Description

Technical Field

[0001] This utility model relates to the field of waterborne epoxy asphalt production and processing technology, and in particular to a waterborne epoxy asphalt performance testing device. Background Technology

[0002] Waterborne epoxy asphalt is a mixture of epoxy resin, base asphalt, and various additives through complex chemical modification. It is mainly used in large-scale highway construction projects such as concrete bridge decks and viaducts. It has excellent ductility and shrinkage resistance, resulting in high adhesion to steel plates and good performance. Furthermore, epoxy asphalt has high strength, three to four times that of ordinary asphalt. During the processing and production of waterborne epoxy asphalt, adhesion testing is an essential step to ensure performance and product quality. Adhesion testing assesses the degree of bonding between the asphalt and aggregate, thereby determining the stability and durability of the asphalt mixture.

[0003] Currently, in actual testing, asphalt blocks need to be compressed until they break, and the adhesion of the asphalt is evaluated by the time and degree of breaking. However, after the asphalt blocks are broken, the fragments are numerous and scattered, making collection difficult. Furthermore, during the testing process, there is a risk of fragments splashing from the gaps, resulting in low operational safety. Utility Model Content

[0004] The purpose of this application is to provide a water-based epoxy asphalt performance testing device to solve the problems of difficulty in collecting fragments after asphalt blocks are broken due to their large quantity and dispersion, and low operational safety due to fragments easily splashing from gaps during the testing process.

[0005] To solve the above-mentioned technical problems, this application provides a water-based epoxy asphalt performance testing device, comprising:

[0006] A testing platform is fixed by support legs. The testing platform is provided with a feeding trough, which is open at the bottom. A hydraulic cylinder is fixed to one side of the testing platform by a support plate. A pressure sensor is fixed to the lower end of the hydraulic cylinder. A pressure column corresponding to the feeding trough is fixed to the lower end of the pressure sensor. A cover is provided at the upper end of the pressure column. Bearing plates are slidably installed on opposite sides of the testing platform by mounting components. The adjacent ends of the two bearing plates are located in the feeding trough and abut against each other. A collection box corresponding to the feeding trough is provided below the testing platform.

[0007] In a preferred embodiment, a water-based epoxy asphalt performance testing device includes an installation assembly comprising two horizontal plates fixed to the testing platform. One end of each of the two horizontal plates is fixed to an installation plate, and a threaded rod is screwed onto the installation plate. One end of the threaded rod is rotatably connected to one end of the bearing plate.

[0008] The solution requires detailed explanation of a water-based epoxy asphalt performance testing device, wherein the outer end of the threaded rod is also fixed with a screw handle.

[0009] The solution requires further detailed explanation of a water-based epoxy asphalt performance testing device, wherein the horizontal plate and the mounting plate are integrally molded.

[0010] As a preferred embodiment, a water-based epoxy asphalt performance testing device includes a cover body comprising an outer extension plate fixed to the upper edge of the pressure column and a cover plate fixed to the lower side of the outer extension plate.

[0011] Correspondingly, the detection platform is provided with a groove corresponding to the cover plate, and the lower side of the cover plate is located in the groove.

[0012] The solution requires detailed explanation of a water-based epoxy asphalt performance testing device, wherein both the outer extension plate and the cover plate are transparent.

[0013] In a preferred embodiment, a water-based epoxy asphalt performance testing device is provided, wherein the bottom of the collection box is also provided with rollers.

[0014] The solution requires detailed explanation of a water-based epoxy asphalt performance testing device, wherein an operating handle is also provided on one side of the collection box.

[0015] Compared with the prior art, the water-based epoxy asphalt performance testing device provided by this utility model includes a testing platform supported and fixed by support legs. A discharge trough is provided on the testing platform, with its bottom open. A hydraulic cylinder is fixed to one side of the testing platform via a support plate. A pressure sensor is fixed to the lower end of the hydraulic cylinder, and a pressure column corresponding to the discharge trough is fixed to the lower end of the pressure sensor. A cover is provided at the upper end of the pressure column. Bearing plates are slidably installed on opposite sides of the testing platform via mounting components. The adjacent ends of the two bearing plates are located within the discharge trough and abut against each other. In use, the asphalt block to be tested can be placed in the discharge trough, supported by the bearing plates. Then, the hydraulic cylinder is extended to move the pressure column downwards, squeezing the asphalt block in the discharge trough until it breaks. The pressure sensor records the pressure data and the breaking time, allowing for the evaluation of the asphalt adhesion performance. During this process, the cover can block the debris splashing out from the gap formed by the pressure column and the discharge trough, improving operational safety. Below the testing platform is a collection box corresponding to the discharge chute. The asphalt fragments produced after crushing are located in the discharge chute. At this time, the installation components are operated to move the two bearing plates in opposite directions to separate them. During this process, the asphalt fragments can fall into the collection box for collection, which can reduce the difficulty of fragment collection. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0021] The core of this application is to provide a water-based epoxy asphalt performance testing device, which solves the problems of difficulty in collecting fragments after asphalt blocks are broken due to their large quantity and dispersion, and low operational safety due to fragments easily splashing from gaps during the testing process.

Figure 2 This is a schematic diagram of a testing platform and support plate installation structure provided in an embodiment of this application. See also... Figures 1 to 2 As shown.

[0023] Example 1

[0024] A performance testing device for water-based epoxy asphalt includes a testing platform 2. Multiple support legs 1 are fixed to the bottom of the testing platform 2, providing support and fixation. The shape and size of the testing platform 2 can be determined according to actual conditions. A material discharge chute 3 is provided on the testing platform 2, with its bottom extending through the testing platform 2. A support plate 4 is fixed to one side of the testing platform 2, and a hydraulic cylinder 40 is fixed to the upper side of the support plate 4. The structure and working principle of the hydraulic cylinder 40 can be determined according to actual conditions. The support plate 4 is essentially an L-plate. A pressure sensor 5 is fixed to the lower end of the hydraulic cylinder 40, recording the pressure applied to the asphalt blocks during the testing process. In actual testing, tools or manual intervention are also required to control the crushing time of the asphalt blocks. Recording is performed, and finally, the adhesion performance of asphalt is evaluated by pressure data and time data. The lower end of the pressure sensor 5 is fixed with a pressure column 6 corresponding to the discharge chute 3, and the upper end of the pressure column 6 is provided with a cover 7. On both sides of the detection platform 2, at opposite positions, a bearing plate 8 is slidably installed by an installation component. Specifically, mounting holes 20 can be provided on both sides of the detection platform 2, and the bearing plate 8 is slidably installed in the mounting holes 20. After installation, the adjacent ends of the two bearing plates 8 are located in the discharge chute 3 and abut against each other. A collection box 9 corresponding to the discharge chute 3 is provided below the detection platform 2.

[0025] During testing, asphalt blocks can be placed in the discharge trough 3. After placement, the asphalt blocks are located on the support plate 8. By extending the hydraulic cylinder 40, the pressure column 6 can be moved down into the discharge trough 3 to squeeze the asphalt blocks until they are broken. During this process, the cover 7 can block the splashed fragments to prevent them from hitting the operator, thus improving operational safety. After testing, the installation assembly can be operated to slide the two support plates 8 in opposite directions to separate them, allowing the fragments in the discharge trough 3 to fall into the collection box 9 for collection, improving the convenience of fragment collection. During this process, as the support plate 8 is pulled away, the fragments on it can fall off the support plate 8 due to the obstruction of the discharge trough 3. The mounting hole 20 should be set so that the support plate 8 can move without allowing fragments to enter through the gap between the support plate 8 and the mounting hole 20.

[0026] Example 2

[0027] Based on Example 1, a water-based epoxy asphalt performance testing device is provided. In order to achieve the sliding installation of the bearing plate 8, the installation assembly preferably includes two horizontal plates 10 fixed to the testing platform 2. One end of the two horizontal plates 10 is fixed to a mounting plate 11. A threaded rod 12 is screwed onto the mounting plate 11. One end of the threaded rod 12 is rotatably connected to one end of the bearing plate 8. In use, the bearing plate 8 can be moved by screwing the threaded rod 12, so that the two bearing plates 8 can be brought closer to each other or separated from each other.

[0028] Based on Example 2, a water-based epoxy asphalt performance testing device is provided. In order to facilitate the screwing operation of the threaded rod 12, preferably, a screwing handle 13 is also fixed at the outer end of the threaded rod 12. In use, the threaded rod 12 can be screwed by operating the screwing handle 13.

[0029] Based on Example 2, for the purpose of improving design convenience, a water-based epoxy asphalt performance testing device can preferably be designed as an integrated molding structure, with the horizontal plate 10 and the mounting plate 11 as an integral molding structure.

[0030] Based on Example 1, in order to improve the blocking effect on splashed debris, the cover 7 preferably includes an extension plate 14 fixed to the upper edge of the pressure column 6 and a cover plate 15 fixed to the lower side of the extension plate 14. Correspondingly, the testing platform 2 is provided with a groove 16 corresponding to the cover plate 15. During the downward movement of the hydraulic cylinder 40, the lower side of the cover plate 15 is located in the groove 16, and the splashed debris can be located in the space formed by the extension plate 14 and the cover plate 15.

[0031] In this embodiment, a water-based epoxy asphalt performance testing device can make both the outer plate 14 and the cover plate 15 transparent to facilitate observation of splashing.

[0032] Based on Example 1, a water-based epoxy asphalt performance testing device is provided, preferably with rollers 17 at the bottom of the collection box 9 to facilitate the movement of the collection box 9.

[0033] In this embodiment, to further improve the ease of moving the collection box 9, a water-based epoxy asphalt performance testing device is preferably provided with an operating handle 18 on one side of the collection box 9. During use, the collection box 9 can be moved by means of the operating handle 18.

[0034] This utility model provides a water-based epoxy asphalt performance testing device, including a testing platform 2 supported and fixed by a support leg 1. A material discharge trough 3 is provided on the testing platform 2, with its bottom open. A hydraulic cylinder 40 is fixed to one side of the testing platform 2 via a support plate 4. A pressure sensor 5 is fixed to the lower end of the hydraulic cylinder 40, and a pressure applying column 6 corresponding to the material discharge trough 3 is fixed to the lower end of the pressure sensor 5. A cover 7 is provided at the upper end of the pressure applying column 6. Bearing plates 8 are slidably mounted on opposite sides of the testing platform 2 via mounting components. The adjacent ends of the two asphalt blocks are located within the discharge trough 3 and abut against each other. During use, the asphalt block to be tested is placed in the discharge trough 3, supported by the bearing plate 8. Then, the hydraulic cylinder 40 extends, causing the pressure column 6 to move downwards, squeezing the asphalt block in the discharge trough 3 until it breaks. Pressure data and the breaking time are recorded by the pressure sensor 5, allowing for the evaluation of the asphalt adhesion performance. During this process, the cover 7 can block the debris splashing out from the gap formed by the pressure column 6 and the discharge trough 3, improving operational safety. Below the testing platform 2 is a collection box 9 corresponding to the discharge trough 3. The asphalt debris generated after crushing is located within the discharge trough 3. At this time, operating the installation assembly causes the two bearing plates 8 to move and separate in opposite directions. During this process, the asphalt debris can fall into the collection box 9 for collection, reducing the difficulty of debris collection.
