Description

Technical Field

[0001] This utility model belongs to the field of road engineering construction and relates to a device that can effectively adjust the paving thickness at the edge of the paved structural layer during the paving operation of graded crushed stone or other unbound material structural layers using a paver. Background Technology

[0002] When constructing graded crushed stone or other unbound structural layers for roads, pavers are often used for paving. However, since the paving material is loose, "edge collapse" is prone to occur on both sides of the road, resulting in inconsistent paving thickness between the sides and the middle of the road, which affects the construction quality of the upper structural layer of the road. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a paver edge paving thickness adjustment device. During the paving process, the paving thickness at the edge of the paving structure layer can be flexibly adjusted according to requirements, effectively improving the elevation control accuracy of the paving structure edge.

[0004] The technical solution of this utility model is as follows:

[0005] A paver construction layer edge paving thickness adjustment device is characterized by: a chute, a hook at the bottom of the upper end of the chute, a vertical support plate welded to each side of the lower end of the chute, a roller disposed between the lower ends of the two vertical support plates below the chute, the roller shafts of the roller being rotatably connected to the lower ends of the two vertical support plates respectively, a horizontal support plate welded to each side of the lower end of the chute, the front ends of the two horizontal support plates extending a certain length in front of the lower end of the chute, a vertical connecting plate welded to the front ends of the two horizontal support plates respectively, a scraper disposed between the two vertical connecting plates, the scraper being bolted to the two vertical connecting plates on both sides, and the bottom edge of the scraper being higher than the bottom edge of the roller.

[0006] This utility model is installed on both sides of the rear of the paver. In response to the collapse phenomenon after paving, a layer of compensating material is spread on both sides through a chute, and the compensating material is leveled by a scraper. The height of the scraper can be flexibly adjusted to facilitate the control of the height of the compensating material and ensure the construction quality of the subsequent road surface layer. Attached Figure Description

[0007] Figure 1 This is a side view of the present invention;

[0008] Figure 2 This is a front view of the present invention. Detailed Implementation

[0009] like Figure 1 , Figure 2As shown, this utility model includes a chute 1, with a hook 2 at the bottom of the upper end of the chute, and a vertical support plate 3 welded to each side of the lower end of the chute. A roller 4 is arranged between the lower ends of the two vertical support plates below the chute, with the two ends of the roller 4 rotatably connected to the lower ends of the two vertical support plates 3 respectively. A horizontal support plate 5 is also welded to each side of the lower end of the chute 1, with the front ends of the two horizontal support plates 5 extending a certain length in front of the lower end of the chute. A vertical connecting plate 6 is welded to the front ends of the two horizontal support plates 5 respectively, and a scraper 7 is arranged between the two vertical connecting plates 6. The scraper 7 is connected to the two vertical connecting plates on both sides by bolts 8, and the bottom edge of the scraper 7 is higher than the bottom of the roller 4.

[0010] In a specific implementation of this utility model, to facilitate the adjustment of the height of the scraper 7, a vertical through hole 9 can be provided on each vertical connecting plate 6. The bolt 8 connecting the scraper and the vertical connecting plate passes through the vertical through hole 9 on the vertical connecting plate and is tightened with a nut 10. When it is necessary to adjust the height of the scraper, the nut can be loosened first, the bolt can be slid along the vertical through hole to the appropriate position, and then the nut can be tightened.

[0011] The method of using this utility model is as follows:

[0012] like Figure 1 , Figure 2 As shown, two devices of this invention are respectively installed on both sides of the rear of the paver 11. The chute 1 of each device is connected to the paver 11 via a hook 2. The bottom of the chute is supported on the top of the rear end of the paver, and the roller below the chute is flush with the bottom of the paver's paving slab. The chute is dragged along with the paver as it moves.

[0013] When a paver is paving graded crushed stone or other unbound structural layers on the road, in response to the collapse phenomenon on both sides of the road, compensating material is manually added to the chute. The compensating material is spread from the bottom of the chute to both sides of the road. As the paver moves, the scraper flattens the compensating material to form a compensating layer 12.

[0014] Since the compensation layer is not compacted by a paver, the loose thickness of compensation layer 12 needs to be greater than the thickness of the inner pavement. The specific thickness can be controlled by adjusting the height of the scraper as needed. The compensation layer can be compacted with a roller during the later construction of the upper structural layer.
