The weight of object, collect statistics obtain single PSV and are lauched total weight to be 2625 tons, and oblique building berth slope is 1:20, inquires oblique building berth table
Face coefficient of friction, and while being lauched in conjunction with previous ship type, collects after the empirical data that summarizes is modified and is calculated along oblique building berth table
Tractive force size when face glides is 95 tons.
Two, it is lauched traction device and prepares and be lauched traction arrangement
1 outside plate of hull, two side draw eye plate 21 arranges 4 altogether, for the connection of pulley blocks 6 and hull 1, is welded and fixed, often
50 tons of load are only appraised and decided, amounts to 200 tons, greater than 95 tons of tractive force when gliding.
Guide roller 22 in the middle part of 1 outside plate head end of hull, outfit appraise and decide 20 tons of guide rollers of load, are weldingly fixed on hull 1
On head end outside plate, for connecting two groups of pulley blocks 6 on two arine railways 1, it is made to keep synchronizing.To be supervised in real time convenient for naked eyes
It surveys, a red cloth item 20 is fastened on tackle steel cable 7, checks whether simultaneous observation red cloth item 20 is sent out in 2 folding process of hull
Raw displacement, determines two tackle pulleys, 6 synchronous situation.
Two sets of tackle pulleys 6, it is desirable that each coaster for selecting the two 50 tons 4 above models of wheel constitutes tackle pulley, every group of tackle pulley
After fixed pulley movable pulley subtracts power, 7 pulling force of tackle steel cable of output end is 5.7 tons.According to the existing tackle rigging model of factory,
Scene has actually selected the coaster of 50 ton of 6 wheel, 80 ton of 5 wheel, two kinds of models to constitute tackle pulley 6.
Hoist engine 9 requires elevator pulling force to be greater than 5.7 tons.According to the existing hoist engine device model of factory, scene is practical to be selected
The hoist engine 9 that two pulling force are 20 tons.Hoist engine 9 is placed on 1 end of arine railway, passes through between hoist engine 9 and arine railway 1
Code plate 1491 is welded and fixed, and wears anchoring steel wire rope 8 by two pulling force eye plates 22 that bottom is welded and connect admittedly with anchor block 10
It is fixed.
Anchor block 10 selects two 30 tons of kentledge to serve as, with anchor block connection 101 rigid solder of crossbeam connection, anchoring
10 sets of block at 1 end ladder of arine railway, and respectively plus 30 tons of emergency ballast anchoring iron block 102 pendant is fallen in building berth in building berth
It is increased below end and increases anchor force below anchor force end, prevent anchor block 10 from falling off from 1 end of arine railway.
Tackle steel cable 7 requires to select the wirerope for being greater than 28mm diameter, and the rupture pull force of wirerope meets calculated result.
5 tonnes of guide rollers that slideway guide roller 5 selects guide angle little, choosing when guide angle reaches 360 ° approximate
With 20 tonnes of guide rollers, slideway guide roller 5 is weldingly fixed on 1 steel plate of arine railway.
Anchoring steel wire rope 8 requires to select the wirerope for being greater than 36mm diameter, and the rupture pull force of wirerope meets calculated result.
It is connected between anchoring steel wire rope 8 and 2 liang of anchor block pulling force eye plate, hull side draw eye plates 21 by steel shackle.
The stop block 4 for being lauched slide plate side is the small iron block of tooling made of several pieces of steel plate butt weldings, is welded on and is lauched slide plate
Side, the trigger 3 on hooking arine railway 1, is kept fixed hull 1.Specific position is according to coaster steel wire
Rope 7 length, 6 windings of tackle pulley, anchoring steel wire rope 8 length computation get, this PSV ship launching draw when, factory
The tackle steel cable 7 of outfit is 700 meters, and ship initial position moves to safe launching position need to move 90 meters altogether, be divided under 3 times
It moves, as shown in Figure 5,6, moving distance is respectively 30 meters, 24 meters, 36 meters, after moving down distance arrival every time, the position of stop block 4
It is placed exactly in the position of lower section 1 trigger 3 of arine railway, holds up slideway trigger 3, hooking lives stop block, and 4 keep hull 2
It is motionless, it is collapsed again after 6 removal load of tackle pulley, repetition is drawn next time, until hull 2 moves down into safe launching position.
