A device for repairing deformed casing

Abstract

The invention discloses a deformed casing repairing device and belongs to the technical field of deformed casings. The deformed casing repairing device comprises an antisticking hydraulic anchor, a travel booster, a hydraulic accumulator, an intelligent commutator, a hydraulic impactor and a split expansion pipe joint, wherein a lower joint of the antisticking hydraulic anchor is in seamless joint with an upper joint of the travel booster, the lower end of the travel booster is in seamless joint with the upper end of the hydraulic accumulator, and the lower end of the hydraulic accumulator is in seamless joint with the upper end of the intelligent commutator; the lower end of the intelligent commutator is in sealed joint with the upper end of the hydraulic impactor, and a sixth impact cavity of the intelligent commutator is in communicated joint with a hydraulic impactor core tube of the hydraulic impactor; an impact head of the hydraulic impactor is contacted with a boosting block on the split expansion pipe joint. The provided deformed casing repairing device can overcome defects of a conventional repairing technology, continuously repairs a casing and is controllable in repairing, high in repairing efficiency and low in repairing cost.

Description

technical field [0001] The invention belongs to the technical field of deformed sleeves, and relates to a repairing device for deformed sleeves. Background technique [0002] At present, the methods to solve the problem of casing deformation mainly include explosive shaping and mechanical shaping. [0003] In the explosive shaping technology, it is difficult to accurately control the dosage of the drug. The casing at the deformed part is often accompanied by uneven wall thickness, and the explosion has no direction, which inevitably causes great damage to the casing. [0004] In mechanical shaping, pear-shaped device expansion technology, casing grinding and milling technology, eccentric roller shaping technology, rotary shock technology, ball shaping technology, etc., generally exist damage to the casing, sacrifice the thickness of the casing, and it is difficult to restore the original diameter. Long cycle, large investment and other issues. [0005] The common character...

AI Technical Summary

Problems solved by technology

[0003] In the explosive shaping technology, it is difficult to accurately control the dosage of the drug. The casing at the deformed part is often accompanied by uneven wall thickness, and the explosion has no direction, which inevitably causes great damage to the casing.

[0004] In mechanical shaping, pear-shaped device expansion technology, casing grinding and milling technology, eccentric roller shaping technology, rotary shock technology, ball shaping technology, etc., generally exist damage to the casing, sacrifice the thickness of the casing, and it is difficult to restore the original diameter. Long cycle, large investment and other issues

[0005] The common characteristics of explosive plastic surgery and mechanical plastic surgery are that it cannot be repaired continuously, the repair efficiency is low, and it is uncontrollable.
