Description
Technical field
The invention belongs to boiler maintenance technical fields, and in particular to one kind is for boiler maintenance ash mouth support platform and builds
Method.
Background technique
Currently, the maintenance of China overwhelming majority heat power plant boiler burner hearth is all made of boiler hearth overhauling platform.Conventional
Inspection platform mostly uses scaffolding steel pipe to be built layer by layer, is then being laid with bamboo raft or stationary grid formation operation horizontal above
Face, operator moves back and forth between different work surfaces to overhaul.Boiler hearth overhauling platform has easy to use, safety
The features such as property is high.
It is very easy in the service work face that the outside of boiler is built using scaffold, and if to be carried out to boiler furnace
Maintenance, then overhauled by building scaffold it is then cumbersome, since people or object disengaging boiler will be by diameters about
The manhole of 450MM transmits, and transports several tons even tens of tons of scaffolding steel pipe and enters in furnace, then building steel pipe one by one
With connect, build several meters even the high hanging working faces of tens of rice, in boiler it is narrow closing, illumination is bad and has more
In the environment of prominent sharp portion, this building is time-consuming, laborious and dangerous work, and careless slightly, scaffolding steel pipe falls
Or water-cooling wall or other devices in touching boiler, the damage of device in boiler or water-cooling wall just face wear-and corrosion-resistant will be may cause
Protective layer is damaged, and operator may cause grievous injury as fallen accidentally.
It is overhauled under environment in such boiler, the scaffold inspection platform for building 600 sides or so cube generally requires 2 days
Time, and dismounting also at least needs one day time, and the every blowing out of boiler one day, biggish economy can be all caused to manufacturer
Loss；Also, the price for asking construction brigade to build scaffolding steel pipe is equally high.
After the completion of scaffold inspection platform is built, operator moves back and forth in different operational levels carries out maintenance behaviour
Make, it is dangerous and inconvenient, due to scaffolding steel pipe block, also will affect spraying abrasion-proof layer, the defect repair welding of service personnel
Deng operation；It is mobile in working face because usually having the gap and being uneven between the bamboo raft or screen that are laid on working face
Large-scale or compared with heavy equipment when, has no idea smoothly to be moved or be easy to above to be stuck, and operator is when moving above
It is also possible to be tripped.
In addition, when building boiler maintenance ash mouth support platform using scaffold, not due to boiler maintenance ash mouth normally shape
Rule, it is difficult to smoothly build biggish support platform, if lime-ash is accumulated, boiler maintenance ash mouth support platform but will be increased and built
Difficulty.
In view of this, it is necessary to propose that a kind of structure is simple, build rapid, adaptability and safety is good and be examined for boiler
Repair grey mouth support platform.
Summary of the invention
The object of the present invention is to provide a kind of structures simply, builds the boiler maintenance ash mouth that is used for rapid, at low cost supports
Platform.
It is a further object to provide a kind of included clamp device, safety is good, builds material access manhole side
Just be used for boiler maintenance ash mouth support platform and building method.
In order to solve the above-mentioned technical problem, the invention discloses a kind of boiler maintenance ash mouth support platform, the support is flat
Platform is built by several support frames；Support frame as described above includes two vertical poles and several cross bars for being fixedly welded between two vertical poles；

Support frame as described above is equipped with fixation hole and hold-down bars, and the fixation hole includes coaxial limiting section and fixed part, fixed part
Under limiting section, and the diameter of fixed part is less than limiting section, and the fixed part is equipped with internal screw thread；
Described hold-down bars one end and support frame are hinged, and the other end is equipped with spherical or cylindrical boss, are equipped with through-hole in the middle part of the boss,
Fastening bolt is equipped in through-hole, the through-hole and fastening bolt are threadedly coupled, and the boss diameter matches with the limiting section,
The fixed part diameter matches with fastening bolt.
Preferably, the hold-down bars is connected and fixed by fastening bolt and the fixation hole on adjacent supports frame.
Preferably, adjacent two support frame is in 90 ° of angles.
Preferably, support frame as described above width is less than the diameter of boiler manhole.
Preferably, the support platform maximum can bear 250kg/m2Pressure.
Preferably, the every 50-200m of support frame as described above chain is one section.
A kind of building method of boiler maintenance ash mouth support platform, enters boiler from manhole by service personnel, then will branch
Support chain is continuously introduced into boiler from manhole, according to space structure in boiler by support frame chain fold be combined into it is several be connected, on
The square shaped cells of lower stacking, and the hold-down bars on each support frame is passed through into fastening bolt and consolidating on adjacent supports frame respectively
Determine hole to be connected and fixed；To be built into the support platform being spliced by several square shaped cells, at the top of support platform
Set up protective net or railing.
Preferably, height and length when the support platform is built need with pot furnace inner space or maintenance and are changed.
Preferably, it when support frame chain being sent into boiler from manhole, to avoid damage to manhole, adds and protects in manhole surrounding
Support frame chain is sequentially sent in boiler again after sheath.
It preferably, first will be convex when hold-down bars being connected and fixed by the fixation hole in fastening bolt and adjacent supports frame
Platform is docked with the limiting section in fixation hole, then by fastening bolt precession fixed part to install fixation.
Of the invention is used for boiler maintenance ash mouth support platform and building method, has at least the following advantages:
1. by the fold combination of support frame chain, composed structure is simple, has higher support strength, can not be advised in flexible adaptation boiler
The then boiler maintenance ash mouth support platform in space, the support platform globality built is strong, and safety is preferable.
2. support frame chain etc., which builds material, can easily pass in and out boiler manhole, reduce the material transportation time, and material
Conveying and build or dismantling to carry out simultaneously.
3. when building by hold-down bars can fixation hole be connected and fixed rapidly, only need to be by fastening bolt and fixation hole point when disassembly
From it is convenient and rapid to build, and compared with building scaffold inspection platform, holistic conformation and dismounting time are greatly shortened.
4. hold-down bars is connected with support frame, compared with building scaffold inspection platform, reduce fastener carrying, location and installation
Trouble, and prevented part and fallen the possibility hurted sb.'s feelings, increased safety coefficient, kept installation more convenient rapidly.
5. fixation hole includes limiting section and fixed part, limiting section can make the rapid alignment and fixation hole of the boss of hold-down bars, side
Fastening bolt be tightened, when disassembly, fastening bolt need to only be made to be detached from fixed part, without by fastening bolt completely from
It is removed on boss, facilitates disassembly and installation next time.
6. by portable manually or electrically tool, the installation that hold-down bars can be rapidly completed in one or double cooperation is fixed.
