Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as Figure 1~2 As shown, the present invention provides a measuring device for the center offset of fish-belly submerged arc welds in the middle sill of a flat car. The board 1 and the detection board 3 are located at both ends of the horizontal board 2, forming a knife handle structure. The lower end of the inner side of the vertical plate 1 is provided with a boss 4 in the shape of an isosceles trapezoid. The detection board 3 is integrally formed by connecting the horizontal board 5, the inclined board 6, the vertical board 7, the scale board 8 and the straight board 9 end to end; the end of the horizontal board 5 connected with the straight board 9 is connected with the horizontal board 2; Surround a draw-in groove 10 with the straight plate 9;
[0022] In a preferred embodiment, the distance between the boss 4 and the straight plat...
