Description

Technical Field

[0002] Patent application number is 201820520494.X A fully automatic asphalt mixture rutting tester, including a workbench, a mounting seat arranged on the workbench, and a sliding seat slidably connected to the mounting seat. The top surface of the workbench is fixed with a test bench for placing an asphalt plate specimen, and the sliding seat is provided with a first driving member, and a pressure wheel assembly for contacting with the asphalt plate specimen is fixed on the first driving member, and the pressure wheel assembly is driven to rise or fall by the first driving member. The first driving member includes a top seat slidably connected to the top of the protective cover, and a first oil cylinder fixed on the top seat. The first oil cylinder can directly drive the pressure wheel assembly to rise or fall, without installing an additional transmission assembly like a motor to convert circumferential rotation into linear motion, which helps to reduce capacity loss and is more efficient.

[0003] However, during the use of the above-mentioned equipment, due to the setting of its internal sliding seat and the first driving member, when installing the test block, it is necessary to manually install the test block in the middle position of the test bench. There is a large error in manually determining the position, which interferes with the test results. Therefore, in response to this situation, we propose a more convenient and practical rutting test machine that meets the usage needs. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the process of road construction, it is necessary to use an asphalt mixture rutting tester. The tester provided by the utility model is specially used for asphalt mixture detection operations in the process of road construction. When using this equipment for detection operations, first of all, it is necessary to check whether the connections between the equipment are tight before use to ensure safety during use. At the same time, at least one staff member is required to operate it during use. During operation, care must be taken to avoid pinching employees.

[0020] like Figure 1-Figure 3 As shown, the utility model provides a technical solution: an improved asphalt mixture rutting tester for road inspection, comprising a shell 1, a clamping mechanism 2 is arranged on the bottom inner wall of the shell 1, the clamping mechanism 2 comprises a linear slide rail 201, the bottom of the linear slide rail 201 is connected to the bottom inner wall of the shell 1, a slider 202 is slidably connected to the top of the linear slide rail 201, a detection mechanism 3 is arranged on the top of the clamping mechanism 2, the detection mechanism 3 comprises a support frame 301, a through hole is penetrated on one side of the support frame 301, and a screw rod 302 is rotatably connected in the through hole.

[0021] It should be noted that during use, when it is necessary to test the sample, first the linear slide rail 201 drives the slider 202 to move, so that the sample can be placed in the clamping mechanism 2, and then the clamping mechanism 2 clamps the sample, and finally the testing mechanism 3 starts to test the sample. The setting of the clamping mechanism 2 makes the sample firmly fixed and not prone to displacement or loosening, thereby ensuring the accuracy and reliability of the test.

[0022] like Figure 2As shown, a test bench 203 is fixedly connected to the top of the slider 202, and clamps 204 are slidably connected to both sides of the top of the test bench 203. Notches are provided on both sides of the top of the test bench 203, and sliding plates 205 are slidably connected in the notches. The sliding plates 205 are connected to the clamps 204. Through holes are provided on both sides of the test bench 203, and first sliding rods 206 are slidably connected in the through holes. One end of the two first sliding rods 206 is connected to the sliding plates 205, and the outer walls of the two first sliding rods 206 are installed with first springs 207. A second sliding rod 208 is fixedly connected to one side of the clamps 204, and a second spring 209 is installed on the outer wall of the second sliding rod 208. A sample 210 is provided on one side of the clamps 204.

[0023] It should be noted that during use, the sample 210 is first placed on the test bench 203, and the linear slide rail 201 drives the slider 202 and the test bench 203 to move. Then, the clamp 204 clamps the sample 210 through the sliding plate 205 under the action of the first slide bar 206 and the first spring 207. At the same time, the second slide bar 208 and the second spring 209 clamp the sample 210 for a second time to ensure that the sample 210 remains in the middle position of the test bench 203, reduce test errors, and can clamp samples 210 of different specifications. It has a wide range of uses, does not require manual calibration, and improves clamping efficiency.

[0024] like Figure 3 As shown, a servo motor 303 is installed at one end of the screw rod 302, a sliding seat 304 is slidably connected to the outer wall of the screw rod 302, a cylinder 305 is installed at the center of the top of the sliding seat 304, and a test wheel 306 is rotatably connected to the output end of the cylinder 305.

[0025] It should be noted that during use, when the sample 210 is placed on the test bench 203 for clamping and fixing, the servo motor 303 first drives the screw 302 to rotate, driving the sliding seat 304 to move. During this process, the cylinder 305 is started to press down to make the test wheel 306 and the sample 210 contact and detect. The combination of the servo motor 303 and the screw 302 can provide precise position adjustment, and the speed and strength during the test process can be adjusted as needed to ensure the readiness of the experiment.

[0026] During use, the sample 210 is first placed on the test bench 203, and then the clamping plate 204 clamps the sample 210 through the sliding plate 205 under the action of the first sliding rod 206 and the first spring 207. At the same time, the servo motor 303 drives the screw rod 302 to rotate, driving the sliding seat 304 to move. In this process, the cylinder 305 is started to press down to make the test wheel 306 and the sample 210 contact and detect, ensuring that the sample 210 remains in the middle position of the test bench 203, reducing test errors, and being able to clamp samples 210 of different specifications. It has a wide range of uses, does not require manual calibration, and improves clamping efficiency.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
