| 摘要 |
The invention relates to a spud carriage biasing system comprising a first hydraulic tensioning cylinder (10); a first low pressure tensioning accumulator (15) in fluid communication with a first pressure chamber (11) comprised in the first cylinder (10); a second hydraulic tensioning cylinder (20); and a second low pressure tensioning accumulator (25) in fluid communication with a second pressure chamber (21) comprised in the second cylinder (20). The biasing system (1) further comprises two sets of two connected hydraulic cylinders (30, 40, 50, 60). The first set comprises a third hydraulic cylinder (30) and a fourth hydraulic cylinder (40), wherein a piston rod (33) of the third hydraulic cylinder (30) is connected with a piston rod (43) of the fourth hydraulic cylinder (40). The second set comprises a fifth hydraulic cylinder (50) and a sixth hydraulic cylinder (60), wherein a piston rod (53) of the fifth hydraulic cylinder (50) is connected with a piston rod (63) of the sixth hydraulic cylinder (60). Further, a third pressure chamber (31), which is part of the third hydraulic tensioning cylinder (30), and a fifth pressure chamber (51), which is part of the fifth cylinder (50) are in fluid communication with the first pressure chamber (11), which is part of the first cylinder (10), and a fourth pressure chamber (41), which is part of the fourth cylinder (40) and a sixth pressure chamber (61), which is part of the sixth cylinder (60) are in fluid communication with the second pressure chamber (21). |
