Description
Technical Field
[0001] This utility model relates to the field of asphalt pavers, and in particular to an asphalt paving device for municipal road construction. Background Technology
[0002] In municipal road construction and maintenance projects, asphalt paving is one of the core construction processes, and asphalt paving equipment for municipal road construction (with asphalt pavers as the core equipment) is key to achieving efficient and uniform asphalt paving. These devices typically integrate functions such as asphalt conveying, distribution, screeding, and preliminary compaction. The asphalt paver conveys the molten asphalt mixture to the work surface, and then the distribution and screeding components evenly distribute and screed the asphalt material, ultimately forming an asphalt base or surface layer with a certain thickness and smoothness. Widely used in various municipal road construction scenarios such as urban arterial roads, secondary roads, and residential roads, these devices significantly improve the efficiency and quality stability of asphalt paving, making them an indispensable core piece of equipment in modern municipal road construction.
[0003] However, in actual construction, due to various factors such as the uniformity of the asphalt mixture, the stability of the paving speed, and the flatness of the base layer, asphalt pavement surfaces often exhibit defects such as localized potholes, depressions, or uneven aggregate distribution after the initial screeding operation. Traditional methods for addressing these issues primarily rely on manual repair: workers use shovels, scrapers, and other tools to scoop asphalt from the paver's asphalt storage bins or separate asphalt transfer equipment, following closely behind the paver to manually fill and initially level the defective areas, followed by secondary compaction by a subsequent roller. This method is cumbersome, inefficient, and the repair speed is difficult to match with the paver's paving speed, leading to delayed repairs. Furthermore, the density and flatness of the manually filled asphalt are difficult to maintain with the overall paver-paved surface, affecting road construction quality. Additionally, workers following the paver pose certain safety hazards. Utility Model Content
[0004] The main objective of this invention is to provide an asphalt paving device for municipal road construction, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An asphalt paving device for municipal road construction includes an asphalt paver body. A material distribution and screeding assembly is fixedly installed at the rear of the asphalt paver body. A clamping bracket is fixedly installed at the rear of the material distribution and screeding assembly. The clamping bracket consists of guide rails, support arms, and rollers. Two guide rails and two support arms are provided. The two support arms are symmetrically fixed at the left and right ends of the guide rails. The rollers are rotatably mounted at the rear of the two support arms. A movable repair assembly is slidably installed between the two guide rails. The movable repair assembly consists of a hopper, sliders, a square rod, a baffle, a spring, a sealing plate, an L-shaped connecting arm, and a block. There are two sliders, which are symmetrically fixedly installed at the front and rear ends of the hopper. The square rod is fixedly installed at the front end of the hopper. The baffle is fixedly installed at the front end of the square rod. The spring is sleeved on the square rod. The sealing plate is movably installed at the lower end of the hopper. The L-shaped connecting arm is fixedly installed at the front end of the sealing plate. The block is fixedly installed at the upper end of the L-shaped connecting arm and is simultaneously slidably installed on the square rod. The block is located behind the spring.
[0006] Preferably, a standing platform is fixedly installed at the rear of the material dispensing and ironing assembly.
[0007] Preferably, the support arm on the clamping bracket is fixedly installed at the rear end of the material distribution and ironing assembly by bolts, and the two support arms are respectively located on the left and right sides of the standing platform.
[0008] Preferably, the guide rail plate on the clamping bracket has a guide rail groove, and the guide rail plate is fixedly connected to the support arm by bolts.
[0009] Preferably, the hopper on the movable repair assembly is slidably mounted between two guide rail plates, and the slider is slidably mounted in a guide rail groove opened on the guide rail plate.
[0010] Preferably, the block on the movable repair component has a square hole, and the block is slidably mounted on the square rod through the square hole, with the square rod located below the guide rail plate.
[0011] Compared with the prior art, the present invention has the following beneficial effects: A pressing bracket consisting of a guide rail, support arm, and roller is installed at the rear of the material distribution and screeding assembly. A movable repair component consisting of a hopper, slider, square rod, baffle, spring, sealing plate, L-shaped connecting arm, and block is mounted on the pressing bracket. Asphalt material can be pre-filled into the hopper. After the asphalt paver completes the initial asphalt paving via the material distribution and screeding assembly, if potholes or depressions appear on the road surface, the workers move the movable repair component along the guide rail to the defect location. Then, the block is pulled forward, sliding through the square hole on the square rod and compressing the spring. Simultaneously, the block is moved forward by the L-shaped connecting arm. The asphalt material is then moved forward, opening the lower end of the hopper and allowing the pre-stored asphalt to fall into the pothole. After filling, the block is released, and the spring returns to its original position, pushing the block backward. This, in turn, causes the L-shaped connecting arm to reset and close the lower end of the hopper. As the entire device moves, the rollers on the clamping bracket compact the filled asphalt material. This eliminates the need for manual refilling from the storage bin and waiting for subsequent compaction by the road roller, effectively improving the efficiency of road defect repair and ensuring the consistency of density and smoothness between the repaired area and the overall road surface. It also reduces the safety hazards for construction workers following the paver. Attached Figure Description

Detailed Implementation
[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0015] Please see Figure 1 , Figure 2 , Figure 3As shown, an asphalt paving device for municipal road construction includes an asphalt paver body 1. A material distribution and screeding assembly 2 is fixedly installed at the tail of the asphalt paver body 1. A clamping bracket 3 is fixedly installed at the tail of the material distribution and screeding assembly 2. The clamping bracket 3 consists of a guide rail plate 6, support arms 8, and a roller 9. There are two guide rail plates 6 and two support arms 8. The two support arms 8 are symmetrically fixed at the left and right ends of the guide rail plate 6. The roller 9 is rotatably installed at the tail of the two support arms 8. A movable repair assembly 4 is slidably installed between the two guide rail plates 6. The movable repair assembly 4 consists of a hopper 10, a slider 11, a square rod 12, a baffle 13, and a spring 14. The hopper 10 is composed of a sealing plate 15, an L-shaped connecting arm 16, and a block 17. Two sliders 11 are symmetrically fixedly installed at the front and rear ends of the hopper 10. A square rod 12 is fixedly installed at the front end of the hopper 10. A baffle 13 is fixedly installed at the front end of the square rod 12. A spring 14 is sleeved on the square rod 12. The sealing plate 15 is movably installed at the lower end of the hopper 10. The L-shaped connecting arm 16 is fixedly installed at the front end of the sealing plate 15. The block 17 is fixedly installed at the upper end of the L-shaped connecting arm 16 and simultaneously slides on the square rod 12. The block 17 is located behind the spring 14. The material distribution and ironing assembly 2 is further supported by a guide rail plate 6, a support arm 8, and a rolling roller 9. The clamping bracket 3 is equipped with a movable repair component 4 consisting of a hopper 10, a slider 11, a square rod 12, a baffle 13, a spring 14, a sealing plate 15, an L-shaped connecting arm 16, and a block 17. Asphalt material can be pre-filled into the hopper 10. After the asphalt paver body 1 completes the initial asphalt paving via the material distribution and smoothing component 2, if potholes or depressions appear on the road surface, the construction personnel move the movable repair component 4 along the guide rail 6 to the defect location. Then, they pull the block 17 forward. The block 17 slides on the square rod 12 through the square hole 18 and compresses the spring 14. Simultaneously, the block 17 drives the sealing plate 17 via the L-shaped connecting arm 16. 5. Move forward to open the lower opening of the hopper 10, and the pre-stored asphalt material will fall into the road pothole. After filling, release the block 17, and the spring 14 will reset and push the block 17 to move backward. Then, through the L-shaped connecting arm 16, the sealing plate 15 will reset and close the lower opening of the hopper 10. Afterward, as the whole device moves, the roller 9 on the clamping bracket 3 can roll and compact the filled asphalt material. There is no need for manual additional material to be taken from the storage bin for filling and waiting for subsequent compaction by the road roller. This effectively improves the efficiency of road defect repair, ensures the consistency of the density and smoothness of the repaired area with the overall road surface, and reduces the safety hazards of construction personnel following the paver.
[0016] Specifically, a standing platform 5 is fixedly installed at the rear of the material distribution and ironing assembly 2. The support arm 8 on the clamping bracket 3 is fixedly installed at the rear end of the material distribution and ironing assembly 2 by bolts, and the two support arms 8 are located on the left and right sides of the standing platform 5 respectively. The guide rail plate 6 on the clamping bracket 3 has a guide rail groove 7. The guide rail plate 6 and the support arm 8 are fixedly connected by bolts. The hopper 10 on the movable repair assembly 4 is slidably installed between the two guide rail plates 6. The slider 11 is slidably installed in the guide rail groove 7 on the guide rail plate 6. The block 17 on the movable repair assembly 4 has a square hole 18. The block 17 is slidably installed on the square rod 12 through the square hole 18. The square rod 12 is located on the guide rail plate. Below 6, when using this municipal road construction asphalt paving device, first start the asphalt paver body 1 and make it move according to the preset construction route. The asphalt paver body 1 will transport the asphalt mixture to the distribution and screeding component 2. The distribution and screeding component 2 will evenly distribute and initially screed the asphalt mixture. Construction personnel can stand on the standing platform 5 at the rear of the distribution and screeding component 2 to observe the road surface condition after paving. At the same time, an appropriate amount of asphalt repair material is pre-loaded into the hopper 10 of the movable repair component 4. When potholes, depressions or other defects are found on the road surface after being treated by the distribution and screeding component 2, the construction personnel will push the hopper 10 so that the hopper 10 passes through the front and rear ends. The slider 11 slides within the guide grooves 7 of the two guide plates 6 of the clamping bracket 3, moving the movable repair component 4 directly above the road defect. Then, the worker pulls the block 17 forward. The block 17 slides forward on the square rod 12 through its square hole 18, compressing the spring 14 sleeved on the square rod 12 and located between the block 17 and the baffle 13. Simultaneously, the block 17 drives the L-shaped connecting arm 16, which is fixedly connected to it, to move forward. The L-shaped connecting arm 16 then pulls the sealing plate 15 at the lower end of the hopper 10 forward, opening the lower opening of the hopper 10. The asphalt repair material pre-stored in the hopper 10 then falls into the road defect area. After the filler material is filled, the construction workers release the block 17. The compressed spring 14 returns to its original shape and pushes the block 17 to slide backward on the square rod 12. The block 17 drives the sealing plate 15 to reset backward through the L-shaped connecting arm 16, closing the lower opening of the hopper 10 again. Then, as the asphalt paver body 1 continues to move, the rollers 9 installed at the tails of the two support arms 8 of the clamping bracket 3 will move with the whole device and compact the asphalt repair material filling the road defect area, ensuring that the density and smoothness of the repair area are consistent with the overall road surface. The whole process does not require the construction workers to take material from the storage bin or wait for the subsequent road roller, effectively improving the repair efficiency and reducing safety hazards.
[0017] It should be noted that the width of the roller 9 is the same as the width of the material distribution and screeding component 2 to ensure that the area of the material distribution and screeding component 2 is fully rolled, and to ensure that the overall road surface compaction effect is consistent. At the same time, the asphalt material in the hopper 10 cannot be stored for a long time to prevent the asphalt material from cooling down and changing its properties due to prolonged storage, which would affect the repair quality. Therefore, fresh asphalt material needs to be replenished in a timely manner according to the construction progress.
[0018] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
