1. the operation principle of carrier pile penetration automatic measuring instrument mainly calculates hoist engine on carrier pile piling machine
The length of steel wire rope, its calculation formula are：L=α * C*N
In formula, L：Rope capacity；
α：The regulation coefficient of hoist engine roller bearing girth；(considering influence of the steel wire rope of windlass thickness to roller bearing girth)
Calculated according to the parameter alpha value of certain piling hoist engine as follows：(this value is applicable to the roller bearing of hoist engine different-diameter)
1) drive piles hoist engine roller bearing a diameter of 400mm when
2) the capabilities length individual layer 30m of steel wire rope of windlass (along roller bearing around a circle)
3) the diameter 22mm of steel wire rope
4) the diameter actual diameter that steel wire rope is considered when constructing is 422mm (steel wire rope center line)
5) roller bearing girth differs 422 × 3.14-400 × 3.14=69.08mm with the girth of practice of construction
6) girth difference and 69.08/400 × 3.14=0.055 of percentage of the girth of roller bearing
7) then α values take 1+0.055=1.055 in the calculation formula of rope capacity
C：The girth of hoist engine roller bearing；
N：Encoder reads the number of turns of hoist engine roller bearing device.
2. the penetration of carrier pile is what is come out by calculating the mathematic interpolation of steel wire rope of windlass, its computational methods
It is as follows：
1)
First hits the length of preceding steel wire rope：L0=α * C*N0(N0The number of turns of roller bearing when hitting preceding i.e. steel wire rope looseness for first)
First hits the length of rear steel wire rope：L1=α * C*N1(N1For first number of turns for hitting rear roller bearing)
Second hits the length of rear steel wire rope：L2=α * C*N2(N2For second number of turns for hitting rear roller bearing)
3rd hits the length of rear steel wire rope：L3=α * C*N3(N3For the 3rd number of turns for hitting rear roller bearing)
2)
First hits the length difference of rear steel wire rope：X1=L1-L0(first hits pile penetration)
Second hits the length difference of rear steel wire rope：X2=L2-L1(second hits pile penetration)
3rd hits the length difference of rear steel wire rope：X3=L3-L2(penetration)
3)
Penetration and (total value settled three times) be：X=X1+X2+X3
Such as X values≤design drawing or carrier pile specification setting, to regard carrier construction quality qualified, such as X value ＞ design drawing laterals
It is unqualified that definite value or carrier pile specification setting are then considered as carrier construction quality, piling worker the carrier will be continued plus
Work and processing.
4)
Provided further accordance with carrier pile specification, carrier pile three, which hits to pass through respectively to sink to drop, will also meet X1≥X2≥X3, cannot such as meet
Above-mentioned regulation, then it is unqualified to be considered as carrier.
Calculation formula and related data above will be incorporated into calculation procedure.
