The invention discloses an elevator car frame structure which comprises an elevator car, a car roof, an upper beam assembly located above the car roof, a car bottom assembly installed at the bottom of the elevator car, a lower beam assembly installed at the bottom of the car bottom assembly and vertical beams installed on the two sides of the elevator car, and the lower ends of the vertical beams are installed on the two sides of the car bottom assembly and the two sides of the lower beam assembly. The upper beam assembly is mounted at the upper end of the vertical beam; two diversion sheave structures are mounted on the upper beam assembly; safety tongs are embedded in the two ends of the lower beam assembly, safety lifting devices connected with the safety tongs are arranged on the two sides of the lower beam assembly, and the safety lifting devices are in transmission connection with a speed limiter steel wire rope. The double-diversion-sheave elevator has the advantages that due to the double-diversion-sheave structure locally hidden in the upper beam assembly, steel wire rope wrap angle hanging is increased, a machine room diversion sheave elevator structure is reduced, and the height of a car frame is effectively reduced; the car bottom assembly is simple in structure, the car bottom rigidity is improved, and the safety tongs, the safety lifting device and the lower beam assembly are of an integrated structure, so that the lifting synchronism of the safety tongs is good; the vertical beam and car space problem is solved, the car frame width size is effectively reduced, and the hoistway size is reduced.

    本发明公开了一种电梯轿架结构,包括轿厢、轿顶、位于轿顶上方的上梁组件、安装在轿厢底部的轿底组件、安装在轿底组件底部的下梁组件、安装在轿厢两侧的立梁,立梁的下端安装在轿底组件和下梁组件的两侧上,上梁组件安装在立梁的上端上;上梁组件上安装有2个反绳轮结构;下梁组件两端内嵌装有安全钳,下梁组件两侧设有与安全钳连接的安全提拉装置,安全提拉装置与限速器钢丝绳传动连接。本发明优点包括:局部藏在上梁组件内的双反绳轮结构,增大钢丝绳包角吊挂,减少机房反绳轮电梯结构,有效降低轿架高度;轿底组件结构简单,提高轿底刚度,安全钳、安全提拉装置、下梁组件一体式结构使安全钳提拉同步性好;解决立梁和轿厢空间问题,有效减少轿架宽度尺寸,减少井道尺寸。
