Description
Technical Field
[0001] The utility model relates to the technical field of pipeline welding, in particular to a pipeline welding alignment device. Background Technique
[0002] A pipeline refers to a device connected by pipes, pipe connectors, valves, etc. for transporting gases, liquids or fluids with solid particles. Usually, after the fluid is pressurized by a blower, compressor, pump, boiler, etc., it flows from the high-pressure part of the pipeline to the low-pressure part, or it can also be transported by the pressure or gravity of the fluid itself. The uses of pipelines are very extensive, especially metal pipelines, which are widely used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. Generally, when the laying length of a pipeline is insufficient, adjacent pipelines are welded and fixed to extend the pipeline.
[0003] However, the shape of the pipeline is circular. During the welding process of the pipeline, the pipeline is prone to rolling, resulting in a situation where there are height differences and misaligned axes between the ports of the two pipelines, thereby affecting pipeline welding. Therefore, it does not meet the existing requirements, and for this reason, we propose a pipeline welding alignment device. Content of the Utility Model
[0004] The purpose of the utility model is to provide a pipeline welding alignment device to solve the problems raised in the above background technique, that is, the shape of the pipeline is circular, and during the welding process of the pipeline, the pipeline is prone to rolling, resulting in a situation where there are height differences and misaligned axes between the ports of the two pipelines, thereby affecting pipeline welding.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A pipeline welding alignment device includes a base. Symmetrical grooves are provided on the front and rear sides of the upper end of the base. A bottom plate is movably connected between the two sides of the upper ends of the two grooves through connecting blocks. Mounting seats are fixedly connected to the upper ends of the two bottom plates. Connecting rods are fixedly connected to both sides of the upper ends of the mounting seats. A top plate is fixedly connected between the tops of the two connecting rods on both sides. Below the top plate and on the upper end of the mounting seat, a clamping seat is movably connected. Support seats are fixedly connected to the upper ends of the sides of the two bottom plates close to each other.
[0006] Preferably, a bidirectional threaded rod is driven and connected by a motor inside one of the grooves, and a sliding rod is fixedly connected inside the other groove.
[0007] Preferably, one of the connecting blocks is threadedly connected to the outer surface of the bidirectional threaded rod, and the other connecting block is slidably connected to the outer surface of the sliding rod.
[0008] Preferably, both ends of the card seat are slidably connected to the outer surface of the connecting rod, and the upper end of the card seat is rotatably connected to a threaded rod through a rotating shaft, and the threaded rod threadedly penetrates and extends to the upper end of the top plate.
[0009] Preferably, rotating grooves are respectively formed inside the opposite sides of the mounting seat and the card seat, and rollers extending to the outside of the rotating grooves are rotatably connected inside the rotating grooves.
[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0011] In the present utility model, one ends of two sections of pipelines to be welded respectively penetrate between the mounting seat and the card seat, and the welding ends are placed in the middle of the upper end of the support seat. Then, the threaded rod is rotated, so that the threaded rod is threadedly rotatably connected to the top plate, and the card seat is pushed to move along the outer surface of the connecting rod towards the side of the mounting seat until the inner side of the card seat is tightly attached to the outer surface of the pipeline, thereby completing the limit fixation of the pipeline. Then, the motor is started to drive the bidirectional threaded rod to rotate. While the bidirectional threaded rod rotates, the connecting blocks on both sides of the outer surface are driven to rotate threadedly, and under the sliding limit of the other connecting block on the outer surface of the sliding rod, the bottom plates fixed with pipelines on both sides are driven to approach and butt against each other, thereby facilitating the welding between the pipelines.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0017] Please refer to Figures 1 to 3, an embodiment provided by the present utility model: a pipeline welding alignment device, including a base 1. Symmetrical grooves 101 are provided on both the front and rear sides of the upper end of the base 1. A bottom plate 6 is movably connected between the two sides of the upper ends of the two grooves 101 through a connecting block 5. Mounting seats 7 are fixedly connected to the upper ends of the two bottom plates 6. Connecting rods 8 are fixedly connected to both sides of the upper ends of the mounting seats 7. A top plate 9 is fixedly connected between the tops of the two connecting rods 8. Below the top plate 9 and movably connected to the upper end of the mounting seat 7 is a clamping seat 10. Support seats 14 are fixedly connected to the upper ends of the sides of the two bottom plates 6 where they are close to each other.
[0018] Both ends of the clamping seat 10 are slidably connected to the outer surface of the connecting rod 8. The upper end of the clamping seat 10 is rotatably connected to a threaded rod 11 through a rotating shaft, and the threaded rod 11 threadedly penetrates and extends to the upper end of the top plate 9. By respectively penetrating one end of the two pipelines to be welded between the mounting seat 7 and the clamping seat 10, and making the welding end be placed in the middle of the upper end of the support seat 14, then rotating the threaded rod 11, the threaded rod 11 is threadedly rotated and connected to the top plate 9, and the clamping seat 10 is pushed to move along the outer surface of the connecting rod 8 towards one side of the mounting seat 7 until the inner side of the clamping seat 10 is tightly attached to the outer surface of the pipeline, thereby completing the limit fixation of the pipeline.
[0019] A bidirectional threaded rod 3 is driven and connected by a motor 2 inside one side groove 101, and a sliding rod 4 is fixedly connected inside the other side groove 101. One side connecting block 5 is threadedly connected to the outer surface of the bidirectional threaded rod 3, and the other side connecting block 5 is slidably connected to the outer surface of the sliding rod 4. Rotating grooves 12 are provided inside the opposite sides of the mounting seat 7 and the clamping seat 10, and rollers 13 extending to the outside of the rotating grooves 12 are rotatably connected inside the rotating grooves 12.
[0020] Start the motor 2 to drive the bidirectional threaded rod 3 to rotate. While the bidirectional threaded rod 3 rotates, it drives the connecting blocks 5 on both sides of its outer surface to rotate threadedly, and drives the two bottom plates 6 fixed with pipelines to approach and butt against each other under the sliding limit of the other side connecting block 5 on the outer surface of the sliding rod 4, thereby facilitating the welding between the pipelines. And through the setting of the rollers 13, it is convenient to rotate the pipeline, so as to weld the whole circumference of the pipeline.
[0021] When the pipeline welding device is in use, one end of two pipelines to be welded respectively passes through between the mounting seat 7 and the clamping seat 10, and the welding ends are placed in the middle of the upper end of the support seat 14. Then, the threaded rod 11 is rotated, so that the threaded rod 11 is threadedly rotatably connected to the top plate 9, and the clamping seat 10 is pushed to move along the outer surface of the connecting rod 8 towards one side of the mounting seat 7 until the inner side of the clamping seat 10 is tightly attached to the outer surface of the pipeline, thus completing the limit fixation of the pipeline. Then, the motor 2 is started to drive the bidirectional threaded rod 3 to rotate. While the bidirectional threaded rod 3 rotates, the connecting blocks 5 on both sides of the outer surface are threadedly rotated, and under the sliding limit of the other connecting block 5 on the outer surface of the sliding rod 4, the bottom plates 6 fixed with the pipelines on both sides are driven to approach and butt against each other, thus facilitating the welding between the pipelines. And through the arrangement of the rollers 13, it is convenient to rotate the pipeline, so as to weld the whole circumference of the pipeline.
