Description

Technical Field

[0001] The utility model relates to the technical field of asphalt stability detection, in particular to a rubber asphalt separation sampling device. Background Art

[0002] Rubber asphalt is a modified asphalt binder, also known as polymer-modified asphalt. It is widely used in highway construction both domestically and internationally. Polymers and asphalt differ significantly in their chemical structure and physical properties, such as density, viscosity, molecular weight distribution, polarity, and solubility parameters, making them thermodynamically incompatible. This incompatibility leads to spontaneous coagulation and segregation of polymers within the matrix asphalt. This occurs when polymer particles redistribute within the asphalt, forming an uneven mixture. This severely impacts the performance of rubber asphalt, such as reducing the pavement's resistance to aging and shortening its service life. Therefore, the storage stability of polymer-modified asphalt is a key issue that must be addressed in both scientific research and actual production.

[0003] Currently, the storage stability of modified asphalt is primarily evaluated using a segregation test. This involves placing the modified asphalt in a test tube and exposing it to high temperature for a period of time. Samples are then taken from the top and bottom of the tube (or from the top, middle, and bottom). The difference in softening points is then measured to evaluate the degree of segregation. However, traditional segregation tests typically require manual sampling using a pipette. This is highly inconvenient due to the operator's skill level and physical condition, as well as the potential for burns when sampling at high temperatures. Utility Model Content

[0004] The purpose of the utility model is to provide a rubber asphalt separation sampling device to solve the problem of inconvenient operation in manually extracting modified asphalt in traditional separation tests.

[0005] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0006] A rubber asphalt separation and sampling device comprises: an isolation test tube, a feed pipe and a telescopic assembly, wherein the telescopic assembly is mounted on the isolation test tube, and at least a portion of the telescopic assembly is located within the isolation test tube, and the portion of the telescopic assembly located within the isolation test tube can be telescoped along the height direction of the isolation test tube; one end of the feed pipe is located within the isolation test tube and is used to absorb the rubber asphalt within the isolation test tube, and one end of the feed pipe is connected to the portion of the telescopic assembly located within the isolation test tube, so that one end of the feed pipe can absorb rubber asphalt at different heights along the height direction of the isolation test tube; a sample cup, wherein the sample cup is located at the other end of the feed pipe and is used to receive the rubber asphalt absorbed by the feed pipe.

[0007] Based on the above technical means, the present invention achieves automated or semi-automated sampling through the integration of a telescopic assembly and a delivery tube. The operator simply manipulates the telescopic assembly to control the delivery tube's vertical movement within the separation tube, easily obtaining rubber asphalt samples at varying heights. This mechanized operation reduces human interference. Furthermore, the operator does not need to come into direct contact with the hot rubber asphalt, thereby reducing safety risks and protecting the operator.

[0008] Furthermore, it also includes a support, the sample cup is installed on the support, and the other end of the feed pipe is mounted on the support and is located above the sample cup.

[0009] According to the above technical means, the support provides a stable support platform for the sample cup and the feed pipe, preventing sample splashing or contamination caused by shaking or instability of the equipment during the sampling process, and helping to maintain the cleanliness of the sampling environment and the purity of the sample.

[0010] Furthermore, it also includes a turntable, which is rotatably mounted on the support and is located below the other end of the feed pipe; there are multiple sample cups, each of which is mounted on the turntable, and the multiple sample cups are evenly distributed along the rotation direction of the turntable, and the rotation of the turntable can drive each of the sample cups to move directly below the sample cup.

[0011] Based on the aforementioned technical means, the introduction of a turntable enables automated movement of the sample cups. Operators simply control the rotation of the turntable to sequentially move different sample cups directly under the feed pipe, eliminating the need to manually change or move the sample cups, significantly improving sampling efficiency. The turntable's design ensures that each sample cup is accurately positioned directly under the feed pipe, avoiding sampling errors caused by positional deviations. Multiple sample cups are evenly distributed along the turntable's rotational direction, facilitating uniform sampling of rubber asphalt samples at varying heights or locations, enhancing sample representativeness and accuracy.

[0012] Furthermore, it also includes a plurality of cup sleeves, each of which is fixed on the turntable, and the plurality of cup sleeves are evenly distributed along the rotation direction of the turntable; each of the sample cups is installed on each of the cup sleeves.

[0013] The cup sleeve provides additional support for the sample cup, preventing it from shaking or tilting during turntable rotation or sampling, thereby ensuring accurate and safe sampling. When the turntable rotates, the cup sleeve absorbs some of the impact, reducing direct impact on the sample cup and the sample inside, and preventing sample splashing or contamination.

[0014] Furthermore, it also includes a turntable drive assembly, which is connected to the turntable and can drive the turntable to rotate.

[0015] The turntable drive assembly, based on these technical measures, enables automated rotation of the turntable, eliminating the need for manual operation and significantly improving the automation of the sampling process. Precise control of the turntable drive assembly allows for rapid movement of different sample cups to the sampling position, reducing waiting time and improving sampling efficiency.

[0016] Furthermore, the turntable drive assembly includes a handwheel and a drive gear, the handwheel is coaxially connected to the drive gear, and the handwheel can drive the drive gear to rotate; a rack is formed on the outer edge of the turntable, and the rack is engaged with the drive gear, so that the turntable drive assembly can drive the turntable to rotate.

[0017] According to the above technical means, the handwheel and the drive gear are coaxially connected together by some means (such as key connection, spline connection or tight fit, etc.) to ensure that they can rotate synchronously. When the operator turns the handwheel, its rotational motion is transmitted to the drive gear through the coaxial connection, causing the drive gear to also start to rotate. The outer edge of the turntable is designed with a rack. The rack is a linear gear whose teeth can mesh with the teeth of the drive gear. When the drive gear rotates under the drive of the handwheel, its teeth mesh with the rack on the turntable, thereby converting the rotational motion of the drive gear into the linear (or circular) motion of the turntable. Since the rack is fixed to the turntable, the direction of rotation of the turntable is consistent with the direction of rotation of the drive gear.

[0018] Furthermore, a rotating shaft is formed on one side of the turntable close to the support, and the rotating shaft is located at the rotation center of the turntable; a groove is formed on the support, and the rotating shaft is installed in the groove.

[0019] According to the above technical means, the rotating shaft is located at the rotation center of the turntable, ensuring that the turntable can rotate smoothly and evenly. The shape and size of the groove should match the rotating shaft to ensure that the rotating shaft can be tightly and stably installed in the groove, thereby reducing friction and shaking during rotation and improving rotation accuracy and stability.

[0020] Furthermore, the depth of the groove is the same as the length of the rotating shaft.

[0021] With this technology, the depth of the groove perfectly matches the length of the shaft, allowing the shaft to fit completely within the groove, creating a tight fit. This reduces wobble and vibration caused by excessive clearance, thereby enhancing the stability of the turntable during rotation. This tight fit also ensures the shaft's position within the groove is more secure, reducing uneven rotation caused by offset or tilt.

[0022] Furthermore, it also includes a suction pump, which is installed on the material delivery pipe.

[0023] The suction pump, based on the aforementioned technology, can generate negative or positive pressure to automatically draw rubber asphalt from the separation tube, reducing manual intervention and improving the efficiency and safety of the sampling process. The drawn rubber asphalt is then transported through the delivery pipe to the sample cup on the turntable.

[0024] Furthermore, the telescopic component is an electric push rod, which includes a push rod and a drive motor, and the push rod is driven and connected to the drive motor; the drive motor is installed at the top of the isolation test tube, and the push rod is located inside the isolation test tube. The push rod can be extended and retracted along the height direction of the isolation test tube under the drive of the drive motor.

[0025] According to the above technical means, the drive motor is the power source of the electric push rod. The drive motor is connected to the push rod through a mechanical transmission device, which converts the rotational motion of the drive motor into the linear motion of the push rod.

[0026] Beneficial effects achieved by this utility model:

[0027] This utility model achieves automated or semi-automated sampling through the integration of a telescopic assembly and a delivery tube. Operators simply operate the telescopic assembly to control the delivery tube's vertical movement within the separation tube, easily obtaining rubber asphalt samples at varying heights. This mechanized operation reduces human interference. Furthermore, operators avoid direct contact with the hot rubber asphalt, thereby minimizing safety risks and protecting their safety.

[0040] It should be noted that, unless there is a conflict, the embodiments and technical features in the embodiments of this application can be combined with each other, and the detailed descriptions in the specific embodiments should be understood as explanations of the purpose of this application and should not be regarded as improper limitations on this application.

[0041] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0043] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0045] The technical solution of this embodiment is described in detail below with reference to the specific drawings.

[0046] like Figure 1 and Figure 2 As shown, this embodiment proposes a rubber asphalt separation sampling device, including: an isolation test tube 1, a feed pipe 2 and a telescopic component 3, the telescopic component 3 is installed on the isolation test tube 1, and at least part of the telescopic component 3 is located in the isolation test tube 1, and the part of the telescopic component 3 located in the isolation test tube 1 can be telescoped along the height direction of the isolation test tube 1; one end of the feed pipe 2 is located in the isolation test tube 1, for absorbing the rubber asphalt in the isolation test tube 1, and one end of the feed pipe 2 is connected to the part of the telescopic component 3 located in the isolation test tube 1, so that one end of the feed pipe 2 can absorb rubber asphalt at different heights along the height direction of the isolation test tube 1; a sample cup 4, the sample cup 4 is located at the other end of the feed pipe 2, and the sample cup 4 is used to receive the rubber asphalt absorbed by the feed pipe 2.

[0047] During specific use, place the rubber asphalt sample in the isolation test tube 1 and heat it to an appropriate temperature as needed to ensure that the asphalt is in a fluid state for easy sampling. Install the telescopic component 3 on the isolation test tube 1 and ensure that its telescopic part is located inside the isolation test tube 1. Connect one end of the feed pipe 2 to the telescopic component 3 located in the isolation test tube 1, and connect the other end to the sample cup 4 to ensure that the connection is tight and leak-free. Adjust the position of the telescopic component 3 according to the height at which sampling is required. By controlling the telescopic function of the telescopic component 3, one end of the feed pipe 2 is moved to the required sampling height. The feed pipe 2 draws the rubber asphalt sample, and stops the drawing operation when the sampling volume reaches the requirement.

[0048] This embodiment achieves automated or semi-automated sampling through the integration of the telescopic assembly 3 and the delivery tube 2. The operator simply manipulates the telescopic assembly 3 to control the delivery tube's vertical movement within the separation tube 1, allowing easy acquisition of rubber asphalt samples at varying heights. This mechanized operation reduces human interference. Furthermore, the operator avoids direct contact with the hot rubber asphalt, thereby minimizing safety risks and protecting the operator.

[0049] The feed pipe 2 should be made of a material with good corrosion resistance and high temperature resistance. In this embodiment, the feed pipe 2 is preferably made of a rubber material (such as an oil-resistant and solvent-resistant rubber material such as acrylonitrile-butadiene rubber (NBR) or chloroprene rubber (CR). The rubber tube is not easily corroded by asphalt due to its good flexibility and corrosion resistance, and the rubber tube can withstand certain pressure and temperature changes, which is convenient for conveying the rubber asphalt medium. In this embodiment, in order to increase the strength and wear resistance of the rubber tube, a rubber tube with a reinforcement layer, such as a steel wire reinforced rubber tube, can be selected. This type of pipeline has a steel wire or fiber reinforcement layer embedded in the rubber layer to improve its pressure bearing capacity and service life.

[0050] In this embodiment, Figure 1 As shown, a feed port 11 is formed on the separation test tube 1 , and the feed port 11 is located at the top of the separation test tube 1 , and the feed port 11 is connected to the inside of the separation test tube 1 so as to input rubber asphalt into the separation test tube 1 .

[0051] like Figure 1 As shown, a water inlet 12 and a drain outlet 13 are formed on the side wall of the isolation tube 1. The water inlet 12 and the drain outlet 13 are respectively connected to the interior of the isolation tube 1, with the water inlet 12 near the top of the isolation tube 1 and the drain outlet 13 near the bottom of the isolation tube 1. After the test is completed, if there is rubber asphalt residue on the inner wall of the isolation tube 1, water is supplied through the water inlet 12 to clean the interior of the isolation tube 1, and the cleaned water is discharged from the drain outlet 13.

[0052] like Figure 1 As shown, a rubber asphalt separation sampling device further includes a support 5 , a sample cup 4 is mounted on the support 5 , and the other end of the feed pipe 2 is mounted on the support 5 and located above the sample cup 4 .

[0053] The support 5 provides a stable support platform for the sample cup 4 and the feed pipe 2, preventing the sample from splashing or being contaminated due to shaking or instability of the equipment during the sampling process, and helps to keep the sampling environment clean and tidy and the sample pure.

[0054] like Figure 1As shown, a rubber asphalt separation sampling device also includes a turntable 6, which is rotatably mounted on a support 5 and is located below the other end of the feed pipe 2; there are multiple sample cups 4, each of which is mounted on the turntable 6, and the multiple sample cups 4 are evenly distributed along the rotation direction of the turntable 6. The rotation of the turntable 6 can drive each sample cup 4 to move to directly below the sample cup 4.

[0055] The introduction of the turntable 6 enables automated movement of the sample cups 4. Operators simply rotate the turntable 6 to sequentially move different sample cups 4 directly under the feed pipe 2, eliminating the need to manually replace or move the sample cups 4. This significantly improves sampling efficiency. The design of the turntable 6 ensures that each sample cup 4 is accurately positioned directly under the feed pipe 2, avoiding sampling errors caused by positional deviations. The uniform distribution of multiple sample cups 4 along the turntable's rotational direction facilitates uniform sampling of rubber asphalt samples at different heights or locations, improving the representativeness and accuracy of the sampling.

[0056] In this embodiment, the support 5 is formed with a retaining groove 52, which is shaped to match the turntable 6. The turntable 6 can be inserted into the retaining groove 52 for rotation. The retaining groove 52 provides a precise rotational track for the turntable 6, ensuring that the turntable 6 does not deviate from the predetermined position during rotation, thereby improving the stability and accuracy of rotation. Once the turntable 6 is inserted into the retaining groove 52, the retaining groove 52 provides additional support for the turntable 6, making it more stable when bearing the weight of the sample cup and the rubber asphalt, and less prone to deformation or damage. The shaking and vibration during rotation are greatly reduced.

[0057] like Figure 1 As shown, a rubber asphalt separation sampling device also includes a plurality of cup sleeves 7 , each cup sleeve 7 is fixed on a turntable 6 , and the plurality of cup sleeves 7 are evenly distributed along the rotation direction of the turntable 6 ; each sample cup 4 is installed on each cup sleeve 7 .

[0058] The cup sleeve 7 provides additional support for the sample cup 4, preventing it from shaking or tilting during the rotation of the turntable 6 or during sampling, thereby ensuring accurate and safe sampling. When the turntable 6 rotates, the cup sleeve 7 can absorb some of the impact force, reducing the direct impact on the sample cup 4 and the sample inside, and preventing sample splashing or contamination.

[0059] In this embodiment, the cup sleeve 7 and the turntable 6 are integrally formed, eliminating the need for additional connectors or fasteners between the cup sleeve 7 and the turntable 6. This reduces the risk of structural failure due to loose or damaged connectors and enhances the structural strength of the entire sampling device. Because the cup sleeve 7 is tightly coupled to the turntable 6, the turntable 6 can drive the cup sleeve 7 and the sample cup on it to move stably during rotation, reducing shaking and vibration and improving sampling stability.

[0060] like Figure 1As shown, a rubber asphalt separation sampling device further includes a turntable drive assembly 8, which is connected to the turntable 6 and can drive the turntable 6 to rotate.

[0061] The turntable drive assembly 8 realizes the automatic rotation of the turntable 6, eliminating the need for manual operation, greatly improving the automation level of the sampling process. Through the precise control of the turntable drive assembly 8, different sample cups can be quickly moved to the sampling position, reducing waiting time and improving sampling efficiency.

[0062] like Figure 1 As shown, the turntable drive assembly 8 includes a handwheel 81 and a drive gear 82. The handwheel 81 is coaxially connected to the drive gear 82, and the handwheel 81 can drive the drive gear 82 to rotate; a rack 61 is formed on the outer edge of the turntable 6, and the rack 61 is engaged with the drive gear 82, so that the turntable drive assembly 8 can drive the turntable 6 to rotate.

[0063] The handwheel 81 and the drive gear 82 are coaxially connected together by some means (such as key connection, spline connection or tight fit, etc.) to ensure that they can rotate synchronously. When the operator turns the handwheel 81, its rotational motion is transmitted to the drive gear 82 through the coaxial connection, causing the drive gear to also start to rotate. The outer edge of the turntable 6 is designed with a rack 61. The rack 61 is a linear gear whose teeth can mesh with the teeth of the drive gear 82. When the drive gear 82 rotates driven by the handwheel 81, its teeth mesh with the rack 61 on the turntable 6, thereby converting the rotational motion of the drive gear 82 into the linear (or circular) motion of the turntable 6. Since the rack 61 is fixed to the turntable 6, the rotation direction of the turntable 6 is consistent with the rotation direction of the drive gear 82.

[0064] like Figure 1 As shown, a rotating shaft 62 is formed on one side of the turntable 6 close to the support 5 , and the rotating shaft 62 is located at the rotation center of the turntable 6 ; a groove 51 is formed on the support 5 , and the rotating shaft 62 is installed in the groove 51 .

[0065] The rotating shaft 62 is located at the rotation center of the turntable 6, ensuring that the turntable can rotate smoothly and evenly. The shape and size of the groove 51 should match the rotating shaft 62 to ensure that the rotating shaft 62 can be tightly and stably installed in the groove 51, thereby reducing friction and shaking during rotation and improving the accuracy and stability of rotation.

[0066] like Figure 1 As shown, the depth of the groove 51 is the same as the length of the rotating shaft 62 .

[0067] Because the depth of the groove 51 perfectly matches the length of the shaft 62, the shaft 62 can be completely embedded in the groove 51, forming a tight fit, reducing shaking and vibration caused by excessive clearance, thereby enhancing the stability of the turntable 6 during rotation. The tight fit also means that the position of the shaft 62 in the groove 51 is more fixed, reducing uneven rotation caused by deviation or tilt.

[0068] like Figure 1 As shown, a rubber asphalt separation sampling device further includes a suction pump 9 , which is installed on the feed pipe 2 .

[0069] The suction pump 9 can generate negative or positive pressure to automatically draw the rubber asphalt from the separation tube 1, reducing manual intervention and improving the efficiency and safety of the sampling process. The drawn rubber asphalt is transported through the delivery pipe 2 to the sample cup 4 on the turntable 6.

[0070] In this embodiment, a variety of suction pumps are available, including centrifugal pumps, plunger pumps, and diaphragm pumps. Each pump has its own specific operating principle and application scenarios. When selecting a pump, consider the viscosity, temperature, and corrosiveness of the rubber asphalt, as well as the specific requirements of the sampling device. For example, for rubber asphalt with higher viscosity, a pump with stronger suction and greater flow rate may be required; for applications requiring precise flow control, a pump with adjustable flow rate may be appropriate.

[0071] In this embodiment, the suction pump 9 is preferably installed on the delivery pipe 2, located between the separation tube 1 and the sample cup 4, to ensure that during the sampling process, the rubber asphalt can be smoothly sucked from the separation tube 1 and delivered to the sample cup 4. During installation, attention should be paid to the sealing between the suction pump 9 and the delivery pipe 2 to prevent the rubber asphalt from leaking or air from entering the pipe.

[0072] As you can imagine, the suction pump 9 is typically connected to a control system for automated control. This control system can start, stop, or adjust the suction pump's operating status based on pre-set programs or operator instructions. Furthermore, monitoring devices such as flow sensors and pressure sensors may be included to monitor the suction pump's operating status and the delivery of the rubber asphalt in real time, thereby ensuring the accuracy and reliability of the sampling process.

[0073] like Figure 2 As shown, the telescopic component 3 is an electric push rod, which includes a push rod 31 and a drive motor 32. The push rod 31 is driven and connected to the drive motor 32. The drive motor 32 is installed at the top of the separation tube 1, and the push rod 31 is located inside the separation tube 1. The push rod 31 can be extended and retracted along the height direction of the separation tube 1 under the drive of the drive motor 32.

[0074] The drive motor 32 is the power source of the electric push rod. The drive motor 32 is connected to the push rod 31 through a mechanical transmission device, and the rotational motion of the drive motor 32 is converted into the linear motion of the push rod 31.

[0075] It is easy to imagine that the material of the push rod 31 is usually selected from a metal or alloy with high strength, corrosion resistance and wear resistance to ensure its stability and durability during use. In terms of design, the push rod 31 may adopt a precise guide mechanism to ensure its straightness and accuracy during the extension and retraction process.

[0076] The drive motor 32 is usually connected to a control system to achieve remote or automatic control. The control system can start, stop or adjust the speed and direction of the motor according to a preset program or operator's instructions, thereby controlling the telescopic speed and position of the push rod 31.

[0077] When sampling is required, the control system sends a command to the drive motor 32, causing it to begin rotating. Through a mechanical transmission mechanism, the rotational motion of the drive motor 32 is converted into linear motion by the push rod 31. Driven by the drive motor, the push rod 31 telescopes along the height of the separation tube 1, thereby enabling the sampling of the rubber asphalt sample.

[0078] The serial numbers of the embodiments of this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are only preferred embodiments of this application and do not limit the scope of the patent of this application. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the scope of patent protection of this application.
