Abstract

In this elevator device, an auxiliary unlocking device is provided to a hoistway, and has a movable member that can move in a direction parallel to an opening-and-closing operation direction of a car door, and a guide member that guides the movement of the movable member. When the movable member is positioned in an unlocking position, the auxiliary unlocking device causes a car door locking device to permit an opening operation of the car door through the car door locking device making contact with the movable member instead of an unlocking member in an interlock device.

Description

エレベータ装置elevator equipment
　本開示は、エレベータ装置に関するものである。 The present disclosure relates to an elevator device.
　従来のエレベータ装置において、かごには、かごドアロック装置が設けられている。かごドアロック装置は、かごが戸開領域外で停止した場合、かご内からの操作によってかごドアが開方向へ動かされることを機械的に阻止する（例えば、特許文献１参照）。 In conventional elevator systems, the car is provided with a car door lock device. A car door lock device mechanically prevents the car door from being moved in the opening direction by an operation from inside the car when the car stops outside the door opening area (for example, see Patent Document 1).
特許第４２９２２０７号公報Patent No. 4292207
　上記のような従来のエレベータ装置では、例えば昇降路の頂部に設置されている機器に対する保守作業を行う場合、作業員は、乗場からかご上に移動し、かごを最上階に着床させる。そして、作業員は、固定装置によって昇降路に対してかごを固定する。固定装置は、例えば、ガイドレールのバッキングに掛けられる。 In the conventional elevator system as described above, for example, when performing maintenance work on equipment installed at the top of the hoistway, the worker moves from the landing to the top of the car and lands the car on the top floor. Then, the worker fixes the car to the hoistway using the fixing device. The fixing device is, for example, hung on the backing of the guide rail.
　固定装置をバッキングに掛けた後、ブレーキが解放されると、かごが上方又は下方へ動き、固定装置がバッキングに噛み合い、バッキングから固定装置を外すことが困難になることがある。 When the brake is released after the securing device is engaged with the backing, the car may move upward or downward, causing the securing device to engage the backing, making it difficult to remove the securing device from the backing.
　このような場合、作業員は、天井救出口からかご内に移動し、かごドア及び乗場ドアを手動により開方向へ移動させ、乗場に脱出することができる。 In such a case, the worker can move into the car through the ceiling rescue opening, manually move the car door and landing door in the opening direction, and escape to the landing.
　これに対して、かごを戸開領域外に停止させると、上記のかごドアロック装置によって、手動によるかごドアの開動作は阻止される。このため、かご上において保守作業を行う場合、かごを戸開領域に停止させておく必要があり、かご上から保守対象の機器までの距離が大きい場合、作業性が低下する。 On the other hand, when the car is stopped outside the door opening area, the car door locking device prevents the car door from being manually opened. Therefore, when performing maintenance work on the car, it is necessary to stop the car in an area where the door is open, and if the distance from the top of the car to the equipment to be maintained is long, work efficiency decreases.
　本開示は、上記のような課題を解決するためになされたものであり、かご上における保守作業の作業性を向上させることができるエレベータ装置を得ることを目的とする。 The present disclosure has been made to solve the above-mentioned problems, and aims to provide an elevator device that can improve the workability of maintenance work on a car.
　本開示に係るエレベータ装置は、昇降路を昇降するかご、かごに設けられているかごドア、乗場に設けられている乗場ドア、解錠部材を有しており、乗場ドアの開動作を阻止するインターロック装置、かごに設けられており、かごが戸開領域外に位置しているとき、かごドアの開動作を阻止し、かごが戸開領域内に位置しているとき、解錠部材に当たることによって、かごドアの開動作を許容するとともに、インターロック装置を解錠するかごドア施錠装置、及びかごドアの開閉動作方向に平行な方向へ移動可能な可動部材と、可動部材の移動を案内するガイド部材とを有しており、昇降路に設けられている補助解錠装置を備え、補助解錠装置は、真上から見て解錠部材と重なる位置である解錠位置に可動部材が位置しているとき、解錠部材の代わりに可動部材にかごドア施錠装置が当たることによって、かごドア施錠装置にかごドアの開動作を許容させる。 An elevator device according to the present disclosure includes a car that moves up and down a hoistway, a car door provided on the car, a landing door provided in a landing, and an unlocking member that prevents the opening operation of the landing door. An interlock device, which is provided on the car, prevents the car door from opening when the car is located outside the door opening area, and hits the unlocking member when the car is located within the door opening area. A car door locking device that allows the opening operation of the car door and unlocks the interlock device, a movable member that is movable in a direction parallel to the opening and closing direction of the car door, and guides the movement of the movable member. The auxiliary unlocking device has a movable member in an unlocking position that overlaps with the unlocking member when viewed from directly above. When the car door locking device is in the position, the car door locking device hits the movable member instead of the unlocking member, thereby allowing the car door locking device to open the car door.
　本開示のエレベータ装置によれば、かご上における保守作業の作業性を向上させることができる。 According to the elevator apparatus of the present disclosure, the workability of maintenance work on the car can be improved.

　かごドアフレーム３１上には、ドアモータ４０が固定されている。ドアモータ４０の回転は、第１かごドアプーリ３３に伝達される。第１かごドアプーリ３３が回転すると、駆動ベルト３５が循環するとともに、第２かごドアプーリ３４が回転する。これにより、第１かごドア７ａ及び第２かごドア７ｂが開閉動作する。 A door motor 40 is fixed on the car door frame 31. The rotation of the door motor 40 is transmitted to the first car door pulley 33. When the first car door pulley 33 rotates, the drive belt 35 circulates and the second car door pulley 34 rotates. As a result, the first car door 7a and the second car door 7b open and close.
　第１かごドア７ａには、支持板４４が固定されている。支持板４４には、第１平行リンク機構４５を介して、断面Ｌ字形の戸当たり側ブレード４６が取り付けられている。戸当たり側ブレード４６は、鉛直に配置されている。 A support plate 44 is fixed to the first car door 7a. A doorstop-side blade 46 having an L-shaped cross section is attached to the support plate 44 via a first parallel link mechanism 45 . The door stop side blade 46 is arranged vertically.
　第１平行リンク機構４５は、棒状の第１上部リンク４７と、Ｌ字形の第１下部リンク４８とを有している。 The first parallel link mechanism 45 has a rod-shaped first upper link 47 and an L-shaped first lower link 48.
　第１上部リンク４７の上端部は、回転軸４７ａを中心として回転可能に、支持板４４に取り付けられている。第１上部リンク４７の下端部は、戸当たり側ブレード４６の中間部に回転可能に連結されている。 The upper end of the first upper link 47 is rotatably attached to the support plate 44 about a rotating shaft 47a. A lower end portion of the first upper link 47 is rotatably connected to an intermediate portion of the door stop side blade 46.
　第１下部リンク４８の中間部は、回転軸４８ａを中心として回転可能に、支持板４４に取り付けられている。第１下部リンク４８の第１端部は、戸当たり側ブレード４６の下端部に回転可能に連結されている。 The intermediate portion of the first lower link 48 is rotatably attached to the support plate 44 about a rotating shaft 48a. A first end of the first lower link 48 is rotatably connected to a lower end of the doorstop side blade 46.
　第１下部リンク４８の中間部から第２端部までの部分は、戸当たり側ブレード４６と交差している。これにより、第１下部リンク４８の第２端部は、戸当たり側ブレード４６に対して回転軸４８ａとは反対側に突出している。 A portion of the first lower link 48 from the middle part to the second end intersects with the door stop side blade 46. As a result, the second end portion of the first lower link 48 protrudes with respect to the door stop side blade 46 on the opposite side of the rotating shaft 48a.
　第１下部リンク４８の第２端部には、フック状の施錠部分４８ｂが設けられている。また、第１下部リンク４８における戸当たり側ブレード４６と交差している部分と、施錠部分４８ｂとの間には、案内ローラ４１が回転可能に取り付けられている。第１下部リンク４８は、戸当たり側ブレード４６の動きに連動して、図３に示す解錠位置と、図４に示す施錠位置との間で回転変位可能になっている。 A hook-shaped locking portion 48b is provided at the second end of the first lower link 48. Further, a guide roller 41 is rotatably attached between the portion of the first lower link 48 that intersects with the door stop side blade 46 and the locking portion 48b. The first lower link 48 can be rotated between an unlocked position shown in FIG. 3 and a locked position shown in FIG. 4 in conjunction with the movement of the doorstop side blade 46.
　第２かごドア７ｂには、固定施錠子４２及び案内カム４９が固定されている。 A fixed locking element 42 and a guide cam 49 are fixed to the second car door 7b.
　案内カム４９の上面には、水平な案内面が形成されている。第１かごドア７ａ及び第２かごドア７ｂが全閉状態にあるとき、案内ローラ４１は案内カム４９の案内面上に位置しており、施錠部分４８ｂは図３に示す解錠位置に位置している。 A horizontal guide surface is formed on the upper surface of the guide cam 49. When the first car door 7a and the second car door 7b are in the fully closed state, the guide roller 41 is located on the guide surface of the guide cam 49, and the locking portion 48b is located in the unlocked position shown in FIG. ing.
　第１下部リンク４８に外力を与えずに第１かごドア７ａ又は第２かごドア７ｂを開方向へ移動させようとすると、図４に示すように、案内ローラ４１が案内カム４９から離れ、施錠部分４８ｂが施錠位置に移動する。この状態では、施錠部分４８ｂが固定施錠子４２に引っ掛かり、第１かごドア７ａ及び第２かごドア７ｂの開動作が阻止される。 When an attempt is made to move the first car door 7a or the second car door 7b in the opening direction without applying an external force to the first lower link 48, the guide roller 41 separates from the guide cam 49 and locks. Portion 48b moves to the locked position. In this state, the lock portion 48b is caught by the fixed lock 42, and the opening operations of the first car door 7a and the second car door 7b are blocked.
　戸当たり側ブレード４６は、第１上部リンク４７及び第１下部リンク４８の回転により、図３に示す解錠対応位置と、図４に示す施錠対応位置との間で、第１かごドア７ａに対して水平方向へ変位可能になっている。施錠対応位置は、解錠対応位置よりも戸袋側の位置である。 Due to the rotation of the first upper link 47 and the first lower link 48, the door stop side blade 46 is moved to the first car door 7a between the unlocking position shown in FIG. 3 and the locking position shown in FIG. In contrast, it can be displaced horizontally. The lockable position is a position closer to the door pocket than the unlockable position.
　また、戸当たり側ブレード４６は、重力又はばね力の作用により、戸袋側、即ち施錠対応位置側への力を常時受けている。しかし、第１かごドア７ａ及び第２かごドア７ｂが全閉状態にあるときは、案内ローラ４１が案内カム４９上に位置している。これにより、第１下部リンク４８が解錠位置に保持されるとともに、戸当たり側ブレード４６が戸当たり側、即ち解錠対応位置側に保持されている。 Further, the door stop side blade 46 is constantly receiving force toward the door bag side, that is, the locking corresponding position side, due to the action of gravity or spring force. However, when the first car door 7a and the second car door 7b are in the fully closed state, the guide roller 41 is located on the guide cam 49. As a result, the first lower link 48 is held at the unlocked position, and the door stop blade 46 is held at the door stop side, that is, the unlockable position side.
　支持板４４には、制限部材５０が設けられている。制限部材５０は、戸当たり側ブレード４６の戸当たり側への可動範囲を制限する。また、制限部材５０は、第１かごドア７ａ及び第２かごドア７ｂが全閉状態にあるとき、戸当たり側ブレード４６と間に多少の隙間が確保されるように配置されている。このため、戸当たり側ブレード４６を制限部材５０に接触させると、案内カム４９と案内ローラ４１との間に僅かな隙間が発生する。 A limiting member 50 is provided on the support plate 44. The limiting member 50 limits the movable range of the door stop side blade 46 toward the door stop side. Further, the restricting member 50 is arranged so that a certain gap is secured between the restricting member 50 and the doorstop side blade 46 when the first car door 7a and the second car door 7b are in a fully closed state. Therefore, when the doorstop side blade 46 is brought into contact with the limiting member 50, a slight gap is generated between the guide cam 49 and the guide roller 41.
　支持板４４には、第２平行リンク機構５２を介して、断面Ｌ字形の戸袋側ブレード５３が取り付けられている。第２平行リンク機構５２は、第２上部リンク５４及び第２下部リンク５５を有している。 A door pocket side blade 53 having an L-shaped cross section is attached to the support plate 44 via a second parallel link mechanism 52. The second parallel link mechanism 52 has a second upper link 54 and a second lower link 55.
　第２上部リンク５４の中間部は、回転軸５４ａを中心として回転可能に支持板４４に取り付けられている。第２上部リンク５４の第１端部は、戸袋側ブレード５３の中間部に回転可能に連結されている。 The middle portion of the second upper link 54 is rotatably attached to the support plate 44 about a rotating shaft 54a. The first end portion of the second upper link 54 is rotatably connected to the intermediate portion of the door pocket side blade 53.
　第２下部リンク５５の第１端部は、回転軸５５ａを中心として回転可能に、支持板４４に取り付けられている。第２下部リンク５５の第２端部は、戸袋側ブレード５３の下端部に回転可能に連結されている。 The first end of the second lower link 55 is rotatably attached to the support plate 44 about the rotating shaft 55a. The second end of the second lower link 55 is rotatably connected to the lower end of the door pocket side blade 53.
　戸袋側ブレード５３は、戸当たり側ブレード４６に平行、即ち鉛直に配置されている。また、戸袋側ブレード５３は、第２上部リンク５４及び第２下部リンク５５の回転により、水平方向へ変位可能になっている。 The door bag side blade 53 is arranged parallel to the door stop side blade 46, that is, vertically. Moreover, the door pocket side blade 53 can be displaced in the horizontal direction by rotation of the second upper link 54 and the second lower link 55.
　第１かごドア７ａの上部には、レバー５６が設けられている。レバー５６は、回転軸５６ａを中心として回転可能である。回転軸５６ａは、レバー５６の中間部に配置されている。レバー５６の第１端部には、レバー用ローラ５７が設けられている。 A lever 56 is provided at the top of the first car door 7a.
