Description
Technical field
The present invention relates to petroleum gas transportation technology and apparatus field, relate in particular to a kind of oblique dip stick of cutting of oil transportation gas steel pipe.
Background technology
Long oil and gas pipeline is to be formed by connecting by a large amount of pipeline steel tubes, needs for site welding, pipe end need be processed, it is an important index of pipe end processing and steel pipe appearance and dimension check that pipe end is cut bevel very little, it is very little too big that pipe end is cut bevel, excesssive gap during the pipeline field joint causes the welding difficulty, influences the welding quality and the safety of pipeline.Therefore, APISPEC 5L " pipeline steel tube standard ", GB/T9711 series " industrial gas oil conveying steel pipe delivery technical conditions " and each pipework technical conditions tiltedly all have strict regulation to cutting of steel pipe, cut oblique definition as shown in Figure 1 about pipe end in various standards and the technical specification book, wherein S is for cutting tiltedly.
Present domestic tube mill generally adopts simple and easy try square, plumb bob and clearance gauge to come measuring tube end-grain cutting bevel very little, as shown in Figure 2, at first steel pipe is placed on the rotation platform, use then clearance gauge measure between steel pipe and try square or the plumb bob apart from S, measuring method is as shown in Figure 2.
Current domestic try square method and the end-grain cutting of generally adopting of plumb bob method measuring tube is oblique, and owing to existing unreasonable structure, precision to cause measurement result inaccurate inadequately, and measurement is difficult for controlling.There are the following problems respectively for two kinds of measuring methods:
1, plumb bob method: when the plumb bob method is measured, sash weight is unsettled, utilizes clearance gauge to measure the distance at plumb line and pipe end edge, because plumb line is fixing difficult, swing easily, even if plumb line is fixing, when using clearance gauge to measure, for making measurement result accurate, clearance gauge must be tried one's best near vertical line, clearance gauge touching plumb line must cause the plumb line swing, makes to measure and controls difficulty, and the result is inaccurate.
2, try square method: because some pipe ends surface and platform depth of parallelism difference to some extent, especially need the spiral submerged arc welded steel pipe of pipe end hole enlargement, can form slightly " loudspeaker " shape at pipe end, as shown in Figure 3, caused that try square records to cut bevel cun error relatively large, and " tubaeform " is serious more, diameter of steel tube is big more, the measuring error that causes is big more, as shown in Figure 4, S2 is a measured value, and S1 is an actual value, S2 is greater than S1, and increases along with the increase of caliber.
In addition, use the clearance gauge measurement to cut and need select the thickness chi repeatedly when oblique, the value of each thickness chi of addition is again operated more loaded down with trivial details afterwards.
Summary of the invention
The objective of the invention is to design a kind of oblique dip stick of cutting of novel oil transportation gas steel pipe, overcome above-mentioned shortcoming of the prior art, address the above problem.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of oil transportation gas steel pipe cut oblique dip stick, comprise right angle main scale, milscale, slide rail and level(l)ing device, described right angle main scale comprises surveyor's staff and miter square, described miter square is provided with described slide rail, described surveyor's staff is provided with described level(l)ing device, described milscale slides on described slide rail, and the direction of measurement of described milscale is perpendicular to the glide direction of described milscale on described slide rail, and the surface level that described level(l)ing device is regulated is vertical with the glide direction of described milscale on described slide rail.
Also be provided with level meter on the described surveyor's staff.
Described level(l)ing device is that two of being provided with about on the described surveyor's staff regulate bolts.
Described adjusting bolt is the magnetic material bolt.
Also comprise the fastener that is used for fixing relative position between described right angle main scale and the described milscale.
Described fastener is a fastening bolt.
Described milscale is a digimatic micrometer.
Level(l)ing device in the utility model, the levelness that is used to regulate the right angle main scale, its material can be magnetic material in addition, can make during use to survey on the chi absorption steel pipe, guarantees to survey chi stability, is convenient to measure; Level meter in the utility model, the reveal competence state is embedded in the surveyor's staff of main scale; Fastener in the utility model is used for fixing the relative position of milscale and main scale; Milscale locking device in the utility model is used to lock milscale and rotates, and is convenient to reading.
Beneficial effect of the present invention is as follows:
(1) to cut oblique dip stick measuring accuracy very high for the utility model steel pipe, because it uses milscale to replace clearance gauge when measuring, measuring accuracy improves greatly.
(2) the utility model steel pipe is cut oblique measurement level meter and level(l)ing device is installed, can regulate the levelness of dip stick and platform, even steel pipe is measured the depth of parallelism relatively poor (hole enlargement causes as pipe end slight " loudspeaker ") of face and platform, also can be by regulating levelness, accurately record it and truly cut bevel cun.
(3) the utility model steel pipe is cut oblique dip stick and is had slide rail, and milscale can slippage up and down on main scale, and suitable diverse location is cut tiltedly the measurement of (going up tiltedly or declivity), and it is oblique also can to measure cutting of various caliber steel pipes.
(4) operation is succinctly not loaded down with trivial details, and convenient reading is easy to control.
