[0027] Furthermore, the support shell 3-1-1 of the two moving wheel groups 3-1 located at the front side of the support frame 1 in the direction of travel is rotatably connected to the bottom of the side frame 1-1, and the two support shells 3-1-1 are provided with a steering mechanism 3-3 for driving the support shell 3-1-1 to rotate relative to the side frame 1-1, so as to realize the steering of the two moving wheel groups 3-1 at the front side, thereby correcting the movement of the paving trolley of the present invention along the direction of the railway track; specifically, as Figure 3As shown, the steering mechanism 3-3 is a first telescopic oil cylinder, both ends of which are hinged on the bottom of the side frame 1-1 and the supporting shell 3-1-1 respectively. A first solenoid valve is arranged on the oil pipeline of the first telescopic oil cylinder, and the first solenoid valve is electrically connected to the control module. When working, the switch of the first solenoid valve is controlled by the control module, thereby controlling the extension and retraction of the first telescopic oil cylinder, thereby adjusting the direction of the moving wheel group 3-1.

[0028] Further, if Figure 6 As shown, the crossbeam 1-2 is provided with a slide rail 5-1 parallel to the crossbeam 1-2, and the bottom of the top bracket 2-1 is provided with a slider 5-2 matching the slide rail 5-1, and the top bracket 2-1 is slidably connected to the crossbeam 1-2 through the slider 5-2 cooperating with the slide rail 5-1; Fig.12 As shown, a rack 5-3 parallel to the slide rail 5-1 is arranged on the crossbeam 1-2, and a second servo motor 5-4 is arranged at the bottom of the top bracket 2-1.

When the two claw clamps rotate toward each other, their vertical parts 2-4-1 are clamped on both sides of the track plate respectively, and their horizontal parts 2-4-2 are inserted under the track plate. The two groups of claw clamps 2-4 are respectively located on the front and rear sides of the top bracket 2-1, so as to clamp and grasp the track plate. Conversely, when the two claw clamps 2-4 in a group are rotated away from each other, the track plate can be loosened; and a connecting rod 2-5 is connected between the two mounting seats 2-3-1 connected to the two claw clamps 2-4 in a group, and the mounting seats 2-3-1 of the two claw clamps 2-4 are connected as a whole.
