Asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by traffic and natural factors, making the road surface smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] When paving asphalt pavement, a precise horizontal line is needed to adjust the flatness so that the paved road surface can be flat and the quality of the road surface flatness can be guaranteed. In the past, a steel wire rope was pulled on a horizontal rod of a bracket, and the steel wire rope needed to be tied and fixed on the horizontal rod with wire. The wire at the binding point was higher than the steel wire rope. When paving, the paving flatness was adjusted by the horizontality of the steel wire rope. Since the steel wire rope was fixed on the horizontal rod with wire, it was very inconvenient and difficult to adjust. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model provides a technical solution: a limit support device for leveling an asphalt roadbed surface, comprising a support seat 1, a telescopic cylinder 2, an extension rod 3, a vertical rod 4, a connecting block 5, a level 6, a moving rod 7, a friction block 8, a limit block 9, a spring 10, a pulley 11, a slide 12, a connecting piece 13, and a wire rope 14.

[0027] Example 1

[0028] The limit support device for leveling the asphalt roadbed surface is provided with an adjustment structure, which can adjust the horizontal height by pressing the moving rod 7, specifically:

[0029] The support seat 1 is set to a triangular structure, which is characterized in that it also includes a telescopic cylinder 2, which is installed on the side surface of the support seat 1, and the telescopic cylinder 2 is connected to an adjustment structure, which can determine the paving height of the asphalt pavement through the moving rod 7. The adjustment structure includes an extension rod 3, which is installed through the inside of the telescopic cylinder 2, and both ends of the extension rod 3 are connected to the telescopic cylinder 2, the side surface of the telescopic cylinder 2 is connected to a vertical rod 4, and the front surface of the vertical rod 4 is provided with a groove, and the moving rod 7 is slidably installed in the groove, and the rear end of the moving rod 7 is connected to a spring 10, and the other end of the spring 10 is installed on the inner wall surface of a limit block 9, and a pulley 11 is installed on the rear surface of the limit block 9, and the limit block 9 is slidably installed in a slide groove 12, and the slide groove 12 is installed on the inner wall surface of the vertical rod 4, and the outer surface of the moving rod 7 is provided with a friction block 8, and the front surface of the friction block 8 is frictionally connected to the front surface of the inner wall of the vertical rod 4, and the rear end of the moving rod 7 slides through the limit block 9.

[0030] When the limit support device for leveling the asphalt roadbed surface is used, first, Figure 1As shown, the two telescopic cylinders 2 are pulled apart to extend the extension rod 3, and then the two support bases 1 are respectively placed on both sides of the road, and then the moving rod 7 is adjusted, as shown in FIG. Figure 4 As shown, the moving rod 7 is pressed toward the inside of the vertical rod 4, so that the rear end of the moving rod 7 squeezes the spring 10, and the rear end of the moving rod 7 slides and embeds into the inside of the limit block 9. At this time, the friction block 8 set on the outer surface of the moving rod 7 and the front surface of the inner wall of the vertical rod 4 will lose friction. Then the moving rod 7 is moved downward, so that the moving rod 7 drives the limit block 9 downward. Since the limit block 9 is slidably installed in the slide groove 12, the pulley 11 on the rear surface of the limit block 9 slides in the slide groove 12. After reaching the appropriate position, the moving rod 7 is released, so that the spring 10 behind the moving rod 7 rebounds, so that the friction block 8 set on the outer surface of the moving rod 7 is frictionally fixed with the front surface of the inner wall of the vertical rod 4, so that the moving rod 7 is fixed at the desired position.

[0034] When adjusting the moving rod 7, the level 6 is turned on. When the moving rod 7 moves, it will drive the connecting block 5 installed in a sleeve-type manner on the outer surface of the vertical rod 4, so that the level 6 on the lower surface of the connecting block 5 moves at the same time. The height of the moving rod 7 can be kept accurate through the level 6, and then a steel wire rope 14 is connected to the connecting piece 13 at the front end of the moving rod 7.
