Description

Technical Field

[0001] This utility model relates to the field of asphalt testing devices, and in particular to a device for detecting the variability of asphalt mixtures made from inferior materials. Background Technology

[0002] Asphalt testing equipment is an indispensable tool in road construction and maintenance. It is mainly used to evaluate the performance and quality of asphalt materials. These devices can accurately measure multiple indicators of asphalt to ensure that asphalt mixtures meet the technical requirements for road construction. The operation methods and technical parameters of asphalt testing equipment are crucial for obtaining accurate and reliable test results.

[0003] Existing asphalt testing equipment typically tests existing asphalt roads or asphalt samples. However, this approach has the drawback that testing existing asphalt roads can damage them, while testing only samples cannot accurately demonstrate the quality standards of the finished asphalt roads.

[0004] Therefore, existing asphalt testing devices typically test already formed road surfaces, which can damage the asphalt road. Testing only samples cannot reflect the state of asphalt after it has become a road. Therefore, a device for testing the variability of asphalt mixtures of inferior materials can be designed to simulate the testing of asphalt roads. Utility Model Content

[0005] Existing asphalt testing equipment typically tests existing asphalt roads or asphalt samples. However, this approach has the drawback that testing existing asphalt roads can damage them, while testing only samples cannot accurately demonstrate the quality standards of the finished asphalt roads.

[0006] The technical solution of this utility model is as follows: a device for detecting the variability of asphalt mixtures of inferior quality materials, comprising a grooved asphalt testing frame and a simulation component. The simulation component is provided at one end of the grooved asphalt testing frame. The simulation component includes a transverse moving motor. A transverse moving screw is rotatably connected to one end of the transverse moving motor via a coupling. A lifting sliding frame is clearance-fitted to the outer end of the transverse moving screw. A lifting screw is provided inside the lifting sliding frame. A lifting motor is rotatably connected to the upper end of the lifting screw via a coupling. A simulated lifting plate is clearance-fitted to the outer end of the lifting screw. A pressure testing roller is provided on the simulated lifting plate. A rolling motor is rotatably connected to the front end of the pressure testing roller via a coupling. A motor support rod is installed on the upper end of the rolling motor.

[0007] Preferably, a lateral moving screw and a simulated lifting plate are set up to assist in leveling the asphalt road, a pressure testing roller is used to test the pressure of the asphalt road, and a rolling motor is set up to provide power. This solves the problem that existing asphalt testing devices usually test the already formed road surface or test the asphalt sample. However, the disadvantage of this is that testing the formed asphalt road will damage the asphalt road, while testing only the sample cannot accurately show the qualification standard of the formed asphalt road.

[0008] As a preferred embodiment, cylinder support plates are installed at both the front and rear ends of the simulated lifting platform. A leveling cylinder is installed at the upper end of the cylinder support plate, a leveling chain is installed on the leveling cylinder, a leveling plate is installed on the leveling chain, and a leveling hinge is provided on the leveling plate, which serves to level the simulated asphalt road.

[0009] As a preferred option, the grooved asphalt testing frame has an asphalt testing pad inside, and two support legs are installed at the lower end of the grooved asphalt testing frame to prevent asphalt from sticking to the equipment.

[0010] As a preferred option, an asphalt softening point tester is installed at the front end of the grooved asphalt testing frame, and two discharge cylinders are installed on the grooved asphalt testing frame to detect the softening point.

[0011] As a preferred embodiment, a discharge chain is installed on the discharge cylinder, a discharge gate is installed on the discharge chain, and a discharge hinge is installed on the discharge gate, which serves to discharge the tested asphalt.

[0012] Preferably, a support bend is installed on the other end of the asphalt testing frame with a groove, a mixing support frame is installed on the upper end of the support bend, and a mixing motor is installed on the upper end of the mixing support frame, which serves to provide support and power.

[0013] Preferably, the lower end of the stirring motor is rotatably connected to a stirring rod via a coupling. Three stirring blades are installed on the stirring rod, and a mixing funnel is installed on the support frame to perform the stirring function.

[0014] The beneficial effects of this utility model are:

[0015] 1. A lateral moving screw and a simulated lifting plate are used to assist in leveling the asphalt road. Pressure testing rollers are used to test the pressure of the asphalt road. A rolling motor provides power. First, the lateral moving motor is started to make the lateral moving screw start to rotate. The lifting sliding frame on the lateral moving screw moves to one end. The cylinder at the leveling point drives the iron chain at the leveling point to pull the pushing plate to the vertical. The lifting motor is started to rotate the lifting screw, which makes the simulated lifting plate descend to the required ground height. The pushing plate then spreads the asphalt. This solves the problem that existing asphalt testing devices usually test the already formed road surface or test asphalt samples. However, the disadvantage of this is that testing the formed asphalt road can damage the asphalt road, while testing only the sample cannot accurately reflect the qualification standard of the formed asphalt road.

[0026] Please see Figures 1-3In this embodiment, the simulation component includes a lateral movement motor 201. A lateral movement screw 202 is rotatably connected to one end of the lateral movement motor 201 via a coupling. A lifting sliding frame 203 is fitted with the outer end of the lateral movement screw 202 with a clearance fit. A lifting screw 204 is disposed inside the lifting sliding frame 203. A lifting motor 205 is rotatably connected to the upper end of the lifting screw 204 via a coupling. A simulated lifting plate 206 is fitted with the outer end of the lifting screw 204 with a clearance fit. The simulated lifting plate 206 is provided with... The pressure testing roller 207 has a rolling motor 208 rotatably connected to its front end via a coupling. The upper end of the rolling motor 208 is equipped with a motor support rod 209. The simulated lifting plate 206 has cylinder support plates 210 installed at both its front and rear ends. The upper end of the cylinder support plate 210 is equipped with a flattening cylinder 211. The flattening chain 212 is installed on the flattening cylinder 211. The flattening plate 213 is installed on the flattening chain 212. The flattening hinge 214 is provided on the flattening plate 213.

[0027] During testing, asphalt is poured into asphalt testing pad paper 3. Depending on the testing conditions, the mixture is poured into mixing funnel 15. The mixing motor 12 is started to drive the three mixing blades 14 to fully mix the mixture. After the mixture and asphalt are mixed, a portion of the asphalt is placed into the asphalt softening point tester 5 for softening point testing. The lateral movement motor 201 is started to rotate the lateral movement screw 202, causing the lifting sliding frame 203 to move towards the support bend frame 10. The flattening cylinder 211 drives the flattening chain 212 to pull the flattening plate 213 to vertical. The lifting motor 205 is started to rotate the lifting... Screw 204 lowers the simulated lifting plate 206 to the required ground height. Asphalt is spread evenly by the push plate 213. After drying for a period of time, the rolling motor 208 is started to rotate the pressure test roller 207. The lateral movement motor 201 and the lateral movement screw 202 cause the pressure test roller 207 to perform pressure tests on the formed simulated asphalt road. After all tests are completed, the discharge gate 8 on the discharge chain 7 is tilted and opened by the cylinders 6 at the two discharge points. The asphalt test pad 3 is discharged along with the asphalt. A new asphalt test pad 3 is then replaced for a new test.

This solves the problem that existing asphalt testing devices usually test the already formed road surface or test asphalt samples. However, the disadvantage of this is that testing the formed asphalt road will damage the asphalt road, while testing only the sample will not accurately show the qualification standard of the formed asphalt road.
