Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding pipeline quality detection, in particular to a camera device capable of circumferential rotation and an X-ray pipeline crawler. Background Art
[0002] As an efficient and special transportation method, pipeline transportation plays an increasingly important role in the fields of municipal gas transportation, municipal heating pipe networks, and municipal water supply pipelines. At present, domestic large-diameter transportation pipelines are mainly composed of spiral welded steel pipes. In order to ensure the reliable operation of transportation pipelines, it is necessary to strictly ensure the quality of the used spiral steel pipes. Therefore, it is necessary to perform non-destructive testing on the welds of steel pipes to eliminate potential hazards. When spiral welded steel pipes enter the construction site, it is necessary to conduct spot checks on their welding quality to ensure the welding quality of the pipelines. Since most spiral welded steel pipe manufacturers use X-ray digital imaging for factory self-inspection, this detection device is large in volume, high in cost, and requires multiple auxiliary devices to operate in a fixed factory building, and is not suitable for on-site construction detection.
[0003] On-site construction usually uses a portable X-ray flaw detector to conduct spot checks on spiral welded steel pipes. Before detection, it is necessary to mark the gauge distances in sequence along the spiral welds on the inner and outer sides of the entire pipe respectively, so that the detection positions on the inner and outer sides of the pipe welds are at the concentric points. The X-ray emitter is at the center position inside the pipe (i.e., the axis of the X-ray emitter coincides with the axis of the pipe), and the film is on the outside of the pipe. Penetration is carried out through the X-ray emitter. This detection method requires two detection personnel. One detection personnel pushes the bracket carrying the X-ray emitter to near the center point of the marked gauge distance with the corresponding number on the inner side of the pipe, and then uses a laser pen to align the radiation source emission window of the X-ray emitter with the center point of the marked gauge distance on the inner side of the pipe. Another detection personnel pastes the marking tape and the film on the center point of the marked gauge distance with the corresponding number on the outside of the pipe. Since radiation will be emitted during X-ray exposure penetration, the detection personnel need to retreat to a safe distance before performing exposure penetration. After the exposure is completed, the above steps are repeated to detect the entire pipe one by one according to the serial numbers. (For a whole pipe with a diameter of 1.6 meters and a length of 12 meters, generally about 160 detections are required). This detection method has a high working intensity and a low detection efficiency.
[0004] The existing fixed camera is used on the existing X-ray pipeline crawler for detecting butt welds, and it cannot be used for penetration detection at different points on spiral welds. Therefore, it is necessary to improve the existing X-ray pipeline crawler to be applicable to the penetration detection of spiral welds. Summary of the Utility Model

[0018] The camera device capable of circumferential rotation provided by the present utility model has multiple sets of marking points at different heights pre-made on the spiral welds of the inner and outer walls of the pipeline to be detected.

After alignment, the X-ray emitter can be turned on to emit X-rays for radiographing; after completing the radiographing of the first marking point, the detector can, through the image displayed on the control display outside the pipeline to be detected, align the alignment point on the camera with the center of the next marking point, which means that at this time the center of the annular ray emission window of the X-ray emitter is aligned with the center of this marking point, and then the radiographing operation can be carried out. And so on, complete the radiographing operation of all the marking points in this set of marking points; when, after completing the radiographing operation of one set of marking points, performing the radiographing operation on another set of marking points at a different height position from it, the detector can control the driving motor to drive the camera to rotate through the control display outside the pipeline to be detected, so as to adapt to the correspondence of the marking points of the set of marking points at another height position on the spiral weld; the whole process can be completed by one detector. For the radiographing of each marking point on each set of marking points, the detector only needs to perform the alignment operation on the first marking point at the start, and the subsequent radiographing operation can be completed by the alignment point on the camera corresponding to different marking points on the inner side of the pipeline to be detected; and when it is necessary to rotate the camera to correspond to the set of marking points at another height on the spiral weld, it can be achieved only by the detector controlling the driving motor to rotate through the control display. The whole structure is simple and the operation is convenient, and it can be used for the radiographing detection of multiple different marking points of spiral welds, improving work efficiency and reducing work intensity.
[0019] Further, the positive power terminal and the negative power terminal of the camera are respectively connected to the corresponding positive annular ring and negative annular ring through conductive connecting rods, so as to avoid the problem that the power supply wire bundle is wound with rotation when the camera rotates, and ensure that the camera can still maintain a good power-on state during the rotation operation.

[0023] Further, the power supply device can provide supply energy for the driving motor to ensure a stable operating state of the driving motor.

[0047] A number of marking point groups with different heights are pre-made on the spiral welds on the inner and outer walls of the pipeline to be detected. Each marking point group includes multiple marking points at the same height in the axial direction of the pipeline to be detected (for example, the numbers of the films at each marking point at the same height are 1, 11, 21, 31, 41, 51, 61, 71, 81, 91...); the heights of each marking point group are different (for example, the numbers of the films at each marking point on another adjacent marking point group are 2, 12, 22, 32, 42, 52, 62, 72, 82, 92...); during detection, when performing radiographic operation on each marking point group, first paste the corresponding marking tapes and films on the points corresponding to the outside of the multiple marking points of each marking point group; by fixedly sleeving the annular gear 10 on the X-ray emitter 60, and then placing the X-ray emitter 60 inside the pipeline to be detected; before radiographing the first marking point at the start of this marking point group, the detector can align the center point of the annular ray emission window of the X-ray emitter 60 with the center of the first marking point by means of a laser pen, and adjust the pointing position of the calibration camera 30 so that the alignment point of the camera 30 is also synchronously aligned with the center of the first marking point.

[0064] This embodiment provides an X-ray pipeline crawler, as Figures 1 to 5As shown, it includes a pipeline crawler 50, an X-ray emitter 60 and a camera device 100 capable of circumferential rotation of the first embodiment; the pipeline crawler 50 and the X-ray emitter 60 are both used to be placed inside the pipeline to be inspected; and the axis of the X-ray emitter 60 coincides with the axis of the pipeline to be inspected; the X-ray emitter 60 is connected to one end of the pipeline crawler 50 in the direction of travel, and a rolling wheel assembly 63 is arranged below the X-ray emitter 60; the annular gear ring 10 is fixedly sleeved on the X-ray emitter 60, and the X-ray emitter 60 has an annular ray emission window, and the center of the annular ray emission window and the alignment point of the camera 30 can both be aligned with the marked point inside the pipeline to be inspected. By adding the camera device 100 capable of circumferential rotation on the basis of the existing equipment, the detection of the spiral weld pipeline can be realized, and its structure is simple and easy to operate.
