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...

Abstract

The invention relates to a device and method for measuring the center bias of a fish-bellied submerged arc weld of a center sill of a flatcar. The device comprises a vertical plate I, a horizontal plate and a detection plate which are integrally formed, wherein the vertical plate and the detection plate are positioned at the two ends of the horizontal plate to form a knife handle shape convenient to held; an isosceles trapezoidal boss is arranged at the lower end of the inner side of the vertical plate; the detection plate comprises a transverse plate, an oblique plate, a vertical plate II, a scale plate and a straight plate which are connected end to end and integrally formed; the horizontal plate is connected to one end, connected with the straight plate, of the transverse plate; the vertical plate I, the horizontal plate and the straight plate define a clamping groove; the scale plate is horizontally arranged, an isosceles trapezoidal groove is formed in the scale plate, and millimeter graduation is marked on the horizontal edge of the upper end of the groove to serve as a scale. The device can be widely applied to measurement of the center bias of the fish-bellied submerged arc weld of the center sill of the flatcar.

Description

technical field [0001] The invention relates to a device and method for measuring the center offset of a submerged arc weld, in particular to a device and a method for measuring the center offset of a fish-belly submerged arc weld in the middle beam of a flat car. Background technique [0002] The special flat car for containers is a special vehicle for railway shipment of containers, and the shared flat car is a dual-purpose vehicle for loading large cargo or containers. The two models occupy a dominant position in China's railway transportation and are often opened in the form of special trains. Domestic railway freight cars The production plants are basically qualified for mass production. [0003] The flat car structure, that is, the car body structure only has an underframe, without end walls and side walls, and all loads are borne by the underframe. The bottom frame is mainly welded by the center beam, side beams, end beams and various transverse beams. The center bea...
