1 问题的提出近年来,管道接口焊缝射线探伤量持续增长,因此长输管道射线拍片的工作量很大,遇到地形复杂或高空管段,不仅机头摆放困难,而且位置稍有偏差就会产生白片头和照偏现象,致使操作人员往返工地重复拍片,耗时费力,影响施工。同时,由于射线机定位是靠一些杂物支撑,遇风或管子振动,极易碰撞,损坏射线机。随着射线探伤工作量的增加,在设备和人员少的情况下,这些问题就更突出,所以管道射线定位紧固器便应运而生。它既能把
1 PROBLEM PROBLEM In recent years, the amount of pipeline flaw detection continues to increase. Therefore, the workload of long-distance pipeline radiography is very high. In the case of complicated or high-altitude pipelines, not only is the nose difficult to place, but the position is slightly deviated Will have a white head and according to partial phenomenon, resulting in duplication of workers from site to repeat, time-consuming and labor-intensive, affecting the construction. At the same time, as the ray machine positioning is supported by some debris, the case of wind or tube vibration, collision easily damage the ray machine. With the increase of the work of radiofrequency detection, these problems are more prominent in the case of less equipment and personnel, so the pipeline ray positioning fastener has come into being. It can both put
