[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Combined with Figure 1-3, an asphalt pavement testing machine, comprising a mobile frame 1, an electric cylinder 3 is connected to the top of the front end of the mobile frame 1, a telescopic power end of the electric cylinder 3 extends to the bottom of the mobile frame 1 and is connected to a testing frame 4, both ends of the top of the testing frame 4 are connected with limit sleeve rods 10 that penetrate the mobile frame 1, the mobile frame 1 is provided with a limit through hole 11 that matches the limit sleeve rod 10, a plurality of piston cavities 5 are transversely arranged in the testing frame 4, a piston plate 6 is connected to the bottom of the piston cavity 5, a piston rod 7 is connected to the bottom of the piston plate 6, a lower pressure plate 8 is connected to the bottom of the piston rod 7, a pressure sensor 9 is connected to the top of the piston cavity 5, and a regulating valve pipe 23 communicating with the top of the piston cavity 5 is connected to the rear end of the testing frame 4;

[0019] In the specific implementation: by moving the mobile frame 1 to the place where inspection is required, and then driving the inspection frame 4 to descend through the electric cylinder 3, after the bottom lower pressure plate 8 contacts the ground, pressure is applied to the piston chamber 5 through the piston rod 7 and the piston plate 6, and then the pressure is sensed by the pressure sensor 9. In actual situations, it is necessary to set a value for the pressure sensor 9. If the pressure is less than this value, it is judged that there is a problem in the area, that is, the strength of the area is insufficient or there is air in the bottom hole. This is more efficient, accurate and convenient than manual inspection.

[0020] A paint storage box 2 is connected to the middle of the top of the mobile frame 1, and a suction pump 12 is connected to the top of the mobile frame 1. The suction pump 12 is connected to a suction pipe 13 extending to the bottom of the paint storage box 2 and a discharge pipe 14 extending to the bottom of the front end of the mobile frame 1. The paint can be extracted through the suction pump 12. The discharge pipe 14 extends to the front of the detection frame 4 and is connected to a distribution pipe 15. The bottom of the distribution pipe 15 is connected to a drip pipe 16 arranged to match the piston cavity 5. The drip pipe 16 is arranged corresponding to the piston cavity 5 and the lower pressure plate 8, that is, no matter how many piston cavities 5 are set, a drip pipe 16 must be set on the same straight line. The drip pipe 16 is connected to an electric control valve 17 electrically connected to the pressure sensor 9. The top of the paint storage box 2 is connected to a feeding pipe port 18, and the bottom of the paint storage box 2 is connected to a discharge valve pipe 19.

[0021] In the specific implementation, because the detection frame 4 is set at the rear end, when the pressure sensor 9 senses that the pressure at the corresponding position is insufficient, the extraction pump 12 is started to extract the paint from the paint storage box 2, and at the same time, the electric control valve 17 at the corresponding position is opened, and the position is determined by dripping through the drip tube 16, which is convenient for subsequent unified repair operations, thereby further improving the efficiency of subsequent processes.

[0022] A storage box 20 is connected to one side of the top of the mobile frame 1, and a power supply control cabinet 21 is connected to the top of the rear end of the mobile frame 1. A push handle 22 is connected to the top of the rear end of the power supply control cabinet 21. The power supply control cabinet 21 is convenient for powering and controlling the electrical components in the equipment, that is, a rechargeable battery and a controller are provided in the power supply control cabinet 21. This is a common prior art, so it will not be elaborated on.

[0023] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
