The utility model embodiment provides a kind of submerged-arc welded (SAW) pipe pipe end ovality self-operated measuring unit, such as accompanying drawing 1, accompanying drawing
2nd, shown in accompanying drawing 3, the device includes bearing 1, and driven roller 2 is arranged on the upper end of bearing 1, for being driven under the control of electric rotating machine 3
Welded tube 6 to be measured is rotated；Two groups of measurement assemblies 4, are movably oppositely arranged on the two ends of bearing 1.Measurement assembly 4 includes：It is removable
Dynamic support 401；Vertical support arm 402, is arranged on the top of movable supporting frame 401；Two horizontal mounting arms 403, are set height adjustable
Overlapped in the upper and lower part of vertical support arm 402, and with the mouth of pipe two end portions of welded tube 6 to be measured；Laser range sensor 404
Transmitter 4041 and receiver 4042, be oppositely arranged on the two ends of each horizontal mounting arm 403；Range sensor 405, is arranged on
On vertical support arm 402.The device also includes：Movable motor 5, is arranged on movable supporting frame 401, for driving movable supporting frame
401；Movable motor 5, range sensor 405, laser range sensor 404 are connected to slave station by the first communication cable, from
Stand and main website is connected to by the second communication cable, main website is wirelessly connected to host computer.
The operation principle for the submerged-arc welded (SAW) pipe pipe end ovality self-operated measuring unit that the utility model embodiment is provided is as follows：
First, welded tube 6 to be measured is placed on bearing 1, starts electric rotating machine 3, rotate welded tube 6 to be measured, meanwhile,
Drive the measurement assembly 4 at the two ends of bearing 1 close to the end of welded tube 6 to be measured by movable motor 5, pass through range sensor
405 the distance between detection measurement assemblies 4 and welded tube 6 to be measured, and the range data measured is passed through into the first communication electricity in real time
Cable is transferred to slave station, and range data is transferred to main website by the second cable again, analyzed by main website by slave station.Work as measurement assembly
4 reach after preset distance with the distance of the pipe end of welded tube 6 to be measured, and main website sends stop signal by slave station to movable motor 5, this
When the guiding measuring component 4 of movable motor 5 be parked in position suitable for measurement welded pipe end ovality just.Then main website passes through slave station
Working signal is sent to laser range sensor 404, laser range sensor 404 starts the diameter to the pipe end of welded tube 6 to be measured
Measure.The diameter data measured (multigroup diameter of the pipe end of welded tube 6 i.e. to be measured) is passed through by laser range sensor 404
One communication cable is transferred to slave station, and diameter data is transferred to main website by slave station by the second communication cable, and main website is to multigroup to be measured
The amount tube end diameter value of welded tube 6 is compared, and the difference for calculating the diameter D1 of maximum and the diameter D2, D1 and D2 of minimum is to treat
Measure the ovality of the pipe end of welded tube 6.The ovality calculated is transferred in host computer by main website, is shown ovality by host computer
Show to come, operating personnel's reading numerical values, you can complete the automatic measurement of submerged-arc welded (SAW) pipe pipe end ovality.
It is as follows to the measuring principle of the tube end diameter of welded tube 6 to be measured on laser range sensor 404：
Because two horizontal mounting arms 403 overlap (referring to accompanying drawing 3 and accompanying drawing 4) with the mouth of pipe two end portions of welded tube 6 to be measured,
That is the mouth of pipe two of the top of the horizontal mounting arm 403 of the bottom of the horizontal mounting arm 403 on top and bottom respectively with welded tube 6 to be measured
End is overlapped, and the light curtain that the light curtain and receiver 4042 sent due to the transmitter 4041 of laser range sensor 404 is received has
Have an one fixed width, and upper level support arm 403 laser range sensor 404 send the top edge of light curtain will not be by weldering to be measured
The mouth of pipe of pipe 6 stops, the lower edge that the laser range sensor 404 of lower horizontal support arm 403 sends light curtain will not be to be measured
The mouth of pipe of welded tube 6 stops.As shown in Figure 4, the width between two groups of laser range sensors 404 is designated as L1 (L1 can pass through
The actual measurement of the survey tools such as ruler is obtained), i.e., laser range sensor 404 sends the upper of light curtain on upper level support arm 403
Edge sends the distance between lower edge of light curtain for L1 with laser range sensor 404 on lower horizontal support arm 403.It is to be measured
The bottom that the top of the tube wall of welded tube 6 can send light curtain to top laser range sensor 404 produces certain stop, top laser
Distance measuring sensor 404 sends the width that light curtain is not blocked and is designated as L2, and the bottom of the tube wall of welded tube 6 to be measured can be to bottom Laser Measuring
The top for sending light curtain away from sensor 404 produces certain stop, and bottom laser range sensor 404 sends light curtain and is not blocked
Width be designated as L3, now the diameter of the pipe end of welded tube 6 to be measured is D=L1-L2-L3, i.e., two groups laser range sensors 404
The data actually measured are the diameter values of the pipe end of welded tube 6 to be measured, and because welded tube in measurement process can also be in driven roller 2
Effect is lower to produce rotation, and two groups of laser range sensors 404 can just collect multigroup tube end diameter value of welded tube to be measured 6, lead to
The difference for crossing diameter D1 and minimum diameter D2, D1 and D2 that main website calculates maximum is the ellipse of the pipe end of welded tube 6 to be measured
Degree.
