Detailed description of the invention
Figure 1A, 1B and 1C show the various rotations of the two-electron atom assembly 5 being engaged in a pair freight container 10.Rotation about the freight container longitudinal axis is defined as heel (list) 15, and the rotation about freight container transverse axis is defined as trim (trim) 20, and the rotation about vertical axis is confirmed as rotation 25.
Fig. 2 shows the schematic configuration 30 of the bank crane for mobile single suspender.Herein, a pair reel 35 controls hawser 55,60,65,70, and these hawsers extend to the actuator 45 of hawser opposite end from reel 35.
Hawser is through dolly 40 and through the pulley of the spreader assembly 42 be positioned in the middle of reel 35 and trim actuator (trim actuator) 45.
When reel 35 tends to evenly operate hawser, trim actuator 45 single movement thus can stretch separately or the hawser that bounces back on every root hawser.This stretching, extension or retraction hawser achieve heel, trim or rotary hanger 42 just.
Such as, the hawser 55,60 that stretching, extension or retraction are engaged in laterally pulley relatively will realize trim, and the hawser 55,70 that stretching, extension is engaged in longitudinal pulley relatively will realize heel.In order to realize rotating, need to stretch or bounce back to be engaged in the hawser 55,65 of monoclinic phase to pulley.As mentioned above, these actions are applicable to single suspender.When not being single suspender but using during two-electron atom just to create trouble, this two-electron atom has the linkage (not shown) of the sling upper rack (head block) connecting suspender.The linkage of two-electron atom is used for separating sling upper rack in the horizontal plane, provides resistance in the horizontal plane instead of on the vertical plane thus.When trim action is by when producing the result identical with single suspender, it can not realize rotating or heel.By stretching the right hawser 55,65 of monoclinic phase, substitute rotary hanger, this will realize relative trim (being also two container customs relatively rotating in transverse axis) instead of required rotation.Therefore, the structure of hoisting crane can not realize the rotation of two-electron atom in this direction.By stretching hawser 55,70, this is elevated causing in freight container one and is realized diff-H to substitute heel suspender, instead of required heel.
Fig. 3 A to 3C shows the effect attempting rotating two-electron atom.In " neutrality " position of Fig. 3 A, two sling upper racks 75,76 are symmetrical about line of centers 80, and this line of centers 80 is a kind of imaginary lines downward by the central vertical of two dolly pulley rooms.
Fig. 3 C shows the effect being applied eccentric force by retraction angle hawser (corner cable) 100.In order to the weight of allocation set vanning, by the alerting ability of linkage 115, a sling upper rack 76 lifts 115 relative to another sling upper rack, and wherein linkage 115 can not resist out-of-balance force.
But if linkage can resist the upward component of the power redistributed, then result will as shown in Figure 3 B.Here, again, a hawser is contracted, and causes eccentric force to be applied on a sling upper rack 76.When the normal component of the power redistributed resisted by linkage, two-electron atom assembly moves thus no longer places about line of centers symmetry.This result is that two-electron atom rotates.Therefore, problem remains and how to lock linkage and linkage still can perform its radical function.
The embodiment of solution is as shown in Fig. 4 A to 4C.In the present embodiment, in question linkage 143 is some member parallel quadrangular configuration, and these components comprise upper beam 145 and underbeam 150 and upright body 157,158, and all these member spans are between pulley 135,140.
It should be understood that and can adopt the several multi-form of linkage that such as there is the scissor structure of centrally-pivoted axle, connect these beams of sling upper rack about this central pivotal.
The Core Solution of present problems is blocking device 143, comprises the framework 160 being installed to upper beam 145 and locking rammer (the locking ram) 155 installing upright body.As shown in figs. 4 a and 4 c, in order to make linkage rotate about pulley 135,140, due to the angle change between upper beam 145 and upright body 157, ramming and need retraction or stretch.
If ram 155 to be stopped moving, then linkage is prevented from rotating, and therefore sling upper rack is stopped moving on Relative vertical direction.As shown in Figure 3 B, this will have the power thus the effect that two-electron atom is rotated of redistributing hawser retraction.
Fig. 5 A to 5C shows two kinds of operational circumstances of blocking device, and wherein, Fig. 5 A has the oil cylinder 155 of the locking shown in Fig. 5 B, and Fig. 5 C shows oil cylinder 155 in unlocked position and allows the effect of sling upper rack relative to each other vertically movement.
Fig. 6 and 7A to 7D shows according to one embodiment of present invention for the hydraulic circuit 185 of blocking device.Here, loop 185 comprises pump line road 184, and the hydraulic oil of pump line road 184 supplied with pressurized is with operational lock oil cylinder 210 and fuel tank pipeline 182, and oil cylinder 210 and fuel tank pipeline 182 make hydraulic oil turn back to hydraulic fluid tank.In this loop, before it arrives oil cylinder, the pressure on pump line road is reduced to lower preset pressure, as 5-10 bar (bar).In the ordinary course of things, when sling upper rack keeps static, do not have External Force Acting on oil cylinder, the two ends of oil cylinder are full of compressed oil by under described lower preset pressure.In this case, due to the difference on the region between rod end and oil cylinder end, only make a concerted effort (net resultant force) by what give to extend for oil cylinder.But due to the preset pressure that this is lower, this will be not enough to any movement affecting linkage and the sling upper rack reconstructed only with joint efforts.One group of check (non-return) valve 195 is for guiding and allowing hydraulic oil to flow to meet the demand of whole hydraulic circuit on single predetermined direction, as the typical apply of hydraulic circuit.
To unlock to oil cylinder/rammer thus " release " rams relevant the first path (Fig. 7 C and 7D) via low-pressure safety valve 240, the level (the first predetermined threshold value) under this low-pressure safety valve 240 is set to allow oil cylinder to leave standstill to remain on little external load application.Such as, suspender motion in the normal operation period may produce vibration or the movement of freight container load, and this freight container load may produce Smaller load to the oil cylinder of blocking device.Be set to be enough to prevent oil cylinder from moving under this load relative to the pressure safety valve (PSV) of low predetermined threshold value.Only as an example, pressure safety valve (PSV) can be set to the first predetermined threshold value of 30 bar, even if this 30 bar is also enough to resist this load under rammer is in " release " situation.
In this case, suspender is in the ideal situation of the diff-H of the freight container that adjustment engages.When reduction by two freight containers, a freight container should contact platform (such as another freight container is static), a freight container is compared with another freight container, difference on applying load will force in linkage, and this linkage will transfer on locked cylinder, apply load 224 and increase its pressure.When pressure fully promotes and becomes the preset pressure higher than preset security valve 240, it is by breakthrough pressure safety valve thus therefore permission oil cylinder movement also makes linkage move.
When selecting change-over valve 235, higher pressure safety valve (PSV) can be passed by routing path (Fig. 7 A and 7B).This can routing path for making the overall rotation according to two-electron atom of the present invention.When applying external load 222 on locked cylinder, as the result that the hawser being engaged in pulley is retracted, being not enough to overcome the load of application compared with the level (the first predetermined threshold value) of lower security valve 240 thus oil cylinder is slided.Therefore, when requiring totally to rotate, change-over valve 235 is switched to another path by elevated pressures safety valve 245, and this elevated pressures safety valve 245 is arranged on elevated pressures (the second predetermined threshold value) to be enough to resist the pressure relevant to the rotary load 222 from hawser.But elevated pressures safety valve 245 is set to allow oil cylinder to slide when quite higher load 223 is applied, the diff-H that this load 223 is such as described before.This second predetermined threshold value pressure can be 200 bar, but can be determined by the normal design procedure for special applications.
By comprising elevated pressures safety valve 245, the overall benefit rotated can be realized, and not damage the risk of linkage, if but oil cylinder lock completely, the damage of linkage may occur.If not elevated pressures safety valve, but apply and stop completely, if a freight container is reduced on the platform higher than other freight containers accidentally, cause the situation of diff-H, oil cylinder locking will cause the permanent deformation of linkage completely.
Fig. 8 shows construction alternative of the present invention.Especially, Fig. 8 illustrates the hoisting system of the winding drum 35 with operation hawser 55,60,65,70, and hawser 55,60,65,70 ends at trim actuator 45.What Fig. 8 and Fig. 2 was different is configured to whether employ special cart 255.Dolly 255 comprises sliding wheel 280,270, and these pulleys optionally move 285,275 relative to dolly 255 like this.By the motion of pulley 280,270 in relative direction 285,275, this applies moment about vertical axis on two-electron atom 260,265.Owing to not relating to eccentric force, the alerting ability of linkage is incoherent, and two-electron atom is about vertical axis " rotation " thus.In this configuration, can apply to rotate on the two-electron atom not installing blocking device, therefore this structure is the rotation applying method more general than blocking device.
