Description

Technical Field

[0001] The invention relates to the technical field of highway repair, in particular to a compaction system for highway pavement construction. Background Art

[0002] Highway pavement construction is the core link in transportation infrastructure construction, which is directly related to the quality of road traffic and its service life. As an important link connecting urban and rural areas and connecting regions, highway pavement needs to withstand multiple tests of vehicle loads, climate change and geological conditions. The construction process covers multiple steps such as roadbed treatment, material preparation, paving and compaction, involving the scientific proportion and process application of various materials such as asphalt concrete and cement-stabilized gravel. With the advancement of technology, modern pavement construction pays more attention to intelligence and greenness.

[0003] Patent application with application number CN202211251178.4 discloses a rapid pavement compaction device for highway construction, including a base plate, the bottom of which is rotatably connected to a roller, a feeding assembly is arranged on the base plate, the feeding assembly is used to add asphalt into potholes, a pressure plate is arranged on the side of the feeding assembly, the pressure plate is provided with a first drive assembly, the first drive assembly is used to drive the pressure plate to move downward to compact the asphalt; two scrapers are arranged symmetrically about the pressure plate below the pressure plate, and a second drive assembly is arranged on the scraper, and the second drive assembly drives the scraper to scrape off excess asphalt when the first drive assembly drives the pressure plate to compact the asphalt and move upward.

[0004] To sum up, during the asphalt compaction stage of highway construction, the roller used to squeeze asphalt may deviate sideways due to uneven asphalt laying thickness. Once the roller deviates sideways, it is difficult to flatten the road surface, affecting the construction quality. In addition, when scraping off excess asphalt, if too much is scraped off, the asphalt filling area may become dented during the subsequent use of the highway, reducing the service life of the highway.

[0016] Compared with the prior art, the present invention provides a compaction system for highway pavement construction, which has the following beneficial effects:

[0017] 1. The present invention provides a compaction system for highway pavement construction. During the highway construction process, the excess asphalt scraped off by the scraper will be transported to a collection box through a conveyor belt for unified collection and processing. The auxiliary roller will perform secondary rolling operations on the area where asphalt has been laid on the highway pavement, thereby further improving the flatness of the highway pavement.

[0018] 2. The present invention sets a support mechanism. When the asphalt pavement is extruded during highway construction, the first hydraulic rod pushes the first sliding block toward the highway pavement with the help of the first rotating rod. During this process, the second spring can effectively reduce shock and buffer the impact force generated during the pushing process to ensure that the entire operation process is carried out smoothly. At the same time, the first motor drives the extrusion roller to roll and perform extrusion operations on the asphalt pavement, thereby ensuring the pavement compaction effect.

[0019] 3. The present invention sets an adjustment component. During highway construction, the extrusion roller performs an extrusion operation on the asphalt filled on the road surface. When it is necessary to increase the pressure on the extrusion roller, the first hydraulic rod pushes the first connecting block, and the first connecting block drives the first sliding block through the first rotating rod to slide along the outer surface of the first fixed axis, thereby assisting in pushing the extrusion roller to more effectively extrude the asphalt area. When the extrusion roller encounters an asphalt area with inconsistent height, the first hydraulic rod will synchronously contract or push the first connecting block to ensure that the pressure of the extrusion roller remains consistent when extruding various asphalt areas, thereby effectively avoiding the lateral deviation of the extrusion roller due to uneven asphalt laying thickness.

[0020] 4. The present invention sets an auxiliary mechanism. During the highway construction process, when the second hydraulic rod pulls the second connecting block to move in the direction of the first auxiliary roller, the second connecting block pushes the second sliding block to slide along the outer surface of the second fixed shaft with the help of the second rotating rod. The second sliding block squeezes the elastic component on the one hand, and drives the third auxiliary roller to slide on the other hand, thereby stretching the excess part of the conveyor belt, ensuring that the conveyor belt is always in a taut state, providing a strong guarantee for the smooth transportation of excess asphalt.
