It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0034] like Figure 1-7As shown, the utility model provides an asphalt paving device for an elevated bridge, including a base 1, a mixing tank 2 is fixedly connected to the surface of the base 1, a loading frame 3 is fixedly connected to the upper surface of the mixing tank 2, two rollers 4 are rotatably connected to the surface of the base 1, four scrapers 5 are fixedly connected to the inner wall of the base 1, and the four scrapers 5 are grouped in pairs, two adjusting plates 7 are rotatably connected to the lower surface of the base 1, a discharge hopper 9 is fixedly connected to the lower surface of the base 1, a cleaning device 6 is provided on the surface of the base 1, and a dredging device 8 is provided on the upper surface of the mixing tank 2.

[0035] The specific settings and functions of the cleaning device 6 and the dredging device 8 will be described in detail below.

[0036] like Figure 1 - Figure 4 As shown, the cleaning device 6 includes four extension plates 604, and the four extension plates 604 are grouped in pairs. The surfaces of the two extension plates 604 are rotatably connected to round rods 605, and both ends of the round rods 605 are fixedly connected to second gears 610. Both ends of the two roller shafts 4 are fixedly connected to connecting rods 601, and the arc surface of the connecting rod 601 is fixedly connected to the first gear 602. The surfaces of the first gear 602 and the second gear 610 are meshed with internal toothed belts 603. The arc surface of the round rod 605 is fixedly connected to three cleaning plates 606. The four cleaning plates 606 are all in an arc shape, and can drive the cleaning plates 606 to work by rotating when the roller shaft 4 is working, and then the asphalt stuck on the scraper 5 can be cleaned by the driving of the cleaning plates 606, so that the cleaning will not accumulate on the scraper 5, and will not affect the cleaning effect of the scraper 5, and will not affect the rotation of the roller shaft 4. The base 1 is used in a flexible manner and the flattening work is convenient. The inner walls of the three cleaning plates 606 are glued with anti-sticking plates 607. The anti-sticking plates 607 are made of polytetrafluoroethylene. Since the anti-sticking plates 607 are made of polytetrafluoroethylene, they have good anti-stick properties and can effectively prevent asphalt from sticking, which further facilitates the cleaning of asphalt. The surface of the base 1 is fixedly connected with a mounting frame 608, and the surface of the mounting frame 608 is slidably connected with a collecting frame 609. Due to the addition of the collecting frame 609, the cleaned asphalt can be collected for convenient recycling. Both sides of the mounting frame 608 are rotatably connected with rotating plates 611, and the rotating plates 611 can be rotated and then attached to the surface of the collecting frame 609. The friction force generated by the attachment can enable the rotating plate 611 to limit the collecting frame 609, so that the collecting frame 609 will not slide and fall during the collection work.

[0037] like Figure 1 and Figure 5 - Figure 7As shown, the dredging device 8 includes two slide rails 81, and the sides of the two slide rails 81 close to each other are slidably connected to a moving frame 82, and the surface of the moving frame 82 is slidably connected to a slide rod 83, and the end of the slide rod 83 close to the feeding frame 3 is fixedly connected to a dredging plate 87, which can complete the rapid dredging of the inside of the feeding frame 3 through the dredging plate 87 when the feeding frame 3 is blocked, which is convenient for the asphalt feeding work, and further enables the asphalt paving work to start quickly, and is convenient for the use of the paving device, the surface of the slide rod 83 is fixedly connected to a first disc 84, and the arc surface of the first disc 84 is rotatably connected to the second disc 85, and the surface of the slide rod 83 is sleeved with a spring 86, and the two ends of the spring 86 are respectively fixedly connected to the second disc 85 and the moving frame 82. After the asphalt is completely poured into the mixing tank 2, the staff can loosen the slide bar 83, and the slide bar 83 will be reset by the spring 86, which is convenient for the subsequent use of the dredging device 8 and will not affect the daily use of the feeding frame 3. Circular grooves 88 are provided on both sides of the movable frame 82, and two clip plates 89 are fixedly connected to the upper surface of the mixing tank 2. The arc surfaces of the two clip plates 89 are adapted to the size of the circular grooves 88. When the dredging device 8 is not in use, the circular grooves 88 can be moved to the position of the clip plates 89. At this time, the clip plates 89 can be clipped together with the circular grooves 88, which can complete the limiting of the movable frame 82, so that the movable frame 82 will not move when placed, which is convenient for the feeding of asphalt when there is no blockage.

[0038] The overall working principle is that when the viaduct asphalt is paved, the asphalt is discharged from the inside of the mixing tank 2 through the discharge hopper 9, and then the paving thickness can be adjusted by the adjustment plate 7, and the two rollers 4 can be further moved to flatten the paved asphalt, thereby completing the asphalt paving work. When the asphalt is flattened by the rollers 4, the asphalt stuck on the arc surface of the rollers 4 will be scraped off by the scraper 5, and then stick to the surface of the scraper 5. When the rollers 4 rotate, it will drive the connecting rod 601 to rotate, and the asphalt will be flattened. The first gear 602 is driven to rotate. Since the teeth of the first gear 602 and the teeth of the second gear 610 are meshed with the inner toothed belt 603, the second gear 610 can be driven to rotate. The rotation of the second gear 610 can drive the round rod 605 to rotate, and then drive the cleaning plate 606 to rotate. The cleaning plate 606 can clean the asphalt on the surface of the scraper 5. At the same time, the inner wall of the cleaning plate 606 is provided with an anti-sticking plate 607. Since the anti-sticking plate 607 is made of polytetrafluoroethylene, it has good anti-sticking properties. The asphalt can be effectively prevented from sticking, and the cleaning of the asphalt is further facilitated. At the same time, after the asphalt is cleaned, it will fall into the inside of the collecting frame 609. The collecting frame 609 can be mounted on the surface of the mounting frame 608 by sliding. Due to the addition of the collecting frame 609, the cleaned asphalt can be collected, which is convenient for recycling. There are rotating plates 611 on both sides of the mounting frame 608. The rotating plates 611 can rotate and then fit on the surface of the collecting frame 609. The friction generated by the fitting can limit the collecting frame 609 by the rotating plates 611, so that the collecting frame 609 will not slide and fall when the collecting work is being carried out. By setting the cleaning device 6, the cleaning plate 606 can be driven to work by rotation when the roller 4 is working, and then the asphalt stuck on the scraper 5 can be cleaned by the driving of the cleaning plate 606, so that the cleaning will not accumulate on the scraper 5, and will not affect the cleaning effect of the scraper 5, will not affect the rotation and use of the roller 4, and at the same time facilitate the flattening work.

[0039] When loading, asphalt will be loaded from the loading frame 3. The loaded material is prone to accumulation, which will affect the progress of the asphalt paving work. By sliding the slide bar 83 up and down in the movable frame 82, the dredging plate 87 can be driven to dredge the loading port inside the loading frame 3, and the slide bar 83 can be rotated, which will speed up the loading speed of the asphalt. At the same time, the movable frame 82 can slide on the slide rail 81, which further facilitates the dredging speed of the asphalt inside the loading frame 3 by the dredging plate 87. After the asphalt is completely poured into the mixing tank 2, the staff can release the slide bar 83, and the slide bar 83 will be reset by the spring 86, which is convenient for dredging. The subsequent use of the unblocking device 8 will not affect the daily use of the feeding frame 3. When the unblocking device 8 is not in use, the circular groove 88 can be moved to the position of the clamping plate 89. At this time, the clamping plate 89 can be clamped together with the circular groove 88, and the movable frame 82 can be limited so that the movable frame 82 will not move when placed, which is convenient for the loading of asphalt when there is no blockage. By setting the unblocking device 8, when the feeding frame 3 is blocked, the unblocking plate 87 can be used to quickly unblock the inside of the feeding frame 3, which is convenient for the loading of the asphalt, and further enables the asphalt laying work to start quickly, which is convenient for the use of the laying device.
