一种±800kV特高压直流线路靴板连接结构
摘要：
本实用新型提供了一种±800kV特高压直流线路靴板连接结构，包括塔脚底板、第一靴板、第二靴板、第三靴板和加劲板；其中，第一靴板、第二靴板和第三靴板焊接在塔脚底板上，且第二靴板和第三靴板焊接在第一靴板的两侧，第二靴板和第三靴板在同一平面上垂直于第一靴板，第二靴板和第三靴板与塔脚底板的夹角与第一靴板与塔脚底板的夹角相等，第一靴板、第二靴板和第三靴板上分别设置有加劲板。本实用新型一种±800kV特高压直流线路靴板连接结构采用塔腿主材与靴板通过螺栓连接的型式，替代了现有技术中塔腿主材与塔脚底板直接焊接的型式，该靴板连接型式简化了塔脚构造，减小了其加工难度，降低了塔重，进而有利于输电线路铁塔的运输和安装。
摘要（英）：

The utility model provides a plus/minus 800 kV extra-high voltage direct-current transmission line shoe plate connecting structure. The structure comprises a tower foot bottom plate, a first shoe plate, a second shoe plate, a third shoe plate and stiffening plates, wherein the first shoe plate, the second shoe plate and the third shoe plate are welded to the tower foot bottom plate; the second shoe plate and the third shoe plate are welded to the two sides of the first shoe plate; the second shoe plate and the third shoe plate are perpendicular to the first shoe plate in the same plane; an included angle between each of the second shoe plate and the third shoe plate is equal to that between the first shoe plate and the tower foot bottom plate; the stiffening plates are respectively arranged on the first shoe plate, the second shoe plate and the third shoe plate. The plus/minus 800 kV extra-high voltage direct-current transmission line shoe plate connecting structure adopts a mode that the tower foot principal material is in bolted connection with the shoe plates to replace a mode that in the prior art the tower foot principal material is directly welded with the tower foot bottom plate. The shoe plate connection mode simplifies the tower foot construction, reduces the processing difficulty, lowers weight of a tower, and further is beneficial to transportation and installation of a transmission line tower.
