Bridge cable wind-induced vibration control alarm
The invention relates to the field of bridge cable vibration alarm, and particularly discloses a bridge cable wind-induced vibration control alarm which comprises a protective cylinder, a monitoring alarm unit and a vibration control unit. The protective cylinder is fixedly sleeved on an inhaul cable of a bridge; the monitoring alarm unit comprises an acceleration sensor and a plurality of laser detectors, the acceleration sensor is arranged on the protective cylinder, each laser detector comprises a laser emitting part, a laser receiving part and an alarm part, the alarm part is arranged on a main beam of the bridge, and the alarm part comprises a signal emitting module; the vibration control unit comprises a vibration control base arranged on the cable bent tower, a rope winder, a control ring and a control rope are arranged on the vibration control base, the control rope is wound on the rope winder and connected with the control ring, the control ring is slidably arranged on the protection cylinder, and a fixing nail is arranged on the inner wall of the control ring. And a fixing hole for inserting the fixing nail is formed in the protective cylinder. The objective of the invention is to solve the technical problems of how to alarm vibration of the inhaul cable and how to control vibration of the inhaul cable.
本发明涉及桥梁拉索振动报警领域，具体公开了一种桥梁拉索风致振动控制报警器，包括保护筒、监测报警单元和振动控制单元；保护筒固定套设在桥梁的拉索上；监测报警单元包括加速度传感器和若干激光检测器，加速度传感器设置在保护筒上，激光检测器包括激光发射部、激光接收部和报警部，报警部设置在桥梁的主梁上，报警部包括信号发射模块；振动控制单元包括设置在索塔上的振动控制底座，振动控制底座上设置有卷绳器、控制环和控制绳，控制绳卷绕在卷绳器上，控制绳与控制环连接，控制环滑动设置在保护筒上，控制环的内壁设置有固定钉，保护筒上设置有供固定钉插入的固定孔。本发明的目的在于解决如何对拉索振动进行报警以及控制拉索振动的技术问题。
