Description

この発明は、バックプランジャ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 of renewing an indirect hydraulic elevator called a back plunger system as a rope type elevator, and a rope type elevator renewed by the method.

図１はバックプランジャ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はバックプランジャ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に立設されたかご側ガイドレール、３は昇降路１に立設されたジャッキ側ガイドレール、４はかご側ガイドレール２に案内されるエレベータのかご、５は昇降路１のピットに設置されたジャッキ台、６はジャッキ台５の上部に設けられたジャッキ延長具、７はジャッキ延長具６の上端部に連結された油圧ジャッキのシリンダ、８は油圧ジャッキのプランジャ、９は油圧ジャッキのプランジャ８の頂部に設けられた押し上げ車、１０はジャッキ側ガイドレール３に案内されるジャッキガイド、１１はかご４の底部に設けられた綱止め梁で、かご４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。１２は押し上げ車９に巻き掛けられた主索で、一端はかご４の底部の綱止め梁１１に固定され、他端はジャッキ台５に固定されている。１３は昇降路１のピットに設置されたかご側緩衝器、１４は乗場出入口である。
バックプランジャ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８の頂部に固定された押し上げ車９に巻き掛けた主索１２の一端に人が乗るかご４を締結し、主索１２の他端を油圧ジャッキ下部のジャッキ台５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４を昇降させる方式である。かご４の移動量は、油圧ジャッキのプランジャ８の移動量の２倍となり、油圧ジャッキのプランジャ８を全圧縮したときの長さは、昇降行程の約半分程度である。この方式では、かご４の反乗場側の床部を吊持しているため、かご側ガイドレール２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った。また、ジャッキ側ガイドレール３は油圧ジャッキのプランジャ８を案内するだけの役割であるため、かご側ガイドレール２に比較して細く、少なくともプランジャ８の移動範囲に設けられている。
このように構成された間接式油圧エレベータは、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必要となった。 FIG. 1 is a longitudinal sectional view of a hoistway showing an example of an indirect hydraulic elevator called a back plunger system, and FIG. 2 is a transverse sectional view of a hoistway showing an example of an indirect hydraulic elevator called a back plunger system. In the figure, 1 is a hoistway, 2 is a car side guide rail standing on the hoistway 1, 3 is a jack side guide rail standing on the hoistway 1, and 4 is an elevator guided by the car side guide rail 2. The cage 5 is a jack stand installed in the pit of the hoistway 1, 6 is a jack extension provided at the top of the jack stand 5, and 7 is a hydraulic jack cylinder connected to the upper end of the jack extension 6, 8 is a plunger of a hydraulic jack, 9 is a push-up wheel provided at the top of the plunger 8 of the hydraulic jack, 10 is a jack guide guided by the jack-side guide rail 3, and 11 is a bracing beam provided at the bottom of the car 4. In order to suspend the floor portion on the side opposite to the landing side of the car 4, it protrudes on the hydraulic jack side. Reference numeral 12 denotes a main rope wound around the push-up wheel 9, one end being fixed to the rope clamp 11 at the bottom of the car 4 and the other end being fixed to the jack stand 5. 13 is a car side shock absorber installed in the pit of the hoistway 1, and 14 is a landing entrance.
An indirect hydraulic elevator called a back plunger system is configured such that a car 4 is placed on one end of a main rope 12 wound around a push-up wheel 9 fixed to the top of a plunger 8 of a hydraulic jack standing in a hoistway 1. The other end of the main rope 12 is fastened to the jack base 5 below the hydraulic jack, and the car 4 is lifted and lowered by the hydraulic pressure of the 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 4 is twice the moving amount of the plunger 8 of the hydraulic jack, and the length when the plunger 8 of the hydraulic jack is fully compressed is about half of the lifting / lowering stroke. In this method, since the floor portion of the car 4 on the side opposite to the landing is suspended, a reaction force that bends the car-side guide rail 2 acts, so that it is necessary to use a large-sized guide rail. Further, since the jack side guide rail 3 only serves to guide the plunger 8 of the hydraulic jack, the jack side guide rail 3 is thinner than the car side guide rail 2 and is provided at least in the movement range of the plunger 8.
The indirect hydraulic elevator configured as described above is widely used in low-rise buildings because of its simple structure and the ability to install a machine room at an arbitrary position away from the hoistway.
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 was necessary to renew the traction-type rope elevator with a car and a counterweight suspended at both ends of a main rope wound around a sheave fastened to a hoist installed in a hoistway.

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).

3 to 5, the same reference numerals as those in FIGS. 1 to 2 denote the same or corresponding parts. 15 is a rope-type counterweight-side guide rail that is newly installed outside the position where the jack-side guiderail 3 is erected, and 16 is installed horizontally across the upper end of the counterweight-side guide rail 15. The hoisting machine base 17 is hoisted and installed on the hoisting machine base 16, 18 is a driving sheave of the hoisting machine 17, 19 is a brake device of the hoisting machine 17, and 20 is Tightening plates provided on the hoisting machine base 16, 21 a counterweight frame guided by the counterweight side guide rail 15, and 22 an existing hydraulic jack provided vertically at the center of the counterweight frame 21. The shortest length (full compression state) in which the plunger 8 is accommodated in the cylinder 7 is used. Reference numeral 23 denotes an additional weight provided on both the left and right sides of the hydraulic jack 22 at the center of the counterweight frame 21, reference numeral 24 denotes a counterweight upper suspension car provided at the upper center of the counterweight frame 21, and reference numeral 25 denotes a hoist. A rope-type elevator main rope wound around a driving sheave 18 of the machine 17, one end of which is fastened to a rope holding beam 11 provided at the bottom of the car 4, and the other end is a counterweight. It is returned upward through the upper suspension wheel 24 and is fastened to a rope holding plate 20 provided on the hoisting machine base 16 to suspend a counterweight.

このようにロープ式エレベータにリニューアルされたエレベータにおいても、かご４の移動量は、既設の油圧ジャッキ２２と一体で構成されたつり合いおもりの移動量の２倍となる。また、つり合いおもりは、既設の油圧ジャッキのシリンダ７内にプランジャ８を収納した最短長さ（全圧縮状態）として、追加おもり２３と一体で構成されている。また、この方式では、かご側とつり合いおもり側のレールの吊り荷重による垂直方向の荷重が作用するようになるが、かご側のレールは元々大きなかごの反力に耐えるよう大きなサイズのレールを用いているため、交換する必要が無いものの、つり合いおもり側のレールは長さ、サイズともに流用できないため、新規に設置しなければならない。 In the elevator renewed to the rope type elevator as described above, the moving amount of the car 4 is twice the moving amount of the counterweight constructed integrally with the existing hydraulic jack 22. The counterweight is integrally formed with the additional weight 23 as the shortest length (full compression state) in which the plunger 8 is accommodated in the cylinder 7 of the existing hydraulic jack. Also, with this method, the vertical load is applied by the suspension load of the weight side rails against the car side, but the rails on the car side originally use large size rails to withstand the reaction force of the large car. Therefore, although there is no need to replace it, the rail on the counterweight side cannot be diverted in both length and size, so it must be newly installed.

通常、油圧ジャッキは昇降行程の約半分の長さで設置されるため、昇降行程が長いと、ジャッキ本体が長くなり、必要なつり合いおもり重量から決まるつり合いおもり枠の高さ以内に収まらないことがある。そこで、つり合いおもりの下部に吊り車２９を設けるとともに、つり合いおもり枠２１の下面を基準に油圧ジャッキ２２を組み込むようにしたので、つり合いおもり枠２１の上部枠から上部方向に油圧ジャッキ２２が突出する構成となる。よって、ジャッキ支持具３０で油圧ジャッキ２２の突出部分を支持している。これにより、かご４が最上階に位置するときにつり合いおもりが最下階付近に位置するように設置することができる。このように構成されたつり合いおもりは、かごの昇降行程の半分しか移動しないので、昇降路の下面や天井と適正な隙間をもって昇降できるようになる。 In the first embodiment, the counterweight upper suspension car 24 is installed in the upper center portion of the counterweight frame 21, but in this embodiment 2, the counterweight lower suspension car 29 is installed in the lower center portion of the counterweight frame 21. It is a thing. Reference numeral 30 denotes a jack support provided on the upper frame of the counterweight frame 21.
Normally, hydraulic jacks are installed at approximately half the length of the lifting stroke, so if the lifting stroke is long, the jack body will be long and may not fit within the height of the counterweight frame determined by the required weight of the counterweight. is there. Therefore, since the suspension wheel 29 is provided at the lower part of the counterweight and the hydraulic jack 22 is incorporated with the lower surface of the counterweight frame 21 as a reference, the hydraulic jack 22 protrudes upward from the upper frame of the counterweight frame 21. It becomes composition. Therefore, the jack support 30 supports the protruding portion of the hydraulic jack 22. Thereby, when the car 4 is located on the uppermost floor, the counterweight can be installed so as to be located near the lowermost floor. Since the counterweight constructed in this way moves only half of the car's lifting process, it can move up and down with an appropriate gap from the lower surface and ceiling of the hoistway.
