Description

Technical Field

[0001] The utility model relates to the field of road construction, in particular to an asphalt pavement layer paving device. Background Art

[0002] A paver is a device that spreads various materials of the road base and surface layer evenly on the road, and then performs preliminary compaction and leveling. Pavers can be divided into two types according to the walking mode: crawler type and tire type, and can be divided into four types according to the paving width: small, medium, large, and super large. They are mainly used for paving construction of large-area roads such as highways, airports, docks, and squares.

[0003] Due to the different widths of the road surface, there is a phenomenon that the width of the road surface to be paved is greater than the designed paving width of the paver. In order to ensure that the edge of the road is paved in place, manual shoveling and spreading of materials can only be used on site to fill the missed parts of the edge. However, manual paving is not only time-consuming and labor-intensive, but also easily causes segregation of the mixture, affecting the paving quality.

[0004] Patent No. CN217203480U discloses a paver baffle device that is convenient for adjusting the paving width. The device meets the adjustment requirements of the movable baffle by setting a wire rope to pull the movable baffle, thereby achieving the effect of adjusting the pavement paving width. However, it was found during use that since the wire rope was set between the inner side of the movable baffle and the paver frame, the asphalt would submerge the wire rope during the asphalt paving operation, and the asphalt would adhere to the wire rope tensioner, affecting the tensioner's control over the wire rope, thereby affecting the use effect of the paver. It is necessary to improve it. Summary of the invention

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work, any modifications, equivalent replacements, improvements, etc., should be included in the protection scope of the utility model.

[0027] like Figures 1 to 6 As shown, this embodiment discloses an asphalt pavement layer paving device, including a paver main body 6, both ends of the paver main body 6 in the length direction are provided with baffle mechanisms, a flat material mechanism is provided between the two baffle mechanisms, and the flat material mechanism is fixedly connected to the paver main body 6;

[0028] A conveying mechanism is arranged at the rear side of the paver body 6, and the conveying mechanism is located between the paver body 6 and the flat material baffle 3, and the conveying mechanism is transmission-connected to the paver body 6. The connection structure of the conveying mechanism belongs to the conventional structure on the paver, and this technical solution only lists one of the structures, and the conveying mechanism structures in other prior arts can also be used in this technical solution, and can have the same technical effect.

[0029] The conveying mechanism includes a power shaft 11, a first auger 7, and a second auger 8. The length direction of the power shaft 11 is consistent with the length direction of the flat material baffle 3. A transmission assembly 9 is provided in the middle of the power shaft 11 and is connected to the paver body 6 through the transmission assembly 9. The first auger 7 and the second auger 8 are respectively located on both sides of the transmission assembly 9 and the first auger 7 and the second auger 8 are fixedly wound around the outside of the power shaft 11. The first auger 7 and the second auger 8 are both arranged in a spiral shape and the spiral directions of the first auger 7 and the second auger 8 are opposite.

[0030] The transmission assembly 9 includes a fixed shell 91, a pulley 92, and a power belt 93. The front end of the fixed shell 91 is open and the open end is fixedly connected to the paver body 6. The side walls of the fixed shell 91 are provided with through holes 911. The middle part of the power shaft 11 is inserted into the through holes 911 and the power shaft 11 can rotate in the through holes 911; a pulley 92 is provided in the fixed shell 91, and the pulley 92 is fixedly sleeved on the outside of the power shaft 11. One end of the power belt 93 is wound around the outside of the pulley 92, and the other end of the power belt 93 extends from the open end of the fixed shell 91 into the paver body 6 and is connected to the power equipment in the paver body 6. The specific structure is as follows Figure 6 shown.

[0031] When the asphalt material is being laid, the asphalt material will fall to the front side of the paver body. As the paver body moves forward, the conveying mechanism will come into contact with the asphalt material. Under the action of the transmission assembly and the first and second auger, the asphalt material will be spread to both sides of the length direction of the paver body, so that the asphalt material is laid between the two baffle mechanisms. As the paver body continues to move forward, the leveling mechanism will pass over the laid asphalt material and scrape it flat, finally realizing the pavement laying operation of the asphalt material.

[0032] The baffle mechanism includes a fixed plate 1 and a movable plate 2. The fixed plate 1 is fixedly connected to one end of the paver body 6. One end of the fixed plate 1 extends to the rear side of the paver body 6 and the end is rotatably connected to the movable plate 2 via a hinge 12. The end of the movable plate 2 away from the fixed plate 1 is connected to a pulling ring 21 and is connected to one end of a pulling rope 51 via the pulling ring 21.

[0033] When paving a wider road surface, the length of the pulling rope can be increased. The asphalt material will be spread between the two movable plates under the action of the conveying mechanism, and the movable plates in the two baffle mechanisms will be pushed outward at a certain angle under the extrusion pressure. After the movable plates are pushed outward, the pulling rope is in a taut state. At this time, the maximum distance between the two movable plates forms the paving width of the road surface; therefore, the paving width of the road surface can be adjusted by adjusting the length of the pulling rope.

[0034] The flat material mechanism includes mounting rods 10 and flat material baffles 3. One ends of the two mounting rods 10 are respectively fixedly connected to the two sides of the paver body 6, and the other ends of the two mounting rods 10 are fixedly connected to the flat material baffles 3. The flat material baffle 3 is located between the movable plates 2 of the two baffle mechanisms. The length direction of the flat material baffle 3 is consistent with the length direction of the paver body 6. Adjustment components are provided at both ends of the length direction of the flat material baffle 3. A pulling component 5 is provided on the outer side of the flat material baffle 3. The pulling component 5 is respectively connected to the movable plates 2 of the two baffle mechanisms.

[0035] The adjustment assembly includes an adjustment plate 4, on which a plurality of rows of first bolt holes 41 are arranged at equal intervals along the length direction of the flat material baffle 3, and each row of first bolt holes 41 includes two longitudinally arranged bolt holes; at least one row of second bolt holes corresponding to the first bolt holes 41 is arranged at one end of the flat material baffle 3 close to the baffle mechanism (which is arranged corresponding to a row of first bolt holes, not drawn in the figure), the adjustment plate 4 is attached in parallel to the outer side of the flat material baffle 3 and any row of first bolt holes 41 is connected to the second bolt holes by fixing bolts 42; after the adjustment plate 4 is connected to the flat material baffle 3, the bottom end height of the adjustment plate 4 is flush with the bottom end height of the flat material baffle 3.

[0036] After the movable plate is rotated outward and spread open, the position of the adjustment plate is adjusted to achieve the operation of covering the gap between the movable plate and the flat material baffle. When paving operations are performed, the adjustment plate plays the same role as the flat material baffle, and it and the bottom of the flat material baffle together perform a flattening operation on the asphalt material. When adjusting the adjustment plate, it is only necessary to select a suitable first bolt hole and bolt it to the second bolt hole on the flat material baffle.

[0037] like Figure 4 , Figure 5As shown, the pulling assembly 5 is arranged at the rear side of the flat material baffle 3, and it will not have any contact with the asphalt material; the pulling assembly 5 includes a fixed pipe 53, a rotating roller 52, and a pulling rope 51; the fixed pipe 53 is fixedly connected to the outer center position of the flat material baffle 3 and the axial direction of the fixed pipe 53 is perpendicular to the flat material baffle 3, one end of the rotating roller 52 is inserted into the fixed pipe 53 and the rotating roller 52 can rotate relative to the fixed pipe 53; the other end of the rotating roller 52 is provided with a mounting through hole 521, and the mounting through hole 521 penetrates the rotating roller 52 along the radial direction of the rotating roller 52, and one end of the pulling rope 51 is connected to the movable part of one of the baffle mechanisms The rotating roller 52 is connected to the plate 2, and the other end of the pulling rope 51 passes through the installation hole 521 and is connected to the movable plate 2 of another baffle mechanism; the outer peripheral wall of one end of the rotating roller 52 inserted into the fixed pipe 53 is provided with a plurality of through holes 522, the axial direction of the plurality of through holes 522 is consistent with the radial direction of the rotating roller 52, and the plurality of through holes 522 are arranged at equal intervals along the circumferential direction of the rotating roller 52; the outer wall of the fixed pipe 53 is provided with positioning holes 531 corresponding to the through holes 522; when the rotating roller 52 is connected to the fixed pipe 53, a latch member 54 is inserted between the positioning hole 531 and any through hole 522.

[0038] The end of the rotating roller 52 away from the fixed pipe 53 is provided with a hand piece 523 for convenient hand-held rotation. The outer diameter of the hand piece 523 is larger than the cross-sectional outer diameter of the rotating roller 52 to prevent the pulling rope 51 wrapped around the outside of the rotating roller 52 from falling off the end of the rotating roller 52.

[0039] The pulling assembly is mainly used to control the length of the pulling rope. When the length of the pulling rope needs to be shortened, the pin is taken out from the positioning hole and the through hole, and then the rotating roller is rotated. The rotating roller will drive the pulling rope in the installation through hole to rotate together, and the pulling rope is wrapped around the outer circumference of the rotating roller. At this time, the length of the pulling rope is shortened, and then the pin is reinserted into the positioning hole and the through hole corresponding to the positioning hole; when the length of the pulling rope needs to be increased, the operation is the same, and only the rotating roller needs to be rotated in the opposite direction.

[0040] The utility model adopts a design in which a pulling assembly is provided at the outer side of the flat material baffle and the movable plate is pulled by the pulling assembly. The movable plate can be pulled and limited by the pulling assembly, and the asphalt material can be prevented from adhering to the pulling assembly and affecting the adjustment and control operation of the pulling rope by the pulling assembly, thereby effectively improving the use effect of the pulling assembly. In addition, the utility model adopts a design in which an adjustment assembly is provided at both ends of the flat material baffle, so that when paving a road surface with a larger width, after adjusting the position of the movable plate, the position of the adjustment plate in the adjustment assembly can be adjusted, so that the bottom end of the adjustment plate and the bottom end of the flat material baffle can perform a flat material operation on the asphalt material together, thereby avoiding the situation in which the asphalt material paved at the position between the movable plate and the flat material baffle after adjustment cannot be leveled and needs to be leveled manually, thereby reducing the workload of construction personnel and further improving the use effect of the paver.
