A steel pipe splicing and welding support device

Abstract

This utility model discloses a steel pipe splicing and welding support device, belonging to the field of steel pipe support technology. It solves the problem that if two steel pipes cannot achieve the same horizontal height and coaxial alignment, the final welded steel pipes will lack good consistency, leading to incompatibility in final applications. The device includes a fixed base, sliding blocks located on both sides of the fixed base that can move towards or away from each other, a clamping assembly rotatably mounted on the fixed base, and a limiting assembly fixedly connected to the sliding blocks. In operation, the two steel pipes are first inserted into the clamping assembly to achieve coaxiality and the same horizontal height. Then, the side cylinder and the limiting assembly are brought closer together. The side cylinder adjusts its height so that the steel pipe passes through the limiting space and is tangent to the inclined rod. The drive cylinder moves the intermediate plate and the side limiting rod downwards, adjusting the radius of the inscribed circle in the limiting space to restrict the steel pipe. The drive motor rotates forward, the side cylinder rises, and the end faces of the two steel pipes are aligned, facilitating welding.

Description

Technical Field

[0001] This utility model relates to the field of steel pipe support technology, and in particular to a steel pipe splicing and welding support device. Background Technology

[0002] Steel pipe splicing and welding is a process of joining multiple or different types of steel pipes together in a specific way and then welding them. First, the steel pipes to be joined are precisely butted or arranged according to design requirements, and clamps, tack welding, or other methods are used to fix the pipes in place to ensure splicing accuracy and stability. Then, based on parameters such as the material and thickness of the steel pipes, a suitable welding method is selected, such as manual electric arc welding, gas shielded welding, or submerged arc welding, and the weld area is preheated.

[0003] Currently, the most difficult part of splicing and welding two steel pipes is to set them at the same horizontal level and achieve coaxial connection. If the two steel pipes cannot meet the requirements of being at the same horizontal level and coaxially connected, the welded steel pipes will not have good consistency and will be incompatible in the final application.

[0004] Therefore, a steel pipe splicing and welding support device is proposed to solve or alleviate the above problems. Utility Model Content

[0028] A steel pipe splicing and welding support device, such as Figures 1 to 3 As shown, the system includes a track 1, a drive motor 2 fixedly connected to one end of the track 1, a double-threaded lead screw 3 fixedly connected to the rotor shaft of the drive motor 2, a lead screw nut 4 threadedly connected to the two threads of the double-threaded lead screw 3, a fixed seat 6, slides 5 located on both sides of the fixed seat 6 that can move towards or away from each other, a clamping assembly rotatably mounted on the fixed seat 6, and a limiting assembly fixedly connected to the slides 5. The limiting assembly contains a limiting space that can accommodate the steel pipe, and the radius of the inscribed circle of the limiting space is adjustable. The fixed seat 6 is fixedly connected to the track 1, and the double-threaded lead screw 3 passes through the fixed seat 6. The slides 5 are slidably connected to the track 1, and the slides 5 are fixedly connected to the lead screw nut 4.

[0029] A rotary cylinder 7 is fixedly connected to the fixed base 6. A clamping assembly is fixedly connected to the movable end of the rotary cylinder 7. The clamping assembly includes an intermediate cylinder 8, a rod sleeve 9 fixedly connected to the intermediate cylinder 8 and sleeved on the outside of the piston rod in the intermediate cylinder 8, two lower clamping rods 14 fixedly connected to the outer ring of the rod sleeve 9 and arranged centrally symmetrically, and an upper clamping rod 12 fixedly connected to the outer ring of the piston rod in the intermediate cylinder 8 and located directly above the lower clamping rods 14. A top sleeve 10 is fixedly connected to the top of the piston rod in the intermediate cylinder 8. Two centrally symmetrically arranged top connecting cylinders 11 are fixedly connected to the outer ring of the top sleeve 10. The end of the upper clamping rod 12 is embedded in the top connecting cylinder 11. A lower connecting cylinder 13 located below the top connecting cylinder 11 is fixedly connected to the outer ring of the rod sleeve 9. The end of the lower clamping rod 14 is embedded in the lower connecting cylinder 13.

[0030] The horizontal height of the limiting space is adjustable. A side cylinder 15 is fixedly connected to the top surface of the slide block 5. The limiting component is installed on the piston rod in the side cylinder 15 to adjust the horizontal height of the limiting space. The limiting component includes a connecting seat 17 fixedly connected to the piston rod in the side cylinder 15 through a connecting sleeve 16, two inclined rods 18 that are obliquely fixedly connected to the connecting seat 17 through a reinforcing member 19 and are symmetrically arranged, a top plate 20 fixedly connected between the upper ends of the two inclined rods 18, a driving cylinder 21 fixedly connected to the top surface of the top plate 20, an intermediate plate 22 located between the two inclined rods 18, and side limiting rods 23 located on both sides of the two inclined rods 18 and fixedly connected to the intermediate plate 22. The piston rod in the driving cylinder 21 passes through the top plate 20 and is fixedly connected to the intermediate plate 22. A limiting space is formed between the inclined rods 18 and the side limiting rods 23.

[0031] In actual operation, the operator first inserts two steel pipes into the outer side of the upper clamping rod 12. Then, the middle cylinder 8 controls its piston rod to descend, causing the top sleeve 10 and top connecting cylinder 11 on the piston rod to move the upper clamping rod 12 and the steel pipe downwards until the upper clamping rod 12 and the lower clamping rod 14 clamp the inner and outer rings of the steel pipe. At this time, the steel pipe, the upper clamping rod 12, and the lower clamping rod 14 are tangent at the lowest point of the steel pipe, and the steel pipes on both sides can maintain a coaxial arrangement. Then, the drive motor 2 is started, which drives the double threaded screw 3 to rotate, so that the slides 5 on both sides can drive the side cylinder 15 and the limiting assembly to move towards each other. The side cylinder 15 adjusts the horizontal height of the limiting space in the limiting assembly to ensure that when the limiting assemblies on both sides come together, the steel pipe passes smoothly through the limiting space. Then, the horizontal height of the limiting assembly is adjusted again by the side cylinder 15, so that the two steel pipes can move towards each other. The diagonal bar 18 can also be tangent to the outer ring of the steel pipe. At this time, the drive cylinder 21 drives the intermediate plate 22 and the side limit rod 23 to move downward, thereby adjusting the size of the inner circle radius of the limit space, so that the steel pipe is restricted. Then the clamping component releases the clamping action on the steel pipe, and the drive motor 2 rotates in the opposite direction, so that the slides 5 on both sides drive the two steel pipes to move backward through the limit component and get out of the restriction of the clamping component. The clamping component can also ensure that it will not obstruct the approach of the limit components on both sides by following the rotation of the rotary cylinder 7. Then the drive motor 2 rotates forward again, so that the limit components on both sides approach each other. During this process, the side cylinders 15 on both sides rise synchronously, so that the end faces of the two steel rods can be directly aligned without being restricted by the intermediate clamping component. Finally, after the end faces of the two steel pipes touch each other, they are aligned with each other, not only at the same horizontal height, but also in a coaxial state, so as to facilitate the welding action.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. 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.
