The fixture simplifies the procedure of arrangement and disassembly of a base plate, accelerates the adjustment speed and saves half of the time, compared to the conventional method.

Description

Jig
Technical field:
The utility model relates to a kind of mammoth conveter engineering hinged swing column erecting tools, particularly a kind of jig.
Background technology:
Steel-making factory building swing column be positioned at build stride with traversing boundary axis of striding on, build because of arts demand and to stride the roofing elevation design and exceed traversing striding, consider temperature contraction distortion, adopt at the traversing roofing capital end of striding hinged swing column is set avoids temperature deformation on the impact of whole roof structure.The defective that tradition construction tool and job practices produce is: the gap pads, welds at the bottom of adopting backing plate with post, causes absolute altitude and verticality to adjust difficulty; Adopt the wire rope control verticality that matches with Chain block, adjustment mode backwardness; Security incident easily occurs in installation process, and time-consuming taking a lot of work.
The utility model content:
The utility model is intended to solve the problem that traditional swing column erecting tools is difficult to guarantee installation accuracy and safety, and a kind of jig that is easy to regulate and can repeat to have enough to meet the need use is provided, with safe and reliable, simple and easy quick, the time saving and energy saving purpose of the installation that reaches swing column.
Jig of the present utility model adopts following technical scheme:
A kind of jig comprises adjustable supporting brace, fixing hanger, and described adjustable supporting brace is the two-part structure, connects by bolt tensioner between two sections, and these adjustable supporting brace two ends are hinged by connecting pin and described fixedly hanger.
Adopt the utility model of technique scheme compared with prior art, have following advantage: installs simple and easy, convenient adjusting and fixing swing column; Jig can infinitely reuse; Solve the adjustment of swing column verticality and fixing difficulty; Improve the safety of the installation of swing column and follow-up structure, accelerate the installation rate of swing column.The operation of using the method to simplify setting, remove backing plate is accelerated the adjustment progress, saves the time of half than the method for routine.
Preferred version of the present utility model is:
Nut and key seat are equipped with respectively in the two ends of each section in the adjustable support arm of described two-part structure, this key seat and described by connecting pin and fixedly hanger is hinged; Connect by bolt tensioner between the nut in the described two-stage structure.
The adjustable support arm of described two-part is made by two sections seamless steel pipes.
Description of drawings:
Fig. 1 is the structural representation of the utility model jig.
Fig. 2 is that an end of jig is contained in the structural representation on the swing column.
Fig. 3 is the lateral view of Fig. 2.
Fig. 4 swing column and jig and joist, roof girder syndeton schematic diagram.
Fig. 5 is the lateral view of Fig. 4.
Among the figure: the first fixing fixedly hanger 8, the second connecting pin 9, the first connecting pin 10, the second nut 11 of hanger 1, the first key seat 2, first paragraph adjustable supporting brace 3, the first nut 4, slack adjuster 5, second segment adjustable supporting brace 6, the second key seat 7, second; Swing column 12, the first joist 13, the second joist 14, roof girder 15.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail:
A kind of jig, by the adjustable supporting brace and fixedly hanger consist of, the adjustable supporting brace is the two-part structure, respectively first paragraph adjustable supporting brace 3 and second segment adjustable supporting brace 6, be connected by bolt tensioner 5 between 6 two sections of the first adjustable supporting brace 3 and the braces of second segment adjustable supporting, adjustable supporting brace two ends respectively by the first connecting pin 10 and the second connecting pin 9 and first fixedly hanger 1 and second fixedly hanger 8 is hinged.
Nut and key seat are equipped with respectively in the two ends of each section in the adjustable support arm of two-part structure, two sections of first paragraph adjustable supporting brace 3 are equipped with respectively the first nut 4 and the first key seat 2, and the second nut 11 and the second key seat 7 are equipped with respectively in the two ends of second segment adjustable supporting brace 6; Connect by bolt tensioner between the nut in the two-stage structure; The first nut 4 be connected nut 11 and connect by slack adjuster 5, the two ends of slack adjuster 5 are provided with screw rod, screw rod respectively with the first nut 4 be connected nut 11 and be connected.
Key seat is by connecting pin and fixedly hanger is hinged; Be convenient to dismounting, can reach the purpose of the unlimited recycling of jig.The first key seat 2 by the first connecting pin 10 with first fixedly hanger 1 be connected; The second key seat 7 by the second connecting pin 9 with second fixedly hanger 8 be connected.
The adjustable support arm of two-part is made by two sections seamless steel pipes; First paragraph adjustable supporting brace 3 and second segment adjustable supporting brace 6 are made by one section seamless steel pipe respectively.The specification of seamless steel pipe is: DN108 * 4mm * 800m;
The specification of connecting pin is: 9mm * 60mm.
In the free-ended situation in the second adjustable supporting brace 6, an end of the first adjustable supporting brace 3 respectively can around first fixedly hanger 1 do the rotations of 180 degree; In the free-ended situation in the first adjustable supporting brace 3, an end of the second adjustable supporting brace 6 can around second fixedly hanger 8 do the rotations of 180 degree.
With the method for the hinged swing column of jig installation mammoth conveter engineering, carry out in accordance with the following steps:
On the ground with 12 two corresponding faces of swing column and with the perpendicular face of these two faces on the first fixing hanger 1 of Clamp for welding one end respectively; Connect a jig on each face, amount to three jigs.
By crane with swing column 12 and factory building columns hinged in place after, with the jig other end second fixedly hanger 8 be welded on the joist top flange plate and on the top flange plate of roof girder; Wherein have two second fixedly hanger 8 be welded in respectively on the top flange plate of the first joist 13 and on the top flange plate of the second joist 14.In the 3rd jig second fixedly hanger 8 is welded on the top flange plate of roof girder 15.
Reach the verticality of adjusting swing column 12 by slack adjuster 5 adjusting length and reach fixedly swing column;
Treat that hinged swing column 12, roof girder 15 install with vertical support, reach rock-steady structure and through after the assay was approved, with the jig dismounting, be used for subsequent installation.
