The one of which canoe of steel wire rope 4 is as shown in figure 1, this kind of canoe is realized in the support rope dolly of ship unloaders five
The operation stroke of forestock rope dolly will lead front side (extra large side) stroke quartering of main carriage 1, the operation stroke of butt rope dolly
Rear side (land side) stroke trisection of dolly 1, its embodiment is as follows, wherein assume main carriage 1 in the process of running from
It is L1 to open the distance of front side (extra large side) extension from home, and main carriage 1 leaves rear side (land side) backreach terminal in the process of running
Distance be L2.
Make to use 3 between the 3rd forestock rope dolly (nearest from main carriage) and main carriage 1：The assembly pulley winding of 4 multiplying powers,
The operating rate of i.e. the 3rd forestock rope dolly is the 3/4 of main carriage 1, and main carriage length of run is L1, then the 3rd forestock rope dolly
Range ability be 3L1/4；
Make to use 2 between second forestock rope dolly and the 3rd forestock rope dolly：The assembly pulley winding of 3 multiplying powers, i.e., the
The operating rate of two forestock rope dollies is the 2/3 of the 3rd forestock rope dolly, and the range ability of the 3rd forestock rope dolly is
3L1/4, then the range ability of second forestock rope dolly is L1/2；
Make to use 1 between first forestock rope dolly (farthest from main carriage) and second forestock rope dolly：2 multiplying powers
Assembly pulley is wound, i.e., the operating rate of first forestock rope dolly is the 1/2 of second forestock rope dolly, second forestock rope
The range ability of dolly is L1/2, then the range ability of first forestock rope dolly is L1/4.
Therefore, the operation stroke of forestock rope dolly is just by front side (extra large side) stroke quartering of main carriage 1；Similarly, after
Ask the operation stroke of rope dolly that rear side (land side) stroke trisection of main carriage 1, five support rope dollies 3 operation strokes and master is small
The front and rear operation stroke corresponding relation of car 1 is as shown in Figure 6.
Wound in addition, having on forestock rope dolly on 4 pulleys and preceding crossbeam end carriage between 6 pulleys into 4 multiplying powers, rear big beam-ends
2 pulleys on beam on 4 pulleys and butt rope dolly and between also wound into 4 multiplying powers, therefore forestock rope dolly and butt rope
Trolley travelling speed is identical, i.e. L1/4=L2/3.
The support rope dolly of the utility model ship unloaders five has taken into full account that ultra-large type laden vessel needs to be equipped with large-scale over-long extension
Away from ship unloaders requirement, compared with conventional four support rope carriage devices, (extra large side) it is small to add a support rope on front side of ship unloaders
Car 3 so that holding in the palm the dolly quantity of rope increases, and can support longer steel wire rope 4, meets being actually subjected to for increase ship unloaders castor
Ask；A set of weights tensioning apparatus 5 is added at crossbeam intermediate transverse girder before ship unloaders, it is increased in steel wire rope 4 and pulley quantity
In the case of, the tensioning state for holding in the palm rope winding system can be fully ensured that so that dolly winding system stable movement.
