Abstract

This car-suspending wheel assembly comprises lateral beams attached to an elevator car, car-suspending wheels rotatably supported by the lateral beams, and vertical reinforcers that are attached to and reinforce the lateral beams. The vertical reinforcers project further away from the elevator car than the car-suspending wheels in the up-down direction. Therefore, when the car-suspending wheels have been detached from the elevator car in each car-suspending wheel assembly, it is possible to mount the car-suspending wheel assembly by earthing the vertical reinforcing material but not earthing the car-suspending wheels. It is therefore possible to prevent the car-suspending wheels from being damaged.

Description

かご吊り車組立体Car suspension car assembly

　この発明は、例えば、エレベータの乗りかごを吊るためのかご吊り車を備えるかご吊り車組立体に関する。 The present invention relates to, for example, a car suspension car assembly including a car suspension car for suspending an elevator car.

　エレベータの乗りかごの下側には、かご吊り車が設けられている。吊り車梁の両端には、綱車が取り付けられている。吊り車梁には、左右の綱車間に架け渡されたロープ張力により圧縮荷重が作用すると共に、両端の綱車の、かごを吊るロープ張力により、過大なモーメント荷重が作用する。 か A car suspension car is provided below the elevator car. The sheaves are attached to both ends of the suspension sheave beam. A compressive load acts on the suspended sheave beam due to the rope tension bridged between the left and right sheaves, and an excessive moment load acts on the suspended sheave beams due to the rope tensions of the sheaves at both ends for hanging the car.

　そのため、吊り車梁には、過大な断面性能が要求されるため、吊り車梁の断面高さは、綱車直径よりも僅かに小さい位であった。そのため、綱車の下方のロープ外れ止めは、吊り車梁に小さな金具で直接取り付けられていた（例えば、特許文献１参照）。 Therefore, the excessive cross-sectional performance is required for the suspended sheave beam, and the sectional height of the suspended sheave beam was slightly smaller than the sheave diameter. Therefore, the rope stopper below the sheave was directly attached to the suspension sheave beam with a small metal fitting (for example, see Patent Document 1).

国際公開第２００７／０９４３６７号International Publication No. 2007/0994367

　しかしながら、かご吊り車の組立て作業または運搬を行う時には、ロープ外れ止めが壊れないように、かご吊り車からロープ外れ止めを外しておいて、綱車を直接接地させていた。そのため、綱車の一部に傷がつく可能性があった。 However, when assembling or transporting the car hanging car, the rope shed was removed from the car hanging car and the sheave was directly grounded so that the rope shed was not broken. Therefore, there was a possibility that a part of the sheave was damaged.

　この発明は、このような問題を解決するためになされたものであり、綱車に傷がつくことを防止することができる、かご吊り車組立体を提供することを目的とする。 The present invention has been made to solve such a problem, and an object of the present invention is to provide a car hanging wheel assembly capable of preventing a sheave from being damaged.

　上記の課題を解決するために、この発明に係るかご吊り車組立体は、乗りかごに取り付けられる横梁と、横梁に回転可能に支持されるかご吊り車と、横梁に取り付けられ、横梁を補強する縦補強材とを備え、縦補強材は、上下方向について、かご吊り車よりも乗りかごから離れる方向に突出する。 In order to solve the above problems, a car suspension car assembly according to the present invention includes a cross beam attached to a car, a car suspension car rotatably supported by the cross beam, and a car beam mounted on the cross beam to reinforce the cross beam. A vertical reinforcing member, and the vertical reinforcing member protrudes in the vertical direction in a direction away from the car than the car suspension vehicle.

　この発明に係るかご吊り車組立体によれば、かご吊り車に傷がつくことを防止することができる。 According to the car suspension car assembly according to the present invention, it is possible to prevent the car suspension car from being damaged.
