技术领域technical field
本发明属于海洋工程技术领域，尤其涉及海上打捞技术，具体涉及模拟双驳船同步提升的液压升沉补偿试验平台。The invention belongs to the technical field of ocean engineering, and in particular relates to salvage technology at sea, in particular to a hydraulic heave compensation test platform for simulating synchronous lifting of double barges.
背景技术Background technique
近年来，随着我国海洋工程的不断发展，船舶种类不断增多，尤其是大吨位船舶数量明显上升，一旦船舶失事，海上应急抢救打捞作业就显得尤为重要。其中，液压同步提升系统作为出力大、效率高的打捞技术之一，如今被广泛应用于各类打捞工程当中。然而，海上工程不同于陆地，它是在驳船上进行的，由于海况的存在，在施工过程中，驳船会产生随机的波浪运动，出现钢缆受力不均的现象，因此同步提升过程难以保证，更危险的情况就是导致海上事故的发生，为了解决此难题，人们开始研究同步提升过程中升沉补偿装置的作用以及如何高效率的进行升沉补偿，为此搭建了模拟双驳船同步提升系统的试验平台。In recent years, with the continuous development of my country's marine engineering, the types of ships have continued to increase, especially the number of large-tonnage ships has increased significantly. Once a ship crashes, emergency rescue and salvage operations at sea are particularly important. Among them, the hydraulic synchronous lifting system, as one of the salvage technologies with high output and high efficiency, is now widely used in various salvage projects. However, offshore engineering is different from land. It is carried out on barges. Due to the existence of sea conditions, during the construction process, barges will generate random wave motions, and there will be uneven force on the steel cables. Therefore, it is difficult to guarantee the synchronous lifting process. , the more dangerous situation is the occurrence of marine accidents. In order to solve this problem, people began to study the function of the heave compensation device in the process of synchronous lifting and how to perform heave compensation efficiently. For this purpose, a simulated double-barge synchronous lifting system was built. test platform.
现有技术中，有一种关于驳船升沉补偿的模拟实验平台。实验平台包括驳船Ⅰ模拟钢板、驳船Ⅱ模拟钢板、沉船模拟钢板和两个模拟运动平台，驳船Ⅰ模拟钢板和驳船Ⅱ模拟钢板分别固定在两个模拟运动平台上，承载驳船Ⅰ模拟钢板的模拟运动平台是六自由度运动平台，六自由度运动平台包括六个电动缸、一个下平台和一个上平台，六个电动缸的缸筒通过万向节与下平台连接，下平台固定在钢板地基上，活塞杆通过虎克铰与上平台下面连接，驳船Ⅰ模拟钢板中后部通过螺钉固定在上平台上面，驳船Ⅰ模拟钢板的前部伸出六自由度运动平台，驳船Ⅰ模拟钢板前部设有两个补偿液压缸，补偿液压缸的缸筒通过补偿液压缸虎克铰与驳船Ⅰ模拟钢板前部下面连接，补偿液压缸的活塞杆通过补偿液压缸关节轴承与沉船模拟钢板上面的两个角处相连，承载驳船Ⅱ模拟钢板的模拟运动平台是二自由度运动平台，上设有两个动力液压缸，一根支撑柱、支撑柱上端通过支撑柱虎克铰铰接在驳船模拟钢板Ⅱ下面的中心处，动力液压缸的缸筒通过动力液压缸关节轴承与地基钢板连接，活塞杆通过动力液压缸虎克铰与驳船钢板Ⅱ后部的下面铰接，驳船Ⅱ模拟钢板前部伸出模拟运动平台，驳船Ⅱ模拟钢板前部设有两个补偿液压缸，补偿液压缸的缸筒通过补偿液压缸虎克铰与驳船Ⅱ模拟钢板前部下面连接，补偿液压缸的活塞杆通过补偿液压缸关节轴承与沉船模拟钢板上面的两个角处相连，电动缸、补偿液压缸和动力液压缸与液压控制系统连接。现有驳船升沉补偿的模拟实验平台的不足是：一、在真实打捞过程中，驳船与沉船的连接属于柔性连接，一般采用比较粗的钢缆连接，而该试验平台整体结构属于刚性连接，驳船钢板与沉船钢板连接用的是液压缸，显然驳船的运动对沉船的运动影响在该试验平台上不能有效的体现出来，对升沉补偿策略的分析会有一定的影响；二、由于该实验平台中，补偿液压缸与沉船钢板采用的是铰接结构，因此沉船钢板的运动必然会受到自由度的限制，这与真实打捞过程中沉船的被动运动不相符合，达不到模拟目的；三、整个试验平台只能模拟升沉补偿过程，而在真实打捞过程中，升沉补偿的作用是体现在同步提升过程当中，该试验平台没有同步提升这一过程，因此，真实的打捞过程无法完全模拟；四、真实打捞过程中，采用的是多组液压提升机构同时提升，显然由于驳船的波浪运动，会导致提升钢缆受力不均的现象，该试验平台只有两组液压缸，无法体现这一打捞情况，从而对打捞过程的模拟不足。In the prior art, there is a simulation experiment platform for barge heave compensation. The experimental platform includes barge I simulated steel plate, barge II simulated steel plate, shipwreck simulated steel plate and two simulated motion platforms. The platform is a six-degree-of-freedom motion platform. The six-degree-of-freedom motion platform includes six electric cylinders, a lower platform and an upper platform. The cylinder barrels of the six electric cylinders are connected to the lower platform through universal joints, and the lower platform is fixed on the steel plate foundation. , the piston rod is connected to the lower part of the upper platform through a Hooke hinge, the middle and rear part of the barge I simulation steel plate is fixed on the upper platform by screws, the front part of the barge I simulation steel plate protrudes from the six-degree-of-freedom motion platform, and the front part of the barge I simulation steel plate is set There are two compensation hydraulic cylinders. The cylinder barrel of the compensation hydraulic cylinder is connected with the lower part of the front part of the barge I simulation steel plate through the compensation hydraulic cylinder Hooke hinge. Connected at the corners, the simulated motion platform carrying the barge II simulated steel plate is a two-degree-of-freedom motion platform with two power hydraulic cylinders, a support column, and the upper end of the support column is hinged under the barge simulated steel plate II through the support column Hooke hinge At the center of the power hydraulic cylinder, the cylinder barrel of the power hydraulic cylinder is connected to the foundation steel plate through the joint bearing of the power hydraulic cylinder, and the piston rod is hinged to the lower part of the rear part of the barge steel plate II through the Hooke hinge of the power hydraulic cylinder, and the front part of the simulated steel plate of the barge II is extended to simulate movement There are two compensation hydraulic cylinders on the front of the platform and barge II simulation steel plate. The cylinder barrel of the compensation hydraulic cylinder is connected to the lower part of the front part of the barge II simulation steel plate through the Hooke hinge of the compensation hydraulic cylinder. The piston rod of the compensation hydraulic cylinder passes through the joint of the compensation hydraulic cylinder. The bearings are connected with the two corners on the shipwreck simulation steel plate, and the electric cylinder, compensation hydraulic cylinder and power hydraulic cylinder are connected with the hydraulic control system. The deficiencies of the existing barge heave compensation simulation test platform are: 1. In the actual salvage process, the connection between the barge and the sunken ship is a flexible connection, which is usually connected by relatively thick steel cables, while the overall structure of the test platform is a rigid connection. The steel plate of the barge and the steel plate of the sunken ship are connected by a hydraulic cylinder. Obviously, the influence of the motion of the barge on the motion of the sunken ship cannot be effectively reflected on the test platform, which will have a certain impact on the analysis of the heave compensation strategy; In the platform, the compensation hydraulic cylinder and the sunken steel plate adopt a hinged structure, so the movement of the sunken steel plate is bound to be limited by the degree of freedom, which is inconsistent with the passive movement of the sunken ship in the actual salvage process, and the simulation purpose cannot be achieved; 3. The entire test platform can only simulate the heave compensation process, but in the actual salvage process, the effect of heave compensation is reflected in the synchronous lifting process. This test platform does not have a synchronous lifting process, so the real salvage process cannot be completely simulated 4. In the actual salvage process, multiple sets of hydraulic lifting mechanisms are used to lift simultaneously. Obviously, due to the wave motion of the barge, the force on the lifting cables will be uneven. The test platform only has two sets of hydraulic cylinders, which cannot reflect this. A salvage situation, so the simulation of the salvage process is insufficient.

1、用液压千斤顶同步提升技术，既可以对任何随机海况下进行没有升沉补偿的同步提升过程的模拟，包括驳船的波浪运动以及沉船的被动运动，查看没有补偿的情况下，海况对沉船的影响以及钢丝绳的提升力变化情况，也可以通过对升沉补偿策略的研究，研究升沉补偿策略对同步提升的作用，给实际的打捞工程的升沉补偿技术提供实数据与理论支持。1. Using the hydraulic jack synchronous lifting technology, it is possible to simulate the synchronous lifting process without heave compensation under any random sea conditions, including the wave motion of the barge and the passive motion of the sunken ship. Check the impact of the sea state on the sunken ship without compensation The effect of the heave compensation strategy and the change of the lifting force of the wire rope can also be studied through the study of the heave compensation strategy to study the effect of the heave compensation strategy on synchronous lifting, and provide real data and theoretical support for the heave compensation technology of the actual salvage project.
2、试验台将机电、控制技术集中于一体，实验平台占地面积小，节约成本，灵活方便，便于实验设备管理。2. The test bench integrates electromechanical and control technologies, and the experimental platform occupies a small area, which saves costs, is flexible and convenient, and facilitates the management of experimental equipment.
3、两个模拟运动平台均采用六自由度平台，满足真实打捞情况下驳船的六个自由度运动，包括横摇、纵摇、艏摇、横荡、纵荡、升沉。3. Both simulated motion platforms adopt six-degree-of-freedom platform, which can meet the six-degree-of-freedom movement of the barge under real salvage conditions, including roll, pitch, yaw, sway, surge, and heave.
