Abstract
Large-section rectangle smoke wind pipe fixed support, is characterized in that: the horizontal reinforcement ribs extending smoke wind pipe both sides downwards, as support bracket fastened support, arranges axial limiting baffle plate at the axial direction of smoke wind pipe; Horizontal reinforcement ribs position of center line bottom smoke wind pipe vertically to arrange with the shaped steel of horizontal reinforcement ribs same specification as support, arranges radial postive stop baffle in the radial direction of smoke wind pipe.The utility model had both met axial displacement and the radial displacement of restriction conduit entirety, met again the object of pipeline due to the radial displacement of the caused pipeline that expands with heat and contract with cold itself itself; Eliminate the thermal stress impact that radial thermal walking that pipeline itself brings owing to expanding with heat and contract with cold brings, solve the excessive problem causing support destroyed of common fixed support thermal stress.
Description
Technical field
The utility model belongs to boiler or kiln affiliated facility, is a kind of large-section rectangle smoke wind pipe fixed support.
Background technique
Along with the maximization of station boiler, the corresponding increase in smoke wind pipe cross section of boiler, pipeline internal pressure thrust increases.According to existing " thermal power plant cigarette wind pulverized coal channel Hanger Design handbook ", common fixed support manufacture is that smoke wind pipe bottom surface reinforcing rib and civil engineering pre-embedded steel slab are carried out full weld substantially, thus the displacement that restriction conduit is axial and radial.Due to smoke wind pipe in working order under can expand with heat and contract with cold, there is thermal walking in the radial direction in smoke wind pipe cross section itself.Along with the maximization of boiler, the cross section of smoke wind pipe becomes large, and the radial displacement of pipeline section itself is also large in change.If pipeline bottom surface reinforcing rib and civil engineering pre-embedded steel slab are carried out full weld according to common fixed support manufacture, restriction smoke wind pipe cross section is due to the radial displacement produced of expanding with heat and contract with cold, and thermal stress cannot be eliminated, thus can destroy support bracket fastened structure.
Model utility content
The utility model aims to provide a kind of large-section rectangle smoke wind pipe fixed support overcoming above-mentioned prior art deficiency, to solve the limited problem of pipeline section radial displacement.
The technological scheme of model utility: large-section rectangle smoke wind pipe fixed support, the horizontal reinforcement ribs extending smoke wind pipe both sides downwards, as support bracket fastened support, arranges axial limiting baffle plate at the axial direction of smoke wind pipe; Horizontal reinforcement ribs position of center line bottom smoke wind pipe vertically to arrange with the shaped steel of horizontal reinforcement ribs same specification as support, arranges radial postive stop baffle in the radial direction of smoke wind pipe.
Bottom support shaped steel, billet and polyfluortetraethylene plate are set; Arrange two pieces of billets and two pieces of polyfluortetraethylene plates bottom horizontal reinforcement ribs and between supporting surface, billet welds with horizontal reinforcement ribs, and polyfluortetraethylene plate is placed between billet.
First postive stop baffle and the gap S=2 ~ 3mm supported between shaped steel.
The utility model running principle is as follows: because smoke wind pipe bottom transverse reinforcing rib position of center line is provided with radial postive stop baffle, can the radial displacement of restriction conduit entirety.Axial limiting baffle plate is provided with in duct bottom horizontal reinforcement ribs position of center line both sides, can the axial displacement of restriction conduit entirety, but the radial displacement of this postive stop baffle not restriction conduit itself, meets the object of the radial displacement due to the caused smoke wind pipe itself that expands with heat and contract with cold.
Therefore the utility model has the advantages that: according to the roadability of smoke wind pipe, in the transverse direction of smoke wind pipe and radial both direction, postive stop baffle is set, on the basis of the displacement of restriction smoke wind pipe entirety, eliminate the thermal stress impact that the radial thermal walking that causes owing to expanding with heat and contract with cold brings, solve the excessive problem causing support destroyed of common fixed support thermal stress.The manufacture of this support is simple, quick and easy for installation, and reliability is high.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, large-section smoke wind pipe fixed support by supporting floor 1, polyfluortetraethylene plate 2, billet 3, support shaped steel 4, first postive stop baffle 5, second postive stop baffle 6, axial limiting baffle plate 7, radial postive stop baffle 8, horizontal reinforcement ribs 9 form.The horizontal reinforcement ribs 9 of downward prolongation smoke wind pipe both sides, as support bracket fastened support, arranges axial limiting baffle plate 7 at the axial direction of smoke wind pipe 10; Horizontal reinforcement ribs 9 position of center line bottom smoke wind pipe 10 vertically to arrange with the shaped steel of horizontal reinforcement ribs 9 same specification as support, arranges radial postive stop baffle 8 in the radial direction of smoke wind pipe 10.
Bottom support shaped steel 4, billet 3 and polyfluortetraethylene plate 2 are set; Bottom horizontal reinforcement ribs 9 and between supporting surface, arrange two pieces of billets 3 and two pieces of polyfluortetraethylene plates 2, billet 3 welds with horizontal reinforcement ribs 9, and polyfluortetraethylene plate 2 is placed between billet 3.
First postive stop baffle and the gap S=2 ~ 3mm supported between shaped steel.
When smoke wind pipe 10 is prefabricated, horizontal reinforcement ribs 9 lower weld in smoke wind pipe 10 central position supports shaped steel 4 and billet 3; Lengthen the horizontal reinforcement ribs 9 of pipeline both sides as pipeline support, and weld support floor 1 and billet 3.Need the both sides of the heart in the duct to install additional and support shaped steel 4, support floor 1 and billet 3 according to actual conditions.Before smoke wind pipe 10 lifts, the embedded part of civil engineering welds billet 3, first postive stop baffle 5 and the second postive stop baffle 6.The setting direction of the first postive stop baffle 5 and the second postive stop baffle 6 should be noted during installation, the postive stop baffle of smoke wind pipe 10 central position be radial postive stop baffle 8(as shown in Figure 5, Figure 6), remaining postive stop baffle be axial limiting baffle plate 7(as shown in figs. 2 to 4), retention gap S=2 ~ 3mm between the first postive stop baffle 5 and billet 3.After all welding jobs complete, two pieces of polyfluortetraethylene plates 2 placed by the billet 3 of civil engineering embedded part upper weld.Finally the lifting of prefabricated smoke wind pipe 10 is put in place.
Determine after the specification of the shaped steel of horizontal reinforcement ribs 9 and size need calculate according to factors such as support bracket fastened stressed size and smoke wind pipe sectional dimensions, the axial displacement of axial limiting baffle plate 7 restriction conduit, its size is determined after need calculating according to the size of the end thrust of pipeline, the axial displacement of radial postive stop baffle 8 restriction conduit that duct bottom horizontal reinforcement ribs position of center line is arranged, its size is determined after need calculating according to the size to thrust of pipeline.
