Description
Technical field
The present invention relates to boiler maintenance technical field, be specifically related to a kind of novel boiler maintenance ash mouth support platform, its support works face arranged at Boiler Ash mouth upper position when may be used for boiler of power plant maintenance, for boiler maintenance equipment provides the smooth scope of operation, the various repair apparatus of boiler both can be coordinated to use, also can be used alone; Excellent, boiler maintenance support platform arbitrarily can combine according to the length of boiler and reach scope of operation length requirement needed for boiler maintenance; The width that can also need according to the different type of furnace customizes.The safety of its equipment, convenience, agility and practicality all belong to original creation product of the same trade both at home and abroad.
Background technology
The working platform of existing boiler maintenance, be adopt scaffolding steel pipe to build layer by layer, be finally built into the scope of operation, the boiler maintenance then laying bamboo raft above supports the scope of operation.
Mainly there is following problem and shortcoming in it:
1, easily cause due to reasons in structure work plane to subside in whole or in part, there is higher personal safety and device security hidden danger.
2, the service work face effort using steel pipe scaffold to build: in closed container by diameter less than 500MM manhole transmission, transport the scaffolding of tens tons and build the scaffolding steel pipe of about 600 cubes and fastener enters in stove, one one steel pipe is built and couples together again, build the unsettled work plane more than 6-12 rice height, be one and consume one's strength very much and adventurous work.
3, the grey mouth working platform using steel pipe scaffold to build is consuming time: for 1,000,000 kilowatts of unit boilers, build and dismantle about 660 cubes scaffold steel pipe fastener ash the mouth scaffold support platform minimum needs time of about 3 days, not only effort and also time-consuming.
4, use the steel pipe scaffold grey mouth working platform cost of building too high: because of rising steadily of steel and cost of labor, make the expense that scaffolds erecting also very high, for 1,000,000 kilowatts of boilers, build a grey mouth and support more than scope of operation needs 150,000 RMB, and in the trend risen steadily.
5, the infringement to boiler inner wall in steel pipe scaffold material build process is used: the water caltrop cutting edge of a knife or a sword at steel pipe two ends is strict, because be direct contact with boiler inner wall, so be easy to cause damage to boiler water-wall tube when building.
Build with demolishing process in have unavoidably steel pipe and metal connecting piece falling from high altitude thing occur, not only easily personal injury is caused to field personnel, and the water-cooling wall of boiler and other boiler units are also easily caused damage, if reparation in time can cause heavy losses to power plant.
6, the grey mouth working platform using steel pipe scaffold to build has a lot of potential safety hazard to maintainer and repair apparatus:
1) when building, the work high above the ground risk of building personnel is inherently very large;
2) because the bearing plate at top is bamboo raft, so the weight capacity of veneer is very poor, often there will be the situation of aging bamboo raft fracture, people is easy to be leaked down; Due to top bamboo raft itself not straight in addition between steel pipe irregularity so bamboo raft work plane that top is laid has a lot of larger space (from tens centimeters to tens centimeters not etc.) between bamboo raft and bamboo raft, slightly little article are easy to drop down from gap, easily cause falling object from high altitude to there is very large potential safety hazard to staff below, also have because gap is excessive, out-of-flatness, people walk to be easy to fall in space above and cause personal injury.
3) often can there is the situation of overturning to repair apparatus (especially large-scale repair apparatus) when working mobile, very large potential safety hazard is all existed to the person of maintainer and repair apparatus safety.
7, (grey mouth working platform) the service work face equipment moving using steel pipe scaffold to build is very inconvenient: lay because its work plane is bamboo raft, be uneven, gap is very large, so have no idea when work plane moves large-scale or heavier equipment carry out smooth-going movement above or be easy to be stuck.
8, the grey mouth working platform maintenance using steel pipe scaffold to build is very inconvenient: if because the position contacted with scaffold needs to overhaul the position also needing to readjust scaffold in maintenance process, when the overall sandblasting carried out in stove sprays (when checking leak source in stove), the place contacted with boiler inner wall is needed to remove one by one, very inconvenient.In use, the muscle power consumed when maintainer climbs is very large, have no idea to carry overweight and large-scale repair apparatus for steel pipe scaffold, brings inconvenience to service work.
Summary of the invention
Described in background technology, in boiler maintenance process, there is above-mentioned middle problems and defect in existing mode of building boiler maintenance work plane, therefore steam power station be badly in need of that a safety, weight capacity are strong, surfacing, the product that easy to assemble, convenient transport can substitute the present boiler maintenance scope of operation.
The present invention is achieved through the following technical solutions:
