Embodiment 1

[0020] Such as figure 1 The shown marking device for oil pipeline processing includes a left bracket and a right bracket. Both the left bracket and the right bracket include an arc-shaped mounting seat 1 at the upper end, a support column 4 at the middle end, and a fixed disc 6 at the lower end. Support and right support are connected by scale rod 8, and described scale rod 8 two ends are respectively connected with the support column 4 of left support and right support horizontally, on scale rod 8, be covered with two vertically arranged marking rulers 7, described The two scales 7 can slide axially along the scale rod 8 .

[0021] When this embodiment is used, the device is placed in a suitable position in advance, the oil pipeline is placed flat on the arc mounting seats 1 of the left bracket and the right bracket, the length scale is engraved on the scale rod 8, the position of the pipeline is adjusted, and then according to The size to be marked moves the marking ruler ...

Embodiment 2

[0023] see figure 2 with image 3 , the present embodiment optimizes the structure of the scale on the basis of Embodiment 1, specifically: the scale 7 includes a sliding sleeve 71 and a vertical rod 72 connected to the upper end of the sliding sleeve 71, and the upper end of the vertical rod 72 is provided with a Spring mounting hole 721, a compression spring 73 is set in the spring mounting hole 721, a marking pen 74 is also installed in the spring mounting hole 721, the lower end of the marking pen 74 is located at the upper end of the compression spring 73, and a refill mounting hole is set at the upper end of the marking pen 74 741.

[0024] The sliding sleeve 71 of this embodiment fits on the scale rod 8 and can move axially along the scale rod 8. The marking pen 74 compresses the compression spring 73 and is installed in the spring mounting hole 721. The pen core mounting hole 741 can be placed with different colors To mark the refill, when marking, the upper end of...

Embodiment 3

[0027] In this embodiment, the following structure is added on the basis of embodiment 1 or embodiment 2: arc-shaped rubber pads 2 are provided on the inner arc surfaces of the arc-shaped mounting seats 1 of the left bracket and the right bracket.

[0028] The rubber pad 2 of this embodiment can reduce the mutual friction between the oil pipeline and the arc-shaped mounting seat 1, reduce wear, and at the same time facilitate the rotation of the oil pipeline, excellently protect the outer wall of the oil pipeline, and improve safety.

Abstract

The invention discloses a labeling device used for machining a petroleum pipeline. The labeling device comprises a left support and a right support, wherein the left support and the right support respectively comprise an arc-shaped mounting base (1) at the upper end, a supporting column (4) at the middle end, and a fixing disk (6) at the lower end, the left support and the right support are connected through a scaleplate rod (8), the two ends of the scaleplate rod (8) are horizontally connected with the supporting column (4) of the left support and the supporting column (4) of the right support respectively, the scaleplate rod (8) is sleeved with two vertically arranged labeling rulers (7), and the two labeling rulers (7) can slide in the axial direction of the scaleplate rod (8). With the device, the cutting size and the hole size of the petroleum pipeline can be accurately labeled, and therefore the subsequent machining accuracy of the pipeline is improved, machining errors are reduced, and machining accuracy is improved; meanwhile, the device can be used for labeling the size of two holes having the interval requirement, practicality is high, the acting force between a labeling pen and the petroleum pipeline is small, the surface of the petroleum pipeline and the labeling pen can be protected well, and the protecting performance is good.

Description

technical field [0001] The invention relates to an auxiliary processing device for oil pipelines, in particular to a marking device for processing oil pipelines. Background technique [0002] Due to the heavy weight, large diameter and length of the oil pipeline, the processing size is generally marked before processing is required. Most of the current oil pipeline markings are manually measured and marked by the processor using a tape measure. The marked processing position generally has a relatively large size deviation. Large, for some oil pipelines that require high precision in size, it is very easy to make processing errors due to measurement errors, which wastes processing materials, increases the workload of workers, and is not conducive to accurate processing of pipelines. [0003] The current marking tools generally have only one marking ruler, which can only be used for general size cutting position marking or single hole position marking. However, if two holes wi...
