Description

Technical Field

[0002] The pipeline crawler is a device used to take circumferential X-rays of the butt welds of pipelines. It is mainly used for non-destructive testing of various pipelines such as natural gas pipelines, oil pipelines, urban water supply and drainage pipelines, and tap water pipelines, providing strong technical support for the safe operation of pipelines. Generally, the flaw detection device is brought into the pipeline by a traction trolley. The flaw detection device is a circumferential X-ray flaw detector. When the ray emission window of the X-ray flaw detector is aligned with the weld position, the X-ray flaw detector is magnetically positioned to expose the butt welds of the pipeline according to the set exposure voltage and exposure time, thereby displaying pipeline defects. At present, the X-ray flaw detector is generally fixed to the crawler by bolts and screws. The fixing and disassembly process is relatively complicated, which is not convenient for installation and later maintenance. Utility Model Content

The output end of the cylinder 24 passes through the front slide plate 22 and is fixed with a front baffle 25. The front baffle 25 can abut against the front end of the flaw detector 11; a rear baffle 26 is fixed to one side of the rear slide plate 23, and the rear baffle 26 can abut against the rear end of the flaw detector 11; a blocking block 27 is provided on the body 10 for limiting the movement of the front baffle 25 and the rear baffle 26.

[0018] The output end of the control cylinder 24 extends out, driving the front baffle 25 to abut against the front end of the flaw detector 11, and the slide rod 21 slides along the vehicle body 10, so that the rear baffle 26 abuts against the rear end of the flaw detector 11, so as to fix the flaw detector 11 on the vehicle body 10 of the crawling device. When disassembling, the output end of the control cylinder 24 is retracted to separate the flaw detector 11 from the vehicle body 10, thereby simplifying the fixing and disassembly process and facilitating installation and subsequent maintenance.

[0019] Among them, the flaw detector 11 is generally composed of a controller, an X-ray generator, a connecting cable, a power cable, etc.; the positioning method of the pipeline crawling device in the pipeline is magnetic positioning, and the technical parameters of the pipeline crawling device can be selected according to actual applications; the specific working methods of the flaw detector 11 and the pipeline crawling device are both existing technologies and will not be repeated here.

[0020] The cylinder 24 as a driving mechanism may also be replaced by a hydraulic cylinder or a motor screw nut structure.

[0021] The connection method and driving method of the wheel 12 are prior arts and will not be described in detail here.

[0022] Preferably, a fixing frame 13 is provided at both the front and rear ends of the flaw detector 11, and the fixing frame 13 is a square ring structure; a limit plate 28 is fixed on the front slide 22 and the rear slide 23, and the limit plate 28 can extend into the fixing frame 13; the front slide 22 can abut against the fixing frame 13 at the front end of the flaw detector 11, and the rear slide 23 can abut against the fixing frame 13 at the rear end of the flaw detector 11, so as to prevent the flaw detector 11 from moving in the axial and radial directions at the same time.

The slide bar 21 slides along the vehicle body 10, driving the rear baffle 26 to disengage from the fixing frame 13 at the rear end of the flaw detector 11 until the rear baffle 26 abuts against the corresponding blocking block 27, thereby canceling the fixation of the flaw detector 11, thereby separating the flaw detector 11 from the vehicle body 10.
