Magnetic head framework for heating pipe

The utility model discloses a magnetic head skeleton used for a heating pipe, comprising a bearing frame (1) and magnetic head frames (2), the bearing frame (1) is annular and is installed on the heating pipe along the circumferential direction of the heating pipe, the number of the magnetic head frames (2) is at least two, the magnetic head frames (2) are arranged on the bearing frame (1) in a pairwise opposite mode, preferably, the number of the magnetic head frames (2) is four, and two pairs of magnetic head frames are formed. Every two magnetic head frames which are oppositely arranged in pairs form a pair, the two pairs of magnetic head frames are perpendicular to each other, and the bearing frame (1) and the magnetic head frames (2) are integrally formed into a whole. According to the utility model, high fitting degree of the magnetic heads and the wall of the heating pipe can be ensured, the magnetic heads and the wall of the heating pipe can be kept vertical, and the angle between the magnetic heads c
