Description
Technical Field
[0001] The present invention relates to the technical field of tunnel detection, and in particular to a radar antenna detection robot for tunnels. Background Art
[0002] Tunnel detection radar, also known as ground penetrating radar, is a device that uses electromagnetic waves for non-destructive testing. It is widely used in the detection of tunnel lining quality. In order to ensure the safety and normal use of the tunnel, it is necessary to conduct regular safety inspections on the tunnel. Tunnel detection radar is mainly used to detect key parts such as the tunnel vault, left and right arch waists, left and right side walls and tunnel bottom to ensure that all areas of the tunnel can be fully covered. The existing detection method is usually that the staff holds the ground coupling antenna of the radar equipment, attaches the ground coupling antenna to the wall and drives it to move along the tunnel direction to detect the tunnel data. This method has the following problems: There are arcs on the vault and left and right arch waists of the tunnel. The surface causes the radar antenna box (ground coupling antenna) of the equipment to be unable to accurately contact the tunnel surface, which in turn causes a cavity between the radar antenna box (ground coupling antenna) and the tunnel surface. When the radar signal passes through the air or materials such as plastic, it usually does not have much impact on the signal. However, if the radar signal passes through the air gap, the radar signal will be reflected at the interface between different media. If there is an air gap between the radar and the detection surface, an additional reflection interface will be formed between the air and the detection surface. The signal is reflected multiple times between the air gap and the detection surface, forming a multipath effect, thereby affecting the propagation and reception of the radar signal and making the radar measurement results inaccurate.

DETAILED DESCRIPTION
[0029] The technical solution of the present invention is further described below in conjunction with the accompanying drawings. The transmission coordination in the present invention does not limit the specific transmission mode, and can be gear transmission, chain transmission, or belt transmission.
[0030] The existing process of detecting tunnel safety through tunnel detection radar has the following problems: the arched top and left and right arch waists of the tunnel have curved surfaces, which make it impossible for the radar antenna box to accurately contact the tunnel surface, which in turn causes a cavity between the radar antenna box and the tunnel surface. The radar signal will be reflected multiple times in the cavity between the radar antenna box and the tunnel surface, forming a multipath effect, thereby affecting the propagation and reception of the radar signal, interfering with the radar signal, and causing inaccurate radar measurement results.
[0031] The electrical components in the present invention are all connected to the remote control terminal via radio, and the movement of the device can be controlled by the remote control terminal.

The radar detector 16 is used to detect the state of the tunnel structure. A gravity sensing module electrically connected to the two electric telescopic rods 13 is arranged in the radar detector 16. The gravity sensing module is used to sense the placement state of the device. The radar detector 16 is provided with an annular sleeve 17. The annular sleeve 17 corresponds to the upper and lower parts of the radar detector 16. One part has an arc-shaped cross-section and the other part has a square cross-section. The curvature of the arc is equal to the curvature of the tunnel. The annular sleeve 17 is limitedly matched with the second fixed shell 2. Initially, the tension spring 14 drives the radar detector 16 downward through transmission. The annular sleeve 17 on the radar detector 16 contacts the lower side surface in the second fixed shell 2, squeezes the annular sleeve 17, and limits the sliding of the annular sleeve 17. The second fixed shell 2 is rotatably connected with four friction wheels 18 distributed in a rectangular shape. The friction wheel 18 is located above the annular sleeve 17. The friction wheel 18 is matched with the first transmission belt 11 for transmission, and the friction wheel 18 is matched with the annular sleeve 17 for transmission.
[0033] like Figure 3 and Figure 7 As shown, the power mechanism includes two groups of two electric wheels 21 symmetrically distributed on the left and right. The two electric wheels 21 symmetrically distributed on the left and right are both arranged in adjacent first fixed shells 1. The two electric wheels 21 symmetrically distributed on the left and right are commonly sleeved with a transmission belt 22, and the transmission belt 22 is used to drive the device to move. The two transmission belts 22 are respectively fixed to the front and rear sides of the first transmission belt 11, and are used to drive the transmission belt 22 to move. An auxiliary mechanism is commonly arranged in the symmetrically distributed first fixed shell 1, and the auxiliary mechanism is used to assist the transmission belt 22 to fit the wall.
[0034] like Figure 7-10As shown, the auxiliary mechanism includes two connecting pipes 3 symmetrically distributed front and back, the two connecting pipes 3 are respectively fixed to the adjacent first fixed shells 1, the two connecting pipes 3 symmetrically distributed front and back are commonly connected to a suction member 31, the suction member 31 is a vacuum pump, and the suction member 31 is used to extract air. A third fixed shell 32 is fixedly connected to the interior of the first fixed shell 1, and the connecting pipe 3 passes through the adjacent first fixed shell 1 and is connected to the adjacent third fixed shell 32. After the suction member 31 is started, the suction member 31 extracts the air in the two third fixed shells 32 through the two connecting pipes 3, and the third fixed shell 32 A second transmission belt 33 is sleeved, a notch is opened on the lower side of the third fixed shell 32, and the second transmission belt 33 is fixedly connected with equidistantly distributed fixed tubes 34, which connect the two sides of the second transmission belt 33, and the fixed tubes 34 are sealed with the adjacent third fixed shell 32. The first fixed shell 1 is fixedly connected with four rectangularly distributed transmission shafts 35, and the four rectangularly distributed transmission shafts 35 are located at the four corners of the adjacent second transmission belt 33. The transmission shaft 35 is in transmission cooperation with the adjacent electric wheel 21, and the transmission shaft 35 is in transmission cooperation with the adjacent second transmission belt 33. During rotation, the adjacent second transmission belt 33 is driven to rotate on the adjacent third fixed shell 32 through the adjacent transmission shaft 35. The transmission belt 22 is provided with uniformly distributed adsorption holes 36. The spacing between two adjacent adsorption holes 36 is equal to the spacing between two adjacent fixed tubes 34. The fixed tube 34 is slidably matched with the adjacent adsorption holes 36. When the fixed tube 34 rotates following the adjacent second transmission belt 33, the fixed tube 34 gradually enters the adjacent adsorption hole 36. The transmission belt 22 is fixedly connected with staggered isolation strips 37. The staggered isolation strips 37 separate the adjacent adsorption holes. 36 isolation, the staggered isolation strips 37 form a number of square frames on the adjacent transmission belts 22, the adsorption holes 36 are located in the adjacent square frames, the hardness of the transmission belt 22 is greater than the hardness of the isolation strips 37, so that the isolation strips 37 are more easily squeezed and deformed, and an air outlet is arranged on the right side of the air suction member 31, the air outlet of the air suction member 31 is fixedly connected and connected with a duct 4, the duct 4 is located on the right side of the air suction member 31, the duct 4 is fixedly connected and connected with an air outlet plate 41, the air outlet plate 41 is provided with evenly distributed air outlet holes, and the wind blown out from the air outlet plate 41 is used to clean the dust on the path when in use.
[0035] like Figure 4 and Figure 7As shown, an electric two-way telescopic rod 5 is fixedly connected to the lower side of the suction member 31, and the two telescopic ends of the electric two-way telescopic rod 5 are respectively fixedly connected to the adjacent connecting pipe 3, the connecting pipe 3 between the electric two-way telescopic rod 5 and the suction member 31 is a hose, and the rest of the connecting pipe 3 is a hard tube, and the suction member 31 is slidably connected to a fixing member 51 through a cylindrical, and two first springs 52 respectively sleeved on two cylinders are fixedly connected between the fixing member 51 and the suction member 31, and the first spring 52 is used to squeeze the fixing member 51, and the hinged positions of the second fixed shell 2 and the two symmetrically distributed first fixed shells 1 are both provided with inclined surfaces, and the distance between the two inclined surfaces gradually decreases from bottom to top, and the fixing member 51 consists of a square plate and four rotating wheels rotatably connected to the square plate, the fixing member 51 is extruded and matched with the first transmission belt 11, and the four rotating wheels correspond to the adjacent friction wheels 18 up and down.
[0036] When using the device to perform radar detection on the tunnel ground, the staff first puts the device on the tunnel ground, and the device fits with the ground. Then the staff starts the four electric wheels 21 and the radar detector 16 through the remote control terminal. The four electric wheels 21 drive the two transmission belts 22 to rotate, and the two transmission belts 22 drive the first transmission belt 11 to rotate. The rotation of the transmission belts 22 and the first transmission belt 11 causes the device to move to the right. While the device moves as a whole, the radar detector 16 continuously detects the tunnel, thereby obtaining tunnel data.
[0037] When the radar detector 16 moves to the right along the tunnel, the six tension springs 14 drive the radar detector 16 to move downward through the two transmission plates 15, so that the annular sleeve 17 is tightly fitted with the lower side of the first transmission belt 11, and the lower side of the first transmission belt 11 is tightly fitted with the ground. During the movement of the device, the first transmission belt 11 and the annular sleeve 17 slide against each other, and the signal emitted by the radar detector 16 passes through the annular sleeve 17 and the first transmission belt 11 directly to the ground, avoiding the gap between the first transmission belt 11 and the ground, preventing the multipath effect, and improving the detection accuracy.
[0038] When the top of the tunnel is detected by this device (still Figure 1The direction in the figure shall prevail), the staff lifts the device to assist in moving, the gravity sensing module detects that the device is flipped or tilted, the gravity sensing module transmits an electrical signal to the electric telescopic rod 13, the telescopic end of the electric telescopic rod 13 extends upward, the telescopic ends of the two electric telescopic rods 13 drive the radar detector 16 to move upward through the two transmission plates 15, the radar detector 16 drives the annular sleeve 17 to move upward, the annular sleeve 17 is separated from the first transmission belt 11 and the second fixed shell 2, during the upward movement of the annular sleeve 17, the annular sleeve 17 contacts with the four friction wheels 18 and then stops, the friction wheel 18 is always in contact with the first transmission belt 11, at this time, during the rotation of the first transmission belt 11, the first transmission belt 11 is driven by the four friction wheels 18 The movable annular sleeve 17 rotates, and when the upper arc surface of the annular sleeve 17 rotates to the lower side, the telescopic end of the electric telescopic rod 13 begins to shrink, and the radar detector 16 moves downward through the drive of the six tension springs 14 until the radar detector 16 stops after being reset. At this time, the telescopic end of the electric telescopic rod 13 is separated from the transmission plate 15, and the annular sleeve 17 is fitted with the first transmission belt 11. The arc surface on the lower side of the annular sleeve 17 squeezes the lower side of the first transmission belt 11, so that the lower side of the first transmission belt 11 is an arc surface, so that the first transmission belt 11 is fitted with the tunnel top (the tunnel top is an arc surface), so that the device can intelligently adjust the shape of the first transmission belt 11 according to the measured position, and the first transmission belt 11 is always fitted with the tunnel to prevent the multipath effect and improve the measurement accuracy.
[0039] In the above process, the two first springs 52 squeeze the fixing member 51, so that the four rollers on the fixing member 51 and the four friction wheels 18 squeeze the first transmission belt 11 to prevent the first transmission belt 11 from being separated from the friction wheels 18, thereby ensuring stable transmission of the friction wheels 18.
[0040] In the process of using the device to move to the right, the staff starts the suction piece 31 through the remote control terminal. The suction piece 31 absorbs the air in the two third fixed shells 32 through the two connecting pipes 3, so that there is a negative pressure in the third fixed shell 32. In the process of rotating the electric wheel 21, the electric wheel 21 drives the adjacent second transmission belt 33 to rotate through the adjacent transmission shaft 35. The speed and direction of rotation of the second transmission belt 33 are the same as the speed and direction of rotation of the adjacent transmission belt 22. The second transmission belt 33 drives the fixed tube 34 thereon to rotate during the rotation. Taking one fixed tube 34 as an example, the fixed tube 34 follows the second transmission belt 33 in the process of rotating. As the clockwise direction rotates, the fixed tube 34 gradually enters into the adjacent adsorption hole 36 during the process of moving from the right side of the third fixed shell 32 to the lower right side. When the fixed tube 34 starts to move to the left from the lower right side, it completely enters into the adjacent adsorption hole 36. Then the fixed tube 34 continues to move to the left. The fixed tube 34 gradually disengages from the third fixed shell 32 and communicates with the inside thereof. At this time, the third fixed shell 32 is communicated with the outside through the fixed tube 34. The wall is adsorbed by negative pressure, so that the lower side of the transmission belt 22 fits the wall. When the fixed tube 34 moves to contact with the third fixed shell 32, the third fixed shell 32 gradually blocks the fixed tube 34. Then the fixed tube 34 continues to move and disengages from the adjacent adsorption hole 36. Then the cycle continues.
[0041] When the transmission belt 22 is in contact with the wall, the isolation strip 37 on the transmission belt 22 is also in contact with the wall. The isolation strip 37 is deformed after being squeezed by the wall, so that the wall, the isolation strip 37 and the transmission belt 22 form a sealed space, thereby improving the stability of the adsorption hole 36 during the adsorption process on the wall.
[0042] After starting the air suction member 31, the air discharged from the exhaust port of the air suction member 31 enters the air outlet plate 41 through the duct 4. The air outlet plate 41 cleans the wall in the moving direction of the device through the wind, reducing dust on the wall and further improving the stability of the adsorption hole 36 during the wall adsorption process.
[0043] When detecting a curved position in the tunnel (such as the top of the tunnel), the staff starts the electric two-way telescopic rod 5, and the two telescopic ends of the electric two-way telescopic rod 5 drive the two connecting pipes 3 to approach each other, and the connecting pipe 3 drives the adjacent first fixed shell 1 to rotate around the rotating shaft between the second fixed shell 2, and the first fixed shell 1 gradually fits with the inclined surface on the second fixed shell 2, and the front and rear first fixed shells 1 and the transmission belts 22 thereon rotate upward together, so that the transmission belts 22 can better fit the wall surface and improve the adsorption force on the wall surface, and then the electric two-way telescopic rod 5 is closed.
[0044] After use, the first fixed shell 1 is reset, and the radar detector 16, the air suction member 31 and the electric wheel 21 are turned off.
[0045] Embodiment 2: Based on embodiment 1, Figure 1 and Fig.11 As shown, it also includes a supporting mechanism, which is used to support the suction member 31. The supporting mechanism is arranged on the outside of two symmetrically distributed first fixed shells 1. The supporting mechanism includes a fixed frame 6, which is arranged at the symmetrically distributed first fixed shells 1. The fixed frame 6 is connected to the external mobile vehicle. The lower side of the fixed frame 6 is slidably connected with a sliding frame 61, and the suction member 31 is located in the sliding frame 61. The fixed frame 6 is fixed with an elastic telescopic rod 62, and the telescopic end of the elastic telescopic rod 62 is fixed with a supporting plate 63. The supporting plate 63 contacts and cooperates with the suction member 31. When in use, the suction member 31 is supported by the supporting plate 63 so that the device fits the wall. The sliding frame 61 is slidably connected with four supporting rods 64 distributed in a rectangular shape. The supporting rod 64 is ball-jointed with the adjacent first fixed shells 1. Two second springs 65 respectively mounted on the two supporting rods 64 are fixed between the first fixed shell 1 and the sliding frame 61. The second spring 65 is used to support the adjacent first fixed shells 1.
[0046] In the process of using the present device, the fixed frame 6 is first installed on a movable robotic arm, the robotic arm is connected to the remote control terminal, and then the robotic arm is controlled to move forward through the remote control terminal, and the robotic arm drives the fixed frame 6, the fixed frame 6 drives the sliding frame 61, and the sliding frame 61 drives the two first fixed shells 1 through four support rods 64 and four second springs 65, thereby driving all nearby parts, and the first transmission belt 11 is attached to the wall through the robotic arm.
[0047] When the first transmission belt 11 is in contact with the vertical wall, the sliding frame 61 supports the up and down force of the first fixed shell 1 through the two second springs 65, and squeezes the support plate 63 through the elastic telescopic rod 62, and the support plate 63 squeezes the suction piece 31 to provide a force to fit the wall. During detection, the mechanical arm and the first transmission belt 11 are moved synchronously through the remote control terminal. After the suction piece 31 is started, the suction piece 31 provides suction for the device. When the ground is uneven or there are impurities, even if the mechanical arm shakes up and down in a small range, the shaking force acts on the second spring 65, and the up and down shaking force will not directly act on the first fixed shell 1. Under the suction provided by the second spring 65 and the suction piece 31, the device can still move in a straight line even if the ground is uneven, thereby improving the stability during detection.
[0048] When the first transmission belt 11 is attached to the top, under the joint action of the elastic telescopic rod 62 and the air suction member 31, even if the mechanical arm shakes in the up and down directions, it will not affect the moving direction of the radar detector 16, thereby improving the stability during detection.
