[0022] 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.

[0023] In order to solve the technical problems in the prior art that asphalt thickness detection equipment detects asphalt thickness manually, which is time-consuming and laborious, the ruler is far away and it is not convenient to observe the position, and the asphalt attached to the surface cannot be cleaned after the tapered rod is retracted, please refer to Figure 1-4 , providing the following technical solutions:

[0024] In this embodiment, an asphalt thickness inspection device for asphalt roads includes a drive box 1, fixed brackets 2 are fixedly provided on both sides of the drive box 1, and a support plate 201 is provided on the side of the fixed bracket 2 away from the drive box 1. The fixed bracket 2 supports the entire device. After being laid flat, stepping on the support plate 201 with your feet can further ensure the stability of the device during inspection. A cylinder 3 is fixedly provided on the upper end of the drive box 1, and handrails 5 are fixedly provided on the upper ends of both sides of the cylinder 3. Holding the handrails 5 makes it easy to place the device stably. A worm 6 is provided inside the cylinder 3, and one end of the worm 6 passes through and extends to the outside of the drive box 1. A ring 4 is provided below the drive box 1, and the ring 4 is located on the outer wall of the worm 6. A plug 601 is fixedly provided at the bottom end of the worm 6. The plug 601 can reduce the resistance of the asphalt road surface, thereby preventing the worm 6 from breaking and increasing the service life of the worm 6.

[0025] In this embodiment, the ring 4 is fixedly connected to the drive box 1 through a diagonal brace 401, and the inner wall of the ring 4 is fixedly provided with bristles 402, which are in contact with the outer wall of the worm 6. When the worm 6 is away from the asphalt road surface, the bristles 402 can scrape off the asphalt attached to the surface of the worm 6 to ensure the cleanliness of the worm 6.

[0026] In this embodiment, a rotating shaft 102 is provided inside the driving box 1, and one end of the rotating shaft 102 extends to the outside of the driving box 1 and is connected to the driving motor. A worm gear 101 is fixedly provided on the outer wall of the rotating shaft 102, and the worm gear 101 is connected to the worm 6 for transmission. After the rotating shaft 102 is driven by the external driving motor, it drives the worm gear 101 to rotate, and then transmits to the worm 6 to move the worm 6 downward. The lifting and lowering of the worm 6 is controlled by electric drive, which saves time and effort.

[0027] Slide blocks 602 are fixedly provided on both sides of the worm 6. The slide blocks 602 are slidably connected to the cylinder 3 through the slide grooves 301. The cooperation between the slide blocks 602 and the slide grooves 301 ensures the stability of the worm 6 when it is lifted or lowered.

[0028] A scale 302 is provided on the front end surface of the cylinder 3, and an indicator needle 603 is provided on one side of the cylinder 3. The indicator needle 603 is fixedly connected to the slider 602. The slider 602 can drive the indicator needle 603 to move together during the up and down movement, and cooperate with the scale 302 to facilitate the observation and calculation of the asphalt thickness.

[0029] Working principle: When in use, place the entire device on the asphalt pavement, hold the handrail 5 and step on the support plate 201 to ensure the stability of the equipment during inspection. First, observe and determine the position of the indicator needle 603 pointing to the scale 302, and then connect the rotating shaft 102 to the external drive motor. After the rotating shaft 102 is driven by the external drive motor, it drives the worm wheel 101 to rotate, and then transmits with the worm 6 to make the worm 6 move downward until the plug 601 is inserted into the asphalt to determine the position, and the worm 6 can be controlled to stop moving downward. When the worm 6 is raised and lowered, it drives the slider 602 to slide in the slide groove 301, and then drives the indicator needle 603 to move. The indicator needle 603 finally stops at the position of the scale 302 to determine the depth. By subtracting the previous initial position, the asphalt thickness can be obtained. When the worm 6 is retracted, the bristles 402 on the inner wall of the ring 4 can scrape off the asphalt attached to the surface of the worm 6 to ensure the cleanliness of the worm 6.
