Description
Technical field
The present invention relates to Pipe installing field, specifically a kind of portable large-scale pipeline welding contra-aperture device and user
Method.
Background technology
Site welding when being installed for large-scale pipeline, since there are fabrication error, transports to deform equal error for pipeline itself,
It is exceeded to often lead to pipeline mismatch amount in welding, seriously affect the quality of pipeline welding.
Invention content
It is an object of the invention to overcome drawbacks described above, a kind of counterpart dress for control pipeline group pair when welding is provided
It sets and its application method.
In order to achieve the above object, the invention is realized in this way：
A kind of portable large-scale pipeline welding contra-aperture device, including annular retainer, pressing plate and clamping screw, wherein annular is protected
It holds frame to be set at the group abutment joint of two pipelines, pressing plate has polylith and is distributed on the inside of annular retainer, the medial surface of pressing plate
The outer wall with two pipelines offsets respectively, and clamping screw is arranged in the outside of pressing plate；The clamping screw passes through annular retainer,
It is connect by tapped through hole between annular retainer, by rotating clamping screw, to make pressing plate tight against in pipeline outer wall
On.
The application method of the portable large-scale pipeline welding contra-aperture device, including
Step 1, the position for adjusting pipeline to be welded, absolute altitude and weld bond gap,
Step 2, basis wait for that group makes annular retainer to the outer diameter of pipeline, which is in two-flap type, fixed by being arranged
Position plate and two valve annular retainers are spliced into integral annular retainer；
Step 3 installs annular retainer according to the weld bond position of pipeline,
Step 4, the position that each pressing plate on annular retainer is distributed according to the adjustment of the mismatch amount of pipeline enclosure, are locked by adjusting
Bolt makes pressing plate push pipeline movement, finally makes two sections to wait for the pipeline phase split of group pair and mismatch amount meets technological standards；
Step 5 starts pipeline location welding；
This contra-aperture device is removed after the completion of step 6, welding.
This contra-aperture device is applied in the welding counterpart construction of large-scale pipeline, the present apparatus is fixed on the outside of pipeline, is led to
It overregulates and is looped around at pipeline butt taxi driver brother to pressing plate, to effective falling tone homogeneous tube road unfitness of butt joint, the present apparatus is easy to operate, makes
It is convenient, effectively reduce working sources and pipeline adjustment time.
Description of the drawings
Fig. 1 is the structural schematic diagram one of the present apparatus.
Fig. 2 is the structural schematic diagram two of the present apparatus.
Specific implementation mode
It is further illustrated the present invention below by way of specific embodiment.
As shown in Figure 1 and Figure 2, a kind of portable large-scale pipeline welds contra-aperture device, including annular retainer 1,2 and of pressing plate
Clamping screw 3, wherein annular retainer 1 is set at the group abutment joint of two pipelines 4, and pressing plate 2 has polylith and is distributed on annular
The inside of retainer 1, the outer wall of the medial surface of pressing plate 2 respectively with two pipelines 4 offset, and clamping screw 3 is arranged in the outside of pressing plate 2；
The clamping screw 3 passes through annular retainer 1, is connect by tapped through hole between annular retainer 1, passes through rotation lock
Tight bolt 3, to make pressing plate 2 tight against on 4 outer wall of pipeline.
The application method of the portable large-scale pipeline welding contra-aperture device, including
Step 1, the position for adjusting pipeline 4 to be welded, absolute altitude and weld bond gap,
Step 2, basis wait for that group makes annular retainer 1 to the outer diameter of pipeline, which is in two-flap type, passes through setting
Positioning plate and two valve annular retainers are spliced to integral annular retainer 1；
Step 3 installs annular retainer 1 according to the weld bond position of pipeline 4,
Step 4, the position that each pressing plate 2 on annular retainer 1 is distributed according to the mismatch amount adjustment between pipeline 4, pass through adjusting
Clamping screw 3 makes pressing plate 2 that pipeline 4 be pushed to move, and finally makes two sections to wait for the 4 phase split of pipeline of group pair and mismatch amount meets technique
Standard；
Step 5 starts pipeline location welding；
This contra-aperture device is removed after the completion of step 6, welding.
This contra-aperture device is applied in the welding counterpart construction of large-scale pipeline, the present apparatus is fixed on the outside of pipeline, is led to
It overregulates and is looped around at pipeline butt taxi driver brother to pressing plate, to effective falling tone homogeneous tube road unfitness of butt joint, the present apparatus is easy to operate, makes
It is convenient, effectively reduce working sources and pipeline adjustment time.
