本发明提供铁轨铺设施工系统，涉及铁轨铺设领域，包括：安装结构；所述安装结构通过螺栓固定在固定架部件的底部边角位置，插板结构的内端为楔形结构，插板结构的内部开设有T形结构的滑槽，滑槽的内部插入有可自由抽拉滑动的固定板。控制轨枕处于推动块与辅助板之间，推动杆在倾斜槽内部滑动，控制推动块横向位移，推动轨枕向侧边移动，轨枕与触发结构接触，触发结构通过齿槽二控制旋转齿轮旋转，然后通过齿槽控制固定板向内移动，插入到轨枕的底部，固定板移动之后，加大与轨枕的接触面积，提高对轨枕的固定效果，提高稳定性，消除安全隐患，解决了在使用铺设机械控制轨枕摆放的时候，移动的过程中，存在滑动的风险，存在安全隐患的问题。

The invention provides a rail laying construction system, and relates to the field of rail laying. The mounting structures are fixed to the corners of the bottom of the fixing frame component through bolts, the inner ends of the inserting plate structures are of wedge-shaped structures, sliding grooves of T-shaped structures are formed in the inserting plate structures, and fixing plates which can be freely pulled and slide are inserted into the sliding grooves. A sleeper is controlled to be located between a pushing block and an auxiliary plate, a pushing rod slides in an inclined groove, the pushing block is controlled to move transversely, the sleeper is pushed to move towards the side edge, the sleeper makes contact with a triggering structure, the triggering structure controls a rotating gear to rotate through a second tooth groove, and then a fixing plate is controlled through the tooth groove to move inwards and be inserted into the bottom of the sleeper. After the fixing plate moves, the contact area between the fixing plate and the sleeper is enlarged, the fixing effect on the sleeper is improved, the stability is improved, potential safety hazards are eliminated, and the problems that sliding risks exist and potential safety hazards exist in the moving process when laying machinery is used for controlling the sleeper to be placed are solved.
