Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic flaw detection equipment for steel pipes, in particular to a probe frame of an ultrasonic flaw detection shoe. Background Art

[0002] TRUSCOPE ultrasonic flaw detection equipment is mainly composed of flaw detection system, pre-wetting system and transmission system. The flaw detection system is composed of ultrasonic flaw detection unit (4 lifting and lowering probe shoes), mechanical tracking system, ultrasonic instrument, signal processing system, instrument control and command processing, communication system, etc. The probe frame of each probe shoe is equipped with a wear-resistant sheet, which is in direct contact with the steel pipe for ultrasonic flaw detection. Different specifications of steel pipes require corresponding wear-resistant sheets of different models.

In order to ensure the follow-up stability of the probe shoe, the material of the probe frame is aviation aluminum alloy, which is light and strong, but not wear-resistant. Frequent replacement of the wear-resistant sheet will cause damage to the mounting hole of the probe frame, resulting in the wear-resistant sheet being unable to be fixed, and the entire probe frame can only be replaced. However, the cost of the probe shoe assembly is high and maintenance is inconvenient. Summary of the invention

[0025] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0026] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0027] like Figures 1 to 5 As shown, the utility model provides a probe frame of an ultrasonic probe shoe, comprising a probe frame body 1, a wear-resistant sheet 2 and a threaded sleeve 3.

[0028] The threaded sleeve 3 is a spiral structure formed by winding a steel wire with a diamond cross section. The steel wire can be cold-rolled stainless steel wire. It has the characteristics of wear resistance and high strength. The probe frame body 1 is provided with a threaded hole 8, and the external thread of the threaded sleeve is threadedly connected with the threaded hole, and the external thread diameter of the spiral is larger than the threaded hole diameter. The wear-resistant sheet 2 is threadedly connected with the internal thread of the threaded sleeve through a bolt 9.

[0029] The spiral tail of the threaded sleeve 3 is provided with a mounting handle 4. The mounting handle 4 and the threaded sleeve 3 are an integral structure. A breaking groove 7 is provided between the spiral part of the threaded sleeve 3 and the mounting handle 4.

[0030] The length of the mounting handle 4 is D 安 , the diameter of the internal thread of the threaded sleeve 3 is D, The mounting handle 4 is perpendicular to the central axis of the threaded sleeve 3 , and the mounting handle 4 intersects with the central axis.

[0031] The probe frame body 1 is made of aluminum alloy. A probe membrane 5 and a probe membrane pressing plate 6 are arranged in sequence between the probe frame body 1 and the wear-resistant sheet 2. The probe membrane 5 is made of nitrile silicone. The probe membrane pressing plate 6 is made of stainless steel.

[0032] When installing the threaded sleeve 3 on the probe holder body 1, the installation handle 4 can be clamped with an installation wrench, and then the threaded sleeve 3 is slowly screwed into the threaded hole 8 of the probe holder body perpendicularly. After the threaded sleeve 3 is screwed in, the installation handle 4 is punched out with a punch. There is a breaking groove 7 between the spiral part of the threaded sleeve 3 and the installation handle 4, which is convenient for punching out the installation handle 4 at the breaking groove 7, so as to avoid damaging the thread of the threaded sleeve 3 or causing the position of the threaded sleeve 3 to change.
