The invention provides an external electromechanical floor lifting step. C-shaped rails are laid along the two sides of a stair, openings of the left rail and the right rail correspond to each other, two rail wheels are arranged in each of the left rail and the right rail, spindles of the rail wheels are fixed to the two sides of the step and mainly bear the step to slide up and down in the rails, and handrails are arranged at the upper ends of the two sides of the step. An intelligent box and a lifting switch are installed at the upper ends of the handrails, U-shaped wheels are installed on the left side, on the right side and in the middle of the step, a motor is arranged in an accessory box of a wall surface above the stair, an intelligent alarm and a fire extinguisher are additionally installed in the accessory box, a roller is installed at the front end of the motor and connected with a steel wire rope, the steel wire rope extends in the left rail through a guide wheel and is inserted into grooves of left U-shaped wheel, the middle U-shaped wheel and the right U-shaped wheel, and the three U-shaped wheels are in an inverted triangle shape. Balance and stability of the step can be kept during up and down sliding, the tail end of the steel wire rope is connected to a fixing pin at the top end of the right rail, remote control switches are correspondingly installed on the wall faces above and below the stair, and the whole up-down sliding process of the step is completed by driving the roller to drag the steel wire rope through the motor and under supporting of two rail wheels.
沿楼梯两侧铺设C型轨道,左右轨道的开口相对应,左右轨道内各配置两只轨道轮,轨道轮的主轴固定在踏步的两侧,主要承载踏步在轨道内上下滑动,踏步两侧上端装有扶手,扶手顶端装有智能盒和升降开关,踏步左右两侧和中间装有U型轮,电动机装在楼梯上方墙面的配件箱内,配件箱内另装有智能报警器和灭火器,电动机前端装有滚筒,滚筒连接钢丝绳,钢丝绳通过导向轮在左轨道中延伸并穿插在左、中、右U型轮的凹槽内,三个U型轮呈倒三角形状,可保持踏步上下滑动时的平衡和稳定,钢丝绳的尾端连接在右轨道顶端的固定销上,楼梯上下方墙面上各装有遥控开关,踏步的整个上下滑动过程由电动机带动滚筒拖拽钢丝绳以及在两轨道轮的支撑下完成。
