[0002] Pipeline flaw detection is mainly used for non-destructive flaw detection of pipeline welds, corrosion and cracks in petroleum, chemical, power and other industries. During the flaw detection process, it is usually necessary to use a driving device to move and rotate the pipeline. The displacement device for girth weld inspection still adopts switch control, and the pipe fittings cannot be automatically conveyed, etc., the flaw detection efficiency is low, the operation labor intensity is high, and there is a threat of X-ray radiation to the human body

Embodiment 1
[0013] This embodiment provides a driving device for flaw detection of pipeline welds, the structure of which is as follows: figure 1 As shown in Figure 3, it consists of a heavy-duty bending pipe driving device 1, a driven roller frame 2 and a track module 3. The track module 3 is mainly a track for the heavy-duty bending pipe driving device and the driven roller frame to travel. The heavy-duty bending pipe driving device 1 is composed of a trolley part 4, a base part 5, a roller frame part 6, a heavy-duty column 7, a pressing arm part 8 and a cable reel 12; the trolley part 4 can be electrically driven on the track module , has the function of positioning and locking, and has eight walking wheels at the same time, mainly to prevent radiation. The track module is disconnected by 180mm at the indoor door frame, but the heavy-duty elbow driving device can still drive on this track module under the load. walk. The parts of the trolley are mainly composed of a wheel device 9, a ...

The invention relates to a pipeline weld seam flaw detection driving device which mainly comprises a heavy-load bend driving device, a driven roller carrier and a rail module and can be adaptable to clamping of pipes in different diameters and lengths. The bend driving device can effectively control eccentric force of eccentric pipe fitting in rotation to guarantee stability in an imaging process, and workpieces can be paused in rotation, rotate forwards or backwards, and realize variable-frequency speed regulation. After being fed from a flaw detection room, the pipe fittings can be pressed, automatically conveyed, discharged and loosened, and can rotate automatically. Owning to an assembly line work manner for discharging of the pipe fittings, the difficult problem that the pipeline weld seam flaw detection driving device cannot run smoothly due to the fact that a rail at a lead door of the radiative flaw detection room is broken is solved.
Description
technical field [0001] The invention relates to a driving device for flaw detection of pipeline welds, belonging to the technical field of pipeline flaw detection tooling. Background technique [0002] Pipeline flaw detection is mainly used for non-destructive flaw detection of pipeline welds, corrosion and cracks in petroleum, chemical, power and other industries. During the flaw detection process, it is usually necessary to use a driving device to move and rotate the pipeline. Currently, the middle of the factory prefabricated pipe The displacement device for girth weld inspection still adopts switch control, and the pipe fittings cannot be automatically conveyed. The flaw detection efficiency is low, the operation is labor-intensive, and there is a threat of X-ray radiation to the human body. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a driving device for fla...
