The invention discloses an elevator falling speed reducer. The elevator falling speed reducer comprises a shaft, an elevator is slidably connected into the shaft, a cable capable of controlling the elevator to ascend and descend is connected to the upper side of the elevator, an elevator car used for taking passengers and goods is arranged in the elevator, and an elevator door connected to the left side of the elevator car is arranged in the elevator. Compared with a traditional elevator, firstly, disinfection can be carried out when no person or goods exist in the elevator car, disinfection is stopped after people or goods enter the elevator car, and therefore sanitation in the elevator car is guaranteed; and through the difference value of the rotating speeds of two shafts, the situation that the elevator descends too fast is judged, the speed reduction blocks on the two sides are driven to move to be tightly attached to the inner wall of the shaft, the descending speed of the elevator is reduced, personnel in the elevator car are protected, and losses caused by elevator faults are reduced.
本发明公开的一种电梯下坠减速装置,包括井道,所述井道内滑动连接有电梯,所述电梯上侧连接有能控制所述电梯升降的缆绳,所述电梯内设有用于搭乘乘客以及货物的轿厢,所述电梯内设有连接于所述轿厢左侧的电梯门,本发明相比于传统的电梯,首先,本发明能在轿厢内无人或货物时进行消毒,且在轿厢内进入人以及货物后停止消毒,从而保证轿厢内的卫生,其次,本发明能在电梯发生故障快速下降时,通过两根轴之间转速的差值从而判断出电梯下降过快并带动两侧的减速块移动来紧贴井道内壁从而减缓电梯的下降速度来保护轿厢内的人员,并减小电梯故障打来的损失。
