The side in the axle center of the threaded hole of coil is in type with 1211 one of support bar.
The cross sectional shape of the limiting slot 1213 can be trapezoidal or arc-shaped, in the present embodiment, the limiting slot 1213
Shape be it is trapezoidal, it is of course possible to understand ground, the cross sectional shape of the limiting slot 1213 be not limited to it is trapezoidal or arc-shaped, can for length
It is rectangular or rectangular, then the supporting section 1211 be equipped with limiting slot 1213 one side be interdigitated electrode structure structure, the supporting section 1211 back to
The one side of the limiting slot 1213 is planar structure.An at least pipeline section for the heat-transfer pipe 20 is set in the limiting slot 1213, and at this
Another support bar opposite with the limiting slot 1213 of limiting slot 1213 clamps lower clamping, to fix the heat-transfer pipe 20.
The limiting slot 1213 and adjacent supports item form idle space, the pipe of the size of the accommodating space and the heat-transfer pipe 20
The outer diameter of section is adapted, in order to which the pipeline section of the heat-transfer pipe 20 to be fastened in the accommodating space, to fix the heat-transfer pipe 20, then
The size of the accommodating space can it is slightly larger or slightly smaller in or equal to the heat-transfer pipe 20 pipeline section outer diameter.This further, the limit
Position slot 1213 and adjacent supports item form accommodating space, and the outer diameter of pipeline section of the size and heat-transfer pipe of the accommodating space is suitable,
Consolidate so that the pipeline section of the heat-transfer pipe 20 carries out clamping with the plane of adjacent support bar by the inner surface of the limiting slot 1213
It is fixed.
In the present embodiment, which includes the several layers helix tube for being disposed radially and being mutually arranged,
Each layer of helix tube includes several along pipeline section axially arranged side by side, and the pipeline section of same layer helix tube is between two support bars along vertical
Direction arrangement；Each limiting slot 1213 is arranged in a one-to-one correspondence with the pipeline section for being located on the same floor helix tube, is located on same support bar
Limiting slot 1213 quantity it is equal with the quantity for the pipeline section for being located on the same floor helix tube so that all pipeline sections of the helix tube
It can be fastened on the limiting slot 1213.In the present embodiment, which is obliquely installed in the axial direction, inclination
The inclined angle of pipeline section of heat-transfer pipe 20 of the corresponding setting of angle be adapted, to guarantee that the limiting slot 1213 can be stablized
It is arranged in the accommodating space.
Further, in the present embodiment, the side of all support bars 121 in the support component 12 is equipped with limiting slot
1213, the limiting slot 1213 on these support bars 121 is arranged at back on the side wall in sleeve axle center, in same radial direction
On.The inner sidewall of limiting slot 1213 and sleeve on outermost support bar 121 forms accommodating space, the accommodating space
Size is suitable with the outer diameter of the pipeline section of the heat-transfer pipe 20；Specifically, three planes of the dovetail groove are formed with the curved surface of sleeve 11
Accommodating space, so that the pipeline section of the heat-transfer pipe 20 can be by three planes of the dovetail groove and the curved surface card of sleeve 11
Tightly.Limiting slot 1213 on remaining support bar 121 forms accommodating space with a support bar being arranged in contrast, and the accommodating is empty
Between size it is suitable with the pipeline section outer diameter of the heat-transfer pipe 20 so that the pipeline section of the heat-transfer pipe 20 can have three of the dovetail groove
One plane of its opposite limiting slot of plane and an adjacent support bar carries out clamping, and all support bars 121 are solid by this
It is fixed to determine part 122, so that relative displacement can not occur between the heat-transfer pipe 20 and support bar 121, and then avoids heat-transfer pipe
It is scratched or wears.
The one or both ends in the support bar 121 can be set in the fixing piece 122.In this embodiment, it is preferred that should
The both ends of the support bar are arranged in fixing piece 122.In the present embodiment, which can be rectangular-shape, its length
Width more than or equal to all support bars and the summation plus the spacing sum between all support bars.The one of the fixing piece 122
Side is arranged in the inner sidewall of the sleeve 11 and is disposed radially；It can weld the inner sidewall in the sleeve 11 to avoid the fixing piece
122 is mobile.The fixing piece 122 is equipped with the through-hole 1221 connecting with the linkage section 1212, when installing the heat-transfer pipe 20, can incite somebody to action
After the support bar 121 is fixed with each layer of heat-transfer pipe 20 respectively, then the linkage section 1212 of every support bar plugs in through-holes, and
Can by the way that the linkage section 1212 and the through-hole 1221 are welded and fixed so that all pipeline sections of the heat-transfer pipe 20 with should
Relative displacement can not occur between support bar 121.
Fig. 4 to fig. 6 shows the second embodiment of present invention heat transfer tube support device.The second embodiment and first reality
The difference for applying example is, in the second embodiment, the cross sectional shape of the limiting slot 1213 is arc-shaped.The heat-transfer pipe is by the circular arc
The plane of the curved surface of shape slot its opposite limiting slot 1213 of support bar 121 adjacent with this carries out clamping fixed.
Above embodiments heat transfer tube support device has the advantage that
1. being applicable to small spacing heat-transfer pipe, the especially support of helix tube；
2. support bar 121 of the invention can be plugged in the through-hole 1221 of fixing piece 122, and by being welded and fixed, nothing
The part for needing bolt, pin etc. that may loosen, good reliability, stability are strong；
3. support bar 121 is that layering is independently installed, helix tube screw-in is not needed, the assembly of once through steam generator is reduced
Difficulty, while tube spacing is further reduced, so that once through steam generator is more compact.121 upper limit position groove of support bar with should
The spacing of an adjacent support bar is adjustable, is easily installed；The top and bottom linkage section of support bar 121 has been reserved adjustable
Space, can be adjusted in the vertical direction, reduce installation difficulty；
4. limiting slot of the present invention using support bar 121 as the component for limiting helix tube Flow vibration, on support bar 121
1213 and the plane of the adjacent supports other side helix tube can be positioned, and pass through fixing piece 122,121 and of support bar
Heat-transfer pipe 20 is using being fastenedly connected, so that relative displacement can not occur between heat-transfer pipe 20 and support bar 121 to reduce heat transfer
20 surface scratching of pipe；
5. multiple support bars 121 can be arranged on 11 circumferencial direction of sleeve according to the number of plies of helix tube in the present invention, guarantee
Every layer of helix tube can be fixed by stablizing.
The present invention also constructs a kind of steam generator comprising heat transfer tube support device 10 and setting of the invention is at this
Heat-transfer pipe 20 in tube support device 10 of conducting heat.The heat transfer tube support device 10 illustrated in embodiment 1 and embodiment 2, herein
It repeats no more.The heat-transfer pipe 20 can be helix tube, can be mutually arranged and be formed by one or more layers helix tube.The helix tube
The threaded hole led in being equipped with, the threaded hole are centrally formed axle center.The support bar of the heat transfer tube support device 10 can be from the spiral
Hole is protruded into, and every layer of clamp for spiral pipe is located between two support bars, and the pipeline section correspondence of every layer of helix tube is fastened on support bar
On limiting slot on to realizing stable fixation.The steam generator uses heat transfer tube support device of the invention, to mention
The mounting stability of the high heat-transfer pipe.
