Abstract

An elevator control panel comprises a support body positioned inside a hoistway, a rotating member that is capable of rotating around a rotating shaft disposed on the support body, a device subject to maintenance that is disposed on the rotating member, and an operating member that extends downward from the rotating member. The device subject to maintenance is displaced in relation to the support body by the rotation of the rotating member between a normal position positioned above the rotating shaft, and an inspection position positioned below the rotating shaft. The operating member forces the rotating member to rotate in the direction in which the device subject to maintenance is displaced from the normal position to the inspection position, by receiving a pull-down force from the outside.

　従来、昇降路内に設置された制御盤に対してかご上からの保守点検作業を容易に行うために、複数の部分制御盤を互いに連結することにより制御盤を折りたたみ可能としたエレベータが提案されている。この従来のエレベータでは、通常運転時に、制御盤が折りたたまれた状態で昇降路内の上端部に保持され、保守点検時に、制御盤の折りたたみ状態を解除して各部分制御盤が一列に吊り下がるようになっている。保守点検時には、かごを上下に移動させることにより、かご上の作業者が各部分制御盤の位置に容易に達することができる（特許文献１参照）。 Conventionally, an elevator has been proposed in which a control panel can be folded by connecting a plurality of partial control panels to each other in order to easily perform maintenance and inspection work on the control panel installed in the hoistway. ing. In this conventional elevator, during normal operation, the control panel is folded and held at the upper end of the hoistway, and during maintenance, the control panel is released from the folded state and each partial control panel is suspended in a line. It is like that. At the time of maintenance and inspection, the worker on the car can easily reach the position of each partial control panel by moving the car up and down (see Patent Document 1).

　しかし、制御盤が昇降路内のピット部に設置されている場合には、作業者がかご上に乗って保守点検作業を行うことができないので、昇降路内の床に足場台（例えば脚立等）を置いて、足場台に乗った作業者が制御盤に対して保守点検作業を行うこととなる。 However, when the control panel is installed in the pit part in the hoistway, the operator cannot get on the car to perform maintenance and inspection work. ), And the worker on the scaffolding will perform maintenance and inspection work on the control panel.
　ここで、昇降路内には、かごや釣合おもり等、複数の機器が配置されているので、昇降路内で制御盤を配置するスペースを水平方向について広げるには限界がある。従って、制御盤の容積を確保するためには、制御盤の高さ寸法を大きくする必要がある。 Here, since a plurality of devices such as a car and a counterweight are arranged in the hoistway, there is a limit in expanding the space for arranging the control panel in the hoistway in the horizontal direction. Therefore, in order to ensure the volume of the control panel, it is necessary to increase the height dimension of the control panel.
　しかし、足場台に乗っても作業者が届かないような高い位置（例えば、足場台の上面から１８００ｍｍの高さよりも上方の位置）に保守点検の対象となる機器（保守対象機器）を配置しても、作業者は保守対象機器の保守点検作業を行うことができない。従って、従来、作業者が届かないような高い位置には、保守点検の対象とはならない故障しにくい機器（例えば回生抵抗等）のみしか配置することができず、保守対象機器を設置する位置が制限されてしまう。 However, the equipment (maintenance target equipment) that is subject to maintenance inspection is placed at a high position (for example, a position higher than the height of 1800 mm from the top surface of the scaffold base) so that the worker does not reach even if it gets on the scaffold base. However, the operator cannot perform maintenance and inspection work on the maintenance target device. Therefore, conventionally, only high-resistance devices that are not subject to maintenance and inspection (for example, regenerative resistors) can be placed at high positions where workers cannot reach. It will be restricted.
　この発明は、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、保守対象機器のレイアウトの自由度を向上させることができるエレベータの制御盤を得ることを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain an elevator control panel capable of improving the degree of freedom of layout of maintenance target devices.
　この発明によるエレベータの制御盤は、昇降路内に配置された支持体、支持体に設けられた回動軸を中心に回動可能な回動部材、回動部材に設けられ、回動部材の回動により、回動軸よりも上方に位置する通常位置と、回動軸よりも下方に位置する点検位置との間で支持体に対して変位される保守対象機器、及び回動部材から下方へ延び、外部からの引き下げ力を受けることにより、保守対象機器が通常位置から点検位置へ変位する方向へ回動部材を回動させる操作部材を備えている。 An elevator control panel according to the present invention includes a support disposed in a hoistway, a rotation member rotatable about a rotation shaft provided on the support, and a rotation member. The maintenance target device that is displaced with respect to the support between the normal position positioned above the rotation axis and the inspection position positioned below the rotation axis by the rotation, and the rotation member And an operation member that rotates the rotation member in a direction in which the maintenance target device is displaced from the normal position to the inspection position by receiving a pulling force from the outside.
　この発明によるエレベータの制御盤では、支持体に設けられた回動軸を中心に回動可能な回動部材に保守対象機器が設けられ、回動部材の回動により、回動軸よりも上方に位置する通常位置と、回動軸よりも下方に位置する点検位置との間で保守対象機器が変位されるので、通常運転時には、作業者の届かないアクセス不可領域に保守対象機器を配置しておき、保守点検時にのみ、作業者による保守点検が可能なアクセス可能領域へ保守対象機器を変位させることができる。これにより、制御盤の設置スペースを水平方向について広げずに、保守対象機器のレイアウトの自由度を向上させることができる。 In the elevator control panel according to the present invention, the maintenance target device is provided on the rotating member that is rotatable about the rotating shaft provided on the support body, and the rotating member rotates to move upward from the rotating shaft. Because the maintenance target device is displaced between the normal position located at the position and the inspection position located below the rotation axis, the maintenance target device is placed in an inaccessible area where the worker cannot reach during normal operation. In addition, the maintenance target device can be displaced to an accessible area where maintenance inspection can be performed by an operator only during maintenance inspection. Thereby, the freedom degree of the layout of a maintenance object apparatus can be improved, without expanding the installation space of a control panel about a horizontal direction.

　以下、この発明の好適な実施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によるエレベータの制御盤が昇降路内に設置されている状態を示す正面図である。図において、かご及び釣合おもり（いずれも図示せず）が昇降される昇降路内のピット部には、エレベータの運転を制御する制御盤１が設置されている。この例では、制御盤１は、機械室が設けられていない機械室レスエレベータの制御盤とされている。制御盤１は、水平方向についてかご及び釣合おもりを避けて配置されている。 Preferred embodiments of the present invention will be described below with reference to the drawings.
Embodiment 1 FIG.
FIG. 1 is a front view showing a state in which an elevator control panel according to Embodiment 1 of the present invention is installed in a hoistway. In the figure, a control panel 1 for controlling the operation of the elevator is installed in a pit portion in a hoistway where a car and a counterweight (both not shown) are raised and lowered. In this example, the control panel 1 is a machine room-less elevator control panel in which no machine room is provided. The control panel 1 is arranged so as to avoid a car and a counterweight in the horizontal direction.
　制御盤１に対する保守点検作業を行うときには、足場台２が昇降路のピット面（床面）３に置かれる。作業者は、ピット面３に置かれた足場台２の上面に乗った状態で、制御盤１に対して保守点検作業を行う。 When performing maintenance and inspection work on the control panel 1, the scaffold base 2 is placed on the pit surface (floor surface) 3 of the hoistway. The operator performs maintenance and inspection work on the control panel 1 while riding on the upper surface of the scaffold base 2 placed on the pit surface 3.
　ピット面３から所定の高さだけ上方へ離れた位置には、足場台２に乗った状態で作業者がアクセス可能な高さの限界（即ち、作業者による保守点検作業が可能な高さの限界）を示す作業限界レベルＡが設定されている。この例では、ピット面３上に置かれた足場台２の上面から１８００ｍｍの高さの位置に作業限界レベルＡが設定されている。従って、作業限界レベルＡよりも上方の領域は、作業者がアクセス不可能なアクセス不可領域とされ、作業限界レベルＡよりも下方の領域は、作業者がアクセス可能なアクセス可能領域とされている。 At a position away from the pit surface 3 by a predetermined height, a height limit that is accessible to the worker while riding on the scaffolding platform 2 (that is, a height at which the worker can perform maintenance and inspection work). An operation limit level A indicating (limit) is set. In this example, the work limit level A is set at a position of 1800 mm from the upper surface of the scaffold base 2 placed on the pit surface 3. Accordingly, an area above the work limit level A is an inaccessible area that is not accessible to the worker, and an area below the work limit level A is an accessible area that is accessible to the worker. .
　制御盤１は、一部がアクセス可能領域に配置され、残りの一部がアクセス不可領域に配置された状態で、昇降路内に立てて設置されている。従って、保守点検作業を行う作業者は、制御盤１のうち、アクセス不可領域に配置された部分にアクセスすることができず、アクセス可能領域に配置された部分にのみアクセス可能になっている。 The control panel 1 is installed upright in the hoistway with a part being placed in the accessible area and the remaining part being placed in the inaccessible area. Therefore, the worker who performs the maintenance and inspection work cannot access the portion arranged in the inaccessible area in the control panel 1 and can access only the portion arranged in the accessible area.
　図２は、図１のエレベータの制御盤１を示す正面図である。また、図３は、図２のエレベータの制御盤１を示す一部破断側面図である。図において、制御盤１は、昇降路内に立てて配置された筐体（支持体）４と、筐体４に設けられた回動軸５を中心に回動可能な回動パネル（回動部材）６と、回動パネル６に設けられた保守対象機器７と、回動パネル６から下方へ延びる操作レバー（操作部材）８とを有している。 FIG. 2 is a front view showing the control panel 1 of the elevator shown in FIG. FIG. 3 is a partially broken side view showing the control panel 1 of the elevator shown in FIG. In the figure, a control panel 1 includes a casing (supporting body) 4 arranged upright in a hoistway and a rotating panel (rotating) that can rotate around a rotating shaft 5 provided in the casing 4. Member 6, a maintenance target device 7 provided on the rotation panel 6, and an operation lever (operation member) 8 extending downward from the rotation panel 6.
　筐体４は、一部（上部）がアクセス不可領域に配置され、残りの一部がアクセス可能領域に配置されている。筐体４の正面には、開口部９が設けられている。開口部９は、アクセス不可領域に位置している。この例では、図２に示すように、開口部９の形状が矩形状となっている。 A part (upper part) of the casing 4 is arranged in the inaccessible area, and the remaining part is arranged in the accessible area. An opening 9 is provided on the front surface of the housing 4. The opening 9 is located in the inaccessible area. In this example, as shown in FIG. 2, the shape of the opening 9 is rectangular.
　回動軸５は、開口部９の下縁部に設けられている。また、回動軸５は、筐体４の幅方向に沿って水平に配置されている。この例では、回動軸５が作業限界レベルＡよりも上方に配置されている。 Rotating shaft 5 is provided at the lower edge of opening 9. Further, the rotation shaft 5 is disposed horizontally along the width direction of the housing 4. In this example, the rotation shaft 5 is disposed above the work limit level A.
　回動パネル６は、図３に示すように、回動軸５を中心として回動されることにより、開口部９を塞ぐ閉塞位置（図３の実線）と、閉塞位置よりも下方に位置し、開口部９を開放する開放位置との間で変位される。また、回動パネル６は、保守対象機器７が取り付けられた機器取付板（機器取付部）６ａと、機器取付板６ａの端部から突出し、回動軸５に回動可能に接続された接続板（接続部）６ｂと、機器取付板６ａの両側部から回動軸５に垂直な方向へ突出する一対の側板（突出部）６ｃとを有している。この例では、機器取付板６ａ、接続板６ｂ及び各側板６ｃが一枚の板を曲げて一体に形成されている。 As shown in FIG. 3, the rotation panel 6 is rotated around the rotation shaft 5, thereby being located at a closed position (solid line in FIG. 3) for closing the opening 9 and below the closed position. , And is displaced between the open position where the opening 9 is opened. Moreover, the rotation panel 6 protrudes from the end part of the apparatus attachment plate (apparatus attachment part) 6a to which the maintenance object apparatus 7 is attached, and the apparatus attachment plate 6a, and is connected to the rotation shaft 5 so as to be rotatable. A plate (connecting portion) 6b and a pair of side plates (projecting portions) 6c projecting from both sides of the device mounting plate 6a in a direction perpendicular to the rotation shaft 5 are provided. In this example, the device mounting plate 6a, the connection plate 6b, and each side plate 6c are integrally formed by bending a single plate.
　接続板６ｂは、機器取付板６ａを含む平面に交差する方向へ機器取付板６ａの端部から突出している。この例では、接続板６ｂが機器取付板６ａに対して垂直になっている。 The connection plate 6b protrudes from the end of the device mounting plate 6a in a direction intersecting the plane including the device mounting plate 6a. In this example, the connection plate 6b is perpendicular to the device mounting plate 6a.
　機器取付板６ａは、回動パネル６が閉塞位置にあるときに、回動軸５よりも筐体４の内側に配置される。回動パネル６は、機器取付板６ａと回動軸５との距離が接続板６ｂにより一定に保たれながら、回動軸５を中心に回動される。これにより、回動パネル６が閉塞位置と開放位置との間を変位されるときには、筐体４に対する機器取付板６ａの干渉が回避される。 The device mounting plate 6a is disposed inside the housing 4 relative to the rotating shaft 5 when the rotating panel 6 is in the closed position. The rotating panel 6 is rotated around the rotating shaft 5 while the distance between the device mounting plate 6a and the rotating shaft 5 is kept constant by the connecting plate 6b. Thereby, when the rotation panel 6 is displaced between the closed position and the open position, the interference of the device mounting plate 6a with the housing 4 is avoided.
　各側板６ｃは、回動パネル６が閉塞位置にあるときに、筐体４の背面に向かって機器取付板６ａから突出している。各側板６ｃのうち、いずれか一方には、回動軸５に平行なピン１０が固定されている。ピン１０は、回動パネル６の外側へ側板６ｃから突出している。 Each side plate 6c protrudes from the device mounting plate 6a toward the back surface of the housing 4 when the rotating panel 6 is in the closed position. A pin 10 parallel to the rotation shaft 5 is fixed to one of the side plates 6c. The pin 10 protrudes from the side plate 6 c to the outside of the rotating panel 6.
　保守対象機器７は、保守点検の対象となる機器である。即ち、保守対象機器７は、エレベータの製品寿命よりも寿命の短い機器で、保守点検時に確認、操作、調整又は整備等が必要な機器である。保守対象機器７としては、例えば半導体を搭載したインバータ（電子部品搭載機器）等が挙げられる。なお、筐体４内には、保守対象機器７の他に、複数の機器が収容されている。 The maintenance target device 7 is a device subject to maintenance inspection. That is, the maintenance target device 7 is a device having a life shorter than the product life of the elevator and needs to be confirmed, operated, adjusted, or maintained at the time of maintenance inspection. Examples of the maintenance target device 7 include an inverter (electronic component mounting device) on which a semiconductor is mounted. In addition to the maintenance target device 7, a plurality of devices are accommodated in the housing 4.
　保守対象機器７は、各側板６ｃ間に配置された状態で機器取付板６ａに取り付けられている。また、保守対象機器７は、回動パネル６と一体に変位される。保守対象機器７は、回動パネル６の回動軸５を中心とした回動により、回動軸５よりも上方に位置する通常位置（図３の実線）と、回動軸５よりも下方に位置する点検位置との間で筐体４に対して変位される。即ち、保守対象機器７は、回動パネル６が閉塞位置へ変位されることにより通常位置へ変位され、回動パネル６が開放位置へ変位されることにより点検位置へ変位される。 The maintenance target device 7 is attached to the device mounting plate 6a in a state of being arranged between the side plates 6c. In addition, the maintenance target device 7 is displaced integrally with the rotating panel 6. The maintenance target device 7 has a normal position (solid line in FIG. 3) positioned above the rotation shaft 5 and a position below the rotation shaft 5 by rotation about the rotation shaft 5 of the rotation panel 6. It is displaced with respect to the housing | casing 4 between the inspection positions located in. That is, the maintenance target device 7 is displaced to the normal position when the rotating panel 6 is displaced to the closed position, and is displaced to the inspection position when the rotating panel 6 is displaced to the open position.
　保守対象機器７は、通常位置に達することによりアクセス不可領域に配置され、点検位置に達することによりアクセス可能領域に配置される。また、保守対象機器７は、通常位置にあるときに筐体４内に収容され、点検位置にあるときに筐体４外に露出される。保守対象機器７に対する保守点検作業は、保守対象機器７が通常位置から点検位置へ変位されることにより可能になる。なお、保守対象機器７には、電源線や信号線等の配線が接続されている。保守対象機器７に接続された配線は、保守対象機器７の変位に伴って曲げ可能になっている。 The maintenance target device 7 is arranged in the inaccessible area when it reaches the normal position, and is arranged in the accessible area when it reaches the inspection position. The maintenance target device 7 is accommodated in the housing 4 when in the normal position, and is exposed outside the housing 4 when in the inspection position. Maintenance and inspection work for the maintenance target device 7 is enabled by the maintenance target device 7 being displaced from the normal position to the inspection position. The maintenance target device 7 is connected to wiring such as a power supply line and a signal line. The wiring connected to the maintenance target device 7 can be bent as the maintenance target device 7 is displaced.
　操作レバー８は、ピン１０に変位可能に取り付けられたレバー取付部８ａと、レバー取付部８ａに固定され、所定の長さを持つ操作棒８ｂとを有している。 The operating lever 8 has a lever mounting portion 8a that is detachably mounted on the pin 10, and an operating rod 8b that is fixed to the lever mounting portion 8a and has a predetermined length.
　レバー取付部８ａには、図３に示すように、操作棒８ｂに沿った長穴１１が設けられている。長穴１１には、ピン１０が挿入されている。操作レバー８は、長穴１１にピン１０が挿入された状態でピン１０に保持されている。ピン１０は、長穴１１内を長穴１１の長径方向に沿って変位可能になっている。従って、操作レバー８は、ピン１０が長穴１１内を変位される範囲内でピン１０に対して変位可能になっている。レバー取付部８ａには、操作棒８ｂの上端部が固定されている。操作棒８ｂの下端部は、アクセス可能領域に達している。 As shown in FIG. 3, the lever mounting portion 8a is provided with a long hole 11 along the operation rod 8b. A pin 10 is inserted into the long hole 11. The operation lever 8 is held by the pin 10 in a state where the pin 10 is inserted into the elongated hole 11. The pin 10 can be displaced in the elongated hole 11 along the major axis direction of the elongated hole 11. Therefore, the operation lever 8 can be displaced with respect to the pin 10 within a range in which the pin 10 is displaced in the elongated hole 11. The upper end portion of the operation rod 8b is fixed to the lever mounting portion 8a. The lower end portion of the operation rod 8b reaches the accessible area.
　筐体４の上端部には、保守対象機器７を通常位置に保持するためのフック１２が設けられている。フック１２は、開口部９の上方で筐体４の正面から水平に突出する板状の水平固定部１２ａと、水平固定部１２ａの先端部から下方へ突出する板状の係合部１２ｂとを有している。フック１２は、回動パネル６及び保守対象機器７が筐体４に対して変位される範囲を避けて配置されている。 A hook 12 for holding the maintenance target device 7 in a normal position is provided at the upper end of the housing 4. The hook 12 includes a plate-like horizontal fixing portion 12a that protrudes horizontally from the front of the housing 4 above the opening 9, and a plate-like engagement portion 12b that protrudes downward from the tip of the horizontal fixing portion 12a. Have. The hook 12 is disposed so as to avoid a range in which the rotating panel 6 and the maintenance target device 7 are displaced with respect to the housing 4.
　図４は、図２のエレベータの制御盤１の要部を示す正面図である。また、図５は図４の操作レバー８が係合位置にあるときの制御盤１の要部を示す側面図、図６は図４の操作レバー８が解除位置にあるときの制御盤１の要部を示す側面図である。図において、操作レバー８は、回動パネル６が閉塞位置にあるときに（即ち、保守対象機器７が通常位置にあるときに）、フック１２に係合する係合位置（図５）と、フック１２との係合が外れる解除位置（図６）との間で回動パネル６に対して変位される。解除位置は、係合位置よりも下方の位置とされている。通常位置と点検位置との間での操作レバー８の変位は、ピン１０に対するレバー取付部８ａの変位により行われる。 FIG. 4 is a front view showing a main part of the control panel 1 of the elevator shown in FIG. 5 is a side view showing the main part of the control panel 1 when the operation lever 8 of FIG. 4 is in the engaged position. FIG. 6 is a side view of the control panel 1 when the operation lever 8 of FIG. 4 is in the release position. It is a side view which shows the principal part. In the figure, the operation lever 8 is engaged with the hook 12 (FIG. 5) when the rotary panel 6 is in the closed position (that is, when the maintenance target device 7 is in the normal position). It is displaced with respect to the rotating panel 6 between the release position (FIG. 6) where the engagement with the hook 12 is released. The release position is a position below the engagement position. The displacement of the operating lever 8 between the normal position and the inspection position is performed by the displacement of the lever mounting portion 8a with respect to the pin 10.
　閉塞位置にあるときの回動パネル６は、操作レバー８が係合位置に変位されて操作レバー８とフック１２とが係合されることにより、開放位置への回動が阻止される。即ち、保守対象機器７は、操作レバー８がフック１２に係合されることにより、通常位置に保持される。また、閉塞位置にあるときの回動パネル６は、操作レバー８が解除位置に変位されて操作レバー８とフック１２との係合が外れることにより、開放位置へ回動可能になる。即ち、保守対象機器７は、操作レバー８とフック１２との係合が外れることにより、通常位置から点検位置へ変位可能になる。 When the operation panel 8 is in the closed position, the operation lever 8 is displaced to the engagement position, and the operation lever 8 and the hook 12 are engaged. That is, the maintenance target device 7 is held at the normal position by the operation lever 8 being engaged with the hook 12. Further, when the operation lever 8 is displaced to the release position and the operation lever 8 and the hook 12 are disengaged, the rotation panel 6 in the closed position can be rotated to the open position. That is, the maintenance target device 7 can be displaced from the normal position to the inspection position when the operation lever 8 and the hook 12 are disengaged.
　筐体４の外側面には、操作レバー８を係合位置に保持する保持用ねじ（保持装置）１３が設けられる。保持用ねじ１３としては、例えば手でつまみながら回すことができるつまみねじ等が用いられている。保持用ねじ１３が設けられる位置は、アクセス可能領域とされている。操作レバー８（操作棒８ｂ）の下端部には、図６に示すように、保持用ねじ１３が通されるねじ通し穴１４が設けられている。操作レバー８は、ねじ通し穴１４に通された保持用ねじ１３が筐体４の外側面に設けられたねじ穴（図示せず）に螺合されることにより、係合位置に保持される。 A holding screw (holding device) 13 that holds the operation lever 8 in the engaged position is provided on the outer surface of the housing 4. As the holding screw 13, for example, a thumbscrew that can be turned while being held by hand is used. The position where the holding screw 13 is provided is an accessible area. As shown in FIG. 6, a screw through hole 14 through which the holding screw 13 is passed is provided at the lower end portion of the operation lever 8 (operation rod 8b). The operating lever 8 is held at the engagement position by screwing a holding screw 13 passed through the screw through hole 14 into a screw hole (not shown) provided on the outer surface of the housing 4. .
　操作レバー８は、保持用ねじ１３による保持が解除された状態で外部からの引き下げ力を受けることにより、解除位置に変位されるとともに、閉塞位置から開放位置（即ち、保守対象機器７が通常位置から点検位置へ変位する方向）へ回動パネル６を回動させる。 The operation lever 8 is displaced from the closed position to the open position (that is, the maintenance target device 7 is in the normal position) by receiving a pulling force from outside in a state where the holding by the holding screw 13 is released. The rotating panel 6 is rotated in the direction of displacement from the position to the inspection position.
　次に、制御盤１に搭載された保守対象機器７の保守点検作業を行うときの手順について説明する。保守点検作業が行われない通常運転時には、回動パネル６が閉塞位置に変位されていて、保守対象機器７が筐体４内に収容されている。また、通常運転時には、回動パネル６が開放位置に変位されないように、操作レバー８とフック１２とが互いに係合された状態で操作レバー８が保持用ねじ１３により筐体４に保持されている。このときには、保守対象機器７は、作業者の届かないアクセス不可領域に配置されている。 Next, the procedure for performing maintenance inspection work on the maintenance target device 7 mounted on the control panel 1 will be described. During normal operation in which maintenance inspection work is not performed, the rotary panel 6 is displaced to the closed position, and the maintenance target device 7 is accommodated in the housing 4. Further, during normal operation, the operation lever 8 is held by the housing 4 by the holding screw 13 in a state where the operation lever 8 and the hook 12 are engaged with each other so that the rotating panel 6 is not displaced to the open position. Yes. At this time, the maintenance target device 7 is arranged in an inaccessible area that the worker does not reach.
　保守対象機器７の保守点検時には、まずピット面３に足場台２が置かれる。この後、作業者が足場台２に乗って保持用ねじ１３を筐体４から外す。これにより、操作レバー８が自重で下方へ変位され、操作レバー８とフック１２との係合が外れる。 At the time of maintenance inspection of the maintenance target device 7, the scaffold base 2 is first placed on the pit surface 3. Thereafter, the operator gets on the scaffold 2 and removes the holding screw 13 from the housing 4. As a result, the operation lever 8 is displaced downward by its own weight, and the engagement between the operation lever 8 and the hook 12 is released.
　この後、作業者が操作レバー８を引き下げながら、回動軸５を中心に回動パネル６を回動させる。これにより、保守対象機器７は、通常位置から点検位置へ変位され、アクセス可能領域に達する。 Thereafter, the operator rotates the rotating panel 6 around the rotating shaft 5 while pulling down the operation lever 8. As a result, the maintenance target device 7 is displaced from the normal position to the inspection position and reaches the accessible area.
　この後、作業者が保守対象機器７に対して保守点検を行う。この後、上記と逆の手順により、回動パネル６を閉塞位置に戻し、保持用ねじ１３で操作レバー８を筐体４に留める。これにより、保守対象機器７の保守点検作業が終了する。 After this, the operator performs maintenance and inspection on the maintenance target device 7. Thereafter, the rotating panel 6 is returned to the closed position by a procedure reverse to the above, and the operation lever 8 is fastened to the housing 4 with the holding screws 13. Thereby, the maintenance inspection work of the maintenance target device 7 is completed.
　このようなエレベータの制御盤１では、筐体４に設けられた回動軸５を中心に回動可能な回動パネル６に保守対象機器７が設けられ、回動パネル６の回動により、回動軸５よりも上方に位置する通常位置と、回動軸５よりも下方に位置する点検位置との間で保守対象機器７が変位されるので、通常運転時には、作業者の届かないアクセス不可領域に保守対象機器７を配置しておき、保守点検時にのみ、作業者による保守点検が可能なアクセス可能領域へ保守対象機器７を変位させることができる。これにより、制御盤１の設置スペースを水平方向について広げずに、保守対象機器７のレイアウトの自由度を向上させることができる。 In such an elevator control panel 1, a maintenance target device 7 is provided on a rotation panel 6 that can be rotated around a rotation shaft 5 provided in a housing 4. Since the maintenance target device 7 is displaced between the normal position located above the rotation shaft 5 and the inspection position located below the rotation shaft 5, the access that the operator cannot reach during normal operation is performed. The maintenance target device 7 can be arranged in the unusable area, and the maintenance target apparatus 7 can be displaced to an accessible area where maintenance inspection can be performed by an operator only during maintenance inspection. Thereby, the freedom degree of the layout of the maintenance object apparatus 7 can be improved, without expanding the installation space of the control panel 1 about a horizontal direction.
　また、回動パネル６から下方へ延びる操作レバー８は、保守対象機器７が通常位置にあるときに、フック１２に係合する係合位置と、フック１２との係合が外れる解除位置との間で回動パネル６に対して変位可能になっているので、回動パネル６を回動させるための手段と、保守対象機器７を通常位置に保持する手段とを操作レバー８で兼用することができる。従って、部品点数を少なくすることができ、コストの低減を図ることができる。 Further, the operation lever 8 extending downward from the rotating panel 6 has an engagement position that engages with the hook 12 and a release position that disengages the hook 12 when the maintenance target device 7 is in the normal position. Since it can be displaced with respect to the rotating panel 6 between, the means for rotating the rotating panel 6 and the means for holding the maintenance target device 7 in the normal position are combined with the operation lever 8. Can do. Therefore, the number of parts can be reduced and the cost can be reduced.
　また、回動パネル６は、保守対象機器７が取り付けられる機器取付板６ａを有しており、機器取付板６ａは、保守対象機器７が通常位置にあるときに回動軸５よりも筐体４の内側に配置されるので、機器取付板６ａと回動軸５との距離を一定に保ちながら、回動パネル６を閉塞位置と開放位置との間で変位させることができる。これにより、回動パネル６が変位されるときの筐体４に対する機器取付板６ａの干渉を避けることができる。従って、保守対象機器７の保守点検作業をさらに容易に行うことができる。 The rotating panel 6 has a device mounting plate 6a to which the maintenance target device 7 is mounted. The device mounting plate 6a is more housing than the rotating shaft 5 when the maintenance target device 7 is in the normal position. 4, the rotating panel 6 can be displaced between the closed position and the opened position while keeping the distance between the device mounting plate 6 a and the rotating shaft 5 constant. Thereby, interference of the apparatus mounting plate 6a with respect to the housing | casing 4 when the rotation panel 6 is displaced can be avoided. Therefore, the maintenance and inspection work for the maintenance target device 7 can be performed more easily.
　なお、上記の例では、操作レバー８を係合位置に保持する保持装置が保持用ねじ１３とされているが、これに限定されない。例えば、筐体４に対して操作レバー８の操作棒８ｂを押さえる板ばねを保持装置として筐体４に設けて、筐体４と板ばねとの間で操作棒８ｂを把持することにより、操作レバー８を係合位置に保持するようにしてもよい。また、操作棒８ｂに設けられた切欠部に嵌る突起を保持装置として筐体４に設けて、操作棒８ｂの切欠部を突起に嵌めることにより操作レバー８を係合位置に保持するようにしてもよい。 In the above example, the holding device that holds the operation lever 8 in the engaged position is the holding screw 13, but is not limited thereto. For example, a leaf spring that holds the operation rod 8b of the operation lever 8 against the housing 4 is provided in the housing 4 as a holding device, and the operation rod 8b is gripped between the housing 4 and the leaf spring so that the operation can be performed. You may make it hold | maintain the lever 8 in an engagement position. Further, a projection that fits into the notch provided on the operation rod 8b is provided on the housing 4 as a holding device, and the operation lever 8 is held in the engaged position by fitting the notch of the operation rod 8b into the projection. Also good.

FIG. 7 is a front view of an essential part showing a state in which the operating lever 8 and the hook 21 are engaged in the elevator control panel 1 according to the second embodiment of the present invention. FIG. 8 is a side view of an essential part showing the control panel 1 of the elevator shown in FIG. Further, FIG. 9 is a front view of a main part showing a state where the operation lever 8 and the hook 21 are disengaged in the elevator control panel 1 of FIG. 7, and FIG. 10 shows the elevator control panel 1 of FIG. It is a principal part side view shown. Further, FIG. 11 is a front view of a main part showing a state in which the maintenance object device 7 is displaced to the inspection position in the elevator control panel 1 of FIG. 9, and FIG. 12 is a main part showing the elevator control panel 1 of FIG. It is a side view.
　図において、筐体４の正面には、フック２１が設けられている。フック２１は、アクセス不可領域で開口部９に隣接して配置されている。また、フック２１は、筐体４の正面から筐体４外へ水平に突出する受け部２１ａと、受け部２１ａの先端部から上方へ突出する係合部２１ｂとを有している。従って、筐体４と係合部２１ｂとの間には、所定の隙間が形成されている。 In the figure, a hook 21 is provided on the front surface of the housing 4. The hook 21 is disposed adjacent to the opening 9 in the inaccessible area. The hook 21 has a receiving portion 21a that protrudes horizontally from the front of the housing 4 to the outside of the housing 4, and an engaging portion 21b that protrudes upward from the tip of the receiving portion 21a. Accordingly, a predetermined gap is formed between the housing 4 and the engaging portion 21b.
　操作レバー８のレバー取付部８ａには、フック２１が通されるフック通し穴２２が設けられている。フック通し穴２２の大きさは、筐体４を正面から見たときに、フック通し穴２２内に係合部２１ｂの全体が収まる大きさとされている。 The lever mounting portion 8a of the operation lever 8 is provided with a hook through hole 22 through which the hook 21 is passed. The size of the hook through hole 22 is set such that the entire engaging portion 21b fits in the hook through hole 22 when the housing 4 is viewed from the front.
　操作レバー８は、回動パネル６が閉塞位置にあるときに（即ち、保守対象機器７が通常位置にあるときに）、フック２１に係合する係合位置（図７及び図８）と、フック２１との係合が外れる解除位置（図９及び図１０）との間で回動パネル６に対して変位可能になっている。係合位置は、解除位置よりも下方に位置している。 The operation lever 8 is engaged with the hook 21 when the rotary panel 6 is in the closed position (that is, when the maintenance target device 7 is in the normal position) (FIGS. 7 and 8), It can be displaced with respect to the rotating panel 6 between the release position (FIGS. 9 and 10) where the engagement with the hook 21 is disengaged. The engagement position is located below the release position.
　操作レバー８が解除位置にあるときには、筐体４を正面から見ると、フック通し穴２２内にフック２１の全体が収まっている。操作レバー８が係合位置にあるときには、筐体４を正面から見ると、フック通し穴２２がフック２１に対して下方へずれている。 When the operation lever 8 is in the release position, the entire hook 21 is accommodated in the hook through hole 22 when the housing 4 is viewed from the front. When the operation lever 8 is in the engaged position, the hook through hole 22 is shifted downward with respect to the hook 21 when the housing 4 is viewed from the front.
　操作レバー８がフック２１に係合されている状態では、回動パネル６が閉塞位置に保持され、保守対象機器７が通常位置に保持される。操作レバー８とフック２１との係合が外れることにより、回動パネル６が閉塞位置から開放位置へ変位可能になり、保守対象機器７が通常位置から点検位置へ変位可能になる。 When the operation lever 8 is engaged with the hook 21, the rotary panel 6 is held at the closed position, and the maintenance target device 7 is held at the normal position. By disengaging the operation lever 8 and the hook 21, the rotation panel 6 can be displaced from the closed position to the open position, and the maintenance target device 7 can be displaced from the normal position to the inspection position.
　なお、この例では、実施の形態１の保持用ねじ１３は設けられていない。他の構成は実施の形態１と同様である。 In this example, the holding screw 13 of the first embodiment is not provided. Other configurations are the same as those in the first embodiment.
　保守対象機器７の保守点検作業を行うときの手順については、操作レバー８とフック２１との係合を外す手順と、操作レバー８をフック２１に係合させる手順とを除き、実施の形態１と同様である。 The procedure for performing maintenance and inspection work on the maintenance target device 7 is the same as in the first embodiment except for the procedure for disengaging the operation lever 8 and the hook 21 and the procedure for engaging the operation lever 8 with the hook 21. It is the same.
　操作レバー８とフック２１との係合を外すときには、まず操作棒８ｂを上方へ押し上げて操作レバー８を係合位置から解除位置へ変位させる。この後、操作レバー８を筐体４の正面から手前に引きながら、回動パネル６を回動させる。これにより、係合部２２ｂがフック通し穴２２を通過し、回動パネル６が開放位置へ変位される。 When disengaging the operation lever 8 and the hook 21, the operation rod 8b is first pushed upward to displace the operation lever 8 from the engagement position to the release position. Thereafter, the pulling panel 6 is rotated while pulling the operation lever 8 forward from the front of the housing 4. Thereby, the engaging part 22b passes the hook through-hole 22, and the rotation panel 6 is displaced to an open position.
　操作レバー８をフック２１に係合させるときには、まず操作レバー８を解除位置に変位させた状態で、回動パネル６を開放位置から閉塞位置へ変位させる。このとき、係合部２２ｂがフック通し穴２２を通過する。回動パネル６が閉塞位置に達した後、操作棒８ｂを引き下げて、操作レバー８を解除位置から係合位置へ変位させる。これにより、操作レバー８がフック２１に掛けられた状態で、操作レバー８とフック２１とが互いに係合される。 When engaging the operating lever 8 with the hook 21, the rotating panel 6 is first displaced from the open position to the closed position with the operating lever 8 being displaced to the release position. At this time, the engaging portion 22 b passes through the hook through hole 22. After the rotation panel 6 reaches the closed position, the operation rod 8b is pulled down to displace the operation lever 8 from the release position to the engagement position. Thereby, the operating lever 8 and the hook 21 are engaged with each other in a state where the operating lever 8 is hooked on the hook 21.
　このようなエレベータの制御盤１でも、操作レバー８が、フック２１に係合する係合位置と、フック２１との係合が外れる解除位置との間で回動パネル６に対して変位可能になっているので、回動パネル６を回動させるための手段と、保守対象機器７を通常位置に保持する手段とを操作レバー８で兼用することができる。従って、部品点数を少なくすることができ、コストの低減を図ることができる。 Even in the control panel 1 of such an elevator, the operation lever 8 can be displaced with respect to the rotating panel 6 between an engagement position where the operation lever 8 is engaged with the hook 21 and a release position where the engagement with the hook 21 is released. Therefore, the operation lever 8 can also be used as the means for rotating the rotation panel 6 and the means for holding the maintenance target device 7 in the normal position. Therefore, the number of parts can be reduced and the cost can be reduced.
　また、係合部２１ｂを有するフック２１が筐体４に設けられ、フック２１が通されるフック通し穴２２が操作レバー８に設けられているので、操作レバー８をフック２１に掛けることにより操作レバー８を係合位置に保持することができる。これにより、操作レバー８を係合位置に保持するための専用の保持装置を筐体４に設ける必要がなくなり、部品点数をさらに少なくすることができ、コストの低減をさらに図ることができる。 In addition, the hook 21 having the engaging portion 21 b is provided in the housing 4, and the hook through hole 22 through which the hook 21 is passed is provided in the operation lever 8, so that the operation can be performed by hooking the operation lever 8 on the hook 21. The lever 8 can be held in the engaged position. Thereby, it is not necessary to provide the housing 4 with a dedicated holding device for holding the operation lever 8 in the engaged position, the number of parts can be further reduced, and the cost can be further reduced.

　図において、保守対象機器７は、回動軸５から所定の距離だけ離して回動パネル６に取り付けられている。筐体４内には、保守対象機器７と異なる保守非対象機器３１が収容されている。保守非対象機器３１は、筐体４に取り付けられている。また、保守非対象機器３１は、アクセス不可領域に配置されている。さらに、保守非対象機器３１の一部は、通常位置にあるときの保守対象機器７と回動軸５との間の高さに配置されている。従って、保守非対象機器３１は、保守対象機器７の通常位置の高さよりも下方に配置されている。 In the figure, the maintenance target device 7 is attached to the rotating panel 6 at a predetermined distance from the rotating shaft 5. A maintenance non-target device 31 different from the maintenance target device 7 is accommodated in the housing 4. The maintenance non-target device 31 is attached to the housing 4. The maintenance non-target device 31 is arranged in the inaccessible area. Further, a part of the maintenance non-target device 31 is disposed at a height between the maintenance target device 7 and the rotating shaft 5 when in the normal position. Accordingly, the maintenance non-target device 31 is arranged below the height of the normal position of the maintenance target device 7.
　保守非対象機器３１は、保守点検の対象から除外されている機器である。即ち、保守非対象機器３１は、エレベータの製品寿命よりも寿命の長い機器で、交換作業や配線の取り付け部分の増し締め作業を必要としない機器である。保守非対象機器３１としては、例えばトランスやリアクトル、抵抗等が挙げられる。 The maintenance non-target device 31 is a device that is excluded from the maintenance inspection target. That is, the maintenance non-target device 31 is a device that has a longer life than the product life of the elevator, and does not require replacement work or retightening work of the wiring attachment portion. Examples of the maintenance non-target device 31 include a transformer, a reactor, and a resistor.
　他の構成は実施の形態１と同様である。また、保守対象機器７の保守点検作業を行うときの手順も実施の形態１と同様である。 Other configurations are the same as those in the first embodiment. Further, the procedure for performing the maintenance inspection work on the maintenance target device 7 is the same as that in the first embodiment.
　このようなエレベータの制御盤１では、保守対象機器７が通常位置にあるときに保守対象機器７の下方に配置される保守非対象機器３１が筐体４に設けられているので、保守点検の対象となっている保守対象機器７だけでなく、保守点検の対象から除外されている保守非対象機器３１も、アクセス不可領域に配置することができ、アクセス不可領域をさらに有効に活用することができる。 In such an elevator control panel 1, the maintenance non-target device 31 arranged below the maintenance target device 7 is provided in the casing 4 when the maintenance target device 7 is in the normal position. Not only the target maintenance target device 7 but also the maintenance non-target device 31 excluded from the maintenance inspection target can be arranged in the inaccessible area, and the inaccessible area can be used more effectively. it can.
　なお、上記の例では、通常位置にあるときの保守対象機器７と回動軸５との間の高さに保守非対象機器３１の一部が配置されているが、通常位置にあるときの保守対象機器７と回動軸５との間の高さに保守非対象機器３１の全部が配置されていてもよい。 In the above example, a part of the maintenance non-target device 31 is arranged at a height between the maintenance target device 7 and the rotation shaft 5 at the normal position. All of the maintenance non-target devices 31 may be arranged at a height between the maintenance target device 7 and the rotation shaft 5.
　また、上記の例では、保守対象機器７の通常位置の高さよりも下方に保守非対象機器３１が配置されているが、保守対象機器７の通常位置の高さよりも上方に保守非対象機器３１を配置してもよい。 Further, in the above example, the maintenance non-target device 31 is disposed below the normal position height of the maintenance target device 7, but the maintenance non-target device 31 is higher than the normal position height of the maintenance target device 7. May be arranged.
　また、上記の例では、保守対象機器７を通常位置に保持する手段として、実施の形態１の操作レバー８及びフック１２が用いられているが、実施の形態２の操作レバー８及びフック２１を、保守対象機器７を通常位置に保持する手段として用いてもよい。 In the above example, the operation lever 8 and the hook 12 of the first embodiment are used as means for holding the maintenance target device 7 in the normal position, but the operation lever 8 and the hook 21 of the second embodiment are used. The maintenance target device 7 may be used as means for holding the maintenance target device 7 at the normal position.
　また、各上記実施の形態では、操作レバー８が係合位置に変位されて操作レバー８とフック１２，２１とが係合されることにより、保守対象機器７が通常位置に保持されるようになっているが、保守対象機器７を通常位置に保持させることができるのであれば、フック１２，２１はなくてもよい。例えば、保守対象機器７が通常位置へ変位される方向へ回動パネル６を付勢する付勢体（例えば、捻りばね等）を回動軸５に設けることにより、保守対象機器７を通常位置に保持させるようにしてもよい。この場合、操作レバー８は回動パネル６に対して係合位置と解除位置との間で変位される必要はなく、操作レバー８がピン１０を中心に回動可能になっていればよい。保守対象機器７が通常位置から点検位置へ変位されるときには、付勢体の付勢力に逆らって回動パネル６が閉塞位置から開放位置へ変位される。 Further, in each of the above embodiments, the operation lever 8 is displaced to the engagement position and the operation lever 8 and the hooks 12 and 21 are engaged, so that the maintenance target device 7 is held at the normal position. However, the hooks 12 and 21 may not be provided as long as the maintenance target device 7 can be held in the normal position. For example, by providing an urging body (for example, a torsion spring) that urges the rotation panel 6 in a direction in which the maintenance target device 7 is displaced to the normal position, the maintenance target device 7 is moved to the normal position. You may make it hold | maintain. In this case, the operation lever 8 does not need to be displaced between the engagement position and the release position with respect to the rotation panel 6, and the operation lever 8 only needs to be rotatable about the pin 10. When the maintenance target device 7 is displaced from the normal position to the inspection position, the rotating panel 6 is displaced from the closed position to the open position against the urging force of the urging body.
　また、保守対象機器７が通常位置へ変位される方向へ回動パネル６を付勢する付勢体を回動軸５に設けた場合、回動パネル６から下方へ延びる操作部材を、操作レバー８ではなく、例えばロープ、ベルト又はチェーン等、曲げ可能な連続体としてもよい。 In addition, when the urging body that urges the rotation panel 6 in the direction in which the maintenance target device 7 is displaced to the normal position is provided on the rotation shaft 5, an operation member extending downward from the rotation panel 6 is provided with an operation lever Instead of 8, it may be a bendable continuous body such as a rope, belt or chain.

However, the rotation shaft 5 is disposed at the same height as the work limit level A or below the work limit level A. You may arrange.
　また、各上記実施の形態では、回動パネル６の各側板６ｃのうち、一方のみにピン１０を介して操作レバー８が取り付けられているが、各側板６ｃの両方にピン１０を介して操作レバー８を取り付けてもよい。この場合、各操作レバー８は、回動パネル６に対して別個独立に変位されるようにしてもよいし、各操作レバー８を連結する連結部材を各操作レバー８の上端部間に固定することにより回動パネル６に対して一体となって変位されるようにしてもよい。 Moreover, in each said embodiment, although the operation lever 8 is attached via the pin 10 to only one among each side plate 6c of the rotation panel 6, it operates via the pin 10 to both each side plate 6c. The lever 8 may be attached. In this case, each operation lever 8 may be displaced independently with respect to the rotation panel 6, and a connecting member that connects each operation lever 8 is fixed between the upper end portions of each operation lever 8. By doing so, it may be displaced integrally with the rotating panel 6.
