Abstract
The utility model discloses a kind of special toolings for pipeline internal weld seams quality examination, this tooling includes two disks, endoscope and long bolt, two disk parallel intervals are arranged and diameter is less than pipeline inner ring diameter, two disk disk equidistant intervals open up through-hole, long bolt is penetrated the through-hole of two disk disks and the position of two disks is fixed using nut, and endoscope is held between two disks and lens direction and disk are radially consistent.This tooling facilitates the endoscopy for implementing butt weld inside pipeline, and endoscope can be driven to move and rotate along inner wall of the pipe, to find position while welding and accurate and clearly observe, improves the efficiency of Inspection.
Description
Technical field
The utility model is related to a kind of special toolings for pipeline internal weld seams quality examination.
Background technology
After Pipeline butt connects, since pipeline is longer, can not observe inside pipeline the apparent condition of butt weld and
With the presence or absence of surface defect, thus have no way of judging weldquality.For more demanding pipeline, weld seam generally use ultrasonic wave etc.
It is detected, and the weld seam state inside general pipeline generally use endoscopy pipeline, but endoscope is placed directly in pipe
When inside road, it is impossible to it is accurate to find position while welding and observe entire weld seam, endoscope need to be driven to move and rotate along inner wall of the pipe,
Weld seam and accurate and clearly observe can be found.
Invention content
The technical problem to be solved by the utility model is to provide a kind of for the special of pipeline internal weld seams quality examination
Tooling, this tooling facilitate the endoscopy for implementing butt weld inside pipeline, endoscope can be driven to be moved simultaneously along inner wall of the pipe
Rotation to find position while welding and accurate and clearly observe, improves the efficiency of Inspection.
In order to solve the above technical problems, the utility model includes two for the special tooling of pipeline internal weld seams quality examination
A disk, endoscope and long bolt, described two disk parallel intervals arrangement and diameter are less than pipeline inner ring diameter, and described two
A disk disk equidistant interval opens up through-hole, and the long bolt is penetrated the through-hole of described two disk disks and fixed using nut
The position of two disks, the endoscope is held between described two disks and lens direction and disk are radially consistent.
Further, the through-hole of described two disk disks is at least three, and the long bolt is at least three.
Further, described two disks are wooden disks and spacing is 200mm.
Further, after length >=welding of the long bolt pipeline length.
Further, this tooling further includes rubber pad, and the rubber pad is set between the endoscope and disk.
Since the special tooling that the utility model is used for pipeline internal weld seams quality examination employs above-mentioned technical proposal, i.e.,
This tooling includes two disks, endoscope and long bolt, and it is straight that two disk parallel interval arrangements and diameter are less than pipeline inner ring
Diameter, two disk disk equidistant intervals open up through-hole, and long bolt penetrates the through-hole of two disk disks and fixes two using nut
The position of a disk, endoscope is held between two disks and lens direction and disk are radially consistent.This tooling facilitates reality
The endoscopy of butt weld inside pipeline is applied, endoscope can be driven to move and rotate along inner wall of the pipe, to find weld seam position
It puts and accurate and clearly observe, improves the efficiency of Inspection.
Description of the drawings
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the special tooling schematic diagram that the utility model is used for pipeline internal weld seams quality examination；
Fig. 2 is disk schematic diagram in this special tooling.
Specific embodiment
Embodiment is as shown in Figure 1, the utility model includes two for the special tooling of pipeline internal weld seams quality examination
Disk 1, endoscope 2 and long bolt 3, described two 1 parallel intervals of disk are arranged and diameter is less than pipeline inner ring diameter, described
Two 1 disk equidistant intervals of disk open up through-hole 11, and the long bolt 3 penetrates the through-hole 11 of described two 1 disks of disk and adopts
Fix the position of two disks 1 with nut 4, the endoscope 2 is held between described two disks 1 and lens direction and circle
Disk 1 is radially consistent.
Preferably, the through-hole 11 of described two 1 disks of disk is at least three, and the long bolt 3 is at least three.
Preferably, described two disks 1 are wooden disks and spacing is 200mm.Wooden disk avoids this tooling in pipe
Inner wall of the pipe is scratched when being dragged in road.
Preferably, after length >=welding of the long bolt 3 pipeline length.The length of long bolt can ensure that two circles
Disk is dragged to position while welding and conveniently rotates long bolt in pipe ends.
Preferably, this tooling further includes rubber pad 5, and the rubber pad 5 is set between the endoscope 2 and disk 1.Rubber
Pad is provided with endoscope effect and protects and make endoscope reliable retention between two disks.
In pipeline internal weld seams quality examination, this tooling is stretched into pipeline inner ring from one end of pipeline, passes through long bolt
Two disks are drawn along inner wall of the pipe, until endoscopy measures position while welding, endoscope can be implemented to check to weld seam at this time,
Period makes two disks be rotated in pipeline by rotating long bolt, you can drive endoscope rotation, so as to entire weld seam into
Row checks；Two disks are pulled out by inner wall of the pipe in company with endoscope by long bolt after having checked.
By the use of this tooling, it can accurately and clearly observe the apparent condition of butt weld inside pipeline and be
No there are surface defects, solve the problems, such as that endoscope is difficult to check butt weld inside pipeline.
