Description

Technical Field

[0001] The present invention relates to the technical field of asphalt cloth laying, and specifically to an asphalt cloth laying device for municipal engineering construction. Background Art

[0002] Municipal engineering construction is a key support for urban development, covering aspects such as roads, bridges, water supply and power supply facilities. Its purpose is to meet the basic needs of urban residents' daily life and social and economic operation, ensure the normal operation and sustainable development of the city, and has the characteristics of systematicness, public welfare and durability. It needs to be constructed by comprehensively considering factors such as urban planning, geographical environment and population distribution, providing public services such as convenient transportation, stable energy and good environment for citizens, and is of indispensable significance for enhancing the urban image, improving the quality of life, promoting economic prosperity and enhancing the city's ability to respond to disasters and emergencies.

[0003] Road construction in municipal engineering construction is of great importance. Roads form the traffic skeleton of the city, including different levels of main roads, secondary roads and branch roads. The technology of road construction is complex and delicate. It is necessary to design the roadbed according to different soil characteristics, and then lay stable and durable road surface materials. Asphalt is a commonly used road surface material. Asphalt pavement has a certain elasticity and can play a buffering role when vehicles drive on it. Compared with rigid pavements such as cement, asphalt pavement can better absorb the vibrations and noises generated by vehicle driving.

[0004] Before laying asphalt on the road, the base layer must be strictly treated to ensure it is flat, solid and dry, providing a stable foundation for the asphalt layer. Before laying, the asphalt heated to the appropriate temperature is evenly spread on the base layer, and then the pre-mixed asphalt mixture is spread on the road surface while it is still hot. Finally, a roller is used for multiple rolling until the specified compaction degree is reached, so that the asphalt mixture is closely combined to form a firm, flat, wear-resistant and elastic road surface layer, effectively bearing the vehicle load, ensuring the driving comfort and durability of the road, and providing high-quality traffic conditions for urban traffic. However, when the existing roller compacts asphalt, asphalt is easily adhered to the drum. When there is asphalt adhered to the drum, the contact between the drum and the road surface becomes uneven. In the area with asphalt adhesion, the pressure transmission will be hindered, resulting in insufficient compaction, while in other areas, over-compaction will occur due to relatively excessive pressure. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides an asphalt cloth laying device for municipal engineering construction, which solves the problem that when a roller compacts asphalt, asphalt is easily adhered to the roller. When asphalt adheres to the roller, the contact between the roller and the road surface becomes uneven. In the area with asphalt adhesion, the pressure transmission will be hindered, resulting in insufficient compaction, while in other areas, over-compaction will occur due to relatively excessive pressure.

[0014] Preferably, the housing is rotatably connected to the rotating shaft via a bearing, and the motor is fixedly connected to the housing via a fixing member.

[0015] An asphalt cloth laying device for municipal engineering construction comprises the following steps: S1, start hydraulic rod three and hydraulic rod four, so that hydraulic rod three pulls the lower end of the rotating plate, and hydraulic rod four pushes the lower end of the rotating plate on the other side of the rotating plate. The combined force of hydraulic rod three and the rotating plate causes the rotating plate to rotate around the fixed column, thereby lowering the roller to roll the asphalt pavement; S2, hydraulic rod 1 contracts, pulling the front end of the connecting plate down, so that the conversion mechanism in the shell is close to the surface of the drum, and then hydraulic rod 2 is extended, and hydraulic rod 2 pulls the middle part of connecting rod 1, so that the upper end of connecting rod 1 pulls connecting rod 2, and the lower end of connecting rod 2 pulls the top of the shell, so that the shell rotates around the connection point between the connecting plate and the shell, thereby adjusting the angle of the shell, so that the scraping mechanism in the shell fits the outer wall of the drum, and the attachments on the surface of the drum are cleaned; S3. Start the motor, which drives the shaft to rotate. Multiple scrapers fixedly connected to the motor surface rotate at high speed to scrape off the attachments on the drum surface. The long groove allows the scraper to move radially along the shaft. The spring and telescopic rod are set so that the scraper can always fit the surface of the drum, thereby effectively scraping off the attachments.

[0016] The present invention provides an asphalt cloth laying device for municipal engineering buildings. It has the following beneficial effects: 1. The present invention contracts hydraulic rod 1 to pull the front end of the connecting plate down, so that the scraping mechanism in the shell is close to the surface of the drum, and then extends hydraulic rod 2, which pulls the middle part of connecting rod 1, so that the upper end of connecting rod 1 pulls connecting rod 2, and the lower end of connecting rod 2 pulls the top of the shell, so that the shell rotates around the connection point between the connecting plate and the shell, thereby adjusting the angle of the shell, so that the scraping mechanism in the shell fits the outer wall of the drum, and the attachments on the surface of the drum are cleaned.

[0017] 2. In the present invention, when the road roller is being transferred, it will inevitably drive on normal roads. When the drum drives on normal roads, bumps will occur due to the uneven road surface, which will affect the stability of the road roller and cause damage to the normal road surface. At this time, the hydraulic rod three and the hydraulic rod four are activated, so that the hydraulic rod three pushes the lower end of the rotating plate, and the hydraulic rod four pulls the lower end of the rotating plate on the other side of the rotating plate. The combined force of the hydraulic rod three and the rotating plate causes the rotating plate to rotate around the fixed column, thereby lifting the drum provided at the lower end of the rotating plate and making the tires land, realizing the switch to the tires for driving on normal roads.

[0018] 3. In the present invention, when it is necessary to scrape the attachments on the surface of the drum, the motor is activated. The motor drives the rotating shaft to rotate, and multiple scrapers fixedly connected to the surface of the motor rotate at high speed to scrape the attachments on the surface. The long strip grooves enable the scrapers to move radially along the rotating shaft. The setting of the springs and the telescopic rods enables the scrapers to always fit the surface of the drum, well realizing the scraping of the attachments. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In the present invention, the protective cover 24 is fixed to the outer wall of the power cabin 12 to protect the power cabin 12 from various potential external risk factors. At the top of the protective cover 24, an alarm lamp 14 is fixedly connected, which can transmit danger signals to the surrounding area to ensure the safety of the vehicle and the surrounding personnel. The exhaust pipe 23 fixed to the top of the protective cover 24 timely discharges the high-temperature and harmful gases generated by combustion. On both sides of the outer wall of the cockpit 11, rearview mirrors 17 are symmetrically and fixedly connected, which can provide a wide and clear field of vision and effectively reduce the visual blind area. At the lower end of the cockpit 11, a plurality of pedals 25 are fixedly connected to facilitate the driver to enter the cockpit 11. The outer shell 10 is rotatably connected to the rotating shaft 301 through a bearing 19, enabling the scraping mechanism 3 to operate smoothly.

[0032] Working principle: When there are asphalt blocks attached to the surface of the drum 208, first, the first hydraulic rod 5 contracts, pulling the front end of the connecting plate 4 to fall, bringing the scraping mechanism 3 inside the housing 10 closer to the surface of the drum 208. Then, the second hydraulic rod 6 extends. The second hydraulic rod 6 pulls the middle part of the first connecting rod 7, causing the upper end of the first connecting rod 7 to pull the second connecting rod 8, and the lower end of the second connecting rod 8 to pull the top of the housing 10, making the housing 10 rotate around the connection point between the connecting plate 4 and the housing 10, thereby adjusting the angle of the housing 10 so that the scraping mechanism 3 inside the housing 10 fits the outer wall of the drum 208, realizing the cleaning of the attachments on the surface of the drum 208; When the road roller is being transferred, it will inevitably drive on normal roads. When the drum 208 drives on normal roads, it will jolt due to the uneven road surface, affecting the stability of the road roller and causing damage to the normal road surface. At this time, the third hydraulic rod 203 and the fourth hydraulic rod 205 are activated. The third hydraulic rod 203 pushes the lower end of the rotating plate 204, and the fourth hydraulic rod 205 pulls the lower end of the rotating plate 204 on the other side of the rotating plate 204. The third hydraulic rod 203 and the rotating plate 204 act together to make the rotating plate 204 rotate around the fixed column 206, thereby lifting the drum 208 provided at the lower end of the rotating plate 204 and making the tire 13 land on the ground, realizing the switch to the tire 13 for driving on normal roads; When it is necessary to scrape the attachments on the surface of the drum 208, the motor 307 is started. The motor 307 drives the rotating shaft 301 to rotate, and multiple scrapers 306 fixedly connected to the surface of the motor 307 rotate at high speed to scrape the attachments on the surface of the drum 208. The long slot 308 enables the scraper 306 to move radially along the rotating shaft 301. The settings of the spring 303 and the telescopic rod 302 enable the scraper 306 to always fit the surface of the drum 208, well realizing the scraping of the attachments.
