Problems solved by technology
However, when repairing online pipelines, it is generally necessary to dig out the pipelines for repair, which makes the repair difficult. Although some repair devices in the prior art can extend into the pipeline for repair, they cannot match pipelines of different sizes The use of it makes its stability during the movement not good enough, which affects the repair work. For this reason, it is necessary to continue in-depth research

The invention discloses an online pipeline repairing device, and relates to the field of pipeline repairing. The online pipeline repairing device comprises a repairing assembly located in an online pipeline. The repairing assembly comprises a main installing box. Auxiliary installing boxes are arranged on the two sides of the main installing box. Electric cylinders are fixed to the two sides of the main installing box. Piston rods of the two electric cylinders are fixed to the two auxiliary installing boxes. The end portions of the two auxiliary installing boxes are fixedly provided with rectangular insertion rods which are movably inserted into the main installing box. The two ends of the auxiliary installing boxes are rotationally provided with rotating shafts correspondingly. The two rotating shafts are fixedly provided with advancing wheels which extend out of the auxiliary mounting boxes correspondingly. Due to the arrangement of a stepping motor, a gear ring, a rectangular rotating rod, a sleeve, a driving bevel gear, the rotating shafts, the advancing wheels and a driven bevel gear, the device can move in the length direction of an online pipeline, walking can still be realized after the distances between the auxiliary installing boxes and the main installing box are adjusted, and moving stability is realized accordingly.
Description
Technical field[0001]The invention relates to the field of pipeline repair, in particular to an online pipeline repair device.Background technique[0002]Pipeline repair refers to the use of various technologies for damaged and leaked transportation pipelines to restore normal use functions. The repair includes two technologies: external anticorrosion repair and internal repair: for internal and external anticorrosion repair, it refers to the external anticorrosion coating of pipeline Carry out the inspection and evaluation of the outer anti-corrosion layer and then repair it according to the evaluation report; the inner repair is to fully impregnate the fiber hose with impermeable membrane with resin, and use air or water pressure to turn it over and close to the inner wall of the old pipe. After solidification, a smooth lining glass steel pipe is formed, thus completing the repair of the old pipeline. However, at present, when repairing online pipelines, it is generally necessary to...
