Bridge deflection monitoring device

Abstract

The application discloses a bridge dynamic deflection monitoring device and belongs to the technical field of bridge monitoring equipment. The device comprises a monitoring box, an assembling plate, a connecting clamping plate movably installed in the assembling plate, a connecting column for slidingly connecting the monitoring box, and a limiting bottom plate connected to the bottom end of the connecting column. The third spring acts on the mounting frame to mesh the connecting gear with the rack, thereby ensuring the stability of the connection and controlling the rotation of the adjusting ring to adjust the height of the bearing plate, so that the receiver cooperates with the transmitter. When the limiting bottom plate shakes and deviates, the rack will make the connecting gear rotate, so that the driving belt wheel drives the driven belt wheel to rotate through the synchronous belt wheel, and the transmitter rotates on the surface of the mounting disc to detect the displacement of the bridge. The integrated controller can be used to transmit data to the terminal equipment, so that detailed information of the bridge can be obtained for the maintenance of the bridge.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge monitoring equipment, in particular to a bridge dynamic deflection monitoring device. BACKGROUND

[0002] Deflection refers to the bending value of a building or its components in the horizontal direction or vertical direction. The beam part of the bridge will produce downward bending in the middle, and the high-rise building will produce lateral bending. Deflection observation is to measure and analyze the degree of bending through certain technology, instrument or method.
