Description

Technical Field

[0001] This utility model relates to the field of steel pipe flaw detection technology, specifically to flaw detection equipment for stainless steel clean pipes. Background Technology

[0002] Existing stainless steel cleanroom pipes often employ a traveling mechanism that moves inside the pipe during flaw detection, followed by rotational inspection using a probe. This method presents the following problems:

[0003] (1) The probe position is fixed and cannot rotate evenly at the center to test the steel pipe, which is prone to errors.

[0004] (2) The inside of the stainless steel clean tube is smooth, which makes it easy to slip when walking, causing it to tilt forward or backward, resulting in poor stability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a flaw detection device for stainless steel clean pipes, which solves the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel clean tube flaw detection device, comprising a main body, a traveling wheel mechanism located below the main body, and an auxiliary support mechanism located above the main body. An ultrasonic probe driven by a rotary motor is rotatably connected to the surface of the main body. The traveling wheel mechanism includes two telescopic rods rotatably mounted below the main body and a fixed frame. The ends of both telescopic rods are rotatably connected to traveling wheels driven by a motor. A threaded rod extending through and to the outside of the fixed frame is threadedly connected to the inner cavity of the fixed frame. A take-up reel is fixedly connected to the surface of the threaded rod within the inner cavity of the fixed frame. Two pull ropes are connected to the surface of the take-up reel, and the two ends of the pull ropes are respectively connected to the surface of the telescopic rods. The device features a fixed connection at the bottom of the fixed frame, with a fixed cylinder at both ends. A top rod is threaded onto each end of the fixed cylinder. Top plates, which abut against the surfaces of the top rods, are fixedly connected to the sides of the two telescopic rods. During use, the length of the traveling wheels is adjusted by changing the length of the telescopic rods to fit the pipe size. Then, by rotating the top rod, the extension length is adjusted within the fixed cylinder, abutting against the top rod, pushing the telescopic rod to adjust its angle. Rotating the threaded rod drives the take-up wheel, tightening the pull rope. The top rod and top plate apply an outward pushing force to the telescopic rod, while the pull rope applies an inward pulling force. This allows for quick and easy fixing of the opening angle and extension length of the two traveling wheels. The device has a simple structure, is easy to use, and can be used for flaw detection of pipes of various diameters.

[0007] As a further scheme of the utility model: the auxiliary support mechanism includes a reset spring fixed above the equipment main body, the top of the reset spring is fixedly connected with a lifting plate, the top of the lifting plate is fixedly connected with a guide rod, the top of the guide rod is threadedly connected with an adjusting rod, the top of the adjusting rod is rollingly connected with a ball abutting against the top of the inner cavity of the steel pipe, when in use, the position of the ball is adjusted by rotating the adjusting rod, so that after the positioning of the walking wheels is completed, the ball can be quickly adjusted to abut against the top of the inner cavity of the steel pipe for positioning, which can effectively prevent side turning, and when the ball can abut, the ball can move up and down through the extension allowance of the reset spring, which can prevent jamming.

[0008] As a further scheme of the utility model: the top of the equipment main body is fixedly connected with the bottom of the lifting plate through a piston buffer rod, which can guide the lifting plate to only move up and down without deviation.

[0009] As a further scheme of the utility model: the extension end of the telescopic rod is positioned and adjusted in length through a pin shaft.
