[0031] The start-up of the drive motor three 24 will drive the screw rod three 25 to rotate. Since the screw rod three 25 is threadedly connected to the column 26, and the column 26 and the outer vertical tube 22 are slidingly arranged, the rotation of the screw rod three 25 will drive the column 26 to move vertically in the outer vertical tube 22, so that the height of the support leg 2 can be adjusted, and then the height of the ballastless track 100 is also adjusted.

[0032] Reference Figure 6 As shown, a sliding member 8 is provided between the outer vertical tube 22 and the column 26. The sliding member 8 includes a vertical frame 81 fixed on the inner wall of the outer vertical tube 22, and a rotating roller 82 rotatably provided in the vertical frame 81. The rotating axis of the rotating roller 82 is perpendicular to the vertical direction of the column 26. A plurality of rotating rollers 82 are provided and evenly distributed along the vertical direction of the column 26. The rotating rollers 82 are fitted between the inner wall of the outer vertical tube 22 and the outer wall of the column 26.

The arc plate 91 is located between the outer wall of the outer riser 22 and the inner wall of the rectangular sleeve 21. The arc plate 91 is fixed to the outer wall of the outer riser 22. The arc plate 91 is vertically arranged. The arc surface of the arc plate 91 is away from the side of the cross beam 11. The arc surface of the arc plate 91 is provided with teeth 911; the gear 92 is rotatably arranged on the inner wall of the rectangular sleeve 21, and the gear 92 is meshed with the teeth 911 on the arc plate 91; the mounting cover 93 is mounted on the outer wall of the rectangular sleeve 21; the worm 94 is rotatably arranged in the mounting cover 93; the worm wheel 95 is rotatably arranged in the mounting cover 93, the worm wheel 95 is meshed with the worm 94, and the worm wheel 95 is coaxially connected with the gear 92; the rotating rod 96 is mounted on the mounting cover 93, one end of the rotating rod 96 is coaxially connected to the end of one end of the worm 94, and the other end extends out of the mounting cover 93.

[0034] Since some track sections need to be set at an angle, the ballastless track 100 needs to be in an inclined state. At this time, the rotating rod 96 can be rotated to drive the rotation of the worm 94, and the rotation of the worm 94 will drive the rotation of the worm wheel 95. The rotation of the worm wheel 95 will drive the rotation of the gear 92. The rotation of the gear 92 will cause the angle of the arc plate 91 to change, which can cause the angle of the support leg 2 to change.

[0035] This application can explain its functional principle through the following operation methods:

[0036] After the gantry crane lifts the ballastless track onto the track base plate 200 on the track line, the position of the ballastless track 100 needs to be fine-tuned. At this time, the frame 1 can be placed above the ballastless track 100, and the support legs 2 at the four corners of the frame 1 can be fixedly installed on the side walls of the track base plate 200.

[0037] When the ballastless track 100 needs to be moved and adjusted along the direction of the cross beam 11, the driving motor 62 is started to drive the transmission shaft 63 on both sides to rotate, the transmission shaft 63 drives the screw 61 to rotate, and the screw 61 drives the nut seat 4 to move. Since the sliding direction of the nut seat 4 is consistent with the sliding direction of the cross beam 11, the ballastless track 100 can be moved and adjusted along the direction of the cross beam 11.

[0038] When the ballastless track 100 needs to be moved and adjusted along the track line direction, the driving motor 2 75 is started, driving the transmission shaft 2 76 on both sides to rotate, the transmission shaft 2 76 drives the worm 1 72 to rotate, the worm 1 72 drives the worm wheel 1 73 to rotate, the worm wheel 1 73 drives the screw rod 2 74 in the slide groove member 5 to rotate, the screw rod 2 74 will drive the slider 51 to move in the slide groove member 5, and the moving direction of the slider 51 is consistent with the direction of the track line, so that the ballastless track 100 can be moved and adjusted along the track line direction.

[0039] When the height direction of the ballastless track 100 needs to be adjusted, the start-up of the drive motor three 24 will drive the screw rod three 25 to rotate. Since the screw rod three 25 is threadedly connected to the column 26, and the column 26 is slidingly arranged with the outer vertical tube 22, the rotation of the screw rod three 25 will drive the column 26 to move vertically in the outer vertical tube 22, so that the height of the support leg 2 can be adjusted, and then the height of the ballastless track 100 is also adjusted.

[0040] Therefore, the technical problems in the prior art of rough structure of fine-tuning claws for track fine-tuning, large gaps, and low construction efficiency of ballastless track fine-tuning are solved, and the fine-tuning time is compressed, which increases the construction time for subsequent construction and improves the construction efficiency.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
