Description

Technical Field

[0001] This application belongs to the field of asphalt testing technology, specifically relating to an asphalt mixture rut sample forming device. Background Technology

[0002] In asphalt testing, cleaning the compaction surface of the asphalt mixture rutting sample forming device is crucial. After each compaction operation, a large amount of asphalt adheres to the compaction surface, which urgently needs to be cleaned to ensure the accuracy and reliability of subsequent tests.

[0003] In the past, mechanical removal was a common method. Taking power tools with wire brushes as an example, their working principle is to scrape the adhering asphalt using a high-speed rotating wire brush. However, this method has serious drawbacks. Because the wire brush is hard and has a large impact force at high speed, it easily causes mechanical damage to the compacted surface during contact. Even minor scratches or wear can disrupt the original smoothness of the compacted surface. The smoothness of the compacted surface directly affects the molding accuracy of subsequent rutted sample specimens. Once the smoothness decreases, the pressure distribution will be uneven during the molding of new specimens, leading to inconsistent internal structures and ultimately causing deviations in the dimensional accuracy and internal compaction of the specimens, greatly affecting the accuracy of asphalt mixture performance testing.

[0004] Let's look at the manual cleaning method using chisels and scrapers. When faced with large areas and thick layers of asphalt, the limitations of manual operation become glaringly apparent. Operators need to expend a great deal of time and energy to remove the asphalt point by point and piece by piece, making this cleaning process extremely inefficient.

[0005] Traditional mechanical cleaning methods struggle to strike a balance between efficient cleaning and non-destructive equipment when cleaning the compacted surface of asphalt mixture rutted sample forming devices. Utility Model Content

[0006] To address the shortcomings of the existing technology, this application provides an asphalt mixture rutting sample forming device. Through the design of a heating element in the compaction wheel, the compaction surface can be heated and softened before cleaning the asphalt. Then, the cleaning component is activated to clean the compaction surface. Combining the asphalt softening function and external cleaning, efficient cleaning of the compaction surface is achieved. Furthermore, with the addition of the heating function, a gentle cleaning method can be adopted, avoiding the possibility of device damage. It can simultaneously ensure efficient cleaning and stable device structure, thereby maintaining stable performance and ensuring long-term reliable operation.

[0007] The technical effects to be achieved in this application are realized through the following aspects:

[0008] This application provides an asphalt mixture rutting sample forming device, including a roller mechanism, wherein the roller mechanism includes a transmission component and a roller assembly, and the transmission component and the roller assembly are drivenly connected;

[0009] The grinding wheel assembly includes:

[0010] A compaction roller includes a roller body, a compaction surface, guide rails, and a heating element. The compaction surface is located at the lower end of the roller body, the guide rails are located on both sides of the roller body, and the heating element is located within the roller body and is used to heat the compaction surface.

[0011] The cleaning component includes a drive unit, a slider, and a cleaning unit. The drive unit is driven to the slider, the slider is slidably connected to the guide rail, one end of the cleaning unit is connected to the slider, and the other end of the cleaning unit is in contact with the rolling surface for cleaning the rolling surface.

[0012] In some implementations, the surface formed by the guide rails and the surface formed by the rolling surface are parallel.

[0013] In some implementations, the cleaning unit includes:

[0014] The cleaning section contacts the rolling surface; and

[0015] The connecting bracket has one end connected to the slider and the other end detachably and fixedly connected to the cleaning part.

[0016] In some implementations, the cleaning unit includes a body, a scraper, and a wiping component. The body is provided with a slot, and the scraper and the wiping component are both embedded in the slot.

[0017] In some implementations, the cleaning unit further includes limiting strips, which are symmetrically disposed at both ends of the body;

[0018] The connecting frame is provided with a limiting groove that is adapted to fit the limiting strip.

[0019] In some implementations, the scraper is a silicone scraper.

[0020] In some implementations, the cleaning component further includes a locking element, the slider has a threaded hole adapted to the locking element, the connecting bracket has a connecting hole corresponding to the locking element, the locking element passes through the connecting hole and is connected to the threaded hole.

[0021] In some implementations, the inner surface of the connecting hole is provided with threads that are compatible with the locking element.

[0022] In some implementations, the back of the compaction wheel is provided with a storage groove opposite the compaction surface, the storage groove being used to place the cleaning component.

[0023] In some implementations, the wiping element is a sponge wiping element.

[0024] In summary, this application has at least the following advantages:

[0025] The asphalt mixture rutting sample forming device provided in this application first heats the compacted surface using a heating element during the cleaning process, thereby softening the asphalt on the compacted surface. Once softened to a certain degree, the cleaning component is activated. A cleaning unit, which slides along a guide rail, contacts the compacted surface and cleans it repeatedly, thus removing the softened asphalt. By combining the asphalt softening function with external cleaning, the convenience of cleaning the compacted surface is improved, achieving efficient cleaning. Furthermore, the heating function allows for a gentler cleaning method, avoiding potential damage to the device. This device offers the advantages of efficiently cleaning the compacted surface while avoiding damage, thereby maintaining stable performance and ensuring long-term reliable operation.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0036] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0037] Example 1:

[0038] Please see the appendix Figure 1-2 This application proposes an asphalt mixture rut sample forming device including a roller mechanism. The roller mechanism includes a transmission component 1 and a roller assembly 2, which are driven and connected. The roller assembly 2 includes a compaction roller 21 and a cleaning component 22. The compaction roller 21 has a compaction surface 212 at the lower end of its body 2241, and guide rails 213 are installed on both sides. The body 2241 has a built-in heating element 214 for heating the compaction surface 212. The cleaning component 22 includes a drive component 223, a slider 221, and a cleaning unit 222. The drive component 223 drives the slider 221 to move along the guide rails 213. One end of the cleaning unit 222 is connected to the slider 221, and the other end contacts the compaction surface 212 to perform cleaning operations.

[0039] Among them, the transmission component 1 refers to the power transmission device, which can be implemented by a gear set or a pulley mechanism, and is used to convert the rotational motion output by the power source into the rolling motion of the rolling wheel 21.

[0040] The roller assembly 2 refers to the unit that performs the rolling function. Specifically, it can be realized by combining a metal wheel body 211 with a support shaft. Its rolling surface 212 is treated with surface hardening to improve wear resistance.

[0041] The guide rail 213 refers to the guiding structure that constrains the motion path. Specifically, it can be implemented in the form of a T-slot or a dovetail groove, and is used to limit the movement of the slider 221 in a direction parallel to the rolling surface 212.

[0042] The heating element 214 refers to the temperature control element, which can be implemented by resistance wire or electromagnetic heating module. Its function is to raise the temperature of the compaction surface 212 through heat conduction, thereby softening the attached asphalt.

[0043] The cleaning unit 222 refers to the surface cleaning device, which can be implemented by a combination of elastic scraper and adsorbent material. When it contacts the rolling surface 212, the contact pressure is adjusted by deformation.

[0044] Specifically, after the transmission assembly 1 drives the roller assembly 2 to perform the compaction operation, the heating element 214 preheats the compaction surface 212, softening the residual asphalt. When the drive component 223 drives the slider 221 to move along the guide rail 213, the cleaning unit 222 moves synchronously with the slider 221. When the cleaning unit 222 contacts the compaction surface 212, it adaptively adjusts the contact pressure through elastic deformation, effectively scraping off the softened asphalt while avoiding rigid impact damage to the surface. The continuous movement of the drive component 223 enables the cleaning unit 222 to complete a full-coverage cleaning of the compaction surface 212.

[0045] This embodiment significantly reduces the mechanical impact of cleaning operations by combining heating and softening with directional cleaning. The guide rail 213 constraint mechanism ensures that the cleaning unit 222 moves along a preset path, eliminating the risk of trajectory deviation. Continuous cleaning can be achieved through automated drive, reducing manual intervention.

[0046] The above technical solution achieves efficient cleaning of asphalt residue and effective protection of the flatness of the compacted surface 212. The heating element 214 softens the asphalt to reduce cleaning resistance, the guide rail 213 constrains the cleaning path to prevent trajectory deviation, and the elastic cleaning unit 222 adapts to contact pressure to prevent surface damage. This device simultaneously completes compaction and cleaning actions in a single operation, reducing downtime and ensuring uniform pressure distribution during rut sample forming.

[0047] In some embodiments, the surface formed by the guide rail 213 and the surface formed by the rolling surface 212 are parallel. With this arrangement, since the guide rail 213 and the rolling surface 212 remain parallel, the movement trajectory of the cleaning unit 222 always conforms to the shape of the rolling surface 212, avoiding local pressure concentration caused by lateral displacement and achieving comprehensive cleaning.

[0048] The surface formed by the guide rail 213 refers to the reference plane formed by the guide structure set on both sides of the body 2241 of the rolling wheel 21. Specifically, it can be realized by using a guide rail 213 formed by high-precision machining, which is used to constrain the movement trajectory of the cleaning component 22.

[0049] The surface formed by the compaction surface 212 refers to the working plane where the lower end of the compaction wheel 21 body 2241 contacts the asphalt mixture. Specifically, it can be achieved by using a metal surface that has been ground, and its flatness error can be controlled within 0.05 mm.

[0050] Specifically, the guide rail 213 and the compaction surface 212 form two sets of parallel planes in spatial layout. When the cleaning component 22 slides along the guide rail 213 via the slider 221, a constant contact angle is formed between the cleaning unit 222 and the compaction surface 212. Since the parallelism error between the plane of the guide rail 213 and the plane of the compaction surface 212 is limited to a preset range, the uniformity of the normal pressure distribution generated by the cleaning unit 222 during movement is precisely controlled. Through this spatial constraint, the cleaning unit 222 will not experience sudden pressure changes in local areas due to the tilt of the guide rail 213 when moving laterally, thus avoiding asymmetrical wear on the compaction surface 212. Simultaneously, the parallel layout allows the cleaning unit 222 to completely cover the effective working area of ​​the compaction surface 212, eliminating cleaning blind spots caused by trajectory deviation. This ensures that the force exerted by the cleaning unit 222 on the compaction surface 212 is always perpendicular to the surface and evenly distributed, efficiently removing asphalt residue while avoiding mechanical damage to the compaction surface 212.

[0051] In some embodiments, please refer to the appendix. Figure 2 The cleaning unit 222 includes a cleaning part 224 and a connecting frame 225 that is detachably and fixedly connected to the cleaning part 224. One end of the connecting frame 225 is connected to the slider 221.

[0052] The cleaning unit 224 refers to the cleaning function component that is in direct contact with the rolling surface 212. Specifically, it can be implemented by a combination structure of scraper 2242 and wiping component 2243. The component is fixed by the fitting method of slot 2244 and is used to perform operations with different cleaning intensities.

[0053] The detachable fixed connection refers to a mechanical connection method that allows the cleaning unit 224 to be separated from the connecting frame 225.

[0054] Specifically, the cleaning unit 224 directly acts on the compacted surface 212 to remove asphalt residue. The connecting frame 225 is fixedly connected to the slider 221, and its other end is detachably connected to the cleaning unit 224. When the cleaning unit 224 needs to be replaced, it is detached from the connecting frame 225. A new cleaning unit 224 is then installed and fixedly connected to the connecting frame 225. This structure allows for maintenance of the cleaning unit 224 by replacing only worn parts, and also allows for the selection of cleaning units 224 made of different materials depending on the degree of asphalt adhesion.

[0055] The aforementioned split design separates the cleaning unit 224 from the connecting frame 225, allowing for independent replacement of the cleaning unit 224 via a detachable connection structure, significantly reducing maintenance time. It also enables quick replacement of the cleaning unit 224 and flexible compatibility with various cleaning tools, improving the convenience of maintenance operations while ensuring cleaning effectiveness.

[0056] In some embodiments, please refer to the appendix. Figures 3-4 The cleaning unit 224 includes a body 2241, a scraper 2242 and a wiping component 2243. The body 2241 is provided with a slot 2244, and the scraper 2242 and the wiping component 2243 are both connected to the slot 2244.

[0057] The scraper 2242 refers to a strip-shaped structure with elastic edges. Preferably, the scraper 2242 is a silicone scraper 2242. Specifically, it can be achieved by compression molding of vulcanized silicone rubber, with a Shore hardness range of 40A to 70A. When this material comes into contact with the rolling surface 212, it absorbs mechanical stress through elastic deformation, avoiding scratch damage to the metal surface.

[0058] Specifically, the silicone scraper 2242 forms a close contact with the rolling surface 212 through its own softness and resilience. During the cleaning process, the asphalt residue adhering to the rolling surface 212 is peeled off by the shear force applied by the edge of the scraper 2242, while the elastic deformation of the silicone material under pressure ensures a uniform distribution of contact pressure. This effectively removes asphalt residue while maintaining the original flatness of the metal rolling surface 212, ensuring the uniformity of pressure distribution during subsequent sample molding, thereby improving the accuracy of rutting test data.

[0059] The wiping component 2243 is a sponge wiping component 2243. Specifically, it can be made of a high-molecular polymer foam material, which has an interconnected pore structure inside. The sponge material has softness and deformation recovery ability. When it comes into contact with the rolling surface 212, it can conform to the surface contour through elastic deformation. During the wiping process, it uses its pores to adsorb asphalt particles, avoiding surface damage caused by hard friction.

[0060] Specifically, after the compaction operation is completed, the drive component 223 drives the slider 221 to slide along the guide rail 213, keeping the sponge wiping component 2243 on the connecting frame 225 in contact with the compaction surface 212. During the sliding process, the sponge wiping component 2243 generates uniform contact pressure with the compaction surface 212 through elastic compression, adsorbs residual asphalt particles through surface pores, and simultaneously peels off loosely attached asphalt through reciprocating wiping action. Because the sponge material itself is soft, it does not exert rigid impact force on the compaction surface 212 during contact, thereby avoiding scratches or wear and maintaining the original flatness of the compaction surface 212. After cleaning, the sponge wiping component 2243 can be disassembled and replaced or washed for reuse.

[0061] In this embodiment, the cleaning unit 224 carries the scraper 2242 and the wiping component 2243 via the body 2241. Both are embedded in the slots 2244 on both sides of the body 2241, forming a replaceable module. When the drive unit 223 moves the slider 221 along the guide rail 213, the scraper 2242 preferentially contacts the rolling surface 212, using the contact pressure generated by elastic deformation to scrape off the adhering material. Subsequently, the wiping component 2243 sweeps across the rolling surface 212 in a parallel contact manner, adsorbing residual particles through the pores. The independent interlocking structure of the scraper 2242 and the wiping component 2243 allows for individual replacement according to the degree of wear. For example, when the edge of the scraper 2242 is deformed, only that component can be replaced without affecting the function of the wiping component 2243.

[0062] Through a modular design that separates scraping and cleaning, coarse and fine cleaning can be performed in a single cleaning cycle. This avoids surface damage caused by excessive friction from a single tool and improves cleaning efficiency through phased cleaning. Residue is removed layer by layer, and the rolled surface 212 remains in its original flat state after cleaning. At the same time, maintenance costs are effectively controlled through the replaceable parts design.

[0063] In some embodiments, please refer to the appendix. Figure 5 The cleaning unit 224 also includes a limiting strip 2245, which is symmetrically arranged at both ends of the main body 2241; the connecting frame 225 is provided with a limiting groove 2251 that is adapted to fit the limiting strip 2245.

[0064] The limiting strip 2245 refers to the elongated protrusions at both ends of the body 2241 of the cleaning section 224, which can be made of metal or rigid plastic. The limiting groove 2251 refers to the groove structure inside the connecting frame 225 that matches the limiting strip 2245, which can be in the form of a U-shaped groove or a rectangular groove, and is used to constrain the displacement of the cleaning section.

[0065] Specifically, the cleaning unit body 2241 is fixed by being embedded in the limiting groove 2251 via the limiting strip 2245. When it is necessary to switch cleaning elements, the cleaning unit is lifted vertically upwards to disengage from the double limiting structure, rotated 180 degrees, and then re-embedded into the groove. The symmetrical arrangement of the limiting strip 2245 forces the correct installation orientation to be maintained during operation, and the tight fit between the limiting strip 2245 and the limiting groove 2251 prevents the cleaning unit from twisting or shifting during operation.

[0066] This embodiment achieves positioning through the cooperation of the limiting strip 2245 and the limiting groove 2251, allowing for rapid flipping and switching while maintaining stability, reducing operation time to one-quarter of the original method. Furthermore, the symmetrical limiting structure of this solution physically eliminates the possibility of reverse installation.

[0067] Through the above-described design, this application enables rapid switching between the scraping and wiping surfaces of the cleaning unit 224. Component disassembly and orientation adjustment can be completed without tool assistance during operation. The limiting structure maintains component stability while ensuring accurate installation each time through physical constraints.

[0068] Example 2:

[0069] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 6 The cleaning component 22 in this embodiment also includes a locking component 226. The slider 221 is provided with a threaded hole that matches the locking component 226. The connecting bracket 225 is provided with a connecting hole 2252 corresponding to the locking component 226. The locking component 226 passes through the connecting hole 2252 and is connected to the threaded hole.

[0070] The locking element 226 refers to the fastening element used to fix the connecting bracket 225 and the slider 221. Specifically, it can be implemented using a bolt with external threads, the diameter of which can match the inner diameter of the threaded hole to achieve axial locking. The threaded hole refers to the internal threaded hole structure opened on the slider 221, specifically machined with M8 or M10 standard thread specifications, used to form a helical pair with the locking element 226. The connecting hole 2252 refers to the axial through hole passing through the connecting bracket 225. Specifically, it can be set as a smooth hole or an internal threaded hole that mates with the external thread of the locking element 226, allowing the locking element 226 to pass through and extend into the threaded hole.

[0071] Specifically, when it is necessary to store the cleaning component 22, the locking component 226 can be rotated to disengage it from the engaged state. At this time, the constraint between the connecting frame 225 and the slider 221 is released, that is, the cleaning unit 222 can be taken out and placed in the storage slot 215 as a whole to avoid the cleaning component 22 from contacting the rolling surface 212 and affecting subsequent operations.

[0072] This solution utilizes the self-locking effect generated by the threaded connection to overcome the impact load caused by vibration, ensuring the positional stability of the cleaning unit 222 during simplified storage or operation. For example, the threaded connection structure provides more than three times the vibration resistance of the traditional pin structure.

[0073] Through the above-described design, this application achieves reliable storage of the cleaning unit 222 in its non-working state, preventing it from interfering with the working path of the compaction wheel 21. The threaded locking structure enables the cleaning unit 222 to have a dual-state switching function, significantly reducing the manual effort required to adjust the position of the cleaning component 22 while ensuring the continuity of the compaction operation. For example, the operator only needs to rotate the locking component 226 to complete the state switching, and the entire process takes no more than 10 seconds.

[0074] Preferably, the inner surface of the connecting hole 2252 is provided with threads adapted to the locking member 226. When the device vibrates during operation, the bolts are prone to axial loosening, causing displacement of the connecting bracket 225. The axial locking force is converted into radial constraint force through thread engagement, and the helical structure of the thread can maintain the locking state even in the presence of vibration. This effectively eliminates the risk of displacement of the cleaning unit 222 due to locking failure during operation, ensuring that the cleaning part 224 and the rolling surface 212 maintain continuous and stable contact pressure, preventing secondary damage to the rolling surface 212 caused by component shaking during cleaning, and reducing the maintenance frequency caused by loose connections.

[0075] Example 3:

[0076] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 7 In this embodiment, the rolling wheel 21 is provided with a storage groove 215 facing away from the rolling surface 212. The storage groove 215 is used to place the cleaning component 22.

[0077] The storage slot 215 refers to the receiving structure set on the back of the rolling wheel 21. Specifically, it can be implemented by a groove or a snap-fit ​​structure. Its position is opposite to the rolling surface 212 to avoid occupying the working area. This structure utilizes the idle space of the rolling wheel 21 body 2241 to integrate the storage position of the cleaning component 22 with the equipment body 2241.

[0078] The storage of cleaning component 22 refers to storing the cleaning unit 222 in the storage slot 215. Specifically, it can be fixed by buckle, magnetic attraction or limiting protrusion to prevent the cleaning component 22 from shaking and falling off when the equipment is running.

[0079] Specifically, a groove structure is provided on the side of the rolling roller 21 facing away from the rolling surface 212, with the groove opening direction opposite to that of the rolling surface 212. The cleaning unit 222 is removed and placed into the storage slot 215 when not in operation, and is fixed by the structure of the storage slot 215. Since the storage slot 215 is located on the back of the rolling roller 21, the high temperature generated by the rolling surface 212 during operation will not be directly conducted to the cleaning component 22, avoiding heat damage. The depth of the storage slot 215 can be set slightly greater than the thickness of the cleaning unit 222, so that the surface of the cleaning unit 222 is flush with the back of the rolling roller 21 after it is fully embedded, avoiding interference during equipment operation.

[0080] In this embodiment, the storage slot 215 is integrated into the rolling wheel 21. The cleaning component 22 moves synchronously with the equipment, requiring no additional storage space. When the equipment is stopped, it can be directly fixed in its original position, avoiding mixing with other tools and preventing loss or damage caused by the external environment. At the same time, it reduces the number of steps for operators to access the cleaning component 22 and improves the continuity of equipment operation.
