Because the flow of the large-diameter pipeline is large and the pressure born by the inside of the large-diameter pipeline is also large, after the large-diameter pipeline is used for a period of time, the abrasion and corrosion condition of the inner wall of the pipeline needs to be detected, particularly for the pipeline for transporting chemical articles, the quality problem of the large-diameter pipeline is related to the life and property safety in a factory, and therefore, the quality detection of the large-diameter pipeline is indispensable.
The utility model relates to a large diameter pipeline is with detecting fixing device, including detecting pipeline 1, be provided with detection pole 2 in detecting pipeline 1, detection pole 2 includes threaded sleeve 3, threaded rod 4, two threaded rod 4 respectively with the both ends threaded connection of threaded sleeve; and a sliding part 5 is arranged at the outer end part of the threaded rod 4, and the sliding part 5 is in contact with the inner wall of the detection pipeline 1.
After the above structural arrangement is made, the following explanation is made:
1. because the pipeline is in fluid transportation, the problem of abrasion and corrosion of the inner wall of the pipeline is serious because the pressure born by the inner wall of the pipeline is large and the transported object is in nature. And for some large-diameter pipelines with longer service life, the change of the inner diameter of the pipeline after abrasion is very obvious, so that the inner diameter of the large-diameter pipeline is detected to judge whether the thickness of the inner wall of the pipeline meets the standard of application of the pipeline after the pipeline is used for a long time, and further the problem that the pipeline cannot bear the pressure during transportation due to excessive corrosion of the inner wall of the pipeline is avoided, so that the potential safety hazard during transportation of the pipeline is avoided.
2. When the inner wall to big pipe diameter pipeline detects the measurement, because the internal diameter size of pipeline is great for some traditional inspection work are difficult to detect the pipeline internal diameter, and because the pipeline inner wall is serious through wearing and tearing behind the corruption, and then some external measuring equipment can't effectively detect the size change condition that obtains the pipeline inner wall. Moreover, due to the fact that the inner diameter of the pipeline is large, when the pipeline is detected, the position of the diameter size of the pipeline cannot be found correctly, the measured size is not the inner diameter size of the pipeline, the problem of error detection of the inner diameter of the pipeline is caused, and the detection rigidness is not met.
After setting up above-mentioned structure, the test rod 2 that at first sets up includes threaded sleeve 3, threaded rod 4, because the pipeline internal diameter that will carry out the measurement is different, consequently cooperates the back at threaded sleeve 3 and threaded rod 4, can rotate for threaded sleeve 3 through threaded rod 4 to realize the regulation of 2 whole lengths of test rod, and then when measuring different pipeline pipe diameters, make things convenient for the staff to operate more. When the detection rod 2 is arranged, the sliding part 5 is arranged at the outer end position of the threaded rod 4, so that the threaded rod 4 is in contact with the inner wall of the pipeline, and when the threaded sleeve 3 rotates outwards relative to the threaded rod 4 to expand, the sliding part 5 is in the inner diameter position of the pipeline because of being in contact with the arc surface of the inner wall of the pipeline, the sliding part 5 can slide relative to the inner wall of the pipeline at the moment, and when the length of the detection rod 2 continues to expand outwards and the position of the sliding part 5 is not changed easily, the detected length is the diameter length of the inner diameter of the pipeline at the moment. When the detection rod 2 is used, the direction in which the detection rod 2 is arranged needs to be ensured to be vertical at first, so that when the detection rod 2 is used, the detection rod 2 can be attached to the port of a large-diameter pipeline to be arranged, and the arrangement direction of the detection rod 2 is ensured to be vertical. Of course, because the positions of the two threaded rods 4 can be rotated relative to the threaded sleeve 3, the length of the detection rod 2 can be conveniently adjusted by a worker in the directions of the two ends, and the following beneficial effect of facilitating the installation of the detection device can be achieved.
