Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of highway engineering detection, in particular to a digitally controlled road surface coring machine based on ground penetrating radar. Background Art
[0002] During highway construction, delivery, completion, and maintenance, construction and inspection agencies often need to drill core samples from the pavement to understand the road's structure, layer thickness, materials, smoothness, strength, and other properties, providing a reference for pavement paving and maintenance. Consequently, pavement coring machines are widely used. Traditional pavement coring machines only have a single coring function, and the core sample selection locations are relatively random and lack specificity. When the core sample does not meet the requirements, multiple sampling is required, which can damage the overall pavement structure. Furthermore, for similar core samples taken at the same location, the consistency of the core samples is poor due to the influence of operator's operating techniques and habits, resulting in inaccurate test results. Summary of the Invention
[0003] In order to solve the above problems, the utility model provides a CNC road coring machine based on ground penetrating radar, which can specifically adopt the following technical solutions:

[0005] The lifting seat is arranged along the mid-vertical line of the horizontal push handle. A fixing seat extending outward is arranged on the top of the vertical guide rod near the horizontal push handle. An electro-hydraulic push rod is arranged on the fixing seat. The piston rod of the electro-hydraulic push rod is connected to the lifting seat.
[0006] The ground penetrating radar is connected to one of the vertical guide rods through a rotating mechanism. The rotating mechanism includes a second rotating motor arranged on the loading plate. The second rotating motor is provided with a driving gear. The driving gear is engaged with a gear ring sleeved on the vertical guide rod.

[0009] The CNC pavement coring machine based on ground-penetrating radar provided by the utility model has a stable structure, is easy to operate, and can realize the procedural and standardized pavement coring operation. Before coring, it first performs radar ground exploration to determine the pavement structure, avoids blind coring, and minimizes damage to the overall pavement structure; when coring, a CNC method is used to standardize the coring operation, accurately control the coring motor speed, coring descent rate, coring depth, etc., to improve the consistency and representativeness of coring, and provide an accurate reference basis for subsequent pavement paving and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION
[0011] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and a detailed implementation method and specific working process are given. However, the protection scope of the present invention is not limited to the following embodiment.
[0012] like Figure 1 As shown, the CNC pavement coring machine based on ground penetrating radar described in the present invention includes a loading plate 1, a locking moving wheel 2 is installed at each of the four corners of the bottom, and a pair of vertical poles 3 and a pair of vertical guide rods 4 are installed on the top.
[0013] Among them, the vertical pole 3 is located at one end of the loading plate and is connected by a horizontal push handle 5; the vertical guide rod 4 is spaced apart from the vertical pole 3, and the two vertical guide rods 4 are used to connect to the lifting seat 6, on which the core drill bit 8 driven by the first rotary motor 7 is installed. Normally, the lifting seat 6 is set along the mid-vertical line of the horizontal push handle 5 to maintain the stability of the device. In order to control the height of the lifting seat 6, an outward-extending fixed seat 9 is provided at the top of the vertical guide rod 4 near the horizontal push handle 5. The fixed seat 9 is equipped with an electro-hydraulic push rod 10, and the piston rod of the electro-hydraulic push rod 10 is connected to the lifting seat 6. In order to ensure the smooth progress of the sampling work, a detection sampling port 11 is opened on the loading plate 1 below the core drill bit 8. A ground penetrating radar 12 rotatably connected to the vertical guide rod 4 is also provided between the detection sampling port 11 and the core drill bit 8.
[0014] The GPR 12 is connected to one of the vertical guide rods 4 via a rotating mechanism. This mechanism includes a second rotary motor 13 mounted on the carrier plate 1. A driving gear 14 is mounted on the rotating shaft of the second rotary motor 13. This driving gear 14 meshes with a gear ring 15 sleeved on the vertical guide rod 4. The gear ring 15 is rotationally connected to the vertical guide rod 4 via a bearing. The GPR 12 is connected to the gear ring 15 via a horizontal support rod 16. When the second rotary motor 13 is activated, the horizontal support rod 16 rotates forward or reverse, causing the GPR 12 to reach above or leave the detection sampling port 11.
[0015] The above-mentioned fixed seat 9 is arranged near one side of the horizontal push handle 5, and a diagonal support rod 17 is installed between the fixed seat 9 and the two vertical rods 3 respectively. A control unit 18 for controlling the working status of the ground penetrating radar 12, the first rotating motor 7, the second rotating motor 13 and the electro-hydraulic push rod 10 is installed between the two diagonal support rods 17. The control unit also includes a visual touch operation panel.
[0016] Before coring the road surface, first start the ground-penetrating radar 12 through the visual touch operation panel, and use the second rotary motor 13 to rotate the ground-penetrating radar 12 to the top of the detection sampling port 11 for visual real-time detection, select the core sampling point, and determine the core sampling depth based on the radar reflection spectrum. After determining the core sampling position, fix the position of the carrier plate 1 through the locking mechanism of the movable wheel 2 to prevent shaking during the coring process, which affects the coring quality. Then, rotate the ground-penetrating radar 12 horizontally to a position that does not affect the normal operation of the coring machine drill bit 8, turn off the ground-penetrating radar 12, and then start the first rotary motor 7. Use the visual touch operation panel to set the drilling speed, depth, and descent rate of the core sampling. After reaching the target drilling depth, the core machine drill bit 8 automatically rises to complete the coring operation. Finally, turn off all switches on the equipment.
[0017] It should be noted that, in the description of the present invention, terms indicating orientation or positional relationships such as "front", "rear", "left", "right", "vertical", "horizontal", "inside", and "outside" are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.
