According to the elevator without the machine room, a lift car can ascend and descend in a hoistway, and a lift car diversion sheave is arranged at the bottom of the lift car; the traction device is used for being installed on a hoistway and located on the side face of the lift car. The counterweight is arranged on the rear side of the lift car, two counterweight diversion sheaves are arranged on the counterweight, and rope outlet points of the counterweight diversion sheaves are located outside the projection of the counterweight; and the steel wire rope is sequentially wound on the lift car diversion sheave, the traction device and the counterweight diversion sheave. Due to the fact that the counterweight is arranged on the rear side of the hoistway, the width size of the hoistway can be saved, the width of the hoistway is reduced, the elevator without the machine room can be suitable for buildings with narrow hoistways, in addition, the elevator without the machine room can save fixed pulleys installed at the bottom and the top of the hoistway respectively, and the cost is reduced. The rope winding structure is simpler, the steel wire rope is short in length and low in cost, the bending frequency of the steel wire rope is small, the service life is prolonged, and the running stability of an elevator is improved.

    本发明涉及一种无机房电梯,包括:轿厢能够在井道内升降运行,轿厢的底部设置有轿厢反绳轮;曳引装置用于安装在井道上并位于轿厢的侧面;对重设置于轿厢的后侧,对重上设置有两个对重反绳轮,对重反绳轮的出绳点位于对重的投影以外;以及钢丝绳依次绕装于轿厢反绳轮、曳引装置和对重反绳轮上。由于对重布置在井道后侧,因而可节省井道宽度尺寸,使井道宽度得以降低,进而使无机房电梯能够适用于井道宽度较窄的建筑物中,此外,本方案的无机房电梯还能够省去以对分别安装在井道底部和井道顶部的定滑轮,不仅使绕绳结构更加简单,钢丝绳长度短,成本低,并且钢丝绳的折弯次数少,有助于提高使用寿命,提升电梯运行平稳度。
