The invention discloses an emergency buffer device capable of preventing a lift car from rushing to the top and an elevator using the emergency buffer device. The emergency buffer device comprises an elevator derrick, a mounting seat, a servo motor, a power shaft and the like. The mounting seat is fixedly mounted on the right side of the top face of the elevator derrick, the servo motor is fixedly mounted on the mounting seat, and the power shaft is welded to the left end of an output shaft of the servo motor. Speed reduction calipers make contact with the power shaft, the speed reduction calipers exert resistance on the power shaft, so that the rotating speed of the power shaft and the rotating speed of devices on the power shaft are gradually decreased, meanwhile, through the effect of a first compression spring, a shifting clamping rod limits a movable limiting wheel, the rotating speed of the movable limiting wheel is decreased, the lifting speed of the lift car is decreased, then the lift car can stop in the gradual deceleration process, and the phenomenon that the lift car ascends too fast and rushes to the top when the braking effect of a brake is insufficient is prevented.

    一种能够预防轿厢冲顶的紧急缓冲装置及选用该装置的电梯,包括有电梯井架、安装座、伺服电机、动力轴等;电梯井架顶面右侧固定安装有安装座,安装座上固定安装有伺服电机,伺服电机输出轴左端焊接有动力轴。通过降速卡钳与动力轴相互接触,降速卡钳对动力轴造成阻力,使得动力轴及其上装置转动速度逐渐减慢,同时通过压缩弹簧一的作用,使拨动卡杆对活动限制轮进行限制,使得活动限制轮转动速度减缓,从而使电梯轿厢升降速度得到减缓,进而电梯轿厢在逐渐减速过程会停止,防止制动器的制动效果不足时电梯轿厢上升速度过快而发生冲顶现象。
