[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0024] Refer to Figures 1 to 3 , which shows the preferred structure of the pipe clamping connection centering device provided by an embodiment of the present invention. As shown in the figure, the device includes: an operation platform 1, a fixed pipe support mechanism 2, a fixed pipe clamping mechanism 3, a wet cleaning mechanism 4, a movable pipe clamping mechanism 5, and a movable pipe support mechanism 6; wherein,

[0025] The fixed pipe support mechanism 2, the fixed pipe clamping mechanism 3, the wet cleaning mechanism 4, the movable pipe clamping mechanism 5, and the movable pipe support mechanism 6 are arranged in sequence along the transverse direction on the operation platform 1. Specifically, the transverse direction can be the length direction of the operation platform 1 (such as Figure 2 the horizontal direction shown), and the fixed pipe support mechanism 2, the fixed pipe clamping mechanism 3, the wet cleaning mechanism 4, the movable pipe clamping mechanism 5, and the movable pipe support mechanism 6 are also arranged along the longitudinal direction, that is, the width direction of the operation platform 1 (such as Figure 2 the vertical direction shown), so that the movable end pipe and the fixed end pipe can both be arranged along the length direction of the operation platform 1, that is, the movable end pipe and the fixed end pipe are arranged horizontally in Figure 2 .

[0026] The fixed pipe support mechanism 2 is used to support the fixed-end pipe. Specifically, the fixed pipe support mechanism 2 can support the fixed-end pipe movably so that the fixed-end pipe can move laterally on the fixed pipe support mechanism 2 to the fixed pipe clamping mechanism 3.

[0027] The fixed pipe clamping mechanism 3 is used to centeringly clamp the fixed-end pipe so that the fixed-end pipe is arranged on the fixed pipe support mechanism 2 and the fixed pipe clamping mechanism 3. Specifically, the fixed pipe clamping mechanism 3 can centeringly and fixedly clamp the fixed-end pipe, that is, gradually clamp the fixed-end pipe from both sides to ensure that the axis of the fixed-end pipe is arranged laterally and to avoid the movement of the fixed-end pipe, such as rotation or movement. That is, through the fixed pipe support mechanism 2 and the fixed pipe clamping mechanism 3, the fixed-end pipe is supported and clamped at two positions, which can ensure the stability of the fixed-end pipe. In this embodiment, the fixed pipe clamping mechanism 3 and the fixed pipe support mechanism 2 can be arranged at intervals to further ensure the stability of the fixed-end pipe.

Moreover, the movable end pipe is coaxially centered with the fixed end pipe so that the movable end pipe gradually approaches the pipe joint along its axial direction. During the movement, the wet cleaning mechanism 4 wets and cleans the outer wall of the movable end pipe so that the end of the movable end pipe can be inserted into the pipe joint after cleaning, realizing the crimping connection. Specifically, the movable pipe clamping mechanism 5 can centeringly clamp the movable end pipe, that is, gradually clamp the movable end pipe from both sides to ensure that the axial direction of the movable end pipe is arranged horizontally, so as to ensure coaxial setting between the movable end pipe and the fixed end pipe, that is, realize the centering between the two. At the same time, the movable pipe clamping mechanism 5 clamps the movable end pipe movably so that the movable end pipe can be arranged on the movable pipe support mechanism 6, the movable pipe clamping mechanism 5, and the wet cleaning mechanism 4 in a way that it can move along its axial direction, so that the movable end pipe can pass through the movable pipe support mechanism 6, the movable pipe clamping mechanism 5, and the wet cleaning mechanism 4 and gradually approach the fixed end pipe for movement to be inserted into the pipe joint. During the insertion process, the end of the movable end pipe is wetted and cleaned and the two ends of the pipe are kept in a straight line, avoiding damage or detachment of the internal sealing ring of the pipe joint, improving the qualification rate of the connection of thin-walled stainless steel pipe joints, reducing the situation of rework and repair, and ensuring the quality of pipeline construction.

A plurality of corresponding clamping holes 1113 are provided on both the fixed section 1111 and the sliding section 1112, and the fixed section 1111 and the first-level sliding section 1112 are connected by a clamping member passing through the clamping holes 1113, and / or, any two adjacent sliding sections 1112 are connected by a clamping member passing through the clamping holes 1113. Among them, a plurality of clamping holes 1113 are provided along the length direction at the sliding end of the fixed section 1111 and at both ends of the sliding section 1112.

Of course, the sliding sections 1112 can also be adjusted in this way. Or, there is one clamping hole 1113 at the sliding end of the fixed section 1111, one clamping hole 1113 at one end of the sliding section 1112, and a plurality of clamping holes 1113 at the other end.

Among them, the clamping member can be a bolt, and the height of the support leg can be adjusted by the clamping hole 1113 in cooperation with the connecting bolt.

[0036] In other embodiments, the bottom end of the height adjusting member 11 can also be provided with moving wheels to realize the movement of the device; of course, in another embodiment, moving wheels (not shown in the figure) can also be provided under the platform body 12. By retracting the height adjusting member 11, the moving wheels can be made to contact the ground for movement, and by extending the height adjusting member 11, the moving wheels can be arranged at an interval from the ground for fixed support.

[0038] Specifically, the support base 21 may include a bottom support 211 and a top support 212. The bottom support 211 and the top support 212 may be an integral structure. The bottom support 211 can be fixed on the platform body 12 through fixing bolts. An arc-shaped groove is provided at the top of the top support 212, and the top wall has an arc surface structure, and its arc surface structure can be adapted to the outer wall of the fixed-end pipe. A plurality of balls 22 are uniformly arranged on the arc surface structure for supporting the free movement of the fixed-end pipe in the axial direction and reducing the friction of the fixed-end pipe moving in the axial direction.

[0040] Specifically, the first driving member 33 may be a manual rocker.

At the reserved pipe processing operation area in the middle area between the fixed pipe support mechanism 2 and the fixed pipe clamping mechanism 3, insert the pipe joint, i.e., the connecting joint, onto the end of the fixed-end pipe. Then, place the movable-end pipe on the top support of the movable pipe support mechanism 6, and manually and slowly push the movable-end pipe into it, so that it passes through the movable pipe clamping mechanism 5 between the two centering movable rollers 54, and passes through the wet cleaning mechanism 4 from the pipe installation hole 431, and the end part is inserted into the pipe joint arranged on the end of the fixed-end pipe.
