Abstract

L'invention concerne un châssis de cabine pour un ascenseur utilisant une courroie en acier. Le châssis de cabine comprend deux poutres longitudinales (1) agencées en parallèle, un ensemble poutres supérieures (2) et un ensemble poutres inférieures (3), l'ensemble poutres supérieures (2) et l'ensemble poutres inférieures (3) étant reliés entre les deux poutres longitudinales (1). Chaque poutre longitudinale (1) comprend une plaque latérale principale (11) et des plaques latérales auxiliaires (12), agencées de part et d'autre de la plaque latérale principale (11), les plaques latérales principales des deux poutres longitudinales (1) étant agencées face à face. L'ensemble poutres supérieures (2) comprend des poutres supérieures (21) et une plaque de liaison supérieure (22). L'ensemble poutres inférieures (3) comprend des poutres inférieures (31) et des plaques de liaison inférieures (32), les poutres inférieures (31) étant agencées parallèlement aux poutres supérieures (21), les plaques de liaison inférieures (32) étant agencées perpendiculairement aux poutres longitudinales (1) et aux poutres inférieures (31) ; des trous de montage traversants sont formés dans les deux plaques de liaison inférieures (32), et les deux extrémités de chaque poutre inférieure (31) passent à travers les trous de montage opposés (33) des deux plaques de liaison inférieures (32) de manière solidarisée. Selon le châssis de cabine pour ascenseur utilisant une courroie en acier, les plaques latérales auxiliaires des poutres supérieures et les poutres longitudinales sont fixées par des ensembles boulons ou par soudage, ce qui réduit la hauteur globale du châssis de cabine. Les plaques de liaison inférieures et les poutres inférieures de l'ensemble poutres inférieures sont fixées d'une manière interpénétrante, et un ensemble poulie de déviation est agencé entre deux plaques d'aile de façon à être relié en rotation aux poutres inférieures, ce qui permet de réduire la profondeur requise de la gaine d'ascenseur et de réduire davantage la hauteur globale du châssis de cabine.
