Description
この発明は、昇降体(例えばかごや釣合おもり等)に設けられ、昇降体を吊り下げる主索が巻き掛けられるエレベータの吊り車装置に関するものである。
The present invention relates to an elevator suspension device that is provided on a lifting body (for example, a car or a counterweight) and on which a main rope for suspending the lifting body is wound.
従来、一対のガイドレール間に配置されたかごを主索により吊り下げるために、主索が巻き掛けられる吊り車を、かご室を囲むかご枠の下梁に設けるようにしたエレベータが知られている。かご枠の縦柱には、ガイドレールに案内されるガイドシューが設けられている。吊り車及びガイドシューは、水平方向について互いに離して配置されている。主索は、かご枠の縦柱の背面とかご室との間を通して吊り車に巻き掛けられている。これにより、ガイドシューと吊り車とが高さ方向について並ぶことが回避され、かご全体の高さ寸法の縮小化が図られている(特許文献1参照)。
Conventionally, in order to suspend a car arranged between a pair of guide rails by a main rope, there has been known an elevator in which a suspension vehicle around which a main rope is wound is provided on a lower beam of a car frame surrounding a car room. Yes. A guide shoe guided by a guide rail is provided on the vertical column of the car frame. The suspension wheel and the guide shoe are arranged apart from each other in the horizontal direction. The main rope is wound around a suspension car through the back of the vertical column of the car frame and the car room. Thereby, it is avoided that the guide shoe and the suspension wheel are arranged in the height direction, and the height dimension of the entire car is reduced (see Patent Document 1).
しかし、上記のような従来のエレベータでは、ガイドシューが設けられた縦柱と吊り車との間に主索を通す空間を確保する必要があるので、ガイドシュー、吊り車及び主索を配置するためのスペースが大きくなってしまう。かごは、一対のガイドレール間の限られたスペースに配置されるので、ガイドシュー、吊り車及び主索を配置するためのスペースが大きくなることにより、かごの容積が小さくなってしまう。
However, in the conventional elevators as described above, it is necessary to secure a space for the main rope to pass between the vertical column provided with the guide shoe and the suspension vehicle, so the guide shoe, the suspension vehicle and the main rope are arranged. The space for it becomes large. Since the car is disposed in a limited space between the pair of guide rails, the space for arranging the guide shoe, the suspension wheel, and the main rope is increased, so that the volume of the car is reduced.
また、従来のエレベータでは、ガイドシューと吊り車とが互いに離して別個に設けられているので、ガイドシュー及び吊り車を別個に取り付ける必要があり、ガイドシュー及び吊り車をかごに取り付ける作業に手間がかかってしまう。
In addition, in the conventional elevator, the guide shoe and the suspension vehicle are provided separately from each other. Therefore, it is necessary to attach the guide shoe and the suspension vehicle separately, and it is troublesome to attach the guide shoe and the suspension vehicle to the car. It will take.
さらに、ガイドシューと吊り車との干渉を避けるために、かご枠の下梁の下面に吊り車梁を傾斜させて取り付け、吊り車梁に一対の吊り車を取り付けることも考えられるが、かご全体の重量が吊り車梁の分だけ重くなってしまうだけでなく、吊り車梁をかごに取り付ける作業の手間もかかってしまう。
Furthermore, in order to avoid interference between the guide shoe and the suspension car, it is conceivable that the suspension car beam is inclined and attached to the lower surface of the lower beam of the car frame, and a pair of suspension cars is attached to the suspension car beam. Not only will the weight of the car be increased by the amount of the suspended vehicle beam, but it will also take time and labor to attach the suspended vehicle beam to the car.
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、設置スペースを縮小化することができるとともに、昇降体に対する取付作業を容易にすることができるエレベータの吊り車装置を得ることを目的とする。
The present invention has been made in order to solve the above-described problems, and provides an elevator suspension device that can reduce the installation space and facilitate the mounting work on the lifting body. For the purpose.

この発明によるエレベータの吊り車装置によれば、吊り車及びガイド体を互いに離して配置する必要がなくなり、吊り車装置の設置スペースの縮小化を図ることができる。また、昇降体に対して吊り車とガイド体とを別個に取り付ける必要がなくなるので、昇降体に対する吊り車装置の取付作業を容易にすることができる。
According to the elevator suspension device of the present invention, it is not necessary to dispose the suspension vehicle and the guide body apart from each other, and the installation space of the suspension vehicle device can be reduced.

FIG. 4 is a side view showing the car suspension device 13 of FIG. Moreover, FIG. 5 is principal part sectional drawing which shows the car suspension apparatus 13 of FIG. As shown in FIG. 5, the suspension vehicle 18 includes a boss portion 18 a provided on the axis of the suspension vehicle 18, an annular annular portion 18 b that surrounds the boss portion 18 a and forms an outer peripheral portion of the suspension vehicle 18, It has the connection part 18c which connects between the boss | hub part 18a and the cyclic | annular part 18b. Each thickness dimension (dimension about the axial direction of the suspension wheel 18) of the boss | hub part 18a and the cyclic | annular part 18b is larger than the thickness dimension of the connection part 18c. The boss portion 18a is provided with a bearing hole 30 penetrating the boss portion 18a. A bearing (not shown) attached to the rotary shaft 17 is fitted in the bearing hole 30. The suspension wheel 18 is rotatably attached to the rotary shaft 17 via a bearing.
環状部18bの外周面には、複数本(この例では、4本)の主索用溝20が吊り車18の回転方向に沿って設けられている。各主索8は、主索用溝20に挿入された状態で主索用溝20に沿って吊り車18に巻き掛けられている。
A plurality of (four in this example) main rope grooves 20 are provided along the rotation direction of the suspension wheel 18 on the outer peripheral surface of the annular portion 18b. Each main rope 8 is wound around a suspension wheel 18 along the main rope groove 20 while being inserted into the main rope groove 20.
ガイド体19は、吊り車18の回転方向に沿って各主索用溝20と平行に環状部18b(吊り車18の外周部)に設けられた環状体である。ガイド体19は、吊り車18と同軸に配置されている。また、ガイド体19は、回転軸17を中心に吊り車18と一体に回転される。ガイド体19は、同一材料により吊り車18と一体成形されている。この例では、ガイド体19及び吊り車18が、例えば鉄等の金属材料により鋳造で一体成形されている。さらに、ガイド体19は、回転軸17の軸線方向(即ち、吊り車18の厚さ方向)について吊り車18の中央に設けられている。これにより、かご吊り車装置13の形状は、回転軸17の軸線方向について左右対称の形状となっている。この例では、図4及び図5に示すように、ガイド体19の両側に主索用溝20が2本ずつ設けられている。
The guide body 19 is an annular body provided in the annular portion 18 b (the outer peripheral portion of the suspension wheel 18) in parallel with the main rope grooves 20 along the rotation direction of the suspension wheel 18. The guide body 19 is arranged coaxially with the suspension wheel 18. Further, the guide body 19 is rotated integrally with the suspension wheel 18 around the rotation shaft 17. The guide body 19 is integrally formed with the suspension wheel 18 from the same material. In this example, the guide body 19 and the suspension wheel 18 are integrally formed by casting with a metal material such as iron. Furthermore, the guide body 19 is provided at the center of the suspension wheel 18 in the axial direction of the rotating shaft 17 (that is, the thickness direction of the suspension wheel 18). Thereby, the shape of the car suspension device 13 is symmetrical with respect to the axial direction of the rotating shaft 17. In this example, as shown in FIGS. 4 and 5, two main rope grooves 20 are provided on both sides of the guide body 19.
ガイド体19の外径は、吊り車18の外径よりも大きくなっている。また、ガイド体19には、かごガイドレール2の突出部(一部)が挿入されるガイド溝21が吊り車18の回転方向に沿って設けられている。ガイド溝21は、吊り車18及びガイド体19の径方向外側に開放されている。かごガイドレール2の突出部は、図3に示すように、かご3の幅方向両端部でガイド溝21に挿入されている。
The outer diameter of the guide body 19 is larger than the outer diameter of the suspension wheel 18. Further, the guide body 19 is provided with a guide groove 21 into which the protruding portion (a part) of the car guide rail 2 is inserted along the rotation direction of the suspension wheel 18. The guide groove 21 is opened outward in the radial direction of the suspension wheel 18 and the guide body 19. As shown in FIG. 3, the protruding portion of the car guide rail 2 is inserted into the guide groove 21 at both ends in the width direction of the car 3.
主索8の吊り車18に巻き掛けられた部分の中心線、及びガイド溝21の底面は、回転軸17の軸線を中心とする共通の仮想円筒面上に存在している。即ち、回転軸17の軸線方向に沿って吊り車18及びガイド体19を見たときに、主索8の吊り車18に巻き掛けられた部分の中心線によって形成される円弧と、ガイド溝21の底面によって形成される円とが、回転軸17の軸線を中心とする共通の仮想円上に重なっている。この例では、図5に示すように、吊り車18の外周面が存在する仮想円筒面A上に、主索8の吊り車18に巻き掛けられた部分の中心線及びガイド溝21の底面のそれぞれが存在するように、各主索用溝20及びガイド溝21のそれぞれの深さが設定されている。これにより、かご3がかごガイドレール2に沿って移動されるときには、吊り車18の回転速度、かご3に対する主索8の移動速度、及びかご3の移動速度のそれぞれが一致するようになる。
The center line of the portion of the main rope 8 wound around the suspension wheel 18 and the bottom surface of the guide groove 21 are present on a common virtual cylindrical surface centering on the axis of the rotating shaft 17. That is, when the suspension wheel 18 and the guide body 19 are viewed along the axial direction of the rotary shaft 17, the arc formed by the center line of the portion of the main rope 8 wound around the suspension wheel 18 and the guide groove 21. And a circle formed by the bottom surface of the same overlaps with a common virtual circle centered on the axis of the rotating shaft 17. In this example, as shown in FIG. 5, the center line of the portion of the main rope 8 wound around the suspension wheel 18 and the bottom surface of the guide groove 21 on the virtual cylindrical surface A on which the outer peripheral surface of the suspension wheel 18 exists. The depths of the main rope grooves 20 and the guide grooves 21 are set so that they exist. As a result, when the car 3 is moved along the car guide rail 2, the rotational speed of the suspension wheel 18, the moving speed of the main rope 8 with respect to the car 3, and the moving speed of the car 3 are matched.
釣合おもり吊り車装置14の構成は、かご吊り車装置13の構成と同様である。釣合おもり吊り車装置14のガイド溝には、釣合おもりガイドレールの突出部が挿入されている。従って、釣合おもり吊り車装置14は、主索8が巻き掛けられた状態で釣合おもり4の重量を支持する機能と、釣合おもりガイドレールに沿って釣合おもり4を案内する機能とを兼ね備えた装置となっている。
The configuration of the counterweight suspension vehicle device 14 is the same as the configuration of the car suspension vehicle device 13. The protruding portion of the counterweight guide rail is inserted into the guide groove of the counterweight suspension vehicle device 14. Therefore, the counterweight suspension vehicle device 14 has a function of supporting the weight of the counterweight 4 while the main rope 8 is wound, and a function of guiding the counterweight 4 along the counterweight guide rail. It has become a device that combines.
次に、動作について説明する。巻上機5の駆動力により駆動綱車7が回転されると、主索8が移動されて、かご3がかごガイドレール2に沿って移動されるとともに、釣合おもり4が釣合おもりガイドレールに沿って移動される。このとき、かご吊り車装置13は、かごガイドレール2の突出部がガイド溝21に挿入された状態でかごガイドレール2に案内されるとともに、主索8の移動に応じて回転されながら、かご3と一体に移動される。また、このとき、釣合おもり吊り車装置14は、釣合おもりガイドレールの突出部が釣合おもり吊り車装置14のガイド溝に挿入された状態で釣合おもりガイドレールに案内されるとともに、主索8の移動に応じて回転されながら、釣合おもり4と一体に移動される。
Next, the operation will be described. When the driving sheave 7 is rotated by the driving force of the hoist 5, the main rope 8 is moved, the car 3 is moved along the car guide rail 2, and the counterweight 4 is counterbalanced. It is moved along the rail. At this time, the car suspension device 13 is guided by the car guide rail 2 in a state where the protruding portion of the car guide rail 2 is inserted into the guide groove 21 and is rotated in accordance with the movement of the main rope 8. 3 is moved together. At this time, the counterweight suspension vehicle device 14 is guided to the counterweight guide rail with the protruding portion of the counterweight suspension guide rail being inserted into the guide groove of the counterweight suspension vehicle device 14. While being rotated in accordance with the movement of the main rope 8, it is moved together with the counterweight 4.
かご3がかごガイドレール2に沿って移動されるときには、一対のかごガイドレール2のうち、一方のかごガイドレール2に対してはかご吊り車装置13の回転方向がかご3の移動方向に対して順方向となるが、他方のかごガイドレール2に対してはかご吊り車装置13の回転方向がかご3の移動方向に対して逆方向になる。このとき、かご3には、図2に示すように、主索8がかご吊り車装置13から送り出されることによって生じるモーメントBが作用している。主索8がかご吊り車装置13から送り出されることによって生じるモーメントBは、かご3の移動方向に対して逆方向に回転されるかご吊り車装置13をかごガイドレール2に押し付ける力を弱める方向へ作用し、かご3の移動方向に対して順方向に回転されるかご吊り車装置13をかごガイドレール2に押し付ける力を強める方向へ作用する。
When the car 3 is moved along the car guide rail 2, the rotation direction of the car suspension device 13 is relative to the moving direction of the car 3 with respect to one car guide rail 2 of the pair of car guide rails 2. However, the rotation direction of the car suspension device 13 is opposite to the moving direction of the car 3 with respect to the other car guide rail 2. At this time, as shown in FIG. 2, a moment B generated by the main rope 8 being sent out from the car suspension device 13 acts on the car 3. The moment B generated by the main rope 8 being sent out from the car suspension device 13 is in a direction that weakens the force that presses the car suspension device 13 that is rotated in the opposite direction to the moving direction of the car 3 against the car guide rail 2. It acts, and acts in the direction which strengthens the force which presses the car suspension apparatus 13 rotated in the forward direction with respect to the moving direction of the car 3 against the car guide rail 2.
例えば、図2に示すように、かご3が下方向へ移動するときには、図2の左右のかご吊り車装置13のうち、左側のかご吊り車装置13の回転方向がかご3の移動方向に対して順方向となり、右側のかご吊り車装置13の回転方向がかご3の移動方向に対して逆方向となる。このとき、主索8が各かご吊り車装置13から送り出されることによってかご3に生じるモーメントBは、回転方向が逆方向となっている図2の右側のかご吊り車装置13をかごガイドレール2に押し付ける力を弱め、回転方向が順方向となっている図2の左側のかご吊り車装置13をかごガイドレール2に押し付ける力を強める方向へかご3に作用する。これにより、かご3がかごガイドレール2に沿って移動されるときには、かご3の移動に対する抵抗力のうち、かご吊り車装置13の回転によって生じる抵抗力は極めて小さい状態となる。
For example, as shown in FIG. 2, when the car 3 moves downward, the rotation direction of the left car suspension device 13 of the left and right car suspension devices 13 of FIG. 2 is relative to the movement direction of the car 3. The direction of rotation of the right-hand car suspension device 13 is opposite to the moving direction of the car 3. At this time, the moment B generated in the car 3 when the main rope 8 is sent out from each car suspension device 13 causes the car suspension device 13 on the right side in FIG. 2 is applied to the car 3 in a direction in which the force for pressing the car suspension device 13 on the left side in FIG. Thereby, when the car 3 is moved along the car guide rail 2, the resistance force generated by the rotation of the car suspension device 13 among the resistance force against the movement of the car 3 is extremely small.
また、釣合おもり4が釣合おもりガイドレールに沿って移動されるときには、一対の釣合おもりガイドレールのうち、一方の釣合おもりガイドレールに対しては釣合おもり吊り車装置14の回転方向が釣合おもり4の移動方向に対して順方向となるが、他方の釣合おもりガイドレールに対しては釣合おもり吊り車装置14の回転方向が釣合おもり4の移動方向に対して逆方向になる。このとき、かご3と同様に、主索8が釣合おもり吊り車装置14から送り出されることによって生じるモーメントが釣合おもり4に作用している。主索8が釣合おもり吊り車装置14から送り出されることによって生じるモーメントは、釣合おもり吊り車装置14の回転方向が逆方向になる側の他方の釣合おもりガイドレールに釣合おもり吊り車装置14が押し付けられる力を弱め、釣合おもり吊り車装置14の回転方向が順方向になる側の一方の釣合おもりガイドレールに釣合おもり吊り車装置14が押し付けられる力を強める方向へ作用する。これにより、釣合おもり4が釣合おもりガイドレールに沿って移動されるときには、釣合おもり4の移動に対する抵抗力のうち、釣合おもり吊り車装置14の回転によって生じる抵抗力は極めて小さい状態となる。
Further, when the counterweight 4 is moved along the counterweight guide rail, the counterweight suspension device 14 rotates with respect to one counterweight guide rail of the pair of counterweight guide rails. Although the direction is the forward direction with respect to the moving direction of the counterweight 4, the rotating direction of the counterweight suspension device 14 is relative to the moving direction of the counterweight 4 with respect to the other counterweight guide rail. Reverse direction. At this time, similarly to the car 3, a moment generated by the main rope 8 being sent out from the counterweight suspension vehicle device 14 acts on the counterweight 4. The moment generated by the main rope 8 being sent out from the counterweight suspension vehicle device 14 is caused by the counterweight suspension vehicle on the other counterweight guide rail on the side where the rotation direction of the counterweight suspension vehicle device 14 is reversed. The force with which the device 14 is pressed is weakened, and the force is applied to increase the force with which the counterweight suspension vehicle 14 is pressed against one counterweight guide rail on the side where the rotation direction of the counterweight suspension device 14 becomes the forward direction. To do. Thereby, when the counterweight 4 is moved along the counterweight guide rail, the resistance force generated by the rotation of the counterweight suspension vehicle device 14 is extremely small among the resistance force against the movement of the counterweight 4. It becomes.
このようなかご吊り車装置13では、かごガイドレール2に案内されるガイド体19が吊り車18の回転方向に沿って吊り車18に設けられ、吊り車18及びガイド体19が一体に回転されるようになっているので、吊り車18及びガイド体19を互いに離して配置する必要がなくなり、かご吊り車装置13の設置スペースの縮小化を図ることができる。また、かご3に対して吊り車18とガイド体19とを別個に取り付ける必要がなくなるので、かご3に対するかご吊り車装置13の取付作業を容易にすることができる。釣合おもり吊り車装置14も、かご吊り車装置13と同様の構成であるので、釣合おもり吊り車装置14の設置スペースの縮小化を図ることができるとともに、釣合おもり4に対する釣合おもり吊り車装置14の取付作業を容易にすることができる。
In such a car suspension device 13, the guide body 19 guided by the car guide rail 2 is provided in the suspension car 18 along the rotation direction of the suspension car 18, and the suspension car 18 and the guide body 19 are rotated together. Therefore, it is not necessary to dispose the suspension vehicle 18 and the guide body 19 apart from each other, and the installation space of the car suspension device 13 can be reduced. Further, since it is not necessary to separately attach the suspension wheel 18 and the guide body 19 to the car 3, the work of attaching the car suspension device 13 to the car 3 can be facilitated. Since the counterweight suspension vehicle device 14 has the same configuration as the car suspension vehicle device 13, it is possible to reduce the installation space of the counterweight suspension vehicle device 14 and to counterbalance the counterweight 4. The attachment work of the suspension vehicle apparatus 14 can be made easy.
また、かご吊り車装置13では、主索8の吊り車18に巻き掛けられた部分の中心線、及びガイド溝21の底面は、回転軸17の軸線を中心とする共通の仮想円筒面A上に存在しているので、吊り車18の回転速度、かご3に対する主索8の移動速度、及びかご3の移動速度のそれぞれを一致させることができる。これにより、かご3を円滑に移動させることができる。釣合おもり吊り車装置14が設けられた釣合おもり4も、同様に、円滑に移動させることができる。
In the car suspension device 13, the center line of the portion of the main rope 8 wound around the suspension wheel 18 and the bottom surface of the guide groove 21 are on the common virtual cylindrical surface A centering on the axis of the rotating shaft 17. Therefore, the rotational speed of the suspension wheel 18, the moving speed of the main rope 8 relative to the car 3, and the moving speed of the car 3 can be matched. Thereby, the cage | basket | car 3 can be moved smoothly. Similarly, the counterweight 4 provided with the counterweight suspension vehicle device 14 can also be moved smoothly.
また、かご吊り車装置13では、吊り車18及びガイド体19は、一体成形されているので、部品点数を削減することができ、コストの低減化を図ることができる。釣合おもり吊り車装置14についても同様に、部品点数を削減することができ、コストの低減化を図ることができる。
Further, in the car suspension device 13, since the suspension vehicle 18 and the guide body 19 are integrally formed, the number of parts can be reduced and the cost can be reduced. Similarly, the counterweight suspension vehicle device 14 can also reduce the number of parts and can reduce the cost.
なお、上記の例では、かご吊り車装置13及び釣合おもり吊り車装置14のそれぞれの吊り車18及びガイド体19が金属材料により一体成形されているが、吊り車18及びガイド体19を同一の樹脂材料により一体成形してもよい。このようにすれば、かご3が移動されるときのガイド体19とかごガイドレール2との接触による騒音、及び釣合おもり4が移動されるときの釣合おもり吊り車装置14のガイド体と釣合おもりガイドレールとの接触による騒音のそれぞれを低減することができる。
In the above example, the suspension wheel 18 and the guide body 19 of the car suspension vehicle device 13 and the counterweight suspension vehicle device 14 are integrally formed of a metal material, but the suspension vehicle 18 and the guide body 19 are the same. The resin material may be integrally formed. In this way, the noise caused by the contact between the guide body 19 and the car guide rail 2 when the car 3 is moved, and the guide body of the counterweight suspension vehicle device 14 when the counterweight 4 is moved, Each noise caused by contact with the counterweight guide rail can be reduced.

図6は、この発明の実施の形態2によるかご吊り車装置13を示す要部断面図である。図において、かご吊り車装置13のガイド体19は、吊り車18と別体となっている。この例では、吊り車18及びガイド体19がいずれも、鉄等の金属材料により構成されている。吊り車18では、繋ぎ部18cの厚さ寸法の範囲から両側へ突出する環状部18bの厚さ方向両端部のうち、一端部のみが除去された状態となっている。ガイド体19は、環状部18bの厚さ方向一端部が除去されて形成された吊り車18の側面に設けられている。従って、この例では、かご吊り車装置13の形状が回転軸17の軸線方向(吊り車18の厚さ方向)について左右非対称の形状となっている。吊り車18に設けられた複数本(この例では、3本)の主索用溝20は、吊り車18の厚さ方向についてガイド体19の一方側にのみ存在している。Embodiment 2. FIG.
FIG. 6 is a cross-sectional view of a main part showing acar suspension device 13 according to Embodiment 2 of the present invention. In the figure, the guide body 19 of the car suspension device 13 is separate from the suspension vehicle 18. In this example, both the suspension wheel 18 and the guide body 19 are made of a metal material such as iron. In the suspension wheel 18, only one end portion is removed from both ends in the thickness direction of the annular portion 18 b protruding to both sides from the range of the thickness dimension of the connecting portion 18 c. The guide body 19 is provided on the side surface of the suspension wheel 18 formed by removing one end in the thickness direction of the annular portion 18b. Therefore, in this example, the shape of the car suspension device 13 is asymmetrical with respect to the axial direction of the rotating shaft 17 (the thickness direction of the suspension vehicle 18). A plurality of (three in this example) main rope grooves 20 provided in the suspension wheel 18 exist only on one side of the guide body 19 in the thickness direction of the suspension wheel 18.
図6は、この発明の実施の形態2によるかご吊り車装置13を示す要部断面図である。図において、かご吊り車装置13のガイド体19は、吊り車18と別体となっている。この例では、吊り車18及びガイド体19がいずれも、鉄等の金属材料により構成されている。吊り車18では、繋ぎ部18cの厚さ寸法の範囲から両側へ突出する環状部18bの厚さ方向両端部のうち、一端部のみが除去された状態となっている。ガイド体19は、環状部18bの厚さ方向一端部が除去されて形成された吊り車18の側面に設けられている。従って、この例では、かご吊り車装置13の形状が回転軸17の軸線方向(吊り車18の厚さ方向)について左右非対称の形状となっている。吊り車18に設けられた複数本(この例では、3本)の主索用溝20は、吊り車18の厚さ方向についてガイド体19の一方側にのみ存在している。
