Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline welding leveling butt joint device. Background Art

[0002] The pipe welding leveling and docking device is a tool used for pipe installation and maintenance. It can accurately align two pipes and keep them level for welding. The use of the pipe welding leveling and docking device can improve the welding efficiency and welding quality of the pipes and reduce the time and cost of pipe installation and maintenance. Most of the existing pipe welding leveling devices require that the pipes on both sides be fixed at the same horizontal height first, and then the leveling device is placed in for welding. Because the outer surface of the pipe is a smooth cylindrical shape, the fixing devices on both sides are easy to fall off or shift, causing the welding process to be interrupted, or one side is in a higher position, causing welding failure. The entire welding process is unstable, and the operation is cumbersome and inconvenient to use. Utility Model Content

[0003] The utility model aims to provide a pipeline welding leveling butt joint device, which solves the technical problems existing in the prior art and achieves the technical effects of improving welding stability and facilitating use.

The fixing components are at the same height in the horizontal direction, and a first pipeline and a second pipeline are provided on the tops of the fixing components on both sides respectively. To improve welding stability, a leveling component is provided on one side of the second pipeline. To fix the pipeline on the other side, connecting components are equidistantly provided along the circumference direction on one side of the leveling component, and the connecting components are used to fix the first pipeline.

DETAILED DESCRIPTION

[0017] In order to make the content of the utility model easier to understand, the technical solutions in the embodiments of the utility model will be described clearly and completely in conjunction with the drawings in the embodiments of the utility model. The same parts are represented by the same figure marks. It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0018] like Figure 1-5 As shown, a pipeline welding leveling and docking device is provided in this embodiment, including: a base 1, support brackets 2 are provided on both sides of the top of the base 1, and a fixing component 3 is provided on the upper end of the support bracket 2. The fixing component 3 is in the same height in the horizontal direction. The setting of the fixing component 3 ensures that the first pipeline 5 and the second pipeline 6 are horizontally fixed before the welding work is carried out, ensuring that the pipelines on both sides are at the same height, reducing welding errors and improving welding accuracy. The tops of the fixing components 3 on both sides are respectively provided with the first pipeline 5 and the second pipeline 6, and a leveling component 4 is provided on one side of the second pipeline 6. Connecting components 7 are equidistantly provided on one side of the leveling component 4 along the circumference direction, and the connecting component 7 is used to fix the first pipeline 5. The combination of the leveling component 4 and the connecting component 7 is used to level and fix the connecting ports of the pipelines on both sides that need to be welded, so that the welding process proceeds smoothly.

[0019] The fixing component 3 specifically includes: a bearing plate 301 and bolts 306; the upper surface of the bearing plate 301 is used to place the pipe, which is arranged on the top of the support bracket 2, and a reserved through hole is opened in the middle position inside, a stopper 303 is provided on one side of the bearing plate 301, the diameter of the stopper 303 is directly adapted to the reserved through hole, and an internal thread is provided inside, and fixing plates 302 are provided on both sides of the bearing plate 301; bolts 306 pass through the reserved through hole to penetrate the fixing plate 3 02 and the limiting member 303, one end of which is connected to the rotating cap 305, and the other end is provided with a clamping plate 304, and the working surface of the clamping plate 304 is provided with a protective pattern. The setting of the anti-slip pattern enables the clamping plate 304 to better fix the smooth outer wall of the pipe. When working, the pipe is placed on the upper surface of the supporting plate 301, and the bolt 306 is driven to rotate inside the limiting member 303 by rotating the rotating cap 305, thereby driving the clamping plate 304 to approach the outer wall of the pipe until it stops when it is close to the outer wall.

[0020] The leveling component 4 specifically includes: a fixing ring 401 and a threaded rod 405; the fixing ring 401 is hinged at one end through a pin 402, and a connecting block 403 is provided on the top of the other end. The top of the connecting block 403 is provided with a groove, and a rotating shaft 404 is provided in the connecting block 403 on one side; the threaded rod 405 is rotatably connected to the rotating shaft 404, and a locking piece 406 is provided on the outside. The fixing ring 401 is hinged to each other through the pin 402. When in use, the construction personnel can open the leveling component 4 with one hand, lock the fixing rings 401 on both sides to the outer wall of the pipeline, rotate the threaded rod 405 into the groove, and fix it by screwing the locking piece 406 on the outer wall, and stop screwing when the locking piece 406 is against the connecting block 403.

[0021] The connecting component 7 specifically includes: an extension plate 701, which is equidistantly arranged along the circumference direction of one side of the fixing ring 401, and a cap bolt 702 is penetrated through the inside of the side away from the fixing ring 401. When working, the extension plate 701 is moved to the outer wall of one side of the pipe, and is fixed by screwing the cap bolt 702 to perform welding.

[0022] When in use, when the construction personnel weld the pipes on both sides, they need to level them to make the welding process smoother. At this time, the first pipe 5 and the second pipe 6 are placed on the upper surface of the bearing plates 301 on both sides, and the bolts 306 are driven to rotate in the limiter 303 by screwing the rotating cap 305, thereby driving the clamping plate 304 to move. When the clamping plate 304 abuts against the outer walls of the first pipe 5 and the second pipe 6, it stops. At this time, the first pipe 5 and the second pipe 6 are at the same horizontal height, and then the fixing ring 401 is opened, and the fixing ring 401 is clamped on the end of the second pipe 6 that needs to be welded, and then the threaded rod 405 is rotated to the inside of the groove, and the position is limited and fixed by screwing the external limiter 303. When the limiter 303 abuts against one side of the connecting block 403, the screwing is stopped, and the extension plate 701 is moved to the end of the first pipe 5 that needs to be welded, and the cap bolt 702 is used to tighten and fix it, so as to carry out the welding work. The setting of the fixing component 3, the leveling component 4 and the connecting component 7 makes the whole welding process more stable, and the device is easy to use.
