Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment used in tunnels, in particular to an intelligent tunnel sampling device. Background Art

[0002] In the construction of highway, railway and subway tunnels, whether it is tunnel excavation or pouring concrete and installing lining segments, it is often necessary to take samples from areas such as the tunnel top. For example, sampling the soil and rock layers at the tunnel top and understanding the geological conditions of the sampling site. Another example is that the regulatory authorities take samples of the concrete (or segments) after pouring at the tunnel top and understanding the quality of the concrete, etc.

[0003] In actual sampling, the prior art generally involves manually holding an electric sampling drill with a sampling drill bit (hollow inside the front of the drill bit) at the front end to drill and sample the sampling area (the sampling drill bit drills, and the soil, rock or concrete in the sampling area enters the hollow part of the drill bit to complete the sampling). In the above-mentioned operation mode, when sampling the area located on the side wall of the tunnel, due to the low height, the operator can still perform normal sampling by standing on a high stool, etc. However, when sampling the area at a higher height at the top of the tunnel, due to the limited height of the person, the tools required for climbing are relatively high, which not only brings inconvenience to the operation, but also the operator standing in a higher area to work has a greater safety risk (such as falling due to excessive height, etc.). Or, when sampling the top of the tunnel, since people need to look up and lift the sampling drill to drill and sample, this is more inconvenient than sampling the side wall of the tunnel, and the sampling time is longer, and there is a disadvantage of high labor intensity for the operator (the sampling drill has downward gravity). Finally, sampling on the top of the tunnel is a manual operation, and the distance between the operator and the sampling area is close, and the dust generated by sampling will affect the health of the operator. Based on the above, it is particularly necessary to provide a device that can perform intelligent sampling on the top of the tunnel. Summary of the invention

[0004] In order to overcome the disadvantages of the existing tunnel top sampling, which is inconvenient to operate, high labor intensity and health impact of the staff due to the use of manual handheld sampling drill for sampling, the present invention provides a convenient-to-use sampling operation that can be carried out on-site by hand pushing or the like. In application, the operator does not need to work at height, and the operator can control the sampling drill to rise or fall in height, turn left or back by remote control on the ground, perform non-manual sampling operations at different heights and positions on the top of the arc tunnel, and can sample the tunnel sidewalls as needed. The sampling drill can also be controlled to drill in and out during sampling, thereby bringing convenience to the operator, reducing safety risks, and reducing the impact of dust on the operator's health.

The first power output terminals 3 and 4 of the voltage stabilizer A and the power input terminals of the wireless receiving mechanism, the 1 and 3 pins of the wireless receiving circuit modules A1, A2, and A3, and the power input terminals of the camera SX and the display screen P are connected by wires. The second power output terminals 5 and 6 of the voltage stabilizer A and the two control power input terminals of the relay J3, J4, J5, J6, J7, and J8 of the DC control power input terminal of the wireless receiving mechanism are connected by wires. The two normally open contact ends of the relays J1 and J2 at the first and second control power output ends of the wireless receiving mechanism and the two ends of the motor power input of the electro-hydraulic push rod M1 are connected via wires (the two poles of the 220V AC power supply are connected to the two control power input ends of the relays J1 and J2, one normally open contact of the relay J1 is connected to one of the terminals of the motor capacitor, the other normally open contact of the relay J1 is connected to one end of the motor winding, one normally open contact of the relay J2 is connected to the other terminal of the motor capacitor, and the other normally open contact of the relay J2 is connected to one end of the motor winding). The two normally open contact ends of the relays J3 and J4 at the third and fourth control power output ends of the wireless receiving mechanism and the positive and negative and negative and positive power input ends of the motor reduction device M2 of the left and right adjustment device are connected via wires.

The video output terminal of the camera SX and the video input terminal of the display screen P are connected via a video cable.

[0022] Figure 1 , 2As shown in Figure 3, since all the components of the present invention are installed on the upper part of the mobile vehicle 3 (with wheels 1), it can be transported to any position in the tunnel for operation. When arriving at the operation area, the operator rotates the handles 95 of the four vehicle fixing equipment clockwise respectively, so that the rotating disks 94 of the four vehicle fixing equipment respectively drive the screw rod 92 and the contact plate 93 downward, and the contact plate 93 of the four vehicle fixing equipment is no longer adjusted after contacting the ground; after adjustment, since the lower end of the contact plate 93 of the four vehicle fixing equipment is in close contact with the ground (the contact surface becomes larger, and the lower end of the contact plate is in close contact with the ground horizontally, it can prevent the vehicle body from shaking during drilling and sampling), it can prevent the overall shaking of the trolley during subsequent drilling and sampling from affecting the drilling and sampling of the electric sampling drill body M3. After sampling, the operator rotates the handles 95 of the four vehicle fixing devices counterclockwise, so that the rotating disks 94 of the four vehicle fixing devices drive the screw rods 92 and the contact plates 93 upward respectively. The contact plates 93 of the four vehicle fixing devices are no longer adjusted after being separated from the ground by a certain distance; the contact plates and the ground are separated to prevent the subsequent movement of the trolley from being hindered. After turning on the 220V input power supply, the 1 and 2 pins of the voltage stabilizer A and the two control power input terminals of the relays J1, J2, and J9 are energized respectively. After the voltage-stabilized power supply A is energized, under the action of its internal circuit, its 3rd and 4th pins will output a stable 12V DC power supply into the 1st and 3th pins of the wireless receiving modules A1, A2, A3, as well as the power input ends of the camera SX and the display screen P. The wireless receiving modules A1, A2, A3, the camera SX, and the display screen P are in a powered working state (the camera SX captures the video data around the sampling area and transmits it to the display screen P for display); at the same time, the 5th and 6th pins of the voltage-stabilized power supply will output a 24V DC power supply into the two control power input ends of the relays J3, J4, J5, J6, J7, and J8.

[0023] Figure 1 , 2As shown in 3, when sampling, the operator combines the video captured by the camera SX with the display screen P (used in combination with direct viewing by people. The display screen is mainly used for sampling on the top of the tunnel when there is a lot of dust. In this way, the operator does not need to look up to watch and cause dust to fall into the eyes). When the electric sampling drill body M3 needs to rise, the operator presses the first button S1 of the wireless transmitting circuit module A4, so the wireless transmitting circuit module A4 transmits the first wireless closing signal. After the wireless receiving circuit module A1 receives the first wireless closing signal, its 4th pin will output a high level. The high level enters the base of the NPN transistor Q1 through the voltage reduction and current limiting of the resistor R1. The collector of the NPN transistor Q1 is turned on to output a low level and enter the negative power input terminal of the relay J1. The relay J1 is energized to attract its two control power input terminals and two normally open contact terminals to be closed respectively. Since the two poles of the 220V AC power supply are respectively connected to the two control power input terminals of the relay J1, a normally open contact of the relay J1 is connected to one of the wiring terminals of the motor capacitor of the electro-hydraulic push rod M1, and the other normally open contact of the relay J1 is connected to one end of the motor winding, the motor shaft of the electro-hydraulic push rod M1 will rotate clockwise at this moment. Under the action of the internal mechanism of the electro-hydraulic push rod M1, the piston rod of the electro-hydraulic push rod M1 drives the support plate 51 and the upper end thereof including the electric sampling drill body M3 to rise in height, approaching the top of the tunnel. When the electric sampling drill body M3 rises to the required height, the operator presses the first button S1 of the wireless transmitting circuit module A4 again, and the wireless transmitting circuit module A4 transmits the first wireless open-circuit signal. After receiving the first wireless open-circuit signal, the 4th pin of the wireless receiving circuit module A1 no longer outputs a high level, and then the NPN transistor Q1 is cut off, and the relay J1 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively, so that the electro-hydraulic push rod M1 no longer drives the electric sampling drill body M3 to rise in height (the maximum height can be raised to 1.5m, and the electro-hydraulic push rod M1, the electric sampling drill body M3, the mobile trolley 3, etc. have a certain height, so it can safely meet the sampling height requirements of the tunnel top), and prepares for drilling and sampling. In actual situations, when subsequent sampling is completed and needs to be transported, in order to facilitate transportation, the operator presses the second button S2 of the wireless transmitting circuit module A4, so that the wireless transmitting circuit module A4 transmits a second wireless closing signal. After the wireless receiving circuit module A1 receives the second wireless closing signal, its 5th pin will output a high level, and the high level enters the base of the NPN transistor Q2 through the voltage reduction and current limiting of the resistor R2. The collector of the NPN transistor Q2 is turned on to output a low level and enter the negative power input terminal of the relay J2. The relay J2 is energized and its two control power input terminals and two normally open contact terminals are closed respectively.Since the two poles of the 220V AC power supply are respectively connected to the two control power input terminals of the relay J2, one normally open contact of the relay J2 is connected to the other terminal of the motor capacitor of the electro-hydraulic push rod M1, and the other normally open contact of the relay J2 is connected to one end of the motor winding, the motor shaft of the electro-hydraulic push rod M1 will rotate counterclockwise at this moment. Under the action of the internal mechanism of the electro-hydraulic push rod M1, the piston rod of the electro-hydraulic push rod M1 drives the support plate 51 and the upper end thereof including the electric sampling drill body M3 to descend in height, and the overall height can be lowered to 1.5m, which is convenient for subsequent transportation after the sampling is completed. When the electric sampling drill body M3 is lowered to the required height, the operator presses the second button S2 of the wireless transmitting circuit module A4 again, and the wireless transmitting circuit module A4 transmits a second wireless open-circuit signal. After the wireless receiving circuit module A1 receives the second wireless open-circuit signal, its 5th pin no longer outputs a high level, and then the NPN transistor Q2 is cut off, and the relay J2 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively opening the circuit. In this way, the electro-hydraulic push rod M2 no longer drives the electric sampling drill body M3 to descend in height, and then the present invention can be conveniently transported to other operating areas, or conveniently transported back to the equipment room after sampling is completed.

[0024] Figure 1 , 2As shown in Figure 3, when the electric sampling drill body M3 rises to a height close to the operation point, the operator presses the third button S3 of the wireless transmitting circuit module A5 in conjunction with the video captured by the camera SX displayed on the display screen P, and the wireless transmitting circuit module A5 transmits the third wireless closing signal. After the wireless receiving circuit module A2 receives the third wireless closing signal, its 6th foot will output a high level, and the high level enters the base of the NPN transistor Q7 through the resistor R7 to reduce the voltage and limit the current. The NPN transistor Q7 conducts and the collector outputs a low level and enters the negative power input terminal of the relay J7. The relay J7 is energized to attract its two control power input terminals and two normally open contact terminals to close respectively. Since the two normally open contact terminals of the relay J7 and the positive and negative power input terminals of the two sets of electric push rods M5 of the support mechanism are respectively connected through wires, the motor shafts of the two sets of electric push rods M5 will rotate clockwise at this moment, and under the action of the internal mechanisms of the two sets of electric push rods M5, the piston rods of the two sets of electric push rods M5 push the upper plate 111 to rise in height. After the piston rods of the two sets of electric push rods M5 push the upper plate 111 to rise to a height and contact the top of the tunnel located on the front and rear sides of the electric sampling drill body M3, since the upper end of the upper plate has an anti-skid rubber block, the anti-skid rubber block on the upper plate can play a supporting and fixing role after effectively contacting the top of the tunnel, that is, the upper and lower ends of the present invention are effectively fixed between the top and the lower end of the tunnel, preventing the electric sampling drill body M3 from shaking during subsequent drilling and sampling and causing interference to the sampling. In order to ensure that the rubber blocks of the upper plates 111 of the piston rods of the two sets of electric push rods M5 can contact the top of the tunnel, the present invention distributes the moving vehicle 3 and the tunnel longitudinally before each sampling, ensuring that the piston rods of the two sets of electric push rods M5 are also distributed longitudinally with the tunnel, and after the height is raised, the contact plates at the upper ends of the piston rods of the two sets of electric push rods M5 can contact the top of the tunnel at the same time. When the piston rods of the two sets of electric push rods M5 push the upper plate 111 to rise and contact the tunnel top located on the front and rear sides of the electric sampling drill body M3, the operator presses the third button S3 of the wireless transmitting circuit module A5 again, so that the wireless transmitting circuit module A5 transmits the third wireless open-circuit signal. After the wireless receiving circuit module A2 receives the third wireless open-circuit signal, its 6th foot no longer outputs a high level, and then the NPN transistor Q7 is cut off, and the relay J7 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively, so that the piston rods of the two sets of electric push rods M5 no longer push the upper plate 111 to rise (the maximum rise height is 300mm, under the premise that the piston rod of the electric push rod 103 is at the lower dead point, the piston rods of the two sets of electric push rods M5 are higher than the upper end height of the sampling drill of the electric sampling drill body M3 after ascending to the dead point, so it can safely meet the sampling height requirements of the tunnel top), ready for drilling and sampling.In actual situations, when the subsequent sampling is completed and needs to be transported, the operator presses the fourth button S4 of the wireless transmitting circuit module A5, so that the wireless transmitting circuit module A5 transmits the fourth wireless closing signal. After the wireless receiving circuit module A2 receives the fourth wireless closing signal, its 7th foot will output a high level, and the high level enters the base of the NPN transistor Q8 through the resistor R8 to reduce the voltage and limit the current. The NPN transistor Q8 is turned on and the collector outputs a low level to enter the negative power input terminal of the relay J8. The relay J8 is energized to attract its two control power input terminals and two normally open contact terminals to close respectively. Since the two normally open contact terminals of the relay J8 and the negative and positive power input terminals of the two sets of electric push rods M5 of the supporting mechanism are respectively connected through wires, the motor shafts of the two sets of electric push rods M5 will rotate counterclockwise at this moment. Under the action of the internal mechanisms of the two sets of electric push rods M5, the piston rods of the two sets of electric push rods M5 drive the upper plate 111 to decrease in height and to open the distance from the top of the tunnel. After the upper plate 111 is lowered to a certain height, the operator presses the fourth button S4 of the wireless transmitting circuit module A5 again, and the wireless transmitting circuit module A5 transmits a fourth wireless open-circuit signal. After the wireless receiving circuit module A2 receives the fourth wireless open-circuit signal, its pin 7 no longer outputs a high level, and then the NPN transistor Q8 is cut off, and the relay J8 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively opening the circuit. In this way, the piston rods of the two sets of electric push rods M5 no longer drive the upper plate 111 to descend in height, and are ready for transportation or operation at the next work point.

[0025] Figure 1 , 2As shown in FIG. 3, when the piston rods of the two sets of electric push rods M5 push the upper plate 111 to rise and contact the tunnel top located on the front and rear sides of the electric sampling drill body M3, the operator presses the first button S1 of the wireless transmitting circuit module A6 in combination with the video shot by the camera SX displayed on the display screen P, so that the wireless transmitting circuit module A6 transmits the first wireless closing signal. After the wireless receiving circuit module A3 receives the first wireless closing signal, its 4th pin will output a high level, and the high level enters the base of the NPN transistor Q9 through the resistor R9 to reduce the voltage and limit the current. The NPN transistor Q9 conducts and the collector outputs a low level to the negative power input terminal of the relay J9, and the relay J9 is energized to attract its two control power input terminals and two normally open contact terminals to close respectively. Since the two normally open contact terminals of the relay J9 (the control power input terminal and the two poles of the 220V power supply are connected respectively) are connected to the two power input terminals of the electric sampling drill body M3, the electric sampling drill body M3 will be powered at this moment to drive the drill bit 41 to rotate and prepare for sampling. When the subsequent electric sampling drill body M3 completes sampling, the operator combines the video captured by the camera SX displayed on the display screen P and presses the first button S1 of the wireless transmitting circuit module A6 again, whereupon the wireless transmitting circuit module A6 transmits the first wireless open-circuit signal. After the wireless receiving circuit module A3 receives the first wireless open-circuit signal, its 4th pin stops outputting a high level, and then the NPN transistor Q9 is cut off, the relay J9 loses power and no longer attracts, and the electric sampling drill body M3 no longer moves the drill bit 41 to rotate, completing the sampling work (after the actual sampling is completed, the drill bit must be kept rotating before it is completely withdrawn from the tunnel, so that the drill bit will slowly withdraw from the tunnel when the electric sampling drill body M3 descends in height, and will be closed after it is completely withdrawn).

[0026] Figure 1 , 2As shown in Figure 3, when the drill bit of the electric sampling drill body M3 rotates, the operator presses the first button S1 of the wireless transmitting circuit module A5 in conjunction with the video shot by the camera SX displayed on the display screen P, so that the wireless transmitting circuit module A5 transmits the first wireless closing signal. After the wireless receiving circuit module A2 receives the first wireless closing signal, its 4th pin will output a high level, and the high level enters the base of the NPN transistor Q5 through the voltage reduction and current limiting of the resistor R5. The collector of the NPN transistor Q5 is turned on and the output low level enters the negative power input terminal of the relay J5. The relay J5 is energized and its two control power input terminals and two normally open contact terminals are closed respectively. Since the two normally open contact ends of the relay J5 and the positive and negative power input ends of the electric push rod M4 of the left and right adjustment device are respectively connected through wires, the motor shaft of the electric push rod M4 will rotate clockwise at this moment. Under the action of the internal mechanism of the electric push rod M4, the piston rod of the electric push rod M4 pushes the electric sampling drill body M3 to gradually rise in height. In this way, the electric sampling drill body M3 will drill and sample the working area through the drill bit 41 at the rising height. In actual situations, the operator needs to control the gap when controlling the electric sampling drill body M3 to rise in height and drilling and sampling the working area through the drill bit. That is to say, when the load of the electric sampling drill body M3 increases and the noise generated during operation is obviously wrong (the sound of the electric sampling drill body M3 will change when it is under a large load, which is common knowledge among operators), it is necessary to temporarily control the electric push rod M4 to stop working, and the electric sampling drill body M3 continues to work and does not rise in height temporarily. After the motor sound of the electric sampling drill body M3 returns to normal, the electric push rod M4 is controlled to work again to push the electric sampling drill body M3 to rise in height until all sampling work is completed. During operation, when the electric sampling drill body M needs to stop working, the operator combines the display screen P to display the video shot by the camera SX, and presses the first button S1 of the wireless transmitting circuit module A5 again, so that the wireless transmitting circuit module A5 transmits the first wireless open-circuit signal. After the wireless receiving circuit module A2 receives the first wireless open-circuit signal, its 4th pin will stop outputting a high level, and then the NPN transistor Q5 will be cut off, the relay J5 will lose power and no longer be attracted, and then the electric push rod M4 will no longer be powered to work. When sampling is completed and the drill bit 42 needs to be withdrawn from the tunnel, the operator presses the second button S2 of the wireless transmitting circuit module A5 in conjunction with the video captured by the camera SX displayed on the display screen P. Then, the wireless transmitting circuit module A5 transmits a second wireless closing signal. After the wireless receiving circuit module A2 receives the second wireless closing signal, its 5th pin will output a high level. The high level enters the base of the NPN transistor Q6 through the voltage reduction and current limiting of the resistor R6. The collector of the NPN transistor Q6 is turned on to output a low level and enter the negative power input terminal of the relay J6. The relay J6 is energized to attract its two control power input terminals and two normally open contact terminals to be closed respectively.Since the two normally open contact ends of the relay J6 and the negative and positive power input ends of the electric push rod M4 of the left and right adjustment device are connected by wires, the motor shaft of the electric push rod M4 will rotate counterclockwise at this moment. Under the action of the internal structure of the electric push rod M4, the piston rod of the electric push rod M4 drives the sampling drill body M3 to descend in height, so that the drill bit of the electric sampling drill body M3 will withdraw from the tunnel. When the drill bit 41 withdraws from the tunnel, the operator combines the video captured by the camera SX displayed on the display screen P and presses the second button S2 of the wireless transmission circuit module A5 again, so that the wireless transmission circuit module A5 transmits the second wireless open circuit signal. After the wireless receiving circuit module A2 receives the second wireless open circuit signal, its 5th foot will stop outputting a high level, and then the NPN transistor Q6 is cut off, the relay J6 loses power and no longer attracts, so the electric push rod M4 will no longer be powered to work.

[0027] Figure 1 , 2As shown in Figure 3, in the present invention, before the electric sampling drill body M3 is drilled, it can not only drill into the vertical part of the upper end of the tunnel of the electric sampling drill body M3, but also drill into the top of the tunnel at any position of the left and right sides. In this way, if it is found that there is a deviation between the vertical upper end of the drill bit and the sampling part (left and right deviation) after the present invention is fixed, it is not necessary to re-move the vehicle body, etc., and the orientation of the drill bit 41 can be directly adjusted. When the drill bit angle needs to be adjusted to the left, the operator presses the third button S3 of the wireless transmitting circuit module A4, so that the wireless transmitting circuit module A4 transmits the third wireless closing signal. After the wireless receiving circuit module A1 receives the third wireless closing signal, the 6th pin will output a high level, and the high level enters the base of the NPN transistor Q3 through the resistor R3 to reduce the voltage and limit the current. The NPN transistor Q3 conducts the collector to output a low level and enters the negative power input terminal of the relay J3. The relay J3 is energized to attract its two control power input terminals and two normally open contact terminals to close respectively. Since the two normally open contact ends of the relay J3 and the positive and negative power input ends of the motor reducer M2 of the left and right adjustment devices are connected via wires respectively, at this moment the motor reducer M2 will be powered and its power output shaft will drive the electric push rod M4 and the electric sampling drill body M3 to rotate leftward by an angle. When the electric sampling drill body M3 is adjusted to the left angle, the operator presses the third button S3 of the wireless transmitting circuit module A4 again, so that the wireless transmitting circuit module A4 transmits the third wireless open-circuit signal. After the wireless receiving circuit module A1 receives the third wireless open-circuit signal, its 6th foot no longer outputs a high level, and then the NPN transistor Q3 is cut off, and the relay J3 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively, so that the motor reduction device M2 no longer drives the electric sampling drill body M3 to rotate to the left, and the operator can subsequently perform drilling operations (when the motor reduction device M2 drills and samples at a left angle, the relative position of the piston rod of the electric push rod M4 when it moves upward is to move forward to the left front end, pushing the rotating motor reduction device M4 drill bit to drill). When the drill bit angle needs to be adjusted to the right, the operator presses the fourth button S4 of the wireless transmitting circuit module A4, and the wireless transmitting circuit module A4 transmits the fourth wireless closing signal. After the wireless receiving circuit module A1 receives the fourth wireless closing signal, the 7th pin will output a high level, and the high level enters the base of the NPN transistor Q4 through the resistor R4 to reduce the voltage and limit the current. The NPN transistor Q4 conducts and the collector outputs a low level and enters the negative power input terminal of the relay J4. The relay J4 is energized to attract its two control power input terminals and two normally open contact terminals to close respectively. Since the two normally open contact terminals of the relay J4 and the negative and positive power input terminals of the motor reduction device M2 of the left and right adjustment device are connected by wires respectively, at this moment, the motor reduction device M4 will be energized to work, and its power output shaft drives the electric push rod M4 and the electric sampling drill body M3 to rotate to the right.When the electric sampling drill body M3 is adjusted to the right angle, the operator presses the fourth button S4 of the wireless transmitting circuit module A4 again, whereupon the wireless transmitting circuit module A4 transmits the fourth wireless open-circuit signal. After receiving the fourth wireless open-circuit signal, the 7th foot of the wireless receiving circuit module A1 no longer outputs a high level, and then the NPN transistor Q4 is cut off, and the relay J4 loses power and no longer attracts its two control power input terminals and two normally open contact terminals, respectively opening the circuit. In this way, the motor reduction device M2 no longer drives the electric sampling drill body M3 to rotate to the right, and the operator can subsequently perform drilling operations (when the motor reduction device M2 is drilling and sampling at a right angle, the relative position of the piston rod of the electric push rod M4 when it moves upward is to move forward to the right front end, pushing the rotating motor reduction device M4 drill bit to drill).

[0028] Figure 1 , 2 As shown in Figure 3, since all the components of the present invention are installed on the upper part of the mobile vehicle 3, it can be transported to any position in the tunnel for operation. Since the piston rod of the electro-hydraulic push rod 5 can adjust the height, the height of the present invention is not high during transportation, and it is more convenient to use. After arriving at the site, the vehicle can be adjusted to fix the equipment, so that the lower end contact plate 93 of the four sets of vehicle fixing equipment can be in contact with the ground, which prevents the impact of the shaking of the entire equipment on the drilling sampling during the drilling operation. In the application of the present invention, there is no need for operators to climb up to work. The operator can display the video near the sampling drill on the display screen on the ground, and control the sampling drill to rise or fall in height through remote control, and turn left or back. In this way, non-manual sampling operations can be performed at different heights and different positions at the top of the tunnel, and sampling can be performed on the side wall of the tunnel as needed. During sampling, the sampling drill can also be controlled to drill in and out, achieving the purpose of intelligent control. The present invention is particularly suitable for sampling in the top area of ​​the tunnel, which brings convenience to the operator, reduces risks, and reduces the impact of dust on the operator's health. The resistance of resistors R1, R2, R3, R4, R5, R6, R7, R8, and R9 is 1K; the model of NPN transistors Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, and Q9 is 9013; and the relays K1, K2, K3, K4, K5, K6, K7, K8, and K9 are DC12V relays.
