Description

本発明の実施形態は、ワイヤロープの清掃に用いられる締付器具と、この締付器具を用いたロープ清掃方法に関する。 Embodiments of the present invention relate to a tightening device used for cleaning a wire rope and a rope cleaning method using the tightening device.

一般的に、エレベータでは、例えば乗りかごとカウンタウエイトとを連結するメインロープが巻き架けられた巻上機を駆動することによって、当該乗りかご及びカウンタウエイトを互いに反対方向に昇降動作させる。 Generally, in an elevator, for example, by driving a hoisting machine on which a main rope that connects a car and a counterweight is wound, the car and the counterweight are moved up and down in opposite directions.

このようなエレベータにおけるメインロープとしては、ワイヤロープが用いられる。ワイヤロープは、素線と称される細い鋼線が撚り合わされて形成される複数のストランドを、中央部の繊維心の周囲に撚り合わせて構成されたロープである。 A wire rope is used as the main rope in such an elevator. The wire rope is a rope formed by twisting a plurality of strands formed by twisting thin steel wires called strands around the fiber core in the center.

ところで、ワイヤロープが長期間使用されると、ワイヤロープに含有されるグリスが析出し、その析出したグリスが硬化するまたはゴミが付着する等によりエレベータの運行に支障を来す場合がある。 By the way, when a wire rope is used for a long period of time, the grease contained in the wire rope may be precipitated, and the deposited grease may be hardened or dust may adhere to the elevator operation.

このため、グリスの硬化またはゴミの付着を防止するために、定期的にワイヤロープを清掃する等のメンテナンスが必要となる。 For this reason, in order to prevent hardening of grease or adhesion of dust, maintenance such as periodically cleaning the wire rope is required.

ワイヤロープの清掃は、スクレーパまたはブラシを用いた作業員の人手によって行われる場合が多い。しかしながら、このような人手による清掃作業には、多大な労力及び時間がかかる。また、人手によってワイヤロープの谷部（ストランド間）に詰まったグリスを削ぎ取ることは困難である。 The wire rope is often cleaned manually by a worker using a scraper or a brush. However, such a manual cleaning operation requires a great deal of labor and time. Further, it is difficult to manually remove the grease clogged in the valley portions (between the strands) of the wire rope.

そこで、ワイヤロープの清掃を自動化するためのロープ清掃治具が考えられている。例えばワイヤロープの外周形状に型抜いた孔を有する回転部材をワイヤロープに装着して、この回転部材をワイヤロープの軸周りに回転させることによってグリスを削ぎ取るロープ清掃治具が開発されている。 Therefore, a rope cleaning jig for automating the cleaning of the wire rope has been considered. For example, a rope cleaning jig has been developed in which a rotating member having a hole cut in the outer peripheral shape of a wire rope is attached to the wire rope and the grease is scraped off by rotating the rotating member around the wire rope axis. .

エレベータにおけるメインロープは、一般的に、複数のワイヤロープから構成される。このようなメインロープを上述したロープ清掃治具を使用して清掃する場合、各ワイヤロープの軸周りに回転部材をそれぞれ装着する。その際、各ワイヤロープから回転部材が外れないように、例えば針金やホースバンドなどを用いて回転部材の周りを締め付けておく作業が必要となる。 A main rope in an elevator is generally composed of a plurality of wire ropes. When such a main rope is cleaned using the rope cleaning jig described above, a rotating member is mounted around the axis of each wire rope. At that time, it is necessary to tighten the periphery of the rotating member using, for example, a wire or a hose band so that the rotating member does not come off from each wire rope.

しかしながら、各ワイヤロープに装着された回転部材を針金で１つ１つ締め付ける作業は面倒であり、時間もかかる。また、一般的に知られているホースバンドには、締め付け用の操作レバーや固定用ボルトなどの金具が設けられており、ホースバンドを回転部材の周りに付けたときに幅を取る。このため、隣接するロープ間でホースバンドの金具が干渉することがあり、ロープ間ピッチが狭いエレベータには適用することができない。 However, the work of tightening the rotating members attached to the wire ropes one by one with a wire is troublesome and takes time. Further, generally known hose bands are provided with metal fittings such as a tightening operation lever and a fixing bolt, and take a width when the hose band is attached around the rotating member. For this reason, the metal fittings of the hose band may interfere between adjacent ropes and cannot be applied to an elevator with a narrow pitch between ropes.

本発明が解決しようとする課題は、ロープに清掃用の回転部材を装着して清掃する際に、隣接するロープ間で干渉することなく、回転部材を外周から締め付けてロープに固定することのできる締付器具及びロープ清掃方法を提供することを目的とする。 The problem to be solved by the present invention is that when a rotating member for cleaning is attached to a rope for cleaning, the rotating member can be clamped from the outer periphery and fixed to the rope without interference between adjacent ropes. An object is to provide a fastening device and a rope cleaning method.

一実施形態に係る締付器具は、ロープの軸周りに装着される清掃用の回転部材を上記ロープに固定する。上記締付器具は、円弧状に湾曲形成された少なくとも２つの部材が互いに回動自在に連結され、上記回転部材の外周を囲んでリング状に閉じた状態で固定され、上記回転部材を外周から上記ロープの径方向に締め付けて上記ロープに圧着し、リング状態のときに上記各部材はリング外周径内に収められる。 The tightening device according to an embodiment fixes a cleaning rotary member mounted around a rope axis to the rope. In the clamping device, at least two members curved in an arc shape are rotatably connected to each other, and are fixed in a state of being closed in a ring shape surrounding the outer periphery of the rotating member. The members are accommodated within the outer diameter of the ring when tightened in the radial direction of the rope and crimped to the rope.

以下、図面を参照して実施形態を説明する。 Hereinafter, embodiments will be described with reference to the drawings.

（第１の実施形態）
本実施形態に係るエレベータのロープ清掃治具（以下、単にロープ清掃治具と表記）は、例えば複数本のワイヤロープから構成されるメインロープの清掃に使用される治具である。なお、メインロープを構成する各ワイヤロープは、素線と称される細い鋼線が撚り合わされて形成される複数のストランドを、中央部の繊維心の周囲に撚り合わせて構成されたロープである。 (First embodiment)
An elevator rope cleaning jig (hereinafter simply referred to as a rope cleaning jig) according to the present embodiment is a jig used for cleaning a main rope composed of a plurality of wire ropes, for example. Each wire rope constituting the main rope is a rope formed by twisting a plurality of strands formed by twisting thin steel wires called strands around the fiber core at the center. .

まず、図１を参照して、本実施形態に係るエレベータのロープ清掃治具の設置位置について簡単に説明する。 First, with reference to FIG. 1, the installation position of the rope cleaning jig of the elevator which concerns on this embodiment is demonstrated easily.

エレベータにおいて、エレベータ制御装置１１は、例えば図示しない機械室内に設置され、巻上機１２の駆動制御を含むエレベータ全体の運行制御を行う。巻上機１２は、マシンビーム１３上に支持されており、エレベータ制御装置１１とともに機械室内に併設されている。巻上機１２の駆動軸にはメインシーブ（トラクションシーブ）１４が取り付けられており、当該メインシーブ１４の外周部にはメインロープ１５が巻き架けられている。メインロープ１５の一端は乗りかご１６に連結され、他端はカウンタウエイト（Ｃ／Ｗ）１７に連結されている。 In the elevator, the elevator control device 11 is installed in a machine room (not shown), for example, and performs operation control of the entire elevator including drive control of the hoisting machine 12. The hoisting machine 12 is supported on the machine beam 13 and is provided together with the elevator control device 11 in the machine room. A main sheave (traction sheave) 14 is attached to the drive shaft of the hoisting machine 12, and a main rope 15 is wound around the outer periphery of the main sheave 14. One end of the main rope 15 is connected to the car 16 and the other end is connected to a counterweight (C / W) 17.

なお、図１においては、便宜的にメインロープ１５は１本のロープであるように示されているが、当該メインロープ１５は、上記したように複数本のワイヤロープから構成されている。この複数本のワイヤロープには、潤滑または防錆のためにグリスが塗付されている。 In FIG. 1, the main rope 15 is shown as a single rope for convenience, but the main rope 15 is composed of a plurality of wire ropes as described above. The plurality of wire ropes are coated with grease for lubrication or rust prevention.

エレベータ制御装置１１の制御に基づいて巻上機１２が駆動されると、メインロープ１５が巻き架けられているメインシーブ１４が回転し、当該メインロープ１５に連結されている乗りかご１６及びカウンタウエイト１７がつるべ式に昇降動作する。 When the hoisting machine 12 is driven based on the control of the elevator controller 11, the main sheave 14 around which the main rope 15 is wound rotates, and the car 16 and the counterweight connected to the main rope 15. 17 moves up and down like a vine.

乗りかご１６及びカウンタウエイト１７の底部には、コンペンロープ１８がコンペンシーブ１９を介して繋がれている。コンペンロープ１８は、メインロープ１５の自重によるアンバランスを解消するためのロープである。 A compen- sion rope 18 is connected to the bottoms of the car 16 and the counterweight 17 via a compensator 19. The compensation rope 18 is a rope for eliminating unbalance due to the weight of the main rope 15.

図１に示すように、本実施形態に係るロープ清掃治具２０は、巻上機１２直下のマシンビーム１３に設置して使用される。図１に示す例では、ロープ清掃治具２０は、巻上機１２及び乗りかご１６間に設置され、例えば乗りかご１６が降下するようにエレベータを動作させた場合にロープ清掃治具２０を上側から下側に通過するメインロープ１５を清掃する。 As shown in FIG. 1, the rope cleaning jig 20 according to the present embodiment is used by being installed on a machine beam 13 directly under the hoisting machine 12. In the example shown in FIG. 1, the rope cleaning jig 20 is installed between the hoisting machine 12 and the car 16. For example, when the elevator is operated so that the car 16 descends, the rope cleaning jig 20 is moved upward. The main rope 15 passing from the bottom to the bottom is cleaned.

次に、図２乃至図４を参照して、ロープ清掃治具２０の構造について説明する。 Next, the structure of the rope cleaning jig 20 will be described with reference to FIGS.

図２はロープ清掃治具２０の構造を示す斜視図である。 FIG. 2 is a perspective view showing the structure of the rope cleaning jig 20.

ロープ清掃治具２０は、清掃対象となる複数本のワイヤロープ１５ａ〜１５ｇ（から構成されるメインロープ１５）の両側から当該複数本のワイヤロープ１５ａ〜１５ｇをまとめて挟み込むように配置される一対の土台２０１ａ，２０１ｂを備える。土台２０１ａ，２０１ｂは、互いに連結されることによってワイヤロープ１５ａ〜１５ｇの各々をロープ清掃治具２０の上側から下側に通過させるための孔部を形成する。土台２０１ａ，２０１ｂは、当該土台２０１ａ，２０１ｂに設けられている留め金具２０２で連結される。 The rope cleaning jig 20 is a pair arranged so as to sandwich the plurality of wire ropes 15a to 15g from both sides of the plurality of wire ropes 15a to 15g (main rope 15 constituted by) to be cleaned. Bases 201a and 201b. The bases 201 a and 201 b are connected to each other to form a hole for allowing each of the wire ropes 15 a to 15 g to pass from the upper side to the lower side of the rope cleaning jig 20. The bases 201a and 201b are connected by a fastener 202 provided on the bases 201a and 201b.

土台２０１ａ，２０１ｂ上には、ワイヤロープ１５ａ〜１５ｇの各々に装着された複数の回転部材２０３ａ〜２０３ｇが配置される。回転部材２０３ａ〜２０３ｇは、ワイヤロープ１５ａ〜１５ｇからグリスを除去するためのグリス除去部材として用いられるものである。これらの回転部材２０３ａ〜２０３ｇの外周には、金属製の締付器具４００ａ〜４００ｇが着脱自在に取り付けられる。 A plurality of rotating members 203a to 203g attached to the wire ropes 15a to 15g are disposed on the bases 201a and 201b. The rotating members 203a to 203g are used as grease removing members for removing grease from the wire ropes 15a to 15g. Metal fastening devices 400a to 400g are detachably attached to the outer peripheries of these rotating members 203a to 203g.

締付器具４００ａ〜４００ｇは、回転部材２０３ａ〜２０３ｇの外周に取り付けられ、回転部材２０３ａ〜２０３ｇをワイヤロープ１５ａ〜１５ｇに圧着して固定するものである。なお、締付器具４００ａ〜４００ｇの構造については後に詳しく説明する。 The fastening devices 400a to 400g are attached to the outer circumferences of the rotating members 203a to 203g, and are fixed by pressing the rotating members 203a to 203g to the wire ropes 15a to 15g. The structure of the fastening devices 400a to 400g will be described in detail later.

ここで、図３を参照して、回転部材２０３ａ〜２０３ｇの構造について説明する。なお、図３においては、便宜的に回転部材２０３ａの構造について説明するが、他の回転部材２０３ｂ〜２０３ｇについても同様の構造である。 Here, the structure of the rotating members 203a to 203g will be described with reference to FIG. In FIG. 3, the structure of the rotating member 203a will be described for convenience, but the other rotating members 203b to 203g have the same structure.

図３に示すように、回転部材２０３ａは、円筒形状をなし、ワイヤロープ１５ａの外周の凹凸形状に合わせて型抜きされた係合孔（孔部）３０１を中心部に有する。回転部材２０３ａは、例えばウレタン樹脂等の弾性体で製造されている。回転部材２０３ａの係合孔３０１と外周との間には切り込み３０２が形成されている。この切り込み３０２の部分を開くことによって、回転部材２０３ａは、ワイヤロープ１５ａに対して回転自在に装着される。また、回転部材２０３ａの外周方向に沿って締付器具４００ａを装着するための溝３０３が形成されている。溝３０３の幅ｗは、締付器具４００ａの幅と略同じである。 As shown in FIG. 3, the rotating member 203 a has a cylindrical shape, and has an engagement hole (hole portion) 301 that is punched in accordance with the uneven shape on the outer periphery of the wire rope 15 a at the center. The rotating member 203a is made of an elastic body such as urethane resin. A notch 302 is formed between the engaging hole 301 and the outer periphery of the rotating member 203a. By opening the notch 302, the rotating member 203a is rotatably attached to the wire rope 15a. Further, a groove 303 for mounting the tightening device 400a is formed along the outer peripheral direction of the rotating member 203a. The width w of the groove 303 is substantially the same as the width of the fastening device 400a.

巻上機１２が駆動されると、ワイヤロープ１５ａは、回転部材２０３ａの係合孔３０１を通過することができる。その際、回転部材２０３ａに締付器具４００ａを装着しておくことで、切り込み３０２が開いてワイヤロープ１５ａから回転部材２０３ａが外れてしまうことを防止できる。 When the hoisting machine 12 is driven, the wire rope 15a can pass through the engagement hole 301 of the rotating member 203a. At this time, by attaching the tightening device 400a to the rotating member 203a, it is possible to prevent the rotating member 203a from being detached from the wire rope 15a due to the opening 302 being opened.

係合孔３０１の径ｄは、ワイヤロープ１５ａの径と略同一であり、回転部材２０３ａがワイヤロープ１５ａに装着された場合に係合孔３０１がワイヤロープ１５ａの外周に密着するように設計されている。このような構造によれば、回転部材２０３ａは、ワイヤロープ１５ａが係合孔３０１を通過する際に、当該ワイヤロープ１５ａの撚りに沿って回転し、当該ワイヤロープ１５ａに付着したグリスを削ぎ取る（除去する）ことができる。 The diameter d of the engagement hole 301 is substantially the same as the diameter of the wire rope 15a, and the engagement hole 301 is designed to be in close contact with the outer periphery of the wire rope 15a when the rotating member 203a is attached to the wire rope 15a. ing. According to such a structure, the rotating member 203a rotates along the twist of the wire rope 15a when the wire rope 15a passes through the engagement hole 301, and scrapes off the grease adhering to the wire rope 15a. (Can be removed).

図２に示すように、回転部材２０３ａ〜２０３ｇは、ワイヤロープ１５ａ〜１５ｇの配列に従って横並びで配置される。このため、図３に示す回転部材２０３ａの外周の径Ｄは、ワイヤロープ１５ａ〜１５ｇ間の間隔に合わせて設計されているものとする。具体的には、回転部材２０３ａの外周の径Ｄは、溝３０３に嵌め込まれる締付器具４００ａの厚みを考慮し、隣接する回転部材２０３ｂ（つまり、回転部材２０３ａが装着されるワイヤロープ１５ａの隣のワイヤロープ１５ｂに装着される回転部材２０３ｂ）と接触しない程度に間隔（例えば、数ミリ）を空けて装着可能なように設計されている。 As shown in FIG. 2, the rotating members 203a to 203g are arranged side by side according to the arrangement of the wire ropes 15a to 15g. For this reason, the diameter D of the outer periphery of the rotation member 203a shown in FIG. 3 shall be designed according to the space | interval between wire ropes 15a-15g. Specifically, the diameter D of the outer periphery of the rotating member 203a takes into account the thickness of the fastening device 400a fitted into the groove 303, and is adjacent to the adjacent rotating member 203b (that is, next to the wire rope 15a to which the rotating member 203a is attached). It is designed so that it can be mounted with an interval (for example, several millimeters) so as not to contact the rotating member 203b) mounted on the wire rope 15b.

また、土台２０１ａの上面の回転部材２０３ａ〜２０３ｇの各々の近傍には、当該回転部材２０３ａ〜２０３ｇによって削ぎ取られたグリスを当該回転部材２０３ａ〜２０３ｇから取り除く（除去する）ためのヘラ部材（スクレーパ）２０４ａ〜２０４ｇが例えば固定用ボルト等を用いて取り付けられている。 A spatula member (scraper) for removing (removing) the grease scraped off by the rotating members 203a to 203g from the rotating members 203a to 203g is provided near each of the rotating members 203a to 203g on the upper surface of the base 201a. ) 204a to 204g are attached using, for example, fixing bolts.

土台２０１ａの側面には、例えば断面がコの字形状のグリス回収部材２０５が固定用ボルト等を用いて取り付けられている。ヘラ部材２０４ａ〜２０４ｇは、回転部材２０３ａ〜２０３ｇとグリス回収部材２０５との間に取り付けられる。これにより、ヘラ部材２０４ａ〜２０４ｇは、各回転部材２０３ａ〜２０３ｇの回転に応じて当該回転部材２０３ａ〜２０３ｇ（の上面）からグリスを取り除き、当該グリスをグリス回収部材２０５に流し込む。 For example, a grease collecting member 205 having a U-shaped cross section is attached to the side surface of the base 201a using a fixing bolt or the like. The spatula members 204a to 204g are attached between the rotating members 203a to 203g and the grease collecting member 205.

第５部材４０５のリング外周面側から長穴４５４を介して第２部材４０２のネジ穴４２４（図１０参照）にいもねじ等の留め具４２５を挿入することで、サイズ調整後の状態を固定できる。 The state after size adjustment is fixed by inserting a fastener 425 such as a potato screw into the screw hole 424 (see FIG. 10) of the second member 402 from the ring outer peripheral surface side of the fifth member 405 through the elongated hole 454. it can.

ここで、図１９および図２０を参照して、第１の実施形態における締付器具４００ａをリング状に閉じるときの手順について説明する。 Here, with reference to FIG. 19 and FIG. 20, a procedure for closing the fastening device 400a in the first embodiment in a ring shape will be described.

まず、図１９に示すように、連結された第１部材４０１と第２部材４０２と第５部材４０５を第４部材４０４の一端部に設けられた固定金具４４１を支点にしてリング内側に向けて回動する。そして、第１部材４０１に形成された係合用の爪部４１２ａ，４１２ｂを第３部材４０３に設けられた固定金具４３４に引っ掛ける。 First, as shown in FIG. 19, the connected first member 401, second member 402, and fifth member 405 are directed toward the inner side of the ring with a fixing bracket 441 provided at one end of the fourth member 404 as a fulcrum. Rotate. Then, the engaging claws 412 a and 412 b formed on the first member 401 are hooked on the fixing bracket 434 provided on the third member 403.

次に、図２０に示すように、第１部材４０１の押込み部４１１を第３部材４０３の開口部４３２に向けて回動して第１部材４０１を開口部４３２に収納してリング状にする。上述したように、このときに六角レンチ４１７を用いてロック用金具４１５を９０度回転させれば、締付器具４００ａのリング状態がロックされる（図１５参照）。 Next, as shown in FIG. 20, the pushing portion 411 of the first member 401 is rotated toward the opening 432 of the third member 403 so that the first member 401 is accommodated in the opening 432 and formed into a ring shape. . As described above, if the lock fitting 415 is rotated 90 degrees using the hexagon wrench 417 at this time, the ring state of the tightening device 400a is locked (see FIG. 15).

次に、本実施形態に係るロープ清掃治具２０を使用してメインロープ１５を清掃する場合の動作について説明する。 Next, an operation when the main rope 15 is cleaned using the rope cleaning jig 20 according to the present embodiment will be described.

メインロープ１５（を構成する複数本のワイヤロープ１５ａ〜１５ｇ）を清掃する場合、乗りかご１６を最上階に移動させておき、ロープ清掃治具２０をマシンビーム１３に設置する。 When cleaning the main rope 15 (a plurality of wire ropes 15 a to 15 g constituting the main rope 15), the car 16 is moved to the top floor, and the rope cleaning jig 20 is installed on the machine beam 13.

この場合、例えば図２１に示すように、土台２０１ａ，２０１ｂによって形成される孔部にワイヤロープ１５ａ〜１５ｇが位置するように、土台２０１ａ，２０１ｂをワイヤロープ１５ａ〜１５ｇの両側から挟み込むようにマシンビーム１３に載置して、土台２０１ａ，２０１ｂを留め金具２０２で連結する。 In this case, for example, as shown in FIG. 21, the machine is such that the bases 201 a and 201 b are sandwiched from both sides of the wire ropes 15 a to 15 g so that the wire ropes 15 a to 15 g are positioned in the holes formed by the bases 201 a and 201 b. It mounts on the beam 13 and the bases 201a and 201b are connected by the fasteners 202.

ここで、ワイヤロープ１５ａ〜１５ｇの各々には、回転部材２０３ａ〜２０３ｇが装着される。そして、これらの回転部材２０３ａ〜２０３ｇに対して、締付器具４００ａ〜４００ｇが取り付けられる。 Here, rotating members 203a to 203g are attached to the wire ropes 15a to 15g, respectively. And tightening instrument 400a-400g is attached with respect to these rotation members 203a-203g.

締付器具４００ａ〜４００ｇの取り付け方法について、締付器具４００ａを例にして説明すると、締付器具４００ａを開いた状態にして（図１４参照）、回転部材２０３ａの外周に腕時計のバンドのように巻き付ける。そして、図１９および図２０で説明したように、第１部材４０１に形成された係合用の爪部４１２ａ，４１２ｂを第３部材４０３に設けられた固定金具４３４に引っ掛け、第１部材４０１の押込み部４１１を第３部材４０３の開口部４３２に向けて回動して、当該第１部材４０１を開口部４３２に収納してリング状にする。 The method of attaching the fastening devices 400a to 400g will be described by taking the fastening device 400a as an example. The fastening device 400a is opened (see FIG. 14), and the outer periphery of the rotating member 203a is like a wristwatch band. Wrap. 19 and FIG. 20, the engaging claws 412a and 412b formed on the first member 401 are hooked on the fixing bracket 434 provided on the third member 403, and the first member 401 is pushed. The part 411 is rotated toward the opening part 432 of the third member 403 so that the first member 401 is accommodated in the opening part 432 and formed into a ring shape.

締付器具４００ａをリング状にした後、図１５に示したように、六角レンチ４１７を使ってロック用金具４１５を９０度回転させ、突起部４１５ａ，４１５ｂを凹部４３３ａ，４３３ｂに係合させれば、そのリング状態がロックされる。これにより、回転部材２０３ａが締付器具４００ａによって外周から締め付けられ、ワイヤロープ１５ａに圧着して固定される。 After the fastening device 400a is made into a ring shape, the lock fitting 415 is rotated 90 degrees using a hexagon wrench 417 as shown in FIG. 15, and the protrusions 415a and 415b are engaged with the recesses 433a and 433b. The ring state is locked. Thereby, the rotating member 203a is fastened from the outer periphery by the fastening device 400a, and is fixed by being crimped to the wire rope 15a.

なお、締付器具４００ａはワイヤロープ１５ａのサイズ（太さ）に合ったものが使用されるが、経年変化などで多少の太さが変わってくる。したがって、図１７および図１８で説明した調整機構を使って、現在のロープサイズに合わせて回転部材２０３ａを適切な力で締め付けられるように締付器具４００ａの円周サイズを微調整しておくことが好ましい。 In addition, although the thing suitable for the size (thickness) of the wire rope 15a is used for the fastening instrument 400a, some thickness changes with secular change etc. Therefore, by using the adjustment mechanism described in FIGS. 17 and 18, the circumferential size of the tightening device 400a is finely adjusted so that the rotating member 203a can be tightened with an appropriate force according to the current rope size. Is preferred.

他のワイヤロープ１５ｂ〜１５ｇに対して同様である。すなわち、ワイヤロープ１５ｂ〜１５ｇの軸周りに装着された回転部材２０３ｂ〜２０３ｇのそれぞれに締付器具４００ｂ〜４００ｇを取り付け、回転部材２０３ｂ〜２０３ｇを外周から詰め付けてワイヤロープ１５ｂ〜１５ｇに圧着して固定する。 The same applies to the other wire ropes 15b to 15g. That is, the fastening devices 400b to 400g are attached to the rotating members 203b to 203g mounted around the shafts of the wire ropes 15b to 15g, and the rotating members 203b to 203g are packed from the outer periphery and are crimped to the wire ropes 15b to 15g. And fix.

なお、例えばヘラ部材２０４ａ〜２０４ｇによって回転部材２０３ａ〜２０３ｇをワイヤロープ１５ａ〜１５ｇに装着することが困難である場合には、土台２０１ａ，２０１ｂを連結する前に回転部材２０３ａ〜２０３ｇをワイヤロープ１５ａ〜１５ｇに装着して締付器具４００ａ〜４００ｇで固定しておくことでも良い。 For example, when it is difficult to attach the rotating members 203a to 203g to the wire ropes 15a to 15g by the spatula members 204a to 204g, the rotating members 203a to 203g are connected to the wire rope 15a before connecting the bases 201a and 201b. It may be attached to ˜15 g and fixed with the fastening devices 400 a to 400 g.

締付器具４００ａ〜４００ｇの取り付けは、針金などで回転部材２０３ａ〜２０３ｇを締め付ける方法に比べて非常に簡単であり、時間もかからない。さらに、締付器具４００ａ〜４００ｇは、リンク状に閉じているときに各部材４０１〜４０５がリング外周径内に収まっているので、隣接するロープあるいは回転部材に干渉することもない。 The attachment of the fastening devices 400a to 400g is much simpler and takes less time than the method of fastening the rotating members 203a to 203g with a wire or the like. Furthermore, since each member 401-405 is settled in the ring outer periphery diameter when the fastening instruments 400a-400g are closed in a link shape, they do not interfere with an adjacent rope or rotating member.

この様子を図２２および図２３に示す。なお、ここでは便宜的に４本のワイヤロープ１５ａ〜１５ｄを例にして説明する。図２２は締付器具４００ａ〜４００ｄを用いた場合のサイズとロープ間ピッチとの関係を示す図である。図２３は一般的なホースバンド５００ａ〜５００ｄを用いた場合のサイズとロープ間ピッチとの関係を示す図である。 This situation is shown in FIG. 22 and FIG. Here, for convenience, four wire ropes 15a to 15d will be described as an example. FIG. 22 is a diagram showing the relationship between the size and the pitch between ropes when the fastening devices 400a to 400d are used. FIG. 23 is a diagram showing the relationship between the size and the pitch between ropes when general hose bands 500a to 500d are used.

ワイヤロープ１５ａ〜１５ｄのそれぞれに回転部材２０３ａ〜２０３ｄが取り付けられている。ここで、図２２に示すように、ロープ間ピッチをＬとすると、Ｌ／２以下の間隔で回転部材２０３ａ〜２０３ｄの外周に締付器具４００ａ〜４００ｄに取り付けることが可能である。一方、図２３に示すように、ホースバンド５００ａ〜５００ｄには、ボルトなどの固定金具５０１ａ〜５０１ｄがバンドの外周上に存在する。このため、ホースバンド５００ａ〜５００ｄを回転部材２０３ａ〜２０３ｄに取り付けた後に固定金具５０１ａ〜５０１ｄを締める作業が面倒である。さらに点線で示すように、固定金具５０１ａ〜５０１ｄの動線５０２ａ〜５０２ｄがＬ／２を越えて、互いに干渉してしまうことがある。 Rotating members 203a to 203d are attached to the wire ropes 15a to 15d, respectively. Here, as shown in FIG. 22, when the pitch between the ropes is L, the fastening devices 400a to 400d can be attached to the outer periphery of the rotating members 203a to 203d at intervals of L / 2 or less. On the other hand, as shown in FIG. 23, in the hose bands 500a to 500d, fixing brackets 501a to 501d such as bolts exist on the outer periphery of the band. For this reason, it is troublesome to tighten the fixing brackets 501a to 501d after the hose bands 500a to 500d are attached to the rotating members 203a to 203d. Furthermore, as indicated by the dotted lines, the flow lines 502a to 502d of the fixtures 501a to 501d may exceed L / 2 and interfere with each other.

このように、締付器具４００ａ〜４００ｄを用いれば、ホースバンド５００ａ〜５００ｄを適用できないロープ間ピッチの狭いエレベータでも適用することができる。 In this way, if the fastening devices 400a to 400d are used, it is possible to apply even an elevator with a narrow pitch between ropes to which the hose bands 500a to 500d cannot be applied.

７本のワイヤロープ１５ａ〜１５ｇに対して、回転部材２０３ａ〜２０３ｇと締付器具４００ａ〜４００ｇを装着した状態が図２であり、これでロープ清掃治具２０の設置が完了する。 Against seven wire rope 15a-15g, state the rotating member 203a~203g and fastening instrument 400A～400 g wearing it is 2, which in the installation of the rope cleaning fixture 20 is completed.

ロープ清掃治具２０の設置後、エレベータの乗りかご１６を動作させる。具体的には、ワイヤロープ１５ａ〜１５ｇに装着された回転部材２０３ａ〜２０３ｇがロープ清掃治具２０の土台２０１ａ，２０１ｂに押し付けられる方向（すなわち、最上階から最下階の方向）に乗りかご１６を移動させる。 After the rope cleaning jig 20 is installed, the elevator car 16 is operated. Specifically, the car 16 in the direction in which the rotating members 203a to 203g attached to the wire ropes 15a to 15g are pressed against the bases 201a and 201b of the rope cleaning jig 20 (that is, the direction from the top floor to the bottom floor). Move.

ロープ清掃治具２０がマシンビーム１３に設置されているため、乗りかご１６の最上階から最下階への移動に応じて、ワイヤロープ１５ａ〜１５ｇの各々は、ワイヤロープ１５ａ〜１５ｇに対して装着された回転部材２０３ａ〜２０３ｇの各々が有する係合孔３０１を通過する。この際、回転部材２０３ａ〜２０３ｇは、ロープ清掃治具２０の土台２０１ａ，２０１ｂに当接した（押し付けられた）状態で回転する。回転部材２０３ａ〜２０３ｇの各々は、上記したようにワイヤロープ１５ａ〜１５ｇの外周に密着した状態で回転するため、当該回転しながら当該ワイヤロープ１５ａ〜１５ｇに付着したグリスを掻き出す（削ぎ取る）ことができる。 Since the rope cleaning jig 20 is installed on the machine beam 13, each of the wire ropes 15 a to 15 g corresponds to the wire ropes 15 a to 15 g according to the movement of the car 16 from the top floor to the bottom floor. It passes through the engagement hole 301 included in each of the mounted rotating members 203a to 203g. At this time, the rotating members 203a to 203g rotate in a state of being in contact (pressed) with the bases 201a and 201b of the rope cleaning jig 20. Since each of the rotating members 203a to 203g rotates in a state of being in close contact with the outer circumferences of the wire ropes 15a to 15g as described above, the grease attached to the wire ropes 15a to 15g is scraped off (scraped) while rotating. Can do.

回転部材２０３ａ〜２０３ｇによって掻き出されたグリスは、当該回転部材２０３ａ〜２０３ｇの上面に堆積する。上述したように回転部材２０３ａ〜２０３ｇの近傍にはヘラ部材２０４ａ〜２０４ｇが取り付けられているため、回転部材２０３ａ〜２０３ｇの上面に堆積したグリスは、当該回転部材２０３ａ〜２０３ｇの回転に応じて当該ヘラ部材２０４ａ〜２０４ｇによって取り除かれる。ヘラ部材２０４ａ〜２０４ｇによって除去されたグリスは、グリス回収部材２０５において回収される。 The grease scraped by the rotating members 203a to 203g accumulates on the upper surfaces of the rotating members 203a to 203g. As described above, since the spatula members 204a to 204g are attached in the vicinity of the rotating members 203a to 203g, the grease deposited on the upper surfaces of the rotating members 203a to 203g corresponds to the rotation of the rotating members 203a to 203g. The spatula members 204a to 204g are removed. The grease removed by the spatula members 204a to 204g is collected by the grease collecting member 205.

このように第１の実施形態によれば、ワイヤロープ１５ａ〜１５ｇに装着された清掃用の回転部材２０３ａ〜２０３ｇを固定する際に、締付器具４００ａ〜４００ｇを用いることで、隣接するロープ間で干渉せずに回転部材２０３ａ〜２０３ｇの外周から締め付けてワイヤロープ１５ａ〜１５ｇに固定することができる。 According to the first embodiment, when fixing the rotation member 203a~203g for cleaning that is mounted to the wire ropes 15a-15g, by using a tightening tool 400A～400 g, adjacent ropes It can clamp | tighten from the outer periphery of rotating member 203a-203g, without interfering between, and can be fixed to wire rope 15a-15g.

ここで、締付器具４００ａ〜４００ｇは、複数の部材４０１〜４０５が回動自在に連結されたものであり、腕時計のバンドのようにリング状に閉じて止めるだけの簡単な構造である。したがって、針金やホースバンドなどを使うときのような面倒な作業や力を必要とせずに、回転部材２０３ａ〜２０３ｇに簡単に取り付けることができ、作業時間の大幅な短縮化を図れると共に作業員の負担を軽減できる。 Here, tightening instrument 400A～400 g is for a plurality of members 401 to 405 are rotatably connected to a simple structure of just stopping closed in a ring shape like a wristwatch band. Therefore, it can be easily attached to the rotating members 203a to 203g without requiring the troublesome work and force required when using a wire, a hose band, etc., and the working time can be greatly shortened and the operator's The burden can be reduced.

なお、本実施形態においては、図１に示すようにロープ清掃治具２０が巻上機１２及び乗りかご１６間でメインロープ１５を清掃するものとして説明したが、ロープ清掃治具２０は、例えば図２４に示すように巻上機１２及びカウンタウエイト１７間でメインロープ１５を清掃するように設置されても良い。この場合には、乗りかご１６を最下階から最上階に移動させることによって同様にメインロープ１５を清掃することができる。 In the present embodiment, the rope cleaning jig 20 is described as cleaning the main rope 15 between the hoist 12 and the car 16 as shown in FIG. As shown in FIG. 24, the main rope 15 may be installed between the hoisting machine 12 and the counterweight 17. In this case, the main rope 15 can be similarly cleaned by moving the car 16 from the lowermost floor to the uppermost floor.

さらに、例えば図２５および図２６に示すように、コンペンシーブ１９の近くにロープ清掃治具２０を設置してコンペンロープ１８を清掃することも可能である。 Further, for example, as shown in FIGS. 25 and 26, it is possible to clean the compensation rope 18 by installing a rope cleaning jig 20 near the compensation sheave 19.

また、本実施形態に係るロープ清掃治具２０においては、複数の回転部材２０３ａ〜２０３ｇの回転を補助するための図示せぬ回転補助機構が設けられていても良い。回転補助機構は、例えばボール及び当該ボールを回転自在に支持する支持部材とから構成される。このような回転補助機構を、ワイヤロープ１５ａ〜１５ｇに装着された回転部材２０３ａ〜２０３ｇの各々を支持するように、土台２０１ａ，２０１ｂに設けることによって、当該回転部材２０３ａ〜２０３ｇを回転補助機構のボールの上でスムーズに回転させることが可能となる。 In addition, in the rope cleaning jig 20 according to the present embodiment, a rotation assist mechanism (not shown) for assisting the rotation of the plurality of rotation members 203a to 203g may be provided. The rotation assist mechanism includes, for example, a ball and a support member that rotatably supports the ball. By providing such a rotation assist mechanism on the bases 201a and 201b so as to support each of the rotation members 203a to 203g attached to the wire ropes 15a to 15g, the rotation members 203a to 203g of the rotation assist mechanism are provided. It can be smoothly rotated on the ball.
