Description

Technical Field

[0001] The utility model relates to the field of airport pavement construction, in particular to an automatic roughening device for an airport runway. Background Art

[0002] Whether constructing a civil or military airport, the airfield is a crucial sub-project. Whether the concrete pavement of the runway, taxiway, access road, and apron has sufficient load-bearing capacity, good driving performance, and good surface friction properties directly impacts aircraft safety when the pavement is wet or flooded. This is a key consideration during the acceptance inspection process for civil aviation airports in my country. To ensure excellent skid resistance, the runway surface requires a roughening treatment to increase surface friction and enhance aircraft grip during takeoff and landing. This roughening treatment helps prevent aircraft from sliding, reduces braking distances, and improves safety in slippery conditions.

[0003] Traditional scraper-type roughening devices treat runway surfaces through mechanical scraping. They typically include one or more fixed scrapers that contact the runway surface as the device advances, removing the smooth surface layer and creating a rough texture. However, since the roughening plates are fixed to a frame, the scraping depth is difficult to adjust, limiting the roughness of the runway surface. Therefore, an automatic airport runway roughening device was proposed to address this issue. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 3 , The utility model provides an embodiment: an automatic roughening device for the runway surface of an airport, comprising a connecting frame 1, a frame body 2 fixedly connected to the lower surface of the connecting frame 1, a roughening assembly provided on the side wall of the frame body 2, and the roughening assembly is used to roughen the ground, a supporting frame 5 fixedly connected to the upper surface of the frame body 2, a round rod 6 provided inside the supporting frame 5, a concave hole 26 provided on the side wall of the round rod 6, a connecting rod 1 7 rotatably connected to the inside of the supporting frame 5, a limiting assembly fixedly connected to the side wall of the connecting rod 1 7, a limiting assembly used to lock the position of the connecting rod 1 7, a gear 1 9 fixedly connected to the side wall of the connecting rod 1 7, a connecting rod 2 10 rotatably connected to the inside of the supporting frame 5, a gear 2 11 fixedly connected to the side wall of the connecting rod 2 10, the gear 2 11 meshes with the concave hole 26, and the connecting rod The side wall of the second 10 is fixedly connected to the gear three 12, and the gear three 12 is meshed with the gear one 9. The interior of the support frame 5 is fixedly connected to the fixed block 13, and the side wall of the support frame 5 is provided with a square groove 15. The roughening assembly includes a fixed plate 3 and a roughening plate 4. The upper surface of the fixed plate 3 is fixedly connected to the lower surface of the round rod 6, and the side wall of the roughening plate 4 is slidably connected to the inside of the fixed plate 3. The limiting assembly includes a ratchet 8 and a pawl 14. The side wall of the ratchet 8 is fixedly connected to the side wall of the connecting rod one 7, and the side wall of the pawl 14 is rotatably connected to the side wall of the fixed block 13. The ratchet 8 is engaged with the pawl 14. A plurality of concave holes 26 are provided and are arranged in a linear array. The side wall of the connecting rod one 7 is fixedly connected to the handle 25, the side wall of the connecting frame 1 is fixedly connected to the handrail 23, and the side wall of the frame body 2 is provided with a wheel 24;

[0032] When the equipment is used to roughen the airport runway, if the height of the roughening plate 4 needs to be adjusted, the handle 25 is turned to rotate the connecting rod 1 7 connected to it. The rotation of the connecting rod 1 7 drives the gear 1 9 fixed on the side wall to rotate, and the gear 1 9 is meshed with the gear 3 12. Under the meshing action, the gear 3 12 will also rotate accordingly. As the gear 3 12 rotates, the fixed connecting rod 2 10 also rotates. The rotation of the connecting rod 2 10 will cause the gear 2 11 fixed on the side wall to start to rotate, and the gear 2 11 is meshed with the recessed hole 26 opened on the side wall of the round rod 6, so that the round rod 6 moves. The movement of the round rod 6 drives the fixed plate 3 to move, thereby realizing the height adjustment of the roughening plate 4. When the height adjustment of the roughening plate 4 is completed, the pawl 14 will lock the ratchet 8 to prevent it from rotating. When the height of the roughening plate 4 needs to be lowered, the pawl 14 needs to be moved first to disengage it from the locked state of the ratchet 8, and then the handle 25 is turned in the opposite direction to rotate the connecting rod 7 again, thereby driving the gear 9 to rotate. Through the meshing action of the gear 9 and the gear 3 12, the gear 3 12 will also rotate accordingly. The rotation of the gear 3 12 will drive the connecting rod 2 10 to rotate, thereby rotating the gear 2 11. The meshing action of the gear 2 11 and the recessed hole 26 will cause the round rod 6 to descend, thereby completing the adjustment of the roughening plate 4. Through a series of adjustments, the height change of the roughening plate 4 is completed, so that the scraping depth can be adjusted.

[0033] Reference Figure 2 and Figure 4 , the fixed plate 3 is fixedly connected to the fixed frame 16, the fixed frame 16 is fixedly connected to the sliding rod 17, the fixed frame 16 is slidably connected to the card block 18, the side wall of the sliding rod 17 is provided with a spring 19, the side wall of the card block 18 is fixedly connected to the connecting block 20, the connecting block 20 is rotatably connected to the connecting plate 21, the side wall of the connecting plate 21 is rotatably connected to the button 22, the card block 18 is slidably connected to the side wall of the sliding rod 17, one end of the spring 19 is fixedly connected to the fixed frame 16, the other end of the spring 19 is fixedly connected to the side wall of the card block 18, the side wall of the card block 18 is slidably connected to the inside of the roughening plate 4, and the side wall of the button 22 is slidably connected to the inside of the fixed frame 16;

[0034] During the installation of the roughened plate 4, the button 22 is pressed to squeeze it inward, driving the connecting plate 21 to rotate, and the block 18 fixed by the connecting block 20 is moved. The movement of the block 18 will exert pressure on the spring 19, causing it to contract. As the spring 19 contracts, the block 18 is driven to enter the interior of the fixed frame 16. Next, the roughened plate 4 is placed inside the fixed plate 3, and the button 22 is pressed before releasing. After releasing the button 22, the spring 19 will lose the pressure exerted on it by the block 18 and start to rebound. The rebound of the spring 19 will push the block 18 to be inserted into the interior of the roughened plate 4, thereby fixing the roughened plate 4, making the fixation of the roughened plate 4 convenient, and facilitating the problem of the roughened plate 4 being severely worn and needing to be replaced in the later stage.

[0035] Working principle: When the equipment is used for roughing the airport runway, the handle 25 can be turned to rotate the connecting rod 17, and the rotation of the connecting rod 17 drives the gear 19 fixed on the side wall to rotate. The gear 19 is meshed with the gear 3 12, and the gear 3 12 is driven to rotate under the meshing action. The rotation of the gear 3 12 drives the connecting rod 2 10 to rotate. The rotation of the connecting rod 2 10 drives the gear 2 11 to rotate. The gear 2 11 is meshed with the concave hole 26, so that the round rod 6 drives the fixed plate 3 to move, so that the roughing plate 4 Adjust the height. When the height adjustment is completed, the pawl 14 will fix the ratchet 8 to prevent it from rotating. When the roughening plate 4 is lowered, first move the pawl 14 to cancel the clamping of the ratchet 8, and then turn the handle 25 in the opposite direction to rotate the connecting rod 7, drive the gear 9 to rotate, and then rotate the gear three 12 through the meshing effect. The gear three 12 drives the connecting rod two 10 to rotate, and the gear two 11 is rotated. Through the meshing effect of the gear two 11 and the recessed hole 26, the round rod 6 is lowered to complete the adjustment of the roughening plate 4.

[0036] When installing the roughened plate 4, the button 22 is pressed inward to make the connecting plate 21 rotate inside the connecting block 20, driving the block 18 to move. The movement of the block 18 squeezes the spring 19 to make it contract, so that the block 18 enters the fixed frame 16. After the roughened plate 4 is placed into the fixed plate 3, the button 22 is released, so that the spring 19 loses the squeezing of the block 18 and rebounds, so that the spring 19 pushes the block 18 to insert into the roughened plate 4 for fixation.
