The invention discloses a movable nut and screw rod power construction lifting platform which comprises a guide rail, a screw rod, a screw rod support, a motor, a motor support, a coupler, a nut support and a nut, the screw rod and the motor are connected through the coupler, the screw rod and the motor are fixed to an outer guide rail through the screw rod support and the motor support, the nut support is fixed to an inner guide rail, and the nut support is fixed to an outer guide rail. The nut is in threaded connection with the lead screw, the rotation angle of the nut in the nut support is smaller than 360 degrees, when the lead screw moves relative to the nut, the nut downwards presses the nut support when the lead screw rotates the outer guide rail to ascend, and the nut makes contact with the plane of the lower bottom plate. When the lead screw rotates and the inner guide rail ascends, the nut upwards abuts against the nut support and makes contact with the plane of the upper bottom plate. If the inner guide rail or the outer guide rail moves forwards, backwards, leftwards and rightwards when the construction lifting platform ascends and descends, torsion of the lead screw can drive the nut to move on the contact face of the nut support, the nut is automatically adjusted to be in the state of coinciding with the axis of the lead screw, and normal crawling of the guide rail is guaranteed.

    本发明公开了一种可移动螺母丝杆动力的施工升降平台,包括导轨、丝杆、丝杆支架、电机、电机支架、联轴器、螺母支架、螺母,所述丝杆和电机通过联轴器连接,所述丝杆、电机通过丝杆支架、电机支架和外导轨固定,所述螺母支架与所述内导轨固定,所述螺母与所述丝杆螺纹连接,所述螺母在所述螺母支架内旋转角度小于360°,当丝杆相对于螺母运动时,在丝杆旋转外导轨上升时螺母向下压住螺母支架,螺母与下底板平面接触。在丝杆旋转内导轨上升时螺母向上顶住螺母支架,螺母与上底板平面接触。如果在施工升降平台升降时出现内导轨或外导轨前后左右移动,则丝杆的扭力会带动螺母在所述螺母支架接触面移动,实现螺母自调整到与丝杆轴心重合的状态,保证导轨的正常爬行。
