Technical Field
[0001] The utility model belongs to the technical field of welding, in particular to a PVC power pipe welding device. Background Art
[0002] PVC pipe is a kind of pipe with polyvinyl chloride as the main material. It has the characteristics of strong corrosion resistance, easy bonding and low price. It is widely used in the field of water and electricity transmission. During the installation of PVC power pipe, the installer often needs to connect two PVC power pipes together to extend the transmission distance and change the transmission direction.
[0003] Currently, before butt welding of pipes, the opposite sides of the two pipes need to be extended to the clamps by about 20 cm to meet the needs of subsequent welding operations. Since the pipes are installed separately on the clamps on both sides, it is difficult to keep the distance between the two pipes and the outside of the clamps consistent after installation, resulting in the need to adjust the pipes multiple times, which is time-consuming and labor-intensive, and also affects the subsequent welding quality.
[0004] In view of this, a PVC power pipe welding device is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a PVC power pipe welding device in order to solve the above-mentioned problems.
[0006] The technical solution adopted by the utility model is as follows: a PVC power pipe welding device, comprising a base plate, a screw rack is installed on the upper end of the base plate along the length direction, a bidirectional screw is rotatably installed on the screw rack, and corresponding screw nuts are respectively provided at opposite threads on both sides of the bidirectional screw, and a fixing component for fixing the pipeline is installed on the upper end of the screw nut, the fixing component comprises a fixing seat and a plurality of fixing heads that can move up and down and are arranged above the fixing seat, and a V-shaped groove for placing pipelines of different sizes is opened above the fixing seat; a limiting component for limiting the position of the power pipe is provided between the two fixing components, the limiting component comprises a limiting plate that is larger than the size of the power pipe, and the bottom of the limiting plate can be detachably installed above the center of the screw rack.
[0007] In a preferred embodiment, a level is embedded in the upper end surface of the base plate.
[0008] In a preferred embodiment, guide rails are installed at both ends of the screw rod frame along the length direction, and guide blocks for guiding and sliding on the guide rails are provided on both sides of the screw rod nut.

[0011] In a preferred embodiment, a second fixing screw is installed at the upper end of the fixing head, and the fixing assembly also includes an arc-shaped fixing frame. The second fixing screw is threadedly installed at the center of the fixing frame, and the heads of the fixing screw and the second fixing screw are both integrally provided with a turning handle.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
