[0069] The working principle of the present application is as follows: first, before the device is installed with the pipeline, the second movable plate 42 is driven by the air cylinder 43 to move with the first movable plate 40, so that the lifting plate 2 is lifted to the designated position of the base plate 1 by the main gear ring plate 48 to drive the welding assembly to rise, the hoop plate 18 is opened above the lower supporting plate 16 by the rotating shaft 17, so that the base plate 1 and the welding assembly can be installed at the to-be-welded position of the pipeline, facilitating the contact of the polishing gun or the welding gun 35 on one side with the welding position, after the lower supporting plate 16 is attached to the position below the sewage pipeline, the hoop plate 18 is rotated by the rotating shaft 17, and the clamping column 23 is connected with the wedge-shaped rod 24 through the clamping groove under the action of the clamping column 23 connected to the bottom of the hoop plate 18, so that the clamping column 23 is limited on one side of the wedge-shaped rod 24, and the hoop plate 18 is limited above the lower supporting plate 16 to the outer wall of the sewage pipeline;

[0070] After the hoop plate 18 and the lower supporting plate 16 limit and fix the welding position of the sewage pipeline, the clamping pipe assembly is opened, specifically, the gear plate 6 is driven to rotate by the bidirectional motor 13, and the limiting gear ring 7 is rotated on one side of the top ring 5 under the meshing action of the gear plate 6 and the limiting gear ring 7, so that the limiting gear ring 7 is arranged in parallel on one side of the top ring 5, and the clamping pipe assembly is in the shape of an inverted “U” as a whole.

[0072] After the pipeline is fixed, in order to weld or polish the welding position, the gear column 33 is driven by the corresponding driving motor 34 to move, so that the hanging plate 32 on one side moves on the outer wall of the closed first half gear ring 20 and the second half gear ring 21, so that the hanging plate 32 can drive the polishing gun or the welding gun 35 to weld or polish the pipeline, and under the action of the electric push rod 36 connected to the outer side of the hanging plate 32, the electric push rod 36 on both sides drives the compression joint wheel 38 to compress the joint of the sewage treatment pipeline, so as to ensure the treatment effect of the welding seam before and after welding.

[0073] When the switching of the welding or grinding function is required, the welding assembly connected with the sewage pipeline is first opened, specifically, the worm 30 drives the worm gear 29 to rotate, so that the movable rod 28 drives the convex plate 27 to extrude the wedge-shaped rod 24, so that the reset spring 25 is extruded, and then the wedge-shaped rod 24 slides in the inner wall of the fixed seat 15 without limiting the clamping column 23, so that the hoop plate 18 can be opened above the treatment position of the pipeline, and the welding assembly can be separated from the sewage pipeline;

[0074] After the pipeline is separated from the welding assembly, in order to facilitate the rotation switching of the welding assembly, the cylinder 43 is started to drive the first movable plate 40 to move, and under the action of the first movable plate 40 and the second movable plate 42 in the shape of "X", the plurality of first movable plates 40 and second movable plates 42 drive the lifting plate 2 to move downward, so that the welding assembly can be lowered to the lower side of the bottom plate 1 after being separated from the sewage pipeline for switching, and when switching, the user manually rotates the welding assembly as a whole, so that the fixed seat 15 drives the fixed seat 15 to rotate on the surface of the lifting plate 2 through the main gear ring plate 48, so that the fixed seat 15 drives the welding assembly to switch the position on both sides, realizing the quick rotation switching of the grinding and welding positions of the welding assembly.

[0075] After the position of the welding assembly is switched, in order to realize the connection of the welding assembly after the function switching and the sewage pipeline, the cylinder 43 is powered to drive the lifting plate 2 to move upward, so that the lower supporting plate 16 is connected with the sewage pipeline, which is convenient for connecting the hoop plate 18 with the sewage pipeline, and under the action of the limiting lug, the limiting effect of the lifting position of the welding assembly is realized, the concentric effect with the pipe clamping assembly is ensured, and the connection accuracy with the sewage pipeline is ensured, so that the working principle of the pipeline welding device for the sewage treatment equipment operation and maintenance is completed.

[0076] In summary, in the present application, the pipe clamping assembly is arranged on the welding assembly, so that the pipe clamping assemblies on both sides can position and assist the pulling force of the sewage pipeline on both sides of the leakage point, ensuring the welding stability of the pipeline, and through the flexible sliding and installation of the pipe clamping assembly on the surface of the bottom plate 1, the movement of the device in the welding position is improved, the function of the hanging plate 32 on both sides can be switched according to the welding demand of the user, through such arrangement, the device can realize bidirectional limiting welding on the leakage point of the connected sewage pipeline for operation and maintenance at any position, avoiding the cutting of the pipeline position, being conducive to non-stop welding and operation and maintenance, improving the welding practicability of the sewage pipeline, solving the technical problems that the existing pipeline welding device cannot stably weld with the existing sewage operation and maintenance pipeline, cannot weld and clean the leakage point, and cannot realize the non-stop leakage repair of the operation and maintenance pipeline.
