Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement treatment technology, specifically to an asphalt pavement micro-surfacing vehicle. Background Technology

[0002] Asphalt concrete pavement has become the main form of highway structure. With the increase in traffic density and vehicle load, pavement damage such as cracks, potholes, and ruts is inevitable. In order to prevent rainwater from seeping into and damaging the roadbed, micro-surfacing technology is required to carry out preventive maintenance on the pavement.

[0003] Currently, micro-surface treatment technology typically employs asphalt pavement micro-surfacing vehicles to lay a thin layer of mixture on the road surface to improve pavement performance. For example, patent application number 202311768565.X discloses an asphalt pavement fine surface treatment device and process, including a tractor body. The tractor body includes a frame, on which a refining component, a maintenance component, and a microwave heating component are mounted. A monitoring room is located at the front of the frame, and the side of the monitoring room near the rear of the monitoring room is connected to a grinding box. The grinding box is located away from the... One end of the monitoring room is connected to the maintenance box. The microwave heating component and the pressure roller assembly are both located at the bottom of the vehicle frame. The discharge guide hopper and the cloth distribution component are both located inside the vehicle frame. Preventive maintenance of the asphalt surface is carried out by making a fine surface treatment. After grinding and finening with a fine component, epoxy emulsified asphalt and silicon carbide aggregate are sprayed on the road surface to improve the adhesion and spraying effect. After spraying, an ultra-thin, wear-resistant protective layer will be formed on the asphalt pavement surface. The fine surface treatment can improve the performance of the asphalt pavement without reducing the anti-skid performance of the original pavement.

[0004] However, when using spraying to apply a protective layer to the road surface, it is difficult to control the thickness of the protective layer. This results in a height difference between the protective layer applied to potholes and the protective layer applied to smooth areas, thus affecting the quality of asphalt pavement maintenance. Therefore, we need to propose an asphalt pavement micro-surfacing vehicle to solve the above-mentioned problems, enabling it to effectively control the thickness of the protective layer and improve the quality of asphalt pavement maintenance.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: an asphalt pavement micro-surfacing vehicle, including a tractor 1, a mixing tank 2 for mixing paving materials is installed on the upper surface of the tractor 1, the lower end of the mixing tank 2 is connected to a storage tank 11 with heat preservation function, a discharge mechanism is inclinedly arranged on one side of the storage tank 11, the storage tank 11 is installed on the lower surface of the tractor 1, a leveling mechanism for scraping the paving materials is arranged on one side of the storage tank 11, the leveling mechanism is installed below the tractor 1 through a distance adjustment mechanism 9, an infrared distance sensor 16 for monitoring the distance between the leveling mechanism and the ground is installed on the leveling mechanism, an installation cavity 17 for installing the distance adjustment mechanism 9 is opened in the body of the tractor 1, and a microwave heating component 10 for preheating the asphalt pavement is arranged on the other side of the storage tank 11.

[0026] With the cooperation of the material discharge mechanism, leveling mechanism, distance adjustment mechanism 9 and infrared distance sensor 16, the distance between the leveling mechanism and the ground is monitored in real time by the infrared distance sensor 16. This allows the speed of the tractor 1 to be controlled according to the monitored distance, so as to fill the potholes and level them. At the same time, the distance between the leveling mechanism and the ground can be adjusted according to different asphalt pavement treatment needs to control the thickness of the protective layer, which improves the quality of asphalt pavement maintenance to a certain extent.

[0027] like Figure 2 and Figure 4As shown, the microwave heating component 10 can preheat the asphalt pavement to be laid protective layer, thereby improving the bonding strength between the protective layer and the asphalt pavement. The structure of the microwave heating component is a well-known technology in the field, such as the microwave heating component disclosed in the fine surface treatment device and process for asphalt pavement disclosed in application number 202311768565.X, which will not be described in detail here.

[0028] The leveling mechanism includes a scraper 8 and a leveling roller 5. The installation direction of the scraper 8 is parallel to the installation direction of the leveling roller 5. The two ends of the scraper 8 are connected to one end of the distance adjustment mechanism 9 through a first connecting rod 93. The two ends of the leveling roller 5 are connected to the other end of the distance adjustment mechanism 9 through a second connecting rod 94. The infrared distance sensor 16 is located at the lower end of one of the first connecting rods 93.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, by setting up the scraper 8 and the leveling roller 5, the raw material to be paved flows out from the discharge mechanism, and the scraper 8 first scrapes the raw material flat, and then the leveling roller 5 compacts the flattened raw material to improve the smoothness of the asphalt pavement.

[0030] The scraper 8 is an L-shaped structure composed of an inclined plate and a flat plate. The lower surface of the scraper 8 is flush with the lower surface of the leveling roller 5. The two ends of the leveling roller 5 are fixed with connecting shafts. The outer wall of the connecting shaft is fitted with a bearing, which is embedded in the second connecting rod 94.

[0031] like Figure 2 As shown, the scraper 8 is used to scrape the outflowing raw material with an inclined plate, and then the flat plate is used to smooth the scraped raw material. Through the cooperation of the connecting shaft and the second connecting rod 94, the leveling roller 5 can rotate with the movement of the tractor 1 to compact the spread raw material.

[0032] The distance adjustment mechanism 9 includes a support plate 91 that is slidably installed in the mounting cavity 17. A first connecting rod 93 and a second connecting rod 94 are respectively installed at the four corners of the support plate 91. Two threaded rods 92 are threadedly connected to the support plate 91. The two threaded rods 92 are driven by a drive mechanism, and the two ends of the threaded rods 92 are rotatably connected to the inner wall of the mounting cavity 17.

[0033] like Figure 2 and Figure 4As shown, the drive mechanism drives two threaded rods 92 to rotate. The threaded engagement between the threaded rods 92 and the support plate 91 adjusts the position of the support plate 91 on the threaded rods 92. This, in turn, drives the scraper 8 and the leveling roller 5 to move up or down via the support plate 91, adjusting the distance between the scraper 8 and the ground. This facilitates control over the thickness of the protective layer and improves the maintenance quality of asphalt pavement to a certain extent. The drive mechanism mainly consists of two sprockets 95 fixed to the upper ends of the threaded rods 92 and a second motor 96 installed on the upper end of one of the threaded rods 92. The two sprockets 95 are connected by a transmission chain, which allows the second motor 96 to drive one threaded rod 92 to rotate synchronously by driving the other threaded rod 92.

[0034] The discharge mechanism includes a discharge plate 12 that is inclined to one side of the lower end of the storage box 11 and is shaped like an opening. A baffle roller 13 is rotatably installed inside the discharge plate 12. The baffle roller 13 has a discharge hole 14. One end of the baffle roller 13 is driven by a first motor 15.

[0035] like Figure 3 and Figure 6 As shown, through the cooperation of the first motor 15 and the baffle roller 13, the baffle roller 13 can be rotated by the drive of the first motor 15. When the discharge hole 14 is connected to the inside of the storage box 11, the raw material in the storage box 11 flows out through the discharge hole. When the discharge hole 14 is in contact with the inner wall of the discharge plate 12, the baffle roller 13 blocks the discharge hole of the storage box 11, and the raw material is blocked inside the storage box 11. In addition, the overlapping area of ​​the discharge hole 14 and the inside of the storage box 11 can be controlled to control the flow rate of the raw material in the storage box 11 and improve the flexibility of raw material discharge.

[0036] The storage bin 11 has a trapezoidal cross-section. The two ends of the storage bin 11 are fixed with first baffles 6, and the lower end of the storage bin 11 is fixed with a second baffle 7. The scraper 8 is located between the two first baffles 6. The two ends and side walls of the baffle roller 13 are respectively attached to the inner walls of the discharge plate 12. The two ends of the baffle roller 13 are rotatably connected to the inner wall of the discharge plate 12 through a rotating shaft.

[0037] like Figures 2 to 4 As shown, the first baffle 6 and the second baffle 7 work together to block the outer periphery of the discharge plate 12, thereby controlling the range of the raw material after it flows out of the storage box 11, so that the flowing raw material can be scraped flat by the scraper 8, reducing the waste of raw material. The baffle roller 13 is set to be stable with the discharge plate 12, thereby controlling the flow or storage of raw material in the storage box 11.

[0038] The upper end of the mixing tank 2 is provided with a funnel-shaped feed hopper 3, the inside of the mixing tank 2 is equipped with a stirring mechanism 4, and the bottom of the mixing tank 2 is provided with an inclined surface. The lower end of the mixing tank 2 is connected to multiple discharge pipes 43 equipped with solenoid valves, and the discharge pipes 43 are located inside the storage tank 11.

[0039] like Figure 2 As shown, the inclined surface facilitates the collection of raw materials in the mixing tank 2 into the downward feed pipe 43, so as to transfer the raw materials in the mixing tank 2 into the storage tank 11. A heating coil is installed inside the side wall of the storage tank 11, and one end of the heating coil is connected to a temperature controller to keep the storage tank 11 warm and reduce the condensation of raw materials inside the storage tank 11.

[0040] The mixing mechanism 4 includes a mixing shaft 41 rotatably installed inside the mixing box 2. Multiple sets of mixing rods 42 are provided on the outer wall of the mixing shaft 41, and a mixing motor 44 is installed at one end of the mixing shaft 41.

[0041] like Figure 2 As shown, the stirring shaft 41 and the stirring motor 44 work together to make the stirring motor 44 drive the stirring shaft 41 to rotate. The stirring shaft 41 drives the stirring to move in a circular motion inside the mixing box 2, so as to mix the raw materials inside the mixing box 2 and improve the uniformity of the raw material processing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
