[0002] In construction projects, drilling sampling is a common soil and rock exploration method used to obtain information on the physical and mechanical properties of underground materials. This information is crucial for engineering design and construction. Drilling sampling can be performed using different methods, the most common of which are core sampling and soil sampling. Core sampling is generally used in rock exploration. By rotating the drill bit and core drilling tool, a rock ring sample is removed and kept intact. Soil sampling uses special sampling tools, such as sampling tubes, to remove soil samples. Existing soil sampling processes mostly use small portable drilling equipment, which uses a motor to drive the sampling tube for sampling. When workers grasp the equipment, they need to distract themselves and use extra manpower to apply pressure to fix the overall structure. This is extremely inconvenient to use and the sampling results are very unstable. Utility Model Content

[0024] Example:

[0025] Figure 1-Figure 4 The present invention shows a drilling device for detection, including a base 1, a lifting assembly and a drive motor 2. The lifting assembly is connected to the base 1. The lifting assembly includes a lifting box 4. The drive motor 2 is connected to the lifting box 4 through a rotating ring 21. The drive motor 2 is welded to the rotating ring 21. The output end of the drive motor 2 is connected to a sampling tube 3. The sampling tube 3 is vertically arranged. The base 1 can be fixed on the ground or various smooth metal plates. The staff does not need to be distracted to fix the entire device. The sampling tube 3 can always remain vertical for drilling sampling. The sampling tube 3 is usually of standard size. For this purpose, an extension rod 31 is equipped. The two ends are respectively connected to the sampling tube 3 and the drive motor 2. The extension rod 31 is threadedly connected to the sampling tube 3 and the drive motor 2. The drive motor 2 controls the rotation of the sampling tube 3. The direction of rotation is opposite to the direction of tightening the thread of the extension rod 31.

[0026] The base 1 includes a fixed plate 11 and a flap 12. The flap 12 is connected to the fixed plate 11 through a rotating shaft. The flap 12 has two fixing modes. The first is the overlapping mode. The flap 12 is overlapped with the fixed plate 11. External ears are added to the flap 12 and the fixed plate 11 respectively. The external ears are respectively provided with a first screw hole and a second screw hole. In the overlapping mode, the first screw hole and the second screw hole are coaxial for the screw to pass through. After the screw passes through the first screw hole and the second screw hole, it is fixed to the ground, and the entire device is firmly fixed to the ground; the second is the expansion mode. After the flap 12 is rotated, it is parallel to the fixed plate 11 and has the same height. An electromagnet 121 is added to the flap 12. The electromagnet 121 is magnetic when energized, and can fix the flap 12 and the entire device on the metal plate. There are many construction vehicles on the construction site, and the electromagnet 121 can be used to adsorb the entire device to the rear of the vehicle compartment.

[0027] The lifting assembly also includes a rack 5, and the lifting box 4 is mounted on the rack 5. An adjusting gear 41 is provided in the lifting box 4, and the adjusting gear 41 is engaged with the rack 5. The end of the adjusting gear 41 away from the rack 5 is connected to a hand crank 42. The staff rotates the hand crank 42 to rotate the adjusting gear 41. The adjusting gear 41 cooperates with the rack 5 to drive the lifting box 4 to move up and down. The rack 5 is made of hard metal and is not easy to bend. It can bear the weight of the lifting box 4 and the drive motor 2 connected thereto.

[0028] A lifting rod 51 is also provided in the rack 5. One end of the lifting rod 51 is connected to the inside of the rack 5, and the other end is connected to the fixed plate 11. The lifting rod 51 can be retracted into the inside of the rack 5 or extended out of the rack 5. Under the premise that the base 1 is fixed, the height of the rack 5 can be adjusted.

[0029] A limit column is provided on one side of the lifting box 4, and the rotating ring 21 is sleeved on the limit column. A stop is provided on the limit column, and the rotating ring 21 is also equipped with a limit pin 22. The limit pin 22 can be inserted into and pass through the rotating ring 21 and abut against the limit column, thereby hindering the rotation of the rotating ring 21, so that the rotating ring 21 and the drive motor 2 fixed thereto are fixed at a certain angle.

[0030] A height tightening screw 52 is installed on the rack 5. When the height tightening screw 52 is tightened, it abuts against the lifting rod 51 inside the rack 5, preventing the lifting rod 51 from moving relative to the rack 5, so that the height of the rack 5 is fixed.

[0031] A fixing ring 6 is provided on the fixing plate 11, and a lifting rod 51 is rotatably connected to the fixing plate 11 and is arranged at the center of the fixing ring 6. When the lifting rod 51 is retracted into the rack 5, the rack 5 abuts against the fixing plate 11 and is also located at the center of the fixing ring 6. An angle fastening screw 61 is provided on the fixing ring 6. The angle fastening screw 61 can pass through the fixing ring 6 and abut against the lifting rod 51, thereby limiting the rotation of the lifting rod 51 and fixing the rotation angle of the sampling tube 3.

[0032] Working principle:

[0033] When the utility model is in normal use, it has two fixing modes. One is to fix it on the ground. At this time, the flap 12 is overlapped with the fixed plate 11, and the outer ears of the flap 12 and the fixed plate 11 are coaxial. The staff passes the screw through the first screw and the second screw hole to fix the base 1 and the entire device to the ground; the second is to fix it on the rear compartment of the construction vehicle. At this time, the flap 12 is rotated to be parallel to the fixed plate 11, and then fixed by bolts, and then the flap 12 is attached to the smooth metal surface of the compartment, the rack 5 is in contact with the ground, and the electromagnet 121 is started to fix the flap 12 and the entire device to the compartment. At this time, the sampling tube 3 needs to be adjusted to be vertically facing the ground by rotating the rotating ring 21.

[0034] After the entire device is fixed by the base 1, the hand crank 42 is turned to control the rotation of the adjustment gear 41, so that the lifting box 4 can move up and down along the rack 5 to a suitable position. At this time, the sampling tube 3 is close to the soil to be sampled, and the drive motor 2 is started to rotate the sampling tube 3. The hand crank 42 is then turned to control the sampling tube 3 to slowly descend for drilling sampling. After the sampling is completed, the hand crank 42 is shaken to rotate in the opposite direction to lift the sampling tube 3.

[0035] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by utilizing the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
