Connecting device and ballastless rail
The embodiment of the invention provides a connecting device and a ballastless rail. The side, deviating from the partition plate, of the first elastic part and the side, deviating from the partitionplate, of the second elastic part abut against the connecting mechanism. When the rail plate of the ballastless rail is broken into a plurality of sub-rail plates and the connecting device is connected with two adjacent sub-rail plates, the temperature force of the sub-rail plates acts on the first elastic part or the second elastic part through the connecting mechanism and then is transmitted tothe partition plate through the first elastic part or the second elastic part. A first elastic part and a partition plate are arranged; or, the second elastic parts and the partition plates enable excessive temperature force and temperature deformation of the sub-rail plates to be released, so that vertical upward arching deformation of the rail plates of the ballastless rail at the weak positionwhere rail defects are concentrated is relieved, and the risk of vertical instability of the rail plates of the ballastless rail due to excessive vertical upward arching deformation is reduced.
本申请实施例提供一种连接装置和无砟轨道，由于第一弹性件背离隔板的一侧以及第二弹性件背离隔板的一侧均与连接机构抵接，当无砟轨道的轨道板打断成多个子轨道板且连接装置连接相邻两块子轨道板，子轨道板的温度力通过连接机构作用在第一弹性件或第二弹性件上，再经第一弹性件或第二弹性件传递到隔板。通过第一弹性件和隔板，或，第二弹性件和隔板，使子轨道板的过大的温度力和温度变形得以释放，以缓解无砟轨道的轨道板在轨道病害较为集中的薄弱位置的竖向上拱变形，降低无砟轨道的轨道板由于竖向上拱变形过大而出现竖向失稳的风险。
