Will affect subsequent weld job in the long piece welding process of tube panel, influence working efficiency.
Therefore, design it is a kind of can overcome insufficient fixed device in the prior art, fixed for long piece post weld heat treatment,
It is those skilled in the art's urgent problem to be solved.
Summary of the invention
In the prior art, that there are sizes is big, uses for the fixed device of used long piece post weld heat treatment when welding procedure
Inconvenient, fixed effect is limited, influences the problems such as implementation of segmentation skip welding；To solve these problems, the present invention provides a kind of novel
The fixed device of long piece post weld heat treatment lay fixed device more convenient, clever by blocking, modular design
Implementation living, suitable for being segmented skip welding；By the effect of bundling belt and strainer, fixed effect is made to be guaranteed.
The present invention adopts the following technical solutions:
The fixed device of long piece post weld heat treatment, which is characterized in that including at least one fixed cell, each fixed cell includes
2 fixed frames, at least one bundling belt and the strainer with bundling belt cooperation；
The fixed frame includes plane rack and support frame；The plane rack width is greater than heat treatment heater width；The support
Frame is higher than plane rack in vertical direction；
For the bundling belt around the outer rim of 2 fixed frames and part to be heated, both ends are separately connected the both ends of strainer.
Preferably, support frame as described above includes the tripod at both ends and the support rod on connection tripod vertex.
Preferably, the bundling belt is the PES ribbon of 10m × 5cm specification；
The strainer is hand-drive strainer, and maximum tension specification is 3T, including fastener and metal end piece.
Preferably, the part to be heated is tube panel.
Preferably, the fixed frame is welded using angle steel.
The present invention has the advantage that
(1) present apparatus is arranged using blocking, and the fixation device of multiple units can be arranged according to fusion length, avoids production overlength
The fixture of size improves the versatility of fixed device；Each fixed cell is easy to carry, install, and optimizes heat treatment matter
The safeguard of amount is conducive to promote thermal treatment quality and efficiency；
(2) each fixed cell is individually fixed, avoids part uneven surface to be heated to the shadow of clamp effect
It rings；
(3) segmentation skip welding can be implemented, be conducive to shorten the construction period, reduce construction cost；
(4) the weld seam heat treatment that can be applied to vertical direction, not vulnerable to job position, spacial influence.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment is the fixed device of long piece post weld heat treatment, applied in the long piece welding procedure of tube panel, to heat
Handling member is tube panel 4.The structure of the tube panel 4 is as shown in Figure 1 to Figure 2；Wherein 41 material of fin of tube panel is SA-387GR91
Heat-resistant high alloy steel, a length of 11900mm of long piece 42 of tube panel, 4 width of tube panel are 3810mm.The present embodiment as shown in Fig. 3 to 5,
Including at least one fixed cell, each fixed cell includes that 2 fixed frames, 1,2 bundling belt 2 and 2 and bundling belt 2 cooperate
Strainer 3.
It states fixed frame 1 to be welded using angle steel, including plane rack 11 and support frame 12.11 width of plane rack is greater than
It is heat-treated 5 width of heater.Support frame as described above 12 is higher than plane rack 11 in the vertical direction of 4 plane of tube panel, three including both ends
The support rod on two tripod vertex of corner bracket and connection.
For the bundling belt 2 around the outer rim of 4 width direction of 2 fixed frames 1 and tube panel, both ends are separately connected the two of strainer 3
End forms a closed circle.After being tightened up device 3 and being tensioned, bundling belt 2 compresses 2 support rods and tube panel 4 of this fixed cell
Outer rim.The support rod and 4 outer rim of tube panel are arc-shaped, therefore can be convenient for sliding of the bundling belt 22 in tightening, while
