Description

technical field

[0001] The invention relates to a support rod, in particular to a support rod for manufacture, trial assembly and adjustment of an arc gate of a hydropower station. Background technique

[0002] At present, due to the large size of the arc-shaped gates of hydropower stations, restricted by road transportation conditions, the gates are manufactured in multiple sections before leaving the factory, and then assembled and welded into a whole at the installation site after transported to the power station site. In the manufacturing process of the curved gate before leaving the factory, its manufacturing and pre-assembly process is an indispensable process in order to use the gate to meet the overall performance and design requirements, so as to ensure the smooth assembly of each section of the gate when the gate is installed on site. The pre-assembly of curved gates generally adopts the vertical assembly method of door leaves. Due to the large size of the gate and...
