[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] An embodiment provided by the present invention: Figure 1 As shown, a highway construction and maintenance device, such as Figure 1 As shown, it includes a fixed slot rod 1, a moving part 2, a positioning mechanism 3 and a discharging assembly 4.

[0024] like Figure 1 As shown, a vehicle body connector 13 is installed outside the side limiter 12, the other end of which is fixed to a road maintenance vehicle. This device is installed at the rear of the road maintenance vehicle. The discharging assembly 4 transfers asphalt from the vehicle to the cracks in need of repair. Precise positioning of the discharging area of the discharging assembly 4 ensures that the asphalt is accurately repaired at the cracks.

[0025] The moving part 2 is slidably connected to the fixed slot rod 1, as shown in FIG. Figure 2As shown, both ends of the fixed groove rod 1 are fixedly connected to the side limit members 12, and baffles 21 are provided on the side edges of the movable member 2 in opposite directions of the top and bottom. A first hydraulic press 14 is provided between the side limit members 12 and the movable member 2, and two groups of first hydraulic presses 14 are provided between the side limit members 12 and the movable member 2, wherein the body of one group of first hydraulic presses 14 is fixed above the baffle 21 on one side, and the output end is fixed inside the top baffle 21 of the movable member 2; the body of the other group of first hydraulic presses 14 is fixed below the baffle 21 on the other side, and the output end is fixed inside the bottom baffle 21 of the movable member 2. As shown Figure 3 As shown, the middle part of the movable member 2 has a groove 22. The movable member 2 with the groove 22 matches the shape of the fixed slot rod 1. The top and bottom positions of the groove 22 are provided with rollers 221, which are slidably connected to the fixed slot rod 1. Under the joint drive of the two sets of first hydraulic presses 14, the movable member 2 can be translated on the fixed slot rod 1, and the movable member 2 and the positioning mechanism 3 are controlled laterally to change position. During the movement process, the movable member 2 is inserted into the notch of the fixed slot rod 1, and the roller 221 at the groove 22 of the movable member 2 slides inside the fixed slot rod 1, thereby improving the stability during movement and maintaining the stable discharge of the discharging assembly 4.

[0026] like Figure 3 and Figure 4 As shown, the positioning mechanism 3 includes a moving part connecting member 31, a fixed seat 32, a second hydraulic machine 33 and a discharge head positioning assembly 34. The positioning mechanism 3 is fixedly connected to the moving part 2, the moving part connecting member 31 is fixedly connected to the side of the moving part 2 away from the fixed groove rod 1, and the moving part connecting member 31 is fixedly connected to the fixed seat 32.

[0027] like Figure 4 As shown, the discharge head positioning assembly 34 is vertically slidably connected to the fixed seat 32, the body of the second hydraulic press 33 is fixed to the bottom of the fixed seat 32, and the output end of the second hydraulic press 33 is fixedly connected to the discharge head positioning assembly 34. Figure 5 As shown, the discharging head positioning assembly 34 comprises a movable base 341, a third hydraulic pressure device 342, and a discharging head fixing member 343. A roller 3411 is centrally located within the movable base 341 and rotatably connected to the movable base 341. A through slot is centrally located within the fixing base 32, flanked by rails 321, on which the roller 3411 slides. Driven by the second hydraulic pressure device 33, the overall height of the discharging head positioning assembly 34 is adjusted vertically. The roller 3411 of the movable base 341 slides on the rails 321, maintaining the stability of the height adjustment of the discharging head positioning assembly 34.

[0028] like Figure 5As shown, the discharge head fixing member 343 is telescopically connected to the movable base 341. The main body of the third hydraulic press 342 is fixed to the movable base 341, and the output end of the third hydraulic press 342 is fixedly connected to the discharge head fixing member 343. Under the driving action of the third hydraulic press 342, the distance between the discharge head fixing member 343 and the movable base 341 is adjusted, allowing the discharge head fixing member 343 to move forward and backward.

[0029] The discharge assembly 4 is mounted on the discharge head fixing member 343, as shown in FIG. Figure 6 As shown, the discharge assembly 4 includes a connecting pipe 41, a discharge seat 42, and a discharge head 43. The connecting pipe 41 is disposed at one end of the discharge seat 42, and the discharge head 43 is threadedly connected to the other end of the discharge seat 42. The discharge head 43 is plugged into the discharge head fixture 343. Depending on the size of the crack to be repaired, the discharge head 43 of different specifications can be replaced to ensure that the discharge head 43 matches the crack size and improve the repair effect. The discharge head 43 is hung on the discharge head fixture 343. The discharge head 43 is made of thermal insulation material. In special circumstances, the discharge head 43 can be removed and manually aligned to repair the road crack in a specific location.

[0030] During operation, the device can position the discharging direction of the discharging head 43 at the precise location to be repaired without moving the entire device by moving the movable member 2 horizontally on the fixed slot rod 1, adjusting the overall height of the discharging head positioning assembly 34 up and down, and moving the discharging head fixing member 343 back and forth. At the same time, in the case of larger cracks, the device can adjust the discharging head 43 in the horizontal, front-to-back, or height directions while discharging asphalt according to the direction of crack repair, thereby filling the cracks quickly and efficiently. Furthermore, the precise positioning of the discharging position ensures that the asphalt coverage position does not exceed the preset range, thus avoiding unevenness of the repaired road surface.
