SOLUTION: In two pairs of braking machines arranged in the hoisting machine, outer cylinders 12, 15 of releasing cables 11, 14 in one of both pairs of braking machines are held in predetermined positions to an operation apparatus 17 by means of a holding piece 27, and a traction action of core wires 13, 16 based on operation of the operation apparatus 17 is eliminated. In this way, a braking action in one of two pairs of braking machines is maintained in operation of the operation apparatus 17, while a braking action of the other is released, and braking ability is tested by carrying out braking operation in each of the two pairs. Therefore, a weight of a setting weight loaded into a car for setting a braking force of the hoisting machine is halved, so that labor and a working time for loading/unloading the setting weight in a braking action testing time can be reduced and braking force of the hoisting machine can be set easily.

Description

【発明の属する技術分野】
この発明は、制動用回転体をそれぞれ制動する二組の制動機が設けられたエレベーター巻上機の制動力設定装置に関する。
【0002】
【従来の技術】
図7〜図11は、例えば特開平8−40676号公報に示された構成に類似したエレベーター装置を示す図で、図7はエレベーターの構成を概念的に示す立面図、図8は図7における巻上機の制動力設定作業を説明する図、図9は図8における制動機の解放用ケーブルの配置を概念的に示す図、図10は図9の操作具の拡大図、図11は図10の正面図である。
【0003】
図において、1は昇降路、2は昇降路1の下部に設置された主索巻取り式の巻上機で、電動機3、駆動綱車4、ブレーキディスクすなわち制動用回転体5、制動用回転体5を制動する第一制動機6及び第一制動機6とは離れて配置されて制動用回転体5を制動する第二制動機7が設けられている。8は昇降路1の上部に互いに離れて枢着された滑車、9は昇降路1の所定経路を昇降するかごである。
【0004】
10は主索で、一端がかご9に連結されて上昇し滑車8に巻掛けられて、下降し巻上機2の駆動綱車4に巻掛けられている。11は第一制動機6の制動作用を解放する可撓性ケーブルからなる第一解放用ケーブルで、条体をなす外筒12及びこの外筒12に挿通された芯線13によって構成され、外筒12の一端は第一制動機6の固定部に固定され、また芯線13の一端は第一制動機6の解放レバーに連結されている。
【0005】
14は第二制動機7の制動作用を解放する可撓性ケーブルからなる第二解放用ケーブルで、条体をなす外筒15及びこの外筒15に挿通された芯線16によって構成され、外筒15の一端は第二制動機7の固定部に固定され、また芯線16の一端は第二制動機7の解放レバーに連結されている。17はかご9の異常停止時に第一制動機6及び第二制動機7の制動作用を解除してかご9を救出運転する操作具で、救出作業時に昇降路1の下部近くの乗場床に載置される操作具で、次に述べるように構成されている。
【0006】
すなわち、操作具17は鉛直部18を有する台からなる固定部19、鉛直部18面及び固定部19の台の面に長手が平行に配置された軸20及びL字状をなしL字の屈折部が軸20に枢持された操作レバー21が設けられている。そして、鉛直部18には第一解放用ケーブル11の外筒12の他端が締結され、また第二解放用ケーブル14の外筒15の他端が締結される。
【0007】
また、L字状の操作レバー21にはL字の一部からなり、軸20の長手方向における両側に上向きのL字短辺22が形成され、一方のL字短辺22には第一解放用ケーブル11の芯線13の他端が連結され、また他方のL字短辺22には第二解放用ケーブル14の芯線16の他端が連結される。
【0008】
23は巻上機2の制動力設定作業時にかご9に積み込まれる設定用おもりで、多数のおもり片からなり、定格積載荷重の二倍の重量が積み込まれて制動能力が検定される。なお、かご9の定格積載荷重の二倍の重量が巻上機2の制動作用の検定の基準として規定されている。
【0009】
上記のように構成されたエレベーター装置において、制動動作の信頼性を向上するため巻上機2に同じ制動能力を有する第一制動機6及び第二制動機7が設けられている。そして、巻上機2が付勢されると第一制動機6及び第二制動機7による制動が電磁動作によって解除されて駆動綱車4が回転する。これによって、主索10を介してかご9が昇降して所要の乗場に到達すると第一制動機6及び第二制動機7が、ばね動作によって制動用回転体5を押圧して制動動作し、停止したかご9がその位置に保持される。
【0010】
また、かご9の異常停止時にかご9を救出運転する場合には、操作具17が乗場床に仮設されて操作レバー21が作業員によって図11に示す矢印A方向へ押し下げられる。これにより、第一解放用ケーブル11の芯線13、第二解放用ケーブル14の芯線16が、外筒12、外筒15に対して牽引されて、第一制動機6及び第二制動機7のばね動作に抗して制動作用が解除される。
【0011】
次いで、かご9の重量によってかご9を昇降させて近くの乗場に対向した状態で、操作レバー21の押圧を止めて巻上機2をばね動作によって制動する。そして、この状態においてかご9内の乗客が乗場へ救出される。なお、制動作用の解除時に操作具17に設けられた一つの操作レバー21を一動作により操作することによって、すなわち簡易な操作によって容易に第一制動機6及び第二制動機7の制動作用を解除できるように構成されている。
【0012】
【発明が解決しようとする課題】
上記のようなエレベーター装置において、巻上機の制動力設定作業時に第一制動機及び第二制動機を制動動作させて、制動作用を同時に検定して制動力を設定することになる。したがって、制動作用の検定荷重として設定された基準の重量、例えばかご9に定格積載荷重の二倍の重量の設定用おもりを積み込む必要があって、多くの労力と作業時間を要するという問題点があった。
【0013】
この発明は、かかる問題点を解消するためになされたものであり、二組の制動機を有する巻上機が設けられたエレベーターにおいて容易に制動力を設定できるエレベーター巻上機の制動力設定装置を得ることを目的とする。
【0014】
【課題を解決するための手段】
この発明に係るエレベーター巻上機の制動力設定装置においては、巻上機に設けられた制動用回転体をそれぞれ制動する二組の制動機と、条体をなす外筒及びこの外筒に挿通された芯線によって構成された可撓性ケーブルからなり制動機のそれぞれに設けられて一端が制動機に連結され、芯線が牽引されて制動機の制動作用を解放する解放用ケーブルと、これらの解放用ケーブルの他端側における外筒がそれぞれ保持された固定部及びこの固定部に装備されて芯線がそれぞれ連結され芯線を牽引する操作レバーが設けられて、人為操作による操作レバーの操作を介して制動機の制動作用を解放する操作具とが設けられる。そして、一方の解放用ケーブルの他端側における外筒端部の操作具の固定部による保持を解除して操作レバーの操作による芯線の牽引作用が解消される。
【0015】
また、この発明に係るエレベーター巻上機の制動力設定装置においては、人為操作によって要時に一側が操作レバーに係止され、他側は一方の解放用ケーブルの他端側における外筒端部を保持して上記操作レバーの操作による上記芯線の牽引作用を解消する保持片が設けられる。
【0016】
また、この発明に係るエレベーター巻上機の制動力設定装置においては、巻上機の制動力設定作業時に操作具が、巻上機によって運転されるエレベーターの乗場床に仮設される。
【0017】
【発明の実施の形態】
実施の形態1.
図1〜図6は、この発明の実施の形態の一例を示す図で、図1は前述の図10相当図、図2は図1の正面図、図3は図1の保持片の拡大斜視図、図4は前述の図10に示す状態の操作具に保持片を装着する状況を説明する図、図5は図1における解放用ケーブルの動作状態を説明する図、図6は図1における解放用ケーブルの他の動作状態を説明する図である。なお、図1〜図6の他は前述の図7〜図11と同様にエレベーター装置が構成されている。
【0018】
図において、17はかご9の異常停止時に第一制動機6及び第二制動機7の制動作用を解除してかご9を救出運転する操作具で、救出作業時に昇降路1の下部近くの乗場床に載置される。また、操作具17は前述の図10と同様に構成されている。すなわち、操作具17は鉛直部18を有する台からなる固定部19、鉛直部18面及び固定部19の台の面に長手が平行に配置された軸20及びL字状をなしL字の屈折部が軸20に枢持された操作レバー21が設けられている。
【0019】
24はねじ棒の中心に芯線13、芯線16が挿通される貫通孔が設けられた端部金具である。そして、第一解放用ケーブル11の外筒12の操作具17側の端部及び第二解放用ケーブル14の外筒15の操作具17側の端部が、それぞれ操作具17の鉛直部18位置に配置されて、外筒12及び外筒15の端部にそれぞれ端部金具24が設けられる。また、端部金具24は操作具17の鉛直部18の上縁部に設けられて上方に開口した切欠部25に着脱可能に嵌合される。
【0020】
また、L字状の操作レバー21にはL字の一部からなり、操作レバー21の軸20における長手方向の両側に上向きのL字短辺22が形成され、一方のL字短辺22には第一解放用ケーブル11の芯線13の操作具17側の端部が連結され、また他方のL字短辺22には第二解放用ケーブル14の芯線16の操作具17側の端部が連結される。26は端部金具24にねじ込まれたナットで、操作具17の鉛直部18の両面又は後述する保持具の両面に配置される。
【0021】
27は帯板がL字状に屈折されてなる保持具で、L字の一辺には操作具17のL字短辺22の先端に嵌合する第一切欠部28が、またL字の他辺には端部金具24が嵌合する第二切欠部29が設けられ、要時に図4に示す状況を経て図1及び図2に示す状態に操作レバー21と端部金具24に係止される。
【0022】
上記のような構成において、前述の図7〜図11に示すエレベーター装置と同様に制動動作の信頼性を向上するため巻上機2に同じ制動能力を有する第一制動機6及び第二制動機7が設けられている。そして、巻上機2が付勢されると第一制動機6及び第二制動機7による制動が電磁動作によって解除されて駆動綱車4が回転する。これによって、主索10を介してかご9が昇降して所要の乗場に到達すると第一制動機6及び第二制動機7が、ばね動作によって制動用回転体5を押圧して制動動作し、停止したかご9がその位置に保持される。
【0023】
また、かご9の異常停止時にかご9を救出運転する場合には、操作具17が乗場床に仮設されて操作レバー21が作業員によって図11に示す矢印A方向へ押し下げられる。これにより、図5に示すように第一解放用ケーブル11の芯線13、第二解放用ケーブル14の芯線16が、外筒12、外筒15に対して牽引される。これにより、第一制動機6及び第二制動機7のばね動作に抗して制動作用が解除される。
【0024】
次いで、かご9の重量によってかご9を昇降させて近くの乗場に対向した状態で、操作レバー21の押圧を止めて巻上機2をばね動作によって制動する。そして、この状態においてかご9内の乗客が乗場へ救出される。なお、制動作用の解除時に操作具17に設けられた一つの操作レバー21を一動作により操作することによって、すなわち簡易な操作によって容易に第一制動機6及び第二制動機7の制動作用を解除できるように構成されている。
【0025】
また、巻上機2の制動力設定作業時には、先ず次に述べる準備作業が行われる。すなわち、操作具17が乗場床に仮設されて、前述の図10の状態において操作具17の固定部19、すなわち鉛直部18から第一解放用ケーブル11、第二解放用ケーブル14の一方の端部金具24が取り外される。
【0026】
以下、例えば第一解放用ケーブル11の芯線13の牽引作用を解消するものとして説明する。すなわち、第一解放用ケーブル11の端部金具24が、ナット26を緩めて固定部19の鉛直板18から取り外される。そして、図4に示す状態を経て保持具27の第一切欠部28が操作具17のL字短辺22の先端に嵌合されて保持される。
【0027】
また、保持具27の第二切欠部29が、操作具17の鉛直部18から取り外された第一解放用ケーブル11の端部金具24に嵌合されてナット26によって挟圧されて締結される。これによって、図1及び図2に示す状態となり、第一解放用ケーブル11の端部金具24、すなわち外筒12の操作具17側の端部は、第一解放用ケーブル11の芯線13の操作具17側の端部に対して、操作レバー21の回動動作に関わらず所定位置に保持される。
【0028】
したがって、操作レバー21が回動動作して変位し、第一解放用ケーブル11の芯線13の操作具17側の端部が移動しても、図6に示すようにその移動が第一解放用ケーブル11の配線の長手中間部における変位によって吸収される。このため、芯線13の第一制動機6側が変位することはなく、第一制動機6の制動作用が解除されることはない。
【0029】
したがって、このような装置構成において操作レバー21を操作して回動したときに、第一制動機6の制動作用が解除されず、第二解放用ケーブル14の芯線16のみが牽引されて動作して第二制動機7の制動作用が解除される。これにより、第一制動機6についてのみ巻上機2の制動力設定が行われる。
【0030】
このため、巻上機2の制動力設定のためにかご9に積み込まれる設定用おもり23の重量は、制動作用の検定荷重として設定された基準の重量、すなわちかご9に定格積載荷重の二倍の重量に対して1/2となる。例えば、かご9の定格積載荷重が450kgのときに、第一制動機6及び第二制動機7の両者の制動力設定を同時に行う場合には、設定用おもり23重量が900kgを要するが、上記両者の一方の制動力設定を行うときには450kgで済む。
【0031】
そして、かご9に450kgの設定用おもり23が積み込まれて、操作具17の操作レバー21が図2に示す矢印A方向に押し下げられる。これにより、第二制動機7の制動作用が解除され第一制動機6の制動作用によって、積み込まれた設定用おもり23に対応した吊持荷重が支持されることによって、第一制動機6の制動能力が検定される。
【0032】
このように、制動作用の検定荷重として設定用おもり23をかご9に積み込み、また撤去する作業の労力と作業時間が半減するので、容易に巻上機2の制動力を設定でき作業能率が向上し、費用を節減することができる。
【0033】
なお、上述の例において第一制動機6の制動能力の検定後に、第一解放用ケーブル11の外筒12の端部金具24が、保持具27から取り外されて操作具17の鉛直部18に装着される。そして、第二解放用ケーブル14の外筒12の端部金具24が操作具17の鉛直部18から取り外されて保持具27の第二切欠部29に装着される。
【0034】
この状態で、操作具17の操作レバー21が図2に示す矢印A方向に押し下げられる。これにより、第一制動機6の制動作用が解除され第二制動機7の制動作用によって、積み込まれた設定用おもり23に対応した吊持荷重が支持されて第二制動機7の制動能力が、第一制動機6における制動作用の検定と同様に検定される。また、巻上機2の制動力設定の作業時にエレベーターの乗場床に操作具17が仮設されるので、安定した場所において容易に操作具17を操作することができ作業能力を向上することができる。なお、この実施の形態における巻上機2は主索巻取り式のものであるが、これに限るものではなく、例えばトラクションシーブ式の巻上機であっても同様の効果を得ることが出来る。
【0035】
【発明の効果】
この発明は以上説明したように、巻上機に設けられた制動用回転体をそれぞれ制動する二組の制動機と、条体をなす外筒及びこの外筒に挿通された芯線によって構成された可撓性ケーブルからなり制動機のそれぞれに設けられて一端が制動機に連結され、芯線が牽引されて制動機の制動作用を解放する解放用ケーブルと、これらの解放用ケーブルの他端側における外筒がそれぞれ保持された固定部及びこの固定部に装備されて芯線がそれぞれ連結され芯線を牽引する操作レバーが設けられて、人為操作による操作レバーの操作を介して制動機の制動作用を解放する操作具とを設けたものである。そして、一方の解放用ケーブルの他端側における外筒端部の操作具の固定部による保持を解除して操作レバーの操作による芯線の牽引作用を解消するものである。
【0036】
このようにして、操作具の固定部による二組の制動機の一方の解放用ケーブルの外筒の保持を解除し、操作具の操作による芯線の牽引作用が解消される。このため、操作具の操作時に二組の制動機の一方の制動作用が継続し、他方の制動機の制動作用が解除されるので、二組の制動機を一組ずつ制動動作して制動能力を検定することができる。したがって、巻上機の制動力設定のためにかごに積み込む設定用おもりの重量を1/2とすることができる。これにより、制動作用の検定荷重として設定用おもりをかごに積み込み、また撤去する作業の労力と作業時間が減少するので、容易に巻上機の制動力を設定でき作業能率が向上し、費用を節減する効果がある。
【0037】
また、この発明は以上説明したように、人為操作によって要時に一側が操作レバーに係止され、他側は一方の解放用ケーブルの他端側における外筒端部を保持して操作レバーの操作による芯線の牽引作用を解消する保持片を設けたものである。
【0038】
このようにして、二組の制動機の一方の解放用ケーブルの外筒を保持片によって操作具に対して所定位置に保持し、操作具の操作による芯線の牽引作用が解消される。このため、操作具の操作時に二組の制動機の一方の制動作用が継続し、他方の制動機の制動作用が解除されるので、二組の制動機を一組ずつ制動動作して制動能力を検定することができる。したがって、巻上機の制動力設定のためにかごに積み込む設定用おもりの重量を1/2とすることができる。これにより、制動作用の検定荷重として設定用おもりをかごに積み込み、また撤去する作業の労力と作業時間が減少するので、容易に巻上機の制動力を設定でき作業能率が向上し、費用を節減する効果がある。
【0039】
また、この発明は以上説明したように、巻上機の制動力設定作業時に操作具を、巻上機によって運転されるエレベーターの乗場床に仮設するものである。
【0040】
このようにして、エレベーターの乗場床に仮設された操作具の固定部による二組の制動機の一方の解放用ケーブルの外筒の保持を解除し、操作具の操作による芯線の牽引作用が解消される。このため、操作具の操作時に二組の制動機の一方の制動作用が継続し、他方の制動機の制動作用が解除されるので、二組の制動機を一組ずつ制動動作して制動能力を検定することができる。したがって、乗場床に仮設された操作具を容易に操作でき、また巻上機の制動力設定のためにかごに積み込む設定用おもりの重量を1/2とすることができる。このため、制動作用の検定荷重として設定用おもりをかごに積み込み、また撤去する作業の労力と作業時間が減少するので、容易に巻上機の制動力を設定でき作業能率が向上し、費用を節減する効果がある。
また、巻上機の制動力設定の作業時にエレベーターの乗場床に操作具が仮設されるので、安定した場所において容易に操作具を操作することができ作業能力を向上する効果がある。

[0002]
[Prior art]
FIGS. 7 to 11 are views showing an elevator apparatus similar to the structure shown in, for example, Japanese Patent Laid-Open No. 8-40676, FIG. 7 is an elevation view conceptually showing the structure of the elevator, and FIG. FIG. 9 conceptually shows the arrangement of the brake release cable in FIG. 8, FIG. 10 is an enlarged view of the operating tool in FIG. 9, and FIG. It is a front view of FIG.
[0003]
In the figure, 1 is a hoistway, 2 is a main rope winding type hoist installed at the lower part of the hoistway 1, and includes an electric motor 3, a driving sheave 4, a brake disk, that is, a braking rotator 5, and a braking rotation. A first brake 6 that brakes the body 5 and a second brake 7 that is disposed apart from the first brake 6 and brakes the brake rotating body 5 are provided. A pulley 8 is pivotally attached to the upper part of the hoistway 1 so as to be separated from each other, and a car 9 moves up and down a predetermined route of the hoistway 1.
[0004]
Reference numeral 10 denotes a main rope, one end of which is connected to the car 9 and ascends and is wound around the pulley 8, and descends and is wound around the driving sheave 4 of the hoisting machine 2. Reference numeral 11 denotes a first release cable made of a flexible cable that releases the braking action of the first brake 6, and includes an outer cylinder 12 that forms a strip and a core wire 13 that is inserted through the outer cylinder 12. One end of 12 is fixed to a fixing portion of the first brake 6, and one end of the core wire 13 is connected to a release lever of the first brake 6.
[0005]
Reference numeral 14 denotes a second release cable made of a flexible cable that releases the braking action of the second brake 7, and includes an outer cylinder 15 that forms a strip and a core wire 16 that is inserted through the outer cylinder 15. One end of 15 is fixed to a fixing portion of the second brake 7, and one end of the core wire 16 is connected to a release lever of the second brake 7. Reference numeral 17 denotes an operating tool for releasing the braking action of the first brake 6 and the second brake 7 when the car 9 is abnormally stopped, and performing a rescue operation of the car 9. The operation tool is arranged as described below.
[0006]
That is, the operating tool 17 has a fixed portion 19 composed of a table having a vertical portion 18, a vertical portion 18 surface, and a shaft 20 arranged in parallel to the surface of the fixed portion 19 in parallel with the length, and an L-shaped refraction. An operating lever 21 whose part is supported by the shaft 20 is provided. The other end of the outer cylinder 12 of the first release cable 11 is fastened to the vertical portion 18, and the other end of the outer cylinder 15 of the second release cable 14 is fastened.
[0007]
The L-shaped operating lever 21 is formed of a part of the L-shape, and has an upward L-shaped short side 22 formed on both sides in the longitudinal direction of the shaft 20. The other end of the core wire 13 of the cable 11 is connected, and the other L-shaped short side 22 is connected to the other end of the core wire 16 of the second release cable 14.
[0008]
Reference numeral 23 denotes a setting weight to be loaded on the car 9 at the time of setting the braking force of the hoisting machine 2. The setting weight 23 is composed of a large number of weight pieces, and the weight of twice the rated load is loaded to test the braking ability. In addition, twice the weight of the rated load of the car 9 is defined as a standard for testing the braking action of the hoisting machine 2.
[0009]
In the elevator apparatus configured as described above, the hoisting machine 2 is provided with the first brake 6 and the second brake 7 having the same braking capability in order to improve the reliability of the braking operation. When the hoisting machine 2 is energized, braking by the first brake 6 and the second brake 7 is released by electromagnetic operation, and the drive sheave 4 rotates. As a result, when the car 9 moves up and down via the main rope 10 and reaches the required landing, the first brake 6 and the second brake 7 press the braking rotator 5 by a spring operation to perform a braking operation, The stopped car 9 is held in that position.
[0010]
When the car 9 is rescued when the car 9 stops abnormally, the operating tool 17 is temporarily installed on the landing floor and the operating lever 21 is pushed down in the direction of arrow A shown in FIG. As a result, the core wire 13 of the first release cable 11 and the core wire 16 of the second release cable 14 are pulled with respect to the outer cylinder 12 and the outer cylinder 15, and the first brake 6 and the second brake 7. The braking action is released against the spring action.
[0011]

[0019]
Reference numeral 24 denotes an end fitting provided with a through hole through which the core wire 13 and the core wire 16 are inserted at the center of the screw rod. The end of the outer cylinder 12 of the first release cable 11 on the side of the operating tool 17 and the end of the outer cylinder 15 of the second release cable 14 on the side of the operating tool 17 are positioned at the position of the vertical portion 18 of the operating tool 17. End fittings 24 are provided at the ends of the outer cylinder 12 and the outer cylinder 15, respectively. The end fitting 24 is detachably fitted to a notch 25 provided on the upper edge of the vertical portion 18 of the operating tool 17 and opening upward.
[0020]
The L-shaped operation lever 21 is formed of a part of the L-shape, and an upward L-shaped short side 22 is formed on both sides in the longitudinal direction of the shaft 20 of the operation lever 21. Is connected to the end of the core wire 13 of the first release cable 11 on the operation tool 17 side, and the other L-shaped short side 22 is connected to the end of the core wire 16 of the second release cable 14 on the operation tool 17 side. Connected. A nut 26 is screwed into the end fitting 24 and is arranged on both surfaces of the vertical portion 18 of the operation tool 17 or both surfaces of a holder described later.
[0021]
27 is a holder in which the belt plate is refracted into an L-shape. A first notch 28 that fits on the tip of the L-short side 22 of the operation tool 17 is provided on one side of the L-shape, and an L-shape is also provided. On the other side, a second notch 29 for fitting the end fitting 24 is provided. When necessary, the second lever 29 is engaged with the operation lever 21 and the end fitting 24 in the state shown in FIGS. Is done.
[0022]
In the configuration as described above, the first brake 6 and the second brake having the same braking ability in the hoisting machine 2 in order to improve the reliability of the braking operation as in the elevator apparatus shown in FIGS. 7 to 11 described above. 7 is provided. When the hoisting machine 2 is energized, braking by the first brake 6 and the second brake 7 is released by electromagnetic operation, and the drive sheave 4 rotates. As a result, when the car 9 moves up and down via the main rope 10 and reaches the required landing, the first brake 6 and the second brake 7 press the braking rotator 5 by a spring operation to perform a braking operation, The stopped car 9 is held in that position.
[0023]
When the car 9 is rescued when the car 9 stops abnormally, the operating tool 17 is temporarily installed on the landing floor and the operating lever 21 is pushed down in the direction of arrow A shown in FIG. Thereby, as shown in FIG. 5, the core wire 13 of the first release cable 11 and the core wire 16 of the second release cable 14 are pulled with respect to the outer cylinder 12 and the outer cylinder 15. As a result, the braking action is released against the spring action of the first brake 6 and the second brake 7.
[0024]
Next, in a state where the car 9 is raised and lowered by the weight of the car 9 and is opposed to a nearby landing, the pressing of the operation lever 21 is stopped and the hoisting machine 2 is braked by a spring action. In this state, the passenger in the car 9 is rescued to the landing. It should be noted that the braking action of the first brake 6 and the second brake 7 can be easily performed by operating one operating lever 21 provided on the operating tool 17 by one operation when releasing the braking action, that is, by a simple operation. It is configured so that it can be released.
[0025]
Further, at the time of the braking force setting operation of the hoisting machine 2, the following preparation operation is first performed. That is, the operating tool 17 is temporarily installed on the landing floor, and in the state of FIG. 10 described above, one end of the first releasing cable 11 and the second releasing cable 14 from the fixing portion 19 of the operating tool 17, that is, the vertical portion 18. The metal part 24 is removed.
[0026]
Hereinafter, for example, it is assumed that the pulling action of the core wire 13 of the first release cable 11 is eliminated. That is, the end fitting 24 of the first release cable 11 is removed from the vertical plate 18 of the fixing portion 19 by loosening the nut 26. Then, through the state shown in FIG. 4, the first notch 28 of the holder 27 is fitted and held at the tip of the L-shaped short side 22 of the operation tool 17.
[0027]
Further, the second notch portion 29 of the holder 27 is fitted into the end fitting 24 of the first release cable 11 removed from the vertical portion 18 of the operation tool 17, and is clamped and fastened by the nut 26. . 1 and 2, the end fitting 24 of the first release cable 11, that is, the end of the outer cylinder 12 on the operation tool 17 side is operated on the core wire 13 of the first release cable 11. The tool 17 is held at a predetermined position with respect to the end portion on the tool 17 side regardless of the rotation operation of the operation lever 21.
[0028]
Therefore, even if the operation lever 21 is rotated and displaced, and the end of the core wire 13 of the first release cable 11 on the side of the operation tool 17 moves, the movement is performed as shown in FIG. It is absorbed by the displacement in the longitudinal intermediate portion of the wiring of the cable 11. For this reason, the first brake 6 side of the core wire 13 is not displaced, and the braking action of the first brake 6 is not released.
[0029]
Therefore, when the operation lever 21 is operated and rotated in such a device configuration, the braking action of the first brake 6 is not released, and only the core wire 16 of the second release cable 14 is pulled and operated. Thus, the braking action of the second brake 7 is released. Thereby, the braking force setting of the hoisting machine 2 is performed only for the first brake 6.
[0030]
For this reason, the weight of the setting weight 23 loaded on the car 9 for setting the braking force of the hoisting machine 2 is the reference weight set as the test load for the braking action, that is, twice the rated load on the car 9. It becomes 1/2 with respect to the weight of. For example, when setting the braking force of both the first brake 6 and the second brake 7 at the same time when the rated load of the car 9 is 450 kg, the weight 23 for setting requires 900 kg. When setting the braking force of one of them, only 450 kg is required.
[0031]
Then, the setting weight 23 of 450 kg is loaded on the car 9, and the operation lever 21 of the operation tool 17 is pushed down in the direction of arrow A shown in FIG. As a result, the braking action of the second brake 7 is released and the suspension load corresponding to the loaded setting weight 23 is supported by the braking action of the first brake 6, whereby the first brake 6 The braking ability is verified.
[0032]
As described above, the setting weight 23 is loaded into the car 9 as a test load for the braking action, and the labor and time for the removal work are halved, so that the braking force of the hoist 2 can be easily set and the work efficiency is improved. And save money.
[0033]
In the above-described example, after the verification of the braking ability of the first brake 6, the end fitting 24 of the outer cylinder 12 of the first release cable 11 is removed from the holding tool 27 and placed on the vertical part 18 of the operating tool 17. Installed. Then, the end fitting 24 of the outer cylinder 12 of the second release cable 14 is detached from the vertical portion 18 of the operation tool 17 and attached to the second notch 29 of the holder 27.
[0034]
In this state, the operating lever 21 of the operating tool 17 is pushed down in the direction of arrow A shown in FIG. As a result, the braking action of the first brake 6 is released and the suspension load corresponding to the loaded setting weight 23 is supported by the braking action of the second brake 7, and the braking ability of the second brake 7 is increased. The test is performed in the same manner as the test of the braking action in the first brake 6. In addition, since the operating tool 17 is temporarily installed on the elevator floor during the work of setting the braking force of the hoisting machine 2, the operating tool 17 can be easily operated in a stable place, and the work ability can be improved. . The hoisting machine 2 in this embodiment is of a main rope winding type, but is not limited to this, and the same effect can be obtained even with a traction sheave type hoisting machine, for example. .
