Description
Technical field
The utility model relates to the elbow assembly welding, the special measurement device of specifically a kind of definite elbow assembly welding position.
Background technology
The mountain area pipeline construction is because with a varied topography, and pipeline need use elbow more, and to a certain extent, the work efficiency when the duct segments construction connects determines the progress of whole engineering.Common way was after the pipeline section pigging pipeline purging of having welded, to measure angle between two pipeline sections when mountain area pipeline construction in the past connected; The required elbow of prefabricated connection is treated behind the pipeline hyposulculus the prefabricated elbow of welding again, owing to there is not special-purpose survey instrument; Prefabricated elbow group is bigger to weld bond position dimension error; And because the assembly welding of two pipeline section center lines when elbow is connected difficulty very, generally need to organize success through reconditioning repeatedly; Cause site operation personnel's labour intensity big, operating efficiency is low, and influences construction quality.So demand a kind of measurement mechanism that is used for confirming elbow assembly welding position specially that can solve above-mentioned defective urgently.
Summary of the invention
The purpose of the utility model is the defective that exists to prior art, and the special measurement device of a kind of definite elbow assembly welding position is provided.Utilize the mountain area pipeline construction to confirm that elbow connects the measurement mechanism of assembly welding position; Carry out between two pipeline sections that field measurement confirms to have constructed the connecting bend group to the position of weld bond; Confirm the relative space position of two pipeline sections, remain in the same plane after making two pipeline section axial lines adjustment.Improve the elbow assembly welding installation accuracy, increase work efficiency and the pipeline construction quality.
The utility model solves the technical scheme that its technical matters adopted: the special measurement device of a kind of definite elbow assembly welding position, this measurement mechanism are two groups and are installed on respectively in the pipeline that will be welded on same elbow two ends; Measurement mechanism in each pipeline comprises measuring center bar and the reducing expansion link that is installed on the saddle; The axis of said measuring center bar is fit to the axis of pipeline, and said reducing expansion link one end connects saddle and perpendicular to the measuring center bar, other end contact inner-walls of duct and perpendicular to inner-walls of duct.
Said reducing expansion link is that the leg conduit is provided with the set nut that is used for locking the reducing expansion link in three three leg conduits that all are placed in saddle.
Said measuring center bar can be flexible along conduit axis in saddle, and saddle is provided with and is used for the trip bolt of fastening measuring center bar.
The special measurement device of a kind of definite elbow assembly welding position of the utility model is compared with prior art, has following beneficial effect:
The pipeline construction of the utility model mountain area confirms that elbow connects the measurement mechanism of assembly welding position; Carry out between two pipeline sections that field measurement confirms to have constructed the connecting bend group to the position of weld bond; Confirm the relative space position of two pipeline sections, remain in the same plane after making two pipeline section axial lines adjustment.Improve the elbow assembly welding installation accuracy, increase work efficiency and the pipeline construction quality.The two pipeline section center lines of having stopped the prior art existence are not often in a plane; Assembly welding when elbow is connected is difficulty very; Generally need to organize success, cause site operation personnel's labour intensity big, operating efficiency is low, and influence some defectives such as construction quality through reconditioning repeatedly.

Embodiment
Next explanation at length below with reference to Figure of description the special measurement device of a kind of definite elbow assembly welding position of the utility model being done.
The special measurement device of a kind of definite elbow assembly welding position; This measurement mechanism is two groups of (elbow assembly welding position-measurement devices in the A. pipeline section I; B. the elbow assembly welding position-measurement device in the pipeline section II) be installed on respectively the pipeline that will be welded on same elbow two ends (I. the pipeline section I that is connected with elbow, II. the pipeline section II that is connected with elbow) in; Measurement mechanism in each pipeline comprises measuring center bar 4 and the reducing expansion link 3 that is installed on the saddle 1; The axis of said measuring center bar is fit to the axis of pipeline, and said reducing expansion link one end connects saddle and perpendicular to the measuring center bar, other end contact inner-walls of duct and perpendicular to inner-walls of duct.Said reducing expansion link is that the leg conduit is provided with the set nut 2 that is used for locking the reducing expansion link in three three leg conduits that all are placed in saddle.Said measuring center bar can be flexible along conduit axis in saddle, and saddle is provided with and is used for the trip bolt of fastening measuring center bar.
Saddle is welded by Ф 27x4 weldless steel tube and with two groups of perpendicular (three every group) Ф 18x3 weldless steel tubes of its axis.Reducing expansion link and measuring center bar are made by Ф 12 round steel.
When concrete use is measured: regulate the flexible size that is installed on two groups of reducing expansion links 3 on the saddle 1 according to the size of the pipeline section I of having constructed, pipeline section II caliber earlier; Make the radial dimension of confirming elbow assembly welding position-measurement device identical, then with the fixing reducing expansion link 3 of set nut 2 with the pipeline section internal diameter of having constructed.
The extension L of adjustment measuring center bar 4; (L=om=on, O point are measuring center bar 4 summits, and the m point is the end points of elbow assembly welding position-measurement device A saddle 1 to make the L value; The n point is the end points of elbow assembly welding position-measurement device B saddle 1) equate (L value Theoretical Calculation: L=R*Sin α/2 with calculated value; In the formula, R-elbow bending radius, α-elbow bending angle).Extension L value confirms that the back is fixing with trip bolt 5.
A puts into the pipeline section I with elbow assembly welding position-measurement device, makes the end points m of elbow assembly welding position-measurement device A saddle 1 and the mouth of pipe flush of pipeline section I.
