The invention discloses a high-speed elevator tensioning device. According to the high-speed elevator tensioning device, the problem that a tensioning device vibrates in the vertical direction under the emergency braking working condition of an existing elevator is solved through a damping assembly. When the elevator is braked emergently, upward pulling and throwing force is generated on the tensioning device, a damping rod is driven to move through the pulling and throwing force, a buffer plate A, a buffer plate B and a buffer plate C move, a spring A, springs B, a spring C, a spring D and springs E deform, and impact energy generated during emergency braking is converted into kinetic energy and elastic potential energy. The problem that the tensioning device is clamped due to the fact that the swing amplitude of an existing steel wire rope in the horizontal direction is too large is solved through the adjusting assembly. An adjusting motor drives a driving rod to rotate, a driving ring moves in the central axis direction of the driving rod, an adjusting base moves in an adjusting frame while moving along with the driving ring, the adjusting rod is driven to move, and therefore the distance between an adjusting wheel and a steel wire rope is changed.
本发明公开了一种高速电梯张紧装置,本发明通过减震组件解决了现有电梯在紧急制停工况下,张紧装置在垂直方向上会产生颤动的问题;当电梯紧急制停时,对张紧装置产生向上的拉抛力,通过拉抛力带动减震杆运动,缓冲板A、缓冲板B、缓冲板C运动,弹簧A、弹簧B、弹簧C、弹簧D、弹簧E发生变形,将紧急制停时的冲击能量转化为动能、弹性势能。通过调节组件解决了现有钢丝绳在水平方向上存在摆幅过大造成张紧装置卡柱的问题;通过利用调节电机带动驱动杆转动,驱动环沿驱动杆中心轴线方向移动,调节座随驱动环运动的同时在调节框内移动,带动调节杆运动,从而改变调节轮与钢丝绳之间的距离。
