Abstract
The utility model discloses a pipe line drawing tool. The tool comprises an arc line drawing plate and a baffle plate used for preventing the arc line drawing plate from moving. One line drawing edge of t he arc line drawing plate is vertically fixed with a spacing strip. The inner arc surface of the arc line drawing plate is provided with a slide device. The outer arc surface of the arc line drawing plate is provided with a handle. The tool is advantaged by being high line drawing flatness.
Description
Technical field
The utility model relates to petroleum pipeline maintenance aid field, particularly, relates to a kind of pipeline line tool.
Background technology
The pipe fitting that is applied to oil field all needs to possess higher intensity, resistance to pressure, corrosion-resistant, high temperature resistant type.In petroleum industry, need to lay longer pipeline and carry out transfer oil, because oil need to be laid on comparatively in rugged environment, when there is seepage in pipeline, the situation such as break is cannot repair welding time, the pipeline section that need more renew, in the process of changing, need carry out setting-out to caliber, so that cutting.Existing line tool, it adopts designation strip, designation strip is bundled on pipeline so that pipeline is carried out to setting-out, but because designation strip is when the binding, need is that designation strip is vertical with the central shaft of pipeline, just can make pipe cutting smooth.Because designation strip is soft, it is in the time of binding, and designation strip caliber easy and pipeline is offset, and makes pipe cutting dipped ring whole, affects welding quality.
Utility model content
Technical problem to be solved in the utility model is to provide the smooth pipeline line tool of a kind of setting-out.
The technical scheme in the invention for solving the above technical problem is:
Pipeline line tool, comprise arc scribing plate and for limiting the baffle plate of arc scribing plate shift position, on one setting-out limit of described arc scribing plate, be vertically fixed with positive stop strip, on the inner arc surface of described arc scribing plate, be provided with carriage, on the exterior arc surface of described arc scribing plate, be provided with handle.
As preferably, described carriage is ball.
Further, on the inner arc surface of described arc scribing plate, be provided with ball holddown groove, described ball is positioned at ball holddown groove, and the exposure of described ball is positioned at outside the inner arc surface of arc scribing plate.
Further, the height that described ball exceedes the inner arc surface of arc scribing plate mostly is 2 millimeters most.
Further, described ball holddown groove and ball have 2 at least.
Further, described ball holddown groove and ball have 3.
To sum up, the beneficial effects of the utility model are:
The utility model adopts the repeatedly mobile of arc scribing plate to indicate pipe cutting line, utilize positive stop strip to carry out preliminary judgement to the position relationship between arc scribing plate and pipeline center's axle, and utilize baffle plate to limit the shift position of arc scribing plate, in the time that the initial setting-out of arc scribing plate position is all consistent, the setting-out of caliber is smooth, and setting-out flatness of the present utility model is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of arc scribing plate in Fig. 1.
Mark and corresponding parts title in accompanying drawing: 1, arc scribing plate; 2, positive stop strip; 3, baffle plate; 4, handle; 5, ball; 6, ball holddown groove.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is done to detailed description further, but embodiment of the present utility model is not limited to this.
Embodiment 1:
A kind of pipeline line tool as depicted in figs. 1 and 2, comprise arc scribing plate 1 and for limiting the baffle plate 3 of arc scribing plate 1 shift position, on one setting-out limit of described arc scribing plate 1, be vertically fixed with positive stop strip 2, on the inner arc surface of described arc scribing plate 1, be provided with carriage, on the exterior arc surface of described arc scribing plate 1, be provided with handle 4.
In the utility model, utilize arc scribing plate 1 to carry out setting-out, arc scribing plate repeatedly moves repeatedly setting-out around circumference on pipeline, and in the time that the initial setting-out of arc scribing plate 1 all overlaps, the line of cut flatness of pipeline is high.In the time of preliminary setting-out, positive stop strip carries out preliminary judgement to the position relationship between arc scribing plate and pipeline center's axle, in the time of the central axes of positive stop strip and pipeline, can start setting-out, the length of positive stop strip is longer, and the position relationship between arc scribing plate and pipeline center's axle judges that the degree of accuracy is higher.Baffle plate is put on arc scribing plate 1 plate one setting-out limit, and the direction moving for limiting arc scribing plate 1, moves arc scribing plate 1 all the time along pipe circumference.Handle, for controlling the movement of arc scribing plate 1, is convenient to the operation of staff.Carriage is convenient to arc scribing plate 1 and is moved on pipeline, convenient operation.Adopt repeatedly setting-out to indicate the cut surface of pipeline, and initial setting-out position consistency show that the flatness of cut surface is high, the flatness of raising cutting.
Embodiment 2:
A kind of pipeline line tool as depicted in figs. 1 and 2, the present embodiment and embodiment 1 are roughly the same, and difference is that carriage is carried out to refinement, and carriage is ball 5.On the inner arc surface of described arc scribing plate 1, be provided with ball holddown groove 6, described ball 5 is positioned at ball holddown groove 6, and the exposure of described ball 5 is positioned at outside the inner arc surface of arc scribing plate 1.
In the present embodiment, adopt ball as carriage, ball slides, and can reduce the frictional force between pipeline, is convenient to mobile.And ball is simple in structure, be easy to realize.
Embodiment 3:
A kind of pipeline line tool as depicted in figs. 1 and 2, the present embodiment has done refinement to embodiment 2, and the height that ball 5 exceedes the inner arc surface of arc scribing plate 1 mostly is 2 millimeters most.The exposure of ball need be outside the inner arc surface of arc scribing plate 1, and ball rotates the movement that just can bring arc scribing plate 1, to reduce friction.Need be excessive at the height of the inner arc surface of arc scribing plate 1 when the exposure of ball, make the distance between arc scribing plate and pipeline too large, be unfavorable for the accuracy of setting-out.
Embodiment 4:
A kind of pipeline line tool as depicted in figs. 1 and 2, the present embodiment is on the basis of above-described embodiment, and described ball holddown groove 6 and ball 5 have 2 at least.Make arc scribing plate held stationary on pipeline, arc scribing plate two ends are consistent with the distance of pipeline, ensure the accuracy of setting-out.In the time only having a ball, arc scribing plate arc scribing plate two ends and pipeline outer wall distance on pipeline outer wall is inconsistent, is unfavorable for setting-out operation.
Embodiment 5:
A kind of pipeline line tool as depicted in figs. 1 and 2, the present embodiment on the basis of embodiment 4, preferred one group of data, described ball holddown groove 6 and ball 5 has 3.Can well ensure that by 3 groups of ball holddown grooves 6 and ball 5 arc scribing plate is consistent with the distance of pipeline, ensure the flatness of setting-out.
As mentioned above, can realize preferably the utility model.
