Among them, track-mounted welding robots have been widely used and recognized in pipeline welding tasks due to their excellent performance stability, outstanding operation repeatability, simple installation and debugging process, and relatively low cost. This type of structural robot not only ensures high precision and consistency of the welding process, but also significantly improves work efficiency and reduces labor costs, becoming the preferred solution in the field of pipeline welding.

[0003] Existing pipeline welding requires manual work to connect two pipelines to corresponding positions. This process takes a lot of time and has certain errors, which affects construction efficiency.

[0004] In view of this, this application is hereby made. Utility Model Content

[0007] The pipeline docking mechanism includes a fixed ring rotatably mounted on the inner wall of the shell, a first gear is fixedly mounted on the outer wall of the fixed ring, a second telescopic frame is fixedly mounted on the inner wall of the fixed ring, a first motor is fixedly mounted on the middle part of the second telescopic frame, a third gear is rotatably mounted on the top of the first motor, a support frame is fixedly mounted on the end of the second telescopic frame away from the fixed ring, a second gear is rotatably mounted on the support frame and the third gear are located on the same horizontal line, a second rotating wheel is rotatably mounted at the center of the support frame, the second gear is fixedly connected to the second rotating wheel, the first telescopic frame is fixedly mounted on the upper and lower ends of the support frame, the first rotating wheel is rotatably mounted on the end of the first telescopic frame away from the second rotating wheel, and the first rotating wheel and the second rotating wheel are located on the same horizontal plane.

[0008] Furthermore, a fixing block is fixedly mounted on one end of the first telescopic frame away from the fixing ring, and a window for the first rotating wheel to penetrate is provided on the surface of the fixing block.

[0009] Furthermore, a clamping ring is fixedly mounted on the inner wall of the shell, a sliding groove is provided on the surface of the fixing ring, and the clamping ring is rotatably connected to the sliding groove.

[0010] Furthermore, a reciprocating mechanism is fixedly installed on the inner wall of the outer shell;

[0011] The reciprocating mechanism includes a fixed column fixedly installed on the inner wall of the outer shell. Two incomplete gears are rotatably installed on the outer wall of the fixed column. A fifth gear is fixedly installed at one end of the incomplete gear away from the outer shell. The fifth gear meshes with a fourth gear. A second motor is rotatably installed at one end of the fourth gear away from the fifth gear.

[0012] Furthermore, a second support column is fixedly installed on the surface of the base, and a bearing column is fixedly installed at the top of the second support column.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the control box is started, it synchronously drives the first motor and the second motor to rotate. The operation of the first motor drives the rotation of the third gear, and then drives the second gear to rotate through the meshing relationship. At this time, the user introduces the two pipelines to be butted into the butting mechanism respectively. As the pipelines gradually enter, the outer wall of the pipeline will squeeze the first runner, and the squeezing force causes the first runner to contact and start to rotate with the second runner. This rotational movement will effectively drive the pipeline to move forward until the two pipelines are completely butted. At the same time, the meshing rotation of the fourth gear and the fifth gear drives the two incomplete gears to rotate, ensuring the reciprocating circular motion of the pipeline butting mechanism. The entire butting process does not require manual intervention, realizing full automation, improving the efficiency and accuracy of pipeline welding, and reducing the complexity of manual operation.

[0027] Refer to Figure 3A fixing block 6 is fixedly mounted on one end of the first telescopic frame 8 away from the fixing ring 4. A window for the first rotating wheel 7 to penetrate is provided on the surface of the fixing block 6. The first rotating wheel 7 can penetrate the fixing block 6 without any obstacles, thereby ensuring that it can rotate freely.

[0028] See also Figures 5-6 A clamping ring 22 is fixedly installed on the inner wall of the shell 3, and a sliding groove 23 is opened on the surface of the fixed ring 4. The clamping ring 22 is rotatably connected with the sliding groove 23, providing stable support and guidance for the fixed ring 4. During the rotation of the fixed ring 4, it is prevented from deflecting or shaking, thereby ensuring the stability and accuracy of the entire pipeline docking mechanism.

[0029] See also Figure 4 , a reciprocating mechanism is fixedly mounted on the inner wall of the housing 3;

[0030] The reciprocating mechanism includes a fixed column 16 fixedly mounted on the inner wall of the outer shell 3, and two incomplete gears 17 are rotatably mounted on the outer wall of the fixed column 16. A fifth gear 26 is fixedly mounted on the end of the incomplete gear 17 away from the outer shell 3, and the fifth gear 26 is meshed with a fourth gear 18. A second motor 19 is rotatably mounted on the end of the fourth gear 18 away from the fifth gear 26, thereby realizing the reciprocating motion of the pipeline docking mechanism and preventing the excessive winding of the wires 15 from causing failure of the overall device.

[0031] See also Figure 1 A second support column 20 is fixedly installed on the surface of the base 1, and a bearing column 21 is fixedly installed on the top of the second support column 20, which can ensure the stability and firmness of the entire structure, so that the equipment can maintain an accurate position and angle during welding.

[0032] See also Figure 4 A welding head 24 is fixedly installed at one end of the supporting column 21 facing the pipeline, and the welding head 24 is located between the two shells 3, so that the two welding heads 24 can fully weld the pipeline during the rotation process.

[0033] See also Figure 1 A control box 25 is fixedly mounted on the surface of the base 1, and the control box 25 is fixedly connected to the wire 15. One end of the wire 15 away from the control box 25 is fixedly connected to the first motor 12. The control box 25 is convenient for controlling the internal components of the device.

[0034] See also Figure 3 The first rotating wheel 7 and the second rotating wheel 9 are made of wear-resistant rubber, and their surfaces are provided with integrally formed anti-skid patterns. After the two pipes are butt-jointed, the two rotating wheels will slip under a certain force to protect the motor from overload damage.

[0035] Working principle: Start the control box 25 on the base 1, drive the second motor 19 to work through the wire 15, and then drive the fourth gear 18 to rotate. The fourth gear 18 meshes with and rotates the two fifth gears 26, driving the two incomplete gears 17 to rotate. The incomplete gears 17 mesh with the first gear 5 to make the fixed ring 4 rotate reciprocally. At the same time, drive the first motor 12 to work, driving the second gear 10 and the second runner 9 to rotate synchronously. The user introduces the pipe to be docked into the docking mechanism. The outer wall of the pipe presses the first runner 7, and the first runner 7 presses against the second runner 9 to make the first runner 7 rotate, driving the pipe to move forward and promoting the precise docking of the pipe. The clamping ring 22 on the inner wall of the housing 3 is connected to the chute 23 on the fixed ring 4 to ensure the stable rotation of the fixed ring 4. When the pipe is docked, the entire pipe makes a reciprocating circular motion. After the docking is completed, operate the welding head 24 for welding operation to ensure the complete welding of the pipe ends. After the welding is completed, directly extract the pipe. The manual docking process is avoided throughout the process, improving the welding efficiency.
