Hook 3211 is connect with hangers 251, so that spiral supporting leg 3 is detached from ground, at this point, push frame body 2 mobile again, and spiral supporting leg 3
It is moved together with frame body 2, individually holds the movement of spiral supporting leg 3 without separately setting worker, save manpower, it is easy to operate.
Specific work process: the mobile platform is lifted on tank body 1 to be onstructed, and traveling wheel 23 is made to be undertaken on tank body
On 1 wind girder, and directive wheel 24 is contacted with the basic ring beam 13 of 1 bottom of tank body, plays 2 horizontal direction active force of balance frame
Purpose, make spiral supporting leg 3 and ground face contact, and fasten spiral supporting leg 3, finally track card 41 is connected on wind girder, and
The left and right sides of traveling wheel 23 is respectively provided with track card 41, and then rotation abuts stud 4231, so that abutting stud 4231 and wind resistance
Circle pushes against, and prevents traveling wheel 23 from freely rolling, and construction personnel station carries out construction operation on construction plate 21.
When needing to construct to other positions of tank body 1, the personnel on ground loosen spiral supporting leg 3, and on wind girder
Personnel it is synchronous push frame body 2 to arrive suitable position, then by 4 fixing bracket body of limit assembly, 2 position, and fasten spiral supporting leg 3, i.e.,
It can construct；It is easy to use, improve construction efficiency.
When construction, on a tank body 1, two or four mobile operation platforms can be carried out simultaneously and are constructed, but are wanted
Dispersion installation, avoids wind girder stress from excessively concentrating.
In terms of duration angle, a tank double-pole scaffold probably need it is steel pipe 2,000 6 meters long, it is 1,000 4 meters long, 1.5
Rice is 2000 long, fastener 15000,2000 pieces of springboard, sets up with 10 people of scaffolder, 15 people of power work, to set up 10 days, wherein material
The preparation and transport of material take 7 days time, and adding up to the duration is 17 days.And a tank prepares 2 with 4 movement operation platform materials
It, makes 4 people of welder, and 3 people of power work need to only make 5 days, and adding up to the duration is 7 days.From above data, we are not difficult to find out movement
Operation platform is economical and can shorten the construction period.
It economically sees, a tank double-pole scaffold frame material lease expenses is about 50,000 yuan/month, sets up and demolition expense
With being 100,000 yuan, 10,000 yuan of freight, and frame material will reserve deposit, while long in time limit cannot timely have enough to meet the need.And one
The expense of mobile operation platform is probably at 30,000 yuan or so, and four are 120,000, therefore mobile operation platform is more economical.
Embodiment two:
A kind of fire-fighting construction moving platform construction method, comprising the following steps:
S1, the mobile platform is transported to construction site, and is lifted to the second wind girder of tank body 1, lifted
Journey need to use slip rope, with prevent frame body 2 rotate；
After S2, lifting are in place, 2 position of frame body is limited by limit assembly 4, prevents frame body 2 from arbitrarily sliding, and directive wheel 24 supports
On basic ring beam 13, spiral supporting leg 3 is adjusted, keeps spiral supporting leg 3 and ground face contact secured；
S3, construction personnel, which are climbed up, carries out construction operation on the construction plate 21 of frame body 2；
S4, when needing movable support body 2, on second wind girder be equipped with guardian, guardian open limit assembly 4, ground
Operator loosen spiral supporting leg 3, it is synchronous that frame body 2 is pushed to arrive suitable position, then by 4 fixing bracket body of limit assembly, 2 position,
And spiral supporting leg 3 is fastened, it can construct after passed examination.
The embodiment of present embodiment is presently preferred embodiments of the present invention, not limits protection of the invention according to this
Range, therefore: the equivalence changes that all structures under this invention, shape, principle are done, should all be covered by protection scope of the present invention it
It is interior.
