研究目的: 从架空接触网的各种悬挂分析入手,根据轨行区的净空高度设计值( H) ,提出适合车辆段带上盖条件下的接触网设计方案,这种方案融合常规接触网的各种单一设计标准,不仅在系统上满足安全可靠性、技术合理性的要求,而且功能适用性强、美观性好,并且因优化资源配置而使经济投资更加合理,这种新的模式可以为类似工程设计提供参考借鉴。
研究结论: H≤6. 5 m,采用刚性悬挂; 6. 5 m < H≤8 m,采用地面立杆与顶板悬挂相结合的方式; H >8 m,采用地面立杆腕臂柱悬挂。
Research purposes: Beginning with the analyses of all kinds of suspension mode of catenary and according to the design value( h) of the head room of the track section,the design scheme of the catenary suspension in the subway car depot with cover is offered. This scheme mixes all kinds of the single design standard of conventional catenary together. This scheme not only can meet the requirements of reliability in safety and rationality in technology,but also it has features of the good usability in function,good looking and the more rationality in financial investment because of the optimization of the distribution of resources. This mode can provide the reference to the similar works.
Research conclusions: When the design value H of the head room of the track section is equal to or less than 6. 5 m,the rigid suspension mode of the catenary should be adopted. When the design value is more than 6. 5 m and equal to or less than 8 m,the suspension mode of using ground column should be used along with the ceiling suspension. When the design value is more than 8 m,the suspension mode of the ground column and twist - arm post should be adopted.
