Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, specifically to a rapid pipe welding jointing device. Background Technology

[0002] In many engineering construction, installation, and maintenance processes, butt welding of two pipes with the same diameter is often involved. To ensure that the coaxiality (i.e., the degree of alignment) of the pipes (especially long-distance transport pipes) meets the specifications during butt welding, and to avoid defects such as misalignment or pipe kinks that could cause additional stress and affect the life of the pipes, a pipe welding butt welding tool is usually used to align the ends of the two pipes.

[0003] In existing technologies, conventional pipe alignment is done manually, which consumes a lot of manpower and time, resulting in low work efficiency. Furthermore, uneven pipe joints affect welding quality, and it is impossible to accurately control the spacing between pipe joints, making it very inconvenient to use. Utility Model Content

[0004] This invention provides a rapid pipe welding joint device to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid pipe welding mating device, comprising a first rectangular box, a first driving mechanism fixedly installed between the left and right side walls of the first rectangular box, a first mounting plate fixedly installed on the lower surface of the slider of the first driving mechanism and near the right side of the lower surface of the first rectangular box, a second rectangular box fixedly installed on the lower surface of the first mounting plate, a second driving mechanism provided between the front and rear inner walls of the second rectangular box, a second mounting plate fixedly installed on the lower surface of the second driving mechanism near the front and rear positions, a locking mechanism fixedly installed on the lower surface of the second mounting plate, and an arc-shaped clamping plate installed on the lower surface of the locking mechanism.

[0006] Furthermore, the lower surfaces of both the first rectangular box and the second rectangular box are open structures.

[0007] Furthermore, the first drive mechanism includes a first ball screw, a first bearing assembly, a first handle, and a first ball nut. The first ball screw is mounted between the left and right side walls of the first rectangular box via the first bearing assembly. A first handle is fixedly mounted on the right end of the first ball screw. A first ball nut is provided on the first ball screw, and the lower surface of the first ball nut is fixedly connected to the upper surface of the left first mounting plate.

[0008] Furthermore, the outer surface of the first ball nut is rectangular, and the outer surface of the first ball nut is in movable contact with the inner wall of the first rectangular box.

[0009] Furthermore, the second drive mechanism includes a second ball screw, a second bearing assembly, a second handle, and a second ball nut. There are two second ball screws arranged in a front-to-back mirror configuration, and the facing ends of the second ball screws are fixedly connected. The second ball screws are mounted between the front and rear inner walls of the second rectangular box through the second bearing assembly. A second handle is fixedly mounted on each of the far ends of the second ball screws. A second ball nut is provided on each of the second ball screws, and the lower surface of the second ball nut is fixedly connected to the upper surface of the second mounting plate.

[0010] Furthermore, the outer surface of the second ball nut is rectangular, and the outer surface of the second ball nut is in movable contact with the inner wall of the second rectangular box.

[0011] Furthermore, the locking mechanism includes a rectangular sleeve, a threaded hole, a through hole, and a locking bolt. The rectangular sleeve is fixedly installed on the lower surface of the second mounting plate. Threaded holes are provided on the front and rear side walls of the rectangular sleeve. Through holes are provided on the arc-shaped clamping plate corresponding to the threaded holes. Locking bolts are installed in the threaded holes, and the locking bolts lock the rectangular sleeve and the arc-shaped clamping plate in place.

[0012] Compared with the prior art, this utility model provides a rapid pipe welding jointing device, which has the following beneficial effects:

[0013] This rapid pipe welding alignment device, through a second drive mechanism within a left and right second rectangular box, drives the front and rear arc-shaped clamping plates to move towards each other via a locking mechanism. This allows for quick fixation of two pipes. Simultaneously, a first drive mechanism within a first rectangular box, via a first mounting plate, moves the left second rectangular box to the right. This, in turn, causes the second rectangular box to move the left pipe between the left arc-shaped clamping plates to the right via the second drive mechanism, adjusting the distance between the left and right pipe joints. This results in more accurate welding positions and higher quality. Furthermore, the locking mechanism allows the arc-shaped clamping plates to be installed and removed. Different arc-shaped clamping plates can accommodate pipes of different diameters, thus meeting the needs of welding joints for various pipe specifications, making it highly practical.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-3 This utility model discloses a rapid pipe welding mating device, including a first rectangular box 1. A first driving mechanism 2 is fixedly installed between the left and right side walls of the first rectangular box 1. A first mounting plate 3 is fixedly installed on the lower surface of the slider of the first driving mechanism 2 and near the right side of the lower surface of the first rectangular box 1. A second rectangular box 4 is fixedly installed on the lower surface of the first mounting plate 3. A second driving mechanism 5 is provided between the front and rear inner walls of the second rectangular box 4. A second mounting plate 6 is fixedly installed on the lower surface of the second driving mechanism 5 near the front and rear positions. A locking mechanism 7 is fixedly installed on the lower surface of the second mounting plate 6. An arc-shaped clamping plate 8 is installed on the lower surface of the locking mechanism 7.

[0020] Specifically, the lower surfaces of both the first rectangular box 1 and the second rectangular box 4 are open structures.

[0021] In this embodiment, the first drive mechanism 2 inside the first rectangular box 1 can drive the first mounting plate 3 to move left and right, so that the second drive mechanism 5 inside the second rectangular box 4 can drive the second mounting plate 6 to move back and forth.

[0022] Specifically, the first drive mechanism 2 includes a first ball screw 201, a first bearing assembly 202, a first handle 203, and a first ball nut 204. The first ball screw 201 is installed between the left and right side walls of the first rectangular box 1 through the first bearing assembly 202. The first handle 203 is fixedly installed on the right end of the first ball screw 201. The first ball nut 204 is provided on the first ball screw 201. The lower surface of the first ball nut 204 is fixedly connected to the upper surface of the left first mounting plate 3.

[0023] In this embodiment, the first handle 203 drives the first ball screw 201 to rotate in the first bearing assembly 202. The rotation of the first ball screw 201 causes the first ball nut 204 to move left and right, which in turn causes the first ball nut 204 to move the first mounting plate 3 left and right, thereby achieving the effect of adjusting the left and right positions of the left arc-shaped clamp 8.

[0024] Specifically, the outer surface of the first ball nut 204 is rectangular, and the outer surface of the first ball nut 204 is in contact with the inner wall of the first rectangular box 1.

[0025] In this embodiment, the first ball nut 204 can move stably left and right along the first rectangular box 1.

[0026] Specifically, the second drive mechanism 5 includes a second ball screw 501, a second bearing assembly 502, a second handle 503, and a second ball nut 504. There are two second ball screws 501 arranged in a front-to-back mirror configuration, and the facing ends of the second ball screws 501 are fixedly connected. The second ball screws 501 are installed between the front and rear inner walls of the second rectangular box 4 through the second bearing assembly 502. The second handles 503 are fixedly installed on the mutually distant ends of the second ball screws 501. The second ball nut 504 is provided on each of the second ball screws 501, and the lower surface of the second ball nut 504 is fixedly connected to the upper surface of the second mounting plate 6.

[0027] In this embodiment, the second handle 503 drives the second ball screw 501, which is set in a mirror image, to rotate in the front and rear second bearing assemblies 502. The front and rear second ball screws 501 cause the front and rear second ball nuts 504 to move in opposite directions. The front and rear second ball nuts 504 drive the locking mechanism 7 to move back and forth through the second mounting plate 6. The front and rear locking mechanism 7 drives the front and rear arc-shaped clamps 8 to move in opposite directions, so that the front and rear arc-shaped clamps 8 clamp and fix the pipe.

[0028] Specifically, the outer surface of the second ball nut 504 is a rectangular structure, and the outer surface of the second ball nut 504 is in movably fitted with the inner wall of the second rectangular box 4.

[0029] In this embodiment, the second ball nut 504 can move back and forth along the second rectangular box 4, so that the back and forth movement of the second ball nut 504 is stable.

[0030] Specifically, the locking mechanism 7 includes a rectangular sleeve 701, a threaded hole 702, a through hole 703, and a locking bolt 704. The rectangular sleeve 701 is fixedly installed on the lower surface of the second mounting plate 6. The front and rear side walls of the rectangular sleeve 701 are provided with threaded holes 702. The arc-shaped clamping plate 8 corresponding to the threaded holes 702 is provided with through holes 703. The locking bolt 704 is installed in the threaded hole 702, and the locking bolt 704 locks and fixes the rectangular sleeve 701 and the arc-shaped clamping plate 8.

[0031] In this embodiment, the arc-shaped clamping plate 8 is inserted into the rectangular sleeve 701, and then the locking bolt 704 is installed in the threaded hole 702 and the through hole 703 in sequence, so that the locking bolt 704 locks and fixes the rectangular sleeve 701 and the arc-shaped clamping plate 8, so that the arc-shaped clamping plate 8 has the function of disassembly and assembly, and can select the corresponding arc-shaped clamping plate 8 according to the diameter of the pipe, so that the front and rear arc-shaped clamping plates 8 can stably clamp and fix the pipe.

[0032] In use, according to the diameter of the pipe, the corresponding arc-shaped clamping plate 8 is inserted into the rectangular sleeve 701 in the locking mechanism 7. Then, the locking bolts 704 are installed sequentially into the threaded hole 702 and the through hole 703, so that the locking bolts 704 lock and fix the rectangular sleeve 701 and the arc-shaped clamping plate 8. The pipes on the left and right sides are placed between the front and rear arc-shaped clamping plates 8 on the left and right sides respectively. The second handle 503 in the second drive mechanism 5 drives the mirror-shaped second ball screws 501 to rotate in the front and rear second bearing assemblies 502. The front and rear second ball screws 501 cause the front and rear second ball nuts 504 to move back and forth in opposite directions. The front and rear second ball nuts 504 drive the locking mechanism 7 to move back and forth through the second mounting plate 6. The front and rear locking mechanism 7 drives... The front and rear arc-shaped clamping plates 8 move towards each other, clamping and fixing the pipe. Then, the first handle 203 in the first drive mechanism 2 drives the first ball screw 201 to rotate in the first bearing assembly 202. The rotation of the first ball screw 201 causes the first ball nut 204 to move to the right, which in turn drives the first mounting plate 3 to move to the right. The first mounting plate 3, through the second rectangular box 4, drives the locking mechanism 7 on the lower surface of the second drive mechanism 5 to move to the right, causing the locking mechanism 7 to move the left pipe toward the right pipe. This allows for quick fixing of two pipes, adjustment of the distance between the left and right pipe joints, more accurate welding position, higher welding quality, and can meet the welding joint requirements of various pipe specifications, making it highly practical.

[0033] In summary, this rapid pipe welding mating device can quickly fix two pipes together and move the left-side pipe to adjust the distance between them, making the welding position more accurate and of higher quality. It can meet the welding mating needs of various pipe specifications and is highly practical.
