Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring equipment technology, and in particular to a bridge bearing appearance inspection device. Background Technology

[0002] As a crucial component of bridge structures, bearings play a vital role in connecting the superstructure and substructure. Damage or abnormalities in bearings directly affect the stress distribution of the entire structure, leading to deformation or even collapse, while also accelerating structural aging and degradation. Regular surface inspections of bearings can promptly detect issues such as wear, corrosion, and aging, allowing for appropriate maintenance and repair measures to ensure structural safety, extend service life, and reduce overall maintenance costs.

[0003] However, some bearing locations are concealed or difficult to access, especially those on large bridges and elevated structures, making it challenging for inspectors to reach these locations for detailed inspection. Furthermore, working at heights poses inherent safety risks, increasing the complexity and danger of the inspection process. In addition, resource and time constraints may limit the frequency and coverage of bearing appearance inspections. Especially with limited personnel and funding, comprehensive and regular inspections of all bearings are difficult to conduct, potentially allowing problems to worsen undetected. Simultaneously, different regions and organizations may have varying standards and methods for bearing appearance inspection, lacking unified specifications and standards. This inconsistency affects the comparability and reliability of inspection results, increasing the difficulty of management and maintenance. Therefore, developing an automated bearing appearance inspection device is essential.

[0004] Patent CN202320747830.5 discloses a real-time monitoring system for bridge bearings that combines inspection and routine checks. This system includes an intelligent bearing unit, a bridge inspection crawling robot, and a periodically inspecting drone. The intelligent bearing unit is used for long-term monitoring; the bridge inspection crawling robot is used for routine checks; and the periodically inspecting drone is used for periodic inspections. This invention utilizes a drone equipped with a camera platform to photograph the appearance of bridge bearings and obtains surface evaluation data through image processing and analysis. While other methods utilize drones to photograph bridge images and obtain surface cracks in bearings, their four-legged bionic structure is complex, motor control is difficult, the vacuum suction cups pose a risk of falling in humid environments, and drone inspections suffer from significant positioning errors of the GPS positioning module at the bottom of the bridge, the gimbal camera's shooting angle is obstructed by the rotor, and the coverage of blind spots at the bottom of the bearings is low. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, such as high safety risks, incomplete coverage, and data lag, and to provide a bridge bearing appearance inspection device. Through high-efficiency and low-cost automated inspection, it can flexibly adapt to complex scenarios, perform high-precision detection and data management, and extend the service life of bridges.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] This utility model provides a bridge bearing appearance inspection device, comprising:

[0008] The traveling track assembly includes: a traveling track, a track support, a track height adjusting nut, and a fixing nut unit. The track support is connected to the bridge pier via the track height adjusting nut and fixed by the fixing nut unit. Furthermore, the traveling track is circular or rounded-corner rectangular in shape to adapt to the external contour of the support. Traditional tracks cannot adapt to supports of different sizes, and the uneven surface of the bridge pier makes installation difficult. Through the height adjusting nut and contour-following track design, a single device can adapt to multiple types of supports.

[0009] The transmission assembly includes a side wheel, a wheel support structure, a stepper motor, and a toothed belt. The side wheel is fixed to the wheel support structure by bearings. The stepper motor drives the toothed belt through gears, causing the transmission assembly to move along the travel track. Traditional chain drives have backlash, which causes image acquisition position offset. The toothed belt drive eliminates backlash, and combined with the micro-step control of the stepper motor, ensures image stitching accuracy.

[0010] Appearance image acquisition component, including a camera, for acquiring appearance images of the support;

[0011] The development board is used to control the operation of the stepper motor and the camera to capture images and upload data; it enables real-time upload functionality.

[0012] The power supply components, including a lithium battery, a wireless charging module, and a step-down module, are used to power the stepper motor, development board, and camera.

[0013] The transmission component, the appearance image acquisition component, the development board, and the power supply component are all mounted on the walking track component.

[0014] Through the precise mechanical transmission of the toothed belt in the transmission component, the precise optical acquisition of the appearance image acquisition component, and the real-time edge computing of the development board, the bridge inspection achieves high installation adaptability, high inspection accuracy, real-time data monitoring, and high monitoring efficiency.

[0015] Furthermore, the fixing nut unit includes an upper fixing nut and a lower fixing nut. The lower fixing nut is used for auxiliary limiting of the track height adjusting nut, and the upper fixing nut is used for final fixing of the track support.

[0016] Furthermore, the toothed belt of the transmission assembly is arranged along the outer side of the travel track, and the stepper motor meshes with the toothed belt through gears.

[0017] Furthermore, the development board has a pre-installed automatic inspection program that controls the rotation direction and number of steps of the stepper motor to enable the device to move forward, backward, and stop at a fixed point on the track.

[0018] Furthermore, the camera acquires images at a set position via a trigger signal from the development board.

[0019] Furthermore, the wireless charging receiver of the power supply component is a wireless charging module, which is located on the device body. The wireless charging transmitter is set in the initial position. The wireless charging transmitter is a wireless charging coil, which is used to receive energy transmitted from the external transmitter to realize automatic charging after the inspection task.

[0020] Furthermore, the step-down module is used to adjust the output voltage of the lithium battery to the operating voltage of the development board and the camera.

[0021] Furthermore, the walking track is rigidly connected to the bridge pier via track supports, and the track height adjustment nut allows for fine-tuning of the track height.

[0022] Furthermore, the development board integrates a wireless communication module to upload the collected image data to the cloud or terminal device in real time.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] (1) Automated inspection replaces high-risk operations. By controlling the stepper motor and camera through the program, unmanned inspection of the support surface can be achieved, avoiding the risks of manual high-altitude operations, reducing inspection costs and the probability of safety accidents.

[0025] (2) Flexible adaptation to complex scenarios. The walking track can be designed as a circle or a rounded rectangle to adapt to different support shapes; the track height is adjustable, compatible with various bridge pier structures, and covers hidden locations that are difficult for traditional equipment to reach.

[0026] (3) High-precision detection and data management. Stepper motors are used in conjunction with toothed belt drives to ensure precise movement of the device and avoid displacement deviation; the development board triggers fixed-point shooting to ensure the integrity of image acquisition and uploads data to the cloud in real time for remote analysis of defects.
