Description

Automatic repairing device for petroleum lining oil pipe Technical Field The invention belongs to the technical field of multifunctional machine tools, and particularly relates to an automatic repairing device for an oil lining pipe. Background The oil fields in China are numerous, a large number of waste oil pipes are generated each year, and the waste oil pipes are generally used for recycling or being used as scrap iron and the like for returning to the furnace for re-smelting, so that resources are wasted, the environment is a burden, and most of the waste oil pipes can be reused only through repair treatment. The pumping pipe used on the pumping well of the current oil field can not be used continuously due to different degrees of abrasion of the inner wall and the outer wall after being used for a period of time, and a new oil pipe needs to be replaced, so that a large amount of waste oil pipes can be generated to cause waste. Through research experiments on replaced waste oil pipes, the technology indexes such as mechanical strength and hardness of most oil pipes can meet the technological requirements after the oil pipes are subjected to equipment repairing treatment, and the oil pipes can be recycled and reused completely. The publication No. CN209491524U discloses a waste oil pipe regeneration device, which comprises an oil pipe conveyor and a high-frequency induction heating device, a sand blaster, an oil pipe hot rolling repair device, an annealing cooling box, an ultrasonic flaw detector, a hyperbolic roller straightening machine, an electric pipe cutting threading machine and an automatic coding machine, wherein the high-frequency induction heating device, the sand blaster, the oil pipe hot rolling repair device, the annealing cooling box, the ultrasonic flaw detector, the hyperbolic roller straightening machine, the electric pipe cutting threading machine and the automatic coding machine are arranged between the two oil pipe conveyors and are electrically connected with an electrical control cabinet, the oil pipe is heated through the high-frequency induction heating device, oil dirt is melted and flows out to the oil dirt collecting box to be collected, then the oil pipe is polished through the sand blaster, the oil pipe is hot rolled and repaired through the oil pipe repairing device, the repaired oil pipe is cooled down in the annealing cooling box, and then the oil pipe is sequentially subjected to flaw detector, the electric pipe cutting threading machine and the automatic coding machine under the action of a driving roller, and finally subjected to flaw detection, straightening and coding machine and finishing the whole coding process. Although the device can restore oil pipe, the inside of some oil pipe is provided with interior bushing pipe, and interior bushing pipe needs to be changed after long-time use, uses the haulage equipment to pull old interior bushing pipe out from oil pipe's inside, but haulage equipment is when the lining pipe in the pull, and haulage equipment's travel distance is greater than the length of interior bushing pipe, and consequently the area that occupies is great, can't satisfy the user demand in little place.
