DETAILED DESCRIPTION

[0028] Embodiment 1

[0029] like Figure 1-Figure 4 As shown, a highway survey geological rock and soil sampling device proposed in this embodiment includes a gantry 1, a tunneling pipe 2, a hoisting mechanism, a chassis 5, a spiral tunneling mechanism, a clamping machine and a sampling mechanism.

[0030] The hoisting mechanism is installed on the gantry 1; the hoisting mechanism is used to drive the tunneling pipe 2 to rise and fall, and the hoisting mechanism includes a rotating shaft b10, a reducer b251, a servo motor b252 and two sets of retracting and releasing components. The rotating shaft b10 is rotatably installed on the gantry 1, the reducer b251 and the servo motor b252 are installed on the gantry 1, the output shaft of the servo motor b252 is connected to the input shaft of the reducer b251, and the output shaft of the reducer b251 is connected to the rotating shaft b10. The retracting and releasing components include a reel 11 and a lifting rope 26. The reel 11 is installed on the rotating shaft b10. One end of the lifting rope 26 is fixedly wound on the winding drum 11, and the other end thereof is connected to the tunneling pipe 2; a length scale is provided on the lifting rope 26, through which the operator can easily observe the lowering depth of the tunneling pipe 2 and can more accurately determine the sampling depth of the soil; a cross bar 13 is connected to the gantry 1, and two circular rings 12 are installed on the cross bar 13, and the two lifting ropes 26 are respectively movable through the two circular rings 12, and the circular rings 12 can limit the lifting rope 26 to prevent the tunneling pipe 2 from having a large deviation during the movement.

[0031] The chassis 5 is installed at the center position of the tunneling pipe 2; the spiral tunneling mechanism is installed at the bottom end of the chassis 5; a linear drive mechanism a7 for driving the spiral tunneling mechanism to rise and fall is installed inside the chassis 5; the spiral tunneling mechanism includes a reducer a61, a servo motor a62, a spiral blade 3 and a rotating shaft a4, and a mounting seat 8 is connected to the output shaft of the linear drive mechanism a7, the reducer a61 and the servo motor a62 are installed on the mounting seat 8, the output shaft of the servo motor a62 is connected to the input shaft of the reducer a61, and the output shaft of the reducer a61 is connected to the rotating shaft a4, and the rotating shaft a4 movably passes through the bottom end of the chassis 5, and the spiral blade 3 is installed on the rotating shaft a4, and the bottom end diameter of the spiral blade 3 is larger than the outer diameter of the tunneling pipe 2.

[0032] The clamping mechanism is used to clamp the device on the inner wall of the excavation cave. The clamping mechanism includes a linear drive mechanism b17, a push plate a18 and two sets of symmetrically arranged clamping members. The linear drive mechanism b17 is installed on the inner side of the chassis 5. The push plate a18 is installed on the output shaft of the linear drive mechanism b17. The push plate a18 has a triangular cross-section with the tip facing downward. The clamping member includes a clamping plate 9, a guide rod 161, a spring a162 and an end plate 163. The guide rod 161 movably penetrates the chassis 5 and the excavation pipe 2 The end plate 163 and the clamping plate 9 are respectively connected to the inner and outer ends of the guide rod 161, and the spring a162 is sleeved and installed on the guide rod 161. The linear drive mechanism b17 drives the push plate a18 to move downward, and the push plate a18 squeezes the two end plates 163 to move outward synchronously, thereby driving the two clamping plates 9 to move. When the push plate a18 is driven to move upward, the clamping plate 9 can be automatically reset under the elastic force of the spring a162. Through the arrangement of the above structure, the excavation pipe 2 can be firmly fixed inside the cave.

[0033] The sampling mechanism is used to sample the soil inside the excavation cave. The sampling mechanism includes a plurality of sampling tubes 14 arranged side by side. The plurality of sampling tubes 14 are movable through the chassis 5 and the side wall of the excavation pipe 2. A limit ring 20 and a connecting block 22 are provided on the sampling tube 14, and the connecting block 22 and the limit ring 20 are respectively provided on the inner and outer sides of the chassis 5. A spring b23 is sleeved on the sampling tube 14. A linear drive mechanism c19 is installed on the inner side of the chassis 5. A push plate b24 is connected to the output shaft of the linear drive mechanism c19, and the cross-section of the push plate b24 is a triangular structure.

[0034] The side walls of the chassis 5 are made of copper material, which has good thermal conductivity. A plurality of coolant injection boxes 15 are arranged on the inner side of the chassis 5. A liquid inlet pipe is connected to the coolant injection box 15 to add coolant to the inside of the coolant injection box 15. A sealing cover is detachably installed on the liquid inlet pipe. Since a large number of driving devices are installed inside the chassis 5, the inner cavity temperature of the chassis 5 will be relatively high. The coolant poured into the inner side of the coolant injection box 15 can absorb the heat inside the chassis 5 to avoid continuous overheating of the inner cavity of the chassis 5. At the same time, the soil temperature deep inside is relatively low, which can assist in cooling the chassis 5.

[0035] The operator fixes the gantry 1 on the ground at the sampling location. When sampling deep geology, the operator first manually fixes the tunneling pipe 2 and presses the tunneling pipe 2 downward. During this process, the soil is excavated by the spiral tunneling mechanism. When the excavated hole is large enough to accommodate the tunneling pipe 2, the tunneling pipe 2 is released, and then the linear drive mechanism b17 is started to drive the push plate a18 to move downward. The push plate a18 drives the clamping plates 9 on both sides to move outward synchronously, so that the clamping plates 9 are clamped on the inner wall of the cave. The spiral tunneling mechanism is then driven downward by the linear drive mechanism a7 to continuously dig deep into the ground. The excavated soil is discharged to the top of the tunneling pipe 2 through the cavity between the tunneling pipe 2 and the chassis 5. Then the spiral tunneling mechanism is driven to reset upward and release the fixation of the tunneling pipe. Subsequently, the tunneling pipe 2 is continuously driven downward by the hoisting mechanism. This reciprocating process can realize the excavation of deep soil. When a certain depth is excavated, After the degree is reached, the excavation pipe 2 is driven upward by the hoisting mechanism to bring out the soil accumulated above the excavation pipe 2, and then the excavation pipe 2 is put back into the excavated cave. When sampling is performed, the linear drive mechanism c19 is started to drive the push plate b24 to move downward. The inclined surface of the push plate b24 contacts the connecting block 22, forcing the connecting block 22 to move. The connecting block 22 drives the sampling tube 14 to move outward, so that the sampling tube 14 is inserted into the soil to achieve soil sampling. Then the push plate b24 is continuously driven downward to move. When the push plate b24 is separated from the connecting block 22, the sampling tube 14 at the upper end is driven to reset under the elastic force of the spring b23 to ensure the smooth movement of the excavation pipe 2 in the cave. Then the push plate b24 is continuously driven downward to achieve the sampling work of the next sampling tube 14. The technical solution can achieve sampling of soil at different depths by setting up multiple sampling tubes 14, and the entire sampling work is compact, orderly and efficient.

[0036] Embodiment 2

[0037] like Figure 4 As shown, a highway survey geological rock and soil sampling device proposed in this embodiment, compared with the first embodiment, in this embodiment, a movable column 21 is slidably connected to the sampling tube 14, and the movable column 21 is gap-matched with the inner side of the sampling tube 14; after the sampling work is completed, the excavation tube 2 is moved out of the cave by the provided lifting mechanism, and then the soil remaining in the inner cavity of the excavation tube 2 is poured out, and then the multiple movable columns 21 are pushed to move respectively, so that the soil inside the sampling tube 14 can be squeezed out, and the movable column 21 and the sampling tube 14 are set to a gap-matched structure, so as to prevent the soil from remaining on the inner wall of the sampling tube 14, and avoid contamination of the next sample.

[0038] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
