Description

Technical Field

[0001] This invention relates to the field of steel pipe welding technology, specifically to a large-diameter steel pipe welding equipment. Background Technology

[0002] Steel pipes, with their hollow cross-section, are widely used as pipelines for transporting fluids such as oil, natural gas, coal gas, water, and certain solid materials. Compared to solid steel materials like round bars, steel pipes are lighter in weight while maintaining the same bending and torsional strength, making them an economical cross-section steel material. They are widely used in manufacturing structural components and mechanical parts, such as oil drill pipes, automobile drive shafts, bicycle frames, and steel scaffolding used in construction. Using steel pipes to manufacture ring-shaped parts improves material utilization, simplifies manufacturing processes, and saves materials and processing time. Examples include rolling bearing rings and jack sleeves, which are widely made from steel pipes. Steel pipes are also an indispensable material for various conventional weapons; gun barrels and cannon barrels are all made from steel pipes.

[0003] Most existing steel pipe welding equipment uses handheld welding torches, which increases the burden on workers and poses a high risk. In addition, the workbench needs to be flipped or the fixed square tubes need to be disassembled and re-fixed in order to weld the four sides of the junction of the two square tubes. The process is cumbersome and the welding efficiency is low. Furthermore, impurities on the surface can easily affect the welding work during the welding process, and the welding debris can cause injury to workers. It cannot meet the needs of users.

[0014] As a further explanation of the present invention, the positioning components are configured in two sets.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention utilizes a drive gear that rotates via a motor, which in turn drives a connecting gear. This rotation, in turn, drives the mounting gear via a connecting rod, ultimately rotating the threaded shaft inside the transmission gear. This rotation of the threaded shaft allows for the adjustment of the mounting block on the slide rail bracket, facilitating adjustments based on the diameter of the welded rebar. The first positioning plate, under the action of a second hydraulic rod, extends and retracts to position and fix the welded steel pipe, preventing misalignment. The second positioning plate, with the assistance of a second damping spring and a damper, provides shock absorption and cushioning against impacts during positioning, preventing wear on the steel pipe. Furthermore, the inner wall of the second positioning plate is evenly equipped with connecting rollers to reduce friction during the rotation of the steel pipe, further preventing wear and misalignment during welding.

[0017] The connecting plate, through the first shock-absorbing spring, damper, and fixed plate, provides a certain degree of shock absorption and buffering, which helps to avoid direct force damage to the steel pipe when clamping it. Then, the installed drive shaft drives the rotation of the push plate to fix the clamped steel pipe. This allows for rotation of the steel pipe during welding at the joint, facilitating adjustment of the welding position and improving the automatic sliding function of the equipment, thereby increasing welding efficiency.

[0018] The welding shell is raised and lowered by the third hydraulic rod, and then the welding gun is raised and lowered by the fourth hydraulic rod through the welding block to perform a certain welding action on the outer surface of the steel pipe. When the welding shell is raised and lowered, the protective shell slides inside the slide shell under the compression of the connecting spring, which facilitates a certain protection during the welding process and avoids the debris generated during welding from causing injury to the workers.

[0019] When the electric push rod is extended and retracted, the cleaning bracket is rotatably connected to the first rotating shaft, the electric push rod, and the second rotating shaft. This allows for angle adjustment of the cleaning bracket via the connecting shafts, thus enabling the adjustment of the brush bracket's angle. This facilitates the cleaning of dust from the surface of the steel pipe during the rotating welding process, preventing impurities from affecting the welding work. Furthermore, the brush bracket is connected by a spring, which helps to prevent wear during cleaning when the brush bracket is in motion. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: a large-diameter steel pipe welding equipment, comprising: a working platform 1 and a connecting slide rail 2, the working platform 1 having a connecting slide rail 2 on its side wall, a threaded rod 3 installed inside the connecting slide rail 2, a pusher bracket 4 installed on the outer surface of the threaded rod 3, a rotating component 5 installed at the front end of the pusher bracket 4, a drive component 7 installed at the center of the side wall of the working platform 1, a fixed bracket 9 installed at the upper end of the drive component 7, a welding bracket 10 installed on the inner wall of the fixed bracket 9, a third hydraulic rod 11 installed inside the welding bracket 10, and a welding component 12 installed at the lower end of the third hydraulic rod 11.

[0033] In this embodiment, the threaded rod 3 is rotated by a motor, which enables the installed jacking bracket 4 to slide inside the connecting slide rail 2. This facilitates the pushing of the steel pipe to be welded, allowing the steel pipe to be pushed to the designated position for welding. This achieves automated operation of the equipment, improves work efficiency, and saves manpower.

[0034] Next, the rotating assembly 5 includes a mounting housing 501, a main gear 502, an auxiliary gear 503, and a drive shaft 504. The mounting housing 501 is installed at the end of the push bracket 4. The main gear 502 is installed inside the mounting housing 501. The auxiliary gear 503 is meshed inside the main gear 502. The drive shaft 504 is installed inside the auxiliary gear 503. The push assembly 6 is installed at the end of the drive shaft 504. The mounting housing 501 drives the sliding of the push bracket 4. The main gear 502 is driven by the motor to rotate the auxiliary gear 503, thereby rotating the drive shaft 504.

[0035] It should be noted that the main gear 502 is smaller than the auxiliary gear 503. When the main gear 502 rotates, the two gears with different diameters mesh together and rotate. The gear with the larger diameter will rotate slower than the gear with the smaller diameter. Their rotation speed ratio is inversely proportional to the gear diameter, which improves the stability of the welded steel pipe.

[0038] The installed drive shaft 504 drives the rotation of the push plate 601, enabling the steel pipe to rotate during clamping. The installed fixing plate 604 is raised and lowered by the first hydraulic rod 603 and the support plate 602. The fixing plates 604 are arranged in four groups to fix the steel pipe to be welded.

[0039] In this embodiment, the installed fixing plate 604 is raised and lowered by the first hydraulic rod 603 and the support plate 602. Four sets of fixing plates 604 are used to fix the steel pipe to be welded. The connecting plate 606, through the first shock-absorbing spring 605, works with the damper and fixing plate 604 to provide shock absorption and buffering, preventing direct force damage to the steel pipe during clamping. The installed drive shaft 504 drives the rotation of the push plate 601 to fix the clamped steel pipe. The threaded rod 3 rotates via a motor, allowing the installed push bracket 4 to slide within the connecting slide rail 2, facilitating the pushing of the steel pipe to the designated position for welding. This automates the equipment, improves efficiency, and saves manpower. The installed housing 501 drives the sliding of the push bracket 4, and the motor drives the main gear 502 to rotate the auxiliary gear 503.

[0040] This enables the drive shaft 504 to rotate, and the finally installed drive shaft 504 drives the top push plate 601 to rotate, thereby fixing the clamped steel pipe. This facilitates the rotation of the steel pipe during welding at the joint, allowing for adjustment of the welding position and improving the automatic sliding function of the equipment, thus increasing welding efficiency.

[0042] In this embodiment, the threaded rod 3 is rotated by a motor, which enables the installed jacking bracket 4 to slide inside the connecting slide rail 2. This facilitates the pushing of the steel pipe to be welded, allowing the steel pipe to be pushed to the designated position for welding.

The main gear 502 is driven by the motor to rotate the auxiliary gear 503, thereby rotating the drive shaft 504.

[0044] It should be noted that the main gear 502 is smaller than the auxiliary gear 503. When the main gear 502 rotates, the two gears with different diameters mesh together and rotate. The gear with the larger diameter will rotate slower than the gear with the smaller diameter.

The second positioning plate 805 is mounted on the end of the second damping spring 804. The connecting roller shaft 806 is mounted on the inner wall of the second positioning plate 805.

[0062] Positioning component 8 is set to two groups.

[0063] The rotation of the threaded shaft 708 allows for the lifting and lowering adjustment of the mounting block 801 on the slide rail bracket 701, facilitating adjustment based on the diameter of the welded reinforcing bar. The first positioning plate 803, under the action of the second hydraulic rod 802, extends and retracts, providing positioning and fixing for the welded steel pipe, preventing displacement. The second positioning plate 805, through the second damping spring 804 and damper, provides shock absorption and buffering for the first positioning plate 803, preventing wear on the steel pipe during positioning upon impact. Furthermore, the inner wall of the second positioning plate 805 is evenly equipped with connecting rollers 806, reducing friction during steel pipe rotation and preventing wear and displacement during welding.

[0064] The welding assembly 12 includes a welding shell 1201, a fourth hydraulic rod 1202, a welding block 1203, a welding gun 1204, a chute shell 1205, a connecting spring 1206, and a protective shell 1207. The welding shell 1201 is installed at the end of the third hydraulic rod 11, the fourth hydraulic rod 1202 is installed at the lower end of the welding shell 1201, the welding block 1203 is installed at the end of the fourth hydraulic rod 1202, the welding gun 1204 is installed at the end of the welding block 1203, the chute shell 1205 is installed at the front end of the welding shell 1201, the connecting spring 1206 is installed inside the chute shell 1205, the protective shell 1207 is installed at the end of the connecting spring 1206, and a cleaning assembly 13 is installed on the front wall of the welding shell 1201.

[0065] The welding shell 1201 is raised and lowered by the third hydraulic rod 11. Then, the welding gun 1204 is raised and lowered by the fourth hydraulic rod 1202 via the welding block 1203 to perform a certain welding action on the outer surface of the steel pipe. When the welding shell 1201 is raised and lowered, the protective shell 1207 slides inside the slide shell 1205 under the compression of the connecting spring 1206, which facilitates a certain protective action during the welding process and avoids the debris generated during welding from causing injury to the workers.

[0066] The cleaning assembly 13 includes a connecting shaft 1301, a cleaning bracket 1302, a first rotating shaft 1303, an electric push rod 1304, a second rotating shaft 1305, a mounting spring 1306, and a brush bracket 1307. The connecting shaft 1301 is mounted on the front wall of the welded housing 1201. The cleaning bracket 1302 is mounted on the outer surface of the connecting shaft 1301. The first rotating shaft 1303 is mounted on the inner wall of the cleaning bracket 1302. The electric push rod 1304 is mounted inside the first rotating shaft 1303. The second rotating shaft 1305 is mounted at the end of the electric push rod 1304. The mounting spring 1306 is mounted at the front end of the cleaning bracket 1302. The brush bracket 1307 is mounted at the end of the mounting spring 1306.

[0067] The cleaning components 13 are configured in two groups, and the two groups of cleaning components 13 are symmetrically distributed about the welding shell 1201.

[0068] During welding, the electric push rod 1304 extends and retracts, and the cleaning bracket 1302 is rotatably connected to the first rotating shaft 1303, the electric push rod 1304, and the second rotating shaft 1305. This allows the cleaning bracket 1302 to be adjusted at a certain angle via the connecting shaft 1301, thereby adjusting the angle of the brush bracket 1307. This facilitates the cleaning of dust from the surface of the steel pipe during the rotating welding process, preventing impurities from affecting the welding work. Furthermore, the brush bracket 1307 is connected via a spring 1306, which helps prevent wear during cleaning when the brush bracket 1307 is in motion.

[0069] In this embodiment, during equipment use, the third hydraulic rod 11 drives the lifting and lowering of the welding shell 1201. Then, the welding gun 1204, via the welding block 1203, moves up and down on the fourth hydraulic rod 1202 to perform welding on the outer surface of the steel pipe. While the welding shell 1201 is lifting, the protective shell 1207 slides within the sliding groove shell 1205 under the compression of the connecting spring 1206, providing protection during welding and preventing injury to workers from welding debris. Finally, during welding, the installed electric push rod... When 1304 is in the telescopic action, the cleaning bracket 1302 is rotatably connected to the first rotating shaft 1303, the electric push rod 1304 and the second rotating shaft 1305, so that the cleaning bracket 1302 can be adjusted at a certain angle through the connecting shaft 1301, thereby realizing the angle adjustment of the brush bracket 1307. This facilitates the cleaning of dust on the surface of the steel pipe during the rotational welding action, and avoids the influence of impurities contained in the welding on the welding work. In addition, the brush bracket 1307 is connected by the installed spring 1306, which facilitates the movement of the brush bracket 1307 and avoids wear during cleaning.

[0070] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
