The invention discloses a back-covered portal-frame elevator. The elevator comprises a shaft, a car rope head beam, a car top wheel, an auxiliary vertical beam, a car, a counterweight guide rail, a counterweight device, a car guide rail, a car bottom component, a vertical beam, a car top framework component, a carrying beam, a drag wheel and a rack, wherein the carrying beam is arranged behind thetop of the shaft, and the car rope head beam is arranged in front of the top of the shaft. According to the elevator, the counterweight guide rail, the counterweight device and the car guide rail areall arranged behind the car, so that the sightseeing range of the car is expanded; the car can be opened at one side or two sides or three sides, so that the practicability of the elevator is improved; the traditional structure that elevator guide rails are arranged at two sides of a car is changed, the guide rails are oppositely arranged behind the car, and the phenomenon of tilting, caused by non-symmetrical and non-vertical tracks, of the tracks, a counterweight device and a car is avoided; and according to the arrangement structure of the vertical beam, car guide rail spacing is reduced,so that clear width of the shaft is reduced, a lower beam is not arranged at the bottom of the car, the width of the shaft is reduced, and cost is lowered.
本发明公开了一种背包龙门架式电梯,包括井道、轿厢绳头梁、轿顶轮、副立梁、轿厢、对重导轨、对重装置、轿厢导轨、轿底组件、立梁、轿顶框架组件、搁机梁、曳引轮和机架,所述井道顶部后方设有搁机梁,前方设有轿厢绳头梁,利用将对重导轨、对重装置和轿厢导轨均设在轿厢后方,增大了轿厢的观光面,且使轿厢在单面开门,两面开门和三面开门中均能应用,提高了其实用性,改变传统电梯导轨设于轿厢两侧的结构,使其导轨对立设在轿厢后方,避免出现轨道不对称不垂直,所导致的轨道倾斜、对重装置和轿厢倾斜的现象发生,根据立梁设置结构,减小轿厢导轨距,从而缩小井道净宽,轿底无下梁,降低井道宽度,降低了成本。
