Description

Technical Field

[0001] The invention relates to the technical field of road surface leveling, and in particular to a road surface leveling device and a leveling method thereof for paving an asphalt road surface. Background Art

[0002] Asphalt pavement is the most widely used high-grade pavement in road construction. When laying asphalt pavement, the asphalt is laid on the road surface by a paving machine, and then it is flattened by the flattening roller on the flattening machine to make the asphalt laid on the road surface smooth.

[0003] When the flattening machine levels the asphalt pavement that has been paved, it is generally flattened directly by a flattening roller. There are generally more soil and gravel on both sides of the asphalt road. When the asphalt is paved, gravel will appear on the surface of the asphalt road due to various reasons. And because the newly paved asphalt pavement is still in a relatively soft state, the flattening roller will press the stones on the asphalt pavement into the interior of the asphalt pavement during the flattening work, thereby destroying the integrity of the asphalt pavement. After a long time, the stones stuck in the asphalt pavement will be broken, resulting in a large pit on the asphalt pavement, affecting the use of the asphalt pavement. Summary of the invention

[0013] A leveling method of a road surface leveling device for asphalt pavement paving, comprising the following steps: S1: When the pushing device is connected to the external frame and pushes the main body to move, the forward pushing force will drive the cleaning tripod to press downward, so that the cleaning tripod is close to the ground, and the cleaning tripod moves on the ground through the auxiliary wheels and the moving wheels following the movement of the main body, and the cleaning tripod pushes the debris to both sides of the cleaning tripod, so that the debris on the road ahead is moved to both sides of the device; S2: The main body drives the leveling wheel to roll at the bottom of the main body to flatten the asphalt road surface; S3: The motor drives the half gear to rotate, and the half gear drives the half tooth rotating shaft to rotate, thereby driving the winding rod to rotate, and the rotating frame drives the fitting spring and the elastic scraper to move on the outer wall of the cleaning tripod to scrape off the asphalt or debris stuck to the outer wall of the buffer spring; S4: By meshing with the connecting gear, the belt can be driven to roll on the connecting gear, thereby driving the two secondary pulleys on the connecting frame to rotate, driving the cleaning frame to roll, and the surface of the leveling wheel can be cleaned by the outer wall of the cleaning frame contacting the outer wall of the leveling wheel.

[0014] Compared with the prior art, the present invention provides a road surface leveling device and a leveling method for asphalt pavement paving, which have the following beneficial effects: 1. When the present invention pushes the main body to move by connecting the external pushing device with the external frame, the forward pushing force drives the cleaning tripod to press downward, so that the cleaning tripod is close to the ground, and thus follows the movement of the main body to make the cleaning tripod move on the ground through the auxiliary wheels and the moving wheels, and push the debris on the asphalt road surface in front forward, and through the triangular cleaning tripod, when the cleaning tripod contacts the debris on the road surface, the debris is pushed to the two sides of the cleaning tripod, so that the debris on the road surface in front moves to the two sides of the device, and when the main body drives the leveling wheel to perform the leveling work, it is avoided that the stones on the asphalt road surface are pressed into the interior of the asphalt road surface, so as to avoid damaging the integrity of the asphalt road surface, and to avoid that the stones stuck in the asphalt road surface will be broken after a long time, resulting in a large pit on the asphalt road surface, so as to avoid affecting the use of the asphalt road surface.

[0015] 2. When the cleaning tripod of the present invention is in close contact with the ground, the cleaning tripod drives the buffer frame on the top to slide inside the contraction hole, and squeezes the buffer spring, and cooperates with the telescopic rod and the elastic sleeve at the same time. The continuous force of the cleaning tripod is transmitted to the telescopic rod through the triangular extension frame, so that the telescopic rod is contracted and the elastic sleeve is compressed for buffering, thereby avoiding the phenomenon that the triangular extension frame is broken or damaged due to excessive downward pressure. When encountering a sloping road surface, the cleaning tripod and the moving wheels can be closely attached to the road surface through the rotation connection between the movable frame and the triangular extension frame, thereby avoiding the gap between the cleaning tripod and the ground and the inability to clean smaller stones to both sides of the main body, thereby improving the practicability of the device.

[0016] 3. The present invention drives the half gear to rotate through the motor, and drives the half-tooth rotating shaft to rotate through the half gear, thereby driving the winding rod to rotate, thereby driving the fitting spring sheet and the elastic scraper to move on the outer wall of the cleaning tripod through the rotating frame, and scraping off the asphalt or debris stuck to the outer wall of the buffer spring. When the elastic scraper moves with the shape of the cleaning tripod, it will drive the telescopic plate and the stretching spring to stretch and shrink inside the shrinkage groove, so that the fitting spring sheet and the elastic scraper can be tightly attached to the surface of the cleaning tripod through the tension of the stretching spring, and the debris on the outer wall of the cleaning tripod can be scraped off, thereby avoiding the difficulty of pushing the debris to both sides because the outer wall of the cleaning tripod is covered with debris.

[0017] 4. The present invention can drive the elastic scraper and the fitting spring to move from one end of the cleaning tripod to the other end during the rotation of the winding rod, and tighten the winding rod at the same time. When the elastic scraper and the fitting spring move to the other end, the half gear will be disengaged from the half-tooth rotating shaft, and the elastic force of the tightened winding spring will drive the winding rod to rotate in the opposite direction, thereby driving the elastic scraper and the fitting spring to reset through the rotating frame, and repeating this process. When the full gear continues to rotate, the full gear under the half gear can be driven to rotate, and the belt can be driven to roll on the connecting gear through the meshing with the connecting gear, thereby driving the two secondary pulleys on the connecting frame to rotate, and driving the cleaning frame to roll. The outer wall of the cleaning frame contacts the outer wall of the leveling wheel, so that the surface of the leveling wheel can be cleaned, thereby improving the practicability of the device.
