Description

Technical Field

[0001] The present invention relates to the technical field of butt joints in pipeline welding, and in particular to a pipeline welding butt joint device for heating engineering and a method of using the same. Background Art

[0002] A pipe welding adapter is a clamp that can align two pipes. Using this clamp, people can easily weld and fix the connection between the two pipes. Pipe welding adapters are used in many pipe connections. For example, in urban heating projects, pipe welding adapters are also needed because the main pipes are relatively thick.

[0003] When using the existing pipe welding joint device for heating projects, a threaded rod is used in combination with a clamping block. The threaded rods on both sides are rotated to allow the clamping blocks to move closer to the pipe and clamp it. Since the threaded rods rotate independently, synchronization cannot be guaranteed, resulting in the ends of the pipes on both sides not being aligned. Moreover, the movement of the clamping blocks on both sides causes the pipes on both sides to not be coaxial after positioning, resulting in deviations in the joint positions between the pipes, which in turn affects the welding of the pipes. Therefore, a pipe welding joint device for heating projects is needed that can solve the existing problems. Summary of the Invention

[0004] In view of this, the present invention provides a pipe welding butt joint for heating engineering, comprising a disc and a centering component;

[0005] The disc is provided with a through hole matching the diameter of the pipe to be docked;

[0006] The centering assembly comprises:

[0007] a driving gear disposed on the front wall of the disc and located beside the through hole;

[0008] The outer gear ring is rotatably mounted on the front wall of the disc, and its inner diameter is consistent with the inner diameter of the through hole.

[0009] It can rotate around the center of the through hole as the center point, and the driving gear is meshed with the outer diameter of the outer gear ring to provide power for the rotation of the outer gear ring. The pipe to be connected can be passed through the through hole and the outer gear ring;

[0010] The synchronous roller assembly includes multiple groups, which are arranged around the outer gear and can move toward the center of the disc through the meshing action of the outer gear ring, so as to adjust and position the pipes to be connected.

[0011] Furthermore, a servo motor is provided on the rear wall of the disc corresponding to the driving gear, an output shaft of the servo motor passes through the disc and extends to the front wall of the disc, and the driving gear is mounted on the output shaft of the servo motor.

[0012] Furthermore, each group of the synchronous roller assemblies includes a transmission gear, a movable shaft, a driving rod and a roller; the movable shaft can be rotatably connected to the front wall of the disc and is located on the outside of the outer gear ring; the transmission gear is fixedly mounted on the outer surface of the movable shaft and can mesh with the outer gear ring; the driving rods form a group of two, one end of each of which is fixedly mounted on the outer surface of the movable shaft; when the outer gear ring rotates, the driving rods are driven to rotate by the meshing action of the transmission gears; the other ends of the two driving rods are rotatably connected to the rollers; the rollers can move closer to the pipe to be docked as the driving rods rotate for adjustment and positioning.

[0013] Furthermore, the movable shaft is also equipped with a supporting frame, which is L-shaped, with one end vertically connected to the disc and the other end connected to the movable shaft, so as to support the movable shaft.

[0014] Furthermore, the synchronous roller assemblies are provided in three groups, which are sequentially arranged around the outer gear ring.

[0015] Furthermore, a groove is provided on the outer surface of the roller, and the groove is arranged around the outer surface of the roller.

[0016] Furthermore, the roller and the groove are both axially aligned with the through hole.

[0017] Furthermore, the width of the groove is adapted to the width of the burr at the joint position of the pipe to be butted along the length direction of the pipe.

[0018] Furthermore, the three groups of synchronous roller assemblies are spaced at equal distances around the outer gear ring.

[0019] The present invention provides a pipe welding adapter for heating projects, which has the following advantages: the welding adapter is provided with a centering component. After the centering component is used, when the servo motor is started, the driving gear drives the outer ring gear to engage and rotate, and the outer ring gear drives the three transmission gears to engage and rotate synchronously, so that multiple drive rods rotate synchronously, and the three rollers move closer to the outer wall of the heating project pipe. The three rollers clamp the heating project pipe to achieve three-point synchronous center positioning, so that the heating project pipes on both sides are on the same axis, ensuring the accuracy of the docking position of the heating project pipes.

[0020] A second aspect of the present invention further provides a method for using a pipe welding adapter for a heating engineering project, comprising:

[0021] Put the disc on the outer surface of one of the heating engineering pipes, pull the other heating engineering pipe, and make the ends of the heating engineering pipes on both sides butt joint;
