Description

Technical Field

[0001] The utility model relates to the technical field of road traffic, in particular to a vehicle pressurizing device. Background Art

[0002] Cold-mix, cold-laid, thin-layer overlay technology has been gradually adopted in highway maintenance and repair, but its construction equipment primarily relies on slurry sealers and pavers. While capable of completing cold-mix, cold-laid thin-layer overlays, these machines are not specialized and present several challenges and limitations. Because cold-mix, cold-laid mixtures utilize large-size, graded crushed stone as aggregate and highly viscous modified emulsified asphalt as a binder, the mixture exhibits high viscosity. Conventional slurry sealers, due to their limited weight, are prone to uneven paving and difficulty controlling thickness, impacting construction quality. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention proposes a vehicle pressurizing device that controls the downforce of the paving assembly by varying the pressure on the drive rod, thereby controlling the degree of compaction and thickness uniformity.

[0004] The vehicle pressurizing device according to the present utility model comprises:

[0005] A vehicle, comprising a chassis and a bracket disposed above the chassis;

[0006] a connecting rod assembly, one end of which is rotatably connected to the chassis;

The driving rod assembly can be retracted to press down or lift the paving assembly.

[0009] According to the vehicle pressurizing device of the embodiment of the present invention, the material to be paved is transported by a vehicle, and the material to be paved can be delivered to the road surface, and the material to be paved is compacted by the paving assembly.

In this way, the paving assembly is installed and supported by the connecting rod assembly and the driving rod assembly. When necessary, the driving rod assembly can drive the paving assembly to press down on the road surface, so that the material to be paved on the road surface can be compacted. In addition, by controlling the degree of downward pressure of the driving rod assembly, the consistency of the paving thickness can be ensured. By precisely controlling the thickness of the material, the road surface can be made more uniform, avoiding the uneven thickness problem that is prone to occur in traditional equipment. Secondly, the device ensures the flatness of the paving layer by evenly distributing the material, improving the construction quality and the service life of the overall road surface.

[0014] According to one embodiment of the present invention, the bottom surface of the paving box is higher than the bottom surfaces of the first mounting plate and the second mounting plate.

[0015] According to one embodiment of the present invention, the bottom surface of the paving box gradually slopes downward in a direction away from the chassis.

[0029] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, or indirect connections through an intermediary.

Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples without contradiction.

[0034] Currently, there are no relevant specifications to describe and define the construction equipment for cold-mix, cold-laid thin-layer overlays. Although cold-mix, cold-laid thin-layer overlay technology has gradually been applied in the process of highway maintenance and repair, its construction equipment mainly relies on slurry sealers and pavers. Although these devices can complete the construction of cold-mix, cold-laid thin-layer overlays, they are not dedicated equipment and have some problems and limitations. First, because cold-mix, cold-laid mixtures use large-size graded crushed stone as aggregate and high-viscosity modified emulsified asphalt as a binder, the mixture has high viscosity. Ordinary slurry sealers are prone to problems such as insufficient paving uniformity and difficulty in controlling thickness during the paving process due to insufficient weight, which affects construction quality. In addition, during the paving process of cold-mix, cold-laid materials, traditional pavers often suffer from low construction efficiency and material waste due to equipment mismatch. They are also prone to problems such as material accumulation in the hopper and uneven material distribution in the paving box, which increases construction costs and environmental burdens.

[0035] In response to the above problems, the following Figures 1 to 3 A vehicle pressurizing device according to an embodiment of the present application is described.

[0036] The vehicle pressurizing device according to the present invention includes a vehicle 1, a connecting rod assembly, a paving assembly, and a drive rod assembly. The vehicle 1 includes a chassis 2 and a bracket 3 disposed above the chassis 2. One end of the connecting rod assembly is rotatably connected to the chassis 2. The paving assembly is connected to the end of the connecting rod assembly away from the chassis 2, and the end of the connecting rod assembly away from the chassis 2 is rotatably connected to the paving assembly. One end of the drive rod assembly is rotatably connected to the bracket 3, and the other end of the drive rod assembly is rotatably connected to the paving assembly. The end of the drive rod assembly connected to the paving assembly and the end of the connecting rod assembly connected to the paving assembly are spaced apart in a direction away from the chassis 2, and the distance between the end of the drive rod assembly connected to the paving assembly and the chassis 2 is greater than the distance between the end of the connecting rod assembly connected to the paving assembly and the chassis 2. The drive rod assembly is retractable to press down or lift the paving assembly. It should be noted that the location where the drive rod assembly is connected to the paving assembly is further away from the chassis 2 than the location where the connecting rod assembly is connected to the paving assembly, so that the extension and retraction of the drive rod assembly can cause the paving assembly to move in the height direction.

[0037] like Figure 1As shown, according to the vehicle pressurizing device of the embodiment of the present invention, the material to be paved is transported by vehicle 1, and the material to be paved can be delivered to the road surface, and the material to be paved is compacted by the paving assembly. The paving assembly is rotatably connected to the chassis 2 of the vehicle 1 through the connecting rod assembly. At the same time, the paving assembly is also rotatably connected to the bracket 3 of the vehicle 1 through the driving rod assembly. In this way, the paving assembly is installed and supported by the connecting rod assembly and the driving rod assembly. When necessary, the driving rod assembly can drive the paving assembly to press down the road surface, so that the material to be paved on the road surface can be compacted. In addition, by controlling the degree of downward pressure of the driving rod assembly, the consistency of the paving thickness can be ensured, and by precisely controlling the thickness of the material, the road surface can be made more uniform, avoiding the uneven thickness problem that is prone to occur in traditional equipment. Secondly, the device ensures the flatness of the paving layer by evenly distributing the material, thereby improving the construction quality and the service life of the overall road surface. Finally, the design of the vehicle pressurizing device can achieve efficient compaction, enhance the adhesion of the material to the road surface, and ensure the compaction and durability of the road surface.

[0038] As will be understood, vehicle 1 is used to transport materials to a designated location. The connecting rod assembly, paving assembly, and drive rod assembly are mounted on the rear of vehicle 1, facilitating the spreading of materials along the road surface as vehicle 1 travels along the road. The paving assembly is rotationally supported by the connecting rod assembly, and the side of the paving assembly facing away from chassis 2 is connected to the drive rod assembly. This allows the paving assembly to be extended or retracted, thereby controlling the pressure applied by the paving assembly to the material. The material to be paved can be asphalt, gravel, concrete, or other materials, without limitation.

[0039] like Figure 2 As shown, according to one embodiment of the present utility model, the paving assembly includes a paving box 6, a first mounting plate 7 and a second mounting plate 8, the end of the connecting rod assembly away from the chassis 2 is rotatably connected to the paving box 6, and the end of the driving rod assembly away from the bracket 3 is rotatably connected to the paving box 6; the first mounting plate 7 is installed on one side of the paving box 6; the second mounting plate 8 is installed on the side of the paving box 6 away from the first mounting plate 7, and the first mounting plate 7 and the second mounting plate 8 are respectively arranged on the left and right sides of the paving box 6.

[0040] In this embodiment, the paving box 6 is used to press the material to be paved on the road surface. The first mounting plate 7 and the second mounting plate 8 are arranged on opposite sides of the paving box 6 to improve the pressing stability of the paving box 6. It should be noted that the side of the paving box 6 closest to the vehicle 1 is the front side, and the side facing away from the vehicle 1 is the rear side. The remaining two sides of the paving box 6 are the left and right sides, respectively. The first mounting plate 7 is installed on the left side of the paving box 6, and the second mounting plate 8 is installed on the right side of the paving box 6. The first mounting plate 7 and the second mounting plate 8 are symmetrically arranged to ensure that the two sides of the paving box 6 are evenly stressed.

[0041] like Figure 3As shown, according to one embodiment of the present invention, the bottom surface of the paving box 6 is higher than the bottom surfaces of the first mounting plate 7 and the second mounting plate 8. This creates a material storage space between the paving box 6, the first mounting plate 7, and the second mounting plate 8. As the vehicle 1 moves, the material to be paved can enter the storage space and be pressed and leveled by the paving box 6. Specifically, when the paving assembly is pressed downward, a certain distance is created between the paving box 6 and the ground, and the material to be paved fills this space, allowing the paving box 6 to be compacted. The first mounting plate 7 and the second mounting plate 8 prevent the material from overflowing to the left or right.

[0042] According to one embodiment of the present invention, the bottom surface of the paving box 6 gradually slopes downward in a direction away from the chassis 2. It is understood that the bottom surface of the paving box 6 gradually approaches the ground in a direction away from the vehicle 1, so that when the vehicle 1 moves, the inclined bottom surface can serve as a guide, gradually compacting the subsequent material and making paving smoother.

[0043] According to one embodiment of the present invention, the paving assembly further includes an auger 9, one end of which is rotatably connected to the first mounting plate 7 and the other end of which is rotatably connected to the second mounting plate 8. The auger 9 is spaced apart from the paving box 6. The auger 9 can be driven to rotate and has spiral blades on its surface. When the material to be paved, transported by the vehicle 1, is spread, the auger 9 can rotate to transport the material to be paved to both sides, thereby improving paving uniformity.

[0044] According to one embodiment of the present invention, the spiral distributor 9 is located on the side of the paving box 6 facing the chassis 2. That is, after the spiral distributor 9 spreads the material to be paved by rotation, the paving box 6 compacts it and spreads it more evenly.

[0045] According to one embodiment of the present invention, the paving assembly further includes a mounting box 10, which is mounted on top of the paving box 6. The drive rod assembly is rotatably connected to the mounting box 10, and the connecting rod assembly is rotatably connected to the paving box 6. The mounting box 10 helps to securely connect the drive rod assembly to the paving box 6, and the mounting box 10 can also provide a certain counterweight to increase the compaction strength of the paving assembly, thereby improving the paving effect.

[0046] According to one embodiment of the present invention, the connecting rod assembly includes at least two connecting rods 4, each of which rotatably connects the chassis 2 and the paving assembly. For example, the two connecting rods 4 are connected to either side of the paving assembly to ensure a stable connection and even force distribution, preventing the paving assembly from loosening.

[0047] According to one embodiment of the present invention, the drive rod assembly includes at least two drive rods 5, each of which is rotatably connected to the chassis 2 and the paving assembly. For example, the two drive rods 5 are connected to either side of the paving assembly, respectively. This effectively drives the paving assembly downward, increasing downward pressure and ensuring uniform force on both sides of the paving assembly.

[0048] According to one embodiment of the present invention, the driving rod 5 is a hydraulic rod, which has a simple structure, extremely high precision and control ability, can accurately control the linear movement and speed of the mechanism, and works efficiently and stably, while maintaining a certain pressure to compact the road surface, with good control accuracy.

[0049] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
