[0023] The technical solution in this embodiment will be clearly and completely described below in conjunction with the accompanying drawings. The described embodiments are only some of the embodiments, not all of them. Based on the embodiments in this solution, all other embodiments obtained by ordinary technicians in this field without making creative work are within the protection scope of this solution.

[0024] Example 1

[0025] like Figures 1 to 5 As shown, this embodiment designs a centerline adjustment mechanism for ballastless track adjustment, including a centerline adjustment motor 1, a docking shell 3, an adjustment screw rod 4, an adjustment sleeve 6 and other components.

[0026] A fixed pipe rod 8 is vertically connected to the rail 9 of the ballastless track; the fixed pipe rod 8 is a square pipe structure, and the side of the adjustment sleeve 6 can abut against the pipe wall of the fixed pipe rod 8 and limit the rotation of the adjustment sleeve 6.

[0027] An adjusting piece 7 is fixedly arranged in the tube cavity at the end of the fixed tube rod 8, and the adjusting piece 7 is fixed by a screw that passes through the side wall of the fixed tube rod 8 and is nailed into the edge of the adjusting piece 7. A circular hole is arranged in the middle of the adjusting piece 7, and the adjusting sleeve 6 is T-shaped, and a part of the adjusting sleeve 6 can be inserted into the circular hole.

[0028] A guiding docking cavity 5 is provided inside the docking shell 3 . The guiding docking cavity 5 is a square cavity structure. The guiding docking cavity 5 is used for inserting the end of the fixed pipe rod 8 .

[0029] The guide docking cavity 5 is provided with an adjustment screw 4, which is in transmission connection with the centerline adjustment motor 1; when the centerline adjustment motor 1 is started, the adjustment screw 4 can rotate under the drive of the motor 1. The adjustment sleeve 6 is threadedly matched with the adjustment screw 4.

[0030] A gear transmission mechanism 2 is disposed on the side wall of the docking shell 3 , the output end of the gear transmission mechanism 2 is fixedly connected to the adjustment screw 4 , and the input end of the gear transmission mechanism 2 is fixedly connected to the centerline adjustment motor 1 .

[0031] A plurality of fixed pipe rods 8 are fixed in the length direction of the rail 9, and a centerline adjustment mechanism is correspondingly provided at the end of each fixed pipe rod. All the centerline adjustment mechanisms can control the fixed pipe rods 8 to move in the same transverse direction.

[0032] The upper portion of the docking shell 3 has a connecting portion for external connection, so as to facilitate the connection of the centerline adjustment mechanism to other components.

[0033] When the centerline adjustment mechanism is in use, the docking shell 3 is first fixed relative to the ground, and the end of the fixed pipe rod 8 is inserted into the guide docking cavity 5, so that the adjustment sleeve 6 extends into the tube cavity of the fixed pipe rod 8 to be inserted into the circular hole of the adjustment plate 7, and at the same time, one end of the adjustment sleeve 6 is abutted against the end face of the adjustment plate 7, and the side of the adjustment sleeve 6 is abutted against the side wall of the tube cavity of the fixed pipe rod 8. When the adjustment screw 4 is driven by the centerline adjustment motor 1 to rotate, the adjustment sleeve 6 can slide laterally relative to the adjustment screw 4, and push the fixed pipe rod 8 to move laterally through the adjustment plate 7, thereby adjusting the lateral position of the centerline of the ballastless track. When the installation position of the centerline adjustment mechanism is turned to the other end of the fixed pipe rod 8, the lateral position of the centerline of the ballastless track will be adjusted in the opposite direction.

[0034] The above embodiments are merely examples for the purpose of clarifying the description, and are not intended to limit the implementation methods; it is not necessary and impossible to list all implementation methods exhaustively. However, obvious changes or modifications derived therefrom are still within the scope of protection of the present technology.
