Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention. Thus, the following detailed description of the embodiments of the present invention, presented in the accompanying drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in figure 1, a pipeline ovality detects and cuts neat mouthful drawing instrument, including cross support 1, first scale 3 is all connected to each stabilizer blade 2 of cross support 1, and the tip of first scale 3 is provided with second scale 4 perpendicularly, all has the scale on each stabilizer blade 2 of cross support. The first scale is a circular tube and is sleeved on the support leg 2 of the cross-shaped support, the first scale is connected with the support leg of the cross-shaped support through a locking bolt 5, and the inner side of the end part of the second scale is provided with a needle-shaped object.

The working process when the pipeline ovality is detected is as follows: as shown in fig. 2, firstly, a tool is placed at the end of the pipeline 6 to be measured, the four first graduated scales are respectively adjusted, the four second graduated scales are all tightly attached to the outer wall of the pipeline, and the locking bolts on the first graduated scales are locked; the sizes of the support legs in four mutually perpendicular directions of the cross-shaped support and the first graduated scale are recorded, the readings of the four support legs and the readings of the four first graduated scales are recorded, and the ovality of the pipeline can be calculated. Recording the sum of the reading of one support leg and the reading of the first scale connected with the support leg, recording the sum of the reading of the other support leg in the same horizontal direction and the reading of the first scale connected with the support leg, adding the two sums to obtain the diameter of the pipeline, obtaining the diameter of the pipeline in the same direction perpendicular to the diameter of the other direction, comparing the two measured diameters, and if the two measured diameters are equal, indicating that the ovality of the pipeline reaches the standard; if the ovality is not equal or exceeds the standard requirement, the ovality of the pipeline is not up to the standard, the replacement can be directly required, unnecessary work is avoided, and human resources are saved.

The working process when the pipeline is cut and the sample is drawn is as follows: firstly, placing a tool at the end of a pipeline 6 to be measured, respectively adjusting four first graduated scales to ensure that four second graduated scales are tightly attached to the outer wall of the pipeline, and locking each locking bolt on the first graduated scales; and selecting the same numerical value scale on the second scale, such as the numerical value of 5.0, drawing points, connecting four-point connecting lines by using a chalk line or a steel plate ruler, namely forming a pipeline circumference line, wherein the line is vertical to the pipeline axis, and cutting according to the line to cut a neat mouth vertical to the pipeline axis. As shown in fig. 2, if the end of the pipeline to be measured is uneven, the highest point of the end of the pipeline to be measured should be close to the first graduated scale, and it is ensured that the four second graduated scales are all tightly attached to the outer wall of the pipeline.

The needle-shaped object is arranged on the inner side of the end of the second scale, the pipeline to be measured is fixed, the pipeline ovality detection and the cut sample drawing tool with the same opening are rotated, the needle-shaped object can be marked on the circumference of the pipeline, the marked circumference is perpendicular to the axis of the pipeline, and the sample drawing tool with the same opening perpendicular to the axis of the pipeline can be cut according to the cutting of the line.

The utility model has simple structure, convenient operation and low cost; the pipeline cutting device can be suitable for pipelines with different diameters, can finish the detection of ovality on the pipeline, and can also perform pipeline cutting and sample aligning. If the measured pipeline exceeds the standard requirement, the ovality of the pipeline is not up to the standard, and the pipeline can be directly required to be changed, so that unnecessary work is avoided, and the manpower resource is saved.

In the present disclosure, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact between the first and second features, or may comprise contact between the first and second features not directly. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature.
