本发明属于船体装配分段定位技术领域,具体公开了一种吊线锤挡风装置。该吊线锤挡风装置包括:挡风箱、高度调节装置,以及多个移动轮;挡风箱具有由挡风布围成且在竖直方向延伸的悬吊通道;悬吊通道的上端开口上覆盖有顶板,悬吊通道的下端开口上覆盖有底板;顶板开设有第一通孔,底板开设有第二通孔。高度调节装置用于驱动顶板升降。线锤和棉线可依次穿过顶板的第一通孔、悬吊通道和第二通孔,以核对分段中心线与船台、场地堪划好的中心线是否在同一铅垂面内;顶板、底板、挡风布形成的挡风腔可有效地防止自然风吹向棉线和线锤,以减少自然风的影响,提高吊线锤测量方法的测量精度,保证船舶的安装精度达到造船的要求。

    The invention belongs to the technical field of ship body assembly section positioning, and particularly discloses a plumb bob wind shielding device. The plumb bob wind shielding device comprises a wind shielding box, a height adjusting device and a plurality of moving wheels. The wind shielding box is provided with a suspension channel which is defined by wind shielding cloth and extends in the vertical direction. A top plate covers an opening in the upper end of the suspension channel, and a bottom plate covers an opening in the lower end of the suspension channel. The top plate is provided with a first through hole, and the bottom plate is provided with a second through hole. The height adjusting device is used for driving the top plate to lift. A plumb bob and a cotton thread can sequentially penetrate through the first through hole of the top plate, the suspension channel and the second through hole so as to check whether the center line of the section and the marked center line of a slipway and the field are in the same vertical plane or not. A wind shielding cavity formed by the top plate, the bottom plate and the wind shielding cloth can effectively prevent natural wind from blowing to the cotton thread and the plumb bob, so that the influence of the natural wind is reduced, the measurement precision of the plumb bob measurement method is improved, and the installation precision of a ship is ensured to meet the shipbuilding requirement.
