Description

Technical Field

[0001] This utility model belongs to the field of waste asphalt mixture testing technology, and specifically relates to a waste asphalt mixture aging performance testing device. Background Technology

[0002] A waste asphalt mixture aging performance testing device is a device used to evaluate the durability and aging characteristics of waste asphalt mixtures under simulated use conditions. These devices typically include a fixed platform, rollers, and a drive system. By simulating the pressure and friction in a real road environment, the aging effect of waste asphalt mixtures can be observed and evaluated.

[0003] Existing waste asphalt mixture aging performance testing devices fix the waste asphalt mixture on an aging platform, and then drive a moving roller to simulate the effect of rolling the waste asphalt mixture, observing the rolling effect on its surface to achieve the aging test of the waste asphalt mixture. However, during the rolling aging test, the waste asphalt mixture will be worn due to pressure and friction, causing small particles or residues to fall off the aging platform. In order not to affect the subsequent waste asphalt mixture aging performance test, the residues need to be manually cleaned by personnel. Manual cleaning of residues is time-consuming, increasing the time cost of the testing process. After each test, the machine needs to be stopped for cleaning, which affects the efficiency of continuous testing. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a waste asphalt mixture aging performance testing device that can automatically scrape and clean the residue from the workbench into the inside of the collection box. It can quickly complete the cleaning work after each test, reduce downtime, improve testing efficiency, and eliminate the need for frequent shutdowns during continuous testing, thereby improving overall work efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a waste asphalt mixture aging performance testing device, wherein an electric drive unit 1 includes a motor 1 disposed on the rear side of the slide rail, the output shaft of the motor 1 being connected to the rear end of a lead screw 1 via a coupling; a self-cleaning collection mechanism includes a cleaning plate slidably disposed inside the test chamber, the cleaning plate contacting the bottom wall of the test chamber; a connecting frame plate is provided at the lower end of the test chamber, and a lead screw 2 threadedly connected to the cleaning plate is rotatably disposed inside the connecting frame plate; a placement plate is provided on the lower right side of the test chamber, and a collection box is placed inside the placement plate; an electric drive unit 2 for driving the lead screw 2 to rotate is provided on the front side of the connecting frame plate, the electric drive unit 2 including a motor 2 disposed on the front side of the connecting frame plate, the output shaft of the motor 2 being connected to the front side of the lead screw 2 via a coupling.

[0006] As a further improvement of this utility model, a control panel is provided at the lower end of the test box, and motor one, motor two, electric push rod one and electric push rod two are all electrically connected to the control panel.

[0007] As a further improvement of this utility model, the fixing mechanism includes two electric push rods arranged on the left and right sides inside the test box. The two electric push rods are positioned in corresponding left and right positions, and a fixing plate is provided at the lower end of each of the two electric push rods.

[0008] As a further improvement of this utility model, the lower end of the test box is welded with a support frame, and the test box and the support frame are fixed together by welding. The support frame has multiple mounting holes inside.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the chamber door is opened by the handle, and then the waste asphalt mixture is placed on the bottom wall of the test chamber. Then, the electric push rod is activated by the control panel. The telescopic end drives the fixing plates on both sides to move downward to fix the waste asphalt mixture. This method can fix waste asphalt mixtures of different thicknesses.

[0011] Secondly, by controlling the operation of the electric push rod through the control panel, the telescopic end drives the rolling roller on the rotating frame to move downward and contact the waste asphalt mixture to apply a certain test pressure. Then, by controlling the operation of the motor through the control panel, the output shaft drives the lead screw to rotate and drives the rolling roller at the lower end of the electric push rod on the sliding block to move, thereby simulating the rolling of the waste asphalt mixture. By observing the rolling state of the waste asphalt mixture, the aging test can be completed quickly.

[0012] Thirdly, the motor is turned on via the control panel. The output shaft drives the lead screw to rotate, causing the cleaning plate to move backward and push the residue left on the bottom wall of the test chamber out of the test chamber and fall into the collection box, thus cleaning and collecting the residue. It can automatically scrape and clean the residue from the worktable to the inside of the collection box, and can quickly complete the cleaning work after each test, reducing downtime and improving testing efficiency. During continuous testing, there is no need to stop the machine frequently, which improves the overall work efficiency.

[0013] Fourth, the support frame provides stable support for the test chamber, and the height of the support also facilitates aging performance testing by personnel, improving their comfort. Attached Figure Description
