Protective device and method suitable for bridge sling viscoelastic vibration reduction frame
The invention discloses a protection device and method suitable for a bridge sling viscoelastic vibration reduction frame. The protection device comprises a protection part and a test part. The protection part comprises a waterproof protection shell, a sheath and a telescopic tent; a waterproof coating is laid in the shell, and the shell extends outwards to form an eave edge and is tightly engaged with the edge of the sheath; the shells are connected with the telescopic awning through the protrusions and the grooves, and the telescopic awning can achieve self-adaptive deformation according to the relative position change of the shells on the two sides. The testing part comprises an acceleration sensor which can collect vibration responses of the sling in the longitudinal bridge direction and the transverse bridge direction at the position of the vibration reduction frame. Through cooperative work of the waterproof protection shell, the sheath, the telescopic awning and the waterproof coating, the device can enable the interior of the shell to form a closed cavity, the influence of rainwater, solar radiation and other factors on the viscoelastic vibration reduction frame is isolated, and the service life of the viscoelastic vibration reduction frame is greatly prolonged; meanwhile, the acceleration sensor can monitor vibration responses of multiple positions on the sling, so that the motion state of the sling is described more accurately, and the vibration rule of the sling is mastered.
本发明公开了一种适用于桥梁吊索粘弹性减振架的防护装置及方法。防护装置包括防护部分和测试部分。防护部分包括防水保护壳、护套、伸缩篷；壳体内部铺设防水涂层，壳体向外延伸出檐边并与护套边缘紧密咬合；壳体与伸缩篷间通过凸起与凹槽连接，伸缩篷可根据两侧壳体的相对位置变化实现自适应变形。测试部分包括加速度传感器，能够采集吊索在减振架位置纵桥向、横桥向的振动响应。通过防水保护壳、护套、伸缩篷、防水涂层的协同工作，该装置能够使得壳体内部形成密闭空腔，隔绝雨水、太阳辐射等因素对粘弹性减振架的影响，大幅延长其使用寿命；同时加速度传感器可监测吊索上多位置的振动响应，从而更准确地描绘吊索运动状态，掌握其振动规律。
