The invention relates to the technical field of elevators, in particular to a rolling guide shoe capable of changing a fulcrum and a backpack type elevator. The rolling guide shoe comprises a guide shoe seat, a first roller, a second roller and a rotating shaft; the first roller is mounted on one end surface of the guide shoe seat; the second roller is mounted on the other end surface, opposite tothe first roller, of the guide shoe seat; and the rotating shaft is arranged between the first roller and the second roller, and the distance between the center of the rotating shaft and the center of the second roller is shorter than the distance between the center of the rotating shaft and the center of the first roller, so that a first deformation amount generated after the first roller is stressed is converted into a first amplitude value at the rotating shaft through a physical principle, and a second deformation amount generated after the second roller is stressed is converted into a second amplitude value at the rotating shaft through the physical principle, wherein the first amplitude value is the same as or close to the second amplitude value. The rolling guide shoe capable of changing the fulcrum and the backpack type elevator have the beneficial effect that vibration and noise phenomena caused by surface deformation of the first roller and the second roller due to long-termparking of the backpack type elevator can be effectively relieved.

    本发明涉及电梯技术领域,尤其涉及一种改变支点的滚动导靴及背包式电梯,其中,包括:一导靴座;一第一滚轮,安装于导靴座的一端面;一第二滚轮,安装于导靴座的与第一滚轮对立的另一端面;一旋转轴,设置于第一滚轮和第二滚轮之间,且旋转轴的中心与第二滚轮的中心的距离比旋转轴的中心与第一滚轮的中心的距离短,以使得第一滚轮受力后产生的一第一变形量通过一物理原理折算成在旋转轴处的一第一振幅值与第二滚轮受力后产生的一第二变形量通过物理原理折算成在旋转轴处的一第二振幅值相同或接近。有益效果:可有效地减缓背包式电梯由于长期停放导致第一滚轮和第二滚轮表面变形引起的振动和噪音现象。
