Description

A kind of component and method for repairing boiler crackle
Technical field
The present invention relates to Maintenance of Boiler technical field, particularly a kind of component and method for repairing boiler crackle.
Background technology
Boiler used is with coal as fuel in well-known thermal power plant, using being absorbed to heat in combustion chamber Metal vapour pipe road outward supplying heat, thus passed through on the furnace roof of body of heater and furnace wall and be provided with numerous metal vapour pipe roads.Due to These metal vapour pipe roads can constantly occur relative shift the reason for during boiler works because expanding with heat and contract with cold, thus in gold During category steam Pipe installing gap is left and between hole wall.When being worked in order to avoid boiler inner clamps with cigarette ash high-temperature flue gas Incessantly by gap to external diffusion under the influence of boiler inside and outside differential pressure, triggering reduces boiler energy consumption, pollution surrounding environment And the adverse consequences such as furnace roof dust stratification amount are reduced, therefore seal approach must be taken to these gaps, to ensure the reliably working of boiler. But in practice, it has been found that due to the random relative displacement in metal vapour pipe road, the gap between pipeline and hole wall can constantly occur Change, or even extruding hole wall, cause hole wall to ftracture, crack on the body of heater around hole.And this crackle is bound to once producing After can quickly take advantage of a situation extension, more and more long, increasing, the sealing property of boiler will necessarily be influenceed, so as to influence boiler just Often work.At present in terms of the reparation of boiler crackle, general use carries out high-temperature heating to the metal surface around crackle, is allowed to Fusing is integrated, the electric welding method for repairing and mending to eliminate crackle, there is certain effect, but because the sphere of action of welding operation is limited, And full armrest control operation, therefore surface reconditioning is essentially limited to, for the more difficult control of thorough degree that body of heater depths crackle is eliminated, Thus cause repairing quality to be relatively difficult to ensure card, still suffer from the hidden danger that crackle is further expanded.
The content of the invention
The invention aims to overcome repairing quality existing in terms of boiler of power plant crack forming mechanism to be at present relatively difficult to ensure The weak point of card, there is provided a kind of method is simple and science, the component of reparation boiler crackle easy to implement and quality controllable and Method.
The component for repairing boiler crackle of the invention, is characterised by being entered by with self tapping, the spacing and multiple clamping of retaining Spacing, traction surrounding wall body function reparation bolt is filled the post of, and the main body for repairing bolt is made up of shank of bolt and bolt head, wherein: Pawl shape retaining screw thread is provided with described shank of bolt;At least be provided with two circles and split shape comprising being provided with described bolt head The spacing dogging shoulder and upper band of latch transfinite and understand the control screw head of the thin neck that fall from dynamic circuit breaker.
A kind of method for repairing boiler crackle of the invention, is characterised by using spacing and many with self tapping entrance, retaining Heavy truck is held spacing, traction surrounding wall body function, main body and the shank of bolt of pawl shape retaining screw thread is provided with from above and comprising being provided with At least be provided with two circles split shape latch spacing dogging shoulder and upper band transfinite can from dynamic circuit breaker fall thin neck control screw head bolt head structure Into the reparation component filled the post of of reparation bolt, to be superimposed repair crack in the way of alternately dislocation is sewed and mend, construction procedure is as follows:
First in the two ends Ge Zuanyi holes of crackle, and judge the depth and width of crackle accordingly, then selection and screw in specification respectively It is suitable to repair bolt;
Drilled successively with the spacing of 1.4-1.9 times of spacing dogging shoulder diameter on crackle and screw in described reparation respectively successively Bolt;
Drill and screw in described reparation bolt on the crackle between each reparation bolt again again;
Finally make outer surface planarizing process on demand.
The present invention based on above-mentioned design repairs the component and method of boiler crackle, is employed on spacing dogging shoulder due to combining At least provided with two circles split the spacing latch of shape, with vertically to retaining is spacing and level to multiple clamping, draw spacing surrounding wall The reparation bolt of body function, and the method for repairing bolt is alternately shifted to install with darning formula on crackle, make boiler worked Trigger displacement and extrude hole wall, cause to pass through the crackle that hole is nearby produced on body of heater because metal vapour pipe road expands with heat and contract with cold in journey Can reliably be repaired by suitably repairing bolt from specification, boiler is effectively repaired, so that it is guaranteed that boiler The reliably working life-span, with prior art electric welding repair boiler crackle method compared with, hence it is evident that with methodological science and rationally, apply Work is convenient and repairing effect is good, low cost and other advantages, thus with significant technical advance, very good economy and extremely strong Practicality.
Brief description of the drawings
Fig. 1 is the structural representation of reparation bolt in the embodiment of the present invention;
Fig. 2 is the operating process schematic diagram of the embodiment of the present invention.
In figure:
1. the bolt head of 2. shank of bolt of bolt, 21. retaining screw thread 3. is repaired
31. spacing dogging shoulders 311. split the control thin neck of screw head 321. of shape latch 32.
4. the hole of crackle 41..
Specific embodiment
The invention will be further described with exemplary embodiments below in conjunction with the accompanying drawings.
In Fig. 1, the component for repairing boiler crackle of the invention is entered by with self tapping, the spacing and multiple clamping of retaining is limited Position, the reparation bolt 1 of traction surrounding wall body function are filled the post of, and the main body for repairing bolt 1 is made up of shank of bolt 2 and bolt head 3, its In:Pawl shape retaining screw thread 21 is provided with described shank of bolt 2;3 are at least provided with comprising being provided with described bolt head The spacing dogging shoulder 31 and upper band that two circles split shape latch 311 transfinite the control screw head 32 of thin neck 321 of falling from dynamic circuit breaker.
In fig. 1 and 2, a kind of method for repairing boiler crackle of the present invention, is characterised by using with self tapping entrance, only Move back the shank of bolt 2 that spacing spacing and multiple clamping, traction surrounding wall body function, main body are provided with pawl shape retaining screw thread 21 from above With transfinite and can fall thin neck 321 from dynamic circuit breaker comprising being provided with least to be provided with two circles and split the spacing dogging shoulder 31 and upper band of shape latch 311 Control screw head 32 the reparation component filled the post of of reparations bolt 1 that constitutes of bolt head 3, to be superimposed alternately dislocation darning in the way of repair Multiple crackle, construction procedure is as follows:
First in the two ends Ge Zuanyi holes 41 of crackle 4, and judge the depth and width of crackle accordingly, then select and screw in respectively and advise Lattice suitably repair bolt 1;
Drilled successively with the spacing of the 1.4-1.9 times of diameter of spacing dogging shoulder 31 on crackle 4 and 41 and screwed in respectively successively described Repair bolt 1;
Drill 41 and the described reparation bolt 1 of screw-in again on the crackle 4 between each reparation bolt 1 again;
Finally make outer surface planarizing process on demand.
