Description

Technical Field

[0001] The utility model relates to the field of municipal road construction, in particular to a combined road repair device for asphalt pavement. Background Art

[0002] Asphalt pavement refers to the road surface paved with asphalt as the main material. Asphalt pavement is mainly composed of asphalt mixture, which usually includes asphalt glue and aggregate. Compared with concrete pavement, the construction speed of asphalt pavement is faster. At the same time, the maintenance of asphalt pavement is relatively simple, and local repairs and overlays can be carried out. Therefore, asphalt is generally used as a material for municipal road construction. When assisting asphalt construction, existing equipment will cooperate with rollers to achieve the overall flatness of the road surface. However, direct rolling operation makes it difficult to remove bubbles between materials. The presence of gaps between materials will reduce the service life of asphalt, and its waterproof performance and toughness will also be reduced.

DETAILED DESCRIPTION

[0018] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0019] Example 1

[0020] A combined road repair device for asphalt pavement, such as Figure 1 and Figure 2 As shown, it includes a first mounting plate 3, and dampers 4 are slidably connected to the front and rear parts of the first mounting plate 3, and shock-absorbing springs 5 ​​are connected between the damper 4 and the first mounting plate 3. A roller 2 is rotatably arranged between the damper 4, and a walking wheel 1 is rotatably arranged on the lower right side of the first mounting plate 3. A driving assembly 6 is connected between the upper front side of the first mounting plate 3 and the roller 2. The driving assembly 6 includes a driving motor, a pulley and a belt. A sprinkler assembly 7 is connected to the upper right side of the first mounting plate 3. The sprinkler assembly 7 includes a water tank, a water cover, a water pump and a water spray rack. A baffle plate 8 is connected to the left side of the first mounting plate 3, and the lower side of the baffle plate 8 is a structure inclined to the right. A scattering mechanism 9 for evenly scattering the asphalt material is arranged on the lower right side of the first mounting plate 3.

[0021] like Figure 1-Figure 3 As shown, the breaking mechanism 9 includes a hydraulic cylinder 94, and two hydraulic cylinders 94 are connected to the lower right side of the first mounting plate 3, which are symmetrical in front and back. The telescopic end of the hydraulic cylinder 94 on the rear side is connected to a mounting box 91, and a driving motor 92 is installed in the mounting box 91. The output shaft of the driving motor 92 is connected to an auger 93 for evenly breaking up the materials, and the auger 93 is rotatably connected to the telescopic end of the hydraulic cylinder 94 on the front side.

[0022] It should be noted that, during asphalt pavement construction, the device can be used for auxiliary operation. First, the water cover is rotated open, and then water is added to the sprinkler assembly 7. Then the operator can start the drive assembly 6. The operation of the drive assembly 6 will cause the roller 2 to rotate. At this time, the operator can adjust the travel direction of the device by controlling the handle on the left side of the first mounting plate 3. During the movement of the device, the travel wheel will assist the roller 2 to make the movement more convenient. At the same time, the hydraulic cylinder 94 is started, and the telescopic end of the hydraulic cylinder 94 will extend downward, so that the installation box 91 and the auger 93 move downward, so that the auger 93 can contact the material, and the drive motor 92 is started. The output shaft of the drive motor 92 will drive the auger 93 to rotate. As the auger 93 rotates, the material will be evenly dispersed to avoid gaps between the materials, enhance the bonding stability and firmness of the materials, and after the dispersion process is completed, the material distribution will be more even, so that the asphalt surface can be smoother.

[0023] Example 2

[0024] On the basis of Example 1, Figure 2 and Figure 4 As shown, it also includes a vibration mechanism 10, which includes a second mounting plate 103. The second mounting plate 103 is installed in the roller 2, and a servo motor 101 is installed on the second mounting plate 103. The eccentric piece 102 is connected to the output shaft of the servo motor 101.

[0025] It should be noted that after the asphalt is evenly broken up, the servo motor 101 can be started. The rotation of the output shaft of the servo motor 101 will cause the eccentric 102 to rotate at high speed, so that the roller 2 can squeeze the damper 4, and then the roller 2 starts to vibrate continuously, further expelling the bubbles in the material.

[0026] It should be understood that this embodiment is only used to illustrate the present invention and is not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
