DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment:

[0031] like Figure 1-4 As shown, a pothole filling device for road and bridge maintenance includes a frame 1 and legs 2 fixedly connected to the four corners of the lower end surface of the frame 1, and a universal wheel 3 is arranged at the free end of the leg 2. A cleaning mechanism 4, a storage barrel 5, a leveling mechanism 6 and a scraping mechanism 7 are arranged on the frame 1 from front to back. The cleaning mechanism 4 is used to clean the inside of the pothole, and then fill the filling slurry in the storage barrel 5 into the pothole. The unevenly distributed filling slurry in the pothole is stirred and regularized by the leveling mechanism 6, and the vibrating pump 67 in the leveling mechanism 6 is used to make the filling slurry in the pothole become compact to improve the work quality. Then, the filling slurry is scraped and leveled by the scraping mechanism 7 to make it level with the original road surface. The scraping mechanism 7 can change the scraping range to improve the scraping efficiency.

[0032] like Figure 1-4As shown, the scraping mechanism 7 includes a connecting rod 71 fixedly connected to the lower end surface of the frame 1, and the free ends of the two connecting rods 71 ​​are fixedly connected to the first scraper 72. Both ends of the first scraper 72 are hinged with second scrapers 74 through hinges 73. The two second scrapers 74 can rotate around the hinges 73. The ends of the two second scrapers 74 that rotate close to each other are detachably connected through a first buckle 75. When the two second scrapers 74 rotate away from each other until they are level with the length direction of the first scraper 72, the two second scrapers 74 are detachably connected to the first scraper 72 through the second buckle 76. The lower end surfaces of the first scraper 72 and the second scraper 74 are level with the lowest point of the universal wheel 3, so that the filling slurry after scraping by the scraping mechanism 7 can be level with the original road surface. When the scraping range of the first scraper 72 in the length direction cannot cover the pothole, open the first buckle 75 and rotate the two second scrapers 74, rotate the second scraper 74 to be flush with the first scraper 72 in the length direction, connect the second scraper 74 to the first scraper 72 through the second buckle 76, and then push the frame 1 to make the scraping mechanism 7 scrape the filling slurry in the pothole. The scraping mechanism 7 can change the scraping range and improve the scraping work efficiency.

[0033] like Figure 1-4 As shown, a first arc block 77 is provided on the side of the first scraper 72 close to the leveling mechanism 6, and a second arc block 78 is provided on the front side of the second scraper 74 after being connected to the first scraper 72 by a second buckle 76. The cross-sections of the first arc block 77 and the second arc block 78 are the same. The provision of the first arc block 77 and the second arc block 78 can help the leveling mechanism 7 to level the filling slurry in the potholes.

[0034] like Figure 5-9 As shown, the cleaning mechanism 4 includes a first mounting frame 41 sliding on the frame 1, and one end of the first mounting frame 41 located below the frame 1 is fixedly connected to two first connecting plates 42, and a first rotating rod 43 is rotatably connected between the two first connecting plates 42. A first motor 44 is installed on one side of the first connecting plate 42, and the output end of the first motor 44 is fixedly connected to the first rotating rod 43. At least two rows of brushes 45 are arranged on the rod body of the first rotating rod 43, and the brushes 45 in adjacent rows are staggered. A first electric push rod 46 is arranged on the frame 1, and the telescopic end of the first electric push rod 46 is fixedly connected to one end of the first mounting frame 41 located above the frame 1. By extending and retracting the first electric push rod 46, the first mounting frame 41 slides in the vertical direction on the frame 1, changing the height of the first rotating rod 43 from the road surface, so that the brush 45 penetrates into the pothole, and the first rotating rod 43 rotates through the output of the first motor 44, and the brush 45 rotates to clean the pothole, and cooperates with the staff to push the frame 1 to clean the debris in the pothole to the same side, so as to facilitate the collection and treatment of the debris in the pothole.

[0035] like Figure 1As shown, the lower end of the storage barrel 5 is connected to a discharge pipe 51, and the free end of the discharge pipe 51 is connected to an electric control valve 52. Opening the electric control valve 52 can allow the filling slurry in the storage barrel 5 to be discharged from the discharge pipe 51 into the pothole to be filled.

[0036] like Figure 5-9 As shown, the leveling mechanism 6 includes a second mounting frame 61 sliding on the frame 1, and one end of the second mounting frame 61 located below the frame 1 is fixedly connected to two second connecting plates 62, and a second rotating rod 63 is rotatably connected between the two second connecting plates 62. A second motor 64 is installed on the second connecting plate 62 on one side, and the output end of the second motor 64 is fixedly connected to the second rotating rod 63, and a spiral blade 65 is provided on the second rotating rod 63. The lower end of the second mounting frame 61 is also connected to an elastic connecting rope 66, and the free end of the elastic connecting rope 66 is fixedly connected to a vibration pump 67. A second electric push rod 68 is also provided on the frame 1, and the telescopic end of the second electric push rod 68 is fixedly connected to one end of the second mounting frame 61 located above the frame 1. By extending and retracting the second electric push rod 68, the second mounting frame 61 slides in the vertical direction on the vehicle frame 1, changing the height of the second rotating rod 63 and the vibration pump 67 from the road surface, so that the vibration pump 67 and the spiral blade 65 penetrate into the filling slurry, and the filling slurry unevenly distributed in the potholes is stirred and regularized by the rotation of the spiral blade 65, and the filling slurry in the potholes is made compact by the vibration pump 67, thereby improving the work quality.

[0037] like Figure 5-9 As shown, the cleaning mechanism 4 also includes a slide groove 47 opened on the first rotating rod 43 and adapted to the number and position of the brush 45. An insert block 48 slides in the slide groove 47. A spring 49 is connected between one end of the insert block 48 located in the slide groove 47 and the inner wall of the slide groove 47. The end of the insert block 48 located outside the slide groove 47 is connected to the brush 45. The cross-section of the slide groove 47 is a convex shape, and the diameter of its opening is smaller than the internal diameter. An annular limiting flange is provided at one end of the insert block 48 located in the slide groove 47. The diameter of the annular flange is the same as the inner diameter of the slide groove 47 to prevent the insert block 48 from completely falling out of the slide groove 47. The brush 45 is a hard brush. The bottom of the pothole is uneven. After the brush 45 is pushed into the pothole by the extension and retraction of the first electric push rod 46, the brush 45 located at a higher position in the bottom of the pothole is squeezed and deformed, causing the plug block 48 to move into the slide groove 47 and squeeze the spring 49, so that each brush 45 can adapt to the pothole with an uneven bottom. The side wall of the end of the plug block 48 close to the brush 45 is set as an arc surface. During the rotation of the first rotating rod 43, if the plug block 48 is in direct contact with the bottom of the pothole, the arc surface helps the plug block 48 to go deep into the slide groove 47 and squeeze the spring 49, which helps the device to cope with the uneven bottom of the pothole and improves the cleaning efficiency.

[0038] like Figure 5-9As shown, the cleaning mechanism 4 also includes a shielding member 410 fixedly connected between the two first connecting plates 42, and a plurality of cleaning teeth 411 are fixedly connected at equal intervals to the lower end of the shielding member 410. The cleaning teeth 411 are arranged to block some debris adhered to the brush 45, thereby improving the cleaning efficiency of the cleaning mechanism 4.

[0039] like Figure 1 , Figure 2 As shown, the upper end of the storage barrel 5 is fixedly connected to a third mounting frame 53, and a third motor 54 is installed on the third mounting frame 53. The output end of the third motor 54 passes through the third mounting frame 53 and is fixedly connected to a spiral feed rod 55. The output of the output end of the third motor 54 causes the spiral feed rod 55 to rotate, which helps to fill the slurry through the discharge pipe 51.

[0040] The first motor 44, the first electric push rod 46, the second motor 64, the second electric push rod 68, the third motor 54, the electric control valve 52 and the vibration pump 67 are all electrically connected to the battery 8 arranged on the frame 1, and are electrically connected to the control unit (not shown in the figure).

[0041] The working principle of a pothole filling device for road and bridge maintenance in this embodiment is as follows: when in use, the debris in the pothole is first cleaned by the cleaning mechanism 4, and after cleaning, the filling slurry is added to the storage barrel 5, the electric control valve 52 is opened and the filling slurry is added to the pothole in cooperation with the mobile frame 1, and after adding, the unevenly distributed filling slurry in the pothole is stirred and regularized by the leveling mechanism 6, and the vibrating pump 67 in the leveling mechanism 6 is used to make the filling slurry in the pothole compact, thereby improving the work quality, and by scraping and leveling The mechanism 7 scrapes the filling slurry to make it level with the original road surface. When the scraping range of the first scraper 72 in the length direction cannot cover the pothole, open the first buckle 75 and rotate the two second scrapers 74. The second scraper 74 is rotated to be level with the first scraper 72 in the length direction. The second scraper 74 is connected to the first scraper 72 through the second buckle 76, and then the frame 1 is pushed to make the scraping mechanism 7 scrape the filling slurry in the pothole level. The scraping mechanism 7 can change the scraping range and improve the scraping work efficiency.
