The invention provides an elevator without a bottom pit. The elevator comprises an elevator car, buffers, a speed limiter rope tensioning device, a guide shoe, a safety space, a foot guard and a weight induction device. The elevator car is arranged in an elevator shaft, the buffers are arranged in an elevator pit, when the elevator car is located on the bottommost layer, the speed limiter rope tensioning device is arranged to be higher than the bottom plane of the elevator car, the safety space is arranged behind the elevator shaft, the foot guard is arranged below a sill of the elevator car,and the weight induction device is arranged at the bottom of the elevator pit. The first buffer, the second buffer, the third buffer and the fourth buffer are all arranged in the elevator pit, when the elevator car collapses, acting fulcrums of the four buffers are located at the positions of the four endpoints outside the elevator car correspondingly, the space can be vacated, the elevator car can conveniently reach a lower position, thus, the requirement for the depth of the elevator pit is lowered, the retrofitting cost of the elevator is reduced, and the elevator is safer and more reliable.
本申请提供一种无底坑电梯,包括电梯轿厢、缓冲器、限速器涨绳装置、导靴、安全空间、护脚板、重量感应装置,电梯轿厢设置在电梯井道内部,缓冲器设置在电梯地坑内,当电梯轿厢位于最底层时,限速器涨绳装置的设置高于电梯轿厢的底平面,安全空间设置在电梯井道的后方,护脚板设置在电梯轿厢地坎下方,重量感应装置设置在电梯地坑的底部。本申请的第一缓冲器、第二缓冲器、第三缓冲器和第四缓冲器均设置在电梯地坑内,且电梯轿厢蹲底时,四个缓冲器的作用支点分别为电梯轿厢外部的四个端点处,可以腾出空间,以便电梯轿厢可以到达更低的位置,从而降低对电梯地坑深度的要求,减少电梯加装成本,更加安全可靠。
