[0002] Ballastless track is a track that uses concrete, asphalt and other integral foundations to replace the granular gravel roadbed. The track itself is made of concrete, and the roadbed does not need gravel. The rails and sleepers are laid directly on the concrete roadbed. Compared with ballasted track, ballastless track avoids ballast splashing, has good smoothness and stability. At the same time, ballastless track has been widely used by domestic and foreign railways due to its high stability, less maintenance, and long life. High-speed rail prefers this type of track. At present, the laying method of ballastless track is basically rough laying first, then fine adjustment, and the whole process is adjusted many times. During the fine adjustment, the whole process needs to use a total station to measure the laying error, and then fine-tune it. This method is time-consuming and labor-intensive. At the same time, during the concrete pouring process, the ballastless track plate will float up and down and deviate left and right. The traditional method cannot achieve real-time monitoring of the position of the plate during the pouring process, and there is no way to adjust it at all times. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] like Figure 1 As shown in FIG. 3 , an offset adjustment device for ballastless track is mainly composed of a bracket 1, a fixing plate 4, an infrared detection component A and a fine adjustment component B. The two ends of the n-shaped bracket 1 are used to be set up on the left and right sides of the ballastless track plate C. The infrared detection component A is set at the center of the top surface of the bracket 1. At least two lower pressing plates 3 are installed on each bracket 1, and the lower end of the lower pressing plate 3 is against the ballastless track plate C. The fine adjustment component B is installed on the left and right legs of the bracket 1. Among them, the bracket 1 is fixed by clamping the ballastless track plate C from the left and right sides through a pair of fixing plates 4 set at the middle and lower parts of the two side legs.

[0025] The infrared detection assembly A is mainly composed of an infrared transmitter 14, an inclination display 8 and an infrared centering positioner 10. Figure 5-6 As shown, the infrared centering locator 10 is placed below the infrared transmitter 14, the infrared transmitter 14 is mounted on the top of the vertical mounting rod 2, the inclination display 8 is arranged on the left or right side of the vertical mounting rod 2, and the infrared transmitter 14 and the infrared centering locator 10 are both slidably mounted on the offset distance adjustment slide rail 13 above the bracket 1, and the infrared transmitter 14 is rotatably mounted on the vertical mounting rod 2 through the angle adjuster 12. The infrared centering locator 10 is centered by aligning the center line of the ballastless track slab on the ballastless track slab C.

[0026] like Figure 4 As shown, the fine adjustment assembly B is mainly composed of a vertical adjustment bolt 6, a horizontal adjustment bolt 7 and a moving frame 9. The outer end of the moving frame 9 is fixedly sleeved on the vertical adjustment bolt 6, and the inner end is provided with a supporting iron column 5 driven into the ballastless track plate C. The inner end of the moving frame 9 is sleeved on the support leg of the bracket 1, and the moving frame 9 can move up and down relative to the bracket 1, so that when the vertical adjustment bolt 6 is rotated, the ballastless track plate C is driven by the moving frame 9 to perform fine adjustment of the upper and lower positions.

[0027] A plurality of horizontal adjustment bolts 7 are provided through the legs on both sides of the bracket 1, and the horizontal adjustment bolts 7 are tightly pressed against the side of the ballastless track plate C. It is preferred that four horizontal adjustment bolts 7 are provided, two of which are provided on each of the legs on both sides of the bracket 1, and the two are respectively located on the front and rear sides of the legs. The movable frame 9 is provided with a through slot 9a extending up and down at the position corresponding to the horizontal adjustment bolt 7, and when the horizontal adjustment bolt 7 is rotated, the ballastless track plate C is finely adjusted in the left and right directions.

[0028] The steps for using the device are as follows:

[0029] Step 1: Place the ballastless track slab C to be roughly laid on the rough laying template, and install at least two plate-type ballastless track fine-adjusting devices at intervals on each ballastless track slab C. It is best to install two plate-type ballastless track fine-adjusting devices, which are respectively placed at the front and rear ends of the ballastless track slab C to be roughly laid. Drive the supporting iron column 5 into the ballastless track slab C, and at the same time, the plate-type ballastless track fine-adjusting device clamps and fixes the ballastless track slab C through the fixing plates 4 on both sides.

[0030] Step 2: Concrete is poured through the grouting holes on the ballastless track slab C, and during the pouring process, the deviation of the ballastless track slab C is detected by the infrared detection component A. According to the inclination display, the staff turns the horizontal adjustment bolt 7 to complete the coarse adjustment in the horizontal direction.

[0031] Step 3: Place at least two infrared receivers on the previous ballastless track slab C that has been fine-tuned. It is best to install two infrared receivers, one at the front and one at the back of the ballastless track slab C that has been fine-tuned. The infrared transmitter 14 installed on the ballastless track slab C to be adjusted emits an outer red line to the infrared receiver, and the staff rotates the vertical adjustment bolt to make the infrared transmitter 14 and the infrared receiving device on the same horizontal plane. Repeat this process so that each infrared transmitter 14 on the ballastless track slab C to be adjusted is on the same plane as the fine-tuned infrared receiver, thereby completing the fine-tuning of the upper and lower positions of the ballastless track slab C. At this time, the fine-tuning of the ballastless track slab C in the straight slope section and the straight flat slope section is completed, and the initial adjustment of the ballastless track in the curved section is completed.

[0032] Step 4: When fine-tuning the curved ballastless track, select the installed ballastless track plate C as the reference basis for fine-tuning, and calculate the adjustment angle and deviation displacement △X based on the ballastless track selected as the reference system. Figure 7 As shown, the known quantities are R and θ1, and the following formula is used to calculate the residual:

[0033]

[0034] Where: R is the radius of the ballastless track curve section, and θ1 is the angle corresponding to the curve section.

[0035]

[0036] Where: θ is the turning angle completed by the curve segment.

[0037] The number of ballastless track slabs C required for the curved section is:

[0038]

[0039] Where: [] is the upward rounding function, L is the length of the ballastless track curve section, and l is a single ballastless track.

[0040] The deviation angle between adjacent ballastless track slabs C is:

[0041]

[0042] The deviation displacement between adjacent plates is calculated based on the deviation angle θ0:

[0043] △X=Dsinθ0. Formula five

[0044] Step 5: According to the calculated deviation displacement △X, adjust the infrared receiver of the ballastless track slab C of the sliding reference system of the slide rail 13 to the deviation displacement △X from the center of the slab by the offset distance, wherein the infrared receiver for adjusting the offset distance is installed at the rear end of the ballastless track slab C.

[0045] Step 6: Turn the vertical adjustment bolts 6 and the horizontal adjustment bolts 7 on the ballastless track plate C to be adjusted so that each infrared transmitter 14 and the infrared receiver are in the same horizontal plane, thus completing the fine adjustment of the ballastless track of the curved section.
