【正文】 蘭州交通大學畢業(yè)設(shè)計（論文） I 摘 要 隨著社會和經(jīng)濟技術(shù)的發(fā)展，電氣化鐵路的發(fā)展也越來越迅速。我國對能夠適用于電氣化鐵路的接觸網(wǎng)也提出了相關(guān)的要求。本設(shè)計的目的是完成嘉峪關(guān)車站接觸網(wǎng)平面設(shè)計，同時按要求繪制接觸網(wǎng)設(shè)備裝配圖和平面圖。 首先對設(shè)計地區(qū)的氣象條件資料進行收集，根據(jù)鐵路目標速度對線索材料進行了選擇，再確定其懸掛類型。根據(jù)氣象條件及線索材料計算負載。其次，根據(jù)最大受風偏移計算得到最大跨距；根據(jù)規(guī)程規(guī)定的錨段長度選擇錨段，使其張力差要滿足要求。然后，對硬橫跨進行分析選擇。 考慮到接觸網(wǎng)將來可能的改進及預留，根據(jù)計算結(jié)果對接觸網(wǎng)進行了 相應(yīng)的調(diào)整，以使本設(shè)計滿足電氣化鐵路的技術(shù)要求。 最后在上述原理的基礎(chǔ)上，對嘉峪關(guān)車站接觸網(wǎng)進行 CAD 平面設(shè)計，并對具有代表性的支柱進行了容量的校驗計算。在接觸網(wǎng)平面圖的表格欄里對地質(zhì)情況、支柱類型、安裝圖號、側(cè)面限界等進行相應(yīng)的說明。 本論文以接觸網(wǎng)的基本技術(shù)原理為核心，以實際線路狀況為依據(jù)，對嘉峪關(guān)車站的接觸網(wǎng)布置進行了平面設(shè)計，基本滿足電氣化鐵路的技術(shù)要求 。 關(guān)鍵詞：接觸網(wǎng)；平面設(shè)計；車站 蘭州交通大學畢業(yè)設(shè)計（論文） II Abstract With the development of social and economical technology, the electrified railway is developing more and more rapidly. Our country also makes a related request for catenary of electrified railway. This design is intended to plete graphic design of catenary for Jiayuguan station, and to draw its device assembly drawing and graphic draft. Firstly, the suspension was selected after the Jiayuguan weather condition information was collected and clue material was sift. The load was calculated according to weather condition and clue material. Secondly, the maximum outreach is obtained from the wind shift. Anchoring section is chosen according to specified anchoring section to satisfy tension difference. Then, portal structure was thesis considering the improvement and reserve in the future of catenary carries out some corresponding adjustments for the design of catenary according to the result of calculation, so that the design could be contented with the technical requirements of the electrified railway. Finally, on the basis of the above principle, this thesis concentrated on the graphic design of Jiayuguan station with CAD, also conducted check putation for typical capacity of the pillars. Graphic design of catenary in the form column on the pillar type, geology, side gauge, install the corresponding figure number and other instructions. Based on the basic technical principle of catenary and according to the actual railway condition, this thesis pleted graphic design of catenary for Jiayuguan station, which could met the basic technological demand of electrified railway.
