Description

本発明は安全帯の連結部を連結可能な支持部材を備えたエレベータ装置に関する。   The present invention relates to an elevator apparatus including a support member capable of connecting a connecting portion of a safety belt.

エレベータ装置のかご上で保守・点検作業を行う際には安全帯を着用することが義務付けられており、従来では例えばかごの天面部上に立設した手摺りを安全帯の連結部(ランヤードのフック部等)を連結する支持部材として用いていた(例えば、特許文献1参照)。   When performing maintenance / inspection work on the elevator car, it is mandatory to wear a safety belt. Conventionally, for example, a handrail erected on the top surface of the car is connected to the safety belt connecting part (the lanyard). It has been used as a support member for connecting a hook portion or the like (see, for example, Patent Document 1).

ところでかごをパネルで形成したようなエレベータ装置にあってはかごの天井パネルで形成された天面部自体の強度が弱く、このため上記支持部材としての手摺りをかご上に設置するには特別な部材を設けてかごの天面部の強度を強くする必要がある。しかし、かごの天面部の強度を強くする特別な部材を設けるにはコストがかかり、またエレベータ装置の設置作業に手間がかかる。またかごの天面部上には手摺りを立設していないものもあり、このものにあってはかごの天面部上に安全帯の連結部が連結可能な支持部材を新たに設ける必要があるのだが、この場合も同様にかごに天面部の強度を強くする特別な部材を設ける必要がある。また上記支持部材はかごに強固に固着する必要があり、この点でもコストがかかり、エレベータの設置作業に手間がかかる。
特開平8−198549号公報
By the way, in an elevator apparatus in which a car is formed of a panel, the strength of the top surface part itself formed by the ceiling panel of the car is weak, so that a handrail as the support member is specially installed on the car. It is necessary to increase the strength of the top surface of the car by providing a member. However, it is costly to provide a special member that increases the strength of the top surface of the car, and it takes time to install the elevator apparatus. In addition, there is a handrail that does not stand upright on the top surface portion of the car, and in this case, it is necessary to newly provide a support member to which the connecting portion of the safety belt can be connected on the top surface portion of the car. However, in this case as well, it is necessary to provide a special member for increasing the strength of the top surface portion in the car as well. Further, the support member needs to be firmly fixed to the car, which is also expensive in this respect and takes time to install the elevator.
JP-A-8-198549

本発明は上記従来の問題点に鑑みて発明したものであって、かごの天面部の強度を強くする特別な部材を設けることなく安全帯の連結部が連結される支持部材を強固に取付けることができ、コストの削減及び設置作業の容易化を実現できるエレベータ装置を提供することを課題とするものである。   The present invention has been invented in view of the above-mentioned conventional problems, and firmly attaches a support member to which a connecting portion of a safety belt is connected without providing a special member that increases the strength of the top surface portion of the car. Therefore, it is an object of the present invention to provide an elevator apparatus that can realize cost reduction and easy installation work.

上記課題を解決するために本発明に係るエレベータ装置は、プラットホーム16の側端部に立設される縦枠部17の上横枠体20に昇降路2に立設した油圧ジャッキ7のロッド9の上端部を固着し、油圧ジャッキ7を駆動することで昇降路2においてプラットホーム16及び該プラットホーム16に載設したかご1を昇降する油圧式のエレベータ装置において、安全帯の連結部を連結可能な支持部材24を上横枠体20に設けて成ることを特徴とする。油圧ジャッキ7のロッド9の上端部が固着される構造上強度の強い上横枠体20に支持部材24を設けることで、かご1の天面部の強度を高めるための特別な部材を設けることなく安全帯の連結部が連結される支持部材24を強固に取付けることができ、これによりコストを削減でき、またエレベータ装置の設置作業の手間を省ける。   In order to solve the above-described problems, an elevator apparatus according to the present invention includes a rod 9 of a hydraulic jack 7 erected on a hoistway 2 on an upper horizontal frame 20 of a vertical frame 17 erected on a side end of a platform 16. In the hydraulic elevator device that lifts and lowers the platform 16 and the car 1 mounted on the platform 16 in the hoistway 2 by driving the hydraulic jack 7 by fixing the upper end portion of the vehicle, the connecting portion of the safety belt can be connected. The support member 24 is provided on the upper horizontal frame body 20. Without providing a special member for increasing the strength of the top surface portion of the car 1 by providing the support member 24 on the upper horizontal frame body 20 having a high structural strength to which the upper end portion of the rod 9 of the hydraulic jack 7 is fixed. The support member 24 to which the connecting portion of the safety belt is connected can be firmly attached, whereby the cost can be reduced and the labor for installing the elevator apparatus can be saved.

また支持部材24の一端部に安全帯の連結部を連結可能な取付部25を形成し、平面視で支持部材24の全部が上横枠体20に重複した状態と取付部25が上横枠体20よりも外側に位置する状態とに変更可能となるように、支持部材24の取付部25とは反対側の他端部を上横枠体20に縦軸回りに回動可能に取付けることも好ましい。支持部材24に安全帯の連結部を連結しない際やエレベータ装置の設置作業の際に、支持部材24を回動して平面視において上横枠体20から外側に突出しない状態に変更することができ、これによりかご1を昇降させた際に昇降路2内に設けた配線等の部材に支持部材24が当たったり、またプラットホーム16にかご1を載設する際に縦枠部17に設けた支持部材24にかご1が当たったり、配線作業等をする際に支持部材24が邪魔になったりすることを防止できる。   Further, an attachment portion 25 capable of connecting a safety belt connecting portion is formed at one end portion of the support member 24, and the attachment portion 25 is in an upper horizontal frame when the support member 24 is entirely overlapped with the upper horizontal frame body 20 in a plan view. The other end portion of the support member 24 opposite to the mounting portion 25 is attached to the upper horizontal frame body 20 so as to be rotatable about the vertical axis so that it can be changed to a state located outside the body 20. Is also preferable. When the connecting portion of the safety belt is not connected to the support member 24 or when the elevator apparatus is installed, the support member 24 is rotated so as not to protrude outward from the upper horizontal frame body 20 in plan view. Thus, when the car 1 is raised and lowered, the support member 24 hits a member such as a wiring provided in the hoistway 2, or when the car 1 is placed on the platform 16, it is provided in the vertical frame portion 17. It is possible to prevent the car 1 from hitting the support member 24 and preventing the support member 24 from getting in the way when performing wiring work or the like.

また上横枠体20の平面視における中央部に支持部材24の取付部25とは反対側の他端部を載置し、該上横枠体20の長手方向の中央部及び支持部材24の他端部に上方からボルト28を挿通すると共に該ボルト28に支持部材24の他端部を回動可能に取付け、ボルト28の軸部29をロッド9の上端部に螺合して上横枠体20にロッド9の上端を固着することも好ましい。上横枠体20をロッド9の上端部に固着するためのボルト28を用いて支持部材24を上横枠体20に取付けることができ、またこのボルト28を用いて支持部材24を取付部25とは反対側の他端部を平面視で支持部材24の全部が上横枠体20に重複した状態と取付部25が上横枠体20よりも外側に位置する状態とに変更可能となるように上横枠体20に縦軸回りに回動可能に取付けることができる。またボルト28により平面視における上横枠体20の中央部をロッド9の上端部に固着できるので、上横枠体20をロッド9に強固に固着できるのは勿論、加えて支持部材24も上横枠体20の平面視における中央部に取付けられるので、支持部材24を回動させた際には取付部25をかご1の平面視における中央部と上横枠体20の長手方向において同じ箇所に位置させることができ、これによりかご1上のどの場所でも作業ができるように安全帯のロープの長さを設定した場合にロープの長さを短くでき、作業者がロープに足を引掛けて転んだりすることを防止できる。   Further, the other end of the upper horizontal frame 20 opposite to the mounting portion 25 is placed in the center of the upper horizontal frame 20 in plan view, and the central portion of the upper horizontal frame 20 in the longitudinal direction and the support member 24 are arranged. A bolt 28 is inserted into the other end portion from above and the other end portion of the support member 24 is rotatably attached to the bolt 28, and a shaft portion 29 of the bolt 28 is screwed to the upper end portion of the rod 9 to be connected to the upper horizontal frame. It is also preferable to fix the upper end of the rod 9 to the body 20. The support member 24 can be attached to the upper horizontal frame body 20 using a bolt 28 for fixing the upper horizontal frame body 20 to the upper end portion of the rod 9, and the support member 24 is attached to the attachment portion 25 using this bolt 28. It is possible to change the other end portion on the opposite side to a state where the entire support member 24 overlaps the upper horizontal frame body 20 in a plan view and a state where the mounting portion 25 is located outside the upper horizontal frame body 20. Thus, it can be attached to the upper horizontal frame 20 so as to be rotatable around the vertical axis. Further, since the center portion of the upper horizontal frame body 20 in a plan view can be fixed to the upper end portion of the rod 9 by the bolt 28, the upper horizontal frame body 20 can be firmly fixed to the rod 9 and, in addition, the support member 24 can be fixed to the upper portion. Since it is attached to the central portion of the horizontal frame body 20 in plan view, when the support member 24 is rotated, the attachment portion 25 is the same in the longitudinal direction of the upper horizontal frame body 20 and the central portion of the car 1 in plan view. If you set the rope length of the safety belt so that you can work anywhere on the car 1, the rope length can be shortened and the operator can hook the rope Can be prevented from falling.

本発明ではかごの天面部の強度を高めるための特別な部材を設けることなく安全帯の連結部が連結される支持部材を強固に取付けることができ、コストを削減でき、エレベータ装置の設置作業の手間を省ける。   In the present invention, it is possible to firmly attach the support member to which the connecting portion of the safety belt is connected without providing a special member for increasing the strength of the top surface portion of the car, and it is possible to reduce the cost and to install the elevator apparatus. Save time and effort.

A hydraulic jack 7 composed of a lower cylinder 8 and an upper rod 9 extending up and down with respect to the cylinder 8 is provided upright in the center of the jack stand 5 in plan view. A hydraulic unit 11 connected to the cylinder 8 of the hydraulic jack 7 via the hydraulic hose 10 is mounted on the bottom surface of the hoistway 2, and the rod 9 of the hydraulic jack 7 is moved by driving the hydraulic unit 11. It can be expanded and contracted up and down. In addition, long guide rails 12 are vertically provided on both sides of the jack stand 5 so as to face each other, and rail portions 13 are formed on the opposing surface portions of the respective guide rails 12 over substantially the entire length in the longitudinal direction. .

昇降路2内を昇降するかご1は鋼材を枠組みしてなる正面視L字状のかご枠15上に設置されるもので、該かご枠15はかご1が設置されるプラットホーム16と該プラットホーム16の左右方向の側端部に立設する縦枠部17とで構成される。縦枠部17は図4、図5等に示すように前後方向の両側に配した側縦枠体19と、両側の側縦枠体19の上端部間及び下端部間の夫々を連結する上横枠体20及び下横枠体21とで構成されて、矩形状に枠組みされている。   The car 1 that moves up and down in the hoistway 2 is installed on a car frame 15 having an L-shape in front view formed by a steel frame. The car frame 15 is a platform 16 on which the car 1 is installed, and the platform 16. It is comprised with the vertical frame part 17 standingly arranged in the side end part of the left-right direction. As shown in FIGS. 4 and 5, the vertical frame portion 17 connects the side vertical frame body 19 disposed on both sides in the front-rear direction and the upper end portion and the lower end portion of the side vertical frame body 19 on both sides. It is composed of a horizontal frame 20 and a lower horizontal frame 21 and is framed in a rectangular shape.

図4に示す縦枠部17の上端部を構成する上横枠体20は前後に長い下向きコ字状の鋼材からなり、このコ字状の上横枠体20の上面部の中央部(前後方向の中間部で且つ左右方向の中間部)はロッド9の上端面に載置されている。またこの上横枠体20の上面部の中央部にはボルト挿通孔23を穿設している。   The upper horizontal frame 20 constituting the upper end portion of the vertical frame portion 17 shown in FIG. 4 is made of a steel material having a downward U-shape that is long in the front-rear direction. The intermediate portion in the direction and the intermediate portion in the left-right direction) is placed on the upper end surface of the rod 9. A bolt insertion hole 23 is formed in the center of the upper surface of the upper horizontal frame 20.

上横枠体20の上面部の中央部には図1等に示すように平面視長方形で水平板状の支持部材24を縦軸回りに回動自在に取付けている。支持部材24の長手方向の一端部には図示しない安全帯のフック部からなる連結部を係止自在とする取付部25として連結部取付用孔を穿設している。また支持部材24の取付部25とは反対側の他端部にはボルト用孔26を穿設してあり、このボルト用孔26及び上横枠体20のボルト挿通孔23はロッド9の上端面に形成したボルト穴27に連通しており、該ボルト用孔26及びボルト挿通孔23に上方から挿通したボルト28の軸部29をロッド9のボルト穴27の内周面に形成した雌ねじ部に螺合することで、支持部材24のボルト用孔26側の端部及び上横枠体20の上面部がロッド9の上端部に固着されている。このように上横枠体20の上面部にロッド9の上端部を固着することで、前述の油圧ジャッキ7のロッド9を伸縮させた際にはかご枠15及びかご枠15に設置されたかご1を昇降できるようになっている。また上記支持部材24はボルト穴27に対するボルト28の螺合を緩めて上横枠体20に対してボルト28をやや上昇させることで、支持部材24のボルト用孔26に挿通したボルト28の軸部29を回動中心として支持部材24を縦軸回りに回転できるようになっている。   As shown in FIG. 1 and the like, a horizontal plate-like support member 24 having a rectangular shape in plan view is attached to the center of the upper surface of the upper horizontal frame 20 so as to be rotatable about the vertical axis. At one end in the longitudinal direction of the support member 24, a connecting portion mounting hole is drilled as a mounting portion 25 that can lock a connecting portion formed of a hook portion of a safety belt (not shown). A bolt hole 26 is formed in the other end of the support member 24 opposite to the mounting portion 25, and the bolt hole 26 and the bolt insertion hole 23 of the upper horizontal frame body 20 are located above the rod 9. An internal thread portion formed in the inner peripheral surface of the bolt hole 27 of the rod 9 is connected to the bolt hole 27 formed in the end face, and the shaft portion 29 of the bolt 28 inserted through the bolt hole 26 and the bolt insertion hole 23 from above. The end of the support member 24 on the bolt hole 26 side and the upper surface of the upper horizontal frame 20 are fixed to the upper end of the rod 9.

Long holes 46 that are long in the longitudinal direction of the angle 43 are formed on both sides in the longitudinal direction of the vertical piece 45 of the L-shaped angle 43, and bolts 47 are formed in the long holes 46 from the side opposite to the vertical frame 17. The shaft portion is inserted into the upper end portion of the side piece portion 30 on the side of the car 1 of each side vertical frame body 19 of the vertical frame portion 17 and screwed into the car steady block 48. The upper end portion of the frame portion 17 is fixed to the upper end portion of the car 1 to prevent the car 1 from swinging with respect to the vertical frame portion 17. Further, as shown in FIG. 9, a car door opening / closing device 49 is attached to the upper edge of the front opening of the car 1 formed by the left and right side panels 41b and 41c, the ceiling panel 42, and the floor panel 40. The car door 50 that closes the front opening of the car 1 can be automatically opened and closed by the device 49. 2 is a control panel of the elevator apparatus mounted on the ceiling panel 42 of the car 1, and 52 is a lighting fixture (downlight) that illuminates the inside of the car 1.

しかして本例のエレベータ装置にあっては前述の支持部材24を取付部25が平面視で上横枠体20よりも外側に位置させた状態(好ましくは図1に示すように取付部25が平面視で上横枠体20よりもかご1側に位置させた状態)にし、この状態でボルト28により支持部材24を上横枠体20に固定することで、支持部材24の取付部25に作業者が着用した安全帯の連結部を連結して安全を確保しつつかご1上で保守・点検作業を行えるようになっている。またこの支持部材24は特に油圧ジャッキ7のロッド9の上端部が固着される構造上強度の強いかご枠15の上横枠体20に設けられているので、かご1の天面部の強度を高めるための特別な部材を設けることなく支持部材24を強固に取付けることができる。   Therefore, in the elevator apparatus of this example, the above-described support member 24 is in a state where the mounting portion 25 is positioned outside the upper horizontal frame body 20 in plan view (preferably the mounting portion 25 is as shown in FIG. 1). In a state of being positioned on the side of the car 1 with respect to the upper horizontal frame body 20 in plan view), and in this state, the support member 24 is fixed to the upper horizontal frame body 20 with the bolts 28, so that the mounting portion 25 of the support member 24 is fixed. Maintenance / inspection work can be performed on the car 1 while securing the safety by connecting the connecting part of the safety belt worn by the worker. Further, since the support member 24 is provided on the upper horizontal frame 20 of the car frame 15 having a high structural strength to which the upper end portion of the rod 9 of the hydraulic jack 7 is particularly fixed, the strength of the top surface portion of the car 1 is increased. Therefore, the support member 24 can be firmly attached without providing a special member.

また支持部材24に安全帯の連結部を連結しない場合には、支持部材24を回動して平面視で支持部材24の全部が上横枠体20に重複した状態にし、これにより支持部材24を平面視において上横枠体20から外側に突出しない収納状態に変更することができ、これによりかご1を昇降させた際に昇降路2内に設けた配線等の部材に支持部材24が当たることを防止できる。またエレベータ装置の設置作業の際にも上記同様支持部材24を収納状態に変更して仕舞うことができ、これにより正面視L字状のかご枠15のプラットホーム16にかご1を載設する際に支持部材24にかご1が当たったり、配線作業等をする際に支持部材24が邪魔になることを防止でき、支持部材24をエレベータ装置の設置作業に際に支障をきたすことを防止できる。   Further, when the connecting portion of the safety belt is not connected to the support member 24, the support member 24 is rotated so that the entire support member 24 overlaps the upper horizontal frame body 20 in a plan view. Can be changed to a storage state that does not protrude outward from the upper horizontal frame body 20 in plan view, so that when the car 1 is raised or lowered, the support member 24 hits a member such as a wiring provided in the hoistway 2. Can be prevented. In addition, when the elevator apparatus is installed, the support member 24 can be changed to the housed state in the same manner as described above, so that when the car 1 is placed on the platform 16 of the car frame 15 having the L-shape when viewed from the front. It is possible to prevent the car 1 from hitting the support member 24 and to prevent the support member 24 from getting in the way when performing wiring work or the like, and it is possible to prevent the support member 24 from being obstructed during the installation work of the elevator apparatus.

また本例では上横枠体20の平面視における中央部に支持部材24の取付部25とは反対側の他端部を載置し、該上横枠体20の長手方向の中央部及び支持部材24の他端部に上方からボルト28を挿通すると共に該ボルト28に支持部材24の他端部を回動可能に取付け、ボルト28の軸部29をロッド9の上端部に螺合して上横枠体20にロッド9の上端を固着したので、上横枠体20をロッド9の上端部に固着するためのボルト28を用いて支持部材24を上横枠体20に取付けることができる。またこの場合ボルト28のロッド9に対する螺合を緩めることで支持部材24を回動可能として前述の収納状態や使用状態に変更可能とできるため、簡単な構成で支持部材24を収納状態や使用状態に変更可能とすることができる。またボルト28により平面視における上横枠体20の中央部をロッド9の上端部に固着できるので、上横枠体20をロッド9に強固に固着できるのは勿論、加えて支持部材24も上横枠体20の平面視における中央部に取付けられるので、支持部材24を回動させた際には取付部25をかご1の平面視における中央部と前後方向の同じ箇所に位置させることができ、即ち平面視でかご1の上横枠体20とは反対側の2つの角のうち一方の角から取付部25までの距離と他方の角から取付部25までの距離とを略同じとすることができ、これによりかご1上のいずれの場所でも作業ができるように安全帯のロープの長さを設定した場合にこのロープの長さを短くできて、作業者がロープに足を引掛けて転んだりすることを防止できる。   In this example, the other end of the support member 24 opposite to the mounting portion 25 is placed at the center of the upper horizontal frame 20 in plan view, and the longitudinal center of the upper horizontal frame 20 is supported. A bolt 28 is inserted into the other end portion of the member 24 from above, and the other end portion of the support member 24 is rotatably attached to the bolt 28, and a shaft portion 29 of the bolt 28 is screwed to the upper end portion of the rod 9. Since the upper end of the rod 9 is fixed to the upper horizontal frame 20, the support member 24 can be attached to the upper horizontal frame 20 using a bolt 28 for fixing the upper horizontal frame 20 to the upper end of the rod 9. . Further, in this case, by loosening the screwing of the bolt 28 to the rod 9, the support member 24 can be turned and changed to the above-mentioned storage state or use state, so that the support member 24 can be stored or use state with a simple configuration. Can be changed to Further, since the center portion of the upper horizontal frame body 20 in a plan view can be fixed to the upper end portion of the rod 9 by the bolt 28, the upper horizontal frame body 20 can be firmly fixed to the rod 9 and, in addition, the support member 24 can be fixed to the upper portion. Since it is attached to the central portion of the horizontal frame body 20 in plan view, when the support member 24 is rotated, the attachment portion 25 can be positioned at the same position in the front-rear direction as the central portion of the car 1 in plan view. That is, the distance from one corner to the mounting portion 25 and the distance from the other corner to the mounting portion 25 of the two corners on the opposite side to the upper horizontal frame 20 of the car 1 in plan view are substantially the same. If the length of the safety belt is set so that work can be performed anywhere on the car 1, this rope can be shortened and the operator can hook the rope. Can be prevented from falling.
