Specific embodiment
Figure is please referred to, the utility model provides a kind of boiler water wall scaffold.
The scaffold includes bearing bracket, section of ladder and scaffold board 3.
The bearing bracket includes crossbeam 11, cant beam 12 and fixed structure.
The crossbeam 11 is horizontally disposed, and the cant beam 12 is obliquely installed in below the crossbeam, is played a supportive role to crossbeam 11.
On the crossbeam 11 and the setting of cant beam 12 and same vertical plane.
For saving manufacturing cost and guaranteeing the purpose of structural strength, the crossbeam 11 and cant beam 12 are all made of channel steel system
At, and the higher one end of cant beam 12 is fixed on the lower section of crossbeam 11.
In the present embodiment, the crossbeam 11 and cant beam 12 are fixedly connected by welding, and commissure is fully welded to guarantee to connect
Connect the structural strength at place.
It is equipped with fixed structure in the lower end of cant beam 12 and crossbeam one end in the same direction, for bearing bracket to be fixed on pot
On furnace water-cooling wall 4.
In the present embodiment, the fixed structure includes two panels fixed plate 13, and two panels fixed plate 13 is respectively arranged on water-cooling wall 4
Two sides, and by being connected and fixed through the fixing bolt of 4 fin of water-cooling wall.
In the fixed structure in two panels fixed plate 13 it is a piece of by welding with 11 phase of cant beam 12 or crossbeam
Even, and commissure is fully welded the structural strength to guarantee junction.
It is noted that the utility model is not specifically limited the concrete form of fixed structure, this field skill
Art personnel can according to the actual situation with need to select suitable fixed structure.But equally should also be as it is considered, for making
With rear easy-to-dismount purpose, the fixed structure should be fixed on water-cooling wall by bolt or screw.
The section of ladder includes two isometric terraced beams 21 disposed in parallel, be equipped between two terraced beams 21 several it is mutually equal
Row, and perpendicular to the section of ladder cross-arm 22 of terraced beam setting.For purpose convenient to use, in the present embodiment, the same section of ladder
It is equidistant between two adjacent section of ladder cross-arms 22.
For the considerations of guaranteeing section of ladder structural strength, the ladder beam 21 is made of equal leg angle, the section of ladder cross-arm 22
It is made of round steel, terraced beam 21 passes through with each section of ladder cross-arm 22 to be welded and fixed, and weld is fully welded.
In order to be hooked on section of ladder on the crossbeam 1 and higher level's section of ladder of bearing bracket, in the same of two terraced beams 21
End is provided with the identical hook 23 of opening direction.
The scaffold board 3 is set on the section of ladder cross-arm 22 of section of ladder and fixed.
Boiler water wall scaffold provided by the utility model when in use, is needed using power drill in water-cooling wall fin
Then aperture on position installs bearing bracket by fixed structure in the position of aperture.
The size of working face as needed installs multiple bearing brackets in the same horizontal line of boiler water wall.
Section of ladder is hooked on the crossbeam of bearing bracket by hook and binds the soundness because guaranteeing its connection.
Further, it is selected that more ladders are further arranged in a manner of hook in the lower section of higher level's section of ladder according to the height of work surface
Section similarly carries out binding and reinforces to guarantee the soundness connected.
On the section of ladder cross-arm that scaffold board is ridden upon to the section of ladder hooked below two bearing brackets being disposed adjacent, and pass through
Binding is fixed.
