Rail for improving smoothness by adopting main and auxiliary steel rails and up-and-down lap joint type joints
The utility model discloses a rail for improving smoothness by adopting main and auxiliary steel rails and up-down lap joints. According to the main-auxiliary type steel rail, a main rail comprises an I-shaped rail and a T-shaped rail, auxiliary rails are special-shaped channel steel shaped like the Chinese character "ye", a wide bottom plate of the Chinese character "ye" serves as an anti-creeper, and rail bodies of the main rail are exactly nested by notches of the corresponding auxiliary rails in a complementary mode; and then fastening is carried out to form the main and auxiliary steel rail with high cost performance. a piece of the lower portion of the wheel feeding end of the main rail is cut off, so that a head waist protrusion is formed on the rail head and part of the rail waist, similarly, a piece of the upper portion of the wheel facing end of the main rail is cut off, so that a bottom waist protrusion is formed on the rail bottom and part of the rail waist, and the bottom waist protrusion and the head waist protrusion are complementary and are in lap joint to form a complete main rail section to form convex-convex lap joint. When a wheel is pressed on the wheel feeding end, the head waist protrusion presses the bottom waist protrusion, so that the wheel facing end and the wheel feeding end sink synchronously, the rail surfaces of the wheel facing end and the wheel feeding end are kept horizontal and consistent, steps are avoided, and joint problems can be comprehensively eliminated on the basis.
一种采用主辅式钢轨及上下搭接式接头提高平顺性的轨道。主辅式钢轨：主轨包括工字轨和T字轨，辅轨是一种业字形异形槽钢，业字的宽底板充当防爬器，主轨的轨身都被所对应辅轨的槽口刚好互补的嵌套住；然后进行紧固，构成高性价比的主辅式钢轨。凸凸式搭接：主轨送轮端的下部被切掉一块，使其轨头加部分轨腰形成一个头腰凸，同样，主轨迎轮端的上部被切掉一块，使其轨底加部分轨腰形成一个底腰凸，底腰凸与头腰凸互补，两者搭接后构成完整的主轨截面，形成凸凸式搭接，当车轮压在送轮端上时，头腰凸就压住了底腰凸，使迎轮端与送轮端同步下沉，使两者的轨面保持水平一致，避免台阶的产生，在此基础上可全面消除接头病害。
