The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the present embodiment provides a large-sized pressure pipe welding heating coil device, which comprises a variable-frequency heating controller 1, a coil mechanism 2 and a temperature sensor 3. The coil mechanism 2 is used for wrapping the outer ring of the welding seam of the large-size pressure pipeline. The frequency conversion heating controller 1 is connected with a 380V industrial power supply through a power supply wiring and is connected with the coil mechanism 2, and the frequency of alternating current in the coil mechanism 2 can be adjusted according to needs by the frequency conversion heating controller 1. The temperature sensor 3 is arranged on the coil machine and used for collecting the surface temperature of the heated large-size pressure pipeline and transmitting a temperature signal back to the variable-frequency heating controller 1 to adjust the frequency of the output alternating current. The eddy current induced in the large-size pressure pipeline can heat the pipeline welding seam.
As shown in fig. 2, the coil mechanism 2 specifically includes a coil movable arm 21, a load-bearing cable 22, a control cable 23, an energizing coil 24, and a fixing buckle 25. Coil movable arm 21 is including forming annular structure's first connecting block 211, second connecting block 212 and third connecting block 213, first connecting block 211 and the both ends of articulated third connecting block 213 of second connecting block 212 distribution, through fixed buckle 25 swing joint between first connecting block 211 and the second connecting block 212. The upper end of the third connecting block 213 is connected with a load-bearing steel cable 22, and the upper ends of the first connecting block 211 and the second connecting block 212 are connected with a control steel cable 23. The load-bearing cables 22 and the control cables 23 are pulled and moved by an external device. Therefore, when facing a large-size pressure pipeline, the coil movable arm 21 consisting of the three connecting blocks can be unfolded and sleeved outside the large-size pressure pipeline and then folded by the control steel cable 23 to form the enclosure of the large-size pressure pipeline. First connecting block 211, second connecting block 212 and third connecting block 213 all include two support curb plates 41 that set up relatively, and it has wire support 42 to distribute between the support curb plate 41, and circular telegram coil 24 fixes on wire support 42. The two ends of the wire support 42 are connected with the support side plate 41 by support rivets. The temperature sensors 3 are distributed and fixed on the wire bracket 42. Electric coil 24 presents the C type and distributes on the wire support 42 of first connecting block 211, second connecting block 212 and third connecting block 213 to electric coil 24 tip on first connecting block 211 and second connecting block 212 is equipped with wire clamp 26, connects the back through fixed buckle 25 when first connecting block 211 and second connecting block 212, and electric coil 24 also passes through wire clamp 26 intercommunication on two connecting blocks, forms complete O type return circuit.

When the heating coil is used, a power supply wiring is connected with the variable-frequency heating controller 1, the variable-frequency heating controller 1 is turned on, and ultrahigh-frequency alternating current flows through the heating coil to generate a high-frequency alternating magnetic field. Induced current (eddy current) is generated in a large-size pressure pipeline (generally from a carbon steel pipeline to a stainless steel pipeline) under the action of a high-frequency alternating magnetic field, and the large-size pressure pipeline is rapidly heated under the action of the induced current. The temperature sensors 3 distributed in the coil mechanism 2 can monitor the surface temperature of the large-size pressure pipeline, and transmit signals to the variable-frequency heating controller 1 through the temperature sensors 3 to adjust the frequency of output current.
