Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to an asphalt paving and compaction device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. To ensure smoothness, asphalt pavement requires leveling equipment after construction.

[0003] For example, announcement number CN221645483U, entitled "An Asphalt Pavement Construction Compaction Equipment", includes a main body, a pressure roller, a water tank, a support, and a collection box. The water tank is placed on top of the main body, and the support is placed in front of the main body. The pressure roller is placed on the support, and the collection box is connected and fixed to the support through a connecting rod. The material drop box is tangentially connected to the pressure roller. The material drop box, which is tangential to the pressure roller, collects the asphalt material adhering to the pressure roller. The collected asphalt material is automatically packaged and collected through the cooperation of the placement plate, the extrusion plate, and the material drop plate. The compressed material also saves more space. The water tank and the nozzle spray water to cool the pressure roller to prevent the asphalt material from adhering to the pressure roller, and also reduces the stickiness of the adhered material, making it easier to collect and process.

[0004] The existing compaction equipment mentioned above uses water spraying to treat the asphalt material on the rollers. This method wastes a lot of water resources, is costly, and has limited capacity for collection boxes and water tanks. During the compaction process, it is also necessary to stop for cleaning and replacement, which is inconvenient to operate. Therefore, it does not meet the current needs. In response, an asphalt paving and compaction equipment is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an asphalt paving and compaction device to solve the problems mentioned in the background art, which are that the existing compaction equipment uses water spraying to treat the asphalt material on the roller, which wastes a lot of water resources, has high cost, and has limited capacity of collection box and water tank. During the compaction process, it is also necessary to stop to clean and replace the water, which is inconvenient to operate.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an asphalt paving and compaction device, comprising: a frame, a pressure roller assembly, a scraping assembly, a fixing assembly, and a secondary compaction assembly. An adjustable-width pressure roller assembly is installed at the front end of the frame. A fixing assembly for limiting and fixing the pressure roller assembly is installed on the frame. A scraping assembly for scraping asphalt material is installed between the pressure roller assembly and the frame. A secondary compaction assembly for performing secondary compaction is installed at the middle position of the frame.

[0007] Preferably, the repressing assembly includes a lifting frame installed in the frame cavity, and multiple sets of repressing rollers arranged at intervals in front and behind are installed below the lifting frame. Both ends of the repressing rollers are equipped with extension frames for assembly with the lifting frame.

[0008] Preferably, the inner wall of the frame cavity is provided with multiple limiting grooves, and a displacement slider is installed in the limiting groove. The displacement slider is installed on both sides of the lifting frame, and an electric telescopic rod is installed above the lifting frame.

[0009] Preferably, the scraping assembly includes a mounting plate bolted to the end wall of the vehicle frame, and a plurality of scraping blocks are provided on the outer wall of the mounting plate.

[0010] Preferably, the front end of the vehicle frame is provided with assembly adjustment slots on both sides, an assembly adjustment frame is installed in the assembly adjustment slot, and several through holes are provided on the outer wall of the assembly adjustment frame and the assembly adjustment slot. An assembly frame is installed at the end of the assembly adjustment frame, and a pressure roller body is installed between the assembly frames.

[0011] Preferably, an assembly opening is provided above the assembly adjustment groove, a screw is installed in the through hole, and a rotating handle is installed at the upper end of the screw.

[0012] Preferably, two sets of rear wheels are installed at the rear end of the frame, and a handle is installed on the outer wall of the frame near the rear end.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, the scraping component is located between the pressure roller assembly and the frame. When the pressure roller assembly compacts the asphalt, some asphalt material will adhere to the pressure roller. During the rolling process, the adhered surface will rotate to the scraping component, causing the scraping block to contact the surface of the pressure roller. Combined with the rotational force, the asphalt material adhering to the surface of the pressure roller falls off. Then, the fallen asphalt material is compacted by the subsequent re-pressure roller. This allows for secondary compaction of the asphalt pavement while simultaneously compacting the fallen asphalt. Multiple sets of re-pressure rollers are arranged in a front-to-back configuration, allowing the secondary compaction process to be repeated multiple times, effectively improving the compaction effect of the asphalt pavement. The lifting frame can also be raised and lowered at this location via an electric telescopic rod to adjust the position of the re-pressure roller. When not in use, the re-pressure roller can be moved into the cavity for placement. This solves the problem of existing compaction equipment using water spraying to treat the asphalt material on the pressure roller, which wastes a lot of water resources, is costly, and has limited capacity in the collection box and water tank. Furthermore, it requires stopping for cleaning and replacement during the compaction process, making operation inconvenient.

[0015] (2) In this utility model, the main body of the pressure roller is installed between two assembly frames. The assembly adjustment frame can slide and move in the assembly adjustment groove. The exposed length of the assembly adjustment frame is changed by the displacement, thereby changing the distance between the two assembly frames. This allows users to install different specifications of pressure roller bodies according to the road width. After adjusting to the required length, the screw is driven downward by the handle, so that the screw passes through the through hole, restricting and fixing the assembly adjustment frame, and improving the stability of the compacted area.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4This utility model provides an embodiment of an asphalt paving and compaction device, comprising: a frame 1, a pressure roller assembly 2, a scraping assembly 3, a fixing assembly 4, and a secondary compaction assembly 5. Two sets of rear wheels 101 are installed at the rear end of the frame 1. A handle 102 is installed on the outer wall of the frame 1 near the rear end. The handle 102 and the rear wheels 101 allow the user to push the frame 1 to roll the pressure roller at the front, compacting the asphalt pavement. An adjustable-width pressure roller assembly 2 is installed at the front end of the frame 1. A fixing assembly 4 is installed on the frame 1 to limit and fix the pressure roller assembly 2. A scraping assembly 3 for scraping asphalt material is installed between the pressure roller assembly 2 and the frame 1. The scraping assembly 3 includes an assembly plate 301 bolted to the end wall of the frame 1. Several scraping blocks 302 are provided on the outer wall of the assembly plate 301. A secondary compaction assembly 5 for secondary compaction is installed at the middle position of the frame 1. The system includes a lifting frame 504 installed inside the cavity of the frame 1. Multiple sets of interlocking pressure rollers 506 are installed below the lifting frame 504. Both ends of the interlocking pressure rollers 506 are equipped with extension frames 505 for assembly with the lifting frame 504. Multiple limiting grooves 502 are provided on the inner wall of the cavity of the frame 1. Displacement sliders 503 are installed in the limiting grooves 502. The displacement sliders 503 are installed on both sides of the lifting frame 504. An electric telescopic rod 501 is installed above the lifting frame 504.

[0023] The scraping assembly 3 is located between the pressure roller assembly 2 and the frame 1. When the pressure roller assembly 2 compacts the asphalt, some asphalt material adheres to the pressure roller. As the pressure roller rolls, this adhered surface rotates to the scraping assembly 3, causing the scraping block 302 to contact the pressure roller surface. Combined with the rotational force, the asphalt material adhering to the pressure roller surface falls off. The subsequent secondary pressure roller 506 then compacts the fallen asphalt material, enabling secondary compaction of the asphalt pavement while simultaneously compacting the fallen asphalt. Multiple sets of secondary pressure rollers 506 are arranged in a staggered pattern, allowing this secondary compaction process to be repeated multiple times, effectively improving the compaction effect of the asphalt pavement. At this location, the lifting frame 504 can also be raised and lowered via an electric telescopic rod 501 to adjust the position of the secondary pressure roller 506. When not in use, the secondary pressure roller 506 can also be moved into the cavity for storage. During the lifting process, the setting of the limiting slide 502 and the displacement slider 503 can improve the lifting stability and limit the descent height.

[0024] Please see Figure 1 , Figure 2The front end of the frame 1 is provided with two sides of the assembly adjustment slot 201. The assembly adjustment slot 201 is installed in the assembly adjustment slot 202. The outer walls of the assembly adjustment slot 202 and the assembly adjustment slot 201 are provided with several through holes 203. The end of the assembly adjustment slot 202 is provided with an assembly frame 204. The pressure roller body 205 is installed between the assembly frames 204. The assembly opening 401 is provided above the assembly adjustment slot 201. The through hole 203 is provided with a screw 402. The upper end of the screw 402 is provided with a handle 403.

[0025] The pressure roller body 205 is installed between two assembly frames 204. It can slide within the assembly adjustment groove 201 via the assembly adjustment bracket 202. By changing the exposed length of the assembly adjustment bracket 202, the distance between the two assembly frames 204 can be changed. This allows users to install pressure roller bodies 205 of different specifications according to the road width. After adjusting to the required length, the screw 402 is driven downward by the handle 403, so that the screw 402 passes through the through hole 203, restricting and fixing the assembly adjustment bracket 202, thereby improving the stability of the compaction point. For subsequent adjustments, simply rotate the screw 402 upward to remove it, so that the assembly adjustment bracket 202 is no longer restricted, making it convenient for users to operate.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
