Description

Oil pipe local defect repairing device Technical Field The utility model relates to the technical field of oil pipe repair, in particular to an oil pipe local defect repair device. Background In petroleum, chemical industry and other industries, oil pipes are key equipment for conveying materials, and the pipe walls of the oil pipes are easy to generate local defects such as cracks, sand holes and the like due to corrosion, abrasion or external force impact. Currently, conventional repair methods for these localized defects mainly include downtime repair welding, replacement of pipe sections, or use of external repair clamps. The shutdown repair welding process is complex, pipeline cleaning and fire operation are required, safety risk is high, and production is interrupted for a long time. The replacement of the whole pipe section is costly, the investment of materials and manpower is huge, and the economic benefit is low for only tiny local defects. Although some external repair fixtures or composite wrapped repair solutions are also provided in the prior art, they still suffer from some drawbacks. For example, most repairing schemes require independent pretreatment procedures such as cleaning and polishing to the defect part before plugging and repairing, and the whole repairing process is tedious and time-consuming, so that the repairing efficiency is affected. Therefore, we propose a device for repairing the local defect of the oil pipe. Disclosure of utility model The present utility model is directed to a device for repairing a local defect of an oil pipe, which solves the above-mentioned problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides an oil pipe local defect prosthetic devices, includes arc clamping shell, connecting plate, cleans repair mechanism and selection supporting mechanism, arc clamping shell has two, and two arc clamping shell rotate through the pivot to be connected, the bottom fixedly connected with connecting plate of arc clamping shell, through locking bolt fixed connection between two connecting plates, the interior terminal surface of arc clamping shell is equipped with cleans repair mechanism, clean repair mechanism includes rubber seal pad, clean wiping cloth, connecting rope and stopper, the mounting groove has been seted up to the interior terminal surface of arc clamping shell, and the fixed embedding has rubber seal pad in the mounting groove, the back of clean wiping cloth is a plurality of connecting ropes to two symmetric distribution's logical groove has all been seted up at the surface both ends of arc clamping shell, and connecting rope passes corresponding logical groove and is connected with the stopper, two be connected with the selection supporting mechanism that is used for adjusting the support between the connecting plate. As a further scheme of the utility model, the back of the cleaning wiping cloth is fixedly adhered with silicone paper. As a further scheme of the utility model, the diameter of the limiting block is larger than that of the through groove. As a further scheme of the utility model, the selective supporting mechanism comprises a U-shaped supporting seat, a sleeve, an adjusting rod and a supporting plate, wherein the supporting seat is inserted between two connecting plates, a locking bolt sequentially penetrates through the connecting plates and the supporting seat and is locked and fixed through nuts, the bottom end of the supporting seat is fixedly connected with the sleeve, the inner end surface of the sleeve is in threaded connection with the adjusting rod, and the bottom end of the adjusting rod is fixedly connected with the supporting plate. As a further scheme of the utility model, staggered anti-skid grooves are formed on the lower surface of the supporting plate. As a further proposal of the utility model, the thickness of the rubber sealing gasket is larger than the depth of the mounting groove. Compared with the prior art, the utility model has the beneficial effects that: the utility model directly integrates the independent cleaning pretreatment step into the repairing tool, thereby remarkably simplifying the operation flow, saving the time, improving the repairing reliability because the cleaning of the sealing element and the sealing surface is ensured, and the device can be selectively additionally provided with a selective supporting mechanism according to the requirement so as to cope with the working condition of uneven ground or needing additional support and improve the stability.
