The invention discloses a speed limiter rope tensioning device. A first pulley and a second pulley are adjacent and are arranged on a same main shaft with a gap, and the first pulley and the second pulley can independently and freely rotate around the main shaft; the first pulley and the second pulley can be fastened together through a fastener so as to synchronously and freely rotate around the main shaft in the same direction; a speed limiter rope is wound by at least one circle in a rope cavity of the first pulley and a rope cavity of the second pulley respectively, one end of the speed limiter rope is wound out of the rope cavity of one of the first pulley and the second pulley in the clockwise direction, and the other end of the speed limiter rope is wound out of the rope cavity of the other of the first pulley and the second pulley in the anticlockwise direction. The invention further discloses a using method of the speed limiter steel wire rope tensioning device. The device can ensure that the rope releasing action of the speed limiter rope is automatically realized when a jumping elevator machine room jumps, and high safety and comfort and low cost are achieved.
本发明公开了一种限速器绳张紧装置,第一滑轮、第二滑轮相邻并有间隙安装在同一主轴上,第一滑轮、第二滑轮能分别独立绕主轴自由转动;第一滑轮、第二滑轮并能通过紧固件紧固到一起,从而同步同向绕主轴自由转动;限速器绳在第一滑轮的绳腔、第二滑轮的绳腔分别绕有至少一圈,限速器绳的一端按顺时针方向绕出第一滑轮、第二滑轮之中的一个滑轮的绳腔,限速器绳的另一端按逆时针方向绕出第一滑轮、第二滑轮之中的另一个滑轮的绳腔。本发明还公开了该限速器钢丝绳张紧装置的使用方法。本发明既可保证跃升电梯机房跃升时自动实现限速器绳的放绳动作,又具有较高的安全性、舒适性,而且成本低。
