Description

Technical Field

[0001] This utility model relates to the field of road and bridge repair technology, specifically a road and bridge crack filling and smoothing device. Background Technology

[0002] As important public construction projects in my country, roads and bridges not only provide convenience for people's travel, but also play a certain role in promoting national and social development and progress. During the construction of roads and bridges, concrete cracks often occur due to various reasons. To solve the cost problem, asphalt is generally used to repair the cracks.

[0003] A search revealed that utility model patent application number 202222481315.5, entitled "A Bridge Crack Filling Device," features a base plate with casters mounted on its lower surface, a storage tank mounted on its upper surface, a discharge port on one side of the bottom of the storage tank connected to a guide pipe, and a guide nozzle connected to the other end of the guide pipe. A flow-limiting component is fitted onto the guide pipe and positioned around the guide nozzle. A camera is mounted on the flow-limiting component. This utility model, through the interconnection of the base plate, storage tank, casters, guide pipe, flow-limiting component, pressure pump, controller, and camera, allows adjustment of the distance between the two limiting plates in the flow-limiting component according to the crack width, ensuring that the width of the flowing asphalt precisely matches the crack width. The camera facilitates worker observation of the crack on a monitor, thereby improving work efficiency.

[0004] Although the device can fill the cracks with asphalt, it cannot smooth the filled asphalt. Workers still need to use tools to smooth it after filling, which increases the number of steps and time, reduces work efficiency, and increases the labor intensity of workers due to the lack of a smoothing function. In addition, manual smoothing may be uneven, affecting the repair quality. Utility Model Content

[0023] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0024] A bridge and road crack filling and leveling device according to this specific embodiment includes a movable platform 1, with rollers installed on all four sides of the surface of the movable platform 1. A support frame 2 is fixed in the middle of the top of the movable platform 1. A storage tank 3 is fixed inside the support frame 2 and is filled with asphalt. A mixing device is installed inside the storage tank 3. A material pump 4 is fixed on the left side of the top of the movable platform 1 and is connected to the storage tank 3. A discharge pipe 5 is connected to the left side of the material pump 4. Handrails 6 are fixed at the front and rear sides of the right side of the top of the movable platform 1. An installation box 7 is fixed on the right side of the top of the movable platform 1. A reciprocating structure 8 is movably connected inside the installation box 7. A fixing frame 9 is fixed on the top of the movable platform 1 and located on the right side of the installation box 7. A swing frame 10 is rotatably connected to the top of the fixing frame 9. A fixing sleeve 11 is fixed on the right side of the swing frame 10. An installation rod 12 is slidably connected inside the fixing sleeve 11, and a scraper 13 is fixed at the bottom end of the installation rod 12.

[0025] The reciprocating structure 8 includes a threaded rod 81, a motor 82, a movable block 83, a rack plate 84, a rotating rod 85, and a gear 86. The threaded rod 81 is rotatably connected inside the mounting box 7. The motor 82 is fixed to the front side of the mounting box 7, and the output shaft of the motor 82 passes through the interior of the mounting box 7 and is fixedly connected to the front end of the threaded rod 81. The movable block 83 is located inside the mounting box 7, and the rack plate 84 is fixed to the right side of the movable block 83. The rotating rod 85 is rotatably connected inside the fixed frame 9, and the top end of the rotating rod 85 passes through the fixed frame 9 and is fixedly connected to the swing frame 10. The gear 86 is fixed. In the middle of the surface of the rotating rod 85, the threaded rod 81 has a reciprocating thread, and the threaded rod 81 passes through the movable block 83 and is threadedly connected to the movable block 83. The rack plate 84 meshes with the gear 86. When the motor 82 is turned on, the output shaft of the motor 82 will drive the threaded rod 81 to rotate, which will cause the movable block 83 to reciprocate on the surface of the threaded rod 81, which will cause the movable block 83 to drive the rack plate 84 to move, which will cause the gear 86 to drive the rotating rod 85 to rotate. The swing frame 10 above swings back and forth so that the scraper 13 can scrape the asphalt on the crack.

[0026] A limiting rod 14 is fixed on the right side of the inner wall of the mounting box 7. The limiting rod 14 passes through the movable block 83 and is slidably connected to the movable block 83. The limiting rod 14 can limit the movable block 83, so that the movable block 83 can only move back and forth, improving the stability of the rack plate 84 when it moves, so that the scraper 13 can perform the scraping treatment.

[0027] An electric telescopic rod 15 is fixed to the right side of the bottom of the swing frame 10. A connecting plate 16 is fixed to the bottom end of the output shaft of the electric telescopic rod 15. The mounting rod 12 passes through the connecting plate 16 and is fixedly connected to the connecting plate 16. By opening the electric telescopic rod 15, the output shaft of the electric telescopic rod 15 pushes the connecting plate 16 up and down, thereby adjusting the height of the scraper 13. After the cracks on the road and bridge surface are filled, the scraper 13 can be controlled to descend for leveling. During normal pushing, the scraper 13 is controlled to move away from the ground by the electric telescopic rod 15 to avoid unnecessary wear.

[0028] The storage tank 3 is covered with insulation pads 17 on both the top and bottom surfaces. The insulation pads 17 are made of polyurethane foam. The insulation pads 17 can be used to insulate the storage tank 3 and prevent the asphalt from losing its fluidity.

[0029] Mounting frames 18 are bolted to the middle of both the front and rear sides of the mobile platform 1. An exhaust fan 19 is installed inside the mounting frame 18. When asphalt fills the cracks in the road and bridge, the exhaust fan 19 can exhaust the gas generated by the asphalt to both sides of the device, thereby avoiding the gas generated by the asphalt from affecting the workers.

[0030] Its working principle is as follows:

[0031] When cracks appear on the surface of roads and bridges and need to be filled, the workers first move the device to the crack. At this time, the workers align the discharge position of the discharge pipe 5 with the crack, and then turn on the material pump 4. The asphalt inside the storage tank 3 is discharged into the discharge pipe 5 and discharged into the crack through the discharge pipe 5 to fill the crack. At this time, the workers push the handle 6 to move and turn on the motor 82, which causes the swing frame 10 to swing. The scraper 13 below also moves. The workers open the electric telescopic rod 15, which causes the connecting plate 16 to push the installation rod 12 down. After the scraper 13 contacts the ground, it performs a scraping operation. By swinging the scraper 13 back and forth, the asphalt on the crack is scraped and the road surface is kept flat. This completes the filling and scraping operation of the cracks on the road and bridge surface.

[0032] It should be noted that, although specific embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these specific embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
