Description
Technical Field
[0001] The utility model relates to the technical field of deformation detection, in particular to a highway bridge support deformation detection device. Background Art
[0002] Bridge bearings are important structural components installed between the bridge superstructure and the piers. They not only transmit force, but also have the ability to transmit and transform displacement, allowing the bridge beams and slabs to move and vibrate within a controllable range. Therefore, they are very important in bridge design.
[0003] The occurrence of shear deformation is due to the horizontal force of the bridge (bridge expansion and contraction, etc.). The "Highway Bridge Plate Rubber Bearings" stipulates that the shear angle of the bearing should not be greater than 35°, and the shear deformation direction of the rubber bearing is toward the lower part of the bridge, so it is necessary to measure the shear angle of the rubber bearing.
[0004] When existing bridge bearings are used to detect deformation, they are usually observed manually or by inserting measuring instruments into the gaps of bridge piers to complete the deformation detection of bridge bearings. However, since the main part of the bridge bearing that undergoes deformation is the rubber bearing in the bridge bearing, and the deformation of rubber is difficult to directly observe with the naked eye, when it undergoes visible deformation, the bridge has already encountered serious problems. When using measuring instruments for detection, single data cannot form comparative data for judging the deflection angle, and single data deviation will occur. Utility Model Content
[0005] In view of the above problems, the purpose of the utility model is to provide a highway bridge bearing deformation detection device to solve the problem that a single data cannot form comparative data for judging the deflection angle, and thus a single data deviation will occur. The deformation degree of the bridge bearing is judged according to the deflection angle of the angle scale, and two angle scales are used together as a group to form comparative data for judging the deflection angle, thereby avoiding the deviation of the single data.
[0006] To achieve the above objectives, the utility model adopts the following technical solution: a highway bridge bearing deformation detection device, comprising a bracket assembly, an adjustment assembly, and a detection assembly, the bracket assembly comprising a bracket base, the adjustment assembly comprising an adjustment rod, the detection assembly comprising a gear and a positioning plate, the top of the bracket base is connected to a rubber bearing, the end of the rubber bearing away from the bracket base is connected to a bracket top plate, both ends of the adjustment rod are symmetrically connected to rod teeth, the top of the bracket base is connected to a mounting tube, both ends of the mounting tube are symmetrically connected to side boxes, the lower end of the side box is connected to a stabilizing column, a compression spring is arranged on the inner side of the mounting tube, a rotating shaft is arranged on the inner ring of the gear, one end of the positioning plate is connected to an angle plate, and the end of the angle plate away from the positioning plate is connected to an angle ruler.
[0007] The beneficial effect of the utility model is that when the rotating shaft rotates, the rotating shaft drives the corresponding angle scale to rotate synchronously during the rotation process, which is then used to determine whether the bridge bearing is deformed, and the degree of deformation of the bridge bearing is determined according to the deflection angle of the angle scale. By using two angle scales as a group, comparative data for judging the deflection angle is formed, thereby avoiding deviations in single data. The position disks are connected to form two sets of detection data on both sides of the rubber bearing.

[0016] The beneficial effect of this improvement is that when the rubber bearing exceeds the load and deforms, the force causes the bracket top plate to move downward. At the same time, in this process, the bracket top plate drives the two adjustment rods to move downward and exerts pressure on the compression spring to cause it to deform elastically.
[0017] In order for the gear to drive the connected angle ruler to rotate during the rotation process:
