[0001] This utility model relates to the field of asphalt interlayer testing, specifically to a structure for testing the bonding performance of modified emulsified asphalt. Background Technology

[0002] Modified emulsified asphalt, as a cold-construction material, is attracting increasing attention from industry professionals due to its mature production technology and excellent road performance. Modified emulsified asphalt is mainly composed of water, emulsifiers, admixtures, and modified asphalt, possessing good durability and abrasion resistance, thus gaining widespread application. When paving asphalt roads, specialized equipment is typically used to test the bonding properties of the modified emulsified asphalt to obtain bonding performance data and determine whether it meets construction standards.

[0003] Currently, the modified emulsified asphalt bonding performance testing structure can only test asphalt blocks of a specific size. When the size of the block to be tested is outside the specific size range, the testing structure has difficulty testing the bonding performance of the asphalt block, thus its versatility is not high. At the same time, the testing structure for testing large-sized asphalt blocks is bulky, and usually requires a large towing structure to transport the testing structure to the testing location, which is difficult to handle and has low handling efficiency.

[0015] Furthermore, the force measuring component includes a test motor, an output shaft, and a force gauge. The test motor is mounted on the first support member. One end of the output shaft is mounted on the test motor, and the other end is mounted on the second clamp, so that the test motor can drive the output shaft to move the second clamp in the vertical direction. The force gauge is mounted on the output shaft and is used to test the tensile force on the specimen.

[0016] According to the above-mentioned technical means, the test motor drives the output shaft to move the second clamp, which can stretch the specimen. At the same time, the tensile gauge can measure the tensile force on the specimen in real time and accurately, so as to automate the test process and improve the test efficiency.

[0017] Furthermore, the second clamp includes a fixed base, a fixed arm, a movable arm, and a drive motor. The fixed base is mounted on the other end of the output shaft, the fixed arm is fixed on the fixed base, and the movable arm is slidably mounted on the fixed base. The drive motor is mounted on the fixed base and configured to drive the movable arm to move toward or away from the fixed arm, so that the fixed arm and the movable arm can clamp or release the specimen.

[0018] According to the above-mentioned technical means, the drive motor can drive the moving arm to move on the fixed base, realizing the precise clamping of specimens of different sizes by the moving arm and the fixed arm, improving the automation level of specimen clamping, reducing manual intervention, and further improving the accuracy and reliability of testing.

[0019] Furthermore, the movable component includes support legs and casters, the casters being mounted on the support legs; the support legs are mounted on the outer side wall of the protective box and configured to move vertically on the protective box.

[0020] According to the above-mentioned technical means, by adjusting the position of the support legs on the protective box, the casters mounted on the support legs can be adjusted to contact the ground when the protective box needs to be moved and to release contact with the ground when no movement is required, thereby improving the flexibility of the protective box's movement and the stability during testing.

[0021] Furthermore, the support leg has a vertical groove, and the outer wall of the protective box has a slide rail; or, the support leg has a slide rail, and the outer wall of the protective box has a vertical groove. The slide rail and the slide groove cooperate with each other to enable the support leg to move vertically on the protective box.

[0023] Furthermore, a second threaded hole is formed on the support leg, and a second locking bolt is provided in the second threaded hole. The second locking bolt is configured to move within the second threaded hole to abut or release abut against the outer wall of the protective box, thereby locking or releasing the support leg to the outer wall of the protective box.

[0024] According to the above technical means, the support leg is locked to the outer wall of the protective box by the second locking bolt, ensuring that the support leg will not move relative to the protective box when moving, thus improving the stability of the support leg installed on the protective box; at the same time, the structure of the second threaded hole and the second locking bolt cooperating with each other is simple and highly reliable.

[0025] Furthermore, a slag discharge port is formed at the bottom of the protective box, which is used for slag discharge from the protective box.

[0026] According to the above-mentioned technical means, the slag discharge port allows the slag that falls into the protective box due to the destruction of the specimen to be easily discharged, avoiding the accumulation of slag in the box and resulting in inaccurate test results of the specimen.

[0027] Furthermore, a door opening is formed on the protective box, and a door body is provided on the door opening. One side of the door body is hinged to one side of the door opening, and the other side of the door body is engaged with the other side of the door opening, so that the door body can be opened or closed.

[0028] According to the above-mentioned technical means, the doorway facilitates the transport and installation of test specimens into the protective box by the staff. One side of the door is hinged to one side of the doorway, making the door easy to open and close. When the door is closed, it can prevent external equipment or instruments from affecting the test specimens inside the protective box during testing. At the same time, it can also prevent the debris generated during the test specimens from splashing outside the protective box and causing safety hazards, thus ensuring the safety of the testing process.

[0036] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] This embodiment provides, as follows: Figures 1 to 2The modified emulsified asphalt bonding performance testing structure shown includes: a protective box 100 and a sliding frame 200. A sliding cavity 110 is formed in the side wall of the protective box 100, and one end of the sliding frame 200 is slidably installed in the sliding cavity 110 in the vertical direction; a first clamp 300, a second clamp 400, and a force measuring component 500. The first clamp 300 is installed in the protective box 100; the second clamp 400 is installed at one end of the force measuring component 500, and the other end of the force measuring component 500 is installed on the sliding frame 200. The force measuring component 500 is configured to drive the second clamp 400 to move in the vertical direction; the first clamp 300 and the second clamp 400 are used to clamp the two ends of the specimen respectively; and a moving component 600 is installed on the outer side wall of the protective box 100 and is used to drive the protective box 100 to move. The moving component 600 is configured to move in the vertical direction on the protective box 100 to abut against the ground or release from abutment against the ground.

[0039] When testing the bonding performance of modified emulsified asphalt, the moving component 600 is moved vertically downwards until it touches the ground and moves the protective box 100 to the test position. Then, the moving component 600 is moved upwards to release it from the ground, allowing the bottom of the protective box 100 to contact the ground and ensure its stability during testing. The specimen is then placed inside the protective box 100, and the position of the sliding frame 200 within the sliding cavity 110 is adjusted so that both ends of the specimen can be clamped by the first clamp 300 and the second clamp 400, respectively. The sliding frame 200 can also move the second clamp 400 and adjust the distance between it and the first clamp 300 to accommodate specimens of different sizes. After the specimen is installed, the force measuring component 500 can be used to test the specimen.

[0040] After the test is completed, the sliding frame 200 is moved downward to retract, and the moving component 600 is moved downward to make it touch the ground. This allows the protective box 100, as well as the sliding frame 200, the first clamp 300, the second clamp 400, and the force measuring component 500 mounted on the protective box 100, to be easily moved away from the test position.

When it is necessary to test the bonding performance of specimens of different sizes, it is only necessary to move the sliding frame 200 to adjust the distance between the first clamp 300 and the second clamp 400 to clamp specimens of different sizes, which is highly versatile. At the same time, the moving component 600 can drive the protective box 100 to move conveniently, which enhances the flexibility of handling the protective box 100, saves the cost of manual handling, and improves transportation efficiency.

The other end of the force measuring component 500 is installed on the first support member 210. The slidable installation of the second support member 220 in the sliding cavity 110 allows for a certain adjustment space in the position of the first support member 210 connected to the second support member 220, so as to meet different testing requirements and improve the adaptability of the sliding frame 200.

The first locking bolt 111 is configured to move within the first threaded hole to abut or release the abutment against the second support member 220, thereby locking or releasing the second support member 220 within the sliding cavity 110. By locking the second support member 220 within the sliding cavity 110 with the first locking bolt 111, it is ensured that the sliding frame 200 will not move relative to the protective box 100 during testing, thus improving the stability of the sliding frame 200 mounted on the protective box 100. At the same time, the structure of the first threaded hole and the first locking bolt 111 cooperating with each other is simple and highly reliable.

[0044] Preferably, in this embodiment, a handle is provided at the end of the first locking bolt 111 away from the second support member 220.

The second locking bolt 611 is configured to move within the second threaded hole to abut or release from the outer wall of the protective box 100, thereby locking or releasing the support leg 610 to the outer wall of the protective box 100. By locking the support leg 610 to the outer wall of the protective box 100 with the second locking bolt 611, it is ensured that the support leg 610 will not move relative to the protective box 100 during movement, thus improving the stability of the support leg 610 installed on the protective box 100; at the same time, the structure of the second threaded hole and the second locking bolt 611 cooperating with each other is simple and highly reliable.

[0051] like Figure 2 As shown, in this embodiment, a slag discharge port 130 is also formed at the bottom of the protective box 100, which is used for slag discharge from the protective box 100.
