A milling component for milling highway asphalt pavement during repair is rotatably mounted on the outer surface of the loop handle 1. The milling component includes the milling machine body 2, which is rotatably mounted on the outer surface of the loop handle 1. A first threaded groove 20 is formed on the top of the milling machine body 2, and a third threaded groove 18 and a second threaded groove 19 are formed on both the front and rear sides of the milling machine body 2. Limiting rings 24 are rotatably connected to both the front and rear sides of the milling machine body 2, and the limiting rings 24 are fixedly connected to the loop handle 1. The top of the milling machine body 2 is fixedly connected to the engine body 3. A milling rotor 8 is rotatably connected inside the milling machine body 2. An extension component to extend the service life of the milling assembly is fixedly installed on the top of the milling assembly. The extension component includes a support plate 4 and a portal frame rod 10. The bottom of the support plate 4 and the bottom of the portal frame rod 10 are both fixedly installed on the top of the milling machine body 2. A connecting long plate 11 is movably connected inside the portal frame rod 10. An arc-shaped long plate 14 is fixedly connected to the top of the connecting long plate 11. A portal handle 15 is fixedly connected to the outer side of the arc-shaped long plate 14. A first positioning component for positioning the extension component is fixedly installed at the bottom and inside the extension component. The first positioning component includes a positioning post 22, a positioning square plate 23, and a positioning upright plate 21. The top of the positioning post 22... The top of the part and the positioning square plate 23 are both fixedly installed on the bottom of the arc-shaped long plate 14. The positioning upright plate 21 is fixedly installed inside the portal rod 10. The positioning column 22 is movably installed inside the rod body of the portal rod 10. The positioning square plate 23 is movably installed inside the supporting upright plate 4. The positioning upright plate 21 is movably installed inside the connecting long plate 11. The right side of the extended component is fixedly installed with a first fixing component for fixing the extended component. The first fixing component includes a limiting long plate 12. The left side of the limiting long plate 12 is fixedly installed on the right side of the connecting long plate 11. The inside of the limiting long plate 12 is threadedly connected with a first screw 13. The first screw 13 is threadedly connected to the first threaded groove 20. Through the arrangement of the loop handle 1, the milling component, the extended component, the first positioning component, and the first fixing component, the... The milling component can mill the asphalt pavement of highways during repair, extending the service life of the milling component. The first positioning component positions the extended component, and the first fixing component fixes it. During highway asphalt pavement repair, this device can mill the asphalt pavement. After milling the asphalt pavement, when the device is not used for an extended period, the exposed part of the engine is protected from exposure to the operating environment. This prevents indirect damage caused by dust entering the engine, thus extending the device's service life.

[0025] In use, the initial state of this device is as follows: the exposed part of the engine body 3 is exposed to the use environment, one end of the first screw 13 is located inside the limiting plate 12 and the arc-shaped plate 14 is disengaged from the engine body 3, and the second screw 6 is threadedly connected to the second threaded groove 19. When repairing the asphalt pavement of a highway, when it is necessary to use this device to mill the asphalt pavement of the highway, start the engine body 3, hold the boom handle 1, and push the milling machine body 2 on the asphalt pavement of the highway to move the milling machine body 2, so that the milling rotor 8 rotates along the milling machine body 2, so that the milling machine body 2 can mill the asphalt pavement of the highway while moving. At this time, this device can be used to mill the asphalt pavement of the highway.

[0026] After using this device to mill the asphalt pavement of the highway, when the device is not used for a long time, move the gate-shaped handle 15 so that the first screw 13 corresponds to the first threaded groove 20, so that the connecting long plate 11 slides down into the interior of the gate-shaped rod 10, so that the positioning plate 21 is inserted into the interior of the connecting long plate 11, so that the connecting long plate 11 slides down along the positioning plate 21, so that the limiting long plate 12, the first screw 13, the positioning square plate 23 and the positioning post 22 all move down.

[0027] When the connecting plate 11 slides completely downward into the interior of the portal rod 10, the positioning plate 21 is completely located inside the connecting plate 11. The limiting plate 12 contacts the milling machine body 2 and the portal rod 10 respectively. The arc-shaped plate 14 contacts the portal rod 10 and the supporting plate 4 respectively. The positioning post 22 is located inside the pole of the portal rod 10. The positioning square plate 23 is located inside the supporting plate 4. The arc-shaped plate 14 contacts the exposed part of the engine body 3 and covers the exposed part of the engine body 3. The first screw 13 is rotated so that the first screw 13 is threadedly connected to the first threaded groove 20. At this time, under the action of the arc-shaped plate 14 contacting the exposed part of the engine body 3 and covering the exposed part of the engine body 3, the exposed part of the engine body 3 can be prevented from being exposed to the use environment. This prevents the device from being indirectly damaged by dust entering the engine body 3, thus preventing the device from having a shortened service life and extending its service life.

[0028] In summary, when repairing asphalt pavement on highways, this device enables milling of the asphalt pavement. After milling, when the device is not used for an extended period, the exposed portion of the engine is protected from exposure to the operating environment. This prevents indirect damage caused by dust entering the engine, thus extending the device's service life.

[0029] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown: A milling device for highway asphalt pavement repair includes a support rod 9, a positioning rod 17, a positioning plate 16, and a limiting block 5. A convenient placement component for the milling assembly is fixedly installed on one side of the milling assembly. The convenient placement component includes the support rod 9, one side of which is fixedly installed on one side of the milling machine body 2. A support plate 7 is slidably connected to the other side of the support rod 9 and is slidably connected to the milling machine body 2. A second positioning component for the positioning component is fixedly installed on both one and the other side of the convenient placement component. The second positioning component includes the positioning rod 17 and the positioning plate 16. One side of the positioning rod 17 is fixedly installed on one side of the support plate 7, and one side of the positioning plate 16 is fixedly installed on the other side of the support plate 7. The positioning rod 17 is slidably installed inside the support rod 9, and the positioning plate 16 is slidably installed inside the milling machine body 2. A second positioning component for fixing the convenient placement component is fixedly installed on the top of the convenient placement component. The fixing component includes a limiting block 5, the bottom of which is fixedly installed on the top of the supporting plate 7. The limiting block 5 is slidably connected to the milling machine body 2. The limiting block 5 has a second screw 6 threadedly connected to its interior. The second screw 6 is threadedly connected to the second threaded groove 19 and the third threaded groove 18, respectively. Through the setting of the convenient placement component, the second positioning component, and the second fixing component, the convenient placement component can be conveniently placed, the second positioning component can position the convenient placement component, and the second fixing component can fix the convenient placement component. When repairing highway asphalt pavement, after using this device to mill the highway asphalt pavement, when this device needs to be placed on a flat surface, the bottom of this device can be stably supported, preventing the device from tipping over due to overall tilting, avoiding the difficulty of placement due to tipping over, and making the placement of this device convenient.

[0030] When using this device to repair asphalt pavement on highways, after milling the asphalt pavement, and when the device needs to be placed on a flat surface, rotate the second screw 6 to disengage it from the milling machine body 2 and position one end of the second screw 6 inside the limiting block 5. Move the support plate 7 downwards, allowing it to slide down along the milling machine body 2 and the support rod 9, respectively. This causes the positioning rod 17 to slide down along the inside of the support rod 9, the positioning plate 16 to slide down along the inside of the milling machine body 2, and the limiting block 5 to slide down along the milling machine body 2. When the support plate 7 is moved down to its maximum distance, the second screw 6 corresponds to the third threaded groove 18, and the bottom of the support plate 7 contacts the flat surface. Rotate the second screw 6 in the opposite direction to connect it to the third threaded groove 18. At this point, the device can be placed on the flat surface.

[0031] When this device is placed on a flat surface, the bottom of the supporting plate 7 contacts the flat surface, which allows the bottom of the milling machine body 2 to be stably supported, preventing the milling machine body 2 from tilting or falling over, and making the device easy to place.

[0032] In summary, when repairing asphalt pavement on highways, after milling the asphalt pavement using this device, the bottom of the device can be stably supported when it needs to be placed on a flat surface. This prevents the device from tipping over due to overall tilting, thus avoiding increased placement difficulty caused by tipping over and making placement convenient.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
