The invention discloses a traction-driven machine-room-free elevator. The traction-driven machine-room-free elevator comprises a lift car, lift car guide rails, lift car surrounding walls, a lift car frame front beam, a counterweight block, a counterweight support side plate and a double-wheel traction machine. A first groove is formed in the side wall, facing the lift car, of the counterweight block, a second groove and a third groove are formed in the counterweight support side plate and the lift car surrounding walls respectively, the compactness degree of the counterweight block, the counterweight support side plate and the lift car surrounding walls is improved, and then the purpose of saving the shaft space is achieved; and meanwhile, due to the fact that the second groove is formed in the counterweight support side plate, the installation space is vacated for the lift car guide rails, and the lift car guide rails can be fixed through bolt assemblies with the larger size and strength. The traction-driven machine-room-free elevator is an important technical scheme for reducing the shaft width space to the maximum degree; due to the fact that the thickness space of the lift car surrounding walls on the two sides and the operation space of a counterweight device are fully utilized for configuring elevator components, the shaft utilization rate is greatly increased.

    本发明公开了一种曳引驱动无机房电梯,其包括轿厢、轿厢导轨、轿厢围壁以及轿架前梁,对重块、对重支架侧板、双轮曳引机。在对重块朝向轿厢的侧壁上设置第一凹槽,在对重支架侧板以及轿厢围壁上分别形成第二凹槽和第三凹槽,提高了对重块、对重支架侧板以及轿厢围壁的紧凑程度,进而达到节省井道空间的目的,同时由于对重支架侧板上形成第二凹槽,为轿厢导轨腾出了安装空间,能够采用更大尺寸和强度的螺栓组件对其进行固定,是本发明最大化减小井道宽度空间的重要技术方案,由于充分利用了两侧轿厢围壁的厚度空间和对重装置运行空间配置电梯部件,极大的提升了井道利用率。
