[0042] like Figure 1 and Figure 2 As shown, according to an embodiment of the utility model, a pipeline compensator 100 is proposed, which includes a first pipe body 10, a second pipe body 20 and a connecting assembly 30. The first pipe body 10 includes a first end and a second end arranged oppositely, and the first end is used to be connected to the pipe to be connected on one side. The second pipe body 20 includes a third end and a fourth end arranged oppositely, and the third end is used to be connected to the pipe to be connected on the other side. The connecting assembly 30 includes a bellows 32 and a hinge mechanism 31. The bellows 32 is respectively connected to the second end and the fourth end. The hinge mechanism 31 is respectively connected to the first pipe body 10 and the second pipe body 20. The hinge mechanism 31 has a preset rotation stroke and a preset movement stroke. Within the preset rotation stroke, the angle between the first pipe body 10 and the second pipe body 20 is adjustable. Within the preset movement stroke, the axial distance between the first pipe body 10 and the second pipe body 20 is adjustable.

[0043] Specifically, the connection assembly 30 connects the first tube body 10 and the second tube body 20 together, wherein the bellows 32 of the connection assembly 30 connects the first tube body 10 and the second tube body 20, and the hinge assembly movably connects the first tube body 10 and the second tube body 20. Within the range of the preset rotation stroke, the first tube body 10 can rotate relative to the second tube body 20, so that the angle between the two changes, thereby achieving adjustment in the angular direction (angular direction), so that the angular displacement of the pipeline connection position is supplemented, and within the range of the preset movement stroke, the first tube body 10 can move axially relative to the second tube body 20, so that the distance between the first tube body 10 and the second tube body 20 changes, thereby achieving adjustment in the axial direction, so that the axial displacement of the pipeline connection position is supplemented.

[0044] It should be understood that the two ends of the bellows 32 are respectively connected to the first tube body 10 and the second tube body 20, and the first tube body 10 is connected to the second tube body 20 through the bellows 32. When the first tube body 10 changes its angle relative to the second tube body 20 within a preset rotation stroke, the bellows 32 deforms to adapt to the angle change between the first tube body 10 and the second tube body 20. In addition, when the first tube body 10 moves relative to the second tube body 20 within a preset moving stroke, the bellows 32 also deforms to adapt to the position change between the first tube body 10 and the second tube body 20.

[0045] When the compensator is used for the pipeline connection position, the first pipe body 10 is connected to the pipeline to be connected on one side of the pipeline connection position, and the second pipe body 20 is connected to the pipeline to be connected on the other side of the pipeline connection position. The connecting component 30 can adjust the connection angle between the first pipe body 10 and the second pipe body 20. At the same time, the connecting component 30 can also adjust the axial distance between the first pipe body 10 and the second pipe body 20. The pipeline compensator 100 is used to realize the angular and axial deformation compensation of the pipeline connection position, thereby meeting the use requirements of the pipeline connection.

[0046] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the hinge mechanism 31 includes a first plate body 311, a second plate body 312 and a pin shaft 33. One end of the first plate body 311 is connected to the first tube body 10. A first long hole is opened on the first plate body 311. The length direction of the first long hole is consistent with the axial direction of the first tube body 10. One end of the second plate body 312 is connected to the second tube body 20. A second long hole 3123 is opened on the second plate body 312. The length direction of the second long hole 3123 is consistent with the axial direction of the second tube body 20. Along the radial direction of the second tube body 20, the other end of the second plate body 312 is arranged on one side or both sides of the other end of the first plate body 311. At least part of the second long hole 3123 is overlapped with at least part of the first long hole. The pin shaft 33 is respectively penetrated in the first long hole and the second long hole 3123. Within a preset rotation stroke, the first plate body 311 can rotate relative to the second plate body 312 around the pin shaft 33. Within a preset moving stroke, the first plate body 311 can move relative to the second plate body 312.

[0047] Specifically, the first long hole on the first plate body 311 is extended along the axial direction of the first tube body 10, and the second long hole 3123 on the second plate body 312 is extended along the axial direction of the second tube body 20. Along the radial direction of the first tube body 10 or the second tube body 20, the first plate body 311 and the second plate body 312 are stacked, and along the radial direction of the first tube body 10 or the second tube body 20, the first long hole and the second long hole 3123 are connected (that is, a small part of the second long hole 3123 is overlapped with at least a part of the first long hole), and the pin shaft 33 is arranged through the first long hole and the second long hole 3123.

[0048] When the first tube body 10 and the second tube body 20 need to rotate, the first tube body 10 with the first plate body 311 and the second tube body 20 with the second plate body 312 rotate relative to the pin shaft 33 respectively to adjust the angle between the first tube body 10 and the second tube body 20.

[0049] When the axial position of the first tube body 10 and the second tube body 20 needs to be adjusted, the first tube body 10 with the first plate body 311 and the second tube body 20 with the second plate body 312 respectively move relative to the pin shaft 33, and the positions of the pin shaft 33 in the first long hole and the pin shaft 33 in the second long hole 3123 change, thereby realizing the position adjustment between the first tube body 10 and the second tube body 20.

[0050] It should be pointed out that, in the present application, the specifications of the first long hole and the second long hole 3123 are the same.

[0051] The pin shaft 33 includes a shaft body, a first limit piece and a second limit piece, the shaft body is respectively inserted into the first long hole and the second long hole 3123, the first limit piece is connected to one end of the pin shaft 33 and is located on the outside of the first long hole, the second limit piece is connected to the other end of the pin shaft 33 and is located on the outside of the second long hole 3123, wherein the first limit piece and the second limit piece cannot pass through the first long hole and the second long hole 3123, so that the shaft body remains in the first long hole and the second long hole 3123.

[0052] In addition, in the present application, the value of the preset rotation stroke angle is between -45° and 45°, and the value of the preset movement stroke is between 1 cm and 50 cm.

[0053] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the second plate body 312 includes a first part 3121 and a second part 3122. Along the radial direction of the second tube body 20, the first part 3121 and the second part 3122 are respectively arranged on the opposite sides of the first plate body 311, and the first part 3121 and the second part 3122 are respectively provided with a second long hole 3123, and the second long hole 3123 located on the first part 3121 is arranged opposite to the second long hole 3123 located on the second part 3122.

[0054] Specifically, the second plate body 312 is configured as a first part 3121 and a second part 3122, and by respectively arranging the first part 3121 and the second part 3122 on opposite sides of the first plate body 311, the contact area between the first plate body 311 and the second plate body 312 is increased, so that the structural stability formed between the first plate body 311 and the second plate body 312 is enhanced.

[0055] In addition, the first part 3121 and the second part 3122 are respectively arranged on opposite sides of the first plate body 311. The first part 3121 and the second part 3122 can be used to limit the first plate body 311 on opposite sides of the first plate body 311, thereby reducing the movement of the first plate body 311 and improving the accuracy of position adjustment.

[0056] In some embodiments of the utility model, a first limit member and a second limit member are provided on the second plate body 312, and the first limit member and the second limit member are spaced apart along the circumferential direction of the pin shaft 33. The other end of the first plate body 311 can respectively abut against the first limit member and the second limit member, and along the circumferential direction of the pin shaft 33, the distance between the first limit member and the second limit member is a preset rotation stroke.

[0057] Specifically, by providing the first limiter and the second limiter, when the other end of the first plate 311 abuts against the first limiter, the rotation of the first tube 10 relative to the second tube 20 reaches the maximum position in the direction, and when the other end of the first plate 311 abuts against the second limiter, the rotation of the first tube 10 relative to the second tube 20 reaches the maximum position in the direction. In the present application, the first limiter and the second limiter are used to limit the rotation stroke of the first plate 311 respectively, so that the rotation range of the first tube 10 relative to the second tube 20 is controllable, which improves the convenience during use.

[0058] In some embodiments of the present invention, Figure 1 As shown, a first connecting plate 11 is disposed on the first tube body 10 , and the first plate body 311 is fixedly connected to the first connecting plate 11 .

[0059] Specifically, the first connecting plate 11 is arranged around the first tube body 10, and the first connecting plate 11 is extended in the radial direction of the first tube body 10, and the first plate body 311 is extended in the axial direction of the first tube body 10 and is vertically connected to the first connecting plate 11, wherein the connection method between the first plate body 311 and the first connecting plate 11 is welding, thereby ensuring the fixing strength of the first plate body 311 and improving the structural stability of the first plate body 311.

[0060] In some embodiments of the present invention, Figure 1 As shown, the second tube body 20 is provided with a second connecting plate 21 , and the second plate body 312 is fixedly connected to the second connecting plate 21 .

[0061] Specifically, the second connecting plate 21 is arranged around the second tube body 20, and the second connecting plate 21 is extended in the radial direction of the second tube body 20, and the second plate body 312 is extended in the axial direction of the second tube body 20 and is vertically connected to the second connecting plate 21, wherein the connection method between the second plate body 312 and the second connecting plate 21 is welding, thereby ensuring the fixing strength of the second plate body 312 and improving the structural stability of the second plate body 312.

[0062] In some embodiments of the present invention, Figure 1 As shown, the second end is provided with a first plug-in groove 12, the first plug-in groove 12 is arranged radially outside the second end, and one end of the bellows 32 is plugged into the first plug-in groove 12. Specifically, the bellows 32 and the first plug-in groove 12 are plug-fitted, so as to improve the sealing effect of the connection position and reduce the leakage of the connection position.

[0063] In addition, a sealing structure may be provided between the bellows 32 and the first plug-in slot 12 , such as a sealing ring or a sealing adhesive.

[0064] In some embodiments of the present invention, Figure 1 As shown, the fourth end is provided with a second plug-in groove 22, which is arranged radially outside the fourth end, and the other end of the bellows 32 is plugged into the second plug-in groove 22. Specifically, the bellows 32 and the second plug-in groove 22 are plug-fitted, thereby improving the sealing effect of the connection position and reducing leakage at the connection position.

[0065] In addition, a sealing structure may be provided between the bellows 32 and the second plug-in slot 22 , such as a sealing ring or a sealing adhesive.

[0066] In some embodiments of the present invention, Figure 1As shown, the connection assembly 30 further includes a sealing ring 33, and the sealing ring 33 seals the area between the second end and the fourth end. Specifically, by providing the sealing ring 33, the area between the first tube body 10 and the second tube body 20 can be separated from the bellows 32, thereby reducing the leakage at the position of the bellows 32.

[0067] In some embodiments of the present invention, Figure 1 As shown, the pipe compensator 100 further includes a band ring 40, and the band ring 40 is sleeved on the radial outer side of at least one of the first end and the third end. Specifically, by sleeved on the radial outer side of at least one of the first end and the third end, the band ring 40 can be used to adjust and compensate for the on-site axial error, which brings convenience to the on-site welding of the large-diameter compensator and the construction pipeline.

[0068] In addition, the connection method between the wrapping ring 40 and the pipe to be connected is socket welding, and the socket angle welding method is used to adjust the length error of the on-site pipe. In this way, when welding, there is no need to add a section to make up for a short section, nor is there a need to cut off a section because it is too long, which improves the convenience of the pipeline connection process.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
