Description

この発明は、サイドフォーク方式と呼ばれる間接式油圧エレベータをロープ式エレベータとしてリニューアルする方法及びその方法によりリニューアルされたロープ式エレベータに関するものである。 The present invention relates to a method for renewing an indirect hydraulic elevator called a side fork type as a rope type elevator, and a rope type elevator renewed by the method.

図１はサイドフォーク方式と呼ばれる間接式油圧エレベータの一例を示す昇降路の縦断面図、図２はサイドフォーク方式と呼ばれる間接式油圧エレベータの一例を示す昇降路の横断面図である。図中、１は昇降路、２は昇降路１に立設されたジャッキ側ガイドレール、３はエレベータのかご、４はかご３の反乗場側の両側部に設けられた立柱、５はかご３の底部の反乗場側の両側部に設けられたかご支持梁で、立柱４とともにリックサックのようにかご３を片持ち支持している。６は昇降路１のピットに設置されたジャッキ台、７はジャッキ台６の上部に設けられたジャッキ延長具、８はジャッキ延長具７の上端部に連結された油圧ジャッキのシリンダ、９は油圧ジャッキのプランジャ、１０は油圧ジャッキのプランジャ９の頂部に設けられた押し上げ車、１１はジャッキ側ガイドレール２に案内されるジャッキガイド、１２はかご３の底部に設けられた綱止め梁で、かご３の反乗場側である床部を吊持するために油圧ジャッキ側に突設されている。１３は押し上げ車１０に巻き掛けられた主索で、一端はかご３の底部の綱止め梁１２に固定され、他端はジャッキ台６に固定されている。１４は左右両側の立柱４の上下端部にそれぞれ設けられた大型・大径の樹脂製ガイドローラで、ジャッキ側ガイドレール２の頂部と左右両側面の３個所を支持しながら転動し、かご３を昇降する。１５は昇降路１のピットに設置されたレール台、１６はレールブラケット、１７は乗場出入口である。
サイドフォーク方式と呼ばれる間接式油圧エレベータは、昇降路１内に立設された油圧ジャッキのプランジャ９の頂部に固定された押し上げ車１０に巻き掛けた主索１３の一端に人が乗るかご３を締結し、主索１３の他端を油圧ジャッキ下部のジャッキ台６に締結し、昇降路１に隣接した機械室に設置されたパワーユニット（図示せず）の油圧力により油圧ジャッキの昇降とともにかご３を昇降させる方式である。かご３の移動量は、油圧ジャッキのプランジャ９の移動量の２倍となる。この方式では、かご３の反乗場側に設けた立柱４とかご支持梁５とがリックサックのようにかご３を片持ち支持しており、主索１３が、かご３の床部の綱止め梁１２を吊持しているため、かご３側のレールを曲げる反力が作用するので、大きなサイズのガイドレールを用いる必要がある。また、このかご３の反力が極めて大きく、樹脂製ガイドローラ１４が変形して昇降に伴う振動を発生し、乗り心地を損なう問題があるため、大型・大径の樹脂製ガイドローラを用いる必要があった。そして、大型・大径の樹脂製ガイドローラを用いると、かごの高さ方向寸法が大きくなるため、かごが最上階に停止したときの昇降路天井までの隙間が小さくなり過ぎ、かごの高さを制限しなければならないという問題があった。
このように構成された間接式油圧エレベータは、乗り心地が劣るものの、構造が簡単で昇降路から離れた任意の位置に機械室を設置できるなどの特長があることから、低層の建物に普及している。
しかし、近年の社会環境は、省エネやクリーンな環境に対する要求が高く、エネルギ効率が高く、しかも容易に輸送効率を向上できるロープ式エレベータへのリニューアル化が望まれるようになってきた。そこで、昇降路内に設置した巻上機に締結された綱車に巻き掛けた主索の両端にかご及びつり合いおもりを吊持したトラクションタイプのロープ式エレベータへのリニューアル化が考えられるが、長期間にわたってエレベータを停止することは、利用者の利便性を損なうことから短期間でリニューアルできるエレベータシステムが望まれる。 FIG. 1 is a longitudinal sectional view of a hoistway showing an example of an indirect hydraulic elevator called a side fork system, and FIG. 2 is a transverse sectional view of a hoistway showing an example of an indirect hydraulic elevator called a side fork system. In the figure, 1 is a hoistway, 2 is a jack side guide rail standing on the hoistway 1, 3 is an elevator car, 4 is an upright column provided on both sides of the car 3 on the opposite side of the landing, and 5 is a car 3. The car 3 is cantilevered like a ricksack together with the uprights 4 with car support beams provided on both sides of the bottom of the car. 6 is a jack base installed in the pit of the hoistway 1, 7 is a jack extension provided at the upper part of the jack base 6, 8 is a hydraulic jack cylinder connected to the upper end of the jack extension 7, and 9 is a hydraulic pressure. A jack plunger, 10 is a push-up wheel provided at the top of a hydraulic jack plunger 9, 11 is a jack guide guided by the jack side guide rail 2, and 12 is a rope anchoring beam provided at the bottom of the car 3. No. 3 is provided on the side of the hydraulic jack so as to suspend the floor on the side opposite to the landing. Reference numeral 13 denotes a main rope wound around the push-up wheel 10, one end of which is fixed to the rope clamp 12 at the bottom of the car 3 and the other end is fixed to the jack stand 6. 14 is a large and large-sized resin guide roller provided at the upper and lower ends of the vertical pillars 4 on both the left and right sides, and rolls while supporting the top part of the jack side guide rail 2 and the left and right side surfaces. Move 3 up and down. 15 is a rail base installed in the pit of the hoistway 1, 16 is a rail bracket, and 17 is a landing entrance.
An indirect hydraulic elevator called a side fork system has a car 3 placed on one end of a main rope 13 wound around a push-up wheel 10 fixed to the top of a plunger 9 of a hydraulic jack standing in a hoistway 1. The other end of the main rope 13 is fastened to the jack base 6 below the hydraulic jack, and the car 3 is lifted and lowered by the hydraulic pressure of a power unit (not shown) installed in the machine room adjacent to the hoistway 1. Is a method of moving up and down. The moving amount of the car 3 is twice the moving amount of the plunger 9 of the hydraulic jack. In this system, the upright column 4 and the car support beam 5 provided on the opposite side of the car 3 support the car 3 in a cantilever manner like a ricksack, and the main rope 13 holds the rope of the floor of the car 3. Since the beam 12 is suspended, a reaction force that bends the rail on the car 3 side acts, so that it is necessary to use a large-sized guide rail. Further, since the reaction force of the car 3 is extremely large and the resin guide roller 14 is deformed to generate vibrations caused by raising and lowering, and the ride comfort is impaired, it is necessary to use a large and large diameter resin guide roller. was there. And if you use a large and large diameter resin guide roller, the height dimension of the car will increase, so when the car stops on the top floor, the gap to the hoistway ceiling becomes too small, and the height of the car There was a problem that had to be restricted.
Although the indirect hydraulic elevator constructed in this way is inferior in riding comfort, it has the features that the machine room can be installed at an arbitrary position away from the hoistway because of its simple structure and is popular in low-rise buildings. ing.
However, in recent years, there has been a high demand for energy saving and a clean environment, and there has been a demand for a renewal to a rope type elevator that has high energy efficiency and can easily improve transportation efficiency. Therefore, it is conceivable to renew the traction type rope-type elevator with a cage and a counterweight suspended at both ends of the main rope wound around the sheave fastened to the hoist installed in the hoistway. Since stopping the elevator over a period of time impairs the convenience of the user, an elevator system that can be renewed in a short period of time is desired.

また、従来技術として、油圧エレベータの構成要素を機械室エレベータの構成要素として流用し、油圧エレベータの搭載構成部品からプランジャレールを撤去するだけで、リニューアルに要するコストを低減する油圧エレベータのリニューアル方法が提案されている（例えば、特許文献１参照）。また、他の従来技術として、既設の油圧シリンダおよびプランジャは撤去せずにそのままブラケットなどにより固定して基台とし、プランジャの頂部の既設の回転シーブを取り外して薄形電動巻上機を新たに設けるとともに、昇降路内に新たに吊り合い重りを設け、薄形電動巻上機の回転シーブを介して主索により乗りかごと吊り合い重りとを連結し、薄形電動巻上機を制御するマイコン制御盤を新たに設けて、ロープ式エレベータとしてリニューアルするエレベータのリニューアル方法が提案されている(例えば、特許文献２参照)。 Also, as a conventional technology, there is a hydraulic elevator renewal method that reduces the cost required for renewal by simply using the components of the hydraulic elevator as components of the machine room elevator and removing the plunger rail from the components mounted on the hydraulic elevator. It has been proposed (see, for example, Patent Document 1). In addition, as another conventional technology, the existing hydraulic cylinder and plunger are not removed and fixed as they are with a bracket or the like as a base, and the existing rotary sheave at the top of the plunger is removed, and a thin electric hoist is newly added. In addition to providing a lifting weight in the hoistway, the main electric rope is connected to the lifting weight by the main rope via the rotating sheave of the thin electric hoist to control the thin electric hoist There has been proposed an elevator renewal method in which a microcomputer control panel is newly provided and renewed as a rope type elevator (for example, see Patent Document 2).
