Problems solved by technology

[0003] However, the existing conventional electromagnetic induction heaters are mainly used to heat small workpieces. The induction heating coil is usually closed or fixed, and the volume of the induction heating workpiece is limited at the beginning of the design. For the welding of the jacket Seams, some with a diameter of 4.2m, cannot use fixed or closed induction coils when heating
The current on-site heating of large jacket welds is mainly through heat conduction instead of induction heating. However, the heating efficiency of heat conduction heating is low, the heating time is long, the heating temperature is difficult to meet the requirements, and it is not easy to control

Embodiment Construction

[0038] Such as figure 1As shown, the flexible assembled heating inductor in a preferred embodiment of the present invention is especially suitable for inductively heating the weld seam positions of large workpieces such as jacket platforms in offshore oil platforms, and it is understandable that it does not Heating of small workpieces is ruled out. The flexibly assembled heating sensor includes several flexible cables 2, and the number of flexible cables 2 in this embodiment may be but not limited to ten. Both ends of each flexible cable 2 are respectively connected with a first joint 3 and a second joint 4, and the first joint 3 and the second joint are matched. Specifically, the two ends of each flexible cable 2 are respectively mechanically and electrically connected to the first connector 3 and the second connector 4; They are all matched and connected with the second joint 4 on the previous flexible cable 2, and connected in sequence to form an induction coil 200, that ...

Abstract

The invention discloses a flexible fabricated induction heater which comprises an induction coil formed by several flexible cables in a tandem connection mode. Two ends of each flexible cable are both connected with a first connector and a second connector adaptive to the first connector respectively, mechanically and electrically. The first connector of each later flexible cable is connected with the second connector of a former flexible cable connected with the later flexible cable mechanically, electrically and separably. The flexible fabricated induction heater avoids excessive winding of the cables, and is easy and rapid to install, and suitable for heating large and small workpieces.

Description

technical field [0001] The invention relates to an induction heater, in particular to a flexible assembled induction heater. Background technique [0002] In the welding of large workpieces, such as jacket welding, welding residual stress is often generated during the welding process due to objective factors, and the method of heating the welding seam can eliminate welding residual stress. The methods of heating the workpiece include heat conduction heating and electromagnetic induction heating. At present, the heating method used for large workpieces such as jacket welds is mainly through heat conduction heating. However, heat conduction heating has disadvantages such as low heating efficiency, long heating time, difficult to meet the requirements of heating temperature, and inconvenient control. Induction heating is generally realized by an electromagnetic induction heater. The principle of using an electromagnetic induction heater to heat a workpiece is: the electromagn...
