Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge measurement, in particular to a bridge support deformation angle measuring device. Background Art
[0002] A bridge is generally composed of an upper structure, a lower structure, supports and ancillary structures. The upper structure, also known as the span structure, is the main structure for crossing obstacles; the lower structure includes abutments, piers and foundations; the supports are force transmission devices installed at the supporting locations between the span structure and the piers or abutments; the ancillary structures refer to the bridge head cladding, conical slope protection, bank protection, diversion projects, etc.
[0003] During the long-term use of the bridge, the bridge bearing will be subjected to a large load, which will cause the bridge bearing to tilt and deform. In order to ensure the safety of the bridge, the bridge bearing needs to be inspected regularly. When the bridge bearing is found to be seriously tilted, the bridge bearing needs to be replaced. At present, the inclination angle of the upper bearing steel plate or the lower bearing steel plate of the bridge bearing is mainly measured by an inclinometer, and then the inclination amplitude of the entire bridge bearing is judged based on this. During the inspection, the inclinometer needs to be attached to the bottom of the upper bearing steel plate or the top of the lower bearing steel plate, and the pointer on the inclinometer will point to the corresponding angle value, thereby obtaining the inclination amplitude of the upper bearing steel plate or the lower bearing steel plate. However, this measurement method is not based on the entire bridge bearing, which makes it impossible to accurately judge whether the bridge bearing is tilted by the upper and lower bearing steel plates or the entire bearing, which affects the judgment of the service life of the bridge bearing.

[0029] The two arc-shaped fixed frames 1 are slidably connected with a sliding frame 8. The upper end surface of each arc-shaped fixed frame 1 is provided with an arc-shaped T-shaped slide groove 7, and the two arc-shaped T-shaped slide grooves 7 are connected, and the sliding frame 8 is slidably connected in the arc-shaped T-shaped slide groove 7. During the movement of the angle measuring component, the inclined connecting frame 10 drives the sliding frame 8 to move in the arc-shaped T-shaped slide groove through the threaded sleeve 9, which can drive the angle measuring component to move around the bridge pier to measure the deformation angle of different positions of the bridge support;
[0030] The inclined connecting frame 10 includes two symmetrically arranged base rods, an extended threaded barrel is obliquely arranged on the lower end base rod, a threaded hole is obliquely opened on the lower end surface of the upper end base rod, and the extended threaded barrel is threadedly connected in the threaded hole, so that the overall length of the inclined connecting frame 10 can be adjusted to ensure that the upper end of the angle measuring assembly contacts the lower end surface of the bridge support, and ensure that the upper surface of the arc angle frame 13 is completely in contact with the lower end surface of the bridge support;
[0031] Both ends of the inclined connecting frame 10 are fixedly connected with threaded columns 15, the upper end of the sliding frame 8 is fixedly connected with a threaded sleeve 9, and the threaded column 15 connected to the lower end of the inclined connecting frame 10 is threadedly connected with the threaded sleeve 9;
