The invention discloses an internally-engaged anti-falling cantilever structure for a railway contact network, which comprises a cantilever support column, a cantilever support, a flat cantilever, an inclined cantilever, a positioning pipe support, a positioning pipe and a positioner, one end of the flat cantilever and one end of the inclined cantilever are both connected with the cantilever support column, the flat cantilever is horizontally connected to the upper side of the cantilever support column, and the inclined cantilever is horizontally connected to the lower side of the cantilever support column; the inclined cantilever is obliquely arranged on the lower side of the flat cantilever, the end, away from the cantilever supporting column, of the inclined cantilever is connected with the flat cantilever through a butterfly-shaped fixing support, the cantilever support is obliquely arranged between the flat cantilever and the inclined cantilever, the upper end of the cantilever support is connected with the flat cantilever through a first connector, and the lower end of the cantilever support is connected with the inclined cantilever through a supporting device. According to the internally-engaged anti-falling cantilever structure for the railway contact network, the use of screws is reduced, the problem that in the prior art, due to the fact that the number of fixing bolts is large, faults of the contact network occur frequently is solved, the stability of cantilever supporting and connecting is improved, and then the overall safety of the railway contact network is improved.

    本发明公开了一种内咬合式防脱型铁路接触网用腕臂结构,包括腕臂支柱、腕臂支撑、平腕臂、斜腕臂、定位管支撑、定位管和定位器,平腕臂和斜腕臂的一端均与腕臂支柱连接,平腕臂水平连接在腕臂支柱的上侧,斜腕臂倾斜设置在平腕臂的下侧,斜腕臂远离腕臂支柱的一端通过蝶形固定支座与平腕臂连接,腕臂支撑倾斜设置在平腕臂与斜腕臂之间,腕臂支撑的上端通过连接器一与平腕臂连接,腕臂支撑的下端通过支撑器与斜腕臂连接。本发明采用上述结构的一种内咬合式防脱型铁路接触网用腕臂结构,减少了螺钉的使用,减少了现有技术中因固定螺栓较多而导致接触网故障频发的问题,提高了腕臂支撑连接的稳定性,进而提高了铁路接触网整体的安全性。
