When in use, the first motor 12 drives the rotating shaft 14 to rotate, and the first bevel gear 15 rotates accordingly and drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the ball screw 17 to rotate and drives the nut seat 18 to move along the axis of the ball screw 17, thereby driving the drill barrel 7 to move in the direction of the axis of the ball screw 17. The rotation drive mechanism 20 drives the drill barrel 7 to rotate to realize drilling of the drill barrel 7. The rotation of the rotating shaft 14 drives the gear 21 to rotate, thereby driving the rack 22 to move. It should be noted that the moving speed of the rack 22 is consistent with the moving speed of the nut seat 18, and the gear 21 can be detachably installed to realize the selective movement of the rack 22.

When the second through hole 27 of the rack 22 is located at the upper part of the cross bar 23, the second through hole 27 of the cross bar 23 and the second through hole 27 of the rack 22 correspond vertically, and a plug pin 28 is inserted between the two to achieve limited fixation of the rack 22.

[0035] like Figure 3-5 As shown: In the initial state Figure 3 As shown: the nut seat 18 is located at one end close to the rotating shaft 14, and the baffle 8 is located at the drilling end of the drill tube 7, which is the retracted state of the detection mechanism 2 and the state to be drilled. After being retracted, the footprint is small and it is convenient for storage and transfer; when drilling, Figure 4 As shown: the bolt 26 is removed, the gear 21 is moved along the axis direction of the rotating shaft 14 to cancel the meshing with the rack 22, and the rack 22 is fixed by the latch 28, the first motor 12 is started to drive the drill tube 7 to move for drilling, the rack 22 is fixed and the baffle 8 remains in place, the sampling part of the building body enters the interior of the drill tube 7 and the end is always in contact with the baffle 8, and the baffle 8 is limited to ensure the integrity of the sampling structure of the building body, so as to avoid the end of the building body sample that first enters the interior of the drill tube 7 to spread out and affect the subsequent detection of the sample; when the drilling sampling is completed and the sample is collected, as shown in FIG. Figure 5As shown: the gear 21 is fixedly mounted on the rotating shaft 14 and meshes with the rack 22. The latch 28 is removed to cancel the limitation on the rack 22. The first motor 12 is reversed to drive the drill tube 7 to move in the opposite direction and move out of the building body. The rack 22 moves synchronously, and the baffle 8 moves synchronously with the drill tube 7 to keep the building body sample in a limited position and keep the building body sample in the drill tube 7 unchanged. The movement of the baffle 8 and the movement of the drill tube 7 use the same power source, which reduces the equipment cost, and the setting of the baffle 8 ensures the integrity of the sample.

[0036] like Figure 7 As shown: the rotation drive mechanism 20 includes a shield, a pressure sensor 29, a driven gear 30, a second motor 31 and a driving gear 32.

The second motor 31 drives the driving gear 32 to rotate, and the driving gear 32 drives the driven gear 30 meshing with it to rotate, and the pressure sensor 29 rotates accordingly, thereby driving the drill barrel 7 to rotate, and rotary drilling is achieved under the movement of the drill barrel 7. The pressure sensor 29 is used to detect the reaction force of the drill barrel during drilling. The pressure sensor 29 is connected to the main controller 6 for information transmission, and is used to collect and store real-time data detected by the pressure sensor 29.

[0037] like Figure 8 As shown: the end of the rack 22 close to the baffle 8 is connected to the second connecting sleeve 35, and the end of the second connecting sleeve 35 away from the rack 22 is detachably connected to the damping telescopic rod 36, and the detachable connection includes but is not limited to the use of threaded connection, the external limiting sleeve of the damping telescopic rod 36 is provided with a spring 37, and the end of the damping telescopic rod 36 is fixedly connected to the baffle 8. The setting of the damping telescopic rod 36 and the spring 37 makes the baffle 8 limit the building main body sample with elasticity to avoid hard limiting damage to the device.

[0038] like Fig. 9 and 10As shown: the side wall of the drill tube 7 is cut axially from the drilling end to the other end to form an opening 39 and a sealing plate 38. Slots 40 are provided on both sides of the opening 39 in the side wall of the drill tube 7. Plug plates 41 adapted to be plugged in with the slots 40 are provided on both sides of the sealing plate 38. The plug plates 41 of the sealing plate 38 are plugged in the slots 40. The sealing plate 38 covers the opening 39 to ensure that the integrity of the side wall of the drill tube 7 does not affect the drilling sampling. The setting of the sealing plate 38 is plugging, and after the sampling is completed, the sealing plate 38 is disassembled to leak out the sample. The sample can be placed in the drill tube 7 for observation and the integrity of the sample can be ensured, so as to accurately observe the composition and thickness of each layer of the sample.

[0039] like Figure 2 As shown: a placement slot is provided on the storage plate of the mobile vehicle 1, and a measuring ruler 11 is placed in the placement slot for use in on-site length measurement.

[0040] like Figure 2 As shown: the telescopic driving mechanism 3 includes a sealed box body 42, a threaded rod 43, a limit light rod 44 and a knob 45. The sealed box body 42 is fixedly installed on one side of the storage plate, the threaded rod 43 is threadedly installed in the sealed box body 42 and both ends pass through the sealed box body 42, the axis of the threaded rod 43 is parallel to the side of the sealed box body 42 installed on the storage plate, the limit light rod 44 is inserted into the sealed box body 42 and both ends pass through the sealed box body 42, the axis of the limit light rod 44 is parallel to the axis of the threaded rod 43, the knob 45 is coaxially fixedly connected to one end of the threaded rod 43, and the other end of the threaded rod 4 is rotatably installed with a slide rail 4, the slide rail 4 is parallel to the adjacent side of the storage plate and the adjacent side of the sealed box body 42 installed on the storage plate, the limit light rod 44 is fixedly connected to the slide rail 4, the length direction of the limit plate 5 is parallel to the guide of the slide rail 4, and the limit plate 5 is slidably installed on the slide rail 4.

[0041] The device uses a drill tube 7 for detection and sampling. After sampling, the sample is taken out, and slurry is introduced into the drill tube 7. The slurry includes but is not limited to cement slurry. The drill tube 7 is extended into the drill hole of the building body, the rack 22 is fixed to keep the baffle 8 in place, and the first motor 12 is started to drive the drill tube 7 to move out of the drill hole of the building body. Under the limit of the baffle 8, the slurry is filled in the drill hole of the building body to complete the filling of the drill hole; The limit plate 5 is slidably installed with the slide rail 4. When the drill tube 7 is drilling, the sliding limit plate 5 is not opposite to the drill tube 7. When the building body is drilled through, the drill tube 7 is prevented from contacting the limit plate 5. When filling the slurry, the limit plate 5 is pulled to cover the end of the drill hole of the building body, so that the slurry filling can be formed in one time and subsequent manual repair can be avoided.

[0042] The present invention uses a drill tube 7 to drill and take samples, and cooperates with a pressure sensor 29 to detect the strength of the building body during drilling. The present invention also provides an algorithm flow for drilling to detect the strength of the building body: Specifically, during the drilling detection process, the main data include drilling depth D, drill tube reaction force F and rotation speed ω; Assuming that the drill tube reaction force F is related to the compressive strength σc of the building body, the drill tube reaction force F can be approximated as: F = σc⋅A; Where: A is the contact area of ​​the drill bit; The formula for the relationship between the drill barrel reaction force F and the drilling depth D, the rotation speed ω and the compressive strength σc is: F = α⋅σc⋅A⋅D β ⋅ω γ ; Where: α is the proportionality coefficient, A is the contact area of ​​the drill bit, β and γ are empirical coefficients that represent the effect of depth and rotation speed on the reaction force; Using the drill tube reaction force F, the strength σc of the building body can be estimated through regression analysis or experimental data fitting, assuming that the drill tube reaction force F has a linear relationship with the compressive strength σc: σc=F / (α⋅A⋅D β ⋅ω γ ); In order to improve the accuracy of the algorithm, it is usually necessary to combine experimental data and fit the optimal α, β and γ parameters through regression analysis (such as least squares method). This step can calibrate the algorithm model.

[0043] The compressive strength of the building body can be calculated according to the algorithm, wherein different materials at different positions of the building body result in different drill tube reaction force F values ​​detected by the pressure sensor 29, and multiple corresponding strength σc values ​​are calculated according to the change of the drill tube reaction force F.

[0044] It should also be noted that the electronic control components of the device are all electrically connected to the main controller 6 and are controlled and operated by the main controller 6 .

[0045] The various mechanisms of this device cooperate with the functions of building main body strength detection, building main body sampling, building main body sample integrity observation, building main body sample layer thickness measurement, and building main body sampling. Drilled hole filling functions, and building main body sampling can also detect the density of the building main body based on the sample, etc., to further improve the accuracy of building main structure detection. For example, density detection can be achieved by measuring the volume of the sample using the drainage method.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
