Description

Technical Field

[0001] The present application relates to the technical field of detection devices, and in particular to a device for detecting surface defects of bridges and roads. Background Art

[0002] Previously, surface defect detection for bridges and roads relied primarily on manual visual inspection, which was inefficient and posed safety risks. With technological advancements, some automated inspection equipment has been introduced. Currently, there are some detectors on the market that use image recognition or laser ranging as bridge and road surface defect detection equipment. These detectors use cameras to capture images and then analyze them using image processing technology, or use laser rangefinders to obtain data and analyze the road surface conditions through processing and analysis, allowing subsequent surface finishing to achieve the desired smoothness.

[0003] However, when these detectors are used outdoors or indoors with high light intensity, they are greatly affected by strong light, which has a significant impact on the clarity of the image captured by the camera or the laser emitted and received by the laser ranging. When there are stains on the surface, it will also be affected, resulting in a large error in the detection accuracy of the detector, so further improvement is needed. Utility Model Content

[0004] In order to reduce the impact on detection accuracy, the present application provides a bridge and road surface defect detection device.

[0005] This application provides a bridge and road surface defect detection device, which adopts the following technical solution:

[0006] A device for detecting defects in the surface layer of a bridge road comprises a bracket, a detector that slides along the length direction of the bracket, a driving assembly arranged on the bracket to drive the detector to slide, a blocking assembly arranged on the detector to block external light, and a cleaning assembly that is slidably connected to the bracket to clean surface materials; the blocking assembly comprises a first baffle that rotates around the axis of the detector and a third limiter that limits the rotation of the first baffle, the first baffle being arranged in an arc shape in a direction away from the detector, and the cleaning assembly comprising a scraper that abuts against the road surface and an elastic member that pushes the scraper to move toward the surface.

[0007] By adopting the above technical solution, the bracket is placed on both sides of the surface to be inspected. After placement, the first baffle is rotated to the corresponding position according to the direction of external light to block the light. After the third limiter is used to limit the rotation, the drive assembly is started to drive the detector to slide along the length of the bracket. The baffle is set on the detector and can move with the detector to reduce the impact of strong light on the position to be inspected by the detector, which may affect the detector's detection of surface defects. Before the detector performs inspection, the scraper is used to clean impurities attached to the surface to reduce the impact of impurities covering the depressions on the road surface on the detection accuracy.

[0008] Preferably, the bracket includes two support columns and a support rod arranged on the support columns for the detector to slide, and the support rod includes a first support rod, a second support rod slidably connected to the first support rod, and a second limiter to limit the sliding of the second support rod.

[0009] By adopting the above technical solution, the length of the support rods can be adjusted by the first support rod, the second support rod and the second limiter, so as to adapt to the detection of surface defects of roads with different widths. It is also convenient to shorten and carry or store it.

[0010] Preferably, the bracket includes a sliding rod that is slidably arranged on the upper end surface of the support column, the support rod is arranged between the two sliding rods, and the support column is provided with a third limiting member that limits the sliding of the sliding rod.

[0011] By adopting the above technical solution, when the bottom surface is relatively uneven, the heights of the support columns at both ends are different, which causes errors in the detected data and affects the flatness during subsequent leveling and repair. Therefore, a sliding rod and a third limiter are provided to adjust the horizontality of the support rod to obtain more accurate detection accuracy for the subsequent plane finishing effect.

[0012] Preferably, a second slide groove is provided on the lower surface of the first support rod along its own length direction, the second support rod is slidably sleeved on the first support rod, a third slide groove is provided on the lower surface of the second support rod along its own length direction, the third slide groove is connected to the second slide groove, and a first slider is protruding from the upper end surface of the detector and is slidably connected to the second slide groove, and the first slider is slidably connected to the third slide groove.

[0013] By adopting the above technical solution, for the support rod that can be extended and adjusted, since the detector slides along the length direction of the support rod, a second sliding groove and a third sliding groove that are interconnected are provided to allow the first slider provided on the detector to slide.

[0014] Preferably, the driving assembly includes two connecting ropes respectively fixedly connected to the two side walls of the first sliding block away from the first support rod, two rotating rods respectively connected to the two connecting ropes, and two driving parts respectively driving the two rotating rods to rotate, the connecting ropes are wound around the rotating rods, the connecting ropes are built into the second slide groove and the third slide groove, the two first rotating rods are respectively rotatably connected to the first support rod and the second support rod, and extend to the second slide groove and the third slide groove respectively.

[0015] By adopting the above technical solution, two connecting ropes are provided. When the support rod needs to be adjusted, the driving parts relative to the two rotating rods are started respectively to reel in or unreel the two connecting ropes respectively, so that the lengths of the two connecting ropes are adapted to the lengths of the support rods. When the detector slides, the two rotating rods respectively unreel and reel in the two connecting ropes to slide along the length direction of the bracket.

[0016] Preferably, the blocking assembly further includes a second baffle disposed below the first baffle, and the second baffle is disposed obliquely downward in a direction away from the detector.

[0017] By adopting the above technical solution, when the surface is uneven, there will be a certain gap between the first baffle and the surface of the bridge road. Some light will pass obliquely through the gap between the first baffle and the surface to illuminate the place where the detector is detecting. Therefore, by providing a second baffle, since the second baffle is inclined downward in the direction away from the detector, the blocking effect of external strong light can be increased to reduce the impact on the detector during detection.

[0018] Preferably, the cleaning assembly includes a plate body for mounting the scraper, a fourth sliding groove for sliding and inserting the plate body is provided on the lower surface of the plate body, and the elastic member is built into the fourth sliding groove.

[0019] By adopting the above technical solution, the elasticity of the elastic member itself is used to push the scraper against the surface of the bridge road to clean impurities attached to the surface, thereby reducing the impact on the detection accuracy of subsequent detectors.

[0020] Preferably, a plurality of elastic members are spaced apart along the length direction of the fourth chute, and the scraper includes a silicone plate slidably inserted in the fourth chute and a plurality of silicone strips arranged on the surface of the silicone plate away from the plate body.

[0021] By adopting the above technical solution, since the surface layer may be uneven, by providing a number of elastic parts and correspondingly providing a number of silicone strips, the fit between the surface layer and the surface layer can be relatively improved, thereby improving the cleaning effect of the surface layer.

[0022] In summary, the present invention has the following beneficial effects:

[0023] The bracket is placed on both sides of the surface to be inspected. After placement, the first baffle is rotated to the corresponding position according to the direction of external light to block the light. After the third limiter is used to limit the rotation, the drive assembly is started to drive the detector to slide along the length of the bracket. The baffle is set on the detector and can move with the detector to reduce the impact of strong light on the location to be inspected by the detector, which may affect the detection of surface defects by the detector. Before the detector conducts inspection, the scraper is used to clean impurities attached to the surface to reduce the impact of impurities covering the depressions on the road surface on the detection accuracy.
