[0021] 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.
[0022] The utility model provides Figure 1-5 The asphalt pavement data measuring device shown in the figure comprises a measuring host 1 and a host panel 3 arranged at the top of the measuring host 1. The measuring host 1 and the host panel 3 are fixedly connected by buckles and embedded screws. A measuring base 9 is arranged at the bottom of the measuring host 1. A handle fixing frame 8 is arranged on the outer wall of the rear end of the measuring host 1. An operating handle 7 is arranged at the front end of the top of the handle fixing frame 8. The operating handle 7 is located at the upper rear side of the host panel 3. A data touch screen 5 is arranged inside the middle section of the host panel 3. An interface panel 4 and a start-stop button 6 are arranged on the front side of the data touch screen 5. The start-stop button 6 is located on the right side of the interface panel 4. When using the asphalt pavement data measuring device, First, you need to hold the operating handle 7 and lift the entire asphalt pavement data measuring device, then you need to determine the measurement position of the asphalt pavement, and lower the asphalt pavement data measuring device so that the measuring base 9 is directly placed on the asphalt pavement, then you need to set the measurement mode of the measuring host 1 through the data touch screen 5, and then press the start-stop button 6 to start the measuring host 1, so that the asphalt density measuring probe 11, relative moisture measuring probe 10 and pavement thickness measuring probe 12 inside the measuring base 9 measure the asphalt pavement, and the measured data will be displayed through the data touch screen 5, so that the user can record the measurement data conveniently.
[0023] like Figure 1 , Figure 2 and Figure 3As shown, an asphalt density measuring probe 11 is arranged inside the center of the measuring base 9, a relative moisture measuring probe 10 is arranged on the front side of the asphalt density measuring probe 11, and a pavement thickness measuring probe 12 is arranged on the rear side of the asphalt density measuring probe 11. The outer shell of the measuring host 1 and the host panel 3 are both made of aluminum alloy, and the outer wall of the measuring host 1 is also sprayed with paint. When the asphalt pavement data measuring device measures the asphalt pavement through the asphalt density measuring probe 11, the relative moisture measuring probe 10 and the pavement thickness measuring probe 12, the asphalt density measuring probe 11 will use the absorption characteristics of radioactive rays or nuclear radiation to measure the asphalt density. When the rays pass through the asphalt pavement, the degree to which they are absorbed by asphalts of different densities will be different. By measuring the intensity change of the rays passing through the asphalt pavement, the probe can calculate the density of the asphalt. This method can not only quickly and accurately measure the asphalt density, but also does not require direct contact with the measured object, and has high safety and convenience, and is relatively The moisture measuring probe 10 usually uses the principles of capacitance, resistance or microwaves to measure the moisture content in asphalt. When moisture exists in asphalt, it will change the electrical conductivity or dielectric constant of asphalt, thereby affecting the measurement result of the probe. By measuring the changes in electrical properties caused by moisture in the asphalt pavement, the probe can quickly and accurately calculate the moisture content of the asphalt. This method is very suitable for engineering occasions that require real-time monitoring of the moisture content of the asphalt pavement. It has the advantages of fast response speed and simple operation. The pavement thickness measuring probe 12 usually uses the propagation characteristics of sound waves or microwaves to measure the thickness of the asphalt pavement. When the sound waves or microwaves pass through the asphalt pavement, their propagation speed will be affected by the thickness of the pavement. By measuring the time or frequency changes of the sound waves or microwaves propagating in the pavement, the probe can quickly and accurately calculate the thickness of the asphalt pavement. This method does not require direct contact with the object to be measured, has the advantages of non-contact measurement and fast response speed, and is suitable for various pavement thickness measurement occasions.
[0024] like Figure 1 , Figure 4 and Figure 5As shown, the left and right ends and the front end of the measuring host 1 are connected to the anti-friction protection device 2, and the anti-friction protection device 2 includes a U-shaped lifting sleeve 13, a hand-tightened screw 15, a metal lifting strip 16 and an anti-slip lifting groove 17. The U-shaped lifting sleeve 13 is sleeved on the left and right ends and the front end of the measuring host 1. The top of the front center of the U-shaped lifting sleeve 13 and the tops of the left and right ends of the rear end are both provided with metal lifting strips 16. The metal lifting strips 16 are provided inside the anti-slip lifting groove 17. A hand-tightening screw 15 is inserted, and the screw rod of the hand-tightening screw 15 is threadedly inserted into the outer wall of the measuring host 1. The anti-friction protection device 2 includes an anti-friction protection block 14, a ball hole 18 and a metal ball 19. The front end of the U-shaped lifting sleeve 13 and the outer walls at both ends are provided with anti-friction protection blocks 14. The anti-friction protection block 14 is provided with a ball hole 18 inside, and a metal ball 19 is provided in the ball hole 18. The bottom quarter of the metal ball 19 is exposed outside the outer wall of the bottom end of the anti-friction protection block 14.
[0025] like Figure 1 , Figure 4 and Figure 5As shown, the height of the U-shaped lifting sleeve 13 is greater than the thickness of the measuring base 9, and the U-shaped lifting sleeve 13 can move up and down outside the measuring host 1. The outer wall of the metal ball 19 and the inner wall of the ball hole 18 are smooth and burr-free. The metal ball 19 can rotate universally in the ball hole 18. When the asphalt pavement data measuring device needs to be used frequently for data measurement, the measuring base 9 needs to be frequently attached to the asphalt pavement, which will easily cause excessive wear of the measuring base 9, resulting in inaccurate measurement. At this time, the anti-friction protection device 2 needs to be used to prevent The asphalt road surface causes wear on the measuring base 9, so it is necessary to lower the anti-friction protection device 2 so that the anti-friction protection device 2 replaces the measuring base 9 to contact the asphalt road surface. During the specific operation, it is necessary to loosen the three hand screws 15 so that the hand screws 15 unlock the metal lifting strip 16, and then it is necessary to lower the U-shaped lifting sleeve 13 to lower the entire device until the metal ball 19 exposed at the bottom of the anti-friction protection block 14 fits on the asphalt road surface, and then continue to slide down so that the metal ball 19 replaces the measuring base 9 to contact the asphalt road surface. , and it is necessary to control the distance between the measuring base 9 and the asphalt pavement so that the distance between the two is extremely small, and then maintain this state and re-tighten the three hand-tightening screws 15. By tightening the hand-tightening screws 15, the metal lifting strip 16 is firmly clamped against the outer wall of the measuring host 1, so that the lowered anti-friction protection device 2 will be locked in position, and then the asphalt pavement data measuring device can be used normally to measure the asphalt pavement data. After placing the asphalt pavement data measuring device on the asphalt pavement, multiple metal balls 19 will be fully placed on the asphalt pavement. At this time, the measuring base 9 does not contact the asphalt pavement, so it will not cause the asphalt pavement to frequently contact the measuring base 9 and excessively wear the measuring base 9. Because the metal balls 19 can roll in the ball holes 18, it is not necessary to advance and put down the asphalt pavement data measuring device when moving it. It is only necessary to directly push the asphalt pavement data measuring device. The metal balls 19 will make the asphalt pavement data measuring device flexibly move on the asphalt pavement through the rolling effect, making the asphalt pavement data measuring device easier to use.
