Description

Technical Field

[0001] The utility model relates to the technical field of municipal pipelines, in particular to a municipal pipeline welding frame. Background Art

[0002] High-density polyethylene pipes are widely used in municipal pipe network projects, and are generally connected by hot-melt welding. When welding, a special welding frame is required to align the pipes, and the welding frame is manually controlled during the hot-melt process to apply pressure to the pipes so that the ends of the pipes fuse together. In the existing pipe welding frame structure, construction workers need to manually turn the crank to drive one pipe to move toward the other. During the fusion process of the two pipe ends, construction workers need to manually maintain pressure to promote the fusion and docking of the pipes. However, inexperienced construction workers find it difficult to control the strength of the pressure applied, which can easily lead to poor quality of pipe welding.

[0003] The existing authorized patent number is CN 220429337 U, which is a municipal pipeline welding frame. The frame includes a frame body, a fixed pipe clamp and a sliding pipe clamp are provided on the frame body, and a driving mechanism for driving the sliding pipe clamp to move is also provided on the frame body. An abutment portion is provided on the sliding pipe clamp, and a push rod is slidably provided at one end of the frame body, one end of the push rod abuts against the abutment portion, a limiting portion is provided on the push rod, and a thrust spring is sleeved on the push rod, and both ends of the thrust spring abut against the limiting portion and the frame body respectively.

[0004] The above equipment has a reasonable structure. A push rod driven by a thrust spring is arranged on the frame. When the pipe ends are welded and fused, the spring is used to provide a stable and accurate pushing pressure, thereby ensuring the fusion quality of the pipe ends. The equipment has a simple structure and is easy to operate. However, with the existing municipal pipe welding frame, the municipal pipes have different radii during the welding process, and it is impossible to quickly and conveniently clamp the municipal pipes of different radii during adjustment.

[0029] The whole municipal pipeline welding frame is supported by the support plate 1 , the collecting tank 3 can be rotated by the rotating shaft 2 , and the fixing ring 6 can be rotated on the inner wall of the fixing block 4 by the annular groove 5 .

[0031] Through the adaptive matching between the sliding block 10 and the thread groove 9, the thread groove 9 can drive the sliding block 10 to slide outward when rotating, so that the clamping block 11 spreads outward.

[0032] The inner wall of the fixed block 4 is fixedly connected with a motor 12 , the output end of the motor 12 is fixedly connected with a gear 13 , and the outer wall of one side of the connecting disk 8 is fixedly connected with a toothed disk 14 , and the toothed disk 14 is meshedly connected with the gear 13 .

[0033] Through the meshing connection between the toothed disc 14 and the gear 13 , the output end of the motor 12 drives the gear 13 to rotate, which can drive the toothed disc 14 to rotate, and further drive the connecting disc 8 to rotate.

[0034] A support rod 15 is fixedly connected to the inner wall of the rotating shaft 2 , a support block 16 is fixedly connected to the outer wall of the support rod 15 , and a placement plate 17 is fixedly connected to the top of the support block 16 .

[0035] The pressure brought by the pipeline can be dispersed by the support rod 15. While one end of the pipeline to be welded is fixed, the other end of the pipeline is supported by the placement plate 17, so that the pipeline remains stable during the welding process.

[0036] The outer wall of the support plate 1 is fixedly connected with a sliding groove 18, and the support rod 15 is slidably connected to the inner wall of the sliding groove 18.

After fixing one end of the pipeline by the clamping block 11, the other end of the pipeline can be placed inside the placement plate 17, which can be clamped. While block 11 shares the gravity, it can also make the pipeline more stable during welding and make welding more convenient for the staff.

When not in use, the rotating shaft 2 can be rotated to flip the collection tank 3 to the top. The bottom of the collection tank 3 can block the dust falling from the top. By pulling the support plate 1 horizontally, the telescopic slot 19 inside the collection tank 3 is pulled out, and the telescopic slot 19 at the bottom of the support plate 1 is pulled out synchronously, so that the overall structure of the pipeline welding rack becomes longer, which can adapt to municipal pipelines of different lengths and has extremely high adaptability.
