Description

Technical Field

[0001] The utility model mainly relates to the technical field of bridge detection devices, in particular to a portable bridge rubber bearing detection device. Background Art

[0002] As a key component connecting the superstructure and substructure of a bridge, the bridge bearing has the main function of reliably transmitting the load and deformation (displacement and rotation) borne by the superstructure of the bridge to the substructure of the bridge. The performance of the bearing is directly related to the overall safety and service life of the bridge. The performance of the bearing directly affects the safety and service life of the bridge. If the bearing has cracks, severe shear deformation, voids, dislocation and other defects, it may cause damage to the bridge structure or even collapse. Therefore, strengthening the inspection and maintenance of bridge bearings is of great significance to ensure the safe operation of the bridge. However, the existing bridge bearing inspection usually uses a telescope for visual inspection, which cannot observe details. The equipment specifically used for video inspection is very large and not suitable for people to carry. Therefore, a portable bridge rubber bearing inspection device is needed.

[0003] According to application number CN202121462538.6, a portable bridge rubber bearing detection device is provided, which includes a device plate, a display screen is fixedly connected to the top of the device plate, a detection rod is fixedly connected to one side of the device plate, a camera is fixedly connected to the bottom end of one side of the detection rod, two bottom wheels are installed at the bottom of the device plate, the two bottom wheels move on the top of the bridge side wall, and the bottom of the device plate is fixedly connected to a fixed frame.

[0004] The above document uses a telescopic rod to quickly adjust the position of the side wheel to adapt to different widths of the bridge side wall, and uses an extended camera device to observe the support under the bridge. However, there is a problem that only one side of the bridge rubber support can be observed, and a full-scale observation is not possible. Utility Model Content
