Description

Technical Field

[0001] The invention specifically relates to a pipeline nondestructive testing device, and belongs to the technical field of pipeline nondestructive testing. Background Art

[0002] Pipelines are components used to transport liquids, gases, and particulate solids in real life. After the pipeline manufacturing process, the quality of the pipeline needs to be tested to ensure that the pipeline can be used for a long time, safely, and stably after installation. Existing pipelines are usually directly formed, and quality problems are usually prone to occur at the welds of the pipeline. Therefore, non-destructive testing of the welds of the pipeline is required. In the prior art, radiographic testing technology is usually used for precise non-destructive testing of pipeline welds. The radiographic device is used in conjunction with the film to allow the radiographic device to irradiate the specific conditions of the weld onto the film through the radiographic method. The film is then moved to a professional imaging room, and the quality problems of the pipeline welds are determined by judging the exposure of the film to the weld.

[0003] However, the ray emitting device in the prior art is heavy, and during the production process of the pipeline, multiple pipelines are usually welded together. Therefore, it is necessary to detect multiple welds on the pipeline, which requires the ray emitting device to move in the pipeline test area, and enable the ray emitting device to detect multiple welds on the pipeline in sequence. However, according to the different inner diameters and thicknesses of the pipeline, the use of the ray emitting device is also different. For some pipelines with smaller inner diameters and thinner thicknesses, it is necessary to move the ray emitting device outside the pipeline, irradiate the pipeline from the outside, and fix the film on the side opposite to the ray emitting device; when performing ray detection on pipelines with larger inner diameters and thicker textures, it is necessary to move the ray emitting device inside the pipeline, fix multiple film circumferences around the welds, and expose once inside the pipeline through the ray emitting device, thereby completing the detection of the welds. However, in the prior art, it is difficult to drive the ray emitting device to move stably inside or outside the pipeline according to pipelines with different inner diameters and thicknesses, resulting in inconvenience in using ray detection equipment to detect pipeline welds.

[0046] The working principle of the pipeline nondestructive testing device of the present invention is as follows:

[0047] When it is necessary to inspect the pipeline weld, first adjust the position of the mounting plate 35 so that the pipeline can contact with the multiple support rollers 10 during the lifting and lowering process, and reduce the gravity of the pipeline when it is lowered through the spring damper 34; then start the driving electric cylinder 33 to drive the connecting piece 32 and the multiple lifting frames 8 to descend, so that the pipeline descends between the tops of the multiple driving wheels 39, and then drive the driving shaft 38 to rotate through the motor driving device 40, so as to drive the pipeline to flip between the multiple support rollers 10, so that the inspector can set a negative film at the weld of the pipeline;

[0048] When the ray emitting device 2 needs to be moved inside the pipeline, after the pipeline is placed, first, one of the moving cylinders 4 is passed through the pipeline, and the two moving cylinders 4 are respectively moved to the two sides of the ray emitting device 2, and the transmission worm 18 corresponding to the clamping member 5 is rotated to drive the corresponding transmission worm wheel 17 to rotate, so that the threaded disk 14 rotates inside the moving cylinder 4, and the clamping member 5 is driven to move through the sliding block 16, and the fixing ring 3 is clamped and fixed by the clamping member 5; then, the transmission worm 18 corresponding to the sliding rod 11 is rotated to drive the corresponding transmission worm wheel 17 and the threaded disk 14 to rotate. 4 rotates, thereby driving the multiple sliding rods 11 to slide on the moving cylinder 4, so that the multiple rotating wheels 12 are all in contact with the inner wall of the pipeline; then, the driving motors 22 located on both sides are started to drive the winding drum 21 to rotate on the rotating seat 20 to complete the winding or unwinding operation of the traction rope 6, thereby driving the moving cylinder 4 and the ray emitting device 2 to move horizontally through the traction ropes 6 on both sides; finally, when the ray emitting device 2 is moved to the weld position in the pipeline, the ray emitting device 2 is used to expose the inside of the pipeline; through the cooperation of the ray emitting device 2 and the film, the pipeline weld is inspected; thereby realizing non-destructive testing of pipelines with larger inner diameters;

[0049] When it is necessary to move the ray emitting device 2 to the outside of the pipeline, first, the fixed seat 24, the fixed slide groove 26 and the top slide rail 7 are flipped outward along the center point of the rotating shaft 25 to the outside of the fixed frame 1. After the pipeline is placed between the tops of multiple driving wheels 39, the fixed seat 24, the fixed slide groove 26 and the top slide rail 7 are flipped inward along the center point of the rotating shaft 25 to the top of the fixed frame 1. Then, the top of the fixed seat 24 and the fixing part 23 are fixed by bolts. Next, the sliding wheel 13 is moved into the top slide rail 7, and the sliding wheel 13 is moved on the top slide rail 7 by the traction rope 6, so that the movable cylinder 4 and the ray emitting device 2 are moved between the two top slide rails 7, and the ray emitting device 2 is driven to move to the weld of the pipeline to perform flaw detection on the weld of the pipeline, thereby realizing non-destructive testing of pipelines with smaller inner diameters.
