Abstract

The invention relates to the technical field of bridge detection, and discloses a bridge displacement detection device and method, and the device comprises a telescopic plate, one side of the telescopic plate is provided with a measuring structure, and the measuring structure comprises a measuring block, an indicating block, a moving groove, a dial gauge, a pointer, a moving block, a connecting block, a rolling block, a joining block, a bottom plate, a sliding block, and a lead screw. When a rotating force is applied to the lead screw, the lead screw can control the sliding block to horizontally and longitudinally move along the open groove, and when the sliding block moves, the rolling block is stressed and then controls the moving block to horizontally and longitudinally move along the moving groove. The measuring structure measures the distance between the bridge pier and one side of the bridge by taking the bridge pier as the midpoint through the screw rod and the measuring block, then the screw rod is rotated to control the measuring block to move to increase the detection distance, so that the measuring result is more accurate, and the offset distance is obtained through the data of the pointer on the scale marks.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a bridge displacement detection device and a detection method. Background technique [0002] Bridge application testing means to detect the whole or main components of the bridge structure, understand the working state and bearing capacity of the bridge structure and its components, verify the design calculation theory of the bridge structure, check the construction quality and find problems in the application, etc. There are mainly strain, displacement and vibration tests. Strain test. According to the linear relationship between stress and strain within a certain range, the stress is calculated by measuring the strain or other values ​​are calculated accordingly. For steel bridges, it can be used to understand the internal force, secondary stress transfer, stress concentration state, bridge deck stress distribution and its interaction with the main girder, as well as...
