Abstract
The invention relates to a suspension structure of a pendent tube used for an S-shaped tube panel. The invention is characterized in that the suspension structure comprises two tube clamps buckled on the tube panel oppositely; a steel plate is inserted in each tube clamp; the two sides of the tube clamp are respectively provided with one pendent tube; and a supporting steel plate used for supporting the tube panel is horizontally arranged on the pendent tube. The suspension structure has the advantages that due to the simple structure, the pendent tube is processed and installed more conveniently; the number of the tube clamp can be increased or decreased according to the actual situation, thereby effectively preventing the tube clamps from leaving the rank; and whether the space between tubes in the tube panel is regular or not, the tube panel can be suspended on the pendent tube by adjusting the stressed point by the tube clamps in different specifications.
Description
Technical field
The present invention relates to a kind of overhung construction, be used to reduce the swing of tube panel and transmit horizontal tube weight.
Background technology
The flue gas stream of fluctuation washes away tube panel and produces swing, and the tube panel of swing disturbs flue gas stream again, and constantly from flue gas stream, absorbs energy, so the swing of tube panel is difficult to stop.This swing of tube panel can cause that the fixedly root of tube panel produces the bending stress of alternation, causes fatigue rupture, also possibly collide each other to cause wear-out failure; The fluctuation of flue gas also can make the part pipe in the tube panel fall out on the other hand, produces wear-out failure or local overheating.Need to adopt certain overhung construction.Simultaneously for the pipe safe operation, horizontal tube weight need be taked certain lifting mode safe transfer according to the design feature of self hot side.The column pipe overhung construction just belongs to a kind of of above-mentioned lifting mode.
Conventional overhung construction is as shown in Figure 1, comprises zigzag tray 3, zigzag tray 3 and column pipe 1 welding, and little steel plate 4 welds with zigzag tray 3 mutually, and it is that 2 gravity passes on the column pipe 1 through zigzag tray 3 that such structure can make horizontal tube.The welding of little steel plate 4 and zigzag tray 3 has limited the upper and lower displacement of horizontal tube, plays positioning action, but horizontal piping 2 of while is along its axially free wxpansion.
Though this structure compact conformation because 3 retrofits of zigzag tray are difficult, causes difficult installation, is prone to stay hidden danger, horizontal piping 2 pipes that possibly cause being in operation are fallen out.Secondly, this structure is limited by zigzag tray 3 can only be used for horizontal piping 2 between the upper and lower apart from being equal to, and in the snake-like tube row that spacing can not be too little, for the less horizontal tube panel of spacing, it can't be suitable for.
Summary of the invention
The overhung construction that the purpose of this invention is to provide a kind of simple installation and suitable any spacing.
In order to achieve the above object; Technical scheme of the present invention has provided a kind of column pipe overhung construction that is used for S-shaped tube panel; It is characterized in that, comprise two, in pipe clamp, be inserted with steel plate being buckled in the pipe clamp on the tube panel; On tube panel, be provided with 2 column pipes at least, level is provided with the supporting steel plate that is used to support tube panel on column pipe.
Further, said two inequality to the width that is buckled in the pipe clamp on the tube panel.
Level is provided with the supporting steel plate that is used to support tube panel on the column pipe.
The steel plate that in pipe clamp, is inserted with is the comb shape steel plate, is convenient to match with pipe clamp, be convenient to assembling, and the comb shape partial-length x of steel plate is not more than the width of pipe clamp.
On the tube panel of pipe clamp both sides, be provided with the location bloom, tube panel at least respectively has one group of location bloom up and down, and every group has 2 location blooms about at least, and 2 positions are apart from pipe clamp center line symmetry, and location bloom (10) apart from the tube panel center symmetry.
Overhung construction provided by the invention is fairly simple, has brought the very big free degree for the design of tube panel.Can be used for effectively preventing that pipe from falling out through adding pipe clamp such as the long words of: tube panel horizontal segment, in any case pipe can support through the position of the supporting steel plate on the adjustment column pipe apart from changing between the upper and lower, in addition processing with install all more convenient.
Advantage of the present invention is: column pipe is simple in structure, and processing is all more convenient with installation; Pipe clamp can require add or reduce according to actual conditions, can prevent effectively that pipe from falling out; No matter in the tube panel pipe way apart from whether rule, can adjust stress point through the different pipe clamp of specification, and hang on the column pipe.

Embodiment
The invention provides a kind of column pipe overhung construction that is used for S-shaped tube panel, the form through column pipe+pipe clamp realizes.As Fig. 3 and shown in Figure 4 be the sketch map of pipe clamp part, Fig. 5 be a column pipe sketch map partly.Below in conjunction with Fig. 2 to Fig. 5 the present invention is described; Comprise two to being buckled in the pipe clamp 8 on the tube panel 5; Inequality being convenient to of the width of two pipe clamps 8 welded; In pipe clamp 8, be inserted with steel plate 9, be respectively equipped with a column pipe 6 in the both sides of pipe clamp 8, level is provided with the supporting steel plate 7 that is used to support tube panel 5 on column pipe 6.
6 of column pipes play transmission tube panel 5 gravity, and weight is transmitted through supporting steel plate 7, and 8 of pipe clamps that are installed on the tube panel play tube panel 5 fixations, and steel plate 9 inserts pipe clamp 8, guarantees two tube pitch up and down.
The steel plate 9 that in pipe clamp 8, is inserted with is the comb shape steel plate, is convenient to match with pipe clamp, is convenient to assembling, and as shown in Figure 6, and the comb shape partial-length x of steel plate 9 is not more than the width of pipe clamp 8.
As shown in Figure 7; On the tube panel 5 of pipe clamp 8 both sides, be provided with location bloom 10, tube panel 5 at least respectively has one group of location bloom 10 up and down, and every group has 2 location blooms 10 about at least; And 2 positions are apart from pipe clamp 8 center lines symmetry, and location bloom 10 is symmetrical apart from tube panel 5 centers.
Level is provided with the supporting steel plate 7 that is used to support tube panel 5 on the column pipe 6; Can change the distance between any two supporting steel plates 7; Can add or reduce the quantity of supporting steel plate 7 arbitrarily; So that be used for cooperating the S-shaped tube panel of different size, this is especially convenient for irregular S-shaped tube panel or the smaller S-shaped tube panel of pipe way distance.
