Description

Technical Field

[0001] The utility model relates to the technical field of measuring angles or tapers and detecting axis collimation, and particularly relates to a bridge bearing deformation angle measuring device. Background Art

[0002] During the process of supporting the bridge, the bridge bearing is subjected to a large load. Over a long time, the angle or shape of the bridge bearing may change. To avoid accidents such as bridge collapse, it is necessary to frequently measure the bridge bearing to prevent serious deformation. Most of the existing bridge bearing deformation angle measuring devices are directly placed on the side of the bridge bearing for measurement when in use. Due to the limitation of the size of the measuring tool, the measuring tool for the bearing has great limitations and cannot fit well with the bridge bearing, so it is impossible to measure bridge bearings of different specifications. At the same time, it is inconvenient to fix and store the measuring tool, and thus inconvenient for transportation. Therefore, a bridge bearing deformation angle measuring device is needed to solve the above problems. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the prior art such as the inability to measure bridge bearings of different specifications, and thus propose a bridge bearing deformation angle measuring device.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A bridge bearing deformation angle measuring device includes a fixed rod. At both ends on one side of the fixed rod, cross bars are horizontally and fixedly arranged. On both sides of the top of the fixed rod, fixed blocks are fixedly arranged. A rotating rod is fixedly connected between the two fixed blocks, and the rotating rod is located on the top of the fixed rod. A rotating plate is rotatably arranged on the top of the fixed rod, and the rotating plate is located between the two fixed blocks. A rotating hole is longitudinally opened inside the bottom of the rotating plate, and the rotating rod is rotatably arranged in the rotating hole.

[0005] Further, a groove is longitudinally opened inside one side of the fixed rod. A bidirectional screw rod is longitudinally rotatably arranged inside the groove, and bearings are sleeved at both ends of the bidirectional screw rod. One end of the bidirectional screw rod is fixedly provided with a handle, and the handle is located outside the fixed rod.

[0006] Further, threaded blocks are threadedly arranged at both ends of the bidirectional screw rod, and the threaded blocks are located inside the groove. At one end of each of the two threaded blocks, a clamping plate is horizontally and fixedly arranged, and the two clamping plates are located between the two cross bars. At the inner end of each of the two clamping plates, a friction plate is fixedly arranged, and the friction plate is made of rubber material.

[0007] Further, clamping rods are fixedly arranged at the centers of the front and rear ends of the rotating plate. Connecting blocks are fixedly arranged at the tops of one side of the two clamping plates. Through holes are opened at the centers of the end faces of the two connecting blocks, and the two clamping rods are respectively adapted to the two through holes.

[0008] Furthermore, a fixed pointer is fixedly arranged at the bottom of the front end of the rotating plate, a protractor is horizontally fixedly arranged on one side of the top of the fixed rod, and one end of the bottom of the protractor is fixedly arranged on one of the cross bars. An arc-shaped chute is formed on the outer end face of the protractor, and the outer end of the fixed pointer is slidably arranged in the arc-shaped chute.

[0009] The beneficial effects of the present utility model are as follows: By rotating the handle, it is convenient to drive the bidirectional screw to rotate, so that the two threaded blocks drive the two clamping plates to move closer to each other. Furthermore, the bridge bearing is clamped by the two friction plates, so that the measuring tool can be well attached to the bridge bearing, and thus it is convenient to measure bridge bearings of different specifications, thereby expanding the usage range of the measuring tool; At the same time, rotate the rotating plate so that it fits horizontally with the fixed rod. Rotating the handle conveniently drives the bidirectional screw to rotate, so that the two threaded blocks drive the two clamping plates to move closer to each other, and then drive the two connecting blocks to move closer to each other, so that the clamping rods at both ends of the rotating plate are respectively inserted into the through holes on the two connecting blocks, thus facilitating the fixation of the rotating plate and the fixed rod, and further facilitating the fixed storage of the measuring tool, thereby facilitating transportation.
