Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction supporting detection equipment, in particular to an intelligent tunnel construction quality detection device. Background Art

[0002] In the construction of highway tunnels or railway tunnels (including subways), the quality of the tunnel secondary lining structure needs to be inspected after pouring. Among various inspection items, the surface flatness inspection of the structure is a relatively important inspection process (the apparent quality such as flatness is an indicator of completion acceptance). In actual construction, if the tunnel surface is concave or convex after pouring concrete, it will not only affect the construction quality (unsightly), but also cause erosion (for example, the concrete surface protrudes downward too much, resulting in a lower height at the top of the tunnel and a narrower width on the side, affecting driving safety), which poses a hidden danger to the safe operation of the tunnel.

[0003] In the process of inspecting the tunnel quality (structural surface flatness) by inspectors, the existing technology is to inspect the top and side quality of the tunnel by walking manually with a lighting lamp (such as a flashlight). The manual inspection method is not only time-consuming and labor-intensive, but also inconvenient for the inspectors, and is not conducive to improving the inspection efficiency. More importantly, in actual situations, since the light in the tunnel is usually not good, it is impossible to achieve full coverage inspection by manually inspecting the structural surface flatness of the tunnel by lighting. There is no doubt that there are missed inspection areas (especially affected by the sense of responsibility of the inspectors), so the quality inspection of the tunnel cannot be guaranteed. Based on the above, it is particularly necessary to provide a detection device that does not require manual inspection, can automatically perform structural surface flatness quality inspection on the top and sides of the tunnel, and can prompt the inspectors to check on site in time when tunnel quality problems are found, and can indicate the fault point. Summary of the invention

[0004] In order to overcome the disadvantages of the existing detection of the surface flatness quality of tunnel structures, that is, due to the lack of suitable equipment, manual detection will bring inconvenience to the detection personnel and cannot guarantee the detection quality, the present invention provides an intelligent tunnel construction quality detection device which does not require manual detection, can automatically detect the surface flatness quality of the tunnel top and both sides within the time preset by the detection personnel (that is, within the preset distance), can simultaneously detect whether the tunnel top and both sides are concave or convex during the detection, and can stop the movement and indicate the fault point as soon as the quality problem is detected during the detection, and can prompt the detection personnel to deal with it in time on the spot (later arrange the construction personnel to re-construct and repair), thereby bringing convenience to the detection personnel, improving the detection work efficiency, and effectively ensuring the detection quality.

The two poles of the second battery G1 and the two terminals of the second charging socket CZ1 are connected via wires respectively (when the battery G1 is out of power, the charging plug of the external 24V power charger can be inserted into the charging socket CZ1 to charge the battery G1), the positive pole of the second battery G1 is connected to one end of the second power switch S1, the other end of the second power switch S1, the negative pole of the second battery G1 and the 1st and 2nd feet of the time-controlled switch A13 at both ends of the power input of the trigger sub-circuit, and the 1st and 2nd feet of the power input of the 48 photoelectric switches A6N and A11N of the side detection circuit are connected via wires respectively, the signal output end 3 foot of the 48 photoelectric switches A6N and A11N of the side detection circuit and the positive poles of the diodes VD3 and VD4 of the two signal input ends of the trigger sub-circuit are connected via wires respectively; the two normally open contact ends of the two power output ends of the side detection circuit relay K7 and the positive and negative power input ends of the four motor reduction mechanisms MN of the two electric drive vehicles of the main vehicle body are connected via wires respectively. In the present invention, the wireless transmitting module A8 is equipped with a DC-DC power supply module A14 that converts a DC 24V to a DC 12V power supply, which can convert the input DC 24V power supply into a DC 12V power supply to supply power to the wireless transmitting module A8; the power input ends 1 and 2 of the DC-DC power supply module A14 are connected to the negative electrodes of the diodes VD1 and VD2 and the negative electrode of the battery G through wires, and the power output ends 3 and 4 of the DC-DC power supply module A14 are connected to the power input ends 1 and 2 of the wireless transmitting circuit module A8 through wires. The wireless transmitting circuit module A10 is equipped with a 12V battery dedicated to the wireless transmitting circuit, and is installed in the remote control box together with the wireless transmitting circuit module A10. The four buttons of the wireless transmitting circuit module A10 (wireless control circuit A10) are located outside the upper end of the remote control box.The wireless receiving circuit modules A1 and A7 are each equipped with a DC-DC power supply module A16 and A17 for converting a DC 24V to a DC 5V power supply, which can convert the input DC 24V power supply into a DC 5V to supply power to the wireless receiving circuit modules A1 and A7; the input ends 1 and 2 of the two DC-DC power supply modules A16 and A17 are connected to the normally closed contact end of the relay K11, the negative pole of the battery G, and the 3 and 4 pins of the time-controlled switch A13 through wires, and the power output ends 3 and 4 pins of the two DC-DC power supply modules A16 and A17 are connected to the power input ends 1 and 3 pins of the wireless receiving circuit modules A1 and A7 through wires (the power output end 3 pin of the DC-DC power supply module A16 is separately connected to the 1 pin of the wireless receiving circuit module A1 and the positive power input end of the relay K1, and the power output ends 3 pins of the DC-DC power supply module A17 are separately connected to the 1 pin of the wireless receiving circuit module A7 and the positive power input ends of the relays K8, K12, and K7).

[0023] Figure 1 , 2As shown in 3, 4, and 5, before the present invention is used, the electric drive vehicle 101, the column 102, the semicircular arc guide groove plate 103, and the horizontal connecting rod 104 of the main vehicle body are in a split state, which is convenient for transfer and transportation. After being assembled on site, it can be put into use. After the inspection personnel control the movement of the main vehicle body 1 through the wireless control circuit 5, they no longer perform any operations. They can be on duty in the duty room, do not need to follow the main vehicle body 1, etc. to perform tunnel quality inspection, or leave the site to handle other matters. After turning on the power switch S, the 24V power supply enters the control subcircuit (the 24V DC power supply enters the wireless receiving circuit module A1 with a voltage of DC 5V under the action of the DC-DC module A16) and the power input ends of the four photoelectric switches A9, A3, A4, and A5, so that the control subcircuit and the four photoelectric switches A9, A3, A4, and A5 are in an energized working state. After turning on the power switch S1, the 24V power supply enters the power input pins 1 and 2 of the trigger subcircuit's time switch A13 (the buttons and display screen are located outside the component box 46 and the front upper end of the lower shell), and the power input pins 1 and 2 of the 48 photoelectric switches A6N and A11N. Therefore, the trigger subcircuit and the 48 photoelectric switches A6N and A11N are in the energized working state. After the time switch A13 is energized and working, under the action of its internal circuit and the output power time of the 3rd and 4th pins of the time switch A13 set by the technician, it will continuously output power for a certain period of time (for example, 60 minutes) to enter the positive power input terminal of the wireless receiving circuit module A7 ((the 24V DC power supply enters the wireless receiving circuit module A7 under the action of the DC-DC module A17. The voltage is DC 5V), the positive power input terminal of the second relay K8 and the fifth relay K12, the positive power input terminal of the short message module A12 and the control power input terminal of the third relay K9. The time when the time switch A13 outputs power is the time set by the test personnel in advance. Within the set detection time (that is, within the preset detection distance, for example, the main vehicle body moves 180 meters per hour, about 5 centimeters per second, and the power output is set to 120 minutes, then the length of the detected tunnel is 360 meters. It should be noted that a margin must be left for the detection distance before the detection to prevent the set movement time from being too long, and the main vehicle body from being unable to move forward after moving to the stop point, causing slipping on the spot and no longer moving. For example, the remaining distance is only 100 meters, then the detection length can be set to 95 meters to leave some margin, and the remaining very small tunnel quality is finally manually inspected), the present invention detects the time and distance for the structural surface flatness quality of the tunnel top and both sides.

[0024] Figure 1 , 2As shown in , 3, 4, and 5, before the detection, the detection personnel press the first and third transmitting buttons S1 and S3 of the portable wireless control circuit A10 respectively (after pressing, the top detection vehicle and the main vehicle body will move respectively, and the detection personnel can return to the room or do other things, and there is no need to detect the movement of the main vehicle body on site). Then, the wireless control circuit A10 transmits the first and third wireless closing signals; after the wireless receiving circuit module A1 receives the first wireless closing signal, its 4-pin outputs a high level, which enters the base of the NPN transistor Q1 through the voltage reduction and current limiting of the resistor R1, and the collector of the NPN transistor Q1 is turned on to output a low level to enter The positive pole of the 24V power supply of the battery G enters the positive power supply input terminal 1 of the time-controlled switch A2 through the control power input terminal of the relay K11, the normally closed contact terminal - the positive control power input terminal of the relay K1, and one of the normally open contact terminals of the relay K1. Therefore, the time-controlled switch A2 is in the energized working state (the negative power supply of the 2nd foot of the time-controlled switch A2 is obtained through the other normally open contact terminal of the relay K1 and the negative control power input terminal of the relay K1 - the negative pole of the battery G). After the time-controlled switch A2 is energized and working, its 3rd and 4th feet will cyclically output 5 seconds of power every 5 seconds to enter the power input terminals of the relay K2. Therefore, the relay K2 will be energized and energized for 5 seconds every 5 seconds. During the 5 seconds of energization, its two control power input terminals and two normally open contact terminals are closed respectively, and during the 5 seconds of power loss, its two control power input terminals and two normally closed contact terminals are closed respectively. When the relay K2 is energized and its two control power input terminals and two normally open contact terminals are closed for 5 seconds, the two poles of the 24V power supply will enter the positive and negative power input terminals of the four motor reduction mechanisms M of the top inspection vehicle 2, so that the four motor reduction mechanisms M are energized to drive the four wheels 24 to rotate counterclockwise, and then the top inspection vehicle moves from right to left along the guide groove plate 103 (the upper end of the guide wheel 23 moves along the upper end of the guide groove plate 103 to guide and limit). When the relay K2 is de-energized and no longer energized, its two control power input terminals and two normally closed contact terminals are closed for 5 seconds, the two poles of the 24V power supply will enter the negative and positive power input terminals of the four motor reduction mechanisms M of the top inspection vehicle, so that the four motor reduction mechanisms M are energized at the same time to drive the four wheels 24 to rotate clockwise, and then the top inspection vehicle 2 moves from left to right along the guide groove plate 103 (the upper end of the guide wheel 23 moves along the upper end of the guide groove plate 103 to guide and limit).In actual situations, it takes less than 5 seconds (about 4.6 seconds) for the top inspection vehicle 2 to move from left to right or from right to left to the left or right stop point of the guide groove plate. Therefore, before the inspection vehicle 3 moves to the left or right stop point, the photoelectric switches A9 and A3 on both sides of the shell 21 will approach the limit plates 105 on the outside of the left and right sides of the guide groove plate 103 respectively. When the outer front detection heads of the two photoelectric switches A9 and A3 are about 10 cm close to the upper end of the limit plate 105, their three pins will output positive power to the positive power input terminals of relays K3 and K4 respectively; therefore, before the inspection vehicle moves to the left stop point of the guide groove plate, the relay K3 is energized to close its control power input terminal and the normally closed contact terminal to open the circuit. Since one of the normally open contact terminals of the relay K2 supplies power to one pole of the four motor reduction mechanisms M through the control power input terminal and the normally closed contact terminal of the relay K3, the four motor reduction mechanisms M will lose power and stop working at this moment, and then the inspection vehicle will no longer move (it can only move to the right). Before the inspection vehicle moves to the right stop point of the guide groove plate, the relay K4 is energized to close its control power input terminal and the normally closed contact terminal to open the circuit. Since one of the normally closed contact terminals of the relay K2 is powered by the control power input terminal and the normally closed contact terminal of the relay K4 to supply power to one pole of the four motor reduction mechanisms M, the four motor reduction mechanisms M will lose power and stop working at this moment, and the inspection vehicle will no longer move (it can only move to the left). Through the above circuit action, the inspection vehicle 2 will continuously cycle along the guide groove 103 to the left and right after working, and perform quality inspection on the top of the tunnel at every 25 cm interval in the longitudinal direction until the inspection is completed. The inspection personnel press the first wireless transmission button S1 of the wireless control circuit A10 again to transmit the first wireless open circuit signal. After the wireless receiving circuit module A1 receives the first wireless open circuit signal, its 4 feet stop outputting high level, the relay K1 loses power, the time control switch A2 loses power, the relay K2 loses power, the four motor reduction mechanisms M no longer rotate, and the inspection vehicle 2 stops moving.

[0025] Figure 1 , 2As shown in Figures 3, 4, and 5, when the operator presses the third wireless transmitting button S3 of the wireless control circuit A10, the wireless control circuit A10 transmits the third wireless closing signal. After the wireless receiving circuit module A7 receives the third wireless closing signal, its 6th pin will output a high level, which enters the base of the NPN transistor Q2 through the voltage reduction and current limiting of the resistor R2. The NPN transistor Q2 conducts and the collector outputs a low level, which enters the negative power input terminal of the relay K7. Therefore, the relay K7 is energized to close its two control power input terminals and two normally open contact terminals, respectively. Closed; the positive pole of the 24V power supply of the battery G1 enters the positive and negative power supply input terminals of the four motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body through the electrical appliance K9 control power supply input terminal, the normally closed contact terminal - the relay K8 control power supply input terminal, the normally closed contact terminal - the positive control power supply input terminal of the relay K7, and one of the normally open contact terminals of the relay K7 (the negative power supply of the four motor reduction mechanisms MN is obtained through the other normally open contact terminal of the relay K7 and the negative control power supply input terminal of the relay K7 - the negative pole of the battery G1). After the 24V power supply enters the positive and negative power supply input terminals of the four motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body, the four motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body are powered on at the same time, driving the four wheels 1013 to rotate counterclockwise, and then the main vehicle body 1 drives all equipment including the top inspection vehicle 2 to move forward. Until the detection is completed, the inspector presses the third wireless transmission button S3 of the wireless control circuit A10 again to transmit the third wireless open-circuit signal. After the wireless receiving circuit module A7 receives the third wireless open-circuit signal, its 6-pin stops outputting a high level, the relay K7 loses power, and the four sets of motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body stop rotating, and the main vehicle body 1 stops moving (the present invention needs to be used when the road surface on both sides of the lower end of the tunnel is flat before use).

[0026] Figure 1 , 2As shown in , 3, 4, and 5, in the initial state of the present invention, the detection heads of the photoelectric switches A4 and A5 on the housing of the top inspection vehicle are 50 cm away from the top of the tunnel, and the detection heads of the 48 photoelectric switches A6N and A11N on both sides of the main vehicle body are 50 cm away from the two ends of the inner side of the tunnel. When the main vehicle body 1 moves forward, the top inspection vehicle 2 moves left and right along the guide groove plate 103. If the tunnel construction quality is good, when the detection head of the photoelectric switch A4 is more than 48 cm away from the top of the tunnel (for example, 48.5 cm, that is, the maximum allowable protrusion on the top of the tunnel with a certain width in the horizontal direction, a continuous length of less than 25 cm in the vertical direction, and a height of less than 2 cm downward, which does not affect the quality), the 3rd pin of the photoelectric switch A4 does not output a high level, and the inspection vehicle 2 and the main vehicle body 1 move normally. If the tunnel construction quality is poor (that is, after the tunnel is poured with the second lining structure, there are protrusions with a certain horizontal width, a maximum longitudinal continuous length greater than 25 cm, and a downward height greater than 2 cm on the top of the tunnel, which will affect the quality and aesthetics), when the detection head of the photoelectric switch A4 is less than 48 cm from the top of the tunnel (for example, 47.5 cm), after the receiving head of the photoelectric switch A4 receives the infrared light beam emitted linearly by its transmitting head, its 3-pin outputs a high level through a diode VD1 that is unidirectionally conducted into the positive power input terminal of the relay K11, and then the relay K11 is energized to close its control power input terminal and the normally closed contact terminal is open (and enters the positive power input terminal 1 pin of the wireless transmitting circuit module A8). When the main vehicle body 1 moves forward and the top inspection vehicle moves left and right along the guide groove plate 103, if the tunnel construction quality is good, the detection head of the photoelectric switch A5 is less than 52 cm away from the top of the tunnel (for example, 51.5 cm, which means that the maximum allowable concave surface on the top of the tunnel has a certain lateral width, a longitudinal continuous length of less than 25 cm, and an upward height of less than 2 cm, which does not affect the quality), the 3rd pin of the photoelectric switch A5 does not output a high level, and the inspection vehicle 2 and the main vehicle body 1 move normally. If the tunnel construction quality is poor (that is, after the tunnel is poured with the second lining structure, there is a concave surface with a certain width in the horizontal direction, a continuous length greater than 25 cm in the vertical direction, and a height greater than 2 cm on the top of the tunnel, which will affect the quality and aesthetics), when the detection head of the photoelectric switch A5 is more than 52 cm away from the top of the tunnel (for example, 52.5 cm), the 3-pin receiving head of the photoelectric switch A5 cannot receive the infrared light beam emitted in a straight line by its transmitting head, and its 3-pin output high level is unidirectionally conducted through the diode VD2 into the positive power input terminal of the relay K11, so that the relay K11 is energized to close its control power input terminal and the normally closed contact terminal is open (and enters the positive power input terminal 1 pin of the wireless transmitting circuit module A8).Since the positive power input terminal and the positive control power input terminal of relay K1 are input through the control power input terminal and the normally closed contact terminal of relay K11, when the tunnel top quality is poor and there is a depression or protrusion with a longitudinal continuous length greater than 25 cm or greater than 2 cm, the positive pole and the positive control power input terminal of relay K1 will lose power, and then the time control switch A2 will lose power, and the four motor reduction mechanisms M of the top detection vehicle will also lose power, and the detection vehicle will stay at the depression or protrusion of the poor quality part of the tunnel top. After the inspector arrives at the site, he can intuitively understand the location of the depression or protrusion of the tunnel top through the stop position of the detection vehicle. Since the positive power input terminal of the wireless transmission circuit module A8 is connected to the negative poles of diodes VD1 and VD2, and the two contacts of the second wireless transmission button S2 are pre-connected, after the tunnel top quality poor detection vehicle stops moving, the wireless transmission circuit module A8 will transmit the second wireless closing signal (the voltage of the 24V DC power supply entering the wireless transmission circuit module A8 is DC 5V under the action of the DC-DC module A14).

[0027] Figure 1 , 2As shown in Figures 3, 4 and 5, during the inspection, when the main vehicle body drives the equipment as a whole to move forward along the tunnel, if the tunnel construction quality is good, the distance between the detection heads of the photoelectric switches A6N distributed from top to bottom on both sides of the pillars 102 of the main vehicle body is more than 48 cm on both sides of the tunnel (for example, 48.5 cm, which means that the maximum vertical height of the two sides of the tunnel is within 25 cm, and the protrusions to the outside are less than 2 cm, which does not affect the quality), the three pins of the multiple photoelectric switches A6N do not output high level, and the inspection vehicle and the main vehicle body move normally. If the tunnel construction quality is poor (that is, after the tunnel secondary lining structure is poured, there are protrusions on both sides of the tunnel with a vertical height greater than 25 cm and greater than 2 cm outward, which will affect the quality), as long as the detection head of one photoelectric switch A6N is less than 48 cm away from one side of the tunnel (for example, 47.5 cm), the high level output of pin 3 of any photoelectric switch A6N will be unidirectionally conducted through diode VD3 and enter the positive power input terminal of relay K9, which will cause relay K9 to be energized to close its control power input terminal and the normally closed contact terminal to open (and enter the positive power input terminal of relay K10, relay K10 will be energized to close its control power input terminal and the normally open contact terminal). During the inspection, when the main vehicle body drives the equipment as a whole to move forward along the tunnel, if the tunnel construction quality is good, the detection heads of the photoelectric switches A11N distributed from top to bottom on both sides of the main vehicle body are less than 52 cm apart on both sides of the tunnel (for example, 51.5 cm, which means that the maximum allowable vertical height on both sides of the tunnel is within 25 cm and the inner side is less than 2 cm. Depressions do not affect the quality), and the three pins of multiple photoelectric switches A11N do not output high levels, and the inspection vehicle and the main vehicle body move normally. If the tunnel construction quality is poor (that is, after the tunnel secondary lining structure is poured, there are vertical depressions of more than 25 cm on both sides of the tunnel and more than 2 cm inward, which will affect the quality), it will affect the quality. As long as the detection head of one photoelectric switch A11N is more than 52 cm away from one side of the tunnel (for example, 52.5 cm), the high level output of pin 3 of any photoelectric switch A11N will be unidirectionally conducted through diode VD4 and enter the positive power input terminal of relay K9, which will cause relay K9 to be energized to close its control power input terminal and the normally closed contact terminal to open (and enter the positive power input terminal of relay K10, relay K10 will be energized to close its control power input terminal and the normally open contact terminal to close).Since the control power input terminal of relay K7 is input through the control power input terminal and the normally closed contact terminal of relay K9, when the quality of both sides of the tunnel is poor and there are depressions or protrusions with a vertical height greater than 25 cm and greater than 2 cm, the control power input terminal of relay K7 will lose power, and then the four motor reduction mechanisms MN of the two electric drive vehicles of the main vehicle body will also lose power, and the main vehicle body will stay at the depression or protrusion at the poor quality part of the side of the tunnel. After arriving at the site, the inspector can intuitively understand the position of the depression or protrusion on the side of the tunnel through the stop position of the main vehicle body (at the same time observe the position of the top inspection vehicle. If there is no quality defect on the top of the tunnel, then the defect is at a position on both sides of the tunnel).

[0028] Figure 1 , 2As shown in Figures 3, 4, and 5, in the present invention, when there is a quality defect on the top of the tunnel, the wireless transmitting circuit module A8 transmits a second wireless closing signal. After the wireless receiving circuit module A7 receives the second wireless closing signal, its 5th pin will output a high level, which enters the base of the NPN transistor Q3 through the voltage reduction and current limiting of the resistor R3. The NPN transistor Q3 is turned on and the collector outputs a low level, which enters the negative power input terminal of the relays K8 and K12. Therefore, the relay K8 is energized to close its control power input terminal and the normally closed contact terminal is open, and the relay K 12 is energized to close its control power input terminal and normally open contact terminal; since the 24V positive power supply of the battery G1 is controlled by the power input terminal and normally closed contact terminal of the relay K8, and then enters the positive and negative power input terminals of the four motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body through the positive control power input terminal of the relay K7 and one of the normally open contact terminals of the relay K7, at this moment, the four motor reduction mechanisms MN of the two electric drive vehicles 101 of the main vehicle body will all lose power at the same time, and then the main vehicle body will stop moving. Through the above, the main vehicle body 1 can also stop moving after a quality problem occurs on the top of the tunnel during the inspection, which is convenient for subsequent inspection personnel to find the defective position of the top of the tunnel according to the position of the inspection vehicle. In the present invention, since the inspection is carried out after the road at the bottom of the tunnel is leveled, and the four motor reduction mechanisms of the two electric drive vehicles have the same power and speed, and the main vehicle body moves at a slow speed, there will be no problem of the main vehicle body moving to the left or right during the forward movement (before the main vehicle body is assembled and the power switch is turned on, the inspection personnel adjust the distance between the two columns 102 and the two side walls of the tunnel to a suitable position). After the output time of the 3rd and 4th pins of the time-controlled switch A13 of the present invention is reached, the relays K9, K7, etc. will lose power, and the main vehicle body will no longer move forward. For tunnels of longer lengths, the present invention can be divided into multiple inspections. After the tunnel quality inspection is completed, the various components of the main vehicle body are disassembled, and all inspection work is completed after transportation. The detection vehicle of the present invention moves from the left stop point to the right stop point in 5 seconds, and the vehicle body moves 5 cm per second. In 5 seconds, the quality within the longitudinal range of 25 cm in the tunnel can actually be detected; when the detection vehicle moves to detect the quality of the top of the tunnel within a range of 25 cm, the detection from left to right or from right to left is not a straight line, and the detection can cover a relatively larger area of ​​the top of the tunnel, which can achieve a better detection effect. In the present invention, the quality of all directions of the tunnel can be carefully detected, and the quality of 180 meters of the tunnel can be detected in one hour. For example, a 900-meter tunnel only needs 5 hours to complete the detection, and no manual detection is required. The detection range is a no-dead-angle detection (full coverage is achieved at every 25 cm interval at the top of the tunnel in the longitudinal direction, and full coverage is achieved at every 25 cm interval at the side of the tunnel vertically), which can achieve a better detection effect.The embodiment is mainly to introduce the working principle and process of the present invention in detail. In practical applications, by setting more photoelectric switches A6N and A11N on both sides of the pillar, a larger tunnel side coverage detection range can be achieved. By slowing down the speed of the main vehicle body, a larger tunnel top coverage detection range can be achieved (for example, by setting 10 times the number of photoelectric switches A6N and A11N, full coverage of the tunnel side every 2.5 cm vertical interval can be achieved. By lowering the speed of the main vehicle body by 5 times, full coverage of the tunnel top every 5 cm vertical interval can be achieved, so that the detection range is larger). In the present invention, whether there is a quality problem on the top of the tunnel, the wireless transmitting circuit module A8 sends out the second wireless closing signal, the main vehicle stops moving and the relay K12 is energized and attracted, or there is a quality problem on the side of the tunnel, the main vehicle stops moving and the relay K10 is energized and attracted, the negative electrode of the 24V power supply will enter the 2 and 3 pins of the SMS module A12, so the SMS module A12 is powered and works, and one of the signal input terminals 3 pins inputs a low-level trigger signal, then the SMS module will send out the pre-stored SMS, and the mobile phone of the inspector who establishes a connection with the SMS module A12 can receive the SMS and promptly understand the on-site situation and deal with it. In actual construction, excessively long and high intrusions (protrusions) can generally be found in the second lining structure of the tunnel casting, so the present invention is mainly used for the surface flatness detection of the structure after the second lining structure of the tunnel is cast.

[0029] Figure 1 , 2As shown in Figures 3, 4, and 5, before the present invention is used, the electric drive vehicle 101, the column 102, the semicircular arc guide groove plate 103, and the horizontal connecting plate 104 of the main vehicle body are in a split state, which is convenient for transfer and transportation. After being assembled on site, it can be put into use. After the inspection personnel control the movement of the main vehicle body 1 through the wireless control circuit 5, they no longer perform any operations. They can be on duty in the duty room, do not need to follow the main vehicle body 1, etc. to perform tunnel quality inspection, or leave the site to handle other matters. Under the action of the time-controlled switch of the side detection circuit 4, the present invention automatically detects the structural surface flatness quality of the tunnel top and both sides within the time preset by the inspection personnel (that is, within the preset distance). During the detection, the quality of the top of the tunnel can be detected horizontally through the top detection circuit 3 and the top detection vehicle 2, and the quality of the side wall of the tunnel can be detected under the action of the side detection circuit 4. In this way, whether the top and both sides of the tunnel are concave or convex can be detected at the same time, and when detecting, after the quality problem is detected, the main vehicle body movement can be stopped and the fault point can be indicated immediately, and the detection personnel can be prompted via the SMS module immediately to deal with it on site in time (and the construction personnel will be arranged to re-construct later). The present invention brings convenience to the detection personnel, improves the efficiency of the detection work, and can effectively ensure the detection quality. In the present invention, the mode of the top detection vehicle going back and forth to detect the quality of the top of the tunnel can achieve better monitoring coverage. Since both sides of the tunnel are not arc-shaped, it is not conducive to the movement of the detection vehicle to the side wall of the tunnel. Therefore, a plurality of fixed photoelectric switches are used for detection, which can also achieve good detection effects. The resistance values ​​of resistors R1, R2 and R3 are 1K; the model of NPN transistors Q1, Q2 and Q3 is 9013; the relays K1, K7, K12 and K8 are DC5V relays; the relays K2, K3, K4, K11, K9 and K10) are DC24V relays; the model of diodes VD1, VD2, VD3 and VD4 is 1N4001; the DC-DC modules A14, A16 and A17 are respectively 24V DC to 12V DC power supply module finished products (power 100W), 24V DC to 5V DC power supply module finished products (power 50W), and 24V DC to 5V DC power supply module finished products (power 50W). In the present invention, the pull-in current of relays K8 and K12 is only 50mA, and the current output by NPN transistor Q3 can fully meet the pull-in current requirement.

[0030] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
