高架站半高站台门驱动支承方式对比分析

地铁高架站台采用的是半高站台门,与地下站全高站台门由站台顶层横梁及站台板分散承重的方式不同,半高站台门承重方式主要为站台板。半高站台门门扇无法悬挂于门机梁上,直接通过门体驱动结构承压于站台板上,目前行业内主要驱动结构方式为滑轮组支承或直线导轨,文章对广州地铁各线路半高站台门驱动结构方式进行对比分析,给后续线路建设提供参考。

The half height platform door is adopted in the elevated platform of subway,which is different from the way that the full height platform door of underground station is loaded by the top beam and platform plate of the platform,and the load-bearing mode of the half height platform door is mainly the platform plate.The half height platform door can not be suspended on the gantry crane beam,and it is directly pressed on the platform plate through the door driving structure.At present,the main driving structure mode in the industry is pulley block support or linear guide.This paper compares and analyzes the driving structure of half height platform door in Guangzhou Metro Lines,and provides reference for subsequent metro line construction.
