[0023] By setting auxiliary components and adjustment components, when the flatness of the pier body is detected, when encountering pier bodies with different diameters, the moving distance of the first piston rod will increase, so that the moving distance of the second piston rod will increase, and at the same time, the moving distance of the auxiliary rod will increase, so that the auxiliary rod can lift more auxiliary teeth.

When the diameter of the pier body is smaller, the number of auxiliary teeth lifted in the auxiliary tooth group is smaller, and the moving distance of the industrial camera is shorter. During use, it is still possible to take pictures of the entire surface of the pier body, thereby ensuring the integrity of the camera when shooting, and achieving the effect of taking pictures and detecting positions of different thicknesses on the same pier body.

[0024] By setting up the power wheel and the gravity ball, not only can self-locking be achieved during use, but the gravity of the gravity ball can also be used to abut the power wheel against the surface of the pier body, thereby preventing the slide rail from sliding down the pier body surface. At the same time, manpower is liberated, and manual climbing of the pier body and high-altitude operations are avoided, thereby reducing the occurrence of danger and protecting the safety of operators.

[0042] like Figures 1 to 9As shown, an embodiment of the present invention provides a pier body flatness detection device based on visual technology, including a slide rail 1, wherein the slide rail 1 is provided with multiple groups, and two adjacent slide rails 1 are detachably connected by bolts, and the multiple groups of slide rails 1 surround the pier body, and a slide plate 2 is slidably connected to the slide rail 1, and a support rod 3 is slidably connected to the bottom of the slide rail 1, and one end of the support rod 3 is connected to a gravity ball 4 through a traction rope, and a sleeve is fixedly connected to the bottom of the slide rail 1, and the gravity ball 4 is movably connected to the inside of the sleeve, and the other end of the support rod 3 is fixedly connected to a power wheel 5, and the bottom of the power wheel 5 is connected to an auxiliary wheel through the support rod 3, and the surface of the slide plate 2 is provided with a connecting plate An industrial camera 6 is connected through an adjustment component 8, and the camera head of the industrial camera 6 faces the pier body. The adjustment component 8 is used to adjust the position of the industrial camera 6. An auxiliary component 7 is provided in the slide rail 1, and the auxiliary component 7 is used to control the distance between the industrial camera 6 and the pier body. The bottom of the slide rail 1 is fixedly connected to a support frame 11, and a pulley is rotatably connected to the support frame 11. The traction rope between the support rod 3 and the gravity ball 4 is wound and connected to the pulley, and the gravity ball 4 is located directly below the pulley. A group of uniformly spaced serrated structures are provided on one side of the slide rail 2, and a servo motor 12 is fixedly connected to one side of the slide rail 1, and the servo motor 12 is connected to the slide rail 1 through a gear. The plates 2 are meshed and connected, and the length of the slide plate 2 is consistent with the length of the slide rail 1. When the operator needs to perform a flatness test on the pier body, the operator first needs to splice part of the slide rail 1, and then put the power wheel 5 against the pier body, and squeeze the power wheel 5 to shrink the support rod 3, so that the assembled slide rail 1 can be close to the pier body, and then place the remaining assembled slide rails 1 on the other side of the pier body, and apply pressure to connect the slide rails 1 and fix them on the pier body, and then the servo motor 12 starts to rotate. When the servo motor 12 rotates, the slide plate 2 will rotate around the slide rail 1 under the action of the gear, Since the industrial camera 6 is fixed on the slide plate 2, the industrial camera 6 will rotate around the pier body and take pictures of the surface of the pier body during the rotation. After the industrial camera 6 rotates one circle, the servo motor 12 stops rotating and the power wheel 5 starts rotating, so that the slide rail 1 moves on the pier body. When the slide rail 1 moves to the next photo-taking position, the power wheel 5 stops rotating. At this time, the servo motor 12 starts rotating, so that the industrial camera 6 continues to take pictures of other parts of the pier body. After the industrial camera 6 has taken complete pictures of the pier body, the system will automatically collect and process the image data of the pier body surface, and generate a report based on the detection results.

[0043] In this embodiment, if Figure 1 to Figure 2As shown, when the slide rail 1 is squeezed on the pier body, the power wheel 5 will contact the pier body, and at the same time, under the action of the pier body, the support rod 3 will move in the opposite direction. When the support rod 3 moves in the opposite direction, the traction rope will be pulled, and the gravity ball 4 will move upward. When multiple groups of slide rails 1 are connected to each other, the slide rail 1 stops being pressurized, and the gravity ball 4 will move downward. However, since the power wheel 5 is in contact with the surface of the pier body, the support rod 3 cannot move. Therefore, the support rod 3 will squeeze the power wheel 5 tightly on the surface of the pier body under the action of the gravity ball 4. By setting an auxiliary wheel, when the power wheel 5 rolls to make the slide rail 1 rise, the slide rail 1 can be made more stable during the movement.

[0044] As an implementation method in this embodiment, Figures 2 to 6 and Fig. 9 As shown, the auxiliary assembly 7 includes a first oil storage rod 71, a first piston rod 72 is slidably connected in the first oil storage rod 71, the first oil storage rod 71 is connected to two second oil storage rods 76 through hoses, a second piston rod 73 is slidably connected in the second oil storage rod 76, one end of the second piston rod 73 is fixedly connected to an auxiliary rod 74, one end of the auxiliary rod 74 is provided with a group of auxiliary teeth 75 with uniform intervals, the bottom of the auxiliary teeth 75 is fixedly connected to a support plate 751, and one side of the support plate 751 is fixedly connected to the first Spring 753, the other side of the support plate 751 is fixedly connected with a trigger block 752, the bottom of the trigger block 752 is conical, the auxiliary rod 74 is located on one side of the inclined surface of the trigger block 752, the baffles on both sides of the slide rail 1 are provided with a second oil storage rod 76, the baffles on both sides of the slide rail 1 are provided with a group of evenly spaced tooth grooves, the tooth grooves in the slide rail 1 are slidably connected with auxiliary teeth 75, a first spring 753 is provided between the support plate 751 and the baffle, the auxiliary rod 74 is arc-shaped, and the auxiliary rod 74 is slidably connected to the slide rail 1, a group of auxiliary teeth 75 are located on the sliding track of the auxiliary rod 74. When the operator squeezes the power wheel 5 on the pier body, the support rod 3 will move in the opposite direction. When the support rod 3 moves in the opposite direction, since one end of the support rod 3 is fixed to one end of the first piston rod 72, the first piston rod 72 will move synchronously with the support rod 3. When the first piston rod 72 moves, the oil in the two second oil storage rods 76 will be extracted into the first oil storage rod 71. At this time, due to the reduction of oil in the second oil storage rod 76, the second piston rod 73 will move in the second oil storage rod 76 and drive the auxiliary rod 74 to slide in the slide rail 1. When the auxiliary rod 74 slides, the auxiliary rod 74 will squeeze the trigger block 752 at the bottom of the auxiliary tooth 75. Under the action of the bottom inclined surface of the trigger block 752, the auxiliary rod 74 will push the auxiliary tooth 75 out of the tooth groove of the slide rail 1. When the adjustment gear 812 in the adjustment assembly 8 contacts the auxiliary tooth 75, meshing will occur. At this time, the adjustment gear 812 will rotate and drive the industrial camera 6 to move.

[0045] In this embodiment, if Figures 2 to 6 and Fig. 9 As shown, when the diameter of the pier body is thicker, the distance that the support rod 3 moves is longer, and the first piston rod 72 extracts more oil in the second oil storage rod 76. The corresponding second piston rod 73 moves a longer distance, so that the auxiliary rod 74 lifts more auxiliary teeth 75, making the auxiliary tooth 75 group longer. When the auxiliary tooth 75 group is longer, the number of circles rotated when the adjustment gear 812 is engaged with the auxiliary tooth 75 will be more, so that the industrial camera 6 moves a longer distance. Therefore, when the diameter of the pier body is thicker, the industrial camera 6 is farther away from the pier body when taking pictures, so that the industrial camera 6 can take pictures of more parts of the pier body. Conversely, when the diameter of the pier body is smaller, the industrial camera 6 is farther away from the pier body when taking pictures, so that the industrial camera 6 can take pictures of more parts of the pier body. On the contrary, when the diameter of the pier body is smaller, the industrial camera 6 is farther away from the pier body when taking pictures. At the same time, the distance that the industrial camera 6 moves when taking pictures is smaller. At the same time, the two auxiliary tooth groups 75 on the slide rail 1 are respectively located at the two ends of the baffles on both sides. The number of auxiliary teeth 75 that are simultaneously lifted up by the two auxiliary tooth groups 75 is always kept consistent. When the adjustment gear 812 is meshed and connected with the first auxiliary tooth group 75 and rotates, the industrial camera 6 will move away from the pier body. When the adjustment gear 812 is separated from the first auxiliary tooth group 75, the industrial camera 6 starts to take pictures of the pier body. When the adjustment gear 812 is meshed and connected with the second auxiliary tooth group 75 and rotates, the adjustment gear 812 is reversed at this time, and the industrial camera 6 will gradually return to its initial position.

[0046] As an implementation method in this embodiment, Figures 1 to 3 and Figures 7 and 8As shown, the adjustment assembly 8 includes a support column 81, an adjustment plate 82 is fixedly connected to the top of the support column 81, a fixing frame 83 is slidably connected to the adjustment plate 82, a gear shaft 811 is fixedly connected to the top of the support column 81, and both sides of the bottom of the gear shaft 811 are meshed with adjustment gears 812, the gear above the gear shaft 811 is rotatably connected to the adjustment plate 82, a group of uniformly spaced serrated structures are provided on one side of the bottom of the fixing frame 83, one side of the bottom of the fixing frame 83 is meshed with the gear above the gear shaft 811, the two groups of adjustment gears 812 are respectively meshed with the auxiliary teeth 75 on the baffles on both sides of the slide rail 1, the adjustment plate 82 is slidably connected to the top of the slide rail 1, and the top of the fixing frame 83 is fixedly connected with the industrial camera 6, when the support column 81 moves to the position of the auxiliary gear 75 group, the adjustment gear 812 close to the pier body in the support column 81 will mesh with the auxiliary gear 75. The tooth group 75 is meshed and connected, and rotates under the action of the auxiliary tooth group 75. When the adjustment gear 812 rotates, it will drive the middle gear shaft 811 to rotate. When the gear shaft 811 rotates, the gear above the gear shaft 811 drives the fixed frame 83 to move. When the fixed frame 83 moves, it will gradually move the industrial camera 6 away from the pier body. When the adjustment gear 812 is separated from the first group of auxiliary teeth 75 in the slide rail 1, the adjustment gear 812 stops rotating. At this time, the fixed frame 83 stops moving, and the industrial camera 6 takes pictures of the pier body at this time. When the adjustment gear 812 in the support column 81 away from the pier body is meshed and connected with the second group of auxiliary teeth 75 in the slide rail 1, the adjustment gear 812 will reverse, causing the middle gear shaft 811 to reverse, thereby causing the fixed frame 83 to move in the opposite direction, gradually approaching the pier body, and restoring the industrial camera 6 to its initial position.

[0047] A method for detecting pier flatness based on visual technology, the method comprising the following steps:

[0048] S1. According to the conditions at the construction site, multiple sets of slide rails 1 are installed at appropriate positions on the pier body, and corresponding calibration is performed so that the multiple sets of slide rails 1 are located on the same horizontal plane;

[0049] S2, the slide plate 2 rotates under the action of the servo motor 12, so that the industrial camera 6 takes pictures around the pier body;

[0050] S3, start the image acquisition module of the industrial camera 6, and the system automatically collects image data on the surface of the pier body;

[0051] S4. The system automatically processes the collected images, extracts surface features, generates a three-dimensional model or flatness curve, and calculates relevant flatness indicators;

[0052] S5. The system generates a report based on the test results, points out the uneven areas, gives detailed data of the flatness index, and stores and transmits the test data to the construction monitoring center for further analysis and construction quality control.

[0053] According to the working principle of the present invention, when the operator needs to perform a flatness inspection on the pier body, first the operator needs to splice part of the slide rails 1, then put the power wheel 5 against the pier body, and squeeze the power wheel 5 to shrink the support rod 3, so that the assembled slide rails 1 can be close to the pier body, and then the remaining assembled slide rails 1 are placed on the other side of the pier body, and pressure is applied to connect the slide rails 1 and fix them on the pier body, and then the servo motor 12 starts to rotate. When the servo motor 12 rotates, the slide plate 2 will rotate around the slide rail 1 under the action of the gear. Since the industrial camera 6 is fixed on the slide plate 2, the industrial camera 6 will rotate around the pier body at this time, and take pictures of the surface of the pier body during the rotation. When the industrial camera After the machine 6 rotates one circle, the servo motor 12 stops rotating, and the power wheel 5 starts rotating, so that the slide rail 1 moves on the pier body. When the slide rail 1 moves to the next photo position, the power wheel 5 stops rotating. At this time, the servo motor 12 starts rotating, so that the industrial camera 6 continues to take photos of other parts of the pier body. After the industrial camera 6 has completely taken photos of the pier body, the system will automatically collect and process the image data on the surface of the pier body, and generate a report based on the detection results. When the slide rail 1 is squeezed on the pier body, the power wheel 5 will contact the pier body, and at the same time, under the action of the pier body, the support rod 3 will move in the opposite direction. When the support rod 3 moves in the opposite direction, it will pull the traction rope, and the gravity ball 4 will move upward. When multiple groups of slide rails 1 are connected to each other, the slide rails 1 are connected to each other. When the rail 1 stops being pressurized, the gravity ball 4 will move downward, but since the power wheel 5 abuts against the surface of the pier body, the support rod 3 cannot move. Therefore, under the action of the gravity ball 4, the gravity ball 4 will pull the traction rope downward inside the sleeve to tightly squeeze the power wheel 5 against the surface of the pier body. By setting an auxiliary wheel, when the power wheel 5 rolls to make the slide rail 1 rise, the slide rail 1 can be made more stable during the movement. When the operator squeezes the power wheel 5 against the pier body, the support rod 3 will move in the opposite direction. When the support rod 3 moves in the opposite direction, since one end of the support rod 3 is fixed to one end of the first piston rod 72, the first piston rod 72 will move synchronously with the support rod 3. When the first piston rod 72 moves, the two second storage The oil in the oil rod 76 is extracted into the first oil storage rod 71. At this time, due to the reduction of oil in the second oil storage rod 76, the second piston rod 73 will move in the second oil storage rod 76 and drive the auxiliary rod 74 to slide in the slide rail 1. When the auxiliary rod 74 slides, the auxiliary rod 74 will squeeze the trigger block 752 at the bottom of the auxiliary tooth 75. Under the action of the inclined surface at the bottom of the trigger block 752, the auxiliary rod 74 will push the auxiliary tooth 75 out of the tooth groove of the slide rail 1. When the adjustment gear 812 in the adjustment assembly 8 contacts the auxiliary tooth 75, meshing will occur. At this time, the adjustment gear 812 will rotate and drive the industrial camera 6 to move. When the diameter of the pier body is thicker, the distance the support rod 3 moves is longer, and the first piston rod 72 will extract more oil from the second oil storage rod 76.The longer the distance moved by the corresponding second piston rod 73, the more auxiliary teeth 75 are lifted by the auxiliary rod 74, and the longer the auxiliary tooth 75 group is. When the auxiliary tooth 75 group is longer, the number of turns when the adjustment gear 812 and the auxiliary tooth 75 are engaged will be more, so that the industrial camera 6 moves a longer distance. Therefore, when the diameter of the pier body is thicker, the industrial camera 6 is farther away from the pier body when taking pictures, so that the industrial camera 6 can take pictures of more parts of the pier body. On the contrary, when the diameter of the pier body is smaller, the industrial camera 6 takes pictures. The smaller the moving distance is, the two auxiliary gear sets 75 on the slide rail 1 are respectively located at the two ends of the baffles on both sides, and the number of auxiliary gears 75 lifted up by the two auxiliary gear sets 75 is always consistent. When the adjustment gear 812 is meshed and connected with the first auxiliary gear set 75 and rotates, the industrial camera 6 will move away from the pier body. When the adjustment gear 812 is separated from the first auxiliary gear set 75, the industrial camera 6 starts to take pictures of the pier body. When the adjustment gear 812 is meshed and connected with the second auxiliary gear set 75 and rotates, When the adjustment gear 812 is reversed, the industrial camera 6 will gradually return to its initial position. When the support column 81 moves to the position of the auxiliary gear group 75, the adjustment gear 812 near the pier body in the support column 81 will be meshed and connected with the auxiliary gear group 75, and rotate under the action of the auxiliary gear group 75. When the adjustment gear 812 rotates, it will drive the middle gear shaft 811 to rotate. When the gear shaft 811 rotates, the gear above the gear shaft 811 drives the fixing frame 83 to move. When the fixing frame 83 moves, it will bring the industrial camera 6 Gradually away from the pier body, when the adjustment gear 812 separates from the first set of auxiliary teeth 75 in the slide rail 1, the adjustment gear 812 stops rotating, and the fixing frame 83 stops moving. The industrial camera 6 takes pictures of the pier body at this time. When the adjustment gear 812 in the support column 81 away from the pier body is meshed and connected with the second set of auxiliary teeth 75 in the slide rail 1, the adjustment gear 812 will reverse, causing the middle gear shaft 811 to reverse, thereby causing the fixing frame 83 to move in the opposite direction, gradually approaching the pier body, and restoring the industrial camera 6 to its initial position.
