Embodiment Construction
[0019] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 As shown, a bridge omnidirectional displacement detection device according to the present invention includes a rubber pad clamping device fixed on the object to be detected, one end of which is connected with an omnidirectional displacement conversion device fixed on the pier 20, and the The omnidirectional displacement conversion device sends an alarm signal and the serial number of the rubber pad 19 to the terminal through the control box.
[0021] See figure 2 , which shows a top view of the rubber pad clamping device of the detection device of the present invention. The rubber pad clamping device includes an elastic caliper 1, which is fixed on the rubber pad 19 in a half-wrapped manner in the direction of the longitudinal section, and keeps a certain safety distance from the bridge plate 18, and...

The invention discloses a bridge omnidirectional displacement detection device and detection method, and the device comprises a rubber pad clamping device, an omnidirectional displacement conversion device and a control box, wherein the rubber pad clamping device is fixed on an object to be detected, one end of the rubber pad clamping device is connected with the omnidirectional displacement conversion device fixed on a pier, and the omnidirectional displacement conversion device sends an alarm signal and the number of a rubber pad to a terminal through the control box. According to the invention, the detection method based on the detection device comprises the following steps of detecting the omnidirectional displacement of the rubber pad between a bridge plate and a bridge pier, and whenthe displacement of any one of three axes of the omnidirectional displacement is greater than a preset offset, sending an alarm signal to the terminal and marking the number of the rubber pad. The bridge omnidirectional displacement detection device and detection method can be applied to detecting the omnidirectional displacement or deformation of a bridge support and the health condition of a bridge, can greatly save the maintenance cost of the bridge, can avoid the major loss caused by shutting down the traffic by frequent overhaul, and can reduce the loss caused by bridge accidents to themaximum extent.
Description
technical field [0001] The invention relates to a bridge health state detection device and a detection method, in particular to a bridge omnidirectional displacement detection device and a detection method. Background technique [0002] At this stage, most of the bridge inspection engineering practice still adopts the traditional detection method, that is, using some conventional equipment to collect a certain amount of data on the spot for the material defect of the bridge structure, and then process and analyze the data to obtain the bridge’s Damage status. [0003] As the owner of the bridge management department, after the bridge has certain structural variation or working condition variation, it puts forward the tasks and requirements of bridge inspection to the relevant departments and units in response to these variations; Factors such as funds are often only tested on the content of the test proposed by the owner, which has caused great limitations. The owner invit...
