The invention discloses a telescopic car door sill and a telescopic control method, and relates to the technical field of elevator sills. The elevator comprises a lift car, a car door sill and a landing door sill, the car door sill is arranged on one side of the lift car, a gap exists between the car door sill and the landing door sill, a fixing plate is arranged on one side of the lift car, a transverse moving rod is arranged on the fixing plate in a sliding mode, a pedal is arranged on the transverse moving rod, and the pedal is in abutting lap joint with the car door sill and the landing door sill. When the lift car runs, the rotating rod is driven to rotate through the driving part, kinetic energy of rotation of the rotating rod is stored through the power part, when the lift car stops running, the stored kinetic energy is transmitted to the rotating shaft through the power part and drives the rotating shaft to rotate, the shaft rod is driven to intermittently rotate through the transmission part, and the transverse moving rod is driven to slide in the horizontal direction through the driving part; the pedal is driven to move together until the pedal abuts against and is in lap joint with the landing door sill, the phenomenon that sundries fall into a hoistway from a gap, and consequently equipment is damaged is avoided, and potential safety hazards caused by the gap are eliminated.
本申请公开了可伸缩的轿门地坎及伸缩控制方法,涉及电梯地坎技术领域。本申请包括轿厢、轿门地坎以及层门地坎,轿门地坎设置在轿厢的一侧且与层门地坎之间存在间隙,轿厢的一侧设置有固定板,固定板上滑动设置有横移杆,横移杆上设置有踏板,踏板与轿门地坎以及层门地坎均抵触搭接。本申请在轿厢运行时,通过驱动件驱使转杆转动,通过动力件将转杆转动的动能进行储存,当轿厢停止运行时,通过动力件将储存的动能传递至转轴并驱使其转动,通过传动件驱使轴杆间歇性转动,通过驱动部驱使横移杆沿水平方向滑动,带动踏板一同运动,直至踏板与层门地坎抵触搭接,避免从间隙掉落杂物进入井道,造成设备损坏的现象,消除了因间隙而带来的安全隐患。
