The invention belongs to the technical field of subway power supply contact network construction, and particularly relates to a rigid contact network expansion joint mounting and adjusting method. Comprising the following steps: S100, reserving an expansion joint mounting space; s200, a reserved contact line end of the busbar is polished, a contact line with the length being 300 mm larger than that of an expansion joint sliding way needs to be reserved at the ends, connected with the two ends of the expansion joint, of the busbar, meanwhile, the reserved contact line is straightened, hard folding points do not appear, and before the expansion joint is installed, the reserved contact line is cut off till the length of the expansion joint sliding way is +/-5 mm; the contact end part is polished into an oblique angle; s300, an expansion joint is installed; and S400, a contact line is installed and clamped. According to the invention, the expansion joint is used at the joint of the anchor section of the rigid suspension contact net system to compensate the longitudinal expansion amount or contraction amount of the busbar in the anchor section due to temperature change, so that the electrical splicing between the anchor sections and the smooth transition of the pantograph between the anchor sections are realized.
本发明属于地铁供电接触网施工技术领域,具体涉及一种刚性接触网膨胀接头安装调整方法。包括以下步骤,S100:预留膨胀接头安装空间;S200:打磨汇流排预留接触线端头,与膨胀接头两端连接的汇流排端部必须预留膨胀接头滑道长度+300mm的接触线,同时对预留接触线进行校直,不得出现硬折点,在安装膨胀接头前,将预留接触线长度切断至膨胀接头滑道长度±5mm,并将接触端部打磨成斜角;S300:安装膨胀接头;S400:装卡接触线。本发明通过将膨胀接头用于刚性悬挂接触网系统锚段关节处,补偿锚段内汇流排因温度变化而产生的纵向膨胀量或收缩量,实现了锚段间的电气续接及受电弓在锚段间的平滑过渡。
