Problems solved by technology

Due to the special working stroke of the boom of the jib tower crane, the height of the tip of the arm far exceeds the height of the top of the A-frame when it is in a large range of work, and its position is constantly changing when it is working. The traditional fixed-installed lightning rod assembly cannot Adapting to this position change cannot meet the lightning protection requirements of the luffing jib tower crane and its boom

Abstract

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.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a lightning protection system for a boom tower crane and the boom tower crane. Background technique [0002] At present, the luffing jib tower crane has a large number of applications in densely built sites such as Southeast Asian countries due to its excellent space deployment capabilities. However, the weather conditions of frequent thunderstorms require that the luffing jib tower crane must have excellent lightning protection technical measures. Due to the special working stroke of the boom of the jib tower crane, the height of the tip of the arm far exceeds the height of the top of the A-frame when it is in a large range of work, and its position is constantly changing when it is working. The traditional fixed-installed lightning rod assembly cannot Adapting to this position change cannot meet the lightning protection requirements of the jib tower crane and its boom. The...
