The invention relates to an elevator structure without a car frame stand column, and belongs to the technical field of elevators, the elevator structure comprises bulges arranged on the outer walls of three side plates and an anti-falling mechanism, the anti-falling mechanism comprises a plurality of plane trident parts, the plurality of plane trident parts are divided into three groups, and the three groups of plane trident parts are vertically arranged on the side walls of an elevator shaft corresponding to the three side plates respectively; a limiting part is arranged on the side wall of the elevator shaft above each plane three-fork part, and when an elevator traction system goes wrong or an elevator car falls due to other reasons, the elevator car can fall at the speed higher than the normal falling speed under the gravity action of the car, so that the elevator car is prevented from falling. At the moment, due to the fact that a certain time difference is needed for intermittent back-and-forth rotation of the two sides of the plane trident part to reset, the elevator car cannot fall, the structure is sensitive, misoperation does not exist, complex cooperation of safety tongs and a speed reducer is not needed, the structure is simple, and the problem that no car frame exists is solved. And the falling risk of the elevator is increased.

    本发明涉及一种无轿架立柱电梯结构,属于电梯技术领域,包括设置三个侧板外壁的凸起和防坠机构,防坠机构包括若干平面三叉部,若干平面三叉部分为三组且三组平面三叉部分别竖直地设置在和三个侧板对应的电梯井侧壁上,每一个平面三叉部上方的电梯井的侧壁均设置有一个限位部,当电梯曳引系统出现问题,或其他原因导致电梯轿厢下坠时,此时在轿厢的重力作用下,会以比正常下降速度更快的速度下坠,此时由于平面三叉部的其中两边间歇往返转动到复位需要一定时间差,此时电梯轿厢就无法下坠,并且此处的结构灵敏,不会存在误动作,不仅不需要安全钳和减速器复杂的配合,且结构简单,解决了没有轿架的存在,增加电梯下坠的风险的问题。
