The invention discloses a safety protection device for a foundation-pit-free added elevator, and belongs to the technical field of added elevators, the safety protection device comprises a main body module, the main body module comprises a mounting frame, the interior of the mounting frame is movably connected with an elevator car, and lifting equipment is arranged between the top of the elevator car and the top of the inner wall of the mounting frame; mounting plates are fixedly connected to the two sides of the inner wall of the mounting frame correspondingly, double-face toothed plates are fixedly connected to the adjacent faces of the two mounting plates correspondingly, through arrangement of a connecting gear, a centrifugal assembly, a linkage assembly and a limiting rail, when an elevator falls, braking can be conducted through centrifugal force, and the safety of the elevator is improved. Compared with existing safety tongs, centrifugal force braking can sense the speed change in the first time, response is almost instant, delay is avoided, the elevator is stopped faster, the accident risk is reduced, the structure is simple, maintenance is convenient, and therefore the maintenance cost is reduced.
本发明公开了一种无基坑加装电梯安全防护装置,属于加装电梯技术领域,包括主体模块,所述主体模块包括安装框架,所述安装框架的内部活动连接有电梯厢,所述电梯厢的顶部与安装框架内壁的顶部之间设置有升降设备,所述安装框架内壁的两侧均固定连接有安装板,两个所述安装板相邻的一面均固定连接有双面齿板,通过衔接齿轮、离心组件、联动组件和限位轨的设置,使得在电梯坠落时,可以通过离心力进行制动,使得电梯只能向上牵引进行救援无法坠落,离心力制动对比现有安全钳能第一时间感应速度变化,几乎瞬间响应,避免延迟,更快制停电梯,降低事故风险,并且结构简单,方便维护,从而降低维护成本。
