[0004] Preferably, the limit block matches the limit groove provided inside the sliding block, and the limit block is threadedly connected to the sliding block, and five limit blocks are provided.

[0005] Preferably, a solenoid is fixedly installed inside the slide cylinder, a spring is arranged outside the solenoid, and the spring is electrically connected to the control panel.

[0006] Preferably, a connecting slider is fixedly connected to the bottom of the spring, and an iron sheet is fixedly installed on the top of the connecting slider.

A rangefinder, a wireless digital bridge vibration detector, a concrete crack comprehensive detector, an industrial endoscope, and a bridge flatness detector are connected to the bottom of the five connecting columns from left to right in sequence.

[0008] Preferably, the rangefinder is used to measure the external structural dimensions of the bridge. The rangefinder usually uses laser or ultrasonic technology to measure the distance. The laser rangefinder calculates the distance by emitting a laser beam to the target and measuring the return time, while the ultrasonic rangefinder calculates the distance by emitting an ultrasonic wave and detecting its return time.

[0009] Preferably, the wireless digital transmission bridge vibration detector is used for daily inspection and monitoring of bridge equipment. The wireless digital transmission bridge vibration detector can dynamically monitor the status of the bridge. During inspection, three probes are evenly arranged on the piers or beam spans of the bridge to collect bridge vibration data when the train is running.

[0010] Preferably, the comprehensive concrete crack detector can accurately detect the width and depth of cracks on the bridge surface. Bridge surface cracks are an important item in bridge inspection. Using traditional measurement methods is time-consuming and labor-intensive, and there are certain errors. The comprehensive concrete crack detector can automatically identify cracks, and interpret, display, record, and store them with an accuracy of up to .mm, which greatly improves the speed and accuracy of the comprehensive "physical examination" of the bridge.

The portable industrial endoscope is small in size and highly flexible. The front-end lens can be extended to the inside of the bridge for inspection, and the image can be transmitted in real time. The bridge flatness detector consists of three parts: a sensor, a measurement system, and a data processing system.

[0012] Preferably, a method for using an automatic bridge crack detection device comprises the following steps: S1. Install the support column above the testing instrument to ensure the stability of the testing instrument; S2. The height of the support column is adjusted by hydraulic rods to adapt to bridges of different heights and spans; S3.

Use a comprehensive concrete crack detector to detect the location and depth of concrete cracks; S8. Use an industrial endoscope to inspect the internal structure of the bridge; S9. Use a bridge flatness detector to detect the flatness of the bridge surface; S10. View and record all test data on the control panel for analysis and processing; S11. After completing the inspection, disassemble and organize the equipment for next use.

[0013] Compared with the prior art, the present invention provides an automatic bridge crack detection device, which has the following beneficial effects: 1. The distance meter is an important component of the automatic detection equipment for bridge cracks. It is used to measure the length, width, height and other parameters of the bridge. By emitting a laser beam to the surface of the bridge and measuring the time for the reflection back, the size of the bridge is calculated. The distance meter has the characteristics of high precision and fast measurement, and can provide accurate bridge size data, providing a basis for subsequent crack detection.

[0014] 2. The bridge crack automatic detection equipment, wireless digital bridge vibration detector is used to detect the vibration of the bridge. Acceleration sensors are arranged on the bridge to monitor the vibration signal of the bridge in real time and convert it into an electrical signal. Then, the electrical signal is transmitted to the remote monitoring center through wireless transmission technology. At the monitoring center, the received signal is processed and analyzed to extract the vibration characteristics of the bridge, such as frequency, amplitude, etc. These characteristics can be used to evaluate the structural health of the bridge and predict potential crack risks.

[0015] 3. The bridge crack automatic detection equipment and the concrete crack comprehensive detector are devices used to detect the location and depth of cracks in concrete structures. The equipment transmits ultrasonic waves to the concrete structure and receives the reflected signals. By analyzing the propagation time and waveform changes of the reflected waves, the location and depth of the cracks can be determined. At the same time, combined with image processing technology, the detection results can be presented in the form of images for easy observation and analysis.

[0016] 4. The automatic detection equipment for bridge cracks, the industrial endoscope is used to detect the internal structure of the bridge. The industrial endoscope consists of a slender probe and a display. The probe can be inserted into the internal structure of the bridge. The image transmitted back by the probe can be used to observe the damage, corrosion and cracks inside the bridge. The industrial endoscope has the characteristics of high resolution and high sensitivity, and can provide clear internal structure images to help discover potential hidden dangers.

[0017] 5. The bridge crack automatic detection equipment and bridge flatness detector are used to detect the flatness of the bridge surface. The equipment sets up multiple sensors on the bridge surface to monitor the height changes of the bridge surface in real time. Through data processing technology, these height data are analyzed and processed to extract the flatness parameters of the bridge, such as the maximum height difference, the average height difference, etc. These parameters can be used to evaluate the driving comfort and safety of the bridge, as well as predict potential risks such as cracks.
