Description
本発明は、エレベータ装置に係り、特に、昇降路内のスペースを利用して巻上機を設置した機械室レスのエレベータの巻上機支持構造に関する。 The present invention relates to an elevator apparatus, and more particularly to a machine room-less elevator hoisting machine support structure in which a hoisting machine is installed using a space in a hoistway.
近年、建物の利用効率を高めるため、昇降路内のスペースを利用して巻上機や制御盤などを設置するエレベータ、いわゆる機械室レスエレベータとして、昇降路内を昇降するかごと、このかごと対向方向に移動するカウンターウェイトと、かごおよびカウンターウェイトの昇降を案内するガイドレールと、かごおよびカウンターウェイトを懸架するロープと、昇降路内にあって昇降路最下階フロアレベル付近にあり、かつ、昇降路の平断面内の１つの壁面に平行に配置された薄形の巻上機とから構成したものが提案され一部実用化されている。そして、前述した巻上機の支持として、機械台により防振ゴムを介して巻上機台を吊り下げ、巻上機台に巻上機を固定するもの（例えば、特許文献１参照）、或いは、巻上機を固定する固定台をロ字状に組み立てガイドレールに移動可能に固定したものがある（例えば、特許文献２参照）。 In recent years, in order to increase the efficiency of use of buildings, elevators that install hoisting machines and control panels using the space in the hoistway, so-called machine room-less elevators, are used to raise and lower the hoistway. A counterweight that moves in the opposite direction, a guide rail that guides the raising and lowering of the car and the counterweight, a rope that suspends the car and the counterweight, and is located near the floor level at the lowest floor of the hoistway in the hoistway, and A structure composed of a thin hoisting machine arranged in parallel with one wall surface in the plane cross section of the hoistway has been proposed and partially put into practical use. And as a support of the hoisting machine described above, the hoisting machine base is suspended by a mechanical base via a rubber vibration isolator and the hoisting machine is fixed to the hoisting machine base (for example, see Patent Document 1), or There is one in which a fixing base for fixing the hoisting machine is fixed to an assembly guide rail so as to be movable in a square shape (for example, see Patent Document 2).
しかしながら、引用文献１に記載のものでは、吊り下げた固定台の上に巻上機を載せた後、巻上機を固定する構造としているため、巻上機の外側に吊り下げ部材を通さなければならず、巻上機幅に加え、吊り下げ部材の幅寸法が必要となり、昇降路寸法が拡大するという問題があった。 However, in the thing of the cited reference 1, since it has the structure which fixes a hoisting machine after mounting a hoisting machine on the suspended fixing stand, you must pass a suspension member on the outer side of a hoisting machine. In addition to the hoisting machine width, the width of the suspension member is required, and the hoistway dimension is increased.
一方、引用文献２に記載のものでは、固定台を、上枠、下枠および側枠でロ字状に組み立てるとともに、上枠と下枠のそれぞれの一端をガイドレールに移動可能に固定し、かつ、下枠をテンションロッドによってピットベースに固定した構成であるが、巻上機に対する側枠の配置は特に限定されておらず、側枠が巻上機の外側に配置された場合、特許文献１と同様に巻上機幅に加え、側枠の幅寸法が必要となる。また、固定台の厚さ寸法を低減するための特別な配慮はなされておらず、したがって、昇降路寸法が拡大するという問題があった。 On the other hand, in the one described in the cited document 2, the fixing base is assembled in a square shape with the upper frame, the lower frame and the side frame, and one end of each of the upper frame and the lower frame is movably fixed to the guide rail, And although it is the structure which fixed the lower frame to the pit base with the tension rod, arrangement of the side frame with respect to the hoisting machine is not particularly limited, and when the side frame is arranged outside the hoisting machine, the patent document As with 1, the width of the side frame is required in addition to the hoisting machine width. Further, no special consideration has been given to reduce the thickness dimension of the fixed base, and therefore there has been a problem that the hoistway dimension is enlarged.
本発明は、上述した従来技術における実状からなされたもので、その目的は、構成部品を大幅に変更することなく、昇降路寸法の拡大防止を図ることのできるエレベータ装置を提供することにある。 The present invention has been made from the above-described prior art, and an object of the present invention is to provide an elevator apparatus capable of preventing the hoistway dimensions from being enlarged without significantly changing the components.
