The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Example 1:

referring to fig. 1-2, a track fixing device includes a cement pillow 1, fixing bolts 2 are symmetrically installed on the cement pillow 1, the fixing bolts 2 are connected with fixing blocks 3, wedge blocks 6 are fixedly connected to the inner sides of the fixing blocks 3, the fixing blocks 3 are fixedly installed through the fixing bolts 2 and fixing nuts 5, rails 7 are installed between the fixing blocks 3, first sliders 8 are arranged at the bottoms of the rails 7, first springs 9 are arranged under the first sliders 8, the first sliders 8 are installed in contact with second sliders 10, and the second sliders 10 are installed in contact with the inner sides of the fixing blocks 3 through second springs 11.

Specifically, the fixing block 3 is effectively and fixedly mounted through the fixing bolt 2, the washer 4 and the fixing nut 5.

More specifically, the rail 7 is fixedly installed through the wedge block 6 connected to the fixing block 3, the first sliding block 8, the second sliding block 10, the first spring 9 and the second spring 11 are matched to achieve floating installation of the rail 7, the problem of deformation compensation of the rail 7 caused by environmental differences is solved, pressure of the rail 7 on the fixing bolt 2 is greatly reduced, and accordingly the probability that the fixing bolt 2 becomes loose is greatly reduced.

Further, the wedge block 6 is inclined at the same angle as the rail 7.

Specifically, the inclined angle of the wedge block 6 is the same as that of the rail 7, so that the rail 7 can be clamped better, and the rail 7 can be conveniently returned after a train passes through.

Further, the distance between the lower bottom surface of the rail 7 and the second slider 10 is two millimeters.

Specifically, in order to avoid a large influence on the running difference of the train, the distance of two millimeters can ensure the deformation compensation caused by the environmental difference.
