Description

エレベータのレール継目板装置及びガイドレール装置Elevator rail joint plate device and guide rail device
　この発明は、ガイドレールを構成する複数のレール部材のうち、上下に隣接するレール部材を接続するエレベータのレール継目板装置、及び上下のレール部材とレール継目板装置とを有するガイドレール装置に関するものである。 The present invention relates to an elevator rail joint plate device for connecting rail members adjacent to each other among a plurality of rail members constituting a guide rail, and a guide rail device having upper and lower rail members and a rail joint plate device. It is.
　従来のエレベータでは、かご又は釣合おもりの昇降を案内する複数のガイドレールが昇降路内に設置されている。各ガイドレールは、複数のレール部材を上下方向に継ぎ合わせて構成されている。また、上下に隣接するレール部材は、継目板を介して接続されている。 In a conventional elevator, a plurality of guide rails for guiding the raising or lowering of a car or a counterweight are installed in the hoistway. Each guide rail is configured by joining a plurality of rail members in the vertical direction. Moreover, the rail member adjacent on the upper and lower sides is connected through the joint plate.
　レール部材としては、一般的に中実の鋼製レールが用いられているが、板材をロールフォーミングによって成形した鋼板レールも提案されており、鋼製レールよりも安価でかつ軽量となる利点がある。 As the rail member, a solid steel rail is generally used, but a steel plate rail formed by roll forming of a plate material has also been proposed, which has the advantage of being cheaper and lighter than the steel rail. .
　また、レール部材として鋼板レールを用いる場合、上下のレール部材の水平方向位置を調整するため、上下のレール部材の継目部分の内側に、一回り小さい鋼製レール又は鋼板レールが継目板として取り付けられる。しかし、板材を折り曲げ加工して製作される鋼板レールは、切削加工により製作される鋼製レールに比べて精度が落ちるため、レール部材と継目板との間に隙間が生じ、調整の手間が増えたり、上下のレール部材間で段差が生じたりする。 Further, when using steel plate rails as the rail members, in order to adjust the horizontal position of the upper and lower rail members, a slightly smaller steel rail or steel plate rail is attached as a joint plate inside the joint portion of the upper and lower rail members. . However, steel sheet rails manufactured by bending plate materials are less accurate than steel rails manufactured by cutting, so a gap is created between the rail member and the joint plate, increasing the adjustment effort. Or a difference in level occurs between the upper and lower rail members.
　これに対して、従来のエレベータのガイドレールでは、鋼板レールのフランジ端の形状を変更したり、継目板にボルトを追加して鋼板レールのフランジ面の外側から締め付けたりすることで、水平方向の位置を微調整することを実現している（例えば、特許文献１参照）。 On the other hand, in the conventional guide rails for elevators, the shape of the flange end of the steel plate rail can be changed, or bolts can be added to the joint plate and tightened from the outside of the flange surface of the steel plate rail. Fine adjustment of the position is realized (for example, see Patent Document 1).

　以下、この発明を実施するための形態について、図面を参照して説明する。
　実施の形態１．
　図１はこの発明の実施の形態１によるエレベータを示す概略の構成図である。図において、昇降路１の上部には、巻上機２が設置されている。巻上機２は、駆動シーブ３と、駆動シーブ３を回転させる巻上機モータと、駆動シーブ３の回転を制動する巻上機ブレーキとを有している。駆動シーブ３には、懸架手段４が巻き掛けられている。懸架手段４としては、複数本のロープ又は複数本のベルトが用いられている。 Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
Embodiment 1 FIG.
1 is a schematic configuration diagram showing an elevator according to Embodiment 1 of the present invention. In the figure, a hoisting machine 2 is installed at the upper part of the hoistway 1. The hoisting machine 2 includes a drive sheave 3, a hoisting machine motor that rotates the driving sheave 3, and a hoisting machine brake that brakes the rotation of the driving sheave 3. A suspension means 4 is wound around the drive sheave 3. As the suspension means 4, a plurality of ropes or a plurality of belts are used.
　懸架手段４の第１の端部には、昇降体であるかご５が接続されている。懸架手段４の第２の端部には、他の昇降体である釣合おもり６が接続されている。かご５及び釣合おもり６は、懸架手段４によって昇降路１内に吊り下げられており、巻上機２の駆動力によって昇降される。 A car 5, which is a lifting body, is connected to the first end of the suspension means 4. A counterweight 6, which is another lifting body, is connected to the second end of the suspension means 4. The car 5 and the counterweight 6 are suspended in the hoistway 1 by the suspension means 4 and are raised and lowered by the driving force of the hoisting machine 2.
　昇降路１内には、かご５の昇降を案内する一対のかごガイドレール７と、釣合おもり６の昇降を案内する一対の釣合おもりガイドレール８とが設置されている。かごガイドレール７は、かご５の幅方向両側に互いに対向して配置されている。即ち、かご５は、かごガイドレール７間に配置されている。 In the hoistway 1, a pair of car guide rails 7 that guide the raising and lowering of the car 5 and a pair of counterweight guide rails 8 that guide the raising and lowering of the counterweight 6 are installed. The car guide rails 7 are arranged opposite to each other on both sides in the width direction of the car 5. That is, the car 5 is disposed between the car guide rails 7.
　釣合おもりガイドレール８は、釣合おもり６の幅方向両側に互いに対向して配置されている。即ち、釣合おもり６は、釣合おもりガイドレール８間に配置されている。 The counterweight guide rails 8 are arranged opposite to each other on both sides in the width direction of the counterweight 6. That is, the counterweight 6 is disposed between the counterweight guide rails 8.
　各かごガイドレール７は、複数のかごレール部材９を上下方向に継ぎ合わせて構成されている。また、上下に隣接するかごレール部材９は、かごレール継目板装置１０を介して接続されている。 Each car guide rail 7 is constituted by joining a plurality of car rail members 9 in the vertical direction. Further, the car rail members 9 adjacent to each other in the vertical direction are connected via a car rail joint plate device 10.
　かご５には、かごガイドレール７に係合してかご５を非常停止させる非常止め装置が搭載されている。このため、かごレール部材９としては、非常止め装置の作動時にレール断面が潰れないように、図２に示すような水平断面を持つ鋼製レールが使用されている。 The car 5 is equipped with an emergency stop device that engages with the car guide rail 7 to stop the car 5 in an emergency. Therefore, as the car rail member 9, a steel rail having a horizontal cross section as shown in FIG. 2 is used so that the rail cross section is not crushed when the safety device is operated.
　各釣合おもりガイドレール８は、複数の釣合おもりレール部材１１を上下方向に継ぎ合わせて構成されている。また、上下に隣接する釣合おもりレール部材１１は、釣合おもりレール継目板装置１２を介して接続されている。 Each counterweight guide rail 8 is configured by joining a plurality of counterweight rail members 11 in the vertical direction. Further, the counterweight rail members 11 adjacent to each other in the vertical direction are connected via a counterweight rail joint plate device 12.
　また、この例では、釣合おもり６に非常止め装置が搭載されていないため、釣合おもりレール部材１１として、ロールフォーミングによって成形され、図３に示すような水平断面を持つ鋼板レールが使用されている。また、釣合おもりレール部材１１は、断面Ｕ字形のレールブレード部１１ａと、レールブレード部１１ａの基端部から外側へ直角に突出した一対のレールフランジ部１１ｂとを有している。 Moreover, in this example, since the emergency stop device is not mounted on the counterweight 6, a steel plate rail formed by roll forming and having a horizontal cross section as shown in FIG. 3 is used as the counterweight rail member 11. ing. Further, the counterweight rail member 11 has a rail blade portion 11a having a U-shaped cross section and a pair of rail flange portions 11b projecting outward from the base end portion of the rail blade portion 11a at a right angle.
　なお、図１のＺ軸は上下方向、Ｘ軸はかご５の前後方向（奥行き方向）、Ｙ軸はかご５の幅方向（左右方向）を示しており、以下の図でも同様である。また、Ｘ軸とＹ軸とを含む平面を水平面とする。 In FIG. 1, the Z-axis indicates the vertical direction, the X-axis indicates the front-rear direction (depth direction) of the car 5, and the Y-axis indicates the width direction (left-right direction) of the car 5. The same applies to the following figures. A plane including the X axis and the Y axis is a horizontal plane.
　また、図１では、かご５及び釣合おもり６を横に展開して示しているが、実際には、釣合おもり６は、かご５の後方に配置されている。 Further, in FIG. 1, the car 5 and the counterweight 6 are shown to be expanded horizontally, but in reality, the counterweight 6 is disposed behind the car 5.
　図４は図１の釣合おもりレール継目板装置１２を示す正面図、図５は図４のＶ－Ｖ線に沿う断面図である。釣合おもりレール継目板装置１２は、平板を折り曲げ加工してなる継目板１３と、継目板１３を釣合おもりレール部材１１に対して固定するための複数の締付具１４とを有している。 4 is a front view showing the counterweight rail joint plate device 12 of FIG. 1, and FIG. 5 is a sectional view taken along the line VV of FIG. The counterweight rail joint plate device 12 includes a joint plate 13 formed by bending a flat plate, and a plurality of fasteners 14 for fixing the joint plate 13 to the counterweight rail member 11. Yes.
　継目板１３は、平板部１３ａと、平板部１３ａの幅方向両端部に設けられているガイド部としての一対の折り返し傾斜部１３ｂとを有している。平板部１３ａは、上下の釣合おもりレール部材１１に跨って、レールフランジ部１１ｂの背面に当接されている。 The joint plate 13 has a flat plate portion 13a and a pair of folded inclined portions 13b as guide portions provided at both ends in the width direction of the flat plate portion 13a. The flat plate portion 13 a is in contact with the back surface of the rail flange portion 11 b across the upper and lower counterweight rail members 11.
　折り返し傾斜部１３ｂは、平板部１３ａに対して鋭角をなすように折り返されており、地面と平行な断面（水平断面）において、レールフランジ部１１ｂに対して傾斜している。即ち、平板部１３ａと折り返し傾斜部１３ｂとがつくる角度θは、鋭角になっている。レールフランジ部１１ｂの幅方向のレールブレード部１１ａとは反対側の端部は、それぞれ平板部１３ａと折り返し傾斜部１３ｂとの間に挟まれている。 The folded inclined portion 13b is folded so as to form an acute angle with respect to the flat plate portion 13a, and is inclined with respect to the rail flange portion 11b in a cross section (horizontal cross section) parallel to the ground. That is, the angle θ formed by the flat plate portion 13a and the folded inclined portion 13b is an acute angle. The end of the rail flange portion 11b opposite to the rail blade portion 11a in the width direction is sandwiched between the flat plate portion 13a and the folded inclined portion 13b.
　各締付具１４としては、ボルト及びナットの組み合わせが用いられている。ナットは、平板部１３ａの背面に配置されている。ボルトは、折り返し傾斜部１３ｂ、レールフランジ部１１ｂ及び平板部１３ａを貫通してナットに螺着されている。折り返し傾斜部１３ｂ、レールフランジ部１１ｂ及び平板部１３ａには、ボルトを通す貫通孔が予め設けられている。これらの貫通孔の径とボルトの径との間には、ある程度の余裕（遊び）が設けられている。 Each bolt 14 is a combination of bolts and nuts. The nut is disposed on the back surface of the flat plate portion 13a. The bolt passes through the folded inclined portion 13b, the rail flange portion 11b, and the flat plate portion 13a and is screwed to the nut. A through hole through which a bolt is passed is provided in advance in the folded inclined portion 13b, the rail flange portion 11b, and the flat plate portion 13a. A certain amount of allowance (play) is provided between the diameters of the through holes and the bolts.
　継目板１３は、締付具１４を締め付けたときに折り返し傾斜部１３ｂの中間部がレールフランジ部１１ｂに沿って容易に変形しないように十分な剛性を有している。折り返し傾斜部１３ｂは、締付具１４の締付時に釣合おもりレール部材１１を水平方向へ案内する。締付具１４を締め付けることにより、釣合おもりレール部材１１が折り返し傾斜部１３ｂにより案内されて上下の釣合おもりレール部材１１の水平方向位置が揃えられる。 The joint plate 13 has sufficient rigidity so that the intermediate portion of the folded inclined portion 13b does not easily deform along the rail flange portion 11b when the fastener 14 is tightened. The folded-back inclined portion 13b guides the counterweight rail member 11 in the horizontal direction when the fastener 14 is tightened. By tightening the fastener 14, the counterweight rail member 11 is guided by the folded inclined portion 13 b, and the horizontal positions of the upper and lower counterweight rail members 11 are aligned.
　このような釣合おもりレール継目板装置１２では、レールフランジ部１１ｂと平板部１３ａとが面で接触しているため、締付具１４のボルトを締め付けると、釣合おもりレール部材１１と継目板１３とは互いにＹ軸方向へ押し付けられる。このため、上下に隣接する２本の釣合おもりレール部材１１のＹ軸方向の位置が、平板部１３ａを基準に決められる。 In such a counterweight rail joint plate device 12, since the rail flange portion 11b and the flat plate portion 13a are in contact with each other, when the bolt of the fastener 14 is tightened, the counterweight rail member 11 and the joint plate are connected. 13 are pressed against each other in the Y-axis direction. For this reason, the position of the two counterweight rail members 11 adjacent to the upper and lower sides in the Y-axis direction is determined based on the flat plate portion 13a.
　一方、Ｘ軸方向に関しては、ボルトの締付前にはレールフランジ部１１ｂのレールブレード部１１ａとは反対側の端部と折り返し傾斜部１３ｂとの間に隙間が設けられている。この後、ボルトを締め付けるに従って、レールフランジ部１１ｂの端部と折り返し傾斜部１３ｂとが接触し隙間が閉じられる。 On the other hand, with respect to the X-axis direction, a gap is provided between the end of the rail flange portion 11b opposite to the rail blade portion 11a and the folded inclined portion 13b before tightening the bolt. Thereafter, as the bolt is tightened, the end of the rail flange portion 11b and the folded inclined portion 13b come into contact with each other and the gap is closed.
　このとき、折り返し傾斜部１３ｂと平板部１３ａとがつくる角度θが鋭角になっているため、左右のボルトを均等に締め付けることで、釣合おもりレール部材１１が中心軸Ｃに向かって押し出され、上下に隣接する２本の釣合おもりレール部材１１間のＸ軸方向の段差が解消される。 At this time, since the angle θ formed by the folded inclined portion 13b and the flat plate portion 13a is an acute angle, the counterweight rail member 11 is pushed toward the central axis C by evenly tightening the left and right bolts, The step in the X-axis direction between the two vertically opposite weight rail members 11 is eliminated.
　従って、釣合おもりレール部材１１として鋼板レールを用いる場合に、釣合おもりレール部材１１自体の形状を変更したり、微調整用のボルトを追加したりすることなく、釣合おもりレール部材１１の継目部分の位置調整を容易に行うことができる。 Therefore, when a steel plate rail is used as the counterweight rail member 11, the counterweight rail member 11 can be used without changing the shape of the counterweight rail member 11 itself or adding a bolt for fine adjustment. The position of the joint can be easily adjusted.
　図６は実施の形態１の釣合おもりレール継目板装置１２を図５とは異なる断面構造の釣合おもりレール部材１５に適用した例を示す断面図である。この例の釣合おもりレール部材１５は、断面が閉じた鋼板レールである。 6 is a cross-sectional view showing an example in which the counterweight rail joint plate device 12 of Embodiment 1 is applied to a counterweight rail member 15 having a cross-sectional structure different from that of FIG. The counterweight rail member 15 of this example is a steel plate rail having a closed cross section.
　実施の形態１の釣合おもりレール継目板装置１２は、このような釣合おもりレール部材１５にも適用でき、釣合おもりレール部材１５の継目部分の位置調整を容易に行うことができる。 The counterweight rail joint plate device 12 according to the first embodiment can be applied to such a counterweight rail member 15 and can easily adjust the position of the seam portion of the counterweight rail member 15.
　実施の形態２．
　次に、図７はこの発明の実施の形態２による釣合おもりレール継目板装置の断面図である。この例では、平板部１３ａに対して鋭角をなす折り返し傾斜部１３ｂが、平板部１３ａの幅方向の一端部のみに設けられている。そして、平板部１３ａの幅方向の他端部には、断面コ字形の折り返し当接部１３ｃが形成されている。折り返し当接部１３ｃには、レールフランジ部１１ｂのレールブレード部１１ａとは反対側の端面が当接されている。他の構成は、実施の形態１と同様である。 Embodiment 2. FIG.
Next, FIG. 7 is a cross-sectional view of a counterweight rail joint plate device according to Embodiment 2 of the present invention. In this example, a folded inclined portion 13b that forms an acute angle with respect to the flat plate portion 13a is provided only at one end portion in the width direction of the flat plate portion 13a. A folded contact portion 13c having a U-shaped cross section is formed at the other end in the width direction of the flat plate portion 13a. An end surface of the rail flange portion 11b opposite to the rail blade portion 11a is in contact with the folded contact portion 13c. Other configurations are the same as those in the first embodiment.
　このような釣合おもりレール継目板装置１２では、折り返し傾斜部１３ｂ側のボルトを締め付けることで、釣合おもりレール部材１１が折り返し当接部１３ｃに向かって押し出され、レールフランジ部１１ｂの端面が折り返し当接部１３ｃに当接される。これにより、上下に隣接する２本の釣合おもりレール部材１１間のＸ軸方向の段差が解消される。 In such a counterweight rail joint plate device 12, the counterweight rail member 11 is pushed out toward the return contact portion 13c by tightening the bolt on the side of the return inclined portion 13b, and the end surface of the rail flange portion 11b is It is brought into contact with the folded contact portion 13c. Thereby, the level | step difference of the X-axis direction between the two counterweight rail members 11 adjacent to the upper and lower sides is eliminated.
　また、全てのボルトを締め付けることにより、釣合おもりレール部材１１と継目板１３とは互いにＹ軸方向へ押し付けられる。このため、上下に隣接する２本の釣合おもりレール部材１１のＹ軸方向の位置が、平板部１３ａを基準に決められる。 Also, by tightening all the bolts, the counterweight rail member 11 and the joint plate 13 are pressed against each other in the Y-axis direction. For this reason, the position of the two counterweight rail members 11 adjacent to the upper and lower sides in the Y-axis direction is determined based on the flat plate portion 13a.
　従って、釣合おもりレール部材１１として鋼板レールを用いる場合に、釣合おもりレール部材１１自体の形状を変更したり、微調整用のボルトを追加したりすることなく、釣合おもりレール部材１１の継目部分の位置調整を容易に行うことができる。 Therefore, when a steel plate rail is used as the counterweight rail member 11, the counterweight rail member 11 can be used without changing the shape of the counterweight rail member 11 itself or adding a bolt for fine adjustment. The position of the joint can be easily adjusted.
　なお、実施の形態２の釣合おもりレール継目板装置１２は、図６に示したような釣合おもりレール部材１５にも適用できる。 Note that the counterweight rail joint plate device 12 of the second embodiment can also be applied to a counterweight rail member 15 as shown in FIG.
　実施の形態３．
　次に、図８はこの発明の実施の形態３による釣合おもりレール継目板装置を示す斜視図、図９は図８のＩＸ－ＩＸ線に沿う断面図である。実施の形態３の釣合おもりレール継目板装置１６は、平板を折り曲げ加工してなる継目板１７と、締付具１４とを有している。 Embodiment 3 FIG.

The flat plate portion 22a is in contact with the back surface of the rail flange portion 11b across the upper and lower counterweight rail members 11.
　折り返し当接部２２ｂは、継目板２２の幅方向両端部に設けられている。折り返し当接部２２ｂには、レールフランジ部１１ｂのレールブレード部１１ａとは反対側の端面（釣合おもりレール部材１１の幅方向の両端）が当接されている。 The folded contact portion 22b is provided at both ends of the seam plate 22 in the width direction. End surfaces (both ends in the width direction of the counterweight rail member 11) of the rail flange portion 11b opposite to the rail blade portion 11a are in contact with the folded contact portion 22b.
　締付部２２ｃ及び挿入部２２ｄは、継目板２２の幅方向中間部に設けられている。締付部２２ｃは、平板部２２ａから釣合おもりレール部材１１とは反対側へ直角に突出している。挿入部２２ｄは、平板部２２ａから釣合おもりレール部材１１側へ直角に突出し、レールブレード部１１ａの内側に挿入されている。 The tightening portion 22 c and the insertion portion 22 d are provided in the intermediate portion in the width direction of the joint plate 22. The tightening portion 22c protrudes at a right angle from the flat plate portion 22a to the side opposite to the counterweight rail member 11. The insertion portion 22d protrudes perpendicularly from the flat plate portion 22a to the counterweight rail member 11 side, and is inserted inside the rail blade portion 11a.
　レールフランジ部１１ｂには、複数の貫通孔１１ｃが設けられている。平板部２２ａには、貫通孔１１ｃに挿入された複数の突起２２ｅが設けられている。貫通孔１１ｃの径と突起２２ｅの径との間には、ある程度の余裕（遊び）が設けられている。 The rail flange portion 11b is provided with a plurality of through holes 11c.

As each fastener 23, a combination of a bolt and a nut is used. The bolt is arranged in parallel to the X axis, passes through the tightening portion 22c, and is screwed to the nut.
　締付具２３を締め付けることにより、締付部２２ｃ同士の間隔が狭くなり、折り返し当接部２２ｂ同士の間隔も狭くなる。これにより、レールフランジ部１１ｂの端面と折り返し当接部２２ｂとの間の隙間がなくなり、折り返し当接部２２ｂにより案内されて上下の釣合おもりレール部材１１の水平方向位置が揃えられる。他の構成は、実施の形態１と同様である。 By tightening the fastening tool 23, the interval between the tightening portions 22c is narrowed, and the interval between the folded contact portions 22b is also narrowed. Thereby, the clearance gap between the end surface of the rail flange part 11b and the folding | turning contact part 22b is lose | eliminated, and it guides by the folding | turning contact part 22b, and the horizontal direction position of the upper and lower counterweight rail member 11 is arrange | equalized.

The position adjustment of the joint portion of the weight rail member 11 can be easily performed.
　また、工場で締付部２２ｃに締付具２３を予め取り付けておくことにより、現場では上下の釣合おもりレール部材１１に継目板２２を嵌め込んで締付具２３締める作業のみで済み、据付時の作業効率を向上させることができる。 In addition, by attaching the fastening tool 23 to the fastening part 22c in advance at the factory, it is only necessary to fit the seam plate 22 to the upper and lower counterweight rail members 11 and tighten the fastening tool 23 on site. The working efficiency at the time can be improved.
　さらに、挿入部２２ｄがレールブレード部１１ａの内側に入り込んでいるので、レール断面の変形を防ぎ、強度を向上させることもできる。 Furthermore, since the insertion part 22d enters the inside of the rail blade part 11a, deformation of the rail cross section can be prevented and the strength can be improved.
　さらにまた、平板部２２ａに突起２２ｅを設けたので、締付具２３を締め付ける前に突起２２ｅを貫通孔１１ｃ（既設のボルト挿通孔）に挿入して継目板２２を釣合おもりレール部材１１に引っ掛けることができ、作業性を向上させることができる。 Furthermore, since the projection 22e is provided on the flat plate portion 22a, the projection 22e is inserted into the through hole 11c (existing bolt insertion hole) before the fastener 23 is tightened, and the seam plate 22 is attached to the counterweight rail member 11. It can be hooked and workability can be improved.
　また、締付具２３が上下方向に１列で済むため、２列必要だった従来品に比べて部品点数を削減することができるとともに、作業効率を向上させることができる。 Also, since the fasteners 23 need only be one row in the vertical direction, the number of parts can be reduced as compared with the conventional product that required two rows, and the work efficiency can be improved.
　なお、挿入部２２ｄの板ばね力で折り返し当接部２２ｂの間隔を狭めて折り返し当接部２２ｂ間に釣合おもりレール部材１１を把持するようにしてもよく、締付具２３の締付前にも継目板２２が釣合おもりレール部材１１から脱落するのを防止することができる。 Note that the counterweight rail member 11 may be held between the folded contact portions 22b by narrowing the interval between the folded contact portions 22b by the leaf spring force of the insertion portion 22d, and before the fastening tool 23 is tightened. In addition, it is possible to prevent the joint plate 22 from falling off the counterweight rail member 11.

　また、平板部２５ａに係合突起２５ｅを設けたので、締付具２３を締め付ける前に係合突起２５ｅを貫通孔１１ｃに挿入して継目板２５を釣合おもりレール部材１１に引っ掛けることができ、作業性を向上させることができる。 Further, since the engagement protrusion 25e is provided on the flat plate portion 25a, the engagement protrusion 25e can be inserted into the through hole 11c and the seam plate 25 can be hooked on the counterweight rail member 11 before the fastener 23 is tightened. Workability can be improved.
　さらに、継目板２５は２分割されているが、分割片２５－１，２５－２は対称形状であるため、部品を共通化でき、部品の種類は増加しない。 Furthermore, although the joint plate 25 is divided into two parts, since the divided pieces 25-1 and 25-2 are symmetrical, the parts can be shared and the types of parts do not increase.
　さらにまた、締付具２３が上下方向に１列で済むため、２列必要だった従来品に比べて部品点数を削減することができるとともに、作業効率を向上させることができる。 Furthermore, since the fasteners 23 need only be one row in the vertical direction, the number of parts can be reduced as compared with the conventional product that required two rows, and the work efficiency can be improved.
　なお、実施の形態１１の釣合おもりレール継目板装置２４は、図６に示したような釣合おもりレール部材１５にも適用できる。 Note that the counterweight rail joint plate device 24 of the eleventh embodiment can also be applied to the counterweight rail member 15 as shown in FIG.
　実施の形態１２．
　次に、図２１はこの発明の実施の形態１２による釣合おもりレール継目板装置の断面図である。実施の形態１２では、分割片２５－１，２５－２のいずれか一方、ここでは分割片２５－２に、レールブレード部１１ａの内側に挿入される挿入部２５ｄが折り曲げ形成されている。他の構成は、実施の形態１１と同様である。 Embodiment 12 FIG.
Next, FIG. 21 is a sectional view of a counterweight rail joint plate device according to Embodiment 12 of the present invention. In the twelfth embodiment, an insertion portion 25d inserted inside the rail blade portion 11a is bent and formed on one of the divided pieces 25-1, 25-2, here the divided piece 25-2. Other configurations are the same as those of the eleventh embodiment.
　このような構成では、分割片２５－１，２５－２が左右対称ではなくなるものの、挿入部２５ｄがレールブレード部１１ａの内側に挿入されるため、レール断面の変形を防ぎ、強度を向上させることができる。 In such a configuration, although the divided pieces 25-1 and 25-2 are not symmetrical, the insertion portion 25d is inserted inside the rail blade portion 11a, thereby preventing deformation of the rail cross section and improving the strength. Can do.
　実施の形態１３．
　次に、図２２はこの発明の実施の形態１３による釣合おもりレール継目板装置の断面図である。実施の形態１３では、レールブレード部１１ａの内側に挿入される挿入部２５ｆが分割片２５－１，２５－２とは別部材で構成されている。挿入部２５ｆの先端部は、断面コ字形に折り曲げ加工されている。挿入部２５ｆの基端部は、締付部２５ｃ間に挟持されている。他の構成は、実施の形態１１と同様である。 Embodiment 13 FIG.
Next, FIG. 22 is a sectional view of a counterweight rail joint plate device according to Embodiment 13 of the present invention. In the thirteenth embodiment, the insertion portion 25f inserted inside the rail blade portion 11a is constituted by a member different from the divided pieces 25-1 and 25-2. The distal end portion of the insertion portion 25f is bent into a U-shaped cross section. The proximal end portion of the insertion portion 25f is sandwiched between the tightening portions 25c. Other configurations are the same as those of the eleventh embodiment.
　このような構成では、左右対称の分割片２５－１，２５－２を用いつつ、単純な形状の挿入部２５ｆにより、レール断面の変形を防ぎ、強度を向上させることができる。 In such a configuration, the rail cross section can be prevented from being deformed and the strength can be improved by the insertion portion 25f having a simple shape while using the symmetrically divided pieces 25-1 and 25-2.
　なお、実施の形態１～１３において、締付具１４，２３を締め付けていくと、釣合おもりレール部材１１の断面が変形することが予想される。しかし、実際に適用される鋼板レールの板厚は十分に厚く、変形量は微小なため、影響は殆どないと言える。もし、鋼板レールの変形を防止するのであれば、鋼板レールに比べ継目板の板厚を薄くすることで、継目板が先に変形し鋼板レールの断面変形を抑制することができる。 In the first to thirteenth embodiments, when the fasteners 14 and 23 are tightened, it is expected that the cross section of the counterweight rail member 11 is deformed. However, it can be said that there is almost no influence because the thickness of the steel plate rail to be actually applied is sufficiently thick and the deformation amount is minute. If the deformation of the steel plate rail is to be prevented, the joint plate is deformed first and the cross-sectional deformation of the steel plate rail can be suppressed by making the thickness of the joint plate thinner than that of the steel plate rail.
　また、上記の例では、この発明を釣合おもりレール継目板装置に適用したが、かごレール継目板装置に適用してもよい。
　さらに、締付具はボルト及びナットの組み合わせに限定されない。
　さらにまた、巻上機２や釣合おもり６等のエレベータ機器の個数やレイアウトは、図１に限定されるものではない。例えば、釣合おもりを２個用い、釣合おもりガイドレールを２組用いるエレベータにもこの発明は適用できる。また、釣合おもりがかごの側方に配置される横落ちタイプのエレベータにもこの発明は適用できる。
　また、この発明が適用されるエレベータ装置のタイプは、図１のタイプに限定されるものではない。例えば、機械室レスエレベータ、２：１ローピング方式のエレベータ装置、ワンシャフトマルチカー方式のエレベータ装置、ダブルデッキエレベータ、又は油圧エレベータ等にも、この発明は適用できる。 In the above example, the present invention is applied to a counterweight rail joint plate device, but may be applied to a car rail joint plate device.
Furthermore, the fastener is not limited to a combination of bolts and nuts.
Furthermore, the number and layout of elevator devices such as the hoist 2 and the counterweight 6 are not limited to those shown in FIG. For example, the present invention can be applied to an elevator that uses two counterweights and two sets of counterweight guide rails. Further, the present invention can also be applied to a side-falling type elevator in which the counterweight is arranged on the side of the car.
Further, the type of the elevator apparatus to which the present invention is applied is not limited to the type shown in FIG. For example, the present invention can be applied to a machine room-less elevator, a 2: 1 roping type elevator device, a one-shaft multi-car type elevator device, a double deck elevator, a hydraulic elevator, or the like.
