Description

Technical Field

[0001] The invention relates to the technical field of asphalt pavement repair, and in particular to a planing device for repairing petroleum asphalt pavement. Background Art

[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials. The asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. The asphalt structural layer of asphalt pavement itself belongs to the category of flexible pavement, but in addition to flexible materials, its base layer can also use rigid cement concrete or semi-rigid hydraulic materials.

[0003] In the prior art, the old asphalt pavement needs to be broken before repair, mainly because repairing directly on the aged asphalt layer often fails to achieve the expected repair effect. If the repair is directly on the old asphalt pavement, there may be a misalignment between the new and old pavements, resulting in water accumulation and moisture infiltration into the interface between asphalt and aggregate, affecting adhesion, and ultimately causing the pavement to become loose and damaged. At the same time, after long-term use and environmental influences, the asphalt of the old asphalt pavement will gradually age, the adhesion will decrease, and the brittleness will increase. If the aged asphalt layer is not broken, it will be difficult for the newly laid asphalt layer to form an effective bond with it, thereby affecting the repair effect. Therefore, when repairing petroleum asphalt pavement, the old asphalt needs to be planed off, and asphaltene is an important component of asphalt. As time goes by, asphaltene will agglomerate, making the overall structure of asphalt tighter. At the same time, the components of the laid asphalt in the asphalt undergo oxidation and polymerization reactions under the action of oxygen to form a larger molecular structure, which increases the hardness of the asphalt. In addition, the physical properties of asphalt are greatly affected by temperature. Under different weather conditions, the asphalt will be too hard or too viscous, making it difficult to effectively plane, thereby increasing the difficulty of planing. Summary of the invention

[0038] Working principle: Please refer to Figure 1-Figure 8 As shown, by setting the gravel column 19, when the staff repairs the old petroleum asphalt pavement, by using the servo motor 5, the rotation of the drive shaft of the servo motor 5 will drive the input shaft of the double-axis turbine worm reducer 6 to rotate, and then the rotation of the input shaft of the double-axis turbine worm reducer 6 will cause the output shaft of the double-axis turbine worm reducer 6 to rotate, and when the output shaft of the double-axis turbine worm reducer 6 rotates, it will drive the transmission column 8 and the fixed column 9 to rotate and drive the rotating column 10, and then the fixed column 9 will drive the rotating column 10 to move in a circular motion, and during the movement of the rotating column 10, it will pull the pulling column 15 to move, because the pulling column 15 and the extension column 12 are connected by a connecting rod, when the pulling column 15 is driven to move by the rotating column 10 , the pulling column 15 will move up and down, and drive the installation column 18 and the crushed stone column 19 to move. At this time, the crushed stone column 19 will form a hammering action on the ground, and will be pulled back a distance under the continuous movement of the pulling column 15, so as to facilitate the crushing of the old petroleum asphalt pavement, so as to make the old asphalt detach from the road surface, so as to plane the asphalt pavement that needs to be repaired, and prevent direct repair on the old asphalt pavement. There may be a misalignment between the new and old pavements, resulting in water accumulation and moisture infiltration into the interface between asphalt and aggregate, affecting adhesion, and ultimately causing the road surface to become loose and damaged. At the same time, by hammering to plane the asphalt, it can be prevented that the potholes or cracks in the asphalt pavement that needs to be repaired are small in scope, and the old asphalt cannot be directly shoveled up from the bottom of the asphalt using a shovel.

[0039] By setting the planing plate 33, when the staff uses the crushed stone column 19 to break the old asphalt pavement, as the walking frame 1 moves, the broken position will gradually enter the bottom of the walking frame 1 and contact the planing plate 33, and then the movement of the walking frame 1 will drive the mounting frame 32 and the planing plate 33 to move, and the planing plate 33 will move close to the ground. When encountering an uneven road surface, the planing plate 33 will be squeezed by the road surface and will drive the mounting block 36, the contraction column 37 and the connecting plate 39 to move and compress the spring 38 to move, so as to adapt to the uneven asphalt road surface, thereby facilitating the planing of the asphalt crushed by the crushed stone column 19 and allowing the broken asphalt blocks to leave the road surface.

[0040] By means of the cleaning brush 45, when the scraping board 33 scrapes the asphalt on the road surface, the asphalt blocks will pass through the surface of the scraping board 33 after being scraped by the scraping board 33, and will approach the rotating wheel 44 as the traveling frame 1 moves. Then, the staff uses the driving motor 43, and the driving shaft of the driving motor 43 rotates to drive the rotating wheel 44 and the cleaning brush 45 to rotate, and then the cleaning brush 45 will sweep the asphalt blocks scraped on the road surface into the interior of the protective shell 46. Then, as the rotating wheel 44 and the cleaning brush 45 rotate, the asphalt blocks can be passed through the discharge hole 48 and the feed hole 49 to enter the interior of the collecting box 47 for collection, thereby facilitating the cleaning of the scraped asphalt blocks and debris, and preventing the scraped asphalt debris from accumulating and affecting the subsequent asphalt repair of the petroleum road surface.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
