Description

Technical Field

[0001] The utility model belongs to the technical field of nondestructive testing, and particularly relates to a wire-type track intelligent walking digital ray detection tooling for intelligent detection of oxide scale inside superheater and reheater tubes of power plant boilers. Background Art

[0002] The screen superheater, high-temperature superheater and high-temperature reheater of the boiler are made of SA-213T91 ferritic CrMo high alloy steel and SA-213TP347 austenitic stainless steel. When these two materials are used at steam temperatures above 566°C, a loose and unstable oxide layer will form on the inner wall of the tube, which will fall off and block the tube, causing the furnace tube to leak due to overheating, or cause the main steam valve of the steam turbine to be stuck and the steam chamber components to be seriously blown. In the SA-213T91 ferritic material serving under supercritical conditions, the heat-affected zone at the welded joint is prone to produce holes due to high-temperature creep. After a period of development, multiple holes are connected to form IV-type creep cracking. In the thermal power unit equipment that has been in service for a long time and is used for peak regulation, the oxide scale peeling and blockage cause the hidden danger of overheating and overheating tube bursting, and the IV-type creep cracking defects that are difficult to detect seriously restrict the long-term safe operation of the thermal power unit. In order to ensure that the amount of oxide scale accumulation can be detected with zero error and IV type creep cracks can be detected in time, and to realize automatic or semi-automatic, digital and information-based detection work, improve work efficiency, reduce labor intensity, meet the inspection requirements of different materials, and ensure the long-term safe operation of boiler equipment, it is necessary to develop a high-efficiency oxide scale monitoring device with zero error, instant display, and human-computer interaction, which is compact, accurate, simple in process, and easy to operate. The oxide scale detection of the tube screen by using a cold cathode ray machine equipped with a ray tool can accurately detect the accumulation of oxide scale inside the official screen, and conduct early preventive inspections of the tube screens in the furnace, which is of great significance.

[0003] However, when the digital radiography device is used to detect the oxide scale of the "four tubes" of the power plant boiler, the digital radiography machine and the imaging board need to be installed on both sides of the tube screen to be detected, and they need to be placed and fixed relative to each other. The distance between the two should be set according to the actual detection focal length. If the tooling is not used, the position of the digital radiography machine and the imaging board needs to be moved, the focus needs to be adjusted, and the next point needs to be taken, and the operation needs to be repeated. The repeated movement, fixing, and focusing of the detection equipment takes a long time, which wastes time for continuous multi-point detection and has low work efficiency.

[0004] Therefore, it is necessary to develop an intelligent tooling for detecting oxide scale inside the superheater and reheater tubes of power plant boilers, which can solve the problem of low efficiency caused by the need to reposition and focus the digital X-ray machine and imaging plate every time they work, especially for continuous shooting and multi-point detection. Utility Model Content

[0005] In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides a wire track intelligent walking digital radiation detection tooling, which can be equipped with a digital radiation machine and an imaging plate for X-ray photography and detection, and can replace manual inspection of the internal oxide scale of the tube panel.

The intelligent walking mechanism is provided with a wire guide device in the vertical direction, thereby driving the digital radiography machine and imaging board suspended under the intelligent walking mechanism to walk in the horizontal and vertical directions, thereby realizing a full range of X-ray photography inspection. Greatly reducing labor intensity and improving work efficiency.

[0007] For tubes that require continuous shooting and multi-point detection, the detection speed is fast, which saves the time of re-placing the detection equipment and repeated focusing. It has the characteristics of easy disassembly and assembly, fast speed and easy to carry. It greatly improves the working efficiency of digital X-ray detection devices in oxide scale detection of power plant boilers, especially suitable for continuous shooting and multi-point detection, realizing intelligent and digital oxide scale detection.
