Coaxial with first steel pipe on wall, the other end exposes, the butt end as the first steel pipe and the second steel pipe；
On the outer wall of first steel pipe, close at docking end position circumferentially at least one set of institute of equidistant interval setting
Auxiliary straightening component is stated, the auxiliary straightening component is made of code plate, nut and bolt, and code plate one end is connected to the first steel
On the outer wall of pipe, the other end is overhung at the front of steel sleeve bared end, radially there are spacing between the outer wall of the first steel pipe,
And it is fixedly mounted with the nut in end, the bolt is arranged in screw rod end towards the first steel pipe, along the radial screw thread of the first steel pipe
In the nut.
Preferably, it is 2cm that the steel sleeve, which protrudes into the length in the first steel pipe,.
Preferably, the auxiliary straightening component is equipped with 2 groups altogether.
Compared with the prior art, the utility model has the beneficial effect that:
The utility model is with straightening when simple and cleverly structure design efficiently solves current steel pipe overhead connection
Operation difficulty is big, merging precision is difficult to the technical issues of ensureing, improves high-altitude weldquality, reduces production cost, and energy
Enough mitigate hand labor load, practicability is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1 first steel pipe；2 second steel pipes；3 steel sleeves；4 yards of plates；5 nuts；6 bolts.
Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described implementation
Example is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, this field
Those of ordinary skill's every other embodiment obtained without creative efforts, belongs to the utility model
The range of protection.
Fig. 1 is please referred to, the steel pipe docking bar straightening mechanism of the present embodiment includes identical first steel pipe 1 of caliber and the second steel pipe
2, at least one set of auxiliary straightening component and a steel sleeve 3；
Steel sleeve 3 is in short tube shape, and outer diameter is adapted with the internal diameter of the first steel pipe 1, and one end is welded in by the way of spot welding
Coaxial with the first steel pipe 1 on the inner wall of first steel pipe 1, the other end exposes, as docking for the first steel pipe 1 and the second steel pipe 2
End；
On the outer wall of first steel pipe 1, close at docking end position circumferentially at least one set of auxiliary of equidistant interval setting
Straightening component, auxiliary straightening component are made of code plate 4, nut 5 and bolt 6, and 4 one end of code plate is welded on the outer wall of the first steel pipe 1
On, the other end is overhung at the front of 3 bared end of steel sleeve, and radially there are spacing between the outer wall of the first steel pipe 1, and at end
End is fixedly mounted with nut 5, and bolt 6 is arranged in nut 5 with screw rod end towards the first steel pipe 1, along the radial screw thread of the first steel pipe 1.
Wherein, it is 2cm that steel sleeve 3, which protrudes into the length in the first steel pipe 1,.
Above-mentioned auxiliary straightening component can be according to steel pipe pipe diameter size, multi-direction, multi-quantity setting, to guarantee two steel pipes pair
The precision connect.In the present embodiment, auxiliary straightening component is equipped with 2 groups altogether, wherein code plate 4 is L-shaped structure, as shown in Figure 1.
When steel pipe docking bar straightening mechanism with above structure is applied to the operation of overhead connection weld seam, operating method are as follows:
1, bolt 6 is adjusted, keeps the screw rod rod end of bolt 6 and the outer wall of the first steel pipe 1 substantially flush；
2, the second steel pipe 2 is placed on by steel sleeve 3 with butt end the second steel pipe 2 of direction to the first steel pipe 1 of abutting joint
On bared end, preliminary docking is formed；
3, after preliminary docking, then the bolt 6 by adjusting auxiliary straightening component carries out straightening again, until the first steel pipe 1
Reach design requirement with the mismatch of the second steel pipe 2；
4, after the completion of butt weld operation, if it is desired, cleavable fall to assist straightening component.
While there has been shown and described that the embodiments of the present invention, it will be understood by those skilled in the art that:
These embodiments can be carried out with a variety of variations, modification, replacement in the case where not departing from the principles of the present invention and objective
