[0019] Example: as shown in Figures 1 to 3 , the fixed support of the sleeper state monitoring device for high-speed railway in the utility model is used for installing the sensor 8 to the monitoring position of the high-speed railway sleeper, which is generally the middle position of the sleeper.

[0020] Specifically, the main body of the fixing support includes an upper clamping plate 1, a lower clamping plate 2 and a hinge cover plate 7. The upper clamping plate 1 is installed above the position of the sleeper in use, and the lower clamping plate 2 is installed below the position of the sleeper in use, i.e. from below the sleeper. The upper clamping plate 1 and one side of the lower clamping plate 2 are fixedly connected through a first fastening bolt 3 and a third fastening bolt 5. The upper clamping plate 1 and the other side of the lower clamping plate 2 are fixedly connected through a second fastening bolt 4 and a fourth fastening bolt 6. In this embodiment, the second fastening bolt 4 and the fourth fastening bolt 6 are both side wing fastening bolts, which are used to be connected with the hinge cover plate 7. The hinge cover plate 7 is matched with the shape of different sensors, and is limited in three directions of up and down, front and back, and left and right, and makes the sensor 8 closely fit the outer vertical surface of the sleeper.
