Description
本発明は、交換可能な綱車を備えた巻上機、それを用いたエレベーター装置、プーリ装置に関する。
The present invention relates to a hoisting machine equipped with a replaceable sheave, an elevator device using the hoisting machine, and a pulley device.
交換可能な綱車を備えた巻上機の背景技術として、特許文献１が知られている。この文献の、例えば請求項１には、「昇降路内の固定枠に片持ち支持された固定軸と、この固定軸に回転自在に軸支された回転枠と、この回転枠と前記固定枠との間に構成されたモータと、前記回転枠の外側面に着脱自在に取り付けられて乗りかごを昇降させるロープが巻き掛けられる綱車と、前記回転枠の外側面に突設されて、前記綱車の取付穴が装着される軸受保持部とを備え、前記綱車と前記軸受保持部とが前記固定軸の軸心と同心に形成されたエレベーター用の巻上機であって、前記取付穴の内面と前記軸受保持部の外面とを同角度のテーパ状に形成したことを特徴とするエレベーター用の巻上機」が記載されている。
Patent Document 1 is known as a background technology for hoisting machines equipped with replaceable sheaves. In this document, for example, claim 1, "a fixed shaft cantilevered and supported by a fixed frame in a hoistway, a rotating frame rotatably supported by the fixed shaft, and the rotating frame and the fixed frame. A motor configured between the two, a rope wheel that is detachably attached to the outer surface of the rotating frame and around which a rope for raising and lowering a car is wound, and a rope wheel that is projected from the outer surface of the rotating frame. A hoisting machine for an elevator that includes a bearing holding portion to which a mounting hole for a rope wheel is mounted, and the rope wheel and the bearing holding portion are formed concentrically with the axis of the fixed shaft. A hoisting machine for an elevator, characterized in that the inner surface of the hole and the outer surface of the bearing holding portion are formed in a tapered shape at the same angle, is described.
この特許文献１では、同文献の図１や図６から明らかなように、巻上機（符号１５）の片持支持軸（符号２８）の自由端側から、溝が摩耗した古い綱車（符号３２）を取り外したり、新しい綱車を取り付けたりできるため、綱車が一体成型されたものであっても、その交換作業は容易であった。
In Patent Document 1, as is clear from FIGS. 1 and 6 of the same document, an old sheave with a worn groove from the free end side of the cantilever support shaft (reference numeral 28) of the hoisting machine (reference numeral 15) (reference numeral 15). Since the reference numeral 32) can be removed and a new sheave can be attached, even if the sheave is integrally molded, the replacement work is easy.
しかしながら、近年の建物の高層化やエレベーター装置の高速化に伴い、エレベーター装置の巻上機にはより高い耐負荷性能が求められており、綱車の軸を両持支持することで高負荷に耐える構造の巻上機が増えつつある。このような巻上機では、軸の先端を除振架台（ペデスタル）で支持する構造を採用することが多く、綱車を交換するには、古い綱車の取り外し前のペデスタルの取り外し作業と、新しい綱車の取り付け後のペデスタルの取り付け作業が必要となるため、綱車の軸を両持支持する巻上機では綱車の交換作業が簡単ではなかった。
However, with the recent increase in the height of buildings and the speeding up of elevator devices, higher load-bearing performance is required for the hoisting machines of elevator devices, and by supporting both sheave shafts, the load can be increased. The number of hoisting machines with a structure that can withstand is increasing. Such hoisting machines often adopt a structure in which the tip of the shaft is supported by a vibration isolation frame (pedestal), and in order to replace the sheave, the pedestal removal work before removing the old sheave and the removal work of the pedestal are required. Since it is necessary to install the pedestal after installing the new sheave, it was not easy to replace the sheave with a hoist that supports both sides of the sheave shaft.
そこで、本発明は、綱車の軸を両持支持した構成であっても、ペデスタルを取り外すことなく、綱車を簡単に交換できる巻上機を提供することを目的とする。
Therefore, an object of the present invention is to provide a hoisting machine that can easily replace the sheave without removing the pedestal even if the shaft of the sheave is supported by both sides.
上記課題を解決するために、本発明の巻上機は、主軸の外周面に固定されたディスクと、前記主軸の一端を支持するペデスタルと、前記主軸の他端を支持する筐体と、前記ディスクの一面側に取り付けられ、外周面に溝部を設けた綱車と、前記ディスクの他面側に取り付けられたロータと、前記ロータと対向するように前記筐体に取り付けられたステータと、を具備する巻上機であって、前記綱車は、複数の円弧状綱車を組み合わせて、全体として環状に構成したものである巻上機とした。
In order to solve the above problems, the hoisting machine of the present invention includes a disk fixed to the outer peripheral surface of the spindle, a pedestal that supports one end of the spindle, a housing that supports the other end of the spindle, and the above. A sheave mounted on one side of the disc and provided with a groove on the outer peripheral surface, a rotor mounted on the other side of the disc, and a stator mounted on the housing so as to face the rotor. The hoisting machine is a hoisting machine that is formed by combining a plurality of arc-shaped sheaves to form an annular shape as a whole.
本発明の巻上機によれば、綱車の軸を両持支持した構成であっても、ペデスタルを取り外すことなく、綱車を簡単に交換することができる。

Then, one end of the main rope 5 is connected to the car 6 arranged in the hoistway 1, and the other end of the main rope 5 is connected to the balance weight 7 arranged in the hoistway 1.

As shown here, the hoisting machine 3 has a base 30 mounted on the floor of the machine room 2, and a pedestal 31 is fixed to the upper surface of the base 30, and the pedestal 31 fixes the hoisting machine 3 to the hoisting machine 3. One end (tip side) of the main shaft 32 is rotatably supported. Further, a disc 33 is fixed to the outer peripheral surface of the spindle 32, and brake devices 34A and 34B for applying a braking force to the rotating disc 33 are arranged above the hoisting machine 3.
図３は、図２のＡ－Ａ線に沿った断面図である。ここに示すように、巻上機３の主軸３２は、一端（先端側）がペデスタル３１側の軸受３５Ａによって回転可能に支持され、他端が筺体３６側の軸受３５Ｂによって回転可能に支持されている。また、主軸３２の軸方向中央の外周面には、ボス部３２ａが形成されており、このボス部３２ａの外周面にディスク３３が嵌合されている。そして、ディスク３３のペデスタル３１側に、複数本のボルト４ａによって綱車４が取り外し可能に取り付けられている。
FIG. 3 is a cross-sectional view taken along the line AA of FIG. As shown here, one end (tip side) of the spindle 32 of the hoisting machine 3 is rotatably supported by the bearing 35A on the pedestal 31 side, and the other end is rotatably supported by the bearing 35B on the housing 36 side. There is. Further, a boss portion 32a is formed on the outer peripheral surface of the main shaft 32 at the center in the axial direction, and the disc 33 is fitted on the outer peripheral surface of the boss portion 32a. A sheave 4 is detachably attached to the pedestal 31 side of the disc 33 by a plurality of bolts 4a.
また、筺体３６には、主軸３２の他端側の外周を包囲するように環状の収納部３６ａが形成されており、この収納部３６ａの内周側には環状のステータ３７が固定されている。一方、ディスク３３の筐体３６側には、収納部３６ａ内の外周側に突出するロータ３８が固定されている。ステータ３７とロータ３８は所定のギャップを介して対向配置されており、両者によって巻上機３を駆動させるモータが構成される。
Further, the housing 36 is formed with an annular storage portion 36a so as to surround the outer periphery of the other end side of the main shaft 32, and an annular stator 37 is fixed to the inner peripheral side of the storage portion 36a. .. On the other hand, a rotor 38 projecting to the outer peripheral side in the storage portion 36a is fixed to the housing 36 side of the disk 33. The stator 37 and the rotor 38 are arranged to face each other with a predetermined gap, and both of them form a motor for driving the hoisting machine 3.
なお、ステータ３７は、例えば、積層された電磁鋼板と、この積層された電磁鋼板に巻回されたステータコイルなどで構成され、ロータ３８は、例えば、周方向に沿って所定の間隔を空けて固定された複数の磁石などで構成される。
The stator 37 is composed of, for example, a laminated electromagnetic steel plate and a stator coil wound around the laminated electromagnetic steel plate, and the rotor 38 is, for example, spaced at a predetermined interval along the circumferential direction. It is composed of a plurality of fixed magnets.
図４は、ディスク３３と綱車４の連結部を拡大した断面図である。ここに示すように、外周面に主索５を巻き掛ける溝部４ｆを形成した綱車４は、ペデスタル３１側（図４の右側）からディスク３３の結合部３３ａに嵌め込まれ、綱車４のボルト固定部４ｄの貫通孔４ｅに挿入したボルト４ａでディスク３３のねじ孔３３ｄに締結される構造となっている。
FIG. 4 is an enlarged cross-sectional view of the connecting portion between the disc 33 and the sheave 4. As shown here, the sheave 4 having a groove 4f around which the main rope 5 is wound is fitted into the joint 33a of the disc 33 from the pedestal 31 side (right side in FIG. 4), and the bolt of the sheave 4 is fitted. The structure is such that the bolt 4a inserted into the through hole 4e of the fixing portion 4d is fastened to the screw hole 33d of the disc 33.
また、ディスク３３と綱車４の連結をより強固にするため、綱車４の内周面には、図４の右側から左側に向かって内径が徐々に増大するテーパ嵌合面４ｂが形成されており、これに合致するように、結合部３３ａの外周面には、右側から左側に向かって外径が徐々に増大する逆テーパ嵌合面３３ｃが形成されている。さらに、綱車４の先端部に設けた押さえ部４ｃを、ディスク３３の嵌合凹部３３ｂに嵌め込むことで、綱車４の径方向位置を正確に位置決めすることができる。
Further, in order to further strengthen the connection between the disc 33 and the sheave 4, a tapered fitting surface 4b whose inner diameter gradually increases from the right side to the left side of FIG. 4 is formed on the inner peripheral surface of the sheave 4. A reverse taper fitting surface 33c whose outer diameter gradually increases from the right side to the left side is formed on the outer peripheral surface of the coupling portion 33a so as to match this. Further, by fitting the holding portion 4c provided at the tip end portion of the sheave 4 into the fitting recess 33b of the disc 33, the radial position of the sheave 4 can be accurately positioned.
次に、図５と図６を用いて、本実施例の綱車４の詳細を説明する。図５は、綱車４をペデスタル３１側から見た正面図であり、図６は図５のＢ－Ｂ線に沿った断面図である。両図から明らかなように、本実施例の綱車４の円周方向は、分割面Ｃ上側の半環状綱車４１と、分割面Ｃ下側の半環状綱車４２に分割されており、両者を組み合わせることで、全体として環状構成となる。なお、図５に示すように、上述した貫通孔４ｅは、半環状綱車４１，４２の内周側の円周方向にほぼ等間隔で複数形成されている。
Next, the details of the sheave 4 of this embodiment will be described with reference to FIGS. 5 and 6. FIG. 5 is a front view of the sheave 4 as viewed from the pedestal 31 side, and FIG. 6 is a cross-sectional view taken along the line BB of FIG. As is clear from both figures, the circumferential direction of the sheave 4 of this embodiment is divided into a semi-annular sheave 41 on the upper side of the dividing surface C and a semi-annular sheave 42 on the lower side of the dividing surface C. By combining both, a circular structure is formed as a whole. As shown in FIG. 5, a plurality of the above-mentioned through holes 4e are formed at substantially equal intervals in the circumferential direction on the inner peripheral side of the semi-annular sheaves 41 and 42.
このように、本実施例の綱車４は、半環状綱車４１，４２に分割できるため、溝部４ｆが摩耗した古い綱車４を交換する際には、半環状綱車４１側のボルト４ａを全て取り外せば、ペデスタル３１を取り外すことなく、半環状綱車４１を簡単に取り外すことができ、半環状綱車４２側のボルト４ａを全て取り外せば、ペデスタル３１を取り外すことなく、半環状綱車４２を簡単に取り外すことができる。
As described above, since the sheave 4 of the present embodiment can be divided into the semi-annular sheaves 41 and 42, when the old sheave 4 whose groove 4f is worn is replaced, the bolt 4a on the semi-annular sheave 41 side is replaced. The semi-annular sheave 41 can be easily removed without removing the pedestal 31 by removing all of the above, and the semi-annular sheave 41 can be easily removed without removing the pedestal 31 by removing all the bolts 4a on the semi-annular sheave 42 side. The 42 can be easily removed.
その後、ペデスタル３１がそのままの状態でも大凡逆の手順で新品の綱車４を簡単に取り付けることができる。この組立時、新品の綱車４も、結合部３３ａの逆テーパ嵌合面３３ｃに嵌合されるテーパ嵌合面４ｂを有しており、また結合部３３ａの嵌合凹部３３ｂに嵌め込まれる押さえ部４ｃを有しているため、容易に位置決めまたは仮保持することができる。その後、複数本のボルト４ａを締め付けるが、ボルト４ａの位置はペデスタル３１の上端よりも上方部に位置しているため、締め付けを簡単に行うことができる。また、主軸３２を回転することができるなら、主軸３２を回転させながら綱車４と結合部３３ａ間のボルト４ａの位置を作業しやすい位置に調整することもできる。
After that, even if the pedestal 31 remains as it is, a new sheave 4 can be easily attached by roughly reversing the procedure. At the time of this assembly, the new sheave 4 also has a tapered fitting surface 4b that is fitted to the reverse taper fitting surface 33c of the joint portion 33a, and also has a presser that is fitted into the fitting recess 33b of the joint portion 33a. Since it has a portion 4c, it can be easily positioned or temporarily held. After that, a plurality of bolts 4a are tightened, but since the position of the bolts 4a is located above the upper end of the pedestal 31, the tightening can be easily performed. Further, if the spindle 32 can be rotated, the position of the bolt 4a between the sheave 4 and the coupling portion 33a can be adjusted to a position where it is easy to work while rotating the spindle 32.
また半環状綱車４１，４２にはテーパ嵌合面４ｂを形成し、結合部３３ａには嵌め込まれた各半環状綱車４１，４２のテーパ嵌合面４ｂを受けるように逆テーパ嵌合面３３ｃを形成し、また半環状綱車４１，４２における結合部３３ａへの嵌め込み側先端部には押さえ部４ｃを形成し、結合部３３ａには押さえ部４ｃが嵌め込まれるように受ける嵌合凹部３３ｂを形成している。
Further, a tapered fitting surface 4b is formed on the semi-annular sheaves 41 and 42, and a reverse tapered fitting surface is received on the tapered fitting surface 4b of each of the semi-annular sheaves 41 and 42 fitted in the joint 33a. A fitting recess 33b is formed so that the holding portion 4c is formed at the tip of the semi-annular sheaves 41 and 42 on the fitting side to the fitting portion 33a, and the holding portion 4c is fitted into the connecting portion 33a. Is forming.
このような構成であるため、綱車４の交換を行う際に、半環状綱車４１，４２における結合部３３ａへの嵌め込み側先端部に形成された押さえ部４ｃを作業者が目視できないとしても、テーパ嵌合面４ｂと逆テーパ嵌合面３３ｃの嵌め合いを利用しながら簡単に両者を嵌め込み状態とすることができる。また嵌め込みの最終位置では、押さえ部４ｃと嵌合凹部３３ｂとの嵌め合いによって簡単に位置決めすることができる。
Due to such a configuration, when the sheave 4 is replaced, even if the operator cannot see the holding portion 4c formed at the tip of the semi-annular sheaves 41 and 42 on the fitting side 33a. , Both can be easily brought into the fitted state while utilizing the fitting of the tapered fitting surface 4b and the reverse taper fitting surface 33c. Further, at the final position of fitting, positioning can be easily performed by fitting the pressing portion 4c and the fitting recess 33b.
尚、図５、図６では、円周方向に二分割した同一形状の半環状綱車４１，４２を例示したが、各半環状綱車は同一形状でなくても良く、また、三つ以上の円弧状綱車を組み合わせて環状の綱車４を構成しても良い。また上述した実施例は、ペデスタル３１を有する巻上機３に適用した場合について説明したが、エレベーター装置においては、巻上機３以外にも綱車４に類似の構成が存在する。例えば、図１に示したプーリ８のように回転軸が両持支持されるプーリ装置であれば、プーリ８の構成を、図５や図６に例示した綱車４のように分離可能な構成としても良い。
In addition, in FIGS. 5 and 6, semi-annular sheaves 41 and 42 having the same shape divided into two in the circumferential direction are illustrated, but each semi-annular sheave does not have to have the same shape, and three or more. An annular sheave 4 may be formed by combining the arc-shaped sheaves of the above. Further, although the above-described embodiment has been described when applied to the hoisting machine 3 having the pedestal 31, the elevator device has a configuration similar to that of the sheave 4 in addition to the hoisting machine 3. For example, in the case of a pulley device in which the rotating shaft is supported by both sides like the pulley 8 shown in FIG. 1, the configuration of the pulley 8 can be separated like the sheave 4 illustrated in FIGS. 5 and 6. May be.
以上説明した本実施例によれば、摩耗した綱車４を交換する場合、ボルト４ａを取り外すだけで、ペデスタル３１を取り外すことなく、古い半環状綱車４１，４２を簡単に取り外すことができ、その後、新品の半環状綱車４１，４１を簡単に取り付けることができる。
According to the present embodiment described above, when replacing the worn sheave 4, the old semi-annular sheaves 41 and 42 can be easily removed by simply removing the bolt 4a without removing the pedestal 31. After that, new semi-annular sheaves 41 and 41 can be easily attached.
尚、本発明は、上述した実施例に限定するものではなく、様々な変形例が含まれる。例えば、上述した実施例は本発明を分かり易く説明するために詳細に説明したものであり、必ずしも説明した全ての構成を備えるものに限定するものではない。またある実施例の構成の一部を他の実施例の構成に置き換えることが可能であり、また、ある実施例の構成に他の実施例の構成を加えることも可能である。また、各実施例の構成の一部について、他の構成の追加、削除、置換をすることが可能である。
The present invention is not limited to the above-mentioned examples, and includes various modifications. For example, the above-described examples have been described in detail in order to explain the present invention in an easy-to-understand manner, and are not necessarily limited to those having all the described configurations. It is also possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. In addition, it is possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.
