The invention relates to an elevator hoistway arrangement structure. The elevator hoistway arrangement structure comprises a counterweight system, a lift car system and a traction machine which are arranged in an elevator hoistway, the traction machine is used for driving a lift car of the lift car system to ascend and descend, the counterweight system comprises counterweight guide rails, a counterweight frame, a speed limiter, a speed limiter steel wire rope and a tensioning device, the counterweight frame can ascend and descend in the counterweight guide rails, and a counterweight lifting device is arranged at the bottom of the counterweight frame; a main machine beam used for installing the traction machine is arranged at the tops of the counterweight guide rails, and the speed limiteris arranged above the traction machine or installed on the main machine beam side by side with the traction machine; from the overlooking angle, the side, close to the main machine beam, of the speedlimiter coincides with the main machine beam, and the coinciding area exceeds half of the cross sectional area of the speed limiter; and the upper part of the speed limiter steel wire rope winds around the speed limiter, the lower part of the speed limiter steel wire rope winds around the tensioning device, and the joint is connected with the counterweight lifting device to form a closed chain. The transverse space width occupied by the speed limiter can be reduced, and therefore the design of the hoistway width can be reduced, and the hoistway plane utilization rate is increased.

    本发明涉及一种电梯井道布置结构,包括设置在电梯井道内的对重系统、轿厢系统和曳引机,曳引机用于带动轿厢系统的轿厢升降移动,对重系统包括对重导轨、对重架、限速器、限速器钢丝绳和张紧装置,对重架可在对重导轨内升降移动,对重架底部设有对重提拉装置;对重导轨顶部设有用于安装曳引机的主机梁,限速器设置于曳引机上方或与曳引机并排安装于主机梁上;从俯视角度看,限速器靠近主机梁的一侧部分与主机梁重合,且重合面积超过限速器横截面积的一半;限速器钢丝绳上绕限速器,下绕张紧装置,接合处与对重提拉装置连接形成封闭的链。能够减少限速器占用横向空间宽度,从而可缩小井道宽度的设计,提高井道平面利用率。
