Embodiment 1

[0049]Such asfigure 1 As shown, the present invention discloses a pipe liner internal counterpart system, including a fuselage system 1, a cone system 2, and also a flexible connecting system 3; the flexible connecting system 3 includes a connecting machine The universal joint 31 of the body system (1) and the cone system 2.

[0050]In this solution, the flexible connection system 3 is set to change the rigid connection method of the traditional pipe liner, and the fuselage system 1 and the cone system 2 are connected through the flexible connection system 3 to realize the fuselage system 1 and the cone system The flexible connection of 2, through the setting of flexible connection system 3, allows the position and angle of the cone system 2 relative to the fuselage system 1, which greatly improves the accuracy of the alignment and the coaxiality of the cone system and the steel pipe after the alignment. The service life problem caused by the rigid connection of the cone system 2 and t...

Embodiment 2

[0052]Such asFigure 2-5 As shown, on the basis of Example 1, the present invention is further limited.

[0053]The flexible connecting system 3 further includes a first elastic connecting member 32, a connecting plate 33, and at least two front wheel flexible systems 34; the universal joint 31 is connected to the cone system 2 through the connecting plate 33; the first elastic connecting member 32 One end is connected to the connecting plate 33, and the other end is connected to the fuselage system 1. The arrangement of the connecting plate 33 and the first elastic connecting member 32 further ensures the flexible connection strength of the fuselage system 1 and the cone system 2; The arrangement of the connecting piece 32, due to the elasticity of the first elastic connecting piece 32, ensures that the position and angle deviation of the cone system 2 and the fuselage system 1 due to the pipe shape can be under the elastic action of the first elastic connecting piece 32 The quick reco...

Embodiment 3

[0062]Such asFigure 6-10 As shown, on the basis of Example 1, the present invention is further limited.

[0063]The cone system 2 includes a first expansion cylinder 21, a second expansion cylinder 22, and a gasket 23; the first expansion cylinder 21 and the second expansion cylinder 22 can be pressed against the inner surface of the pipe under the action of expansion force; The first expansion cylinder 21 is closer to the fuselage system than the second expansion cylinder 22. By arranging the first expansion cylinder 21 and the second expansion cylinder 22, the relative positions of the two pipes during pipe welding are ensured. In the pipeline welding type, the top of the first expansion cylinder 21 contacts the inner surface of one of the pipes to be welded. The second expansion cylinder top 22 extends to contact the inner surface of another pipe to be welded to realize the connection between the welded pipes; the gasket 23 is arranged between the first expansion cylinder 21 and the...

Abstract

The invention discloses a pipeline liner internal aligning device system. The pipeline liner internal aligning device system comprises a machine body system and a conical head system and further comprises a flexible connection system; and the flexible connection system comprises a universal joint used for connecting the machine body system and the conical head system and a first elastic connectionpiece used for supporting the machine body system. The flexible connection system is arranged, the rigid connection mode of a traditional pipeline liner internal aligning device is changed, the machine body system and the conical head system are connected through the flexible connection system, and flexible connection of the machine body system and the conical head system is achieved; and throughthe structural design of the pipeline liner internal aligning device system, the aligning precision and the coaxiality between the aligned conical head system and a steel pipe are greatly improved, and the problems that an aligning device is short in service life, long in auxiliary aligning time and low in aligning precision, and copper seeping exists in the welding process are solved.

Description

Technical field[0001]The invention relates to the technical field of pipeline construction, in particular to a pipe liner inner pairing device system.Background technique[0002]With the automatic welding of long-distance pipeline welding, the gradual application of intelligent products and design concepts in the welding industry of long-distance oil and natural gas pipelines, the demand for the bottoming, filling, and covering process of the pipeline gasket and the outer welding groove There is also an increasing need for efficient and precise control schemes.[0003]The traditional pipe liner inner pairing device is actually realized by the traditional inner pairing device plus the pad structure that moves with the expansion claw. In actual work, the traditional pipe liner inner pairing device often causes the machine to be machined during the matching process due to the pipe structure. The body system and the cone system are different in axis, which seriously affects the service life...
