Technical Field
[0001] The utility model belongs to the technical field of asphalt detection, and relates to an asphalt penetration detection device. Background Technique
[0002] Asphalt penetration is one of the main quality indicators of asphalt, which is used to measure the hardness, consistency of asphalt, and the ability to resist shear failure, and is an index to characterize the conditional viscosity of viscous asphalt. The asphalt penetration test is to test the depth that a standard needle vertically penetrates into an asphalt specimen from the asphalt surface within 5 seconds under a load of 100 grams at 25°C with the help of an asphalt penetration tester.
[0003] In the actual detection process, the standard needle needs to be in contact with the upper surface of the asphalt placed inside the water bath. Usually, the same sample needs to be detected three times. During the process of lowering the standard needle, it is usually necessary for the staff to observe with the naked eye, and the human influence factor is relatively large, and the detection accuracy is relatively low.
[0004] Therefore, the above problems need to be solved urgently. Content of the Utility Model
[0005] Purpose of the utility model: The purpose of the utility model is to provide an asphalt penetration detection device to solve the above problems.

[0007] A base, on the top of the base is provided a water bath, and a digital dynamic penetrometer (5) is provided on the top of the base;
[0008] A regulating structure is arranged between the bottom of the water bath and the top of the base, and the regulating structure is used to quickly adjust the position of the water bath;
[0009] An auxiliary structure, the auxiliary structure includes a trigger component arranged on the digital dynamic penetrometer and an induction component arranged on the base. The trigger component moves down together with the digital dynamic penetrometer until it triggers the sensor on the induction component, and is used to quickly adjust the position of the standard needle.
[0010] Further, the induction component includes a mounting rod fixedly connected to the surface of the base. An installation ring is slidably connected to the surface of the mounting rod.

[0017] 2.

[0022] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.
[0023] During specific implementation: As Figures 1-4 shown, an asphalt penetration detection device includes:
[0024] A base 1, a water bath 101 is arranged on the top of the base 1, and a digital dynamic penetrometer 5 is arranged on the top of the base 1;
[0025] An adjusting structure 4 is arranged between the bottom of the water bath 101 and the top of the base 1, and the adjusting structure 4 is used to quickly adjust the position of the water bath 101;
[0026] An auxiliary structure, the auxiliary structure includes a triggering component 31 arranged on the digital dynamic penetrometer 5 and an induction component 32 arranged on the base 1. The triggering component 31 moves down together with the digital dynamic penetrometer 5 until it triggers the sensor on the induction component 32, and is used to quickly adjust the position of the standard needle 6.
[0027] A controller 2 is arranged on the surface of the base 1, and an indicator light 201 is arranged on the surface of the controller 2;
[0028] The digital dynamic penetrometer 5 is a relatively mature component in the application of existing technologies. It can move the standard needle 6 down after the standard needle 6 is installed, and realize the penetration detection by automatically releasing the standard needle 6 through starting the digital dynamic penetrometer 5 after touching the asphalt surface;
[0029] As Figure 1 、 Figure 3 and Figure 4 shown, the auxiliary structure includes an induction component 32. The induction component 32 includes a mounting rod 306 fixedly connected to the surface of the base 1. An installation ring 307 is slidably connected to the surface of the mounting rod 306. A pressure sensor 309 is embedded at the top of the installation ring 307. A buffer block 310 is arranged at the top of the pressure sensor 309. An installation shell 308 that is slidably connected to the surface of the mounting rod 306 is arranged at the top of the installation ring 307;
[0030] When the pressure sensor 309 detects that the pressure exceeds the preset value, it can transmit a signal to the controller 2, and the controller 2 transmits the signal to the indicator light 201 and turns on the indicator light 201.
[0031] The upper end of the surface of the mounting shell 308 is fixedly connected to a mounting plate 311. The other end of the mounting plate 311 extends above the water bath 101. The bottom of the mounting plate 311 is fixedly connected to a fixing rod 312. The lower end of the fixing rod 312 is fixedly connected to a contact plate 313. The horizontal height of the top surface of the buffer block 310 is slightly higher than the horizontal height of the bottom surface of the contact plate 313.
[0032] The auxiliary structure further includes a trigger assembly 31. The trigger assembly 31 includes a connecting plate 301 arranged on the surface of the digital dynamic penetrometer. A connecting rod 302 is arranged on the surface of the connecting plate 301. The upper end of the connecting rod 302 penetrates out of the connecting plate 301 and the lower end is rotatably connected to a rotating plate 303. A groove 304 is formed on the surface of the rotating plate 303. A trigger block 305 located above the groove 304 is fixedly connected to the top of the rotating plate 303. When the rotating plate 303 is reset, the groove 304 on it is located directly above the mounting shell 308. Rotating the rotating plate 303 can make the top of it contact with the lower end of the standard needle.
[0033] During use, after installing the standard needle 6, rotate the rotating plate 303 so that the end away from the connecting rod 302 is located below the standard needle 6, and by adjusting the height of the connecting rod 302, make the upper surface of the rotating plate 303 contact with the lower end of the standard needle 6, and limit the position of the connecting rod 302 through a fastening bolt, and then rotate the rotating plate 303 back to its original position. During this process, since the top surface of the rotating plate 303 contacts the lower end of the standard needle 6, it can represent that when the standard needle 6 contacts the asphalt surface, the top surface of the rotating plate 303 and the upper surface of the asphalt are on the same horizontal plane, and at the same time it also represents that the bottom surface of the trigger block 305 is also on the same horizontal plane as the upper surface of the asphalt;
[0034] After installing and placing the asphalt sample, by moving the mounting shell 308, it can move along the surface of the fixed mounting rod 306. During this process, it can drive the mounting ring 307, the mounting plate 311, the fixing rod 312 and the contact plate 313 to move synchronously, and make the bottom surface of the contact plate 313 contact the upper surface of the asphalt. At this time, the upper surface of the buffer block 310 is slightly higher than the upper surface of the asphalt;
[0035] During the process of driving the standard needle 6 to move downward by the digital dynamic penetrometer 5, the connecting plate 301 can be driven to move downward synchronously, so that the installation shell 308 gradually penetrates through the groove 304 and the trigger block 305 until the trigger block 305 contacts and slightly presses the buffer block 310. Since the upper surface of the buffer block 310 is slightly higher than the upper surface of the asphalt, the buffer block 310 can be pressed and transmit the pressure to the pressure sensor 309. When the pressure sensor 309 detects that the pressure exceeds the preset value, it can transmit a signal to the controller 2, and the controller 2 transmits the signal to the indicator light 201 and turns on the indicator light 201 to prompt the staff that the standard needle 6 has moved in place and the detection can be carried out. The operation is simple, which is convenient for subsequent multiple tests and reduces the errors caused by manual operation.
[0036] As Figure 1 and Figure 2 shown, the adjusting structure 4 includes a turntable 401 rotatably connected to the top of the base 1. The top of the turntable 401 is provided with evenly distributed slots 403. The inner wall of the slot 403 is clamped with a plug 402. The upper end of the plug 402 penetrates out of the slot 403 and is fixedly connected to the surface of the water bath 101. The outer edge of the turntable 401 is provided with three annularly distributed limiting holes 405. A mounting block is fixedly connected to the top of the base 1. A limiting rod 404 is arranged on one side of the mounting block. The other end of the limiting rod 404 penetrates through the mounting block and extends into the adjacent limiting hole 405.
[0037] The position of the water bath 101 can be quickly adjusted through the preset limiting holes 405, and then the position of the asphalt placed inside can be adjusted. The asphalt is placed inside the water bath 101 through a tripod. After the first detection is completed, the standard needle is moved to separate from the asphalt and cleaned. At the same time, the limiting rod 404 is pulled to separate from the limiting hole 405 to release the limit on the turntable 401, and the turntable 401 is rotated to drive the water bath 101 to rotate to adjust the position of the asphalt until it moves to the next limiting hole 405, and then the limiting rod 404 can be inserted for limiting for the second detection. The operation is simple, and the staff does not need to adjust the position of the asphalt. The preset position can better conform to the detection standard and reduces the errors caused by manual operation.
[0038] When the utility model is in use, after installing the standard needle 6, the upper surface of the rotating plate 303 is made to contact the lower end of the standard needle 6, and the position of the connecting rod 302 is limited by the fastening bolt. Then, the asphalt sample is placed inside the water bath basin 101, and the bottom surface of the contact plate 313 is made to contact the upper surface of the asphalt by moving the mounting shell 308, and the position of the mounting shell 308 is limited. During the process of driving the standard needle 6 to move downward by the digital dynamic penetrometer 5, the connecting plate 301 can be driven to move downward synchronously, so that the mounting shell 308 gradually penetrates through the groove 304 and the trigger block 305 until the trigger block 305 contacts and slightly presses the buffer block 310. Since the upper surface of the buffer block 310 is slightly higher than the upper surface of the asphalt, the buffer block 310 can be pressed and transmit the pressure to the pressure sensor 309. When the pressure sensor 309 detects that the pressure exceeds the preset value, it can transmit a signal to the controller 2, and the controller 2 transmits the signal to the indicator light 201 and turns on the indicator light 201 to prompt the staff that the standard needle 6 has moved in place and the detection can be carried out. After the first detection is completed, the position of the asphalt can be quickly adjusted under the action of the adjusting structure 4, reducing the error caused by manual operation.

The patent protection scope of the utility model is subject to the claims. All equivalent structural changes made by using the description and drawings of the utility model should be included in the protection scope of the utility model by the same token.
