Description

Technical Field

[0001] This application relates to the field of non-destructive testing, and in particular to a non-destructive testing device for reinforced concrete structures. Background Technology

[0002] Non-destructive testing (NDT) refers to a testing method that inspects the surface and internal quality of a component without damaging the workpiece or raw material.

[0003] In related technologies, when conducting flaw detection on connecting beams between buildings or terraces at the edge of buildings, operators need to move a handheld ultrasonic flaw detector to the corresponding position and observe the parameters on the monitor in order to inspect the interior of the connecting beams or terraces.

[0004] Regarding the aforementioned technologies, the inventors have found that when operators conduct flaw detection on relatively dangerous areas such as connecting beams between buildings or terraces at the edges of buildings, they need to use specific protective tools for protection before operating. This poses a certain degree of danger to the operators, and constantly observing the detection parameters can easily distract them, leading to errors in the final detection results. Therefore, improvements are needed. Summary of the Invention

[0005] To address the problems encountered by operators when performing flaw detection on the area to be inspected, this application provides a non-destructive testing device for reinforced concrete structures.

[0006] This application provides a non-destructive testing device for reinforced concrete structures, which adopts the following technical solution:

[0007] A non-destructive testing device for reinforced concrete structures includes a mobile vehicle body, on which a detection component and a display component are provided, arranged side by side. A drive cavity is formed in the mobile vehicle body, and a drive component is provided within the drive cavity. The drive component is connected to the display component and controls the rotation of the display component. A starting component is provided in the drive cavity, and a control component is provided on the display component. The starting component is connected to the detection component, and the drive component drives the control component to rotate until it is connected to the starting component.

[0008] The detection assembly includes a first link and a second link. The first link is rotatably connected to the mobile vehicle body, and the second link is rotatably connected to the end of the first link away from the mobile vehicle body. The end of the second link away from the first link is provided with a detection head and a spray head for spraying coupling agent. The first link and the second link are connected by a connecting assembly.

[0009] By adopting the above technical solution, when flaw detection is required on dangerous locations such as connecting beams between buildings or terraces at the edges of buildings, the operator moves the mobile vehicle to a relatively flat platform, then activates the drive assembly. The drive assembly drives the display assembly to rotate. When the display assembly rotates to the designated position, the control assembly connects with the starting assembly. At this time, the drive assembly drives the control assembly to start, and the control assembly drives the starting assembly to start. The starting assembly starts and drives the first link to rotate away from the mobile vehicle body. Then, under the action of the connecting assembly, the first link drives the second link to rotate away from the first link, thus... The first and second links unfold, and the second link then moves the detection head and spray head toward the position to be inspected. When the detection head and spray head come into contact with the position to be inspected, the moving vehicle moves, the spray head sprays out the coupling agent, and the detection head performs inspection at the position to be inspected. At the same time, the display component displays the detection result of the detection head. At this time, the display component is tilted to facilitate the operator to observe the measurement value of the detection head more intuitively. Meanwhile, under the action of the first link, the second link, and the moving vehicle, the number of manual inspection steps for the operator is reduced, and the safety factor is improved when the operator performs flaw detection on high-risk positions.

[0010] Preferably, the connecting assembly includes a connector and a control component. One end of the connector is connected to the mobile vehicle body and the other end is connected to the first connecting rod. One end of the control component is connected to the connector and the other end is connected to the second connecting rod.

[0011] The connector includes a first connecting wheel and a second connecting wheel. The first connecting wheel is mounted on the mobile vehicle body, and the second connecting wheel is rotatably connected to a first connecting rod. A first connecting belt is wound around the first and second connecting wheels.

[0012] The control component includes a first control wheel, a second control wheel, and a moving block. The first control wheel is coaxially mounted on the second connecting wheel. A moving groove is formed on the second connecting rod along its length. A guide is provided in the moving groove along the direction of the second connecting rod. The moving block is slidably connected to the guide. A connecting column is rotatably connected to the moving block. The connecting column is connected to the guide. The second control wheel is coaxially mounted at the end of the connecting column away from the moving block. A second connecting belt is wound around the first and second control wheels.

[0013] By adopting the above technical solution, when the first connecting rod rotates, the first connecting belt rotates along with the first connecting rod. Under the action of the constant length of the first connecting belt, the first connecting rod rotates around the axis of the first connecting wheel. At this time, the first connecting belt rotates and drives the second connecting wheel to rotate. The rotation of the second connecting wheel drives the first control wheel to rotate. The rotation of the first control wheel drives the second connecting belt to rotate. The rotation of the second connecting belt drives the second control wheel to rotate. The rotation of the second control wheel drives the connecting column to rotate. Under the cooperation of the connecting column and the guide, the moving block moves along the guide. The movement of the moving block causes the second connecting rod to rotate in a direction away from the first connecting rod, so that the detection head and the spray head move towards the area to be detected. This realizes that the second connecting rod rotates at the same time as the first connecting rod, which improves the efficiency of moving the detection head and the spray head to the area to be detected. At the same time, it reduces the error that exists when the operator performs manual inspection and reduces the possibility of danger to the operator.

[0014] Preferably, the guide member includes a guide rack, a reversing gear, and a moving gear. The guide rack is disposed in a moving groove along the length direction of the second connecting rod. The moving block is slidably connected to the guide rack. A clearance groove is formed on the side of the moving block near the guide rack. The connecting post extends into the clearance groove and is rotatably connected to the inner wall of the clearance groove. The reversing gear is coaxially disposed on one end of the connecting post located in the clearance groove. The moving gear is rotatably connected to the inner wall of the clearance groove. The reversing gear meshes with the moving gear. The side of the moving gear away from the reversing gear meshes with the guide rack.

[0015] By adopting the above technical solution, the second control wheel drives the connecting column to rotate, the connecting column drives the reversing gear to rotate, the reversing gear drives the moving gear to rotate, and the moving gear rotates and drives the moving block to move along the guide rack. Under the action of the guide rack, the moving gear and the reversing gear, the stability of the moving block's movement is improved, so that the moving block controls the second link to rotate in a direction away from the first link, realizing the function of the second link rotating synchronously during the rotation of the first link.

[0016] Preferably, the movable block has a control groove that communicates with the clearance groove. The connecting column is rotatably connected to the inner wall of the control groove and controls the movable block to move along the direction of the movable groove. A plurality of balls are embedded in the inner wall of the control groove along its circumference, and each ball abuts against the connecting column.

[0017] By adopting the above technical solution, during the movement of the moving block, the connecting column and the inner wall of the control groove rotate and abut against each other. At this time, under the action of the ball, the sliding friction between the connecting column and the inner wall of the control groove is changed into rolling friction, which reduces the friction between the connecting column and the inner wall of the control groove, and provides convenience for the connecting column to drive the reversing gear to rotate more stably.

[0018] Preferably, the driving assembly includes a motor, a drive shaft, a drive gear, a driven gear, and a drive rod. The motor is disposed in the driving cavity. The drive shaft is coaxially disposed on the motor's rotating shaft. The drive gear is coaxially disposed on the drive shaft. The driven gear is coaxially disposed on the rotating shaft of the display assembly. The drive rod is slidably connected in the driving cavity in the vertical direction and is disposed between the drive gear and the driven gear. A first rack is provided on the side of the drive rod near the drive gear, and the first rack meshes with the drive gear. A second rack is provided on the side of the drive rod near the driven gear, and the second rack meshes with the driven gear. The inner wall of the driving cavity is provided with a limiting member that cooperates with the control assembly. When the display assembly rotates to a designated position, the limiting member connects with the control assembly, and the drive gear separates from the first rack.

[0019] By adopting the above technical solution, when it is necessary to control the rotation of the display component, the operator starts the motor, the motor drives the drive shaft to rotate, the drive shaft drives the gear to rotate, the drive gear contacts the first rack and drives the first rack to move away from the display component, the first rack drives the drive rod to move away from the display component, and at the same time the drive rod drives the second rack to move away from the display component, the second rack then drives the driven gear to rotate, the driven gear rotates and drives the display component to rotate away from the moving vehicle body, so that the display component tilts. When the drive gear separates from the first rack, the control component contacts the limiting component, the limiting component provides a limit for the display component, and the tilting of the display component is completed so that the operator can observe the test results.

[0020] Preferably, the control component includes a first control board, which is disposed on the rotation shaft of the display component and in the drive cavity;

[0021] The limiting component includes an electromagnetic plate, which is embedded in the inner wall of the drive cavity. When the drive gear separates from the first rack, the electromagnetic plate attracts the first control plate.

[0022] By adopting the above technical solution, during the rotation of the display component, the first control board rotates toward the direction of the electromagnetic plate. When the drive gear separates from the first rack, the electromagnetic plate attracts the first control board. Under the combined action of the first control board and the electromagnetic plate, the display component is not easy to reset under its own gravity, and the tilting of the display component is completed, which provides convenience for the operator to observe the detection value.

[0023] Preferably, the starting assembly includes a starting shaft, a first gear, and a second gear. The starting shaft is rotatably connected in the drive cavity, and the axis of the starting shaft is collinear with the axis of the drive shaft. The first gear is coaxially mounted on the starting shaft, and the second gear is coaxially mounted on the rotating shaft of the first connecting rod. A third connecting belt is wound around the first and second gears. A first bevel gear is coaxially mounted on the end of the drive shaft away from the drive gear, and a second bevel gear is coaxially mounted on the end of the starting shaft away from the first gear. A second control plate is mounted on the rotating shaft of the display assembly. The second control plate is perpendicular to the first control plate, and a transition bevel gear is rotatably connected to the side of the second control plate away from the display assembly. Both the first and second bevel gears mesh with the transition bevel gear.

[0024] By adopting the above technical solution, during the rotation of the display component, both the first control board and the second control board rotate toward the electromagnetic plate. The second control board drives the adapter bevel gear to move toward the first bevel gear and the second bevel gear. When the first control board attracts the electromagnetic plate, the adapter bevel gear meshes with the first bevel gear and the second bevel gear. Under the action of the motor and the drive shaft, the first bevel gear rotates, which in turn drives the adapter bevel gear to rotate, which in turn drives the second bevel gear to rotate, which in turn drives the first gear to rotate, which in turn drives the third connecting belt to rotate, which in turn drives the second gear to rotate, which in turn drives the starter shaft to rotate, which in turn drives the first connecting rod to move away from the moving vehicle body. This realizes the function of moving the first and second connecting rods after the display component is in place, providing convenience for the operator to control the rotation of the first and second connecting rods, and reducing the possibility of danger caused by the operator moving to the area to be tested.

[0025] Preferably, the mobile vehicle body is provided with a buffer assembly, which includes a plurality of gas springs. Each gas spring is disposed between the display component and the mobile vehicle body. One end of each gas spring is rotatably connected to the end of the display component near the mobile vehicle body, and the other end is rotatably connected to the mobile vehicle body.

[0026] By adopting the above technical solution, when the display component rotates in a direction away from the moving vehicle body, the display component drives the output end of the gas spring to extend and drive the gas spring to rotate. After the test is completed, the operator reverses the motor, causing the first and second connecting rods to retract. At the same time, the operator de-energizes the electromagnetic plate. At this time, the first control board separates from the electromagnetic plate. Under the gravity of the display component, the drive rod, the first control board, and the second control board, the display component resets itself. The gas spring provides a buffer for the display component, making it less likely for the display component to reset too quickly and be damaged.

[0027] Preferably, a wiring assembly is provided between the display component and the detection component. The wiring assembly includes a wiring rod and a winding post. The connecting rod is rotatably connected to the moving vehicle body. The wiring rod is disposed between the display component and the detection component. A storage cavity is opened in the wiring rod. The winding post is rotatably connected to the storage cavity. A signal wire is wound on the winding post. One end of the signal wire is connected to the display component and the other end is connected to the detection head.

[0028] By adopting the above technical solution, when the detection device needs to detect the area to be detected, the operator pulls one end of the signal cable to connect one end of the signal cable to the display component, and then pulls the other end of the signal cable to connect to the detection head. During the process of the operator pulling the signal cable, the signal cable drives the winding post to rotate, so that the two ends of the signal cable can be connected to the display component and the detection head respectively. At the same time, during the movement of the first link and the second link, the end of the signal cable away from the display component moves, and the connecting rod and the winding post rotate, reducing the possibility of the signal cable getting stuck between the winding post and the winding post, and providing convenience for the detection head to detect the area to be detected more stably.

[0029] Preferably, a torsion spring is wound on the rotating shaft of the winding post, with one end of the torsion spring connected to the winding post and the other end connected to the inner wall of the storage cavity.

[0030] By adopting the above technical solution, when the operator connects both ends of the signal line to the display component and the detection head respectively, the signal line drives the winding post to rotate, at which time the torsion spring is in a compressed state; after the detection is completed, the operator separates the signal line from the display component and the detection head, and under the action of the torsion spring's rebound force, the winding post rotates and causes the signal line to be rewound onto the winding post, realizing automatic winding of the signal line, reducing the operator's manual winding steps, and thus further improving the operator's detection efficiency.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. By setting up a first link, a second link, and a connecting assembly, as the first link moves away from the mobile vehicle body, the second link rotates synchronously with the first link under the action of the connecting assembly. At this time, the detection head and the spray head move towards the area to be detected. Then, by controlling the movement of the mobile vehicle body, the area to be detected is detected. This reduces the steps for the operator to move to the area to be detected, making the operator less likely to be injured, and at the same time improving the detection accuracy of the detection device.

[0033] 2. By setting a rotatable display component, when the area to be inspected needs to be inspected, the operator first controls the display component to rotate in a direction away from the moving vehicle body, so that the display component is tilted relative to the moving vehicle body, which provides convenience for the operator to observe the inspection value;

[0034] 3. By setting up control and start components, after the display component rotates to the designated position, the control and start components are activated and control the first and second links to move toward the area to be detected, providing convenience for operators to control the movement of the first and second links.

Detailed Implementation

[0045] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0046] This application discloses a non-destructive testing device for reinforced concrete structures. (Refer to...) Figure 1A non-destructive testing device for reinforced concrete structures includes a mobile vehicle body 1, a detection component 2 and a display component 3 on the mobile vehicle body 1, the detection component 2 and the display component 3 are arranged side by side on the mobile vehicle body 1, a drive cavity 11 is provided in the mobile vehicle body 1, a drive component 4 for driving the display component 3 to rotate is provided in the drive cavity 11, a control component 6 is provided on the rotation shaft of the display component 3, and a starting component 5 for driving the detection component 2 to move is provided in the drive cavity 11. When the area to be inspected needs to be inspected, the operator controls the mobile vehicle body 1 to move to the designated position, and then starts the drive component 4. The drive component 4 drives the display component 3 to rotate away from the mobile vehicle body 1. When the display component 3 rotates to the designated position, the drive component 4 separates from the display component 3. At the same time, the control component 6 connects the drive component 4 and the starting component 5. The starting component 5 then controls the detection component 2 to move towards the area to be inspected, so that the detection component 2 is in contact with the area to be inspected. The operator then controls the mobile vehicle body 1 to move to inspect the area to be inspected. At this time, the tilted component makes it easier for the operator to observe the detection value, so that the operator does not need to be distracted by observing the detection result. At the same time, under the action of the detection component 2, the possibility of danger caused by the operator moving to the area to be inspected is reduced.

[0047] Reference Figure 1 and Figure 2 The display component 3 includes a rotating plate 31 and a display screen 32 for displaying the detection value of the detection component 2. The rotating plate 31 is rotatably connected to the mobile vehicle body 1, and the display screen 32 is embedded on the side of the rotating plate 31 away from the mobile vehicle body 1.

[0048] The drive assembly 4 includes a motor 41, a drive shaft 42, a drive gear 43, a driven gear 44, and a drive rod 45. The motor 41 is fixed in the drive cavity 11. The drive shaft 42 is coaxially fixed on the output end of the motor 41. The drive gear 43 is coaxially fixed on the drive shaft 42. The driven gear 44 is coaxially fixed on the rotating shaft of the rotating plate 31. The drive rod 45 is reciprocally slidably connected in the drive cavity 11 in the vertical direction. A first rack 451 is fixed in the vertical direction on the side of the drive rod 45 near the drive gear 43. A second rack 452 is fixed in the vertical direction on the side of the drive rod 45 near the driven gear 44. The drive gear 43 meshes with the first rack 451, and the driven gear 44 meshes with the second rack 452.

[0049] Reference Figure 3 and Figure 4The control component 6 includes a first control board 61, which is fixed on the rotation shaft of the rotating plate 31. The inner wall of the drive cavity 11 is provided with a limiting member 12 that cooperates with the first control board 61. The limiting member 12 includes an electromagnetic plate 121, which is embedded in the inner wall of the drive cavity 11. When the display screen 32 rotates to the designated position, the drive gear 43 separates from the first rack 451, and at this time the electromagnetic plate 121 attracts the first control board 61.

[0050] When the area to be tested needs to be tested, the operator starts the motor 41. The motor 41 drives the drive shaft 42 and the drive gear 43 to rotate. The drive gear 43 drives the first rack 451 to move downward. The first rack 451 then drives the drive rod 45 and the second rack 452 to move downward. The second rack 452 then drives the driven gear 44 to rotate. The rotation of the driven gear 44 causes the rotating plate 31 to rotate away from the moving vehicle body 1. The rotating plate 31 drives the display screen 32 to rotate away from the moving vehicle body 1. The rotating plate 31 also drives the first control plate 61 to move towards the electromagnetic plate 121. When the drive gear 43 separates from the first rack 451, the electromagnetic plate 121 is activated and attracts the first control plate 61. At this time, the electromagnetic plate 121 and the first control plate 61 cooperate, reducing the possibility of the rotating plate 31 and the display screen 32 resetting under their own gravity. This causes the display screen 32 to tilt, which provides convenience for the operator to observe the test values ​​of the test component 2.

[0051] Reference Figure 3 A buffer assembly 8 is provided on the side of the rotating plate 31 near the moving vehicle body 1. The buffer assembly 8 includes several gas springs 81. One end of the gas spring 81 is rotatably connected to the side of the rotating plate 31 near the moving vehicle body 1, and the other end is rotatably connected to the moving vehicle body 1. During the rotation of the rotating plate 31, each gas spring 81 rotates with the rotating plate 31 and is in an extended state. After the detection assembly 2 completes the detection, the operator closes the electromagnetic plate 121. At this time, under the gravity of the rotating plate 31, the display screen 32 and the first control plate 61, the rotating plate 31 rotates towards the moving vehicle body 1. Under the action of the gas springs 81, the reset speed of the rotating plate 31 and the display screen 32 is slowed down, thus achieving buffering of the rotating plate 31 and the display screen 32 and reducing the possibility of damage to the rotating plate 31 and the display screen 32.

[0052] Reference Figure 5The starting assembly 5 includes a starting shaft 51, a first gear 52, and a second gear 53. The starting shaft 51 is rotatably connected in the drive cavity 11, and the axis of the starting shaft 51 is coaxial with the axis of the drive shaft 42. The starting shaft 51 is located on the side of the drive shaft 42 away from the motor 41. A first bevel gear 421 is coaxially fixed to the end of the drive shaft 42 away from the drive gear 43, and a second bevel gear 55 is coaxially fixed to the end of the starting shaft 51 near the drive shaft 42. A second control plate 62 is fixed on the rotation shaft of the rotating plate 31. The first control plate 61 is perpendicularly arranged, and the second control plate 62 is rotatably connected to the adapter bevel gear 621. When the first control plate 61 is attracted to the electromagnetic plate 121, the first bevel gear 421 and the second bevel gear 55 simultaneously mesh with the adapter bevel gear 621. The first gear 52 is coaxially fixed to the end of the starter shaft 51 away from the second bevel gear 55, and the second gear 53 is coaxially fixed to the rotating shaft of the detection component 2. A third connecting belt 54 is wound around the first gear 52 and the second gear 53. In this embodiment, the third connecting belt 54 is a chain.

[0053] Reference Figure 6 and Figure 7 The detection component 2 includes a first connecting rod 21 and a second connecting rod 22. The first connecting rod 21 is rotatably connected to the mobile vehicle body 1, and the rotation directions of the first connecting rod 21 and the rotating plate 31 are opposite. The second gear 53 is coaxially fixed on the rotating shaft of the first connecting rod 21. The second connecting rod 22 is rotatably connected to the end of the first connecting rod 21 away from the mobile vehicle body 1. The end of the second connecting rod 22 away from the first connecting rod 21 is ball-jointed with a detection plate 221. On the side of the detection plate 221 away from the second connecting rod 22, a detection head 222 and a spray head 223 for spraying coupling agent are fixed side by side. The spray head 223 and the detection head 222 are arranged sequentially along the moving direction of the mobile vehicle body 1. The first connecting rod 21 and the second connecting rod 22 are connected by a connecting component 7.

[0054] During the rotation of the rotating plate 31, the second control plate 62 and the transition bevel gear 621 move toward the first bevel gear 421 and the second bevel gear 55. When the first control plate 61 is attracted to the electromagnetic plate 121, the transition bevel gear 621 meshes with the first bevel gear 421 and the second bevel gear 55. At the same time, the drive gear 43 disengages from the first rack 451. At this time, the drive shaft 42 drives the first bevel gear 421 to rotate, the first bevel gear 421 drives the transition bevel gear 621 to rotate, the transition bevel gear 621 drives the second bevel gear 55 to rotate, and the second bevel gear 55 drives the starter shaft 51 to rotate, thus starting the engine. The shaft 51 rotates and drives the first gear 52 to rotate. The first gear 52 drives the third connecting belt 54 to rotate. The third connecting belt 54 rotates and drives the second gear 53 to rotate. The second gear 53 rotates and drives the first connecting rod 21 to rotate in a direction away from the moving vehicle body 1. Under the action of the connecting component 7, the first connecting rod 21 drives the second connecting rod 22 to rotate in a direction away from the first connecting rod 21. This causes the second connecting rod 22 to drive the detection head 222 and the spray head 223 to move towards the area to be detected, realizing the synchronous movement of the first connecting rod 21 and the second connecting rod 22, and improving the efficiency of the detection device in detecting the area to be detected.

[0055] When the detection head 222 and the spray head 223 come into contact with the area to be tested, the operator uses the spray head 223 to spray out the coupling agent. At this time, the operator controls the moving vehicle body 1 to move, and the detection head 222 comes into contact with the coupling agent and tests the area to be tested. At the same time, the display screen 32 displays the value detected by the detection head 222. Under the action of the first link 21 and the second link 22, the possibility of the operator moving to the area to be tested on their own and causing danger is reduced, which provides a certain guarantee for the personal safety of the operator. At the same time, it reduces the possibility of the operator being distracted by observing the detection value on the display screen 32, which may cause errors in the detection results.

[0056] Reference Figure 7 A roller 225 is rotatably connected to the detection plate 221. When the second link 22 comes into contact with the area to be detected, the roller 225 abuts against the area to be detected. When the moving vehicle body 1 moves, the roller 225 moves along the area to be detected. Under the action of the roller 225, the stability of the detection plate 221 when it moves is improved, so that the detection head 222 can detect the area to be detected more stably.

[0057] Reference Figure 6 and Figure 8 The connecting component 7 includes a connector 71 and a control component 72. One end of the connector 71 is connected to the mobile vehicle body 1 and the other end is connected to the first connecting rod 21. One end of the control component 72 is connected to the connector 71 and the other end is connected to the second connecting rod 22.

[0058] The connector 71 includes a first connecting wheel 711 and a second connecting wheel 712. The first connecting wheel 711 is fixed on the mobile vehicle body 1. The axis of rotation of the first connecting wheel 711 is in the same straight line as the axis of rotation of the first connecting rod 21. The second connecting wheel 712 is rotatably connected to the first connecting rod 21. The second connecting wheel 712 is located at one end of the first connecting rod 21 near the second connecting rod 22. A first connecting belt 713 is wound around the first connecting wheel 711 and the second connecting wheel 712. In this embodiment, the first connecting wheel 711 and the second connecting wheel 712 are configured as gears, and the first connecting belt 713 is configured as a chain.

[0059] The control component 72 includes a first control wheel 721, a second control wheel 722, and a moving block 723. The first control wheel 721 is coaxially mounted on the second connecting wheel 712. The second connecting rod 22 has a moving groove 224 along its own length direction. The moving block 723 is slidably connected in the moving groove 224, and a connecting post 724 is rotatably connected to the moving block 723. The second control wheel 722 is coaxially fixed to the end of the connecting post 724 away from the moving block 723. A second connecting belt 725 is wound around the first control wheel 721 and the second control wheel 722. In this embodiment, both the first control wheel 721 and the second control wheel 722 are gears, and the second connecting belt 725 is a chain. The first connecting wheel 711 and the second connecting wheel 712 have the same diameter, and the first control wheel 721 and the second control wheel 722 have the same diameter. The diameter of the first connecting wheel 711 is larger than the diameter of the first control wheel 721 in order to improve the transmission capacity of the second connecting wheel 712.

[0060] Reference Figure 6 and Figure 9 The moving groove 224 is provided with a guide member 24, which includes a guide rack 241, a reversing gear 242, and a moving gear 243. The guide rack 241 is fixed in the moving groove 224 along the length of the second connecting rod 22. The moving block 723 is slidably connected to the guide rack 241. A clearance groove 726 is provided on the side of the moving block 723 near the guide rack 241. A control groove 727 communicating with the clearance groove 726 is provided on the side of the moving block 723 near the connecting post 724. The connecting post 724 extends into the clearance groove 726 and is rotatably connected to the inner wall of the clearance groove 726. The reversing gear 242 is coaxially fixed on one end of the connecting post 724 located in the clearance groove 726. The moving gear 243 is rotatably connected to the inner wall of the clearance groove 726, and one side of the moving gear 243 meshes with the reversing gear 242 and the other side meshes with the guide rack 241.

[0061] During the process of the second gear 53 controlling the rotation of the first connecting rod 21, the first connecting rod 21 drives the second connecting wheel 712 to rotate in a direction away from the moving vehicle body 1. Under the action of the constant length of the first connecting belt 713, the first connecting belt 713 rotates around the first connecting wheel 711. At this time, the second connecting wheel 712 rotates and drives the first control wheel 721 to rotate. The first control wheel 721 rotates and drives the second connecting belt 725 to rotate. The second connecting belt 725 rotates and drives the second control wheel 722 to rotate. The second control wheel 722 drives the connecting column 724 to rotate. 4. The reversing gear 242 rotates, driving the moving gear 243 to rotate. The rotation of the moving gear 243 causes the moving block 723 to move along the guide rack 241. The moving block 723 abuts against the inner wall of the moving groove 224 and drives the second connecting rod 22 to rotate away from the first connecting rod 21. The rotation of the second connecting rod 22 causes the detection plate 221, the detection head 222, and the spray head 223 to move towards the area to be detected, so as to detect the area to be detected. This eliminates the need for the operator to walk to the area to be detected, reducing the possibility of danger to the operator. At the same time, it provides convenience for the operator to detect the area to be detected.

[0062] Reference Figure 9 The inner wall of the control groove 727 is embedded with a number of balls 73 along its circumference. Each ball 73 abuts against the connecting column 724. During the rotation of the connecting column 724, the balls 73 change the sliding friction between the connecting column and the inner wall of the control groove 727 into rolling friction, reducing the friction between the connecting column 724 and the inner wall of the control groove 727. This allows the connecting column 724 to control the rotation of the reversing gear 242 more stably. When the moving block 723 moves, the connecting column 724 abuts against the inner wall of the control groove 727. Under the action of the balls 73, the wear between the connecting column 724 and the inner wall of the control groove 727 is reduced, which facilitates the connecting column 724 to control the movement of the moving block 723.

[0063] Reference Figure 1 and Figure 2 A wiring assembly 9 is provided between the rotating plate 31 and the first connecting rod 21. The wiring assembly 9 includes a wiring rod 91 and a winding post 92. The wiring rod 91 is rotatably connected to the moving vehicle body 1 and is located between the rotating plate 31 and the first connecting rod 21. A storage cavity 911 is provided in the wiring rod 91. The winding post 92 is rotatably connected in the storage cavity 911. A torsion spring 94 is wound on the rotating shaft of the winding post 92. One end of the torsion spring 94 is fixed to the inner wall of the storage cavity 911 and the other end is fixed to the winding post 92. A signal line 93 is wound on the winding post 92. One end of the signal line 93 passes through the rotating plate 31 and is fixed to the display screen 32, and the other end is fixed to the detection head 222.

[0064] When the operator needs to use the testing device to test the area to be tested, the operator pulls one end of the signal line 93, causing the winding post 92 to rotate. At this time, the torsion spring 94 is in a compressed state. The operator passes one end of the signal line 93 through the rotating plate 31 and connects it to the display screen 32. Then, the operator pulls the other end of the signal line 93, fixing it to the detection head 222, thus completing the connection between the display screen 32 and the detection head 222. During the movement of the detection head 222 controlled by the second connecting rod 22, the detection head 222 moves one end of the signal line 93. At this time, the connecting rod 91... Both the winding post 92 and the signal wire 93 rotate, making it less likely for the signal wire 93 to get stuck and reducing the possibility of the signal wire 93 separating from the detection head 222, so that the signal wire 93 can transmit the detection results more stably. After the detection is completed, the operator separates one end of the signal wire 93 from the detection head 222 and the other end of the signal wire 93 from the display screen 32. Under the action of the torsion spring 94, the winding post 92 rotates and the signal wire 93 is automatically wound around the winding post 92, reducing the step of the operator manually winding the signal wire 93, thereby improving the efficiency of the operator in using the detection device to detect the area to be detected.

[0065] The implementation principle of the non-destructive testing device for reinforced concrete structures in this embodiment is as follows: The operator controls the mobile vehicle body 1 to move to the area to be tested, and then starts the drive component 4. The drive component 4 drives the display component 3 to rotate. When the first control plate 61 rotates to be attracted to the electromagnetic plate 121, the drive component 4 connects with the starting component 5 and drives the starting component 5 to start. The starting component 5 drives the first connecting rod 21 to rotate away from the mobile vehicle body 1. At this time, under the action of the connecting component 7, the second connecting rod 22 rotates away from the first connecting rod 21, realizing the function of synchronous rotation of the first connecting rod 21 and the second connecting rod 22. This improves the efficiency of the operator in using the testing device to test the area to be tested, and at the same time reduces the possibility of accidents when the operator moves to the area to be tested and performs testing, providing a certain guarantee for the personal safety of the operator. Moreover, under the action of the tilted display component 3, it provides convenience for the operator to observe the test values. Furthermore, under the cooperation of the display component 3 and the mobile vehicle body 1, it reduces the possibility of the operator being distracted in observing the test values ​​and causing testing errors.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
