Description

Technical Field

[0001] The utility model relates to an ultrasonic detection device for steel structure bridge welds, belonging to the technical field of steel structures. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. The components or parts are usually connected by welds, bolts or rivets. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust, and general steel structures need to be derusted, galvanized or painted, and need to be maintained regularly.

[0003] Chinese Patent (Publication No.: CN 218331376 U3) discloses an ultrasonic detection device for steel structure welds, including a detection platform and an ultrasonic detection device. A steel plate body is placed on the detection platform, and a rotating assembly is installed on the detection platform. An installation frame is fixedly installed on the bottom side of the rotating assembly;

[0004] When the ultrasonic detection probe of this ultrasonic detection device for steel structure welds performs ultrasonic detection on the weld on the steel plate body, through the pulling assembly, the ultrasonic detection probe can be driven to move through the sliding adjustment assembly. By sliding back and forth, the weld on the steel plate body can be detected. When detecting welds in other directions, the staff presses the motor controller, and the rotating motor on the rotating assembly will run. Again, by manually pulling the rod, the ultrasonic detection probe can be driven to move, so that the welds in other directions can be detected. During the detection process, it is not necessary to adjust the position of the steel plate body back and forth, which reduces the labor intensity of the staff in adjusting the steel plate body. However, the detection device in the above patent can only detect one side of the steel plate body and cannot detect the upper and lower sides of the steel plate body at the same time, resulting in the need to detect the other side again after detecting one side of the steel plate body, prolonging the detection time and having a relatively low detection efficiency.

[0005] Therefore, an ultrasonic detection device for steel structure bridge welds is proposed. Utility Model Content

[0029] By setting up the two-way detection mechanism 3, the welds on both the upper and lower sides of the steel plate body can be detected simultaneously, eliminating the need to turn over the steel plate body for detection, reducing the detection time of the steel plate body, and improving the working efficiency during detection.

[0030] Embodiment 2

[0031] In one embodiment, the connecting plate 401 is fixedly connected to the left side inside the U-shaped plate 303. The threaded rod 402 is rotatably connected to the right side of the connecting plate 401 through a bearing. The first bevel gear 403 is fixedly connected to the right side of the threaded rod 402. The second bevel gear 404 is located on top of the first bevel gear 403, and the first bevel gear 403 and the second bevel gear 404 are meshed with each other through teeth.

[0033] Embodiment 3

[0034] In one embodiment, annular sliding grooves 7 are respectively formed on the left and right sides inside the detection table 1.

[0036] When the utility model works: First, when it is necessary to detect the steel plate body, the steel plate body is first placed on the top of the placing plate 5.

And during the detection process, the output shaft of the servo motor 405 can also be rotated to drive the second bevel gear 404 to rotate. The second bevel gear 404 drives the first bevel gear 403 to rotate through the meshing of the teeth. The first bevel gear 403 drives the threaded rod 402 to rotate, thereby driving the threaded sleeve 406 to move left and right, and then driving the ultrasonic detection probe 6 to move left and right, improving the detection range of the ultrasonic detection probe 6. The ultrasonic detection probe 6 feeds back the detection result to the ultrasonic detection device 2, which is convenient for people to know in time.
