Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, specifically to a pipeline welding positioning auxiliary device. Background Technology

[0002] Steel pipes are typically connected into long pipelines using welding and flanges. Multiple pipe sections need to be placed in suitable positions before being welded together. To prevent misalignment during welding and stress changes after welding, auxiliary supports are required for the welded pipes.

[0003] While existing pipe welding positioning aids can assist in positioning pipes, they cannot rotate the pipes. During pipe welding, workers need to constantly adjust their positions to weld the joints, which greatly affects work efficiency and is inconvenient for workers to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pipe welding positioning auxiliary device to solve the problem mentioned in the background art that although existing pipe welding positioning auxiliary devices can achieve the effect of assisting in pipe positioning, they cannot drive the pipe to rotate. Furthermore, during pipe welding, workers need to adjust their positions from time to time to weld the joints, which greatly affects work efficiency and is inconvenient for workers to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pipe welding positioning auxiliary device, comprising a base, a mounting seat fixedly connected to the top center of the base, a rotating shaft rotatably connected to the inner side of the mounting seat, a transmission gear one fixedly connected to the left end of the rotating shaft, a transmission gear two fixedly connected to the right end of the rotating shaft, connecting seats fixedly connected to both sides of the top of the base, an mounting sleeve fixedly connected to the top of the connecting seat, an mounting groove formed on the inner wall center of the mounting sleeve, a roller rotatably connected inside the mounting groove, a positioning sleeve rotatably connected to the side of the rotating shaft away from the mounting groove, a transmission gear ring fixedly connected to the end surface of the positioning sleeve near the mounting seat, a connecting rod fixedly connected to the end surface of the positioning sleeve away from the mounting seat, an auxiliary ring fixedly connected to the side of the connecting rod away from the positioning sleeve, an electric push rod fixedly connected to the inner wall of the positioning sleeve, and a positioning plate fixedly connected to the extension end of the electric push rod.

[0006] Preferably, the number of rollers is several, and the several rollers are distributed in a circular array on the inner wall of the mounting groove, and the spacing between the several rollers is the same.

[0007] Preferably, there are two mounting sleeves, which are symmetrically distributed on the top of the two connecting seats, and each mounting sleeve is provided with a positioning sleeve inside.

[0008] By adopting the above technical solution, and by setting up installation sleeves, positioning sleeves and other components in conjunction with rollers, the positioning sleeve can rotate inside the installation sleeve via the rollers, thereby causing the pipe inside the positioning sleeve to rotate and changing the position of the pipe joint. This allows for welding at different positions of the joint without requiring workers to adjust their positions, improving work efficiency and making it easier for workers to use.

[0009] Preferably, there are two transmission gear rings, which are located on the surfaces of the two positioning sleeves respectively, and both transmission gear rings are located on the side of the two positioning sleeves that are close to each other.

[0010] Preferably, the upper sides of the first transmission gear and the second transmission gear respectively mesh with the lower sides of the transmission gear rings of the two positioning sleeves.

[0011] The above technical solution involves using a positioning sleeve with a transmission gear 1, a transmission gear 2, and a transmission gear ring. The positioning sleeve drives the transmission gear 1 to rotate via the transmission gear ring. The rotation of the transmission gear 1 then drives the transmission gear 2 to rotate via a rotating shaft. The transmission gear 2, in turn, drives the other positioning sleeve to rotate synchronously via the transmission gear ring. This avoids misalignment at the pipe joint caused by asynchronous rotation of the two positioning sleeves, and facilitates use by personnel.

[0012] Preferably, there are several electric push rods, which are arranged in a circular array on the inner wall of the positioning sleeve, and the spacing between the electric push rods is the same.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This pipe welding positioning auxiliary device uses an installation sleeve, a positioning sleeve, and a roller. The positioning sleeve can rotate inside the installation sleeve via the roller, thereby rotating the pipe inside the positioning sleeve and changing the position of the pipe joint. This allows for welding at different positions of the joint without requiring the operator to adjust their position, improving work efficiency and making it easier for operators to use.

[0015] 2. This pipe welding positioning auxiliary device uses a positioning sleeve in conjunction with a transmission gear 1, a transmission gear 2, and a transmission gear ring. The positioning sleeve drives the transmission gear 1 to rotate via the transmission gear ring. The rotation of the transmission gear 1 drives the rotation of the transmission gear 2 via a rotating shaft. The transmission gear 2 drives the other positioning sleeve to rotate synchronously via the transmission gear ring. This prevents misalignment at the pipe joint caused by asynchronous rotation of the two positioning sleeves and makes it convenient for workers to use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Example 1:

[0024] Referring to Figures 1-4, a pipe welding positioning auxiliary device includes a base 1. A mounting seat 2 is fixedly connected to the top center of the base 1. A rotating shaft 3 is rotatably connected to the inner side of the mounting seat 2. A transmission gear 4 is fixedly connected to the left end of the rotating shaft 3, and a transmission gear 15 is fixedly connected to the right end of the rotating shaft 3. Connecting seats 5 are fixedly connected to both sides of the top of the base 1. A mounting sleeve 6 is fixedly connected to the top of the connecting seat 5. A mounting groove 7 is formed on the inner wall of the mounting sleeve 6. Rollers 8 are rotatably connected inside the mounting groove 7. Several rollers 8 are arranged in a circular array on the inner wall of the mounting groove 7. The spacing between the shafts 8 is the same. The side of the rotating shaft 3 away from the mounting groove 7 is rolled with a positioning sleeve 9. There are two mounting sleeves 6, which are symmetrically distributed on the top of the two connecting seats 5. The positioning sleeves 6 are both equipped with positioning sleeves 9. The end surface of the positioning sleeve 9 near the mounting seat 2 is fixedly connected with a transmission gear ring 10. The end surface of the positioning sleeve 9 away from the mounting seat 2 is fixedly connected with a connecting rod 11. The side of the connecting rod 11 away from the positioning sleeve 9 is fixedly connected with an auxiliary ring 12. The inner wall of the positioning sleeve 9 is fixedly connected with an electric push rod 13. The extension end of the electric push rod 13 is fixedly connected with a positioning plate 14.

[0025] Working principle: During use, the operator inserts the two sections of pipe to be welded into the two positioning sleeves 9, ensuring that one end of each pipe is in contact with the other. Then, the operator activates the electric push rod 13, which pushes the positioning plate 14 to clamp and position the pipes. At this point, the operator can weld the joint between the two pipes. When the operator needs to change the position of the joint, they only need to hold the auxiliary ring 12 to rotate the positioning sleeve 9. The positioning sleeve 9 rotates inside the mounting sleeve 6 via the roller 8, thereby rotating the pipe inside the positioning sleeve 9 and changing the position of the pipe joint. Welding at different positions of the joint can be performed without the operator needing to adjust their position, improving work efficiency and making it easier for operators to use.

[0026] Compared with related technologies, the pipe welding positioning auxiliary device provided by this utility model has the following beneficial effects: by setting up an installation sleeve 6, a positioning sleeve 9 and other components to work with a roller 8, the positioning sleeve 9 can rotate inside the installation sleeve 6 through the roller 8, thereby driving the pipe inside the positioning sleeve 9 to rotate, thereby changing the position of the pipe joint. Welding can be performed at different positions of the joint without the need for the operator to adjust their position, which improves work efficiency and makes it easier for the operator to use.

[0027] Example 2:

[0028] Referring to Figures 1-5, a mounting base 2 is fixedly connected to the top center of the base 1. A rotating shaft 3 is rotatably connected to the inner side of the mounting base 2. A transmission gear 4 is fixedly connected to the left end of the rotating shaft 3, and a transmission gear 15 is fixedly connected to the right end of the rotating shaft 3. Connecting seats 5 are fixedly connected to both sides of the top of the base 1. A mounting sleeve 6 is fixedly connected to the top of the connecting seat 5. A mounting groove 7 is opened on the inner wall center of the mounting sleeve 6. A roller 8 is rotatably connected inside the mounting groove 7. A positioning sleeve 9 is rotatably connected to the side of the rotating shaft 3 away from the mounting groove 7. A transmission gear ring 10 is fixedly connected to the surface of the positioning sleeve 9 near the mounting base 2. There are two transmission gear rings 10. The two transmission gear rings 10 are located on the surfaces of the two positioning sleeves 9, and the two transmission gear rings 10 are located on the side of the two positioning sleeves 9 that are close to each other. The upper sides of the transmission gear 4 and the transmission gear 15 mesh with the lower sides of the transmission gear rings 10 of the two positioning sleeves 9, respectively.

[0029] Working principle: When the operator rotates the positioning sleeve 9 via the auxiliary ring 12, the positioning sleeve 9 will drive the transmission gear 4 to rotate via the transmission gear ring 10. The rotation of the transmission gear 4 will drive the transmission gear 15 to rotate via the rotating shaft 3. The transmission gear 15 will drive the other positioning sleeve 9 to rotate synchronously via the transmission gear ring 10. The two positioning sleeves 9 will then drive the two pipes to rotate synchronously, avoiding misalignment at the pipe joint caused by asynchronous rotation of the two positioning sleeves 9, and making it convenient for operators to use.

[0030] Compared with related technologies, the pipe welding positioning auxiliary device provided by this utility model has the following beneficial effects: by setting up a transmission gear 4, a transmission gear 15, a transmission gear ring 10, etc., in conjunction with the positioning sleeve 9, the positioning sleeve 9 drives the transmission gear 4 to rotate through the transmission gear ring 10. The rotation of the transmission gear 4 will drive the transmission gear 15 to rotate through the rotating shaft 3. The transmission gear 15 drives the other positioning sleeve 9 to rotate synchronously through the transmission gear ring 10, avoiding the situation where the two positioning sleeves 9 rotate asynchronously, thus preventing misalignment at the pipe splice and making it convenient for workers to use.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
