Bridge tower crane damping extension arm connection
The invention relates to a bridge tower and tower crane damping outrigger connection for bridge tower vibration reduction during construction, which comprises a bridge tower structure body, a tower crane body for bridge tower construction and one or more outrigger trusses, one end of each outrigger truss is fixed on the bridge tower structure body, the other end of each outrigger truss is provided with a plurality of first spherical hinges, the tower crane body is provided with a bracket, and the bracket is provided with a plurality of second spherical hinges. The bracket is provided with a plurality of second spherical hinges, the second spherical hinges correspond to the first spherical hinges in a one-to-one mode, vertical dampers are connected between the second spherical hinges and the corresponding first spherical hinges, and the second spherical hinges are located below the vertical direction of the corresponding first spherical hinges. Compared with the prior art, the tower crane has the advantages that bending corner deformation of the bridge tower is restrained through the tower crane body and the damper, the effect of restraining vibration of the construction bridge tower under the action of dynamic loads such as wind or reducing the amplitude is achieved, and the safety and constructability of the construction bridge tower are guaranteed.
本发明涉及一种用于施工期间桥塔减振的桥塔塔吊阻尼伸臂连接，包括桥塔结构本体和用于桥塔施工的塔吊塔身，以及一个或多个伸臂桁架，伸臂桁架的一端固定于桥塔结构本体上，另一端设置有多个第一球铰，塔吊塔身上设置有牛腿，牛腿上设有多个第二球绞，各第二球绞与各第一球铰一一对应，且各第二球绞与其对应第一球铰之间连接有竖向阻尼器，且各第二球绞位于其对应第一球铰的竖直方向下方。与现有技术相比，本发明具有利用塔吊塔身和阻尼器抑制桥塔的弯曲转角变形，达到抑制施工桥塔在风等动荷载作用下的振动或减小振幅的效果，保证施工桥塔的安全性和可施工性等优点。
