Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a semi-flexible composite pavement construction equipment. Background Technology

[0002] Semi-flexible pavement is a composite pavement that combines rigidity and flexibility, formed by compacting large-void asphalt mixture and then injecting high-flowability cement grout. In the construction of semi-flexible composite pavement, power trowels are mainly used in the surface treatment stage after the cement-based grout is injected, and the smoothness, density and wear resistance of the pavement are improved by smoothing and finishing operations.

[0003] A conveniently disassembled floor trowel is disclosed in Chinese Patent Publication No. CN222253003U. This conveniently disassembled floor trowel transmits the torque output by the power unit to the trowel blades through the transmission system. When the trowel blades come into contact with the surface of concrete or mortar that has not fully hardened, the rotating blades generate horizontal shearing force and vertical pressure on the surface material, thereby further compacting the surface material, expelling excess moisture and air, and improving the surface density and smoothness. However, according to the trowels provided in related fields and existing technologies, traditional trowels only compact materials by rotating the trowel disc or blades. If the material is left for a long time, has uneven moisture content, or has agglomerated additives, forming lumps, the trowel disc cannot break up the hardened structure, which easily leads to the lumps being directly compacted on the surface, forming local unevenness, bulges, or voids, affecting the smoothness and density of the road surface.

[0025] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0026] like Figures 1 to 8 As shown, a semi-flexible composite pavement construction device includes a mounting base 1. A troweling mechanism 2 is rotatably mounted on the bottom of the mounting base 1. A protective cover 3 is fixedly mounted on the outer surface of the mounting base 1 to cover the outside of the troweling mechanism 2. A handle 4 is fixedly mounted on the rear side of the top of the mounting base 1. A drive mechanism 5 for controlling the rotation of the troweling mechanism 2 is fixedly mounted on the top of the mounting base 1. The troweling mechanism 2 includes a troweling disc 21 and a cover plate 22 fixedly mounted on the top of the troweling disc 21. A connecting shaft 221 is fixedly mounted at the center of the top of the cover plate 22. The output end of the drive mechanism 5 is splinedly connected to the connecting shaft 221. Multiple loosening components 6 are longitudinally slidably arranged inside the troweling disc 21. A guide component 7 is fixedly mounted on the protective cover 3 at the position corresponding to the troweling disc 21. The guide component 7 is used to allow the loosening components 6 to extend when the troweling disc 21 rotates to the front side of the mounting base 1 and retract when it rotates to the rear side.

[0027] The loosening component 6 includes a fixing plate 61, a guide 62 is fixedly installed on the top of the fixing plate 61, and a plurality of toothed parts 63 are fixedly provided on the bottom of the fixing plate 61.

[0028] The guiding component 7 includes a first track 71 and a second track 72 fixedly installed inside the protective cover 3. The first track 71 and the second track 72 form a ring. Both ends of the first track 71 and the second track 72 are fixedly provided with connecting tracks 73. The connecting tracks 73 are provided with inclined surfaces 731 corresponding to the positions of the first track 71 and the second track 72. The height of the first track 71 is lower than that of the second track 72. The first track 71 is located on the front side of the mounting base 1, and the second track 72 is located on the rear side of the mounting base 1. When the loosening component 6 rotates with the smearing disc 21 to the front side of the guiding component 7, it automatically extends downwards to mechanically loosen the clumps of material, break up the hardened structure, and make the material particles more evenly distributed. When it rotates to the rear side of the guiding component 7, the loosening component 6 retracts and is flattened and compacted by the smearing disc 21 to avoid unevenness caused by clumps and improve the smoothness and density of the road surface.

[0029] The guide member 62 includes a guide rod 621 fixedly mounted on the top of the fixed plate 61. The guide rod 621 has an L-shaped cross-section. A support rod 622 is fixed between the guide rod 621 and the fixed plate 61. One end of the guide rod 621 away from the fixed plate 61 is inserted into the guide assembly 7. A ball bearing 623 is provided at the end of the guide rod 621 away from the fixed plate 61. A bearing 624 is rotatably mounted on the outer surface of the guide rod 621 near the ball bearing 623. The bearing 624 is adapted to the first track 71, the second track 72, and the connecting track 73. The polishing mechanism 2 is rotated by the drive mechanism 5. When the ball bearing 623 at the end of the guide rod 621 comes into contact with the sidewall of the first track 71, the second track 72, and the connecting track 73, the bearing 624 will roll inside the first track 71, the second track 72, and the connecting track 73. The toothed member 63 includes a thread fixedly mounted on the bottom of the fixed plate 61. The rod 631 has an inner threaded cylinder 632 threadedly connected to its outer surface. The bottom end of the inner threaded cylinder 632 is closed. The threaded connection between the inner threaded cylinder 632 and the rod 631 allows the length of the toothed component 63 to be adjusted according to requirements. This enables flexible adjustment of the loosening depth based on the thickness of the paved material (for example, for a thicker material layer, the tooth is lengthened to ensure deep loosening; for a thinner material layer, the tooth is shortened to avoid excessive damage to the base layer, thus expanding the applicability of the equipment). The squeegee disc 21 has movable grooves 211 at the positions of multiple guide rods 621, and through holes 212 at the positions of multiple inner threaded cylinders 632. The outer surface of the inner threaded cylinder 632 is in contact with the side wall of the through hole 212. When the inner threaded cylinder 632 retracts, the contact between the outer surface of the inner threaded cylinder 632 and the side wall of the through hole 212 automatically scrapes away impurities from the surface of the inner threaded cylinder 632.

[0030] The work process is as follows:

[0031] S1: As Figures 2 to 8 As shown, during use, the polishing mechanism 2 is rotated by the drive mechanism 5. Then, when the ball 623 at the end of the guide rod 621 comes into contact with the side wall of the first track 71, the second track 72 and the connecting track 73, the bearing 624 will roll inside the first track 71, the second track 72 and the connecting track 73.

[0032] S2: As Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the guide rod 621 enters the first track 71 through the connecting track 73, the height difference between the first track 71 and the second track 72 can be used to allow the guide rod 621 to control multiple toothed parts 63 to extend from the inside of the polishing disc 21 through the fixing plate 61.

[0033] S3: As Figures 5 to 8 As shown, when the guide rod 621 enters the second track 72 through the connecting track 73, the height difference between the first track 71 and the second track 72 can be used to allow the guide rod 621 to control multiple toothed parts 63 to retract into the polishing disc 21 through the fixing plate 61.

[0034] S4: In summary, when the loosening component 6 rotates with the trowel disc 21 to the front of the guide component 7, it automatically extends downwards to mechanically loosen the clumps of material, break up the hardened structure, and make the material particles more evenly distributed. When it rotates to the rear of the guide component 7, the loosening component 6 retracts and is leveled and compacted by the trowel disc 21 to avoid unevenness on the surface caused by clumping and improve the smoothness and density of the road surface.

[0035] S5: As Figure 7 As shown, the threaded connection between the inner threaded cylinder 632 and the threaded rod 631 allows the length of the toothed component 63 to be adjusted according to requirements, thereby enabling flexible adjustment of the loosening depth based on the thickness of the paved material.

[0036] The drive mechanism 5 described in this application is known in the art, therefore its specific structure and working principle are not described in detail.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
