Description
Technical field
The present invention relates to shipbuilding technical fields, and in particular to a kind of vertical batch group welder of the fence group of large ship
Dress and assembly welding method.
Background technique
Large ship deck panel has nearly 1000 fence groups are vertical to need molding making in the production process, and the fence is small
The vertical part of group is mainly by 120 square tubes (the main railing as fence) and 60 square tubes (as the middle column being located between a pair of main railing
Bar) be spliced, height about 2.6 meters, 1-10 meter of length are differed, conventional fence group stand assembly welding method there are it is following not
Foot:
First is that needing a large amount of molding making place；Second is that the specification pattern that group is stood is more；Need to draw more ground
Line-transect；Third is that needing repeated measurement relative dimensions in manufacturing process；Fourth is that can not once complete when welding, need to turn over welding；
Fifth is that not can guarantee in welding process to the control of deformation；Sixth is that producing efficiency is low, it is unable to satisfy the demand of sectional.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of vertical batch group mounted welder of the fence group of large ship and group weldering
Method, it is intended to the defect for the assembly welding method for overcoming fence group in the prior art vertical, improve the vertical group weldering efficiency of fence group and
Quality.Specific technical solution is as follows:
A kind of vertical batch group mounted welder of the fence group of large ship, including its length direction is horizontally disposed a pair of long
Bar shaped band steel, a pair of of strip band steel is parallel to each other and arranged for interval, and the big plane of the strip band steel is opposite
It is arranged in horizontal plane, between the following position of a pair of of strip band steel is provided with along the length direction of the band steel
Every the support frame of distribution, the top position of the strip band steel across be connected with it is a number of being spaced apart and with it is described flat
The vertical group of the length direction of steel welds locating template, and the top position of described group of weldering locating template offers a number of interval cloth
That sets carries out the intermediate rail locating slot of the intermediate rail positioning of fence for fence group immediately.
In use, the tubing being initially switched off in advance (intermediate rail) is directly placed into a group intermediate rail locating slot for weldering locating template
It is interior, it realizes the accurate positionin of intermediate rail spacing, then main railing is assembled in the both ends of intermediate rail, the straight of fence can be carried out
Connect positioning and welding.
