Description

Technical Field

[0001] This invention belongs to the field of asphalt testing technology, and specifically relates to an integrated Brinell viscosity measuring device and method. Background Technology

[0002] The Brinell viscometer is a precision testing device widely used in road engineering, petrochemicals, and materials science. It is suitable for measuring the absolute viscosity of Newtonian fluids and the apparent viscosity of non-Newtonian fluids. Its principle is as follows: a rotating shaft drives a rotor immersed in the liquid to be tested, rotating at a constant speed. The viscosity value is obtained by measuring the viscous torque acting on the rotor during rotation. Because different types and viscosity ranges of liquids require rotors of different specifications, frequent rotor changes are necessary during testing.

[0003] Replacing the rotor in an existing Brinell viscometer requires preheating the rotor to the temperature set for asphalt testing before testing. For example, asphalt testing requires preheating to 135°C. After testing, the operator must stop the machine, manually disassemble the fasteners connecting the rotating shaft and the rotor, and remove the used rotor. Then, a new preheated rotor is taken from the preheating device, manually aligned with the connection point on the rotating shaft, and the fasteners are manually tightened to complete the installation. The equipment is then restarted for testing. The preheated rotor is very hot, and direct contact or operation can easily cause burns. If the rotor is allowed to cool down before disassembly, heat loss will occur, resulting in poor temperature matching between the newly installed preheated rotor and the equipment, affecting the accuracy of the viscosity test data. Furthermore, existing Brinell viscometers require manual rotor cleaning after replacement, which is time-consuming and labor-intensive. Summary of the Invention

[0004] In view of the above analysis, the present invention aims to provide an integrated Brinell viscosity measuring device and method to solve one or more of the above-mentioned problems existing in the prior art.

[0005] The objective of this invention is achieved as follows:

[0006] On the one hand, an integrated Brinell viscosity measuring device is provided, comprising:

[0007] The viscometer test stage is movably connected to the main shaft and has a downwardly extending rotating shaft.

[0009] The lifting mechanism, located on one side of the rotor, can abut against the rotor and clamp it.

[0010] The disassembly robot, located on the other side of the rotor, can remove the fasteners, allowing the rotor to be separated from the rotating shaft;

[0011] The transmission mechanism, located on one side of the rotor, is used to transport the disassembled rotor out and to transport the new rotor to the bottom of the rotating shaft. The lifting mechanism is used to dock the new rotor with the rotating shaft. The disassembly robot connects the fasteners to the rotating shaft and the new rotor.

[0012] Furthermore, the disassembly manipulator includes a disassembly housing, a disassembly guide rail, a disassembly telescopic motor, a disassembly rotary motor, and a disassembly blade.

The disassembly telescopic motor can drive the disassembly rotary motor to move toward the fastener connected to the rotation axis and hold the disassembly blade against the fastener.

[0013] Furthermore, the rotor has a connecting shaft at the top, with a semi-cylindrical top end and a semi-cylindrical bottom end, allowing the connecting shaft and the rotating shaft to fit together precisely.

[0014] Furthermore, the fastener includes a fastening screw, and the connecting shaft and the rotating shaft are respectively provided with threaded holes, and the fastening screw is connected to the threaded hole.

[0015] Furthermore, the transmission mechanism includes a conveyor belt structure, a curved conveyor belt structure, and a conveyor chain structure. The conveyor chain structure is parallel to and corresponding to the conveyor belt structure. The curved conveyor belt structure is located below the rotating shaft, and the inlet end of the curved conveyor belt structure is connected to the outlet end of the conveyor belt structure. The outlet end of the curved conveyor belt structure is connected to the inlet end of the conveyor chain structure. The transmission mechanism is connected to a horizontal drive mechanism, which can drive the transmission mechanism away from the rotating shaft or move it below the rotating shaft, so that the outlet section of the conveyor belt structure is exactly below the rotating shaft.

[0016] Furthermore, the lifting mechanism includes a drive rail, a position drive mechanism, and a mechanical gripping mechanism. The drive rail has a U-shaped structure and includes two drive rails, located on the inner and outer sides of the U-shaped structure formed by the conveyor belt structure, the curved conveyor belt structure, and the conveyor chain structure, respectively. Each drive rail is equipped with a set of position drive mechanisms and mechanical gripping mechanisms. The mechanical gripping mechanism is connected to the position drive mechanism, and the position drive mechanism can drive the mechanical gripping mechanism to move on the drive rail, thereby gripping the rotor.

[0017] Furthermore, the position drive mechanism includes a conveyor belt assembly and a movable seat. The conveyor belt assembly is located on the side of the drive track, and the movable seat is connected to the side of the conveyor belt assembly away from the conveyor mechanism. The mechanical gripping mechanism includes a gripping motor, an extension member, and a gripping frame. The gripping motor is connected to the movable seat, the extension member is connected to the drive shaft of the gripping motor, and the gripping frame is connected to the extension member. The gripping frame is located above the conveyor belt structure.

[0018] Furthermore, it also includes a storage compartment. The side of the storage compartment facing the transmission mechanism is provided with an outlet and an inlet, and the opposite side is provided with an openable and closable door. The door is equipped with a first drive motor. The outlet corresponds to the inlet of the conveyor belt structure, and the inlet corresponds to the outlet of the conveyor chain structure. The storage compartment is equipped with a second drive motor on the side corresponding to the conveyor chain structure. The storage compartment is equipped with a heating module that can preheat the rotor inside the storage compartment.

[0019] Furthermore, the integrated Brinell viscosity measuring device also includes a cleaning chamber, which is mounted on the conveyor belt structure. The cleaning chamber is equipped with a rinsing nozzle and a rinsing pipe. The rinsing pipe is connected to the rinsing nozzle. The cleaning chamber is also equipped with a semi-circular arrangement of cleaning brushes, which are distributed above the conveyor belt. The rotor can be placed on the conveyor belt and enter the cleaning chamber to be rinsed by the rinsing nozzle and cleaned by the cleaning brushes.

[0020] Furthermore, the cleaning chamber includes an upper shell and a lower shell. The upper shell is located above the conveyor belt, and the lower shell is located below the conveyor belt. The upper shell and the lower shell are separated by a gap, and a liquid-separating curtain is provided at the gap. The upper shell has slots at both ends corresponding to the rotor recycling movement path.

[0021] On the other hand, this application also provides a method for measuring Brinell viscosity, using the aforementioned integrated Brinell viscosity measuring device; the measurement method includes the following steps:

[0022] Place the sample container containing the asphalt to be tested under the viscometer test platform and confirm that the new rotor has been preheated.

[0023] The viscometer test stage is moved upward along the main axis to the preset disassembly position. The lifting mechanism is activated to hold and clamp the old rotor currently connected to the rotating shaft. Then, the disassembly robot is moved to the connection position between the rotating shaft and the old rotor, and the fasteners are disassembled to separate the old rotor from the rotating shaft. The lifting mechanism places the disassembled old rotor onto the transmission mechanism, and the transmission mechanism is activated to transport the old rotor to the designated position. The transmission mechanism is then used to transport the preheated new rotor directly below the rotating shaft. The lifting mechanism clamps the new rotor and precisely aligns it with the rotating shaft. Subsequently, the disassembly robot installs the fasteners at the connection position between the rotating shaft and the new rotor, completing the fixation of the new rotor. The viscometer test stage is then moved downward along the main axis, causing the newly installed rotor to be immersed in the asphalt to be tested. Rotation detection is initiated and data is recorded.

[0024] Compared with the prior art, the integrated Brinell viscosity measuring device and method provided by the present invention can automatically replace the rotor and clean the replaced rotor when measuring asphalt viscosity. The entire process does not require manual contact with the preheated rotor, avoiding the problem of burns during manual operation. At the same time, the rotor can be disassembled and installed without cooling, ensuring that the rotor always maintains the preset preheating temperature and avoiding the impact of temperature loss on the accuracy of viscosity detection data.

[0042] A specific embodiment of the present invention, such as Figures 1 to 5 As shown, an integrated Brinell viscosity measuring device is disclosed, including a viscometer test stage 10, a rotor 12, a lifting mechanism 30, a disassembly manipulator 20, and a transmission mechanism 40. The viscometer test stage 10 is movably connected to a main shaft 72 and has a downwardly extending rotating shaft 11. The rotor 12 is detachably connected to the rotating shaft 11 via fasteners. The lifting mechanism 30 is located on one side of the rotor 12 and can abut against and clamp the rotor 12. The disassembly manipulator 20 is located on the other side of the rotor 12 and can remove the fasteners, separating the rotor 12 from the rotating shaft 11. The transmission mechanism 40 is located on one side of the rotor 12 and is used to transport the disassembled rotor 12 and a new rotor 12 below the rotating shaft 11. The lifting mechanism 30 is used to connect the new rotor 12 to the rotating shaft 11, and the disassembly manipulator 20 connects the fasteners to the rotating shaft 11 and the new rotor 12.

[0043] During measurement, the sample container 71 is placed below the viscometer test stage 10, and the viscometer test stage 10 is controlled to move downward on the main shaft 72. The rotor 12 is inserted into the sample container 71. The viscometer testing stage 10 controls the rotation of the rotating shaft 11 and records the experimental data. After the experiment, if a different rotor 12 needs to be replaced, first, the rotor 12 and the viscometer testing stage 10 are moved upwards to the disassembly position. Then, the lifting mechanism 30 is controlled to press against and clamp the rotor 12. The disassembly robot 20 is controlled to remove the fasteners. At this time, the rotor 12 will separate from the rotating shaft 11. The disassembled rotor 12 is placed on the transmission mechanism 40 by the lifting mechanism 30, which then transports the disassembled rotor 12 out. At the same time, the new rotor 12 is placed on the transmission mechanism 40 and transported to the area below the rotating shaft 11. The lifting mechanism 30 mates the new rotor 12 with the rotating shaft 11. The disassembly robot 20 connects the fasteners to the rotating shaft 11 and the new rotor 12, completing the installation of the rotor 12. The rotor 12 is preheated before installation. If the old rotor 12 is not available, the new rotor 12 can be installed directly.

[0044] In this embodiment, the viscometer test stand 10 adopts an existing structure, including a support base and a lifting adjustment mechanism. The lifting adjustment mechanism includes a lifting column, a hand-cranked screw or electric push rod, and a guide rail. The viscometer test stand 10 is driven to move up and down along the main shaft 72 by the hand-cranked screw or simple electric control, realizing the action of the rotor 12 immersing in and detaching from the asphalt to be tested. A rotary drive assembly is also provided, installed inside the viscometer test stand 10. One end is connected to a stepper motor or servo motor, and the other end extends out of the viscometer test stand 10 and is connected to the rotating shaft 11. The motor is driven by gear or belt transmission, driving the rotating shaft 11 and the rotor 12 to rotate synchronously. A built-in torque sensor is used to detect the viscous torque on the rotor 12. A simple control panel is provided on the side of the viscometer test stand 10 or it can be controlled by an external computer.

[0045] In this application, the rotor 12 is cylindrical, or the main body is cylindrical with a conical structure at the bottom. The shape of the sample container 71 is adapted to the rotor 12. The rotor 12 can enter the interior of the sample container 71, which contains asphalt. The sample container 71 is also heat-treated.

[0046] In some alternative embodiments, the disassembly manipulator 20 includes a disassembly housing 21, a disassembly guide rail 22, a disassembly telescopic motor 23, a disassembly rotary motor 24, and a disassembly blade 25. The disassembly housing 21 is connected to the bottom surface of the viscometer test stage 10. The disassembly guide rail 22 is connected to the inner top surface of the disassembly housing 21 and is horizontally positioned towards the rotation shaft 11. The housing of the disassembly rotary motor 24 is slidably connected to the disassembly guide rail 22. The disassembly telescopic motor 23 is driven to drive the disassembly rotary motor 24. The drive shaft of the disassembly rotary motor 24 is connected to the disassembly blade 25. The disassembly telescopic motor 23 can drive the disassembly rotary motor 24 to move toward the fastener connected to the rotation shaft 11 and hold the disassembly blade 25 against the fastener, which includes a fastening screw.

[0047] In this embodiment, when it is necessary to disassemble or install fasteners, the disassembly telescopic motor 23 first drives the disassembly rotary motor 24 to move, so that the disassembly blade 25 abuts against the fastening screw. Then, the disassembly rotary motor 24 starts, driving the disassembly blade 25 to rotate synchronously, thereby realizing the operation of unscrewing or screwing in the fastening screw. At the same time, the disassembly telescopic motor 23 retracts synchronously or extends to the rotating shaft 11, realizing the full automation of fastener disassembly and installation.

[0048] The disassembly tool 25 is either flat or Phillips head, and the fastening screw has a groove corresponding to the disassembly tool 25. The disassembly tool 25 can be made using a magnet.

[0049] In this embodiment, the disassembly housing 21 is fixedly connected to the viscometer test stage 10, so that the relative horizontal position of the disassembly blade 25 and the fastening screw on the rotating shaft 11 is always fixed. This ensures that the disassembly blade 25 can be accurately aligned with the screw every time the fastener is disassembled or installed, and avoids misalignment between the disassembly blade 25 and the screw due to positional deviation.

[0050] In some alternative embodiments, the rotor 12 has a connecting shaft at the top, the top end of the connecting shaft is a semi-cylindrical structure, and the bottom end of the rotating shaft 11 is also a semi-cylindrical structure, so that the connecting shaft and the rotating shaft 11 can be precisely mated together. The connecting shaft and the rotating shaft 11 are respectively provided with threaded holes, and fastening screws are connected to the threaded holes.

[0051] The top end of the connecting shaft at the top of the rotor 12 is a semi-cylindrical structure, and the bottom end of the rotating shaft 11 is a matching semi-cylindrical structure. When the rotor 12 and the rotating shaft 11 are docked, the two semi-cylindrical structures fit together and engage to achieve quick positioning, so that the connecting shaft and the preset threaded hole on the rotating shaft 11 are automatically aligned. Then, the fastening screw is screwed into the aligned threaded hole to complete the fixed connection between the rotor 12 and the rotating shaft 11.

[0052] Optionally, the fastening screws after the rotating shaft 11 is connected to the rotor 12 can be set to two, distributed vertically at intervals. In this way, a set of disassembly blades 25 and disassembly rotary motors 24 can be set to disassemble the two fastening screws respectively.

[0053] In some alternative embodiments, the transmission mechanism 40 includes a conveyor belt structure 41, a curved conveyor belt structure 42, and a conveyor chain structure 43. The conveyor chain structure 43 is parallel to and corresponding to the conveyor belt structure 41. The curved conveyor belt structure 42 is located below the rotating shaft 11, and the inlet end of the curved conveyor belt structure 42 is connected to the outlet end of the conveyor belt structure 41. The outlet end of the curved conveyor belt structure 42 is connected to the inlet end of the conveyor chain structure 43. The transmission mechanism 40 is connected to a horizontal drive mechanism, which can drive the transmission mechanism 40 away from the rotating shaft 11 or move it below the rotating shaft 11, so that the outlet section of the conveyor belt structure 41 is exactly below the rotating shaft 11.

[0054] In this embodiment, when the rotor 12 needs to be replaced, the horizontal drive mechanism drives the transmission mechanism 40 to move entirely below the rotating shaft 11. The outlet section of the conveyor belt structure 41 is located precisely below the rotating shaft 11, facilitating the placement of the old rotor 12 and the docking of the new rotor 12. When the equipment is performing testing, the horizontal drive mechanism drives the transmission mechanism 40 away from the rotating shaft 11 to avoid interfering with the lifting and lowering of the viscometer test platform 10 and its testing actions. After the old rotor 12 is disassembled, it is conveyed to the conveyor belt structure 43 via the conveyor belt structure 41 and the curved conveyor belt structure 42, and then conveyed out by the conveyor belt structure 43. The new rotor 12 is conveyed to the area below the rotating shaft 11 via the conveyor belt structure 41.

[0055] The conveyor belt structure 41, the curved conveyor belt structure 42, and the conveyor chain structure 43 all adopt existing conveyor structures. The conveyor belt structure 41 and the curved conveyor belt structure 42 both include a conveyor belt surface, rollers, and a conveyor motor. The conveyor motor drives the rollers to rotate and drives the conveyor belt surface to move. The conveyor chain structure 43 mainly includes a chain plate that supports the rotor 12, a drive motor, and a support frame.

[0056] In some optional embodiments, the lifting mechanism 30 includes a drive rail 31, a position drive mechanism, and a mechanical gripping mechanism. The drive rail 31 has a U-shaped structure and includes two drive rails, located on the inner and outer sides of the U-shaped structure formed by the conveyor belt structure 41, the curved conveyor belt structure 42, and the conveyor chain structure 43, respectively. Each drive rail 31 is provided with a set of position drive mechanisms and mechanical gripping mechanisms. The mechanical gripping mechanism is connected to the position drive mechanism and can drive the mechanical gripping mechanism to move on the drive rail 31. The mechanical gripping mechanism grips the rotor 12.

[0057] In this embodiment, the mechanical gripping mechanism can be a robotic arm, which is an existing device that can directly grip the rotor 12 and perform actions such as flipping and moving.

[0058] In some alternative embodiments, the position drive mechanism includes a conveyor belt assembly 32 and a movable seat 33. The conveyor belt assembly 32 is disposed on the side of the drive rail 31, and the movable seat 33 is connected to the side of the conveyor belt assembly 32 away from the conveyor mechanism 40. The mechanical gripping mechanism includes a gripping motor 34, an extension 35, and a gripping frame 36. The gripping motor 34 is connected to the movable seat 33, the extension 35 is connected to the drive shaft of the gripping motor 34, and the gripping frame 36 is connected to the extension 35 and is located above the conveyor belt structure 41.

[0059] In this embodiment, when installing a new rotor 12, the new rotor 12 is placed flat on the inlet end of the conveyor belt structure 41. Simultaneously, the control conveyor belt assembly 32 drives the inner movable seat 33 to move the extension 35 and the clamping frame 36 closer to the inlet end of the conveyor belt structure 41. The clamping motor 34 drives the extension 35 to rotate towards the inlet end, causing the clamping frame 36 to lie flat on the surface of the conveyor belt structure 41 before the rotor 12 is placed. Simultaneously, the outer movable seat 33 is moved closer to the middle of the conveyor belt structure 41. The clamping frame 36 on the inner movable seat 33 is located at the bottom of the cylindrical structure of the rotor 12. The other clamping frame 36 moves above the rotor 12 and contacts it. Then, the two clamping frames 36 clamp the rotor 12, while the clamping motor 34 rotates, and the conveyor belt assembly 32 drives the movable seat 33 to move away from the conveyor belt structure 41. In this way, the rotor 12 is erected. After being erected, the conveyor belt structure 41 begins to transport the rotor 12 towards the rotating shaft 11. When the rotor 12 is clamped, it remains placed on the conveyor belt structure 41 for support until it moves below the rotating shaft 11. Two clamping frames 36 connect the rotor 12 to the rotating shaft 11, while the disassembly blade 25 abuts against the fastening screw. The clamping frames 36 serve as a fixing structure, and the disassembly blade 25 applies force to install the fastening screw. When disassembling the old rotor 12, the clamping frame 36 directly clamps onto the rotor 12, and the disassembly knife 25 removes the fastening bolts. After disassembly, the clamping frame 36 and the clamping motor 34 move to place the rotor 12 vertically on the conveyor belt structure 41. At the same time, the rotor 12 is clamped and transitioned to the curved conveyor belt structure 42. Then, the force is slightly reduced so that the rotor 12 is supported on the curved conveyor belt structure 42. Since some models of rotor 12 are not easy to pass through turns when lying flat, these rotors 12 are placed vertically. After passing through the curved conveyor belt structure 42, the rotor 12 is clamped with force and transitioned to the conveyor chain structure 43. On the conveyor chain structure 43, the rotor 12 is laid flat to facilitate cleaning of the rotor 12.

[0060] In some alternative embodiments, the notch corresponding to the semi-cylindrical structure of the rotor 12 faces upwards. After the gripping frame 36 erects the rotor 12, the notch faces the direction of the rotation axis 11, and the notch on the rotation axis 11 is opposite to it. Therefore, after the rotor 12 is erected, it can directly correspond to the rotation axis 11. When gripping a new rotor 12, the gripping frame 36 located above the rotor 12 can move to the notch of the rotor 12 and fit into the notch. By controlling the gripping frame 36 to move back and forth at the notch, the semi-cylindrical structure of the rotor 12 can be made horizontal, thereby adjusting the posture of the rotor 12.

[0061] The clamping frame 36 includes a first baffle and a second baffle. The first baffle is perpendicular to the axial direction of the rotor 12, which lies flat on the conveyor belt structure 41. The second baffle is parallel to the axial direction of the rotor 12. Two of each baffle are included, forming a U-shaped structure. The second baffle protrudes from the first baffle and is slidably connected to it via a groove on the first baffle, allowing the second baffle to slide on the first baffle. The second baffle and the first baffle have sliding resistance. The rotor 12 can be positioned in the alignment space formed by the two second baffles, which is opposite to the rotation shaft 11, facilitating subsequent docking of the rotor 12. When the rotor 12 is positioned between the two second baffles, the sliding resistance is greater than the force exerted by the rotor 12 when it shakes and presses against the second baffles.

[0062] In some alternative embodiments, a three-axis slide rail module 70 is provided on the transmission mechanism 40. The three-axis slide rail module 70 is connected to the viscometer test stage 10 or an external structure. The three-axis slide rail module 70 adopts an existing structure. When the rotor 12 is docked, the three-axis slide rail module 70 can use a laser detector to detect the alignment status of the rotor 12 and the rotation axis 11, and make angle adjustments based on the three-axis slide rail module 70. Alternatively, when installing or removing the rotor 12, the transmission mechanism 40 and the moving seat 33 can be moved downward or upward to make the docking or removal of the rotor 12 more convenient. For example, when removing the rotor 12, the transmission mechanism 40 moves upward to receive and support the removed rotor 12.

[0063] In some optional embodiments, the integrated Brinell viscosity measuring device further includes a storage chamber 50. The storage chamber 50 has an outlet and an inlet on one side facing the transmission mechanism 40, and an openable and closable door 51 on the opposite side. A first push motor 52 is provided on the door 51. The outlet corresponds to the inlet of the conveyor belt structure 41, and the inlet corresponds to the outlet of the conveyor chain structure 43. A second push motor 53 is provided on the side of the storage chamber 50 corresponding to the conveyor chain structure 43. A heating module is provided inside the storage chamber 50 to preheat the rotor 12 inside the storage chamber 50.

[0064] The outlet of the storage bin 50 is higher than the conveyor belt structure 41, so that after the rotor 12 is placed in the storage bin 50, the second push motor 53 pushes the rotor 12 to the corresponding position of the outlet or places it directly in the corresponding position of the outlet, and then the first push motor 52 pushes it into the inlet end of the conveyor belt structure 41, and the rotor 12 is placed above a gripping frame 36.

[0065] The storage compartment 50 has an extension slot corresponding to the position of the conveyor belt structure 43. The conveyor belt structure 43 extends into the extension slot, allowing it to be positioned within the storage compartment 50. The second drive motor 53 is located on one side of the conveyor belt structure 43. Therefore, the conveyor belt structure 43 transmits the rotor 12 into the storage compartment 50, and the second drive motor 53 can push the rotor 12 on the conveyor belt structure 43 into the central placement area of ​​the storage compartment 50. The sealing door 51 can be opened, allowing the rotor 12 to be pre-placed at the corresponding position of the ejection port. The cylindrical structure of the rotor 12 faces the rotation shaft 11 and is placed flat during placement.

[0066] In this embodiment, the storage bin 50, the conveyor belt structure 41, the curved conveyor belt structure 42, and the conveyor chain structure 43 can all be connected to a support structure. The support structure is connected to the three-axis slide rail module 70, so that the storage bin 50, the conveyor belt structure 41, the curved conveyor belt structure 42, and the conveyor chain structure 43 can move together.

[0067] The storage compartment 50 is also equipped with a heating structure, such as a heating pipe that blows hot air into the heating pipe to preheat the rotor 12, or a heating wire that can be installed for direct preheating, while simultaneously drying the rinsed rotor 12.

[0068] In some alternative embodiments, the integrated Brinell viscosity measuring device also includes a cleaning chamber fitted on the conveyor belt structure 43. The cleaning chamber is equipped with a rinsing nozzle and a rinsing pipe, the rinsing pipe being connected to the rinsing nozzle. The cleaning chamber is also equipped with a fan-shaped arrangement of cleaning brushes distributed above the conveyor belt. The rotor 12 can be placed on the conveyor belt and enter the cleaning chamber to be rinsed by the rinsing nozzle and cleaned by the cleaning brushes.

[0069] The cleaning chamber is mounted on the conveyor belt structure 43, allowing the conveyor belt structure 43 to drive the horizontally lying rotor 12 directly into the cleaning chamber. One end of the rinsing pipe is connected to an external solvent supply system, and the other end is connected to the rinsing nozzle inside the cleaning chamber, which can continuously supply cleaning solvent, such as citrus terpene solvent, to the nozzle. The cleaning brushes inside the cleaning chamber are arranged in a fan shape above the conveyor belt, and the brush end faces can fit against the cylindrical surface of the horizontally lying rotor 12. After the old rotor 12 is transported to the conveyor belt structure 43 and laid flat, the conveyor belt drives the rotor 12 into the cleaning chamber at a constant speed. At this time, the rinsing nozzle is activated, and the cleaning solvent is sprayed evenly onto the upward-facing surface of the rotor 12 to dissolve the residual asphalt slurry on the rotor 12. At the same time, the rotor 12 moves with the conveyor belt, and the semi-circular cleaning brush generates relative friction with the upward-facing surface of the rotor 12 to wipe away stubborn residues that have not been completely removed after spraying. After the first side cleaning is completed, the conveyor belt rotates, and the clamping frame 36 on one side moves synchronously with the rotor 12. After reaching the initial entry position, it clamps the rotor 12 and drives it to flip over, so that the originally downward-facing surface of the rotor 12 is facing upward. Then the rinsing nozzle is activated again to spray, and the cleaning brush wipes the surface of the flipped rotor 12 simultaneously to achieve full surface cleaning of the rotor 12. After cleaning is completed, the conveyor belt structure 43 continues to drive the rotor 12 out of the cleaning chamber.

[0070] The cleaning chamber includes an upper shell 60 and a lower shell 61. The upper shell 60 is located above the conveyor belt, and the lower shell 61 is located below the conveyor belt. The upper shell 60 and the lower shell 61 are spaced apart, and a liquid-blocking curtain is provided at the space. The upper shell 60 has slots at both ends of the rotor 12’s recovery movement path.

[0071] The lower shell 61 can collect cleaning waste liquid in a centralized manner, which facilitates subsequent recycling and treatment, and improves the utilization rate and environmental friendliness of the solvent. The liquid slugging curtain further prevents solvent splashing. A liquid slugging curtain is also provided at the trough opening. A waterproof shell can be added outside the upper shell 60 and the lower shell 61 to increase the liquid separation distance. The gap between the upper shell 60 and the lower shell 61 allows the moving seat 33 to move, so that the clamping frame 36 can also perform corresponding actions when the rotor 12 is cleaning.

[0072] This application adopts a design where the rotor 12 is placed horizontally, which has the following advantages compared with the prior art method of directly connecting the rotor shaft 11 vertically: When the rotor 12 is placed horizontally in the storage compartment 50 of this application, the center of gravity of the rotor 12 is lower in the horizontal state, making storage and transfer more stable and less prone to tipping and damage; while in the prior art, the rotor 12 is placed vertically, which is prone to tilting and collision due to equipment vibration, increasing the risk of damage to the rotor 12. At the same time, the storage compartment 50 needs to be designed with a higher vertical dimension, resulting in a larger overall volume.

[0073] In this application, the rotor 12 enters the cleaning chamber lying flat, allowing the spray nozzles to cover the upward-facing surface of the rotor 12 from all directions. Combined with a semi-circular brush for close-fitting wiping, and after flipping, the other side of the surface can be cleaned, achieving a thorough cleaning of the entire surface of the rotor 12 without any blind spots. In existing technologies, when the rotor 12 is cleaned vertically, the bottom area is difficult to reach with the spray and brushes, leading to the accumulation of residual asphalt. This results in lower cleaning efficiency and cleanliness compared to the horizontally placed cleaning mode. The horizontally placed rotor 12 has a low center of gravity, making it less prone to swaying or tipping during transport on conveyor belts, curved conveyor belts, and conveyor chains. The overall equipment extends horizontally and has a lower vertical height, making it more suitable for installations in laboratories with limited space.

[0074] This embodiment also provides a method for measuring Brinell viscosity, using an integrated Brinell viscosity measuring device; the measurement method includes the following steps:

[0075] Place the sample container 71 containing the asphalt to be tested under the viscometer test platform 10, and confirm that the new rotor 12 in the storage chamber 50 has been preheated.

[0076] The viscometer test stage 10 is controlled to move upward along the main shaft 72 to the preset disassembly position. The lifting mechanism 30 is activated to hold and clamp the old rotor 12 currently connected to the rotating shaft 11. Then, the disassembly robot 20 is controlled to move to the connection position between the rotating shaft 11 and the old rotor 12. The disassembly blade 25 of the disassembly robot 20 performs a disassembly operation on the fasteners (fastening screws) to separate the old rotor 12 from the rotating shaft 11.

[0077] The lifting mechanism 30 places the disassembled old rotor 12 onto the transmission mechanism 40, controls the transmission mechanism 40 to start, and transports the old rotor 12 to the designated position (or to the cleaning chamber for cleaning).

[0078] The control transmission mechanism 40 transports the preheated new rotor 12 from the storage compartment 50 to directly below the rotating shaft 11. The lifting mechanism 30 clamps the new rotor 12 and precisely aligns the semi-cylindrical structure at the top of its connecting shaft with the bottom of the rotating shaft 11. Then, the control disassembly robot 20 installs fasteners at the connection point between the rotating shaft 11 and the new rotor 12, thus completing the fixation of the new rotor 12.

[0079] The viscometer test stand 10 is controlled to move downward along the main shaft 72, which drives the newly installed rotor 12 to be immersed in the asphalt to be tested in the sample container 71. The rotation drive component inside the viscometer test stand 10 is started to drive the rotor 12 to rotate at a constant speed. The built-in torque sensor detects the viscous torque on the rotor 12, and the viscosity value of the asphalt to be tested is calculated based on the detected data. The measurement is completed and the data is recorded.

[0080] The above specific embodiments further illustrate the purpose, technical solution and beneficial effects of this application. It should be understood that the above are only specific embodiments of this application and are not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
