Preferably, the intermediate state of the linear system system 5 of spud carriage 2 or so-called immunization with gD DNA vaccine (are shown in such as Fig. 2 Out) can with work guide pile 3 and/or accommodate it the substantially vertical position of spud carriage 2 it is corresponding.Described non-loaded In the case of, linear system system 5 First Line 6 and the second line 7 can compensate one another and/or the line 6,7 can be biased roughly equally, especially It is outside.The immunization with gD DNA vaccine of linear system system 5 can be with initial, the intermediate or non-loaded feelings of spud carriage bias system 1 Condition is corresponding, as shown in Figure 3.Preferably, high pressure limitation accumulator 80 is provided in the 7th pressure chamber 32 and the 8th pressure chamber 62 Back pressure, the back pressure are so high that in the initial position of spud carriage bias system 1 corresponding 30 He of third cylinder The piston 34,64 of 6th cylinder 60 is pulled to its outermost position (as shown in Figure 3), and wherein piston will be corresponding in the outermost position Third pressure chamber 31 and the 6th pressure chamber 61 volumetric constraint to its minimum value.Preferably, in the initial position of bias system 1 In, the first low pressure is tensioned accumulator 15 and the second low pressure tensioning accumulator 25 provides relatively low pressure, wherein described relatively low Pressure without high enough to overcome by the fluid of the 7th pressure chamber and the 8th pressure chamber provide (such as by means of high pressure limit store Can device 80 pressurize) back pressure move the corresponding piston 34,64 of the hydraulic cylinder of two groups of two connections, but it is wherein described opposite Low pressure can be sufficiently high to provide the bias force of the line 6,7 of pre-tensioner linear system system 5.
During the use of spud carriage bias system 1, spud carriage 2 can be temporarily fixed to operating position 2a, 2b, In 2c, so that it cannot temporarily be moved forward or rearward substantially.As described above, corresponding line 6,7 can be stretchable, And it can be absorbed when spud carriage 2 is tilted relative to hull 103 around its generally vertical rotation axis 108 and act on ship The associated at least part power of the torque on connector between the hull 103 of oceangoing ship and spud carriage 2.When acting on work When guide pile 3 and/or the power acted on spud carriage 2 increase, corresponding line 6 is for example applied by corresponding line guide 72 The power being added on corresponding hydraulic tensioning cylinder 10 rises to this degree, so that the power becomes larger than by being located at described first The power that hydraulic fluid in first pressure room 11 in cylinder 10 applies.Therefore, as shown in figure 4, a part of fluid be pushed out it is described First Room 11 is tensioned accumulator 15 towards associated first low pressure, so that absorption is in spud carriage 2 and/or guide pile The increased power of at least part institute and/or torque on 3.Meanwhile as described above, another single line 7 tends to relax.When first low For pressure tensioning accumulator 15 when absorption is applied to a part of power on First Line 6, the second low pressure is tensioned accumulator 25 can be second By the way that other hydraulic fluid forces are caused second into second pressure room 21 when the tension that line 7 is applied on the second cylinder 20 reduces Line 7 is maintained under enough tension.
When corresponding line such as First Line 6, which is applied to the power on corresponding hydraulic tensioning cylinder 10, to be reduced, by corresponding low The pressure that pressure tensioning accumulator 15 applies will cause the piston of the first cylinder 12 to move back towards its initial position, to hinder the One line 6 will relax or relax too much.Meanwhile when the power being applied on corresponding first tensioning cylinder 10 by First Line 6 reduces, By the second line 7 be applied to the power on the second tensioning cylinder 20 will increase, thus by the piston 24 of the second cylinder towards its initial position to It pushes back dynamic.When the torque on the connector being applied between ship and spud carriage disappears, spud carriage bias system 1 Its initial position as shown in Figure 3 will therefore be moved back to.
On the other hand, when corresponding line such as First Line 6 be applied to the power on corresponding hydraulic tensioning cylinder 10 for example by When increased torque further increases, corresponding pressure chamber such as first pressure room 11 and fluidly connected corresponding Low pressure is tensioned the pressure increase in the flow of pressurized side of accumulator 15.At specified point, the Fluid pressure is more than by the 7th pressure The back pressure that fluid in power room 32 applies.Then, the fluid in third pressure chamber 21 makes the piston 34 towards the 7th of third cylinder 30 Pressure chamber 32 is mobile, until the pressure in third cylinder 30 is balanced, as that can see in Fig. 5.Pass through mobile third cylinder 30 Piston 34, the piston 44 of the connection of the 4th cylinder also moves, to increase the second pressure room 21 of the 4th pressure chamber 41 and interconnection In Fluid pressure.Therefore, the second hydraulic tensioning is caused by the increased power that First Line 6 is applied on the first hydraulic tensioning cylinder 10 Cylinder 20 applies bigger power on the second line 7, to hinder the relaxation of the second line 7 too many.
Pressure current when the increased power of institute being applied on the first cylinder 10 by First Line 6 reduces, in the 7th pressure chamber 32 Body can cause third piston 34 to be moved back at least to a certain extent, return to the first pressure so that fluid be pushed from third pressure chamber 31 Power room 11, to cause for example keep the foot on First Line 6 by the first tensioning guide 72 that the second line guide 72 is formed Enough tension.Meanwhile the movement of third piston 34 causes the piston 44 of the connection of the 4th pressure cylinder to be moved, to increase the 4th The volume of pressure chamber simultaneously reduces the Fluid pressure in second pressure room, so that can be to for example formed by the 6th line guide 76 Two tensioning guides 76 are largely tensioned the second line 7 and are hindered.When the power being applied to by First Line 6 on first cylinder 10 When further reducing, the piston 34,44 of the interconnection of third cylinder and the 4th cylinder is removable back to its initial position, as shown in Figure 4. When the power further decreases, line 6,7 accumulator 15 can be tensioned mainly by means of the first low pressure and the second low pressure is tensioned accumulation of energy It device 25 and is tensioned with the first cylinder 10 of corresponding accumulator 15,25 connection and the second cylinder 20.
On the other hand, in the power being applied to as First Line 6 on first hydraulic tensioning cylinder relative to situation shown in Fig. 5 more When further increasing, the first low pressure is tensioned accumulator 15 and high pressure limitation accumulator 80 can absorb the additional power of at least part. It should be pointed out that spud carriage bias system can advantageously comprise one or more safety valves, the safety valve can hinder system 1 In pressure reach critical value.For example, the first safety valve 16 can be set to be in fluid communication with first pressure room 11 and/or second pacifies Full valve 26 and second pressure room 21 are in fluid communication.Preferably, corresponding pressure valve can be fluidly connected to storage container, such as so as to Hinder pressure fluid contaminant water and/or environment.
