Description

Technical Field

[0001] This utility model relates to the field of bridge welding technology, specifically a deformation monitoring device for bridge welding. Background Technology

[0002] Welding is a crucial step in bridge construction and maintenance. The steel structure of a bridge must be welded to form a stable whole, bearing enormous loads and complex stresses. The high temperatures generated during welding can cause uneven heating of the weldment, leading to deformation. This deformation not only affects the dimensional accuracy of the bridge structure, causing assembly deviations between components, but more seriously, it negatively impacts the overall mechanical properties and stability of the bridge, reducing its load-bearing capacity, creating safety hazards, and potentially leading to structural failure due to cumulative deformation over long-term use, resulting in serious safety accidents. Currently, traditional methods for monitoring bridge welding deformation rely on manual measurement using simple measuring tools. This method is inefficient, unable to meet the monitoring needs of large-scale bridge welding projects, and is greatly affected by human factors, resulting in limited measurement accuracy and errors, making it difficult to accurately capture minute deformations. While strain gauge monitoring can obtain strain data to some extent, it suffers from poor real-time performance, failing to provide timely feedback on dynamic deformation during welding. Furthermore, the installation and wiring of strain gauges are cumbersome, inconvenient to operate in the complex bridge structural environment, and easily affected by environmental factors, leading to inaccurate data.

[0003] Therefore, the present invention provides a deformation monitoring device for bridge welding to solve the above problems. Utility Model Content

Although the method of using strain gauges for monitoring can obtain strain data to a certain extent, it has the problem of poor real-time performance and cannot provide timely feedback on the dynamic deformation during the welding process.

In view of this, the present disclosure proposes a deformation monitoring device for bridge welding. By flexibly changing the angle and position between the first, second, and third connecting arms through a connecting bolt assembly, the monitoring sensor assembly is accurately aligned with the bridge welding part to be monitored. The laser displacement sensor emits a laser beam to monitor the linear displacement of the welding part in real time, while the tilt sensor is used to detect the angle change of the weldment during the welding process. The collected data is transmitted to the LCD display controller in real time, and the operator can intuitively view the deformation data of the bridge welding part on the screen of the LCD display controller. This realizes multi-dimensional and all-round monitoring of the bridge welding part, more comprehensively reflecting the real situation of bridge welding deformation, providing more comprehensive and richer data for the mechanical performance analysis and safety assessment of the bridge structure, helping to improve the overall stability and safety of the bridge, and reducing later maintenance costs and safety risks.

The column 4 is vertically fixed above the mounting base plate 1. The adjustable mounting bracket assembly 6 is fixedly installed on one side of the column 4. The monitoring sensor assembly 7 is fixedly installed at the front end of the adjustable mounting bracket assembly 6. The liquid crystal display controller 8 is fixedly installed on one side of the column 4 and electrically connected to the liquid crystal display controller 8.

[0023] The monitoring device is installed at a suitable location near the bridge welding area using the mounting base 1. Based on the specific location of the bridge welding area and monitoring requirements, the adjustable mounting bracket assembly 6 is adjusted. The angles and positions between the first connecting arm 602, the second connecting arm 603, and the third connecting arm 604 are flexibly changed via the connecting bolt assembly 608, accurately aligning the monitoring sensor assembly 7 with the bridge welding area to be monitored. The laser displacement sensor emits a laser beam to monitor the linear displacement of the welding area in real time, while the tilt sensor detects angular changes in the weldment during the welding process. The collected data is transmitted in real time to the LCD display controller 8, allowing operators to visually view the deformation data of the bridge welding area on the LCD display controller 8's screen. The LCD display controller 8 uses a 7-inch touchscreen to display displacement, tilt angle data, and historical curves in real time, and supports user-defined alarm thresholds and data export functions.

[0024] In this embodiment, the connecting bolt assembly 608 can employ any existing structure or device for controlling angle adjustment, such as existing bolts, washers, and lock nuts.

During adjustment, first loosen the bolts of the connecting bolt assembly 608, adjust each connecting arm to the target position, align the monitoring sensor assembly with the welding area, and then tighten the bolts to secure it. The monitoring sensor assembly 7 communicates with the LCD display controller via RS485 or CAN bus, using the Modbus protocol for data transmission.

During installation, they are fixed with screws and calibrated to zero using a calibrator. The tilt sensor has a measurement range of ±180°, an accuracy of ±0.01°, and a data acquisition frequency of 100Hz.

[0025] like Figure 1 As shown, a solar panel 10 is fixedly installed on the top of the column 4, and the solar panel 10 is electrically connected to the battery 13. The solar panel 10 is tilted above the column 4.

[0026] Solar panels 10 can convert solar energy into electrical energy and store it in batteries 13, providing continuous power support for the device and improving the device's energy efficiency and range.

[0027] like Figure 1 As shown, a data transmitter 9 is fixedly installed above the liquid crystal display controller 8, and the data transmitter 9 is electrically connected to the liquid crystal display controller 8.

[0028] The monitoring data is remotely transmitted to the monitoring center via data transmitter 9.

The wireless communication network utilizes high-speed communication technologies such as 5G or Wi-Fi to ensure the timeliness and stability of data transmission, facilitating real-time monitoring of the bridge welding deformation by management personnel, enabling timely detection of potential safety hazards and the implementation of corresponding measures. The data transmitter 9 uploads data to the cloud server via MQTT or TCP / IP protocols; the monitoring center receives and displays real-time data through a web interface.

Reinforcing ribs 15 are installed inside the column 4. There are four reinforcing ribs 15, and the four reinforcing ribs 15 are located at the four corners of the column 4. The reinforcing ribs 15 and the column 4 are integrated.

[0030] The foam 14 attached to the outside of the battery 13 can play a protective and cushioning role, preventing the battery 13 from being damaged by collisions during transportation or use. The reinforcing rib 15 increases the structural strength of the column 4, effectively preventing the column 4 from deforming and breaking due to external impact, and improving the stability of the monitoring device.

[0031] The battery 13 is a lithium-ion battery with a capacity of 10000mAh and a voltage of 12V. A solar charging controller is installed inside the column 4, providing overcharge and over-discharge protection to ensure safe charging and discharging of the battery.

A rubber pad 2 is installed under the mounting base plate 1, and the rubber pad 2 is fitted to the mounting base plate 1.

[0033] The mounting base plate 1 is securely installed near the bridge welding area by installing anchor bolts 3. The elastic washer 11 between the anchor bolts 3 and the mounting base plate 1 can buffer and reduce shock, reducing the impact of external vibration on the device. The rubber pad 2 under the mounting base plate 1 further enhances the stability and anti-slip properties of the device installation.

[0034] The anchor bolts used are M12 chemical anchor bolts. During installation, holes are first drilled on the bridge surface, anchoring adhesive is injected, and then the anchor bolts are inserted and tightened. The elastic washers are made of rubber to reduce vibration transmission.

[0035] When using this bridge welding deformation monitoring device, the mounting base plate 1 is first securely installed near the bridge welding area using anchor bolts 3. The elastic washer 11 between the anchor bolts 3 and the mounting base plate 1 acts as a buffer and shock absorber, reducing the impact of external vibrations on the device. The rubber pad 2 under the mounting base plate 1 further enhances the stability and anti-slip properties of the device installation. Based on the specific location of the bridge welding area and monitoring requirements, the adjustable mounting frame assembly 6 is adjusted. The angle and position between the first connecting arm 602, the second connecting arm 603, and the third connecting arm 604 are flexibly changed using the connecting bolt assembly 608, accurately aligning the monitoring sensor assembly 7 with the bridge welding area to be monitored. The laser displacement sensor can accurately measure the displacement changes of the bridge welding area, while the tilt sensor can acquire the angle changes of that area in real time. The collected data is transmitted in real time to the LCD display controller 8, allowing operators to visually view the deformation data of the bridge welding area on the screen of the LCD display controller 8. The monitoring data is remotely transmitted to the monitoring center via the data transmitter 9, enabling management personnel to monitor the dynamic situation of bridge welding deformation in real time, promptly identify potential safety hazards, and take corresponding measures. The battery 13 serves as a backup power source for the device. The externally attached foam 14 provides protection and cushioning, preventing the battery 13 from being damaged by collisions during transportation or use.
