[0038] Preferably, the number of traveling wheels 15 is 4. The through-hole connecting piece 16 and the mobile base 11 are integrally formed. The vertical lifting platform 14 is provided with a rail groove for clamping a steel rail, and the fixed end 25 is provided with a rail groove for clamping a steel rail.

[0039] The track gauge fine adjustment device of the ballastless high-speed railway line is composed of a mobile adjustment mechanism 1 and a fixed mechanism 2. The mobile adjustment mechanism 1 comprises a mobile base 11, four walking wheels 15, a hydraulic elevator 12 and a vertical lifting platform 14. The fixed mechanism 2 comprises a fixed end 25, a bidirectional gauge adjusting nut 23, a bidirectional ratchet wrench 22, a fixed end connecting rod 24 and a mobile end connecting rod 21. The mobile adjustment mechanism 1 and the fixed mechanism 2 are connected by a pin shaft 13 to form a set of high-speed railway track gauge fine adjustment device.

[0040] The principle of the track gauge fine adjustment device of the ballastless high-speed railway line is that the fixed end 25 is installed on the fixed rail which does not need to be adjusted or has been adjusted, the mobile adjustment mechanism 1 is placed under the rail which needs to be adjusted, the two devices are connected by the pin shaft 13, the hydraulic elevator 12 is started to drive the vertical lifting platform 14 to lift the rail, at this time, the walking wheels 15 are in contact with the ballastless track bed, the ballastless track bed is used as the bearing base to bear the weight of the lifted rail, when the rail needs to be adjusted in the transverse direction, the walking wheels 15 can move on the flat ballastless track bed to reduce the transverse resistance, the bidirectional ratchet wrench 22 is turned to drive the bidirectional gauge adjusting nut 23, the bidirectional gauge adjusting nut 23 is internally processed with one end of the positive internal thread and one end of the reverse internal thread, which cooperates with the positive and reverse external threads on the fixed end connecting rod 24 and the mobile end connecting rod 21.

[0041] The specific operation method is: the separated track gauge fine adjustment device of the high-speed rail line is moved to the high-speed rail line to be adjusted, the fixed end 25 is lifted, the fixed end 25 is installed on the steel rail which does not need to be adjusted or has been adjusted, and then the steel rail which needs to be adjusted is placed under the mobile adjustment mechanism 1, the pin shaft 13 is penetrated to connect the two devices. The fittings on the side of the steel rail which needs to be adjusted are loosened, if the fine adjustment fastener needs to be replaced, the original fastener is removed, the track gauge is adjusted, and then the corresponding fine adjustment fastener is placed. The hydraulic lift 12 is started, the vertical lifting platform 14 is driven to lift the steel rail, and the lifting height of the steel rail is the height of the track under the pad. At this time, the rail groove on the vertical lifting platform 14 has clamped the two sides of the bottom of the moving steel rail, the steel rail can be adjusted in the horizontal direction and the vertical height, the existing steel rail distance is observed according to the track gauge, the direction fork on the bidirectional ratchet wrench 22 is adjusted according to the standard track gauge requirement or the line requirement, the bidirectional ratchet wrench 22 is pulled and the bidirectional gauge adjusting nut 23 is driven, the forward and reverse internal threads in the bidirectional adjusting nut 23 are matched with the forward and reverse external threads on the fixed end connecting rod 24 and the moving end connecting rod 21, and the distance between the two steel rails is finely adjusted. When the line track gauge is adjusted, the pressure relief valve on the hydraulic lift is opened, the vertical lifting platform and the hydraulic lift are lowered to the initial state, the pin shaft 13 is pulled out, the fixed end 25 is removed, the moving end is moved out from under the steel rail, and the fine adjustment operation of the line track gauge is completed.
