[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, in a liquid state, with a black surface, soluble in carbon disulfide, and is an organic cementing material for waterproofing, moisture-proofing and anti-corrosion. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground, some forming ore layers or accumulating on the earth's crust surface. At present, asphalt is used in road and bridge construction because it has good insulation, heat insulation, moisture-proof, anti-seepage, waterproof, anti-corrosion, rust-proof and other properties. Since asphalt is attached to the roadbed or bridge deck when in use, in order to better achieve the protection effect of asphalt, it is necessary to detect the adhesion of asphalt.

[0003] There are various types of detection devices for the bearing capacity of asphalt pavements on the existing market. However, some detection devices can only be detected at room temperature, which reduces the practicability of the device. When multi-point detection of test blocks is required, it is not convenient to adjust the detection position according to actual needs, and manual adjustment of the position is required, which reduces the detection efficiency. Content of the Utility Model

Detailed implementation manners

[0019] In order to enable those in the technical field to better understand the technical solution in this application, the following will clearly and completely describe the technical solution in the embodiments of this application in conjunction with the drawings.

[0020] The core of this application is to provide a device for detecting the bearing performance of engineering asphalt, which solves the problems in the prior art that some detection devices can only detect at normal temperature, reducing the practicability of the device. When multi-point detection of test blocks is required, it is not convenient to adjust the detection position according to actual needs, and manual adjustment of the position is required, reducing the detection efficiency.

[0022] An asphalt bearing performance detection device for engineering use, including a workbench 1 and a controller 18. The size of the workbench 1 is set according to actual needs. A base 23 is provided at the bottom of the workbench 1 to support and fix the workbench 1. Side plates 2 are symmetrically arranged above the workbench 1. The ends of the side plates 2 away from the workbench 1 are fixedly connected together with a cross plate 3. A detection component is provided below the cross plate 3. The two side plates 2 support the cross plate 3, thereby facilitating the detection component to conduct detection. A transposition groove 12 is provided on one side of each side plate 2 close to the detection component, that is, a transposition groove 12 is provided on one side where the two side plates 2 are close to each other. A transposition block 13 is slidably arranged in the transposition groove 12, and the transposition block 13 can slide in the transposition groove 12. The sides of the transposition blocks 13 close to each other are fixedly connected with a support plate 14. Both ends of the support plate 14 are fixedly connected with the transposition blocks 13 in the transposition groove 12. A detection box 15 is fixed above the support plate 14. During actual use, an asphalt test block is placed in the detection box 15 for detection. Specifically, the size and structure of the detection box 15 can be determined according to actual needs. A rack 11 is fixedly arranged on the lower right side of the support plate 14. A driving motor 9 is fixed above the right side of the workbench 1. The output end of the driving motor 9 penetrates through the right side plate 2 and is connected with a gear 10. The structure and working principle of the driving motor 9 can both refer to the prior art. The gear 10 meshes with the rack 11. The operating principle of the gear 10 and the rack 11 is to convert the rotational motion of the gear 10 into the reciprocating linear motion of the rack 11. When the driving motor 9 is started, the driving motor 9 drives the gear 10 to do circular motion, and the rack 11 engaged with the gear 10 does reciprocating linear motion. Since the rack 11 is fixedly connected to the bottom surface of the support plate 14, the support plate 14 moves reciprocally along with the rack 11, and the asphalt test block in the detection box 15 can move back and forth, thereby realizing multi-point detection and improving the detection efficiency.

[0023] In order to detect the bearing capacity of asphalt at different temperatures, a temperature control component is also provided on the side plate 2. By simulating the weather at different temperatures through the temperature control component, the practicability of the device is improved. The driving motor 9 and the temperature control component are both electrically connected to the controller 18. Preferably, the temperature control component includes a temperature sensor 16 and a heating plate 17. The heating plate 17 and the temperature sensor 16 are respectively fixed on the two side plates 2, and the heating plate 17 and the temperature sensor 16 do not contact each other. The temperature sensor 16 and the heating plate 17 are both electrically connected to the controller 18. The temperature of the environment where the asphalt test block is located is detected by the temperature sensor 16, and the temperature of the test environment is adjusted by the heating plate 17.

[0024] In this embodiment, preferably, the detection component includes a guide rail 4 between the two side plates 2. An electric slider 5 is arranged on the guide rail 4, and the electric slider 5 can move left and right on the guide rail 4. A hydraulic cylinder 6 is connected to the bottom end of the electric slider 5. The piston rod of the hydraulic cylinder 6 faces downward and is fixedly connected to a pressure sensor 7. The structures and working principles of the hydraulic cylinder 6 and the pressure sensor 7 can both refer to the prior art. The bottom of the pressure sensor 7 is connected to a detection head 8. Further, the electric slider 5, the hydraulic cylinder 6, and the pressure sensor 7 are all electrically connected to the controller 18. The position of the electric slider 5 and the hydraulic cylinder 6 are adjusted through the controller 18. It should be noted that the controller 18 can be a PLC module. The PLC module realizes the control of each component through the signal interaction between the components electrically connected to it. The signal interaction of the PLC module is the prior art that is easily thought of by those skilled in the art and is not the focus of this application, so it will not be elaborated here. During actual use, the asphalt test block to be detected is placed on the detection box 15, and the electric slider 5 is run to move it along the guide rail 4, so that the detection head 8 can be brought above the test block. Then the hydraulic cylinder 6 is driven to extend its piston rod, and then the detection head is driven to move downward until it touches the test block. Then the piston rod of the hydraulic cylinder 6 continues to extend, and the test block is pressed by the detection head 8. The applied pressure is detected in real time by the pressure sensor 7 and fed back to the controller 18.

[0025] To facilitate the staff to adjust the height of the detection device according to actual needs, preferably, hydraulic rods 19 are symmetrically arranged between the base 23 and the workbench 1. The hydraulic rods 19 can adjust the height of the workbench 1. To further improve the stability of the detection device during operation and protect the hydraulic rods 19, sliding rods 20 are symmetrically and fixedly connected to the bottom end of the workbench 1. The sliding rods 20 are symmetrically arranged on both sides of the hydraulic rods 19. A fixed rod 22 is sleeved on the outer side of the bottom end of the sliding rod 20. One end of the fixed rod 22 away from the sliding rod 20 is fixedly connected to the base 23. The sliding rod 20 is slidably connected to the fixed rod 22, and the position between the sliding rod 20 and the fixed rod 22 can be adjusted according to the extension and contraction of the hydraulic rod 19. To improve the stability of the device during use, preferably, a threaded rod 21 is arranged on the circumferential side wall of the fixed rod 22. The threaded rod 21 is symmetrically arranged with respect to the central axis of the fixed rod 22. One end of the threaded rod 21 passes through the fixed rod 22 and extends to the inner wall of the sliding rod 20. When detection is required, the hydraulic rod 19 is started, and the hydraulic rod 19 drives the workbench 1 and the sliding rod 20 to move. Then the sliding rod 20 is fixed on the fixed rod 22 through the threaded rod 21, and thus the height of the workbench 1 can be adjusted according to actual needs.

[0026] An asphalt bearing performance detection device provided by the present application has the following working principle: Place the asphalt test block to be detected on the detection box 15, start the hydraulic rod 19, and the hydraulic rod 19 drives the workbench 1 and the sliding rod 20 to move. Then, fix the sliding rod 20 on the fixed rod 22 through the threaded rod 21, and thus the height of the workbench 1 can be adjusted according to actual needs. Run the electric slider 5 to move it along the guide rail 4, and the detection head 8 can be brought above the test block. Then drive the hydraulic cylinder 6 to extend its piston rod, and thus drive the detection head to move downward until it touches the test block. Then continue to extend the piston rod of the hydraulic cylinder 6 to apply pressure to the test block by using the detection head 8. The applied pressure is detected in real time by the pressure sensor 7 and fed back to the controller 18; when multi-point detection of the test block is required, start the drive motor 9, and the drive motor 9 drives the gear 10 to perform circular motion, and the rack 11 engaged with the gear 10 performs reciprocating linear motion. Since the rack 11 is fixedly connected to the bottom surface of the support plate 14, the support plate 14 performs reciprocating linear motion along with the rack 11, and the asphalt test block in the detection box 15 can move back and forth, thereby realizing multi-point detection and improving the detection efficiency. At the same time, the temperature sensor 16 is used to detect the temperature of the environment where the asphalt test block is located, and the heating plate 17 is used to adjust the temperature of the test environment.
