技术领域technical field

本发明涉及海洋工程技术领域,特别涉及一种多自由度补偿的海上风机整体吊装装置。The invention relates to the technical field of ocean engineering, in particular to an integral hoisting device for offshore wind turbines with multi-degree-of-freedom compensation.

背景技术Background technique

风能作为一种清洁的可再生能源,特别是海上风能,在世界能源结构中发挥重要作用,在可再生资源中占据主导地位,其开发和利用越来越被人们重视。目前用于海上风机安装的船舶主要有两大类,一类是自升式风机安装船或平台,另一类是浮式安装船。自升式安装船或平台受风浪影响较浮式安装船小,但其受水域、水深的限制;浮式安装船则不受水深的影响,但受风浪的影响较自升式安装船大。随着风电场的发展,风机安装逐渐向深水域发展,由于自升式安装船或平台受水深限制,并且在淤泥质海床,桩脚较难保持平衡,此时,大型浮式安装船就显示出优势了,其不受水域、水深限制,在不同风机位置间的转移速度快,操纵性好,机动性强。但由于风浪因素限制了浮式安装船的使用范围,其安装作业必须在小风浪条件下才能进行。因此如何降低风浪对浮式安装船的影响,提高安装作业中风机的稳定性和可控性成了目前需要迫切解决的问题。As a clean and renewable energy, wind energy, especially offshore wind energy, plays an important role in the world's energy structure and occupies a dominant position among renewable resources. People pay more and more attention to its development and utilization. At present, there are two main types of ships used for offshore wind turbine installation, one is the self-elevating wind turbine installation ship or platform, and the other is the floating installation ship. Jack-up installation vessels or platforms are less affected by wind and waves than floating installation vessels, but are limited by water area and water depth; floating installation vessels are not affected by water depth, but are more affected by wind and waves than jack-up installation vessels. With the development of wind farms, the installation of wind turbines is gradually developing in deep waters. Since the jack-up installation vessel or platform is limited by the water depth, and on the muddy seabed, it is difficult to keep the pile feet in balance. At this time, the large floating installation vessel is It has shown its advantages. It is not limited by the water area and water depth. The transfer speed between different fan positions is fast, the maneuverability is good, and the maneuverability is strong. However, due to the wind and wave factors that limit the range of use of the floating installation vessel, its installation work must be carried out under small wind and wave conditions. Therefore, how to reduce the impact of wind and waves on floating installation vessels and improve the stability and controllability of wind turbines during installation operations has become an urgent problem to be solved.

发明内容Contents of the invention

This brings great difficulty to the positioning and centering of the fan, and the impact phenomenon between the fan and the foundation often occurs. The present invention jointly controls the attitude of the whole wind turbine through the motion compensation system of the upper lifting point and the positioning and centering system of the lower wind turbine, so that the wind turbine can generate compensation motion with six degrees of freedom to counterbalance the sway and heave of the ship, thereby improving the performance of the wind turbine in wind and waves. stability, and to achieve positioning and alignment of fans and fan foundations.

(5)本发明通过设置V型吊索撑杆机构,使可伸缩吊臂的伸缩运动与起吊系统解耦,在起吊系统不动作的情况下,可伸缩吊臂的水平伸缩运动并不会影响到风机垂直方向的高度变化。(5) The present invention decouples the telescopic movement of the telescopic boom from the lifting system by setting a V-shaped suspension rod mechanism. When the lifting system does not operate, the horizontal telescopic movement of the telescopic boom will not affect the The height change to the vertical direction of the wind turbine.

The pulley mechanism on the arm 2 is then connected to both ends of the upper balance beam 14 , and the bottom of the upper balance beam 14 is connected to the lower balance beam 9 through a steel cable 23 .

具体地,如图4至图6所示,所述上部吊点运动补偿系统包括两个可伸缩吊臂2,两个可伸缩吊臂2分别通过球铰链19左右对称地安装在所述船体的吊架1的左右立柱20上,通过控制所述可伸缩吊臂2的伸缩运动来实现吊点沿船舶纵向方向的运动补偿,所述液压驱动装置包括两个水平补偿液压缸3和两个垂向补偿液压缸4,所述水平补偿液压缸3和所述可伸缩吊臂2布置在同一水平面上,两个水平补偿液压缸3的一端分别通过球铰链19与吊架1的上横梁21中部相连接,另一端分别与两个可伸缩吊臂2内侧面铰接,通过控制水平补偿液压缸的伸缩运动来带动可伸缩吊臂做水平方向的转动,实现吊点沿船舶横向方向的运动补偿,所述垂向补偿液压缸4安装在所述可伸缩吊臂2的正下方,两个垂向补偿液压缸4的一端分别通过球铰链与船体吊架1的左右立柱20相连,另一端分别与两个可伸缩吊臂2下侧面铰接,通过所述垂向补偿液压缸的伸缩运动来驱动可伸缩吊臂垂直方向转动,以此实现吊点垂直方向的运动补偿。总体说来,所述吊点运动补偿系统通过控制所述可伸缩吊臂2的上下、左右转动及前后伸缩运动来实现上部吊点的前后、左右、上下运动补偿,从而降低风浪因素对吊点的扰动,使上部吊点始终保持相对稳定状态。Specifically, as shown in Figures 4 to 6, the upper suspension point motion compensation system includes two telescopic booms 2, and the two telescopic booms 2 are symmetrically installed on the left and right sides of the hull through ball joints 19. On the left and right columns 20 of the hanger 1, the movement compensation of the lifting point along the longitudinal direction of the ship is realized by controlling the telescopic movement of the telescopic boom 2. The hydraulic drive device includes two horizontal compensation hydraulic cylinders 3 and two vertical compensation cylinders. To the compensation hydraulic cylinder 4, the horizontal compensation hydraulic cylinder 3 and the telescopic boom 2 are arranged on the same horizontal plane. The other ends are respectively hinged with the inner sides of the two telescopic booms 2, and the telescopic boom is driven to rotate in the horizontal direction by controlling the telescopic movement of the horizontal compensation hydraulic cylinder, so as to realize the motion compensation of the lifting point along the transverse direction of the ship. The vertical compensation hydraulic cylinder 4 is installed directly below the telescopic boom 2, and one end of the two vertical compensation hydraulic cylinders 4 is respectively connected to the left and right columns 20 of the hull hanger 1 through a ball hinge, and the other end is connected to the left and right columns of the hull hanger 1 respectively. The lower sides of the two telescopic booms 2 are hinged, and the telescopic movement of the vertical compensation hydraulic cylinder is used to drive the telescopic booms to rotate in the vertical direction, thereby realizing motion compensation in the vertical direction of the lifting point. Generally speaking, the suspension point motion compensation system realizes the front, rear, left and right, up and down motion compensation of the upper suspension point by controlling the up and down, left and right rotation and front and rear telescopic movement of the telescopic boom 2, thereby reducing the impact of wind and wave factors on the suspension point. The disturbance keeps the upper lifting point in a relatively stable state.

具体地,如图5所示,所述起吊载荷动态匹配系统包括两根主承载钢缆5、两根主承载弹簧6、两个主承载液压缸7和两个滑轮8,所述主承载钢缆5一端与所述可伸缩吊臂2的中上部连接,另一端绕过吊架1的左右立柱20顶部的滑轮8后,通过所述主承载弹簧6和所述主承载液压缸7相连,所述主承载液压缸7再通过球铰链19与吊架平台22相连,通过实时控制所述主承载液压缸7的伸缩来实现所述主承载钢缆5的拉力与起吊载荷的动态匹配,从而最大限度降低所述垂向补偿液压缸4的受力,因此大大提高了垂向补偿液压缸4的响应速度,使风机在垂直方向的升沉补偿响应迅速,从而使风机和基础的垂向抨击这一关键问题得到最大的限制。Specifically, as shown in Figure 5, the dynamic matching system for lifting loads includes two main bearing steel cables 5, two main bearing springs 6, two main bearing hydraulic cylinders 7 and two pulleys 8, the main bearing steel One end of the cable 5 is connected to the middle and upper part of the telescopic boom 2, and the other end bypasses the pulleys 8 on the top of the left and right columns 20 of the hanger 1, and is connected to the main bearing hydraulic cylinder 7 through the main bearing spring 6, The main bearing hydraulic cylinder 7 is connected to the hanger platform 22 through a ball joint 19, and the dynamic matching between the pulling force of the main bearing steel cable 5 and the lifting load is realized by controlling the expansion and contraction of the main bearing hydraulic cylinder 7 in real time, so that The force of the vertical compensation hydraulic cylinder 4 is minimized, so the response speed of the vertical compensation hydraulic cylinder 4 is greatly improved, and the heave compensation of the fan in the vertical direction responds quickly, so that the vertical impact of the fan and the foundation This critical issue is maximally constrained.

本实施例中,通过实时检测垂向补偿液压缸4的受力作为主承载液压缸7的反馈控制信号。其工作原理是:当垂向补偿液压缸4受压时,主承载液压缸7往回缩并拉伸主承载弹簧6,使主承载钢缆5增加拉力,以此来分担垂向补偿液压缸4的承载力,使其所受压力变小;当垂向补偿液压缸4受拉时,主承载液压缸7往前伸长,减少主承载弹簧6的拉伸量,并使主承载钢缆5的拉力变小,以此来释放垂向补偿液压缸4的拉力,使其所受拉力变小。换种说法就是,当所述垂向补偿液压缸4往上顶使所述可伸缩吊臂2向上转动时,所述起吊载荷动态匹配系统能检测到所述垂向补偿液压缸4的压应力,马上协助所述垂向补偿液压缸4一起往上拉,使所述可伸缩吊臂2向上转动;当所述垂向补偿液压缸4往下拉使所述可伸缩吊臂2向下转动时,所述起吊载荷动态匹配系统检测到所述垂向补偿液压缸4的拉应力,马上减少自身的拉力以配合所述垂向补偿液压缸4,使所述可伸缩吊臂2迅速向下转动,因此两种情况都大大增加了所述垂向补偿液压缸4的响应速度。In this embodiment, the force of the vertical compensation hydraulic cylinder 4 is detected in real time as the feedback control signal of the main bearing hydraulic cylinder 7 . Its working principle is: when the vertical compensation hydraulic cylinder 4 is under pressure, the main bearing hydraulic cylinder 7 retracts and stretches the main bearing spring 6, so that the main bearing steel cable 5 increases the tension, so as to share the vertical compensation hydraulic cylinder 4, so that the pressure on it becomes smaller; when the vertical compensation hydraulic cylinder 4 is pulled, the main bearing hydraulic cylinder 7 stretches forward, reducing the stretching amount of the main bearing spring 6, and making the main bearing steel cable The pulling force of 5 becomes smaller, releases the pulling force of vertical compensating hydraulic cylinder 4 with this, makes its suffer pulling force smaller. In other words, when the vertical compensation hydraulic cylinder 4 pushes up to make the telescopic boom 2 rotate upward, the lifting load dynamic matching system can detect the compressive stress of the vertical compensation hydraulic cylinder 4 , immediately assist the vertical compensation hydraulic cylinder 4 to pull up together, so that the telescopic boom 2 turns upward; when the vertical compensation hydraulic cylinder 4 pulls down to make the telescopic boom 2 turn downward , the lifting load dynamic matching system detects the tensile stress of the vertical compensation hydraulic cylinder 4, and immediately reduces its own tension to cooperate with the vertical compensation hydraulic cylinder 4, so that the telescopic boom 2 rotates downward quickly , so both cases greatly increase the response speed of the vertical compensation hydraulic cylinder 4 .

具体地,如图7所示,所述下平衡梁9中部通过夹紧装置锁死风机立柱底部,两端则依次通过四个所述弹簧缓冲器10、两对呈八字布置的所述定位牵索11绕过滑轮8后连接到四台所述定位绞车12上,通过控制四根所述定位牵索11的收放来带动风机底部产生水平面的移动和绕垂直轴的转动,从而增加了风机底部的可控性,大大减少了传统吊装船上风机的“单摆运动”,并以此来实现风机底部和风机基础的准确定位与对中。Specifically, as shown in FIG. 7 , the middle part of the lower balance beam 9 locks the bottom of the fan column through a clamping device, and the two ends pass through four spring buffers 10 and two pairs of positioning pulleys arranged in a figure-eight arrangement. The cable 11 is connected to the four positioning winches 12 after bypassing the pulley 8, and the movement of the horizontal plane and the rotation around the vertical axis at the bottom of the fan are driven by controlling the retraction and retraction of the four positioning cables 11, thereby increasing the fan speed. The controllability of the bottom greatly reduces the "single pendulum movement" of the wind turbine on the traditional hoisting ship, and uses this to realize the accurate positioning and alignment of the bottom of the wind turbine and the foundation of the wind turbine.

本实施例中,通过收紧其中两根对角线上的所述定位牵索11,可使风机绕垂直轴做某个方向的转动,而收紧另外两根对角线上的所述定位牵索11,则可产生相反方向的转动;需要平移时,则通过收紧相邻两根所述定位牵索11来实现。In this embodiment, by tightening the positioning cables 11 on two of the diagonals, the fan can be rotated in a certain direction around the vertical axis, while tightening the positioning cables 11 on the other two diagonals. The guy wires 11 can rotate in the opposite direction; when translation is required, it can be realized by tightening two adjacent positioning guy wires 11 .

总之,本实施例通过设置上部吊点运动补偿系统和下部风机定位系统,使风机13上下部位置都能得到控制,并在两个系统的联合作用下,可使风机13产生六个自由度的运动,从而大大增加了风机的可控性和灵活性。In a word, in this embodiment, by setting the upper lifting point motion compensation system and the lower fan positioning system, the upper and lower positions of the fan 13 can be controlled, and under the joint action of the two systems, the fan 13 can generate six degrees of freedom. Movement, thus greatly increasing the controllability and flexibility of the fan.

Lifting winch 18.

另外,还包括两个中间设置有转动关节的V型吊索撑杆17,所述吊索撑杆17两端通过设有铰轴的转动关节活动连接在可伸缩吊臂2两端的内侧面,所述吊索撑杆17的每个转动关节上都安装有滑轮8供所述起吊索16依次通过,所述吊索撑杆17 在垂直面上随可伸缩吊臂的伸缩而开合,使可伸缩吊臂2的伸缩运动与起吊系统解耦,在起吊系统不动作的情况下,可伸缩吊臂2的水平伸缩运动并不会影响到风机垂直方向的高度变化。In addition, it also includes two V-shaped sling struts 17 with rotating joints in the middle, and the two ends of the slinging struts 17 are movably connected to the inner surfaces of the two ends of the telescopic boom 2 through the rotating joints provided with hinge shafts. A pulley 8 is installed on each rotating joint of the sling strut 17 for the sling 16 to pass through in turn, and the sling strut 17 opens and closes with the expansion and contraction of the telescopic boom on the vertical plane, so that The telescopic movement of the telescopic boom 2 is decoupled from the hoisting system, and the horizontal telescopic movement of the telescopic boom 2 will not affect the vertical height change of the wind turbine when the hoisting system does not operate.
