The invention discloses a counterweight side-falling elevator structure. The structure is characterized in that a traction steel wire rope enters a first counterweight rope return wheel arranged at the top end of the rear part of a counterweight through a traction machine wheel and a machine room guide wheel, enters a first counterweight guide wheel after being guided by the first counterweight rope return wheel and is horizontally and forwards transmitted into a second counterweight guide wheel, and the second counterweight guide wheel is used for ensuring that the traction steel wire rope vertically falls into a second counterweight rope return wheel arranged at the top end of the front part of the counterweight and is finally suspended to a counterweight rope head bearing beam. According to the arrangement mode, the traction steel wire rope enters the two counterweight rope return wheels arranged at the upper end of the counterweight from the adjacent side, the counterweight can move backwards by a distance equal to the diameter of the counterweight rope return wheel, so that the counterweight is placed in the middle in the front-back direction as much as possible, the counterweight is far away from a car door plate assembly located on the front side of an elevator car as much as possible, the safety space between the counterweight and a hoistway, the elevator car and the car door plate assembly is guaranteed, and even if the traction machine wheel and the machine room guide wheel are not placed obliquely, the distance between the counterweight and the car door plate assembly can be larger than the safety distance.

    本发明公开了一种对重侧落电梯结构,曳引钢丝绳经曳引机轮和机房导向轮进入设置于对重后部顶端的第一对重返绳轮,经第一对重返绳轮导向后进入第一对重导向轮水平向前传入第二对重导向轮,第二对重导向轮用于保证曳引钢丝绳垂直落入设置于对重前部顶端的第二对重返绳轮,最后悬挂到对重绳头承重梁,此布置方式通过曳引钢丝绳从邻接侧进入设置在对重上端的两个对重返绳轮,使得对重位置可以后移一个对重反绳轮直径的距离,使对重尽量处于前后方向居中放置,使对重尽量远离位于电梯轿厢前侧的轿门板组件,保证对重与井道、电梯轿厢及轿门板组件的安全空间,即便曳引机轮和机房导向轮不倾斜放置,也能使对重同轿门板组件的距离大于安全距离。
