The invention discloses a double-layer elevator guide rail, and belongs to the technical field of elevator equipment. The double-layer elevator guide rail comprises a basic assembly, wherein a driving assembly is arranged at the top of the basic assembly, the bottom end of the driving assembly is movably connected with the bottom of a supporting assembly through a linkage assembly, the linkage assembly is located in the basic assembly, and the top end of the supporting assembly is fixedly connected with a connecting assembly. According to the invention, through mutual cooperation of the designed structures such as the driving assembly, the linkage assembly, the supporting assembly and the joining assembly, the width of a gap at a joint for preventing expansion caused by heat and contraction caused by cold of a first steel rail and a second steel rail is not affected, the generation of vibration is effectively reduced, the service life of the first steel rail and the second steel rail is prolonged, the stability of the second steel rail and the first steel rail in the working process is improved, resonance between the first steel rail and the second steel rail is avoided, the matching degree of the butt joint of the first steel rail and the second steel rail is effectively guaranteed, and collision between a guide shoe and the first steel rail or the second steel rail is avoided.

    本发明公开了一种双层电梯导轨,属于电梯设备技术领域,包括基础组件,所述基础组件的顶部设置有驱动组件,所述驱动组件的底端通过联动组件与支撑组件的底部活动连接,并且联动组件位于基础组件的内部,所述支撑组件的顶端固定连接有衔接组件。本发明中,通过设计的驱动组件、联动组件、支撑组件以及衔接组件等结构的互相配合下,因而便不会影响为防止第一钢轨和第二钢轨热涨冷缩的接头处缝隙的宽度,有效降低了震动的产生,提高了第一钢轨及第二钢轨的使用寿命以及第二钢轨及第一钢轨在工作过程中的稳定性,避免第一钢轨和第二钢轨之间引发共振,有效保证了第一钢轨与第二钢轨对接处的吻合度,避免导靴与第一钢轨或第二钢轨形成撞击。
