[0001] This utility model relates to the field of ultrasonic testing technology, and in particular to a non-contact ultrasonic testing bracket for underwater ship hull structures. Background Technology

[0002] When working on underwater hull structures, ultrasonic testing is often required. Traditional non-contact ultrasonic testing brackets have relatively fixed positions for the transmitting and receiving probes, making it impossible to adjust their positions as needed. In addition, the transmitting and receiving probes are generally fixed in place, making them inconvenient to disassemble. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-contact ultrasonic testing bracket for underwater hull structures.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a non-contact ultrasonic testing bracket for underwater hull structures, comprising a mounting frame, wherein two positioning rods are inserted through the top of the mounting frame, and a first support plate is fixedly connected to the top of each of the two positioning rods; two vertical poles are fixedly connected to the upper surface of the first support plate, and a second support plate is fixedly connected to the top of the two vertical poles; mounting plates are slidably connected to the upper surfaces of the two second support plates; a reflective probe is fixedly connected to the upper surface of one mounting plate, and a receiving probe is fixedly connected to the upper surface of the other mounting plate; a rotating disk is rotatably connected to the inner top of the mounting frame, and two sets of positioning components are installed on the outer surface of the rotating disk.

[0005] As a further description of the above technical solution:

[0006] A sliding block is slidably connected to the lower surface of the mounting plate, and a first sliding groove is provided on the upper surface of the second bracket plate, with the sliding block slidably connected inside the first sliding groove.

[0007] As a further description of the above technical solution:

[0008] Multiple fixed shafts are fixedly connected to the upper surface of the rotating disk. Limiting sliders are fixedly connected to the top of the fixed shafts. An annular groove is provided on the inner top of the mounting bracket. The limiting sliders are movably disposed inside the annular groove to ensure that the rotating disk can rotate normally.

[0009] As a further description of the above technical solution:

[0010] The lower surface of the second bracket plate is threaded with a first bolt. The end of the first bolt passes through the second bracket plate and abuts against the lower surface of the mounting plate, thereby fixing the mounting plate.

[0011] As a further description of the above technical solution:

[0012] The rotating disk is threaded with a second bolt at its center, and the end of the second bolt is threaded to the inner top of the mounting bracket, thereby fixing the rotating disk.

[0013] As a further description of the above technical solution:

[0014] The positioning component includes a drive rod rotatably connected to the outer surface of a rotating disk. A positioning latch is rotatably connected to the end of the drive rod away from the rotating disk. The end of the positioning latch away from the drive rod is engaged with a corresponding positioning plug. A positioning hole adapted to the positioning plug is provided on the side wall of the positioning plug. The positioning component can be used to limit the positioning of the positioning plug.

[0015] As a further description of the above technical solution:

[0016] A sliding strip is fixedly connected to the upper surface of the positioning rod, and a second sliding groove is provided on the inner top of the mounting bracket. The sliding strip is slidably connected inside the second sliding groove, which can ensure the stable movement of the positioning rod.

[0017] This utility model has the following beneficial effects:

[0018] 1. Compared with existing technologies, this non-contact ultrasonic testing bracket for underwater hull structures allows for easy insertion of a positioning rod onto a mounting bracket. Rotating the rotating disc causes the drive rod to move along with the positioning latch, engaging the end of the positioning latch away from the drive rod with the corresponding positioning rod. Tightening the second bolt then connects it to the mounting bracket, securing the rotating disc and limiting the positioning rod's position. For disassembly, first loosening the second bolt separates it from the mounting bracket. Then, rotating the rotating disc causes the drive rod to move along with the positioning latch, disengaging the positioning latch from the positioning rod, allowing the reflector and receiver probes to be removed. The operation is simple and convenient, facilitating assembly and disassembly.

[0019] 2. Compared with existing technologies, this underwater hull structure non-contact ultrasonic testing bracket allows for the adjustment of the positions of the reflective and receiving probes by loosening the first bolt, which prevents it from contacting the lower surface of the mounting plate. This makes it suitable for various needs. Attached Figure Description
