Description

Technical Field

[0001] This invention relates to the field of building inspection equipment technology, specifically to a rust prevention inspection device for steel structure buildings. Background Technology

[0002] Steel structure buildings are widely used in factories, bridges, high-rise buildings, and other fields due to their advantages such as high strength, short construction period, and high space utilization. However, steel structures are exposed to the air for a long time and are susceptible to corrosion from rain, moisture, and corrosive gases. Corrosion weakens the strength of the steel structure and causes safety hazards. Therefore, regular rust prevention inspections of steel structures are a key aspect of ensuring building safety.

[0003] Traditional steel structure rust inspection relies heavily on manual operation. Inspectors need to use ladders, scaffolding, and other tools to approach the steel structure surface and judge the rust condition by visual observation or handheld testing instruments. This is not only labor-intensive and inefficient, but also poses safety risks due to working at heights. Furthermore, manual inspection is easily affected by subjective factors, making it difficult to accurately identify subtle rust traces, leading to missed or false detections. With the development of testing technology, some semi-automatic testing equipment has appeared on the market, but it still has significant drawbacks. For example, a steel structure rust detection device disclosed in patent number CN202221567890.3, although equipped with detection sensors, lacks a cleaning pretreatment structure. Dust and impurities on the steel structure surface can easily interfere with the test results, reducing the accuracy of the test. Moreover, the equipment needs to be manually pushed and moved, making it difficult to stably hold steel structures of different sizes. It is also prone to displacement during the testing process, affecting the continuity of the test.

[0004] Existing steel structure rust inspection equipment generally suffers from the following problems: 1. Lack of integrated cleaning function: Dust and loose rust adhering to the steel structure surface can obscure rusted areas, leading to misjudgments by the detection sensors. Manual cleaning is required beforehand, increasing additional procedures and time costs. 2. Poor clamping and movement performance: It is difficult to adapt to steel structures with different cross-sectional dimensions. Clamping too loosely can cause the equipment to shift, while clamping too tightly can damage the steel structure surface. Furthermore, movement requires manual assistance and cannot move autonomously along the extension direction of the steel structure, resulting in low detection efficiency. 3. Inconvenient transmission and storage of detection data: The wires between the sensors and the controller are prone to tangling and knotting, affecting equipment operation. Moreover, it lacks real-time data analysis capabilities, requiring post-processing of exported data, making it impossible to promptly determine the degree of rust and formulate remedial measures. Summary of the Invention

[0005] The purpose of this invention is to provide a rust prevention inspection device for steel structure buildings to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a housing, a cleaning and installation assembly disposed on one side inside the housing, a clamping and adjusting assembly disposed at both ends of the housing, a winding and fixing assembly disposed at the bottom and one end of the housing, and a controller connected to the housing via a wire; The cleaning installation assembly includes multiple mounting slots opened on one side of the housing, a first motor detachably connected to the mounting slots, a drive shaft connected to the output end of the first motor, a connecting block connected to one end of the drive shaft, a circular plate detachably connected to one end of the connecting block, and a brush detachably connected to the surface of the circular plate. The first motor drives the drive shaft to rotate the circular plate and the brush. The clamping and adjusting assembly includes inner grooves at both ends of the housing, a mounting shell detachably connected to the inside of the inner groove, multiple rubber sleeves detachably connected to the inside of the mounting shell, multiple spring columns installed inside the rubber sleeves, a clamping block with a mounting plate mounted on its surface, a mounting port at one end of the mounting plate, and a movable wheel connected to the surface of the clamping block. One end of the rubber sleeve is installed in conjunction with the mounting port, and the clamping block clamps the steel structure. The winding and fixing assembly includes movable slots on both sides of the housing, a second motor installed inside the movable slots, a movable wheel connected to the output end of the second motor, a hydraulic rod connected to one end of the housing, a movable shell detachably connected to one end of the hydraulic rod via a fixing block, a vertical plate fixedly connected to the surface of the controller, a fixing plate connected to the vertical plate, and a winding roller connected to the surface of the fixing plate. The movable shell and the housing cooperate to form an integral structure, and the winding roller is used to wind up the wires connecting the housing and the controller. A laser detector is mounted on the housing. The laser detector is electrically connected to a controller via wires. The controller is used to receive and process the detection data from the laser detector.

[0007] Preferably, the plurality of mounting slots are evenly distributed along the length of the housing, and each mounting slot is equipped with a corresponding first motor. The plurality of first motors start synchronously to drive the corresponding brush to rotate.

[0008] Preferably, the circular plate and the connecting block are bolted together, the brush is evenly distributed along the circumference of the circular plate, and the bristle length of the brush is adapted to the surface cleaning requirements of the steel structure.

[0009] Preferably, the housing is U-shaped, and the two inner grooves are respectively opened on the inner sides of the two ends of the U-shaped structure of the housing, and each inner groove is equipped with a corresponding mounting shell.

[0010] Preferably, the plurality of spring posts are evenly distributed along the length of the rubber sleeve, and the spring posts have elasticity and can adjust the clamping force of the clamping block by their own extension and contraction.

[0011] Preferably, there are multiple movable wheels, which are symmetrically distributed along the length of the clamping block. The movable wheels are in contact with the surface of the steel structure and can roll along the surface of the steel structure as the device moves.

[0012] Preferably, the movable slot is detachably connected to the second motor, and the two second motors are respectively installed inside the movable slots on both sides of the housing. The second motors synchronously drive the corresponding moving wheels to rotate. Preferably, the hydraulic rod and the housing are rotatably connected, and the hydraulic rod can extend and retract to move the movable housing closer to or away from the housing. The shape of the movable housing is adapted to the shape of both ends of the housing.

[0013] Preferably, the winding roller and the fixed plate are rotatably connected, and the winding roller can wind up or release the wire by rotating. The laser detector is installed on the side of the housing near the steel structure and is used to scan the surface corrosion of the steel structure.

[0014] A method for using a cable tray with intelligent safety detection function includes the following steps: Step 1: Equipment Assembly and Debugging: The first motor is detachably installed in the mounting slot on one side of the housing. The drive shaft, connecting block, and circular plate are connected sequentially. A brush is installed on the surface of the circular plate. The mounting shell is detachably installed in the inner slots at both ends of the housing. Rubber sleeves and spring columns are installed inside the mounting shell. The mounting plate is connected to the rubber sleeve through the mounting port, ensuring the movable wheels on the clamping block surface are securely installed. One end of the hydraulic rod is connected to the housing, and the other end is used to install the movable shell through the fixing block. The length of the hydraulic rod is adjusted to form a complete clamping structure between the movable shell and the housing. The second motor is installed in the movable slots on both sides of the housing. The second motor is connected to the movable wheels. The housing is connected to the controller via wires. A fixing plate and a take-up roller are installed on the vertical plate of the controller. The wires are wound around the take-up roller. Step 2, Clamping and Position Adjustment: Based on the cross-sectional dimensions of the steel structure, activate the hydraulic rod. The extension and retraction of the hydraulic rod moves the movable shell, which, in conjunction with the clamping blocks at both ends of the shell, clamps the steel structure. During clamping, the spring columns inside the rubber sleeve adapt to the dimensions of the steel structure through elastic extension and retraction, preventing damage to the steel structure due to excessive clamping or displacement of the equipment due to excessive clamping. Adjust the angle of the laser detector to align it with the surface of the steel structure to be inspected. Adjust the wire length using the take-up roller to ensure that the wire between the controller and the shell is not tangled. Step 3, Cleaning Pre-treatment: Start the first motor of the cleaning installation component through the controller. The first motor drives the transmission shaft to rotate, and the transmission shaft drives the connecting block, circular plate and brush to rotate synchronously. Push the device or start the moving wheel to make the rotating brush move in contact with the steel structure surface to clean the dust, floating rust and other impurities on the steel structure surface, and remove interference for subsequent rust prevention inspection. Step 4, Rust Prevention Detection and Data Transmission: Start the second motor, which drives the moving wheels to rotate, causing the entire device to move slowly along the extension direction of the steel structure. During the movement, the laser detector continuously scans the surface of the steel structure and transmits the detected rust data (such as rust area and rust depth) to the controller via wires. The controller receives and processes the data in real time, determines the degree of rust on the steel structure through its built-in program, and displays the detection results on the screen. Step 5, Detection Path Adjustment and Supplementary Inspection: If the controller displays abnormal rust data or incomplete detection in a certain area, turn off the second motor to stop the device from moving; adjust the length of the hydraulic rod to fine-tune the clamping position of the device, or manually push the device to adjust the detection angle through the movable wheels, and repeat the scan and supplementary inspection of the abnormal area to ensure the accuracy of the detection data; Step Six: Equipment Recovery and Maintenance: After the test is completed, turn off the laser detector, the first motor and the second motor; start the hydraulic rod to retract, so that the movable shell is separated from the steel structure and the clamping block is released; rotate the winding roller to wind up the wire to prevent the wire from falling off; clean the impurities remaining on the brush surface, check whether the clamping block, movable wheel and moving wheel are worn, and replace any damaged parts in time. Store the device in a dry and ventilated place.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. The cleaning and installation components of this device can automatically clean the steel structure surface before inspection. Multiple primary motors drive the brushes to rotate synchronously, effectively removing dust, rust, and other interfering impurities, avoiding misjudgments caused by incomplete or missed areas in traditional manual cleaning. The brushes are detachably connected to the connecting blocks via circular plates, allowing for the replacement of brushes with different hardnesses according to the steel structure surface material, ensuring cleaning effectiveness while avoiding damage to the steel structure surface. After cleaning, there is no need to transfer the equipment; rust detection is performed directly through a laser detector, achieving a continuous "cleaning-detection" operation. Compared to the traditional step-by-step "manual cleaning + equipment detection" mode, this reduces process time by more than 50%, while significantly improving the accuracy of rust detection and avoiding missed or false detections caused by impurities obstructing the view.

[0016] 2. The clamping adjustment assembly adopts a combination design of spring columns and rubber sleeves. The elastic extension and retraction of the spring columns can automatically adapt to steel structures with different cross-sectional dimensions (such as I-beams, angle steel, and channel steel), eliminating the need for frequent manual adjustments to clamping parameters. The rubber sleeves can buffer the clamping force, preventing damage to the coating on the steel structure surface. The movable wheels on the clamping block surface and the moving wheels at the bottom of the housing form a dual movement assistance. The movable wheels can reduce friction between the device and the steel structure, allowing the device to move smoothly along the steel structure surface. The moving wheels are driven by a second motor, enabling the device to move autonomously without manual pushing. This is especially suitable for high-altitude or long-distance steel structure inspection, reducing the labor intensity and safety risks for inspection personnel. In addition, the hydraulic rod drives the movable housing to form an adjustable clamping space, further expanding the device's adaptability to different specifications of steel structures and improving the equipment's versatility.

[0017] 3. The winding roller in the winding and fixing assembly can automatically wind up or release the wire between the housing and the controller, avoiding operational obstruction caused by wire tangling and knotting in traditional testing equipment. Especially when the device moves long distances along the steel structure, it can keep the wire neat and orderly, reducing testing interruptions caused by wire problems. The controller receives the detection data from the laser detector in real time through the wire. The built-in program can quickly analyze parameters such as rust area and depth, instantly determine the rust level of the steel structure and display the results, without the need for secondary processing of exported data. The inspectors can formulate supplementary inspection or repair plans on the spot based on the real-time results, shortening the inspection cycle. At the same time, the detachable connection design between the wire and the controller facilitates the disassembly, transportation and storage of the equipment, making it particularly suitable for testing operations in complex environments at construction sites.

[0023] Specifically, the housing 1 is in the shape of a "U" and the two inner grooves 301 are respectively opened on the inner sides of the two ends of the "U" shaped structure of the housing 1. Each inner groove 301 has a corresponding mounting shell 302 installed inside it.

[0024] Specifically, multiple spring posts 304 are evenly distributed along the length of the rubber sleeve 303. The spring posts 304 have elastic extensibility and can adjust the clamping force of the clamping block 305 by their own extension and retraction.

[0025] Specifically, there are multiple movable wheels 308, which are symmetrically distributed along the length of the clamping block 305. The movable wheels 308 are in contact with the surface of the steel structure and can roll along the surface of the steel structure as the device moves.

[0026] Specifically, the movable slot 401 is detachably connected to the second motor 402. The two second motors 402 are respectively installed inside the movable slots 401 on both sides of the housing 1. The second motors 402 synchronously drive the corresponding moving wheels 403 to rotate. Specifically, the hydraulic rod 404 is rotatably connected to the housing 1. The hydraulic rod 404 can extend and retract to move the movable shell 406 closer to or further away from the housing 1. The shape of the movable shell 406 is adapted to the shape of both ends of the housing 1.

[0027] Specifically, the take-up roller 410 is rotatably connected to the fixed plate 409. The take-up roller 410 can take up or release the wire 408 by rotating. The laser detector 411 is installed on the side of the housing 1 near the steel structure and is used to scan the surface corrosion of the steel structure.

[0028] A method for using a rust prevention inspection device for steel structure buildings includes the following steps: Step 1: Equipment Assembly and Debugging: The first motor 202 is detachably installed in the mounting groove 201 on one side of the housing 1. The drive shaft 203, connecting block 204, and circular plate 205 are connected sequentially. A brush 206 is installed on the surface of the circular plate 205. The mounting shell 302 is detachably installed in the inner grooves 301 at both ends of the housing 1. A rubber sleeve 303 and a spring post 304 are installed inside the mounting shell 302. The mounting plate 306 is connected to the rubber sleeve 303 through the mounting port 307, ensuring the movable wheel 308 on the surface of the clamping block 305 is securely installed. Connect one end of the hydraulic rod 404 to the housing 1, and install the movable housing 406 at the other end through the fixing block 405. Adjust the length of the hydraulic rod 404 so that the movable housing 406 and the housing 1 form a complete clamping structure. Install the second motor 402 in the movable slots 401 on both sides of the housing 1. Connect the second motor 402 to the moving wheel 403. Connect the housing 1 to the controller 412 through the wire 408. Install the fixing plate 409 and the winding roller 410 on the vertical plate 407 of the controller 412. Wind the wire 408 around the winding roller 410. Step 2, Clamping and Position Adjustment: Based on the cross-sectional dimensions of the steel structure, activate the hydraulic rod 404. The extension and retraction of the hydraulic rod 404 drives the movable shell 406 to move, cooperating with the clamping blocks 305 at both ends of the shell 1 to clamp the steel structure. During the clamping process, the spring column 304 inside the rubber sleeve 303 adapts to the dimensions of the steel structure through elastic extension and retraction, avoiding damage to the steel structure due to excessive clamping or displacement of the equipment due to excessive clamping. Adjust the angle of the laser detector 411 to align it with the surface of the steel structure to be inspected. Adjust the length of the wire 408 through the take-up roller 410 to ensure that the wire 408 between the controller 412 and the shell 1 is not tangled. Step 3, Cleaning Pre-treatment: The first motor 202 of the cleaning installation component 2 is started by the controller 412. The first motor 202 drives the transmission shaft 203 to rotate, and the transmission shaft 203 drives the connecting block 204, the circular plate 205 and the brush 206 to rotate synchronously. The pushing device or the moving wheel 403 is started to make the rotating brush 206 move in contact with the surface of the steel structure to clean the dust, floating rust and other impurities on the surface of the steel structure, and remove interference for subsequent rust prevention inspection. Step 4, Rust Prevention Detection and Data Transmission: Start the second motor 402, which drives the moving wheel 403 to rotate, causing the entire device to move slowly along the extension direction of the steel structure. During the movement, the laser detector 411 continuously scans the surface of the steel structure and transmits the detected rust data (such as rust area and rust depth) to the controller 412 through the wire 408. The controller 412 receives and processes the data in real time, determines the degree of rust on the steel structure through the built-in program, and displays the detection results on the display screen. Step 5, Detection Path Adjustment and Supplementary Inspection: If the controller 412 displays abnormal rust data or incomplete detection in a certain area, turn off the second motor 402 to stop the device from moving; adjust the length of the hydraulic rod 404 to fine-tune the clamping position of the device, or manually push the device through the movable wheel 308 to adjust the detection angle, and repeat the scan and supplementary inspection of the abnormal area to ensure the accuracy of the detection data; Step Six: Equipment Recovery and Maintenance: After the inspection is completed, turn off the laser detector 411, the first motor 202 and the second motor 402; start the hydraulic rod 404 to retract, so that the movable shell 406 separates from the steel structure, and loosen the clamping block 305; rotate the winding roller 410 to wind up the wire 408 to prevent the wire 408 from falling off; clean the impurities remaining on the surface of the brush 206, check whether the clamping block 305, the movable wheel 308 and the moving wheel 403 are worn, and replace any damaged parts in time. Store the device in a dry and ventilated place.

[0029] Working Principle: The cleaning and installation component 2 of this device automatically cleans the steel structure surface before inspection. Multiple first motors 202 drive the brushes 206 to rotate synchronously, efficiently removing dust, rust, and other interfering impurities, avoiding misjudgments caused by incomplete or missed areas in traditional manual cleaning. The brushes 206 are detachably connected to the connecting block 204 via a circular plate 205, allowing for the replacement of brushes 206 with different hardnesses depending on the steel structure surface material, ensuring cleaning effectiveness while avoiding damage to the steel structure surface. After cleaning, there is no need to transfer the equipment; rust prevention inspection is directly performed via the laser detector 411, achieving a continuous "cleaning-inspection" operation. Compared to the traditional step-by-step "manual cleaning + equipment inspection" mode, this reduces workload by 50%. The above process time significantly improves the accuracy of rust detection, avoiding missed or false detections caused by impurities. The clamping adjustment component 3 adopts a combination design of spring column 304 and rubber sleeve 303. The elastic extension and retraction of spring column 304 can automatically adapt to steel structures of different cross-sectional dimensions (such as I-beams, angle steel, and channel steel), eliminating the need for frequent manual adjustment of clamping parameters. The rubber sleeve 303 can buffer the clamping force and avoid damage to the surface coating of the steel structure. The movable wheel 308 on the surface of clamping block 305 and the moving wheel 403 at the bottom of housing 1 form a dual movement assistance. The movable wheel 308 can reduce the friction between the device and the steel structure, allowing the device to move smoothly along the surface of the steel structure. The moving wheel 403 is driven by the second motor 402, enabling the device to move autonomously without manual pushing. It is especially suitable for high-altitude or long-distance steel structure inspection, reducing the labor intensity and safety risks of inspection personnel. In addition, the hydraulic rod 404 drives the movable housing 406 to form an adjustable clamping space. This further expands the device's adaptability to different specifications of steel structures and enhances its versatility. The winding roller 410 in the winding and fixing assembly 4 can automatically wind up or release the wire 408 between the housing 1 and the controller 412, avoiding operational obstruction caused by the wire 408 getting tangled in traditional testing equipment. Especially when the device moves a long distance along the steel structure, it can keep the wire 408 neat and orderly, reducing testing interruptions caused by problems with the wire 408. The controller 412 receives the detection data from the laser detector 411 in real time through the wire 408. The built-in program can quickly analyze parameters such as rust area and depth, instantly determine the rust level of the steel structure and display the results, without the need for secondary processing of exported data.

10. A method of using a steel structure building rust prevention inspection device according to claim 9, characterized in that: Includes the following steps: Step 1, Equipment Assembly and Debugging: The first motor (202) is detachably installed in the mounting groove (201) on one side of the housing (1), and the drive shaft (203), connecting block (204), and round plate (205) are connected in sequence. A brush (206) is installed on the surface of the round plate (205). The mounting shell (302) is detachably installed in the inner grooves (301) at both ends of the housing (1). A rubber sleeve (303) and a spring column (304) are installed inside the mounting shell (302). The mounting plate (306) is connected to the rubber sleeve (303) through the mounting port (307) to ensure that the movable wheel (308) on the surface of the clamping block (305) is installed firmly. One end of the hydraulic rod (404) is connected to the housing (1), and the other end is mounted on the movable housing (406) through the fixing block (405). The length of the hydraulic rod (404) is adjusted so that the movable housing (406) and the housing (1) form a complete clamping structure. The second motor (402) is installed in the movable slots (401) on both sides of the housing (1). The second motor (402) is connected to the moving wheel (403). The housing (1) is connected to the controller (412) through the wire (408). The fixing plate (409) and the take-up roller (410) are installed on the vertical plate (407) of the controller (412). The wire (408) is wound around the take-up roller (410). Step 2, clamping and positioning adjustment: According to the cross-sectional dimensions of the steel structure, start the hydraulic rod (404), and move the movable shell (406) by extending and retracting the hydraulic rod (404), which works with the clamping blocks (305) at both ends of the shell (1) to clamp the steel structure; during the clamping process, the spring column (304) inside the rubber sleeve (303) adapts to the dimensions of the steel structure by elastic extension and retraction, avoiding damage to the steel structure by clamping too tightly or displacement of the equipment by clamping too loosely; adjust the angle of the laser detector (411) to align it with the surface of the steel structure to be inspected, and adjust the length of the wire (408) by the take-up roller (410) to ensure that the wire (408) between the controller (412) and the shell (1) is not tangled; Step 3, Cleaning Pre-treatment: Start the first motor (202) of the cleaning installation component (2) through the controller (412). The first motor (202) drives the transmission shaft (203) to rotate. The transmission shaft (203) drives the connecting block (204), the circular plate (205) and the brush (206) to rotate synchronously. Push the device or start the moving wheel (403) so that the rotating brush (206) moves in contact with the steel structure surface to clean the dust, floating rust and other impurities on the steel structure surface, and remove interference for subsequent rust prevention inspection. Step 4, Rust Prevention Detection and Data Transmission: Start the second motor (402), which drives the moving wheel (403) to rotate, causing the entire device to move slowly along the extension direction of the steel structure. During the movement, the laser detector (411) continuously scans the surface of the steel structure and transmits the detected rust data (such as rust area and rust depth) to the controller (412) through the wire (408). The controller (412) receives and processes the data in real time, judges the degree of rust on the steel structure through the built-in program, and displays the detection results on the display screen. Step 5, Detection path adjustment and supplementary inspection: If the controller (412) displays abnormal rust data or incomplete detection in a certain area, turn off the second motor (402) to stop the device from moving; adjust the length of the hydraulic rod (404) to fine-tune the device clamping position, or manually push the device through the movable wheel (308) to adjust the detection angle, and repeat the scan and supplementary inspection of the abnormal area to ensure the accuracy of the detection data; Step 6, Equipment Recovery and Maintenance: After the test is completed, turn off the laser detector (411), the first motor (202) and the second motor (402); start the hydraulic rod (404) to retract, so that the movable shell (406) is separated from the steel structure, and loosen the clamp (305); rotate the winding roller (410) to wind up the wire (408) to prevent the wire (408) from falling off; clean the impurities remaining on the surface of the brush (206), check whether the clamp (305), movable wheel (308) and moving wheel (403) are worn, and replace any damaged parts in time. Store the device in a dry and ventilated place.
