Description

Technical Field

[0001] This utility model relates to the field of pipeline welding, and in particular to a thermal pipeline welding device with a slag removal function. Background Technology

[0002] A heating network, also known as a heating pipeline, consists of heating pipes that originate from boiler rooms, direct-fired turbine rooms, heating centers, etc., and run from heat sources to the heating inlets of buildings. Multiple heating pipes form a network, and these pipes need to be connected by welding, which requires welding equipment.

[0003] Common heating pipe welding equipment only includes welding functions, which can weld heating pipes, but lacks the function of slag removal. It cannot guarantee that the slag can be cleaned after the heating pipe is welded, which easily leads to residual slag at the weld after the heating pipe is welded, and the weld is uneven, which affects the quality of the finished product.

[0004] Therefore, to address the lack of slag removal functionality in the aforementioned thermal pipeline welding devices, a thermal pipeline welding device can be designed to remove and grind slag around the weld seam. Utility Model Content

[0005] To overcome the problem that common heating pipe welding devices lack slag removal capabilities, which cannot guarantee that the slag can be cleaned after welding, leaving residual slag at the weld after the heating pipe is welded, and causing unevenness at the weld joint, the quality of the finished product is affected.

[0006] The technical solution of this utility model is as follows: a thermal pipeline welding device with slag cleaning function, including a base plate; it also includes a support seat, a drive ring, a circular track, a drive plate, a fixing plate, a welding gun, a fixing strip, a slag scraping plate, a connecting strip, and a grinding block. The support seat is set in the middle of the top of the base plate, the drive ring is set in the top of the support seat, the circular track is set in the middle of the inner side of the drive ring, two drive plates are symmetrically arranged on both sides above the circular track, the fixing plate is set in the middle and lower of the two drive plates, the two sides of the fixing plate are welded to the two drive plates respectively, the fixing strip is set in the bottom side of the fixing plate, the slag scraping plate is set in the side of the fixing strip, the fixing strip is fixed to the slag scraping plate by bolts, the connecting strip is set in the lower side of the slag scraping plate, the bottom end of the connecting strip is set with a grinding block, and the welding gun is set in the other side of the bottom of the fixing plate.

[0007] Preferably, by setting up a slag-removing plate and a grinding block around the weld seam of the heat pipe to clean the welding slag and grind the weld seam, it is ensured that the welding slag can be cleaned and the weld seam can be ground after the heat pipe is welded. This solves the problem that common heat pipe welding devices only have the function of welding and can weld heat pipes, but lack the function of welding slag cleaning. They cannot guarantee that the welding slag can be cleaned after the heat pipe is welded, which easily leads to welding slag residue at the weld seam after the heat pipe is welded, and the weld seam of the heat pipe is uneven, which affects the quality of the finished product.

[0008] Preferably, two limit frames are symmetrically arranged on the top two sides of the base plate corresponding to the position of the drive ring. Two support plates are symmetrically arranged on the lower two sides inside the limit frames. The top of the support plates is provided with a placement groove. After the limit plates are lifted upward, the two heat pipes are placed in the placement grooves in the two limit frames respectively, and the two ends of the two heat pipes are aligned with the positions of the welding guns.

[0009] Preferably, two limit plates are symmetrically arranged on the upper sides of the limit frame, corresponding to the positions of the support plate. A limit groove is opened at the bottom of the limit plate corresponding to the position of the placement groove. During the downward movement of the limit plate, the upper part of the heat pipe is inserted into the interior of the limit groove, and the heat pipe is clamped by the limit plate and the support plate.

[0010] Preferably, the limiting plate has a handle on its side and four springs are evenly spaced on its top. The top of the springs is welded to the top of the limiting frame. After the heat pipe is placed, the handle is released, and the limiting plate is pushed downward by the spring force.

[0011] Preferably, a connecting plate is provided between the two limiting plates, and the two sides of the connecting plate are welded to the two limiting plates respectively. The limiting plates are lifted upward by the handle. When one limiting plate moves upward, the other limiting plate is driven to move upward through the connecting plate.

[0012] Preferably, two rollers are symmetrically arranged on the sides of each drive plate corresponding to the position of the circular track. The rollers are inserted into the interior of the circular track, and the rotating rollers move around the circular track. At the same time, the rollers drive the welding gun, slag removal plate and grinding block to rotate around the joint of the two ends of the two heat pipes through the fixed plate. During the rotation, the welding gun welds the two heat pipes, the slag removal plate removes the welding slag at the weld, and the grinding block grinds the uneven areas at the weld.

[0013] Preferably, two motors are installed on the other side of each of the two drive plates, corresponding to the position of the rollers. The output end of the motor passes through the drive plate and is connected to the roller. After the thermal pipe is limited, the motor and welding gun are started, and the motor drives the roller to rotate.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up slag scraping plates and grinding blocks around the weld seam of the heating pipe, the welding slag is cleaned and the weld seam is ground. This ensures that the welding slag can be cleaned and the weld seam can be ground after the heating pipe is welded. This solves the problem that common heating pipe welding devices only have the function of welding and can weld heating pipes, but lack the function of welding slag cleaning. They cannot guarantee that the welding slag can be cleaned after the heating pipe is welded. This can easily result in welding slag residue at the weld seam after the heating pipe is welded, and the weld seam of the heating pipe is uneven, which affects the quality of the finished product.

[0016] 2. After the thermal pipe is positioned, start the motor and welding torch. The motor drives the roller to rotate, and the rotating roller moves around a circular track. At the same time, the roller drives the welding torch, slag scraper, and grinding block to rotate around the joint of the two thermal pipes through the fixed plate. During the rotation, the welding torch welds the two thermal pipes, the slag scraper removes the welding slag at the weld, and the grinding block grinds the uneven areas at the weld, thus achieving the function of cleaning welding slag.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4 This utility model provides an embodiment of a thermal pipeline welding device with slag removal function, including a base plate 1; it also includes a support base 10, a drive ring 11, a circular track 12, a drive plate 13, a fixing plate 14, a welding torch 17, a fixing strip 18, a slag removal plate 19, a connecting strip 20, and a grinding block 21. The support base 10 is arranged in the middle of the top of the base plate 1, and the drive ring 11 is arranged on the top of the support base 10. The circular track 12 is arranged in the middle of the inner side of the drive ring 11. Two drive plates 13 are symmetrically arranged on both sides above the circular track 12. The fixing plate 14 is arranged below the middle of the two drive plates 13. The two sides of the fixing plate 14 are welded to the two drive plates 13 respectively. The fixing strip 18 is arranged on the bottom side of the fixing plate 14, and the slag removal plate 19 is arranged on the side of the fixing strip 18. 9. The fixing strip 18 is fixed to the slag removal plate 19 by bolts. A connecting strip 20 is provided on the lower side of the slag removal plate 19, and a grinding block 21 is provided at the bottom end of the connecting strip 20. A welding gun 17 is provided on the other side of the bottom of the fixing plate 14. By setting the slag removal plate 19 and the grinding block 21 around the weld of the heat pipe, the welding slag is cleaned and the weld is ground. This ensures that the welding slag can be cleaned and the weld can be ground after the heat pipe is welded. This solves the problem that common heat pipe welding devices only have the function of welding and can weld heat pipes, but lack the function of welding slag cleaning. They cannot guarantee that the welding slag can be cleaned after the heat pipe is welded. This can easily result in welding slag residue at the weld after the heat pipe is welded, and the weld of the heat pipe is uneven, which affects the quality of the finished product.

[0024] Please see Figures 2-4In this embodiment, two limit frames 2 are symmetrically arranged on the top two sides of the base plate 1, corresponding to the positions of the drive ring 11. Two support plates 3 are symmetrically arranged on the lower two sides inside the limit frames 2. The top of the support plates 3 has a placement groove 4. Two limit plates 5 are symmetrically arranged on the upper two sides inside the limit frames 2, corresponding to the positions of the support plates 3. The bottom of the limit plates 5 has a limit groove 6 corresponding to the position of the placement groove 4. A handle 7 is provided on the side of the limit plates 5. Four springs 8 are equally spaced on the top of the limit plates 5. The top of the springs 8 is welded to the top of the inside of the limit frame 2. A connecting plate 9 is provided between the two limit plates 5. The two sides of the connecting plate 9 are respectively connected to the top of the limit frame 2. Two limiting plates 5 are welded together. The limiting plates 5 are lifted upward by the handle 7. When one limiting plate 5 moves upward, the other limiting plate 5 is moved upward by the connecting plate 9. After the limiting plates 5 are lifted upward, the two hot pipes are placed in the placement slots 4 in the two limiting frames 2 respectively, and the two ends of the two hot pipes are aligned with the positions of the welding gun 17. After the hot pipes are placed, the handle 7 is released. At this time, the limiting plate 5 is pushed downward by the pushing force of the spring 8. During the downward movement of the limiting plate 5, the upper part of the hot pipe is inserted into the interior of the limiting slot 6. The limiting plate 5, together with the support plate 3, clamps the hot pipe, thus completing the limiting work of the hot pipe.

[0025] Please see Figures 1-4 In this embodiment, two rollers 15 are symmetrically arranged on the sides of each of the two drive plates 13, corresponding to the positions of the circular track 12. The rollers 15 are inserted into the interior of the circular track 12. Two motors 16 are arranged on the other sides of each of the two drive plates 13, corresponding to the positions of the rollers 15. The output ends of the motors 16 pass through the drive plates 13 and are connected to the rollers 15. After the heat pipe is limited, the motors 16 and the welding torch 17 are started. The motors 16 drive the rollers 15 to rotate, and the rotating rollers 15 move around the circular track 12. At the same time, the roller 15 drives the welding gun 17, the slag removal plate 19 and the grinding block 21 to rotate around the two ends of the two heat pipes through the fixed plate 14. During the rotation, the welding gun 17 welds the two heat pipes, the slag removal plate 19 removes the welding slag at the weld, and the grinding block 21 grinds the uneven parts of the weld. This achieves the function of cleaning welding slag and prevents the welding slag from remaining at the weld after the heat pipes are welded, and also prevents the unevenness of the weld joint from affecting the quality of the finished product.

[0026] During operation, the limiting plate 5 is lifted upwards using handle 7. As one limiting plate 5 moves upwards, the other limiting plate 5 is simultaneously moved upwards via connecting plate 9. After the limiting plate 5 is lifted, the two heating pipes are placed into the placement slots 4 within the two limiting frames 2, with the ends of the two heating pipes aligned with the positions of the welding torch 17. After the heating pipes are placed, handle 7 is released. At this point, the limiting plate 5 is pushed downwards by the force of spring 8. During this downward movement, the upper part of the heating pipe is engaged inside the limiting slot 6. The limiting plate 5, in conjunction with the support plate... 3. Clamp the heating pipes. After the heating pipes are positioned, start the motor 16 and welding torch 17. The motor 16 drives the roller 15 to rotate. The rotating roller 15 moves around the circular track 12. At the same time, the roller 15 drives the welding torch 17, the slag removal plate 19 and the grinding block 21 to rotate around the two ends of the heating pipes through the fixing plate 14. During the rotation, the welding torch 17 welds the two heating pipes, the slag removal plate 19 removes the welding slag at the weld, and the grinding block 21 grinds the uneven areas at the weld, thus achieving the function of cleaning welding slag.

[0027] Through the above steps, by setting up the slag removal plate 19 and the grinding block 21 around the weld seam of the heat pipe, the welding slag is cleaned and the weld seam is ground, ensuring that the welding slag can be cleaned and the weld seam can be ground after the heat pipe is welded. This solves the problem that common heat pipe welding devices only have the function of welding and can weld heat pipes, but lack the function of welding slag cleaning. They cannot guarantee that the welding slag can be cleaned after the heat pipe is welded, which easily leads to welding slag residue at the weld seam after the heat pipe is welded, and the weld seam of the heat pipe is uneven, which affects the quality of the finished product.
