The invention relates to an elevator car lifting device and an elevator, and relates to the technical field of elevator equipment. The device comprises a multi-stage telescopic arm and a driving assembly, the multi-stage telescopic arm comprises a plurality of arm barrels which are arranged in a sleeving mode stage by stage from outside to inside, the inner diameters of the arm barrels are gradually reduced, and first traction ropes are wound around the top ends of all the stages of arm barrels located between the first-stage arm barrel and the last-stage arm barrel; the two ends of the first traction rope are connected with the previous-stage arm cylinder and the next-stage arm cylinder of the corresponding arm cylinders correspondingly, the first-stage arm cylinder is used for being fixed to an elevator shaft, and the last-stage arm cylinder is used for being connected with a lift car; the driving assembly is configured to be used for driving the second-stage arm barrel to move telescopically. The length of the hydraulic cylinder is supplemented through the multi-stage telescopic arm, so that the hydraulic cylinder can drive the lift car to move by multiple distances under the fixed cylinder body length, and the occupied space needed by the hydraulic cylinder is saved.
本申请涉及一种电梯轿厢升降装置及电梯,涉及电梯设备技术的领域的领域。其包括多级伸缩臂和驱动组件,多级伸缩臂包括若干由外向内逐级套设且内径逐渐减小的臂筒,位于第一级和最后一级臂筒之间的各级臂筒顶端均绕设有第一牵引绳,第一牵引绳两端分别与其对应的臂筒的前一级臂筒和后一级臂筒相连,第一级臂筒用于与电梯井固定,最后一级臂筒用于与轿厢相连;驱动组件被配置为用于驱动第二级臂筒伸缩移动。本申请通过多级伸缩臂补充了液压缸的长度,使得液压缸在固定的缸体长度下能够驱使轿厢移动多倍的距离,节省了液压缸所需占用空间。
