Telltale mark is provided with the respective distances of steel wire rope 6.Before the steel wire rope 6 is wound, according to the distance and volume of telltale mark to fag end
3 diameters of cylinder accurately calculate initial position of the cable wire end in the grooving of reel 3, and the fag end of steel wire rope 6 on cheese is untied,
Traction is to the initial position in the grooving of reel 3 and fixes temporarily.Rotating drum 3, when steel wire rope 6 is wound at telltale mark
When, just overlapped with the anchor point and pressing plate on reel 3, pressing plate is installed and positions the middle part of steel wire rope 6.Due to accurately calculating rope
The initial position of head, during winding, the telltale mark on steel wire rope 6 is just overlapped with the anchor point on reel 3, can avoid steel wire
The deviations of the winding of rope 6 are exceeded and repeat to do over again.Further, the anchor point is at about 92.5 meters away from the fag end of steel wire rope 6,
The middle of steel wire rope 6 is fixed on reel 3 with positioning pressuring plate, it is reliable solid in the middle part of the achievable body of reel 3 and steel wire rope 6
It is fixed, make the independent operating of every steel wire rope 6 that steel wire rope 6 is not likely to produce on play and rolling sliding, reel 3, do not interfere with each other, it is ensured that
The stability of lifting system.
Further, the cheese 7 and the alignment of reel 3, before steel wire rope 6 is installed, access the deadman's brake 5 of reel 3
Power supply；When steel wire rope 6 winds and transferred, deadman's brake 5 can put into braking at any time.Deadman's brake 5 is used for turning to reel 3
Dynamic and direction is controlled, it is ensured that the security of the device of reel 3.
After the plant-grid connection of deadman's brake 5, the steel wire rope 6 on cheese 7 is wound coiling 3 by rotating drum 3, continue to
Steel wire rope 6 is transferred in the side of ship reception chamber 8, is extremely connected with ship reception chamber 8；Further, fixing device, the steel of decentralization are provided with ship reception chamber 8
Cord 6 is connected with the regulation device set on ship reception chamber 8.It is to realize the connection of steel wire rope 6 and ship reception chamber 8 by this step.
Then the remaining steel wire rope 6 on cheese 7 is transferred to the side of floating drum 1 using bridge machine, it is and equal through after running block 2
Weighing apparatus oil cylinder 9 is connected.The present invention uses bridge machine disposably to transfer the remaining steel wire rope 6 on a cheese 7 to the side of floating drum 1, will
This root steel wire rope 6 is passed through after a grooving on the running block 2 at the top of floating drum 1, with the balanced oil cylinder 9 being located on fixed fine strain of millet seat
Connection.Then according to it is above-mentioned by root decentralization mounting means will on other three cheeses 7 residue steel wire rope 6 pass through running block respectively
Connected after grooving on 2 with the balanced oil cylinder 9 being located on fixed beam seat.In order to relative with four steel wire ropes 6 on four cheeses 7
Should, 4 groovings are provided with the running block 2.It is to realize the connection of steel wire rope 6 and floating drum 1 by this step.
After according to above-mentioned installation method by one group of lifting system installation, the reel 3 for having installed steel wire rope 6 is disengaged
Shaft coupling 11 and the deadman's brake 5 for putting into reel, repeat step 4) carry out other groups of reels 3 steel wire rope 6 install, until eight
Group lifting system is installed.After the steel wire rope 6 of full reel 3 is installed, interim auxiliary drive is pulled down, dress shaft coupling is returned
Device 11 is by reel 3 again shaft coupling.Because the unitary rotation inertia of reel 3 for having installed steel wire rope 6 is larger, and the two of steel wire rope 6
End is connected with ship reception chamber 8 and balanced oil cylinder 9, after one group of lifting system installation is completed, will install the volume of steel wire rope 6
Cylinder 3 disengages shaft coupling 11 and puts into the deadman's brake 5 of reel 3, and the reel 3 for having installed steel wire rope 6 can be made not to be rotated further by, keep
It is stable, disengage after shaft coupling 11, the steel wire rope 6 for being convenient for other unloaded reels 3 is installed.In eight groups of lifting system installations
Afterwards, interim auxiliary drive is pulled down, dress shaft coupling 11 is returned by reel 3 again shaft coupling, forms overall reel connecting shaft lifting
System.The interim auxiliary drive is only interim during installation to be provided driving force, solves major diameter drum 3 during installation
Unpowered technical barrier, can exit after lifting system installation and use, and turn to provide drive by floating drum and steel wire rope 6
Power.
It is to realize the connection of steel wire rope 6 and ship reception chamber 8 and floating drum 1 by above-mentioned steps, when by eight groups of reels 3 and steel wire rope
After 6 installations, fluctuated by floating drum 1 in vertical shaft, drive the side of ship reception chamber 8 to move up and down through steel wire rope 6, realized and rise ship
The lifting operation of machine lifting system.
One kind carries out lifting system installation accuracy control method using above-mentioned construction method, comprises the following steps：
1) after floating drum 1 is completed, floating drum 1 is sling and static, carry out floating drum 1 weigh and each group floating drum 1 between it is flat
Weigh counterweight, after checking that the perpendicularity of the full-height scope of floating drum 1 meets the requirements, by the axis-penetrating locking of floating drum 1 in Shaft bank；
2) when running block 2 is installed, adjustment each movable pulley center discrepancy in elevation and coaxiality deviation reach and are fixed after requirement；
3) the installation control line that measuring reel 3 and connecting shaft 4 are is in same measuring instrument, same measuring station, one
Secondary property completes measurement and positioning；
4) reel 3 is lifted in place using bridge machine, the strict control vertical, horizontal central axis of reel 3 and adjacent volume during adjustment
The 3 center discrepancy in elevation of cylinder, the axiality of 3 groups of reel, the reference for installation requirement for making it meet reel 3；Deadman's brake 5 and fluid pressure line
After connection, brake clearance is adjusted after carrying out pressure test, pass the test；
5) when connecting shaft 4 is assembled, the flange bolt for tightening up connecting shaft 4 and shaft coupling 11 again is first loosened, to reduce connecting shaft 4
Installation moment of torsion；
6) winding direction of steel wire rope 6 is consistent with the rotation direction of reel 3；After steel wire rope 6 is installed, floating drum 1 is unlocked, floated

Into measurement and positioning；
D) reel is lifted in place, strict control reel vertical, horizontal central axis and adjacent reel center during adjustment using bridge machine
The axiality of the discrepancy in elevation, reel group, the reference for installation requirement for making it meet reel；After deadman's brake is connected with fluid pressure line, enter
Brake clearance is adjusted after row pressure test, pass the test；
E) when connecting shaft is assembled, first loosen the flange bolt for tightening up connecting shaft and shaft coupling again, turned round with the installation for reducing connecting shaft
Square；
F) wirerope-winding direction is consistent with reel rotation direction；After steel wire rope is installed, floating drum is unlocked, floating drum is carried out and holds ship
There is water running in railway carriage or compartment, after after the abundant tensioning of steel wire rope, balanced oil cylinder is adjusted again, makes each steel wire rope uniform force.
G) after whole main lifting equipments and annex installation, carry out repetition measurement and inspect for acceptance and make a record.
