Ballastless track sleeper and ballast bed convenient to adjust
The invention relates to a ballastless track sleeper and ballast bed convenient to adjust, which is used for greatly reducing and adjusting the position of a steel rail, creating conditions for sleeper milling and grinding operation and ensuring the structural safety and durability. The ballastless track sleeper and ballast bed convenient to adjust comprises sleepers which are longitudinally arranged on a ballast bed at intervals and protrude out of the upper surface of the ballast bed, wherein each row of sleepers is composed of two sleeper blocks which are transversely arranged at intervalsand connected into a whole through a connecting device; a body of the sleeper block is provided with a steel rail mounting groove and blocking shoulders on the two transverse sides, the surface of thesteel rail mounting groove is higher than the upper surface of the ballast bed, the surface, which moves downwards in the plumb bob direction by the milling depth and intersects with the blocking shoulders on the two sides, of the steel rail mounting groove is taken as a preset sleeper milling surface, and a to-be-milled area of the sleeper is reserved between the surface of the steel rail mounting groove and the sleeper milling surface; and the ballast bed is provided with a longitudinally-through square groove below the steel rail mounting groove, an inner cavity of the square groove is filled with a filler, the width of the square groove is not less than that of the to-be-milled area of the sleeper, and the bottom surface of the square groove is lower than a milling surface of the sleeper.
一种利于调整的无砟轨道轨枕与道床，以实现对钢轨位置进行较大幅度降低调整，为轨枕铣磨作业创造条件，确保结构安全与耐久性。包括纵向间隔设置于道床上并凸出其上表面的轨枕，各排轨枕由横向间隔设置且由连接装置连接为一体的两个轨枕块构成。轨枕块的本体具有钢轨安装槽和横向两侧的挡肩，钢轨安装槽表面高于道床上表面，以钢轨安装槽表面沿铅锤方向下移铣磨深度并与挡两侧挡肩相交的面为预定的轨枕铣磨面，在钢轨安装槽表面与轨枕铣磨面之间预留的轨枕待磨区；道床在钢轨安装槽下方设置纵向贯通的方形凹槽，方形凹槽内腔由填充物填充，方形凹槽的宽度不小于轨枕待磨区的宽度，方形凹槽底面低于轨枕铣磨面。
