Embodiment Construction

[0032] A kind of tank car real-time imaging transillumination method provided by the present invention, the implementation mode of this method is as follows:

[0033]1) The tank to be tested is subjected to single-wall inspection when the last circular seam is not welded, the ray generator is inserted into the tank to be tested through the probe arm, and the image intensifier is located outside the tank to be tested; Load the body into the transillumination room, adjust the position of the tank so that the image intensifier placed outside the tank to be tested, the starting point of the weld on the tank to be tested, and the center of the ray generator placed inside the tank to be tested are on the same straight line , and the straight line is located on any diameter extension line of the tank body; the distance between the roller of the tank carrying trolley and the edge of the weld seam of the tank body to be tested is kept at least 100mm, so as to avoid certain influence on ...

Abstract

The invention relates to a real time imaging transillumination method and system for a tank car. The system comprises an image booster support mobile unit and a ray generator support mobile unit; the ray generator support mobile unit comprises a feeler arm and a feeler arm support mobile means which enables the feeler arm to carry out two-dimensional movement, and the feeler arm is arranged on the feeler arm support mobile means; the image booster support mobile unit comprises an image booster and an image booster support mobile means which is used for adjusting the position of the image booster, and the image booster is arranged on the image booster support mobile means. The invention enables the technical problem that it is difficult to carry out real time imaging detection because tanks of different types are of different sizes and structures in the prior art to be overcome; real time imaging detection of weld joints of tanks can be realized in the invention by adjusting the distance and position of the image booster, a ray generator and the weld joints of the tanks according to sizes and structures of the tanks, and accurate detection results and high detection efficiency are realized.

Description

technical field [0001] The invention relates to a real-time imaging transillumination method and system, in particular to a real-time imaging transillumination method and a transillumination system for the weld seam of a tank body of a railway tanker. Background technique [0002] After the welding of railway tank cars is completed, radiographic testing is usually used to check whether the welds are qualified. The conventional method currently used is radiography, that is, the inspection of weld seams is completed by filming, developing, and evaluating films. However, the detection speed of this method is slow, the detection cost is high, and the detection period is long, which cannot meet the requirements of radiographic detection of large quantities of general-purpose tank cars. Another method is the real-time imaging method. Although the real-time imaging method has high detection speed and low detection cost, the detection result can be obtained in real time. However, ...
