Detailed description of the invention
The present invention uses oil cylinder turning device, comprise turning lifting oil cylinder 22 and upset portal frame 26, when after the first outrigger 1 above and the second outrigger 7 indentation the 3rd outrigger 13, drawn by steel rope (the 3rd outrigger draws cable 16) and be adjacent on upset portal frame 26; When outrigger (comprising the first outrigger, the second outrigger and the 3rd outrigger) is regained, outrigger is pressed on upset portal frame under the effect of deadweight, is slowly shunk, outrigger is dropped on hull 18 storage by turning lifting oil cylinder.When outrigger stretches, by turning lifting cylinder jacking outrigger to certain position, outrigger rotates forward again under the effect from gravity, and under the constraint of steel rope, outrigger slowly turns forward appropriate location, then the first outrigger and the second outrigger are stretched out.Flexible very simple.
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figures 1 to 6, a belt conveyor for self-unloading oceangoing ship outrigger telescopic turning combined type, primarily of the first outrigger 1, second outrigger 7, the 3rd outrigger 13, base 24, upset portal frame 26, main portal frame 17, winch 21, turning lifting oil cylinder 22 and retractable driving device composition.
Described first outrigger front end is provided with home roll 2 and the first outrigger upper supporting roller 3 before the first outrigger.Described second outrigger is provided with the second outer frame sliding track 12.The belt conveyor of described self-unloading oceangoing ship outrigger telescopic turning combined type also comprises the 3rd outrigger adapter shaft 23, main portal frame top angle pulley 25 bottom upset portal frame S. A. 11, main portal frame back stay adapter shaft 20, main portal frame back stay 19, turning lifting oil cylinder.
Connection mode: 1) the first outrigger 1 is connected with the second outrigger 7 by the first outrigger tail roller 6.2) the second outrigger 7 is connected with the 3rd outrigger by the second outrigger tail roller 9.3) the 3rd outrigger is connected with fore base S. A. 14 and hull by the 3rd outrigger.Described 3rd outrigger draws cable 16 through main portal frame top angle pulley 25, is connected to winch 21.
Type of drive: (comprising following three parts)
1) driving is shunk.As shown in Fig. 1, Fig. 5 and Fig. 6, flexible one, cable is fixed on outrigger and stretches cable attachment point II 30, flexible cable extends to the first outrigger tail angle pulley 5, commutate to the 3rd outrigger to stretch cable fixed pulley 27, commutate to the second outrigger tail angle pulley 8, commutate to the 3rd outrigger again to stretch cable coaxial fixed pulley I 27-1, commutation connects driven roller.When the first outrigger and the second outrigger shrink, driven by driven roller and shrink.
2) driving is upheld.As Fig. 1, shown in Fig. 5 and Fig. 6, the other end of flexible cable is fixed on outrigger and stretches cable attachment point I 28, and angle pulley 10 before extending to the 3rd outrigger, second outrigger tail commutates coaxial pulley I 8-1, commutate to angle pulley 4 before the second outrigger, commutate to the first outrigger tail to commutate coaxial pulley 5-1, commutate before commutating to the second outrigger coaxial pulley 4-1, second outrigger tail commutates coaxial pulley II 8-2, commutate before commutating to the 3rd outrigger coaxial pulley 10-1, commutate to the 3rd outrigger to stretch cable coaxial fixed pulley II 27-2, commutate to driven roller again, a whole rope is formed with the cable that draws realizing shrinking.When the first outrigger and the second outrigger are upheld, driven by driven roller and uphold.When (i.e. two relative sides of driven roller) upward direction in two driven rollers is rolled, the first outrigger and the second outrigger can outwards be upheld; Meanwhile, the flexible cable that actuating device is regained is fed in the assembly pulley shrinking and drive, and the two reaching flexible cable realizes one and stretches a contracting and be synchronized with the movement.
3) upset drives.As shown in Figures 1 to 4.When outrigger needs to regain, when the first outrigger and the second outrigger shrink behind the 3rd outrigger midfield, winch 21 leaves and cheats contraction the 3rd outrigger and draw cable 16, draw cable pulley 15 that whole outrigger is promoted upset by the 3rd outrigger, abut against on upset portal frame 26, continuation operation winch 21 shrinks the 3rd outrigger and draws cable 16, and turning lifting oil cylinder 22 is compressed under the pushing of the 3rd outrigger 13, until outrigger crosses center of gravity vertex; Operation turning lifting oil cylinder 22, open to cheat and initiatively retract, outrigger is turned to outrigger deposit position with the speed of turning lifting oil cylinder 22 under the effect from gravity, makes outrigger be in operational configuration position, reaches the object of withdrawal.
When outrigger needs to stretch out, portal frame 26 will be overturn together with outrigger jack-up, and make outrigger be turned to desired location; In the process, main portal frame 17 is drawn cable 16 suspended on by the 3rd outrigger, is also improved upset simultaneously, until be that the main portal frame back stay 19 of folded state is straightened originally; Start winch, start to unclasp the 3rd outrigger and draw cable 16, continue jacking turning lifting oil cylinder 22 simultaneously, outrigger is overturn and crosses center of gravity vertex, then under the effect from gravity, the speed with winch is turned to forward operating angle position; Again by above-mentioned 2) uphold the extension process that the program driven completes outrigger, make outrigger reach mode of operation desired location.
