Description
Technical field
The present invention relates to power station service technique fields, and in particular to the removable maintenance in surface low road is flat in a kind of power station
Platform.
Background technology
For the power station holes Zhong Biao and stilling pond flow-passing surface, existing maintenance solution is to set up console mode maintenance framed bent, this
Although scheme can achieve the purpose that maintenance, there is many flaws：
1. console mode maintenance framed bent area is excessive, is encountered during setting up and much be unfavorable for setting up and increasing setting up risk
Problem, need highly precisely organizing ability carry out flood season after overhaul；
2. work consuming is time-consuming：Single middle table hole sets up console mode framed bent and needs steel pipe 25.4t, sets up（It removes）Period is long, ten works
People just needs 10 day time in the horizontal plane, and still more flow-passing surface has certain angle of inclination, and particularly notably, Burner zone inclines
Rake angle is up to 51.34 °, therefore danger is very high, this process steel pipe landing etc. can also damage flow-passing surface；
2. table hole flow-passing surface angle of inclination is big in, and each upright bar needs special pedestal just to can guarantee not glide, broken to flow-passing surface
Bad possibility is very high；
3. vertical flow-passing surface elevation location is different, of different size, flow-passing surface is of different size, and the console mode of plurality of specifications is needed to arrange
Frame could meet actual requirement, increase cost, for different elevations, if using the console mode framed bent of same size, fall
Ground formula framed bent size may be bigger than normal or less than normal, when framed bent size is bigger than normal, then can not set up, when platform size is less than normal, then its
Periphery and flow-passing surface can not ensure safety apart from larger.
In view of this, our company voluntarily has developed a kind of inspection platform, do not have with many console modes maintenance framed bent
Advantage.
