Description

Technical Field

[0001] The invention relates to the technical field of road flaw detection, in particular to a measuring device for road flaw detection. Background Art

[0002] As the cornerstone of road maintenance, road flaw detection widely uses cutting-edge non-destructive testing technologies such as ground penetrating radar, ultrasound, infrared imaging and radiographic flaw detection. These technologies can not only deeply analyze and accurately locate hidden defects such as cracks, cavities and peeling inside the road without destroying the road structure, but also effectively improve the accuracy and efficiency of road safety monitoring. By timely discovering and dealing with these potential threats, road flaw detection technology provides strong technical support for preventing road collapse, reducing traffic accident risks, optimizing maintenance strategies and improving capital utilization efficiency. When conducting road flaw detection, staff will use infrared flaw detection devices to conduct road flaw detection.

[0003] Infrared flaw detection devices detect the condition of road materials by emitting infrared radiation and receiving its reflected or transmitted signals. These signals contain the temperature distribution information of road materials, and the change of temperature distribution is often related to the internal structure and defect state of the material. Since infrared flaw detection devices judge road damage by temperature distribution information, when road flaw detection is carried out under conditions of strong wind, wind speed convection cooling will cause the temperature of defective equipment or road areas to be accelerated, thereby reducing the temperature at the defect.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figure 1-4 , the present invention provides a technical solution:

[0036] A measuring device for road flaw detection, comprising a vehicle body 1, a mounting frame 2 and an infrared flaw detector 3, and further comprising: a baffle 4, the baffle 4 being located on the mounting frame 2, and being used to block wind blowing toward the infrared flaw detector 3 when the infrared flaw detector 3 performs road flaw detection;

[0037] A shielding component 5, wherein the shielding component 5 is arranged on the mounting frame 2, and the baffle plate 4 is arranged on the shielding component 5, and when the infrared flaw detector 3 performs road flaw detection, the baffle plate 4 is controlled to rotate around the infrared flaw detector 3 by the shielding component 5 to block the wind blowing toward the infrared flaw detector 3;

[0038] The benefit of setting up the shielding component 5 is that it can drive the baffle 4 to block the wind blowing towards the infrared flaw detector 3 during the inspection process. The baffle 4 not only blocks the external wind direction changes, but also forms a stable wind curtain by guiding the airflow, thereby providing a relatively stable working environment for the infrared flaw detector 3, which helps to reduce the scattering and reflection of infrared light caused by airflow fluctuations, thereby improving the accuracy and stability of flaw detection. At the same time, the stable airflow environment also helps to reduce the temperature fluctuation around the infrared flaw detector 3. The temperature fluctuation may affect the temperature distribution of the road and its surrounding environment. This temperature change will mask or reduce the actual characteristics of the road defects and increase the difficulty of detection. By maintaining temperature stability, it helps to increase the detection accuracy of the infrared flaw detector 3.

[0039] The isolation component 8 is arranged on the shielding component 5, and is used to guide the airflow blowing toward the baffle 4 to form a wind curtain, thereby isolating the infrared flaw detector 3 from the dust in the air blown by the wind.

[0040] The advantage of setting up the isolation component 8 is that it can guide the wind blowing toward the baffle 4 to form a wind curtain to isolate the dust in the air. Road infrared flaw detection is usually carried out outdoors, and there may be a large amount of dust in the environment. If the dust is blown onto the infrared flaw detector 3 by the wind, it may be deposited on the lens or sensor surface of the probe, affecting the transmission and reception of infrared light, thereby reducing the accuracy and reliability of flaw detection. The baffle 4 effectively isolates most of the dust by forming a wind curtain, reducing its deposition on the infrared flaw detector 3. At the same time, in a humid environment, if the surface temperature of the infrared flaw detector 3 is lower than the dew point, water vapor in the air may condense into water droplets on its surface, further affecting the transmission of infrared light. The baffle 4 helps to reduce the risk of water vapor condensation by keeping the airflow around the infrared flaw detector 3 stable.

[0041] The shielding assembly 5 includes a sensing member 6 disposed on the mounting frame 2, and the sensing member 6 is used to sense the wind direction. The mounting frame 2 is provided with a driving member 7, and the driving member 7 is used to drive the baffle plate 4 to rotate.

[0042] The induction member 6 comprises a rotating shaft 61 rotatably arranged on the mounting frame 2 , a wind direction rod 62 is arranged on the rotating shaft 61 , a wind direction plate 63 is arranged at one end of the wind direction rod 62 , and a push plate 64 is arranged at one end of the rotating shaft 61 away from the wind direction rod 62 .

[0043] The benefit of the sensor 6 is that it can automatically adjust the direction of the baffle 4 according to the change of wind direction in the environment, thereby improving the protection of the infrared flaw detector 3.

[0044] The driving member 7 includes an annular plate 71 arranged on the mounting frame 2, a mounting plate 72 is arranged on the annular plate 71, and the mounting plate 72 is connected to the infrared flaw detector 3. A rotating groove 73 is provided in the annular plate 71, a guide groove 74 is provided in the rotating groove 73, a ball 75 is movably provided in the guide groove 74, a rotating plate 76 is slidably provided in the rotating groove 73, one side of the rotating plate 76 is in contact with the ball 75, a connecting groove 77 is provided on the rotating groove 73, the push plate 64 passes through the connecting groove 77 and is connected to the rotating plate 76, and the push plate 64 is slidably connected to the connecting groove 77, a mounting ring 78 is provided on the rotating plate 76, and the mounting ring 78 is connected to the baffle 4.

[0045] The guide groove 74 and the ball bearing 75 make it easier for the wind direction rod 62 to drive the baffle plate 4 to rotate, thereby improving the sensitivity of the baffle plate 4.

[0046] During the process of infrared flaw detection of roads, when the external environment is windy, the wind direction plate 63 is first blown to rotate, which further drives the wind direction rod 62 to rotate. The rotation of the wind direction rod 62 drives the push plate 64 to rotate at the same time. The rotation of the push plate 64 drives the rotating plate 76 connected thereto to rotate. At this time, driven by the rotating plate 76, the baffle plate 4 connected to the rotating plate 76 rotates to the front of the wind direction to block the wind, thereby avoiding forced convection on the front of the wind direction, causing temperature loss at the road flaw detection position, and affecting the accuracy of road flaw detection.

[0047] The isolation assembly 8 includes a guide member 9 arranged on the baffle plate 4, through which the airflow is guided to form a wind curtain, an adjusting member 10 is arranged on the guide member 9, and the angle of the wind curtain is adjusted by the adjusting member 10, and a synchronous member 11 is arranged on the adjusting member 10, and multiple adjusting members 10 are driven to rotate synchronously by the synchronous member 11, and a power member 12 is arranged on the mounting frame 2, and the power member 12 provides power for the adjustment member 10 to work.

[0048] The guide member 9 includes an airflow compartment 91 opened in the mounting ring 78 and the baffle plate 4, the baffle plate 4 is provided with an air guide groove 92, the baffle plate 4 is provided with an air guide plate 93 at the position of the air guide groove 92, the mounting ring 78 is provided with an extension pipe 94, the extension pipe 94 is connected to the airflow compartment 91, and rotating pipes 95 are rotatably provided on both sides of the extension pipe 94, and the rotating pipe 95 is provided with an air injection pipe 96.

[0049] The benefit of setting up the guide member 9 is that it can guide the wind blowing toward the baffle 4 to form a wind curtain, thereby isolating the dust in the air and preventing the dust from being blown onto the infrared flaw detector 3 and deposited on the lens or sensor surface of the probe, thereby affecting the transmission and reception of infrared light.

[0050] When wind blows toward the baffle 4, it will enter the airflow chamber 91 through the air guide groove 92, then enter the extension tube 94 from the airflow chamber 91, and then be ejected through the rotating tube 95 and the jet pipe 96 on the extension tube 94, thereby forming a wind curtain. The setting of the air guide plate 93 can reduce the wind noise generated when the airflow hits the baffle 4, thereby avoiding the interference of wind noise on infrared flaw detection.

[0051] The adjusting member 10 includes a limit groove 101 provided on the extension tube 94, a limit slider 102 is slidably arranged in the limit groove 101, an adjusting rack 103 is arranged on the limit slider 102, an adjusting gear 104 engaged with the adjusting rack 103 is arranged on the rotating tube 95, a positioning shaft 105 is provided on the extension tube 94, a connecting rod 106 is rotatably arranged on the adjusting rack 103, an adjusting groove 1 107 is provided on the connecting rod 106, the adjusting groove 1 107 is movably connected to the positioning shaft 105, and an adjusting groove 2 108 is provided on the connecting rod 106.

[0052] The advantage of setting the adjustment part 10 is that when the wind force becomes stronger, the jet angle of the jet pipe 96 can be adjusted, thereby improving the wind curtain's ability to isolate dust in the external environment. When the wind force becomes stronger, if the wind curtain angle is not adjusted in time, the wind curtain may be disturbed, affecting its control of the surrounding environment. Turning the jet angle outward can more effectively block the direct impact of external strong winds on the flaw detection area, maintain the relative stability of the flaw detection area, and thus improve the accuracy and efficiency of flaw detection.

[0053] The synchronous member 11 includes a connecting rod 111 slidably arranged on the extension tube 94, and synchronous rods 112 are arranged on both sides of the connecting rod 111. The synchronous rod 112 passes through the adjusting groove 108 and is movably connected with the adjusting groove 108. A fixed plate 113 is arranged on the extension tube 94, and a rotating screw 114 is rotatably arranged on the fixed plate 113. One end of the rotating screw 114 passes through the connecting rod 111 and is threadedly connected with the connecting rod 111. A rotating gear 115 is arranged at the end of the rotating screw 114. A synchronous plate 116 is rotatably arranged on the mounting ring 78, and a synchronous slot 117 engaged with the rotating gear 115 is arranged on the synchronous plate 116.

[0054] The power member 12 includes a positioning plate 121 arranged on the wind direction rod 62, a pressure plate 122 is slidably arranged on the wind direction rod 62, a buffer spring 123 is sleeved between the pressure plate 122 and the positioning plate 121, and the two ends of the buffer spring 123 are respectively connected to the pressure plate 122 and the positioning plate 121, a power shaft 124 is rotatably arranged on the mounting frame 2, a spring box 125 is arranged on the mounting frame 2, the power shaft 124 passes through the spring box 125 and is rotatably connected to the spring box 125, a spring spring 126 is arranged in the spring box 125, and the spring spring One end of the spring 126 is connected to the power shaft 124, and a winding wheel 128 is provided on the power shaft 124. A traction rope 127 is provided on the winding wheel 128. A guide ring 1212 is provided on the rotating shaft 61. The traction rope 127 passes through the guide ring 1212 and is connected to the pressure plate 122. A connecting shaft 129 is provided on the rotating screw rod 114, and the connecting shaft 129 passes through the mounting frame 2 and is rotatably connected to the mounting frame 2. A power pulley 1210 is provided on the connecting shaft 129 and the power shaft 124, and a power belt 1211 is provided on the power pulley 1210.

[0055] When the wind force in the external environment becomes stronger, the wind force pushes the pressure plate 122 to move on the wind direction rod 62, and the pressure plate 122 moves, driving the traction rope 127 to move, and the movement of the traction rope 127 drives the winding wheel 128 to rotate. The rotation of the winding wheel 128 drives the power shaft 124 to rotate, and the power shaft 124 rotates, driving the power pulley 1210 to rotate, and synchronously drives the connecting shaft 129 to rotate through the power belt 1211. The advantage of setting the clockwork spring 126 is that the traction rope 127 can be rewound when the pressure plate 122 is reset.

[0056] When the linkage shaft 129 rotates, the rotating screw rod 114 is driven to rotate synchronously. The rotating screw rod 114 is driven to rotate the rotating gear 115 arranged thereon. The rotating gear 115 is driven to rotate the synchronous slot 117 engaged with it. The synchronous slot 117 is driven to rotate the synchronous plate 116, and then the synchronous slot 117 on the synchronous plate 116 drives multiple rotating screw rods 114 to rotate synchronously. When the rotating screw rod 114 rotates, it drives the connecting rod 111 threadedly connected to it to move. The movement of the connecting rod 111 drives the synchronous rod 112 to move, thereby driving the connecting rod 106 movably connected to the synchronous rod 112 to rotate around the positioning shaft 105. The connecting rod 106 rotates, pushing the adjusting rack 103 and the limiting slider 102 to move in the limiting slot 101. At this time, the adjusting gear 104 engaged with the adjusting rack 103 rotates under the push of the adjusting rack 103, thereby driving the rotating tube 95 to rotate, so as to adjust the jet angle of the jet tube 96.

[0057] During use, during the process of infrared flaw detection of roads, when the external environment is windy, the wind direction plate 63 is first blown to rotate, which further drives the wind direction rod 62 to rotate. The rotation of the wind direction rod 62 drives the push plate 64 to rotate at the same time. The rotation of the push plate 64 drives the rotating plate 76 connected thereto to rotate. At this time, driven by the rotating plate 76, the baffle plate 4 connected to the rotating plate 76 rotates to the front of the wind direction to block the wind, thereby avoiding forced convection on the front of the wind direction, causing temperature loss at the road flaw detection position, and affecting the accuracy of road flaw detection.

[0058] When the wind blows toward the baffle 4, it enters the airflow chamber 91 through the air guide groove 92, then enters the extension tube 94 from the airflow chamber 91, and is ejected through the rotating tube 95 and the jet pipe 96 on the extension tube 94, thereby forming an air curtain.

[0059] When the wind force in the external environment becomes stronger, the wind force pushes the pressure plate 122 to move on the wind direction rod 62, and the pressure plate 122 moves, driving the traction rope 127 to move, and the movement of the traction rope 127 drives the winding wheel 128 to rotate. The rotation of the winding wheel 128 drives the power shaft 124 to rotate, and the power shaft 124 rotates, driving the power pulley 1210 to rotate, and synchronously drives the connecting shaft 129 to rotate through the power belt 1211. The advantage of setting the clockwork spring 126 is that the traction rope 127 can be rewound when the pressure plate 122 is reset.

[0060] When the linkage shaft 129 rotates, the rotating screw rod 114 is driven to rotate synchronously. The rotating screw rod 114 is driven to rotate the rotating gear 115 arranged thereon. The rotating gear 115 is driven to rotate the synchronous slot 117 engaged with it. The synchronous slot 117 is driven to rotate the synchronous plate 116, and then the synchronous slot 117 on the synchronous plate 116 drives multiple rotating screw rods 114 to rotate synchronously. When the rotating screw rod 114 rotates, it drives the connecting rod 111 threadedly connected to it to move. The movement of the connecting rod 111 drives the synchronous rod 112 to move, thereby driving the connecting rod 106 movably connected to the synchronous rod 112 to rotate around the positioning shaft 105. The connecting rod 106 rotates, pushing the adjusting rack 103 and the limiting slider 102 to move in the limiting slot 101. At this time, the adjusting gear 104 engaged with the adjusting rack 103 rotates under the push of the adjusting rack 103, thereby driving the rotating tube 95 to rotate, so as to adjust the jet angle of the jet tube 96.
