Description
Technical field
The present invention relates to standpipe cutting, more particularly to a kind of technics of slot of standpipe.
Background technology
Middle-size and small-size jacket is at sea completed after piling, suspension centre, ring flat-plate cutting and related installation procedure, need to be to jacket
Standpipe is (i.e.：Main pipe) it is attached with piling bar.At present, standpipe has two kinds with the mode that piling bar is attached：One is：By standpipe
Cut into crown-shaped mode.Two are：U-type groove is cut on standpipe, and by the way of arc-shaped gaps version is connected with piling bar.Due to
When cutting U-lag on standpipe, completed using hand cut mode, therefore, be primarily present following shortcoming：
1. because U-lag is in the thick section of standpipe, tube wall is thicker (50 to 120 millimeters), therefore to operating personnel
Selectivity it is higher.
2. cut due to protecting balance mode using itself standpipe, therefore, its less stable, and by being cut
The U-lag cut is rough-shape, causes that its operation difficulty is larger, and production efficiency is relatively low.
3. because cut quality is relatively low, the later stage also needs to carry out repair welding, polishing and related check to ensure quality, therefore, raw
Produce cost higher.
The content of the invention
It is a primary object of the present invention to overcome the disadvantages mentioned above that prior art is present, and provide a kind of improved standpipe
Technics of slot, its method is simple, easy to use, and operation difficulty and the work for not only significantly reducing cutting vertical pipe U-lag are strong
Degree, improves standpipe U-lag cut quality；Moreover, having saved the engineering time, production cost is greatly reduced, life is improved
Produce efficiency.
The purpose of the present invention is realized by following technical scheme：
A kind of technics of slot of standpipe, it is characterised in that：Using following cutting step：
The first step：Make the groover and U-lag marking-off plate of subsidiary conduit cutting machine；
Second step：The center of U-lag is calibrated above riser end, then, by the center of U-lag marking-off plate
It is placed in the center calibration position of U-lag, and is rule within one week along U-lag marking-off plate；
3rd step：Groover is placed on standpipe appropriate location, then pipe cutter is positioned on groover, according to
Sequence completes cutting preparation；
4th step：Above riser end, and cut along the U-lag perpendicular cuts of U-lag marking-off plate,
During semicircle intersection to be cut to U-lag, pipe cutter is adjusted upward；Then, by groover together with pipe cutting
Machine is lifted up in the lump, and after groover and standpipe are contactless, cut object is adjusted to another perpendicular cuts face of U-lag
Position, repetition is from top to bottom cut to the semicircle intersection position of U-lag along perpendicular cuts；Then, by cut object
It is moved to another U-lag cutting position；Repeat above-mentioned cutting mode and completed until the U-shaped facade of the whole circle of standpipe is cut；
5th step：Cut along the both sides U-lag knuckle of riser end U-lag line of cut, then along below U-lag
Semicircle line of cut cut；Now, the iron block of cutting U-lag formation is cut with standpipe, and iron block is taken out；Repeat above
Cutting mode, until the U-lag knuckle of the whole circle of standpipe, the cutting of U-lag semicircle are completed；
6th step：The first step is repeated to the 5th step, continues to cut the standpipe U-lag of adjacent position：Until by bed rearrangement conduit
The standpipe U-lag cutting of frame is completed.
The groover includes：One surface plate, two hooks on surface plate.
The surface plate is rectangle.
Beneficial effects of the present invention：The present invention is due to using above-mentioned technical proposal, and its method is simple, easy to use, not only
The operation difficulty and labor intensity of cutting vertical pipe U-lag are significantly reduced, standpipe U-lag cut quality is improved；Moreover, section
About the engineering time, production cost is greatly reduced, improve production efficiency.

Major Symbol explanation in figure：
Embodiment
As shown in Fig. 1-Fig. 4, the present invention uses following cutting step：
The first step：Make the groover 2 and U-lag marking-off plate 1 of subsidiary conduit cutting machine 4；
As shown in Fig. 2 groover 2 includes：One surface plate, two on surface plate are arranged on using welding connecting mode
Hook 3, wherein, 70-100 millimeters are advisable above 3 anomaly panels of hook, and two hooks are down, are uniformly distributed.
Above-mentioned surface plate is that rectangle (thickness is 6-10 millimeters and is advisable), hook 3 are iron structure.
The length that above-mentioned hook 3 is connected with surface plate is consistent with cutting the thickness spacing of leading tube wall, with convenient
Cutter device is suspended to the steady of tube wall, beneficial to operation.
The width of above-mentioned surface plate, should be slightly bigger than the width (the magnet wheel for being more than pipe cutter) of pipe cutter, with
It is easy to operation；The length of surface plate should be greater than the facade length of cut U-type groove, to reach that pipe cutter adsorbs cutter device
Surface plate cutting process in, meet cutting length.
U-lag marking-off plate 1 is：Paper products, plastic products or metallic article (sheet metal), according to the size of U-type groove
Specification makes template by hand.
Second step：First use metering outfit (the present embodiment：Using disk chi or tape measure), according to the U-lag position that drawing is set
Put, the center of U-lag is calibrated above riser end, then, the center of U-lag marking-off plate 1 is placed in U-lag
In the calibration position of center, and rule within 1 one weeks along U-lag marking-off plate with paintbrush；
Sander or other manner are first used before line, the painting layer of scribing position is removed, now, original line has disappeared
Lose, repeat and rule using template；
3rd step：Groover 2 is placed on standpipe appropriate location, and checks pipe cutter 4, band to be confirmed is magnetic
After runner is bright and clean, then pipe cutter is put 4 be placed on groover 2, sequentially complete cutting angle, gas band, power supply and connect
Deng cutting preparation；
4th step：Above riser end, and cut along the U-lag perpendicular cuts of U-lag marking-off plate 1
Cut, during semicircle intersection to be cut to U-lag, pipe cutter 4 is adjusted upward；Then, both hands by groover 2 together with
Pipe cutter 4 is lifted up in the lump, and after the hook 3 of groover 2 is contactless with standpipe, cut object is adjusted to U
The position in another perpendicular cuts face of shape groove, repetition is from top to bottom cut to the semicircle intersection position of U-lag along perpendicular cuts；
Then, cut object is moved to another U-lag cutting position；Cutting mode above is repeated, until by the U-shaped of the whole circle of standpipe
The cutting of facade 5 is completed；
5th step：Using burning torch, first cut along the both sides U-lag knuckle 7 of riser end U-type groove line of cut,
Burning torch is used again, is cut along the semicircle line of cut below U-lag；Now, the iron block of cutting U-lag formation is cut with standpipe
Open, iron block is taken out；Cutting mode above is repeated, until the U-lag knuckle 7 of the whole circle of standpipe, U-lag semicircle 6 are cut
Complete.
6th step：The first step is repeated to the 5th step, continues to cut the standpipe U-lag of adjacent position：Until by bed rearrangement conduit
The standpipe U-lag cutting of frame is completed.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, it is all
It is any simple modification, equivalent variations and the modification made according to the technical spirit of the present invention to above example, still falls within
In the range of technical solution of the present invention.
