Description

TECHNICAL FIELD

[0001] The utility model relates to positioning device technical field, concretely relates to double metal composite pipe fixed distance positioning device. BACKGROUND

[0002] With the development of oil and gas exploitation and transportation to the ocean, deep well and other high corrosion environment, due to the high content of CO2, H2S and other corrosive substances in oil and gas field, great economic loss and accident caused by pipeline corrosion often occur. First, the oil pipe of water injection well is seriously scaled and corroded; second, the ground technical pipeline is corroded, scaled and perforated; third, the downhole pipe rod is eccentrically ground and corroded, and a large number of pipe rods are scrapped; fourth, the existing lining and coating pipe cannot resist high temperature, and the corrosion and eccentric grinding of deep well section cannot be solved. Therefore, how to improve the corrosion resistance of steel pipe is one of the important topics in the current steel pipe industry research.

[0003] The double metal composite pipe is composed of two metal pipes with different materials, one pipe is inside and mainly bears corrosion, and the other pipe is outside and is used for strength support. The pipes are tightly combined through various deformation and connection technologies. The double metal composite pipe can maximize the complementary advantages of materials, save alloy elements, reduce engineering cost, improve the corrosion resistance and wear resistance of the pipeline, and prolong the service life of the pipeline on the basis of ensuring the performance of the original base pipe. It is a substitute product of pure stainless steel pipe, copper pipe or other corrosion-resistant alloy pipe.

[0005] Therefore, a lining stainless steel double metal composite pipe hydraulic expansion pipe preparation process and a set of booster system are developed. Multiple elastic expansion bags are used for expansion, and multiple composite pipes can be simultaneously subjected to booster expansion process, so that the lining stainless steel pipe is expanded and tightly combined with the outer layer base pipe to form a new type of composite pipe.

[0016] As an optimized scheme, the fixed-distance table is provided with a fixed-distance installation groove, the fixed-distance claw comprises a pressing plate hingedly connected in the fixed-distance installation groove, a baffle is vertically fixedly connected with the hinged end of the pressing plate, the weight of the baffle is greater than that of the pressing plate, the baffle is located in the fixed-distance installation groove in normal state, and the pressing plate extends out of the fixed-distance installation groove.

[0017] As an optimization scheme, the side wall of the pressing plate is fixed with a limiting plate, and the lower end of the limiting plate abuts against the upper edge of the distance installation groove in normal state.

[0018] As an optimization scheme, when the steel pipe presses the pressing plate, the pressing plate is located in the distance installation groove, and the baffle extends from the distance installation groove.

[0019] As an optimization scheme, the distance table is vertically fixed with a positioning column at the top of one end close to the pressing plate.

[0020] As an optimization scheme, the base is fixed with a C-shaped guide frame corresponding to the two ends of the distance table, and the end of the distance table is in frictional contact with the inner wall of the guide frame.

[0024] The steel pipe supporting table can support the steel pipe, the first lifting cylinder drives the positioning table to descend to the area below the steel pipe supporting table, the second lifting cylinder drives the distance table to ascend, so that the distance claw is located above the steel pipe supporting table, the steel pipe is unloaded from the carriage on one side of the base, and the steel pipe can automatically roll along the steel pipe supporting table to the side with lower height under the inclined guiding action due to the slight inclination of the base. Since the weight of the baffle is greater than the weight of the pressing plate in normal state, the baffle is located in the distance installation groove, and the pressing plate extends from the distance installation groove, the rolling steel pipe can press the pressing plate in turn, move to the lower side of the steel pipe supporting table, and the distance table is vertically fixed with a positioning column at the top of one end close to the pressing plate, so that the first rolling steel pipe is positioned when abutting against the positioning column, and the subsequent steel pipes are positioned in the area between two adjacent distance claws. Since the positioning clamps of the positioning table correspond to the distance claws, the first lifting cylinder drives the positioning table to ascend, and then the driving cylinder drives the positioning claw to close, so that the steel pipe is accurately positioned, the automatic positioning of the plurality of steel pipes is realized, the operation of the operator is saved, and the production efficiency of the bimetallic composite pipe is improved.

[0025] After the pressure is applied to the steel pipe, when the steel pipe is unloaded, the positioning claw first releases its positioning on the steel pipe, the first lifting cylinder drives the positioning claw to descend, and then the second lifting cylinder drives the distance platform to descend. The positioning column follows the distance platform to descend and releases the limit on the end of the steel pipe. Under the action of the inclined steel pipe support platform, the steel pipe automatically rolls down to complete the automatic unloading, which is convenient and fast. Attached Figure Description
