Description
Technical field
The invention belongs to ship equipment technical fields, and in particular to a kind of double rigidity are double to pre-tighten shock mitigation system.
Background technique
Dredger is a kind of high technology content ship, and guide pile is the important feature component of dredger.One section of guide pile is inserted
Enter in silt, the other end is connected with hull, and during the work time, environmental load and service load suffered by dredger are through transmitting most
It acts on guide pile eventually.Since dredger wind and wave resistance is poor, suffered dynamic loading reaches guide pile, can guide pile be generated
Fatigue rupture.Therefore, reducing influence of the ship motion load to guide pile by installation shock mitigation system is to prolong its service life
Important way.
Summary of the invention
The purpose of the present invention is to provide a kind of double preload shock mitigation systems of double rigidity, for improving dredger sea-keeping and peace
Entirely.The shock mitigation system can reduce hull to the active force of guide pile, weaken fatigue rupture, prolong the service life.
The object of the present invention is achieved like this:
A kind of double rigidity are double to pre-tighten shock mitigation system, including trolley 1, damper 2, linking arm 3, sliding rail 4 and guide pile；Trolley
1 is fixed on dredger by sliding rail 4 and linking arm 3；Damper 2 is arranged on the linking arm 3 of side, and damper is double bullets
Spring structure is connected using ring flange mode with linking arm 3；Guide pile passes through the upper anchor ear 5 of trolley and lower anchor ear 10 is inserted into mud
In sand.
Linear bearing 6 is disposed in the upper anchor ear 5 and lower anchor ear 10；Upper bearing (metal) 7, middle (center) bearing 8, lower bearing 9 have respectively
Two and trolley two sides are arranged symmetrically in, upper bearing (metal) 7, lower bearing 9 are connected with linking arm 3, and middle (center) bearing 8 and sliding block, sliding rail connect
It connects.
The damper includes the spring A13 and 14, two outer housings of spring B, axis, limit spiral shell of two different-stiffness coefficients
Female, adjusting nut, the first spring 13 apply pretightning force by adjusting nut with second spring 14；First damper shell 11,
There is sliding bearing in two damper shells 12；The equal fixed and arranged of stop nut, adjusting nut, sliding bearing is on axis 21.
The beneficial effects of the present invention are: the double shock mitigation system design principles that pre-tighten of double rigidity are simple, have clearly structure,
It is readily produced and is applied on dredger.This system reduces influence of the ship motion to guide pile, weakens the fatigue of guide pile
It destroys, can increase the service life of guide pile, and then improve the economic benefit of dredger.

Specific embodiment
Specific embodiments of the present invention will be further explained with reference to the accompanying drawing:
In figure: 1. trolleys, 2. dampers, 3. linking arms, 4. sliding blocks and sliding rail, anchor ear on 5., 6. linear bearings, axis on 7.
It holds, 8. middle (center) bearings, 9. lower bearings, 10. lower anchor ears, 11. first damper shells, 12. second damper shells, 13. first bullets
Spring, 14. second springs, 15-16. stop nut, 17-18. adjusting nut, 19-20. sliding bearing, 21. axis.
The present invention relates to a kind of double preload shock mitigation systems of double rigidity.Double rigidity are double pre-tighten shock mitigation systems by trolley with
Damper composition.Trolley is fixed on dredger by sliding rail and linking arm.Guide pile passes through in trolley insertion silt particle.Trolley
Dredger six degree of freedom irregular movement is switched to rotation of the spud pile around lower extreme point by structure.Damper is housed on linking arm, is subtracted
Shake device has double-spring structure, and two spring rates are different and apply pretightning force.Within the scope of pretightning force, the load of ship motion generation
Lotus will not cause the movement of guide pile；When the load that ship motion generates is greater than pretightning force, damper work weakens hull fortune
The dynamic influence to guide pile
Referring to Fig. 2, double rigidity are double to pre-tighten shock mitigation system, by a trolley (1), four linking arms (2), two dampers
(3) and sliding block is formed with sliding rail (4).Damper (3) is arranged on the linking arm (2) of side, is connected using ring flange mode.
Referring to Fig. 3,4, guide pile is passed through in the upper anchor ear (5) and lower anchor ear (10) insertion silt particle of trolley.Arrangement in anchor ear
Have linear bearing (6), guide pile can carry out rotate in a circumferential direction movement and axial movement.Upper bearing (metal) (7), middle (center) bearing (8), lower axle
Hold (9) respectively there are two, be arranged symmetrically in trolley two sides.Upper bearing (metal) (7), lower bearing (9) are connected with linking arm (2), axis
It holds (8) to connect with sliding block, sliding rail (4), and then trolley is fixed on dredger, the six degree of freedom irregular movement of ship is influenced
It is converted into moving around endpoint for guide pile.
Referring to Fig. 5, damper passes through adjusting nut there are two the spring A (13) of different-stiffness coefficient and spring B (14)
(17.18) apply pretightning force.Have sliding bearing (19.20) in damper shell a (11), damper shell b (12), reduces axis
(21) force of sliding friction.Stop nut (15.16), adjusting nut (17.18), sliding bearing (19.20) fixed and arranged exist
On axis.In practical application, damper shell b (12) is connected with trolley, it is assumed that its is motionless.Damper shell a (11) is if to the right
It is mobile, it need to first overcome the pretightning force of (13) spring A；When it moves right, stop nut (15) and damper shell b (12) are protected
Relative position is held, spring B (14) decrement does not change, and damper shell a (11) will squeeze spring A (13).Damper shell
Body a (11) need to first overcome the pretightning force of spring B (14) if being moved to the left；As it moves towards the left, stop nut (16) together to
It moves left, spring A (13) decrement does not change, and adjusting nut (18) will squeeze spring, generates elastic force.
A kind of double rigidity are double to pre-tighten shock mitigation system, including trolley and damper, and wherein damper is arranged in trolley linking arm
On, trolley utilize the structures such as linear bearing and sliding block, sliding rail, by the six-freedom motion of dredger be converted to guide pile around
Lower extreme point movement；Damper main member has the spring of two different-stiffness, two outer housings, axis, stop nut, adjusting nuts
Deng.Pretightning force can be applied to spring by adjusting nut；Assuming that wherein a shell is motionless, another shell is moved forward or backward
It needs to overcome pretightning force, and can only cause wherein that the variation of telescopic spring amount, another telescopic spring amount do not change.
