Abstract

A method of mismatch being docked using jack centering pipeline, belongs to the large and medium-sized Tube formation technical field of industry.Step: the first segment pipe (1) is grouped with the second segment pipe (2), in group to interface (3) position elder generation welding flattening one end (4);Jack (5) is fixed on to the port position fixed point (6) of the second segment pipe (2) of deformation, jack (5) other end hangs over the symmetric position fixed point (7) of the pipeline;Jack (5) hand-manipulated, the second segment pipe (2) port of jack (5) with dynamic deformation, keeps the second segment pipe (2) port gradually concordant with the first segment pipe (1) port;After the first segment pipe (1) is concordant with the second segment pipe (2) port, welding adjusts concordant pipe end (8);Jack (5) are unloaded, adjustment deformation position is further continued for, until the first segment pipe (1) has been welded and fixed with the second segment pipe (2) correction.The advantage is that it is simple to operation, and do not have to the auxiliary materials such as support rod, pipe string efficiency is substantially increased, material is saved, reduces construction cost.

Description

A method of mismatch is docked using jack centering pipeline
Technical field
The invention belongs to the large and medium-sized Tube formation technical fields of industry, in particular, provide a kind of use jack centering pipeline The method for docking mismatch.
Background technique
When industrial large and medium-sized Tube formation, for deformable duct, branch support shield inside pipeline is generally mostly used, and cooperate thousand Jin top is adjusted correction, consumes a large amount of backing materials, while it is slower to operate jack, time-consuming.
Summary of the invention
The purpose of the present invention is to provide a kind of methods using jack centering pipeline docking mismatch to sintering large flue Group is in the process, and using jack (bottle gouard moved by hands) operation adjustment pipe deforming, centering pipeline docks mismatch, and achieves success. It realizes simple to operation, and does not have to the auxiliary materials such as support rod, substantially increase pipe string efficiency, save material, drop Low construction cost has been gained most valuable experience for similar construction later.
The present invention is when group is to pipeline, first welding flattening one end, and it is larger that jack (bottle gouard moved by hands) is then fixed on deformation The port position of size pipeline, the jack other end hang over the symmetric position of the pipeline, then jack hand-manipulated, and jack, which drives, to be become Shape pipeline keeps pipe end gradually concordant to pipe end with another group, after two pipe ends are concordant, is welded and fixed.It unloads down Chain is further continued for adjusting other deformation positions, until two groups have been welded and fixed pipeline correction.Specific step is as follows:
The first step, the first segment pipe 1 are grouped with the second segment pipe 2, in group to 3 position elder generation welding flattening one end of interface 4 (Fig. 1);
Jack (bottle gouard moved by hands) 5 is fixed on the port position fixed point 6 of the second segment pipe 2 of deformation, jack by second step 5 other ends hang over the symmetric position fixed point 7 (Fig. 2) of the pipeline;
Third step, jack 5 hand-manipulated, second segment pipe 2 port of the jack 5 with dynamic deformation make 2 port of the second segment pipe Gradually (Fig. 3) concordant with 1 port of the first segment pipe;
4th step, after the first segment pipe 1 is concordant with 2 port of the second segment pipe, welding adjusts concordant pipe end 8.It unloads Jack 5 is further continued for adjusting other deformation positions, until (Fig. 4) has been welded and fixed in the first segment pipe 1 and the correction of the second segment pipe 2.
This method is simple to operation, and does not have to the auxiliary materials such as support rod, substantially increases pipe string efficiency, saves Material reduces construction cost, achieves good economic benefit for company.
Detailed description of the invention
Fig. 1 is the first segment pipe and second segment pipe string figure.
Fig. 2 is the station diagram that jack is mounted on second segment pipe deforming.
Fig. 3 is operation jack, corrects second segment pipe deforming figure.
Fig. 4 is that figure is welded and fixed after second segment pipe deforming corrects.
In figure, the first segment pipe 1, the second segment pipe 2, group are solid to interface 3, welding flattening one end 4, jack 5, port position Fixed point 6, symmetric position fixed point 7, welding adjust concordant pipe end 8.
Specific embodiment
Fig. 1-Fig. 4 is a kind of specific embodiment of the invention.Specific embodiment is as follows:
The first step, the first segment pipe 1 are grouped with the second segment pipe 2, in group to 3 position elder generation welding flattening one end of interface 4;
Jack (bottle gouard moved by hands) 5 is fixed on the port position fixed point 6 of the second segment pipe 2 of deformation, jack by second step 5 other ends hang over the symmetric position fixed point 7 of the pipeline;
Third step, jack 5 hand-manipulated, second segment pipe 2 port of the jack 5 with dynamic deformation make 2 port of the second segment pipe It is gradually concordant with 1 port of the first segment pipe;
4th step, after the first segment pipe 1 is concordant with 2 port of the second segment pipe, welding adjusts concordant pipe end 8.It unloads Jack 5 is further continued for adjusting other deformation positions, until the first segment pipe 1 has been welded and fixed with the correction of the second segment pipe 2.
