. The hoisting machine 4 is also located in the same space, and is fixedly arranged near the lowest floor level in the hoistway on the opposite side of the counterweight 3 with respect to the anti-main rope fixing base side weight guide rail 17. A sheave is directly attached to the rotating shaft of the motor part of the hoisting machine 4 without a reduction gear. This sheave is arranged on the car 2 side of the hoisting machine main body.

巻上機４を駆動すると、乗りかご２は主索固定台６側である主索固定台側かごガイドレール１３と、主索５がかご下綱車７からかご側頂部綱車８ａ，８ｂに伸びる側の反主索固定台側かごガイドレール１４に案内されて昇降し、つり合おもり３はおもり主索固定台１１側である主索固定台側おもりガイドレール１６と、主索５がおもりの綱車から頂部おもり側綱車１０に伸びる側の反主索固定台側おもりガイドレール１７に案内されて、乗りかご２とは反対方向に昇降する。 When the hoisting machine 4 is driven, the car 2 extends to the main rope fixing base side car guide rail 13 which is the main rope fixing base 6 side, and the main rope 5 extends from the car lower sheave 7 to the car side top sheaves 8a and 8b. is guided in a counter main rope fixing stand-side car guide rails 1 4 side by lifting, a main rope fixing stand-side counterweight guide rails 16 Mori 3 is a weight main rope fixing base 11 side counterweight, the main rope 5 weight It is guided by the anti-main rope fixing stand side weight guide rail 17 on the side extending from the sheave to the top weight side sheave 10, and moves up and down in the direction opposite to the car 2.

かご側主索固定台６と、かご側頂部綱車８ａ，８ｂと、おもり側頂部綱車１０と、おもり側主索固定台１１には、乗りかご２とつり合おもり３を懸架している懸垂荷重が作用し、一方、巻上機４の綱車には上方向の引き上げ荷重が作用する。懸垂荷重は昇降路底面に敷いたかご側ピットベース１５の上面に固定したかご側ガイドレール１３，１４と、昇降路底面に敷いたおもり側ピットベース１９の上面に固定した主索固定台側おもりガイドレール１６，反主索固定台側おもりガイドレール１７及び頂部ビーム支持柱１８にて支持している。なお、反主索固定台側かごガイドレール１４と頂部ビーム支持柱１８とを結ぶ仮想直線は、隣接する昇降路壁に平行となる。すなわち、かご側頂部ビーム９は、その長手方向が隣接する昇降路壁と平行となる。また、主索固定台側おもりガイドレール１６と頂部ビーム支持柱１８とを結ぶ仮想直線は、隣接する昇降路壁に平行となる。すなわち、おもり側頂部ビーム１２ａ，１２ｂは、その長手方向が隣接する昇降路壁と平行となる。 A car 2 and a counterweight 3 are suspended from the car-side main rope fixing base 6, the car-side top sheaves 8a and 8b, the weight-side top sheave 10, and the weight-side main rope fixing base 11. A suspension load acts, while an upward pulling load acts on the sheave of the hoisting machine 4. The suspension load is a weight on the main rope fixed base side fixed on the upper surface of the weight side pit base 19 laid on the bottom surface of the hoistway and on the car side guide rails 13 and 14 fixed on the upper surface of the car side pit base 15 laid on the bottom surface of the hoistway. It is supported by a guide rail 16, an anti-main rope fixed base side weight guide rail 17 and a top beam support column 18. In addition, the virtual straight line which connects the anti-main rope fixed base side car guide rail 14 and the top beam support column 18 is parallel to the adjacent hoistway wall. That is, the car side top beam 9 has a longitudinal direction parallel to the adjacent hoistway wall. Moreover, the imaginary straight line which connects the main rope fixed stand side weight guide rail 16 and the top beam support pillar 18 becomes parallel to the adjacent hoistway wall. That is, the weight side top beams 12a and 12b are parallel to the adjacent hoistway walls in the longitudinal direction.

かご側ガイドレール（１３，１４）と、おもり側ガイドレール（１６，１７）と、頂部ビーム支持柱１８はレールブラケット２０ａ〜ｄにて建物のファスナープレート２１ａ〜ｄ、または、建物の梁２２ａ〜ｄなどと強固に固定される（図３参照）。 The car side guide rails (13, 14), the weight side guide rails (16, 17), and the top beam support column 18 are fastened to the fastener plates 21a-d of the building or the beams 22a of the building by rail brackets 20a-d. d and the like (see FIG. 3).

かご側頂部ビーム９は、長尺状部材からなり、その長手方向が乗りかごの奥行方向と平行となるように、両端部がそれぞれ反主索固定台側かごガイドレール１４の頂部と頂部ビーム支持柱１８の頂部に固定される。おもり側頂部ビーム１２ａ，１２ｂは、２本の長尺状部材からなり、それらの長手方向が乗りかご２の背部に位置する昇降路壁面と平行になるように、両端部がそれぞれ主索固定台側おもりガイドレール１６と頂部ビーム支持柱１８の頂部に固定される。かご側頂部ビーム９とおもり側頂部ビーム１２ａ，１２ｂとは、昇降路内の角部で略直角をなす略Ｌ字状になるように配置される。なお、本実施形態では、おもり側頂部ビームを２本の部材により構成しているが、一つの部材により構成しても良い。 The car-side top beam 9 is made of an elongated member, and both ends thereof are respectively supported by the top of the anti-main rope fixing base side car guide rail 14 and the top beam so that the longitudinal direction thereof is parallel to the depth direction of the car. It is fixed to the top of the column 18. The weight side top beams 12a and 12b are composed of two elongated members, and both ends of the main rope fixing base are arranged so that their longitudinal directions are parallel to the hoistway wall surface located on the back of the car 2. Fixed to the tops of the side weight guide rails 16 and the top beam support column 18. The car-side top beam 9 and the weight-side top beams 12a and 12b are arranged so as to be substantially L-shaped at a corner in the hoistway. In the present embodiment, the weight side top beam is constituted by two members, but may be constituted by one member.

図２に示すように、かご側頂部綱車８ａ，８ｂと、おもり側頂部綱車１０と、おもり側主索固定台１１と、これらを取付けているかご側頂部ビーム９と、おもり側頂部ビーム１２ａ，１２ｂが、反主索固定台側かごガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８の平面位置からずれた位置としているため、反主索固定台ガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８は、昇降路頂部まで立設できる。これにより、鉄骨構造などの場合でも、昇降路頂部にある建築の梁，ファスナープレートなどに容易にレールブラケット２０を取付けることが出来るため、頂部ビームの下方に中間ビームなどを追加する必要もなくなる。

As shown in FIG. 2, the car side top sheaves 8a and 8b, the weight side top sheave 10, the weight side main rope fixing base 11 , the car side top beam 9 to which these are attached, and the weight side top beam Since 12a and 12b are the positions shifted from the plane positions of the anti-main rope fixing base side car guide rail 14, the main rope fixing base side weight guide rail 16, and the top beam support column 18, the anti main rope fixing base guide The rail 14, the main rope fixing base side weight guide rail 16 and the top beam support column 18 can be erected up to the top of the hoistway. As a result, even in the case of a steel structure or the like, the rail bracket 20 can be easily attached to an architectural beam, fastener plate, or the like at the top of the hoistway, so there is no need to add an intermediate beam or the like below the top beam.

図２に示すように、かご側頂部綱車８ａ，８ｂはかご側頂部ビーム９の乗りかご側に取付けられる。また、かご側頂部ビーム９は、その乗りかご側において、反主索固定台側かごガイドレール１４及び頂部ビーム支持柱１８の背面に接続される。図２のような昇降路の水平断面で見た場合、主索固定台側おもりガイドレール１６，おもり側主索固定台１１，つり合いおもりの綱車，おもり側頂部綱車１０及び反主索固定台側おもりガイドレール１７，巻上機４の綱車，頂部支持柱１８は、この順で、おもり側頂部ビーム１２ａ，１２ｂである２本の長尺状部材の長手方向に沿って、これら長尺状部材の間に位置する。この内、おもり側頂部綱車１０は、おもり側頂部ビーム１２ａ，１２ｂに固定される。 As shown in FIG. 2, the car side top sheaves 8 a and 8 b are attached to the car side of the car side top beam 9. In addition, the car-side top beam 9 is connected to the back side of the anti-main rope fixing base-side car guide rail 14 and the top beam support column 18 on the car side. When viewed in a horizontal section of the hoistway as shown in FIG. 2, the main rope fixing base side weight guide rail 16, the weight side main rope fixing base 11, the counterweight sheave, the weight side top sheave 10, and the anti main rope fixing The stand side weight guide rail 17, the sheave of the hoisting machine 4, and the top support column 18 are arranged in this order along the longitudinal direction of the two long members that are the weight side top beams 12a and 12b. Located between the scale members. Among these, the weight side top sheave 10 is fixed to the weight side top beams 12a and 12b.

図２のような部品や部材及び機器の配置において、かご側頂部綱車８ａ，８ｂにおける懸垂荷重の荷重作用点は、かご側頂部ビーム９よりも、従って反主索固定台側かごガイドレール１４と頂部ビーム支持柱１８を結ぶ仮想直線よりも、乗りかご側に位置する。また、巻上機４の綱車にかかる引き上げ荷重の荷重作用点と、おもり側頂部綱車１０及びおもり側主索固定台１１における懸垂荷重の荷重作用点は、主索固定台側おもりガイドレール１６と頂部ビーム支持柱１８を結ぶ仮想直線よりも乗りかご側に位置する。 In the arrangement of parts, members and equipment as shown in FIG. 2, the suspension load applied to the car-side top sheaves 8a, 8b is higher than that of the car-side top beam 9, and thus the car guide rail 14 on the anti-main rope fixing base side. And the imaginary straight line connecting the top beam support column 18 and the car side. Further, the load application point of the lifting load applied to the sheave of the hoisting machine 4 and the load application point of the suspension load in the weight side top sheave 10 and the weight side main rope fixing base 11 are the main rope fixing base side weight guide rail. It is located closer to the car than a virtual straight line connecting 16 and the top beam support column 18.

すなわち、かご主索固定台６にかかる荷重を除く懸垂荷重と、巻上機４の綱車の引き上げ荷重と、これらの荷重を支持する反主索固定台ガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８の位置関係を見た場合、全ての荷重の作用位置は、反主索固定台側かごガイドレール１４と、主索固定台側つり合いおもりガイドレール１６とを結んだ仮想直線と頂部ビーム支持柱１８で構成される三角形の中であり、乗りかご２の水平投影を除いた範囲内に入るように構成している。 That is, the suspension load excluding the load applied to the car main rope fixing base 6, the lifting load of the sheave of the hoisting machine 4, the anti-main rope fixing guide rail 14 that supports these loads, and the main rope fixing base side When the positional relationship between the weight guide rail 16 and the top beam support column 18 is viewed, all the load application positions are the anti-main rope fixing base side car guide rail 14 and the main rope fixing base side counterweight guide rail 16. In the triangle formed by the top beam support column 18 and is configured to fall within the range excluding the horizontal projection of the car 2.

ここで、おもり側頂部綱車１０の懸垂荷重を例にとり、図４を用いて説明する。図４の場合、おもり側頂部綱車１０の荷重作用点が反主索固定台側かごガイドレール１４と、主索固定台側つり合いおもりガイドレール１６とを結んだ仮想直線と頂部ビーム支持柱１８で構成される三角形の中に入っているため、それぞれの荷重は下向きに掛かる荷重となるため、荷重が部分的に集中することが抑制される。これにより、一本のガイドレール、もしくは、頂部ビーム支持柱１８に極端に力が集中することを低減させ、ガイドレールと、頂部ビーム支持柱のサイズを大きくする必要がなく、製造コストを抑えることができる。さらに、反主索固定台側かごガイドレール１４の背面と頂部ビーム支持柱１８の背面を結んだ直線と昇降路側壁を平行に配置した場合、かご側頂部ビーム９の構造が簡易な構造とすることができるためコストを安価にすることができる。 Here, the suspension load of the weight side top sheave 10 will be described as an example with reference to FIG. In the case of FIG. 4, the load acting point of the weight-side top sheave 10 is an imaginary straight line connecting the anti-main rope fixing base side car guide rail 14 and the main rope fixing base side counterweight guide rail 16 and the top beam support column 18. Since each load is a load applied downward, the load is suppressed from being partially concentrated. As a result, the concentration of force on one guide rail or the top beam support column 18 is reduced, and it is not necessary to increase the size of the guide rail and the top beam support column, thereby reducing the manufacturing cost. Can do. Further, when the straight line connecting the back surface of the car guide rail 14 on the side opposite to the main rope and the back surface of the top beam support column 18 and the side wall of the hoistway are arranged in parallel, the structure of the car side top beam 9 is simplified. Therefore, the cost can be reduced.

図５は本発明によるエレベーター装置の他の実施形態を示す平面図である。図１と同じ符号は、同じ構成物を示す。図１の実施形態に加えて、昇降路頂部に主索固定台側かごガイドレール１３と主索固定台側おもりガイドレール１６をかご主索固定台側頂部ビーム２３で接続し、そのかご主索固定台側頂部ビーム２３にかご主索固定台６を取付ける構造としている。主索固定台側ガイドレール１３と主索固定台側おもりガイドレール１６とを結ぶ仮想直線は、これに隣接する昇降路壁と平行である。すなわち、かご主索固定台側頂部ビーム２３は、その長手方向が隣接する昇降路壁に平行になるように設けられる。 FIG. 5 is a plan view showing another embodiment of the elevator apparatus according to the present invention. The same reference numerals as those in FIG. 1 denote the same components. In addition to the embodiment of FIG. 1, a main rope fixing base side car guide rail 13 and a main rope fixing base side weight guide rail 16 are connected to the top of the hoistway by a car main rope fixing base side top beam 23, and the car main rope. The car main rope fixing base 6 is attached to the fixing base side top beam 23. An imaginary straight line connecting the main rope fixing base side guide rail 13 and the main rope fixing base side weight guide rail 16 is parallel to the hoistway wall adjacent thereto. That is, the car main rope fixing stand side top beam 23 is provided so that its longitudinal direction is parallel to the adjacent hoistway wall.

かご側頂部綱車８ａ，８ｂと、おもり側頂部綱車１０と、おもり側主索固定台１１と、これらを取付けているかご側頂部ビーム９と、おもり側頂部ビーム１２ａ，１２ｂと、かご主索固定台側頂部ビーム２３が、主索固定台ガイドレール１３と、反主索固定台ガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８の平面位置からずれた位置としている。このため、主索固定台ガイドレール１３と、反主索固定台ガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８は、昇降路頂部まで立設できるので、前述の実施形態同様に、鉄骨構造などの場合でも、昇降路頂部にある建築の梁，ファスナープレートなどに容易にレールブラケットを取付けることができる。これにより、頂部ビームの下方に中間ビームなどを追加する必要がなくなる。 Car side top sheaves 8a, 8b, weight side top sheave 10, weight side main rope fixing base 11, car side top beam 9 to which these are attached, weight side top beams 12a, 12b, The cable fixing platform side top beam 23 is shifted from the plane position of the main cable fixing platform guide rail 13, the anti-main cable fixing platform guide rail 14, the main cable fixing platform side weight guide rail 16, and the top beam support column 18. The position. Therefore, the main rope fixing base guide rail 13, the anti-main rope fixing base guide rail 14, the main rope fixing base side weight guide rail 16 and the top beam support column 18 can be erected up to the top of the hoistway. Similarly to the embodiment, even in the case of a steel structure or the like, the rail bracket can be easily attached to an architectural beam, a fastener plate or the like at the top of the hoistway. This eliminates the need to add an intermediate beam or the like below the top beam.

また、全ての懸垂荷重と、巻上機４の綱車の引き上げ荷重と、これらの荷重を支持する主索固定台ガイドレール１３と、反主索固定台ガイドレール１４と、主索固定台側おもりガイドレール１６と、頂部ビーム支持柱１８の位置関係を見た場合、全ての荷重の作用位置は、両方のかごガイドレール１３，１４と、主索固定台側つり合いおもりガイドレール１６と頂部ビーム支持柱１８を仮想直線で結ぶ仮想四角形の中に入るように構成しているので、ガイドレールもしくは頂部ビーム支持柱に部分的に荷重が集中することを低減させ、ガイドレールと、頂部ビーム支持柱のサイズを大きくする必要がなく、製造コストを抑えることができる。 Moreover, all suspension loads, the lifting load of the sheave of the hoist 4, the main rope fixing guide rail 13 that supports these loads, the anti-main rope fixing guide rail 14, and the main rope fixing stand side When the positional relationship between the weight guide rail 16 and the top beam support column 18 is viewed, all the loads are applied at the positions of both the car guide rails 13 and 14, the main rope fixing side counterweight guide rail 16 and the top beam. Since the support column 18 is configured to fall within a virtual quadrilateral connecting the virtual straight lines, it is possible to reduce the partial concentration of the load on the guide rail or the top beam support column, and the guide rail and the top beam support column. There is no need to increase the size of the device, and the manufacturing cost can be reduced.

さらに、主索固定台側かごガイドレール１４の背面と主索固定台側かおもりレール１６背面を結んだ直線と昇降路側壁を平行に配置した場合、かご側頂部ビーム９の構造が簡易な構造とすることができるためコストを安価にすることができる。 Further, when the straight line connecting the back surface of the main rope fixing base side car guide rail 14 and the back surface of the main rope fixing base side weight rail 16 and the side wall of the hoistway are arranged in parallel, the structure of the car side top beam 9 is simple. Therefore, the cost can be reduced.
