The invention discloses a novel elevator fall preventing structure. The novel elevator fall preventing structure comprises a well shaft and a car lifting mechanism, wherein a car is arranged in the well shaft; a supporting part which is positioned at one side of a car moving path and is transversely bugled out of the inner wall of the well shaft is arranged in the well shaft; a fall-preventing frame which can transversely move relative to the car and is supported by the supporting part is arranged on the car; and a transverse moving drive device is connected between the car and the fall-preventing frame. The invention further discloses a fall preventing method of the novel elevator fall preventing structure. While the car moves up and down along the well shaft, the fall-preventing frame transversely moves relative to the car to avoid the supporting part in the well shaft; and while the fall-preventing frame is positioned above the supporting part, the fall-preventing frame transverselymoves so as to be positioned at the same side with the supporting part. According to the novel elevator fall preventing structure and the preventing method thereof provided by the invention, a well shaft foundation pit does not need to form, so that applicability is wide; and moreover, the novel elevator fall preventing structure can prevent the car from great-height falling, is high in safety, is good in stability, and can completely replace fall-preventing facilities such as an existing security clamp.

    本发明公开了一种新型的防电梯坠落结构,包括井道和轿厢升降机构,所述井道内设有轿厢,井道内设有位于轿厢移动路径一侧且横向凸出于井道内壁的承托部;所述轿厢上设有能相对其横向移动并被所述承托部支撑的防坠架,轿厢与防坠架之间连接有横移驱动装置。还公开了一种新型的防电梯坠落结构的防坠落方法,所述轿厢沿着井道上下移动时,所述防坠架相对轿厢横移避开井道内的承托部;当防坠架位于一个承托部上方时,防坠架横移至与该承托部位于同一侧。本发明提供的新型的防电梯坠落结构及其防坠落方法,不仅无需设置井道基坑,适用性广,且能避免轿厢出现较大高度的下坠,安全性高,稳定性好,能完全取代现行的安全钳等防坠落设施。
