Description
Technical field
The present invention relates to the positioning devices docked for pipeline with flange.
Background technique
In existing pipeline (the especially pipeline of caliber 76mm -140mm) manufacturing process, flange docking is by 2 people
Take constructing, will use template item or clout pipe is fixed, point is welded in pipe end, while will use in spot welding flange
Pricker silk is fixed, and after assembly, template item and clout pipe are removed, when having solder joint residual, while removing pricker silk, also easily
Break inside weld seam.Such assembly method, spends human and material resources, and construction quality is poor, inefficiency, and it is difficult to ensure that weld pitch
From being influenced in rear road tube welding very big, film making qualification rate is not high.
Summary of the invention
The purpose of the present invention is to provide a kind of pipelines to dock with flange with positioning device, effective improving production efficiency and right
The welding quality of acting flange.
Realizing the technical solution of above-mentioned purpose is:
A kind of pipeline is docked with flange with positioning device, comprising: upper Circumflex branch fagging, lower Circumflex branch fagging, nut, screw thread
Bar, handle and casing, wherein
The bottom center of the upper Circumflex branch fagging is fixedly connected with the threaded rod vertically；
The nut is welded in the upper surface of the head end of the handle, described in the lower surface of the head end of the handle is welded vertically
Casing；
The head end of the handle is provided with through-hole, which is connected to the nut and described sleeve pipe；
The bottom end of described sleeve pipe is fixedly connected with the center of the lower Circumflex branch fagging；
The threaded rod is connect with the nut thread.
Preferably, the aperture of the through-hole and described sleeve pipe is equal, and 2mm bigger than the diameter of the threaded rod.
Preferably, the handle is reversible ratcheting tool.
Preferably, the lower part outer rim of the threaded rod is provided with first positioning hole, and described sleeve pipe is equidistantly opened along the vertical direction
There are multiple second location holes.
The beneficial effects of the present invention are: the present invention can be completed to operate, be promoted by effectively simple structure design by 1 people
Production efficiency, at least improves one times in the fit on of abutted flange, and in terms of the welding quality of abutted flange, reduce
The faults repair of taking X-ray, welding quality level are greatly improved.
Detailed description of the invention
Fig. 1 is that pipeline of the invention docks structure chart with positioning device with flange；
Fig. 2 is the front view of handle in the present invention.
Specific embodiment
The present invention will be further described with reference to the accompanying drawings.
Please refer to Fig. 1 and Fig. 2, pipeline of the invention is docked with flange with positioning device, comprising: upper Circumflex branch fagging 1, under
Circle round support plate 2, nut 3, threaded rod 4, handle 5 and casing 6.
The bottom center of upper Circumflex branch fagging 1 is fixedly connected with threaded rod 4 vertically.
The upper surface welded nut 3 of the head end of handle 5, the vertical soldering sleeve 6 in the lower surface of the head end of handle 5.Handle 5
Head end is provided with through-hole, which is connected to nut 3 and casing 6.In the present embodiment, handle 5 is reversible ratcheting tool.
The bottom end of casing 6 is fixedly connected with the center of lower Circumflex branch fagging 2.Threaded rod 4 is threadedly coupled with nut 3.Lower convolution
2 stationary positioned device of support plate is prevented from sliding relatively, can not be positioned.
The aperture of through-hole and casing 6 is equal, and 2mm bigger than the diameter of threaded rod 4.Ensure that threaded rod 4 can be inserted into set
Pipe 6.The lower part outer rim of threaded rod 4 is provided with first positioning hole, and casing 6 is equidistantly provided with multiple second location holes along the vertical direction.
It is inserted into first positioning hole and second location hole by positioning pin, the position of energy strengthened thread bar 4 is fixed.
In use, pipeline is docked with flange, it is put into positioning device, backspin on threaded rod 4 is adjusted by handle 5
It is dynamic, so that Circumflex branch fagging 1 is withstood on position a, b above pipe end and flange, lower Circumflex branch fagging 2 is withstood in pipe end
Position c, d below mouth and flange.After fitting closely, assembly spot welding is carried out, after assembling spot welding, using handle 5
Cycle threaded rod 4, positioning device is accepted, and waiting uses next time.According to the pipe diameter size of pipeline, Circumflex branch is supportted in setting
The length of the size and threaded rod 4 of plate 1 and lower Circumflex branch fagging 2, so as to cope with different tube diameters abutted flange dress
Match.In the present embodiment, it is mainly used in the pipeline and flange Butt Assembling of caliber 76mm -140mm, improves pipeline production efficiency
And quality.
The present invention can be operated with 1 people and be completed, and compare original two people operation, 1min is achievable till now by original 3min
Assembly greatly improves the assembling speed of flange docking, improves production efficiency.Each ship type bulk freighter caliber 76mm -140mm
1,2 grade of pipe it is as shown in table 1 below:
Table 1
Production 80K BC and 208K BC each one is pressed within one month, therefore total about 810 root canals are sub, 1 root canal is minimum to press dress
With 2 abutted flanges, 1 abutted flange is assembled, promotes 2min, about 0.03h, a month total saving 810*2*0.03=54h；
By 1 people of original 2 people construction till now, 1 people assembles 1 flange and saves 3min, about 0.05h, 1 people of saving in 1 month
Work, about 0.05*810*2=81h can save 54+81=135h in one month.1 calculates for artificial one day by 240 yuan, therefore, one
30 yuan of hour, a month saving 135*30=4050 member can save 4.86 ten thousand yuan in 1 year.Therefore use the present invention, production efficiency
3 times are promoted, while reducing by 1 people, relatively original mode can save 4.86 ten thousand yuan in 1 year.
In the prior art, it will use template item or clout pipe fixed, point is welded in tube end mouth, while in spot welding flange
It will use pricker silk to fix, after assembly, template item and clout pipe removed, have solder joint residual, meanwhile, remove pricker silk
When, it is also easily broken inside weld seam, great inconvenience is caused to electric welding.Generally, after abutted flange welding, it will do it X-ray
Shooting checks weldquality, above solder joint residual and broken pricker silk, easily causes be mingled with Deng welding defects problem, make
At Weld Seam Repairation, it is the tens of welding for the first time that the reprocessing of 1 weld bond, which needs carbon processes, the spent time such as dig, repair, make film again,
Times even hundreds of times, by caliber 76mm -140mm, one of weld bond of about 3 hours.Therefore using the present invention, weldering can be effectively improved
Quality is connect, primary film making qualification rate is improved, reduction is reprocessed.
In conclusion the present invention has, figure is small and exquisite, flexibility and reliability, excellent convenient for operation, the significant, good quality of efficiency etc.
Point.
Above embodiments are used for illustrative purposes only, rather than limitation of the present invention, the technology people in relation to technical field
Member, without departing from the spirit and scope of the present invention, can also make various transformation or modification, therefore all equivalent
Technical solution also should belong to scope of the invention, should be limited by each claim.
