Description

Technical Field

[0002] Plate rubber bearings are important components that connect the upper and lower structures of bridges. They mainly play the following four roles: transferring loads; meeting the angular deformation of the upper structure; buffering the impact of vehicles passing through; and providing shock absorption and isolation. During the operation of the bridge structure, it is necessary to detect the vertical compression residual deformation of the plate rubber bearings used on the bridge.

[0003] Announcement No. CN220304472U discloses a plate-type rubber bearing deformation detection device, which uses the displacement of the detection rod detected by the displacement sensor during the extrusion process as the deformation detection data. The displacement sensor has high accuracy, but the detection principle of the displacement sensor is to convert the physical displacement into an electrical signal for recording, so the error between the actual deformation and the reference physical displacement must be low enough to make the final detection data accurate enough; the test plate-type rubber bearing is placed on the detection platform, and then the deformation displacement detection component is placed in the initial state, the initial state is to cut off the power to the first electromagnet and energize the second electromagnet, so that the second magnet on the outside of the detection rod is in a fixed state, the first magnet and the detection rod are in a sliding state, so that the applicability movement is completed during the downward pressure of the extrusion plate, but the patent still has the following problems in actual use:

[0004] The device adjusts the optimal initial position of the detection rod by energizing two sets of electromagnets at different time periods. During the adjusted extrusion process, the displacement sensor can complete high-precision displacement detection. However, the device does not have a limit function. During the detection process, the plate rubber bearing needs to withstand the pressure from the extrusion plate and deform in the process. If it is not limited, it may be offset due to unbalanced force during the extrusion process or insufficient friction between the bearing and the detection platform.
