Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary equipment technology, specifically to a steel structure butt welding adjustment device. Background Technology

[0002] In the construction of steel structure connections, butt welding of steel pipes is the most common and crucial step. It is widely used in buildings, bridges, offshore platforms, and various pipeline systems.

[0003] Traditional short steel pipe welding often involves placing the pipe in a specially designed arc-shaped groove and then clamping and fixing it from both ends using jigs. While this method provides a certain degree of stability, it only allows welding on one side of the pipe joint. To complete the welding of the entire circumference, the pipe needs to be flanged to weld the other side. This process increases the complexity of the operation and reduces work efficiency. Furthermore, the flanged operation requires releasing the clamps, and since the pipes are not yet fully fused, movement during this process can lead to misalignment, affecting the final weld quality. Therefore, we propose a steel structure butt welding adjustment device to solve these problems. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0025] This application provides a steel structure butt welding adjustment device, mainly to address the problem that while existing technologies can provide a certain degree of stability, they can only weld one side of the steel pipe joint. To complete the welding of the entire circumference, the steel pipe needs to be flanged to weld the other side. This process increases operational complexity and reduces work efficiency. Furthermore, the flanged operation requires releasing the clamps, and since the steel pipes are not yet fully fused, movement during this operation may cause misalignment, affecting the final weld quality. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0026] A steel structure butt welding adjustment device, comprising:

[0027] Fixed plate 1, with a U-shaped plate 2 fixed on the top of fixed plate 1;

[0028] The first positioning cylinder 3 is fixedly embedded in the middle of the top of the U-shaped plate 2;

[0029] The support plate 4 is set between the bottom of the inner side wall of the U-shaped plate 2. The height of the support plate 4 is adjustable. Rectangular through holes 201 are formed at equal intervals on one bottom side of the U-shaped plate 2, and round holes 202 are formed at equal intervals on the other bottom side of the U-shaped plate 2. The support plate 4 slides through the inside of the rectangular through holes 201. A limiting plate 402 is fixed on one line of the support plate 4, and a connecting rod 403 is connected to the other side of the support plate 4. The connecting rod 403 passes through the inside of the round hole 202.

[0030] The second positioning cylinder 5 is rotatably connected to the top center of the bearing plate 4 via a rotating shaft;

[0031] Clamping member 6 is disposed on the upper side inside the first positioning cylinder 3. Clamping member 6 is used to clamp and fix the steel pipe to be welded.

[0032] The locking element 7 is located on the bottom side of the second positioning cylinder 5 and is used to prevent the second positioning cylinder 5 from rotating.

[0033] It should be noted that the outer diameter of the two steel pipes to be welded in this device is the same as the inner diameter of the first positioning cylinder 3 and the second positioning cylinder 5.

[0034] Workflow Description:

[0035] The first step is to adjust the height of the bearing plate 4. Based on the length of the two steel pipes to be welded, insert the bearing plate 4 into the rectangular through hole 201 at a suitable height, and make the connecting rod 403 pass through the circular hole 202 at the corresponding height. At the same time, the limiting plate 402 abuts against the outer wall of the U-shaped plate 2. At this time, the first positioning cylinder 3 and the second positioning cylinder 5 are exactly concentric. It is necessary to ensure that after the height of the bearing plate 4 is adjusted, the welding position of the steel pipe is exposed in the gap between the first positioning cylinder 3 and the second positioning cylinder 5.

[0036] The second step is to place the steel pipes: Clean the two steel pipes to be welded, place the longer steel pipe in the second positioning cylinder 5, and place the shorter steel pipe in the second positioning cylinder 5 (if they are the same, just place them randomly).

[0037] The third step is to fix the steel pipe to be welded using clamping component 6;

[0038] The fourth step is to start the welding equipment and weld one side of the steel pipe;

[0039] Fifth step: After completing the welding of one side of the steel pipe, the locking part 7 can be released from the second positioning cylinder 5. After rotating the second positioning cylinder 5 180 degrees (or 90 degrees), the second positioning cylinder 5 is locked again by the locking part 7. The welding equipment is restarted to weld the other side of the steel pipe. Since the two steel pipes are always inside the first positioning cylinder 3 and the second positioning cylinder 5, they are not easy to be misaligned.

[0040] The device achieves precise positioning of the steel pipe through the combined use of the first positioning cylinder 3 and the second positioning cylinder 5, effectively avoiding misalignment during the welding process. Through the cooperation of the clamping part 6 and the locking part 7, the steel pipe can be clamped quickly and the stability during the welding process can be guaranteed, significantly improving the quality and effect of the weld.

[0041] like Figure 2 As shown, in some embodiments, the connecting rod 403 is a threaded rod, and its end is threadedly connected to a locking sleeve 404. More specifically, when the locking sleeve 404 is screwed into the connecting rod 403, and one side of the locking sleeve 404 abuts against the outer wall of the U-shaped plate 2, the bearing plate 4 can be fixed in an accurate position (the first positioning cylinder 3 and the second positioning cylinder 5 are concentric).

[0042] like Figure 1 As shown, in some embodiments, the bottom side of the first positioning cylinder 3 is provided with a first notch 301, and the same side of the upper side of the second positioning cylinder 5 is provided with a second notch 501. More specifically, the design of the first notch 301 and the second notch 501 allows the operator to easily insert the steel pipe into the two positioning cylinders. This simplicity reduces the difficulty of operation and improves work efficiency.

[0043] like Figure 4As shown, in some embodiments, the clamping member 6 includes a mounting rod 601 threadedly connected to the top of the first positioning cylinder 3. The bottom end of the mounting rod 601 is rotatably connected to an abutment plate 602 via a bearing. The abutment plate 602 is slidably connected to the inner wall of the first positioning cylinder 3. More specifically, when the mounting rod 601 is rotated, it pushes the abutment plate 602 downward together. When the abutment plate 602 contacts the surface of the steel pipe, it applies a radial force to tightly clamp the steel pipe inside the first positioning cylinder 3. By adjusting the height of the mounting rod 601, it can adapt to the welding requirements of steel pipes of different lengths.

[0044] like Figure 2 As shown, in some embodiments, the locking element 7 includes an extension plate 701 fixed to the bottom side of the second positioning cylinder 5. A pin 702 is slidably inserted into the side of the extension plate 701 away from the second positioning cylinder 5. The surface of the support plate 4 has pin holes 401 arranged in a ring array on the side of the second positioning cylinder 5. The pin 702 is adapted to the size of the pin holes 401. More specifically, when it is necessary to lock the second positioning cylinder 5, the operator slides the pin 702 along the extension plate 701 to the position of the pin hole 401, and then gently inserts it into the pin hole 401. Since the pin 702 and the pin hole 401 adopt an interference fit or clearance fit (depending on the specific design), once the pin 702 is inserted into the pin hole 401, a tight connection can be formed, thereby firmly fixing the second positioning cylinder 5 to the support plate 4. After welding is completed, the operator can pull the pin 702 out of the pin hole 401 by a simple operation (such as pulling the unlocking lever on the pin 702 or rotating the pin 702) to achieve quick unlocking.

[0045] like Figure 1 As shown, in some embodiments, mounting holes 101 are provided at the four corners of the fixing plate 1. More specifically, the main function of the mounting holes 101 is to connect the fixing plate 1 to the work platform or bracket by bolts or other fasteners to form a stable support structure. The fixing plate 1 can be stably connected to the work platform to provide reliable support and positioning for the entire device, thereby ensuring the accurate docking and welding quality of the steel pipe.
