Embodiment 1

[0019] Such as Figure 1 to Figure 3 The shown oil pipeline cutting and marking tool includes an arc-shaped marking board, an arc-shaped groove is arranged on the inner arc surface of the marking board, and an arc-shaped fixing plate 6 is arranged in the groove , the fixed plate 6 is fixed with a layer of sponge 7, the fixed plate 6 is located between the marking plate 1 and the sponge 7, the button 5 is fixed on the described fixing plate 6, the marking plate 1 There is a hole, the button 5 passes through the hole, the four sides of the sponge 7 are respectively parallel to the four sides of the marking board 1, the thickness of the fixing plate 6 and the sponge 7 is less than the thickness of the groove, A handle 4 is provided on the outer arc surface of the marking board 1 .

[0020] In this embodiment, the pipe diameters of the pipes are compared using an arc-shaped marking board, and the pipes are drawn using the sponge in the arc-shaped groove on the inner circular arc ...

Embodiment 2

[0022] Such as Figure 1 to Figure 3 Shown is a tool for cutting and marking oil pipelines. In this embodiment, on the basis of the above embodiments, a ruler 2 is vertically fixed on one side of the marking board 1 .

[0023] The length of described ruler 2 is at least 20 centimetres.

[0024] Ruler 2 makes a preliminary judgment on the positional relationship between the arc-shaped marking plate and the central axis of the pipe. When the ruler 2 is parallel to the central axis of the pipe, the line can be drawn. The higher the accuracy of determining the positional relationship between the plate and the central axis of the pipe, that is, its length is at least 20 cm.

Embodiment 3

[0026] Such as Figure 1 to Figure 3 The oil pipeline cutting and marking tool shown in this embodiment, on the basis of the above embodiments, further includes a baffle plate 3 for limiting the moving direction of the marking board 1 . The baffle plate 3 is used to limit the moving direction of the marking board 1, that is to make the marking board 1 move along the diameter of the pipeline so that the marking line is always along the diameter of the pipeline.

Abstract

The invention discloses a petroleum pipeline cutting marking tool. The petroleum pipeline cutting marking tool comprises an arc marking-off plate. An arc groove is formed in the inner arc face of the marking-off plate. An arc fixing plate is arranged in the groove. A layer of sponge is fixed to the fixing plate. The fixing plate is located between the marking-off plate and the sponge. A button is fixed to the fixing plate. A hole is formed in the marking-off plate. The button penetrates through the hole. The four edges of the sponge are parallel to the four edges of the marking-off plate. The thickness of the fixing plate and the thickness of the sponge are smaller than that of the groove. A handle is arranged on the outer arc face of the marking-off plate. Operation is simple and marking-off is flat.

Description

technical field [0001] The invention relates to the field of auxiliary tools for oil pipeline maintenance, in particular to an oil pipeline cutting and marking tool. Background technique [0002] Pipe fittings used in the petroleum field need to have high strength, pressure resistance, corrosion resistance, and high temperature resistance. In the oil industry, it is necessary to lay long pipelines to transport oil. Since oil needs to be laid in a relatively harsh environment, when the pipeline leaks, ruptures, etc. and cannot be repaired, it is necessary to replace the new pipe section. During the replacement process In , you need to draw a line on the pipe diameter to facilitate cutting. The existing line drawing tools use marking strips, which are bound to the pipe, and then use the line drawing tool to draw lines according to the marking strips. If it is not vertical, the pipe will be cut unevenly. Contents of the invention [0003] The technical problem to be solved...
