Description

Technical Field

[0001] The invention relates to the field of bridge detection, and in particular to a bridge crack measuring device. Background Art

[0002] A bridge refers to a building built for roads to cross natural or artificial obstacles. It is built on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Concrete has the characteristics of thermal deformation and cold shrinkage. When the external ambient temperature or internal ambient temperature changes, the concrete will deform. If the deformation is restricted, ground stress will be generated. When the ground stress exceeds the tensile strength of the concrete, temperature cracks are likely to occur. The foundation settlement or horizontal displacement of the bridge foundation generates additional stress in the structure, which exceeds the tensile strength of the concrete structure and causes the structure to crack. The bridge crack measuring device can accurately detect the width and depth of cracks on the bridge surface, greatly improving the speed and accuracy of the comprehensive "physical examination" of the bridge. The existing bridge crack measuring device usually uses manual and imaging technology to perform measurement operations during the measurement process. Different types of bridges have different crack detection methods. When encountering cracks in arch bridges and beam bridges, the mobile push measurement structure will produce measurement errors due to the influence of the gap, making it difficult to fit and adjust, reducing the overall measurement effect; Therefore, we propose a bridge crack measuring device to solve the above problems.

[0015] Beneficial effects of the present invention:

[0016] 1. Different from the previous measurement operation usually performed by manual and imaging technology, the central pressure-bearing component is used as the main body to perform the middle load-bearing support operation. When encountering cracks in arch bridges and beam bridges, a suitable angle is selected, and the second driver drives the guide rod to pass through the connecting frame to drive the guide frame to swing and adjust to a suitable pre-start and stop angle to complete the initial swing adjustment. At the same time, for stability, the first slider drives the sliding sleeve clamp to slide along the slide rail, which can gradually approach the crack on the bridge to perform fitting and docking operations, complete the middle support stability, and quickly expand the load-bearing situation. Then the driving motor drives the rotating shaft to pass through the protective cover to drive the guide sliding sleeve to swing and adjust for secondary angle adjustment. At the same time, the second slider drives the extension arm to slide along the slide slot to drive the flip-type crack measurement component to complete the extension state. Finally, the control motor drives the steering rod to drive the main rod to gradually measure the bridge cracks. With the synchronous bending operation of the extension, the telescopic cylinder drives the telescopic push rod to pass through the connecting frame to drive the support plate to adjust, and the adsorption module performs strong magnetic adsorption to maintain a certain angle with the wall to form a stable support, which is convenient for secondary expansion on the top, thereby improving the overall fitting control performance.

[0017] 2. As the main rod is turned and adjusted, its camera can observe the shape and length of the shallow surface of the crack in turn. The circumferential sound wave interactive module on the synchronous cross frame can gradually transmit the sound wave state and detect the state of the deep layer of the crack. The information is fed back to the control panel in turn to form interactive detection performance. According to the installation requirements, the adjusting bolt drives the steering swing frame and the cross bar to swing and adjust to form various steering shapes. The plug-in holes are used to adapt and install different measurement auxiliary structures, thereby enhancing the crack measurement processing performance.

[0018] 3. When performing ground cleaning operations, as the crawler module moves and reaches a suitable position, the first driver drives the turntable to drive the two sets of central pressure plates to turn toward each other and reach a suitable turning angle, so that it can better drive the cleaning and diversion components to perform dust removal. The third driver drives the rotating rod to drive the connecting rod and the bending rod to reach a suitable reciprocating angle, and the cracks are gradually cleaned by the brush strip, which is convenient for the extended parallel crack measurement component to observe in sequence and avoid interference. The solution is pre-filled into the solution tank through the filling pipe. As the brush strip cleans, it is sprayed out through the ejector with an ejection port, which can not only perform cleaning operations but also increase crack recognition. The vibration module drives the brush strip to reduce dust clogging the ejection port and form a cleaning performance.

[0019] 4. When performing ground measurement operations, the reduction motor drives the drive rod to drive the M-type bending frame to adjust, and the fourth driver drives the steering ring to drive the M-type bending frame nodes to expand rapidly to form a stretched state. According to the direction of the crack, the expansion and contraction operations are carried out in sequence to form an operation of tracking the direction of the crack. The image module is used for timely observation and identification, and the recorded information is fed back to the control panel and antenna module for timely recording of information.

At the same time, for stability, the first slider 306 drives the sliding sleeve clamp 305 to slide along the sliding rail 304, which can gradually approach the cracks on the bridge and perform fitting and docking operations to complete the middle support stability and quickly expand the load-bearing situation. Then the driving motor 309 drives the rotating shaft 308 to pass through the protective cover 307 to drive the guide sliding sleeve 310 to swing and adjust. A secondary angle adjustment is performed, and at the same time, the second slider 402 drives the extension arm 401 to slide along the slide groove 311, driving the flip-type crack measuring component 4 to complete the extension state. Finally, the motor 404 is controlled to drive the steering rod to drive the main rod 405 to gradually measure the bridge cracks. With the synchronous bending operation of the extension, the telescopic cylinder 316 drives the telescopic push rod 313 to pass through the connecting frame 312 to drive the support plate 314 to adjust, and the adsorption module performs strong magnetic adsorption to maintain a certain angle with the wall, forming a stable support, which is convenient for secondary expansion on the top, thereby improving the overall fitting and control performance.

[0040] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
