The invention discloses an anti-falling device for elevator car maintenance, and relates to the technical field of elevator maintenance instruments, and the anti-falling device is characterized by comprising a main frame plate, a winding wheel is rotatably arranged on the main frame plate, a safety rope wound at the upper end of the winding wheel is fixed on the winding wheel, and a safety belt is arranged at one end, far away from the winding wheel, of the safety rope; supporting arms are further hinged to the two sides of the main frame plate, and support feet used for abutting against the inner wall of an elevator shaft are hinged to the ends, away from the main frame plate, of the supporting arms. The device is in the shape of an arch bridge placed in the forward direction in the state of being installed in an elevator shaft. According to the device, adaptive design is conducted according to the structure of an elevator shaft, the whole structure is supported on the side wall of the shaft in an arch shape when the device is used, and therefore when an elevator car falls, the device can be fixed by abutting against the side wall of the shaft, and the friction force between the device and the shaft is further increased under the gravity effect of personnel; and therefore, the worker can be stably hung and cannot fall off, and potential safety hazards of overhauling work are eliminated.

    本发明公开了一种电梯轿厢检修防坠装置,涉及电梯检修器械技术领域,其技术方案要点是包括主架板,主架板上转动设置有收卷轮,收卷轮上固定有绕卷在其上端的安全绳,安全绳远离收卷轮的一端设置有安全带;主架板的两侧还铰接有支撑臂,支撑臂远离主架板的一端铰接有用于与电梯井道内壁抵合的支座脚;装置在安装于电梯井内的状态下呈正向放置的拱桥形状。本装置针对电梯井道的结构进行适配设计,使其使用时整体结构呈拱形支撑在井道侧壁上,从而当电梯轿厢坠落时,装置整体会通过与井道侧壁抵撑形成固定,且在人员重力作用下使得装置与井道之间的摩擦力进一步增大,进而能够稳定对工作人员进行悬挂,使其不会发生坠落,消除了检修工作的安全隐患。
