Description

この発明は、防振装置及び振れ止めを備えるエレベータのかご床装置に関する。   The present invention relates to an elevator car floor device including a vibration isolator and a steady rest.

従来のエレベータのかご床装置においては、乗客が乗降するかご床面を支えるかご床枠と、かごを懸架するかご枠と一体のかご下枠との間に防振装置が設けられ、これによりかご床枠側ではかご下枠側で生じる振動を緩和している。さらに防振装置とは別にかご床枠とかご下枠それぞれに一対の振れ止めが設けられ、これにより横揺れ時、かご床枠とかご下枠とが横方向にずれるのを抑制している。
またエレベータのかご床装置に適用されたものではないが、巻上機の機械台に設けられた防振装置に、振れ止めと防振バネを一体的に備えた防振装置（例えば特許文献１参照）、また振れ止め内部に防振ゴムを備えた防振装置がある（例えば特許文献2参照）。 In a conventional elevator car floor device, a vibration isolator is provided between a car floor frame that supports the car floor on which passengers get on and off, and a car frame that suspends the car and a car lower frame that is integral with the car floor frame. On the floor frame side, vibration generated on the car lower frame side is reduced. In addition to the vibration isolator, a pair of steady rests are provided for each of the car floor frame and the car lower frame, thereby preventing the car floor frame and the car lower frame from shifting laterally when rolling.
Further, although not applied to an elevator car floor device, an anti-vibration device provided with an anti-vibration device and an anti-vibration spring integrally with an anti-vibration device provided on a machine base of a hoisting machine (for example, Patent Document 1). Also, there is a vibration isolator having an anti-vibration rubber inside the steady rest (see, for example, Patent Document 2).

特開2002−362860号公報（第5−6項、第4図）JP 2002-362860 (Section 5-6, Fig. 4) 実開昭57−85566号公報（第4項、第3図）Japanese Utility Model Publication No.57-85566 (Section 4, Figure 3)

従来のエレベータのかご床装置では、防振装置と振れ止めが別体であるため、占有スペースが大きく、また防振装置と振れ止めを取付ける作業時間が長いという問題点があった。
ここで特許文献１記載の防振装置をエレベータのかご床装置に適用した場合、この防振装置は振れ止めと一体化された防振コイルバネで構成され、省スペース化されているが、一般のエレベータのかご床装置では防振ゴム等の防振体はボルトにて固定されている為、既存のエレベータのかご床装置に適用できず汎用性に欠ける、また防振体を交換する際、ボルトからコイルバネを取り外せる高さまで嵩上げして、全て取り外さなければならず時間がかかるという問題がある。また、振れ止めである筒部が金属であれば、かごに乗客が乗降するときやかごが昇降する時など、かごに横揺れが生じた時、金属同士の衝突音があり、乗客に不快感を与える可能性が生じる。
特許文献2記載の防振装置をエレベータのかご床装置に適用した場合、上記の問題に加え、嵌合孔の取り付けの場合、穴及び凸部の寸法精度などによりぐらつきが生じる可能性がある。また防振ゴムと保持具を同時に取り付ける必要があり、取り付け作業時間を要する、という問題点がある。 In the conventional elevator car floor device, the vibration isolator and the steady rest are separate from each other, so that there is a problem that the occupied space is large and the work time for attaching the vibration isolator and the steady rest is long.
Here, when the vibration isolator described in Patent Document 1 is applied to an elevator car floor apparatus, the vibration isolator is constituted by an anti-vibration coil spring integrated with a steady rest and is space-saving. In elevator car floor devices, vibration isolators such as anti-vibration rubber are fixed with bolts, so they cannot be applied to existing elevator car floor devices and lack generality. Therefore, there is a problem that it takes time to raise the coil spring to a height at which the coil spring can be removed and to remove all the coil springs. Also, if the cylindrical part that is the steady rest is metal, when the car rolls, such as when the passenger gets on and off the car or when the car goes up and down, there is a collision sound between the metals, which makes the passenger uncomfortable The possibility of giving.
When the vibration isolator described in Patent Document 2 is applied to an elevator car floor device, in addition to the above-described problem, when fitting holes are attached, wobbling may occur due to the dimensional accuracy of the holes and protrusions. In addition, there is a problem that it is necessary to attach the anti-vibration rubber and the holding tool at the same time, and it takes time for the attachment work.

この発明は、上述のような課題を解決するためになされたもので、エレベータのかご床装置の省スペース化とともに、防振ゴム、振れ止めの交換及び取付作業時間を短縮でき、これらを既存のかご床に適用できるエレベータのかご床装置を得るものである。   The present invention has been made to solve the above-described problems. In addition to saving space in the elevator car floor device, the vibration-proof rubber, the replacement of the steady rest and the mounting work time can be shortened. An elevator car floor apparatus that can be applied to a car floor is obtained.

この発明に係るエレベータのかご床装置においては、かご床枠と、かご床枠の下面と対向し、かご床枠を支持するかご下枠と、かご下枠側もしくはかご床枠側のいずれか一方から立設された筒状部を有する第一振れ止めと、かご下枠側もしくはかご床枠側の第一振れ止めの他方から立設され、外面が第一振れ止めの筒状部の内面と所定の間隔で重合するように対向する筒状部を有する第二振れ止めと、かご床枠側およびかご下枠側にそれぞれ固着された防振体と、を備えたものである。   In the elevator car floor device according to the present invention, the car floor frame, the car lower frame facing the lower surface of the car floor frame and supporting the car floor frame, and either the car lower frame side or the car floor frame side A first steady rest having a cylindrical portion erected from the other side of the first steady rest on the car lower frame side or the car floor frame side, and the outer surface is an inner surface of the cylindrical portion of the first steady rest A second steady rest having cylindrical portions facing each other so as to be superposed at a predetermined interval, and a vibration isolator fixed to the car floor frame side and the car lower frame side, respectively.

この発明は、エレベータかご床装置の省スペース化と、改修時における作業を容易とすることができる。   The present invention can save space in an elevator car floor device and facilitate work at the time of repair.

The buffer material 10 is provided over the entire outer peripheral surface of the cylindrical second steady rest 9. Here, the outer diameter of the cylindrical cylindrical second steady rest 9 is smaller than the inner diameter of the cylindrical first steady rest 8, and the inner peripheral surface of the upper end portion of the cylindrical first steady rest 8 and the cylindrical shape. The outer peripheral surface of the lower end portion of the second steady rest 9 faces the entire circumference with an equal gap interval δ.

次に防振装置3の組立方法を図3を用いて説明する。先ず上面中央部に円筒状の第一振れ止め8が溶接固定された下板6に防振ゴム4を接着等で固定する。この時、防振ゴム4の外周面と円筒状の第一振れ止め8の内周面が全周で等間隔に対向するよう配置する。次に下面中央部に円筒状の第二振れ止め9が溶接固定された上板7を防振ゴム4の上面に接着等で固定する。この時、円筒状の第一振れ止め8の上端部の内周面と円筒状の第二振れ止め9の下端部の外周面が全周で等間隔に対向するよう配置する。次に下板6及び円筒状の第一振れ止め8側を、ボルト取付穴6a及び6bと、ボルト、ナットからなる締結部5c及び5dと係合させることでかご下枠2に固定し、上板7及び円筒状の第二振れ止め9側を、ボルト取付穴7a及び7bと、ボルト、ナットからなる締結部5a及び5bとを係合させることでかご床枠1に固定し、これにより防振装置3をかご床装置に備え付ける。 Next, a method for assembling the vibration isolator 3 will be described with reference to FIG. First, the anti-vibration rubber 4 is fixed to the lower plate 6 to which the cylindrical first steady rest 8 is fixed by welding at the center of the upper surface by adhesion or the like. At this time, the outer peripheral surface of the anti-vibration rubber 4 and the inner peripheral surface of the cylindrical first steady rest 8 are arranged so as to face the entire circumference at equal intervals. Next, the upper plate 7 with the cylindrical second steady rest 9 welded and fixed to the center of the lower surface is fixed to the upper surface of the anti-vibration rubber 4 by bonding or the like. At this time, the inner peripheral surface of the upper end portion of the cylindrical first steady rest 8 and the outer peripheral surface of the lower end portion of the cylindrical second steady rest 9 are arranged so as to face each other at equal intervals. Next, the lower plate 6 and the cylindrical first steady rest 8 side are fixed to the car lower frame 2 by engaging the bolt mounting holes 6a and 6b with the fastening portions 5c and 5d made of bolts and nuts. The plate 7 and the cylindrical second steady rest 9 side are fixed to the car floor frame 1 by engaging the bolt mounting holes 7a and 7b with the fastening portions 5a and 5b made of bolts and nuts, thereby preventing it. A shaking device 3 is installed in the car floor device.

以上のように構成されたエレベータのかご床装置において、地震などの横揺れを受けかご床面1とかご下枠2が互いに横方向にずれるとき、予め防振装置3に取付けられた第一振れ止め8と第二振れ止め9とが接触し、その結果それぞれの隙間間隔δ以上の水平方向に振れを防止する。これによりかご床枠１の脱落、転倒を防止することができる。   In the elevator car floor apparatus configured as described above, when the car floor 1 and the car lower frame 2 are laterally displaced from each other due to a roll such as an earthquake, the first runout attached to the vibration isolator 3 in advance is provided. The stop 8 and the second steady rest 9 come into contact with each other, and as a result, the shake is prevented in the horizontal direction over the gap interval δ. As a result, the car floor frame 1 can be prevented from falling off and falling over.

この時、第二振れ止め9の外周に設けられた緩衝材10により、第一振れ止め8の内周と接触する際の騒音を軽減ないしは防止することができる。   At this time, the shock-absorbing material 10 provided on the outer periphery of the second steady rest 9 can reduce or prevent noise when coming into contact with the inner circumference of the first steady rest 8.

また、従来のように防振装置と振れ止めを別々に取付けていたかご床装置に比べて省スペース化が可能となり、また部品点数削減により作業時間短縮に繋がる。   In addition, space can be saved as compared with a conventional car floor apparatus in which a vibration isolator and a steady rest are separately mounted as in the prior art, and work time can be shortened by reducing the number of parts.

また、一般的に既存のかご床装置には防振装置を固定する為、かご床枠1とかご下枠2はそれぞれ防振装置取付穴1a 及び1bと2a及び2b相当のものを備えており、本実施の形態のボルト取付穴6a及び6bと7a及び7bの位置をそれぞれ前記の防振装置取付穴と一致するように設けることで、既存のエレベータのかご床装置をこの発明のエレベータのかご床装置に交換する改修作業はきわめて容易に実施することができる。   In addition, in order to fix the vibration isolator to the existing car floor apparatus, the car floor frame 1 and the car lower frame 2 are provided with vibration isolator mounting holes 1a and 1b and 2a and 2b, respectively. In this embodiment, the bolt mounting holes 6a and 6b and the positions of 7a and 7b are provided so as to coincide with the vibration isolator mounting holes, so that the existing elevator car floor device can be installed in the elevator car of the present invention. The refurbishment work to replace the floor equipment can be performed very easily.
