Description

エレベーター装置Elevator equipment
　本発明は、乗りかごの位置を検出するエレベーター装置に関する。 The present invention relates to an elevator device that detects the position of a car.
　昇降路内の位置を示すコードを有する長尺体を昇降路内に設け、乗りかごに設けられる読み取り装置によってコードを読み取ることにより、乗りかごの位置を検出する技術が知られている。 A technology is known in which a long body having a code indicating the position in the hoistway is provided in the hoistway, and the position of the car is detected by reading the code with a reading device provided in the car.
　例えば、特許文献１に記載の従来技術では、データが記録された磁気テープがかごの昇降経路に沿って張設され、かごには磁気テープのデータを読み取る磁気センサが設けられる。 For example, in the conventional technology described in Patent Document 1, a magnetic tape on which data is recorded is stretched along the ascending/descending path of the car, and the car is provided with a magnetic sensor for reading the data on the magnetic tape.
特開２０１５－１１３１８０号公報JP, 2005-113180, A
　しかしながら、上記従来技術では、最上階からピット付近まで連続した磁気テープが、ガイドレールに固定される取付板に取り付けられている。このため、ガイドレールへの取付板の固定作業を要するので、磁気テープの施工時間が長くなってしまう。さらに、ガイドレールによって磁気テープを支持しているため、昇降方向に位置調整など状態を乗りかごの位置から確認する必要がある。このため、磁気テープの施工時間が長くなってしまう。また、偏荷重などにより乗りかごの着床位置が変化すると、着床精度が変動してしまう。 However, in the above conventional technology, a continuous magnetic tape from the top floor to the vicinity of the pit is attached to the mounting plate fixed to the guide rail. For this reason, the work of fixing the mounting plate to the guide rail is required, so that the construction time of the magnetic tape becomes long. Further, since the magnetic tape is supported by the guide rails, it is necessary to confirm the state such as position adjustment in the ascending/descending direction from the position of the car. For this reason, the construction time of the magnetic tape becomes long. Further, if the landing position of the car changes due to an unbalanced load, the landing accuracy will change.
　そこで、本発明は、着床精度を損なうことなく、コードを有する長尺体の施工時間を短縮できるエレベーター装置を提供する。 Therefore, the present invention provides an elevator device that can reduce the construction time of a long body having a cord without impairing the landing accuracy.
　上記課題を解決するために、本発明によるエレベーター装置は、昇降路内の位置を示すコードを有する長尺体を有し、乗りかごに設けられる検出装置によってコードを読み取るものであって、長尺体は、乗りかごもしくは釣合錘を案内するガイドレールを支持する複数のレールブラケットに固定される。
In order to solve the above problems, an elevator apparatus according to the present invention has an elongated body having a code indicating a position in a hoistway, and a code is read by a detection device provided in a car. The body is fixed to a plurality of rail brackets that support guide rails that guide the car or counterweight.
　本発明によれば、着床精度を損なうことなく、コードを有する長尺体の施工時間を短縮できる
　上記した以外の課題、構成および効果は、以下の実施形態の説明により明らかにされる。 ADVANTAGE OF THE INVENTION According to this invention, the construction time of the long body which has a cord can be shortened, without impairing the landing precision, and the subject other than the above, a structure, and an effect are clarified by the following description of embodiment.

Although not shown, the counterweight-side guide rails 8, the car-side guide rails 6, and the car-side guide rails 7 are also predetermined in the height direction of the hoistway, like the counterweight-side guide rails 9. It is supported by the rail brackets 11A to 11H, the rail brackets 11A to 11H, and the rail brackets 12A to 12H, which are arranged at intervals.
　レールブラケット１０Ａ～１０Ｈ、レールブラケット１１Ａ～１１Ｈおよびレールブラケット１２Ａ～１２Ｈは、所定寸法（例えば２５００ｍｍ以下）のピッチで精度良く固定されているものであり、所定の位置への取り付け精度が高い。さらに、これらレールブラケットは、ガイドレールを支持するために、大きな機械的な強度を有している。したがって、後述するように、レールブラケットによってコードテープを支持することにより、昇降路１内において、所定の位置に精度良く、かつ十分な強度でコードテープを支持することができる。 The rail brackets 10A to 10H, the rail brackets 11A to 11H, and the rail brackets 12A to 12H are precisely fixed at a pitch of a predetermined dimension (for example, 2500 mm or less), and have high mounting accuracy at a predetermined position. Further, these rail brackets have great mechanical strength for supporting the guide rails. Therefore, as will be described later, by supporting the code tape by the rail bracket, the code tape can be supported at a predetermined position in the hoistway 1 with high accuracy and sufficient strength.
　図２は、図１に示すレールブラケット１０Ｆが設けられる位置における平面図である。 2 is a plan view at a position where the rail bracket 10F shown in FIG. 1 is provided.
　図２に示すように、かご側ガイドレール６，７および釣合錘側ガイドレール８，９は、それぞれ、昇降路内壁に固定されるレールブラケット１１Ｆ，１２Ｆ，１１Ｆ，１０Ｆによって支持されている。すなわち、かご側ガイドレール６と釣合錘側ガイドレール８は、昇降路内壁に固定される共通のレールブラケット１１Ｆによって支持されている。また、かご側ガイドレール７は昇降路内壁の他の位置に固定されるレールブラケット１２Ｆによって支持され、釣合錘側ガイドレール９は昇降路内壁のさらに他の位置に固定されるレールブラケット１０Ｆによって支持されている。 As shown in FIG. 2, the car side guide rails 6 and 7 and the counterweight side guide rails 8 and 9 are supported by rail brackets 11F, 12F, 11F and 10F fixed to the inner wall of the hoistway, respectively. That is, the car side guide rail 6 and the counterweight side guide rail 8 are supported by the common rail bracket 11F fixed to the inner wall of the hoistway. The car side guide rail 7 is supported by a rail bracket 12F fixed to another position on the hoistway inner wall, and the counterweight side guide rail 9 is supported by a rail bracket 10F fixed on another position on the hoistway inner wall. It is supported.
　図２に示すように各レールブラケット１０Ｆ，１１Ｆ，１２Ｆにおいて乗りかご４と対向する部分には、昇降路の高さ方向に延びて配置されるコードテープ１３，１４，１５が固定されている。 As shown in FIG. 2, the code tapes 13, 14, 15 extending in the height direction of the hoistway are fixed to the portions of the rail brackets 10F, 11F, 12F facing the car 4.
　ここで、コードテープは、昇降路内の位置を示すコードを有する長尺体であり、乗りかごに設けられる検出装置によってコードを読み取ることにより、乗りかごの位置が検出される。例えば、コードは、幾何学的パターン（２値パターン、バーコードなど）によってテープ表面に表されて、乗りかごに設けられる光学センサによって読み取られたり、磁気的に記録されて、乗りかごに設けられる磁気センサによって読み取られたりする。 Here, the code tape is an elongated body having a code indicating the position in the hoistway, and the position of the car can be detected by reading the code with a detection device provided in the car. For example, the code is provided on the surface of the tape by a geometric pattern (binary pattern, bar code, etc.), read by an optical sensor provided on the car, or magnetically recorded and provided on the car. It may be read by a magnetic sensor.
　図２においては、レールブラケット１０Ｆ，１１Ｆ，１２Ｆにおいてコードテープを取り付けられる箇所を示すために、三つのコードテープ１３，１４，１５が示されているが、乗りかごの位置を検出するためには、少なくとも一つのコードテープが設けられていればよい。例えば、コードテープ１３だけが設けられる場合、図１に示すように、コードテープ１３は、レールブラケット１０Ａ～１０Ｈにそれぞれ取り付けられるコードテープ固定金具１６Ａ～１６Ｈによって、昇降路の高さ方向において所定の間隔（ｈ1～ｈ７≦所定寸法（例えば２５００ｍｍ））で固定される。なお、複数のコードテープを用いることにより、乗りかごの位置検出の信頼性を向上することができる。 In FIG. 2, three code tapes 13, 14 and 15 are shown in order to show the locations where the code tapes can be attached on the rail brackets 10F, 11F and 12F, but in order to detect the position of the car, It suffices that at least one code tape is provided. For example, when only the code tape 13 is provided, as shown in FIG. 1, the code tape 13 is fixed in the height direction of the hoistway by the code tape fixing fittings 16A to 16H attached to the rail brackets 10A to 10H, respectively. It is fixed at intervals (h1 to h7≦predetermined dimension (for example, 2500 mm)). By using a plurality of code tapes, the reliability of the position detection of the car can be improved.
　コードテープ１３の上端部は、図１に示すように、最上部のレールブラケット１０Ａに設けられるコードテープ頂部サポート１７によって支持される。また、コードテープ１３の下端部には、テンションウェート１８（錘）が接続されている。テンションウェート１８により、コードテープ１３はたるみなく設置される。なお、テンションウェート１８は、昇降路壁面に設けられる図示されない部材によって、横方向への揺れや振れが防止されていてもよい。 The upper end of the code tape 13 is supported by a code tape top support 17 provided on the uppermost rail bracket 10A, as shown in FIG. A tension weight 18 (weight) is connected to the lower end of the code tape 13. The tension weight 18 allows the code tape 13 to be installed without slack. The tension weight 18 may be prevented from swinging or shaking in the lateral direction by a member (not shown) provided on the wall surface of the hoistway.
　図示を省略するが、他のコードテープ１４，１５も、コードテープ１３と同様に、レールブラケット１１Ａ～１１Ｈおよびレールブラケット１２Ａ～１２Ｈによって支持される。 Although not shown, the other code tapes 14 and 15 are also supported by the rail brackets 11A to 11H and the rail brackets 12A to 12H, like the code tape 13.
　乗りかご４には、コードテープ１３，１４，１５と昇降路の高さ方向で連続して対向する位置に、それぞれコードテープ検出装置１９，２０，２１が取り付けられる。コードテープ検出装置１９，２０，２１は、それぞれコードテープ１３，１４，１５が有するコードを読み取る。 The codec detectors 19, 20, 21 are attached to the car 4 at positions that continuously oppose the code tapes 13, 14, 15 in the height direction of the hoistway. The code tape detectors 19, 20, and 21 read the codes of the code tapes 13, 14, and 15, respectively.
　図２においては、レールブラケット１０Ｆ，１１Ｆ，１２Ｆにそれぞれ設けられるコードテープ１３，１４，１５の各々について、コードテープ検出装置の設置位置を示すために、三つのコードテープ検出装置１９，２０，２１が示されているが、乗りかごの位置を検出するためには、少なくとも一つのコードテープに対向する一つのコードテープ検出装置が設けられていればよい。なお、複数のコードテープおよび複数のコードテープ検出装置を用いることにより、乗りかごの位置検出の信頼性を向上することができる。 In FIG. 2, for each of the code tapes 13, 14, 15 provided on each of the rail brackets 10F, 11F, 12F, three code tape detection devices 19, 20, 21 are provided to show the installation positions of the code tape detection devices. However, in order to detect the position of the car, one code tape detecting device facing at least one code tape may be provided. By using a plurality of code tapes and a plurality of code tape detection devices, it is possible to improve the reliability of the position detection of the car.
　図２中では、レールブラケット１０Ｆに設けられるコードテープ１３に対向するコードテープ検出装置１９は、乗りかご４の側面側に配置されているが、これに限らず、乗りかご４の背面側に配置されてもよい。 In FIG. 2, the code tape detection device 19 facing the code tape 13 provided on the rail bracket 10F is arranged on the side surface side of the car 4, but the invention is not limited to this and is arranged on the back side of the car 4. May be done.
　図３は、図１に示す釣合錘側ガイドレール９の最上部付近を示す正面図である。また、図４は、図１に示す釣合錘側ガイドレール９の最上部付近を示す平面図である。 FIG. 3 is a front view showing the vicinity of the uppermost portion of the counterweight-side guide rail 9 shown in FIG. FIG. 4 is a plan view showing the vicinity of the uppermost portion of the counterweight-side guide rail 9 shown in FIG.
　以下、図３および図４を参照しながら、図１に示すレールブラケットの構成、並びにコードテープ１３の支持構成について説明する。 The configuration of the rail bracket shown in FIG. 1 and the support configuration of the code tape 13 will be described below with reference to FIGS. 3 and 4.
　釣合錘側ガイドレール９の最上部付近の昇降路内壁面にはＬ字状のブラケット２２が固定される。また、釣合錘側ガイドレール９における、ブラケット２２に対向する位置には、Ｌ字状のブラケット２３が固定されている。ブラケット２２とブラケット２３は、両者の間に位置する一対のコードテープ固定用ブラケット２４（図４）によって接続されている。これらブラケット２２、ブラケット２３およびコードテープ固定用ブラケット２４によって、レールブラケット１０Ａが構成されている。 An L-shaped bracket 22 is fixed to the inner wall surface of the hoistway near the top of the counterweight-side guide rail 9. An L-shaped bracket 23 is fixed to the counterweight-side guide rail 9 at a position facing the bracket 22. The bracket 22 and the bracket 23 are connected by a pair of code tape fixing brackets 24 (FIG. 4) located between them. The bracket 22, the bracket 23, and the code tape fixing bracket 24 constitute a rail bracket 10A.
　一対のコードテープ固定用ブラケット２４の内、乗りかご４側に面したコードテープ固定用ブラケット（図４中、下側のコードテープ固定用ブラケット２４）には、コードテープ検出装置１９（図２）に対向するコードテープ１３の表面を覆うように、コードテープ固定金具１６Ａが配置される。このコードテープ固定金具１６Ａにより、コードテープ１３の上端部付近がレールブラケット１０Ａに固定されている。 Among the pair of code tape fixing brackets 24, the code tape fixing bracket facing the car 4 side (the lower code tape fixing bracket 24 in FIG. 4) has a code tape detecting device 19 (FIG. 2). 16 A of code tape fixing fittings are arrange|positioned so that the surface of the code tape 13 which opposes may be covered. The vicinity of the upper end of the code tape 13 is fixed to the rail bracket 10A by the code tape fixing metal fitting 16A.
　レールブラケット１０Ａの直下に位置するレールブラケット１０Ｂも、レールブラケット１０Ａと同様の構成を有している。レールブラケット１０Ｂには、コードテープ検出装置１９（図２）に対向するコードテープ１３の表面を覆うようにコードテープ固定金具１６Ｂが配置される。このコードテープ固定金具１６Ｂにより、コードテープ１３の他の位置がレールブラケット１０Ａに固定されている。 The rail bracket 10B located directly below the rail bracket 10A has the same configuration as the rail bracket 10A. A code tape fixing metal fitting 16B is arranged on the rail bracket 10B so as to cover the surface of the code tape 13 facing the code tape detecting device 19 (FIG. 2). The other position of the code tape 13 is fixed to the rail bracket 10A by the code tape fixing fitting 16B.
　なお、図示を省略するが、レールブラケット１０Ｂよりも下方に位置するレールブラケット１０Ｃ～１０Ｈも、レールブラケット１０Ａ，１０Ｂと同様の構成を有する。また、レールブラケット１０Ｃ～１０Ｈにそれぞれ取り付けられるコードテープ固定金具１６Ｃ～１６Ｈ（図１）によって、コードテープ１３の他の位置が固定されている。 Although illustration is omitted, the rail brackets 10C to 10H located below the rail bracket 10B also have the same configuration as the rail brackets 10A and 10B. Further, other positions of the code tape 13 are fixed by the code tape fixing fittings 16C to 16H (FIG. 1) attached to the rail brackets 10C to 10H, respectively.
　一方のコードテープ固定用ブラケット２４の上面には、一対のサポートブラケット２５，２６がそれぞれボルトによって固定されており、サポートブラケット２５，２６間には、両端部にそれぞれねじ部を有するサポートシャフト２７が挿入されている。サポートシャフト２７は、その両端部のねじ部に螺合するナットなどの固定金具２８，２９によって、サポートブラケット２５，２６に固定されている。サポートシャフト２７の中央部には、コードテープ１３の端部が巻き掛けられて支持されている。 A pair of support brackets 25 and 26 are respectively fixed to the upper surface of one of the code tape fixing brackets 24 by bolts, and a support shaft 27 having a screw portion at each end is provided between the support brackets 25 and 26. Has been inserted. The support shaft 27 is fixed to the support brackets 25 and 26 by fixing fittings 28 and 29 such as nuts that are screwed into the threaded portions at both ends thereof. The end of the code tape 13 is wound around and supported by the center of the support shaft 27.
　このような支持構成によれば、レールブラケット１０Ａの上方部における狭い空間内に、コードテープ１３の上端部を容易に、かつ、確実に支持固定することができる。また、コードテープ１３の端部をサポートシャフト２７に巻き掛けることにより、コードテープ１３の端部への機械的なダメージを緩和できる。 With such a support structure, the upper end of the code tape 13 can be easily and reliably supported and fixed in the narrow space above the rail bracket 10A. Further, by winding the end of the code tape 13 around the support shaft 27, mechanical damage to the end of the code tape 13 can be mitigated.
　図５は、図２のＡ－Ａ線に沿って釣合錘側ガイドレール９の最上部付近を示す側面図である。図中、乗りかご４は最上階に停止している。なお、乗りかご４は、かご上に、保守作業用のハンドレール５０を備えている。 FIG. 5 is a side view showing the vicinity of the uppermost part of the counterweight-side guide rail 9 along the line AA in FIG. In the figure, the car 4 is stopped on the top floor. The car 4 is provided with a handrail 50 for maintenance work on the car.
　釣合錘側ガイドレール９は、その最上部に隣接するレールブラケット１０Ａ、レールブラケット１０Ａの直下に位置して最上階に隣接するレールブラケット１０Ｂに固定されている。レールブラケット１０Ａ，１０Ｂの乗りかご４に面する側には、コードテープ１３が配置されている。コードテープ１３は、乗りかご４に固定されるコードテープ検出装置１９に対向するコードテープ１３の表面部を覆うように配置されるコードテープ固定金具１６Ａ，１６Ｂによって、各レールブラケット１０Ａ，１０Ｂに固定されている。 The counterweight-side guide rail 9 is fixed to the rail bracket 10A adjacent to the uppermost part thereof, and the rail bracket 10B adjacent to the uppermost floor, which is located immediately below the rail bracket 10A. A code tape 13 is arranged on the side of the rail brackets 10A, 10B facing the car 4. The code tape 13 is fixed to each rail bracket 10A, 10B by code tape fixing metal fittings 16A, 16B arranged so as to cover the surface of the code tape 13 facing the code tape detecting device 19 fixed to the car 4. Has been done.
　図５に示すように、乗りかご４が最上階に停止している場合、乗りかご４に設けられるコードテープ検出装置１９は、最上階に隣接するレールブラケット１０Ｂに取り付けられるコードテープ固定金具１６Ｂに対向している。このため、乗りかご４が最上階まで移動して停止するとき、移動中にコードテープ１３のコードを検出していたコードテープ検出装置１９は、コードテープ固定金具１６Ｂと対向することによって、コードを検出できなくなる。従って、このときのコードテープ検出装置１９の出力する検出信号は、コード情報を含む通常の検出信号と識別できる。そこで、本実施例では、コードテープ検出装置１９がコードテープ固定金具１６Ｂに対向するときにコードテープ検出装置１９が出力する検出信号に基づいて、昇降路内における乗りかご４の位置が最上階であることを検出する。 As shown in FIG. 5, when the car 4 is stopped on the top floor, the code tape detection device 19 provided on the car 4 is attached to the code tape fixing metal fitting 16B attached to the rail bracket 10B adjacent to the top floor. Facing each other. For this reason, when the car 4 moves to the uppermost floor and stops, the code tape detection device 19 that has detected the code of the code tape 13 during movement opposes the code tape fixing bracket 16B, thereby It cannot be detected. Therefore, the detection signal output from the code tape detecting device 19 at this time can be discriminated from the normal detection signal containing the code information. Therefore, in the present embodiment, the position of the car 4 in the hoistway is the uppermost floor based on the detection signal output by the code tape detecting device 19 when the code tape detecting device 19 faces the code tape fixing fitting 16B. Detect that there is.
　なお、上述の最上階以外の階床、すなわち中間階や最下階（図１参照）に乗りかご４が停止する場合も、同様に、乗りかごの位置を検出できる。すなわち、コードテープ検出装置１９が、レールブラケット１０Ｄにおけるコードテープ固定金具１６Ｄおよびレールブラケット１０Ｆにおけるコードテープ固定金具１６Ｆに対向するときに、コードテープ検出装置１９が出力する検出信号に基づいて、昇降路内における乗りかご４の位置がそれぞれ中間階および最下階であることを検出する。 Note that even if the car 4 stops on a floor other than the above-mentioned top floor, that is, the middle floor or the bottom floor (see FIG. 1), the position of the car can be detected in the same manner. That is, when the code tape detecting device 19 faces the code tape fixing metal fitting 16D in the rail bracket 10D and the code tape fixing metal fitting 16F in the rail bracket 10F, the hoistway is detected based on the detection signal output from the code tape detecting equipment 19. It is detected that the position of the car 4 in the inside is the middle floor and the bottom floor, respectively.
　上述の実施例１によれば、コードテープが、釣合錘側ガイドレールを支持するレールブラケットに固定される。レールブラケットは、釣合錘側ガイドレールを固定するために取り付け精度と機械的強度が確保されているので、コードテープをレールブラケットに固定することにより、コードテープの取り付け位置の精度と取り付け強度が自ずと確保できる。したがって、コードテープを、繁雑な位置合わせ作業をすることなく据え付けることができるので、コードテープの施工作業時間を低減できる。 According to the first embodiment described above, the code tape is fixed to the rail bracket that supports the counterweight-side guide rail. Since the rail bracket secures the mounting accuracy and mechanical strength for fixing the counterweight side guide rail, fixing the code tape to the rail bracket ensures the accuracy and the mounting strength of the code tape. It can be secured by itself. Therefore, the code tape can be installed without performing a complicated alignment work, and thus the work time of the code tape can be reduced.
　また、本実施例１によれば、コードテープがレールブラケットに固定されるので、コードテープを取り付けるために用いられる部材の増加が抑制できる。したがって、コードテープの支持構造が比較的簡単になり、コードテープの施工作業時間を低減できる。 Further, according to the first embodiment, since the code tape is fixed to the rail bracket, it is possible to suppress an increase in members used for attaching the code tape. Therefore, the supporting structure of the code tape becomes relatively simple, and the work time for working the code tape can be reduced.
　また、レールブラケットは所定の間隔（例えば、２５００ｍｍ以下）で、釣合錘側ガイドレールの最上部から最下部にわたって離散的に複数設けられるので、据え付け作業中および据え付け後において、コードテープの振れを防止することができる。 In addition, since the rail brackets are provided at a predetermined interval (for example, 2500 mm or less) in a discrete manner from the uppermost part to the lowermost part of the counterweight-side guide rail, the runout of the code tape is prevented during and after the installation work. Can be prevented.
　また、コードテープは、レールブラケットの構成部材に直接的に固定されるので、昇降路内において、レールブラケットの設置空間に配置される。このため、昇降路を大きくすることなく、コードテープを設置することができる。さらに、コードテープの設置に伴って、昇降路内の部材に主ロープが引っ掛かりやすくなるような不都合は発生しない。 Also, since the code tape is directly fixed to the constituent members of the rail bracket, it is placed in the installation space of the rail bracket in the hoistway. Therefore, the code tape can be installed without enlarging the hoistway. Further, with the installation of the code tape, the inconvenience that the main rope is easily caught by the member in the hoistway does not occur.
　また、レールブラケットを構成する部材に、コードテープの一部を覆う固定金具によってコードテープを固定することにより、コードテープ検出装置が固定金具と対向するときにコードテープ検出装置が出力する検出信号を、乗りかごの位置検出に用いることができる。例えば、乗りかごが所定の位置（例えば、建屋のいずれかの階床）に位置することを検出できる。この場合、乗りかごにおけるコードテープ検出装置の設置高さに応じて、レールブラケットを所定の間隔（例えば、２５００ｍｍ以下）に設置することにより、コードテープ検出装置と固定金具の位置合わせ作業が不要となるため、施工作業時間が低減できる。 In addition, by fixing the code tape to the member that constitutes the rail bracket with a fixing bracket that covers a part of the code tape, the detection signal output by the code tape detecting device when the code tape detecting device faces the fixing bracket is detected. , It can be used to detect the position of the car. For example, it can be detected that the car is located at a predetermined position (for example, one of the floors of the building). In this case, by installing the rail brackets at a predetermined interval (for example, 2500 mm or less) according to the installation height of the code tape detecting device in the car, the work of aligning the code tape detecting device and the fixing bracket is unnecessary. Therefore, the construction work time can be reduced.
　次に、図６および図７を参照しながら、本発明の実施例２であるエレベーター装置の構成について説明する。なお、主に、実施例１と異なる点について説明する。 Next, a configuration of an elevator apparatus that is Embodiment 2 of the present invention will be described with reference to FIGS. 6 and 7. The points different from the first embodiment will be mainly described.
　図６は、本実施例２におけるかご側ガイドレール７（図２参照）の最上部付近を示す正面図である。また、図７は、本実施例２におけるかご側ガイドレール７の最上部付近を示す平面図である。 FIG. 6 is a front view showing the vicinity of the uppermost portion of the car side guide rail 7 (see FIG. 2) in the second embodiment. Further, FIG. 7 is a plan view showing the vicinity of the uppermost portion of the car side guide rail 7 in the second embodiment.
　かご側ガイドレール７の最上部付近の昇降路内壁面には、レールブラケット１２Ａが固定されている。レールブラケット１２Ａは、昇降路内壁面に固定されるＬ字状のブラケット３０Ａと、ブラケット３０Ａの上部に搭載されて固定されるＬ字状のブラケット３１Ａから構成される。かご側ガイドレール７の上端部は、ブラケット３１Ａによって固定されて支持される。 A rail bracket 12A is fixed to the inner wall surface of the hoistway near the top of the car-side guide rail 7. The rail bracket 12A includes an L-shaped bracket 30A fixed to the inner wall surface of the hoistway, and an L-shaped bracket 31A mounted and fixed on the bracket 30A. The upper end of the car-side guide rail 7 is fixed and supported by the bracket 31A.
　ブラケット３０Ａおよびブラケット３１Ａの長手方向は、かご側ガイドレール７の長手方向に対して垂直な方向であり、ブラケット３０Ａの長手方向の寸法はブラケット３１Ａよりも長い。このため、ブラケット３０Ａおよびブラケット３１Ａは、かご側ガイドレール７から、かご側ガイドレール７の左右両側に張り出し、ブラケット３０Ａの張り出し長さはブラケット３１Ａよりも大きい。 The longitudinal direction of the bracket 30A and the bracket 31A is a direction perpendicular to the longitudinal direction of the car-side guide rail 7, and the longitudinal dimension of the bracket 30A is longer than that of the bracket 31A. Therefore, the bracket 30A and the bracket 31A project from the car side guide rail 7 to the left and right sides of the car side guide rail 7, and the projecting length of the bracket 30A is larger than that of the bracket 31A.
　かご側ガイドレール７の左右の一方の側（図６では右側）において、ブラケット３０Ａの張り出し部における乗りかご４に対向する位置に、コードテープ固定金具３２Ａによってコードテープ１５の上端部付近が固定される。コードテープ固定金具３２Ａは、実施例１（図３のコードテープ固定金具１６Ａ）と同様に、コードテープ検出装置２１（図２）に対向するコードテープ１５の表面を覆うように配置される。 On one of the left and right sides of the car-side guide rail 7 (on the right side in FIG. 6), the vicinity of the upper end of the code tape 15 is fixed by a code tape fixing metal fitting 32A at a position facing the car 4 in the protruding portion of the bracket 30A. It The code tape fixing metal fitting 32A is arranged so as to cover the surface of the code tape 15 facing the code tape detecting device 21 (FIG. 2), as in the first embodiment (code tape fixing metal fitting 16A of FIG. 3).
　レールブラケット１２Ａの直下に位置するレールブラケット１２Ｂも、レールブラケット１２Ａと同様にブラケット３０Ｂおよびブラケット３１Ｂから構成されている。レールブラケット１２Ｂにおいては、かご側ガイドレール７の左右両側の内、コードテープ１５が配置される側（図６では右側）におけるブラケット３１Ｂの張り出し長さがブラケット３１Ａよりも長い。このようにブラケット３１Ａよりも長く張り出したブラケット３１Ｂの張り出し部に、コードテープ固定金具３２Ｂによってコードテープ１５が固定される。このコードテープ固定金具３２Ｂも、コードテープ検出装置２１に対向するコードテープ１５の表面を覆うように配置される。 The rail bracket 12B located directly below the rail bracket 12A is also composed of a bracket 30B and a bracket 31B, similar to the rail bracket 12A. In the rail bracket 12B, the protruding length of the bracket 31B on the side on which the code tape 15 is arranged (the right side in FIG. 6) is longer than the bracket 31A on both the left and right sides of the car-side guide rail 7. In this way, the code tape 15 is fixed by the code tape fixing metal fitting 32B to the protruding portion of the bracket 31B protruding longer than the bracket 31A. The code tape fixing metal fitting 32B is also arranged so as to cover the surface of the code tape 15 facing the code tape detecting device 21.
　実施例1と同様に、コードテープ検出装置２１がコードテープ固定金具３２Ｂに対向するときにコードテープ検出装置２１が出力する検出信号に基づいて、昇降路内における乗りかご４の位置が最上階であることを検出することができる。 Similar to the first embodiment, the position of the car 4 in the hoistway is at the top floor based on the detection signal output by the code tape detecting device 21 when the code tape detecting device 21 faces the code tape fixing metal fitting 32B. Can be detected.
　なお、図示を省略するが、レールブラケット１２Ｂよりも下方に位置するレールブラケット１２Ｃ～１２Ｈも、レールブラケット１２Ｂと同様の構成を有する。 Although not shown, the rail brackets 12C to 12H located below the rail bracket 12B also have the same configuration as the rail bracket 12B.
　ブラケット３０Ａの張り出し部の上面には、一対のサポートブラケット３３，３４がそれぞれボルトによって固定されており、サポートブラケット３３，３４間には、両端部にそれぞれねじ部を有するサポートシャフト３５が挿入されている。サポートシャフト３５は、その両端部のねじ部に螺合するナットなどの固定金具３６，３７によって、サポートブラケット３３，３４に固定されている。サポートシャフト３５の中央部には、コードテープ１５の端部が巻き掛けられて支持されている。 A pair of support brackets 33 and 34 are fixed to the upper surface of the projecting portion of the bracket 30A by bolts, and a support shaft 35 having a threaded portion at each end is inserted between the support brackets 33 and 34. There is. The support shaft 35 is fixed to the support brackets 33 and 34 by fixing fittings 36 and 37 such as nuts that are screwed into the threaded portions at both ends thereof. The end of the code tape 15 is wound around and supported by the center of the support shaft 35.
　このような支持構成によれば、レールブラケット１２Ａの上方部における狭い空間内に、コードテープ１５の上端部を容易に、かつ、確実に支持固定することができる。また、コードテープ１５の端部をサポートシャフト３５に巻き掛けることにより、コードテープ１５の端部への機械的なダメージを緩和できる。 With such a support structure, the upper end of the code tape 15 can be easily and reliably supported and fixed in the narrow space above the rail bracket 12A. Further, by winding the end of the code tape 15 around the support shaft 35, mechanical damage to the end of the code tape 15 can be reduced.
