[0047] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0048] The embodiment of the present application provides a welding device for a pipe reinforcement sleeve 20, such as Figures 1 to 6 As shown, the pipe reinforcement sleeve 20 assembly welding device of this embodiment includes:

[0049] Assemble and weld the bracket 100;

[0050] The first pipe clamp positioning unit 200 includes a first pipe clamp fixing frame 210 disposed on the assembly welding bracket 100 and a first swing arm 220 hinged at one end to the first pipe clamp fixing frame 210, and the first swing arm 220 swings relative to the first pipe clamp fixing frame 210 to form a first annular pipe clamp with the first pipe clamp fixing frame 210;

[0052] The sleeve adsorption assembly unit 600 includes a first sleeve adsorption assembly 610 disposed on the first semicircular gear 530 and a second sleeve adsorption assembly 620 disposed on the second semicircular gear 550; and,

[0054] The pipeline reinforcement sleeve 20 assembly welding device of the present embodiment has a first pipe clamping positioning unit 200 for positioning and fixing the pipeline reinforcement sleeve 20 assembly welding device on the conveying pipeline, and then the pipeline reinforcement sleeve 20 is adsorbed by the sleeve adsorption assembly unit 600, and the pipeline reinforcement sleeve 20 is rotated to a preset position by the sleeve rotation unit 500, and finally the weld of the pipeline reinforcement sleeve 20 is welded by the welding unit 700, thereby realizing automatic assembly, positioning and welding of the pipeline reinforcement sleeve 20, changing the current situation that the pipeline reinforcement sleeve 20 needs manual assembly and welding, and the welding cladding amount is greatly reduced compared with manual welding, which reduces the welding difficulty while improving the welding efficiency, thereby improving the welding construction efficiency of the oil and gas pipeline maintenance and emergency repair.

[0055] Furthermore, the installation process and welding quality of the pipe reinforcement sleeve 20 will have a decisive impact on the final construction quality. The pipe reinforcement sleeve 20 group welding device of this embodiment can improve the welding efficiency while ensuring the welding quality to ensure the construction quality.

[0056] In the pipe reinforcement sleeve 20 group welding device of this embodiment, the main function of the group welding bracket 100 is to connect the units of the pipe reinforcement sleeve 20 group welding device together, and play a supporting and bridging role. The specific structure of the group welding bracket 100 is adaptively adjusted according to the structure and relative position of each unit. Figures 1 to 3 As shown, in this embodiment, the first tube clamping positioning unit 200, the sleeve rotating unit 500 and the welding unit 700 are directly provided on the assembly welding bracket 100, and the sleeve adsorption assembly unit 600 is indirectly provided on the assembly welding bracket 100 through the sleeve rotating unit 500.

[0057] In the pipe reinforcement sleeve 20 assembly welding device of the present embodiment, the first pipe clamping and positioning unit 200 includes a first pipe clamping and fixing frame 210 and a first swing arm 220 hinged to the first pipe clamping and fixing frame 210. The first swing arm 220 swings relative to the first pipe clamping and fixing frame 210 to form a first annular pipe clamp that can be opened and closed, so that the pipe can be clamped on the conveying pipe by the first annular pipe clamp. In the present embodiment, the first pipe clamping and fixing frame 210 can be half-wound on the conveying flow channel 10 by swinging the first swing arm 220 open, and then the first pipe clamping and positioning unit 200 can be clamped on the conveying pipe by closing the first swing arm 220, that is, the sleeve rotating unit 500, the sleeve adsorption assembly unit 600 and the welding unit 700 of the pipe reinforcement sleeve 20 assembly welding device are directly or indirectly connected to the first pipe clamping and positioning unit 200 through the assembly welding bracket 100 and fixed on the conveying pipe, so that the pipe reinforcement sleeve 20 assembly welding device is clamped and fixed on the conveying pipe as a whole. In this embodiment, the first pipe clamp fixing frame 210

[0058] In the pipe reinforcement sleeve 20 assembly welding device of the present embodiment, the sleeve rotating unit 500 includes a crossbeam 510 and a first gear mounting plate 520 and a second gear mounting plate 540 movably arranged on the crossbeam 510. The first gear mounting plate 520 and the second gear mounting plate 540 can move toward and away from each other on the crossbeam 510, and at the same time drive the first semicircular gear 530 arranged on the first gear mounting plate 520 and the second semicircular gear 550 on the second gear mounting plate 540 to move toward and away from each other synchronously; after the first semicircular gear 530 and the second semicircular gear 550 move away from each other, there is a gap between the first semicircular gear 530 and the second semicircular gear 550. The open space can accommodate the conveying pipe and the pipe reinforcement sleeve 20, so that the sleeve rotation unit 500 can be mounted on the conveying pipe; after the first semicircular gear 530 and the second semicircular gear 550 move toward each other and approach each other, the first semicircular gear 530 and the second semicircular gear 550 are closed to form a circular gear, and the circular gear is wound around the conveying pipe and is coaxial with the first annular pipe clamp; at the same time, the first semicircular gear 530 is rotatably arranged on the first gear mounting plate 520, and the second semicircular gear 550 is rotatably arranged on the second gear mounting plate 540. After the first semicircular gear 530 and the second semicircular gear 550 are closed to form a circular gear, the circular gear can rotate as a whole. Correspondingly, the sleeve adsorption assembly pair unit 600 includes a first sleeve adsorption assembly 610 arranged on the first semicircular gear 530 and a second sleeve adsorption assembly 620 arranged on the second semicircular gear 550. Therefore, when the first semicircular gear 530 and the second semicircular gear 550 are closed to form a circular gear and rotate as a whole, the first sleeve adsorption assembly 610 and the second sleeve adsorption assembly 620 can rotate synchronously with the circular gear, that is, the first sleeve adsorption assembly 610 and the second sleeve adsorption assembly 620 can rotate around the conveying pipeline. After the cylinder adsorption assembly 610 and / or the second sleeve adsorption assembly 620 adsorb the semicircular structure of the pipe reinforcement sleeve 20, the semicircular structure of the pipe reinforcement sleeve 20 can be driven to rotate synchronously around the conveying pipe, so that the two adsorbed semicircular structures of the pipe reinforcement sleeve 20 can be paired, that is, the adsorption and pairing of the semicircular structure of the pipe reinforcement sleeve 20 are realized through the sleeve adsorption pairing unit 600, and at the same time, the adsorption, pairing and rotation of the semicircular structure of the pipe reinforcement sleeve 20 are realized through the sleeve adsorption pairing unit 600 and the sleeve rotation unit 500.

[0059] In the pipe reinforcement sleeve 20 assembly welding device of this embodiment, the welding unit 700 includes a welder 720 disposed on the assembly welding bracket 100 and a welding gun 710 connected to the welder 720, and the welding gun 710 can move in three-dimensional space relative to the assembly welding bracket 100. Since the welding gun 710 can move in three-dimensional space relative to the assembly welding bracket 100, when the semicircular structure of the adsorbed pipe reinforcement sleeve 20 is assembled, the welding gun 710 can be moved to the transverse weld of the semicircular structure of the pipe reinforcement sleeve 20, and can move along the transverse weld to perform welding.

[0060] In the pipe reinforcement sleeve 20 assembly welding device of the present embodiment, the assembly welding bracket 100, the first pipe clamping positioning unit 200, the sleeve rotation unit 500, and the sleeve adsorption assembly unit 600 are all symmetrical with respect to the vertical plane of the axis of the conveying pipeline, that is, the pipe reinforcement sleeve 20 assembly welding device as a whole is symmetrical with respect to the vertical plane of the axis of the conveying pipeline.

[0061] Optionally, in the pipe reinforcement sleeve 20 assembly welding device of the present embodiment, the welding groove of the pipe reinforcement sleeve 20 is a narrow gap U-shaped groove or a narrow gap V-shaped groove for automatic pipe welding.

[0064] The pipe clamp positioning connection unit 400 is disposed between the first pipe clamp fixing frame 210 and the second pipe clamp fixing frame 310 so that the first annular pipe clamp and the second annular pipe clamp are coaxial.

[0065] In this embodiment, if Figures 1 to 3 As shown, the second tube clamping positioning unit 300 has the same setting principle as the first tube clamping positioning unit 200, and includes a second tube clamping fixing frame 310 and a second swing arm 320 hinged to the second tube clamping fixing frame 310. The second swing arm 320 swings relative to the second tube clamping fixing frame 310 to form a second annular tube clamp that can be opened and closed, so that the second annular tube clamp can be clamped on the conveying pipe; in this embodiment, the second tube clamping fixing frame 310 can be half-wrapped around the conveying flow channel 10 by swinging open the second swing arm 320, and then the second tube clamping positioning unit 300 can be clamped on the conveying pipe by closing the second swing arm 320.

[0066] At the same time, a pipe clamping positioning connection unit 400 is provided between the first pipe clamping fixing frame 210 and the second pipe clamping fixing frame 310, so that the first pipe clamping fixing frame 210 and the second pipe clamping fixing frame 310 form a rigid whole through the pipe clamping positioning connection unit 400, and at the same time, the first annular pipe clamp formed by the first pipe clamping positioning unit 200 and the second annular pipe clamp formed by the second pipe clamping positioning unit 300 are coaxial. Therefore, the pipe reinforcement sleeve 20 group welding device of this embodiment can be fixed on the conveying pipe through the first pipe clamping positioning unit 200 and the second pipe clamping positioning unit 300, and under the joint fixing action of the first pipe clamping positioning unit 200 and the second pipe clamping positioning unit 300, not only the pipe reinforcement sleeve 20 group welding device is fixed on the conveying pipe more firmly, but also the coaxiality of the pipe reinforcement sleeve 20 group welding device relative to the conveying pipe can be ensured to remain unchanged.

[0067] In this embodiment, the tube clamping positioning connection unit 400 may optionally include four tube clamping positioning connection rods, such as Figures 1 to 3 As shown, four tube clamp positioning connecting rods are symmetrically connected between the first tube clamp fixing frame 210 and the second tube clamp fixing frame 310, so that the first tube clamp fixing frame 210 and the second tube clamp fixing frame 310 are parallel to each other and the distance is stable, so as to ensure that the coaxiality of the first annular tube clamp in the first tube clamp positioning unit 200 and the second annular tube clamp in the second tube clamp positioning unit 300 remains unchanged.

[0068] In this embodiment, the sleeve rotation unit 500, the first tube clamping positioning unit 200, and the second tube clamping positioning unit 300 are coaxial with the axis of the conveying pipeline and are arranged in sequence and are axially symmetrical relative to the conveying pipeline, wherein the sleeve rotation unit 500 and the first tube clamping positioning unit 200 are fixedly connected by a group welding bracket 100, the first tube clamping fixing frame 210 in the first tube clamping positioning unit 200 and the second tube clamping fixing frame 310 in the second tube clamping positioning unit 300 are fixedly connected by a tube clamping positioning connection unit 400, the sleeve adsorption assembly in the sleeve adsorption assembly unit 600 is divided into two groups, which are symmetrically installed on the first semicircular gear 530 and the second semicircular gear 550 in the sleeve rotation unit 500, and the welding unit 700 is installed on the group welding bracket 100.

[0069] As an optional implementation, Figures 1 to 4 As shown, the first tube clamping positioning unit 200 of this embodiment also includes at least three first tube clamping positioning members 230 which are arranged on the inner wall of the first annular tube clamp and can be synchronously extended and retracted; the second tube clamping positioning unit 300 also includes at least three second tube clamping positioning members 330 which are arranged on the inner wall of the second annular tube clamp and can be synchronously extended and retracted.

[0070] In this embodiment, if Figures 1 to 4As shown, at least three synchronously retractable first tube clamp positioning members 230 are arranged on the inner wall of the first annular tube clamp, that is, the inner diameter of the first annular tube clamp can be adjusted by synchronously retracting the first tube clamp positioning members 230, so that the first tube clamp positioning unit 200 can adjust the inner diameter of the first annular tube clamp according to the outer diameter of the conveying pipe, so that the inner diameter of the first annular tube clamp matches the outer diameter of the conveying pipe, and at the same time, the synchronous retracting of the first tube clamp positioning members 230 can ensure the concentric positioning of the first annular tube clamp and the conveying pipe.

[0071] In this embodiment, if Figures 1 to 4 As shown, when the pipe reinforcing sleeve 20 group welding device is provided with the first pipe clamping positioning unit 200 and the second pipe clamping positioning unit 300 at the same time, the setting principle is the same as that of the first pipe clamping positioning member 230 in the first pipe clamping positioning unit 200, and at least three second pipe clamping positioning members 330 that can be synchronously retracted are provided on the inner wall of the second annular pipe clamp, that is, the inner diameter of the second annular pipe clamp can be adjusted by the synchronous retraction of the second pipe clamping positioning members 330, so that the second pipe clamping positioning unit 300 can adjust the inner diameter of the second annular pipe clamp according to the outer diameter of the conveying pipe, so that the inner diameter of the second annular pipe clamp matches the outer diameter of the conveying pipe, and at the same time, the concentric positioning of the second annular pipe clamp, the circular gear and the conveying pipe can be ensured by the synchronous retraction of the second pipe clamping positioning members 330; further, in order to ensure the concentric positioning of the first annular pipe clamp and the second annular pipe clamp, the first pipe clamping positioning member 230 and the second pipe clamping positioning member 330 also need to be synchronously retracted.

[0072] In this embodiment, if Figures 1 to 4 As shown, in order to ensure the concentric positioning of the first annular pipe clamp, the second annular pipe clamp and the conveying pipe, the first pipe clamp positioning members 230 are evenly distributed on the inner side wall of the first annular pipe clamp, and the second pipe clamp positioning members 330 are evenly distributed on the inner side wall of the second annular pipe clamp.

[0073] As an optional implementation, the first pipe clamping fixing frame 210 and / or the second pipe clamping fixing frame 310 is provided with a sleeve push rod parallel to the central axis of the pipeline reinforcement sleeve 20 .

[0074] In this embodiment, if Figure 1 As shown, the sleeve push rod can be a manual screw push rod, and the sleeve push rod can be extended and retracted by manually rotating the screw. The sleeve push rod is extended and retracted to push the pipeline reinforcement sleeve 20 to reach a preset position.

[0075] In this embodiment, a sleeve push rod is provided on the second tube clamp fixing frame 310 , and the sleeve push rod is rotated to extend toward the first tube clamp fixing frame 210 , thereby pushing the pipeline reinforcement sleeve 20 to move toward the second tube clamp fixing frame 310 .

[0076] In this embodiment, optionally, while a sleeve push rod is provided on the second tube clamp fixing frame 310, a sleeve push rod is also provided on the first tube clamp fixing frame 210. By rotating the sleeve push rod to extend it toward the first tube clamp fixing frame 210, the pipeline reinforcement sleeve 20 can be pushed to move toward the second tube clamp fixing frame 310; at the same time, by rotating the sleeve push rod to extend it toward the second tube clamp fixing frame 310, the pipeline reinforcement sleeve 20 can be pushed to move toward the first tube clamp fixing frame 210. Therefore, the position can be adjusted by moving in two directions axially on the conveying pipeline through the two sleeve push rods.

[0077] In other embodiments, the sleeve push rod may also be a hydraulic cylinder, and the position of the pipeline reinforcement sleeve 20 is adjusted by extending and retracting the hydraulic cylinder.

[0078] As an optional implementation, a first swing arm 220 locking piece is provided on the first swing arm 220 , and at the same time, a second swing arm locking piece 350 is provided on the second swing arm 320 .

[0079] In this embodiment, if Figure 1 and Figure 2 As shown, a first swing arm 220 locking member is provided on the first swing arm 220. When the first swing arm 220 is closed to be fixed on the conveying pipeline, the first swing arm 220 and the first pipe clamping fixing frame 210 are fixed together by the first swing arm 220 locking member, so that the first pipe clamping positioning unit 200 can be fixed on the conveying pipeline. Similarly, a second swing arm locking member 350 is provided on the second swing arm 320. When the second swing arm 320 is closed to be fixed on the conveying pipeline, the second swing arm 320 and the second pipe clamping fixing frame 310 are fixed together by the second swing arm locking member 350, so that the second pipe clamping positioning unit 300 can be fixed on the conveying pipeline.

[0080] As an optional implementation, the first tube clamping and positioning unit 200 includes two first swing arms 220, and the two first swing arms 220 are respectively arranged at two ends of the first tube clamping and fixing frame 210;

[0081] The second tube clamping positioning unit 300 includes two second swing arms 320 , and the two second swing arms 320 are respectively disposed at two ends of the second tube clamping fixing frame 310 .

[0082] In this embodiment, if Figure 1As shown, the first pipe clamping positioning unit 200 includes two first swing arms 220, and the two first swing arms 220 are respectively arranged at the two ends of the first pipe clamping fixing frame 210. By closing the two swing arms, the first pipe clamping positioning unit 200 can be clamped in the conveying pipe. Since two first swing arms 220 are provided in this embodiment, the swing amplitude and swing range of the first swing arm 220 are smaller than the swing amplitude and swing range of the first pipe clamping positioning unit 200 with only one first swing arm 220, and it can be applied to the construction environment of the conveying pipe is relatively compact or there are many obstacles.

[0111] The pipe reinforcement sleeve 20 set welding device of the present application will be further described below in conjunction with the method of using the pipe reinforcement sleeve 20 set welding device of the present embodiment.

[0112] When the pipe reinforcement sleeve 20 assembly welding device is in the initial state, the first swing arm 220 of the first tube clamping positioning unit 200, the second swing arm 320 of the second tube clamping positioning unit 300, the first gear mounting plate 520 and the second gear mounting plate 540 in the sleeve rotating unit 500 are all in the open state, and the first sleeve adsorption assembly 610 and the second sleeve adsorption assembly 620 of the sleeve adsorption assembly unit 600 are in a relatively horizontal position.

[0113] When the pipe reinforcement sleeve 20 set welding device is in working state, after the entire device of the pipe reinforcement sleeve 20 set welding device is hoisted onto the conveying pipe by an external lifting machine, the first swing arm 220 of the first pipe clamping and positioning unit 200 is closed under the drive of the first swing arm driving cylinder 260, and the two first swing arms 220 are locked by the first swing arm 220 locking member; at the same time, the second swing arm 320 of the second pipe clamping and positioning unit 300 is closed under the drive of the second swing arm driving cylinder 360, and the two second swing arms 320 are locked by the second swing arm locking member 350. Afterwards, the first pipe clamping and positioning member 230 of the first pipe clamping and positioning unit 200 and the second pipe clamping and positioning member 330 of the second pipe clamping and positioning unit 300 are pushed out to clamp the pipe reinforcement sleeve 20 set welding device and the conveying pipe and complete the coaxial positioning. After the above actions are completed, the first gear mounting plate 520 and the second gear mounting plate 540 in the sleeve rotating unit 500 are respectively driven by the first screw assembly and the second screw assembly 570 along the first slide rail 511 and the second slide rail 512 on the beam 510 to move toward each other until the first gear mounting plate 520 and the second gear mounting plate 540 are closed. During the closing process, the positioning pin shafts and positioning pin holes on the first semicircular gear 530 and the second semicircular gear 550 in the sleeve rotating unit 500 are inserted into each other for positioning, and are assembled to form a complete circular gear.

[0114] After the above actions are completed, the first semicircular pipe reinforcement sleeve 20 is hoisted to the welding work position Q2 at the twelve o'clock direction on the top of the conveying pipeline by using an external lifting device. At this time, the first rotary drive motor 523 and the first rotary drive motor 523 in the sleeve rotation unit 500 are started, driving the first rotary drive gear 522 and the second rotary drive gear 542 and synchronously driving the circular gear formed by the first semicircular gear 530 and the second semicircular gear 550 to rotate, and the first sleeve adsorption assembly 6 installed on the first semicircular gear 530 is sucked. 10 rotates to the twelve o'clock direction and stops. At this time, the first adsorption drive cylinder 614 in the first sleeve adsorption assembly 610 extends out, and under the action of the first adsorption guide sleeve 613, the electromagnetic adsorber as the first adsorbent 612 moves toward the first semicircular pipe reinforcement sleeve 20 and stops after contact. The electromagnetic adsorber generates a strong adsorption force to firmly adsorb the first semicircular pipe reinforcement sleeve 20, and then the first adsorption drive cylinder 614 is slightly retracted to make the first semicircular pipe reinforcement sleeve 20 separate from the surface of the conveying pipeline by 3mm to 5mm. Then the first rotation drive motor 523 and the first rotation drive motor 523 in the sleeve rotation unit 500 are started, driving the first rotation drive gear 522 and the second rotation drive gear 542 and synchronously driving the circular gear formed by the first semicircular gear 530 and the second semicircular gear 550 to rotate, so that the first sleeve adsorption assembly 610 adsorbing the first semicircular pipe reinforcement sleeve 20 rotates 180 degrees to the six o'clock direction at the bottom of the conveying pipeline.

[0115] After the above actions are completed, an external lifting device is used to hoist the second semicircular pipe reinforcement sleeve 20 to the hoisting work position Q1 at the twelve o'clock direction on the top of the conveying pipeline, and then the second sleeve push rod 340 set on the second pipe clamping positioning unit 300 is operated to extend the second sleeve push rod 340 to push the second semicircular pipe reinforcement sleeve 20 to the welding work position Q2 and align it with the end face of the first semicircular pipe reinforcement sleeve 20. Then, the second adsorption drive cylinder 624 in the second sleeve adsorption assembly 620 is extended, and under the action of the second adsorption guide sleeve 623, the electromagnetic absorber serving as the second adsorption component 622 is moved toward the second semicircular pipe reinforcement sleeve 20 and stops after contact. The electromagnetic absorber generates a strong adsorption force to firmly adsorb the second semicircular pipe reinforcement sleeve 20, and then the second adsorption drive cylinder 624 is operated to retract slightly, so that the second semicircular pipe reinforcement sleeve 20 is also separated from the surface of the conveying pipeline by 3mm to 5mm. Afterwards, the first sleeve adsorption assembly 610 and the second sleeve adsorption assembly 620 in the sleeve adsorption assembly unit 600 can be operated separately to complete the weld assembly of the two semicircular pipe reinforcement sleeves 20 and ensure that the gap between the assembled pipe reinforcement sleeves 20 and the conveying pipe is uniform.

[0116] After the above actions are completed, the first rotary drive motor 523 and the first rotary drive motor 523 in the sleeve rotation unit 500 are started, driving the first rotary drive gear 522 and the second rotary drive gear 542 and synchronously driving the circular gear formed by the first semicircular gear 530 and the second semicircular gear 550 to rotate, and the weld of the assembled pipe reinforcement sleeve 20 is rotated to the twelve o'clock direction of the top of the conveying pipe and then stopped, and then the Z-axis linear module 750, the Y-axis linear module 740, and the X-axis linear module 730 in the welding unit 700 are controlled, and the welding gun 710 is used to complete the spot welding positioning of the weld. Afterwards, the first rotary drive motor 523 and the first rotary drive motor 523 in the sleeve rotation unit 500 are started to drive the first rotary drive gear 522 and the second rotary drive gear 542 and synchronously drive the circular gear formed by the first semicircular gear 530 and the second semicircular gear 550 to rotate, and the assembled pipe reinforcement sleeve 20 is rotated 180 degrees, so that the other weld is rotated to the twelve o'clock direction at the top of the conveying pipe and then stops, and then the Z-axis linear module 750, the Y-axis linear module 740, and the X-axis linear module 730 in the welding unit 700 are controlled, and the welding gun 710 is used to complete the spot welding positioning of the weld.
