Description

Technical Field

[0001] This utility model relates to the field of steel pipe welding technology, and more specifically to a steel pipe welding device that is easy to move. Background Technology

[0002] As an important structural material and fluid transport carrier, steel pipes are widely used in many fields such as building frames, oil and gas transportation, water conservancy projects, and machinery manufacturing. The connection between steel pipes relies heavily on the welding process, and its quality directly affects the safety and service life of the overall structure. Therefore, accurate positioning, reliable fixing and efficient operation of steel pipes during the welding process are crucial.

[0003] Traditional steel pipe welding often relies on fixed welding fixtures or simple support devices. Fixed fixtures are usually large cast iron or welded steel structures that use positioning elements such as V-grooves or chucks to clamp the steel pipes. They have the advantages of good rigidity and high stability, but their inherent defects of being large, heavy, and immobile are becoming increasingly prominent in modern and flexible production scenarios.

[0004] During welding, the steel pipe needs to be welded around its entire length. However, modern steel pipes cannot move freely, making it difficult to weld the bottom section after welding the top. Furthermore, fixing the steel pipe is now quite complex, reducing work efficiency. Welding steel pipes also easily produces harmful welding fumes, which can cause certain damage to the human body. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a steel pipe welding device that is easy to move, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a mobile steel pipe welding device, including a working base, with rotating mechanisms fixedly connected to both sides of the top of the working base, and fixed mechanisms fixedly connected to both sides of each rotating mechanism. A steel pipe to be welded is movably connected inside the fixed mechanism, and an exhaust mechanism is provided on the side of the welding joint of the two steel pipes to be welded. The rotating mechanism includes a servo motor that provides power, a rotating shaft fixedly connected to the side of the servo motor, an output gear fixedly connected to the side of the rotating shaft, a gear ring meshing with the side of the output gear, and a clearance hole opened inside the gear ring. The steel pipe to be welded is located within the clearance hole of the gear ring and does not contact the gear ring. Connecting rods are fixedly connected to both sides of the gear ring, and the gear ring is fixedly connected to the fixed mechanism through the connecting rods.

[0007] Furthermore, a connecting ring is fixedly connected to the side of the gear ring, and a limiting ring is movably sleeved on the connecting ring. The bottom end of the limiting ring is fixedly connected to the top end of the working base.

[0008] Furthermore, a fixing block is fixedly connected to the bottom end of the servo motor, and the bottom end of the fixing block is fixedly connected to the top end of the working base. A support plate is movably connected to the side of the rotating shaft away from the fixing block, and the bottom end of the support plate is fixedly connected to the top end of the working base.

[0009] Furthermore, the fixing mechanism includes a lower limiting plate fixedly connected to the connecting rod, a limiting rod fixedly connected to one side of the top of the lower limiting plate, a threaded rod threadedly connected to the other side of the top of the lower limiting plate, a handwheel fixedly connected to the top of the threaded rod, and an upper limiting plate threadedly connected to the side of the handwheel.

[0010] Furthermore, a limiting hole adapted to the limiting rod is provided on the side of the upper limit plate away from the threaded rod. The limiting rod is located in the limiting hole of the upper limit plate, and the fixing mechanism does not contact the working base when the whole rotating.

[0011] Furthermore, the exhaust mechanism includes a supporting and fixed lifting block, a fixed housing is fixedly connected to the top of the lifting block, an output motor is fixedly connected inside the fixed housing, and a blade assembly is fixedly connected to the side of the output motor.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model comprises a lower limit plate, an upper limit plate, a gear ring, and an output gear. The steel pipe to be welded is placed inside the lower limit plate. Rotating the handwheel drives the threaded rod to rotate, causing the upper limit plate to move downwards, thereby fixing the position of the steel pipe to be welded. After the steel pipe is fixed, the servo motor starts and drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the output gear to rotate, which in turn drives the gear ring to rotate. When the gear ring rotates, the entire fixing mechanism rotates, thereby causing the steel pipe to be welded to rotate automatically. This allows the steel pipe to be welded to rotate automatically during welding, facilitating the welding process.

[0014] 2. This utility model is equipped with an output motor and a blade assembly. When two steel pipes to be welded are being welded, the output motor starts and drives the blade assembly to rotate. When the blade assembly rotates, it performs air extraction, thereby removing the fumes generated during the welding of the steel pipes and ensuring the safety of the workers.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 This utility model provides a mobile steel pipe welding device, including a working base 1. Rotating mechanisms 2 are fixedly connected to both sides of the top of the working base 1. Fixing mechanisms 3 are fixedly connected to both sides of each rotating mechanism 2. The steel pipe 4 to be welded is movably connected inside the fixing mechanism 3. An exhaust mechanism 5 is provided on the side of the welding joint of the two steel pipes 4 to be welded.

[0023] In this embodiment, rotating mechanisms 2 are fixedly connected to both sides of the top of the working base 1, and each rotating mechanism 2 is provided with a fixing mechanism 3 on both sides. The two fixing mechanisms 3 on each side can fix and support the steel pipe 4 to be welded, so that the positions of the two steel pipes 4 to be welded can be determined. After the positions of the steel pipes 4 to be welded are determined, the quality of welding is improved.

[0024] Reference Figure 2 and Figure 3The rotating mechanism 2 includes a servo motor 202 that provides power. A rotating shaft 203 is fixedly connected to the side of the servo motor 202. An output gear 204 is fixedly connected to the side of the rotating shaft 203. A gear ring 206 meshes with the side of the output gear 204. A clearance hole is provided inside the gear ring 206. The steel pipe 4 to be welded is located in the clearance hole of the gear ring 206, and the steel pipe 4 to be welded does not contact the gear ring 206. Connecting rods 209 are fixedly connected to both sides of the gear ring 206. The gear ring 206 is connected to the connecting rods 209. 09 is fixedly connected to the fixing mechanism 3. A connecting ring 207 is fixedly connected to the side of the gear ring 206. A limiting ring 208 is movably sleeved on the connecting ring 207. The bottom end of the limiting ring 208 is fixedly connected to the top end of the working base 1. A fixing block 201 is fixedly connected to the bottom end of the servo motor 202. The bottom end of the fixing block 201 is fixedly connected to the top end of the working base 1. A support plate 205 is movably connected to the side of the rotating shaft 203 away from the fixing block 201. The bottom end of the support plate 205 is fixedly connected to the top end of the working base 1.

[0025] In this embodiment, the servo motor 202 starts and drives the rotating shaft 203 to rotate. When the rotating shaft 203 rotates, it drives the output gear 204 to rotate. When the output gear 204 rotates, it drives the gear ring 206 on the side to rotate. When the gear ring 206 rotates, it drives the fixing mechanism 3 to rotate as a whole through the connecting rod 209. When the fixing mechanism 3 rotates as a whole, it drives the steel pipe 4 to be welded inside it to rotate. The steel pipe 4 to be welded does not contact the gear ring 206 and will not affect the rotating steel pipe 4. When the gear ring 206 rotates, the connecting ring 207 rotates inside the limiting ring 208 to ensure the stability of the rotation of the gear ring 206.

[0026] Reference Figure 2 and Figure 4 The fixing mechanism 3 includes a lower limit plate 301 fixedly connected to the connecting rod 209. A limit rod 302 is fixedly connected to one side of the top of the lower limit plate 301, and a threaded rod 304 is threadedly connected to the other side of the top of the lower limit plate 301. A handwheel 305 is fixedly connected to the top of the threaded rod 304, and an upper limit plate 303 is threadedly connected to the side of the handwheel 305. A limit hole adapted to the limit rod 302 is opened on the side of the upper limit plate 303 away from the threaded rod 304. The limit rod 302 is located in the limit hole of the upper limit plate 303. The fixing mechanism 3 does not contact the working base 1 when it rotates as a whole.

[0027] In this embodiment, when the handwheel 305 rotates, it drives the threaded rod 304 to rotate. After the threaded rod 304 rotates, the handwheel 305 drives the upper limit plate 303 to move downward. After the handwheel 305 moves downward, it clamps and fixes the steel pipe 4 to be welded placed in the lower limit plate 301 with the lower limit plate 301. Therefore, the clamping and fixing work can be performed automatically. Moreover, the rotating mechanism 2 can drive the fixing mechanism 3 to rotate as a whole, so one round of welding work can be performed.

[0028] Reference Figure 5 The exhaust mechanism 5 includes a support and fixing lifting block 501. The top of the lifting block 501 is fixedly connected to a fixing shell 502. The inside of the fixing shell 502 is fixedly connected to an output motor 503. The side of the output motor 503 is fixedly connected to a blade assembly 504.

[0029] In this embodiment, the output motor 503 starts and drives the blade assembly 504 to rotate. When the blade assembly 504 rotates, it performs air extraction. During air extraction, the fumes generated during the welding of the steel pipe 4 to be welded are removed, preventing workers from inhaling the welding fumes and thus ensuring the safety of workers during the work.

[0030] The working principle of this utility model is as follows: During welding, the two steel pipes 4 to be welded are placed on the two lower limit plates 301 on both sides. After placement, the handwheel 305 is rotated. When the handwheel 305 rotates, it drives the threaded rod 304 to rotate. After the threaded rod 304 rotates, the handwheel 305 drives the upper limit plate 303 to move downward. After the handwheel 305 moves downward, it clamps and fixes the steel pipes 4 to be welded with the lower limit plate 301.

[0031] Once the position of the steel pipe 4 to be welded is fixed, the servo motor 202 starts and drives the rotating shaft 203 to rotate. When the rotating shaft 203 rotates, it drives the output gear 204 to rotate. When the output gear 204 rotates, it drives the gear ring 206 on the side to rotate. When the gear ring 206 rotates, it drives the fixing mechanism 3 to rotate as a whole through the connecting rod 209. When the fixing mechanism 3 rotates as a whole, it drives the steel pipe 4 to be welded inside it to rotate. The steel pipe 4 to be welded rotates automatically as welding progresses, improving welding efficiency.

[0032] During welding, the output motor 503 starts and drives the blade assembly 504 to rotate. When the blade assembly 504 rotates, it performs air extraction. During air extraction, the fumes generated during the welding of the steel pipe 4 are removed, preventing workers from inhaling the welding fumes and thus ensuring the safety of workers during the work.

[0033] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
