The invention relates to the technical field of elevators, and discloses an elevator overspeed protection mechanism which comprises an elevator shaft, a lift car, a winding machine and a steel wire rope, the lift car is slidably installed in the elevator shaft, the winding machine is installed at the top end of the elevator shaft, the steel wire rope is fixedly installed at the top end of the lift car, and the top end of the steel wire rope is fixed to a winding shaft on the winding machine. A speed monitor is installed at the top end of the elevator shaft, and a controller and a double-shaft motor are installed at the top end of the elevator shaft. A first arc-shaped friction plate can be extruded to move through movement of a U-shaped block, then the moving speed of a pull rope is reduced, then the moving speed of a lift car is reduced, meanwhile, a push rod can be driven to move through rotation of a screw rod, then strip-shaped rods on the left side and the right side are pushed to move, and a conical friction plate is attached to the lift car; and a moving block can be pulled to move through movement of a pull rope, then an arc-shaped friction plate II moves to be attached to a rotating shaft, and the rotating speed of the winding machine is reduced.

    本发明涉及电梯技术领域,且公开了一种电梯超速保护机构,包括电梯井、轿厢、收卷机和钢丝绳,所述电梯井内部滑动安装有轿厢,所述电梯井顶端安装有收卷机,所述轿厢顶端固定安装有钢丝绳,且钢丝绳顶端固定在收卷机上的收卷轴上,且钢丝绳缠绕在收卷轴上,所述电梯井顶端安装有速度监测器,所述电梯井顶端安装有控制器和双轴电机。本发明不仅能够通过U型块移动挤压弧形摩擦片一移动,进而使得拉绳的移动速度降低,进而降低了轿厢的移动速度,同时能够通过螺杆转动带动推杆移动,进而推动左右两侧的条型杆移动,使得锥形摩擦片与轿厢贴合,还能够通过拉绳移动拉动移动块移动,进而使得弧形摩擦片二移动与转动轴贴合,降低收卷机的转动速度。
