Description

Technical Field

[0001] The present invention relates to the technical field of bridge condition monitoring, and specifically to a bridge condition monitoring device for highway bridge engineering. Background Art

[0002] Highway bridge engineering refers to all works such as the planning, design, construction, maintenance, and repair of structures that cross waters, valleys, and all traffic channels. During or after the construction of a bridge, in order to ensure safety, staff will monitor the condition of the bridge. However, it is difficult to monitor the condition of highway bridges in real time using traditional manual methods, making it difficult to detect small changes in highway bridges in a timely manner. Existing patent documents have made improvements in this regard.

[0003] For example, in Chinese Patent CN218002491U, a bridge condition monitoring device for highway bridge engineering includes a first fixing plate. A second fixing plate is lapped on the right side of the first fixing plate. A connecting plate is fixedly connected to the surface of the second fixing plate, and the connecting plate is fixedly connected to the first fixing plate by bolts. Installation mechanisms are provided on the surfaces of both the second fixing plate and the first fixing plate, and pressure sensors are fixedly connected to the inner walls of both the second fixing plate and the first fixing plate. For this bridge condition monitoring device for highway bridge engineering, when the device is installed on the surface of a pier column and the pier column undergoes displacement, the sliding column is pushed to compress the first spring and squeeze the pressure sensor. When the pier column of the highway bridge undergoes displacement, the goal of facilitating real-time monitoring of the condition of the highway bridge is achieved, facilitating the timely discovery of small changes in the highway bridge, and facilitating targeted maintenance of the highway bridge by staff.

[0004] Although the device in the above document can be installed and closely attached to the pier column, and then the displacement of the pier column is judged by squeezing the sensor, such a setting has obvious disadvantages in actual use, such as: This device uses a fixing plate to install the whole on the surface of the pier column, but the distance between the fixing plate and the pier is constant. Although the sensor can be squeezed when the pier undergoes displacement, under the premise of a limited distance and combined with the overall mass of the pier, the sensor will be directly squeezed and damaged, and it is also easy to damage the whole, affecting normal use; Therefore, a bridge condition monitoring device for highway bridge engineering that can improve detection safety is now designed to solve such defects.

[0015] The present invention provides a bridge condition monitoring device for highway bridge engineering. Compared with the existing technology, it has the following beneficial effects: (1) For the bridge condition monitoring device for highway bridge engineering, by using the support and positioning mechanism and the monitoring and protection mechanism in a combined manner, the settings of these two mechanisms can use the cooperation between the support vertical rods, the first ring cylinder and the second ring cylinder to assemble the first enclosure panel and the second enclosure panel. After assembly, the positioning sleeve plate can be docked with the resilient slider, so that the first clamping plate and the second clamping plate are integrally connected to wrap the pier column, enabling the device to fit closely with the pier column, ensuring the accuracy during subsequent monitoring. The settings of the resilient rod and the sliding sleeve ring can allow the pier column to have greater mobility during displacement, and when the displacement pushes the sliding sleeve ring to move for measurement, it can facilitate the staff to obtain more accurate monitoring data, rather than just knowing the displacement, and at the same time avoid damaging the device, meeting the current usage requirements.

[0016] (2) For the bridge condition monitoring device for highway bridge engineering, by respectively installing the first clamping plate and the second clamping plate on one side of the first enclosure panel and the second enclosure panel, and installing the slidable resilient slider and the positioning sleeve plate by using the U-shaped guide groove and the limiting sliding opening, the settings of these structures can adjust the distance between the first clamping plate and the second clamping plate, enabling the first enclosure panel and the second enclosure panel to be used on the surfaces of pier columns with different widths, thereby improving the applicability of the device.

[0017] (3) For the bridge condition monitoring device for highway bridge engineering, by respectively installing the first ring cylinder and the second ring cylinder for cooperating with each other on both sides of the first enclosure panel and the second enclosure panel, and using the support vertical rods, the cross slots and the threaded pressing plates, the settings of these structures can, after the first enclosure panel and the second enclosure panel are docked, utilize the docking of the cross slots and the cross guide bars to form a rectangular shape and quickly fixedly connect the first enclosure panel and the second enclosure panel. It does not require the staff to use bolt assemblies for cumbersome fixed installation, and the quick fixed installation also facilitates the subsequent adjustment of the resilient slider and the positioning sleeve plate, providing convenience for the staff.

[0018] (4) The bridge condition monitoring device for this highway bridge project is used by installing a number of protective fences between two support vertical rods and matching with a protective cover plate. The setting of these structures can, after the installation of the first enclosing plate and the second enclosing plate, enable the protective fences and the protective cover plate to protect the internal components, avoiding the occurrence of the situation that the sliding sleeve ring is offset due to the influence of the outside world during daily use, thus ensuring the safety and stability of the equipment during use.
