[0027] Beneficially, sliding grooves three 40 are respectively provided on the two baffles 21. Two ends of the sliding plate 23 respectively penetrate through the baffle 21 and are slidably connected with the sliding grooves three 40. A control rack 39 is fixedly provided on one side of each sliding groove three 40 away from the sliding rod 36. The two control racks 39 are located on the sides of the two baffles 21 away from each other. A limit block 19 fixedly connected with the baffle 21 is provided at the end of the control rack 39. A sliding frame 42 is slidably provided in each sliding groove three 40. A moving motor 43 is fixedly provided on one side of each sliding frame 42.

The sliding sleeve one 47 and the discharge head 46 move together with the sliding plate 23. During this process, the driving motor 17 is started.

[0028] Beneficially, the second sliding sleeve 53 is slidably connected to the fourth chute 41. Two guiding plates 52 are respectively and fixedly provided at two ends of the carrier plate 24. A control rod 51 is provided between the second sliding sleeve 53 and one of the guiding plates 52. The control rod 51 is rotatably connected to the carrier plate 24.

The wedge-shaped block 48 is rotatably connected to the inner wall of the control groove 50 through a connecting pin 49 and a torsion spring. The wedge-shaped block 48 cooperates with the sliding plate 23; a middle section of the suspension rod 54 is of a "V" shaped structure. The inner diameter of the rolled anti-cracking sticker is larger than the diameter of the suspension rod 54. The rolled anti-cracking sticker has a certain toughness and allows bending. The unique "V" shaped structure of the suspension rod 54 enables the rolled anti-cracking sticker to be centered and the two sides to be upturned. During the paving process, the middle of the anti-cracking sticker contacts the target crack first, which is beneficial to discharging air bubbles from both ends of the anti-cracking sticker during the subsequent compaction process; the unrolling and rewinding of the anti-cracking sticker rely on manual fixation and cutting. It should be noted that when the two baffles 21 do not move to the position where they are farthest apart, there is not enough space for the carrier plate 24 and the guide rail 25 to move between the two baffles 21. When the wedge-shaped block 48 and the sliding plate 23 cooperate and the sliding plate 23 returns, the carrier plate 24 is limited. The wedge-shaped block 48 overcomes the torsion of the torsion spring, and the wedge-shaped block 48 rotates relative to the inner wall of the control groove 50, and the wedge-shaped block 48 breaks free from the restraint. Therefore, the carrier plate 24 can remain stationary without affecting the normal reciprocation of the sliding plate 23.

[0029] A method for reinforcing and repairing road surface defects includes the following steps: S1. Scanning; using infrared scanning combined with sonar detection to obtain the cracking trajectory of the road surface cracks in the target section, screening out the transverse cracks whose crack lengths, widths and depths meet the requirements, and selecting one of the cracks for construction to obtain the target crack; S2. Marking; selecting a point P outside the target crack as the reference point, obtaining the coordinate information of the target crack, obtaining the line segment l2 passing through the two end points of the target crack, and the coordinates of the midpoint O of the line segment; S3. Positioning; using the road surface defect reinforcement and repair device, moving by operating the engineering vehicle, and cooperating with starting the rotation motor 33, and real-time feedback of the coordinates of the positioning module, so that the center position of the control board 26 coincides with the point O, and the plane where the control board 26 is located coincides with the line segment l2; S4. Calibration: Control the two baffles 21 to move to both sides through the control motor 29, and use the monitoring modules 20 on both sides to monitor the target crack until the monitoring module 20 loses the target, obtaining the coordinates of two points a and b where the target crack fluctuates farthest to both sides, and the straight lines l1 and l3 passing through points a and b respectively and parallel to the line segment l2. Determine the distances from points a and b to the line segment l2. If the distances of the two are equal, directly proceed to the next step. If the distances of the two are not equal, correct the line segment l2 to the line segment l5, where the distances from the line segment l5 to points a and b are equal, and obtain the coordinates of the midpoint O' of the line segment l5; S5. Crack Sealing: Operate the engineering vehicle to move, and cooperate with starting the rotation motor 33 to provide real-time feedback on the coordinates of the positioning module, so that the central position of the control board 26 coincides with point O', and the plane where the control board 26 is located is parallel to the line segment l2; Cooperate with starting the moving motor 43 and the driving motor 17 to control the discharge head 46 to move along the trajectory of the target crack, and use the air pump and the connecting pipe to make the epoxy resin filler enter the target crack during the movement of the discharge head 46; S6. Crack Patching: Cut the crack-resistant tape with a suitable size according to the distance between the straight lines l1 and l3 to obtain a roll of crack-resistant tape that matches the width of the target crack, install it on the suspension rod 54, use the control rod 51 to make the bearing plate 24 move synchronously with the sliding plate 23, and control the suspension rod 54 and the roll of crack-resistant tape to move synchronously through the moving motor 43, so that the roll of crack-resistant tape covers the set area S.

[0030] Advantageously, in the step S4, if the distances from points a and b to the line segment l2 are not equal, calculate the perpendicular line l4 from point a to the straight line l1, and translate the line segment l2 along the direction of the perpendicular line l4 so that it passes through the midpoint of the perpendicular line l4, obtaining the line segment l5 and the coordinates of the midpoint O' of the line segment l5; In the step S6, the set area S is a rectangular area composed of the line segments m1, m2, n1, and n2, where the line segments m1, m2, and l5 are parallel respectively, and the line segments n1, n2, and l4 are parallel respectively. The distances from the two endpoints of the target crack to the line segments n1 and n2, the distance from point a to the line segment m1, and the distance from point b to the line segment m2 are all constants λ.

[0031] The working principle of the present invention: In the initial stage of construction, the target road section is closed for inspection and cleaning, and longitudinally cracked areas and large-scale cracked areas such as cobweb-like cracks are preliminarily excluded. Infrared scanning combined with sonar detection is used to check the remaining areas one by one to obtain the trajectories of a large number of small cracks. These cracks are further screened. Cracks with tortuous and extended trajectories are segmented at their turning positions, and cracks with overly long cracking trajectories are segmented to obtain cracks with a length within 2.5 - 15 m and a single extension direction. After marking and numbering, a pavement defect reinforcement and repair device is used to construct each one, and one of the cracks is used as the target crack for construction.

[0032] In one embodiment of the present invention, the included angle α between the target crack and the roadbed L is 65°, 45° < α < 80°, which is an inclined transverse crack, and the construction method is as shown in the appendix Figure 8 as follows: In the initial state, the fixed beam 12 is fixedly connected to the engineering vehicle. The mounting plate 16 is parallel to the fixed beam 12, the control plate 26 is centered, the two baffles 21 are close to the control plate 26, the two sliding frames 42 are respectively located at the ends of the mounting plate 16, and the mounting plate 16 is at a horizontal high position; the sliding plate 23 and the bearing plate 24 are respectively located at one end of the control plate 26, but the wedge block 48 does not connect the two. The control rod 51 is in its counterclockwise limit rotation posture, and the control rod 51 cannot rotate further counterclockwise. When there is no external force, the torsion spring keeps the wedge block 48 in the state as shown in the appendix Figure 7 as shown.

[0033] Near the construction site, a point P is selected as the reference point outside the area where the target crack is located to obtain the line segment l2 passing through the two end points of the target crack and the coordinates of the midpoint O of this line segment; the position and posture of the control plate 26 are controlled in real time through the positioning module, so that the center position of the control plate 26 coincides with point P, the engineering vehicle is controlled to travel along the planned path, and the rotation motor 33 is started in cooperation. The coordinates of the positioning module are fed back in real time, so that the center position of the control plate 26 coincides with point O, and the plane where the control plate 26 is located coincides with the line segment l2.

[0034] The control motor 29 is started. The control motor 29 controls its output shaft to drive the driving gear 28 to rotate. The driving gear 28 transmits torque to the driven gear 35 through the transmission assembly. The threaded rod 22 and the driven gear 35 rotate synchronously. Under the action of the thread, the two threaded blocks 37 move away from the driven gear 35 synchronously. The baffle 21 and the sliding rod 36 move together with the threaded block 37. The second chute 38 and the guide rail 25 slide, and the two baffles 21 move to both sides. The target crack is monitored by the monitoring modules 20 on both sides until the baffle 21 covers the target crack and the monitoring modules 20 lose the target. The monitoring modules 20 record the position coordinates of the last monitored target to obtain the coordinates of the two points a and b where the target crack fluctuates farthest to both sides, and the straight lines l1 and l3 passing through points a and b respectively and parallel to the line segment l2.

[0035] Judge the distances from point a and point b to line segment l2. The probability that the two distances are equal is very low. If they are exactly equal, skip the proofreading step and directly perform the operations of caulking and patching; if the two distances are not equal, calculate the perpendicular line l4 from point a to line l1, and translate line segment l2 along the direction of perpendicular line l4 so that it passes through the midpoint of perpendicular line l4 to obtain line segment l5 and the coordinates of the midpoint O' of line segment l5; move the construction vehicle through operations and cooperate with starting the rotation motor 33 to feed back the coordinates of the positioning module in real time, so that the center position of the control board 26 coincides with point O', and make the plane where the control board 26 is located parallel to line segment l2.

[0036] First, start the lifting cylinder 13, control the extension of its piston rod, cause the lifting plate 14 and the rotating frame 11 to slide, change the horizontal position of the mounting plate 16 to a low position, make the bottom of the baffle 21 contact the ground, start the moving motor 43, and the moving motor 43 controls its output shaft to drive the moving gear 44 to rotate. Under the meshing action of the moving gear 44 and the control rack 39, the moving gear 44, the moving motor 43 and the sliding frame 42 move. The sliding frame 42 slides along the chute three 40, and the sliding frame 42 drives the sliding plate 23 to move. Start the driving motor 17 to control the discharge head 46 to move along the trajectory of the target crack; use the air pump and the connecting pipe to cooperate with the moving discharge head 46 to make the epoxy resin filler enter the target crack. The epoxy resin silo is fixed on the mounting plate 16, and the connecting pipe is arranged on the lower side of the mounting plate 16. After the epoxy resin caulking is completed, keep the position of the baffle 21 unchanged and start the hot air blower.

[0037] After curing is completed, according to the distance between the straight line l1 and the straight line l3, cut an anti-cracking sticker of appropriate size to obtain a rolled anti-cracking sticker that matches the width of the target crack, and install it on the suspension rod 54. Start the lifting cylinder 13, control the contraction of its piston rod, so that the lifting plate 14 and the rotating frame 11 slide, and the mounting plate 16 changes its horizontal position to a high position. Start the driving gear 28 to control the two side baffles 21 to move to the farthest position from each other, giving way to the bearing plate 24 and the guide rail 25. Start the moving motor 43, control one of the sliding frames 42 to slide and push the sliding plate 23 to move, so that the sliding plate 23 approaches the bearing plate 24. During this process, after the sliding plate 23 contacts the wedge block 48, the thrust is not enough to overcome the torsion of the torsion spring to make it rotate. Therefore, the relative postures of the wedge block 48 and the control rod 51 remain unchanged. Until the wedge block 48, the control rod 51, and the bearing plate 24 move to the end where the sliding sleeve two 53 contacts the chute four 41, and the sliding sleeve two 53 cannot move further towards the end, the inclined lower surface of the wedge block 48 contacts the upper surface of the sliding plate 23 and overlaps. The wedge block 48 and the control rod 51 are lifted, and the control rod 51 rotates relative to the bearing plate 24 until the side surface of the sliding plate 23 crosses the wedge block 48. At this time, control the sliding plate 23 to return through the other moving motor 43. Since there is room for the bearing plate 24 and the guide plate 52 to move, the pulling force of the sliding plate 23 still cannot overcome the torsion of the torsion spring to make it rotate. The sliding plate 23 will drive the bearing plate 24 to move together through the wedge block 48 and the control rod 51, thereby driving the suspension rod 54 and the rolled anti-cracking sticker to move and cover the set area S.

[0038] During the above process, the set area S is a rectangular area composed of the line segment m1, the line segment m2, the line segment n1, and the line segment n2, where the line segment m1, the line segment m2, and the line segment l5 are parallel respectively, and the line segment n1, the line segment n2, and the line segment l4 are parallel respectively. The distances from the two end points of the target crack to the line segment n1 and the line segment n2, the distance from the point a to the line segment m1, and the distance from the point b to the line segment m2 are all constants λ. The constant λ is the minimum distance requirement for the edge of the anti-cracking sticker from any position of the target crack.

[0039] In another embodiment of the present invention, the included angle α' between the target crack and the roadbed L' is 84°, α' > 80°, which belongs to a crack that is nearly perpendicular to the roadbed. Another construction method as shown in the appendix Figure 9 is adopted. Different from the above embodiment: the set area S' is perpendicular to the roadbed L'. In the case of the same crack shape, the distances from the two end points of the target crack to the line segment n1' and the line segment n2', the distance from the point a' to the line segment m1', and the distance from the point b' to the line segment m2' are also all constants λ. Although the area of S' is slightly larger than the area of S, it is still within the range that the construction loss can bear, and the construction difficulty can be reduced and the construction efficiency can be improved by means of manual assistance for crack patching.
