Abstract
The invention relates to an arrangement (206) for manually releasing nautical life saving equipment, e.g. containers for inflatable life rafts. The release arrangement (206) is located as a connecting link between a first rope arrangement (205) and a second rope arrangement (215) adapted to fixating the life saving equipment. The second rope arrangement (215) forms a loop (213) encircling the first rope arrangement (205). The first rope arrangement (205) is fixed to a connecting stick (207) so that the connecting stick (207) together with the first rope arrangement (205) forms a stop preventing the loop (213) of the second rope arrangement (215) to run along the first rope arrangement (205). The connecting stick (207) is adapted, at release, to turn around an axis formed by the loop (213) of the second rope arrangement (215). The axis is orthogonal to the longitudinal axis of the rope arrangements. The force needed to release the arrangement (206) is rather independent of the tension forces in the rope arrangements (205, 215).
Description
Technical field
The present invention relates to be used for the device of manual releasing navigation life, described navigation life for example is the container of inflatable life-saving ship or raft.
Background technology
All now big ships all are equipped with in case of emergency as life boat or other the similar equipment of succouring ship.These rescue ships are provided with some devices in order to the ship of automatic release lifesaving in case of emergency usually.Pressure by sensitive context changes can trigger automatic release mechanism, discharges the navigation life when being subjected to the elevated pressures of the hydraulic pressure under for example a certain degree of depth with box lunch.Under the situation of inflatable rafts, the inflation of raft triggers when raft discharges or triggers after raft discharges at once.Therefore, under the shipwreck situation, the raft that is discharged just is inflated and moves towards the water surface, so that as liferaft.
Even life is provided with automatic release mechanism, still need be liferaft or life boat outfit manual release mechanism.Exist and wish that personnel self can discharge the situation of liferaft.If this may be the situation under the occasion of presence of fire or big fire and beaching.Even under the situation of shipwreck, use the automatic release system to be considered to the alternative scheme of manual releasing usually.Usually manual releasing life preferably is so that as far as possible promptly be in perch.The purpose of automatic release is to carry out guaranteeing under the manual releasing situation that not free life can use.Therefore, importantly can be fast under these occasions and easily discharge liferaft or life boat.For inflatable rafts or life boat, they are generally held in the container.But such container is fastened to suitable bracing frame on the relevant ship by buckled up band etc., for good and all is fastened on the bracing frame and the other end that makes this band is fastened to bracing frame releasedly with the common standard mode that comprises what is called " release hook " in the hole that is hooked in the bracing frame or " Slip Hook " and remains on the bracing frame releasedly by an end that makes band.General custom is the static pressure release gear is arranged on the hand release of Slip Hook for example and for good and all is fastened between the strap ends on bracing frame or the deck.
Release hook comprises: eyelet portion, this eyelet portion is suitable for the back bent-up end of stay bolt band and has the outstanding base portion of the hook of the free end far away that extends back, wherein this free end comprises the maintenance protrusion at the place, end, is used for retaining ring around the base portion of hook and the anchor ring of corresponding free end.Make the free end of hook can be, and extract preventing after this locked by the locking hoop is trapped on the maintenance protrusion on the free end that is being positioned at hook by the retaining hole in the bracing frame.Rearwardly projecting free end can flexibly be pressed onto in the base portion of hook, make: for the bonded assembly of manually realizing hook is provided discharges, hook can be compressed fully discharging the locking ring from described maintenance protrusion and to make hook from its hole, grip state turnover and withdrawal thereafter, thereby discharge floatable container at bracing frame.
But the release hook of having found the tradition setting is with respect to there is safety problem in their desired release easiness.Therefore, when using initial slack-free band, be exposed at band under the situation of humidity increase level, the tension force of band further increases, and cooresponding high tension provides the drawing in the release hook in band, force the free end elasticity pivot of release hook to leave the stem bar of hook thus, thereby in aforementioned locking ring, produce under the outside slack-free situation that significantly increases, be difficult to by the manual squeezing release hook its release.In addition, release hook must be by outwardly-bent realizing that outer hook portion comes release from keep gripping away from the transverse translation of retaining hole, and be difficult to carry out the essential so outwardly-bent of hook because the pulling force that increases in the eye end of hook is feasible.This device shows the fastening system that needs are other, therein, irrespectively guarantees quite easily to provide release with the tension force size in the band.In addition, manual release mechanism should be able to tolerate its residing suitable rugged environment, and can not discharge owing to corrosion or other influence from environment, and for example, preferably, the low temperature of its parts can not produce injurious effects to it with freezing.
At EP 1,193, in 172, proposed to be used for the device of the manual releasing of navigation life.At EP 1,193, during 172 background technology is discussed, mentioned the problem that the manual releasing liferaft exists when having high tension in keeping band.But EP 1,193, and the test of carrying out on the device that discloses in 172 has shown relating under heavy lift and the high tension state needs more performance.In addition, EP1, the system that discloses in 193,172 comprises suitable complicated apparatus, this device comprises need be placed into a plurality of together parts.In addition, if need to discharge and closed again this device for test, as if aspect device closed again, this device is inferior to the Slip Hook device.And EP 1,193,172 for this device under abominable and corrosive environment situation will how to work and when be in cold snap and icing situation this device will how to work less than putting down in writing.
Therefore, need a kind of improved for example release gear of the life of the container of inflatable rafts that is used for manually discharging, discharge to realize this device security and fast speed.
Summary of the invention
The object of the present invention is to provide a kind of delivery system of navigation life of the container that is used for for example inflatable life boat or raft, to overcome the above-mentioned shortcoming in the prior art solution.
In an embodiment of the invention, a kind of be used for manual releasing for example the device of the navigation life of the container of inflatable liferaft be arranged to be suitable for fixing life, the connecting rod between first rope device and second rope device.Second rope device forms the fake around first rope device.First rope device is fixed on the pipe link, the backstop that the fake that makes pipe link form together with first rope device to prevent second rope device is advanced along first rope device.When discharging, pipe link is suitable for winding by the formed rotational of the fake of second rope device.This orthogonal axe is in the longitudinal axis of rope device.
Therefore, when being applied to rope effectively in the opposite direction, pipe link will engage two rope devices, so that separately restrict.
In following example, pipe link comprises the front panel that is connected to two side panels, and described two side panels are basically perpendicular to described front panel at least a portion from the downside of described front panel along the longitudinal axis of pipe link and extend.This structure also can be solid, but preferably uses said structure for saving in material.No matter this structure is to be made by the sheet material of for example bent sheet metal, still make by solid material, it all is configured to: owing to wind the axis effect short lever arm that formed by first rope device and second rope device acts on the low relatively friction force of the side of pipe link and has than the long lever arm by second rope device, so little from the momentum of the turning effort of second rope device.This device will make pipe link be locked in the position near the equilibrium point of applied force.
The settling position of pipe link depends on that second rope device act as by the feasible fact of neutralization each other of its power on opposite rotation direction.Except this stabilizing device, also exist act on the bar from rope device--mainly be the friction force from second rope device, this power helps pipe link is remained on its locked position.Therefore, must balanced rotation power make a concerted effort and make it be lower than synthetic friction force so that pipe link work.
Applied force is relatively independent of the size of rope device.But, think the design of bar--for example the width of front panel and the angle between shape and front panel and the side panel influence described power and they and act on possibility on the bar.For example, if bar is flat round bar, do not have any projection or impression, this will be difficult to have any power that the such pipe link self of restriction rotates and discharges that act as.The power at lucky that some place that acts on the fake of second rope device will overwhelm along the power of opposite directive effect, and if locking device as described below is not set, then pipe link will rotate and discharge.But the bar of ovalize can be worked, as long as this bar is enough wide and enough flat and turning effort that lucky that place that can provide enough control effortes to be equilibrated at fake to opposite turning effort acts on.
Pipe link also can be provided with locking device, and this locking device is suitable for preventing that pipe link from by mistake discharging.In one embodiment, locking device comprises locking pin, this locking pin is coupled in the hole that is arranged in each side panel, if perhaps this structure is solid member then is coupled in the hole of running through this solid member, extends with the longitudinal axis that is basically perpendicular to pipe link.Owing to when forming frenulum, be positioned at part mutual action on the every side of connecting pin, so this locking pin will limit the pipe link rotation with second rope device.
The front panel of pipe link also can be provided with the hole that is suitable for holding first rope device, so that first rope device is fixed on the pipe link.In one embodiment, the downside of front panel is provided with the maintenance bar that is arranged in the hole.This bar be arranged so that rope device can the side in hole from the upside of pipe link pass the hole and around keeping bar so that patchhole once more, enter at the opposite side in hole downside, so that rope device is fixed to pipe link from pipe link.In another embodiment, can provide two holes on pipe link, thus, rope device enters a hole and continues to enter another hole from downside from the upside of pipe link, so that form fake around pipe link, thereby rope device is fixed on the connecting pin.
This paper uses expression " rope device ".This expression will be construed to and comprise such as rope, line, band, chain, has substantially and rope identical function or can be as the device of the little bar of one or more pivot bonded assemblys of rope work etc.This expression also comprises uses several ropes or allied equipment as rope.Such rope device can comprise the part that different materials is formed.
" rope device " can also carry out surface treatment or be provided with cladded material in the position that is subjected to severe wear.These positions of rope device for example can be those parts that form fake, or those parts that contact with each other in its vicinity and contact with connecting pin when forming locking device.The part that second rope device forms pivot center can be formed by harder material.
In following part, used to form each rope of release gear and the specific dimensions and the design of various piece.These specific embodiments are only as example of the present invention.It will be obvious to those skilled in the art that it can use as design illustrated in this claim or the specification sheets and in inventive concept of the present invention the new embodiment of structure.For example, can change the form and the size in the residing hole of first rope device, and the position of this hole on pipe link.In one embodiment, two independent holes rather than a hole can be arranged.The position in hole can be tested and be drawn, and the position when making its generator near balance is to realize the release force of expectation.
In following example, trigger bar is made by crooked metal sheet, to form front panel and side panel.Obviously, this bar can otherwise form, for example its can form have with example in the upside of the same profile that illustrates and the pole spar of both sides, perhaps have other shape.The material that uses can be any material that is suitable for resisting from the harsh environment of salt solution and big temperature change.

The specific embodiment
In Fig. 1 of accompanying drawing, liferaft container 101 is shown.This container comprises first bottom 102 and second top 103 that is suitable for assembling each other, so that form the shell that holds raft.Container arrangement in support 104 and by on band 105 be fastened on the support, last band 105 extends downwards and is connected to hand release 106.This release gear is depicted as the Slip Hook 107 that generally uses, and Slip Hook 107 comprises the maintenance eyelet 108 that is fastened on the band.Slip Hook 107 also comprises upwardly extending fork branch 109, and fork branch 109 has protrusion 110 and is pivotally connected to cane 111 at its other end (base end) at its end.Locking ring 112 is fastening and can move along cane around the cane 111 of Slip Hook 107.Can release gear 106 lockings are on the throne with fixed container 101 by making fork branch 109 pass the retaining hole 113 that is arranged in the below of connecting device.
Can make the last portion close enough cane 111 of this branch and then the end that locking ring 112 can wear fork branch by push fork branch 109 pivotally towards cane 111, thereby discharge Slip Hook 107.This part is connected to from dynamic and static pressure and discharges on the parts of connecting device 114, discharges connecting device 114 from dynamic and static pressure in addition and is connected on the solid bottom of support 104 by following band 115.Therefore the release gear of band 105 not only can manually be worked but also can automatically be worked.By discharging fork branch 109 from locking ring 112, by when the described ring 112 of guiding overlaps the protrusion 110 of fork portion end, pushing fork branch 111 towards cane, thereby fork portion is discharged to rotate freely at its base portion, Slip Hook 107 will from its with the engaging of retaining hole 113 discharge, thereby break away from from its locked position.
Although making this device by many approach is being failure-free with band or line, confirmed that the power of manual releasing container may be too high aspect support or deck are connected.The essential characteristic that is used for the release gear of life aboard ship is to trigger easily to discharge.For example because the canting of ship or the shrinkage of band, will cause the increase of tension force in the Slip Hook from the increase of the power of band.The end of fork portion will by with band in the proportional power of the power that increases pivot and leave cane, and then make Slip Hook discharge difficulty.Another shortcoming of using Slip Hook to have is that it usually needs to carry out simultaneously two operations to discharge locking: push the cane and the fork portion of Slip Hook in the lump, and the locking ring is moved and protrusion by end and remove the constraint of fork portion along fork portion.Under the situation of freezing, to compare with release gear according to the present invention, Slip Hook is also relatively poor.When Slip Hook freezes,, become more difficult so discharge owing to need bigger power so that ice is broken.Smooth surface also makes and is difficult to catch release hook more, and makes that hook is discharged this is difficult to make the satisfied task of people difficulty more.
In Fig. 2 a, show later-model release gear 206.This device comprises long and narrow pipe link 207, and the function of pipe link 207 is corresponding to the function of Slip Hook among Fig. 1.Pipe link 207 is connected to rope 205, and rope 205 forms and is suitable for passing the fake 208 that hole 216 enters pipe link.At the dorsal part of pipe link 207, keep pin 217 so that carry out 205 non-releasably being fixed on the pipe link around restricting for described fake thereby be provided with.Preferably is locating apart from about 1/5 to 1/10 the distance of described end near end location in hole 216.When release gear was in locked position, pipe link was in by in second rope, 215 second fakes 213 that form near the end in hole 216.Thereby restrict and 205,215 engage by pipe link.When rope 205, the 215 caused tension force that exist in the release gear by pulling in opposite direction, prevent that by the locking device that forms by the mutual action between first rope 205 and the pipe link 207 fake 213 of second rope 215 from sliding.Pipe link 207 is located such that longitudinal axis is perpendicular to the y axle in the accompanying drawing.In addition, by the rope 205,215 caused power principal direction perpendicular to the y axle in the accompanying drawing.But when pipe link was in its position of rest or locked position, the longitudinal axis of this pipe link became the angle of about 30 degree with the XY plane when being in the XY plane by rope 205,215 caused power.This pass ties up among Fig. 2 b and illustrates better.In Fig. 2 b, automatic release device 214 also is attached to hand release 206.
In order to discharge this device, pipe link 207 is around rotational, described parallel axes forms (with reference to Fig. 2 a, rotation direction will corresponding to 216 farthest the ends from the hole that upwards spur pipe link 207 outside figure plane) in X-axis and by second rope, 215 fake 213.
In order to test invention, 3 series using different rope device settings are tested.In first test series, only use rope, and in second series, different frenulums is used the combination of line and rope, in tertiary system row, only use line.Change is applied to the power of pipe link by rope device and tests to measure the required power of hand release that discharges.
In Fig. 3, the pipe link 307 that is used for testing is shown: at Fig. 3 a with 4 different views, illustrate from directly over the upside (side elevation view) of the view specification pipe link 307 observed, in Fig. 3 b, illustrate under the downside (underside view) of the view specification pipe link observed, and in Fig. 3 c, upside lateral plan (lateral plan) down is shown.In Fig. 3 d, the view that (that is, near the short side of locking pin) illustrates pipe link 307 is shown from the front side, wherein upside (front elevation) down.
The ratio of pipe link 307, ratio and design are corresponding to the bar that uses in test.Therefore, bar was with 1: 1 scale.In Fig. 3, the different views of pipe link 307 shows in detail the different characteristic of bar.
But the connecting pin of being tested 307 shown in Figure 3 is only as how designing the successful example that pipe link (207,307,407) is realized ideal effect of the present invention.
In Fig. 3 a, be clearly shown that hole 316.The hole is suitable for holding rope device, and this rope device enters in a side, around keeping pin 317 and 316 opposite side withdraws from the hole, so that form the fake that rope device is fixed to pipe link.
In Fig. 3 b of trigger bar underside view is shown, the position that keeps pin 317 is shown.
In Fig. 3 c, the lateral plan of pipe link 307 is shown, comprise the release arm 318 and the side panel 319 of end of the front panel 322 of pipe link shown in it.In the figure, can see the position of locking pin 320.Locking pin 320 passes through hole 321 inserting side panels, and can be pulled out when needs discharge pipe link.In Fig. 3 d, locking pin 320 is shown better.
In Fig. 3 d, the front elevation of trigger bar is shown.Side panel 319 is shown to meet at right angles with front panel 322.In this view, be clearly shown that the shape of locking pin 320.Locking pin can be formed the shape of expectation by thin round bar.In the figure, it is to be noted, keep pin 317 quite thick.The thickness of sheetmetal that this device makes it possible to allow to form pipe link 307 is quite thin.It is solid to keep pin 317 preferably to make.When pipe link is in its as shown in Figure 2 locked position, will mainly be that mutual action and acting on keeps on the pin from the power of each rope device.Wherein one of rope device passes the hole and will cause around the layout that keeps pin to have the short lever arm concerning applying power.Even under the situation of brute force, the short lever arm will make the main body of the front panel that comprises pipe link and side panel can use quite thin sheetmetal to make.As seeing from figure, the radius that keeps pin is about 5 times (approximately 10mm) of the thickness (approximately 2mm) of sheetmetal.Keep pin for example to make by solid metal.Certainly, these sizes can change owing to the selection of material, the design of pipe link and the intensity of force that applies.
Test has illustrated that this device has and the relevant certain benefit of release easiness.Following test result shows the required power of release gear with disproportionate by the caused power of strain of rope, but keeps cooresponding constancy.Utilize different rope devices--be that different materials (traditional rope and line) carries out the test of hand release with different size (promptly changing the diameter of the rope device that is used for frenulum).The result is as follows:

In the test of carrying out, it is slightly proportional at lower area and tension force to trigger the required power of pipe link release, promptly is lower than the applied force that is approximately 1000N, and the required release force of triggering pipe link rotation is lower than 100N.When release gear stands than hightension--during promptly from 1000 to 15000N tension force, trigger pipe link and rotate required release force and be stabilized between 100N and the 200N.The required power of the bar that under any circumstance is rotationally connected can be greater than 200N.This phenomenon is caused by friction force (see figure 2) that increases between the side of pipe link and the adjacent rope and associating along the main force of rope longitudinal direction at least in part, wherein the friction force of this increase makes great efforts to make connecting pin to be held in place, and the main force makes great efforts to impel the rotational motion of connecting pin.
Further explanation for the phenomenon that exceeds this result is that pipe link is positioned at balance unstability position.Even pipe link remains on its locked position when not being subjected to any additional turning force, this balance also is that unsettled, such instability causes small power all to be enough to upset balance again making pipe link to rotate and discharge this device.Further be apparent that by this structure because bar hinders by the formed axis of fake of first rope, so its can only rotate along release direction, thereby more safely rotation.Therefore, this device does not have the risk of rotation, thus the stable locked position that end can not discharge.
In experimental investigation, the exact value of unclamping required release force for the rope that spurs release arm 318 and locking does not have detailed scheme.There is not tangible system difference in the power that between the rope of different size (diameter) and line, needs.This is because the inaccuracy and the appreciiable parameter of measuring equipment are caused by the influence of the change of rope device and applied force to a certain extent, for example, the diameter influence pipe link when discharging that forms the rope of first frenulum rotate around the thickness of axis, interconnecting caused friction force and also will have influence owing to different materials in the rope device and this rope device and trigger bar to the release force that is produced.
In further test, about when stand cold snap and parts when icing the functional of release gear release gear is tested.In this test, hand release 206 is provided with near automatic release device 214 shown in Fig. 2 b.Also provide the power that applies from about 2500 newton (N) of rope device (205,215) for test equipment.Test equipment is adjusted under the subzero 10 degrees centigrade temperature continues 20 hours.During initial 8 hours, equipment is per hour dashed pouring once with water smoke (fresh water).Last dash pouring after, equipment be adjusted under the identical temperature continue 12 hours again.When spending 20 hours, take locking pin 220,320 away.Compare with unregulated equipment, do not need extra power just can make locking pin 220,320 from its disengaging that engages with side panel 319.But, compare with the power of common needs, need some extra power to discharge through thermoregulator pipe link 207,307.Required power is measured as 200 to 300 newton.To the test shown in 3, no matter applied force how, desirable power should be slightly smaller than 200 newton according to table 1.Although required power increases a little in the equipment through regulating, show that the test of hand release is still carried out well when icing.
Can make some to trigger bar adjusts to help the release of pipe link.In Fig. 4, show the side elevation view (corresponding to the view of the pipe link 307 shown in Fig. 3 a) of 3 different embodiments.In Fig. 4 b, show pipe link corresponding to pipe link shown in Figure 3.In Fig. 4 a, revised front panel 422, make this front panel 422 narrower in the end that it forms release arm 418.This bar that diminishes gradually will help to have less friction force and make easier release pipe link.In Fig. 4 c, show another embodiment, wherein make the front panel 422 that comprises the part that forms release arm 418 be made broad.This device will help to have the friction force stronger than release arm shown in Fig. 4 b.
Certainly exist influence in order to pipe link is turned to the alternate manner of the release force of releasing position from latched position.For example, the surface of side panel (Fig. 3 b illustrates and be denoted as 319) can be processed into coarse and be provided with material surface to increase friction force, perhaps is provided with impression or projection rope is held in place and therefore increases required release force.The another way that influences required release force is the angle that changes between curved side panel (among Fig. 3 319) and the front panel (among Fig. 3 322).In this example, this angle is 90 degree, that is, and and the right angle.If making angle is the obtuse angle, that is, make each side panel crooked dorsad, then release force will increase.In addition, the curvature crooked and angle between side panel and release arm of plate-shape metal sheet is considered to influence the functional of hand release.Replace having curvature, panel can be two position bendings, and each bending for example is 45 degree, make the bendings of forming 90 degree together and the right angle that forms side panel 319 relative front panels 322.
In the illustrated embodiment, pipe link is provided with the safety locking pin, for can dwang and discharge pipe link, must remove this safety locking pin.Because locking pin only is intended to avoid being not intended under the unintentional rotation release arm situation to discharge, so even without such locking pin, release gear also will be worked.In the illustrated embodiment, locking pin is as illustrated in Fig. 4 d.Under the situation of a certain other locking device of expectation, it is conspicuous for those skilled in the art that the release gear of the appropriate device with any type is provided.In Fig. 5, show another example of safety locking device, wherein use with the interactional locking folder 520 of the parts of automatic release device 514 and replace locking pin.
In another embodiment of the present invention, first rope device can be fixed on the pipe link by a certain alternate manner.Use in first rope device under the situation of hawser, this hawser can be fastened in the hole of connecting pin by making this hawser pass the hole and tiing a knot at opposite side, so that this rope is fixed in pipe link.Therefore, although in each example professor how first rope device is fixed to preferred implementation on the pipe link, it will be apparent for a person skilled in the art that in inventive concept of the present invention, to have the multiple mode that this rope is fixed to connecting pin.
