Description

エレベータ装置及びその改修方法Elevator apparatus and repair method thereof
　この発明は、昇降路内に調速機が設けられているエレベータ装置、及び既設の非常止め装置を流用して新たな調速機を設置するエレベータ装置の改修方法に関するものである。 The present invention relates to an elevator apparatus in which a speed governor is provided in a hoistway, and a method for repairing an elevator apparatus in which a new speed governor is installed by diverting an existing emergency stop device.
　従来のエレベータの安全装置では、かごの下部に三角レバーが搭載されている。三角レバーには、接続部材を介して非常止め作動レバーが接続されている。接続部材の長さは、引上機構部のかご床に対する取付位置に応じて設定されている。これにより、引上機構部のかご床に対する取付位置が、かごの奥行方向に調整可能となっている（例えば、特許文献１参照）。 In the conventional elevator safety device, a triangular lever is mounted at the bottom of the car. An emergency stop operating lever is connected to the triangular lever via a connecting member. The length of the connecting member is set according to the mounting position of the lifting mechanism portion with respect to the car floor. Thereby, the attachment position with respect to the car floor of a raising mechanism part can be adjusted to the depth direction of a car (for example, refer patent document 1).

　例えば、調速機を持たない油圧エレベータを、既設機器（かご及びガイドレール等）を残して調速機付きの機械室レスエレベータに改修する場合、レイアウトの問題等から既設の非常止め装置を流用できず、新たな非常止め装置に取り替える必要があった。このため、非常止め装置を新たに設計、製作する必要があり、コストが高くなる。また、改修工事の際、既設の非常止め装置を撤去するためにかご室周りの種々の機器を一旦撤去した上で、新たな非常止め装置を取り付けた後に、撤去した機器を再度据え付けて調整し直す必要があり、改修工期が大幅に長くなる。 For example, when refurbishing a hydraulic elevator without a governor to a machine room-less elevator with a governor, leaving the existing equipment (cage, guide rail, etc.), divert the existing emergency stop device due to layout problems. It was not possible to replace it with a new emergency stop device. For this reason, it is necessary to newly design and manufacture the emergency stop device, which increases the cost. Also, during the renovation work, once the various equipment around the cab is removed to remove the existing emergency stop device, a new emergency stop device is installed, and then the removed device is re-installed and adjusted. It is necessary to fix it, and the repair period is significantly increased.
　これに対して、従来のエレベータの安全装置では、引上機構部のかご床に対する取付位置が、非常止め作動レバーの軸方向に直角な方向へのみ調整可能であり、非常止め作動レバーの軸方向へは調整できない。このため、改修工事において、既設の非常止め装置の位置及び昇降路機器の位置によっては、既設の非常止め装置を流用しつつ新たに調速機を設置することが困難な場合がある。 On the other hand, in the conventional elevator safety device, the mounting position of the lifting mechanism relative to the car floor can be adjusted only in the direction perpendicular to the axial direction of the emergency stop operating lever. Cannot be adjusted. For this reason, in the renovation work, depending on the position of the existing emergency stop device and the position of the hoistway device, it may be difficult to install a new speed governor while diverting the existing emergency stop device.
　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、既設の非常止め装置を流用しつつ新たな調速機を容易に設置することができるエレベータ装置及びその改修方法を得ることを目的とする。 The present invention has been made to solve the above-described problems, and provides an elevator apparatus that can easily install a new speed governor while diverting an existing emergency stop device and a method for repairing the same.

　また、この発明に係るエレベータ装置の改修方法は、既設のかごの下部に追加連結装置フレームを固定する工程、追加連結装置フレームに回転自在に保持されている追加延長軸の第１の端部を、引上レバー連結具を用いて既設の非常止め装置の引上レバーに連結する工程、追加延長軸の第２の端部に追加レバーを連結する工程、昇降路内に調速機を設置するとともに、調速機の調速機シーブに調速機ロープを巻き掛ける工程、及び追加レバーを、調速機ロープ連結具を用いて調速機ロープに連結する工程を含む。 An elevator apparatus according to the present invention is mounted on a car, a car guide rail that guides the raising and lowering of the car, and a car, and has an up lever and a up lever shaft that is a rotation axis of the up lever. And an emergency stop device that holds the car guide rail and stops the car to an emergency stop, a governor rope that circulates as the car moves up and down, and a governor sheave around which the governor rope is wound It has a speed governor that detects the excessive speed of the car and activates the emergency stop device, and the car is equipped with an additional connecting device that connects the lifting lever shaft and the speed governor rope.

Further, the method for repairing an elevator apparatus according to the present invention includes a step of fixing an additional connecting device frame to a lower portion of an existing car, and a first end portion of the additional extension shaft rotatably held by the additional connecting device frame. , A step of connecting to the pull-up lever of the existing emergency stop device using the pull-up lever connector, a step of connecting the additional lever to the second end of the additional extension shaft, and a governor is installed in the hoistway And a step of winding the governor rope around the governor sheave of the governor, and a step of connecting the additional lever to the governor rope using the governor rope connector.
　この発明のエレベータ装置及びその改修方法は、引上レバー連結具、追加延長軸、追加レバー及び調速機ロープ連結具を介して、引上レバー軸と調速機ロープとを連結するので、既設の引上レバーの真上に調速機を設置できない場合でも、既設の非常止め装置を流用しつつ新たな調速機を容易に設置することができる。 In the elevator apparatus and the repair method thereof according to the present invention, the lifting lever shaft and the governor rope are coupled via the lifting lever connector, the additional extension shaft, the additional lever, and the governor rope connector.

　次に、動作について説明する。例えば懸架体の破断等により、かご１の下降速度が調速機１０に設定された過大速度に達すると、調速機１０により調速機ロープ１２の移動が停止される。これにより、下降するかご１に対して引上棒１９が引き上げられ、追加レバー１８が追加延長軸１６を中心として回転される。そして、追加レバー１８の回転が追加延長軸１６及び引上レバー連結具１７を介して引上レバー８ａ及び引上レバー軸９に伝達され、非常止め装置７が作動する。 Next, the operation will be described. For example, when the descending speed of the car 1 reaches an excessive speed set in the governor 10 due to breakage of the suspension body, the governor 10 stops the movement of the governor rope 12. As a result, the pulling bar 19 is pulled up with respect to the descending car 1, and the additional lever 18 is rotated about the additional extension shaft 16. Then, the rotation of the additional lever 18 is transmitted to the lifting lever 8a and the lifting lever shaft 9 via the additional extension shaft 16 and the lifting lever connector 17, and the emergency stop device 7 operates.
　このようなエレベータ装置では、追加延長軸１６及び追加レバー１８を有する追加連結装置１４を用いて引上レバー軸９と調速機ロープ１２とが連結されているので、真上から見て、既設の非常止め装置７から引上レバー軸９の軸方向に離れた位置に調速機１０を設置することができる。即ち、既設の引上レバー８ａの真上に調速機１０を設置できない場合でも、既設の非常止め装置７を流用しつつ新たな調速機１０を容易に設置することができる。 In such an elevator apparatus, the pull-up lever shaft 9 and the governor rope 12 are connected using the additional connecting device 14 having the additional extension shaft 16 and the additional lever 18. The speed governor 10 can be installed at a position away from the emergency stop device 7 in the axial direction of the lifting lever shaft 9. That is, even when the speed governor 10 cannot be installed directly above the existing lifting lever 8a, the new speed governor 10 can be easily installed while diverting the existing emergency stop device 7.
　また、引上レバー連結具２２によりブラケット部１７ａを引上レバー８ａに固定したので、追加連結装置１４を据え付ける際、現地での溶接等の加工の手間を軽減することができる。 Moreover, since the bracket portion 17a is fixed to the pull-up lever 8a by the pull-up lever connector 22, it is possible to reduce the labor of processing such as on-site welding when the additional connecting device 14 is installed.
　さらに、引上レバー軸９の内側又は外側に追加延長軸１６の第１の端部１６ａを差し込むので、既設の引上レバー軸９と新設の追加延長軸１６との芯出しを容易に行うことができる。 Furthermore, since the first end portion 16a of the additional extension shaft 16 is inserted inside or outside the pull-up lever shaft 9, the existing pull-up lever shaft 9 and the new additional extension shaft 16 can be easily centered. Can do.
　次に、エレベータ装置の改修方法について説明する。例えば、調速機を持たない油圧エレベータを実施の形態１のエレベータ装置に改修する場合、既設のかご１の下部に追加連結装置フレーム１５を固定する。次に、追加連結装置フレーム１５に回転自在に保持されている追加延長軸１６の第１の端部１６ａを、引上レバー連結具１７を用いて既設の非常止め装置７の引上レバー軸９に連結する。 Next, a method for repairing the elevator apparatus will be described. For example, when a hydraulic elevator that does not have a governor is modified to the elevator apparatus of the first embodiment, the additional connecting device frame 15 is fixed to the lower portion of the existing car 1. Next, the first end 16 a of the additional extension shaft 16 that is rotatably held by the additional connecting device frame 15 is attached to the lifting lever shaft 9 of the existing emergency stop device 7 by using the lifting lever connector 17. Connect to
　この後、追加延長軸１６の第２の端部１６ｂに追加レバー１８を連結する。一方、昇降路２内に調速機１０及び張り車１３を設置するとともに、調速機シーブ１１及び張り車１３に調速機ロープ１２を巻き掛ける。そして、追加レバー１８を、引上棒１９を用いて調速機ロープ１２に連結する。 Thereafter, the additional lever 18 is connected to the second end portion 16b of the additional extension shaft 16. On the other hand, the speed governor 10 and the tension wheel 13 are installed in the hoistway 2, and the speed governor rope 12 is wound around the speed governor sheave 11 and the tension wheel 13. Then, the additional lever 18 is connected to the governor rope 12 using the pulling bar 19.
　このような改修方法によれば、既設の引上レバー８ａの真上に調速機１０を設置できない場合でも、既設の非常止め装置７を流用しつつ新たな調速機１０を容易に設置することができる。 According to such a repair method, even when the speed governor 10 cannot be installed directly above the existing pull-up lever 8a, the new speed governor 10 can be easily installed while diverting the existing emergency stop device 7. be able to.
　なお、上記の改修方法において、各工程の順番を適宜入れ替えることもできる。例えば、最初に調速機１０を設置したり、工場で組み立てた状態の追加連結装置１４を現地へ据え付けたりしてもよい。
　また、上記の例では、調速機１０を持たない油圧エレベータを実施の形態１のエレベータ装置に改修したが、既設のエレベータ装置のタイプはこれに限定されるものではない。例えば、図１とは異なる位置に調速機が設置されているエレベータ装置を実施の形態１のエレベータ装置に改修する場合にも、この発明は適用できる。
　さらに、上記の例では、サイドフォーク式のエレベータ装置を示したが、かごガイドレールがかごの幅方向の両側に配置されている通常のタイプのエレベータ装置にもこの発明は適用できる。
　さらにまた、上記の例では、追加延長軸１６を引上レバー軸９に直接嵌め合わせたが、必ずしも直接連結しなくてもよい。 In the above repair method, the order of the steps can be changed as appropriate. For example, the speed governor 10 may be installed first, or the additional connecting device 14 assembled in a factory may be installed on site.
In the above example, the hydraulic elevator without the governor 10 is modified to the elevator apparatus of the first embodiment, but the type of the existing elevator apparatus is not limited to this. For example, the present invention can also be applied to a case where an elevator apparatus in which a speed governor is installed at a position different from that in FIG. 1 is modified to the elevator apparatus according to the first embodiment.
Further, in the above example, the side fork type elevator apparatus is shown, but the present invention can also be applied to a normal type elevator apparatus in which the car guide rails are arranged on both sides in the width direction of the car.
Furthermore, in the above example, the additional extension shaft 16 is directly fitted to the pull-up lever shaft 9, but it is not always necessary to directly connect it.
