Description
Technical Field
[0001] The utility model relates to the technical field of concrete construction, in particular to an auxiliary device for foamed asphalt concrete construction. Background Art
[0002] Foamed asphalt concrete construction is a unique asphalt concrete pavement construction technology. Its core is to foam asphalt, mix it with aggregate and other materials to create asphalt concrete, and then pave the surface. In foamed asphalt concrete, aggregate particle sizes vary significantly from coarse to fine aggregate; mineral powder has a very fine particle size. Foamed asphalt has a unique foaming structure and low initial viscosity. Using a mixing aid ensures a uniform blend of these materials, preventing uneven mixing that could affect pavement quality.
[0003] In the prior art, some auxiliary devices usually put the materials to be mixed into the inside of the mixing barrel and then mix and stir them. However, when the mixed materials are discharged, the fine aggregates are easily squeezed and piled up. Since the fine aggregate particles are small, the gaps between them are also small. Under the action of gravity, the friction between the particles is relatively large, and it is easy to form blockages in the discharge port or discharge pipe. This requires manual use of tools to remove the blocked materials, which consumes a lot of time and reduces production efficiency. Therefore, in response to the above shortcomings, a foamed asphalt concrete construction auxiliary device is proposed. Utility Model Content

[0024] 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.
[0025] Reference Figure 1 and Figure 3The present invention provides an embodiment of a foamed asphalt concrete construction auxiliary device, comprising a support plate 1. A support frame 2 is fixedly connected to the top right side of the support plate 1. A lifting assembly for lifting is fixedly connected to the top left side of the support frame 2. A control assembly for adjustment is rotatably connected to the right end of the support frame 2. The control assembly includes two handles 5. These two handles 5 are essential for the operator to interact with the device. The operator controls certain functions of the device by manipulating the handles 5. The left end of the handle 5 is rotatably connected to the right inner side of the support frame 2. This rotatable connection allows the handle 5 to rotate flexibly within the right inner side of the support frame 2, similar to the relationship between a door hinge and a door frame, providing the necessary range of motion for the handle 5. Support rods 6 are fixedly connected to the adjacent sides of the two handles 5. Support rods 6 serve as a connection and force transmission mechanism within the control assembly. Rotational movement of the handles 5 is transmitted to other related components via the support rods 6. An electric push rod 7 is rotatably connected to the bottom right end of the support frame 2. The electric push rod 7 is a device that uses electrical energy to achieve telescopic movement. Its drive end is rotatably connected to the bottom end of the support rod 6. When the operator operates the handle 5, the handle 5 drives the support rod 6 to rotate. The rotation of the support rod 6 causes the driving end of the electric push rod 7 to rotate and produce telescopic movement, thereby adjusting the position of the handle 5. The bottom end of the lifting assembly is fixedly connected to a sealing cover 8;
[0026] The lifting assembly includes a loading block 3, the right end of which is fixedly connected to the left top end of the support frame 2, which provides an installation base for other components in the lifting assembly. The left end of the loading block 3 is fixedly connected to a cylinder 4, which is a device that realizes telescopic movement by gas pressure drive, and its driving end is fixedly connected to the top of the sealing cover 8. When the sealing cover 8 needs to be opened, the driving end of the cylinder 4 contracts, driving the sealing cover 8 to rise; when the sealing cover 8 needs to be closed, the driving end of the cylinder 4 extends, causing the sealing cover 8 to descend and contact the top of the mixing barrel 9, thereby achieving the sealing of the mixing barrel 9. The top end of the support plate 1 is fixedly connected to the mixing barrel 9, which is the main place for the mixing operation of the foamed asphalt concrete. A discharge pipe 10 is fixedly connected to one side of the outer bottom end of the mixing barrel 9, and the discharge pipe 10 is used to discharge the mixed material out of the mixing barrel 9. The left side of the outside of the discharge pipe 10 is threadedly connected to a blocking cover 11, which is threadedly connected to the discharge pipe 10 and can be easily opened or closed to control the start and stop of the discharge.
[0027] Reference Figures 2 to 4, a motor 12 is fixedly connected to the bottom of the mixing barrel 9. The motor 12 is the power source of the entire mixing device, and it provides the required power for the mixing process. The bottom end of the motor 12 is fixedly connected to the top of the support plate 1. This fixed connection method ensures the stability of the motor 12 during operation and avoids unnecessary shaking of the motor 12 during operation. The driving end of the motor 12 is fixedly connected to the active bevel gear 13, and the active bevel gear 13 rotates stably under the drive of the motor 12. The top of the active bevel gear 13 is fixedly connected to the rotating rod 14, and the rotating rod 14 rotates synchronously with the rotation of the active bevel gear 13. The fixed connection between them ensures the effective transmission of power. The outside of the rotating rod 14 is fixedly connected to a plurality of stirring blades, which rotate at high speed in the mixing barrel 9 driven by the rotating rod 14, and fully stir and mix the foamed asphalt concrete material in the mixing barrel 9. The bottom end of the mixing barrel 9 is fixedly connected to a receiving block 15, which provides a stable rotational support point for the bottom end of the rotating rod 14. The bottom end of the rotating rod 14 is rotationally connected to the top end of the receiving block 15. At the same time, the top end of the driving bevel gear 13 is rotationally connected to the top end of the receiving block 15. This dual rotation connection ensures the stability and accuracy of the rotating rod 14 and the driving bevel gear 13 during rotation. The left side of the receiving block 15 is internally rotatably connected to the driven bevel gear 16, and the driving bevel gear 13 and the driven bevel gear 16 are meshed.
[0028] When the active bevel gear 13 rotates, the driven bevel gear 16 is driven to rotate through the meshing action between the gears. This transmission method can effectively change the direction of power transmission. The left side of the driven bevel gear 16 is fixedly connected to a fixed rod 17. The fixed rod 17 rotates as the driven bevel gear 16 rotates. The fixed connection between them ensures the continuous transmission of power. The outside of the fixed rod 17 is fixedly connected to an auger blade 18. The auger blade 18 rotates under the drive of the fixed rod 17, pushing the material toward the discharge pipe 10 while stirring, preventing the accumulation of the material, and facilitating the smooth discharge of the material in the mixing barrel 9. The bottom end of the support plate 1 is fixedly connected to a plurality of universal wheels 19. The presence of the universal wheels 19 allows the entire device to be easily moved to different construction sites, improving the maneuverability and flexibility of the device.
[0029] Reference Figure 1 、 Figure 2 and Figure 5, a plurality of receiving columns 20 are fixedly connected to the outside of the rotating rod 14. These receiving columns 20 provide space for installation and movement of other components, and they are an important part of the entire structure. The outside of the stirring blade and the receiving column 20 are coated with a fluorine-containing coating. The fluorine-containing coating has the characteristic of low surface energy, which enables the stirring blade and the receiving column 20 to reduce the adhesion of the material when in contact with the foamed asphalt concrete material, thereby improving the mixing efficiency and the cleanliness of the equipment. A sliding rod 21 is slidably connected to the inner wall of one side of the receiving column 20, and the sliding rod 21 can slide on the inner wall of one side of the receiving column 20. A scraper 22 is fixedly connected to the far side of the plurality of sliding rods 21. When the rotating rod 14 rotates, the receiving column 20 also rotates. Under the action of centrifugal force, the sliding rod 21 slides outward on the inner wall of one side of the receiving column 20, thereby driving the scraper 22 to move away from the center of the receiving column 20. A chamber 23 is provided inside one side of the accommodating column 20, and the chamber 23 provides a closed installation space for the telescopic spring 24 and the limiting plate 25;
[0030] The interior of the chamber 23 is provided with a telescopic spring 24. The telescopic spring 24 is a component that can elastically deform and store energy when subjected to force. It plays an important role in regulating and resetting the movement of the entire structure. The adjacent sides of the multiple sliding rods 21 are fixedly connected to a limit plate 25. The outer portion of the limit plate 25 is slidably connected to the interior of the chamber 23. One end of the telescopic spring 24 is fixedly connected to one side of the interior of the chamber 23, and the other end is fixedly connected to one side of the limit plate 25. The elastic restoring force of the telescopic spring 24 keeps the scraper 22 in the proper position, ensuring the normal operation of the scraper 22, thereby effectively scraping away residues on the inner wall of the mixing barrel 9 and keeping the inner wall of the mixing barrel 9 clean.
[0031] Working principle: First, in the initial state, the sealing cover 8 is covered on the top of the mixing barrel 9, and the sealing cover 8 is opened by starting the cylinder 4. Then, the electric push rod 7 is started to make the support rod 6 drive the handle 5 to move, and the position of the handle 5 is adjusted to facilitate the staff to better drive the entire device. The universal wheel 19 is used to push the device to the appropriate position. Then, when it is necessary to add materials to the mixing barrel 9, the driving end of the cylinder 4 on the object block 3 drives the sealing cover 8 to rise, and the sealing cover 8 is separated from the top of the mixing barrel 9, so that the raw materials of the foamed asphalt concrete can be added to the mixing barrel 9.
[0032] After adding the materials, replace the sealing cover 8 on the top of the mixing barrel 9 and start the motor 12. The motor 12 drives the driving bevel gear 13 to rotate, and the driving bevel gear 13 drives the driven bevel gear 16 meshing with it to rotate. The rotation of the driving bevel gear 13 also drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the stirring blades on its outside to stir and mix the materials in the mixing barrel 9. At the same time, the rotation of the rotating rod 14 drives the fixed rod 17 to rotate, and the rotation of the fixed rod 17 drives the auger blades 18 to rotate. The auger blades 18 rotate at the bottom of the mixing barrel 9, pushing the materials toward the discharge pipe 10 while stirring, preventing the materials from accumulating in the discharge pipe 10 and facilitating subsequent discharge.
[0033] During the mixing process, the rotation of the rotating rod 14 also drives the accommodating column 20 to rotate. When the accommodating column 20 rotates, due to the action of centrifugal force, the sliding rod 21 slides on the inner wall of one side of the accommodating column 20. The sliding of the sliding rod 21 drives the scraper 22 to slide in the direction away from the center of the accommodating column 20. The telescopic spring 24 is stretched and can provide adaptive force to ensure that the scraper 22 fits tightly against the inner wall of the mixing barrel 9. During the sliding process, the scraper 22 scrapes the inner wall of the mixing barrel 9 to scrape off the residue on the inner wall to ensure the cleanliness of the inner wall of the mixing barrel 9. After the mixing is completed, if the material is to be discharged, open the cover 11 threaded on the left side of the discharge pipe 10. Under the push of the auger blade 18, the mixed material is discharged through the discharge pipe 10.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
