Description

Technical Field

[0001] This invention relates to the field of intelligent inspection robot technology, specifically to an intelligent concrete inspection robot and method for smart construction sites. Background Technology

[0002] Intelligent inspection robots are intelligent devices that integrate sensors, autonomous navigation, and AI analysis functions. They can automatically complete target inspection and output data. In smart construction sites, they are the core tool for concrete quality control. They can replace manual labor in high-risk areas such as high altitudes and tunnels. The core of the inspection is to automatically collect key data such as concrete cracks and internal voids through sensors such as vision and ultrasound, avoiding the safety risks and efficiency shortcomings of manual inspection. At the same time, the inspection data can be transmitted to the smart construction site platform in real time and combined with AI algorithms to quickly identify and classify defects, thereby significantly shortening the time from inspection to results and reducing human data analysis errors.

[0003] Existing intelligent inspection robots often fail to operate properly when inspecting concrete surfaces with laitance due to the interference of laitance. For example, laitance on the concrete surface can hinder effective contact between the sensor and the concrete substrate, causing disordered reflected signals during ultrasonic sensor detection and leading to misjudgments of internal voids. At the same time, laitance on the concrete surface can also interfere with the image acquisition of visual sensors, causing AI models to be unable to clearly identify cracks on the concrete surface, resulting in missed crack detection or misidentification of laitance accumulation as cracks, affecting the accuracy of defect judgment. However, existing intelligent inspection robots do not have a laitance removal mechanism. To avoid these problems, workers need to assess the laitance before inspection, which increases the time and cost and affects inspection efficiency.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figures 1-5 and Figures 7-9As shown, the present invention provides a technical solution: a smart construction site concrete intelligent inspection robot, including an inspection mechanism 1. The inspection mechanism 1 includes a tracked chassis 101. A placement box 102 is installed on the top rotating end of the tracked chassis 101. A driver 103 and a navigation module 104 are installed on the bottom inner wall of the placement box 102. Cover plates 105 are installed at both ends of the placement box 102. Multiple rubber sleeves 106 are movably inserted through the top inner wall of the placement box 102. Multiple hexagonal posts 107 and a fixing frame 110 are fixed to the bottom inner wall of the placement box 102. A control board 108 and an antenna 109 are installed between the tops of a group of hexagonal posts 107. The control board 108 is located inside the placement box 102. A battery 111 is installed inside the fixing frame 110. A robotic arm 112 is installed on the top of the placement box 102. Two... The connecting blocks 113 are symmetrical. Each connecting block 113 has a perforated plate 114 installed at one end. Each perforated plate 114 is connected to a corresponding connecting block 113 with a stabilizing plate 115. Each perforated plate 114 has a movable plate 116 movably sleeved inside. Each perforated plate 114 has an electric push rod 117 installed on its surface. Each electric push rod 117 has a connecting plate 118 installed at its telescopic end. Each connecting plate 118 is fixed to the surface of the corresponding movable plate 116. One movable plate 116 has a vision sensor 119 and a tilt sensor 120 installed on its surface. Another movable plate 116 has a fixed base 121 fixed on its surface. An ultrasonic sensor 122 is pressed and fixed inside the fixed base 121. One cover plate 105 has a switch 123 installed on its surface, and the control end of the switch 123 moves through the surface of the cover plate 105.

[0037] In this embodiment, when the intelligent inspection robot receives an inspection command, the control board 108 first activates the tracked chassis 101 via the driver 103, navigation module 104, and battery 111, causing the activated tracked chassis 101 to move the entire intelligent inspection robot. When the intelligent inspection robot moves to the designated position, the tracked chassis 101 will pause. Then, the control board 108 will again activate the robotic arm 112 and turn on the tilt sensor 120 via the driver 103 and battery 111. At this time, the front end of the activated robotic arm 112 will move, driving the components connected to and mounted on it to move together. When the acquisition end of the vision sensor 119 illuminates the required acquisition position on the concrete surface, and the vision sensor... When sensor 119 is adjusted to a horizontal position by tilt sensor 120, control board 108 pauses robotic arm 112 and then activates electric actuator 117 on another perforated plate 114. This activated electric actuator 117, in cooperation with the connecting plate 118, the corresponding perforated plate 114, and the mounting base 121, drives ultrasonic sensor 122 to retract. When ultrasonic sensor 122 reaches a point where it cannot move further, the activated electric actuator 117 is paused, and then vision sensor 119 is activated. Vision sensor 119 then acquires an image of the concrete surface and transmits it to control board 108. Upon receiving the image data, control board 108 utilizes its integrated... The processing module first performs preliminary invalid data screening, and then uses its integrated AI analysis module to analyze and process the data to determine whether there are cracks in the detected area. At the same time, the control board 108 also wirelessly transmits the collected image data and analysis results to the smart construction site platform through the antenna 109. When it is necessary to perform ultrasonic detection on the detected location, the vision sensor 119 is first turned off. Then, the control board 108, one of the perforated plates 114, the connecting plate 118, the driver 103, and the electric push rod 117 are used to move the vision sensor 119 back to a position where it cannot move. Then, the front end of the robotic arm 112 is rotated 180 degrees to swap the positions of the vision sensor 119 and the ultrasonic sensor 122. Then, the ultrasonic sensor is turned on again. 122 is reset to its original position. After resetting, the ultrasonic sensor 122 is moved horizontally to contact the concrete surface through the robotic arm 112 and tilt sensor 120. Then, the ultrasonic sensor 122 is turned on to collect data. The collected data is then transmitted to the control board 108. After receiving the data, the control board 108 will first perform preliminary invalid data screening and then perform analysis to determine whether there are voids in the detected area. At the same time, the control board 108 will also wirelessly transmit the collected data and analysis results to the smart construction site platform through the antenna 109. When the intelligent detection robot completes the concrete surface detection operation, all components are reset first, and then the previously activated components are turned off.

[0038] Example 2: According to Figures 1-9 As shown, the detection mechanism 1 is equipped with a removal mechanism 2, which is used to clean the solidified laitance on the surface of the concrete block. The removal mechanism 2 includes a motor 201, a perforated rod 205, an image acquisition sensor 212, and a cylindrical groove 214. The output end of the motor 201 is connected to a cylindrical rod 202, and a gear 203 is fixedly sleeved on the outer surface of the cylindrical rod 202. A set of sliding grooves 204 are preset on the inner wall of the perforated rod 205. A grooved rod 206 is movably sleeved inside the perforated rod 205. A slider 207 is slidably connected between the inside of the perforated rod 205 and the inside of the set of sliding grooves 204. Connecting rods 208 are rotatably connected inside the grooves on both sides of the slider 207. An internally rotating connection includes a set of symmetrical rotating plates 209. Each rotating plate 209 has a strip-shaped grinding block 210 adhered to its surface. A circular grinding block 211 is adhered to one end of a perforated rod 205. A grooved rod 206, a slider 207, a connecting rod 208, and the perforated rod 205 control the retraction and extension of the rotating plates 209. The teeth of the gear 203 mesh with the grooves of the grooved rod 206. One end of each of the two connecting rods 208 is rotatably connected to a groove at one end of each of the two rotating plates 209. A counterweight 213 is provided around the perforated rod 205. The detection mechanism 1 includes a tracked chassis 101. A placement box 102 is mounted on the rotating top end of the tracked chassis 101. A driver 103 and a navigation module 104 are installed on the bottom inner wall of the placement box 102. Multiple hexagonal pillars 107 and a fixing frame 110 are fixed on the bottom inner wall of the placement box 102. A control board 108 and an antenna 109 are installed between the tops of a group of hexagonal pillars 107. A robotic arm 112 is installed on the top of the placement box 102. The cylindrical groove 214 is pre-set at the front end of the robotic arm 112. The grooved rod 206 is movably sleeved inside the cylindrical groove 214. Two symmetrical connecting blocks 113 are installed at the front end of the robotic arm 112. A motor 201 is installed on the surface of one of the connecting blocks 113. One end of the rod 202 movably passes through the surface of one of the connecting blocks 113. Meanwhile, a gear 203 is slidably embedded on the surface of another connecting block 113, a gear 203 is located between the two connecting blocks 113, a perforated rod 205 is fixed between the two connecting blocks 113, a counterweight 213 is mounted on the surface of another connecting block 113, a perforated plate 114 is mounted on one end of each connecting block 113, an image acquisition sensor 212 is mounted on the surface of one of the perforated plates 114, a stabilizing plate 115 is mounted between each perforated plate 114 and the corresponding connecting block 113, a movable plate 116 is movably sleeved inside each perforated plate 114, and a vision sensor 119 and a tilt sensor 120 are mounted on the surface of one of the movable plates 116.

[0039] In this embodiment, when there is laitance in the area of ​​the concrete surface to be detected and needs to be treated, the intelligent detection robot is first moved to the detection position, then the image acquisition sensor 212 is turned on, and the circular grinding block 211 is moved to the horizontal position of the concrete surface detection area through the tilt sensor 120. Then, the circular grinding block 211 is moved towards the concrete surface detection area, and at the same time, the front end of the robotic arm 112 is rotated. At this time, the rotating front end of the robotic arm 112 will rotate the circular grinding block 211 through two connecting blocks 113 and the perforated rod 205. When the circular grinding block 211 contacts the laitance and continues to move towards it, the rotating and moving circular grinding block 211 will clean it. When there is a lot of laitance in the area of ​​the concrete surface to be detected, the control board 108 and the driver 103 are used to start... The motor 201 is started. When started, the motor 201 drives the round rod 202 to rotate via two connecting blocks 113. The rotating round rod 202 drives the gear 203 to rotate. At the same time, the rotating gear 203 uses the perforated rod 205 to move the grooved rod 206 out of the cylindrical groove 214. Then, the moving grooved rod 206 uses a set of sliding grooves 204 and the perforated rod 205 to move the slider 207 along the trajectory. Then, the moving slider 207 uses two connecting rods 208 and the perforated rod 205 to unfold the two rotating plates 209. The unfolded two rotating plates 209 drive the connected strip grinding block 210 to rotate. When the two rotating plates 209 are fully unfolded, the motor 201 is paused. Then, the above operation steps are repeated to treat the concrete surface with laitance. Then, the test is performed.

[0040] The overall effect and working principle of the mechanism are as follows: When in use, the entire intelligent inspection robot is started by using switch 123 to enter the initial stage. Then, the entire intelligent inspection robot is wirelessly connected to the smart construction site platform by antenna 109. Then, the smart construction site platform sends the inspection position command to the intelligent inspection robot. After receiving the command, the intelligent inspection robot will start to move.

[0041] First, the control board 108 activates the tracked chassis 101 via the driver 103, navigation module 104, and battery 111, causing the activated tracked chassis 101 to move the entire intelligent inspection robot. When the intelligent inspection robot reaches the designated position, the tracked chassis 101 will pause. Then, the control board 108 will again activate the robotic arm 112 and activate the tilt sensor 120 via the driver 103 and battery 111. At this time, the front end of the activated robotic arm 112 will move, driving the components connected to and mounted on it to move together. When the acquisition end of the vision sensor 119 illuminates the desired acquisition position on the concrete surface, and the vision sensor 119 is adjusted to a horizontal state by the tilt sensor 120, the control board 108 will pause the robotic arm 112, and then activate the electric actuator on another perforated plate 114. When the electric actuator 117 is activated, it will drive the ultrasonic sensor 122 to move back in cooperation with the connecting plate 118, the corresponding perforated plate 114 and the fixed base 121. When the ultrasonic sensor 122 can no longer move, the electric actuator 117 is paused. Then the vision sensor 119 is activated. The vision sensor 119 will collect images of the concrete surface and transmit the collected images to the control board 108. After receiving the image data, the control board 108 will first use its integrated processing module to perform preliminary invalid data screening, and then use its integrated AI analysis module to perform analysis and processing to determine whether there are cracks in the detected area. At the same time, the control board 108 will also wirelessly transmit the collected image data and analysis results to the smart construction site platform through the antenna 109.

[0042] When ultrasonic testing is required at the detected location, first turn off the vision sensor 119. Then, using the control board 108, one of the perforated plates 114, the connecting plate 118, the driver 103, and the electric actuator 117, move the vision sensor 119 back to its immovable position. Next, rotate the front end of the robotic arm 112 180 degrees to swap the positions of the vision sensor 119 and the ultrasonic sensor 122. Then, reset the ultrasonic sensor 122 to its original position. After resetting, use the robotic arm 112 and the tilt sensor 120 to level the ultrasonic sensor 122. The robot moves to contact the concrete surface with its detection end, then turns on the ultrasonic sensor 122 to collect data. The collected data is then transmitted to the control board 108. After receiving the data, the control board 108 first performs preliminary invalid data screening, and then performs analysis to determine whether there are voids in the detected area. At the same time, the control board 108 also wirelessly transmits the collected data and analysis results to the smart construction site platform through the antenna 109. When the intelligent detection robot completes the concrete surface detection operation, it first resets all components and then shuts down the previously activated components.

[0043] When there is laitance on the concrete surface and it needs to be treated, first move the intelligent inspection robot to the inspection position, then turn on the image acquisition sensor 212, and use the tilt sensor 120 to move the circular grinding block 211 to the horizontal position of the concrete surface inspection area. Then move the circular grinding block 211 towards the concrete surface inspection area, while the front end of the robotic arm 112 rotates. The rotating front end of the robotic arm 112 will rotate the circular grinding block 211 through two connecting blocks 113 and the perforated rod 205. When the circular grinding block 211 contacts the laitance and continues to move towards it, the rotating and moving circular grinding block 211 will clean it. When the laitance on the concrete surface has been cleaned, repeat the above operation steps for inspection.

[0044] When there is a lot of laitance in the area of ​​the concrete surface being tested (initially in a closed state, such as...) Figure 5 When the motor 201 is started using the control board 108 and the driver 103, the motor 201 will rotate using the two connecting blocks 113. The rotating rod 202 will then rotate the gear 203. Simultaneously, the rotating gear 203 will use the perforated rod 205 to move the grooved rod 206 out of the cylindrical groove 214. The moving grooved rod 206 will then use a set of sliding grooves 204 and the perforated rod 205 to move the slider 207 along the trajectory. The moving slider 207 will then use the two connecting rods 208 and the perforated rod 205 to unfold the two rotating plates 209. The unfolded rotating plates 209 will then drive the connected strip grinding block 210 to rotate. When the two rotating plates 209 are fully unfolded, the motor 201 will be paused. The above operation steps will then be repeated to perform laitance treatment on the concrete surface, followed by inspection.
