[0001] This utility model relates to the field of steel pipe welding technology, specifically a chain-type multi-diameter integrated welding machine for steel pipes. Background Technology

[0002] Steel pipes are hollow steel pipes whose length is much greater than their diameter or circumference. They are classified by cross-sectional shape into round, square, rectangular, and irregularly shaped steel pipes; by material into carbon structural steel pipes, low-alloy structural steel pipes, alloy steel pipes, and composite steel pipes; by application into pipes for transportation, engineering structures, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, and high-pressure equipment; and by manufacturing process into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled (drawn) types, while welded steel pipes are divided into straight-seam welded steel pipes and spiral-seam welded steel pipes.

The process requires personnel to constantly adjust their position, which is cumbersome and unsafe. Therefore, a chain-type multi-diameter integrated butt jointing machine for welding steel pipes is designed to solve the existing shortcomings. Utility Model Content

Convex blocks are fixedly connected to the bottom of both adjusting plates 8, and both convex blocks are disposed inside the convex groove 100 and slidably connected to the base 1. Two rotating rods 9 are provided between the two adjusting plates 8, with both ends of the two rotating rods 9 passing through the two adjusting plates 8 and the two fixed plates 7 respectively. Both rotating rods 9 are slidably connected to the two adjusting plates 8 and the two fixed plates 7. 7. Rotary connection: Both ends of the outer side of the two rotating rods 9 are fixedly connected to the first gear 11. The outer side of the first gear 11 is meshed with two second gears 12. A rotating column 13 is fixedly connected to one side of the second gear 12. The rotating column 13 passes through the fixed plate 7 and is rotatably connected to the fixed plate 7. A rotating cylinder 14 is slidably connected to one end of the rotating column 13. A sliding groove 16 is opened on the outer side of the rotating column 13. A limiting slide bar 17 is fixedly connected to the inner side of the rotating cylinder 14. The limiting slide bar 17 is set inside the sliding groove 16 and is slidably connected to the rotating column 13. One end of the rotating cylinder 14 passes through the adjusting plate 8 and is rotatably connected to the adjusting plate 8. A conical seat 15 is fixedly connected to one end of the rotating cylinder 14. A second sprocket 10 is connected to one end of the outer side of the two rotating rods 9. The two second sprockets 10 are connected by chain drive. A drive structure is provided between the two second sprockets 10. A transmission structure is provided between the two bidirectional screws 2.

[0023] The drive structure includes two third sprockets 18 and two fourth sprockets 19. The two third sprockets 18 are fixedly connected to one end of two rotating rods 9, and the two fourth sprockets 19 are located outside the two third sprockets 18. The two third sprockets 18 are connected to the two fourth sprockets 19 via chain drive. The drive structure also includes two rotating rods 20. The two rotating rods 20 are fixedly connected to the front side of the two fourth sprockets 19, and the outer side of each rotating rod 20 is rotatably connected to a support 21.

A motor is fixedly connected to the front side of the base 1, and the output end of the motor is fixedly connected to one of the third gears 22.

[0024] Specifically, two steel pipes are placed on multiple conical seats 15, and the motor is started. The motor model is not specifically limited, but is based on the compatible equipment.

A support seat is rotatably connected to the outer side of the worm 5. The support seat is fixedly connected to the top of the base 1. A handwheel is installed at the top of the worm 5.

[0027] Specifically, when the handwheel is turned, the worm 5 meshes with the worm wheel 4. The worm wheel 4 drives one of the first sprockets 3 to rotate through one of the double-headed screws 2. One of the first sprockets 3 and the other first sprocket 3 are driven by a chain. The two double-headed screws 2 can rotate simultaneously. The double-headed screws 2 are threadedly connected to two adjusting plates 8. The adjusting plates 8 can drive the rotating cylinder 14 to slide on the rotating column 13, while the convex block slides inside the convex groove 100. This structural design realizes the adjustment of the position of multiple conical seats 15 so that the device can be used with steel pipes of various sizes, thus improving the practicality of the device.
