用于动臂塔机的避雷系统及动臂塔机
摘要：
本发明涉及一种用于动臂塔机的避雷系统及动臂塔机。该避雷系统包括避雷系统安装架、避雷针支承座和避雷针组件，所述避雷针支承座具有枢转中心和分别位于所述枢转中心两边的上段和下段，所述避雷针支承座通过所述枢转中心在竖直平面内可旋转地连接至所述避雷系统安装架，所述避雷针组件设置在所述上段的端部，所述避雷针组件和所述避雷针支承座的整体重心位于所述下段，使得所述避雷针组件始终沿竖直方向向上延伸。根据该方案，避雷针支承座在竖直平面内可旋转地连接至避雷系统安装架，且避雷针支承座和避雷针组件的整体重心位于避雷针支承座的下段，无论吊臂的工作位置如何变化，都能够保证避雷组件始终沿竖直方向向上延伸。
摘要（英）：

The invention relates to a cantilever tower crane and a lightning protection system for the same. The lightning protection system comprises a lightning protection system mounting frame, a lightning rod supporting seat and a lightning rod component, the lightning rod supporting seat has a pivoting center, an upper section and a lower section, the upper section and the lower section are positioned on two sides of the pivoting center respectively, the lightning rod supporting seat is rotatably connected to the lightning protection system mounting frame through the pivoting center in a vertical plane, the lightning rod component is arranged on the end portion of the upper section, the overall center of gravity of the lightning rod component and the lightning rod supporting seat is positioned in the lower section, and the lightning rod component is enabled to constantly extend upwards along the vertical direction. According to the scheme, the lightning rod supporting seat is rotatably connected to the lightning protection system mounting frame in the vertical plane, and the overall center of gravity of the lightning rod component and the lightning rod supporting seat is positioned in the lower section, so that no matter how working position of a lifting arm is changed, the lightning rod component can be ensured to constantly extend upwards along the vertical direction.
