Description

Technical Field

[0001] The present invention belongs to the technical field of road exploration layers, and particularly relates to a road construction exploration layer device and an exploration layer method. Background Technique

[0002] Road construction exploration layer is a key link in highway construction, mainly involving detecting the actual situation of subgrade construction to ensure construction quality and safety. Traditional road construction exploration layer methods mainly rely on means such as drilling and sampling. In recent years, with the rapid development of engineering geophysical exploration technologies, especially the application of non-destructive testing technologies such as ground penetrating radar, geological radar detection method, and acoustic wave detection method, more efficient and accurate solutions have been provided for road construction exploration layers. After retrieval, the publication number CN116538970A discloses a ground penetrating radar detection and acceptance method for the thickness of road structural layers, including the following steps: calibrating the dielectric constant of the road structural layer at each measuring point; fitting the dielectric constant of each measuring point with a normal distribution curve; testing the two-way travel time of electromagnetic waves at the thickness acceptance measuring points; calculating the probability distribution interval of the two-way travel time in the thickness acceptance qualified interval; calculating the acceptance qualified probability of the measuring points and judging the thickness qualified situation.

[0003] In the prior art, since the radar detector mostly needs to move close to or fit the ground for detection during use, it is necessary to clean the stones on the device moving road before exploration layer. If not cleaned, it is easy to damage the radar detector when the device moves; secondly, most of the existing road exploration layer devices only have one exploration layer method to detect the road. Therefore, when a failure occurs, exploration layer detection cannot be carried out, which is not conducive to improving the working efficiency of road exploration layers.

[0016] A method for detecting layers in road construction, characterized in that the method is as follows:

[0017] Step 1: Place the radar detector for road layer detection on one side of the moving mechanism. Push the rotating rod to rotate around the main shaft through the electric push rod installed between the bracket and the rotating rod. Utilize the principle of the lever to drive the obstacle-clearing inclined guide plate to flip during the rotation of the rotating rod, so that the lowest point of the vertical plane of the obstacle-clearing inclined guide plate is higher than the highest point of the vertical plane of the vehicle frame. After the structural deformation is completed, lower the height of the support plate by rotating the screw rod to complete the preparatory work before assembling the device;

[0018] Step 2: Push the lifting mechanism and the moving mechanism to move to one side through the push handle. After the radar detector enters the interior of the vehicle frame, use the baffle to block and limit the position of the radar detector inside the vehicle frame. Raise the height of the support plate by rotating the screw rod, and use the support plate to lift the radar detector from the ground so that the bottom of the radar detector is kept at a certain height from the ground. Manually adjust the position of the sliding rod on the positioning bolt, and after adjustment, rotate the positioning bolt to cooperate with the support plate to clamp and limit the radar detector to complete the assembly of the moving mechanism and the radar detector. After the assembly is completed, restart the electric push rod, and the obstacle-clearing inclined guide plate resets under the drive of the rotating rod, so that the lowest point of the adjusted obstacle-clearing inclined guide plate is lower than the lowest point of the bottom of the radar detector;

[0019] Step 3: After connecting the console to an external power source, use the GPS locator to detect the position of the device. Use the radar detector to detect the distribution of underground media with ultra-high frequency electromagnetic waves. Push the device to move through the push handle to achieve continuous detection. The detected results are displayed to the user through the console. During the movement of the device, use the obstacle-clearing inclined guide plate to push the stones in the moving direction of the device to avoid damage to the radar detector caused by the stones;

[0020] Step 4: Start the motor to drive the core barrel to rotate. Start the motor, and the motor moves the mounting plate up and down through the lead screw. During the adjustment process, drive the drilling mechanism to move up and down. When the mounting plate moves downward, drive the slider to move downward at the same time. The mudguard that loses the limit of the slider automatically moves downward to contact the ground under the guidance of its own weight, realizing the separation between the radar detector and the drilling mechanism. After the drilling mechanism is inserted into the ground, take out the soil layer from the ground to achieve drilling detection. During the upward movement of the drilling mechanism, use the slider to drive the mudguard to move upward so that the mudguard is separated from the ground for easy movement adjustment.

[0021] The technical effects and advantages of the present invention:

[0022] 1. The present invention installs an adjustable obstacle clearing mechanism on one side of the moving mechanism. During use, through the mutual cooperation of the rotating rod, the main shaft, the electric push rod, and the bracket, the obstacle clearing inclined guide plate can be flipped and adjusted according to requirements. After the structural deformation is completed, the assembly of the radar detector can be realized. After the assembly is completed, the electric push rod is restarted, and the obstacle clearing inclined guide plate is reset under the drive of the rotating rod, so that the lowest point of the adjusted obstacle clearing inclined guide plate is lower than the lowest point of the bottom of the radar detector. When moving, the obstacle clearing inclined guide plate can guide and divert the stones outward, realizing the shielding protection of the radar detector;

[0023] 2. The present invention has a drilling mechanism installed inside the lifting mechanism. During the operation of the drilling mechanism, the core barrel rotates rapidly, and the mounting plate moves up and down under the drive of the lead screw, thereby realizing the drilling and sampling of the road. After taking out the sample inside the core barrel, the exploration layer detection is realized. The radar detector can emit high-frequency electromagnetic waves, and the geological target is detected by studying the time, speed, and dynamic characteristics of the wave propagation in the ground, improving the working efficiency of the road exploration layer;

[0024] 3. The present invention has a mudguard slidably installed inside the limiting groove and a slider inserted into the sliding groove. When the drilling mechanism moves downward, it simultaneously drives the slider to move downward inside the sliding groove. The mudguard that loses the support of the slider automatically falls and contacts the ground under the action of its own gravity, isolating the radar detector from the drilling mechanism and preventing the mud splashed during the processing of the drilling mechanism from splashing onto the radar detector, keeping the radar detector clean.

After the device is connected to an external power supply, the GPS locator 4 is used to locate the position of the device. While the device is moving, the radar detector 3 performs exploration layer detection on the road. The obstacle clearing mechanism 5 clears the stones in the moving direction to both sides, making the movement of the moving mechanism 1 smoother and increasing the protection effect on the radar detector 3. The lifting mechanism 6 is used to adjust the height of the drilling mechanism 9. During the operation of the drilling mechanism 9, the road is drilled and sampled to facilitate the detection of the sampled soil layer.

Through the mutual cooperation of the rotating rod 502, the main shaft 503, the electric push rod 504 and the bracket 505, the obstacle clearing inclined guide plate 501 can be flipped and adjusted according to needs, so as to realize the shielding and protection of the radar detector 3;

[0040] The lifting mechanism 6 includes a lifting frame 601. The lifting frame 601 is connected to the other side of the moving mechanism 1. At both ends inside the lifting frame 601, there are screw rods 602 rotatably installed. At both ends of the top of the lifting frame 601, there are motors 603 installed. The output end of the motor 603 is fixedly connected to the top of the screw rod 602. Among them, the output end of the motor 603 is rotatably connected to the lifting frame 601. Specifically, during the operation of the motor 603, it drives the screw rod 602 to rotate synchronously, and by controlling the rotation direction of the motor 603, it realizes driving the drilling mechanism 9 to move up and down.

[0041] As a specific implementation manner of the present invention, on the other side between the bracket 505 and the lifting frame 601, there are several connecting rods 506 fixedly connected. At the top of the connecting rod 506, there is a flash lamp 507 installed. Specifically, the connecting rod 506 can be used to increase the stability between the structures of the moving mechanism 1 and the lifting mechanism 6. After the flash lamp 507 is powered on, it can emit light to the surrounding, making the device more eye-catching when in use.

[0042] As a specific implementation manner of the present invention, the moving mechanism 1 includes a vehicle frame 101. At both ends inside the vehicle frame 101, there are screw rods 104 rotatably installed. The bottom of the screw rod 104 is rotatably connected to a support plate 103. The radar detector 3 is mounted between the screw rods 104. And at one end of the screw rod 104 close to the radar detector 3, there is a rubber pad 106 wrapped. On the other side of the support plate 103, there is a baffle 107 installed. At both ends of the vehicle frame 101 and the lifting frame 601, there are wheels rotatably installed.

[0044] By rotating and adjusting the screw rod 104 rotatably installed inside the vehicle frame 101, the position of the support plate 103 inside the vehicle frame 101 can be adjusted up and down. Using the rubber pad 106 installed on the support plate 103, the support plate 103 can be wrapped and protected to avoid damage to the outer wall of the radar detector 3 when the support plate 103 is adjusted. Through the baffle 107, the position of the radar detector 3 on the support plate 103 can be limited during use. After rotating the screw rod 104 in the reverse direction, the screw rod 104 drives the support plate 103 to move upward, so that the bottom of the radar detector 3 is separated from the ground, realizing the suspension installation. During the movement of the support plate 103, it simultaneously drives the guide rods 105 to move up and down inside the vehicle frame 101, making the movement of the support plate 103 more stable. The limit groove 102 can be used to guide the movement track of the fender 10.

[0045] As a specific embodiment of the present invention, the positioning mechanism 2 includes a positioning rod 201, a convex block 202, a sliding rod 203 and a positioning bolt 204.

During use, the position of the sliding rod 203 on the convex blocks 202 can be adjusted horizontally, changing the position of the positioning bolt 204 on the radar detector 3. After the adjustment is completed, by rotating the positioning bolt 204, during the rotation of the positioning bolt 204, the rubber platform squeezes the top of the radar detector 3, and in cooperation with the support plate 103, the radar detector 3 is clamped and limited, making the radar detector 3 more stable.

[0047] As a specific embodiment of the present invention, the drilling mechanism 9 includes a mounting plate 901, a motor 902 and a core barrel 903.

[0048] The drilling mechanism 9 is assembled around the lead screw 602 through the screw holes provided on the mounting plate 901. The position of the drilling mechanism 9 is adjusted by the cooperation of the external thread on the lead screw 602 and the screw holes. After starting the motor 902, the output end of the motor 902 can drive the core barrel 903 to rotate simultaneously.

[0051] By pushing the armrest 7, it is convenient for the user to push the moving mechanism 1 and the lifting mechanism 6 during use. The wheels assembled on the moving mechanism 1 and the lifting mechanism 6 are used to reduce the resistance encountered during the movement of the moving mechanism 1 and the lifting mechanism 6. After the control console 8 is connected to an external power source, it can transmit external power to the radar detector 3, the GPS locator 4, the electric push rod 504, the flash lamp 507, the motor 603, and the electric motor 902 respectively, so that the user can control the devices that need to operate on the device. The data detected by the radar detector 3 and the GPS locator 4 during use can be displayed through the control console 8 for easy data reading.

[0052] A method for detecting road layers in road construction, characterized in that the method is as follows:

[0053] Step 1: Place the radar detector 3 for road layer detection on one side of the moving mechanism 1. Push the rotating rod 502 to rotate and adjust around the main shaft 503 by the electric push rod 504 installed between the bracket 505 and the rotating rod 502. Utilize the principle of the lever to drive the obstacle-clearing inclined guide plate 501 to flip during the rotation of the rotating rod 502, so that the lowest point of the vertical plane of the obstacle-clearing inclined guide plate 501 is higher than the highest point of the vertical plane of the vehicle frame 101. After the structural deformation is completed, lower the height of the support plate 103 by rotating the screw rod 104 to complete the preparatory work before assembling the device.

[0054] Step 2: Push the lifting mechanism 6 and the moving mechanism 1 to move to one side by pushing the armrest 7. After the radar detector 3 enters the interior of the vehicle frame 101, use the baffle 107 to block and limit the position of the radar detector 3 inside the vehicle frame 101. Raise the height of the support plate 103 by rotating the screw rod 104, and use the support plate 103 to lift the radar detector 3 from the ground so that the bottom of the radar detector 3 is kept at a certain height from the ground. Manually adjust the position of the sliding rod 203 on the positioning bolt 204, and after adjustment, rotate the positioning bolt 204 to cooperate with the support plate 103 to clamp and limit the radar detector 3 to complete the assembly of the moving mechanism 1 and the radar detector 3. After the assembly is completed, restart the electric push rod 504, and the obstacle-clearing inclined guide plate 501 resets under the drive of the rotating rod 502, so that the lowest point of the adjusted obstacle-clearing inclined guide plate 501 is lower than the lowest point of the bottom of the radar detector 3.

[0055] Step 3: After connecting the control console 8 to an external power source, use the GPS locator 4 to detect the location of the device. Use the radar detector 3 to detect the distribution of underground media by using ultra-high frequency electromagnetic waves. Realize continuous detection by pushing the device to move through the armrest 7. The detection results are displayed to the user through the control console 8. During the movement of the device, use the obstacle-clearing inclined guide plate 501 to push the stones in the moving direction of the device to avoid damage to the radar detector 3 caused by the stones.

[0056] Step 4: Start the motor 902 to drive the core barrel 903 to rotate. Start the motor 603. The motor 603 adjusts the up-and-down movement of the mounting plate 901 through the lead screw 602. During the adjustment process, the drilling mechanism 9 is driven to move up and down. When the mounting plate 901 moves downward, the slider 12 is driven to move downward at the same time. The mudguard 10 that loses the limit of the slider 12 automatically moves downward under the guidance of its own weight and contacts the ground, realizing the separation between the radar detector 3 and the drilling mechanism 9. After the drilling mechanism 9 is inserted into the ground, the soil layer is taken out from the ground, thus realizing the drilling detection. During the upward movement of the drilling mechanism 9, the slider 12 is used to drive the mudguard 10 to move upward, so that the mudguard 10 is separated from the ground for easy movement adjustment.

5. A method for exploring layers in road construction, based on a road construction layer exploration device according to any one of claims 1-3, characterized in that, The method is as follows: Step 1: Place the radar detector (3) for road layer detection on one side of the moving mechanism (1). Push the rotating rod (502) to rotate and adjust around the main shaft (503) through the electric push rod (504) installed between the bracket (505) and the rotating rod (502). Utilize the principle of the lever to drive the obstacle-clearing inclined guide plate (501) to flip during the rotation of the rotating rod (502), so that the lowest point of the vertical plane of the obstacle-clearing inclined guide plate (501) is higher than the highest point of the vertical plane of the vehicle frame (101). After the structural deformation is completed, rotate the screw rod (104) to lower the height of the support plate (103), so that the device completes the preparatory work before assembly. Step 2: Push the lifting mechanism (6) and the moving mechanism (1) to move to one side by pushing the handrail (7), so that the radar detector (3) enters the inside of the vehicle frame (101). Then use the baffle (107) to block and limit the position of the radar detector (3) inside the vehicle frame (101). Lift the height of the support plate (103) by rotating the screw rod (104), and use the support plate (103) to lift the radar detector (3) from the ground, so that the bottom of the radar detector (3) keeps a certain height from the ground. Manually adjust the position of the slide rod (203) on the positioning bolt (204), and after adjustment, rotate the positioning bolt (204) to cooperate with the support plate (103) to clamp and limit the radar detector (3), completing the assembly of the moving mechanism (1) and the radar detector (3). After the assembly is completed, restart the electric push rod (504), and the obstacle-clearing inclined guide plate (501) resets under the drive of the rotating rod (502), so that the lowest point of the adjusted obstacle-clearing inclined guide plate (501) is lower than the lowest point of the bottom of the radar detector (3). Step 3: After connecting the console (8) to an external power supply, use the GPS locator (4) to detect the location of the device. The radar detector (3) uses ultra-high frequency electromagnetic waves to detect the underground medium distribution. Push the device to move through the handrail (7) to achieve continuous detection. The detected results are displayed to the user through the console (8). During the movement of the device, use the obstacle-clearing inclined guide plate (501) to push the gravel in the moving direction of the device to avoid damage to the radar detector (3) caused by the gravel. Step 4: Start the motor (902) to drive the core barrel (903) to rotate. Start the motor (603), and the motor (603) moves the mounting plate (901) up and down through the lead screw (602). During the adjustment process, drive the drilling mechanism (9) to move up and down. When the mounting plate (901) moves downward, drive the slider (12) to move downward at the same time. The mudguard (10) that loses the limit of the slider (12) automatically moves downward to contact the ground under the guidance of its own weight, realizing the separation between the radar detector (3) and the drilling mechanism (9). After the drilling mechanism (9) is inserted into the ground, take out the soil layer from the ground, thus realizing the drilling detection. When the drilling mechanism (9) moves upward, use the slider (12) to drive the mudguard (10) to move upward, so that the mudguard (10) is separated from the ground for easy movement adjustment.
