マシンベース9、巻上機6及びそらせ車7を機械室2内に設置するときには、マシンベース9を2本の機械台8間に固定した後に巻上機6及びそらせ車7をマシンベース9に取り付けてもよいし、巻上機6及びそらせ車7を予め取り付けておいたマシンベース9を2本の機械台8間に固定してもよい。また、かご側主索固定装置13及び釣合おもり側主索固定装置14を機械室2内に設置するときには、一対の渡し梁21を2本の機械台8間に固定した後に綱止構造体22を渡し梁21に固定してもよいし、綱止構造体22を予め固定しておいた一対の渡し梁21を2本の機械台8間に固定してもよい(機器設置工程)。   When the machine base 9, the hoisting machine 6 and the deflecting wheel 7 are installed in the machine room 2, the machine base 9 is fixed between the two machine bases 8, and then the hoisting machine 6 and the deflecting wheel 7 are attached to the machine base 9. The machine base 9 to which the hoisting machine 6 and the deflecting wheel 7 are attached in advance may be fixed between the two machine bases 8. Further, when the car-side main rope fixing device 13 and the counterweight-side main rope fixing device 14 are installed in the machine room 2, after the pair of transfer beams 21 are fixed between the two machine bases 8, 22 may be fixed to the transfer beam 21, or a pair of transfer beams 21 to which the pawl structure 22 is fixed in advance may be fixed between the two machine bases 8 (equipment installation step).

この後、かご吊り車11、駆動綱車5、そらせ車7及び釣合おもり吊り車12に新規の主索10を巻き掛けるとともに、機械室2内の2本の機械台8に設置したかご側主索固定装置13の綱止梁24の綱止部24aに主索10の一端部を接続し、機械室2内の2本の機械台8に設置したかご側主索固定装置13の綱止梁24の綱止部24aに主索10の他端部を接続する(主索接続工程)。   Thereafter, a new main rope 10 is wound around the car suspension wheel 11, the driving sheave 5, the deflecting wheel 7 and the counterweight suspension wheel 12, and the car side installed on the two machine bases 8 in the machine room 2. One end of the main rope 10 is connected to the rope stopping portion 24a of the rope fixing beam 24 of the main rope fixing device 13, and the rope anchoring of the car side main rope fixing device 13 installed on the two machine bases 8 in the machine room 2 The other end portion of the main rope 10 is connected to the rope stopping portion 24a of the beam 24 (main rope connection step).

この後、かご3及び釣合おもり4を支持する支持具を取り外すことにより、かご3及び釣合おもり4を主索10で吊り下げる(吊り下げ工程)。このようにして、かご3及び釣合おもり4の主索10による吊り下げ方式を1:1から2:1に変更する。   Then, the cage 3 and the counterweight 4 are suspended by the main rope 10 by removing the support that supports the car 3 and the counterweight 4 (hanging process). In this way, the suspension method of the car 3 and the counterweight 4 by the main rope 10 is changed from 1: 1 to 2: 1.

このようなかご側主索固定装置13及び釣合おもり側主索固定装置14では、渡し梁21が既設の2本の機械台8間に渡して固定され、主索10が接続された綱止梁24を含む綱止構造体22が渡し梁21に固定されているので、かご3及び釣合おもり4の主索10による吊り下げ方式を1:1から2:1に変更する改修工事を行うときに、2本の機械台8を利用するだけで、かご側主索固定装置13及び釣合おもり側主索固定装置14を機械室2内に設置することができ、機械台8と同じ長さを持つ綱止用のビームを機械室2内に新たに設置する必要がなくなる。これにより、綱止用のビームの部品コストをなくすことができ、エレベータの改修工事にかかるコストの低減化を図ることができる。また、長尺部材である綱止用のビームを機械室2内に設置する必要がなくなるので、かご側主索固定装置13及び釣合おもり側主索固定装置14を機械室2内に設置する手間を軽減することができ、エレベータの改修工事の手間の軽減化を図ることもできる。   In such a car-side main rope fixing device 13 and a counterweight-side main rope fixing device 14, the crossing beam 21 is fixed between two existing machine bases 8 and the main rope 10 is connected. Since the anchoring structure 22 including the beam 24 is fixed to the crossing beam 21, the rehabilitation work is performed to change the suspension method of the car 3 and the counterweight 4 by the main rope 10 from 1: 1 to 2: 1. Sometimes, the car-side main rope fixing device 13 and the counterweight-side main rope fixing device 14 can be installed in the machine room 2 by using only two machine bases 8, and have the same length as the machine base 8. Therefore, it is not necessary to newly install a beam for securing the rope in the machine room 2. As a result, it is possible to eliminate the cost of parts of the beam for fastening the rope, and it is possible to reduce the cost required for the repair work of the elevator. Further, since it is not necessary to install a beam for tightening which is a long member in the machine room 2, the car-side main rope fixing device 13 and the counterweight-side main rope fixing device 14 are installed in the machine room 2. It is possible to reduce the time and effort of the elevator repair work.

また、綱止構造体22は、上から見たときに、2本の機械台8間に配置されているので、かご3及び釣合おもり4を吊り下げる主索10を2本の機械台8間の空間を通して綱止構造体22の綱止梁24に接続することができる。これにより、かご側主索固定装置13及び釣合おもり側主索固定装置14のそれぞれの上から見たときの設置スペースを2本の機械台8間の範囲に収めることができ、機械室2内に設置される機器のスペースの縮小化を図ることができる。   Further, since the leash structure 22 is arranged between the two machine bases 8 when viewed from above, the main rope 10 for suspending the car 3 and the counterweight 4 is attached to the two machine bases 8. It is possible to connect to the toe beam 24 of the toe structure 22 through the space therebetween. Thus, the installation space when viewed from above each of the car-side main rope fixing device 13 and the counterweight-side main rope fixing device 14 can be accommodated in the range between the two machine bases 8. It is possible to reduce the space of equipment installed inside.

また、綱止構造体22は渡し梁21に固定された取付台23を有し、綱止梁24は渡し梁21の上面よりも高い位置で取付台23に固定されているので、綱止梁24に接続された主索10の一端部及び他端部の位置を、渡し梁21の上面よりも高い位置にすることができる。これにより、主索10の傾きを鉛直方向に近づけることができ、かご3及び釣合おもり4の主索10による吊り下げ調整作業を容易にすることができる。   In addition, the toe structure 22 has a mounting base 23 fixed to the cross beam 21 and the toe beam 24 is fixed to the mounting base 23 at a position higher than the upper surface of the cross beam 21. The positions of the one end and the other end of the main rope 10 connected to 24 can be higher than the upper surface of the cross beam 21. Thereby, the inclination of the main rope 10 can be brought close to the vertical direction, and the suspension adjustment work by the main rope 10 of the car 3 and the counterweight 4 can be facilitated.

また、渡し梁21は、締結具25によって2本の機械台8に固定されているので、機械室2内における現地溶接作業を不要にすることができる。これにより、エレベータの改修工事の手間をさらに軽減することができる。   Further, since the cross beam 21 is fixed to the two machine bases 8 by the fasteners 25, the field welding work in the machine room 2 can be made unnecessary. Thereby, the effort of the repair work of an elevator can further be reduced.

また、このようなエレベータの改修方法では、既設の2本の機械台8間に渡して固定された渡し梁21と、渡し梁21に固定された綱止構造体22とをそれぞれ有するかご側主索固定装置13及び釣合おもり側主索固定装置14を機械室2内に設置するので、2本の機械台8を利用するだけで、かご側主索固定装置13及び釣合おもり側主索固定装置14を機械室2内に設置することができ、綱止用のビームの部品コストをなくすことができる。これにより、エレベータの改修工事にかかるコストの低減化を図ることができる。また、長尺部材である綱止用のビームを機械室2内に設置する必要がなくなるので、エレベータの改修工事の手間の軽減化を図ることもできる。   Further, in such an elevator renovation method, the car side main unit having the crossing beam 21 fixed between the two existing machine bases 8 and the toe structure 22 fixed to the crossing beam 21 is provided. Since the rope fixing device 13 and the counterweight side main rope fixing device 14 are installed in the machine room 2, the car side main rope fixing device 13 and the counterweight side main rope can be simply used by using the two machine bases 8. The fixing device 14 can be installed in the machine room 2, and the cost of parts of the beam for tightening can be eliminated. Thereby, the cost concerning the repair work of an elevator can be reduced. In addition, since it is not necessary to install a beam for tightening, which is a long member, in the machine room 2, it is possible to reduce the labor for repair work of the elevator.

なお、上記の例では、渡し梁21に固定された取付台23に綱止梁24が固定されているが、取付台23をなくして、渡し梁21に綱止梁24を直接固定してもよい。   In the above example, the toe beam 24 is fixed to the mounting base 23 fixed to the cross beam 21. However, even if the mounting base 23 is eliminated and the toe beam 24 is directly fixed to the cross beam 21, Good.

また、上記の例では、一対の渡し梁21が2本の機械台8間に渡して固定され、綱止構造体22が一対の渡し梁21間に固定されているが、かご側主索固定装置13及び釣合おもり側主索固定装置14の強度を確保することができるのであれば、1つの渡し梁21を2本の機械台8間に渡して固定し、渡し梁21に綱止構造体22を片持ちで固定してもよい。   Further, in the above example, the pair of cross beams 21 are fixed between the two machine bases 8, and the toe structure 22 is fixed between the pair of cross beams 21. If the strength of the device 13 and the counterweight-side main rope fixing device 14 can be ensured, one crossing beam 21 is fixed between the two machine bases 8 and fixed to the crossing beam 21. The body 22 may be fixed in a cantilever manner.

また、上記の例では、主索10の一端部及び他端部が互いに異なる綱止梁24に個別に接続されているが、主索固定装置の共通の綱止梁24に主索10の一端部及び他端部を接続してもよい。この場合、主索固定装置の構成は釣合おもり側主索固定装置14と同様の構成とされ、機械室2内に設置される主索固定装置の数は1つとされる。   Moreover, in the above example, one end and the other end of the main rope 10 are individually connected to different rope anchors 24, but one end of the main rope 10 is connected to a common rope anchor 24 of the main rope fixing device. And the other end may be connected. In this case, the configuration of the main rope fixing device is the same as that of the counterweight side main rope fixing device 14, and the number of main rope fixing devices installed in the machine room 2 is one.

また、上記の例では、機械台8、渡し梁21、取付台23、綱止梁24間の固定が締結具25によって行われているが、機械台8、渡し梁21、取付台23、綱止梁24間の少なくともいずれかの固定を溶接によって行ってもよい。   In the above example, the machine base 8, the crossing beam 21, the mounting base 23, and the rope fixing beam 24 are fixed by the fasteners 25, but the machine base 8, the crossing beam 21, the mounting base 23, the steel rope At least one of the fixing between the stop beams 24 may be performed by welding.

また、上記の例では、主索10の一端部及び他端部がいずれも機械室2内で接続されたエレベータが改修後のエレベータとなっているが、主索10の一端部及び他端部のいずれか一方が機械室2内で接続され、主索10の一端部及び他端部のいずれか他方がかご3及び釣合おもり4のいずれかに接続されたエレベータを改修後のエレベータとしてもよい。即ち、主索10の一端部及び他端部の少なくともいずれかが機械室2内で接続されたエレベータであれば、改修後のエレベータとして適用されることができる。また、改修後のエレベータにおけるかご3及び釣合おもり4の主索10による吊り下げ方式が2:1とされているが、改修後のエレベータにおけるかご3及び釣合おもり4の主索10による吊り下げ方式を4:1等としてもよい。   In the above example, the elevator in which one end portion and the other end portion of the main rope 10 are both connected in the machine room 2 is an elevator after repair. As an elevator after refurbishment, an elevator in which one of these is connected in the machine room 2 and one of the one end and the other end of the main rope 10 is connected to either the car 3 or the counterweight 4 Good. That is, as long as at least one of the one end and the other end of the main rope 10 is connected in the machine room 2, it can be applied as an elevator after refurbishment. Moreover, although the suspension method by the main rope 10 of the cage 3 and the counterweight 4 in the elevator after the modification is 2: 1, the elevator 3 and the counterweight 4 in the elevator after the modification are suspended by the main rope 10. The lowering method may be 4: 1 or the like.
