Description

Technical Field

[0001] The utility model belongs to the technical field of pipe melting, in particular to an electromagnetic melting device for plastic-lined pipes. Background Art

[0002] The plastic-lined pipe is based on ordinary carbonate steel pipe and is formed by cold processing. The characteristics of the plastic-lined pipe are also very obvious. It has anti-corrosion function and is not easy to generate microorganisms. It is widely used in industry, ionization, metallurgy and food fields. After installation, the plastic-lined pipe needs to be connected at the butt joint of the two pipes. The existing connection prevents the electromagnetic melting device from heating the pipe interface once and then docking after heating. Although the melting docking of the pipe can be achieved, the stability of the two pipes needs to be ensured during the docking. Manual stabilization will increase the labor intensity of the workers and the docking effect is not good.

[0003] For example, the Chinese utility model application number is 202020712982.8, which describes a pipe hot-melt butt-jointing device, comprising a heat shield and a heating device, wherein the heat shield is sleeved with the heating device, and the butt-jointing device further comprises an intelligent control device and a plurality of retractable temperature sensing devices, wherein the heating device and the temperature sensing device are both communicatively connected to the intelligent control device. Although this patent can achieve the fusion butt-jointing of pipes, it is necessary to ensure the stability of the two pipes during the butt-jointing process. Manual stabilization increases the workload of the workers, and the butt-jointing effect is poor. Utility Model Content

[0011] Preferably, a stepping motor for providing adjustment power to the second screw rod is installed on the side of the mounting frame.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:
