Description

Technical Field

[0001] The utility model relates to the technical field related to bridge safety monitoring, and specifically is a novel bridge structure safety monitoring and early warning device. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and seas to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that cross mountain streams, poor geology, or meet other traffic needs to make passage more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. When building a bridge, safety monitoring and early warning devices are required to conduct real-time safety monitoring and processing of the bridge structure.

[0003] There are many types of existing bridge safety monitoring and early warning devices, but there are still certain shortcomings in their use. Most of the current monitoring devices directly use brackets to install vibration sensors at the monitoring position of the bridge structure. Therefore, the subsequent disassembly and assembly of the vibration sensors is time-consuming and labor-intensive, which increases the difficulty of maintenance. In addition, under long-term vibration conditions, the brackets are very likely to loosen and fall off from the bridge structure, which is a safety problem. In order to overcome the above-mentioned defects, reference can be made to the bridge structure monitoring device based on a vibration sensor disclosed in the prior art (application number and publication date of Chinese patent). The monitoring device is provided with an early warning mechanism. When the concave retaining frame and the bridge body become loose, the detection plate is pushed outward and separated from the press switch under the push of the positioning spring. Therefore, the press switch outputs an alarm signal to the alarm, thereby realizing a real-time early warning of the connection status of the concave retaining frame and the bridge body.

[0004] Although the above-mentioned existing technology can solve the purpose of real-time warning, there are still other problems in the process of operation. When performing real-time monitoring and processing, the positioning spring and the support ear are coordinated to realize early warning processing, but the coordination of the expansion bolt will affect the elasticity of the positioning spring, which will affect its accuracy during the monitoring process.

[0005] Therefore, we proposed a new type of bridge structure safety monitoring and early warning device that can solve the above problems well. Utility Model Content
