The invention discloses a novel household screw platform elevator. The novel household screw platform elevator comprises a guide rail base, a guide rail, two rows of bearing channel steel, a tensioning wheel, a steel belt rope end, a backpack frame, a platform guide shoe, a platform frame, a platform plate, a safety clamp braking device, a motor, a coupler, a motor mounting plate assembly, a lowerbearing seat, a lower guide wheel assembly, a sliding guide shoe, a screw, a limit protector, an upper guide wheel assembly, a screw upper fixing frame, an upper bearing seat, a speed limiter and aninner curtain wall. According to the novel household screw platform elevator, when the motor rotates, the screw is driven to rotate, two positive and negative nuts mounted on the screw do linear motion to drive the upper and lower guide wheels connected with the nuts to do relative motion, so that the steel belt wound on the guide wheels is dragged to retract or release, and the retracting or releasing distance of the steel belt is four times of the relative operation distance of the positive and negative nuts; and the use length of the screw is greatly shortened, so that the production and maintenance costs are greatly reduced.
本发明公开了一种新型家用螺杆平台电梯,包括:导轨底座、导轨、两列承重槽钢、涨紧轮、钢带绳头、背包架、平台导靴、平台架、平台板、安全钳制动装置、电机、联轴器、电机安装板组件、下轴承座、下导向轮组件、滑动导靴、螺杆、极限保护器、上导向轮组件、螺杆上固定架、上轴承座、限速器、内幕墙。本发明电机转动时驱动螺杆转动,安装在螺杆上的两个正反螺母作线性运动,带动跟螺母连接的上下导向轮也作相对运动,从而拽拉缠绕在导向轮上的钢带收缩或释放,钢带收缩或释放的距离是正反螺母相对运行距离的4倍,大大缩短了螺杆的使用长度,从而大幅度降低了生产及维护成本。
