Description

Technical Field

[0001] The utility model relates to the technical field of road surface disease repair, and in particular to an integrated milling, paving and pressing device for treating small-scale shallow road surface diseases. Background Art

[0002] Minor localized cracks, crazing, and oil spills are common pavement defects during routine highway maintenance. Prompt and effective treatment can effectively prevent severe structural defects such as cracking and subsidence, saving maintenance costs and ensuring driving safety. However, due to the small size and shallow depth of these defects, large-scale construction equipment cannot be used. Maintenance personnel are forced to manually chisel out the affected areas and perform manual repairs, paving, and compaction.

[0003] While manual repairs provide timely treatment, they lack effective quality control, resulting in often uneven and irregular road surfaces. The repaired areas are more susceptible to serious damage from the prolonged impact of vehicles and rain, compromising driving safety and increasing maintenance costs. This manual approach to treating shallow road defects is also the primary reason why many minor road problems are repeatedly repaired in the same area. Utility Model Content

[0004] The purpose of this utility model is to overcome the above technical deficiencies and provide an integrated milling, paving and pressing device for treating small-scale shallow pavement diseases, so as to solve the technical problems of low efficiency and poor effect in the field of pavement disease repair technology.

[0005] In order to achieve the above technical objectives, the technical solution of the utility model provides an integrated milling, paving and pressing device for treating small-scale shallow pavement defects, comprising:

[0006] Positioning bracket, cleaning component, mixing component, paving component and compacting component; the cleaning component, mixing component, paving component and compacting component are all arranged in the rotating bracket; the positioning bracket and the rotating bracket are both cylindrical; the rotating bracket is built into the positioning bracket and is rotatably connected to the positioning bracket; the circumferential outer wall of the positioning bracket is provided with multi-directional wheels through a steering bracket array; the steering bracket is slidably connected to the positioning bracket to adjust the height of the positioning bracket and the ground; the mixing component is coaxially arranged with the rotating bracket; the mixing component includes a mixing pot, mixing blades and an electric heating wire; the electric heating wire is arranged around the inner wall of the mixing pot; the mixing blades are arranged in the inner cavity of the mixing pot through a mixing shaft.

[0007] Compared with the prior art, the beneficial effects of the present invention include:

[0008] 1. Highly integrated functions effectively save costs. The equipment covers the entire construction cycle of pavement damage treatment, including milling old road, cleaning, preparing repair materials, paving, and compacting. This means that a process that usually requires multiple people and multiple steps can be completed by one person operating a single piece of equipment, effectively saving manpower and material costs.

[0009] 2. Professionalized maintenance and construction, refined disease prevention and control. Because construction is completed through equipment control, and the mixture is mixed, the loose paving coefficient is adjusted, and the compaction thickness is controlled in strict accordance with disease treatment requirements, it is essentially equivalent to integrating and unifying standard large-scale pavement construction processes. This effectively avoids the subjective influence of manual operation and unprofessional construction, thereby achieving the goals of professional construction and refined maintenance, significantly improving the quality of disease treatment.

[0010] 3. Improved efficiency. Since a single device can complete the entire maintenance cycle, and time-consuming tasks such as mixing the mixture can be completed simultaneously during the milling process, the efficiency of disease treatment is greatly improved, the pressure of maintaining traffic during routine maintenance is greatly reduced, and the pressure of long-term lane occupation and traffic congestion caused by long maintenance time is avoided, thereby improving highway operation safety.

[0011] 4. Portability. Because the device is designed for treating small-scale diseases, its overall size is small, making it easy to store in the trunk of common vehicles such as SUVs. Furthermore, the device's built-in wheels make it easy to move, effectively reducing the manpower required to move the device and avoiding the risk of injury. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 This embodiment provides an integrated milling, paving and compacting device for treating small-scale shallow road surface diseases, including: a positioning bracket 1, a cleaning component 2, a mixing component 3, a paving component 4 and a compacting component 5.

[0024] To ensure the personal safety of workers, this embodiment provides an integrated milling, paving and pressing device for treating small-scale shallow pavement defects. Each component is provided with an insulating layer to prevent workers from getting electric shock during operation.

[0025] Furthermore, the cleaning component 2, mixing component 3, paving component 4 and compacting component 5 are all arranged in the rotating bracket 6, the positioning bracket 1 and the rotating bracket 6 are both cylindrical, the rotating bracket 6 is built into the positioning bracket 1 and is rotatably connected to the positioning bracket 1, the circumferential outer wall of the positioning bracket 1 is provided with multidirectional wheels 8 through an array of steering brackets 7, the steering bracket 7 is slidably connected to the positioning bracket 1 to adjust the height of the positioning bracket 1 and the ground, and the mixing component 3 is coaxially arranged with the rotating bracket 6.

[0026] Specifically, the cleaning component 2, paving component 4 and compacting component 5 are all arranged along the diameter direction of the rotating bracket 6, but the three are in different positions and do not interfere with each other. They can all move up and down along the rotating bracket 6 to adjust their height from the ground.

[0027] Specifically, a bearing is provided between the positioning bracket 1 and the rotating bracket 6 , and the bearing is used for rotational drive connection between the two, supporting the rotating bracket 6 to rotate relative to the positioning bracket 1 .

[0028] Furthermore, a copper wire is spirally fixed on the inner wall of the positioning bracket 1, and magnets are evenly inlaid on the outer wall of the rotating bracket 6. A battery module 9 is arranged inside the rotating bracket 6, and both ends of the copper wire are connected to the positive and negative poles of the battery module 9 through wires.

[0029] Specifically, the rotating bracket 6 and the positioning bracket 1 are similar to motor structures. The outer wall of the rotating bracket 6 is evenly inlaid with magnets in an array similar to the rotor in a motor. The inner wall of the positioning bracket 1 is spirally surrounded and fixed with copper wires similar to the stator in a motor. When power is applied to the copper wires on the inner wall of the positioning bracket 1, the rotating bracket 6 rotates around the positioning bracket 1 under the action of the magnetic field.

[0030] Furthermore, the mixing assembly 3 includes a mixing pot 31 , a mixing blade 32 and an electric heating wire. The electric heating wire is arranged around the inner wall of the mixing pot 31 , and the mixing blade 32 is arranged in the inner cavity of the mixing pot 31 through a mixing shaft.

[0031] Specifically, the mixing assembly 3 further includes a mixing drive source, and an output end of the mixing drive source is drivingly connected to the mixing shaft to drive the mixing blades 32 to rotate and stir in the mixing pot 31 .

[0032] Specifically, when road repair is being carried out, the asphalt mixture is poured into the mixing pot 31. At this time, the electric heating wire is connected to the battery module 9 by a wire. At this time, the electric heating wire begins to generate heat and acts on the asphalt mixture, making it softer from a hard state, but still not completely melted, so as to facilitate discharge.

[0033] Furthermore, the cleaning component 2 includes an air press 21 and a milling blade 22. A plurality of the milling blades 22 are fixedly connected in an array along the diameter of the rotating bracket 6 and are slidably connected to the rotating bracket 6 in a vertical direction. The air press 21 is arranged on one side of the milling blade 22.

[0034] Specifically, the bottom end of the milling blade 22 is tapered to increase the pressure exerted on the ground by milling, thereby improving the milling efficiency.

[0035] Specifically, when the diseased road surface is milled, the cleaning component 2 descends along the height direction of the rotating bracket 6 until the milling blade 22 contacts the diseased road surface. At this time, the copper wire wrapped on the positioning bracket 1 is connected to the positive and negative poles of the battery module 9, and the rotating bracket 6 is driven to rotate under the action of electromagnetic induction, thereby driving the milling blade 22 to rotate, thereby milling the diseased road surface. When the milling work is completed, the diseased road surface will produce more stone chips. At this time, the air compressor 21 is connected to the battery module 9, and the air compressor 21 is driven to work to blow the stone chips out of the bottom of the rotating bracket 6.

[0036] Furthermore, the paving assembly 4 includes a storage bin 41 and a spiral distributor 42. The storage bin 41 is arranged at the lower end of the mixing pot 31. A sampler 10 is provided at the bottom end of the storage bin 41. The feed port of the storage bin 41 is connected to the discharge port of the mixing pot 31. The lower end of the spiral distributor 42 is provided with a distribution port 421.

[0037] Specifically, the sampler 10 is cylindrical, and the bottom end of the sampler 10 is serrated, so that the sampler 10 can be easily drilled into the soil.

[0038] Furthermore, the spiral feeder 42 includes a spiral feed shaft 422 , a spiral feed piece 423 , a feed bin 424 and a spiral feed driving source.

[0039] Furthermore, the output shaft of the spiral cloth driving source is driven and connected to the spiral cloth shaft 422, the spiral cloth piece 423 is formed by spirally bending an iron sheet to facilitate discharging, the spiral cloth shaft 422 is fixedly connected to the spiral cloth piece 423, and the spiral cloth shaft 422 and the spiral cloth piece 423 are placed in the inner cavity of the cloth bin 424.

[0040] Furthermore, the spiral distributor 42 is arranged along the diameter direction of the rotating bracket 6 and is slidably connected to the rotating bracket 6 in the vertical direction to change the height of the spiral distributor 42 and the ground.

[0041] Specifically, after the cleaning component 2 has finished cleaning the damaged road surface, first, the height of the spiral distributor 42 from the ground is adjusted. The distribution port 421 of the spiral distributor 42 should not be too high or too low from the ground. If it is too high, it will be difficult to control the discharge direction of the spiral distributor 42, while if it is too low, it will easily block the distribution port 421, making it difficult to discharge. Secondly, the discharge port switch at the bottom of the mixing pot 31 is opened, so that the asphalt mixture in the mixing pot 31 flows into the distribution bin 424. At this time, the spiral distribution drive source is connected to the battery module 9, so that the spiral distribution drive source drives the spiral distribution shaft 422 to rotate, and the spiral distribution sheet 423 is used to discharge the asphalt mixture from the distribution port 421 and flow to the damaged road surface.

[0042] Furthermore, the compaction assembly 5 includes a rolling shaft 51, a rolling wheel 52 and a rolling drive source. The cross-section of the rolling wheel 52 is pentagonal. Multiple rolling wheels 52 are arranged in an array and fixedly connected to the rolling shaft 51. The output end of the rolling drive source is driven and connected to the rolling shaft 51. The compaction assembly 5 is arranged along the diameter direction of the rotating bracket 6 and is slidably connected to the rotating bracket 6 in the vertical direction to change the height of the compaction assembly 5 and the ground.

[0043] Specifically, after the spiral spreader 42 paves asphalt on the diseased road surface, the height of the compacting assembly 5 and the ground is adjusted until the rolling wheel 52 contacts the ground, and the rolling drive source is connected to the battery module 9 to drive the rolling shaft 51 to rotate, thereby driving the rolling wheel 52 to rotate and hammering the asphalt mixture.

[0044] Specifically, the design of the pentagonal rolling wheel 52 utilizes the difference between its circumscribed radius and inscribed radius, as well as the potential energy of the rolling wheel's own weight, plus the kinetic energy generated by the rolling wheel's movement, to exert a certain external force on the rolled road surface. This can change the structure of each layer inside the rolling body, increase the density of the soil, and achieve a better compaction effect.

[0045] Furthermore, the rolling drive source, wind press and compaction drive source are all connected to the battery module 9 through wires.

[0046] Specifically, the rolling drive source and the mixing drive source are both servo motors. The servo motor has the following advantages in this embodiment: 1. High control accuracy: the servo motor can achieve very precise position control and speed control; 2. Fast response speed: the time from the servo motor receiving the control signal to generating a response is very short; 3. Good stability: the servo motor can remain stable during operation even when the load changes, ensuring the reliability of the system operation; 4. Large starting torque: the servo motor can provide a large torque at startup, which is conducive to acceleration and overcoming initial static friction.

[0047] Working principle: The utility model provides an integrated milling, paving and compacting device for treating small-scale shallow pavement defects, which includes a positioning bracket 1, a cleaning component 2, a mixing component 3, a paving component 4 and a compacting component 5. The cleaning component 2, the mixing component 3, the paving component 4 and the compacting component 5 are all arranged in a rotating bracket 6. The positioning bracket 1 and the rotating bracket 6 are both cylindrical. The rotating bracket 6 is built into the positioning bracket 1 and is rotatably connected to the positioning bracket 1. The circumferential outer wall of the positioning bracket 1 is provided with multidirectional wheels 8 through an array of steering brackets 7. The steering bracket 7 is slidably connected to the positioning bracket 1 to adjust the height of the positioning bracket 1 above the ground. The mixing component 3 is coaxially arranged with the rotating bracket 6. The mixing component 3 includes a mixing pot 31, a mixing blade 32 and an electric heating wire. The electric heating wire is arranged around the inner wall of the mixing pot 31, and the mixing blade 32 is arranged in the inner cavity of the mixing pot through a mixing shaft.

[0048] Specifically, maintenance personnel first place the device on the road and push the multi-directional wheels 8 to the area requiring treatment. After aligning the device's rotating bracket 6 with the top of the damage, they lock the multi-directional wheels 8 to prevent horizontal movement. Next, they adjust the height of the steering bracket 7, thereby adjusting the height of the rotating bracket 6 above the ground, so that the sampler 10 touches the ground.

[0049] At this time, the main switch is turned on to rotate the rotating bracket 6, thereby driving the sampler 10 at the bottom to drill into the road surface. After the sampler 10 drills to the required depth for disease treatment, the main switch is turned off. At this time, the core sample in the sampler 10 can be used as a sample of the disease and can be brought back to the laboratory for archiving or further research.

[0050] Next, the mixing pot 31 of the mixing assembly 3 is set to the asphalt mixture mixing temperature, and aggregate and asphalt are added to the mixing pot 31 according to the mix ratio and the requirements for the defect treatment. After completing the above steps, the main switch is turned on and the cleaning assembly 2 is activated, causing the milling blade 22 of the cleaning assembly 2 to rotate along with the rotating bracket 6. While the milling blade 22 mills the road surface, the built-in air compressor 21 of the cleaning assembly 2 is activated and blows the milled stone chips out of the bottom of the equipment through the air outlet of the air compressor 21. Because the mixing blade 32 is coaxial with the positioning bracket 1, the asphalt mixture in the mixing pot 31 has been mixed and stored in the storage bin 41 while the rotating bracket 6 drives the cleaning assembly 2 to mill the defective area.

[0051] After milling is complete, the cleaning assembly 2 is turned off, and after adjusting the height of the paving assembly 4 from the milling interface according to the loose paving coefficient, the paving assembly 4 is turned on. The asphalt mixture stored in the storage bin 41 is now spread evenly by the rotating auger 42, driving the distribution port 421 to evenly discharge the mixture, ensuring that the asphalt mixture is evenly and uniformly spread on the milling interface according to the loose paving coefficient. After the paving process is complete, the paving assembly 4 is turned off.

[0052] Finally, after adjusting the compaction assembly 5 to the desired compaction height for pavement shaping, the main switch is activated. Once the main switch is activated, the rotating bracket 6 begins to rotate, driving the rolling wheels 52 to roll the pavement. Once all of the above steps are complete, the damage in that area has been treated. The multi-directional wheels 8 can be unlocked and the equipment can be moved to another area requiring treatment.

[0053] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
